This application claims benefit of provisional application Ser. No. 61/277,125, filed Sep. 21, 2009. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates to beverage dispensing systems, and in particular to a product storage and handling system for a beverage dispenser, which accommodate convenient storage and replacement of separate disposable containers of liquid beverage components to be delivered to beverage valves of a beverage dispenser. 
     BACKGROUND OF THE INVENTION 
     Product dispensing systems, such as beverage or drink dispensers, have supplies or containers of liquid beverage components fluid coupled to dispense valves for mixing and dispensing of drinks for service to customers. The beverage components may comprise beverage concentrates or syrups, along with one or more liquid diluents for mixture with the concentrates or syrups to provide a desired beverage. The beverage components are desirably chilled, so that a cold drink drawn from the dispenser for service to a customer is not warm and degraded in quality by excessive melting of ice. Chilling of the beverage components can be accomplished in any suitable manner, such as by refrigerating an interior of a cabinet in which the supply containers are maintained or by flowing the beverage components through a cold plate as they are delivered to the beverage dispensing valves. The supplies of liquid beverage components may be located either near or remote from the dispenser and the components are delivered by pumps through fluid supply lines from the supplies to individual ones of a plurality of beverage valves of a dispenser. One such beverage dispenser of a type having dispense valves for being fluid coupled to supplies of liquid beverage components is taught by U.S. Pat. No. 6,935,532, the teachings of which are incorporated herein by reference. 
     When a liquid beverage component supply container is depleted, it is replaced with a fresh supply container. Replacement requires that the fluid connection of its associated fluid supply line be removed and then reconnected to the fresh supply container, which removal and replacement of the fluid connection and container can be tedious and time consuming when the supply containers are stored, as is usually the case, in close proximity to one another within a cabinet. 
     OBJECT OF THE INVENTION 
     A primary object of the present invention is to provide a beverage component storage and handling system for a beverage dispenser, which accommodates convenient storage and replacement of disposable containers of liquid beverage components that are fluid coupled to dispense valves of a beverage dispenser.

     DETAILED DESCRIPTION 
     As seen in  FIG. 1 , within a cabinet  20  is a plurality of supply containers or bags  22  (see  FIG. 6 ) of liquid beverage components that are each disposed in an associated one of a plurality of bins  24  carried on sliding shelves  26 . For the arrangement shown there are 2 shelves and 7 bins, 4 bins on the top shelf and 3 the bottom shelf. It is to be understood, however, that depending upon the number of supply containers of liquid beverage components to be stored, the cabinet  20  can be appropriately sized to accommodate more or fewer shelves and more or fewer bins that are carried on the shelves. Opposite sides of each shelf  26  are slidably carried on rails  28  mounted on opposite side walls of the cabinet  20  to accommodate sliding movement of the shelves and bins carried by the shelves out of and into the cabinet. A door  30  is hinged to the cabinet and movable between positions opening and closing the cabinet. 
     As will be described, the supply containers  22  of liquid beverage components or ingredients that are stored in the cabinet  20  are fluid coupled to beverage valves of a beverage dispenser (neither shown) for being dispensed into a cup for service of a drink to a customer. The beverage dispenser may be of a type as described in aforementioned U.S. Pat. No. 6,935,532, the teachings of which have been incorporated herein by reference. When such a beverage dispenser is used, it may be mounted directly atop the cabinet  20  or it may be countertop mounted with the cabinet then being located either below the countertop and dispenser or at a remote location. Alternatively, the cabinet may be an integral lower part of a beverage dispensing apparatus and can have rollers  32  to facilitate its movement. 
     The supply containers or bags  22  of liquid beverage components can comprise beverage concentrates or syrups, in which case a diluent that may be plain or carbonated water can be delivered to the beverage dispensing valves along with the beverage components. To ensure that a quality beverage is dispensed for service to a customer, means (not shown) are provided for chilling the beverage components and any diluent delivered to the beverage valves. Such means can comprise a refrigeration system for chilling the interior of the cabinet  20  within which the supplies of beverage components are stored, and in the case of a beverage dispenser that also dispenses ice, the refrigeration system can also service an icemaker for the dispenser. Alternatively or in addition to chilling the cabinet interior with a refrigeration system, the chilling means can comprise a cold plate through which the beverage components are flowed prior to being delivered to the beverage valves. The supplies of beverage components in the cabinet  20  are coupled to the beverage dispensing valves through fluid lines, and means (not shown) may advantageously be provided to chill the fluid lines along the path of their extension between the cabinet and dispensing valves. 
     The beverage component supply containers  22  are contemplated to be flexible bags of liquid beverage components, each provided with an appropriate valve, such as an LMS (Liquid Molding System) valve, indicated generally at  34 , which is a valve utilizing a silicon member in which there is a “+” shaped cut that normally is closed but through which a fluid connector can be moved to establish fluid communication with the liquid beverage component in the bag interior. One such LMS valve  34  is shown in FIGS.  3  and  5 - 10 , and with particular reference to  FIG. 5 , the valve comprises a generally cylindrical body member  36  having a fluid passage  38  extending axially therethrough. The body member  36  has a pair of axially spaced circumferential recesses  40  and  42 , the purpose of which recess  40  will later be described, and the body member is sealed at one end to and about an opening in the flexible bag  22 , such that an inner end of the axial passage  38  communicates with the bag interior. The silicon member in which there is the “+” shaped cut is in and normally closes the passage  38 , so that liquid beverage component in the bag does not unintentionally flow out of the bag through the passage. 
     The liquid beverage component in each bag  22  is accessed via an associated elbow connector, indicated generally at  44 . The elbow connector has a tubular inlet extension  46  that may be manually moved into the passage  38  of the LMS valve  34  and through the “+” shaped cut in the silicon member in the passage to place an inlet to a passage  48 , extending through the tubular inlet extension, into fluid communication with liquid beverage component in the bag. From the tubular inlet extension  46  the passage  48  extends through a barb fitting  50  of the elbow connector to an outlet from the passage at an end of the barb fitting, whereby liquid beverage component in the bag may be flowed out of the bag through the passage  48  in the elbow connector  44 . The barb fitting attaches to an appropriate flexible tubing  52  ( FIG. 3 ) that provides a fluid flow path for the liquid beverage component through a pump (not shown) to a beverage valve of the beverage dispenser (neither shown), such that operation of the pump draws liquid beverage component from the bag  22  and through the LMS valve, elbow connector and flexible fluid line to the beverage valve. When the bag  22  is emptied of liquid beverage component, the tubular extension  46  of the elbow connector  44  can be withdrawn and released from the passage  38  in the LMS valve  34 , whereupon the “+” shaped cut in the silicon member in the passage closes to prevent leakage from the bag through the LMS valve. A handle  54  on the elbow connector  44  facilitates manual manipulation of the elbow connector in its connection and disconnection with and from the LMS valve  34 . 
     The arrangement by which the supply bags  22  of beverage components are carried in the bins  24 , by which the bins are supported on the sliding shelves  26  in the cabinet  20 , and by which the elbow connectors  44  are fluid coupled to the LMS valves of the bags for flow of liquid beverage components to beverage dispensing valves, facilitates convenient loading and replacement of depleted beverage component supply bags in the cabinet. In particular, to load bags of liquid beverage components into the cabinet  20 , a shelf  26  of the cabinet is slid forward out of the cabinet, such as is seen in  FIG. 2 . One or more of the bins  24  carried by the shelf may then be lifted off of the shelf, with an slot  56  in a front wall of the bins providing a means by which an operator can easily grip the bins to lift them off of the shelf, or the bins can be left in place on the shelf. With the bins either in place on or removed from the shelf, a liquid beverage component bag, such as the bag  22  which is shown upside down in  FIG. 6  to illustrate the location of its LMS valve  34 , is placed in each bin in an orientation such that its LMS valve faces downward and is toward a front wall of the bin. Each bin is provided with a pear-shaped passage or opening  58  in its bottom wall toward its front wall, which pear-shaped opening has an enlarged portion away from the bin front wall that is large enough to accommodate extension therethrough of the cylindrical body member  36  of the LMS valve of a bag  22  and a smaller portion toward the bin front wall that has a width slightly smaller than the outside diameter of the of the cylindrical body member. When a bag is placed into a bin, the cylindrical body member of the LSM valve is first extended downward through the enlarged portion of the pear-shaped opening  58  in the bin bottom wall. The cylindrical body member of the valve is then manually moved forward into the smaller forward portion of the pear-shaped opening, so that peripheral edges of the bin bottom wall that define the smaller portion of the pear-shaped opening  58  move into the circumferential recess  40  in the cylindrical body member  36  of the LMS valve, thereby to secure the LMS valve against vertical movement relative to the bin. 
     After the bins  24  are loaded with bags  22  full of liquid beverage components, they are placed back onto the cabinet shelf  26  if previously removed therefrom, or are otherwise left in place on the shelf. In either case, laterally spaced openings  60  in a front edge of the shelf accommodate downward extension therethrough of the LMS valves  34  of the bags of beverage components that have been placed in the bins. The tubular inlet extensions  46  of the elbow connectors  44  associated with the LMS valves  34  of the bags  22  are then moved into the axial passages  38  of the valves to fluid couple the contents of the bags through fluid lines  52  to dispense valves of a beverage dispenser. During fluid coupling of each elbow connector to its LMS valve, receipt of the edges of the bin bottom wall within the valve recess  40  secures the valve against upward movement as the elbow connector is extended into it, thereby facilitating establishment of the fluid connection. The cabinet shelf is then slid backward into the cabinet  20  and the cabinet door  30  is closed. 
     Upon depletion of a bag  22  of liquid beverage component, as may be detected in any suitable manner well understood by those of skill in the art, the door  30  of the cabinet is opened and the shelf  26  supporting the bin  24  in which the depleted bag is carried is slid forward out of the cabinet. The elbow connector  44  fluid coupled to the LMS valve  34  of the depleted bag is then uncoupled from the LMS valve, whereupon the LMS valve is manually slid rearward into the enlarged rearward portion of the pear-shaped opening  58  so that it is released for vertical movement out the opening, at which point the depleted bag can then be lifted out of the bin and replaced with a fresh bag of liquid beverage component in the manner above described. 
     The invention therefore provides an improved liquid beverage component handling and storage system for a beverage dispenser, which accommodates convenient storage of bags of liquid beverage components for delivery to dispense valves of a beverage dispensing machine. The arrangement also accommodates convenient replacement of depleted bags of beverage components. While the valve carried by each bag of liquid beverage component has been described as an LMS valve, it is understood that any other suitable type of valve and connector for fluid coupling with the valve may be used in practice of the invention. 
     While embodiments of the invention have been described in detail, various modifications and other embodiments thereof may be devised by one skilled in the art without departing from the spirit and scope of the invention, as defined in the appended claims.
A product storage and handling system for a beverage dispenser is characterized by a cabinet in which a plurality of bins are removably supported on one or more shelves that may be slid into and out of the cabinet. Each bin is for containing a removable container of liquid beverage component, a fluid valve of which container extends downward through and is releasably secured against vertical movement in a lower opening in the bin. A connector coupled to a fluid line leading to a beverage valve of a beverage dispenser is arranged to be conveniently fluid coupled with and decoupled from the fluid valve of the bag. When a shelf of slid out of the cabinet, the bins supported by it may, if desired, be lifted off of and replaced on the shelf for during replacement of a depleted bag of liquid beverage component. Alternatively, the bins may remain supported on the shelf during replacement of a depleted bag of liquid beverage component.
