Abstract:
A receptacle for storing, pressurizing, and dispensing packaged beverages. The receptacle includes an airtight chamber with a removable lid, wherein the joint between the lid and the chamber is also airtight. A gas valve allows for the inflow and outflow of gas, and a tap port and tap stem allow the beverage to be dispensed without breaking the seal of the chamber. A pressure relief valve allows for more rapid depressurization. The chamber can be used at high and low pressures, such as a partial vacuum, to prevent oxidation of a number of open beverages, such as beers, wines, and sodas. A pressure gauge port coupled with an optional pressure gauge allows a user to verify the appropriate pressure for the type of beverage being preserved. The gas valve may be disposed on a base of the receptacle, as may the pressure relief and/or the pressure gauge port.

     FIELD OF THE INVENTION 
     This invention relates generally to receptacles, and, more specifically, to receptacles for storing and preserving packaged beverages. 
     BACKGROUND OF THE INVENTION 
     Opening a packaged beverage invariably leads to oxidation of the beverage. Additionally, beverages that are carbonated or otherwise gas-dispensed, such as with carbon dioxide or nitrogen, will begin to lose the gas once the pressure is released, causing the beverage to go flat. The present disclosure contains systems and methods for preservation of packaged beverages.

       FIG. 1  is an isometric view of the receptacle for storing and preserving beverages. The receptacle is comprised essentially of a vessel  100  and a lid  200 , and it is designed to receive beverage packages, such as beverage package  150 . 
     In some embodiments, vessel  100  may be further comprised of a chamber  110 . In some embodiments, chamber  110  may be tubular, having a volume formed by a circular perimeter. In other embodiments, chamber  110  may have a rectangular volume. In still other embodiments, chamber  110  may have a triangular volume. The volume formed by chamber  110  may be any number of shapes without altering the function of the device. In some embodiments, chamber  110  may be comprised of a thermoplastic resin material. Such material may include, but is not limited to, acrylic resin, acrylic plastic, or another acrylic formulation. In other embodiments, chamber  110  may be comprised of a metal. Further, chamber  110  may be comprised of any number of rigid or semi-rigid materials without altering its function. In some embodiments, chamber  110  may be comprised of a material with specific heat properties, such as being able to withstand very high or very low temperatures. In some embodiments, chamber  110  may be comprised of a material with specific strength properties, such as being able to withstand very high pressures exerted from within the chamber, being able to withstand very high external pressures, or being able to withstand a significant difference between the internal and external pressures on the chamber. 
     In some embodiments, vessel  100  may be further comprised of a base  120 . Base  120  will generally be coupled with chamber  110  in such a manner that the joint is airtight. For example, a channel  122  may be formed inside the top side of the base for receiving the chamber. The channel may be round and have substantially the same inner and outer diameters as the chamber  110  (“substantially the same” here meaning that the width of the channel defined as the distance between the inner and outer diameters may be slightly larger than the thickness of the chamber, e.g. 0.01″ larger, in order to snugly accommodate the chamber). The channel formed inside the top side of the base may be a square-cut channel and may receive the chamber  110  in a permanent, semi-permanent, or removable fashion. The channel may receive a gasket onto which the chamber is seated, the gasket having an appearance similar to that depicted in and discussed with respect to  FIGS. 6 a -6 c   . In embodiments where the channel of the base receives the chamber with a permanent joint, no gasket may be needed to maintain an airtight character of the vessel. 
     In some embodiments, base  120  will be approximately the same area as the perimeter formed by chamber  110 . In other embodiments, the area of base  120  will be larger than the perimeter formed by chamber  110 . Base  120  may be comprised of the same material as chamber  110 . In other embodiments, base  120  may be comprised of a different material than chamber  110 . In still other embodiments, base  120  and chamber  110  may be formed as a single unit, such that no seam exists between the two elements. 
     In some embodiments, vessel  100  may be further comprised of fastener  130 . In some embodiments, vessel  100  may have multiple fasteners  130 . In a non-limiting example,  FIG. 1  shows vessel  100  with three fasteners  130 , and a fourth is not shown as it is obscured by other elements. In another non-limiting example, if the perimeter formed by the chamber is triangular, vessel  100  may have only three fasteners  130 , such as one at each vertex. A primary function of fastener  130  is to couple lid  200  with the vessel  100 , and this function may be accomplished in a number of ways. Another primary function of the fastener is to create a removable airtight joint between vessel  100  and lid  200 , which can also be accomplished in many ways. In some embodiments, fastener  130  may be a pin, rod or a bolt. In the exemplary embodiment shown in  FIG. 1 , fastener  130 , which is a bolt, may be joined with base  120  and extend substantially parallel to the height of chamber  110 , wherein lid  200  is placed on chamber  110  and bolts and washers are used to tighten the lid onto the chamber. This embodiment is discussed in more detail in another section. In other embodiments, fastener  130  may be comprised of a ratchet strap system, wherein the airtight joint is created by disposing the strap around the vessel  100  and lid  200  and cranking the ratchet until the strap is taut. In other embodiments, fastener  130  may be a clamp fastener, wherein a first portion of the fastener is coupled with the external perimeter of chamber  110  and a second portion of the fastener is coupled with lid  200 , and the portions are coupled and tightened to form the airtight joint. In some embodiments, fastener  130  may be a system comprised of a clip and a toothed belt, wherein one of the clip or toothed belt is disposed on the external perimeter of the chamber  110  and the other of the clip or toothed belt is disposed on lid  200 , then the portions are coupled and tightened to form the airtight joint. A number of methods could be used without altering the primary functions of fastener  130 . 
       FIG. 1  further depicts details of lid  200 . In some embodiments, lid  200  will be approximately the same area as the perimeter formed by chamber  110 . In other embodiments, the area of lid  200  may be larger than the perimeter formed by chamber  110 . Lid  200  may be comprised of the same material as chamber  110 . In other embodiments, lid  200  may be comprised of a different material than chamber  110 . In some embodiments, lid  200  is further comprised of a gas valve  210 . Gas valve  210  is a port for gas, allowing a user to fill chamber  110  with a gas of the user&#39;s choice using a tank type of the user&#39;s choice. The valve may be a Schrader or Presta type valve. Such a valve would facilitate use of an inflator for bicycle tires as the tank type of choice. Other tank types of choice could include a paintball CO2 tank, a CO2 welding cylinder, or any other supply of CO2. The valve could also be a hose barb for receiving tubing leading to the tank type of choice. In a different embodiment, the valve may include a threaded fitting for receiving threadably-coupleable gas line tubing. Other gases may be introduced into the chamber, such as nitrogen, using an appropriate tank such as a nitrogen cylinder or a nitrogen bicycle inflator 
     In some embodiments, a regulator may be disposed in the gas line, between the receptacle and gas tank of choice. The regulator facilitates a constant pressure within the receptacle. When beverage content is dispensed the regulator would provide more gas to the chamber up to the desired pressure set by the user. 
     In some embodiments, gas valve  210  may be a one-way valve, allowing a user to only add gas to chamber  110 . In other embodiments, gas valve  210  may be a two-way valve, through which gas may be added or removed from the chamber. In some embodiments, lid  200  may be further comprised of a pressure relief valve  220 . Pressure relief valve  220  allows a user to release a controlled or semi-controlled amount of gas to reduce the internal pressure of chamber  110 . In different embodiments, the gas valve and pressure relief valve may be the same valve. Lid  200  may be further comprised of a pressure gauge port  230 . Vessel  100  is designed to withstand a wide range of pressures, and a pressure gauge port gives users the option of attaching a pressure gauge  231  to monitor and help control the pressure in chamber  110 . 
     A gasket  240  disposed in a channel on the bottom surface of lid  200  may, in some embodiments, be included to facilitate the airtight seal between vessel  100  and lid  200 . In some embodiments, gasket  240  may be substantially the same shape and perimeter as chamber  110 . In some embodiments, gasket  240  may be slightly larger or slightly smaller than the perimeter formed by chamber  110 , in order to facilitate the proper joint between vessel  100  and lid  200 . More details about gasket  240  are included further herein. 
     Lid  200  may be coupled with vessel  100  through fasteners  130 . In the embodiment depicted in  FIG. 1 , fasteners  130  are bolts. When lid  200  is placed on top of vessel  100 , fasteners  130  are passed through holes  250  (depicted in  FIG. 2 ), and the joint is completed when washers  260  and nuts  270  are tightened onto the bolts. This is one exemplary embodiment of a coupling arrangement, and should not be construed as limiting the disclosure in any way. 
     The receptacle for storing and preserving beverages may include a means by which the beverage or other content can be dispensed without removing the package entirely. In  FIG. 1 , this is depicted by tap  280 . Tap  280  allows a tap system  300  to be coupled with lid  200 . Lid  200  may, in some embodiments, include a tap stem  290 . In some embodiments, tap stem  290  is disposed through tap  280  and into the beverage package, allowing a user to draw the beverage into the stem and then dispense through tap system  300 . In some embodiments, tap  280  may be a screw valve. In different embodiments, tap  280  may be a hose barb. In some embodiments, tap  280  may be a ball lock valve (depicted in  FIG. 10 ). In other embodiments, tap  280  may be a Sankey valve. In still other embodiments, tap  280  may be coupleable with any commercial tap system, as depicted in  FIG. 9 . Tap system  300  may be as simple as a hose  310  with a tap spout  320  at the end (a “picnic tap”). In other embodiments, tap system  300  may be a ball lock system, a Sankey system, an American tap system, or any other commercial tap system. In a preferred embodiment, tap  280  can be coupled with any existing tap system the user may own. For example, a beer faucet may be coupled to the tap  280  rather than the picnic tap (hose and spout) arrangement. 
       FIG. 2  depicts how the lid and vessel of  FIG. 1  when fasteners  130  are bolts. Fasteners  130  are disposed through holes  250 , which aids the proper alignment between the perimeter of chamber  110  and gasket  240 . Tap stem  290  descends into beverage package  150 , allowing a user to dispense the beverage even when lid  200  is properly sealed onto vessel  100 , isolating a beverage package inside the receptacle. 
     The method of use of the embodiment in  FIGS. 1 and 2  may be comprised of removing lid  200  from vessel  100 , then placing beverage package  150 , in this example a beer growler, into chamber  110 . Once beverage package  150  is in place, lid  200  is placed onto vessel  100 , with the gasket disposed within a channel on the bottom surface of lid  200 , the channel matching the perimeter formed by the rim of chamber  110 . Fasteners  130  are disposed through holes  250  (shown in  FIG. 2 ), and washers  260  are placed onto the fasteners. Bolts  270  are hand-tightened on fasteners  130  to form an airtight seal aided by compression of the gasket which is pressed into the channel on the bottom surface of the lid by the rim of the chamber during tightening of the bolts and fasteners. A gas tank of, for example, carbon dioxide is coupled with gas valve  210  and gas is pumped into chamber  110 . The user may choose to open pressure relief valve  220  a few times to release any remaining oxygen from chamber  110 . The user may choose to watch pressure gauge  231 , which is coupled with lid  200  through port  230 . When the gas has created the appropriate pressure for the particular beverage, the user will stop the flow of gas into chamber  110 . When the user dispenses the beverage through tap system  300 , the pressure gauge will fall, alerting the user that more gas should be pumped into the chamber. Alternatively, use of the receptacle with a CO2 tank and regulator will ensure that gas enters the chamber to supplement pressure lost by dispensing the beverage. When the user wishes to remove the growler from the chamber, the user simply interrupts the supply of gas and releases some of the pressure through pressure relief valve  220 , then unscrews nuts  270 , removes washers  260 , and pulls the growler from the chamber. 
     The present invention allows a user to make custom gas and pressure settings. This is critical because different packaged beverages require different gas environments and pressures to maintain freshness, effervescence, and/or entrained gas content.  FIG. 3  depicts the invention as it might be used with a wine bottle as beverage package  150 . Wine requires different gas and pressure settings than beer. For instance, a user may choose not to fill chamber  110  with gas, and may simply choose to substantially remove the ambient air from the chamber, creating a vacuum or near vacuum. In another example, a user may choose to replace the ambient air with nitrogen, which prevents the oxidation of the wine. Tap system  300  can still be used in this configuration, allowing a user to keep the wine free from exposure to oxygen, which substantially improves the life of the bottle. 
       FIG. 4  depicts the invention as used with a two-liter bottled beverage as the beverage package  150 . The present invention is versatile enough that nearly any prepackaged beverage could be stored in it for preservation. In the embodiment depicted in  FIG. 4 , chamber  110  may be slightly longer than it would be for other uses, but, because tap stem  290  descends into the bottle, differing lengths are not necessarily required.  FIG. 5 b    shows tap stem  290  in more detail. In a preferred embodiment, tap stem  290  is comprised of three parts: first segment  291  is rigid, second segment  292  is flexible, and third segment  293  is rigid. In this embodiment, stem  290  can reach the sides and corners of beverage packages, and can be used with packages of different sizes and heights, such as a growler or a two-liter bottle of soda. 
       FIG. 5 a    shows an exemplary embodiment of tap system  300 , wherein the system is comprised of a nut  330 , which couples with tap port  280 , a hose  310 , and a spout  320 . This is merely one example of tap system  300 , and, as discussed earlier herein, any number of tap systems can be coupled with lid  200 . 
       FIG. 6 a    is a bottom view of lid  200 . In this exemplary embodiment, lid  200  is of a larger area than the perimeter formed by the rim of chamber  110 . Gasket  240  is disposed within a channel on the bottom surface of lid  200 . The channel may be a square-cut channel for receiving the top rim of the chamber. The dimension of the channel and gasket are of substantially the same thickness as chamber  110 , allowing the proper seal to form. 
       FIGS. 6 b  and 6 c    are a cross section view of a gasket for use in the lid of the receptacle and an isometric view of a gasket for use in the lid of the receptacle. In some embodiments, the gasket may be an X-Ring or a Quad-Ring. The gasket may have four lobes  242 , each lobe having a rounded exterior profile. The four lobes  242  are separated by four concave sides  241 . When the gasket is inserted into the square-cut channel on the bottom surface of the lid and compressed by the top rim of the chamber during tightening of the fasteners, the lobes separated by the concave sides allow the gasket to press into the corners of the channel, increasing the impermeability of the seal. It should be understood, though, that any number of gasket cross sections may provide a sufficient seal to prevent oxidation of the packaged beverage, and the disclosure of the X-Ring or Quad-Ring gasket shape should not be construed as limiting. (The proportion of the gasket in  FIGS. 6 b  and 6 c    is not to scale, but the lobes have been enlarged relative to the diameter of the gasket to better depict the lobes and concave sides.) 
       FIG. 7 a    is a side view of one embodiment of the present invention, as it might be used with a beer growler. This figure shows how tap stem  290  can be placed in beverage package  150 , allowing the stem to reach the sides of the beverage package and pulling more of the beverage than most pump systems allow. 
       FIG. 7 b    is a side of an alternative embodiment of the receptacle. In embodiments where the chamber is long or tall enough to accommodate a two-liter bottle of soda as the beverage package  150 . When a beverage package shorter than a two-liter bottle of soda (such as a growler, as depicted here) is used with such an embodiment, one or more spacers  410  may be used and/or included with the receptacle to ensure the tap stem  290  is long enough to reach into the bottom corner of the beverage package. In different embodiments, the one or more spacers may be height-adjustable via stacking multiple spacers, inflation of the one or more spacers, or other adjustment means. 
       FIG. 8  is a side view of another embodiment of the present invention. In this embodiment, chamber  110  may be comprised of an opaque material, and window  170  may be present to allow a user to see the beverage, and, more specifically, the level or amount of beverage that remains in the package. Window  170  may also allow the user to see which beverage is stored in the receptacle. When chamber  110  is opaque or translucent, rather than transparent, it may allow for decorative elements to be included, such as lights or speakers. 
       FIG. 9  is a side view of one embodiment of the present invention, wherein tap port  280  is coupled with a standard tap  360 . In this depiction, the standard tap is a pump tap, but any number of standard tap systems may be coupled with tap port  280  without altering the function of the present invention.  FIG. 10 a    shows lid  200  with tap port  280  as a ball lock coupler, allowing a user who already has the commonly used ball lock tap system to couple the system with lid  200 .  FIG. 10 b    shows lid  200  with ball lock couplers on both tap port  280  and gas valve  210 , further lending utility to the use of standard ball lock tap systems. 
       FIG. 11  shows an alternative embodiment of the present invention, wherein multiple packaged beverages are disposed inside chamber  110 . In this embodiment, lid  200  still has one gas valve  210 , one pressure relief valve  220 , one pressure gauge port  230 , and one gasket  240 . In a non-limiting example, four bottles  150  are disposed inside chamber  110 , and each bottle has its own tap port  280  and tap stem  290 . Each tap port  280  can be coupled with tap system  300 . This is an exemplary embodiment, and it should not be construed as limiting the number of taps to four. The system may be used with one, two, three, five, or any other number. In some applications, three may be an optimum safe number of packages when factoring pressure loading over a large area. However, a multiple bottle embodiment may contain any number of tap ports and packaged beverages without altering the function of the multiple bottle embodiment. 
       FIG. 12  is a top view of another alternative embodiment of the receptacle. In some embodiments, the receptacle is provisioned with a carrying handle  252 . The carrying handle may be disposed between mounting studs  251 , which are disposed to either side of tap port  280 . In different embodiments, the receptacle may have more than one carrying handle, may include a different type of carrying handle than the swivelable handle, and/or may have one or more handles mounted on a different surface of the receptacle. 
       FIG. 13 a    is an isometric view of an embodiment of the receptacle for storing and preserving packaged beverages.  FIG. 13 b    is a close-up view of a portion of the embodiment depicted in  FIG. 13 a   .  FIG. 13 c    is a side view of a portion of the embodiment depicted in  FIG. 13 a   .  FIG. 13 d    is a top view of an alternate embodiment of a base depicted in  FIG. 13 a   . In some embodiments, the receptacle for storing and preserving packaged beverages may feature one or more elements being located on an alternate base  121  rather than on the lid. For example, one or more of the gas valve  210 , pressure gauge  231  (and its port  230 ), or pressure relief valve  220  may be located on the alternate base  121 . 
     Fasteners  130  (not shown in  FIGS. 13 a -13 d    but depicted in at least  FIG. 1 ) may be removed to make room for the elements relocated to the alternate base. An alternate closure mechanism for the receptacle may be provided (such as the yoke discussed with respect to  FIG. 14 , or another clamping device). In different embodiments, the fasteners may remain and the gas valve, pressure gauge port, and/or pressure relief valve relocated to the base may be offset from the location of the fasteners (i.e. to the side of the fasteners). Moving one or more of the gas valve, pressure gauge (and its port  230 ), or pressure relief valve to the base, leaving only the tap port  280  through the lid, may provide a cleaner appearance for the lid of the receptacle and/or move sensitive instruments such as the pressure gauge to a more protected position between the lid and base. 
     Particularly, alternate base  121  includes passages  123  (depicted in dashed lines in  FIGS. 13 a -13 d   ) through which gas passes from the exterior of the receptacle to its interior. Passages  123  are disposed through the interior of the alternate base  121 , including a portion of each passage which passes underneath channel  122 . At one end, the passages terminate in ports which are disposed on an interior section of the alternate base, such that gas passing through the passages vents into the tube  110  of the receptacle. At opposite ends of the passages are the gas valve, pressure gauge, and pressure relief valve. 
     As may be seen in  FIGS. 13 a -13 d   , the passages  123  permit gas to travel from, for example, the gas valve  210  through the inside of the alternate base  121  along passage  123 , and to vent into the receptacle through gas port  125 . Likewise, upon gas entering the receptacle through the gas port, the pressurization forces gas through port  124  for the pressure relief, then into another passage  123  and to the pressure relief valve  220  where the gas may be vented from the receptacle upon operation of the pressure relief valve. The pressurization also forces gas through port  126  for the pressure gauge, then into another passage  123  and to the pressure gauge port  230 . If a pressure gauge  231  is connected to the pressure gauge port, the pressure inside the receptacle may be read. 
       FIG. 14  is an isometric view of an alternate embodiment of the receptacle for storing and preserving packaged beverages. In some embodiments, a diffuser  610  may be disposed at the end of passage  123 . In such embodiments, gas would come in through the gas valve  210 , flow through passage  123 , and be vented into the receptacle through the diffuser which is inserted into the gas port  125  (not shown in  FIG. 14  but visible at least in FIG.  13   d ). A diffuser emits gas through a plurality of openings or through permeable portions of the diffuser. The surface area through which gas passes to enter the receptacle is increased through use of a diffuser. Via the diffuser, the receptacle would receive a slow and gentle inlet of gas, such as CO2. The resulting reduced mixing of air would allow a better purge of oxygen within the receptacle. 
       FIG. 15 a    is an isometric view of an alternate embodiment of the receptacle for storing and preserving packaged beverages.  FIG. 15 b    is another isometric view of the alternate embodiment depicted in  FIG. 15 a   . It may be desirable to provide an alternate means of closure of the system. For example, rather than the fastener and nut system depicted and described with respect to  FIG. 1 , a yoke or other means of clamping the major elements of the receptacle together may be employed. Receptacle  100  may be placed within a yoke, the yoke including a vertical yoke side  510  which is substantially a similar height to that of tube  110 . In some embodiments, the vertical yoke side  510  has a fixed height. In different embodiments, the vertical yoke side has an adjustable height to accommodate different height tubes and/or growlers. The yoke may include a yoke top  520  which is hingedly coupled with the vertical yoke side via hinge  525 . The yoke may further include yoke bottom  530 , which may be fixedly coupled with the vertical yoke side, or may be hingedly coupled with the vertical yoke side. 
     The yoke top  520  may have a yoke top strap  540  connected at an end of the yoke top opposite the hinge. The yoke bottom  530  may have a yoke bottom strap  550  connected at a corresponding end of the yoke bottom. The yoke top strap and/or the yoke bottom strap may have a closure for securably coupling the top and bottom straps. In some embodiments, the closure may be a ratchet  560 . In other embodiments, the closure may include a turnbuckle, a latch, a fastex buckle, or other mechanism for securably coupling and tightening the top and bottom straps. 
     When inserting a growler or other beverage package into the receptacle, the lid is removed to permit the beverage package to be placed in the tube as described elsewhere herein. Also as described elsewhere herein, lid  200  is placed atop tube  110 . With the instant alternate embodiment, the operation of completing the airtight seal of the enclosure and clamping the lid down over the tube does not utilize the fasteners and nuts described in  FIG. 1  but instead employs the yoke for compressing the lid and tube. As may be seen in  FIG. 15 a   , the receptacle  100  is seated atop the yoke bottom  530  and adjacent to the yoke vertical side  510 . Yoke top  540  is flipped downward in the direction of the arrow and comes to rest atop lid  200 . As may be seen in  FIG. 15 b   , to complete the operation, the yoke top strap and yoke bottom strap are coupled using ratchet  560  (or other closure as appropriate). The strap may be pulled to tighten the lid, compressing the gasket between the lid and tube. To remove a growler or other beverage package, the foregoing steps are completed in reverse. 
     Importantly, while  FIGS. 15 a  and 15 b    depict the yoke in use with an embodiment of the receptacle having the gas valve, pressure relief, and pressure gauge disposed on top of the base, it is intended that the yoke could also be used with embodiments having the three aforementioned elements disposed on the lid (e.g. the embodiment shown in  FIG. 1 ). The construction of the yoke top and lid would be such that the yoke top could be flipped down over the lid without contacting the gas valve, pressure relief, or pressure gauge. 
       FIG. 16 a    is an isometric view of an alternate embodiment of the receptacle for storing and preserving packaged beverages.  FIGS. 16 b  and 16 d    are partial side views of alternate embodiments of the receptacle for storing and preserving packaged beverages.  FIG. 16 c    is a partial perspective view of an alternate embodiment of the receptacle for storing and preserving packaged beverages. In some embodiments, a lid  200  of the vessel  100  may be held in place with a plurality of cam latch arrangements which have been closed in order to apply downward pressure to the lid. In some embodiments, three cam latch arrangements may be utilized; in different embodiments, two, four or any other number of cam latch arrangements are utilized. The number of cam latch arrangements may relate to the number of beverage packages held by the vessel. For example, a vessel similar to that depicted in  FIG. 11  which shows four beverage packages in the vessel may have more than three cam latch arrangements in conjunction with increased tube and lid diameters dictated by the higher capacity of the vessel. 
     A cam latch arrangement may include a column  710  for positioning the remainder of the cam latch arrangement for holding the lid in place upon closure of the cam latch arrangement. In some embodiments, the column may extend from the base  120  of the vessel to a position above the lid of the vessel. In other embodiments, such as that depicted in  FIG. 16 c   , the column may not extend to the base of the vessel providing additional visibility of the beverage package itself and its contents (i.e. through reduced obstruction of the visibility by columns extending to the base). 
     A cam latch arrangement may include a latch, the latch including latch wheel  720  and handle  722 . The latch may pivot about a hinge pin disposed through pivot pin holes  740  of the column and through the latch itself. The hinge pin may be an operating rod molded into the top of the column, or may be a fastener resembling a bolt passed through the pivot pin holes and latch wheel with a nut holding the operating rod in place. The latch also includes a hole for receiving a locking pin. The locking pin of each cam latch arrangement may include a knob attached to a shaft, and a lanyard (chain, nylon, cord, rope or other ligature) may couple the knob to the corresponding column so that the locking pin is not lost or misplaced. 
     To close the cam latch arrangement, the latch is rotated about the hinge pin using the handle, with the handle moving towards the center of the vessel. Upon reaching a closed position, the latch wheel engages the top of the lid, which rests onto top of an o-ring or gasket  780  (o-ring or gasket  780  not visible in  FIG. 16 a   , but a cross-section of the o-ring or gasket is visible between the lid  200  and rabbet  770  or  772  in  FIGS. 16 b  and 16 d   ). The o-ring or gasket is supported by a rabbet  770 . The o-ring or gasket may be adhered to the top of the rabbet, or may be laid in place on top of the rabbet with no adhesive substance keeping it in place. 
     The o-ring or gasket is compressible, such that closure of the latch wheel presses the lid down compressing the o-ring or gasket. In a closed position, a locking pin may be passed through the locking pin holes  730  and through the mating hole in the latch wheel itself to maintain the cam latch arrangement in the closed position. Upon a user removing the locking pin, rotating the latch wheel and handle away from the center of the vessel and releasing downward pressure on the lid, the o-ring or gasket will have a tendency to push the lid in an upward direction. 
     In some embodiments, as shown in  FIG. 16 b   , the rabbet may include a ring along an interior perimeter of the tube  110  of the vessel. In different embodiments, as shown in  FIG. 16 d   , instead of a ring-style rabbet, an extended rabbet  772  upon which an o-ring or gasket would rest may extend downwardly within the interior perimeter of the tube all the way to the base of the receptacle. In some embodiments, the columns, tube, base, rabbet and lid may be individual acrylic components which are solvent welded or otherwise adhered chemically or mechanically (e.g. nuts and bolts) to one another. In different embodiments, the columns, tube, base and rabbet may be a single injection-molded component. 
     The cam latch arrangement facilitates a quicker purge of air from the receptacle than possible with the pressure relief valve  220 . Particularly, the lid may be left slightly open while the gas of the user&#39;s choice is introduced into the chamber. Leaving the lid slightly open may be accomplished by not fully closing one or more of the cam latch arrangements, for example. Upon venting most of the air from the chamber, the user can close the cam latch arrangements tightly and use the pressure relief valve to “fine-tune” the pressurization within the receptacle. 
     In this way, the receptacle for storing and preserving beverages may be provisioned with two means for purging entrained air from the vessel, a “coarse” means via leaving the cam latch arrangements slightly open during when introducing gas into the vessel and a “fine” means via the pressure relief valve used as described elsewhere herein when the cam latch arrangements are fully closed. The partially-open position of one or more cam latch arrangements allows a more liberal purge of oxygen laden air, as there is less resistance than there would be through operation of the pressure relief valve. 
     After an appropriate time of the cam latches being partially open during introduction of gas into the vessel to purge the air (the desired and appropriate time being empirically determined by the user through one or more trials), the cam latch arrangements are closed with the locking pins at which time the pressure relief may be operated to charge the chamber to the desired pressure. Using only the pressure relief means would require a longer amount of time to arrive at the desired pressure; the addition of the cam latch arrangements provides an additional means of controlling a rate of purge of air from the vessel. 
       FIG. 17 a    is an isometric view of an alternate embodiment of the receptacle for storing and preserving packaged beverages. In some embodiments, a conical tap stem assembly  810  may include a plurality of ports permitting connection of two or more gas sources or accessories in addition to the tap tube  830  through which the beverage content passes on its way to the tap port of a ball lock fitting  840  (which tap port may be coupled with a picnic tap, beer faucet or other appropriate dispensing apparatus as disclosed elsewhere herein). As will be discussed below, the conical tap stem assembly may pass through lid  850 , or a lid may be integrated with the conical tap stem assembly. 
     The conical tap stem assembly provides ingress and egress of gas with respect to the vessel  100 . During pressurization of the vessel, gas is emitted from the bottom face of a cone portion  820  of the conical tap stem assembly through a circular port disposed concentrically about the tap stem itself. When purging oxygen-laden air from the vessel via operation of a pressure relief valve coupled with the cone portion, the oxygen passes in the opposite direction through the same circular port (i.e. drawn upward through the bottom face of the cone portion), from the vessel en route to the pressure relief valve. The direction of travel facilitates a more complete purge of oxygen-laden air. 
     Additionally, it may be seen that the cone portion  820  includes the ports disposed through an exterior slanted face surrounding the cone portion. This orientation of the ports allows hoses, tubes and other lumen coupled with the ports to travel upwardly at an angle away from the vessel  100  in a less awkward direction than vertically up or down, reducing strain and stress on such lumen. 
       FIG. 17 b    is an isometric view of a first embodiment of a conical tap stem assembly.  FIG. 17 c    is an exploded cross-sectional view of the first embodiment of the conical tap stem assembly and a lid of the vessel.  FIG. 17 d    is a cross-sectional view of a ball lock adapter component of the first embodiment of the conical tap stem assembly.  FIG. 17 e    is a bottom view of a cone portion of the first embodiment of the conical tap stem assembly.  FIG. 17 f    is a top view of the cone portion of the first embodiment of the conical tap stem assembly. In some embodiments, the conical tap stem assembly  810  includes at least a modified ball lock adapter  860 , a cone portion  820 , a press-fit tap tube  830  and one or more o-rings for sealing the arrangement upon the foregoing components being assembled. 
     As disclosed elsewhere herein, a tap tube may include a combination of rigid and flexible sections enabling the tap tube to reach sides and corners of beverage packages. The appearance of the tap tube may vary as a function of the number or type of rigid of flexible sections (see, for example,  FIGS. 17 b  and 17 c   ). As may be seen in  FIG. 17 c   , the tap tube  830  may have at least a first rigid section  834 , a flexible section  836 , and a second rigid section  838 . The first rigid section is configured for press-fitting into the cone portion by inserting it into the cone portion center shaft  824  and into the ball lock adapter center shaft  864  (ball lock adapter center shaft not visible in the cross sectional view of  FIG. 17 c   , but visible in the cross sectional view of  FIG. 17 d   ). The first rigid section of the tap tube frictionally couples with the interior, concentric center shaft  864  of the ball lock adapter. Importantly, a gap exists between the outer diameter of the tap tube and the inner diameter of the center shaft  824  of the cone portion  820 . Additionally, the outer diameter of the tap tube and inner diameter of the center shaft of the ball lock adapter are substantially the same, with the inner diameter of the center shaft of the ball lock adapter being slightly larger than the outer diameter of the tap tube in order to frictionally receive and retain the tap tube. 
     Referring to  FIG. 17 e   , the aforementioned gap is depicted as  824 . The channel through the tap tube  832  is the innermost concentric circle. Moving towards the outer perimeter of the cone portion, the next concentric circle is the center shaft through the cone portion  824 . The lower threaded portion  829  of the cone portion has a lower face  828  visible in  FIG. 17 e   , and the outermost concentric ring is the bottom face of the cone portion itself which rests on the top face of lid  850 . It may be seen that the gap  824  between the tap tube and the center shaft of the cone portion is sufficiently wide enough for gas to pass through en route in between the vessel and the ports  870 . 
     At the opposite end of the center shaft of the cone section are the ports  870 , shown as  870   a  and  870   b  in  FIGS. 17 b  and 17 c , and 870 a - d    in  FIG. 17 f   . In some embodiments, the cone section may have three, four or more ports. The ports are configured for threadably receiving one or more accessories, including but not limited to couplers for sources of gas, pressure relief valves, pressure gauges, regulators, etc. (such as accessories  880   a  and  880   b ). The ports may be ¼″ or ⅛″ NPT threads facilitating coupling of industry-standard couplings, gauges, reliefs etc. that are well known within the homebrewing and beverage-dispensing communities. The ports are disposed through the slanted face  827  of the cone portion  820 . 
     At the top of ball lock adapter  860  is a threaded section which may threadably receive a ball lock fitting  840 . An o-ring  862  may seal a coupling between the ball lock fitting and ball lock adapter. As disclosed elsewhere herein, the ball lock fitting may facilitate coupling of a picnic tap, beer faucet or other suitable dispensing means to the conical tap stem assembly. Other types of fittings may threaded onto the ball lock adapter to facilitate use with other dispensing systems (e.g. Sankey systems) as needed. 
     The cone portion may include an external threaded portion  829  at its bottom, which threadably mates with a center threaded section  852  disposed through the lid  850 . A lower o-ring  822  of the cone portion creates a seal between the cone portion and the lid. 
     A top face of the cone portion  825  may have a threaded aperture  823  configured for receiving ball lock adapter  860 . A lower portion of the ball lock adapter (i.e. the threaded portion below the hexagonal section  868  of the ball lock adapter) threads into the threaded aperture  823  through the top face  825  of the cone portion. A ball lock adapter lower o-ring  866  creates a seal between the ball lock adapter and the cone section. An off-the-shelf ball lock adapter, commonly used in home brewing, may be employed with a simple modification. Particularly, the center channel through the ball lock adapter  864  is drilled out to widen it for receiving the tap tube during assembly of the conical tap stem assembly. 
       FIG. 18 a    is an isometric view of a second embodiment of a conical tap stem assembly.  FIG. 18 b    is an exploded cross-sectional view of the second embodiment of the conical tap stem assembly and a lid of the vessel.  FIG. 18 c    is a cross-sectional view of the second embodiment of the conical tap stem assembly assembled with the lid of the vessel, the tap tube and the ball lock fitting. In some embodiments, the second embodiment of the conical tap stem assembly  810   b  may be fabricated such that the ball lock adapter and cone portion disclosed with respect to the first embodiment of the conical tap stem assembly are a single integrated component alternate cone portion  820   b , which may be injection molded as one piece, for example. The alternate cone portion,  820   b , includes a threaded portion at its top for threadably receiving ball lock fitting  840 . Other functionality of the alternate cone portion  820   b  is substantially the same as the cone portion of the first embodiment in that it includes a plurality of ports and a threaded portion at the bottom  829   b  for threading the alternate cone portion  820   b  into a lid, for example. The center shaft  824   b  has a shoulder at which the shaft narrows to the same internal diameter of the modified ball lock adapter  860  disclosed with respect to the first embodiment of the tap stem assembly. The foregoing configuration of the center shaft with two different internal diameters facilitates press fitting of the tap tube  830 . An upper o-ring  862  creates a seal between the alternate cone portion  820   b  and a ball lock fitting  840  upon the pieces being threadably coupled; a lower o-ring  822  creates a seal between the alternate cone portion and lid  850  upon the pieces being threadably coupled. 
       FIG. 19 a    is an exploded cross-sectional view of the third embodiment of the conical tap stem assembly with integrated lid for coupling with the vessel.  FIG. 19 b    is a cross-sectional view of the third embodiment of the conical tap stem assembly with integrated lid for coupling with the vessel assembled with the tap tube and ball lock fitting. In some embodiments, the third embodiment of the conical tap stem assembly with integrated lid for coupling with the vessel may be fabricated such that the lid, cone portion and ball lock adapter disclosed with respect to the first embodiment of the conical tap stem assembly are a single integrated component lid/cone  890   c , which may be injection molded as one piece, for example. The cone/lid  890   c  includes a threaded portion at its top for threadably receiving ball lock fitting  840 . Other functionality of the cone/lid  890   c  is substantially the same as the cone portion of the first embodiment in that it includes a plurality of ports. The center shaft  894   c  has a shoulder at which the shaft narrows to the same internal diameter of the modified ball lock adapter  860  disclosed with respect to the first embodiment of the tap stem assembly. The foregoing configuration of the center shaft with two different internal diameters facilitates press fitting of the tap tube  830 . An upper o-ring  862  creates a seal between the cone/lid  890   c  and a ball lock fitting  840  upon the pieces being threadably coupled. 
     In some embodiments, ice may be added to the vessel before the lid is closed for keeping beverages cool. A drain valve may be present, perhaps disposed through the side of the vessel, for draining water resulting from melting ice. Following a draining operation, pressurization inside the vessel may be re-adjusted via applying the gas to the chamber and purging any air having entered the chamber during the draining. 
     While particular aspects of the present subject matter described herein have been shown and described, it will be apparent to those skilled in the art that, based upon the teachings herein, changes and modifications may be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of this subject matter described herein. Furthermore, it is to be understood that the invention is defined by the appended claims. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). 
     While preferred and alternative embodiments of the invention have been illustrated and described, as noted above, many changes can be made without departing from the spirit and scope of the invention. Accordingly, the scope of the invention is not limited by the disclosure of these preferred and alternate embodiments. Instead, the invention should be determined entirely by reference to the claims that follow.
