Title: Bag-in-box dispensing spout capture mechanism

Description:
FIELD OF THE INVENTION 
     This invention relates generally to beverage dispensing, in particular to a capture mechanism for a dispensing spout of a bag-in-box dispensing system. 
     BACKGROUND TO THE INVENTION 
     In the field of beverage and liquid systems an apparatus, commonly known as a bag-in-box package, is used to store and dispense beverages such as soft drinks, fruit juices, water, or alcohol, but not limited thereto. Typically such bag-in-box packages comprise a collapsible bag or bladder disposed within a cardboard or plastic box. The bag is typically provided with a dispensing spout which protrudes through a side wall of the box for dispensing liquid stored within the bag. 
     One of the problems associated with early prior art bag-in-box packaging is that the tap or spout needs to be supported within one of the side walls of the box and this results in an accumulation of the liquid in the area of the box below the level of the tap or spout. Thus the residual portion of liquid remaining in the bag is wasted. It is cumbersome and awkward for a user to open the nearly empty box, remove the bag and to squeeze the remaining fluid out from the box. This problem is amplified when a bag and box container is located within a dispensing unit wherein access to the bag is restricted. 
     A number of attempts have been made to solve the above mentioned problems. European Patent No. EP 1 520 836, in the name of Model AG, discloses a bag-in-box dispensing apparatus in which the box is tilted at an angle to the dispensing apparatus to urge the liquid from the bag and box through a tap or spout. Another solution is proposed by US Patent Publication Number US 2003/0155372, which discloses a bag-in-box apparatus where the interior base of the box is sloped or terraced downwards towards the spout of the bag such that gravity helps the liquid towards the spout, as shown in  FIG. 1  by the dotted lines. However this solution has been shown to be unsatisfactory as it still results in waste liquid forming at the base of the box. 
     The inventors of the present invention have overcome these problems with an improved bag-in-box system for dispensing liquids, as described in International Patent Application No. PCT/EP2008/065180. In the cited application, an extended section of the box is removable to permit the dispensing spout project through the box to a position lower than previously possible (substantially under the level of the base of said container) so that the liquid is fully dispensed without the need for additional manual force. This solution eliminates the requirement to manually squeeze the remaining liquid from the bag and is thus far more efficient. 
     A second improvement is to specifically introduce extra air into the bag which improves the dispensing rate of the fluid at lower volumes. 
     Although the bag-in-box system of PCT/EP2008/065180 is a significant improvement on the traditional bag-in-box systems, there is an underlying problem in that the spout may not remain in its lower dispensing position without external assistance. The applicants of the present invention have described in PCT/EP2008/065180 a capture mechanism to overcome this. However, the described capture mechanism is inconvenient to use. As one tries to manoeuvre the tap into the tap capture mechanism, the pressure of the water pressing out and against the tap makes the action of trying to manoeuvre the tap into the tap capture mechanism very cumbersome. The user has to contend with manoeuvring the tap into place whilst at the same time holding back a bulging bag of fluid. 
     The capture mechanism of the present invention overcomes some or all of the above-mentioned problems. 
     OBJECT OF THE INVENTION 
     The object of the present invention is to provide a capture mechanism for securely holding a dispensing spout of a flexible bag housed in a box in place in an external dispensing position beneath the base level of the box. It is a further object of the present invention to provide a unit for use in dispensing a liquid from a box housing a flexible bag containing liquid to be dispensed comprising a capture mechanism of the present invention and a box-supporting shelf adapted to accommodate the capture mechanism. It is a still further object of the present invention to provide a means to increase the speed of chill transfer to the fluid in the bag housed in the box. It is also an object of the present invention to provide a capture mechanism that facilitates the insertion of the box into a dispensing unit. It is a further object of the invention to provide a capture mechanism which easily interfaces with a dispensing unit. 
     SUMMARY OF THE INVENTION 
     According to one aspect of the present invention, there is provided a capture mechanism for a dispensing spout of a bag-in-box liquid dispenser, the dispenser adapted to enable said dispensing spout protrude through at least the base of its box, the capture mechanism comprising: 
     means for capturing a dispensing spout of a bag-in-box liquid dispenser, 
     
         
         
           
             wherein in use with at least a portion of the capture mechanism cooperating with the box of a bag-in-box liquid dispenser adapted to enable its dispensing spout protrude through at least the base of its box, the capturing means is positioned to maintain the dispensing spout in a low dispensing position relative to the level of the base of the box. 
           
         
       
    
     The capture mechanism may further comprise a shelf for supporting at least a portion of the base of the box. The shelf may lie in a plane higher than that of the means for capturing so as to ensure the base of the box is held above the spout when captured. The shelf may therefore act as stop means to maintain the base of the box in a relatively high position. 
     The capture mechanism may further comprise means for abutting at least a portion of the front face of a box of a bag-in-box dispensor. The means for abutting may be substantially perpendicular to the shelf so as to form a roughly L-shaped corner into which the corner of the box may be accommodated. The shelf may be at an inclined angle to the base of the capture mechanism to as to angle the base of a box supported thereon, and tip it forward slightly. The capture mechanism may further comprise a well for accommodating a portion of the bag of a bag-in-box dispenser. The capture mechanism may comprise a block portion to securely accommodate the dispensing spout of a bag-in-box liquid dispenser. The block portion may comprise a coupling member for releasably engaging with a spout-receiving portion. The coupling member may be fully detachable from the spout-receiving portion. In addition/in contrast, the coupling member may be tethered to the spout-receiving portion. The coupling member and a co-operating section of the spout-receiving portion may comprise complementary male and female formations. At least one of said coupling member and said spout-receiving portion preferably comprises locking means. The locking means may be pivotally connected to either side of the coupling member and receivable into complimentary recesses in the spout receiving portion. The locking means may be released by squeezing their upper ends towards each other to release catches on the lower ends of each locking arm from corresponding catches within the complimentary recesses. Both the coupling member and the spout-receiving portion may be provided with a substantially U-shaped channel to engage about the gland of a spout to be captured. 
     According to a further aspect of the present invention there is provided a capture mechanism for a dispensing spout of a bag-in-box liquid dispenser, the dispenser adapted to enable said dispensing spout protrude through at least the base of the box, the capture mechanism comprising:
         a platform adapted to co-operate with the base of a box of a bag-in-box liquid dispenser; and   means for capturing a dispensing spout of a bag-in-box liquid dispenser, wherein in use with the platform mating with the box of a bag-in-box liquid dispenser adapted to enable its dispensing spout protrude through at least the base of its box, the capturing means lies in a plane beneath the platform to maintain the dispensing spout in a low dispensing position relative to the level of the base of the box.       

     One of the main advantages of the present invention is that the spout is kept in a low dispensing position, thereby negating the need to apply further manual force to the bag in the box to ensure that all the liquid has been dispensed therefrom. 
     Preferably, the spout is adapted to be dropped down to a low dispensing position such that the spout is positioned at a level under the base of the container in use. This provides a gravitational well to urge the liquid from the bag to be dispensed via said spout. It will be appreciated that the liquid flow rate is maximised through the funnelling of the liquid in the bag into a lower level “gravitational well”, before dispensing from the lowest level of the spout. As the box once opened is inverted and the gravitational pressure of the liquid is directed downwards into the box and not outwards through the now open box. This then allows the extra material of the bag (portion of the bag attached to the spout) to be easily manoeuvred into place into the tap capture mechanism without having to contend with the pressure exerted by the liquid contained within the bag. 
     The capturing means may comprise a block to securely accommodate the dispensing spout of a bag-in-box liquid dispenser. The block may further comprise a locking means to releasably lock the capturing means to the platform. Preferably, the block comprises a coupling member for releasably engaging with a spout-receiving portion of the block. It is of course understood that the locking means of the coupling member and the co-operating section of the spout-receiving portion can comprise any locking means known to those skilled in the art other than male and female formations, for example, complementary threaded counterparts, fasteners, magnets, clips, and the like commonly used in the art. 
     In one embodiment, the coupling member is pivotally attached to the spout-receiving portion. In a further embodiment, the coupling member is fully detachable from the spout-receiving portion. In this format, it is simply a locking “block” which allows a tap to be captured easily when the liquid in the bag of a bag-in-box system is not pressing against the box opening. For each of the above embodiments, the coupling member and a co-operating section of the spout-receiving portion comprise complementary male and female formations. 
     In a further embodiment of the present invention, the block comprises a single unit having an open-sided internal channel configured to securely accommodate the dispensing spout. The block further comprises opposing jaws spaced-apart so as to provide an opening into the internal channel. 
     According to one embodiment of the invention, at least a portion of the platform is adapted to be received into an aperture in the base of a box of a bag-in-box dispenser. In an alternative embodiment, the platform may form part of a shelf for supporting a box on which a box sits. 
     It will also be appreciated that the platform may take different forms and shapes, and the level of cooperation between the base of the box and the platform may vary from only supporting the base or part of the base of the box to a more engaging contact wherein there becomes some level of inter-engagement between the two. 
     According to one embodiment of the invention, the platform is an integral part of the main body of the capture mechanism and take the form of shelf, which may be located behind the means for capturing on the box-facing side of the capture mechanism. 
     It is desirable that the platform comprises:
         an elongated section extending distal of the capturing means to co-operate with the base of the box;
           (i) a stepped ledge at a proximal end of the elongated section to clip onto the base of the box; and   (ii) a flange at a distal end of the elongated section receivable into an aperture in the base of the box, the stepped ledge and flange adapted to operate in tandem to secure the platform to the base of the box.   
               

     A capture mechanism of the present invention may further comprise a recess in the platform or elsewhere to accommodate a portion of the bag attached to the dispensing spout protruding through at least the base of the box. The advantage of this recess is that it can accommodate a portion of the bag protruding through at least the base of the box, thereby assisting in maintaining the spout in a low dispensing position when engaged with the capture mechanism of the present invention. Further, the recess prevents the fluid-filled bag from bulging out of the bottom or front of the box (after the tear off portions of the box have been removed) when a user is trying to insert the box into a liquid dispenser. 
     In a further aspect of the present invention, the flange is adapted to be received into an aperture in the base of the box. The flange comprises a raised lip at a distal end of the elongated section. 
     In aspects of the present invention, it is desirable that each block or coupling member and spout-receiving portion comprise a substantially U-shaped channel. It will be appreciated however that the respective channels may take alternate forms to suit various shaped spouts/taps. 
     The present invention further provides a capture mechanism for a dispensing spout of a bag-in-box liquid dispenser, the dispenser adapted to enable said dispensing spout protrude through at least the base of its box, the capture mechanism comprising:
         a shelf adapted to support at least a portion of the base of a box of a bag-in-box liquid dispenser; and   means for capturing a dispensing spout of a bag-in-box liquid dispenser, wherein in use with the shelf supporting at least a portion of the box of a bag-in-box liquid dispenser adapted to enable its dispensing spout protrude through at least the base of its box, the capturing means lies in a plane beneath the shelf to maintain the dispensing spout in a low dispensing position relative to the level of the base of the box.       

     The capture mechanism may further comprise a stop means or abutments to engage the front face of the box. The capture mechanism may further comprise a well or cavity to accommodate a portion of the bag projecting from the opening of the box in use. Two or more parts of the capture mechanism may be tethered together using a flexible tether or security cord, wire or strap. A flexible tether may be used to prevent any of the cooperating parts from becoming lost or misappropriated. The flexible nature of the tether allows for full 360 degree movement of any tethered parts. 
     In a further aspect of the present invention, there is provided a unit for use in dispensing a liquid from a bag-in-box liquid dispenser, the dispenser adapted to enable a dispensing spout protrude through at least the base of the box, the unit comprising:
         a capture mechanism according to present invention and as described above, and   a box-supporting shelf adapted to accommodate the capture mechanism. It is preferable that the supporting shelf comprises:
 
an upper surface for supporting the base of a box, the upper surface having defined therein a cavity into which the capturing means of the capture mechanism is accommodatable. The supporting shelf may further comprise engagement means within the cavity to co-operate with at least one corresponding tab provided on said capturing means to releasably lock the capture mechanism to the supporting shelf.
       

     Preferably, the releasable engagement means is selected from the group comprising a magnet, a clip, and complimentary engagement formations. It will be readily understood by those skilled in the art that any other engagement means may be used that are described in the common general knowledge and known in the art. 
     The supporting shelf may further comprise an actuator for releasing the capture mechanism from the releasable engagement means of the supporting shelf. This provides a convenient means for disengaging the capture mechanism from the unit in the event that all the liquid has been dispensed from the bag-in-box system and requires replacement. 
     The supporting shelf may further comprise a heat transfer contact plate to engage with a bag in a bag-in-box dispenser. The contact plate helps drive chilling into the exposed bag by virtue of the bag being in contact with the plate. 
     It should also be understood that platform may form an integral part of the supporting shelf. The platform may also co-operate with the heat transfer contact plate to further extend the contact plate by association with the platform into the actual box on the inner side, thus extending the surface chilling area. This arrangement greatly speeds up the liquid chilling process. 
     The advantages of the above-described unit is that the unit supports the body of the box after the tear off sections have been removed so as to prevent or minimise any bulging of the liquid in the bag out of the now exposed hole or holes in the box. 
     A further advantage of the present invention is that the unit allows capture of a tap when fluid is not pressing against the tap and then subsequent placement of the now captured tap into a separate dispensing unit without having to make further movements to engage the tap with the tap capture mechanism. The only engagement is by the capturing means (and not the tap itself) with the dispensing mechanism. The box—now attached to the tap capture mechanism—can easily be then inserted into a cooling shelf of the dispenser, with the tap capture mechanism now acting as a centring and locking mechanism to ensure that the box is properly aligned on the cooling surfaces of the heat transfer contact plate and that the tap capture mechanism (and hence the bag and box and tap) is easily centred into the correct dispensing position, with minimal further input from the user. 
     A further advantage of the present invention described above is that when in use, the tap capture mechanism extends into the box, contacts the heat transfer contact plate, and at the same time is in direct contact with the bag (the protective cardboard outer having been removed), thereby speeding up the heat transfer to chill the liquid in the bag and preventing the bag from bulging out of the box once the tear-off sections of the box have been removed.

     DETAILED DESCRIPTION OF THE DRAWINGS 
     It should be readily apparent to one of ordinary skill in the art that the embodiments disclosed herein below represent generalised embodiments only, and that other arrangements are possible and are embraced by the present invention. 
     In  FIG. 1  there is illustrated a side view in cross section of a mechanism according to the present invention. The mechanism is for use with bag-in-box dispensing systems, which generally comprise a box having formed therein an opening near its base to allow a dispensing spout project from the box, and in some instances allow a portion of the bag to be substantially pulled through the opening provided therein, so that the spout projects substantially under the level of the base of said box in a low dispensing position. The mechanism is generally indicated by the reference numeral  1 . The capture mechanism comprises a platform  2  and a capturing means  3 . The platform  2  is adapted to engage with and support the base of the box, while the capturing means  3  releasably engages with the platform  2  to capture the spout  11  (see  FIG. 2 ). 
     The capturing means  3  comprises a block  60  having a coupling member  62  and a spout-receiving portion  4 , which is adapted to co-operate with the coupling member  62 . The platform  2  comprises an elongated section  5  extending distal of the capturing means  3  and a flange  6  at the distal end of the elongated section  5 . The spout-receiving portion  4  co-operates with the coupling member  62  by a co-operating section  12 . 
     The platform  2  further comprises a recess  7  to accommodate the portion of the bag pulled out of the box in the spout&#39;s dispensing position. 
     The coupling member  62  further comprises a locking means  9 . The coupling member  62  and spout-receiving portion  4  each comprise a substantially U-shaped channel  17 , 18  to engage with and accommodate a gland  21  in fluid communication with the spout  11  (see  FIG. 2 ). Both the coupling member  62  and spout-receiving portion  4  comprise complementary male and female formations  14 , 15 . In the current embodiment as illustrated in  FIG. 1 , the male formation  14  is shown on the coupling member  62 , while the female formation  15  is shown on the spout-receiving portion  4 . It should be understood by the skilled artisan that the placement of the male and female formations  14 , 15  on the coupling member  62  and spout-receiving portion  4  may be reversed. It should also be understood by the skilled artisan that the male and female formations  14 , 15  could take alternate forms in terms of shape and size. 
     As shown in the embodiment as illustrated in  FIG. 1 , the coupling member  62  is pivotally attached to the spout-receiving portion  4  by hinge  16 . The coupling member  62  pivots about the hinge  16  in the direction of arrow A to engage with the co-operating section  12  of the spout-receiving section  4 . The male and female formations  14 , 15  releasably engage with each other and the substantially U-shaped channels  17 , 18  accommodate and secure the gland  21  in fluid communication with the spout  11  of a bag-in-box system in the dispensing system (explained in more detail below, see  FIGS. 5 and 6 ). 
     As illustrated in  FIG. 2 , there is shown an alternative embodiment of the present invention where the coupling member  62  is fully detachable from the capturing means  3 . In use, the coupling member  62  is placed against a front face of a box  19  of a bag-in-box system, with the spout  11  in a low dispensing position through an aperture  50 . The coupling member  62  is moved in the direction of arrow B to releasably engage with the co-operating portion  12  of the capturing means  3 . When the coupling member  62  and spout-receiving portion  4  have engaged, the gland  21  of the spout  11  is secured within the substantially U-shaped channels  17 , 18 , ensuring that the spout  11  is secured in a low dispensing position. 
     In an alternative embodiment, a universal gland capturing saddle (not shown) may be reversibly secured either around the gland  21  or within the substantially U-shaped channels  17 , 18 . The universal gland capturing saddle can adapt to the shape and/or size of any gland used in bag-in-box systems, such as gland  21  as shown in  FIG. 2 . In a further alternative embodiment of the present invention, the block  60  comprises a single unit having an open-sided internal channel configured to securely accommodate the dispensing spout. The block comprises opposing jaws spaced apart so as to provide an opening into the internal channel. It is advantageous to have the jaws biased closely together at rest but moveable apart to increase the opening into the internal channel. The opening provides a means by which the block  60  can be pushed over the gland  21 , to force the gland  21  into the internal channel, wherein it is securely engaged. When the block  60  is pushed over the gland  21  and the gland secured within the internal channel, the jaws return to their original biased closed/nearly closed position trapping the gland within the block. 
       FIG. 3  shows the underside of the arrangement shown in  FIG. 2 , wherein it can be seen that the box  19 , for which this embodiment of capture mechanism is designed for use with, is provided with a second aperture  22  in its base  26 . The primary purpose of this second aperture  22  is to gain access to the bag inside the box  19 . Access to the internal bag is desirable to enable a heat transfer contact plate to be brought into direct contact with the bag to cool the liquid contained therein. In prior art arrangements, the box may be placed directly on a cooling shelf or plate however this is undesirable as the weight of the liquid in the bag can force the bag to bulge out through the aperture in the base of the box. This problem is overcome by the elongate section  5  of the platform  2  of the capture mechanism shown in  FIGS. 1 to 3 . As shown in  FIG. 7 , the elongated section  5  of the platform  2  is adapted to cover the box&#39;s base aperture  22  to prevent the bag from protruding out through the aperture. Cooling of the bag is then affected via the platform  2 . The weight of the liquid in the bag will maintain direct and close contact between the bag and the upper face of the section of the platform  2  covering aperture  22 . The underside of this section of the platform  2  can then be brought into direct contact with a heat transfer contact plate or shelf. 
     A flange  6  is provided at the distal end of the elongated section  5  to maintain and secure the platform  2  against the base of the box against the gravitational pressure of the fluid-filled bag. In use, flange  6  is tucked inside aperture  22  as shown by arrow D in  FIG. 3 . Flange  6  comprises a raised lip portion  13  that is adapted to engage with the interior back wall  40  of the box. 
     The platform  2  further comprises a stepped ledge  52  configured to engage with aperture  50  provided to allow a portion  25  of a bag  24  to be pulled through the opening of the box  19  prior to engaging the mechanism  1  with the bag-in-box system, as illustrated in  FIGS. 4 and 5 . In use, when the platform  2  is received in the apertures  50 , 22  of the box  19 , the stepped ledge  52  rests on an edge  53  of the aperture  50  inside the base  26  to secure the platform  2  inside the box  19 . 
       FIG. 3  also illustrates by way of example the steps by which the capture mechanism  1  of the present invention may engage with a bag-in-box system. For instance, the first step is where, when the box  19  is positioned so that the base  26  of the box  19  is facing upwards to a user, the platform  2  of the mechanism  1  engages with the apertures  22 , 50  in the base  26  of the box  19 . The platform  2  engages with the base  26  of the box  19  via raised lip  13  of flange  6 . The raised lip  13  is inserted into the base  26  via aperture  22  in the direction of arrow D. The raised lip  13  slips through the aperture  22  and rests on an edge  23  of the aperture  22  inside the base  26  and abuts against the back wall  40  of box  19 . The stepped ledge  52  rests on the edge  53  of the aperture  50  (see  FIGS. 4 and 5 ). A portion of the elongated section  5  of the platform  2  and the box engaging means  6  are in contact with the bag  24  accommodated within the box  19 . The contact between the bag  24 , elongated section  5 , and engaging means  6  prevent the bag  24  from bulging and protruding through aperture  22  of box  19 . When the platform  2  is in an engaged position with apertures  22 , 50 , the gland  21  of the spout  11  is accommodated within the substantially U-shaped channel  18  of the spout-receiving portion  4 , and the portion  25  of the bag  24  is accommodated in the recess  7  (not shown—see  FIG. 8 ). The portion  25  is pulled through the opening of the box  19  prior to engaging the mechanism  1  with the bag-in-box system. 
     The second step is to secure the spout  11  in a low dispensing position by positioning the coupling member  62  over the gland  21  of the spout  11  and moving the coupling member  62  in the direction of arrow E. The male and female formations  14 , 15  on the coupling member  62  and co-operating portion  12  engage, thereby locking the coupling member  62  and capturing means  3  together. The spout  11  is now secured in a low dispensing position. 
     In an alternative embodiment, a universal saddle (not shown) can also be used in conjunction with coupling member  62  and spout-receiving portion  4  to secure the spout  11  in a low dispensing position as explained above. The universal saddle is configured to adapt to any shape and/or size of gland  21  used in the prior art bag-in-box systems, as explained above. 
     As illustrated in  FIG. 6 , there is shown a further alternative embodiment of a capture mechanism of the present invention, generally indicated by reference numeral  20 , wherein the coupling member  62  is pivotally attached to the spout-receiving portion  4  by hinge  16 . In this embodiment, the spout-receiving portion  4  is not attached to a platform. As such, the capture mechanism  20  of  FIG. 6  does not engage with the base of the box due to the lack of a platform, but instead engages with the spout  11  of a bag-in-box system. The coupling member  62  pivotally moves in an arc, as indicated by arrow C, to releasably engage with the spout-receiving portion  4 . When in use, the capture mechanism  20  is moved toward the spout  11  in the direction of arrow F when in a disengaged state. The coupling member  62  is pivoted about hinge  16  in the direction of arrow C, engaging with the gland  21  of the spout  11 , and releasably co-operating with co-operating portion  12  of the spout-receiving portion  4 . The male and female formations  14 , 15  of the capture mechanism  20  engage, thereby securing the spout  11  in a low dispensing position. 
     In an alternative embodiment, a universal saddle (not shown) can also be used in conjunction with the capture mechanism  20  to secure the spout  11  in a low dispensing position as explained above. The universal saddle is configured to adapt to any shape and/or size of gland  21  used in the prior art bag-in-box systems, as explained above. In a still further embodiment, the coupling member  3 /spout-receiving portion  4  of  FIGS. 1 to 5  and capture mechanism  20  of  FIG. 6  can each be comprised of a single block (not shown) having a substantially circular open sided internal channel configured to securely accommodate the gland  21  of the spout  11 . The block comprises opposing jaws spaced apart so as to provide an opening into the internal channel. It is advantageous to have the jaws biased closely together at rest but moveable apart to increase the opening into the internal channel. The opening provides a means by which the unit can be pushed over the gland  21 , to force the gland  21  into the internal channel, wherein it is securely engaged. When the block is pushed over the gland  21  and the gland secured within the internal channel, the jaws return to their original biased closed/nearly closed position trapping the gland within the block. 
     In  FIG. 7 , there is illustrated a unit for use in dispensing a liquid from the box  19  containing a liquid to be dispensed, the unit generally indicated by reference numeral  30 . There is shown the mechanism  1  engaged with the gland  21  of the spout  11  and a box-supporting shelf  31  adapted to accommodate the mechanism  1 . The box-supporting shelf  31  comprises an upper surface  32  for supporting the base  26  of the box  19 . The upper surface  32  comprises a cavity  33  into which the capturing means  3  is accommodatable. The upper surface  32  further comprises an engagement means  34  within the cavity  33  which co-operates with at least one corresponding tab  35  provided on the capturing means  3 . The tab  35  and engagement means  34  releasably lock the mechanism  1  to the box-supporting shelf  31 . 
     The engagement means  34  may be selected from the group comprising a magnet, a clip, complimentary engagement formations, and the like known to those skilled in the art to provide a releasable engagement means. 
     The mechanism  1  engaged with a bag-in-box system is positioned into the cavity  33  of the supporting shelf  31  in the direction of arrow G. The tab  35  engages with the engagement means  34 . The mechanism  1  can be released from the engagement means  34  of the supporting shelf  31  by activating an actuator  36  provided on the supporting shelf  31 . 
     In a further embodiment, there is provided a heat transfer contact plate  37  on the upper surface  32  of the supporting shelf  31 . When used with a capture mechanism without a platform  2 , the heat transfer contact plate  37  is positioned to engage with the surface of the bag  24  through box aperture  22  to allow heat transfer to chill the bag  24 , and ultimately the liquid stored in the bag  24 . The contact plate  37  further provides additional support to the bag in the box and further acts to stop the bag bulging out of the box once the tear off sections are removed. 
     Alternatively, when being used with one of the platform-based embodiments of the capture mechanism of the present invention, the heat transfer contact plate  37  contacts the platform  2  engaged with the aperture  22  in the base  26  of the box  19  and the bag  24  accommodated therein. The platform  2  may be comprised of any thermally conductive material known to those skilled in the art, for example aluminium, to facilitate heat transfer from the heat transfer contact plate  37  to the liquid contained in the bag  24 . As such, the liquid contained in the bag  24  is cooled rapidly. 
     When the mechanism  1  is engaged with the unit  30 , there is an opening  38  at a front face  39  of the shelf  31  to allow a user access to the liquid dispensed from the spout  11 . In  FIG. 8  there is illustrated a cross section view of the mechanism  1  engaged with the spout  11  of a bag-in-box system and accommodated in the unit  30 . The positioning of the portion  25  of the bag  24  in recess  7  is clearly illustrated in said Figure. Furthermore, the positioning of the mechanism  1  in the unit  30  is also more clearly illustrated, and how the raised lip  13  engages with the lip  23  in the base  26  of the box  19 . As can be further seen in  FIG. 8 , contact plate  37  contacts the elongated section  5  of the platform  2 , and heat transfer occurs, thereby chilling the liquid in the bag  24 . 
     In  FIGS. 9 to 12  there is illustrated an alternative embodiment of the present invention. The illustrated embodiment is a slim-line version of the capture mechanism described above, and reference numerals used above are also used here to annotate the various features of the mechanism. The illustrated embodiment is suitable for use in automatic dispensing units. The capture mechanism comprises a platform  2  and a capturing means  3 . The platform  2  is adapted to engage with and support the base of the box, while the capturing means  3  releasably engages with the platform  2  to capture the spout  11  (as described for  FIG. 2 ). 
     The capturing means  3  comprises a block  60  having a coupling member  62  and a spout-receiving portion  4 , which is adapted to co-operate with the coupling member  62 . In the current embodiment, the coupling member  62  and spout-receiving portion  4  are slimmer in construction than the capture mechanism described above for  FIGS. 1 to 8 . The platform  2  comprises an elongated section  5  extending distal of the capturing means  3  and a flange  6  at the distal end of the elongated section  5 . The spout-receiving portion  4  co-operates with the coupling member  62  by a co-operating section  12  (not shown). 
     The platform  2  further comprises a recess  7  to accommodate the portion of the bag pulled out of the box in the spout&#39;s dispensing position. 
     The coupling member  62  further comprises a locking means  9  (not shown). Both the coupling member  62  and spout-receiving portion  4  comprise complementary male and female formations (not shown). 
     In the embodiment as illustrated in  FIGS. 9 to 12 , the coupling member  62  is pivotally attached to the spout-receiving portion  4  by hinge  16 . As shown in  FIG. 10  the elongated section  5  of the platform  2  is adapted to cover the box&#39;s base aperture  22  to prevent the bag from protruding out through the aperture. Cooling of the bag is then affected via the platform  2 . The weight of the liquid in the bag will maintain direct and close contact between the bag and the upper face of the section of the platform  2  covering aperture  22 . The underside of this section of the platform  2  can then be brought into direct contact with a heat transfer contact plate or shelf. 
     A flange  6  is provided at the distal end of the elongated section  5  to maintain and secure the platform  2  against the base of the box against the gravitational pressure of the fluid-filled bag. In use, flange  6  is tucked inside aperture  22 . Flange  6  comprises a raised lip portion  13  that is adapted to engage with the interior back wall  40  of the box. The platform  2  further comprises a stepped ledge  52  configured to engage with aperture  50  provided to allow a portion  25  of a bag  24  to be pulled through the opening of the box  19  prior to engaging the mechanism  1  with the bag-in-box system, as illustrated in  FIGS. 4 and 5 . In use, when the platform  2  is received in the apertures  50 , 22  of the box  19 , the stepped ledge  52  rests on an edge  53  of the aperture  50  inside the base  26  to secure the platform  2  inside the box  19 . 
     In  FIGS. 13 to 16  there is illustrated an exploded perspective view of a mechanism according to a further embodiment of the present invention. The mechanism is for use with the aforementioned bag-in-box dispensing systems. The mechanism is generally indicated by the reference numeral  101 . The capture mechanism comprises a tap capture base  102  and a coupling member  103 . The tap capture base  102  is adapted to engage with and support the base of the box, while the coupling member  103  releasably engages with the base  102  to capture the spout (not shown). 
     The coupling member  103  comprises a block  105  having a substantially U-shaped channel  104  to engage with and accommodate a gland in fluid communication with the spout (not shown). The gland is the portion of the bag to which the bag&#39;s dispensing spout is attached. The coupling member  103  co-operates with the base  102  by a co-operating section  106 . A tether  170  is provided between coupling member  103  and base  102 . The tether  170  is flexible and may be a plastic wire, cable tie or similar and prevents the coupling member being lost or misappropriated. The flexible nature of the tether  170  allows for the full 360 degree movement of the respective parts of the tap capture mechanism (as against just a “hinged” up and down movement) thus making the actual placement and capture of the gland easier in the tap capture mechanism. Such a tether may be provided on any of the aforementioned embodiments of capture mechanism of the present invention between any two or more cooperating or associated parts. 
     The coupling member  103  further comprises a locking means  109 ,  110 . The locking means  109 ,  110  is pivotally connected at sides  111 ,  112  of the coupling member  103 . The co-operating section  106  comprises corresponding formations  113 , 114  which accommodate the locking means  109 , 110 . The formations  113 , 114  may be configured to a snap-fit configuration. Both the coupling member  103  and co-operating section  106  comprise complementary male and female formations  115 , 116 . In the current embodiment as illustrated in  FIG. 13 , the male formation  115  is shown on the coupling member  103 , while the female formation  116  is shown on the co-operating section  106 . It should be understood by the skilled artisan that the placement of the male and female formations  115 , 116  on the coupling member  103  and co-operating section  106  may be reversed. It should also be understood by the skilled artisan that the male and female formations  115 , 116  could take alternate forms in terms of shape and size. The male and female formations  115 , 116  act as guides to ensure that the coupling member  103  and base  102  are in the correct orientation when securing the spout substantially under the level of the base of the box in a low dispensing position. The co-operating portion  106  further comprises a substantially U-shaped channel  18  to engage with and accommodate the bag&#39;s gland. The substantially U-shaped channels  104 , 118  further comprise stepped ridges  119 ,  120  to further accommodate the spout of the bag of the bag-in-box system. 
     In use, the coupling member  103  is placed against a front face of a box of a bag-in-box system, with the spout in a low dispensing position through an aperture in the base of the box. The coupling member  103  is moved in the direction of arrow A to releasably engage with the co-operating portion  106  of the base  102 . When the coupling member  103  and co-operating portion  106  have engaged, the gland of the spout is secured resting within the substantially circular aperture formed by U-shaped channels  104  and  118 . The neck of the spout protruding thought the aperture in the closed capture mechanism is then additionally supported by stepped ridges  119 ,  120  ensuring that the spout  111  is secured and maintained in a low and static dispensing position. 
     In an alternative embodiment, a universal gland capturing saddle (not shown) may be reversibly secured either around the gland or within the substantially U-shaped channels  104 , 118 . The universal gland capturing saddle can adapt to the shape and/or size of any gland used in bag-in-box systems. 
     The base  102  further comprises a pair of stops  122 , 123  and shelves  124 , 125  juxtapositioned the co-operating portion  106 . In use, the stops  122 , 123  and shelves  124 , 125  project inwardly (in a direction towards the box) from the co-operating portion  106 . It will be appreciated that the shelves  124 , 125  function as the platform as they support and hence cooperate with the base of the box in use. The shelves act to support and maintain the base of the box at a height above the dispensing spout when captured between base  102  and coupling member  103 . The stops  122 ,  123  abut the front face of the box, not only to support same, but also to maintain the box a sufficient distance from the spout when captured to ensure ample room for the portion of bag rear of the spout to project freely out of the box. 
       FIG. 14  shows the top view of the coupling member  103 /base  102  combination. The coupling member  103  is shown having a front face  130  and back face  131 . When engaged with the base  102 , the coupling member  103  lies flush against the co-operating portion  106  and remains within the boundary edge of the co-operating portion  106 . The stops  122 , 123  and shelves  124 , 125  are located on side wings of the base  102 , the side wings extending rearwardly (towards the box when in use) from the back face  131  of the central portion of the coupling member  103 . 
       FIGS. 15A and 15B  show the front and side views, respectively, of the base  102 . As shown in  FIG. 15B , shelf  125  and the rear face  122   a  of stop  122  define a ledge to receive the lower front edge of the box. As shown in  FIG. 15A , it is preferable that shelf  125  is inclined relative to the base of base  102 . This results in an acute angle between shelf  125  and face  122   a . Such an incline aids to support the box in a tilted orientation, wherein the base of the box is lower at its leading/front edge than at its rear. This aids to facilitate complete emptying of the liquid being dispensed. 
       FIGS. 16A and 16B  show the front and side views, respectively, of the coupling member  103 . As illustrated in  FIG. 16B , the block  105  comprises a front face  130  and back face  131 . The front face  130  comprises an arched collar or archway  133  which engages with the gland of the bag of a bag-in-box system. The archway  133  is clearly illustrated in  FIG. 16A . The archway  133  comprises the substantially U-shaped channel  104  and stepped ridge  119 . 
     As illustrated in  FIGS. 17 to 19 , there is shown a further alternative embodiment of a capture mechanism of the present invention, generally indicated by reference numeral  150 . In this embodiment, the coupling member  103  is the same as that described for  FIGS. 13 to 16  using the same reference numerals as used therein, and the tap capture base is generally indicated by reference numeral  151 . Although not shown in these figures, parts  103  and  151  may be tethered together by a tether as per the previous embodiment described above. The base  151  comprises co-operating portion  106  as described above, that is, having corresponding formations  113 , 114  which accommodate the locking means  109 , 110  of the coupling member  103 . The formations  113 , 114  may be configured to a snap-fit configuration. Both the coupling member  103  and co-operating section  106  of the base  151  comprise complementary male and female formations  115 , 116 , respectively. In the current embodiment as illustrated in  FIG. 17 , the male formation  115  is shown on the coupling member  103 , while the female formation  116  is shown on the co-operating section  106 . It should be understood by the skilled artisan that the placement of the male and female formations  115 , 116  on the coupling member  103  and co-operating section  106  may be reversed. It should also be understood by the skilled artisan that the male and female formations  115 , 116  could take alternate forms in terms of shape and size. The male and female formations  115 , 116  act as guides to ensure that the coupling member  103  and base  151  are in the correct orientation when securing the spout substantially under the level of the base of the box in a low dispensing position. 
     The base  151  further comprises a substantially U-shaped channel  118  which further comprises stepped ridge  120  as described above. The channel  118  extends out from the base  151  forming a front face  152  similar to the front face  130  of the coupling member  103  described above. This is clearly illustrated in  FIG. 19B  where the front face  152  extends out and away from a sidewall  154 . As such, the co-operating member  106  is recessed back from the front face  152 , the front face  152  jutting out from the co-operating member  106 . The base  152  further comprises sidewalls  154 ,  155  in communication with a stepped ledge  156 , forming abutments  157 , 158 . The abutments  157 , 158  are configured to engage with and support a front face of a box of a bag-in-box system. Ledge/shelf  156  is an extended version of shelves  124  and  125  of  FIGS. 13 to 16  and is configured to support a portion of the base of the box. The stepped ledge  156  extends downwards from the sidewalls  154 , 155  and perpendicular to a horizontal plane B-B to form an abutment  159 . 
     The base  151  is further configured to accommodate and support a portion of a bag pulled out from the box of a bag-in-box system, namely by a support means  160 . The support means  160  comprises a well or cavity  161  formed by the sidewalls  154 , 155 , the stepped ledge  156 , and the co-operating portion  106 . This is clearly seen in  FIG. 18 , a top plan view of the capture mechanism  150 . In  FIG. 18 , the coupling member  103  lies flush with co-operating portion  106 . 
       FIG. 19A  illustrates a front view of the base  151  of the present invention. As can be clearly seen here, the abutment  159  extends downwards from the horizontal plane B-B from a base  162  of the support means  160 . As with the embodiment shown in  FIGS. 13 to 16 , it will be appreciated that the capture mechanism of  FIGS. 17 to 19  has multiple functions. The mechanism not only captures the spout but also ensures that a desired orientation of captured spout relative to the box is maintained. The capture mechanism is used to capture the spout in a low dispensing position, beneath the base of the box, by maintaining the base of the box in a raised position relative to the captured spout position. Ledge  156  and abutments  157 , 158  act together to maintain the height and depth separation between the captured spout and base of box. 
     It will be further appreciated that in either embodiment shown in  FIGS. 13 to 19 , the shelves  124 ,  125  and  156  extend a short distance rear of the capture mechanism, but may be deeper in alternative embodiments to support a greater portion of the base of the box. 
     One difference between the embodiment in  FIGS. 13 to 16  and that in  FIGS. 17 to 19  is that the latter captures the spout in a position well proud of the opening in the box. This may be more suitable for a unit wherein it is desirable for the spout to be manually activated and hence is required to be accessible from the front of the unit. The former embodiment wherein the capture mechanism stands less proud of the box when the spout is captured may be used when the tap is not manually activated to provide a more streamlined arrangement. For the former embodiment, less bag is required to be pulled from the box and hence no well is required to accommodate same. 
     Both embodiments of capture mechanism from  FIGS. 13 to 19  may be used with a shelf of a dispensing unit similar to that shown in  FIG. 7 .
