Abstract

An improved holder for pivotally supporting a flexible bag containing a liquid component is disclosed for use in a multiple fluid dispensing system. The holder supports the bag in an upright position for space efficiency as well as for dispensing efficiency. An improved shelving system for pivotally supporting a plurality of holders in a compact row and in an upright dispensing position is also disclosed. An improved dispensing system incorporating the disclosed shelving system and flexible bag holder is also disclosed.

Claims

1. A shelving system for pivotally supporting flexible bags containing fluid components and having ports for connecting to one of a plurality of pumps, the shelving system comprising:

a bottom plate connected at least two spaced-apart upwardly extending rear tabs, interface, by which a user can cause the control mechanism to switch between the first setting and the second setting

the bottom plate comprising a plurality of space-apart openings, each opening for providing access to an inlet of a pump,

a plurality of holders pivotally mounted on the cross beam, each holder comprising

a rear wall disposed between and connected to two side walls,

a bottom wall disposed between and connected to the side walls,

the bottom wall and side walls defining a u-shaped slot for receiving the cross beam through the bottom wall and into distal ends of the u-shaped slot disposed in the side walls so that the holder can pivot about an axis defined by the cross beam,

the bottom wall also comprising a cut-out for accommodating the port of the flexible bag,

the holder being able to pivot between a connected position where the cut-out of bottom wall is in alignment with one openings in the bottom plate and the bottom wall is at least substantially horizontal and substantially parallel to the bottom plate so that the port of the bag can engage the inlet of a pump and a disconnected position where the bottom wall is pivoted away from the bottom plate.

2. The shelving system of claim 1 wherein the a bottom surface of the bottom plate is connected to a plurality of spaced-apart brackets for supporting the pumps below the bottom plate with inlets of the pumps extending up through the spaced-apart openings in the bottom plate.

3. The shelving system of claim 1 wherein the at least two tabs comprises a plurality of spaced-apart rear tabs connected to the cross beam with openings between adjacent tabs for accommodating the holders and for permitting limited rearward pivotal movement of the holders.

4. The shelving system of claim 1 wherein each bag is disposed within a box that is received in and supported by its respective holder.

5. The shelving system of claim 1 wherein each holder has an open front for receiving the flexible bag.

6. The shelving system of claim 1 wherein each holder has an open top for receiving the flexible bag.

7. The shelving system of claim 1 wherein each holder has an open top and an open front for receiving the flexible bag.

8. A multiple fluid dispensing system comprising:

a plurality of flexible bags each bag containing a fluid and having a port for connecting to one of a plurality of pumps, each of the pumps having an inlet nozzle for insertion into a port of one of the bags, the bags and pumps being supported by at least one shelving system comprising

a bottom plate connected at least two spaced-apart upwardly extending rear tabs,

the rear tabs being connected to a horizontal cross beam,

the bottom plate comprising a plurality of spaced-apart openings, each opening for providing access to an inlet nozzle of one the pumps,

a plurality of holders, each holder for holding one of the bags and being pivotally mounted on the cross beam and in alignment with one of the openings in the bottom plate, each holder comprising

a rear wall disposed between and connected to two side walls,

a bottom wall disposed between and connected to the side walls,

the bottom wall and side walls defining a u-shaped slot for receiving the cross beam through the bottom wall and into distal ends of the u-shaped slot disposed in the side walls so that the holder can pivot about an axis defined by the cross beam,

the bottom wall also comprising a cut-out for accommodating the port of the flexible bag,

the holders being able to pivot between a connected position where the cut-out of bottom wall is in alignment with one openings in the bottom plate and the port of the bag in the holder engages the inlet of the pump that extends up through the opening in the bottom plate and a disconnected position where the bottom wall at the holder is pivoted away from the bottom plate and the port of the bag is disconnected from the inlet of the pump.

9. The dispensing system of claim 8 wherein the a bottom surface of the bottom plate is connected to a plurality of spaced apait brackets for supporting the pumps below the bottom plate with inlets of the pumps extending up through the spaced-apart openings in the bottom plate.

10. The dispensing system of claim 8 wherein the at least two tabs comprises a plurality of spaced apart rear tabs with openings between adjacent tabs for accommodating the holders and for permitting limited rearward pivotal movement of the holders.

11. The dispensing system of claim 8 wherein each bag is disposed within a box that is received in and supported by the holders.

12. The dispensing system of claim 8 wherein each holder has an open front for receiving the flexible bag.

13. The dispensing system of claim 8 wherein each holder has an open top for receiving the flexible bag.

14. The dispensing system of claim 8 wherein each holder has an open top and an open front for receiving the flexible bag.

15. The dispensing system of claim 8 wherein the port of each bag comprises a rigid conduit disposed between and connected to three spaced-apart and parallel flanges including an inner flange, a middle flange and an outer flange, the middle and outer flanges being sandwiched between the bottom wall of the holder and the bottom plate when the holder and bag are in a dispense position, and portions of the bottom wall of the holder being sandwiched between the inner and middle flanges when the bag is inserted into the holder.
