Description

FIELD OF THE INVENTION

The present invention is directed to an apparatus for storing and dispensing liquid from a liquid retaining bag. In its most preferred form, the present invention is directed to an apparatus that dispenses liquid from a position above the liquid retaining bag, i.e., a bottom loaded dispensing apparatus (e.g., a bottom loaded water cooler).

BACKGROUND OF THE INVENTION

A significant number of existing water dispensers use gravity as the driving force to dispense water from the water dispenser. In this type of water dispenser, the water bottle is positioned above the dispensing location. These dispensers are referred to as “Top-Loading” water dispensers. Top-Loading water dispensers typically include means for receiving a five (5) gallon water bottle at the uppermost portion of the water dispenser. Five (5) gallon water bottles are quite heavy making it difficult for some individuals to mount the water bottle on the uppermost portion of the water cooler. To overcome the problem of mounting the heavy five (5) gallon water bottles on top of Top-Loading water dispensers, water dispensers in which the water bottle is stored in the lower portion of the water dispenser have been proposed. Since these systems cannot rely upon gravity to dispense drinking water, pumps are typically employed to pump the drinking water to the dispensing location located above the water bottle. These types of water dispensers are referred to herein as “Bottom-Loading” water dispensers.

As an alternative to the five (5) gallon water bottles, water coolers have been developed to use water retaining bags. There are several existing methods to puncture the water retaining bags in order to draw water from the water retaining bag. For example, an upstanding spike is located in such a manner that the water retaining bag is lowered onto the spike and the weight of the water retaining bag serves to cause the spike to puncture the water retaining bag. Systems of this type have an inherent disadvantage. Specifically, if a proper seal is not formed between the water retaining bag and the spike, water will leak. Some water coolers have a spike or other conduit that extends from above the water retaining bag. However, these water coolers do not allow for the water retaining bag to be readily removed and replaced with another water retaining bag.

OBJECTS AND SUMMARY OF THE INVENTION

An object of the present invention is to provide a novel and unobvious apparatus for storing and dispensing liquid from a liquid retaining bag.

Another object of a preferred embodiment of the present invention is to provide an apparatus for storing and dispensing liquid from a liquid retaining bag that is configured such that a liquid transport conduit while moving from a first location to an operating location is oriented at an acute angle to a vertical axis to facilitate puncturing of the liquid retaining bag.

Still another object of a preferred embodiment of the present invention is to provide an apparatus for storing and dispensing liquid from a liquid retaining bag that is configured such that a liquid transport conduit punctures the liquid retaining bag adjacent a sidewall of the liquid retaining bag and removed from a center portion of the liquid retaining bag.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

The preferred forms of the invention will now be described with reference to FIGS. 1-7. The appended claims are not limited to the preferred forms and no term and/or phrase used herein is to be given a meaning other than its ordinary meaning unless it is expressly stated otherwise.

FIGS. 1 through 7

Referring to FIGS. 1 to 7, a preferred form of storage and liquid dispensing unit A is illustrated in one of many possible configurations. As illustrated in FIGS. 5 and 6, storage and liquid dispensing unit A stores and dispenses liquid from a liquid retaining bag B. Liquid retaining bag B is preferably formed from a collapsible material such that as liquid is dispensed from liquid retaining bag B, the bag B collapses. Preferably, the liquid retained by bag B is water. However, any suitable liquid may retained by liquid retaining bag B. Storage and liquid dispensing unit A is preferably used with a bottom loaded water cooler. For example, storage and liquid dispensing unit A housing liquid retaining bag B may be used with the bottom loaded water cooler disclosed in U.S. Pat. No. 8,887,955. The entire contents of U.S. Pat. No. 8,887,955 are incorporated herein by reference. By way of example and without limitation, storage and liquid dispensing unit A housing liquid retaining bag B may be positioned where water bottle E is disposed in FIG. 2 of U.S. Pat. No. 8,887,955. A shell of a bottom loaded water cooler may conceal storage and liquid dispensing unit A housing liquid retaining bag B. The shell may include a removable portion that allows one to readily gain access to storage and liquid dispensing unit A and liquid retaining bag B

Storage and liquid dispensing unit A includes a liquid transport assembly C. End 2 of connector 4 of liquid transport assembly C can be connected to the lower end 40 of riser tube 34 of the liquid dispenser disclosed in U.S. Pat. No. 8,887,955. Liquid can be dispensed from bag B in the same manner that liquid is dispensed from bottle E of U.S. Pat. No. 8,887,955.

Liquid transport assembly C further includes a dip tube 6 preferably having a single hollow cavity 8 extending from an upper open end 10 and a lower open end 12. A spike 14 having a hollow internal cavity 16 extends into lower open end 12. Referring to FIG. 7, spike 14 includes one or more openings 15. The openings 15 can be uniformly spaced around the circumference of the tip of spike 14. The number and spacing of openings 15 can be readily varied as desired. Preferably, spike 14 is fixed to dip tube 6 such that liquid cannot pass between the outer cylindrical wall 18 of spike 14 and the internal cylindrical wall 20 of dip tube 6. Any suitable means can be used to fix spike 14 to dip tube 6. It should be noted that spike 14 and dip tube 6 can be formed as a single piece. Further, spike 14 can be configured such that it seats on and surrounds the lower end 12 of dip tube 6. Upper end of dip tube 6 extends into and is sealingly connected to lower end 22 of connector 4.

Storage and liquid dispensing unit A includes a storage container 24 having a base 26, a cylindrical wall 28 and a skirt 30. Skirt 30 surrounds and seats on the uppermost portion of wall 28. Skirt 30 can be fixed to wall 28 such that it cannot be removed from wall 28 by any suitable means including but not limited to glues, adhesives and/or fasteners. Alternatively, skirt 30 can be removably connected to wall 28 by any suitable means including but not limited to a force or friction fit. Further, skirt 30 and wall 28 can be formed as a single piece.

Base 26 is preferably sealingly connected to the lower portion of wall 28. This connection can be formed by any suitable means. Alternatively, base 26 and wall 28 can be formed as a single piece. Base 26 preferably includes a recess 32 for receiving the bottom of bag B.

Referring to FIGS. 1, 2 and 4 to 6, skirt 30 includes a guide and retaining member 34. As seen in FIGS. 4 to 6, guide and retaining member 34 includes a cylindrical and inclined passageway 36. A longitudinal axis passing through the center of passageway 36 forms an acute angle with a vertical plane and or axis passing though the center of base 26 and the center of bag B. Passageway 36 can be sized relative to dip tube 6, such that dip tube 6 can be held in place (see FIG. 5) by guide and retaining member 34 when no force is applied to dip tube 6 and when a force is applied to dip tube 6, dip tube 6 can move through passageway 36 to an operating position shown in FIG. 6. Referring to FIGS. 4 to 6, lower portion 38 of guide and retaining member 34 is spaced from downwardly extending lip 40 of skirt 30 such that upper portion of wall 28 can extend into the spaced formed between downwardly extending lip 40 of skirt 30 and lower portion 38. However, as previously explained skirt 30 including member 34 and wall 28 can be formed as a single piece.

Referring to FIGS. 1 and 2, guide and retaining member 34 occupies a very small portion of the area of the upper opening of storage container 24. This allows the liquid retaining bag B to be readily removed from storage container 24 and replaced with a new and fully filled liquid retaining bag B without removing skirt 30. Further, as seen in FIG. 5, the liquid transport assembly C can be held in a raised position to allow for removal and replacement of the liquid retaining bag B. As seen in FIG. 6, guide and retaining member 34 guide dip tube 6 such that spike 14 punctures bag B adjacent a sidewall 50 of bag B removed from a center portion of bag B.

It should be noted that the configuration of storage container 24 including but not limited to the number of walls can be readily varied as desired.

FIG. 8

Referring to FIG. 8, an alternative form of storage and liquid dispensing unit D is illustrated in one of many possible configurations. Storage and liquid dispensing unit D is similar to liquid storage and liquid dispensing unit A and, therefore, only the differences will be described hereinafter. Specifically, base 50 of storage and liquid dispensing unit D includes a well-like depression 52 configured to minimize the residual water in the liquid retaining bag.

While this invention has been described as having a preferred design, it is to be understood that the preferred design can be further modified or adapted following in general the principles of the invention and including but not limited to such departures from the present invention as come within the known or customary practice in the art to which the invention pertains. The claims are not limited to the preferred embodiment and have been written to preclude such a narrow construction using the principles of claim differentiation.
