Abstract
Description
[0001] A beverage package containment and pouring device
[0002] Technical field
[0003] The present invention relates to a handheld package containment and pouring device for a beverage, especially for pouring from a single serve package supplied in a sealed form, where the beverage is infused with a gas that is to be encouraged out of solution for forming a creamy head thereon.
[0004] Background to the invention
[0005] A gas infused beverage, such as stout beer (e.g. Guinness®), requires agitation at the time of dispense to form a desirable, creamy head. In a bar environment, beverage is delivered under pressure to a glass from a storage vessel with a multi-serve volume, such as a keg. The delivery line passes through a "creamer plate", i.e. a plurality of restricted apertures, where gas (for example, nitrogen) breaks out of solution and encourages further nucleation to form tiny bubbles. In the glass, after pouring, these bubbles rise to the surface and result in a desirable and characteristic creamy head.
[0006] A known alternative foaming method, as may be incorporated into a device for home use, involves use of an ultrasonic transducer. In such a system the beverage is exposed to ultrasonic waves that cause agitation and, hence, formation of foam. W02022180050 describes use of an ultrasonic transducer built into a pouring attachment device for a beverage container, e.g. an aluminium cannister (can). The transducer, being located against a flow path of the beverage, causes agitation in the nitrogenated beverage such that when it reaches a glass, the poured beverage eventually settles and forms a desirable head. The attachment is designed to cover the beverage container at an already open outlet end, leaving the rest of the container / package exposed.
[0007] Further "bubbler" type devices, such as JP2018122892, are known for coupling to the opening end of an aluminium can package. A beverage, e.g. carbonated lager, is poured through the bubbler device where it is subjected to ultrasound, enhancing froth formation as it is delivered to a glass. The pour can drain the pack all at once, with ultrasound / foam applied by the press of a button when needed, or in multiple pours so long as carbon dioxide remains dissolved in the liquid.
[0008] It is noteworthy that a "nitrogenated" or other gas-infused beverage as discussed herein often includes a mix of gases in solution, such as a mix of nitrogen and carbon dioxide. However, small bubbles and a creamy head are characteristic of the presence of particular gases (e.g. nitrogen) in an effective concentration.
[0009] In recent times, a creamy head has become desirable in connection with other beverage types, such as cocktails. Therefore, a need has been identified for a pouring device that is suited to use with such beverages.
[0010] Summary of the invention
[0011] The present invention seeks to provide a pouring device that, in one form, is an evolution over known "bubbler" devices, suitable for re-use with a single unit pack of beverage, particularly a gas infused beverage. At least the invention will provide the public with an alternative delivery means for a beverage.
[0012] In a broad aspect of the invention, a pouring device for a disposable or unit container / package of beverage is provided according to claim 1. A corresponding method is outlined by claim 21. Further features are described by the dependent claims. The embodiments disclosed herein are unified by a common inventive concept, namely provision of an outer housing for receiving therein a packaging unit, with further provision of package puncturing means that facilitates pouring through a flow channel that may be configured for applying agitation / nucleation (e.g. by mechanical stirring and / or sonication). The device is particularly suited for delivering gas-infused beverages. The selection of beverage type is up to a user, but may at least include beer, cider or a ready to drink ("RTD") cocktail. The pouring device may consist of a sealed electronic assembly within the housing configured to securely enclose a beverage pack. During use / pouring, the pack may be sealed in communication with the flow channel to avoid unintended leakage outside of the housing.
[0013] The pouring device incorporates a structure to pierce the package (e.g. a blank can end) and open communication with a flow channel for pouring. In one form, the piercing structure may be manually activated, e.g. by rotational / turning movement of an externally accessible annular wall portion, e.g. a collar or indeed an upper or lower part of the housing itself. Rotational movement may be translated (e.g by a helical guide surface) into linear motion of a cannula or other sharp, needle-like, element which subsequently forms an opening in the package (e.g. through a blank can end). In the present context "linear motion" and similar means in a direction generally coincident with or parallel to a central longitudinal axis of the device and / or package.
[0014] Other forms of gaining mechanical advantage for piercing, other than rotation, may be contemplated, such as over-centre-levers, etc. Indeed, piercing may be activated by direct manual force applied by the user, via a push button or palm operated arrangement directly acting to press down on a sharp piercing means, Accordingly, the present invention may not be limited to precise details of the mechanism to activate piercing.
[0015] However, in an embodiment of particular interest, puncturing is achieved by engaging an upper part of the housing onto a lower part, e.g. by a threaded connection and using a translated linear motion from the threaded connection to cause penetration of a piercing device (e.g. a cannula offset from a longitudinal axis) into a beverage package. Upon engagement / penetration into the package, the piercing device (being fixed inside the upper part of the housing) is rotating with the upper part and could otherwise stall further movement if it encounters a rotationally fixed beverage package. Therefore, a means to allow the package to rotate (or in effect to be rotationally fixed) with the upper housing as it moves toward the lower housing on a helical thread will prevent stalling of the rotating operation or gouging a larger opening. A rotating platform located internally at the base (lower part) of the housing can enable such package rotation during assembly of the housing.
[0016] The diameter of the opening formed by piercing should be such as to achieve a desirable flow velocity. A suitable diameter of opening formed into the package may be 8 to 18 mm, e.g. 12 mm, but could be larger. The cannula may be retracted via a resilient member, e.g. a torsion spring tightened by rotation of an activation control (annular portion, collar or the like) in an activation direction when puncturing the package. The activation direction could be clockwise or anti clockwise.
[0017] In embodiments, the activation control is configured to return to a starting point when release by a user; i.e. it is the action of the user releasing the activation control (and the activation control then returning to its original position - as a result of the torsion spring) that causes the piercing element to retract. In other words, rotation of the activation control in one direction causes extension / lowering of the cannula (to engage with the can end for piercing), while rotation (either automatic via a spring or manually) of the activation control in the opposite direction causes retraction / raising of the piercing element.
[0018] In forms where the piercing element is fixed to extend from an engagement / underneath surface of an upper part of the housing, withdrawal of the piercing element occurs during removal of the upper part from the lower part of the housing, via a screw thread or the like, at disassembly. When a package is contained within the closed housing, the piercing element will remain driven into the package.
[0019] In a particular form, the device housing is a closeable container, e.g. resembling a cocktail shaker or other handheld-type device. The sealed unit package of beverage may be inserted / loaded into a first body part of the housing (e.g. the lower part referred to above) to enclose a first / lower portion thereof, while a second body part of the housing (e.g. the upper part referred to above) encloses a second / upper portion of the package. The container parts may be fitted together with mating threaded surfaces. The action of closing the container preferably couples, via a seal, the sealed beverage package with the pouring channel of the device at the upper part of the closeable container. The device housing may take various forms, such as an elongate sleeve that substantially encloses the side walls of a disposable beverage package inserted from one end of the housing. In this way, the single use beverage package (such as an aluminium can) may not be fully enclosed on all sides. Indeed a window / opening may be provided in a side of the dispenser housing so that the package is at least partially visible. However, it is generally envisaged that a base of the package should be secured relative to an outlet end so that driving a puncturing element into the package is controllable.
[0020] The device described herein encloses a pierced open end of the can / package and facilitates a flow path toward an outlet of the device. As mentioned, the device may seal to the can end, e.g. by virtue of an annular or o-ring seal or the like, such that tilting the device (and package fixed therewithin) allows the liquid to be poured into a glass in a familiar manual / handheld operation via the flow path / outlet without leakage in any other direction.
[0021] In one form a vent to atmosphere is provided, e.g. distant to the outlet / nozzle, for venting the container volume to atmosphere.
[0022] In one form, at least part of the device assembly (e.g. an upper part of a two-part housing construction) is fully sealed against moisture ingress and houses an electronic circuit. The electronics may be associated with an agitation means, e.g. an ultrasonic transducer / actuator or motorised propeller / impeller / stirrer able to cause agitation of beverage flowing into / through the pouring channel. Electronic switches / controls may be implemented for other improvements such as haptic feedback that assist with operation of the device.
[0023] In the case of an ultrasonic means of nucleation, a surface thereof preferably contacts (e.g. by an adhesive) the wall of a resonance chamber / flow path such that, while pouring, ultrasonic waves are transmitted through the wall of the chamber to the beverage flowing inside. This has the effect of breaking the dissolved gas out of solution simultaneously with pouring of the beverage into a vessel. Subsequent flow through the flow path toward an outlet, downstream of agitation, is relatively smooth to mitigate large bubble formation. Ultrasonic transmittance may be direct to the flow path / beverage or indirect via an intermediate structure.
[0024] In the case of a motorised agitation means, such a motorised agitation device may be located at an inlet end to the flow path, proximate the pierced / formed opening of the beverage package / unit. In this way, beverage passing into the flow path is agitated, encouraging gas out of solution and the formation of fine bubbles. However, as above, subsequent flow through the flow path toward an outlet, downstream of agitation, is relatively smooth to mitigate large bubble formation.
[0025] In embodiments, the inlet to the flow path may comprise or be through a perforated wall, i.e. a partition of many apertures. There may be a specific pattern of perforations for flow control. The motorised agitation means, e.g. impeller, may draw beverage through the perforation which controls agitation in a way that produces desirable head formation.
[0026] It is likely that the apertures may be specific to the shape and dimension of the propeller / impeller. As mentioned, a perforation pattern controls and regulates the liquid flow into the resonance chamber / flow path, and past the agitation device.
[0027] In preferred forms, the beverage path after agitation and onwards to the delivery vessel consists of a smooth walled conduit, although this may include abrupt bends.
[0028] In a particular embodiment, the beverage outlet, e.g. at the terminus of the flow path, includes a closure element. The closure may be a pop-up lid with a flow path facing engagement surface that moves toward and away from the outlet to perform a closing and opening operation respectively. Operation of the closure may be manual or as a step in an automated dispense procedure, i.e. the closure may open the outlet for beverage flow therefrom after a piercing element has formed an opening into the sealed package and / or has subsequently retracted. The closure may be spring-biased and activated by a rotating collar, e.g. by turning in the same direction, or alternatively an opposite direction, to the direction for coupling the upper housing to the lower housing. In one form, the flow path / channel downstream of an inlet formed by or proximate the piercing element has a relatively planar cross section, e.g. a letterbox or square cross section. The channel may smoothly transition to an outlet end whereupon, at a closure end, it may be directed in another direction, such as perpendicularly to the substantive flow path. A narrowed outlet, compared to upstream sections of the flow channel, slows flow to increase contact time between the beverage and the agitation means.
[0029] According to an expression of the invention, a pouring device for enclosing a disposable beverage package is provided. The device comprises: a housing for substantially enclosing at a dispense end and base end of the beverage package. A coupling feature can be provided for coupling to the dispense end of the package. A flow channel can be defined by an inlet, for location proximate to the dispense end of the package. An outlet can be provided, distal from the dispense end of the package. A piercing mechanism can be configured for activation when the disposable beverage package is enclosed in the housing or during the enclosing operation.
[0030] In this way, the disposable beverage package is first located into and / or surrounded by the housing, e.g. secured thereinto, before, simultaneously or during when a piercing mechanism is activated which forms an opening into the beverage package (which will be pressurised by dissolved gas). Once a puncturing operation is complete, beverage can then be poured by tilting the housing and enabling beverage to flow through the flow channel under gravity toward a vessel. In a particular form, beverage is subjected to agitation within or at the inlet to the flow channel, however, the piercing aspect can operate independently of agitation.
[0031] In a particular form, the piercing mechanism is activated through a mechanical advantage, i.e. where a user's manual input is amplified and / or translated to enable piercing of a sealed package wall. In one form, the user's input simultaneously activates any electronic features of the device.
[0032] In embodiments, the coupling feature comprises a sealing element for sealing an end of the beverage package into communication with the flow channel. Alternatively or in addition, a seal element may surround the piercing element such that it compresses and seals against an opening in the package formed by the piercing element. In this way, when the piercing element is a cannula, beverage is able to flow through the piercing element, but does not leak outwardly from the puncture formed opening. Embodiments may incorporate a vent to form a communication channel proximate a headspace of the package and atmosphere, thereby facilitating pouring from the punctured package.
[0033] As mentioned, the common inventive concept of the various embodiments described herein generally revolves around a pour facilitating device that serves as an enclosure for a disposable beverage package, and provides an internally operable means to form an opening through a wall (e.g. an end) of the package to deliver beverage therefrom through a flow path and into a drinking vessel.
[0034] Pouring steps may be indicated by a visual prompt. The visual prompt may comprise a lighting sequence or display. The visual display / prompt may additionally or alternatively be used to indicate charging status to a user (e.g., blinking green light may indicate recharging is in process; solid green light indicates recharging is complete; blinking red light indicates battery is low; and blinking orange light indicates error).
[0035] Such a visual display may function independently of the piercing mechanism of the invention. In other words, providing a visual display / prompt for a user in the context of a pouring device is an independent invention from the specific embodiments described herein, such as comprising a mechanism activated through mechanical advantage (e.g. rotatable collar or housing part) to activate / move / engage a cannula.
[0036] In various forms, actuation of the piercing mechanism may be achieved by motorised means or physical manipulation of the device. For example, an externally accessible annular member (e.g. activation control in the form of a collar or rotation of a substantive housing part itself) may be turned to engage the piercing element into the package. The piercing element may be withdrawn to open communication to the flow channel and / or include a hollow section to form part of the flow path. A coupling feature of the pouring device, e.g. that integrates a sleeve and / or seal for coupling with a beverage pack, may be a fixed size (e.g. diameter) or, in alternative forms, be configured to couple with a range of beverage pack sizes / diameters.
[0037] The pouring device disclosed herein enables a user to pour smaller volumes than the full volume of the package for consumption, such as a "half-pint" from a pint package (a "pint" being approximately 0.57 L in metric units). Smaller volumes are envisaged, such as 250mL suitable for a pre-mixed cocktail.
[0038] Any remaining beverage can be poured at a later time and still successfully foam, so long as gas remains in solution. The beverage may be a premix or component of a cocktail, beer, or other alcoholic and non-alcoholic beverage products / analogues. A sealing lid may facilitate successful pouring at a later time.
[0039] Pouring from a device according to the present disclosure is intuitive to use and easy to control, resulting in a high-quality dispense and, where agitation is applied, excellent head formation. These factors combine to create an improved experience for the consumer compared to other known approaches. Furthermore, the pouring device is especially suited to nitrogenated or other gas infused beverages.
[0040] After use, the used / empty package is easily removed from the device housing (e.g. by disassembling upper and lower housing parts) for loading with a next package or for cleaning of the device. The package, e.g. aluminium beverage can, being substantially one material and preferably not including a plastic insert (i.e. a "widget" provided for encouraging nucleation of gas bubbles for head formation), is easily recyclable. To aid cleaning of the device, some parts may be removeable from the assembly and cleaned. The remaining electronic assembly is preferably sealed to IP67 standards, and so can be easily cleaned under a running tap without risk of damage.
[0041] In forms of the device utilising motorisation and / or ultrasound, rechargeable (e.g. NiMh or Lithium-ion) cells may be installed that can be easily charged , e.g. via a common USB port. Such a port preferably has a waterproof rubber cover. By its nature the device is reusable and, with energy saving considerations, agitation may be activated to create a head on dozens of pours before recharge is needed. Energy can be conserved, for example, by using pulsed agitation spread over a period of time to create a consistent pour of liquid, or by programming agitation to occur only during a pour (e.g., only when the pouring device has been tilted at least 90 degrees from its central longitudinal axis). The degree at which the pouring device is tilted by a user may be determined using, for example, an accelerometer mounted on the pouring device's control electronics (e.g., a PCB). Other variants may allow for a manual switch to allow for different pouring effects, foam / head depths, and length. Compared to a mains-powered "surger" device where ultrasound must travel through several layers (e.g. a metal platform, pooled water, thick glass base, beverage), a pouring device according to the invention consumes a fraction of the energy.
[0042] The device described herein may be particularly adapted for encouraging a chain reaction of bubble nucleation in beverages infused with nitrogen or other gases for production of a smooth, creamy head. However, the apparatus can be employed as an alternative to known bubbler devices that foam carbonated beverages. Indeed, the package-enclosing housing with in-built piercing function is not limited to use with gas infused beverages requiring pouring of a creamy head.

[0051] Detailed description of the invention
[0052] The following description presents exemplary embodiments and, together with the drawings, serves to explain principles of the invention. However, the scope of the invention is not intended to be limited to the precise details of the embodiments or exact adherence with all components, since variations will be apparent to a skilled person and are deemed also to be covered by the description. Terms for components used herein should be given a broad interpretation that also encompasses equivalent functions and features. In some cases, several alternative terms (synonyms) for structural features have been provided but such terms are not intended to be exhaustive.
[0053] Descriptive terms should also be given the broadest possible interpretation; e.g. the term "comprising" as used in this specification means "consisting at least in part of" such that interpreting each statement in this specification that includes the term "comprising", features other than that or those prefaced by the term may also be present. Related terms such as "comprise" and "comprises" are to be interpreted in the same manner. Directional terms such as "vertical", "horizontal", "up", "down", "upper" and "lower" may be used for convenience of explanation, usually with reference to the illustrations, and are not intended to be ultimately limiting if an equivalent function can be achieved with an alternative dimension, orientation and / or direction.
[0054] The description herein refers to embodiments with particular combinations of features, however, it is envisaged that further combinations and cross-combinations of compatible features between embodiments will be possible. Indeed, isolated features may function independently as an invention from other features and not necessarily require implementation as a complete combination to have advantages over prior art.
[0055] Figures 1 to 4 show external views of a general embodiment of pouring device according to the present disclosure. Particularly, the device 10 may be embodied by a reusable housing configured for receiving a separate disposable beverage package to be accommodated therewithin (not visible). The general external appearance of the unit may be common to embodiments described herein, although can differ in cosmetic details and the placement of functional features.
[0056] The housing which embodies a beverage package containment and pouring device according to the invention may be comprised of two separable, upper 11 and lower 12, parts which couple together, e.g. by a screw thread, to enclose a beverage package, such as an aluminium cannister (can). The join between parts 11, 12 is designated 13. A closed base 14 may be flat for standing upright on a tabletop surface.
[0057] The lower part 12 may substantially accommodate the beverage package, while upper part 11 may house mechanisms and / or electronics for operating the pouring features described hereinafter. Certain components required for operation are externally visible such as a twistable activation switch control / ring / section 15 (which may comprise surface features to facilitate manual gripping thereof), a lid 16, an outlet closure 17, and charging port 18 (e.g. USB-C). Also visible is a thin strip 19 where a visual indicator such as LED lighting may be located. The strip 19 may be activated to provide visual prompts during operation.
[0058] Referring to Figures 5, internal detail of a first embodiment is visible. For example, the lower part 12 and base 14 of the housing may be coupled by a screw thread which is either permanently fixed or only decoupled for cleaning etc. In some forms, the threaded connection proximate the base 14 may be the primary access for a package C to be introduced and removed from the device. Lower part 12 and base 14 securely hold a sealed package (e.g. a 250mL slimline beverage can C) in place which includes a blank can end B. In alternate forms, can end B may be provided with a weakened wall portion or other features to facilitate piercing. Can end B may be a conventional pull tab where the piercing means is configured to puncture a blank part of the wall or form, by a blunt ram, an opening by utlising a pre-existing mouth shape scored into the end (e.g. without lifting the pull tab). In this way, the term "piercing means" may be analogous and interchangeable with a general "hole-forming means."
[0059] Upper housing 11 comprises / houses a mechanical piercing feature (e.g. cannula 20), a package seal 21 (e.g. an annular wipe seal), control electronics (e.g. PCB 22), transducer 23 (e.g. for encouraging nucleation of bubbles in a gas-infused beverage), liquid flow path 24 (e.g. for regulating / controlling flow during a pour), top cover / lid 16 (e.g. for enabling an open / pouring function), rotatable activation control 15 (e.g. for activating the cannula 20 and switching on electronically controlled aspects), illumination elements 19 (e.g. for providing user feedback and prompts), charging port 18 (e.g. a USB-C format or equivalent socket) and one or more air vents 25 (e.g. for pressure equalisation and controlling the speed of liquid flow).
[0060] Features and associated function of the device are best understood by reference to a method of its use. A suggested sequence of use for the first embodiment is outlined with reference to Figures 5 to 8 and the following steps:
[0061] Step 1.1 (Figure 5)
[0062] • Place a sealed beverage package C with a blank can end B into the lower part 12 and base housing 14;
[0063] • Secure the upper part 11 to the lower part 12 of the housing through the coupling of their respective screw threads to form a closed container. In this state, a beverage package C is securely housed within the device 10, which may have an external appearance analogous to a cocktail shaker.
[0064] Step 1.2 (Figure 6)
[0065] • Manually rotating the activation control 15, e.g. in a clockwise direction, may engage aspects of the control electronics, i.e. functions as a switch;
[0066] • Halo illumination 19 may be configured to flash intermittently indicating a "ready" state.
[0067] It is noteworthy that, in the first embodiment, activation control 15 may be in the form of an annular sleeve / moveable sidewall / collar of the device which rotates about a central longitudinal axis. While activation control 15 turns about an axis, other external wall parts of the device remain static, e.g. an uppermost portion 26.
[0068] Step 1.3 (Figure 7)
[0069] • Continued rotation (e.g. through 90 degrees) of the activation control 15 may mechanically engage the cannula 20 to pierce the blank can end B;
[0070] • Halo Illumination 19 may flash repeatedly to indicate an "in use" state.
[0071] Mechanical advantage enabling actuation of the cannula 20 may be achieved by engagement of an internal surface of activation control 15 with a helical surface feature (i.e. screw thread) associated with the cannula or its mounting structure. For example, rotational movement (that is otherwise spatially fixed along the longitudinal axis) of activation control 15 causes a translation to linear motion of the cannula 20 along the longitudinal axis and toward can end B.
[0072] Step 1.4 (Figure 8)
[0073] • Once the cannula 20 has pierced the blank can end B it may retract, e.g. release of the activation control 15 by the user allows the activation control to return to its original position, causing the cannula 20 to retract automatically such as via a torsion spring (not visible) that is tensioned during manual rotation of the control 15; • Lid 16 opens, moving away from uppermost portion 26, which correspondingly opens a liquid flow path to outlet 17 indicated by dotted directional arrows;
[0074] • Illumination 19 may be fully solid indicating the unit is ready to pour;
[0075] • Upon tilting the device with outlet 17 pointing toward a receiving vessel (e.g. glass), liquid is able to flow via the liquid flow path 24, past transducer 23 which has been energised according to the control electronics, optionally in response to the handheld tilting motion;
[0076] • It is noteworthy that vent 25 enables equalizing airflow into a volume above and within the package C and effectively controls the speed of the pour and / or mitigates any "glugging" which might affect smooth pouring and bubble formation.
[0077] Lid 16 may "pop-up" automatically under spring loading, e.g. when released at the end of the activating rotational movement of control 15.
[0078] In a case where the beverage is infused with a dissolved gas, transducer 23 excites the liquid in the flow path 24 and encourages nucleation / bubbles out of solution. Such nucleation is propagated during the pour and continues in the poured beverage. At least part of the flow path may be designated a resonance chamber and may be optimised for ultrasonic excitation. A feature that could be incorporated with all illustrated embodiments (e.g. as an alternative or enhancement) is inclusion of a functionally active surface within the flow channel 24. A means of encouraging bubble nucleation such as that described by WO2017 / 076829 may be implemented, i.e. a contact surface comprising nanostructures.
[0079] The user may finish pouring when the package is empty or at any desirable time. If empty, the illumination may indicate such a state, i.e. flash red for "empty" or the like. The device is returned to an upright position. A flow sensor in communication with path 24 may be configured to measure volumetric dispense and deactivate nucleation when substantive contents have been dispensed and the package is empty or at any specified volume of product. Lid 16 may be pressed back down manually and held with a latch or like element (not shown), loading a spring element for future use.
[0080] The container 10 may be twisted open, i.e. separating parts 11 and 12, to expose spent package C for substituting with a replacement sealed package or for cleaning of the device.
[0081] All electronics are reset for next use.
[0082] Figure 9 shows a perspective view of internal detail in accordance with the first embodiment, except that an alternative form of seal 21 is shown, specifically a compression seal that is sandwiched between a rim of the beverage package and an annular ledge of the device itself. Force applied during closing (e.g. via screw threaded mating parts) enables the housing to maintain a seal and prevents leakage into the lower portion 12 of the housing or out of the join 13 in the housing wall. This is a particular advantage of a housing formed by two parts that are joined by forces applied in opposing directions.
[0083] Figures 10 to 15 show a second embodiment / variation of pouring device 10 where the agitation method does not require a transducer 23. Instead, agitation is achieved by fluid movement through a perforated partition 30 at the inlet and / or mechanical agitation (such as through the action of a motorised propeller / impeller / stirrer 28).
[0084] Figures 10 and 11 respectively show an example of a rotatable agitator 28 and perforated wall 30 which may be fitted across an opening to the flow channel 24 shown in Figure 12. In this way, spinning of agitator 28 may draw beverage through the openings in wall 30 and encourage dissolved gas out of solution. Wall 30 may be a part that is removeable for cleaning or replacement.
[0085] As above, with reference to Figures 13 to 15, a suggested sequence / method of use best highlights functional aspects and features. Components in common with the first embodiment are labelled with the same reference numerals and steps 1 and 2 are analogous in both embodiments. The main difference is, instead of transducer 23, nucleation is encouraged by adoption of the propeller / impeller 28 driven by a motor 29 for affecting flow through the perforated wall 30. The propeller / impeller or agitator may have two functions: (i) to draw liquid through the perforated wall; and / or (ii) to agitate the liquid mechanically.
[0086] A suggested sequence of use for the second embodiment may be as follows:
[0087] Step 2.1
[0088] • Place a sealed beverage package C with a blank can end B into the base 14 and / or lower part 12;
[0089] • Secure the upper part 11 of the housing onto the lower part 12 through the coupling of their respective screw threads to form a closed container.
[0090] In this state, analogous to the first embodiment, a beverage package C is securely housed within the device 10, which may have the external appearance of a cocktail shaker.
[0091] Step 2.2 (Figure 13)
[0092] • Manually rotating the activation control 15, e.g. in a clockwise direction, may engage aspects of the control electronics, i.e. functions as a switch;
[0093] • Halo illumination 19 may be configured to flash intermittently indicating a "ready" state.
[0094] Step 2.3 (Figure 14)
[0095] • Continued rotation (e.g. through 90 degrees) of the activation control 15 may mechanically engage the cannula 20 to pierce the blank can end B;
[0096] • Halo illumination 19 may flash repeatedly to indicate an "in use" state.
[0097] Step 2.4 (Figure 15)
[0098] • Once the cannula 20 has pierced the blank can end B it may retract, e.g. release of the activation control 15 by the user allows the activation control to return to its original position, causing the cannula 20 to retract automatically by action of a torsion spring loaded with tension during manual turning of control 15; • Lid 16 opens, moving away from uppermost portion 26, which correspondingly opens a liquid flow path to outlet 17 indicated by dotted directional arrows. It is notable that the lid may automatically pop up when the cannula is fully extended, which lets a user know that the can has been pierced;
[0099] • Illumination 19 may be fully solid indicating the unit is ready to pour;
[0100] • Upon manually tilting the device with outlet 17 pointing toward a receiving vessel (e.g. glass), liquid is able to flow via the liquid flow path 24 toward a vessel (not visible);
[0101] • Propeller / impeller / stirrer 28 is activated according to the control electronics (optionally in response to tilting) and beverage passes (or is drawn) through the perforated wall 30 (defining a liquid chamber 31 above the package C) and the propeller / impeller / stirrer 28, thereby influencing liquid flow and bubble formation;
[0102] • Particularly, liquid is agitated before or as it passes through the liquid flow path 24 for subsequent dispense.
[0103] • It is noteworthy that vent 25 enables pressure equalizing airflow into the volume 31 above and within the package C and effectively controls the speed of the pour and / or mitigates any "glugging" which might affect smooth pouring and bubble formation.
[0104] A third embodiment is described according to Figures 16 to 19. This embodiment outlines an alternative piercing mechanism, although still activated by manually instigated rotational movement that translates into a linear motion along or parallel to a longitudinal axis for driving a hole forming element into a wall of a package. The third embodiment may borrow and implement other compatible features described above interchangeably, such as any method of nucleation (or none) for a beverage and various functions of electronic operation which may include visual and / or haptic / tactile feedback.
[0105] Figures 16 and 17 provide an overview of a complete assembly of a package containment and pouring apparatus 10, comprised of an upper housing part 11 and lower housing part 12 which couple via a threaded engagement, e.g. helical ridge 32 that is received by mating helical channel 33. This coupling arrangement of first and second housing parts is generally equivalent to the first and second embodiments, except that the manual operation of coupling parts 11 and 12, e.g. by holding upper part 11 static and engaging / turning lower part 12 via thread 32 / 33 to be pulled theretoward (or vice-versa), additionally drives a piercing element 34 into package C.
[0106] Since, as shown, piercing element 34 is preferably offset from a centreline / longitudinal axis of the device / package, it is preferable to enable package C to turn in time (i.e. be rotationally locked) with the coupling operation so that engagement toward a fully closed position is not stalled or impeded. In other words, lower housing part 12 is configured to allow package C to rotate independently thereof.
[0107] Rotation of package C within housing part 12 may be facilitated by a free-rotating platform 35 located internally at base 14. Such a "lazy Susan" device allows rotation (or indeed nonrotation if lower part 12 is being turned) of package C about its longitudinal axis in either clockwise or anticlockwise direction while housing part 12 is static or turns. In the illustrated form, platform 35 is comprised of a base rotationally fixed with the base of the outer housing part 12. A package engaging surface (in use, rotationally fixed with the package) of platform 35 is rotatable about a central axis and one or more bearings therebetween that facilitate smooth movement. Base 14 may comprise a rubber seal that covers any otherwise externally visible aspects of platform 35 (such as its axle / hub).
[0108] According to the foregoing features, it is possible to couple upper 11 and lower 12 parts by relative screwing rotation to form an enclosure about package C while simultaneously driving piercing element 34 linearly into an end thereof. Preferably, coupling is performed while in a vertical orientation and thread 32 has already entered track 33, to minimise leakage. In any event, an annular seal 36 located around piercing element 34 preferably engages the outlet end surface of package C before or simulateously with puncture, thereby containing any fluid expelled therefrom. Seal 36 is a flared bush shape that splays out as it is compressed, preventing beverage from escaping outside the flow channel 24 formed by walls of priecing element 34, e.g. in the form of a cannula. Notably, Figure 16 shows the housing 10 in a pre-assembled position, whereas Figure 17 shows the housing in a fully closed position where piercing element 34 has penetrated to its maximum depth into package C. It is notable that the seal 36 is shown in an engaged state, deformed into a flat / squashed shape against the package end.
[0109] Unlike the first and second illustrated examples, the hollow nature of the piercing element 34 forms a first inlet section of flow channel 24, configured for directing liquid flow past an agitation means 23 and toward an outlet 17.
[0110] As in earlier embodiments, an activation collar 15 or the like may mechanically and / or electronically activate a lid 16 and / or the agitation means 23. Haptic and / or visual features may be delivered through or adjacent collar 15. Indeed, the collar 15 could be configured to cause the rotational mechanical advantage to engage offset cannula 34 in a similar (e.g. linear) way to the first and second embodiments, which could also allow for retraction by reverse movement of the collar. Haptic features may be generated by a motor (not shown), and may be programmed to provide feedback at specific times during the pouring device's operation (e.g., when the agitation means 23 are active).
[0111] In the illustrated form according to the sequence of Figures 18 and 19, lid 16 is embodied as a pop-up lid that may be operated by a torsion spring 37 in a comparable way to that previously described. Lid 16 includes a flange 38 that overhangs and acts as a closure for outlet opening 17 when in the "closed" position of Figure 18; whereas Figure 19 shows an "open" position where flange 38 has moved to expose opening 17 and enable pouring of beverage therefrom through tilting, via channel 24.
[0112] The lid 16 can be returned to a down / closed position, including by being pushed down manually, in order to keep contents of the package fresh and / or during removal of package C for replacement. In some forms, lid 16 may be omitted entirely or take a different form such as a cap or plug.
[0113] The embodiment of Figures 16 to 19 may not require a vent as essential, i.e. there is not necessarily a vent to atmosphere for facilitated replacement of ambient gas in exchange for liquid volume lost from the package headspace. However, as shown in Figure 16, a vent 25 may be formed radially from the cannula opening 34 into a space in the housing about package C. A further vent (or channel in communication with vent 25) may be formed through a side wall of housing 11 to communicate with atmospheric pressure. This is especially useful if flow channel 24 is sealed by lid 16 at outlet 17.
[0114] It will be apparent from the foregoing that all embodiments are configured to obtain analogous results, i.e. provision of a sealed package-holding device that has a user-operable internal piercing mechanism for enabling a controlled pour from a handheld device. Optionally, the device may include an agitation means such as an ultrasonic transducer and / or mechanical device (e.g. propeller / pump and creamer plate type arrangement).
[0115] By way of summary, the embodiment(s) described herein outlines a containment and pouring device for a disposable package of beverage, e.g. an aluminium can. The device includes upper and lower housing parts for enclosing the beverage package which may, when coupled, have the appearance of a cocktail shaker. The upper part interfaces with the package proximate where it will be punctured and houses a flow channel and a piercing mechanism, e.g. a cannula, configured for piercing the package. Activation of the piercing function is via rotation of part of the housing, e.g. a collar or upper housing part as a whole relative to the lower part, and translation of that rotational motion into linear motion of the cannula relative to the package. In this way, principle features of the embodiments are provision of a handheld housing to enclose and isolate a package from surroundings, which is able to translate the mechanical advantage of a rotational / twisting movement of a part of the housing into linear movement of a piercing element that forms an outlet hole in the package. After piercing, the cannula may retract by action of a torsion spring primed by the activating turning motion, or stay in position and form an inlet for the beverage flow / pouring path. Furthermore, a lid may pop up to open the flow channel for pouring into a glass by tilting the device. Electronics within the device may control a visual or tactile indicator, e.g. a strip of LEDs and / or haptics, to provide user feedback and prompt steps of use. An agitation means may be provided, proximate the flow channel, for encouraging dissolved gas out of solution in the beverage to facilitate a desirable head on the poured beverage. It is notable that the mechanical agitation approach, i.e. motorised agitator and / or apertured plate, described herein may function independently as an invention from the first aspect where an internal piercing means is activated after a package is securely enclosed by a housing. As such, a pouring device may be provided which comprises: a device for attaching to a beverage package, e.g. to an end of a cannister, wherein the device provides a flow path between an inlet and an outlet; and a mechanical agitation means to cause localised agitation to beverage flowing through the flow channel and encourage dissolved gas out of solution. The agitation means may be located within or at an entrance to the flow path.
[0116] Variations of a pouring device include:
[0117] 1. Provision of a housing for receiving a disposable package of beverage, comprising a pouring channel to communicate with an open end of the package and visual indicator means (such as those described herein) which provide user prompts as to steps for pouring a beverage from the package.
[0118] 2. Provision of a housing in the form of a sleeve for receiving a disposable package of beverage, further comprising a piercing element that is engaged for forming an opening as a package is inserted in a longitudinal direction into the sleeve. The piercing element may be a cannula which provides entry to a flow channel toward a pouring outlet. In one form, the package may be positioned on a base part and forms a closure for the package within the housing during insertion and piercing. In this way the device is a bottom-loaded sleeve and force for the piercing operation is applied manually during the insertion process by firmly pressing from above while the package is secured against a surface.
