Abstract
Abstract A liquid dispensing apparatus is provided for use in combination with rigid or semi-rigid inverted liquid containers. The liquid dispensing apparatus is comprised of a base portion that provides a stable platform for the combination, a coupling extending up from the base portion that is inserted into the neck of the open liquid container to provide a seal around the neck and to provide an opening to discharge the liquid, and a spigot with a valve in communication with the opening to control the flow of liquid. A stabilizing arm extending from the base portion contacts the bottom of the liquid container and, in conjunction with the coupling, secures the liquid container to the liquid dispensing apparatus. The base portion is also designed to contain any liquid that may leak from the coupling.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
317 words
A liquid dispensing appartus, for use in combination with an inverted liquid container, comprising: a base portion; a mounting bore centrally located in said base portion; a coupling means attached to and extending up from said base portion to form an integral unit with said base portion for insertion into the open neck of the liquid container to provide a press-fit secure seal with the liquid container; wherein said coupling means is a nozzle composed of a unitary piece of material that is slightly flexible while retaining its general shape, wherein the nozzle comprises: a conic shaped top portion extending above the surface of said base portion, a cylindrically shaped lower portion friction fitted in said mounting bore of said base portion, and a tapered center cavity extending from the apex of said nozzle top portion to an intermediate position in said nozzle lower portion; wherein said base portion includes an upper portion and a lower portion said base portion subtending an area greater than that subtended by the liquid container and said lower base portion having a square perimeter, said upper portion having a generally circular shape which is centered on said lower base portion wherein the upper base portion consists of a means for containing leaks from said coupling means, said means for containing leaks from said coupling means comprises a concave top surface of said upper portion concentric with said coupling means whereby a sink is formed surrounding said coupling means; a longitudinal bore extending from said tapered center cavity of said coupling means to the side of said base portion so that the liquid may be discharged from the container; a valved spigot in communication with said longitudinal bore at the side of said base portion to control the flow of liquid; and a stabilizing means extending from said base portion for contact with the bottom surface of the inverted liquid dispensing apparatus.
Claim 2
Dependent Claim
317 words
A liquid dispensing appartus, for use in combination with an inverted liquid container, comprising: a base portion; a mounting bore centrally located in said base portion; a coupling means attached to and extending up from said base portion to form an integral unit with said base portion for insertion into the open neck of the liquid container to provide a press-fit secure seal with the liquid container; wherein said coupling means is a nozzle composed of a unitary piece of material that is slightly flexible while retaining its general shape, wherein the nozzle comprises: a conic shaped top portion extending above the surface of said base portion, a cylindrically shaped lower portion friction fitted in said mounting bore of said base portion, and a tapered center cavity extending from the apex of said nozzle top portion to an intermediate position in said nozzle lower portion; wherein said base portion includes an upper portion and a lower portion said base portion subtending an area greater than that subtended by the liquid container and said lower base portion having a square perimeter, said upper portion having a generally circular shape which is centered on said lower base portion wherein the upper base portion consists of a means for containing leaks from said coupling means, said means for containing leaks from said coupling means comprises a concave top surface of said upper portion concentric with said coupling means whereby a sink is formed surrounding said coupling means; a longitudinal bore extending from said tapered center cavity of said coupling means to the side of said base portion so that the liquid may be discharged from the container; a valved spigot in communication with said longitudinal bore at the side of said base portion to control the flow of liquid; and a stabilizing means extending from said base portion for contact with the bottom surface of the inverted liquid dispensing apparatus.
Claim 3
Dependent Claim
60 words
In the liquid dispensing aparatus of claim 1, wherein said spigot is provided with a plunger-type valve for equalizing the pressure within the liquid container with that of the atmosphere by allowing the passage of air into the liquid container through said longitudinal bore and opening in said coupling so that liquid will flow continually from the liquid dispensing apparatus.
Claim 4
Dependent Claim
229 words
A liquid dispensing appartus, for use in combination with an inverted liquid container, comprising: a base portion including a stable support; a coupling means extending up from said base portion for insertion into the open neck of the liquid container to provide a secure seal; an opening in said coupling means so that the liquid may be discharged from the container; a mounting bore in said base portion to accommodate said coupling means; a longitudinal bore extending from said opening of said coupling means to the side of said base portion; a valved spigot in communication with said longitudinal bore at the side of said base portion to control the flow of liquid; and a stabilizing means extending from said base portion; wherein said stabilizing means is an arm composed of a resilient material with a circular cross-section, comprising: a coupling section pivotably mounted to the side of said base portion so that said arm can be rotated relative to said base and the liquid container for insertion and removal of the liquid container from the combination, a vertical section extending up from said coupling section having a height substantially equal to that of the liquid container, and a horizontal section extending perpendicularly from said vertical section, wherein said horizontal section of said arm is in contact with and extends diametrically across the bottom of the inverted liquid container.
Claim 5
Dependent Claim
229 words
A liquid dispensing appartus, for use in combination with an inverted liquid container, comprising: a base portion including a stable support; a coupling means extending up from said base portion for insertion into the open neck of the liquid container to provide a secure seal; an opening in said coupling means so that the liquid may be discharged from the container; a mounting bore in said base portion to accommodate said coupling means; a longitudinal bore extending from said opening of said coupling means to the side of said base portion; a valved spigot in communication with said longitudinal bore at the side of said base portion to control the flow of liquid; and a stabilizing means extending from said base portion; wherein said stabilizing means is an arm composed of a resilient material with a circular cross-section, comprising: a coupling section pivotably mounted to the side of said base portion so that said arm can be rotated relative to said base and the liquid container for insertion and removal of the liquid container from the combination, a vertical section extending up from said coupling section having a height substantially equal to that of the liquid container, and a horizontal section extending perpendicularly from said vertical section, wherein said horizontal section of said arm is in contact with and extends diametrically across the bottom of the inverted liquid container.
Claim 6
Dependent Claim
29 words
In the liquid dispensing appartus of claim 3 wherein said base portion is provided with a means for containing leaks from said coupling means within the liquid dispensing appartus.
Claim 7
Dependent Claim
49 words
In the liquid dispensing apparatus of claim 4 wherein said means for containing leaks from said coupling means comprises a large bore in the top surface of said base portion, said large bore being concentric with said coupling means; and said coupling means being located in said large bore.
