Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application is a continuation of U.S. patent application Ser. No. 13/364,070, filed Feb. 1, 2012, which is based upon, and claims priority from U.S. provisional application No. 61/438,503 and U.S. provisional application No. 61/438,500, each filed Feb. 1, 2011, the disclosures of which are hereby incorporated by reference in their entireties. 
     
    
     FIELD OF THE DISCLOSURE 
       [0002]    The present invention relates to systems for dispensing wine by the glass or carafe from flexible, collapsible containers while maintaining accurate inventory control and pouring accuracy while minimizing product spoilage and theft. 
       BACKGROUND 
       [0003]    The traditional way of dispensing wine is by the bottle. It is also desirable to be able to sell wine by the glass. This is difficult when wine is packaged in bottles only, because wine is notoriously susceptible to oxygen degradation over a very short period of time. Thus, if a glass of wine is purchased by a buyer, the rest of the bottle will have to be thrown away if it is not consumed in a relatively short period of time of a few hours. The packaging for wine in bottles also presents a substantial cost. 
         [0004]    There have been some developments in apparatus for prolonging the life of a bottle of wine when the wine is served by the glass. In one method, wine is served by the bottle, but the bottles are purged with nitrogen or another non-oxygen gas. These systems provide an extended life of the wine, but generally not more than a few weeks. 
         [0005]    Another problem with dispensing wine by the glass is that it is difficult to control the quantity of wine poured in each glass and make the pourings consistent. Theft and other misuse of the wine is also difficult to track. 
         [0006]    Accordingly, and improved beverage dispensing system for dispensing an environmentally sensitive beverage, such as wine, is desired. 
       BRIEF SUMMARY OF THE DISCLOSURE 
       [0007]    The following presents a simplified summary of the disclosure in order to provide a basic understanding of some aspects of the invention. This summary is not an extensive overview of the invention. It is intended to neither identify key or critical elements of the invention nor delineate the scope of the invention. Its sole purpose is to present some concepts of the invention, in accordance with the disclosure, in a simplified form as a prelude to the more detailed description that is presented later. 
         [0008]    The wine dispensing cabinet of this invention has a number of dispensing taps that dispense a number of different wines from either of two refrigerated compartments. In the preferred embodiment, up to eight wines can be maintained in the cabinet and dispensed from individual nozzles. The cabinets are independently temperature-adjustable, and white wines that are typically served at colder temperatures can be maintained at an appropriate temperature in one of the compartments while red wines can be maintained at a higher temperature in the other compartment. Thus, in a preferred embodiment, eight taps dispense varietal wines including merlot, chardonnay, riesling, cabernet sauvignon, pinot grigio, sauvignon blanc, pinot noir and zinfandel at recommended temperatures. 
         [0009]    The wines are provided to the cabinet in plastic oxygen non-permeable bags enclosed in boxes. Each wine carton is one-third the size of a case of wine in bottles and is approximately half the weight. (Each box weighs approximately 20 pounds compared to a case of bottled wine, which weighs approximately 40 pounds). A spout extends from each bag to a connection fixture at the front of the box, and a connecting tube having a one-way check valve carries wine from the refrigerated compartment to a pump, where portions are measured, recorded, and dispensed to one of the taps. The cabinet uses one or more pumps, and in the preferred embodiment is configured to use a separate pump for each tap. The quantity of wine dispensed can be determined by using a flow meter for each hose, or a single flow meter attached to a single pump; or the quantity can be determined by timing the flow where a constant-flow pump is used. In one embodiment, the dispenser features electronic, automatic portion control: It measures accurate pours of wine in three programmable amounts and records the total ounces poured in each brand of wine for each day as well as the times of each pour. 
         [0010]    Wine from the wine boxes is delivered to the pumps through delivery hoses that are connected to internal hoses that have check valves in the hardware connecting them. Check valves are used to prevent the backflow of wine through the hoses and to prohibit the introduction of air (oxygen) into the lines when they are being attached or detached. 
         [0011]    A bar code is affixed to each box or its label. The bar code has a large capacity for information, and may include the amount of wine contained in the box, the brand and type of wine contained in the box, the identification of each box and the date it is tapped. The bar code can be read by a bar-code scanner that may be detachable or may be built into the wine dispensing cabinet. The wine box then is placed in slot 1 through 8 in the machine. When a new box is placed into a specific slot, a sensor registers the location of the box in the machine and reports that information to a computer, described in greater detail below. The position of the box on the shelf correlates to a specific pump, which will track how much wine is drawn from that box. Thus, the computer identifies the box and its contents when the bar code is scanned, and then the computer identifies the box&#39;s location in the machine via the sensor. This knowledge allows the machine to track each pour from each box via the data processor as the box is drained. If the box should be removed and replaced in a different slot in the compartment, the sensor will alert the computer to the new location, and information regarding that box will be maintained and updated. 
         [0012]    A computer may be included in the wine dispensing cabinet. Where this is done, the computer can be used to perform a variety of functions including: scanning barcodes on wine boxes to determine the type of wine, the supplier, the cost, or other information relevant to the type of wine; recording the amount of wine dispensed from each box; recording and making adjustments to inventory on a daily, weekly, or monthly basis; providing notification when any of the wines need to be restocked; receiving and recording information about customers, such as scanning drivers&#39; licenses and determining the demographics of wine consumption cross-referenced with any of a number of demographic parameters; auditing usage and wastage; and any other information relevant to wine supply and consumption. Daily, weekly and monthly inventories of each brand poured can be determined which pinpoint the most popular brands or varieties poured each day, week or month. Such reports show how many ounces have been poured and compares that data with the wine remaining, providing an accurate, on-time inventory for use by management. The computer stores information obtained from each box&#39;s bar code and from the flow meter assigned to each box. The processor allows a direct PC interface via a cable or through a modem, which can transmit information to an on-premises computer or an off-premises system. 
         [0013]    The dispenser&#39;s computer system utilizes a flow calculation system to monitor the volume of wine the machine dispenses and can be configured to produce cumulative and on-time sales reports by brand and volume. 
         [0014]    When the box is removed, the machine registers its removal and remembers the amount of wine remaining in that box. A partially drained box may be re-scanned and again placed in the machine as much as a year later. When the box is re-scanned, the machine will identify it and remember which slot it originally was in. The computer will also recall how much wine the box should hold when it is replaced in the dispenser. If the box contains a different amount of wine than the computer remembers, the computer will report that information in the daily printout, which will apprise management that someone may have tampered with the box. 
         [0015]    An optional driver&#39;s license scanner scans the face of a driver&#39;s license and captures demographic information, including name, age, sex and address. The information is uploaded to a fully customizable, multifunctional database that allows the operator to track consumption according to this information. This data allows the operator to identify and capitalize on customers&#39; preferences. The system features a fully customizable, multifunctional database that includes easy sorting of data, advanced search options and easy data export. The search option allows users to filter data by any field, including name, address, sex and birth date. This information is uploaded to the computer system, where it can be analyzed according to the brand and variety poured for each customer, allowing the user to track popular brands and varieties of wine according to age, sex, address, and other point-of-sale (POS) information. 
         [0016]    The computer may send POS information through a modem to off-premises locations as well as supplying information to the on-site computer. In this manner, the invention provides effective bar controls, prevents theft, and manages a large wine inventory without increasing the load on the management team. 
         [0017]    The computer can also be programmed either to shut off pouring or indicate in the daily report when a box has been tampered with. The shut-off is the machine&#39;s default response to a box that contains less wine than it should. During normal operation, a box of wine is scanned by barcode and placed on the shelf. The machine, through its sensors, knows where in the machine the box is placed and tracks how much wine is removed from the box. The operator can remove and then re-scan and replace the box in any of the eight locations. The machine picks up exactly where it left off the last time it saw that particular box. If the total volume from that box is less than the recorded volume that&#39;s in the computer (with some margin), the machine can be programmed to shut off that pumping station. This is a programmable feature and the machine can respond in any number of ways to this situation. The owner may not desire a stoppage and instead it may only log the disparity in the daily report and continue dispensing. 
         [0018]    The computer may also be configured to allow for customer self-serve operations. In one embodiment, a credit card reader is provided which allows patrons to purchase a glass of wine from the wine dispenser and serve themselves. This eliminates the necessity of a staff member running the machine. 
         [0019]    The dispensing cart is easily movable, having at least 4 swivel rollers and a 360-degree turn radius, and is suitable for use in hotels and other semi-public facilities. The cabinet is constructed of commercial stainless steel and features a high-visibility, full-width display of available wines in their bottles, allowing customers to view potential selections prior to ordering. 
         [0020]    The wine dispensing system can be operated from an external electrical power supply or using an optional rechargeable lithium battery. The unit can operate on battery power with the exception of the refrigerators, which will maintain temperature without power for approximately 3 hours. Thereafter, the operator only must plug the unit in to restore temperature or replace the wine with pre-chilled boxes. The dispenser can hold 8 cases of wine at one time, ensuring that additional chilled storage rarely is needed. 
         [0021]    The wine dispensing machine of this invention enables customers to create their own wine blends in states that allow it. In this embodiment, customers would purchase re-usable glass bottles that are sandblasted with a proprietary, universal, pre-approved label, an individual&#39;s label or a winery&#39;s existing label. The wine bar provides a variety of wines and the necessary accoutrements for blending. Customers can create their own blends, and can record the percentages of each brand and variety. When the customer is satisfied with his or her blend, the percentage of each wine variety used can be recorded by the computer, where it will be kept on file for future bottling purposes. The system blends the customer&#39;s recipe and bottles it, then places the bottles into a 6-bottle wine carrier. The blending feature of the invention is suitable for use by individual customers, by restaurants, or by wine distributors or wholesalers. 
         [0022]    Foreign wineries that wish to export their product to the United States have a difficult time obtaining representation. They first must convince a federal importer to import wine in the hopes a state importer and wholesaler will buy it and are able to sell it to a retailer. Small wineries don&#39;t interest wholesalers, who are interested in volume. Furthermore, the foreign winery must obtain federal and state label approval in accordance with TTB and state liquor control requirements. The foreign winery then must produce the wine, bottle the wine, label the wine and ship cases of the wine to the United States before they have a sale. Small foreign wineries are faced with a huge expense if the wine is not accepted by state importers, wholesalers or retailers. Smaller wineries cannot afford this risk. As a result, many small estates are hindered from entering the U.S. market. Additionally, both the small and larger wineries face uncertainty as to how their wines will be accepted in the U.S. market. The wine dispenser of the present invention solves this problem. The exporting winery must produce only a few containers of wine, and can ship it to a U.S. seller bearing a pre-approved universal label. The wholesaler can obtain the wines directly from Emerald&#39;s importer division, and then take the boxes directly to its proposed customers or to restaurant shows, where it can determine interest directly from restaurateurs who could place orders for the wine. The wholesaler would have all the information to make a sale—price, label, source of origin, etc. The restaurateurs would rate the wine they tasted and this information would provide the wholesaler with information regarding customer interest. Customers could taste the wines and provide their opinions to the restaurateur or retailer. These wines could be dispensed as tasting wines at no charge to the customer, saving on federal and state wine taxes. This would be done at a minimum cost to the exporting winery. This process would allow small foreign wineries to determine whether their wines are accepted in the U.S. market without incurring unnecessary expenses and risks.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0052]    The following detailed description and the appended drawings describe and illustrate some embodiments of the invention for the purpose of enabling one of ordinary skill in the relevant art to make and use the invention. As such, the detailed description and illustration of these embodiments are purely illustrative in nature and are in no way intended to limit the scope of the invention, or its protection, in any manner. It should also be understood that the drawings are not to scale and in certain instances details have been omitted, which are not necessary for an understanding of the present invention, such as details of fabrication and assembly. In the accompanying drawings, like numerals represent like components. 
         [0053]    Referring now to  FIGS. 1 and 2 , a wine dispenser constructed in accordance with the present invention comprises a stainless steel cabinet  12  mounted on wheels  14 . The cabinet has an enclosed lower portion having an interior enclosed by hinged doors  20 . The interior of the cabinet includes a number of storage receptacles  22  for retaining box wine containers  54 . The interior of the cabinet also includes refrigeration equipment or other temperature control apparatus for maintaining one or more desirable temperatures in the interior of the cabinet. 
         [0054]    The upper surface of the cabinet includes a countertop  26  at the front of the cabinet, and a drain panel  28  at the rear of the countertop for draining liquids or spillage from the counter. In one embodiment, a foldable end panel  30  is mounted on at least one side of the cabinet and can be raised to a horizontal position, as shown in  FIG. 2 , to serve as additional countertop surface. Alternatively, the panel can be folded downward into the side of the cabinet when not in use. 
         [0055]    In a preferred embodiment, a wine dispensing housing is mounted on a rear portion of the cabinet and includes a vertical housing  34  extending upwardly from a rear side of the countertop and a forwardly extending dispenser housing  36  extending forwardly from the vertical housing. The vertical housing  34  serves as a display case to show bottles  42  representative of the wines being dispensed from boxes in the cabinet, with the vertical panel having a transparent panel at the front and an open interior behind the transparent panel for displaying bottles of wine. 
         [0056]      FIG. 3  shows a number of wine boxes  54  mounted in a refrigerated compartment  22  of the wine dispensing cabinet. When properly installed and connected, delivery hose  60  is attached to connector  62 , and wine can be drawn from the box to the pump, and will be further dispensed into a glass. Delivery hose  60  is attached to internal hoses in the cabinet through a connector  70  that has an internal check valve. When delivery hose  60  is disconnected from the internal hosing, the check valve prevents wine from backflowing out of the connector and prevents air from entering into the cabinet hose. 
         [0057]    One embodiment of the front panel  52  of the forwardly extending dispenser housing  36  is shown in  FIG. 4 . In a preferred embodiment, for each type of wine there are three automated choices that dispense varying quantities, namely a sample size, a normal size, and a large size. Persons of ordinary skill in the art will recognize that the number of choices and the amount of wine dispensed for each choice are not limited to those disclosed in the preferred embodiment. Also visible in  FIG. 4  are the dispensing nozzles  48  from which wine is dispensed, and beneath which a wine glass will be placed to receive the wine. Representative bottles  42  are placed in a display area  40  to provide a visual indication of the kind of wine that will be dispensed from each nozzle  48 . 
         [0058]    Wine is dispensed in the present invention by button operated switches  50  mounted on a front panel  52  of the dispenser housing  36 . In the preferred embodiment, the switches include three buttons that are preferably color coded and/or marked to represent different portion sizes. Each button actuates a timer that will cause the dispensing pump to operate for a precise period of time. Since the pump is a positive displacement pump, the amount of time that the pump is operated is used to precisely control the amount of liquid that is dispensed. By calibrating the pump with the time of operation, a precise pour amount can be determined for each operating button. 
         [0059]    Operating buttons  50  can be programmed to operate for a predetermined period of time when depressed momentarily, or can be programmed to dispense in other ways. For example, the system could require that the button be continuously depressed to continue dispensing. This might prevent inadvertent spills. Alternatively, the system could provide for termination of an automatic pouring sequence by depressing multiple buttons simultaneously, for example. 
         [0060]    In the illustrated embodiment, three separate buttons  50  are provided for each dispensing station. One button might be for a sample pour. Another might be for a one-half pour, and the other might be for a full pour. The number of ounces in each pour can be determined precisely, so that no overpouring or underpouring is done. 
         [0061]    While a timed pump cycle is effective in controlling the portions poured, other portion control measures are known and could be employed. For example, a digital flow control mechanism responsive to the flow of liquid through a delivery tube could be employed to control the operation of the dispenser. Alternatively, the flow of wine may be metered, and the system configured to stop dispensing once a predetermined quantity of wine has been dispensed. 
         [0062]      FIG. 5  depicts another embodiment of the front panel  52  of the forwardly extending dispenser housing  36 . A top  38  may be removable, or may be hinged to allow access into the forwardly extending housing.  FIG. 5  also shows a drain panel  28  built into countertop  26  whereby wine spills may be collected and cleanup can easily be performed. In this embodiment, buttons  50  on front panel  52  are arranged horizontally, rather than vertically. 
         [0063]    As shown in  FIG. 6 , top  38  opens to provide access to the interior of the forwardly extending vertical housing  36 , so that representative wine bottles  42  can be placed into and removed from the display area  40 . The interior of the front portion of dispenser housing  36  includes individual wine dispensers  44  located in the interior of the dispenser housing. Wine dispensers  44  include positive displacement pumps  46  that pump wine from each of the wine containers  54  to separate outlet nozzles  48  spaced along the underside of dispenser housing  36 . Pumps  46  dispense a predictable, measured amount of liquid per unit time of operation. Thus, the amount of time the pump is operated can precisely control the amount of liquid dispensed. Such pumps are conventional. Peristaltic pumps may be used to draw the wine from the wine containers, and use an electric motor to turn a set of rollers, which compress and release flexible tubing as they rotate. This squeezing action creates a vacuum that draws fluid through the tubing. A solenoid valve maintains the vacuum when the pump is idle. As the pumps draw wine from the wine containers, the wine containers are deflated, ensuring wine is not displaced by oxygen. In addition, the peristaltic pump helps prevent contamination because the wine being pumped remains inside the tubing at all times and never comes in contact with any pump gears, seals, diaphragms, or other moving parts. While separate pumps for each wine variety in each outlet nozzle are illustrated in the present invention, it is contemplated that one pump, appropriately connected to the wine delivery tubes, could serve to pump the wine dispensers. By way of illustration, tubing may be utilized that contains an inner liner surrounded by a seamless extruded barrier. The inner liner preferably offers permeation resistance to flavors and gases and is certified under standard NSF-51 for food equipment and NSF-61 for drinking water systems. Tubing may be used that has a permeability coefficient of 200 and complies fully with the requirements of USP Class VI, European Pharmacopeia 3.2.9 and FDA 
         [0064]    All tubing connection points in the unit may feature a smooth inner bore fitting. A connection between tubing and a conventional fitting with a blunt end can create a dead spot in the flow path where the blunt end of the fitting and the tubing interface, and fluids can collect in this dead spot. Conversely, a smooth inner bore fitting, when used in conjunction with a retainer, for example a BarbLock, may be used to form a compression seal between the fitting and the tubing that eliminates the dead spot in the flow path. This helps prevent bacterial growth and ensure a consistent flow. 
         [0065]      FIG. 7  depicts the interior of the forwardly extending dispenser housing  36  of the wine dispensing housing  32 . Individual wine dispensing units  44  include positive displacement pumps  46  located in the interior and connected to outlet nozzles that extend downwardly through the housing. Upon being activated by the pressing of a wine selection button  50 , the associated pump will begin pumping wine to the associated outlet nozzle until the desired amount of wine has been poured. Although the preferred embodiment uses positive displacement pumps that dispense a known quantity of fluid per unit of time, other pumps may be suitable for the invention, and other means for measuring quantities being dispensed may be used. In addition, a manual activation button may be used that will activate the pump for as long as the button is held down, thereby permitting the dispensing of wine in quantities other than those automatically dispensed in accordance with predetermined criteria. 
         [0066]      FIG. 8  shows a wine box  54  having a wine box outlet fitting  58  that connects to delivery hose  60  with a connector  62  that interfaces with connector  58  to form a right angle connection. The wine box  54  is being inserted into a refrigerated storage receptacle  22 . The wine containers  54  of the present invention include a flexible, collapsible interior container contained in a rigid shell or box. These products are known and are commonly referred to as “bag-in-a-box” containers. The advantage of these containers is that they are inexpensive, can hold up to a case of wine in one container, and will preserve the wine in a substantially oxygen free environment, so that the wine can remain fresh for up to twelve months. Conventional wine in a bottle is very susceptible to oxidation and can deteriorate substantially in a short period of hours or days. 
         [0067]    It is known to package wine in this manner. However, the outlet valve for such containers can be problematic. In a typical bag-in-box wine container, an outlet valve mounted in the side of the container typically has a connector opening that is aligned with the interior of the container. A spigot connector or delivery tube connector typically is connected to the box outlet by pushing the connector inwardly against the side of the box. If the connector does not latch readily or if the connector is pushed too hard, the connector on the side of the box can be pushed inwardly inside the box and is thus inaccessible. 
         [0068]    In the present invention, an improved connector such as, but not limited to, the improved connector disclosed in my co-pending patent application 61/438,500, filed Feb. 1, 2011, overcomes this problem. 
         [0069]    Referring to  FIGS. 8 and 9 , wine container  54  comprises a box which may be formed of cardboard or other conventional material. This box will be installed inside the refrigerated wine storage compartment  22 . A box outlet fitting  58  is mounted in the side of the box. Outlet fitting  58  attaches to a connector  62  on a delivery hose  60  to form a right angle connection, such that wine flows out of the box and then turns at a right angle in fitting  58 . The wine dispenser is connected to box  54  by a delivery hose  60  that has a connector  62  on the end. The connection between delivery hose  60  and the internal hosing in the cabinet incorporates a check valve  70  to prevent wine from flowing backward, out of the cabinet, and to prevent air or oxygen from entering the cabinet hosing. 
         [0070]      FIG. 10  depicts three embodiments of connectors  62  that will form a right angle attachment when connected to wine box outlet fitting  58 .  FIG. 10A  is an embodiment in which a check valve  68  is incorporated into the connector  62 . Connector  62  forms a right angle connection with wine box fitting  58 , as shown in  FIG. 8 , and is also connected to delivery hose  60 . Delivery hose  60  is a short hose that connects to other internal hoses within the wine dispensing cabinet. As shown in  FIG. 10 , delivery hoses  60  may have different connectors  62  at one end where connections are made to wine box outlet fittings  58 . This permits the wine dispensing cabinet to use box wines from different wine producers having differently configured outlet fittings  58 . However, delivery hoses  60  have identical fittings  64  at the end opposite the wine box connectors, where the hoses attached to the wine dispensing cabinet. Fittings  64  have an inner end connector and an O-ring seal  66  that are received into sockets in the internal hoses of the wine dispensing cabinet. Each socket has an additional check valve that is pushed opened when contacted by fitting  64 . Check valve  70  prevents wine or air from backward flow through the system, and protects unused wine from oxygen deterioration. In this manner, when wine boxes are changed, no air will enter the system, and wine in boxes being removed will remain fresh and can be reinstalled at a later time with no degradation in the wine quality. 
         [0071]      FIGS. 10B and 10C  depict industry-standard connectors that interface with wine box outlet fittings  58 . All connectors form a connection that is at right angles to the box outlet fitting  58 , thereby relieving stress on wine box outlet fitting  58  to avoid pushing it backwards into the box during installation. 
         [0072]    Another feature of the wine box container of the present invention is that the container is especially resistant to oxygen infiltration and therefore is able to preserve wine for up to twelve months. Check valves permit wine to be withdrawn from the container by vacuum, and prohibit the infiltration of oxygen into the flexible container. Check valves placed in the outlet fitting of the flexible container of the wine box permit the positive displacement pump to withdraw wine from the box and collapse the flexible container by applying an vacuum when wine is being dispensed. However, if the vacuum is discontinued, the check valve closes, and no oxygen will enter the container. 
         [0073]    Another feature that makes the wine container of the present invention less permeable is the application of an oxygen resistant coating to the flexible container, which is usually a plastic bag. The oxygen resistant coating is a substance commonly referred to as EVOH (Ethylene Vinyl Alcohol). This provides an oxygen barrier for improved packaging and shelf life of the wine. 
         [0074]    In another embodiment of the present invention, the wine boxes are provided with a computer readable bar code that contains all of the relevant information about the wine contained in the box, including the identity of the wine and any other relevant information that might be desired about the wine or the customer. The bar code can be a two or three dimensional bar code, or can be any other suitable medium that can be scanned or sensed by an appropriate scanner or sensor. The wine dispenser itself includes a bar code scanner or sensor that reads the bar code whenever a box is installed in the wine dispenser. Thus, the wine dispenser knows what wine was installed, in what storage receptacle the wine is located, when installation occurred, and how much wine is contained in the box. This information is transmitted to an internal or external (or both) computer controller. The computer controller also receives input from the pumps, dispenser nozzles, or other measuring device, and thus keeps track of the amount of wine dispensed through each nozzle. The computer controls also can receive information from a credit card reader or other payment medium in order to keep track of the payments received and compare them with quantities of wine dispensed. This computer information can be made available to the onsite operator of the wine dispenser. Also, the same information can be transmitted wirelessly or in any other conventional way to an offsite control center, where the wine dispensing systems of one or many wine dispensers can be monitored. 
         [0075]      FIG. 11  depicts one embodiment of a computer display that may be attached to, or used at or near the wine dispensing cabinet to give real time information regarding the status of the cabinet. Through such an interface, pour quantities may be established, diagnostic tests may be performed, installed wine boxes may be identified, and other desired information can be monitored or modified. 
         [0076]    Referring now to  FIGS. 12-13 , the wine container  24  comprises a box  54 , which may be formed of cardboard or other conventional material. This box is housed inside the wine storage compartment  22 . A box outlet fitting is mounted on the side of the box. The outlet fitting has a right angle connector at an outer end, such that wine flows out of the box and then turns at a right angle in fitting  58 . The wine dispenser is connected to a box  54  by a delivery tube  60  that has a connector  62  on the end. The connector  62  ( FIG. 12 ) has an inner end  64  with an O-ring seal  66  on the end thereof that fits into the right angle connector  58  in the box outlet. Thus, when the tube connector  62  is connected to the box, the thrust is at right angles to the box and does not force the box outlet valve into the box. Preferably, quick-coupling connectors are utilized that are composed of Acetal, and contain an integral check valve that ensures oxygen does not enter the bag. 
         [0077]    As illustrated in  FIG. 14 , an external side view of an exemplar embodiment of the trifunction dispensing tap  100  comprises valve cap  200 , a tap body  300 , and a sealing means  400 . Sealing means may be O-ring seal  66 . Tap body  300  serves to be the intermediary which allows fluids to transfer from a bag-in-box reservoir  101  to the dispensing container or dispensing conduit  102 . The tap body is preferably integrally molded from a thermoplastic resin such as polyethylene or polypropylene, but can be molded from numerous materials such as rigid polyurethane, acetal, polyphenylene oxide, polyester, polyamide, polyphenylene sulphide, polyethylene terephthalate, ABS, polycarbonate, and polysulphone. Numerous criteria are considered when choosing a polymer such as cost, ease of molding, oxygen permeability, flexibility, strength, chemical resistance, and operational temperature. Polyolefins such as polypropylene and polyethylene are commonly used for similar types of single-method dispensing taps. It is of particular interest that a resin be chosen for its structural behavior near or below freezing temperatures. Polypropylene becomes very brittle at these temperatures and can shatter like glass if stressed while at or below freezing temperatures, but has good strength and rigidity at above freezing temperatures, which is desirable. High density polyolefins can approach the stiffness of polypropylene but will not become brittle when subjected to freezing conditions, therefore HDPE is presently preferred. Valve cap  200  is preferably integrally molded from a thermoplastic resin similar to tap body  100 . However, it is desirable to choose a lower density polyethylene, such as LDPE so as to from a variety of low durometer elastomeric materials such as Butyl, Buna-N, EPDM, Nitrile, Silicone, Neoprene, or Viton. A primary consideration is given to the material&#39;s low-cost performance given the particular fluid&#39;s chemical characteristics. Given these considerations, 70-80 durometer EPDM is a practical choice for fluids such as wine. Tap body  300  comprises inlet end geometry  301  to sealingly adapt to gland fitment which is welded to and part of the bag-in-box reservoir. The gland is typically made from HPDE and has a hollow bore such that tap body lead-in feature  306  (shown in  FIGS. 6 and 8 ) can press into and deform the gland bore slightly as the tap body is inserted up to the depth of the limit flange  302 . As tap body  100  is inserted, the at least one sealing rib  304  makes a liquid-tight seal from the tap body  100  to the gland bore. Tap body  100  has a dispensing outlet  305  which serves to direct fluid exiting the tap and allows a connection means to a suitable receivably engaging adapter  500 . Dispensing outlet  305  has a groove to accept sealing means  400 , which may be a rubber or plastic gasket or any other suitable O-ring known in the art, and provides for a retention feature  311  to secure the adapter  500 . 
         [0078]      FIG. 15  illustrates exemplar embodiment of tri-function dispensing tap  100  as seen from the front, its three components shown assembled. Sealing means  400  can be integrally molded into tap body  300  in the form of sealing ribs or even over-molded with an elastomeric material making the tap body  100  integral with its external sealing means  400 . 
         [0079]      FIG. 16  illustrates the tri-method dispensing tap  100  as seen from the top. The valve cap  200  is shown with a fluted hand knob whose large diameter and, in the embodiment depicted in  FIG. 16 , deep depressions  201  provide substantial hand gripping contact forces to twist the knob clockwise to close, and anti-clockwise to open. The direction of rotation of valve cap  200  to open the valve is a matter of design choice, and may be either direction. Directional indicator  202  is molded into the valve cap  200  knob such that the direction and flow amount are symbolized in an increasing width curved arrow. As the arrow is curving anti-clockwise and growing larger, the corresponding flow rate becomes greater. The view from section line B-B is shown in  FIG. 6 . 
         [0080]      FIG. 17  illustrates an embodiment of the tri-method dispensing tap  100  as seen from the side with receivably engaging adapter  500  attached. Adapter  500  depicts a generic variety of connector with a female socket  507  and a male hose barb  502 . Adapter body  501  provides features for lockingly engaging tap body dispensing outlet  305  by actuating quick-release button  504 . Sealing means  400  provides for a radial compression seal with adapter socket  507  as shown on  FIGS. 5 and 6 . Tap body  300  is provided with at least one rotational engaging means  310  such as a helical thread, bayonet tab, cam boss, or the like. Tap body window  311  is useful in injection molding to provide for a moldable feature such as the cam boss depicted for rotational engaging means  310 . 
         [0081]      FIG. 18  illustrates the tri-function dispensing tap in cross-section A-A, taken from  FIG. 17 . Adapter  500  is shown as attached and locked in place with sealing means  400  shown as compressed in a radial fashion between adapter socket  507  and dispensing outlet  305 . Adapter  500  has exit port  503  for providing a leakproof outlet for fluid flow. Typically, adapter  500  is attached to a flexible tube via the male hose barb  502 . Additionally,  FIG. 5  shows the valve cap rotational engaging means  205  in communication with tap body rotational engaging means  310 . The at least one valve cap rotational engaging means  205  is depicted herein as a cam track which provides for a helical path imparting vertical or axial motion when valve cap  200  is undergoing rotation. When the valve cap rotational engaging means  205  are rotated anti-clockwise against the static cam boss  310 , the valve cap ascends outward and upward. Any features such as a helical thread, bayonet tab, cam track, boss, or the like are preferably limited to provide the necessary valve lift within 90 to 180 degrees of rotation and preferably no more than 90 degrees to allow quick, easy, and intuitive ¼ turn valve operation. Valve seat  204  rotates and descends into tap body seal  308 . Seal  308  is configured to provide for a deforming leak-tight fitment to valve seat  204 . 
         [0082]      FIG. 18  illustrates the tri-function dispensing tap  100  in a cross-section B-B from  FIG. 16 . This view shows the fluid path  101  as it comes from the bag-in-box reservoir into tap body inlet  306 . Fluid from tap body inlet  306  passes into transition region  307  where the fluid stops until valve seat means  204  lifts off of tap body seal means  308  thereby opening the tri-function dispensing tap valve. Fluid then flows through tap body outlet  309  and into a drinking vessel. 
         [0083]    Alternately, tap body outlet  309  allows fluid to flow into adapter  500  as shown, wherein the fluid is then transported via flexible conduit for remote dispensing. Adapter  500  incorporates a spring element  506  which allows for simple push-on engagement and leak-tight connection and which requires an overriding force in latch button  504  to release adapter  500  from tap body retention feature  311 . 
         [0084]      FIG. 20  illustrates the tri-method dispensing tap in an isometric view and depicts overall appearance and integration of the main components valve cap  200 , tap body  300 , and adapter  500 . 
         [0085]      FIG. 21  illustrates the tri-function dispensing tap  100  in an exploded isometric arrangement and shows greater detail of the internal tap body static cam boss  310  and valve cap rotational engaging means  205 . It can be seen that valve cap rotational engaging means  205  has a chamfered notch  206  to allow for initial assembly of the valve cap  200  into the tap body  300 . The chamfered notch  206  allows for the valve cap to deform and jump past the tap body cam boss  310  as it is inserted during assembly. Once Cam boss  310  has jumped past notch  206 , the cam boss  310  is seated securely and permanently into cam track  205 . Cam track  205  can have additional features such as a ramps or a detent to give a tactile feel and locking means to prevent valve cap  200  from gradually rotating open by itself and requires an extra bit of twisting force to initiate the opening of the valve during twisting. Valve cap  200  has integral sealing means  207  which seals the valve cap  200  into the tap body smaller inner bore  312 . Stiffing rib  313  adds considerable strength to tri-function dispensing tap  100  particularly when large side loads are placed onto the tap body  300  from undesirable tugging on the tube. 
         [0086]      FIG. 22  depicts another embodiment of the tap of this invention in which a compression spring  602  is used to press valve  600  (shown in detail in  FIG. 10 ) downward to shut off the flow of liquid when valve cap  200  is in the closed position. In this embodiment, valve  600  has an upper portion  606  that acts as a valve stem and that is raised (opened) or lowered (closed) as valve cap  200  is manually opened or closed, and a lower portion  604  that has passageways through which liquid may flow when the valve is open. 
         [0087]      FIGS. 23 and 24  provide detailed views of valve  600 . An upper portion, valve stem  606 , comprises two resilient fingers  610 , each of which terminates in an outwardly-facing barb  608 . The resilient fingers  610  and outwardly-facing barbs  608  permit easy assembly of the tap, in which valve  600  may be inserted from the bottom of the tap through exit port  309  simply by squeezing resilient fingers  610 , which will snap back after insertion to hold valve  600  within the tap. Barbs  608  fit through and spring back against internal ridge  208  which runs circumferentially around the interior cavity of valve cap  200 . Once installed, barbs  608  rest against the upper lip of internal ridge  208  such that, when valve cap  200  is raised to an open position, barbs  608  and resilient fingers  610  are raised to lift the lower portion of valve  604  into the open position. 
         [0088]    The lower portion of valve  600  is a hollow cylinder  604  that has four openings, or windows  612 , through which wine or other liquid will flow when the valve is in the raised, or open, position. Above windows  612  is a groove  614  to receive an elastomeric seal which may be in the form of an O-ring about valve  600 . When the valve is in the lowered, or closed, position, the elastomeric seal will contact the lower, funnel shaped portion of the tap, to create a seal that prevents fluid from flowing through the tap. Above groove  614  is a cylindrical base  616  which supports valve stem  606  and provides a platform to support the lower end of compression spring  602 . 
         [0089]      FIG. 25  is a right sectional view of the embodiment shown in  FIG. 9 , with the valve in an open position. Spring  602  winds helically about valve stem  606  between cylindrical base  616  and the lower surface of ridge  208 , previously described as an internal ridge running circumferentially about an interior cavity in valve cap  200 .  FIG. 12  also shows an elastomeric sealing means  618 , which may be an O-ring or any other suitable sealing means, seated within groove  614 . Wine or other liquid situated in transition region  307  can now flow through the tap following liquid path  702 . 
         [0090]      FIG. 26  is a sectional perspective view showing the tap of  FIG. 9  in a closed position and ready to receive automatic dispensing adapter  500 . Sealing means  618  is resting against the lower portion of the internal passage through the tap and prevents liquid from flowing through the tap. Valve cap  200  is in a lowered, closed, position, and spring  602  is pressing against internal ridge  208  and cylindrical base  616 , forcing valve  200  to a lowered position. 
         [0091]      FIG. 27  is a right sectional view of the configuration shown in  FIG. 13 , and shows tap  300  in a manually closed position and ready to receive automatic dispensing adapter  500 . Sealing means  400 , located at the outer surface of dispensing outlet  305  will be received in connecting socket  507  of automatic dispensing adapter  500 . Connecting socket  507  has a shoulder  508  adapted to receive the lower end of valve  604  such that, when automatic dispensing adapter  500  is snugly attached to dispensing outlet  305 , valve  604  will be pushed upward to the open position, and fluid passageway  702  will open, regardless of the position of valve cap  200 . This configuration is depicted in  FIG. 28 , in which the lower end of valve  604  is resting upon shoulder  508 , which has caused valve  604  to move upward, compressing compression spring  602 . 
         [0092]      FIG. 29  shows tap  300  connected to automatic dispensing adapter  500  to create fluid passageway  702 . The upward movement of valve  604  has also raised valve stem  606  and barbs  608  have moved to a position above internal ridge  208 . In this configuration, the flow of wine or other fluid will be controlled by an external pump or other mechanism attached to the distal end of a tube (not shown) whose proximal end will be attached to hose barb  502 . 
         [0093]    It will be appreciated that the embodiment of tap  300  depicted in  FIGS. 9-16  will always be forced open when automatic dispensing adapter  500  is attached, regardless of the manually selected position of valve cap  200 . When automatic dispensing adapter  500  is released through quick fitting mechanism  504 ,  506 , wine or other liquid may continue to flow unless valve cap  200  has been manually set to the closed position. 
         [0094]    The tap of this invention may be used with automatic filling machinery to fill bladders with liquid such that minimal or no leakage occurs, and the filled bladders may be packaged for transportation and shipment. The embodiment of  FIGS. 9-16  is particularly well suited for automated filling since the fluid path  702  is opened merely by pressing valve  604  into the tap, and fluid may then be injected into the bladder. Once filling is complete, the filling machinery may remove oxygen or ambient air, and may inject nitrogen or some other suitable gas into the bladder to equalize air pressure and prevent or reduce the introduction of oxygen into the bladder through permeation of the bladder surface. As no manual manipulation of valve cap  200  is required for such a filling procedure, the process may be automated, and the efficiency of the process will be enhanced. 
         [0095]    The tap of this invention permits wine or other liquid to be dispensed manually or through the use of an automated dispensing apparatus. Regardless of the method used, oxygen does not come into contact with liquid that remains in the bladder, which may be preserved indefinitely without deterioration. 
         [0096]    Another feature of the wine box containers of the present invention is that they are larger than typically normal, holding about nine liters or one case of wine. This provides packaging and expense advantages. 
         [0097]    In addition to monitoring operations in order to confirm that all wine dispensed has been properly accounted for, the computer monitoring operation can monitor consumer wine preferences and the amount of wine consumed and can be connected to an automatic ordering system that insures that inventory will always be on hand when needed.
