Beverage dispensing apparatus

Abstract

A beverage dispensing apparatus and associated method, the beverage dispensing apparatus comprising a frame (11) for removably positioning and holding a sealed beverage unit package (C) in a vertical orientation. A first piercing element (14) perforates a vent opening into the headspace of the beverage package (C) and subsequently, as the first piercing element is driven downward, a second piercing element (15) perforates an outlet opening into the beverage package, enabling the beverage to flow under gravity through a nozzle (17). An ultrasonic transducer (16) against the nozzle (17) can provide excitation energy that causes gas to disassociate from the solution, causing a creamy head to form on the beverage in a delivery vessel below the frame. A control vent valve (13) enables the flow through the nozzle (17) to be slowed or stopped, enabling a settling time and "two-part" pour.

Description

Technical Field

[0001] This invention relates to an apparatus for beverage dispensing. The apparatus and its corresponding method repeat beverage dispensing in a compact device, and in one form, enable the formation of a head on the beverage during / after the dispensing process. Beverages of the type associated with this invention will include gases in solution, such as carbon dioxide, nitrogen, combinations thereof, or any other inert gas suitable for this purpose. The beverage may be alcoholic or non-alcoholic, but this invention is particularly suitable for use with beverages such as cider, cocktails, beer, stout, ale, and strong stout, where the presence of a head on the beverage when presented to the consumer in a drinking vessel is conventional and desirable. Background Technology

[0002] The most common method of delivering beer to consumers is by dispensing drinks from kegs (i.e., large-volume / bulk containers with multiple servings) or single-serving containers (such as aluminum cans and glass bottles). Dispensing facilities are typically only available in public / restaurant settings due to their high cost and maintenance requirements. However, bars or similar establishments are not always able to store beverages in bulk containers (such as kegs) due to space and cost constraints. Storing kegs requires significant space, and the associated dispensing and cooling facilities also involve substantial costs for the operator, which may be impractical for relatively low sales volumes. Therefore, many establishments sell beverages stored in bottles or cans, typically kept in illustrated refrigerators at the back of the bar. Single-serving containers are also generally available for home use.

[0003] Beverage dispensers rely on pressurized gas to deliver beverages from a small container to drinking vessels (such as pint glasses). Gas pressure can be further utilized to force the beverage through a porous "cream plate," which promotes the expulsion of dissolved gas from the solution and, especially in the case of nitrogen-containing beers, results in a creamy head in the serving glass. A creamy head is undesirable in the context of lagers or other purely carbonated beverages because it causes excessive foaming and an overly large head, hindering comfortable consumption.

[0004] The use of conventional single-piece packaging cannot reproduce the head of a beverage dispensing system unless an alternative device / feature is used to simulate the effect. A common device used to simulate a beverage pouring head is the so-called "widget," which takes the form of a hollow plastic device inserted into a can or bottle during filling to float on the surface of the beverage in the sealed container. The internal volume of this widget is pressurized during the filling process, and when the beverage package is opened, the pressure difference causes a jet of gas / beverage to be released into the main volume of the beverage, thereby triggering the nucleation of dissolved gas to bulge out of the solution.

[0005] Small accessories are widely available and accepted in the market, but because they remain in used beverage containers, they increase the cost and time of the manufacturing process and generate plastic waste / impact on recyclability.

[0006] Alternative methods for producing single-serving heads are known. For example, ultrasonic excitation in a platform on which a beverage-filled container (e.g., a glass) can be placed will generate or increase the head on the beverage. WO2004011362 describes such an apparatus. Ultrasonic excitation causes cavitation in the liquid, which causes gas in the liquid to escape from the solution and thus form tiny bubbles that migrate to the surface of the liquid, thereby forming a foam head on the surface. The required facilities (e.g., a conductive platform in contact with a sensor) are relatively simple and do not require a large amount of space; therefore, they are suitable for use in homes or places of the aforementioned type (which only store bottled or canned beverages and may have space constraints). However, ultrasonic platforms are not suitable for achieving “two-part” pouring and inconsistencies can occur due to the thickness of the glass, etc.

[0007] Other ultrasonic devices are known to aid in foaming in beverage products. For example, a "foamer" device has been proposed that is attached to the open end of an aluminum can packaging. A beverage (e.g., carbonated lager) is poured through this foamer device, where it is subjected to ultrasonic waves, thereby enhancing foam formation as the beverage is conveyed to the glass. This pouring can empty the packaging in one go, and ultrasonic waves / foam can be applied as needed or in multiple pours by pressing a button, as long as carbon dioxide remains dissolved in the liquid.

[0008] Typically, available ultrasonic methods for producing wave foam require users to learn new delivery procedures, moving away from traditional tap-pouring systems where the glass is positioned and filled from below the dispensing nozzle. Summary of the Invention

[0009] This invention seeks to provide an alternative device, method, and system for dispensing beverages in single-serving volumes to consumers. A single serving refers to a canned or bottled product, distinct from a keg of beverages. This invention presents a useful alternative that at least replicates the appearance of beverage dispensing in affordable, compact devices for home or small-capacity bar use.

[0010] It is conceivable that the present invention will provide an improved apparatus and accompanying method for forming a desired head on a beverage and / or, in effect, a novel dispensing system for repeating beverage dispensing in a compact device, which need not be limited to beverages requiring head formation. In a preferred form, the apparatus should be simple to use and require minimal user intervention or at least minimal maintenance. Therefore, the user may be relatively inexperienced, and the process can be easily repeated to ensure consistent service quality.

[0011] The invention can take the form of a beverage dispensing device including receiving features or devices (e.g., brackets / holders / supports / frames / clamps) for positioning and supporting opposite ends of a beverage package (e.g., in an inverted configuration). In one form, the receiving structure is configured to position the beverage package above a delivery vessel (e.g., a pint glass) such that gravity assists in dispensing it into the vessel.

[0012] This invention can be represented as a beverage dispensing device comprising: a receiving structure for removably positioning and holding a beverage package sealed, for example, on a conveyor; a dispensing nozzle for dispensing beverage through the nozzle; a first piercing element configured to perforate a vent opening into the top space of the beverage package; and a second piercing element configured to perforate an outlet opening into the beverage package below the horizontal plane of the beverage contained within the package, the outlet opening being aligned with the dispensing end of the dispensing nozzle to achieve a direct flow path for the beverage to minimize turbulence toward the conveyor through the outlet opening. The device can be configured to pierce the vent opening before the outlet opening. In one form, the first piercing element is a cannula associated with a shut-off valve actuated via a biasing element having a spring force greater than that required to pierce both the vent opening and the outlet opening. In other words, the biasing element can be a spring that only allows the valve to engage to close the cannula once sufficient force has opened both the vent and the outlet.

[0013] The corresponding method includes the following steps: positioning and holding a sealed beverage package in a receiving device close to the dispensing nozzle; perforating a vent into the top space of the beverage package; and perforating an outlet into the beverage package below the horizontal plane of the beverage contained within the package, the outlet being aligned with the dispensing end of the dispensing nozzle, so that the beverage can be poured through the dispensing nozzle in a direct flow path under gravity to minimize turbulence and enter the drinking vessel.

[0014] In one embodiment, the invention can be implemented by a beverage dispensing device comprising: a receiving structure for removably positioning and retaining a sealed beverage package; a first piercing element configured to perforate a vent opening into a top space of the beverage package; a second piercing element configured to perforate an outlet opening into the beverage package below a horizontal plane of the beverage contained within the package; a dispensing nozzle for communication with the outlet opening; and an ultrasonic generating element for transmitting ultrasonic waves to the beverage. The device can be configured to perforate the vent opening prior to the outlet opening.

[0015] For convenience and hygiene reasons, the beverage package may be a single-serving volume; however, it is possible, depending on its internal volume, to dispense a limited number of multiple servings from the package, or multiple single-serving packages may be arranged in series for dispensing. In one form, the receiving device may be (e.g., by means of a telescoping feature) expandable to accommodate the volumes of multiple packages (as indicated by their length).

[0016] Once the package is in place, a perforating device associated with an actuator, piston, or similar engagement mechanism is pushed against the end of the beverage package and driven through the wall of the beverage package (the upward-facing end wall); thereby exposing the package to the atmosphere.

[0017] In a subsequent step, a piercing device engages at the dispensing end of the package to open communication with the dispensing nozzle and the downstream receiving container (e.g., a glass). Optionally, a transducer communicating with the wall of the nozzle applies ultrasonic waves to the beverage flowing through the nozzle, thereby promoting bubble nucleation. The ultrasonic signal can be pulsating or continuous during pouring. The desired operating frequency is 30-50 kHz, more preferably 35-45 kHz, and most preferably 40 kHz. Alternative ultrasonic delivery devices can be used, such as probes that enter the liquid associated with the piercing element in the headspace.

[0018] In one exemplary form, the piercing device acts coaxially (i.e., along the longitudinal axis of the beverage package) on the beverage package. One or both of the piercing devices may be movable toward the package. The corresponding piercing device may be a solid piercing / needle structure and / or a hollow cannula. However, the piercing element in the top space does not need to be coaxial with the outlet piercing element. Minimizing distribution turbulence is typically achieved by allowing direct flow through the nozzle from the pierced outlet without sudden twists / turns in the flow path.

[0019] In one form, the beverage package support structure includes a tiltable bracket for mounting a receiving vessel, such as a glass. The bracket can be biased to a tilted position and tensioned such that when the beverage is filled under gravity, the glass overcomes a spring bias and returns to an upright position. The spring bias can be suppressed during return to the tilted configuration, which is prepared for mounting the next glass. In this way, the suppressed return movement prevents the bracket from suddenly and violently moving to the tilted position when the glass is removed for serving.

[0020] This invention seeks to optimize the dispensing of single-serving containers of beverages ready for sale by using a simple, vertically configured top-bar dispensing device (e.g.), which utilizes ultrasound to promote head formation while minimizing turbulence in the dispensed liquid that can lead to the formation of large and undesirable bubbles. In this context, "ready for sale" means in a state where it is drinkable and has not been mixed with another liquid prior to dispensing / selling. In a particular example, the beverage package may contain a strong beer with gas in the solution, requiring a further foam-forming step to make the beverage best suited for sale.

[0021] The package needs to communicate with a dispensing end or outlet to allow beverage to flow out. The dispensing outlet may be attached to (or removed from) a housing or frame, which is associated with receiving features. The dispensing outlet includes a nozzle and a device for perforating the dispensing end of the beverage package, for example, to open a dispensing channel.

[0022] According to the invention, there are two perforation operations relative to the beverage container: a first perforation step to vent the encapsulation to the atmosphere and a second perforation step to open the dispensing mechanism. In one form, the dispensing speed and pause can be controlled by the venting operation. If the vent is closed or narrowed, the dispensing from the outlet will stop or slow down, respectively. This control aspect will enable the implementation of popular methods for serving strong beers (such as Guinness). ® The device is a two-part pouring mechanism. Ventilation can be controlled by a valve associated with the perforation device (in the case of a hollow cannula), and / or the perforation device can be controlled to advance into and exit through the perforated hole to adjust the size of the open vent. Surface features such as notches or channels and / or the bevel of the perforation device can be used to determine the effective area of ​​the vent and thus enable flow control.

[0023] In a broad aspect, the invention requires that the beverage package be held between its two ends. Each end engages with a joint having a perforated element and is timed such that the uppermost end is perforated first, thereby perforating the lowermost end to allow the package to be vented before being conveyed to a vessel by gravity.

[0024] In one configuration, the first perforation point is substantially away from the second perforation point, for example, at opposite ends of a beverage container. "Away from" should at least be interpreted as the outlet not being at the same end as the vent, where leakage could otherwise occur.

[0025] In one form, the outlet perforation device is a hollow element associated with a nozzle through which, during dispensing, the ultrasonically treated, ready-to-sell beverage flows toward a drinking vessel positioned adjacent to the nozzle. In examples where it is not necessary to promote head formation on the poured beverage, the ultrasonic device can be omitted from the dispensing outlet.

[0026] The receiving structure, feature, or device, or the overall housing of the apparatus, includes a means of clamping / holding the package in place such that opposite ends can be perforated. This clamp may be in the form of a support sized to receive an inverted beverage package (e.g., the end of a roll-formed aluminum can). In use, the receiving structure suspends the beverage package above a vessel to be filled (e.g., a glass), allowing the beverage to flow smoothly in a generally vertical direction with the aid of gravity. However, it is possible that the dispensing nozzle may be oriented at an angle (from vertical) to guide the beverage linearly from the perforated outlet to the waiting container, offset from the beverage package. In any case, the dispensing nozzle should be internally designed / sized to minimize pouring turbulence through it.

[0027] In one aspect, the device is expandable / retractable, for example, for storage and / or for adapting to different sizes / volumes of beverage containers. Specifically, a beverage dispensing device is provided, comprising: a receiving structure for removably positioning and holding a sealed beverage container; a first piercing element configured to perforate a vent opening into the top space of the beverage container; and a second piercing element configured to perforate an outlet opening into the beverage container below the horizontal plane of the beverage contained therein; wherein the device (e.g., the receiving structure) is configured to expand and retract along a longitudinal axis to accommodate sealed beverage containers of different sizes. This expansion and retraction (generally foldable) feature is adapted to reduce the overall height of the device for storage purposes and / or to adjust the device to accommodate beverage containers of different heights. The device may include a single support bracket or multiple support brackets / legs (e.g., each telescopic) to provide height adjustment.

[0028] As mentioned, the beverage package is preferably a single-serving / single-piece package, which is conventionally upside down (i.e., inverted) for mounting into the device. The external printing on the package can be correspondingly "upside down," such that the end / dispensing end is the "base" of the package. However, in further embodiments, inversion is not necessary, as the opening can be driven through the wall of the package regardless of orientation. In some forms, it may be desirable to form an opening through the sidewall or shoulder of the package rather than the end.

[0029] The device may be mechanically actuated and / or include timing electronics that control / automate the perforation sequence of the package once the beverage package is secured in place. Actuation may also achieve fine control of the vent, for example, by using a first perforation device as a plug. Examples of mechanical actuation may feature resilient bushings (e.g., compressible material and / or springs) that are positioned against opposing end surfaces of the package, which (in use) may provide, for example, a sequencing function, to ensure that the vent to the top space is formed through the wall of the package before the outlet opening is introduced at the other end. For example, axially advancing cylinders / bushings arranged coaxially along the longitudinal axis of the package may have different deformation characteristics. Examples of electronic engagement may include a motorized actuator at one end or each end, for example, where the vent end perforation device is driven by a motor, followed by perforation at the outlet. The outlet perforation may be driven or fixed by another motor. Equivalent variations will be apparent to those skilled in the art.

[0030] Compared to manual levers, electronic control via a motor is expected to provide the most consistent delivery options, where different users of the device will have different levels of force and capacity.

[0031] The method for dispensing beverage from a beverage package according to the present invention includes the following steps: positioning and holding a sealed beverage package in a receiving device; opening a vent at a first position of the beverage package; opening an outlet at a second position of the beverage package away from the first position; and dispensing the beverage from the beverage package into a vessel through the opened dispensing end. In one form, dispensing is performed while subjecting the flowing beverage to ultrasonic waves.

[0032] The dispensing speed can be controlled at the end of the vent. In practice, dispensing can be stopped / paused to allow settling time for the beverage before restarting dispensing and delivering the final volume. The cross-section of the vent can be adjusted / closed to control the volumetric flow rate of the dispensing. Attached Figure Description

[0042] The following description presents exemplary embodiments and is consistent with the appendix. Figure 1 This document serves to explain the principles of the invention. However, the scope of the invention is not intended to be limited to the precise details of these embodiments, as variations will be apparent to those skilled in the art and are also considered to be covered by the specification. The terminology used for components herein should be given a broad interpretation, including equivalent functions and features. In some cases, several alternative terms (synonyms) have been provided for structural features, but such terminology is not intended to be exhaustive.

[0043] Descriptive terms should also be given the broadest possible interpretation: for example, the term "comprising" as used in this specification means "consisting of at least part of," such that for each statement interpreting the term "comprising" in this specification, there may also be features other than or preceding that term. Related terms, such as "comprise" and "comprises," will be interpreted in the same manner. Directional terms such as "vertical," "horizontal," "upward," "downward," "upper," and "lower" are generally used for ease of illustration and are not intended to ultimately limit whether equivalent functionality can be achieved with alternative dimensions and / or orientations.

[0044] The description herein relates to embodiments with specific combinations of features; however, it is envisioned that further combinations and cross-combinations of compatible features between embodiments will be possible. In fact, isolated features may function as part of the invention independently of other features and are not necessarily required as part of a complete combination.

[0045] Figure 1 A first embodiment of the dispensing device 10 according to the invention is illustrated in a broad sense. Functional elements are visible, namely: a support structure / housing 11 including a main support / leg, an actuation mechanism 12, an air valve 13, an upper movable tube and sealing assembly 14, a lower fixed tube and sealing assembly 15, an ultrasonic transducer 16, a nozzle 17, and a bracket 18. Not explicitly visible in the figure are the electronic circuitry for controlling the power to the transducer, motor, and air valve. A beverage container C is shown positioned between tubes 14 / 15, held above a glass G, in which the beverage is ultimately intended for sale.

[0046] Figure 2 The exemplary use of the device is illustrated in the first series of steps (i) to (iii). Specifically, between steps (i) and (ii), an actuation mechanism 12, triggered by the control circuit, causes the top cannula 14 to move toward the end of the container C. At step (ii), this action pierces the top of the container C, thereby releasing pressure by venting the liquid in the container to the atmosphere.

[0047] The top tube, surrounded by the deformable bushing 19, continues to move downward, pushing the container C against the second deformable bushing 20 and finally against the upright tube 15 at the dispensing end of the device. Continued downward movement causes the bottom end of the container to be pierced by the tube 15, resulting in liquid flow at atmospheric pressure. Notably, due to the open vent into the top space, the liquid flow is essentially laminar (rather than turbulent), allowing air to enter freely without disturbing the liquid. Avoiding turbulence is crucial for producing strong beers (such as Guinness). ® High-quality, consistent dumping is a key consideration.

[0048] At step (iii), the liquid has begun to fall / pour through nozzle 17 into glass G. As the liquid enters glass G, it flows past ultrasonic transducer 16, which is positioned against nozzle 17. The high-frequency vibration of transducer 16 causes nitrogen to escape from the solution in a controlled and efficient manner, thereby creating a "turbulence" in the glass so that a desired head can be formed after settling.

[0049] Figure 3The illustration shows steps (iv) through (vi) of the second series. Specifically, between steps (iii) and (iv), as the glass G is filled, the spring-loaded mechanism associated with the holder 18 slowly pivots from an initial position of approximately 45 degrees to an upright position at the end of the first pour. This holder movement automatically provides an ideal dynamic angle of incidence throughout the pouring process to avoid liquid turbulence that would diminish the quality of the pour. In the illustrated form, the holder 18 is biased to the tilted position, and tension in the bias is calculated to support the glass G in the tilted position. This bias is overcome when additional weight is added to the glass G via the liquid beverage, allowing a smooth transition to the upright position. Furthermore, in a preferred form, the natural return bias to the tilted position is suppressed when the glass is removed from the holder 18 to slow the return movement.

[0050] At the end of the first pour, in step (iv), valve 13 is closed, thereby creating back pressure in the headspace, which slows the flow of liquid through nozzle 17. This allows the liquid poured into glass G to settle and form a head in the usual manner. In an alternative form where the perforated device 14 has a solid core, the size of the vent (between zero section and upper dimension) can be controlled by its movement relative to the hole formed in the encapsulation. The perforated device can have multiple surface features, such as notches or channels. In one form, the device can have resilient sidewall portions to provide a sealing function against the edge of the vent.

[0051] At step (v), after the liquid has settled, the air vent 13 and / or the perforated hole can be reopened to allow the remaining liquid in container C to flow, thereby refilling the glass and reproducing the classic two-part beverage pouring.

[0052] When glass G is removed from holder 18 (holder 18 returns to the tilted position), the system resets before the next dispensing cycle.

[0053] Step (vi) indicates that the height of structure 11 can be telescopically adjusted to accommodate various beverage container serving sizes. When not in use, the structure can also be fully retracted to create a more compact form for storage, thus providing a particular space-saving advantage for home consumers.

[0054] The illustrated form of the invention shows a single bracket or leg 11 including a telescopic shaft. Alternative forms may feature additional support brackets / legs, such as a dual-bracket configuration, where the legs are arranged on opposite sides of the package for improved stability. Alternative structures may provide similar telescopic configurations, such as scissor mechanisms, reciprocating pictographs, threaded shafts, or bellows. The height can be secured in place by pins or other braking devices. The height can be adjusted by a threaded shaft arrangement that engages or disengages with the telescopic legs.

[0055] The beverage container C can be of any volume, such as the common 440 or 568 mL aluminum cans manufactured by many suppliers, but preferably has a “blank” can end suitable for being punctured for dispensing, i.e., without a pull tab. It is worth noting that the orientation of the beverage container (shown as “inverted”) is arbitrary, as suitable joining features can be incorporated into new packaging designs or modified into more conventional container shapes.

[0056] The compression and engagement features of the device can be automated by using at least one actuator, which is preferably controlled by a processor / electronic device housed within or separate from the main housing. Nozzle 17 can be supplied as a removable device along with the main unit for cleaning.

[0057] As will be clear from the operational method of the exemplary embodiments, a timing sequence of steps is required for most efficient use. The timing of piercing the can for dispensing and introducing atmosphere can be mechanically achieved by a resilient bushing 19 (or an equivalent deformable structure, such as a spring-biased telescopic bushing having a sealing surface in contact with the can end) positioned near the upper end to create a liquid / airtight seal against the container C around the piercing element 14 as downward pressure begins.

[0058] A second resilient bushing 20, or a spring-loaded bushing 20, is positioned close to the dispensing cannula 15 to create an airtight seal against the container C at the bottom end of the device. The deformable bushings 19, 20 may have different elastic properties, such that the venting cannula engages first to form a vent before the dispensing cannula 15. In other words, the weaker bushing 19 may yield first under compressive force to engage the piercing element 14 downward into the top portion of the container C, while simultaneously forming a seal above the opening driven through that end. Topspace pressure is released via a closable valve 13.

[0059] The cannula 15 (in the fixed position) then punctures the base / bottom of the container C on the cannula 15, while the bushing 20 creates a seal above the formed dispensing opening to prevent leakage.

[0060] Linear actuation of each needle / cannulas 14 / 15 can be automated by electronics with separate actuator devices, or as a single actuator that moves the first cannulas against a fixed second cannulas. In principle, this movement / actuation can originate from the lower portion of the device, i.e., where a rigid bushing 20 surrounding the cannulas 15 presses the container C against a soft bushing 19, which deforms and allows puncture by the cannulas 14 before a sustained force engages the cannulas 15 to open the dispensing end.

[0061] An exemplary embodiment produces a filling auxiliary container (glass G) in which a creamy head is formed due to gravity flow through an ultrasonically enhanced nozzle 18. It is known in the art that the head formation can be improved by a two-step dispensing procedure that can be repeated by temporarily shutting off the flow through the nozzle 18 via a valve 13 and allowing the poured liquid to settle if desired.

[0062] Figure 4 An alternative form of the invention is illustrated, in which the piercing / pouring sequence is manually actuated by the handle 21. In this form, motorization is not required, but the same general steps for dispensing are followed. For example, the handle 21 applies force leveraging to the piercing / sealing assembly 14, which contacts the upper end of the beverage container (not shown). The space at the top of the container is vented before engagement and perforation through the dispensing end piercing / sealing assembly 15, which occurs naturally by further force applied from the lever 21.

[0063] The flow begins to pass through nozzle 17 and fill glass G. The bracket 18 supporting glass G is biased toward an inclined position, where the added weight in the filling glass overcomes the bias and begins to move the glass upright.

[0064] Valve 13, communicating with the top space of the container, can close the vent and temporarily stop dispensing to allow settling and head formation. Alternatively or additionally, as previously mentioned, venting and flow rate can be controlled by advancing and withdrawing the first perforation device to serve as a partial or complete plug above the vent.

[0065] In an additional form, the display may provide visual indicators and / or step-by-step guidance to the user operating the device. This guidance may include prompts for inserting or removing containers, as well as time information, pouring characteristics, and temperature.

[0066] It is worth noting that the specific steps / sequences / valve operations (including operating range, etc.) executed by the firmware are a useful aspect of this invention. Therefore, the algorithms for these steps and the associated controls can form the basis of an independent invention.

[0067] Figures 5 to 9 The illustration shows a second motorized embodiment of the invention, namely a motorized valve system capable of piercing both ends of the can while simultaneously opening and closing the top valve using a vertical movement. Laminar flow of the liquid can be achieved. As in the previous embodiment, closing the top valve prevents liquid flow, while opening the top valve to varying degrees provides precise flow control.

[0068] Figure 5 The diagram shows Figure 1The most familiar components in the first embodiment include, for example, the actuation mechanism 12, the air valve 13, the upper movable cannula and sealing assembly 14, the lower fixed cannula and sealing assembly 15, the ultrasonic transducer 16, and the nozzle 17. Figure 5 The embodiment is characterized by two retractable legs on either side of the dispensing mechanism. As in Figure 1 In this system, the dispenser can expand and contract to fit the size of the beverage package being loaded (e.g., an aluminum can). Figure 6 and Figure 7 Further details regarding the arrangement of seals and valves are provided.

[0069] pass Figure 8 and Figure 9 Steps (i) to (vii) outline the operational sequence of the second embodiment. Specifically:

[0070] (i) Display the starting position.

[0071] (ii) The motor pushes the plunger assembly downward, which in turn drives the top cannula 14 downward via spring 22. The motor continues to push until the top cannula pierces the top of the can, thereby releasing pressure and venting the liquid in the can to the atmosphere. The spring bias 22 resists compression as the cannula 14 is driven into the can C.

[0072] (iii) The motor advances until the top cannula assembly 14 touches the bottom, thereby sealing the top cannula to the can via the annular flange / skirt 23. As the motor continues to advance, it pushes the can C downwards until the bottom cannula 15 pierces the bottom of the can. At this point, the bottom seal 20 also seals to the can. As the motor continues to advance, the spring 22 is compressed, and the plunger assembly is driven downwards until the top valve 13 (typically biased towards the open position of the pancake-shaped diaphragm) moves to abut against the upper passage of the cannula 14 and closes. This shuts off the airflow to the top space and creates a vacuum within the can, thereby preventing liquid from flowing through the nozzle 17.

[0073] (iv) The motor retracts to pull the plunger upward, thereby opening the top valve 13. This disengages valve 13 from the upper passage of cannula 14 and allows air (see...). Figure 6The airflow, denoted as A, passes through the opening around the cannula and then re-enters the can through the cannula, allowing the liquid to flow through the nozzle 17 at atmospheric pressure. It is noteworthy that the liquid flow is laminar (not turbulent) because the cannula is vented at the top, allowing air to enter freely without disturbing the liquid. The liquid flows through the ultrasonic transducer in the nozzle and into the glass. Avoiding turbulence is a key part of using ultrasound to produce high-quality, consistent pouring for nitrogenous beverages. The high-frequency vibrations of the transducer cause nitrogen to escape from the solution in a controlled and efficient manner, creating the desired “tumble” in the glass—that is, promoting small bubbles while minimizing turbulence that could hinder the formation of large bubbles that would otherwise collapse more quickly. As the glass fills, the spring-loaded mechanical support 18 slowly pivots from the 45-degree starting position to the vertical position at the end of the first pour (in... Figure 2 and Figure 3 (More visible in the middle). This bracket movement provides an ideal dynamic angle of incidence throughout the pouring process to avoid liquid turbulence that would diminish the quality of the pour.

[0074] (v) At the end of the first pour, the motor advances and the top seal 13 closes (no airflow A), which significantly slows the liquid flow. This allows the liquid to settle in the glass and form a head.

[0075] (vi) After the liquid settles, the motor retracts and reopens the top seal, allowing the remaining liquid to flow and refill the top of the glass. This "two-part" pouring is desirable for regenerating some nitrogenous beverage products (such as Guinness). ® The allocation of ).

[0076] (vii) Once the glass is removed from the holder, the can can be popped out. This causes the top assembly to retract completely, allowing any remaining liquid to drain and the can to be removed.

[0077] It will be apparent that features from the embodiments described herein may be interchangeable or replaced by equivalent features without departing from the scope of the invention.

[0078] The method and apparatus according to the invention, as described above, are advantageous because they are simple to use and can be manufactured in a variety of ways using available materials. Ideally, the unit would be compact and comfortably adapted to a commercial bar-type environment. It not only provides the practical benefits of enhanced beer appearance and taste but also offers uniqueness through a process that is likely to attract consumer attention. The form of the invention can be specifically developed for home use.

[0079] For example, the present invention can be summarized as an apparatus, system, and method for dispensing beverages from a single-serving beverage package (e.g., an aluminum can C) (specifically for the purpose of forming a head on the beverage poured from said package, although the key objective is to repeat the dispensing in a compact device), thereby minimizing cost and quality issues for ease of deployment. In operation, the sealed package C is positioned and held in a receiving housing 11, in which, firstly, the top space end of the package is vented through a piercing element 14, and secondly, the dispensing end is opened for gravity dispensing into a drinking vessel G. An ultrasonic device acts on the liquid flowing at the dispensing end.

[0080] The use of valves or closing devices (e.g., at the venting end of the headspace, but alternatively or additionally at the dispensing end) can advantageously improve the control of beverage delivery to implement pauses to allow settling time.

[0081] One aspect of the invention can also be broadly described as a beverage dispensing device and associated method, comprising a frame for removably positioning and maintaining a sealed beverage unit package. A first piercing element perforates a vent opening into the top space of the beverage package, and subsequently, a second piercing element perforates an outlet opening into the beverage package, allowing the beverage to flow under gravity through a nozzle (in communication with the opening). An ultrasonic transducer against the nozzle provides excitation energy to degas the solution. Thus, a creamy head is formed on the beverage in a delivery dish below the frame. A valve or other form of control over the vent opening can slow or stop the flow, thereby enabling settling time and a “two-part” pouring.
