Abstract
Abstract This disclosure pertains to a container having a self closing inexpensive valve located in the lowermost extremities thereof. The valve comprises a pair of resilient sheets having a portion of their surfaces biased in touching engagement by the manner in which the sheets are formed and mounted, and by the pressure exerted on opposed surfaces supplied by the liquid within the container. An elongated rod hingably secured to the container forces the valve-like surfaces into an open position permitting the liquid within the container to be dispensed, utilizing gravity therefor. Removal of the rod from between the valve faces permits the valve to close terminating the liquid discharge.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
240 words
The liquid dispensing container comprising a container for the storage of liquid therein, said container having an opening, self closing valve means for selective dispensing of said liquid from said container, said valve means fixedly secured to the interior surface of said container adjacent the entire marginal edges of said opening, said valve means self biased into a closed position preventing said dispensing of said liquid, said valve means responsive to the presence of said liquid within said container, said liquid when within said container urging said valve means in said closed position, valve opening means for manually manipulating said valve means into an open position, wherein said valve means is heat sealed to said container, wherein said valve means is disposed within the liquid storing portion of said container, wherein said valve means comprises a flexible thermoplastic material having a generally tubular shape, one end of said tubular shape having an outwardly radially extending flange, the other end of said tubular shape having the innermost surfaces adjacent thereto in touching engagement, said innermost surfaces being disposed in said touching engagement by the thermoplastic properties comprising said flexible material, wherein said valve opening means comprises a tapered rod, hinging means for hingeably affixing said tapered rod to the outermost surface of said container, biasing means for biasing said tapered rod outwardly from said outermost surface, said tapered rod being disposed through said opening when said biasing means is manually overridden.
Claim 2
Dependent Claim
240 words
The liquid dispensing container comprising a container for the storage of liquid therein, said container having an opening, self closing valve means for selective dispensing of said liquid from said container, said valve means fixedly secured to the interior surface of said container adjacent the entire marginal edges of said opening, said valve means self biased into a closed position preventing said dispensing of said liquid, said valve means responsive to the presence of said liquid within said container, said liquid when within said container urging said valve means in said closed position, valve opening means for manually manipulating said valve means into an open position, wherein said valve means is heat sealed to said container, wherein said valve means is disposed within the liquid storing portion of said container, wherein said valve means comprises a flexible thermoplastic material having a generally tubular shape, one end of said tubular shape having an outwardly radially extending flange, the other end of said tubular shape having the innermost surfaces adjacent thereto in touching engagement, said innermost surfaces being disposed in said touching engagement by the thermoplastic properties comprising said flexible material, wherein said valve opening means comprises a tapered rod, hinging means for hingeably affixing said tapered rod to the outermost surface of said container, biasing means for biasing said tapered rod outwardly from said outermost surface, said tapered rod being disposed through said opening when said biasing means is manually overridden.
Claim 3
Dependent Claim
52 words
The liquid dispensing container as claimed in claim 1, further comprising a liquid directing surface, said liquid directing surface for directing the flow of said liquid discharge from said container along a generally outwardly downwardly extending path from the outermost surface of said container adjacent the lowermost marginal edges of said opening.
