[0004] This disclosure provides, and is intended to provide, an improved fluid material distribution system disclosed herein.

[0005] Accordingly, according to one aspect, a dispensing mechanism is provided for a bottle or canister configured to contain a fluid material. The dispensing mechanism includes a lever, actuation of which causes a plunger to slidably engage the inner wall of the bottle and travel in a first direction toward an outlet of the bottle to dispensing fluid material from the outlet. The dispensing mechanism includes a dispensing stop connected to a cap and positioned at a defined location along the travel path of the lever. The distance traveled by the lever is limited by direct contact between the teeth of the lever and the dispensing stop, thereby limiting the distance traveled by the plunger to restrict the dispensing amount of fluid material to a corresponding defined share. When actuated, the teeth subject the dispensing stop to a load. The shape of the teeth is determined to facilitate the dispersion of this load in order to inhibit damage / wear and / or deformation of the cap.

[0006] According to another aspect, a dispensing mechanism for a bottle or canister configured to contain a fluid material is further provided. The dispensing mechanism includes a lever, actuation of which causes a plunger to slidably engage an inner wall of the bottle and travel in a first direction toward an outlet of the bottle to dispensing fluid material from the outlet. The lever includes teeth that project outwardly a defined distance along the travel path of the lever. The teeth include a first end portion adjacent to a first side of the lever and a second end portion adjacent to a second side of the lever. The dispensing mechanism includes a dispensing stop at a defined position along the travel path of the lever. The distance traveled by the lever is limited by direct contact between the teeth and the dispensing stop located within the travel path, thereby limiting the distance traveled by the plunger to restrict the dispensing amount of fluid material to a corresponding defined share.

[0007] According to another aspect, a dispensing mechanism for a bottle or canister configured to contain a fluid material is also provided. The dispensing mechanism includes a cap for attachment to one end of the bottle. The dispensing mechanism includes an operating lever pivotally connected to the cap via a metal bearing pin. Actuation of the operating lever causes a plunger to slidably engage the inner wall of the bottle and travel toward the bottle's outlet to discharge the fluid material from the outlet. The dispensing mechanism includes a dispensing stop at a defined position along the travel path of the operating lever. The distance traveled by the operating lever is limited by contact between the operating lever and the dispensing stop located within the travel path, thereby limiting the distance traveled by the plunger to restrict the discharge of the fluid material to a corresponding defined portion.

[0008] According to another aspect, a dispensing mechanism for a bottle or canister configured to contain a fluid material is further provided. The dispensing mechanism includes a cap for attachment to one end of the bottle. The dispensing mechanism includes an operating lever pivotally coupled to the cap via a metal member. For example, the metal member may include a butt bolt, a fastener, and a cylindrical nut shaped to be threaded onto the fastener, a spring, a cotter pin, a U-shaped clamp, or a set of spring-loaded plungers. Actuation of the operating lever causes the plungers to slidably engage the inner wall of the bottle and travel toward the bottle's outlet to discharge the fluid material from the outlet. The dispensing mechanism includes a dispensing stop at a defined position along the travel path of the operating lever. The distance traveled by the operating lever is limited by contact between the operating lever and the dispensing stop located within the travel path, thereby limiting the distance traveled by the plunger to restrict the discharge of the fluid material to a corresponding defined share.

[0009] According to another aspect, a dispensing mechanism for a bottle or canister configured to contain a fluid material is also provided. The dispensing mechanism includes a lever. Actuation of the lever causes a plunger to slidably engage the inner wall of the bottle and travel in a first direction toward the bottle's outlet to dispensing fluid material from the outlet. The dispensing mechanism includes a dispensing stop at a defined location along the travel path of the lever. The distance traveled by the lever is limited by contact between the lever and the dispensing stop located within the travel path, thereby limiting the distance traveled by the plunger to restrict the dispensing amount of fluid material to a corresponding defined portion. The dispensing mechanism includes a handle aligned with the first direction. The lever is pivotally coupled to the handle and is at least partially received within the handle. The shapes of the lever and handle are designed to facilitate cleaning without requiring disassembly.

[0010] According to yet another aspect, a dispensing mechanism for a bottle or canister configured to contain a fluid material is provided. The dispensing mechanism includes a lever operable between an idle position and an engaged position, the engaged position causing a plunger to slidably engage the inner wall of the bottle and travel in a first direction toward the bottle's outlet to discharge the fluid material from the outlet. The dispensing mechanism includes a plate having a plate orifice. The plate is movable between an upper position and a lower position. The dispensing mechanism includes an elongated member passing through the plate orifice. The elongated member is operatively coupled to the plunger and extends along the first direction. Pivoting movement of the lever from the idle position to the engaged position causes the plate to engage with the elongated member and move from the upper position to the lower position in the first direction, wherein the plate and the elongated member thereby cause the plunger to travel in the first direction. The dispensing mechanism includes a cap for attachment to the end of the bottle opposite to the fluid outlet. The lever is pivotally coupled to the cap. The cap encloses the interior. The interior of the plate and the cap are in fluid communication.

[0011] According to another aspect, a dispensing mechanism for a bottle or canister configured to contain a fluid material is further provided. The dispensing mechanism includes a lever operable between an idle position and an engaged position. This causes a plunger to slidably engage the inner wall of the bottle and travel in a first direction toward the bottle's outlet to discharge the fluid material from the outlet. The dispensing mechanism includes a plate having a plate orifice. The plate is movable between an upper position and a lower position. The dispensing mechanism includes an elongated member passing through the plate orifice. The elongated member is operatively coupled to the plunger and extends along the first direction. Pivoting movement of the lever from the idle position to the engaged position causes the plate to engage with the elongated member and move from the upper position to the lower position in the first direction, wherein the plate and the elongated member thereby cause the plunger to travel in the first direction. The dispensing mechanism includes a cap for attachment to the end of the bottle opposite to the fluid outlet. The lever is pivotally coupled to the cap. The lever, plate, and cap are operatively connected together in a manner that facilitates cleaning.

[0012] According to another aspect, a dispensing mechanism for a bottle or canister configured to contain a fluid material is also provided. The dispensing mechanism includes a lever operable between an idle position and an engaged position. This causes a plunger to slidably engage the inner wall of the bottle and travel in a first direction toward the bottle's outlet to discharge the fluid material from the outlet. The dispensing mechanism includes a plate having a plate orifice. The plate is movable between an upper position and a lower position. The dispensing mechanism includes an elongated member passing through the plate orifice. The elongated member is operatively coupled to the plunger and extends along the first direction. Pivoting movement of the lever from the idle position to the engaged position causes the plate to engage with the elongated member and move from the upper position to the lower position in the first direction, wherein the plate and the elongated member thereby cause the plunger to travel in the first direction. The dispensing mechanism includes a cap for attachment to the end of the bottle opposite to the fluid outlet. The cap has an inner surface that is substantially exposed to facilitate cleaning.

[0013] According to yet another aspect, a dispensing mechanism for a bottle or canister configured to contain a fluid material is further provided. The dispensing mechanism includes a lever operable between an idle position and an engaged position. This causes a plunger to slidably engage the inner wall of the bottle and travel in a first direction toward the bottle's outlet to discharge the fluid material from the outlet. The dispensing mechanism includes a plate having a plate orifice. The plate is movable between an upper position and a lower position. The dispensing mechanism includes an elongated member passing through the plate orifice. The elongated member is operatively coupled to the plunger and extends along the first direction. Pivoting movement of the lever from the idle position to the engaged position causes the plate to engage with the elongated member and move from the upper position to the lower position in the first direction, wherein the plate and the elongated member thereby cause the plunger to travel in the first direction. The dispensing mechanism includes a cap for attachment to the end of the bottle opposite to the fluid outlet. The cap has a downward-facing inner surface that is substantially exposed to facilitate cleaning.

[0014] According to another aspect, a dispensing mechanism for a bottle or canister configured to contain a fluid material is also provided. The dispensing mechanism includes a lever operable between an idle position and an engaged position. This causes a plunger to slidably engage the inner wall of the bottle and travel in a first direction toward the bottle's outlet to discharge the fluid material from the outlet. The dispensing mechanism includes a plate having a polygonal orifice. The plate is movable between an upper position and a lower position. The dispensing mechanism includes an elongated member passing through the orifice. The elongated member is operatively coupled to the plunger and extends along the first direction. Pivoting movement of the lever from the idle position to the engaged position causes the plate to engage with the elongated member and move from the upper position to the lower position in the first direction, wherein the plate and the elongated member thereby cause the plunger to travel in the first direction. The external shape of the elongated member is polygonal.

[0015] According to another aspect, a dispensing mechanism for a bottle or canister configured to contain a fluid material is also provided. The dispensing mechanism includes a lever operable between an idle position and an engaged position. This causes a plunger to slidably engage the inner wall of the bottle and travel in a first direction toward the bottle's outlet to discharge the fluid material from the outlet. The dispensing mechanism includes a first plate having plate orifices extending therethrough. The dispensing mechanism includes a spring-loaded second plate spaced apart from the first plate. The second plate has plate orifices and is movable between an upper position and a lower position. The dispensing mechanism includes an elongated member passing through these plate orifices. The elongated member engages with the plunger and extends along the first direction. The first plate is configured to inhibit linear movement of the elongated member opposite to the first direction. Pivoting movement of the lever from the idle position to the engaged position causes the second plate to engage with the elongated member and move from the upper position to the lower position in the first direction, wherein the second plate and the elongated member thereby cause the plunger to travel along the first direction.

[0016] According to another aspect, there is also a dispensing mechanism for a bottle or canister configured to contain a fluid material. This dispensing mechanism includes a lever operable between an idle position and an engaged position. The latter causes a plunger to slidably engage the inner wall of the bottle and travel in a first direction toward the bottle's outlet to discharge the fluid material from the outlet. The dispensing mechanism includes a pair of axially spaced plates. The dispensing mechanism includes an elongated member passing through corresponding orifices of these plates. The first plate is spring-biased to inhibit translation of the elongated member opposite to the first direction. The second plate is neutrally spring-biased to allow the elongated member to pass freely therethrough until the lever moves toward the engaged position, causing the elongated member to engage the plunger and bias the plunger to move along the first direction.

[0017] According to another aspect, a dispensing mechanism for a bottle or canister configured to contain a fluid material is further provided. The dispensing mechanism includes a lever. Actuation of the lever causes a plunger to slidably engage the inner wall of the bottle and travel in a first direction toward the bottle's outlet to dispensing fluid material from the outlet. The dispensing mechanism includes a handle toward which the lever is actuated. The handle includes at least one dispensing stop at a defined position along the travel path of the lever. The distance traveled by the lever is limited due to direct contact between the lever and the dispensing stop located within the travel path, thereby limiting the distance traveled by the plunger to restrict the dispensing amount of fluid material to a corresponding defined share.

[0018] According to another aspect, a dispensing mechanism for a bottle or canister configured to contain a fluid material is also provided. The dispensing mechanism includes a lever, actuation of which causes a plunger to slidably engage the inner wall of the bottle and travel in a first direction toward the bottle's outlet to dispensing fluid material from the outlet. The dispensing mechanism includes a handle toward which the lever is actuated. The lever includes at least one dispensing stop having a defined shape, wherein the distance traveled by the lever is limited by direct contact between the dispensing stop and a portion of the handle located within the travel path of the lever. This thereby limits the distance traveled by the plunger to restrict the dispensing amount of fluid material to a corresponding defined share.

[0019] According to another aspect, a dispensing mechanism for a bottle or canister configured to contain a fluid material is also provided. The dispensing mechanism includes a cap for attachment to one end of the bottle. The dispensing mechanism includes an operating lever pivotally coupled to the cap. Actuation of the operating lever causes a plunger to slidably engage the inner wall of the bottle and travel toward the bottle's outlet to discharge the fluid material from the outlet. The operating lever includes an elongated and / or enlarged side portion and / or rear portion and / or at least one rib. The dispensing mechanism includes a handle operatively connected to the cap, and the operating lever is actuated toward the handle. The distance traveled by the operating lever is limited by direct contact between the elongated and / or enlarged side portion and / or rear portion and / or at least one rib of the operating lever and a portion of the cap and / or handle located within the travel path of the operating lever. This thereby limits the distance traveled by the plunger to restrict the discharge of the fluid material to a correspondingly defined share.

[0020] According to another aspect, a dispensing mechanism for a bottle or canister configured to contain a fluid material is also provided. The dispensing mechanism includes a cap for attachment to one end of the bottle. The dispensing mechanism includes a lever pivotally coupled to the cap, wherein actuation of the lever causes a plunger to slidably engage the inner wall of the bottle and travel toward an outlet of the bottle to discharge fluid material from the outlet. The lever includes a first of a concave portion or a convex portion partially facing a handle. The dispensing mechanism includes a handle operatively connected to the cap, and the lever is actuated toward the handle. The handle includes a second of the concave portion and the convex portion, at least partially facing the lever. When the lever is actuated, the distance traveled by the lever is limited due to the direct contact between the concave and convex portions, thereby limiting the distance traveled by the plunger to restrict the discharge of fluid material to a corresponding defined share.

[0021] It should be emphasized that this utility model relates to all combinations of the above features, even if these combinations are described in different embodiments. Attached Figure Description

Detailed Implementation

[0025] In the following description, specific details are set forth in order to provide a more thorough understanding of the present invention. However, the present invention may be practiced without these details. In other instances, well-known elements have not been shown or described in detail to avoid unnecessarily obscuring the present invention. Accordingly, the description and drawings should be regarded as illustrative rather than restrictive.

[0026] As mentioned above, U.S. Patent No. 8,511,520 by van Wijke et al., filed with the U.S. Patent and Trademark Office on February 23, 2012, discloses a fluid material distribution system, the contents of which are incorporated herein by reference.

[0027] Refer to the attached diagram and first refer to... Figure 1 An improved fluid material distribution system 30 is shown. The system includes a top 32, a bottom 34 spaced apart from the top, a front 36, a rear 38 spaced apart from the front, a left side 40, and a right side 42 spaced apart from the left side.

[0028] As in Figure 2 As seen in the image, the fluidized material distribution system 30 includes a cylinder 43. The cylinder includes a bottle 44. In this non-limiting embodiment, the bottle is hollow and its external shape is generally cylindrical; however, the latter is not strictly required. Figure 3 As seen in the image, bottle 44 has an open end or top 44A, a bottom 44B spaced apart from its top, and an inner sidewall 44C extending between its top and bottom. The bottle has an outer surface 44D extending between its top 44A and bottom 44B. In this non-limiting example, the outer surface of bottle 44 has measuring marks 44E. In this non-limiting example, the bottle includes one or more channels 44F and 44G formed in the region of the inner sidewall 44C of the bottle. Bottle 44 has an interior 45 enclosed by its inner sidewall 44C. The interior of the bottle is in fluid communication with channels 44F and 44G, wherein the inner diameter has a draft angle or taper; however, neither the former nor the latter is strictly required. Bottle 44 extends along a longitudinal axis 46, which passes through the center of the bottle and extends between the top 44A and bottom 44B of the bottle. Figure 9 As seen in the image, the bottle is shaped to receive fluid material 48 therein and is configured to selectively dispense or discharge fluid material therefrom.

[0029] refer to Figure 2 In this non-limiting example, cylinder 43 includes a first cap or discharge cap 50. The discharge cap may be referred to as a first or lower cylinder cap or bottle cap. Return to Reference Figure 9The discharge cap 50 includes a sleeve portion 50A extending about axis 46. The discharge cap is configured to be operatively coupled to the bottom 44B of the bottle 44 via its sleeve portion: in this non-limiting example, the discharge cap is threaded to the bottle 44 via an external thread 44H adjacent to the bottom of the bottle, wherein the external thread is threadedly coupled to the internal thread 50B of the discharge cap.

[0030] The discharge cap 50 includes a flange portion 50C that is coupled to and extends radially / laterally inward from a sleeve portion 50A of the discharge cap. In this example, the flange portion is annular, with an orifice 50D extending centrally through it. Figure 1 As seen in this non-limiting example, the discharge cap 50 includes a plurality of longitudinally extending protrusions or legs 52A, 52B, and 52C. The legs extend circumferentially about axis 46, with recessed portions located therebetween; however, this is not strictly required. The fluidized material distribution system 30 is configured to rest in an upright position so that the legs 52A, 52B, and 52C of the discharge cap 50 extend substantially along and about this axis. In this non-limiting embodiment, the sleeve portion 50A, the flange portion 50C, and the legs of the discharge cap are integrally connected together to form a single unit.

[0031] As in Figure 2 As seen in the image, cylinder 43 includes a valve, in this example an outlet valve 54. A discharge cap 50 is configured to house the valve thereon. In this non-limiting example, it can thus be said that bottle 44 includes an outlet adjacent to its bottom 44B, where the bottom of the bottle is closed elsewhere. Alternatively or additionally, it can be said that the bottle's outlet includes valve 54. The valve is made of an elastomer (in this non-limiting example, flexible vulcanized silicone rubber). Figure 9 As seen in this non-limiting example, valve 54 includes a sleeve portion 54A extending along and about axis 46, and a flange portion 54B coupled to and extending radially / laterally outward from the sleeve portion. The sleeve portion of the valve extends axially downward through an orifice 50D of the discharge cap 50, and the flange portion of the valve is configured to abut against and / or be received by the flange portion of the discharge cap. Valve 54 is configured to be normally closed to inhibit the flow of fluid material 48 through it. Many different types of valves can be provided, such as one or more valves described in Fisher's U.S. Patent Application No. 18 / 645059, filed April 24, 2024, with the U.S. Patent and Trademark Office, the disclosure of which is incorporated herein by reference.

[0032] As in Figure 9 As seen in the image, bottle 44 in this non-limiting example includes a first annular stop, which in this non-limiting example is a first annular open portion 44I adjacent to its external thread 44H. From Figure 9 From this perspective, the first opening portion opens radially outward in a downward direction. The shape of the first opening portion 44I is designed to suppress excessive rotation of the discharge cap 50. This also allows for use in the case of larger orifice valves. Figure 12 The valve 54, which is in the form of a silicone rubber gasket, prevents the valve from being over-tightened and rotated to maintain the desired compression, and also serves to prevent / minimize compression deformation.

[0033] As in Figure 2 As seen in the image, cylinder 43 includes a plunger 56. The plunger is made of a polymer, which in this non-limiting example is a mixture primarily of low-density polyethylene and polyoxymethylene. (Reference) Figure 10 The plunger is configured to apply a compressive force to the fluid material 48 as it travels along a first direction 58 through the interior 45 of the bottle 44. This causes the valve 54 to be actuated or moved toward a position at least partially open, thereby facilitating the discharge of the fluid material through it, as indicated by numeral 48A. The following are non-limiting embodiments of achieving this function.

[0034] In this example, the plunger 56 includes two spaced-apart flexible flanges, in this case an upper flange 56A and a lower flange 56B, which are configured to frictionally engage with the inner wall 44C of the bottle 44 as the plunger moves along a first direction 58. One of the flexible flanges (the upper flange in this non-limiting example) extends towards the sidewall of the bottle at an angle and opposite to the first direction. The upper flange 56A is thus configured to exhibit reduced compliance when subjected to a force opposite to the first direction 58. The reduced compliance relative to the compliance of the upper flange during travel in the first direction facilitates frictional engagement between the upper flange and the inner wall 44C, thereby substantially holding the plunger 56 in place against forces oriented opposite to the first direction. Thus, friction of the plunger caused by engagement with the inner wall 44C of the bottle 44 prevents or inhibits translation of the lever 90 until actuated via the lever 68 and the plate 80. Figure 3 The channels 44F and 44G of the bottle 44 seen in the image are not occupied by the plunger, and when the plunger is brought into contact with the fluid material, it helps air to escape from the bottle and from around the plunger, thereby preventing unintentional leakage of the fluid material during the assembly of the fluid material distribution system 30.

[0035] Still referencing Figure 3 The fluid material distribution system includes a distribution mechanism 60. In some embodiments, a plunger may be considered part of the distribution mechanism; however, this is not strictly required.

[0036] As in Figure 5 As seen in the image, the dispensing mechanism 60 includes a second cap or dispensing cap 62. The dispensing cap may be referred to as a second bottle cap or an upper bottle cap. (Reference) Figure 3 and Figure 8 The dispensing cap 62 is configured for attachment to the open top 44A of the bottle 44: in this non-limiting example, the dispensing cap has Figure 8 The bayonet thread seen in the image is 64A. This bayonet thread is screwed to... Figure 3 The pin 64B is located at the top of the bottle, as seen in the image. (Return to reference) Figure 5 The dispensing cap has a sleeve portion 62A extending about an axis 46 and a top portion 62B coupled to and extending radially / laterally inwardly from the sleeve portion. In this non-limiting example, the top portion of the dispensing cap 62 is rounded and has an aperture 63 extending through it. In this non-limiting embodiment, the sleeve portion 62A and the top portion 62B of the dispensing cap are integrally joined together to form a single unit. In this example, the dispensing cap 62 includes gripping notches 62C spaced circumferentially along the outer side of its sleeve portion 62A to facilitate gripping. In this example, the dispensing cap includes a mark 62D along the outer side of the sleeve portion, and this mark is configured to interact with the bottle when the dispensing cap is fully coupled to / locked with the bottle. Figure 1 The bottle 44, as seen in the image, is aligned with the mark 44E. The sleeve portion and top portion of the dispensing cap 62 define... Figure 8 The dispensing cap 62E, as seen herein, serves to at least partially enclose that interior. A bayonet thread 64A is in fluid communication with the interior of the dispensing cap. The dispensing mechanism 60, as described herein, is configured for backward compatibility with other components.

[0037] As in Figure 9 As seen in the image, bottle 44 in this non-limiting example includes a second annular stop, which in this non-limiting example is a second annular open portion 44J. From Figure 9 From the perspective of [the point of view], the second opening portion opens radially outward in the upward direction. The second opening portion 44J is positioned adjacent to the sleeve portion 62A of the dispensing cap 62.

[0038] The shape of the dispensing cap 62 is designed to facilitate its cleaning. The following are non-limiting embodiments that achieve this functionality. (As in...) Figure 8 As seen in the image, the dispensing cap 62 has an open bottom 62F, the inner surfaces of which are substantially exposed for ease of cleaning. These surfaces include the inner surface or inner surface 62A' of the sleeve portion 62A of the dispensing cap and the inner surface or downward-facing inner surface 62B' of the top portion 62B of the dispensing cap. The downward-facing inner surface of the top portion of the dispensing cap 62 is substantially exposed.

[0039] refer to Figure 5The dispensing mechanism 60 includes a handle 66. The handle is elongated and has an upper end or top 66A and a lower end or bottom 66B spaced apart from its top. The bottom of the handle 66 is coupled to and extends upward from the top portion 62B of the dispensing cap 62. In this example, the bottom 66B of the handle is at least partially bracket-shaped. In this non-limiting embodiment, the handle 66 is integrally connected to the dispensing cap 62 to form a single unit; however, this is not strictly required. In this example, the top 66A of the handle is at least partially closed. In this non-limiting example, the handle 66 includes a flange 66C along its top. In this non-limiting embodiment, the flange is laterally extending and semi-circular. Reference Figure 10 The flange 66C is configured to rest on the user's hand, allowing the dispensing mechanism 60 to be held in a non-grip manner, with the user's hand positioned between the flange and the outlet valve 54. The handle 66 extends along the longitudinal axis 46 of the bottle 44 between its top 66A and bottom 66B. In this non-limiting example, the handle extends away from the bottle along a longitudinal axis aligned with a first direction 58 and substantially passing through the center of the bottle. Figure 5 As seen in the image, the handle 66 has a pair of spaced-apart sides 67A and 67B extending between its top 66A and bottom 66B.

[0040] The shape of the handle 66 is designed to facilitate cleaning. The following are non-limiting embodiments of achieving this functionality. See reference... Figure 5 and Figure 10 As seen in this example, the handle 66 opens continuously along its inner side 66D from its top 66A to its bottom 66B. The handle defines a continuous path or open interior 66E between its bottom and top. In this non-limiting example, the lateral cross-section of the handle 66 is C-shaped.

[0041] As in Figure 3 As seen in the image, the distribution mechanism 60 includes a lever 68. (Reference) Figure 6 The joystick is elongated, having an upper end or open top 68A and a lower end or bottom 68B spaced apart from its top. The joystick 68 can... Figure 9 The non-actuated or idle positions seen in the image are... Figure 10 The operation occurs between the actuation or engagement positions as seen in the image. Return to reference. Figure 6 The lever 68, when in its disengaged or idle position, extends along the longitudinal axis 73 between its bottom and top. The longitudinal axis of the lever is angularly separated from the longitudinal axis 46 of the bottle by an angle α, which is acute in this example. As the lever moves toward axis 46, actuation of the lever 68 in direction 71 reduces this angle. The lever has a first side or left side 68C and a second side or right side 68D spaced apart from its left side.

[0042] The shape of the lever 68 is designed to facilitate its cleaning. The following is a non-limiting embodiment of how this functionality is achieved. In this example, the lever 68 is continuously open and defines an open interior 68E along its inner side 68F from its top 68A to its bottom 68B. Therefore, the lever defines a continuous path between its bottom and top. In this non-limiting example, the lateral cross-section of the lever 68 is C-shaped. (As in...) Figure 7 As seen in this non-limiting embodiment, the open interior 68E of the joystick faces the open interior 66E of the handle 66. Therefore, the joystick 68 defines a continuously open space in the direction facing the handle between its top 68A and bottom 68B, and thus it can be said that the handle defines a continuously open space in the direction facing the joystick between its top 66A and bottom 66B.

[0043] The lever and dispensing cap 62 are operatively connected together in a manner that facilitates their cleaning. In this example, the base 68B of the lever 68 is pivotally connected to the dispensing cap via an elongated metal member or fastener assembly about a fulcrum 68G: this may include a fastener and a cylindrical nut shaped to be threadedly connected to the fastener, and / or may include a sex bolt 70 extending through a laterally extending hole or orifice 70A in this non-limiting example. As another alternative, a barrel screw / nut, or a spring, cotter pin, U-shaped clamp, and / or a set of spring-loaded plungers may be provided. One or more of these features may be referred to as a bearing pin and / or alternatively, in other embodiments, the lever 68 may be connected to the dispensing cap 62 via a bearing pin. Thus, in this example, the fulcrum 68G is aligned or coaxial with the sex bolt 70. The sex bolt extends between the two sides 67A and 67B of the handle 66 and may be referred to as a full-length fastener or connector. In this non-limiting example, the sex bolt 70 and / or the bearing pin are made of stainless steel. Such a configuration, with its full-length mating bolts and / or stainless steel shaft, and the fluid material distribution system 30 as described herein, can therefore comprise a more robust and wear-resistant system. This contrasts with the system in U.S. Patent No. 8,511,520, which discloses plastic rotating pins, which, for example, may be damaged over time due to strong use and / or improper assembly.

[0044] Return to reference Figure 6 The joystick 68 includes a hand-actuated portion 68H extending from its top 68A toward its bottom 68B and a plate contact portion 68I extending from its bottom toward its top. The hand-actuated portion and the plate contact portion of the joystick are located on opposite sides of the fulcrum 68G. Figure 6The hand-actuated portion 68H of the joystick, as seen in the diagram, is longer than the plate contact portion 68I of the joystick, in order to provide mechanical advantages when the joystick is moved from its idle position or actuated to its engaged position.

[0045] As in Figure 7 As seen in the diagram, the handle 66 is therefore operatively connected to the joystick 68. Thus, it can be said that the joystick is pivotally connected to the handle and / or pivotally connected relative to the handle. The shapes of the joystick 68 and the handle 66 are designed to facilitate cleaning without requiring disassembly.

[0046] The joystick 68 includes a protrusion, in this example, a tooth 72. This tooth is configured to extend outward a defined distance DT along the joystick's travel path 74. In this non-limiting example, the tooth 72 is adjacent to or near the bottom 68B of the joystick 68. In this example, the tooth is configured to extend outward from the joystick. The hand-actuated portion 68H of the joystick 68 includes a sub-portion 68H' adjacent to the bottom 68B of the joystick and configured to abut against and extend flush with the top portion 62B of the dispensing cap 62 in the joystick's idle position. Figure 10 In the actuated position of the joystick seen in the image, the bottom and sub-parts of the joystick are angled relative to the top part of the distribution cap.

[0047] The joystick 68 is configured to be at least partially received within the handle 66 when actuated. Moving the joystick from... Figure 9 The idle space seen in the middle caused to Figure 10 The engagement position seen in the diagram causes the plunger 56 to slidably engage along the inner wall 44C of the bottle 44 and travel in a first direction 58 toward the bottle's outlet valve 54 to discharge fluid material 48 therefrom, as indicated by numeral 48A. The distance the plunger travels in the first direction increases with the distance the lever travels from the idle position to the engaged position. The plunger 56 is configured to frictionally engage the inner wall 44C of the bottle 44 to a degree sufficient to hold the plunger substantially in place against forces opposite to the first direction, said forces being applied by the dispensing mechanism 60 due to the pivoting return movement of the lever 68.

[0048] refer to Figure 4 The dispensing mechanism includes a dispensing mechanism 76. The dispensing mechanism is configured to move the lever 68 from... Figure 9 The idle space seen in the middle Figure 10 The distance traveled by the plunger 56 at its engagement position is limited to a predetermined amount, thereby limiting the distance traveled by the plunger 56 to limit the discharge of the fluid material 48 to a corresponding predetermined share 48A. The following are non-limiting embodiments for achieving this function.

[0049] refer to Figure 4The dividing mechanism 76 is configured to limit the distance traveled by the joystick to a predetermined amount, wherein in this non-limiting embodiment, the dividing mechanism includes one or more (in this example, multiple) dividing stops, in this non-limiting example, a first dividing stop 76A and an alternative or second dividing stop 76B. Figure 4 From this perspective, the second dividing stop is axially / longitudinally spaced from the first dividing stop and, in this example, below the first dividing stop. In other embodiments, additional dividing stops may also be present. In this non-limiting example, dividing stops 76A and 76B are coupled to and are part of the dividing ring 76C, which can be said to be part of the dispensing mechanism 60 (and / or its dividing mechanism 76). The dividing ring is operatively connected to Figure 9 The joystick 68 seen in the image can be rotated relative to it.

[0050] In this non-limiting embodiment, the dividing ring 76C is rotatably and slidably coupled to the dispensing cap 62 about axis 46, in this non-limiting example via a mortise and tenon connector 78. In this non-limiting example, the mortise and tenon connector includes: a radially / laterally extending flange 78A coupled to the first of the dividing ring and the dispensing cap (the dividing ring in this example), adjacent to its bottom; and an annular recess 78B or groove, which is part of the second of the dividing ring and the dispensing cap (the dispensing cap in this example), between the sleeve portion 62A and the top portion 62B of the dispensing cap. Rotation of the dividing ring 76C allows it to be replaced with a second dividing stop 76B. Figure 4 The first segment stop 76A seen in the middle, thus making Figure 10 The joystick 68 seen in the image can travel a greater distance, for example, if a larger segment size is desired.

[0051] When engaged / actuated, the lever 68 loads the dispensing ring 76C (and its corresponding dispensing stop 76A) via teeth 72. The distance traveled by the lever 68 is limited by the direct contact between the teeth and the corresponding dispensing stop located within the travel path 74. This limits the distance traveled by the plunger 56 toward the valve 54, and thus limits the discharge of the fluidized material 48 to the corresponding defined portion 48A. Therefore, the given / selected dispensing stop 76A defines the engaged position of the lever 68. The dispensing stop is configured to maintain its defined position relative to the dispensing mechanism 60. The dispensing stop 76A is available in various configurations. Figure 4 The alternative segmented stop 76B seen in the diagram is replaced by an alternative defined position placed along the travel path of the control lever. This alternative segmented stop defines an alternative engagement position different from the original engagement position, thereby limiting the discharge of the fluidized material to different defined shares. Figure 10 During operation of the lever 68 as seen in the diagram, the portion stops 76A and 76B are in a fixed position relative to the distribution cap 62. According to one non-limiting embodiment, the defined portion 48A comprises up to (and includes) one ounce, in another non-limiting example it is greater than one ounce, and in yet another non-limiting embodiment it is between one and two ounces.

[0052] The shape of the teeth 72 of the lever 68 is designed to facilitate the distribution of load on the dividing ring 76C (and / or its corresponding dividing stop 76A) in order to inhibit damage and / or wear and / or deformation. The following are non-limiting embodiments for achieving this function.

[0053] As in Figure 6 As seen in the image, tooth 72 includes a first end portion 72A and a second end portion 72B spaced apart from the first end portion. In this example, the first end portion of the tooth is adjacent to the left side 68C of the lever 68, and in this example, the second end portion of the tooth is adjacent to the right side 68D of the lever. Tooth 72 extends along a longitudinal axis 75. In this non-limiting example, the top and front or front portion of the tooth is curved, in which case it includes an outwardly convex shape / surface 72C. In this non-limiting example, the lateral section of tooth 72 is generally or substantially triangular. In this non-limiting example, each end portion 72A and 72B of the tooth is at least partially longitudinally and laterally convex outward. In this non-limiting embodiment, the shape of each end portion of tooth 72 is generally or substantially quarter-spherical. The tooth selectively engages via a bearing surface 72D. Figure 10 The segmented stop component 76A seen in the image. (Return to reference) Figure 6 In this embodiment, the bearing surface of the tooth 72 is planar and elongated. In this non-limiting example, the bearing surface 72D of the tooth is rectangular in shape.

[0054] Tooth 72 has a length LT parallel to its longitudinal axis 75 and extending between its end portions 72A and 72B. The length of the tooth is generally and / or substantially perpendicular to... Figure 7 The path 74 seen in the image extends. In this example, Figure 6 The length LT of tooth 72 seen in the image is greater than Figure 7 The defined distance DT seen in the image. In this non-limiting embodiment, the length of the tooth is greater than the length of the corresponding segmented stop, as shown by... Figure 4 The length of the segmented stop 76A seen in the image is LS; however, this is not a strict requirement. (Return to reference) Figure 6The tooth 72 is configured to be enlarged and / or thus include an enlarged bearing surface 72D. The tooth, which may be referred to as an enlarged tooth, is configured to distribute the load across the dividing ring 76C, thereby reducing and / or suppressing localized deformation thereon and / or on it. Compared to the system shown in U.S. Patent No. 8,511,520, the bearing surface 72D of the tooth 72 of the distribution mechanism 60 described herein may be at least doubled according to one embodiment, increased by at least 75% according to another non-limiting embodiment, and increased by 78% according to yet another non-limiting embodiment.

[0055] Therefore, it can be said that the dispensing mechanism 60 (and / or its teeth and dispensing rings) as described herein includes a more robust solution that suppresses the variation of the dispensing of the fluid material over time (which could otherwise be caused by wear, fatigue, deformation, etc.), thereby reducing wear and tear on the dispensing ring 76C. Figure 9 The lever 68 and teeth 72 seen herein are made of a relatively rigid and / or more rigid polymer or plastic (polypropylene (PP) in this non-limiting example); however, this is not strictly required, and other materials such as polyoxymethylene (POM), acetal plastic, etc., can be used in other embodiments. The latter can also be used to improve robustness and provide a low-friction solution for its pivoting portion. In this non-limiting example, the dispensing cap 62 and handle 66 are also made of a relatively rigid and / or more rigid polymer or plastic. The fluid material dispensing mechanism 30 as described herein is configured to allow the use of stronger / harder plastics to enhance its robustness. The handle / lever ribs of the system from U.S. Patent No. 8,511,520 have been removed to enhance the cleanability of the dispensing mechanism 60.

[0056] As in Figure 2 As seen in the image, the dispensing mechanism 60 includes a first plate or upper plate 80. This plate may be referred to as a push plate, spring-biased plate, or spring plate, for example. In this example, plate 80 is planar and rectangular. In this non-limiting embodiment, the plate is made of metal (in this example, sintered metal). Plate 80 is configured to enhance the robustness and cleanability of the dispensing mechanism 60 and contrasts with the system disclosed in U.S. Patent No. 8,511,520, which may disclose a plastic push plate. In this non-limiting embodiment, the plate is made of stainless steel. In this non-limiting embodiment, plate 80 extends along a longitudinal axis 82, which is generally or substantially perpendicular to the longitudinal axis 46 of the bottle 44. Figure 7As seen in the image, the plate has a plate orifice 80A extending through it. In this non-limiting example, the plate orifice is off-center and coaxial with the longitudinal axis of the bottle. The plate 80 includes a first end or proximal end 80B and a second end or distal end 80C spaced apart from the proximal end. In this non-limiting example, the plate orifice 80A is closer to the proximal end of the plate than the distal end. In this non-limiting embodiment, the proximal end 80B of the plate 80 abuts against and / or is adjacent to the fulcrum 68G. The plate is selectively tiltable, wherein its distal end 80C is tiltable when the lever 68 is in the idle position. Figure 9 The first or upper position seen in the image is the same as when the joystick is in the actuated position. Figure 10 It moves between the second position or the lower position seen in the image. The proximal end 80B of the plate 80 has a function that allows it to move between the second and lower positions when the joystick is in the idle position. Figure 9 The first or lower position seen in the image, and the position where the joystick is in the actuated position. Figure 10 The second position or upper position seen in the image. Therefore, it can be said that the plate can move between the upper position and the lower position. In this example, the plate 80 is biased towards a non-angular position.

[0057] The plate is attached to the dispensing cap 62 and is axially spring-biased relative to the dispensing cap in a manner that facilitates its cleaning. The following are non-limiting embodiments of achieving this function. For example, in Figure 8 As seen herein, plate 80 is coupled to dispensing cap 62 in a manner that facilitates fluid communication between the plate and the interior 62E of dispensing cap 62. The plate is configured to be coupled to the dispensing cap in such a manner that the plate is fully and / or substantially exposed to the open bottom 62F of the dispensing cap to aid in its cleanability. Therefore, for cleanability, dispensing mechanism 60 may be said to include an open bottom or its underside portion. Thus, compared to the system shown in U.S. Patent No. 8,511,520, access to plate 80 may be said to be enhanced / open, and this may result in reduced material / plastic costs and enhanced cleanability. Dispensing mechanism 60 as described herein may be said to include a more open geometry and / or be configured to facilitate an open geometry to enhance / promote its cleanability.

[0058] The dispensing mechanism 60 includes a mounting member 84 via which the plate 80 is coupled to the dispensing cap 62. For example, the mounting member may be referred to as a plate holder or a spring plate holder. In this non-limiting embodiment, the mounting member 84 includes a planar member or a lower plate 84A. In this example, the lower plate of the mounting member is planar and generally rectangular in shape. The lower plate 84A of the mounting member 84 is axially spaced from the upper plate 80. In this non-limiting embodiment, the lower plate of the mounting member extends along a longitudinal axis 86, which is angled and / or generally or substantially perpendicular to the longitudinal axis 82 of the upper plate. In this non-limiting embodiment, the lower plate 84A of the mounting member 84 is angled to axis 46 and, in this example, generally or substantially perpendicular to the axis. The lower plate of the mounting member is coupled to and positioned within the interior 62E of the dispensing cap 62. The lower plate 84A of the mounting member 84 has an aperture 84A' extending therethrough, which in this example is coaxial with axis 46 and aperture 80A of the upper plate 80. In this non-limiting example, the lower plate of the mounting member is connected to the top portion 62B of the distribution cap 62 via a pair of spaced-apart fasteners 84B and 84C. These fasteners are configured to require only a screwdriver to thread the lower plate of the mounting member to the distribution cap: in this non-limiting embodiment, these fasteners have square heads to achieve this function. A handle 66 is thus operatively connected to the upper plate 80 and the lower plate 84A. In this example, fasteners 84B and 84C are enclosed by sleeves 84D and 84E. Each sleeve is in fluid communication with the interior 62E of the distribution cap 62. In this example, plate 80 is positioned between fasteners 84B and 84C and sleeves 84D and 84E. It can be said that the mounting member 84 comprises fasteners and sleeves.

[0059] The dispensing mechanism 60 includes a resilient member, in this example a spring 88. (As in...) Figure 9 As seen in the image, the spring is configured to be positioned in place via a spring boss 88A connected to the lower plate 84A of the mounting member 84. The spring 88 is positioned between the upper plate 80 and the lower plate 84A of the mounting member. The upper plate is connected to the mounting member 84 and is spring-biased axially upwards via the spring. The spring 88 is configured to bias the plate 80 toward a non-angular position and... Figure 9 and Figure 10 The joystick maintains contact with joystick 68 during its movement, as seen in the image. (Return to reference) Figure 8 The spring 88 is in fluid communication with the interior 62E of the dispensing cap 62 to aid in its cleaning. The spring 88 is fully exposed to the open bottom 62F of the dispensing cap to aid in its cleaning.

[0060] refer to Figure 9The dispensing cap 62, handle 66, lever 68, plate 80, mounting bracket 84, and spring 88 are thus operatively connected together to form a single unit. The dispensing cap, handle, lever, plate, mounting bracket, and spring, as described herein, are connected in a manner that facilitates cleaning without requiring disassembly of any of their components. The fluid material dispensing system 30, as described herein, may include a dispensing system that can dispense an effective number of parts from four or five (see U.S. Patent No. 8,511,520). Figure 2 A to Figure 2 The number of parts described in C is reduced to a single, effective piece / part. In this non-limiting example, the fluid material dispensing system 30 is further configured to reduce the volume of the material or plastic used by at least approximately 10%. The handle 66 and lever 68 may be referred to as the handle assembly, wherein the dispensing mechanism 60, as described herein, is configured to enable cleaning of the entire handle assembly as a single unit. Thus, the dispensing mechanism as described herein can be used to facilitate cleaning on the one hand, and on the other hand, its cleaning method promotes efficiency / time savings.

[0061] The dispensing mechanism 60 includes an elongated member, in this example, a rod 90. In this non-limiting embodiment, the rod is substantially cylindrical in shape and has a rounded or circular lateral cross-section. The rod 90 has a first end or upper end 90A and a second end or lower end 90B spaced apart from its upper end. In this non-limiting example, each end of the rod is configured for engagement with the rod and in this case includes a spherical end; however, this is not strictly required. The rod 90 extends along the axis 46 of the bottle 44 between its two ends. In this non-limiting example, the dispensing mechanism 60 includes a gripping member, cap, or knob 92 engaged with the upper end 90A of the rod; however, this is not strictly required. The rod 90 extends through an orifice 63 formed in the dispensing cap 62. The rod extends through an orifice, gap, or passage 69 formed within the lever 68, near or adjacent to the bottom 68B of the lever. In this non-limiting embodiment, the passage may be located in... Figure 6 The manual actuation portion 68H of the joystick, as seen in the image, is between the joystick's plate contact portion 68I. (Return to reference) Figure 9 The plate contact portion of the lever 68 and the split stop 76A can be located on the same side of the passage; however, this is not strictly required. Furthermore, the lever 90 is shaped to pass through plate orifices 80A and 84A'. The lower plate 84A is configured to facilitate and / or aid in the alignment of the lever relative to the plunger 56. In this non-limiting example, the lower plate is elongated and generally or substantially spans the lateral extent of the sleeve portion 62A of the dispensing cap 62, which can be used to further facilitate lever alignment.

[0062] As in Figure 10As seen in the image, rod 90 extends along / parallel to the first direction 58. In this non-limiting embodiment, the lower end 90B of the rod is configured to extend along the first direction (i.e., from...). Figure 10 From the perspective of [the device], when the rod is lowered, it engages with the plunger 56. The rod 90 is thus operatively connected to the plunger. In this non-limiting example, the plunger 56 includes a socket and / or resilient clip 56C configured to engage with the lower end 90B of the rod in response to an engagement force applied to the rod in the first direction 58. Thus, in this non-limiting example, it can be said that the rod 90 is connected to the plunger via a ball-and-socket joint. The engagement force is insufficient to overcome the frictional engagement between the plunger and the inner wall 44C of the bottle 44, thereby allowing engagement of the rod 90 with the plunger 56 without causing undesirable travel of the plunger and without corresponding dispensing of the fluid material 48.

[0063] Mounting element 84 and / or plate 84A can be configured to suppress linear movement of lever 90 (e.g., due to partial frictional interference, etc.) until the lever 68 moves from... Figure 9 The idle position seen in the middle pivots to Figure 10 The engagement position seen in the image. This causes the upper plate 80 to tilt (from its upper position at its distal end 80C to its lower position) and engage and / or join / connect with the rod 90 and along... Figure 10 The first direction 58, as seen in the image, moves. The upper plate and lever thus cause the plunger 56 to travel in the first direction. The control lever 68 moves from... Figure 10 The joint position seen in the middle Figure 9 The pivoting return motion of its idle position, as seen in the image, causes plate 80 to be at least partially released from the rod under the bias of spring 88 and move back toward the non-tilted position (where its distal end 80C moves from its lower position to its upper position).

[0064] Figures 11 to 17 A fluid material dispensing system 30.1 and its dispensing mechanism 60.1 according to another aspect are shown. Similar components have... Figures 1 to 10 The fluid material distribution system 30 and its distribution mechanism 60 shown have similar numbers and functions, except that a decimal suffix ".1" is added. The fluid material distribution system 30.1 and the distribution mechanism 60.1 are similar to... Figures 1 to 10 The fluid material distribution system 30 and the distribution mechanism 60 shown are essentially the same, but with at least the following exceptions.

[0065] As in Figure 14 As seen in the image, the lateral section of the elongated member 90.1 is polygonal, and in this non-limiting example, its shape is rectangular. Therefore, the external shape of the elongated member is a rectangular prism.

[0066] refer to Figure 17In this non-limiting embodiment, the lever 68.1 includes a support or rib 94; however, this is not strictly required, and such a rib may be absent in other embodiments. The rib is positioned between the top 68A.1 and the bottom 68B.1 of the lever. The rib 94 is configured to enhance the rigidity of the lever 68.1. In this non-limiting embodiment, the handle 66.1 includes an elongated member support or rib 96; however, this is not strictly required, and such a rib may be absent in other embodiments. The rib is positioned between the top 66A.1 and the bottom 66B.1 of the handle. The rib 96 is configured to enhance the rigidity of the handle 66.1. The rib is configured to help maintain the orientation of the elongated member 90.1 parallel to the first direction 58.1. The rib 96 may include, but does not necessarily include, an orifice or recess shaped to receive the elongated member through it. The rib is aligned with an orifice 63.1 formed in the dispensing cap 62. In this non-limiting example, rib 96 extends substantially perpendicular to axis 46.1 of bottle 44.1.

[0067] The dispensing mechanism 76.1 is configured to further minimize or suppress the forces applied to the components of the fluid material dispensing system 30.1. The following are non-limiting embodiments for achieving this function.

[0068] The tooth 72.1 is coupled to the top 68A.1 of the lever 68.1 and extends outward and / or upward from or adjacent to that top; however, this is not strictly required, and in other embodiments, the tooth may be positioned at other locations on the lever. In this example, the tooth includes a tapered end portion 98. The lateral cross-section of the tapered end portion is rectangular, wedge-shaped, or V-shaped. The lateral cross-section of the tooth 72.1 is generally L-shaped; however, this is not strictly required. According to a non-limiting embodiment, the tooth is coupled to the lever 68.1 and can be selectively removed therefrom. According to another non-limiting example, the tooth 72.1 is integrally connected to the lever to form a single unit.

[0069] In this non-limiting embodiment, the dividing mechanism 76.1 is located on or adjacent to the handle 66.1. In this example, the dividing mechanism is positioned adjacent to the top 66A.1 of the handle. The tooth 72.1 includes a first or lower portion 99A coupled to the lever, and a second or upper portion 99B coupled to its lower portion and angled outward relative to its lower portion at an angle Ω. In this example, angle Ω is an obtuse angle. In this non-limiting example, each of the portions 99A and 99B of the tooth 72.1 is generally rectangular prism in shape. Figure 14 As seen in the image, the lower portion of the tooth is shaped to fit within the inside 68E.1 of the lever 68.1, in this non-limiting example, tightly fitting therein and between, thereby spanning the two sides 68C.1 and 68D.1 of the lever.

[0070] The dividing mechanism 76.1 includes one or more dividing stops 76A.1, the shape of which is determined to abut against teeth 72.1 when the lever 68.1 is actuated. The dividing mechanism (and / or its dividing stops) is configured to transfer load from the lever 68.1 to the first plate or upper plate 80.1' such that the elongated member 90.1 can translate when the lever is actuated. The following are non-limiting embodiments of achieving this function.

[0071] As in Figure 16 As seen in this non-limiting embodiment, the segment stop 76.1 is enlarged, wherein the length LS.1 in this example is at least equal to and greater than the length LT.1 of the tooth. In this non-limiting embodiment, the length of the segment stop 76A.1 is greater than that in... Figure 11 The distance between the two sides 67A.1 and 67B.1 of the handle 66.1 seen in the image; however, this is not strictly required. (Return to reference) Figure 16 In this non-limiting example, the length LS.1 of the dividing stop 76A.1 generally or substantially corresponds to the length of the flange 66C.1. The dividing mechanism includes a clip 100 operatively connected to a handle 66.1. The clip is coupled to the handle 66.1 and / or can be considered part of the handle. The clip 100 is shaped to extend around one end 80B.1' of the plate 80.1' to facilitate angled engagement of the plate with the elongated member 90.1 when the lever 68.1 is actuated. The orifice 80A.1' of the plate is polygonal in shape, and in this non-limiting example, is rectangular or square. Reference Figure 17 In this example, tooth 72.1 is configured via its tapered end portion 98 to selectively abut or operatively contact handle 66.1, which inhibits further rotation of lever 68.1. Plate 80.1' is spring-biased and / or spring-loaded to engage the elongated member and inhibit movement of the elongated member opposite to the first direction 58.1.

[0072] As in Figure 14 As seen in the diagram, the dispensing mechanism 60.1 includes a spring-loaded second, bottom, or lower plate 80.1 axially spaced from the upper plate 80.1'. An elongated member 90.1 is configured to extend through plate openings 80A.1' and 80A.1 of the upper plate 80.1' and the lower plate 80.1. The lower plate is related in terms of components to... Figures 1 to 10 The plate 80 described in the distribution mechanism 60 shown is substantially similar and serves as that plate. The lower plate 80.1 is spring-biased and / or spring-loaded to facilitate the movement of the elongated member 90.1 until the lever 68.1 is moved to the actuated position, at which point the lever engages the lower plate with the elongated member.

[0073] refer to Figure 17 In this non-limiting example, the elongated member 90.1 of the fluid material distribution system 30.1 is movable relative to the plunger 56.1. A plate 80.1' may be referred to as and / or used as a spring-loaded locking plate to prevent or inhibit undesirable translation of the elongated member 90.1. Actuation, tilting, and / or depressurization of the spring-loaded locking plates 80.1 and / or 80.1' allows the elongated member 90.1 to selectively retract and / or move downward.

Figures 11 to 17 The fluid material distribution system 30.1 and its distribution mechanism 60.1 shown have the same numbers and functions, except that the decimal suffix ".2" replaces the decimal suffix ".1". The fluid material distribution system 30.2 and the distribution mechanism 60.2 are the same as... Figures 11 to 17 The fluid material distribution system 30.1 and the distribution mechanism 60.1 shown are substantially the same, but with at least the following exceptions.

[0075] The joystick 68.2 includes at least one portioning stop having a defined shape, wherein the distance traveled by the joystick is limited by direct contact between the portioning stop and a portion of the handle located within the travel path of the joystick. This thereby limits the distance traveled by the plunger to restrict the discharge of fluid material to a corresponding defined share. The following are non-limiting embodiments for achieving this function.

[0076] In this non-limiting embodiment, the joystick 68.2 includes elongated and / or enlarged side and / or rear portions and / or at least one rib, and / or one of a convex or concave portion (in this non-limiting example, a pair of concave portions or receptions or channels 102A and 102B extending along the left side 68C.2 and right side 68D.2 of the joystick). The channels are said to be coupled to and extend along the respective sides of the joystick. Channels 102A and 102B extend along the peripheral portions of the respective sides of the joystick. In this non-limiting embodiment, the lateral cross-section of the channels is U-shaped. The shapes of channels 102A and 102B are determined to receive one or more portions, for example, in a non-limiting example, receiving in… Figure 5 The distal peripheral portions of the two sides 67A and 67B of the handle 66, as seen in the image, limit the distance the joystick travels. The channel is configured to engage and align parallel to the peripheral portions of the two sides of the handle when the joystick 68.2 is in its fully actuated / engaged position.
