Hand-held beverage dispenser and related features and accessories

Abstract

A hand-held beverage dispenser includes a handle body, within which multiple valve units are contained. Two sets of fluid flow paths are provided into the handle body. The sets of fluid flow paths are mutually exclusive one to the other. Each flow path of the first set is in fluid communication with each valve unit, whereas only a predetermined one of the second set of fluid flow paths is in fluid communication with each valve unit. Each valve unit includes a flow control valve and a selection valve. The selection valve determines on an ad hoc basis which of the first set of flow paths will be utilized at any given time, while the flow control valve provides single action simultaneous ON-OFF control of fluid flows through both the selected flow path and the predetermined flow path.

BACKGROUND ART: Post-mix type hand-held beverage dispensers, such as are often referred to as bar guns or soda guns are well known conveniences in the food and bar service industries, enabling beverages to be prepared as they are dispensed by mixing together a beverage product, such as, for example, a syrup or like concentrate, and a diluent, such as, for example, plain water or carbonated water. Although each of the variously utilized diluents is typically appropriate for use with a great variety' of beverage products, any one beverage product will generally only be compatible with a particular diluent. Unfortunately, this presents a problem for currently available hand-held beverage dispensers implemented according to the current state of the art. In particular, the currently available hand-held beverage dispensers are simply not capable of readily changing the diluent to be utilized with respect to any particular fluid flow path through the dispenser. Accordingly, a hand-held post-mix type drink dispenser readily configurable to dispense any available diluent in connection with any beverage product flow path will create, and meet, new demand in the drink dispensing industry. DISCLOSURE OF THE INVENTION: A hand-held beverage dispenser for selectively dispensing a demanded one of a plurality of post-mix beverages generally comprises a handle body; a plurality of valve units contained substantially within the extents of said handle body; a first plurality of normally closed fluid flow paths from without to within said handle body; and a second plurality7 of normally closed fluid flow paths from without to within said handle body. The second plurality’ of fluid flow paths are mutually exclusive of the first plurality of fluid flow7 paths being mutually exclusive. Each of the first plurality7 of fluid flow7 paths is in fluid communication with each valve unit, w'hereas only a predetermined one of the second plurality of fluid flow7 paths is in fluid communication with each valve unit. Each valve unit comprises both a flow7 control valve and a selection valve. The selection valve determines on an ad hoc basis which of the first plurality of flow paths will be utilized at any given time, while the flow7 control valve provides single action simultaneous ON-OFF control of fluid flows through both the selected flow path and the predetermined flow7 path Many other features, objects and advantages of the present invention will be apparent to those of ordinary skill in the relevant arts, especially in light of the foregoing discussions and the following drawings, exemplary detailed description and appended claims.

BEST MODE FOR CARRYING OUT THE INVENTION: Although those of ordinary skill in the art will readily recognize many alternative embodiments, especially in light of the illustrations provided herein, this detailed description is exemplary' of the preferred embodiment of the present invention - a hand-held beverage dispenser and related features and accessories, the scope of which is limited only by the claims appended hereto; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Figures are not necessarily to scale, and some features may be exaggerated to show details of particular components or steps. As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Figures are not necessarily to scale, and some features may be exaggerated to show details of particular components or steps. Referring now to the figures, and to Figures 1-3 in particular, the preferred implementation, according to the present invention, of a hand-held beverage dispenser 10 is showm to generally comprise a handle body 11, which, as will be better understood further herein, houses a novel piping system 22 (shown in detail in Figures 7-62), and a post-mix type drink dispenser assembly 104, which, as showm in the figures, is dependently coupled to the bottom 15 of the handle body 11 at a location adjacent the forward end 18 of the handle body 11. As will be readily appreciated by those of ordinary skill in the relevant arts, the depicted hand-held beverage dispenser 10 is of the well-know class of dispensers often referred to as bar guns or soda guns. In any case, and like the dispensers of its class, the hand-held beverage dispenser 10 of the present invention is intended for use in dispensing -on demand - a variety of post-mix beverages. As is w'ell-known to those of ordinary skill in the art, such post-mix beverages are prepared as they are dispensed by mixing together a beverage product, such as, for example, a syrup or other concentrate, and a diluent, such as, for example, plain water or carbonated water. Although, and as will be described in greater detail further herein, at least some preferred implementations of the present invention contemplate the provision of a universal handle body 11 and piping system 22 suitable for use with any of a wide range of implementations for the post-mix type drink dispenser assembly 104, details of an exemplary' post-mix type drink dispenser assembly, which operates in a manner consistent with the present invention for the provision of post-mix beverages, are shown and described in U.S. patent application Serial No. 16 / 394,889 fiied Apni 25, 2019 for METHODS AND APPARATUS FOR POST-MIX DRINK DISPENSING, which, by this reference, is incorporated herein as though now set forth in its entirety. Regardless of the technical details involved in mixing post-mix beverages, however, it should be noted that while each of the various utilized diluents is typically appropriate for use with a great variety of beverage products, any one beverage product will generally only be compatible with a particular diluent. In a leap forward for the relevant arts, the novel piping system 22 of the present invention provides various flow paths through the hand-held beverage dispenser 10 between a plurality of fluid inlets 23 to the piping system 22 and a plurality of fluid outlets 36 (shown, for example, in Figure 7) from the piping system 22, wherein at least some of the flow paths are selectively established. In particular, as will be better understood in the details set forth further herein, the novel piping system 22 of the present invention is adapted to enable, for each of a plurality of provided beverage products, end-user selection of any one of a plurality of provided diluents, whereafter the selected diluent is dispensed concurrently with the beverage product for which the selection has been made. As shown in the figures, the plurality of fluid inlets 23 is provided at the rear end 20 of the handle body 11, and, for the depicted exemplary implementation, includes a first diluent inlet 24 and a second diluent inlet 25, although, it is noted, the teachings of the present invention may be relied upon, within the ordinary skill in the relevant arts, to expand the number of diluent inlets to three or more. Furthermore, some aspects of the present invention apply to beverage systems utilizing only one diluent, hi any case, the plurality of fluid inlets 23 also includes a plurality of beverage product inlets 26a-26h, there being provided one beverage product inlet 26a-26h for each of the number of beverage products for which an implementation of the hand-held beverage dispenser 10 is capable of dispensing on demand. As w ill be appreciated by those of ordinary skill in the art, in light of this exemplary' description, the implemented number of beverage product inlets may vary widely with such considerations as requirements of the intended commercial market, desired limits on the size or shape of the hand-held beverage dispenser 10, manufacturing cost, and the like. At this juncture it is noted that the rear end 20 of the exemplary handle body 11 is, for clarity, depicted sans aesthetic covering, and, for generality, depicted without any particular interface to an external flow’ control and manifold system. As is well known in the relevant arts, dispensers of the class to which the hand-held beverage dispenser 10 of the present invention belongs generally operate to dispense a mixture of a desired beverage product and its corresponding appropriate diluent in a single-button, ON-OFF type operation, and therefore generally do not include features for pressure regulation and the like. As a result and as also well known in the relevant arts, such dispensers are supplied with fluids through any of many readily commercially available How control and manifold assemblies. These assemblies serve to supply fluids at appropriately regulated pressures, and are typically connected to a hand-held beverage dispenser through a multiplicity of individual fluid lines. The individual fluid lines from a flow’ control and manifold assembly are typically collected within an elongate sheath tube, which, along with the fluid lines, terminates at a connector sized, shaped and otherwise adapted to provide a fluid-tight interface between each fluid line and each fluid inlet of the hand-held beverage dispenser, in this case the fluid inlets 23 disposed at the rear end 20 of the handle body 11 of the hand-held beverage dispenser 10. As will be appreciated by those of ordinary skill in the art, the fluid inlets 23 are readily provided with any additional connector hardware as may be required to connect to the fluid lines from the flow control and manifold system. Additionally, however, it is also noted that the flow control and manifold systems provide a capability for changing, on an ad hoc basis, the particular beverage product associated with a particular fluid line, and hence supplied to the respective beverage product inlet 26a-26h. Although such changes may be carried out without affecting operation through any other fluid line of the dispenser, any particular change is subject to the ability of the newly supplied beverage product io be mixed with an appropriate diluent. As will be described in greater detail further herein and shown, for example, in Figure 7, the previously mentioned plurality of fluid outlets 36 is provided at the bottom 15, and adjacent the forward end 18, of the handle body 11, where the outlets 36 are placed and arranged to conduct dispensed fluids to the post-mix type drink dispenser assembly 104. For the depicted exemplary implementation, the fluid outlets 36 include a single, common diluents outlet 37, and a plurality of beverage product outlets 38a-38h, there being provided one beverage product outlet 38a-38h for, and corresponding to, each one of the provided beverage product inlets 26a-26h. As will be described in detail further herein, the hand-held beverage dispenser 10 of the present invention is adapted to dispense a beverage fluid, as supplied under suitable pressure from a flow control and manifold assembly and through one of the beverage product inlets 26a-26b, from a corresponding one of the beverage product outlets 38a-38h, and into the post-mix type drink dispenser assembly 104. Additionally, the hand-held beverage dispenser 10 of the present invention is adapted to concurrently dispense either the first diluent, as supplied under suitable pressure from the flow control and manifold assembly, or other source, and through the first diluent inlet 24, or, in the alternative, the second diluent, as supplied under suitable pressure from the flow control and manifold assembly, or other source, and through the second diluent inlet 25, from the single, common diluent outlet 37, and into the post-mix type drink dispenser assembly 104 where the end-user selected first or second diluent is mixed with the simultaneously dispensed beverage product. Although, as shown in Figure 7, the exemplary implementation of the present invention comprises a single, common diluent outlet 37, a plurality’ of separate diluent outlets (for example, one for each diluent) may also be implemented within the scope of the present invention. Because, as will be discussed in detail with reference to Figures 7-63, the provision of either the first or second diluent is end-user selectable on a per beverage product inlet 26a-26h basis (equivalently described as on a per beverage product outlet 38a-38h basis), the correct diluent may readily be dispensed for any beverage product flowing through any beverage product inlet 26a-26h (beverage product outlet 38a-38h). What is more, and in an important advance over the prior art, end-user selection of the first or second diluent is accomplished without disassembly of the hand-held beverage dispenser 10, depressurization of any flow path through the hand-held beverage dispenser 10 or its fluids-supplying flow' control and manifold assembly, or any other disruption of the operation of the hand-held beverage dispenser 10. Finally, the general operation of the hand-held beverage dispenser 10 of the present invention substantially adheres to the simple operation familiar to countless service industry employees worldwide. As shown in the figures, a set of flow controls 14a-14h is provided at the top 12 of the handle body 11 of the hand-held beverage dispenser 10, a single flow' control 14a-14h being for and corresponding to beverage product introduced through one each of the provided beverage product inlet 26a-26h for dispensing from the also corresponding beverage product outlet 38a~38h. As will be better understood further herein, how'ever, the most preferred implementation of the hand-held beverage dispenser 10 of the present invention additionally includes a pair of flow controls 14i, 14j, each dedicated to dispensing a diluent only. What is more, in at least the most preferred implementation of the present invention, the provision of either the first or second diluent is also end-user selectable for each of flow’ controls 14i-14j. In any case, simply depressing a flow' control 14a-l4j will cause flow' of either a beverage product and its corresponding selected diluent, or a diluent alone. To ensure ease of handling and comfortable use of the hand-held beverage dispenser 10, the handle body 11 is most preferably ergonomically contoured about the sides 16 and bottom 15 to provide a secure, ambidextrous grip 17 for the end-user as the post-mix type drink dispenser assembly 104 is held steady over a beverage vessel while any of the flow controls 14a-14j is actuated (typically by thumb press). As particularly shown in Figures 4-5, and also typical of the class of dispensers to which the hand-held beverage dispenser 10 belongs, a nozzle housing 122 for the mixer 105 (described in greater detail further herein) of the implemented exemplary' post-mix type drink dispenser assembly 104 is readily removable to facilitate periodic cleaning of the post-mix type drink dispenser assembly 104. To this end, as shown in the figures, the upper portion 124 of the inner surface 123 of the nozzle housing 122 is provided with a plurality of locking tabs 12.5 operably adapted to engage mating nozzle housing locking members 112 provided about a portion of the mixer 105. As shown in the figures, and as will be familiar to those of ordinary skill in the art as well as to service industry employees in general, the nozzle housing 122 locks in place with a partial twist about the mixer 105 in the clockwise direction, and is similarly released with a partial twist about the mixer 105 in the counterclockwise direction. Although, as above noted, Applicant has taken effort to ensure that the preferred implementation of the hand-held beverage dispenser 10 of the present invention retains a familiar manner of operation, the preferred implementation exceeds the level of maintainability of prior art dispensers. For example, although prior art dispensers include such features as the above-described removable nozzle housing 122, as shown in Figures 4-5, conventional dispensers of the relevant class implement limited, at best, features for maintainability of the remainder of the provided drink dispenser assembly, which in the typical prior art device is either unitary' with the handle body or so highly integral therewith as to make removal or disassembly for maintenance impractical if not wholly impossible. To be sure, Applicant knows of no prior art implementation of a bar gun wherein the entire provided nozzle assembly is readily removable from the bar gun. As will be better understood further herein, provision is made in the most preferred implementation of the hand-held beverage dispenser 10 of the present invention for the simple removal from the handle body 11 of the entire post-mix type drink dispenser assembly 104, whereafter the removed dispenser assembly 104 may be replaced or repaired. In addition to dramatically increasing the maintainability’ of the hand-held beverage dispenser 10 of the present invention, this aspect of the present invention also enables flexibility in the development of a commercial offering by allowing use of any number of differently designed dispenser assemblies with a single design of handle body and piping system. As previously noted, the hand-held beverage dispenser 10 of the present invention includes a novel piping system 22, which is housed within the previously described handle body 11. Broadly described, the piping system 22 comprises a number of fluid conduits at various fluid inlets 23, as shown in Figure 6, or terminating at various fluid outlets 36, as shown in Figure 7. Additionally, however, the piping system 22 comprises a plurality of valve units 39a-39j, each of which will be shown and described in greater detail further herein, interposed between the fluid conduits from the fluid inlets 23 and the fluid conduits to the fluid outlets 36. In the exemplary implementation, each such valve unit 39a-39j is implemented about a corresponding valve body 40a-40j, as shown in Figures 7-8, and, as will be better understood further herein, together implement the previously mentioned novel end-user selective establishment of various flow paths through the hand-held beverage dispenser 10 of the present invention . Although other methods of manufacturing are possible in accordance with the teachings of the present invention, the complex structure of the most preferred implementation of the hand-held beverage dispenser 10 of the present invention is created using additive manufacturing. In particular, it is particularly advantageous to 3-D print the valve bodies 40a-40j, and all of the fluid conduits of the piping system 22, unitary with the all of the handle body 11 save base plate 92 (described further herein). Most preferably, these components are printed in stainless steel, which, as opposed to the utilization of many other possible materials of manufacture, such as, for example, plastics or resins, eliminates many concerns regarding the use of a potentially hazardous material. Additionally, the use of stainless steel facilitates routine cleaning, and also results in a durable product notwithstanding the challenging environment in which the hand-held beverage dispenser 10 will be used. Regardless of the selected material of construction, however, and as particularly shown in Figures 6-8, the most preferred method for additively manufacturing the housing body 11 and unitary internal structures thereof includes the provision of an internal mesh, or lattice, structure 21. As shown in the figures, the implemented internal mesh 21 suspends and fixes the valve bodies 40a-40j and fluid conduits in place substantially within the extents of the handle body 11. Implementation of the internal mesh 21 not only saves material cost, but also lessons the overall weight of the hand-held beverage dispenser 10, thereby increasing end-user satisfaction with the hand-held beverage dispenser 10. As will be better understood further herein, operation and / or maintenance of the hand-held beverage dispenser 10 of the present invention involves at least some limited access from without the handle body 11 to the various valve bodies 40a-40j housed within the handle body 11. To this end, as particularly shown in Figure 6, a plurality of valve stem holes 13 is provided through the top 12 of the handle body 11, to enable end-user interaction, through the previously discussed flow controls 14a-14j, with the piping system 22, as is necessary in the ordinary operation of the hand-held beverage dispenser 10. Similarly and as particularly shown in Figure 7, and best understood with reference to Figure 3, the base plate 92, which substantially forms the bottom 15 of the handle body 11, is selectively removable from the handle body 11, as may be necessary in the maintenance or deep cleaning of hand-held beverage dispenser 10, and which facilitates assembly of the valve units 39a-39j, which will be described in greater detail further herein. To doubly ensure clarity in the discussions to follow, it is at this juncture noted that in the exemplary implementation of the band-held beverage dispenser 10 of the present invention, as now described, beverage product inlet 26a is in fluid communication, through a correspondingly provided fluid conduit, with valve body 40a, and valve body 40a is in fluid communication, through a further correspondingly provided fluid conduit, with beverage product outlet 38a; beverage product inlet 26b is in fluid communication, through a correspondingly provided fluid conduit, with valve body 40b, and valve body 40b is in fluid communication, through a further correspondingly provided fluid conduit, with beverage product outlet 38b; beverage product inlet 26c is in fluid communication, through a correspondingly provided fluid conduit, with valve body 40c, and valve body 40c is in fluid communication, through a further correspondingly provided fluid conduit, with beverage product outlet 38c; beverage product inlet 26d is in fluid communication, through a correspondingly provided fluid conduit, with valve body 40d, and valve body 40d is in fluid communication, through a further correspondingly provided fluid conduit, with beverage product outlet 38d; beverage product inlet 26e is in fluid communication, through a correspondingly provided fluid conduit, with valve body 40e, and valve body 40e is in fluid communication, through a further correspondingly provided fluid conduit, with beverage product outlet 38e; beverage product inlet 261' is in fluid communication, through a correspondingly provided fluid conduit, with valve body 401', and valve body 401' is in fluid communication, through a further correspondingly provided fluid conduit, with beverage product outlet 38f; beverage product inlet 26g is in fluid communication, through a correspondingly provided fluid conduit, with valve body 40g, and valve body 40g is in fluid communication, through a further correspondingly provided fluid conduit, with beverage product outlet 38g; and beverage product inlet 26h is in fluid communication, through a correspondingly provided fluid conduit, with valve body 40h, and valve body 40h is in fluid communication, through a further correspondingly provided fluid conduit, with beverage product outlet 38h. Additionally, the first diluent inlet 24 is in fluid communication with each of the valve bodies 40a-40j through a corresponding shared fluid conduit, and the second diluent inlet 25 is in fluid communication with each of the valve bodies 40a-40j through a separate corresponding shared fluid conduit. Finally, each of the valve bodies 40a-40i is in fluid communication through yet a further fluid conduit with the single, common diluents outlet 37. Referring now to Figures 9-15, various details of the fluid conduits between the valve bodies 40a-40j and the various fluid inlets 23 and fluid outlets 36 are shown and described. In particular, Figures 9-15 detail the structural arrangement implementing the fluid conduits between beverage product inlets 26a-26h and valve bodies 40a-40h, and between valve bodies 40a-40b and beverage product outlets 38a-38h. In order to clearly depict these aspects of the present invention, however, the piping system 22 is, for clarity, depicted in these figures in partially cutaway views, each of which “cuts away” or otherwise omits the outer extents of the handle body 11 as well as the interconnecting mesh 21. That said, it is noted that the view of Figure 9 generally corresponds to the view of Figure 6; the view of Figure 10 generally corresponds to the view of Figure 7; and the view of Figure 15 generally corresponds to the view of 8. Additionally, it is noted that Figures 9-15, like Figures 6-8, each depict the piping system 22 of the exemplary preferred implementation with fully depopulated valve bodies 40a-40j --- that is, omitting the full detail of the valve units 39a-39j, which additional details will be fully shown and described further herein. As shown in the combmed Figures 9-15, an individual beverage product supply conduit 31a-31h is provided between each beverage product inlet 26a-26h and a corresponding one of the valve bodies 40a-40h. Although other shapes or implementations are possible, each beverage product supply conduit 31a~31h of the exemplary' preferred implementation comprises an elongate tubular member routed, within the confines of the extents of the handle body 11, between one of the beverage product inlets 26a-26h and its corresponding one of the valve bodies 40a-40h. In particular, beverage product supply conduit 31a is shown to provide fluid communication between beverage product inlet 26a and valve body 40a; beverage product supply conduit 31b is shown to provide fluid communication between beverage product inlet 26b and valve body 40b; beverage product supply conduit 31c is shown to provide fluid communication between beverage product inlet 26c and valve body 40c; beverage product supply conduit 3Id is shown to provide fluid communication between beverage product inlet 26d and valve body 40d; beverage product supply conduit 31e is shown to provide fluid communication between beverage product inlet 26e and valve body 40e; beverage product supply conduit 3 If is shown to provide fluid communication between beverage product inlet 26f and valve body’ 40f; beverage product supply conduit 31g is shown to provide fluid communication between beverage product inlet 26g and valve body 40g; and beverage product supply conduit 31h is shown to provide fluid communication between beverage product inlet 26h and valve body 40h. As shown in the figures, each beverage product supply conduit 31a-31h may interface with its respective valve body 40a-40h at any radial position about the respective valve body 40a-40h, the circumferential placement being largely a matter of accommodating each conduit within the very limited available space. On the other band, however, and as will be better understood further herein, it should at this point be noted that for the exemplary implementation of the present invention as now shown and described each beverage product supply conduit 31 a-3 Ih interfaces with its respective valve body 40a-40h at substantially the same vertical position from one valve body 40a-40h to another. To this end, as most clearly depicted in Figures 11, 12 and 15, the be verage product supply conduits 3 la-3 Hi are shown to terminate at a uniform vertical location in the upper midsection of the valve bodies 40a-40h. As also shown in the combined Figures 9-15, an individual beverage product dispensing conduit 35a-35h is provided between each valve body 40a-40h and a corresponding one of the beverage product outlets 38a-38h. Although other shapes or implementations are possible, each beverage product dispensing conduit 35a-35h of the exemplary' preferred implementation comprises an elongate tubular member routed, within the confines of the extents of the handle body 11, between one of the valve bodies 40a-40h and its corresponding one of the beverage product outlets 38a-38h. In particular, beverage product dispensing conduit 35a is shown to provide fluid communication between valve body 40a and beverage product outlet 38a; beverage product dispensing conduit 35b is shown to provide fluid communication between valve body 40b and beverage product outlet 38b; beverage product dispensing conduit 35c is shown to provide fluid communication between valve body 40c and beverage product outlet 38c; beverage product dispensing conduit 35d is shown to provide fluid communication between valve body 40d and beverage product outlet 38d; beverage product dispensing conduit 35e is shown to provide fluid communication between valve body 40e and beverage product outlet 38e; beverage product dispensing conduit 35f is shown to provide fluid communication between valve body 401'and beverage product outlet 38f; beverage product dispensing conduit 35g is shown to provide fluid communication between valve body 40g and beverage product outlet 38g; and beverage product dispensing conduit 35h is shown to provide fluid communication between valve body 40h and beverage product outlet 38h. As shown in the figures, each beverage product dispensing conduit 35a-35h - like the beverage product supply conduits 31a-31h - may interface with its respective valve body 40a-40h at any radial position about the respective valve body 40a-40h, the circumferential placement being largely a matter of accommodating each conduit within the very limited available space. On the other hand, however, and as will be better understood further herein, it should at this point be noted that for the exemplary implementation of the present invention as now shown and described each beverage product dispensing conduit 35a-35h - like each beverage product supply conduit 31a-31h - interfaces with its respective valve body 40a-40h at substantially the same vertical position from one valve body 40a-40h to another. The vertical position for the beverage product dispensing conduits 35a-35h, however, is vertically separated from the previously discussed vertical position for the beverage product supply-conduits 31a-31h. To this end, as most clearly depicted in Figures 11, 12 and 15, the beverage product dispensing conduits 35a-35h are shown to originate at a uniform vertical location adjacent the upper end of valve bodies 40a-40h, winch, as is shown in the figures, is a location vertically separate from the location at which the beverage product supply conduits 31a-31h terminate. As previously noted, the first diluent inlet 24 and the second diluent inlet 25 are each in fluid communication with each of the valve bodies 40a-40j through a respective shared fluid conduit. As particularly shown in Figure 16, a first diluent inlet manifold 126 includes a common trunk 127 in fluid communication with first diluent inlet 24, and a second diluent inlet manifold 28 includes a common trunk 29 in fluid communication with second diluent inlet 25. As shown in Figure 17, a plurality7 of valve supply branches 27a-27j is formed, or otherwise provided, in fluid communication with, and feed a first diluent from, common trunk 127, and a plurality of valve supply branches 30a-3Qj is formed, or otherwise provided, in fluid communication with, and feed a second diluent from, common trunk 29. As will be better understood further herein, there is provided one valve supply branch 27a-27j and one valve supply branch 30a-30j for each implemented valve unit 39a-39j. Although other shapes or implementations are possible, the first common trunk 127 and its corresponding valve supply branches 27a-27j of the exemplary preferred implementation of the first diluent inlet manifold 126 comprise an arrangement of generally elongate tubular members routed, within the handle body 11, between the first diluent inlet 24 and the valve bodies 40a-40j, as variously shown in combined Figures 9-15, 17 and 19-23. Likewise, and as also variously shown in combined Figures 9-15, 17 and 19-23, the second common trunk 29 and its corresponding valve supply branches 30a-30j of the exemplary preferred implementation of the second diluent inlet manifold 28 comprise an arrangement of generally elongate tubular members routed, within the handle body 11, between the second diluent inlet 25 and the valve bodies 40a-40j. As shown in Figures 17-21, valve supply branch 27a provides, for a first diluent introduced to common trunk 127 through first diluent inlet 24, fluid communication between common trunk 127 and valve body 40a, about which is implemented valve unit 39a, while valve supply branch 30a provides, for a second diluent introduced to common trunk 29 through second diluent inlet 25, fluid communication between common trunk 29 and valve body 40a. Valve supply branch 27b provides, for a first diluent introduced to common trunk 127 through first diluent inlet 24, fluid communication between common trunk 127 and valve body 40b, about which is implemented valve unit 39b, while valve supply branch 30b provides, for a second diluent introduced to common trunk 29 through second diluent inlet 25, fluid communication between common trunk 29 and valve body 40b. Valve supply branch 27c provides, for a first diluent introduced to common trunk 127 through first diluent inlet 24, fluid communication between common trunk 127 and valve body 40c, about which is implemented valve unit 39c, while valve supply branch 30c provides, for a second diluent introduced to common trunk 29 through second diluent inlet 25, fluid communication between common trunk 29 and valve body 40c. Valve supply branch 27d provides, for a first diluent introduced to common trunk 127 through first diluent inlet 24, fluid communication between common trunk 127 and valve body 40d, about which is implemented valve unit 39d, while valve supply branch 30d provides, for a second diluent introduced to common trunk 29 through second diluent inlet 25, fluid communication between common trunk 29 and valve body 40d. Valve supply branch 27e provides, for a first diluent introduced to common trunk 127 through first diluent inlet 24, fluid communication between common trunk 127 and valve body 40e, about which is implemented valve unit 39e, while valve supply branch 30e provides, for a second diluent introduced to common trunk 29 through second diluent inlet 25, fluid communication between common trunk 29 and valve body 40e. Valve supply branch 27f provides, for a first diluent introduced to common trunk 127 through first diluent inlet 24, fluid communication between common trunk 127 and valve body 40f, about which is implemented valve unit 39f, while valve supply branch 3Of provides, for a second diluent introduced to common trunk 29 through second diluent inlet 25, fluid communication between common trunk 29 and valve body 40f. Valve supply branch 27g provides, for a first diluent introduced to common trunk 127 through first diluent inlet 24, fluid communication between common trunk 127 and valve body 40g, about which is implemented valve unit 39g, while valve supply branch 30g provides, for a second diluent introduced to common trunk 29 through second diluent inlet 25, fluid communication between common trunk 29 and valve body 40g. Valve supply branch 27h provides, for a first diluent introduced to common trunk 127 through first diluent inlet 24, fluid communication between common trank 127 and valve body 40h, about which is implemented valve unit 39h, while valve supply branch 3Oh provides, for a second diluent introduced to common trunk 29 through second diluent inlet 25, fluid communication between common trunk 29 and valve body 40h, Valve supply branch 27i provides, for a first diluent introduced to common trunk 127 through first diluent inlet 24, fluid communication between common trunk 127 and valve body 40i, about which is implemented valve unit 39i, while valve supply branch 30i provides, for a second diluent introduced to common trunk 29 through second diluent inlet 25, fluid communication between common trunk 29 and valve body 40i. Valve supply branch 27j provides, for a first diluent introduced to common trunk 127 through first diluent inlet 24, fluid communication between common trunk 127 and valve body 40j, about which is implemented valve unit 39j, while valve supply branch 30j provides, for a second diluent introduced to common trunk 29 through second diluent inlet 25, fluid communication between common trunk 29 and valve body 40j. As shown in the figures, and as will be better understood further herein, it should at this point be noted that, for the exemplar / implementation of the present invention as now shown and described, each valve supply branch 27a-27j from the common trunk 127 of the first diluent inlet manifold 126, and each valve supply branch 30a-30j from the common trunk 29 of the second diluent inlet manifold 28, like the beverage product supply conduits 31a-31h, interface with its respective valve body 40a-40j at substantially the same vertical position from one valve body 40a-40j to another. Contrary’ to the case of the beverage product supply conduits 31a-31h, however, the radial position about a valve body 40a-40j at which each corresponding valve supply branch 27a-27j interfaces with the respective valve body 40a-40j are, for the exemplary implementation of the present invention as now7 shown and described, at an angular separation from the radial position about the valve body 40a-40j at which each corresponding valve supply branch 30a-30j interfaces that is substantially the same from one valve body 40a-40j to another. To this end, as most clearly depicted in Figure 15, each valve supply branch 27a-27j and each valve supply branch 30a-30j is shown to terminate at a uniform vertical location in the lower section of the valve bodies 40a-40j. Likewise and as most clearly depicted in Figure 17, the angular separation between the radial position at which each valve supply branch 27a-27j and the radial position at which the corresponding valve supply branch 30a-30j interface with a valve body’ 40a-40j is shown to be uniform from one valve body 40a-40j to another, although in at least some other implementations such uniformity need not exist. As also previously noted, each valve body’ 40a-40j is in fluid communication with the common diluents outlet 37 through a shared fluid conduit. As particularly shown in Figure 16, a common diluents outlet manifold 32 includes a common trunk 33 in fluid communication with the single, common diluents outlet 37. As shown in Figures 22-23, a plurality of valve dispense branches 34a-34j is formed, or otherwise provided, in fluid communication with, and feed diluent to, common trunk 33. As will be better understood further herein, there is provided one valve dispense branch 34a-34j for each implemented valve un it 39a-39j. Although other shapes or implementations are possible, the common trunk 33 and its corresponding valve dispense branches 34a-34j of the exemplary preferred implementation of the common diluents outlet manifold 32 comprise an arrangement of generally elongate tubular members routed, within the handle body 11, between the valve bodies 40a-40j and the common diluents outlet 37, as variously shown in combined Figures 1042, 1445 and 22-23. As shown in combined Figures 18A-18D and 22-23, valve dispense branch 34a provides, for a diluent released by valve unit 39a, fluid communication between valve body 40a, about which is implemented valve unit 39a, and common trunk 33, which in turn provides fluid communication of the diluent released from valve unit 39a to the single, common diluents outlet 37. Valve dispense branch 34b provides, for a diluent released by valve unit 39b, fluid communication between valve body 40b, about which is implemented valve unit 39b, and common trunk 33, which in turn provides fluid communication of the diluent released from valve emit 39b to the single, common diluents outlet 37. Valve dispense branch 34c provides, for a diluent released by valve unit 39c, fluid communication between valve body 40c, about which is implemented valve unit 39c, and common trunk 33, which in turn provides fluid communication of the diluent released from valve unit 39c to the single, common diluents outlet 37. Valve dispense branch 34d provides, for a diluent released by valve unit 39d, fluid communication between valve body 40d, about which is implemented valve unit 39d, and common trunk 33, which in turn provides fluid communication of the diluent released from valve unit 39d to the single, common diluents outlet 37. Valve dispense branch 34e provides, for a diluent released by valve unit 39e, fluid communication between valve body 40e, about which is implemented valve unit 39e, and common trunk 33, which in turn provides fluid communication of the diluent released from valve unit 39e to the single, common diluents outlet 37. Valve dispense branch 34f provides, for a diluent released by valve unit 39f, fluid communication between valve body 40f, about which is implemented valve unit 39f, and common trunk 33, which in turn provides fluid communication of the diluent released from valve unit 39f to the single, common diluents outlet 37. Valve dispense branch 34g provides, for a diluent released by valve unit 39g, fluid communication between valve body 40g, about which is implemented valve unit 39g, and common trunk 33, which in turn provides fluid communication of the diluent released from valve unit 39g to the single, common diluents outlet 37, Valve dispense branch 34h provides, for a diluent released by valve unit 39h, fluid communication between valve body 40h, about which is implemented valve unit 39h, and common trunk 33, which in turn provides fluid communication of the diluent released from valve unit 39h to the single, common diluents outlet 37, Valve dispense branch 34i provides, for a diluent released by valve unit 39i, fluid communication between valve body 40i, about which is implemented valve unit 39i, and common trunk 33, which in turn provides fluid communication of the diluent released from valve unit 39i to the single, common diluents outlet 37. Valve dispense branch 34j provides, for a diluent released by valve unit 39j, fluid communication between valve body 40j, about which is implemented valve unit 39j, and common trunk 33, which in turn provides fluid communication of the diluent released from valve unit 39j to the single, common diluents outlet 37. As shown in the figures, each valve dispense branch 34a-34j to the common trunk 33 of the diluents outlet manifold 32 --- like the beverage product supply conduits 31a-31h and the beverage product dispensing conduit 35a-35h - may interface with its respective valve body 40a-40j at any radial position about the respective valve body 40a-40j, the circumferential placement being largely a matter of accommodating each conduit within the veryr limited available space. On the other hand, however, and as will be better understood further herein, it should at this point be noted that each valve dispense branch 34a-34j - like the beverage product supply conduits 31a-31h, the beverage product dispensing conduits 35a-35h, and each valve supply branch 27a-27j and 30a-30j -interfaces with its respective valve body 40a-40j at substantially the same vertical position from one valve body 40a-40j to another. The vertical position for the valve dispense branches 34a-34j, however, is vertically separated from the previously discussed vertical position for the valve supply branches 27a-27j and 30a-30j. To this end, as most clearly depicted in Figure 15, the valve dispense branches 34a-34j are shown to originate at a uniform vertical location in the lower midsection of the valve bodies 40a-40j, which, as is shown in the figures, is a location vertically separate from the location at which the valve supply branches 27a-27j and 30a-30j terminate. As previously noted, the novel piping system 22 of the present invention enables an end-user to selectively establish various flow paths through the hand-held beverage dispenser 10 in order to select, on a beverage product-by-beverage product basis, one of a plurality of available diluents for dispensing from the hand-held beverage dispenser 10 with the beverage product. In particular, as will be better understood further herein, each provided valve unit 39a-39j inventively implements two distinct valves about a single valve body 40a-40j, whereby the no vel arrangement of the present invention is capable of realizing a flow control valve 54a-54j and a diluent selection valve 82a-82j for at least each beverage product to be dispensed by the hand-held beverage dispenser 10, all of which is implemented substantially within the extents of the handle body 11 of the hand-held beverage dispenser 10. For clarity, the term “substantially within the extents,” as used herein with reference to any handle body 11, 151 of the present inventions, whether in describing or claiming any aspect of the present inventions, shall be taken to mean that any feature so described or claimed is, in general, within the outer extents of the handle body, which includes any portion of the feature that also forms any aspect of the outer extents of the handle body. The term expressly excludes any aspect of the feature that protrudes into the beyond the normal grip of the handle body or interferes with control of the hand-held beverage dispenser 10, 150, but includes aspects that extend as necessary to form or interface with a control, or to form or interface with and inlet or outlet to or from the handle body, or is otherwise contained within a cover or the like as would be attached in use to the handle body. At this juncture it is also noted that when referring to various valves, whether in describing or claiming any of the present invention, the term “functionally independent” shall mean that each one of a plurality of valves may be actuated, operated or otherwise used in its normal function without regard to the state of any other such valve, and that actuation, operation or other use of any such valve shall not cause any change in state of any other such valve. Likewise, when referring to various valves, whether in describing or claiming any of the present invention, the term “distinct” shall mean that each one of a plurality of valves performs mutually exclusive function functions, e.g. a first valve turning a flow on or off and a second valve selecting a single source from many when neither valve is provided with the capability to perform the function of the other. In any case, in use of the present invention, as will be better understood further herein, the previously described fluid inlets 23 are conventionally placed in fluid communication with outlets from a flow control and manifold assembly or any other like source of at least one beverage product and a plurality of diluents, and the previously described fluid outlets 36 are placed in fluid communication with any suitable post-mix type drink dispenser assembly, as well known in the relevant arts. Additionally, as will be better understood further herein, the end-user will, for at least each of the provided beverage products, utilize a corresponding one of the inventively implemented diluent selection valves 82a-82j to select one of the plurality of diluents for dispensing with the corresponding beverage product. Referring now then to Figures 1-3, 16 and 18A-18D, and with the foregoing discussions of the flow paths through the piping system 22 of the exemplary implementation in mind, it is to be understood that with the hand-held beverage dispenser 10 deployed for operation as described, the end-user will depress, or otherwise operate, one of the flow controls 14a-14j to actuate the corresponding flow control valve 54a-54j, and dispense a desired beverage product with its selected diluent, or, as will be better understood further herein, a diluent alone. In particular, when an end-user operates now control 14a to actuate flow control valve 54a, beverage product admitted to the hand-held beverage dispenser 10 through beverage product inlet 26a flows through beverage product supply conduit 31a, and is allowed by the “ON” flow control valve 54a to pass through valve unit 39a into beverage product dispensing conduit 35a, whereafter the beverage product flows from beverage product outlet 38a into the provided post-mix type drink dispenser assembly 104. Simultaneously, the “ON” flow control valve 54a allows passage of the end-user selected diluent through the valve unit 39a. In particular, and depending on the end-user selected position of diluent selection valve 82a for the depicted exemplary embodiment, either the first diluent, as admitted through the first diluent inlet 24, wall flow through the common trunk 127 and valve supply branch 27a of the first diluent inlet manifold 126 and pass through the diluent selection valve 82a, or the second diluent, as admitted through the second diluent inlet 25, wall flow' through the common trunk 29 and valve supply branch 30a of the second diluent inlet manifold 28 and pass through the diluent selection valve 82a. In any case, the selected first or second diluent wall be passed from the “ON” flow control valve 54a, through the valve dispense branch 34a and common trunk 33 of the common diluents outlet manifold 32, whereafter the selected diluent flows from the single, common diluents outlet 37 into the provided post-mix type drink dispenser assembly 104 to mix, as is otherwise conventional, with the simultaneously dispensed beverage product. As shown in the figures, the foregoing manner of operation is identical for each additionally implemented beverage product inlet 26b-26h. When an end-user operates flow control 14b-14h to actuate corresponding flow control valve 54b-54h, beverage product admitted to the band-held beverage dispenser 10 through corresponding beverage product inlet 26b-26h flows through corresponding beverage product supply conduit 31b-31h, and is allowed by the corresponding “ON” flow control valve 54b-54h to pass through corresponding valve unit 39b-39h into corresponding beverage product dispensing conduit 35b-35h, whereafter the beverage product flows from corresponding beverage product outlet 38b-38h into the provided post-mix type drink dispenser assembly 104. Simultaneously, the corresponding “ON” flow control valve 54b-54h allows passage of the end-user selected diluent through the corresponding valve unit 39b-39h. In particular, and depending on the end-user selected position of corresponding diluent selection valve 82b-82h for the depicted exemplary embodiment, either the first diluent, as admitted through the first diluent inlet 24, will flow through the common trunk 127 and corresponding valve supply branch 27b-27h of the first diluent inlet manifold 126 and pass through the corresponding diluent selection valve 82b-82h, or the second diluent, as admitted through the second diluent inlet 25, will flow through the common trunk 29 and corresponding valve supply branch 30b-30h of the second diluent inlet manifold 28 and pass through the corresponding diluent selection valve 82b-82h. In any case, the selected first or second diluent will be passed from the corresponding “ON” flow control valve 54b-54h, through the corresponding valve dispense branch 34b-34h and common trunk 33 of the common diluents outlet manifold 32, whereafter the selected diluent flows from the single, common diluents outlet 37 into the provided post-mix type drink dispenser assembly 104 to mix, as is otherwise conventional, with the simultaneously dispense beverage product. As particularly shown in Figure 18D, ■with reference to Figure 16, the present invention also contemplates, and provides for, the selective dispensing from the hand-held beverage dispenser 10 of a diluent alone. As shown in the figure, adjunct valve units 39i and 39j are provided without corresponding beverage product supply conduits and beverage product dispensing conduits. As will be better understood further herein, no other change is necessary to implement this feature, and, as a result, no additional or different valve components are required. As will be appreciated by those of ordinary skill in the art, this not only greatly simplifies implementation of the present inventions, but saves manufacturing and maintenance costs as well as enhances usability. In any case, for each of valve units 39i-39j, as shown in the exemplary implementation, the end-user will utilize the corresponding diluent selection valves 82i-82j to select one of the plurality of diluents for dispensing with flow control 14i-14j, respectively. When an end-user operates one of flow controls 14i-14j to actuate either flow control valve 54i or flow control valve 54j, respectively, the “ON” flow control valve 54i or flow’ control valve 54j allows passage of the end-user selected diluent through the corresponding valve unit 39i-39i. In particular, and depending on the end-user selected position of corresponding diluent selection valve 82i-82j, either the first diluent, as admitted through the first diluent inlet 24, will flow through the common trunk 12.7 and corresponding valve supply branch 27i-27j of the first diluent inlet manifold 12.6 and pass through the corresponding diluent selection valve 82i-82j, or the second diluent, as admitted through the second diluent inlet 2.5, will flow7 through the common trunk 29 and corresponding valve supply branch 30i-30j of the second diluent inlet manifold 28 and pass through the diluent selection valve 82i-82j. In any case, the selected first or second diluent will be passed from the corresponding “ON” flow control valve 54i-54j, through the corresponding valve dispense branch 34i-34j and common trunk 33 of the common diluents outlet manifold 32, whereafter the selected diluent flows from the single, common diluents outlet 37 into the provided post-mix type drink dispenser assembly 104 to be dispensed. As previously noted, each provided valve unit 39a-39j inventively implements two distinct valves about a single valve body 40a-40j, such that a flow control valve 54a-54j and a diluent selection valve 82a-82j may be provided substantially within the handle body 11 of the hand-held beverage dispenser 10 for each beverage product to be dispensed. Referring then to Figures 24-32, the novel valve bodies 40a-40j - about which the inventive valve units 39a-39j of the exemplary preferred embodiment of the present invention are implemented -are described m detail with reference to a depicted representative valve body 40d. In an important aspect of the present invention, it is noted that at least the internal shapes and structures of each valve body 40a-40j, as well as any implemented ports or other openings in to or out of the interior spaces of the valve bodies 40a-40j, are preferably substantially identical from one valve body to another. The exterior shapes and other details, on the other hand, may vary widely within the scope of the present invention. That said, and as particularly shown in Figures 24-25, the representative valve body 40d, which, as will be better understood further herein, is generally tubular, is shown to comprise a cylindrical flow’ control valve stem orifice 42 at the top 41 of the valve body 40d and a larger circular open end 53 at the bottom 52 of the valve body 40d, each of which will be better understood further herein. As previously described, a number of tubular conduits generally provide fluid communication in to and out of each valve body 40a-4Qj. As shown in the figures, a beverage product supply conduit 3Id, a beverage product dispensing conduit 35d, a valve supply branch 27d from the common trunk 127 of the first diluent inlet manifold 126, a valve supply branch 30d from the common trunk 29 of the second diluent inlet manifold 28, and a valve dispense branch 34d to the common trunk 33 of the common diluents outlet manifold 32 all interface with the valve body 40d. In the exemplary' implementation of the present invention, each tubular conduit of a common type most preferably interfaces with its respective valve body 40a-40j at a vertical position that, for such type, is consistent from one valve body to another. To this end, and as particularly shown in Figures 26-29, the beverage product supply conduit 3 Id interfaces with the valve body 40d in horizontal plane Pl therethrough, the beverage product dispensing conduit 35d interfaces with the valve body 40d in horizontal plane P2 therethrough, the valve supply branch 27d from the common trunk 127 of the first diluent inlet manifold 126 and the valve supply branch 30d from the common trunk 29 of the second diluent inlet manifold 28 each interfaces with the valve body 40d in horizontal plane P3 therethrough, and the valve dispense branch 34d to the common trunk 33 of the common diluents outlet manifold 32 interfaces with the valve body 40d in horizontal plane P4 therethrough. As particularly shown in Figures 30-32 and 34, the interior space of the valve body 40d generally forms an upper cylindrical chamber 43 and a lower cylindrical chamber 48, wherein the diameter of the lower cylindrical chamber 48 is greater than the diameter of the upper cylindrical chamber 43 by a distance approximately twice the thickness of the cylindrical side wall 84 of an open topped cup 83 forming an integral part of the valves 54d and 82d of the valve unit 39d, as will be better understood further herein. As also shown in the figures, an upper groove 47 for receiving a flow control valve seal 75, as will be better understood further herein, is formed in the top 41 of the valve body 40d about the cylindrical flow control valve stem orifice 42. Likewise, a lower groove 51 for receiving a diluent selector valve seal 77, as wall be better understood further herein, is formed in the bottom 52 of the valve body 40d about the circular open end 53 formed therein. Finally, a plurality of valve ports is formed through the side w’alls of the valve body 40d to provide selective fluid communication to or from within the valve body 40d from or to without the valve body 40d. In particular, as shown in the figures, a beverage product inlet port 44 is formed at plane Pl through the upper midsection of the side wall of the valve body 40d and in alignment with beverage product supply conduit 3Id. Likewise, a beverage product outlet port 45 is formed at plane P2 through the side wall adjacent the upper end of the valve body 40d and in alignment with beverage product dispensing conduit 35d. Additionally, a first diluent inlet port 49 is formed at plane P3 through the lower section of the side wall of the valve body 40d and in alignment with valve supply branch 27d, and a second diluent inlet port 50 is also formed at plane P3, but in alignment with valve supply branch 30d. Still further, a diluent outlet port 46 is formed at plane P4 through the lower midsection of the side wall of the valve body 40d and in alignment with the valve dispense branch 34d. At this juncture, it should be well noted that, for any particular valve body, the first diluent inlet port 49 need not correspond exclusively to the first diluent inlet manifold 126 and, likewise, the second diluent inlet port 50 need not correspond exclusively to the second diluent inlet manifold 28. To be sure, the assignment for any given diluent inlet port will depend largely on the ability to accommodate each valve supply branch within the very limited available space about the valve bodies 40a-40j. As shown in Figures 33-34, each valve body 40a-40j, as provided within the handie-body 11 and supported along with the rest of the piping system 22 by the internal mesh 21, or otherwise, is populated with various valve components in implementation of the previously described valve units 39a-39j. In particular, a spool 55, as shown in detail in Figures 35-37, is provided in implementation, as a spool valve, of each flow control valve 54a-54j. Likewise, a specially formed open topped cup 83, as shown in detail in Figures 45-48, is provided in implementation, as a novel cylindrically formed gate valve, of each diluent selection valve 82a-82j. Additionally, however, it is noted that in the inventive implementation of the present invention, the interior face of the cylindrical side wall 84 of the each open topped cup 83 is cooperatively adapted with the lower cylindrical chamber 48 of each valve body 40a-40j to form a portion of the cylinder within which the spool 55 operates. In any case, these and other constituent components of the valve units 39a-39j are now described in detail in the following exemplary' process for constructing the valve units 39a-39j. As shown in Figures 35-37, each valve spool 55 generally comprises a generally cylindrical spool core 56 having positioned thereon an upper land 70, for controlling flow of beverage product, and a lower land 71, for controlling flow an end-user selected diluent. The spool core 56 and lands 70, 71 are sized, shaped and otherwise adapted to operate within the valve cylinder formed by the cooperative arrangement between the upper cylindrical chamber 43 of the valve bodies 40a-40j and the cylindrical side wall 84 of the open topped cup 83, as the cup 83 is operatively received in place within the lower cylindrical chamber 48 of the valve bodies 40a-40j. For operation of the spool 55, external threading 59 is formed about the top portion 57 of the spool core 56. As will be better understood further herein, the top portion 57 of the spool core 56 functions as a valve stem 58, and, as shown in Figure 33, the external threading 59 is adapted to be received within a threaded hole 81 provided through each button cap 80. Those of ordinary skill in the art will in light of this exemplary’ description recognize, however, that means other than the provision of threading may be used to attach the button caps 80 to their respective valve stem 58. In the depicted exemplary implementation, a first groove 61 is formed about the midsection 60 of the spool core 56 for dependently supporting the upper land 70, and comprises an upper ridge 62 and a lower ridge 64 adapted to secure the land 70 in place. In assembly of the spool 55, the upper land 70, which may comprise a rubber or like material disk with a central orifice therethrough, slides downward over the spool core 56 from the top portion 57 of the spool core 56, and over the upper ridge 62 into place within the first groove 61. To facilitate placement without damage of the upper land 70, a relief 63 is preferably formed about the top edge of the upper ridge 64. Similarly, a second groove 66 is formed about the bottom portion 65 of the spool core 56 for dependently supporting the lower land 71, and comprises an upper ridge 67 and a lower ridge 68 adapted to secure the land 71 in place. In assembly of the spool 55, the lower land 71, which like the upper land 70 may comprise a rubber or like material disk with a central orifice therethrough, slides upward over the spool core 56 from the bottom portion 65 of the spool core 56, and over the lower ridge 68 into place within the second groove 66. To facilitate placement without damage of the lower land 71, a relief 69 is preferably formed about the bottom edge of the lower ridge 68. Those of ordinary skill in the art will in light of this exemplary description recognize, however, that other manufacturing techniques, such as, for example, over-molding, may be utilized to implement the spool 55. As shown in Figures 38-39, population of the valve units 39a-39j as implemented in the exemplary' preferred embodiment begins with placement within the valve body 40d of an upper seal 75 and a lower seal 77. The upper seal 75, which may comprise a rubber or like material O-ring 76, is pressed through the valve stem hole 13 corresponding to the valve body 40d, and dependently received within the previously described upper groove 47 formed in the upper cylindrical chamber 43 of the valve body 40d, where the upper seal 75 will serve to prevent fluid leaks during operation in use of the valve stem 58. The lower seal 77, which may comprise a rubber or like material O-ring 78, is inserted through the cylindrical open end 53 of the valve body 40d and positioned in place within the previously described lower groove 51 formed in the lower cylindrical chamber 48 of the valve body 40d, where the lower seal 77 will serve to prevent fluid leaks during operation of the implemented diluent selection valve 82d, and will also serve to help hold in place the open topped cup 83 forming the diluent selection valve 82d. With the valve body 40d prepared as described, an assembled spool 55 is inserted through the cylindrical open end 53 of the valve body 40d, as shown in Figure 40, and a valve spring 79 is placed over the valve stem 58, as shown in Figure 41. A button 80, having a threaded hole 81 therethrough, is then fixed to the external threading 59 provided at the top portion 57 of the spool 55. The spring 79 and button 80 cooperate with the top surface 12 of the handle body 11 to secure the spool in place, as shown in Figures 42-43. The foregoing steps are then repeated for each remaining valve unit 40a-40c and 40e-40f, as also shown in Figures 42-43. With each valve body 40a-40j partially populated with a secured in place spool 55, as described, an open topped cup 83 is inserted through the circular open end 53 of each valve body 40a-40j to encompass the bottom portion 65, including the lower land 71, of the secured in place spool 55 as the cup 83 is fitted in place within the lower cylindrical chamber 48 of the valve body 40a-40j. As shown hi Figures 45-48, an exemplary implementation of the open topped cup 83, as suitable for forming the novel diluent selection valves 82a-82j according to the present invention, generally comprises a cylindrical side wall 84, which acts as valve gate having a first flow aperture 85 and a second now aperture 86 therethrough, and a closed bottom 89. A stop tab 88 is formed at a lower exterior portion 87 of the cup 83, and the bottom side 90 of the cup is provided with a blind slot 91 for engagement with a flat head screw' driver or a like instrument. As will be better understood further herein, each cup 83 is partially rotatable as received wdthin a valve body 40a-40j, and rotation in one direction will position the implemented diluent selection valve 82a-82j to enable flow' of the first diluent while blocking flow of the second diluent, and rotation in the opposite direction will position the implemented diluent selection valve 82a-82j to cause block of the first diluent while enabling flow of the second diluent. With an open topped cup 83 fitted in place within the lower cylindrical chamber 48 of each valve body 40a-40j and temporarily held in place bv the lower seal 77 provided within the valve body 40a-40j, as shown in Figure 49, a base plate 92 is secured about the cups 83 and bottoms 52 of the valve bodies 40a-40j. As shewn in Figures 50-51, the base plate 92 is in turn suitably seemed in place using conventional mounting hardware, such as, for example, screws 51 inserted through mounting holes 100 and received in threaded mounting bosses 128 formed in the handle body 11. While the removable base plate 92 provides access to the valve bodies 40a-40j for maintenance, and to the interior spaces of the handle body 11 as may from time-to-time be necessary' for cleaning, the base plate 92 also forms an integral part of the preferred implementation of the diluent selector valves 82a-82j. As previously noted, each provided cup 83 is only partially rotatable in place within the lower cylindrical chamber 48 of a valve body 40a-40j. To this end, and as also previously noted each cup 83 comprises a stop tab 88 at the lower exterior portion 87 of its cylindrical side wall 84. As shown in Figure 52, with reference to Figure 50 for perspective, the top side 93 of the base plate 92 is specially formed with a recess 94 corresponding to each valve body 40a-40j, and sized, shaped and otherwise adapted to conformingly receive the exterior lower portion 87, including the provided stop tab 88, of each cup 83 fitted within a valve body 40a-40j. As shown in the figures, each recess 94 has a circular arc portion 95 between a first stop 95 and a second stop 97. As the base plate 92 is affixed about the cups 83 to close the bottom 15 of the handle body 11, as shown in Figure 54, care must therefore be taken to ensure that each cup 83 is properly aligned with its corresponding recess 94 such that the stop tab 88 of the cup 83 lies between the first stop 96 and second stop 97 opposite the circular arc portion 95 such that the lower exterior portion 87 of the cup is fully received within the recess 94, as shown in Figures 55-56. It is now also noted that while the present invention could be implemented with the open topped cups 83 comprising only a single flow aperture through the cylindrical side wall 84, provision of a first flow' aperture 85 and a second flow aperture 86 enables a greatly decreased degree of rotation between the first stop 95 and the second stop 97, thereby facilitating placement of the cups 83 within the limited available space. Referring now' to Figures 57A-58B, the cooperative arrangement of the cups 83 and base plate 92 is described in greater detail. As shown in Figures 57A and 58A, when a cup 83 is properly seated with a recess 94 of the base plate 92, as shown in Figure 56, the blind slot 91 provided on the bottom side 90 of the cup 83 is accessible from the bottom side of the base plate 92 - that is, outside of the handle body 11 - through the diluent selection apertures 99 through the base plate 92. As depicted in Figure 57A, the blind slot 91 has been turned in the counterclockwise direction to the full rotational limit of the cup 83, as shown in Figure 57B by the contact of the stop tab 88 of the cup 83 against the first stop 96 in the recess 94 of the base plate 92. In this position, it is noted, the first flow aperture 85 through the cylindrical side wall 84 of the cup will be in alignment with the second diluent inlet port 50 of valve body 40d. As depicted in Figure 58A, the blind slot 91 has been turned in the clockwise direction to the full rotational limit of the cup 83, as shown in Figure 58B by the contact of the stop tab 88 of the cup 83 against the second stop 97 in the recess 94 of the base plate 92. In this position, it is noted, the second flow aperture 86 through the cylindrical side wall 84 of the cup will be in alignment with the first diluent inlet port 49 of valve body 40d. As also shown in Figures 57B and 58B, the conformance of the circular arc portion 95 of the recess 94 about the lower exterior portion 87 of the cup 83 serves to stabilize the axial alignment of the cup 83 and the diluent selection apertures 99. Referring now to Figures 59A-59E, 60A-60E, 61A-61E and 62A-62E, the four states of operation of the representative valve unit 39d are shown and described. In Figures 59A-59E, the diluent selection valve 82d is positioned to align the second flow aperture 86 through the cup 83 with the first diluent inlet port 49 of the valve body 40d, thereby selecting the first diluent for passage through valve supply branch 27d to the flow control valve 54d. The flow control 14d, however, is not actuated and, as a result, the upper land 70 of the flow control valve 54d blocks beverage product from beverage product supply conduit 3Id from passing into the valve body 40d while the lower land 71 blocks the first diluent from valve supply branch 27d from passing into the valve body 40d. In Figures 60A-60E, the diluent selection valve 82d is positioned to align the second flow aperture 86 through the cup 83 with the first diluent inlet port 49 of the valve body 40d, thereby selecting the first diluent for passage through valve supply branch 27d to the flow control valve 54d. Because the flow control 14d is actuated, the upper land 70 is moved downward within the valve body 40d to allow passage of beverage product from beverage product supply conduit 3 Id through the valve body 40d and into beverage product dispensing conduit 35d and the lower land is moved downward within the valve body 40d to allow passage of the first diluent from valve supply branch 27d through the valve body 40d and into valve dispense branch 34d leading to the common diluents trunk 33. In Figures 61A-61E, the diluent selection valve 82d is positioned to align the first flow aperture 85 through the cup 83 with the second diluent inlet port 50 of the valve body 40d, thereby selecting the second diluent for passage through valve supply branch 30d to the flow control valve 54d. The flow control 14d, however, is not actuated and, as a result, the upper land 70 of the flow control valve 54d blocks beverage product from beverage product supply conduit 3 Id from passing into the valve body 40d while the lower land 71 blocks the second diluent from valve supply branch 30d from passing into the valve body 40d. In Figures 62A-62E, the diluent selection valve 82d is positioned to align the first flow aperture 85 through the cup 83 with the second diluent inlet port 50 of the valve body 40d, thereby selecting the second diluent for passage through valve supply branch 30d to the flow control valve 54d. Because the flow control 14d is actuated, the upper land 70 is moved downward within the valve body 40d to allow passage of beverage product from beverage product supply conduit 3Id through the valve body 40d and into beverage product dispensing conduit 35d and the lower land is moved downward within the valve body 40d to allow passage of the second diluent from valve supply branch 30d through the valve body 40d and into valve dispense branch 34d leading to the common diluents trank 33, Finally, provision is made in the most preferred implementation of the hand-held beverage dispenser 10 of the present invention for the simple removal from the handle body 11 of the post-mix type drink dispenser assembly 104. As previously noted, this provision turns squarely away from the longstanding practice in the prior art of providing a post-mix type drink dispenser assembly that is either unitary with the handle body or so highly integral therewith as to make removal or disassembly for maintenance impractical if not wholly impossible, hi an effort to exceed the level of maintainability available in prior art dispensers, Applicant has developed post-mix type drink dispenser assembly 104 which is readily removable, as a module, from the handle body 11. In order to facilitate attachment of the inventive post-mix type drink dispenser assembly 104, however, Applicant has found it desirable to provide connector tubes 101, which, as particularly shown in Figures 63 and 66, are preferably press fit otherwise securely received in each of the fluid outlets 36 from the piping system 22 of exemplary preferred implementation of the hand-held beverage dispenser 10 of the present invention. It is noted, however, that while the provided connector tubes 101 are preferably securely attached to the fluid outlets 36, they are most preferably readily removably, but sealingly, received with corresponding connector tube orifices 108 provided in the implemented post-mix type drink dispenser assembly 104. In any case, the connector tubes 101, as provided consistent with the otherwise previously described exemplary implementation of the hand-held beverage dispenser 10 of the present invention, include a plurality of product pathways 102 and a diluents pathway 103. As previously noted the details of an exemplary post-mix type drink dispenser assembly, which operates in a manner consistent with the present invention for the provision of post-mix beverages, are shown and described in U.S. patent application Serial No. 16 / 394,889 filed April 25, 2019 for METHODS AND APPARATUS FOR POST-MIX DRINK DISPENSING, which has been incorporated herein. In at least the most preferred implementations of this aspect of the present invention, the multiple stage bodies of such a described dispenser assembly are press fit together or otherwise made umtary. and mounted within a preferably aesthetic mounting body 118. In this manner, the service industry employee that will typically care for the hand-held beverage dispenser 10 of the present invention will not be burdened with multiple parts that are easily lost or troublesome to assemble, while nonetheless making available the benefits of a removable nozzle assembly 104. In any case, the removable post-mix type drink dispenser assembly 104 includes a plurality of connector tube orifices 108 for receiving one each of the distal ends of the connector tubes 101. As shown in Figure 64, product tube orifices 109 are provided for each product pathway 102 and a diluents orifice 110 is provided for the diluents pathway. It should be noted, however, that in at least some implementations of the present invention the previously described connector tubes 101 may be provided integral or unitary with, and as a component of, the removable nozzle assembly 104, in which case the connector tubes 101 are readily removably, but sealingly received within, or otherwise attached in fluid communication with, the fluid outlets 36. Finally, as particularly shown in Figure 66, mounting boles 119 are provided through the aesthetic body 118, and conventional mounting hardware 120 such as, for example, screws 121 pass through the mounting boles 119 and secure within provided drink dispenser assembly mounting holes 19 provided on the handle body II. Referring now to Figures 67-71 in particular, a preferred implementation of a second embodiment, according to the present invention, of a hand-held beverage dispenser 150 of the bar gun class is shown to generally comprise a handle body 151, which, like the first embodiment, houses a novel piping system 158, sharing many characteristics described with respect to the first embodiment, and as shown in detail for the first embodiment in, for example, Figures 7-62, and a post-mix type drink dispenser assembly 104, which, as shown in the figures, is dependently coupled to the bottom 154 of the handle body 151 at a location adjacent the forward end 156 of the handle body 151. Like the previously described first embodiment, at least some preferred implementations of the second embodiment of the present invention contemplate the provision of a universal handle body 151 and piping system 158 suitable for use with any of a wide range of implementations for the post-mix type drink dispenser assembly 104. That said, the exemplary post-mix type drink dispenser assembly shown and described in U.S. patent application Serial No. 16 / 394,889 filed April 25, 2019 for METHODS AND APPARATUS FOR POST-MIX DRINK DISPENSING, which has bv prior reference been incorporated herein, operates in a manner consistent with, and is suitable for use in, the now described second embodiment of the hand-held beverage dispenser 150 of the present invention. The second embodiment of the hand-held beverage dispenser 150 of the present invention operates, like the first embodiment, to dispense a mixture of a desired beverage product and its corresponding appropriate diluent in a single-button, ON-OFF type operation, and therefore also does not include features for pressure regulation and the like. As a result the second embodiment of the hand-held beverage dispenser 150 of the present invention is supplied with fluids through any of many readily commercially available flow control assemblies. As is generally conventional in the art, the suitably selected assembly is connected to the hand-held beverage dispenser 150 through a multiplicity of individual fluid lines, through which the assembly will supply fluids at appropriately regulated pressures. The single-button, ON-OFF type operation implemented in the second embodiment of the hand-held beverage dispenser 150 is in keeping with Applicant’s desire that the present invention should substantially adhere to the simple operation expected by countless service industry employees worldwide. To this end, a plurality of ON-OFF flow controls 153a-153j is familiarly provided at the top 152 of the handle body 151 of the hand-held beverage dispenser 150. Additionally, the handle body 151 is most preferably ergonomically contoured about the sides 155 and bottom 154 to provide a secure, ambidextrous grip 178 for the end-user as the post-mix type drink dispenser assembly 104 is held steady over a beverage vessel while any of the ON-OFF flow controls 153a-153j is actuated (typically by thumb press), thereby increasing the comfort in hand and ease of use of the hand-held beverage dispenser 150. Also like the previously described first embodiment, the second embodiment of the hand-held beverage dispenser 150 of the present invention includes all basic handling and maintenance features typically expected by users. For example, and as particularly shown in Figures 70-71, a nozzle housing 122 for the mixer 105 (described in greater detail further herein) of the implemented exemplary post-mix type drink dispenser assembly 104 is readily removable to facilitate periodic cleaning of the post-mix type drink dispenser assembly 104. To this end, as show n in the figures, the upper portion 124 of the inner surface 123 of nozzle housing 122 is provided with a plurality of locking tabs 125 operably adapted to engage mating nozzle housing locking members 112 provided about a portion of the mixer 105. As shown in the figures, and as will be familiar to those of ordinary skill in the relevant arts as well as to sendee industry employees in general, the nozzle housing 122 locks in place with a partial twist about the mixer 105 in the clockwise direction, and is similarly released with a partial twist about the mixer 105 in the counterclockwise direction. Although, as noted above, Applicant has taken effort to ensure that the preferred implementation of the second embodiment of the hand-held beverage dispenser 150 of the present invention retains a familiar manner of operation, the second embodiment of the band-held beverage dispenser 150, like the previously described first embodiment, exceeds the level of maintainability of prior art dispensers. In particular, an alternative provision from that shown and described with respect to the first embodiment is made in the most preferred implementation of the second embodiment of the hand-beld beverage dispenser 150 of the present invention for the simple removal from the handle body 151 of the entire post-mix type drink dispenser assembly 104. As will be shown and described further herein, the implemented provision not only facilitates flexibility in the development of a commercial offering, but also provides enhanced product safety. Referring now to Figures 72-76, the novel piping system 158 of the present invention is shown to comprise various flow paths hosted substantially within the extents of the handle body 151 of the band-held beverage dispenser 150. For clarity at this juncture, Figures 72-76 depict only the handle body 151 and those components formed unitary with, or otherwise tightly integrated within the general extents of, the handle body 151. To this end, such components as aesthetic coverings, any particular interface to an external flow control assembly, the ON-OFF flow controls 153a-153j, the post-mix type drink dispenser assembly 104, and any other feature or component not fixed in place substantially within the extents of the handle body 151, as otherwise may appear in Figures 67-71 or elsewhere within this exemplary disclosure, are omitted from Figures 72-76. In any case, the novel piping system 158 of the second embodiment of the present invention, like the first embodiment, provides various How paths through the hand-held beverage dispenser 150 between a plurality of fluid inlets 159 to the piping system 158 and a plurality of fluid outlets 174 from the piping system 158, wherein at least some of the flow paths are selectively established. As will be better understood in the details set forth further herein, the novel piping system 158 of the present invention is adapted to enable, for each of a plurality of provided beverage products, end-user selection of any one of a plurality of provided diluents, whereafter the selected diluent is dispensed concurrently wdth the beverage product for which the selection has been made. As particularly shown in Figures 72-73, the plurality of fluid inlets 159 is provided at the rear end 157 of the handle body 151, and, for the depicted exemplary implementation, includes a first diluent inlet 160 and a second diluent inlet 161. Additionally, the plurality of fluid inlets 159 includes a plurality of beverage product inlets 162a-162h, there being provided one beverage product inlet 162a-162h for each of the number of beverage products that the implementation of the hand-held beverage dispenser 150 is capable of dispensing on demand. As discussed with respect to the first embodiment, however, the number of diluent inlets may be expanded to three or more, some aspects of the present invention apply to beverage systems utilizing only one diluent, and / or the implemented number of beverage product inlets may vary widely with such considerations as requirements of the intended commercial market, desired limits on the size or shape of the hand-held beverage dispenser 150, manufacturing cost, and the like. As also discussed with respect to the first embodiment, all such adjustments or modifications will, in light of this exemplary description, be readily within the ordinary skill in the relevant arts. In any case and as previously noted, the second embodiment of the hand-held beverage dispenser 150 of the present invention may be supplied with fluids through any of many readily commercially available flow control assemblies. In particular, individual fluid lines from a flow control assembly are typically collected within an elongate sheath tube, which, along with the fluid lines, terminates at a set of connectors sized, shaped and otherwise adapted to provide a fluid-tight interface between each fluid line a corresponding one of the fluid inlets 159 disposed at the rear end 157 of the handle body 151 of the hand-held beverage dispenser 150. As will be appreciated by those of ordinary skill in the relevant arts, the fluid inlets 159 are readily provided with any additional connector hardware as may be required to connect to the fluid lines from the flow' control assembly. As particularly shown in Figures 74-75, the previously mentioned plurality of fluid outlets 174 is provided at the bottom 154 and adjacent the forward end 156 of the handle body 151. Like the first embodiment of the hand-held beverage dispenser 10, the outlets 174 are placed and arranged to conduct dispensed fluids to the post-mix type drink dispenser assembly 104. For the depicted exemplary implementation of second embodiment of the hand-held beverage dispenser 150, the fluid outlets 174 include a single, common diluents outlet 175, and a plurality of beverage product outlets 176a-176h, there being provided one beverage product outlet 176a-176h for, and corresponding to, each one of the provided beverage product inlets 162a-162h. Also like the previously described first embodiment, the second embodiment of the hand-held beverage dispenser 150 of tire present invention is adapted to dispense a pressurized beverage fluid, as supplied at a suitable flow rate from a flow control assembly through one of the beverage product inlets 162a-162h, from a corresponding one of the beverage product outlets 176a-176h, and into the post-mix type drink dispenser assembly 104. Additionally, the second embodiment of the hand-held beverage dispenser 150 is adapted to concurrently dispense either a first pressurized diluent, as supplied at a suitable flow rate from the flow control assembly or other source through the first diluent inlet 160, or, in the alternative, a second pressurized diluent, as supplied at a suitable flow rate from the flow control assembly or other source through the second diluent inlet 161, from the single, common diluent outlet 175, and into the post-mix type drink dispenser assembly 104 where the end-user selected first or second diluent is mixed with the simultaneously dispensed beverage product. Although, as shown in Figures 74-75, the exemplary implementation of the second embodiment of the present invention comprises a single, common diluent outlet 175, a plurality of separate diluent outlets (for example, one for each diluent) may also be implemented within the scope of the present invention. As particularly shown in Figures 67 and 71, a set of ON-OFF flow controls 153a-153h is provided at the top 152 of the handle body 151 of the hand-held beverage dispenser 150, a single ON-OFF flow control 153a-153h being for and corresponding to beverage product introduced through one each of the provided beverage product inlet 162a-162h (shown in Figure 73) for dispensing from the also corresponding beverage product outlet 176a-176h (shown in Figure 75). Like the first embodiment, however, the most preferred implementation of the second embodiment of the hand-held beverage dispenser 150 of the present invention additionally includes a pair of ON-OFF flow controls 153i-l53j, each dedicated to dispensing a diluent only. What is more, in at least the most preferred implementations of the present invention, the provision of either the first or second diluent is also end-user selectable for each of ON-OFF flow controls 153i-153j. In any case, simply depressing an ON-OFF flow control 153a-153j will cause flow of either a beverage product and its corresponding selected diluent, or a diluent alone. At this point, it is again noted that the readily available flow control assemblies generally provide a capability for changing, on an ad hoc basis, the particular beverage product associated with a particular fluid line, and hence, m the case of the described exemplary implementation of the second embodiment of the hand-held beverage dispenser 150 of the present invention, supplied to the respective beverage product inlet 162a-162h. Although, as discussed with respect to the first embodiment, such changes may be carried out without affecting operation through any other fluid line of the dispenser, any particular change is subject to the ability of the newly supplied beverage product to be mixed with an appropriate diluent. Because, however, and as will be discussed in detail throughout this exemplary specification, the provision of either the first or second diluent is end-user selectable on a per beverage product inlet 162a-162h basis (equivalently described as on a per beverage product outlet 176a-176h basis), the correct diluent may readily be dispensed for any beverage product flowing through any beverage product inlet 162a-162h (beverage product outlet 176a-176h). What is more, and like the previously described first embodiment, the second embodiment of the hand-held beverage dispenser 150 also achieves the important advance over the prior art of enabling end-user selection of the first or second diluent without requiring disassembly of the hand-held beverage dispenser 150, depressurization of any flow path through the hand-held beverage dispenser 150 or its fluids-supplying flow control assembly, or any other disruption of the operation of the band-held beverage dispenser 150. As previously noted, the hand-held beverage dispenser 150 of the present invention includes a novel piping system 158, which is housed within the previously described handle body 151. Broadly described, the piping system 158 comprises a number of fluid conduits originating at various fluid inlets 159, as shown in Figures 72-73, or terminating at various fluid outlets 174, as shown in Figures 74-75. Additionally, however, the piping system 158 comprises a plurality of valve units 177a-177j, as schematically shown in Figures 77 and 78A-78D and described in greater detail further herein. As also will be described in greater detail further herein, each of the plurality of valve units 177a-177j is interposed between the fluid conduits from the fluid inlets 159 and the fluid conduits to the fluid outlets 174, as shown in Figures 77 and 78A-78D. Still further, each such valve unit 177a-177j is inventively implemented about a corresponding valve body 179a-179j, wherein a corresponding flow control valve 180a-180j and a corresponding diluent selection valve 181a-181j are integrally formed, as schematically shown in Figures 77 and 78A-78D and partially shown in place within the exemplary hand-held beverage dispenser 150 in Figures 74-76, and as will be described in greater detail further herein. Finally, and as will be better understood further herein, the implemented valve units 177a-177j together function to provide the previously mentioned novel end-user selective establishment of various flow paths through the hand-held beverage dispenser 150 of the presen t invention. At this juncture, it is again noted that when referring to various valves, whether in describing or claiming any of the present invention, the term “functionally independent" shall mean that each one of a plurality of valves may be actuated, operated or otherwise used in its normal function without regard to the state of any other such valve, and that actuation, operation or other use of any such valve shall not cause any change in state of any other such valve. Likewise, when referring to various valves, whether in describing or claiming any of the present invention, the term “distinct” shall mean that each one of a plurality of valves performs mutually exclusive function functions, e.g. a first valve turning a flow on or off and a second valve selecting a single source from many when neither valve is provided with the capability to perform the function of the other. To ensure clarity in the discussions to follow, it is at this juncture noted that in the exemplary’ implementation of the novel piping system 158 of the second embodiment of the hand-held beverage dispenser 150 of the present invention, as schematically’ shown in Figures 77 and 78A-78D and now described, beverage product inlet 162a is in fluid communication, through a correspondingly provided fluid conduit, with valve body 179a, and valve body 179a is in fluid communication, through a further correspondingly provided fluid conduit, with beverage product outlet 176a; beverage product inlet 162b is in fluid communication, through a correspondingly provided fluid conduit, with valve body 179b, and valve body 179b is in fluid communication, through a further correspondingly provided fluid conduit, with beverage product outlet 176b; beverage product inlet 162c is in fluid communication, through a correspondingly provided fluid conduit, with valve body 179c, and valve body 179c is in fluid communication, through a further correspondingly provided fluid conduit, with beverage product outlet 176c; beverage product inlet 162d is in fluid communication, through a correspondingly provided fluid conduit, with valve body 179d, arid valve body 179d is in fluid communication, through a further correspondingly provided fluid conduit, with beverage product outlet 176d; beverage product inlet 162e is in fluid communication, through a correspondingly provided fluid conduit, with valve body 179e, and valve body 179e is in fluid communication, through a further correspondingly provided fluid conduit, with beverage product outlet 176e; beverage product inlet 162f is in fluid communication, through a correspondingly provided fluid conduit, with valve body 179f, and valve body 179f is in fluid communication, through a further correspondingly provided fluid conduit, with beverage product outlet 176f; beverage product inlet 162g is in fluid communication, through a correspondingly provided fluid conduit, with valve body 179g, and valve body 179g is in fluid communication, through a further correspondingly provided fluid conduit, with beverage product outlet 176g; and beverage product inlet 162h is in fluid communication, through a correspondingly provided fluid conduit, with valve body 179h, and valve body 179h is in fluid communication, through a further correspondingly provided fluid conduit, with beverage product outlet 176h. Additionally, the first diluent inlet 160 is in fluid communication with each of the valve bodies 179a-179j through a corresponding shared fluid conduit, and the second diluent inlet 161 is in fluid communication with each of the valve bodies 179a-179j through a separate corresponding shared fluid conduit. Finally, each of the valve bodies 179a-179j is in fluid communication with the single, common diluents outlet 175 through yet another shared fluid conduit. To doubly ensure clarity in the discussions to follow, various details of the structure of a representative valve body 179d are shown, in various views, in Figures 79-87, as particularly implemented according to the teachings of the second embodiment of the hand-held beverage dispenser 150 of the present invention. In an important aspect of at least the most preferred embodiments of the present invention, it is noted that at least the internal shapes and structures of each valve body 179a-179j, and at least some aspects of any implemented ports or other openings into or out of the interior spaces of the valve bodies 179a-179j, may be and most preferably are, substantially identical from one valve body to another. The exterior shapes and other details, as well as some other aspects of any implemented ports or other openings into or out of the interior spaces of the valve bodies 179a-179j, however, may vary widely from one valve body to another. Any such divergence from the representative exemplary valve body 179d, as the valve body 179d is now or later described, will however be clearly noted in the discussions to follow. That said, it is reiterated that the representative arrangement of particular structures, openings and other details of valve body 179d is, like the whole of this present description, exemplary only, and other implementations within the scope of the present invention may require, prefer or allow for more or less consistency from one valve body to another. As best shown in Figures 79-87, the representative valve body 179d, according to the second preferred implementation of the hand-held beverage dispenser 150 of the present invention, generally comprises a tubular structure, having a stepped orifice running therethrough between the top 182 of the valve body 179d and the bottom 198 of the valve body 179d. As will be better understood further herein, a central axis 206 running top 182 to bottom 198 through the valve body 179d is defined by various cylindrical structures of the stepped orifice centered about the central axis 206. Additionally and as also will be better understood further herein, the central axis 206 establishes origin or central points of radial vectors, central arcs, and the like with or along which various features of exemplary valve unit 177d nm, are aligned, or are otherwise oriented. Unless indicated otherwise, reference to a central point, radial vector or the like of any structure of the valve body 179d, or any other component or structure thereof of the valve unit 177d, is to be understood as being with respect to the central axis 206, as the structure or component is operatively integrated into the valve unit 177d. In any case, and as particularly shown in combined Figures 79-81 and 85-87, the stepped orifice of the exemplary valve body 179d is formed or otherwise provided as a preferably cylindrical upper chamber 185, having a first internal diameter, atop an intermediate chamber 187 comprising a cylindrical interior wall 188 formed about central axis 206 and having a second internal diameter greater than the first internal diameter of the upper chamber 185, atop a lower chamber 192 comprising a cylindrical interior wall 193 formed about central axis 206 and having a third internal diameter greater than the second internal diameter of the cylindrical interior wall 188 of the intermediate chamber 187. Additionally, in any implementation of the upper chamber 185 in the preferred cylindrical interior shape, the cylindrical upper chamber 185 is also formed about central axis 206. As also shown in the figures, a plurality of valve ports is formed through the side walls of the valve body 179d to selectively provide fluid communication to or from within the valve body 179d from or to without the valve body 179d, according to the operational state of the valve unit 177d, as will be better understood further herein. To this end and as particularly shown in Figures 83-87 for the exemplary only implementation, a beverage product inlet port 189 is formed through the side wall of the valve body 179d and into the uppermost portion of the intermediate chamber 187, and a beverage product outlet port 186 is formed through the side wall of the valve body 179d and out of the upper chamber 185. Additionally, a first diluent inlet port 196 and a second diluent inlet port 197 are each formed through the side wall of the valve body 179d and into the uppermost portion of the lower chamber 192. Still further, a diluent outlet port 191 is formed through the side wall of the valve body 179d and out of the lower portion of the intermediate chamber 187. At this juncture, it should be well noted that, for any particular valve body, the first diluent inlet port 196 need not correspond exclusively to the first diluent inlet 160, and, likewise, the second diluent inlet port 197 need not correspond exclusively to the second dduent inlet 161. To be sure, the assignment for any given diluent inlet port wall depend largely on the ability' to accommodate the fluid conduits providing fluid communication between the first diluent inlet 160 and the second diluent inlet 161 and one each of the first diluent inlet port 196 and the second diluent inlet port 197 within the very limited available space about any particular one of the valve bodies 179a-179j, as will be better understood further herein. As previously noted, the novel piping system 158 of the present invention enables an end-user to selectively establish various flow’ paths through the hand-held beverage dispenser 150 in order to select, on a beverage product-by-beverage product basis, one of a plurality' of available diluents for dispensing from the hand-held beverage dispenser 150 with the beverage product. In particular, as will be better understood further herein, each provided valve unit 177a-177j inventively implements two distinct valves about a single valve body 179a-179j, whereby the novel arrangement of the present invention is capable of realizing a flow control valve 180a-180j and a diluent selection valve 181a-181j for at least each beverage product to be dispensed by the hand-held beverage dispenser 150. Additionally, for every beverage product to be dispensed, a flow control valve 180a-180j and a diluent selection valve 181a-18lj, implemented in accordance with the teachings of the present invention, may be provided substantially within the handle body 151 of the hand-held beverage dispenser 150. Accordingly, many details of the exemplary' preferred implementation of the representative valve body 179d are directed toward accommodating or otherwise forming the novel structures of the diluent selection valves 181 a-18Ij and the flo w control valves 180a-180j, as particularly implemented within the limited area available. Referring still to Figures 79-87, a number of features of the representative valve body 179d are shown as most preferably provided for integral use in the preferred implementations of the diluent selection valve 181d and the flow control valve 180d, in accordance with the second preferred implementation of the hand-held beverage dispenser 150 of the present invention, and as each will be better understood further herein. Those of ordinary skill in the relevant arts will, in light of this exemplary description, recognize possible variations to the described features. Thai said, it is noted that each of the structures, as now and further herein described, is most preferably implemented, provided, arranged and otherwise adapted and optimized to facilitate precise and reliable operation of each valve unit 177a-177j, while also contributing to the necessarily efficient use of available space, all of which will be better understood further herein. Beginning with features that will be better understood further herein as being particularly directed toward implementation of the previously identified diluent selection valve 18Id, it is first noted that, as previously described, the lower chamber 192 of the implemented stepped orifice comprises a cylindrical interior wall 193 formed about central axis 206 and having a greatest internal diameter of any chamber of the valve body 179d forming a part of the stepped orifice. As particularly shown in Figures 80 and 82-84, the valve body 179d also comprises a circular open end 199, which is located at the bottom 198 of the valve body 179d and opens into the lowermost portion of the lower chamber 192. As will be better understood further herein, the provided circular open end 199 is of a size commensurate with the third, and largest, internal diameter of the stepped orifice as established by the cylindrical interior wall 193 of the lower chamber 192. Like the cylindrical interior wail 193 of the lower chamber 192, the circular open end 199 at the bottom 198 of the valve body 179d is also concentric about the central axis 206, and thus in alignment with the cylindrical interior wall 193 of the lower chamber 192. As will be described in greater detail further herein, the open end 199 at the bottom 198 of the valve body 179d provides access to the interior of the valve body 179d for insertion to the valve body 179d of substantially the entire valve trim of the valve unit 177d. Additionally, however, the provided circular open end 199, along with the lower chamber 192, is adapted to not only receive valve trim in the assembly of the valve unit 177d, but also provides access to an open topped cup 207, which will be described in greater detail further herein as a key component of the diluent selection valve 181d, for user manipulation of the open topped cup 207 in operation of the diluent selection valve 181d. As will also be better understood further herein, it is through the provision of the circular open end 199 that at least a stop tab 217 forming an important aspect of the open topped cup 207 remains operably without the valve body 179d, where in cooperation with other components of the hand-held beverage dispenser 150 of the present invention the stop tab 217 forms an element of a poka-yoke mechanism delivering fundamental functionality of the diluent selection valve 181d. For employment in connection with the stop tab 217 formed or otherwise provided as part of the open topped cup 207, a notch 201 is formed in the circular open end 199 at the bottom 198 of the valve body 179d, as particularly shown in Figures 79-80, 83-84 and 86-87. As shown in the figures, the notch 201 intersects the portion of the cylindrical interior wall 193 of the lower chamber 192 at the bottom 198 of the valve body 179d to define a first stop 202 and a second stop 24 unitary' with the valve body 179d. As also shown in the figures, the first stop 202 comprises a preferably planar edge 203 most preferably lying in a vertical plane intersecting the central axis 206. Likewise, the figures also show the second stop 204 comprising a preferably planar edge 205 as most preferably implemented to lie within a vertical plane also intersecting the central axis 206. Implemented as preferred, the edge 203 of the first stop 202 and the edge 205 of the second stop 204 are radially disposed in an arc about the circular open end 199 at the bottom 198 of the valve body 179d. Accordingly, the measure of the disposing arc is characterized by the central angle of the previously defined central axis 206 that is congruent with the arc - that is, the central angle of the central axis 206 that intercepts the endpoints of the arc of the notch 201 at the edge 203 of the first stop 202 and the edge 205 of the second stop 204, and, which hereinafter is referred to as the congruent central angle of the notch 201. Also in furtherance of the preferred implementation of the diluent selection valve 181 d of the exemplary valve unit 177d of the second embodiment of the hand-held beverage dispenser 150 of the present invention, the valve body 179d comprises a shoulder 194 about the cylindrical interior wall 192 at the top of the lower chamber 192, and projecting inwardly from the cylindrical interior wall 192 in the direction of the central axis 206. As will be better understood further herein, the provided shoulder 194 is adapted to retain the previously introduced open topped cup 207 operatively in place substantially within the lower chamber 192, and more particular!}' to provide an upper barrier against which an upper edge 211 of a cylindrical side wall 208 of the open topped cup 207 abuts. In this manner, the shoulder 194 bard limits insertion into the valve body 179d of the open topped cup 207, as will be more particularly shown further herein. Additionally, it is noted that the open topped cup 207 will from time-to-time in use of the present invention rotate about the central axis 206 while operatively in place within the lower chamber 192. To this end, the shoulder 194 about the cylindrical interior wall 192 at the top of the lower chamber 192 most preferably comprises a downwardly facing, horizontally oriented planar surface lying within a plane transverse to the central axis 206 through the valve body 179d. As previously introduced, a plurality of valve ports is formed through the side walls of the valve body 179d to selectively provide fluid communication to or from within the valve body 179d from or to without the valve body 179d. As particularly pertain to the preferred implementation of the diluent selection valve 181d of the exemplary valve unit 177d, and as shown in Figures 83-87, a first diluent inlet port 196 and a second diluent inlet port 197 are each formed through the side wall of the valve body 179d and into the uppermost portion of the lower chamber 192. As also shown in the figures, and as will be better understood further herein, the fluid conduits of the piping system 158 of the second preferred implementation of the hand-held beverage dispenser 150 of the present invention include a valve supply branch 165d that is connected to, formed integral or unitary with, or otherwise interfaces to the first diluent inlet port 196 of valve body 179d for supplying a first diluent to valve unit 177d, as sourced from additional upstream fluid conduits of the piping system 158 described in detail further herein. Likewise, the fluid conduits of the piping system 158 include a valve supply branch 168d that is connected to, formed integral or unitary with, or otherwise interfaces to the second diluent inlet port 197 of valve body 179d for supplying a second diluent to valve unit 177d, as also sourced from additional upstream fluid conduits of the piping system 158 and also described in detail further herein. Additionally and as best shown in Figures 85-87, a single diluent outlet port 191 is formed through the side wall of the valve body 179d and out of the lower portion of the intermediate chamber 187. As also shown in the figures, and as will be better understood further herein, the fluid conduits of the piping system 158 of the second preferred implementation of the hand-held beverage dispenser 150 of the present invention include a valve dispense branch 172d that is connected to, formed integral or unitary with, or otherwise interfaces to the diluent outlet port 191 of valve body 179d. ’The valve dispense branch 172d, as interfaced with the diluent outlet port 191 of valve body 179d, conducts either the first diluent or the second diluent from valve unit 177d and through additional downstream fluid conduits of the piping system 158 to be dispensed from the hand-held beverage dispenser 150, as described in detail further herein. The first diluent or the second diluent, as supplied to the valve unit 177d through a corresponding one of either first diluent inlet port 196 or the second diluent inlet port 197, is selected for conduct through the diluent outlet port 191 of valve body 179d according to the operative state of the diluent selection valve 181d of the exemplary valve unit 177d, as will be better understood further herein. Although a complete understanding of the features provided by the valve body 179d in implementation of the diluent selection valve 181d can only be had with the further discussions to follow as are particularly directed to the provision and use of the diluent selection valve 18Id, the discussion to follow are aided by now noting some of the more important constraints placed on the valve body 179d by the particular implementation of the diluent selection valve 181d devised for realization of the valve unit 177d. For example, the specific implementation of the diluent selection valve 181d, as presented in this exemplary description, requires: (1) that the first diluent inlet port 196 and the second diluent inlet port 197 be arranged at the same vertical position about the valve body 179d; and (2) that the second diluent inlet port 197 be formed through the side wall of the valve body 179d at a suitable location at an established arc length about the side wall of the valve body 179d apart from a suitable location at which the first diluent inlet port 196 is formed through the side wall of the valve body 179d. In meeting the first of the forgoing requirements, the first diluent inlet port 196 and the second diluent inlet port 197 are each formed at a location about the side wall of the valve body 179d intersecting horizontal plane P23, as is shown in Figures 85-87. As to the second of the requirements, it is noted that in locating the first diluent inlet port 196 and the second diluent inlet port 197 at separate positions, each of which intersects plane P23, about the side wall of the valve body 179d, the first diluent inlet port 196 and the second diluent inlet port 197 are radially disposed in an arc about the side wall of the valve body 179d. Accordingly, the measure of the disposing arc is characterized by the central angle of the previously defined central axis 206 that is congruent with the arc - that is, the central angle of the central axis 206 that intercepts the endpoints of the arc of the side wall of the valve body 179d at the location of the first diluent inlet port 196 and the location of the second diluent inlet port 197, and which hereinafter is referred to as the congruent central angle of the diluent inlet ports 196, 197. It is noted that the foregoing discussion additionally requires that the first diluent inlet port 196 and the second diluent inlet port 197 be placed at “suitable” locations. As previously noted, the piping system 158 of the second embodiment of the hand-held beverage dispenser 150 of the present invention is be implemented substantially within the extents of the handle body 151 of the band-held beverage dispenser 150, as will also be discussed in more detail further herein. This constraint, which is similarly shared by all of the previously described valve ports formed through the side walls of the valve body 179d, necessitates that a suitable pair of locations about the side wall of the valve body 179d that each also intersect plane P23 must also accommodate routing each of the valve supply branch 165d interfacing with the first diluent inlet port 196 and the valve supply branch 168d interfacing with the second diluent inlet port 197 away from the valve body 179d and into fluid communication with respective other fluid conduits of the piping system 158, all substantially within the extents of the handle body 151 of the hand-held beverage dispenser 150. Still further, however, it is important to note carefully that establishment of the congruent central angle of the diluent inlet ports 196, 197, the location of the ports 196, 197 already being burdened with the forgoing constraints, will have a rippie effect constraining, or even largely defining, the implementation of many aspects of the present invention, as will be better understood in the discussions to follow. That said, the full import of the value established or otherwise determined for the congruent central angle of the diluent inlet ports 196, 197, should be fully appreciated prior to locating the first diluent inlet port 196 and the second diluent inlet port 197. To be sure, other constraints on affected components of the hand-held beverage dispenser 150 of the present invention are very likely to ripple back to in fact impose even further constraints on what constitute “suitable” locations for the first diluent inlet port 196 and the second diluent inlet port 197. Transitioning now from those features of the valve body 179d particularly directed toward implementation of the diluent selection valve 181 d to examine features of the valve body 179d that will be better understood further herein as being particularly directed toward implementation of the previously identified flow control valve 180d of the exemplary' valve unit 177d, but remaining focused primarily on various of Figures 79-87, attention is drawn once again to the previously described stepped orifice through the valve body 179d. First, however, it is noted that in the most general terms the flow control valve 180d is implemented in a novel valve structure comprising what may be considered a linked set of poppet-type valves. With this, it is further noted that the transition, or step, between the cylindrical upper chamber 185 of the valve body 179d and the intermediate chamber 187 of the valve body 179d implements an upper valve seat 190 for the flow control valve 180d, and the transition between the intermediate chamber 187 of the valve body 179d and the lower chamber 192 of the valve body 179d implements a lower valve seat 195 for the flow control valve iSod Isolation between fluid flows of an upper one of the poppet-type valves and fluid flows of a lower one of the poppet-type valves is effected within the intermediate chamber 187 of the valve body 179d all the while the intermediate chamber 187 additionally accommodates operable linkage of the linked set of poppet-type valves. In accordance with the now described exemplary valve unit 177d, the cylindrical interior wall 188 of the intermediate chamber 187 of the valve body 179d is therefore sized, shaped and otherwise adapted to operably support implementation within the intermediate chamber 187 of a customized reciprocating wiper seal. Still further, the intermediate chamber 187 together with the upper chamber 185 and the lower chamber 192 of the valve body 179d concurrently form the base structure for, and must each generally be sized, shaped and otherwise adapted to accommodate, the diverse complement of components and features that constitute the valve trim of the valve unit 177d. In accordance with the present invention, the inventive valve unit 177d, as illustrated through this present detailed description, balances or otherwise resolves any conflicting requirement or other tension between the components in order to provide the described highly optimized novel valve unit 177d at the core of the piping system 158 of the second embodiment of the hand-held beverage dispenser 150 of the present invention. As particularly shown in Figures 79 and 85-87, a flow control valve actuator orifice 183 is provided at the top 182 of the valve body 179d, and, as will be better understood further herein, must accommodate leak-proof reciprocation therethrough of a portion 229 of a cylindrical valve rod 228. To this end, the valve body 179d comprises an annulus 184 about the as implemented cylindrical flow control valve actuator orifice 183, and projecting inwardly from the flow control valve actuator orifice 183 in the direction of the central axis 206. As most particularly shown in Figures 85-87, the annulus 184 slightly reduces the diameter of the flow control valve actuator orifice 183, which is generally coextensive with the upper chamber of the valve body 179d, in order to dependently receive and retain in place an upper seal 259 for the flow control valve 180d of the valve unit 177d. As a result, the provided annulus 184 must be sized, shaped and otherwise adapted to accommodate the upper seal 259, the implementation and lull functionality of which will be detailed further herein. As previously noted, the transition between the upper chamber 185 of the valve body 179d and the intermediate chamber 187 of the valve body 179d implements an upper valve seat 190 for the flow control valve 180d, and the transition between the intermediate chamber 187 of the valve body 179d and the lower chamber 192 of the valve body 179d implements a lower valve seat 195 for the flow control valve 180d. In accordance with the preferred implementation of the valve body 179d of the second embodiment of the present invention, the upper chamber 185 is cylindrical about the central axis 206 of the valve body 179d. As a result, the upper valve seat 190 for the flow control valve 180d is readily formed within the valve body 179d as a chamfer, or other profile operatively shaped for sealing engagement by the corresponding structure of the flow control valve 180d, between the cylindrical interior wall 188 of the intermediate chamber 187 and the cylindrical upper chamber 185. As previously discussed, the lower chamber 192 of the valve body 179d operably receives therein the open topped cup 207, as forms a key component of the diluent selection valve 181d of the valve unit 177d. As also previously discussed the shoulder 194 about the cylindrical interior wall 192 at the top of the lower chamber 192 retains the open topped cup 207 operatively in place substantially within the lower chamber 192, and for purposes of the diluent selection valve 181d the shoulder 194 is most preferably formed as a horizontally oriented surface contained within a plane transverse to the central axis 206 through the valve body 179d. In addition to its functionality with respect to the diluent selection valve 181d, however, in the innovative valve unit 177d of the present invention the open topped cup 207 is also integral to the implementation of the flow control valve 180d. In particular, various aspects of an interior space 213 of the open topped cup 207, defined in part by a cylindrical interior surface 210 of the previously noted cylindrical side wall 208 of the open topped cup 207, interoperate with various aspects of a flow control valve trim assembly 227 of the flow control valve 180d to implement the flow control valve 180d of the valve unit 177d. To simultaneously accommodate implementation of both the diluent selection valve 181d and the flow control valve 180d, as will be better understood further herein, the inside edge 200 of the shoulder 194 at the top of the lower chamber 192, and within the transition between the intermediate chamber 187 of the valve body 179d and the lower chamber 192 of the valve body 179d, must have a diameter about the central axis 206 that is (1) less than the third internal diameter of the cylindrical interior wall 193 of the lower chamber 192 by at least the twice the sum of the radial thickness of the cylindrical side wall 208 of the open topped cup 207 and any gap space to be provided between the cylindrical side wall 208 of the open topped cup 207 and the cylindrical interior wall 193 of the lower chamber 192, and (2) greater than the second internal diameter of the cylindrical interior wall 188 of the intermediate chamber 187. Preferably, however, the diameter about the cental axis 206 of the inside edge 200 of the shoulder 194 will be approximately equal to or slightly less than the diameter about the central axis 206 of the cylindrical interior surface 210 of the cylindrical side wall 208 of the open topped cup 207, as the open topped cup 207 is operatively assembled within the valve body 179d in formation of the valve unit 177d. With the constraints of the shoulder 194 at the top of the lower chamber 192 of the valve body 179d met, the lower valve seat 195 for the flow control valve 180d is readily formed within the valve body 179d as a bevel, or other profile conforming to the corresponding structure of the flow control valve 180d, between the inside edge 200 of the shoulder 194 formed within the lower chamber 192 of the valve body 179d and the cylindrical interior wall 188 of the intermediate chamber 187 of the valve body 179d, It is now recalled that in discussing features of the representative valve body 179d particularly directed toward at least the specific implementation diluent selection valve 18Id as presented in this exemplary' description, a number of constraints were identified specifically for provision of the first diluent inlet port 196 and the second diluent inlet port 197, and also more generally for each of the previously described valve ports formed through the side walls of the valve body 179d. In particular, it was determined that for at least the specific implementation of the diluent selection valve 18Id, as herein described, the first diluent inlet port 196 and the second diluent inlet port 197 must each be formed at a respective location about the side wall of the valve body 179d intersecting the horizontal plane P23, as shown in Figures 85-87. Additionally, it was determined that the first diluent inlet port 196 and the second diluent inlet port 197 must be disposed in an arc about the side wall of the valve body 179d, and radially separated one from the other by a value designated as the central angle of the diluent inlet ports 196, 197. The central angle of the diluent inlet ports 196, 197 is established on careful consideration of the necessary interoperability between the first diluent inlet port 196 and the second diluent inlet port 197, as located one to the other, and numerous other components of or related to the valve unit 177d, the implementations of which will be understood further herein to depend or otherwise be affected by the established value of the central angle of the diluent inlet ports 196. 197. Finally, it was determined in considering the general requirement of “suitable” locations, that each of the previously described valve ports formed through the side wails of the valve body 179d must be located so as to accommodate routing substantially within the extents of the handle body 151 of the hand-held beverage dispenser 150 of every fluid conduit interfacing with any of the valve ports, and any fluid conduit between an interfacing conduit and either a fluid inlet 159 or a fluid outlet 174 to or from the handle 151. As will be recognized by those of ordinary skill in the relevant arts in light of this exemplary description, this final constraint on the features of the exemplary valve body 179d is applicable as much for integral use of the flow control valve 180d as it is for integral use of the diluent selection valve 181d. Each of the foregoing constraints on formation through the side walls of the valve body 179d of the previously identified valve ports remains, of course, unaffected by any constraint imposed for effective integral use of the flow control valve 180d, each of which is in addition to the previously identified constraints. That said, it is now noted that beyond the general constraint for accommodating routing of the elements of piping system 158 substantially within the extents of the handle body 151 of the hand-held beverage dispenser 150, and the constraint on the relative vertical locations the first diluent inlet port 196 and the second diluent inlet port 197 within horizontal plane P23, none of the thus far identified constraints place any restriction on the absolute vertical location of any of the previously described valve ports formed through the side walls of the valve body 179d, the absolute vertical positions of each of which are, with respect to the exemplary' valve body 179d, identified horizontal planes P21-P24. Additionally, beyond the general constraint for accommodating routing of the elements of piping system 158 substantially within the extents of the handle body 151 of the hand-held beverage dispenser 150, the constraint on the relative vertical locations the first diluent inlet port 196 and the second diluent inlet port 197 within horizontal plane P23, and the requirement to establish a particular radial separation between the first diluent inlet port 196 and the second diluent inlet port 197, none of the thus far identified constraints places any restriction on the absolute radial location about the valve body 179d of any of the previously described valve ports formed through the side walls of the valve body 179d. Referring still to Figures 85-87, it is noted that the detailed descriptions to follow of the diluent selection valve 181 d and the flow control valve 180, and more particularly of the integration of the diluent selection valve 181d and the flow control valve 180 within the valve body 179d, will reveal that an upper one of the linked set of poppet-type valves, as inventively implemented in the flow control valve 180, will in operation generally reciprocate within the intermediate chamber 187 of the valve body 179d in the space between the upper valve seat 190 formed at the transition between the cylindrical upper chamber 185 and the intermediate chamber 187 of the valve body 179d and the midsection of the intermediate chamber 187 above the diluent outlet port 191 of valve body 179d. Similarly, the foregoing detailed descriptions to follow will reveal that a lower one of the linked set of poppet-type valves, as inventively implemented in the flow control valve 180, will in operation generally reciprocate within the previous!}' introduced interior space 213 of the open topped cup 207, as the open topped cup 207 is operatively assembled lower chamber 192 of the valve body 179d, between the lower valve seat 195 formed at the transition between the intermediate chamber 187 of the valve body 179d and the lower chamber 192 of the valve body 179d and the bottom 214 of the interior space 213 of the open topped cup 207. Additionally and in an important aspect of the present invention, the detailed descriptions to follow will make clear that the most advantageous integration of the flow control valve 180 within the valve body 179d is obtained by locating the beverage product inlet port 189 through the side wall of the valve body 179d at the uppermost portion of the intermediate chamber 187 and as near as otherwise practicable to the upper the upper valve seat 190, which location is identified as horizontal plane P21, while also locating each of the first diluent inlet port 196 and the second diluent inlet port 197 through the side wall of the valve body 179d at the uppermost portion of the lower chamber 192 and as near as otherwise practicable to the lower valve seat 195, which location is identified as horizontal plane P23. Still further and as previously noted, the upper seal 259 for the flow control valve 180d is dependently received and retained in place within the flow control valve actuator orifice 183, but also extends a distance into the upper chamber 185 of the valve body 179d, as will be made clear in the discussions to follow. Accounting then for the placement of the first diluent inlet port 196, the second diluent inlet port 197 and the beverage product inlet port 189, and the resultant direction of the respective fluid Hows through the valve body 179d; providing operating clearance for the reciprocating elements of the How control valve 180; avoiding obstruction by the upper seal 259; and considering the general constraints on all valve ports formed through the side w'alls of the valve body 179d, the beverage product outlet port 186 is located through the side wall of the valve body 179d at the midsection of the upper chamber 185 of the valve body 179d, which location is identified as horizontal plane P22, and the diluent outlet port 191 is formed through the side wall of the valve body 179d at the lower portion of the intermediate chamber 187, which location is identified as horizontal plane P24. In summary, the constraints placed on the locations about valve body 179d for placement of the valve ports formed through the side walls of the valve body 179d are, in particular, that: (1) the beverage product inlet port 189 must be vertically located at horizontal plane P21; (2) the beverage product outlet port 186 must be vertically located at horizontal plane P22; (3) the first diluent inlet port 196 and the second diluent inlet port 197 must (a) each be vertically located at horizontal plane P23, and (b) be radially separated one from another by a fixed angle compatible with other elements of the implemented diluent selection valve 181 d; and (4) the diluent outlet port 191 must be vertically located at horizontal plane P24. Additionally, the constraints placed on the locations about valve body 179d for placement of the valve ports formed through the side walls of the valve body 179d include, in general, that all of the foregoing valve ports must be formed through the side walls of the valve body 179d at locations about valve body 179d that, for each particular valve port, enables routing any interfacing fluid conduit away from the valve body 179d, while maintaining also the fluid conduit substantially within the extents of the handle body 151 of the hand-held beverage dispenser 150, To be clear these constraints are as derived from Applicant’s consideration and balancing of the relative advantages or disadvantages of various design choices, as pertain particularly to Applicant’s preferred implementation of the other components of the novel piping system 158 of the second embodiment of the present invention. Consideration of the other components of the novel piping system 158, in reaching the constraints set forth, include consideration of the diluent selection valve 18Id and the flow control valve 180d as each are integrated with the valve body 179d in formation of the innovative valve unit 177d as all are realized according to Applicant’s preferred implementation of the second embodiment of the hand-held beverage dispenser 150 of the present invention. Additionally, however, and as will better understood in light of discussions to follow of relevant considerations, other factors such as, for example, mass, dimensions of user-interfacing components, material of construction and the like also at least influence the identified constraints. It is noted that each of the foregoing vertical constraints - a constraint confining a valve port to a location about a particular horizontal, or transverse, plane through the valve body 179d - derives, to at least some extent, from the need to operatively align with “inlet” and “outlet” portions of the implemented diluent selection valve 1 Bld and flow control valve 180d, and some vertical constraints are more tolerant to variance than others. For example and as will be better understood further herein, the constraint of the location of the beverage product outlet port 186 to horizontal plane P22 and the constraint of the location of the diluent outlet port 191 to horizontal plane P24 derive from a common need to breach the valve body 179d at a location within the corresponding valve chamber that is clear of any reciprocating components of the valve trim, and may have greater tolerances than do other constraints. On the other hand, the constraint of the location of the beverage product inlet port 189 to horizontal plane P21 and the constraint of the locations of the first diluent inlet port 196 and the second diluent inlet port 197 to horizontal plane P23 derive from a common need to breach the valve body 179d at a location within the corresponding valve chamber that is in alignment with or adjacent to a valve gate and / or a poppet disk, and may have only moderate tolerances as compared to other constraints. Still further, the constraint of the locations of the first diluent inlet port 196 and the second diluent inlet port 197 to any otherwise suitable set of locations that are radially separated one from another by a fixed angle derives from a need for operable compatibility with other components themselves constrained by necessary or desired optimizations and the like, and may require implementation within very limited tolerances as compared to other constraints. It is clear that some variance in implementation may be had as a simple matter of tolerances. Additionally, however, it is noted that much greater variation from the configuration depicted for the exemplary valve body 179d may be implemented with no change in the to be described valve trim of the valve unit 177d or several features external io the valve unit 177d that will be understood further herein to directly interface with the valve unit 177d, and nonetheless fully within each of the foregoing constraints established by Applicant for the exemplary' preferred implementation of the hand-held beverage dispenser 150 according to the second embodiment of the present invention. To be sure, subject only to the general requirement for containment of all fluid conduits to substantially within the extents of the handle body 151, beverage product inlet port 189 may be located at any radial position about the valve body 179d that is within horizontal plane P21, beverage product outlet port 186 may be located at any radial position about the valve body 179d that is within horizontal plane P22, and diluent outlet port 191 may be located at any radial position about the valve body 179d that is within horizontal plane P24. In fact, the radial locations for each should be established in aid of meeting the general requirement. These fully constraint compliant modifications, as described above, are not only advantageous in meeting the general routing requirement for fluid conduits to or from valve body 179d, they may in fact be critical to meeting the general routing requirement for all of the valve bodies 179a-179j. As has repeatedly been noted, and will be repeated again in the discussion of the relevant considerations for optimizing an implementation of the hand-held beverage dispenser 150 of the present invention, the available space substantially within the extents of an otherwise optimized handle body 151 will necessarily be very limited. With that, it is noted that it may be very advantageous to implement each of the various valve bodies 179a-179j with a corresponding beverage product inlet port 189, a corresponding beverage product outlet port 186, and a corresponding and diluent outlet port 191 that are positioned for the particular one of the valve bodies 179a-179j as is collectively optimal for meeting the general containment requirement each of the fluid conduits interfacing with all of the valve bodies 179a-179j. Although this variance is from one valve body to another, it is noted that with additive manufacturing or the like, the variations as now described may be had at no additional manufacturing or maintenance cost. To be sure, these variations are widely implemented in the first preferred implementation of the hand-held beverage dispenser 10 of the present invention, as particularly shown, for example, in Figures 9-15. Additionally, the first diluent inlet port 196 and the second diluent inlet port 197 may be located at any set of radial positions about the valve body 179d that is within horizontal plane P22 and for which the positions are separated one from another as required for compatibility with the elements of the implemented diluent selection valve 181d, as previously discussed, with corresponding rotation about axis 206 of any affected features external to the valve unit 177d. As previously noted, the affected external features will be understood further herein to include those features that directly interface with the valve unit 177d. Although this variation requires some adjustment to ancillary components of the hand-held beverage dispenser 150 of the present invention, such as, for example, aspects of the present invention directed toward facilitating configuration or reconfiguration of diluent selections, it does not require modification of any valve trim, as described further herein, of the valve unit 177d. As described above, variation especially in the radial positions of the various valve ports formed through the side walls of the valve body 179d, may be critical to meeting the general contained routing requirement for all of the fluid conduits interfacing with each of the valve bodies 179a-179j. Although variation on a valve body-to-vaive body basis of the set of radial positions about each one of the valve bodies 179a-179j for placement of its corresponding first diluent inlet port 196 and second diluent inlet port 197 will generally require conforming at least some ancillary components to the individual radial orientation of each of the valve bodies 179a-179j, as will be better understood further herein, it is noted that any cost may be compensated by achieving a more optimized hand-held beverage dispenser 150. Additionally, however, and as will in light of this exemplary' description be appreciated by those of ordinary' skill in the relevant arts, to the extent that such ancillary components are single body or otherwise unitary' components, any single one of which interfaces with all of the valve units 170a-170j, it is possible that the variations as now described, like those previously described, may be had at no additional manufacturing or maintenance cost. Also similar to the previously described variations, it is noted that these variations are to at least some extent implemented in the first preferred implementation of the hand-held beverage dispenser 10 of the present invention, as particularly shown, for example, in Figures 9-15. Finally, it is at least possible to implement at least the broad teachings of the present inventions including variations between a plurality of valve unit groups or, in the most extreme, on a valve unit-by-valve unit basis. As is made very clear through this exemplary' detailed description, however, such extreme variation is not necessary to achieving an operable hand-held beverage dispenser 150 according to the second embodiment of the present invention, or for that matter any embodiment of the present invention. Notwithstanding the disfavor of such variations, however, all such variations are considered within at least the broad scope of the present invention. As previously described, a number of fluid conduits generally provide fluid communication into and out of each valve body 179a-179j, as shown in Figures 77-87 and now described in further detail with respect to the exemplary' preferred implementation of the representative valve body 179d. As particularly shown in Figures 78B and 79-87, and like the previously described first embodiment, in the second embodiment of the hand-held beverage dispenser 150 a dedicated beverage product supply conduit 169d is provided between beverage product inlet 162d and the beverage product inlet port 189 of corresponding valve body 179d for conveying a supplied beverage product from beverage product inlet 162d to valve body 179d. As also shown in the figures, a dedicated beverage product dispensing conduit 173d is provided between the beverage product outlet port 186 of valve body 179d and corresponding beverage product outlet 176d, for selectively conveying the beverage product supplied through beverage product inlet port 189 of valve body 179d from valve body 179d and to beverage product outlet 176d, the selective conveyance being effected by operation of flow control valve 180d, as will be understood further herein. As particularly shown in Figures 77 and 78A-78D, and like the previously described first embodiment, the second embodiment of the hand-held beverage dispenser 150 comprises a set of manifolds for efficiently providing fluid communication of diluents into and out of each valve body 179a-179j. As schematically shown in the figures, a first diluent inlet manifold 163 comprises a common trunk 164 between the first diluent inlet 160 and a plurality of valve supply branches 165a-165j, each valve supply branch 165a-165j corresponding to one of the valve bodies 179a-179j. Similarly, a provided second diluent inlet manifold 166 comprises a common trunk 167 between the second diluent inlet 161 and a plurality of valve supply branches 168a-168i, each valve supply branch I68a-168j corresponding to one of the valve bodies 179a-179j. Finally, a common diluents outlet manifold 170 comprises a common trunk 171 between a plurality of valve dispense branches 172a-172j, each valve dispense branch I72a-172j corresponding to one of the valve bodies 179a-179j, and the single, common diluents outlet 175. Returning then to Figures 77-87, the exemplaiy preferred implementation of the representative valve body 179d of the second embodiment of the band-held beverage dispenser 150 is, among other aspects of the present invention, particularly depicted along with the various fluid conduits of the piping system 158 interfacing or otherwise in fluid communication with the valve body 179d. In the most preferred implementation of the piping system 158 of the second embodiment of the band-held beverage dispenser 150, like the previously described piping system 22 of the first embodiment of the hand-held beverage dispenser 10, valve supply branch 165d is provided between common trunk 164 and the first diluent inlet port 196 of corresponding valve body 179d, for conveying a diluent supplied through first diluent inlet 160 to common trunk 164 from common trunk 164 io valve body 179d. Similarly, valve supply branch 168d is provided between common trunk 167 and the second diluent inlet port 197 of corresponding valve body 179d, for conveying a diluent supplied through second diluent inlet 161 to common trunk 167 from common trunk 167 to valve body 179d. Additionally, valve dispense branch 172d is provided between the diluent outlet port 191 of corresponding valve body 179d and common trunk 171, for selectively conveying a separately selected one of either the diluent supplied through first diluent inlet port 196 of valve body 179d or the diluent supplied through second diluent inlet port 197 of valve body 179d from valve body 179d and to common diluents outlet 175. The selection of one or the other of the diluent supplied through first diluent inlet port 196 or the diluent supplied through second diluent inlet port 197 for selective conveyance from valve body 179d to common diluents outlet 175 is determined by the state of diluent selection valve 181d, as will be better understood further herein. The selective conveyance of the selected diluent from valve body 179d to common diluents outlet 175, on the other hand, is effected by operation of flow control valve 180d, as also wall be better understood further herein. Like the previously described first embodiment, the teachings of the present invention as set forth with reference to the representative valve body 179d of the second preferred implementation of the hand-held beverage dispenser 150 of the present invention are generally extensible to each of the valve bodies 179a-179c and 179e~179j, with slight variance in valve bodies 1791-179j, as noted further herein. That said, and with reference now again to Figures 77-87 and the foregoing detailed discussion of valve body 179d, details of the fluid conduits of the novel piping system 158 of the second embodiment of the present invention are set forth with respect to valve bodies 179a-179c and 179e-179j, thereby further ensuring clarity7 in the discussions to follow.

A valve dispense branch 172h is provided between the diluent outlet port 191 of corresponding valve body 179h and common trunk 171, for selectively conveying a separately selected one of either the diluent supplied through first diluent inlet port 196 of valve body 179b or the diluent supplied through second diluent inlet port 197 of valve body 179h from valve body 179h and to common diluents outlet 175, The selection of one or the other of the diluent supplied through first diluent inlet port 196 or the diluent supplied through second diluent inlet port 197 for selective conveyance from valve body 179h to common diluents outlet 175 is determined by the state of diluent selection valve 181h. The selective conveyance of the selected diluent from valve body 179h to common diluents outlet 175 is effected by operation of flow control valve 180h. As previously noted, the most preferred implementation of the second embodiment of the hand-held beverage dispenser 150 of the present invention includes a pair of ON-OFF flow controls 153i-153j, each dedicated to dispensing a diluent only. As also previously noted, the most preferred implementations of the present invention contemplate that the provision of either the first diluent only or the second diluent only is also end-user selectable. In order to meet these demands, the novel piping system 158 of the second embodiment of the present invention omits the beverage product supply conduits and beverage product dispensing conduits, as otherwise would run to or from the corresponding adjunct valve units 177i-177j, and each corresponding valve body 1791-179j is formed or otherwise provided sans a beverage product inlet port 189 or a beverage product outlet port 186. On the other hand, the valve bodies 179i-179j are formed or otherwise provided with internal structures identical to those of valve bodies 179a-179h, thereby requiring no additional or different valve components for implementation of the desired features. That said, a valve supply branch 165i is provided between common trunk 164 and the first diluent inlet port 196 of corresponding valve body 179i, for conveying a diluent supplied through first diluent inlet 160 to common trunk 164 from common trunk 164 to valve body 179i, and a valve supply branch 1681 is provided between common trunk 167 and the second diluent inlet port 197 of corresponding valve body 179i, for conveying a diluent supplied through second diluent inlet 161 to common trunk 167 from common trunk 167 to valve body 1791. A valve dispense branch 172i is provided between the diluent outlet port 191 of corresponding valve body 179i and common trunk 171, for selectively conveying a separately selected one of either the diluent supplied through first diluent inlet port 196 of valve body 179i or the diluent supplied through second diluent inlet port 197 of valve body 179i from valve body 179i and to common diluents outlet 175. The selection of one or the other of the diluent supplied through first diluent inlet port 196 or the diluent supplied through second diluent inlet port 197 for selective conveyance from valve body 179i to common diluents outlet 175 is determined by the state of diluent selection valve 181i. The selective conveyance of the selected diluent from valve body 179i to common diluents outlet 175 is effected by operation of flow control valve 180i. Likewise, a valve supply branch 165j is provided between common trunk 164 and the first diluent inlet port 196 of corresponding valve body 179j, for conveying a diluent supplied through first diluent inlet 160 to common trunk 164 from common trunk 164 to valve body 1791, and a valve supply branch 168j is provided between common trunk 167 and the second diluent inlet port 197 of corresponding valve body’ 179j, for conveying a diluent supplied through second diluent inlet 161 to common trunk 167 from common trunk 167 to valve body 179j. A valve dispense branch 172j is provided between the diluent outlet port 191 of corresponding valve body’ 179j and common trunk 171, for selectively conveying a separately selected one of either the diluent supplied through first diluent inlet port 196 of valve body 179j or the diluent supplied through second diluent inlet port 197 of valve body 179j from valve body 179j and to common diluents outlet 175. The selection of one or the other of the diluent supplied through first diluent inlet port 196 or the diluent supplied through second diluent inlet port 197 for selective conveyance from valve body 179j to common diluents outlet 175 is determined by the state of diluent selection valve 181j, The selective conveyance of the selected diluent from valve body 179j to common diluents outlet 175 is effected by operation of flow control valve 180j. Turning now to the material and manner of construction of the skeleton of the handle body 151, including the various fluid conduits of the novel piping system 158 of the second embodiment of the present invention, as well as the valve bodies 179a-179j which also together form a part of the novel piping system 158, in addition to the framework of the handle-body 151, it is noted that the material and manner of construction are informed by a number of potentially competing constraints. In particular, these potentially competing constraints include at least those deriving from: (1) the necessary location and minimum necessary fluid flow capacity of each valve port: (2) the necessary’ location and minimum necessary’ fluid flow capacity of each fluid conduit; (3) the ergonomically acceptable shape and maximum acceptable dimensions of the hand-held beverage dispenser; and (4) the maximum acceptable mass of the hand-held beverage dispenser, as previously described or will be understood further herein. More particularly, in this exemplary or any other implementation of hand-held beverage dispenser 150 according to the present invention, the concerns of the following discu ssions must be taken into account. As previously discussed, the beverage product inlet port 189 and the beverage product outlet port 186 must be vertically arranged about each of valve bodies 179a-179b as required for operation of flow control valves 180a-180h, and similarly the first diluent inlet port 196, the second diluent inlet port 197 and the diluent outlet port 191 must be vertically arranged about each of valve bodies 179a~179j as required for operation of flow control valves 180a~180j. Additionally, the vertical arrangement of the first diluent inlet port 196 and the second diluent inlet port 197 about each of valve bodies 179a-179j must comport with requirements for operation of diluent selection valves I81a-181j. Still further, first diluent inlet port 196 and second diluent inlet port 197 must also be radially separated one from the other about valve bodies 179a-179j as required for operation of diluent selection valves 181a-181j. The restriction on the radial placement for the first diluent inlet port 196 and the second diluent inlet port 197, in particular, but to lesser effect on the radial placement of each of the other valve ports of the valve bodies 179a-179j, however, is further exacerbated by the requirement to locate substantially within the extents of the handle body 151 of the hand-held beverage dispenser 150 each fluid conduit interfacing with any valve port of valve bodies 179a-179j. The required placement of each valve port of valve bodies 179a-179j is also limited to the ability within other restrictions to implement or otherwise provide each valve port with at least the minimum necessary' fluid flow capacity to support proper operation of the implemented post-mix type drink dispenser assembly 104, and most preferably also at a flow capacity for meeting performance expectations such as, for example, dispense rate from the hand-held beverage dispenser 150. Each of the foregoing concerns for fluid flow capacity, as well as the requirement for implementing the novel piping system 158 of the second embodiment of the present invention substantially within the extents of the handle body 151 of the hand-held beverage dispenser 150, apply with the same or similar force to all other fluid conduits in any flow path between the fluid inlets 159 provided at the rear end 157 of the handle-body 151 and the fluid outlets 174 provided at the forward end 156 of the bottom 154 of the handle body 151. That said, it is noted that the constraints as applied to the valve ports compete with the constraints as applied to the fluid conduits, at least to the extent that accommodation by the valve ports of the flow' control valves 180a-180j and the diluent selection valves 181a-181j and the constraint of each of the many fluid conduits, each having a hard minimum fluid flow' capacity requirement, to being routed within the limited extents of the handle body 151 of the hand-held beverage dispenser 150. Additionally, however, attaining these requirements is further exacerbated by the need to produce a commercially acceptable product. In particular, the need to produce the handle body 151 of the hand-held beverage dispenser 150 with an ergonomically acceptable shape within the maximum dimensions acceptable and meeting at least minimum requirements for acceptable comfort in hand and ease of use of the hand-held beverage dispenser 150, and likewise to produce a hand-held beverage dispenser 150 within an acceptable total mass for acceptable comfort in hand and ease of use of the hand-held beverage dispenser 150, necessarily limit the extents of the handle body 151. In total, the foregoing concerns increase the importance of selecting a suitable material and manner of construction for at least the handle body 151 of the hand-held beverage dispenser 150 and the components of the novel piping system 158 made unitary or closely integral with the handle body 151. Although other shapes or implementations are possible, each beverage product supply conduit 169a-169h of the exemplars' second preferred implementation of the hand-held beverage dispenser 150 of the present invention comprises an elongate tubular, or other suitably shaped, member routed, substantially within the extents of the handle body 151, between one of the beverage product inlets 162a-162h and the beverage product inlet port 189 of a corresponding one of the valve bodies 179a-179h; each beverage product dispensing conduit 173a-173h of the exemplary preferred implementation comprises an elongate tubular, or other suitably shaped, member routed, substantially within the extents of the handle body 151, between the beverage product outlet port 186 of one of the valve bodies 179a-179h and its corresponding one of the beverage product outlets 176a-176h; the first common trunk 164 and its corresponding valve supply branches 165a-165j of the exemplary preferred implementation of the first diluent inlet manifold 163 comprise an arrangement of generally elongate tubular, or other suitably shaped, members routed, substantially within the extents of the handle body 151, between the first diluent inlet 160, and, for each valve supply branch 165a-165j, the first diluent inlet port 196 of a corresponding valve body 179a-179j; the second common trunk 167 and its corresponding valve supply branches 168a-168j of the exemplary' preferred implementation of the second diluent inlet manifold 166 comprise an arrangement of generally elongate tubular, or other suitably shaped, members routed, substantially within the extents of the handle body 151, between the second diluent inlet 161 and, for each valve supply branch 168a-168j, the second diluent inlet port 197 of a corresponding valve body 179a-179j; and the common trunk 171 and its corresponding valve dispense branches 172a-172j of the exemplary preferred implementation of the common diluents outlet manifold 170 comprise an arrangement of generally elongate tubular, or other suitably shaped, members routed, substantially within the extents of the handle body' 151, between the diluent outlet port 191 of each valve body 179a-179j, through a corresponding valve dispense branch 172a-172j, and to the common diluents outlet 175. Although other methods of manufacturing are possible in accordance with the teachings of the present invention, the complex structure of the most preferred implementation of the hand-held beverage dispenser 150 of the present invention is created using additive manufacturing. More specifically, it is particularly advantageous to 3-D print the valve bodies 179a-179j, and all of the fluid conduits of the piping system 158, unitary with all of the fixed components of the handle body 151. As exemplified in Figures 9-15 corresponding to the first preferred implementation of the hand-held beverage dispenser 10 of the present invention, the elongate tubular, or other suitably shaped, members as placed within the limited extents of the handle body 151 of the exemplary second preferred implementation of the hand-held beverage dispenser 150 of the present invention will occupy much of the available space. As a result, it is desirable, to the extent possible, to eliminate from the construction any support structure not otherwise necessary to the operation of the hand-held beverage dispenser 150. Although support structures such as the internal mesh 21 provided in the first preferred implementation of the hand-held beverage dispenser 10 may readily be included using additive manufacturing, Applicant has found that utilization of a suitable material of construction generally reduces the need for any such support structure. Most preferably, the foregoing components are printed in stainless steel, which, as opposed to the utilization of many other possible materials of manufacture, such as, for example, plastics or resins, eliminates many concerns regarding the use of a potentially hazardous material, and also readily provides the structural strength to eliminate any need otherwise for support structures, while also enabling manufacture within suitable mass requirements. Additionally, the use of stainless steel facilitates routine cleaning, and also results in a durable product notwithstanding the challenging environment in which the hand-held beverage dispenser 150 will be used. In the most preferred manufactures, however, the interstices 309, voids and other like spaces substantially within the extents of the handle body 151 and about the valve bodies 179a-179j and provided fluid conduits are filled with a food safe antifungal foam or like filler, thereby not only simplifying cleaning of the hand-held beverage dispenser 150, but also providing additional, but lightweight, stabilization for the valve bodies 179a-179j and fluid conduits, which may reduce the probability of damage in use of the hand-held beverage dispenser 150. Additional optimizations, however, are possible beyond the described careful choices of materials for the handle body 151, valve bodies 179a-179j and fluid conduits of the piping system 158 of the hand-held beverage dispenser 150; thoughtful routing of the fluid conduits substantially within the extents of the handle body 151, as may also be aided by additive manufacturing techniques and the like; and inventive arrangement within the valve bodies 179a-179j of the additional components implementing the valve units 177a-177j. For example, as shown in Figures 79-87 for the exemplary valve body 179d, the first diluent inlet port 196, the second diluent inlet port 197 and the diluen t outlet port 191 of each of the valve bodies 179a-179j, as well as each corresponding interfacing fluid conduit, are all implemented in the shape of a horizontal!}' oriented obround. In this manner, the corresponding fluid conduits may, without loss of fluid flow capacity, be placed within a smaller vertical span than would be possible utilizing typically implemented round shapes. Referring now’ to Figures 88-89, the handle body 151 of the hand-held beverage dispenser 150, as implemented for the most preferred implementation of the second embodiment of the hand-held beverage dispenser 150 of the present invention, is generally shown in its “stripped down” state, as previously shown in Figures 72-76 and described in detail with reference to Figures 72-76, Whereas the handle body 151 is shown in Figures 72-76 completely devoid of other components of the beverage dispenser 150 of the present invention, the views of Figures 88-89 show the handle body 151 with the complete valve trim of valve unit 177d received within the single exemplary representative valve body 179d in a state that will further herein be understood is an early stage of assembly about the handle body 151 of the handheld beverage dispenser 150. Additionally and as will also be better understood further herein, the depicted early stage of assembly includes population of each of the valve bodies 179a-179j with an upper seal 259 for use in connection with the flow control valves 180a-180j of the respective valve units 177a-177j. Although not further discussed here, an upper seal 259 of the present invention is shown in detail in, and likewise described in detail with reference to. Figures 97-100, and placement of the upper seals 259 as shown in Figures 88-89 is shown in detail in, and likewise described in detail with reference to, Figures 101-104. Other than the presence of these features, however, the handle body 151 is as show n and described with respect to Figures 72-76. Likewise, representative valve body 179d is presented in Figures 88-89 as has been particularly shown in Figures 79-87, and described in great detail with reference to Figures 79-87 and others. As previously noted, and particularly shown in the cross-sectional elevational view of Figure 89, the valve body 179d is depicted in Figures 88-89 with the complete valve trim of valve unit 177d received therein. Assembly and placement of the valve trim for valve unit 177d is shown in detail in, and likewise described in detail with reference to, Figures 105-112. Of present note, however, the valve unit 177d is shown to comprise a diluent selection valve 181d and a flow control valve 180d. The previously mentioned open topped cup 207, as also previously noted to be a key component of the diluent selection valve 18 Id, is shown toward the bottom 154 of the handle body 151. The open topped cup 207 of the present invention is shown in detail in, and likewise described in detail with reference to, Figures 90-93. As will be understood further herein, the open topped cup 207 is cooperatively adapted with the valve body 179d to implement the diluent selection valve 18Id as a novel cylindrically formed gate valve. As will also be understood further herein, the open topped cup 207 is further cooperatively adapted with the valve body 179d and the valve trim assembly 227, discussion of which immediately follows, to act as a portion of the valve body in implementation of the flow- control valve 180d, thereby inventively enabling implementation of the multi-valve valve unit 177d of the present invention in a physical volume far less than that which would otherwise be required. The briefly mentioned valve trim assembly 227, as will further herein be understood to be a key component of the flow control valve 180d, is shown as generally running from top 152 to bottom 154 of the handle body 151, and as partially received within an interior space 213 of the open topped cup 207. The valve trim assembly 227 is shown in detail in, and likewise described in detail with reference to, Figures 94-96. Referring now to Figures 90-93, the preferred implementation of a novel open topped cup 207, which, as will be better understood further herein, is cooperatively adapted with the specially formed valve body 179d, as has herein been described in detail, to form the diluent selection valve 181d of the inventive valve unit 177d for the hand-held beverage dispenser 150 of the present invention, is now shown and described in detail. As shown in the figures, the open topped cup 207 generally comprises a cylindrical sidewall 208 having a cylindrical exterior surface 209 and a cylindrical interior surface 210, and projecting upwardly from a closed bottom 221 of the cup 207 to form an interior space 213 as defined in large part by the cylindrical interior surface 210. As suggested by those parts of the prior detailed description of the exemplary valve body 179d, many, if not most, of the features of the open topped cup 207 must be provided to specification in order to cooperate with the valve body 179d as intended for implementation of the diluent selection valve 181d. Additionally, however, as has been noted but will nonetheless be better understood further herein, the open topped cup 207 is further cooperatively adapted with both the exemplary valve body 179d and the valve trim assembly of the flow control valve 180d to form the flow control valve 180d of the inventive valve unit I77d for the hand-held beverage dispenser 150 of the present invention. The requirement of the specially formed cup 207 to simultaneously operate as components of very different valve structures, as will be appreciated further herein, only reiterates that the features of the open topped cup 207 must be provided to specification. As noted in the prior detailed description of the exemplary valve body 179d, the open topped cup 207 is received through the circular open end 199 at the bottom 198 of the exemplary' valve body 179d, and retained in place substantially within lower chamber 192 of the exemplary valve body 179d. As also noted in the prior detailed description of the exemplary’ valve body 179d, the upper edge 211 of the cylindrical side wall 208 of the open topped cup 207 abuts a shoulder 194 formed at the top of the lower chamber 192. Because, as will be better understood further herein, the open topped cup 207 is a least partially rotatable as retained in place, the shoulder 194 is formed at the top of the lower chamber 192 as a planar surface. As a result, the upper edge 211 of the cylindrical side wall 208 is also most preferably planar. As also set forth in the prior detailed description of the exemplary' valve body 179d, the dimensions for the shoulder 194 are specified in terms of the dimensions of various aspects of the open topped cup 207, In reality, the exemplary valve body 179d and the open topped cup 207 are cooperatively formed within the specified bounds as set forth in the prior detailed description, taking into account the relative importance of one feature or another to implementation of one or another cooperating component. For example, it may be considered that the exemplary valve body 179d must be formed with a largely predetermined overall height, the interior surfaces must be stepped, the exemplary valve body 179d must be of sufficient volume to maintain acceptable fluid flow rates therethrough, valve trim in addition to that required for the diluent selection valve 181d must be accommodated, and the like. Similarly , it may be considered that the open topped cup 207 must accommodate components in addition to those which are required in implementation of the diluent selection valve 18Id, the cylindrical side wall 208 of the open topped cup 207 must be of structurally sound thickness, and the like. Ail of these considerations, however, will with the aid of this exemplary detailed description and the guidance presented herein, be readily within the ordinary' skill in the relevant arts. In any case, the cylindrical exterior surface 209 and the cylindrical interior surface 210 are formed according within the specifications set forth in the prior detailed description of the exemplary' valve body 179d. In meeting the specifications, however, it is noted that a circumferential groove 220 is provided about the lower exterior portion 216 of the open topped cup 207. As will be better understood herein, the this circumferential groove 220 is sized, shaped and otherwise adapted to operably retain a lower seal 225, such as an O-ring, for the diluent selector valve 18Id. As will be described further herein, it is in fact the open topped cup 207 with the lower seal 225 in place within the circumferential groove 220 about the lower exterior portion 216 of the open topped cup 207. As a result, there will necessarily be some gap between the cylindrical exterior surface 209 of the open topped cup 207 and the cylindrical interior wall 193 of the lower chamber 192 of the exemplary valve body 179d, and which must at least be accounted for within the guidelines specified in the prior detailed description of the exemplary valve body 179d for the relative dimensions of the open topped cup 207 and the exemplary valve body 179d. Finally, one last provision is specifically made in the open topped cup 207 in implementation of the flow control valve 180d. As particularly shown in Figure 93, a cylindrical receptacle 215 is centrally formed in the bottom 214 of the interior space 213 of the open topped cup 207. As will be fully understood further herein, the cylindrical receptacle 215 is sized and otherwise adapted to conformingly receive the fixed end of a poppet spring 273, such as is well known in the relevant arts, for operation of the flow control valve 180d. In addition to conforming to the exterior circumference of the poppet spring 273, the cylindrical receptacle 215 should be of sufficient depth to stably fix the received end of the poppet spring, and maintain at least the received end of the poppet spring about the central axis 206 of the val ve body 179d. Turning then to those remaining features of the open topped cup 207 as are specifically provided in implementation of the diluent selection valve 181d, and referring particularly to Figures 90, 91 and 93, there is shown a notch 212 as formed or otherwise provided at the upper edge 211 and about a portion of the cylindrical sidewall 208 of the open topped cup 207. As will be better understood further herein, the notch 212 cooperates with the larger intact portion of the upper edge 211 of the sidewall 208 of the open topped cup 207 to form a cylindrical gate for the implemented diluent selection valve 18id, and, in particular, for alternately allowing or blocking fluid flow though one or the other of the first diluent inlet port 196 and the second diluent inlet port 197. As best shown in Figures 85-87, each of the first diluent inlet port 196 and the second diluent inlet port 197 are formed or otherw ise provided through the side wail of the exemplary valve body 179d at the uppermost portion of the lower chamber 192 and as near as otherwise practicable to the lower valve seat 195, which location is identified as horizontal plane P23. As shown in the figures, the specified location places each of the first diluent inlet port 196 and the second diluent inlet port 197 just slightly below the shoulder 194 against which the upper edge 211 of the cylindrical side wall abuts, as the open topped cup 207 is operably received in place within the lower chamber 192 of the exemplar}' valve body 179d. As previously noted, the open topped cup 207 is at least partially rotatable about central axis 206 when operably in place within the lower chamber 192 of the exemplary valve body 179d. In particular, the open topped cup 207 must be sufficiently rotatable as to selectively align the notch 212 in the upper edge 211 of the sidewall 208 of the open topped cup 207 with either one of the first diluent inlet port 196 and the second diluent inlet port 197 formed through the side wall of the exemplary valve body 179d. To this end, it is observed that the notch 212 in the upper edge 211 of the sidewall 208 of the open topped cup 207 is formed horizontally along the upper edge 211, and is specifically formed to fully encompass either of the first diluent inlet port 196 and the second diluent inlet port 197, but also to sufficiently conform about the either of the first diluent inlet port 196 and the second diluent inlet port 197 as to ensure that as flow from one of first diluent inlet port 196 and the sec ond diluent inlet port 197 is allowed to pass through the aligned notch 212, flow through the other one of the first diluent inlet port 196 and the second diluent inlet port 197 is blocked by an intact portion of the sidewall 208 of the open topped cup 207, and vice versa. While, as previously noted, the open topped cup 207 must be sufficiently rotatable as to selectively align the notch 212 wdth either one of the first diluent inlet port 196 and the second diluent inlet port 197, Applicant has found it desirable to limit the rotation of the open topped cup 207 to only that which is necessary in operation of the diluent selection valve 191d. As will be better understood further herein, this limitation also contributes to the previously mentioned most preferably implemented poka-yoke mechanism for the hand-held beverage dispenser 150 of the present invention, as will be better understood further herein. To this end, it is noted that the most preferred implementation of the exemplary valve body 179d comprises a notch 201 formed in the circular open end 199 at the bottom 198 of the valve body 179d, as particularly shown in Figures 79-80, 83-84 and 86-87, and provided expressly to be used in connection the stop tab 217 provided or otherwise formed at the lower exterior portion 216 of the open topped cup 207, as best shown in Figures 90 and 92. As best shown in Figure 92, the stop tab 217 comprises a first edge 218 and a second edge 219, as shown in Figures 90 and 92. As clearly shown in Figures 90 and 92, the stop tab 217 extends radially outward beyond the cylindrical exterior surface 209 of the cylindrical side wall 208 of the open topped cup 207 and therefore cannot be received within the lower chamber 192 of the exemplary valve body 179d. Instead, however, the stop tab 217 is sized, shaped and otherwise adapted to move freely substantially within the extents of the notch 201 previously described as being formed in the circular open end 199 of the exemplary valve body’ 179d. In particular, the operably in place open topped cup 207 may rotate counterclockwise about the cen tral axis 206 until the first edge 218 of the s top tab 217 of the open topped cup 207 makes blocking contact with the edge 203 of the first stop 202 at the bottom 198 of the exemplary' valve body 179d. Likewise, the operably in place open topped cup 207 may rotate clockwise about the central axis 206 until the second edge 219 of the stop tab 217 of the open topped cup 207 makes blocking contact with the edge 205 of the second stop 204 at the bottom 198 of the exemplary valve body 179d. In order to ensure that the contact between the first edge 218 of the stop tab 217 of the open topped cup 207 and the edge 203 of the first stop 202 at the bottom 198 of the exemplary’ valve body 179d is predictable and results in rotation of open topped cup 207 by the calculated or otherwise determined desired angle of rotation, the first edge 218 of the stop tab 217 of the open topped cup 207 is formed to lie in a vertical plane RI intersecting the central axis of the open topped cup 207, as shown in Figure 92, and therefore the central axis 206, ensuring that the first edge 218 of the stop tab 217 of the open topped cup 207 will meet face to face with the edge 203 of the first stop 202 at the bottom 198 of the exemplary valve body 179d. likewise, in order to ensure that the contact between the second edge 219 of the stop tab 217 of the open topped cup 207 and the edge 205 of the second stop 204 at the bottom 198 of the exemplary valve body 179d is predictable and results in the desired rotation of open topped cup 207, the second edge 219 of the stop tab 217 of the open topped cup 207 is formed to lie in a vertical plane R2 intersecting the central axis of the open topped cup 207, as shown in Figure 92, and therefore the central axis 206, ensuring that the second edge 219 of the stop tab 217 of the open topped cup 207 will meet face to face with the edge 205 of the second stop 204 at the bottom 198 of the exemplary valve body 179d. As previously noted, establishment of the congruent central angle of the diluent inlet ports 196, 197 has a ripple effect constraining, or even largely defining, the implementation of many aspects of the present invention. As implemented, it is clear that the angle of rotation of the open topped cup 207 that is necessary' for operation of the diluent selection valve I91d is equal to the congruent central angle of the diluent inlet ports 196, 197. In order to achieve the full desired rotation, the congruent central angle of the stop tab 217 must be taken into account. Taking the congruent central angle of the stop tab 217, the desired rotation of the open topped cup 207 is achieved by establishing the congruent central angle of the notch 210 as equal to the sum of the congruent central angle of the diluent inlet ports 196, 197 and the congruent central angle of the stop tab 217. Finally, and as will be better understood further herein, operation of the diluent selection valve 181d in use of the hand held beverage dispenser of the present invention requires manual rotation of the open topped cup 207 while it is installed in place with the exemplary valve body 179d. In order to facilitate this task, a blind slot 223 or like provision is formed on the bottom side 222 of the closed bottom 221 of the open topped cup 207 for engagement with a flathead screwdriver or a like implement, as best shown in Figures 90-92. In order to further facilitate operation of the diluent selection valve 181 d, however, Figure 92 shows that indicia of alignment 224 may be formed in, printed on, or otherwise applied to the bottom side 222 of the closed bottom 221 of the open topped cup 207. As the exemplary implementation now shown and described, an indicium 224 in the form of an arrowhead is applied to the bottom side 222 of the closed bottom 221 of the open topped cup 207, and as will be better understood further herein, is used to point to one of a set of indicia provided at a location at or about the bottom 198 of the exemplary valve body 179d, and which indicia are adapted to distinguish the first diluent from the second diluent. Referring now to Figures 94-96, tire preferred implementation of a novel valve trim assembly 227, which, as will be better understood further herein, is cooperatively adapted with the specially formed valve body 179d, as has herein been described in detail, as well as with the previously described open topped cup 207, to form the flow control valve 180d of the inventive valve unit 177d for the hand-held beverage dispenser 150 of the present invention, is now shown and described in detail. As will be better understood further herein, the valve trim assembly 227 is fashioned to operate within an internal space formed by a cooperative arrangement between the previously described exemplary valve body 179d and the also previously described open topped cup 207. hi particular, the upper portion of the internal space is broadly formed by the upper chamber 185 and the cylindrical interior wall 188 of the intermediate chamber 187 of the exemplary valve body 179d, and the lower portion of the internal space is broadly formed by the cylindrical interior surface 210 of the cylindrical side wall 208 and the bottom 214 of the interior space 213 defined by the cylindrical interior surface 210 of the open topped cup 207. As will be better understood in the discussions to follow', the novel and inventive utilization of space formed for implementation of a first type of valve in implementing a wholly different type of valve enables Applicant to not only provide on demand diluent selection, but also allows Applicant provide at least as many beverage selections as do many other bar guns lacking the novel on demand diluent selection of the hand-held beverage dispenser 150 of the present invention. In any case and as showm in the figures, the preferred implementation of the valve trim assembly 227 for use in the flow’ control valve 180d of the valve unit 177d of the hand-held beverage dispenser 150, generally comprises a most preferably cylindrical valve rod 228 having disposed thereon a first, upper reciprocating sealing member 243 and a second, lower reciprocating sealing member 252. As will be better understood further herein, each of the first, upper reciprocating sealing member 243 and a second, lower reciprocating sealing member 252 implement a poppet-type valve, and the first, upper reciprocating sealing member 243 additionally implements a specially formed wiper seal. As particular shown in Figure 96, the midsection 232 of the valve rod 228 includes a most preferably unitary first retainer 234 for dependently supporting the upper reciprocating sealing member 243. Importantly, the unitary first retainer 234 also provides precise positioning along the valve rod 228 for the upper reciprocating sealing member 243. As also particularly shown in Figure 96, the first retainer 234 comprises a first, upper annular disk 235 and a second, lower annular disk 236. As will be better understood further herein the first, upper annular disk 235 provides positioning and structure for the valve face 248 of the upper reciprocating sealing member 243, while the second, lower annular disk 236 provides structure and stability for the upper reciprocating sealing member 243. As also particularly shown in Figure 96, the lower portion 237 of the valve rod 228 includes a most preferably unitary second retainer 238 for dependently supporting the lower reciprocating sealing member 252. Importantly, the unitary second retainer 238 also provides precise positioning along the valve rod 228 for the lower reciprocating sealing member 252. As also particularly shown in Figure 96, the second retainer 238 comprises a first, upper annular disk 239 and a second, lower annular disk 240. As will be belter understood further herein the first, upper annular disk 239 provides positioning and structure for the valve face 257 of the lower reciprocating sealing member 252, while the second, lower annular disk 240 provides structure and stability for the lower reciprocating sealing member 252. Referring now to each of Figures 94-96, the first, upper reciprocating sealing member 243 is described in detail, as cooperatively adapted for operation against the upper valve seat 190 provided about the transition between the upper chamber 185 of the valve body 179d and the intermediate chamber 187 of the valve body 179d for the flow control valve 180d. As shown in the figures, the first, upper reciprocating sealing member 243 comprises an annular body 244 of a first configuration in the general form of a spool, and which is most preferably provided as a unitary element comprising rubber or like material. In any case, the upper reciprocating sealing member 243 is preferably formed as an over-mold to the valve rod 228 between the first, upper annular disk 235 and the second, lower annular disk 236 of the first retainer 234, thereby not only simplifying manufacture of the valve trim assembly 227 but also obviating issues of leakage along the valve rod 228. As also shown in the figures, the annular body 244 of the first configuration comprises an upper rim 245 and a lower rim 249, the upper rim 245 and lower rim 249 being separated by a preferably deeply curved barrel 251, the provision of which avoids excess friction between the first, upper reciprocating sealing member 243 and the cylindrical interior wall 188 of the intermediate chamber 187 of the exemplary’ valve body 179d. The upper rim 245 of the annular body 244 of the first configuration comprises a cylindrical outer edge 246, which loosely conforms to the cylindrical interior wall 188 of the intermediate chamber 187 of the exemplary’ valve body 179d to provide stability and centering about the central axis 206 for the upper reciprocating sealing member 243. Additionally, a downwardly angled top surface 247 is formed on the upper rim 245 to implement the poppet-type valve face 248 of the upper reciprocating sealing member 243. As will be appreciated by those of ordinary’ skill in the relevant arts, however, the top surface 247 may be downwardly sloping as depicted, or may take any other profile operatively sized, shaped and otherwise adapted to produce a valve face 248 adapted to precisely mate in sealing engagement with the previously described upper valve seat 190 provided about the transition between the upper chamber 185 of the valve body 179d and the intermediate chamber 187 of the valve body' 179d in tire exemplary implementation of the flow control valve 180d. The lower rim 249 of the annular body 244 of the first configuration is sized, shaped and otherwise cooperatively adapted with the cylindrical interior wall 188 of the intermediate chamber 187 of the exemplary valve body 179d to operate as a customized reciprocating wiper seal to segregate, and provide fluid isolation between the interior space of the exemplary valve body 179d above the lower rim 249 and the interior space of the exemplary valve body 179d below the lower rim 249, as the valve trim assembly 227 reciprocates up and down within the exemplary’ valve body 179d. To this end, the outer edge 250 about the lower rim 249 is formed to closely conform to the cylindrical interior wall 188 of the intermediate chamber 187 of the exemplary valve body 179d. Referring still to Figures 94-96, the second, lower reciprocating sealing member 252 is described in detail, as cooperatively adapted for operation against the lower valve seat 195 provided about the transition between the intermediate chamber 187 of the valve body 179d and the lower chamber 192 of the valve body 179d for the flow control valve 180d. As shown in the figures, the second, lower reciprocating sealing member 252 comprises an annular body 253 of a second configuration in the general form of a plug, and which is most preferably provided as a unitary element comprising rubber or like material. In any ease, the lower reciprocating sealing member 252 is preferably formed as an over-mold to the valve rod 228 between the first, upper annular disk 239 and the second, lower annular disk 240 of the second retainer 238, thereby not only simplifying manufacture of the valve trim assembly 227 but also obviating issues of leakage along the valve rod 228. As also shown in the figures, the annular body 253 of the second configuration comprises a circumferential shoulder 254 about the top end of the annular body 253 of the second configuration, and is formed atop a low profile base 258, the provision of which avoids excess friction between the second, lower reciprocating sealing member 252 and the cylindrical interior surface 210 of the cylindrical side wall 208 of the open topped cup 207, as operably received within the lower chamber 192 of the exemplary valve body 179d. The circumferential shoulder 254 of the annular body 253 of the second configuration comprises a cylindrical outer edge 255, which loosely conforms to the cy lindrical interior surface 210 of the cylindrical side wall 208 of the open topped cup 207, as implemented in the diluent selection valve 181d, to provide stability and centering about the central axis 206 for the lower reciprocating sealing member 252. Additionally, a downwardly angled top surface 256 is formed on the circumferential shoulder 254 to implement the poppet-type valve face 257 of the lower reciprocating sealing member 252. As will be appreciated by those of ordinary skill in the relevant arts, the downwardly sloping top surface 256 must be sized, shaped and otherwise adapted io produce a valve face 257 adapted to precisely mate with the lower valve seat 195 provided about the transition between the intermediate chamber 187 of the valve body 179d and the lower chamber 192 of the valve body 179d for the flow control valve 180d. In an important aspect of the cooperative integration of the valve trim assembly 227 and the open topped cup 207, the bottom end 241 of the valve rod 228 is particularly shown in Figures 95-96 to comprise a protuberance 242 extending downwardly extending the valve rod 228 beyond the second, lower annular disk 240 of the second retainer 338. On the other hand, it is recalled that a cylindrical receptacle 215 is centrally formed m the bottom 214 of the interior space 213 of the open topped cup 207 of the diluent selection valve 18Id. Additionally, the detailed description of the open topped cup 207 notes that the provided cylindrical receptacle 215 is sized and otherwise adapted to conformingly receive the fixed end of a poppet spring 273 for operation of the flow control valve 180d. The protuberance 242 is adapted to receive thereabout the reciprocating end of the poppet spring 273, and thus should be sized and otherwise adapted to conformingly engage the interior portion of the poppet spring 242. Finally, the upper portion 229 of the valve rod 228 is shown in Figures 94-96 to be substantially narrowed relative to the rest of the valve rod 228. The narrowed upper portion 229 of the valve rod 228 is adapted to readily pass through the flow control valve actuator orifice 183 shown at the top 182 of the exemplary valve body 179d, as has herein been described in detail, including through an upper seal 259, as provided for the exemplary flow control valve 180d. As shown in Figures 97-100, the seal 259 is adapted to fit conformingly and sealingly within the flow control valve actuator orifice 183, and thereafter to sealingly receive the narrowed portion 229 of the valve rod 228 through a provided central orifice 262, and making the uppermost portion of the valve rod 228 available for use as an actuator for the flow control valve 180d, To this end, a keeper groove 231 is circumferentially formed about the top end 230 of the valve rod 228, As will be detailed further herein, the keeper groove 2.31 is utilized in cooperation with various button caps to securely but removably retain the button caps in place at the top end 230 of the valve rod 228. Referring now to Figures 97-100, various details of the upper seal 259 for the exemplary flow control valve 180d of the present invention are shown and described. In the preferred implementation of the flow control valve 180d of the present invention, the upper seal 259 is formed as a grommet-shaped plug 260 comprising rubber or like material. The plug 260 is provided with a circumferential shoulder 261 about the top, which, as will be better understood further herein, may in use rest upon the top 182 of the exemplary valve body 179d about the flow control valve actuator orifice 183. As previously mentioned, the plug 260 comprises a central orifice 262 running top to bottom through the plug 260, and which is sized, shaped and otherwise adapted to sealingly engage the outer surface of upper portion 229 of the generally cylindrical valve rod 288. As particularly shown in Figures 97, 98 and 100, die bottom edge of the central orifice 262 is preferably chamfered or otherwise relieved, in order to prevent loss of integrity or other damage to the upper seal 259 as the valve unit 177d is being assembled, and the top edge of die central orifice 262 may also be chamfered or otherwise relieved as shown in die figures and may be desired. Finally, the plug 260 has a retention groove 263 formed about the midsection of the plug 260. As will be appreciated by those of ordinary skill in the relevant arts, the retention groove 263 should be sized, shaped and otherwise adapted to engage the annulus 184 formed within the flow control valve actuator orifice 183 of the exemplary valve body 179d, and which is provided for this puipose. Turning now to Figures 101-104, assembly of the hand-held beverage dispenser 150 according to the second preferred embodiment of the present invention begins with insertion of an upper seal 259 for the flow control valve 180d into the flow control valve actuator orifice 183 of the exemplary valve body 179d. Upon application of gentle top down force, such as bv a thumb press, the upper seal 259 of the flow control valve 180d will readily take the correct position within the flow control valve actuator orifice 183 of the exemplary valve body 179d, with the retention groove 263 fully engaged by the annulus 184 formed within the flow control valve actuator orifice 183, and the circumferential shoulder 261 resting securely at the top 182 of the exemplary valve body, as shown in Figures 102-103. This process, as described for operably placing the upper seal substantially within the exemplary' valve body 179d, is then repeated for insertion of an upper seal 259 into the flow control valve actuator orifice 183 at the top 182 of each remaining valve body 179a-179c and 179e-179j of the handle body 151, which is shown in Figure 104 in the completed state. Tn the next stage of assembly, each of the valve bodies 179a-179j is fully populated with its corresponding valve trim. In accordance with the preferred implementation of the hand-held beverage dispenser 150 of the second embodiment of the present invention, the valve him as cooperatively adapted with a corresponding one of the valve bodies 179a-179j to form each valve unit 177a-177j, is shown in Figures 105-106 to comprise an open topped cup 207, a valve trim assembly 227 for the flow control valve 180d; a lower seal 225 for the diluent selection valve 181d, such as may comprise an O-ring 226 or the like; and a poppet spring 273. These individual valve trim components assemble within a corresponding one of the valve bodies 179a-179j to form a compactly integrated valve trim arrangement 308, as illustrated in isolation in Figures 107-108. As will be better understood further herein, each valve body 179a-179j is cooperatively fitted with a valve trim arrangement 308, although as has been noted and will also be better understood further herein some functionality may, if purposefully desired, be limited with respect to one or more of the valve units 177a-l 77j. In any case, the implementation for any fully functional one of the valve units 177a-177j is now described with reference to the representative exemplary valve unit 177d. As wdll be better understood further herein, valve body 179d is cooperatively fitted with a valve trim arrangement 308 to form corresponding valve unit 177d, w'hich comprises a corresponding dual flow' control valve 180d and an independently operated corresponding diluent selection valve 181d. The dual flow control valve 180d implements single simultaneous flow’ control for two isolated flow paths through the valve unit 177d, w'hile the independently operated diluent selection valve 181d implements a 3 w'ay / 2 position valve adapted to selectively place one of two isolated flow paths into the valve unit 177d in fluid communication within the valve unit 177d with one of the two isolated flow paths through the valve unit 177d controlled by the flow control valve 180d. Importantly, the flow control valve 180d and the diluent selection valve 181d, as w?ell as all fluid flow paths therebetween, are substantially implemented within the compact space of the valve body 179d. As previous!}' noted, assembly of the valve units !77a-177j of the hand-held beverage dispenser 150 of the second embodiment begins with placement of the upper seals 259 of the flow control valves 180a-180j. As particularly illustrated in Figure 101 with respect to the representative exemplary valve unit 177d, the upper seal 259 for the flow control valve 180d is inserted into the valve body 179d through tire flow control valve actuator orifice 183 located at the top 182 of the valve body 179d. As particularly illustrated in Figure 109, however, the individual valve trim components of the previously described valve trim arrangement 308 are all introduced into the valve body 179d through the circular open end 199 located at the bottom 198 of the valve body 179d. Although other processes may be determined in light of the teachings of this exemplary disclosure, in the preferred method of the present invention assembly of the valve units 177a-177j, as again described with reference to the representative exemplary valve unit 177d, continues with insertion of the valve trim assembly 227 for the flow control valve 180d through the circular open end 199 of the valve body 179d and substantially into the chambers of the valve body 179d. If not preassembled, the O-ring 226, or a like valve seal 225, is then operatively placed within the circumferential groove 220 about the lower exterior portion 216 of the open topped cup 207 as provided for receiving lower seal 225 for the diluent selection valve 18Id. In any case, with the O-ring 226, or other equivalent seal 225, properly seated within the circumferential groove 220, the poppet spring 273 is lowered into the interior space 213 of the open topped cup 207, and the bottom end of the poppet spring 273 is inserted into the cylindrical receptacle 215 formed in the bottom 214 of the interior space 213 of the open topped cup. At this stage of assembly, the open topped cup 207, with the lower seal 225 for the diluent selection valve 18Id properly seated within circumferential groove 220 and the poppet spring 273 positioned within the cylindrical receptacle 215, the subassembly about the open topped cup 207 is then also inserted through the circular open end 199 of the valve body 179d and into the lower chamber 192 of the valve body 179d, where the free end of the poppet spring 273 will engage about the protuberance 242 at the bottom end 241 of the valve trim assembly 227. With the complete valve trim arrangement 308 preliminarily inserted through the circular open end 199 of the valve body 179d and substantially received therein, sufficient force is applied to the bottom side 222 of the closed bottom 221 of the open topped cup 207 to work the valve trim arrangement 308 through the chambers of the valve body 179d until the top end 230 of the valve rod 228 of the valve trim assembly 227 passes through the previously placed upper seal 259 for the flow control valve 181d and protrudes from the flow control valve actuator orifice 183. as shown in Figure 111, and the bottom side 222 of the closed bottom 221 of the open topped cup 207 is substantially seated within the lower chamber 192 of the valve body 179d, as shown in Figure 110. This process, as described for initially placing the previously described valve trim arrangement 308 substantially within the exemplary’ valve body 179d, is then repeated for placement of a valve trim arrangement 308 through the circular open end 199 at the bottom 198 of each remaining valve body 179a-179c and 179e-179j of the handle body 151, working each valve trim arrangement 308 through the respective interior chambers of each valve body 179a -179b and 179e-179j until all are initially seated in place, as shown in Figure 112. Before continuing the description of the assembly process for the valve units 177a-177j, it is emphasized that is veiy important to not tear or otherwise damage the lower seal 225 while operatively placing the valve seal 225, whether placing the valve seal 225 within the circumferential groove 220 about the lower exterior portion 216 of the open topped cup 207 or inserting the open topped cup 207, with an affixed valve seal 225, through the circular open end 199 into the valve body 179d. To be sure, it should be well noted that any injury to the integrity of the valve seal 225 could result in leakage of beverage fluids from the valve unit 177d, potentially rendering the hand-held beverage dispenser 150 temporarily unfit for use pending replacement of the injured valve seal 225. That said, assembly, use and maintenance of the hand-held beverage dispenser 151 of the present invention are generally ail very easy, and accordingly the lower seal 225 is with due care readily properly placed within the circumferential groove 220. For example, io place the depicted exemplary' O-ring 226 from below the open topped cup 207, the aperture of the O-ring 226 is placed over and about the stop tab 217 projecting from the lower exterior portion 216 of the open topped cup 207, allowing the O-ring 226 to safely engage the adjacent portion of the circumferential groove 220. The distal portion of the O-ring 226 is then simply stretched about the closed bottom 221 of the open topped cup 207 to fully engage the circumferential groove 220. Alternatively, the O-ring 226 may be carefully placed over and about the upper edge 211 of the cylindrical side wall 208 of the open topped cup 207, and then urged downward to seat the O-ring 226 within the circumferential groove 220. In any case, to mitigate the risk of damage during the assembly process preassembly of the O-ring 226, or a like valve seal 225, with the open topped cup 207 is recommended in order to provide a measure of additional focus for the task. Continuing then with the assembly process for the valve units 177a-177j, it is again noted that each valve trim arrangement 308, as depicted in Figure 112, is only initially placed. At this juncture much of each valve trim arrangement 308 is merely resting in place, and the full valve trim arrangement 308 for each valve unit 177a-177j must be secured operatively in place within its respective valve body 179a-179j. This is accomplished using a purpose built valve trim retaining member 274, as particularly' shown in Figures 113-115. As will be better understood further herein, the novel purpose built valve trim retaining member 274 as implemented the second embodiment of the present invention not only retains in place each valve trim arrangement 308, but is also adapted, with other components of the hand-held beverage dispenser 151, as have been or will be described, to cooperatively implement the previously mentioned poka-yoke mechanism for delivering fundamental functionality of the each diluent selection valve 181a-181 j. Referring then to Figures 113-114 in particular, a specially formed novel valve trim retaining member 274 is now shown to generally comprise a rigid plate 275 having various unitary', machined, milled, drilled or otherwise provided or formed holes, slots and notches for interoperability with the handle body 151, valve units 177a-177j and a bottom cover 287, as will be described fur ther herein, of the handle body 151. The specially formed novel valve trim retaining member 274 functions primarily to securely retain the valve trim for each valve unit 177a-177j in place substantially within each corresponding valve body 179a-179j, while nonetheless permitting sufficient rotation of the open topped cup 207 retained within each corresponding valve body 179a-179j --- that is, io operate the diluent selection valve 179a-179j retained within each valve body 179a-179j --- to enable user selection of either the first diluent or the second diluent for each corresponding valve body 179a-179j. Additionally, however, and as will be better understood further herein, the valve trim retaining member 274 also cooperates with a bottom cover 287 of the handle body 151, as well as features formed unitary' with the valve bodies 179a-179j and the open topped cups 207 of the diluent selection valves 18la-181 j, to inventively implement enhanced functionality m operation of the diluent selection valves 181a-181j. In implementation of its primary function of providing operably accessible retention of the valve trim for each the valve unit 177a-177j, the valve trim retaining member 274 first retains the valve trim. As will, in light of this exemplary' description, be understood by those of ordinary' skill in the relevant arts, the top side 277 of the valve trim retaining member 274 abuts the bottom sides 222 of the closed bottoms 221 of the open topped cups 207 of each diluent selection valve 181a-181j. To retain the valve trim of each valve unit 177a-177j operably in place within its corresponding valve body 179a-179j, where each abutted open topped cup 207 is fully inserted into the lower chamber of a corresponding valve body 179a-179j such that the upper edge 211 of the cylindrical side wall 208 of the abutted open topped cup 207 is in contact with the shoulder 194 provided about and at the top of the lower chamber 192 of the corresponding at the valve body I79a-179j when the valve trim retaining member 274 is operably secured in place, smooth mounting holes 279 are provided through the rigid plate 275 of the valve trim retaining member 274, As shown in Figure 115, screws 280, or other conventional mounting hardware as may be suitable, are inserted partially through the provided mounting holes 279 to engage corresponding threaded holes 285 the bottom 154 of the handle body 151, thereby removably affixing the valve trim retaining member 274 operably in place adjacent the bottom 154 of the handle body 151, as shown in Figure 116. In further implementation of its primary function of providing operably accessible retention of the valve trim for each the valve unit 177a-l 77j, the valve trim retaining member 274 also provides operable accessibility to the valve trim, as retained in place as described above. As particularly shown in Figures 113, 114 and 116, the rigid plate 275 of the valve trim retaining member 274 comprises a selection access notch 278 for each implemented valve unit 177a-177j. Each selection access notch 278 is principally provided to enable access by a screwdriver, or like implement, to the blind slot 223, or like provision, as previously described to be located on the bottom side 222 of the closed bottom 221 of the open topped cups 207 of each diluent selection valves 181a-181j, and which are clearly showm in Figure 116 to be operably accessible. Additionally and as previously noted, however, the most preferred implementations of the second embodiment of the hand-held beverage dispenser 150 of the present invention contemplate the provision of various indicia of alignment in aid of a user’s selection of a particular diluent. To this end, the bottom side 222 of the closed bottom 221 of the most preferred implementations of the open topped cup 207 of each diluent selection valve 18la-18Ij has been previously described as including an indicium of alignment 224 in the form of an arrowhead. Accordingly, the selection access notches 278 are most preferably sized, shaped or otherwise arranged through and about the valve trim retaining member 274 to provide visual access for utilization of such an indium of alignment 224, or like indicia, as well as to provide physical access to the blind slots 223, or like provision, from the bottom side 283 of the valve trim retaining member 274, as clearly shown in Figure 116. In order to give practical utility to the previously described indicium of alignment 224 as applied to the bottom side 222 of the closed bottom 221 of each open topped cup 207 of the diluent selection valves 181a-181j, however, functionally corresponding indicia of alignment 284 are formed in, printed on or otherwise applied to the bottom side 283 of the valve trim retaining member 274. In the present exemplary description, the letter W, as, for example, may indicate a diluent comprising plain water, is applied to the bottom side 283 of the valve trim retaining member 274 at one side of each provided selection access notch 278 as a first indicium of alignment 284, and the letter S, as, for example, may indicate a diluent comprising soda, is applied to the bottom side 283 of the valve trim retaining member 274 at the opposite side of each provided selection access notch 278 as a second indicium of alignment 284. Of note, the valve trim retaining member 274 is readily removed and replaced to accommodate any desired indicia of alignment 284, As will at this juncture, and particularly in light of this exemplary description, be understood by those of ordinary skill in the relevant arts, the open topped cups 207 of each diluent selection valve 181a-181j, in the configuration depicted in Figure 116, are free to rotate about the central axis 2.06 within the lower chamber 192 of the corresponding valve body 179a-179j, limited only by the stop tab 217 of the rotating open topped cup 207 being restricted to travel along the arc about the circular open end 199 at the bottom 198 of the corresponding valve body 179a-179j between the edge 203 of the first stop 202 and the edge 205 of the second stop 204 of the corresponding valve body 179a-179j, as reduced by the width of the stop tab 217. Referring now to the specific implementation of the herein described exemplary' diluent selection valve 18Id, it is noted that as depicted in Figures 90 and 92, in particular, the stop tab 217 provided at the lower exterior portion 216 of the open topped cup 207, the arrowhead implementing the indicium of alignment 224 applied to the bottom side 222 of the closed bottom 221 of the open topped cup 207, and the horizontally oriented notch 212 formed at the upper edge 211 and about a portion of the cylindrical side wall 208 of the open topped cup 207 are all three aligned with a common radial line from the central axis 206. Although other implementations may be had, the following discussion will, for purposes of visualization, assume the particular arrangement of the exemplary implementation. Referring now to Figure 116, and with reference to Figure 112 and to Figures 79-87 and 93-93 as needed, the operably implemented valve unit 177d is shown with the first edge 218 of the stop tab 217 projecting from the lower exterior portion 216 of the open topped cup 207 of diluent selection valve I79d positioned adjacent to the edge 203 of the first stop 202 formed by the notch 201 in the circular open end 199 at the bottom 198 of the valve body 179d. As will, in light of this exemplary description, be understood by those of ordinary' skill in the relevant arts, the foregoing alignment within the exemplary valve body 179d places the horizontally oriented notch 212 in the cylindrical sidewall 208 of the open topped cup 207 of the diluent selection valve 181d in line with the first diluent inlet port 196 formed through the side wall of the valve body 179d, and may be referred to as a first operable state of the diluent selection valve 181 d. As particular!}' shown in Figure 116, the foregoing alignment within the exemplary' valve body 179d also causes the arrowhead forming the indicium of alignment 224 on the bottom side 222 of the closed bottom 221 of the open topped cup 207 to align with the letter W forming an indicium of alignment on the bottom side 283 of the valve trim retaining member 274, indicating that in the selected state of the diluent selection valve 19Id, the diluent is plain water. Tn order to then cause valve unit 177d to use soda as the diluent, a flathead screwdriver, or other appropriate implement, is inserted through the selection access notch 278 about the closed bottom 221 of the open topped cup 207 of diluent selection valve 18 Id to engage the blind slot 223 formed on the bottom side 222 of the closed bottom 221. In the present example and from the viewpoint of Figure 116, the flathead screwdriver, or other appropriate implement, is simply used to rotate the open topped cup 207 in the counterclockwise direction until further rotation is blocked by the second edge 219 of the stop tab 217 projecting from the lower exterior portion 216 of the open topped cup 207 of diluent selection valve 179d contacting the edge 205 of the second stop 204 formed by the notch 201 in the circular open end 199 at the bottom 198 of the valve body 179d. As will, in light of this exemplary description, be understood by those of ordinary skill in the relevant arts, the foregoing alignment within the exemplary valve body 179d places the horizontally oriented notch 212 in the cylindrical sidewall 208 of the open topped cup 207 of the diluent selection valve 181d in line with the second diluent inlet port 197 formed through the side wall of the valve body 179d, and may be referred to as a second operable state of the diluent selection valve 18Id. Additionally, the foregoing alignment within the exemplary' valve body 179d also causes the arrowhead forming the indicium of alignment 224 on the bottom side 222 of the closed bottom 221 of the open topped cup 207 to align with the letter S forming an indicium of alignment on the bottom side 283 of the valve trim retaining member 274, indicating that in the selected state of the diluent selection valve fold, soda is selected for the diluent, as desired. As previously mentioned, the novel purpose built valve trim retaining member 274 is, in addition to the foregoing functionality, adapted with other components of the hand-held beverage dispenser 151 to cooperatively implement the variously mentioned poka-yoke mechanism for delivering fundamental functionality of the each diluent selection valve 181a-181j. In particular, the poka-yoke mechanism implements a failsafe provision to ensure that the horizontally oriented notch 212 of the open topped cup 207 of each implemented diluent selection valve 181 a-l81 j is, in use of the hand-held beverage dispenser 150, correctly fully aligned with either the first diluent inlet port 196 or the second diluent inlet port 197 of the corresponding valve body 179a-179j. To that end, the most preferred implementation of the valve trim retaining member 274 is specially adapted to accommodate features of an also specially adapted bottom cover 287 for the handle body 151, As best shown in Figures 113-114, the valve trim retaining member 274 comprises a plurality of arcuate slots 276 corresponding to at least an equal plurality of locking tabs 291 provided on the interior side 290 of the bottom panel 289 of the bottom cover 287 for the handle body 151, as will be understood further herein. In particular, an arcuate slot 276 is provided through the rigid plate 275 of the valve trim retaining member for each valve unit 177a-177j implemented in the hand-held beverage dispenser 151. Each provided arcuate slot 276 is sized, shaped, located one to another and otherwise adapted to enable passage of a corresponding one of the locking tabs 291 provided on the interior side 290 of the bottom panel 289 of the bottom cover 287. As will be better understood further herein, each of the locking tabs 291, which as noted generally dictate the form and position of the arcuate slots 276, is sized, shaped and positioned according to the form, position and size of the arc about the circular open end 199 at the bottom 198 of the corresponding valve body 179a-179j between the edge 203 of the first stop 202 and the edge 205 of the second stop 204 of the corresponding valve body 179a-179j, and, additionally, bv the size and shape of the stop tab 217 projecting from the lower extenor portion 216 of the open topped cup 207 of the corresponding diluent selection valve 179a-179j. In any case, to facilitate the required close cooperation between the bottom cover 287 for the handle body 151 and the valve trim retaining member 274, a hardware pass through hole 281 and a hardware clearance notch 282 are formed through the rigid plate 275 of the valve trim retaining member 274, each of which is sized and positioned to enable free passage through the valve trim retaining member 274 of the attachment hardware 296 for the bottom cover 287 of the handle body 151. Turning now to Figures 117-120, the previously mentioned specialty formed bottom cover 287 for the handle body 151, as provided in accordance with the preferred implementation of the second embodiment of the hand-held beverage dispenser 151 of the present invention, is shown as a single body manufacture generally comprising a substantially planar bottom panel 289 having an aesthetically pleasing wing 288 upwardly extending symmetrically from each side of the bottom panel 289. The exterior of the bottom cover 287 may be, and preferably is, provided with features for enhancing user experience with the hand-held beverage dispenser 150. For example and as particularly shown in Figure 120, the portions of the exterior of the bottom cover 287 may be provided with knurls 297 or other features for facilitating a secure grasp by a user of the handle body 151, notwithstanding the generally fast-paced, and often wet, environments in which it may be expected that the hand-held beverage dispenser 150 will typically be deployed for use. As best shown in Figures 118-119, the interior side 290 of the bottom panel 289 comprises a plurality of upwardly projecting locking tabs 291, and, in particular one locking tab 291 corresponding to each valve unit 177a-177j implementing a diluent selection valve 181a-181j, Each of the provided locking tabs 291 is adapted for insertion through a corresponding one of the previously described arcuate slots 276 provided through the rigid plate 275 of the valve trim retaining member 275, as previously mentioned, and furthermore into a position operative to selectively disable rotation of the open topped cup 207 of the corresponding diluent selection valve 181a-181j from the first operable state of the diluent selection valve 181a-181j to the second operable state of the diluent selection valve 18 la-18 Ij, or to any transitional state between the first operable state and the second operable state as would in any way diminish or otherwise interfere with the fluid flow capacity established for the first operable state, and likewise to disable rotation of the open topped cup 207 of the corresponding diluent selection valve 181a-181j from the second operable state of the diluent selection valve 181a-181j to the first operable state of the diluent selection valve 181a-181j, or to any transitional state between the second operable state and the first operable state as would in any way diminish or otherwise interfere with the fluid flow capacity established for the for the second operable state. In order to achieve the desired a failsafe condition, each locking tab 291 is sized, shaped and positioned such that when the corresponding diluent selection valve 181a-181j is in a “correct selection state” - that is, when either the first edge 218 or the second edge 219 of the stop tab 217 of the open topped cup 207 of the corresponding diluent selection valve 181a-181j is operably adjacent either the first stop 202 or the second stop 204 formed at the ends of the notch 201 formed in the circular open end 199 at the bottom 198 of the corresponding valve body 179a-179j - the locking tab 291 is adapted to pass through a corresponding one of the arcuate slots 276 provided through the valve trim retaining member 274, and extend sufficiently beyond the valve trim retaining member 274, to substantially occupy the arc about the corresponding notch 201. In order to “substantially occupy” the arc about the notch 201, a portion of the locking tab 291, as the locking tab 291 is inserted under the forgoing conditions of a correct selection state, must be positioned sufficiently adjacent whichever of the first edge 218 or the second edge 219 of the stop tab 217 of the open topped cup 207 is opposite whichever of the first edge 218 or the second edge 219 of the stop tab 217 is operably adjacent either the first stop 202 or the second stop 204 formed at the ends of the notch 201. Additionally, however, in order to “substantially occupy” the arc about the notch 201, a portion of the locking tab 291, as the locking tab 291 is inserted under any transitional or other condition of the corresponding diluent selection valve 181a-181j other than one of the two foregoing conditions of a correct selection state, must also sufficiently occupy the intermediate portions of the arc about the notch 201, as located between those portions of the arc that are occupied by the stop tab 217 when operably adjacent either the first stop 202 or the second stop 204 of the notch 201 in a correct selection state of the corresponding diluent selection valve 18J.a-l.81j, such that the locking tab 291 is prevented from fully engaging the notch 201 formed in the circular open end 199 at the bottom 198 of the corresponding valve body 179a-179j, thereby alerting a user to an improperly configured diluent selection valve 181a-181j. As made clear above, the implementation of the upwardly projecting locking tabs 291, including the relationships one to another, is largely dictated by the implementation of the diluent selection valves 181a-181j in connection with the corresponding valve bodies 179a-179j, including the required positioning of the first diluent inlet port 196 and the second diluent inlet port 197. As previously mentioned, and made clearer above, it is the implementation of the upwardly projecting locking tabs 291 that drives the implementation of the arcuate slots 276 through the rigid plate 275 of the valve trim retaining member 274. On the other hand, several features are implemented in the bottom cover 287 to facilitate the required close cooperation between the bottom cover 287 for the handle body 151 and the valve trim retaining member 274. As best shown in Figures 118-119, an outwardly oriented low profile gusset 292 is formed at the convex side of each upwardly projecting locking tab 291. These gussets 292 together form a distributed standoff for the interior side 290 of the bottom panel 289 of the bottom cover 287 from the bottom side 283 of the valve trim retaining member 274. As distributed, the gussets 292 provide uniform contact surfaces for attachment of the bottom cover 287 to the handle body 151, while also providing and maintaining such spacing between the interior side 290 of the bottom panel 289 of the bottom cover 287 and the valve trim retaining member 274 as required for accommodating, for example, attachment hardware for the valve trim retaining member 274 such as the heads of screws 280 or the like. In order to minimize the required spacing, however, the interior side 290 of the bottom panel 289 also comprises a pair of hardware recesses 293, which are sized, shaped and located for additionally accommodating at least a portion of the heads of screws 280 utilized to attach the valve trim retaining member 274 to the bottom 154 of the handle body 151. On the other hand, the distal ends of a pair of upwardly projecting bosses 294 formed along the interior side 290 of the bottom panel 289 are received one each in the hardware pass through hole 281 and the hardware clearance notch 282 provided through the rigid body 275 of the valve trim retaining member 274. An elongate mounting hole 295 is provided through the bottom panel 289 of the bottom cover 287 and through each boss 294, as best shown in Figures 118 and 120. As also shown in Figure 120, the exterior end of each mounting bole is most preferably countersunk to enable flush insertion of the conventional mounting hardware for the bottom cover 287, such as, for example, screws 296 or the like, thereby ensuring that a user may comfortably grasp the handle body 151. As will be appreciated by those of ordinary skill in the relevant arts, provision of tire bosses 294 facilitates insertion of the screws 296 or like mounting hardware into threaded holes 286 for removably attaching the bottom cover 287 io the bottom 154 of the handle body 151, which, as shown in Figure 115, are provided in the bottom 154 or the handle body 151 a distance away from the interior side 290 of the bottom panel 289 of the bottom cover 287. Additionally, those of ordinary' skill in the relevant arts will recognize that for implementations where the bottom cover 287 is formed of a plastics or like material, the provision of the bosses 294 not only prevents cracking or breaking the bottom cover 287, but perhaps more importantly prevents flexing of the bottom cover 287 as may interfere with the cooperative arrangement between the bottom cover 287, the valve trim retaining member 274, the valve bodies 179a-179j, and the diluent selection valves 181a-181j. Referring again to Figure 120, it is noted that the next stage of assembly of the preferred implementation of the hand-held beverage dispenser 151 of the second embodiment - placement of the bottom cover 287 - is necessarily prefaced by first ensuring that the open topped cup 207 of the diluent selection valve 181a-18lj is for each valve unit 177a-177j correctly positioned in either the first operable state or the second operable state of the corresponding diluent selection valve 18la-181j so as to have properly selected either the first diluent of the second diluent. On the other hand, as previously discussed, if any one of the diluent selection valves 181a-181j has an out of place open topped cup 217, the implemented poka-yoke mechanism will prevent attachment to the handle body 151 of the bottom cover 287, thereby alerting the assembler to the misconfiguration. More importantly, the same result will obtain if a user of the hand-held beverage dispenser 150 has inadvertently misconfigured one of more diluent selection valves 181a-l 81j. If, for example, a misconfiguration occurs in the course of changing a diluent selection, accessing an interior space for cleaning or the like, or even satisfying a curiosity during a slow shift at the bar, the user will be alerted to the misconfiguration. In any case, with the diluent selection valves 18 la-18 Ij all correctly configured, the bottom cover 287 of the handle body 151 is positioned in place about the bottom 154 of the handle body 151, and retained in place with the screws 296, as shown, for example, in Figure 69, It should at this juncture be appreciated that with preferred implementation of the hand-held beverage dispenser 150 of the second embodiment of the present invention generally assembled to the foregoing stage, as has heretofore been described and is depicted in, for example, Figures 67-69, the implemented poka-yoke mechanism prevents any inadvertent change in the diluent selected for any diluent selection valve 181a-181j. More specifically, in any such hand-held beverage dispenser 150, in operable condition, the interposition of an upwardly projecting locking tab 291 into the arc of the travel of the stop tab 217 projecting from the lower exterior portion 216 of each open topped cup 207, as above described in detail, makes it impossible for any diluent selection valve 181a-181j to be inadvertently changed from its first operable state to its second operable state or any otherwise misconfigured state, or from its second operable state to its first operable state or any otherwise misconfigured state. In order for a user to operate a diluent selection valve 18la-18Ij -- that is, to change a selected diluent selection valve 181a-181j from its first operable state to its second operable state, or from its second operable state to its first operable state, the user must first disassemble the bottom cover 287 from the bottom 154 of the handle body 151. As wall be appreciated by those of ordinary skill in the relevant arts, this is readily accomplished by conventionally removing the screws 296, or other provided mounting hardware, and pulling away, as necessary, the bottom cover 287, as shown in Figure 120. With the relevant components of hand-held beverage dispenser in at least the stage of assembly depicted in Figure 116, the user may then change the selection for any one or more diluent selection valves 181 a-181j as desired, and as previously described with reference to Figures 112 and 116. In any case, once any desired change is made, and, preferably, a correct configuration for each diluent selection valve 181a-181j visually or otherwise verified, the user will then reassemble the bottom cover 287 with the bottom 154 of the handle body 151, as described above. Turning now to Figures 121-123, an exemplary button cap 264 as particularly suitable for attachment to the top end 230 of the cylindrical valve rod 228 of the exemplary flow control valve 180d, as the valve trim for the valve unit 177d is retained operably in place within the valve body 179d such that the top end 230 of the valve rod 228 protrudes through the upper seal 259 for the flow control valve 180d as retained within the flow control valve actuator orifice 183, as shown in Figure 127, and whereafter the attached button cap 264 will implement the ON-OFF flow control 1.53d for manual actuation by a user of the flow control valve 180d. As shown in the figures, the preferred implementations of the button cap 264 feature an overhanging side 265 or, depending on the shape of the button cap 264, overhanging sides 265. In any case, the overhanging sides 265 are provided to operate cooperatively with the top 182 of the valve body 179d to facilitate achieving a low profile valve control 153d, and also aids in preventing ingress to the button cap 264 and about the upper seal 259 and the for the flow control valve 180d and the top end 230 of the valve rod 228 of beverage fluids or like matter. As particularly shown in Figures 122-123, a snap ring 267 for dependently engaging the top of top end 230 of the valve rod 228 is formed within the interior space 266 of the button cap 264, as generally bounded by the overhanging sides 265. As shown in the figures, the implemented snap ring 267 comprises a pair of spaced tabs 268, each of which comprises a notch in the shape of a minor arc of a circle to cooperatively form a longitudinally oriented central aperture 269 between the tabs 268, Additionally, each of the tabs 268 has an interiorly projecting foot 270 formed about the bottom edge of the aperture, and sized, shaped and otherwise adapted to engage the keeper groove 231 provided about the top end 230 of the cylindrical valve rod 228, as previously described and particularly shown in Figures 94-96. Additionally, the implemented button cap 264 comprise a pair of oppositely disposed alignment and retention tabs 271, as will be understood further herein to cooperate with corresponding tab guide slots 303 formed within the top cover 300 for the handle body 151 for maintaining the button cap 264 on the top end 230 of the valve rod 228 and at the desired rotation about the valve rod 228, thereby ensuring that any printed matter applied to the top of the button cap 264 is properly viewable. As shown in Figures 124-126, an alternatively shaped button cap 272 is shown to comprise functionally identical structure within the interior space 266 bounded by the alternatively shaped overhanging sides 265. As shown in the figures, the alternatively shaped button cap 272 identically implements a snap ring 267 within the interior space 266 of the button cap 272, the snap ring 266 being formed of spaced tabs 268 forming a central aperture 269 with an interiorly projecting foot 270 adapted to engage the keeper groove 231 at the top end 230 of the valve rod 228. Alignment and retention tabs 271 are also provided about the alternatively shaped overhanging sides 265, but need not be identically sized or shaped as compared to the first described button cap 264. As shown in Figure 127, a button cap 164 is attached to the top end 230 of the protruding portion of the valve rod 228 by simply aligning the central aperture 269 with the central axis 206 of the targeted valve body 179d, and pressing the button cap 164 downward over and about the top end 230 of the valve rod 228, whereby contact with the top end 230 of the valve rod 228 will cause the spaced tabs 268 to flex slightly upward enabling central aperture 269 to receive the top end 230 of the valve rod 228 as the button cap continues downward until the interiorly projecting foot 270 engages the keeper groove 231 about the top end 230 of the valve rod 228 and the spaced tabs 268 snap back into position, with the button cap 264 initially secured in place. This process is repeated to apply a selected button cap 264 for each remaining flow control valve 180a-180c and 180e-180h, as shown in Figure 130. As also shown in Figure 130, flow control valves 180i-180j, which as previously described dispense a diluent only, form a subset 299 of flow controls for which it may be desired, as shown, to provide an alternatively shaped button cap 272 in order to more prominently distinguish the subset 299 of flow controls. hi any case, a top cover 300 is provided for the handle body 151 of the hand-held beverage dispenser 150 to conventionally enclose the tops 182 of the valve bodies 181a-181j and the various otherwise exposed elements of the implemented piping system 158, as best shown in Figures 128-130. Additionally, however, the provided top cover 300 is also specially adapted to operably retain m place each attached button cap 264, 272. In any case and as shown in the figures, the implemented top cover 300 is generally formed as a substantially planar single body manufacture having an aesthetically pleasing wing 306 extending symmetrically downward from each side of the top cover 300. A pair of downwardly projecting bosses 304 are provided on the bottom side 301 of the top cover 300 to provide the desired spacing between the bottom side 301 of the top cover 300 and the top 152 of the handle body 151, and to prevent flexing or breakage of the readily removable and replaceable top cover 301 during attachment to the handle body 151. A mounting hole 305 for the top cover 300 is provided through the top cover 300 into and through each provided boss 304. As best shown in Figures 130-131, the end of the mounting hole through the top cover 300 in particular is preferably countersunk to enable flush insertion of provided conventional mounting hardware for the top cover 300, such as, for example, screws 307 or the like, thereby ensuring that a user may comfortably grasp the handle body 151. As best shown in Figure 129, a button cap guide 302 for each implemented ON-OFF How control 153a~l53j projects downwardly from the bottom side 301 of the top cover 300, and is sized and shaped to allow passage of each particular button cap 264, 272 for which the particular top cover 300 is manufactured to support. As also best shown in Figure 129, each of the downwardly projecting button cap guides 302 includes a pair of tab guide slots 303, which are sized, shaped and disposed about each button cap guide 302 to operatively receive the alignment and retention tabs 271 as provided about the particular button cap 2.64, 272 for which the particular button cap guide 302. has been adapted to receive. It should be well noted at this juncture that the button caps 264, 272, in addition to traditional printed matter or coloring, may take any number of shapes, or be provided with any number of surface treatments, such as ridges, bumps, depressions or the like, and / or other visually, tactilely or similarly readily perceptible features, and changing the one button cap for another of a differing shape, or other characteristic, is a simple matter of removing the top cover 300, removing a first button cover 264 from the valve body 179a-179j for which the change is desired, affixing a second button cover 272 of the desired shape, and replacing the removed top cover 300 with a different top cover 300 having button cap guides 302 corresponding to the updated button cap configuration. The convenience with which such a change may be made is of particular utility in the connection with the hand-held beverage dispenser 150 as preferably implemented according to the second embodiment of the invention, where the on demand ability to select any available diluent for use with any valve unit 177a-177j only increases the likelihood that a user would change the beverage product dispensed through a particular valve unit 177a-177h which then also increases the likelihood that a user would also desire a change in shape of the button cap for a particular valve unit 177a-177h. In any case, with a button cap 264 attached to the top end 230 of each valve rod 228, as shown in Figure 130 to include alternatively shaped button caps 272 for the subset 299 of ON-OFF flow controls 153i-153j implemented for actuating the How control valves 180i-180j of the valve units 177i-177j configured to dispense a diluent only, the top cover is set in place on the top 152 of the handle body 151. As shown in Figure 131, button cap guides 302 projecting downwardly from the bottom side 301 of the top cover 300 conformingly receive each button cap 264, 272. Additionally, however, as each button cap 264, 272 is received within a corresponding button cap guide 302, the tab guide slots 303 disposed about the button cap guide 302 also capture the alignment and retention tabs 271 provided on the received button cap 264, 272. The top cover 300 is then conventionally attached to the top 152 by inserting the provided screws 307 through the mounting holes 305 through the top cover 300 and engaging the corresponding provided threaded holes 298 at the top 151 of the handle body 151, as shown in Figures 127 and 130. Referring now to Figures 132A-132E, 133A-133E, 134A-134E and 135A-135E, and various other figures as will be identified where they are found to be particularly instinctive, the four major exemplary states of operation of the representative valve unit I77d are shown and described. In particular the following discussions will describe in detail various flow paths through the valve unit 177d, fluid flows within or relating to the valve unit 177d, relationships between the components of the valve unit 177d and other components of the piping system 158 specifically and / or the hand-held beverage dispenser 150 or even external components generally, and user interactions with the valve unit 177d, where discussion of Figures 132A-132E will describe the valve unit 177d as configured to utilize the first diluent while the ON-OFF flow control 153d is not actuated; discussion of Figures 133A-133E will describe the valve unit 177d as configured to utilize the first diluent while the ON-OFF flow control 153d is actuated; discussion of 134A-134E will describe the valve unit 177d as configured to utilize the second diluent while the ON-OFF flow control 153d is not actuated; and discussion of Figures 135A-135E will describe the valve unit 177d as configured to utilize the second diluent while the ON-OFF flow control 153d is actuated. hi a first state of operation of the integrated valve unit 177d as depicted in Figures 132A-132E, the diluent selection valve 181d is configured to select a first diluent known to a user, which not necessarily known to the user is supplied under pressure to the hand-held beverage dispenser 150 through the first diluent inlet 160 at the rear end 157 of the handle body 151, for use in dispensing a beverage product associated by the user with ON-OFF flow control 153d, which also not necessarily known to the user actuates flow control valve 180d of valve unit 177d. As represented in the figures, however, the ON-OFF flow control 153d for actuation of flow' control valve 180d of valve unit 177d is not operated. If the desired first diluent is not already selected, the user may make the selection by-removing the bottom cover 287 from the handle body 151, as previously described in detail with reference to Figure 120, to expose the bottom 154 of the handle body 151 and the bottom side 222 of the closed bottom 221 of the open topped cup 207 of the diluent selection valve 181a-181d of each valve unit 177a-177j, as particularly shown in Figure 116 to be accessible for diluent selection through the provided selection access notches 278 in the rigid plate 275 of the valve trim retaining member 274. As well understood in light of the foregoing detailed disclosures, diluent selection valve 181d corresponds to ON-OFF flow control 153d. The user, however, will generally have little if any knowledge of the internal arrangements of the hand-held beverage dispenser 150, but will have been instructed that the correct user interface for selection of one diluent or the other is located at the bottom 154 of the handle-body 151, and directly aligned below and with the ON-OFF flow’ control 153d of interest. The flow control of interest 153d, however, is similarly likely known to the user only by some identifying indicium or the like corresponding to the beverage product to be dispensed in use of the ON-OFF flow control 153d of interest. In any case, the user will utilize the indicium of alignment 2.2 / 4 provided on bottom side 222 of the closed bottom 221 of the open topped cup 207, as also shown in Figure 92, in conjunction with the particular indicia of alignment 284 on the bottom side of the valve trim retaining member 274, as also shown in Figure 114, that are adjacent to and about the bottom side 222 of the closed bottom 221 of the open topped cup 207, to effect the desired selection, as previously described in detail with reference to Figures 112 and 116, In effecting the desired selection, however, the user will generally identify the desired diluent by indicia of alignment 284 on the bottom side of the valve trim retaining member 274, such as, for example, the letter W, which for the exemplary implementation indicates plain water, and the letter S, which for the exemplary implementation indicates soda. As depicted in the exemplary representation of Figure 116, plain water is the first diluent and soda is the second diluent, and the figure show's the first diluent, as properly selected. With the desired diluent selected, the user will then replace the bottom cover 287, as also previously described in detail wdth reference to Figure 120. In selecting the first diluent for use in dispensing a beverage product wdth ON-OFF flow' control 153d, the user or other party responsible for configuring the exemplary preferred implementation of the hand-held beverage dispenser 150 according to the second embodiment of the present invention, causes the horizontally oriented notch 212 through the upper edge 211 of the cylindrical side wall 208 of the open topped cup 207 of the diluent selection valve 181d to operably align wdth the first diluent inlet port 196 of the valve body 179d, as particularly shown in Figure 132B. As shown in Figures 132B and 132E, and also previously described, wdth reference to Figures 112 and 116, as the first operable state of the diluent selection valve 181d, this alignment of the horizontally oriented notch 212 with the first diluent inlet port 196 creates an open flow path through the diluent selection valve 181d between the supply branch 165d for the first diluent and the first diluent inlet port 196 of the valve body 179d, thereby allowing the first diluent to flow through the diluent selection valve fold for introduction of the first diluent into the lower chamber 192 of the valve body 179d. Simultaneously, however, selection of the first diluent for use in dispensing a beverage product with ON-OFF flow control 153d also causes an intact portion of the side wall 208 of the open topped cup 207 of the diluent selection valve fold to operably align with the second diluent inlet port 197 of the valve body 179d, as also particularly shown in Figure 132B. As shown in Figures 132B and 132E, this alignment of an intact portion of the side wall 208 with the second diluent port 197 creates a flow- blocking gate within the diluent selection valve 18Id between the supply branch 168d for the second diluent and the second diluent inlet port 197 of the valve body 179d, thereby preventing flow of the second diluent through the diluent selection valve fold. and introduction of the second diluent into the lower chamber 192 of the valve body 179d. In the first state of operation of the integrated valve unit 177d, as previously defined and also depicted in Figures 132A-132E, a beverag...
