Abstract
Abstract A valve assembly is attached to the spout of a water bottle which is used in liquid dispensing devices common in households and offices. The assembly combines a sleeve-like housing and a valve for preventing water spillage particularly when the bottle is being hoisted and inverted onto the dispensing device. An elongated actuator stem unseats a valve head section from sealing engagement with the housing as the bottle is lowered into the device. The valve assembly is releasably attached to the bottle spout and can be reused repetitively.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
131 words
A liquid container with a spout and discharge outlet in combination with a valve assembly, said valve assembly comprising: a valve housing enclosing said outlet having attachment means for releasable securement to said spout, said housing providing a central aperture in communication with said outlet, said aperture defined by a sleeve-shaped sidewall with an inner wall surface; and, a valve means controlling liquid flow through said aperture comprising a valve head section having a ring part for sealing engagement with said inner wall surface and an actuator stem comprising segments spaced-apart adjacent said inner wall surface and extending from said ring part a predetermined distance past said outlet whereby movement of said stem will provide a corresponding movement of said head section for seating and unseating said section from said aperture.
Claim 2
Dependent Claim
131 words
A liquid container with a spout and discharge outlet in combination with a valve assembly, said valve assembly comprising: a valve housing enclosing said outlet having attachment means for releasable securement to said spout, said housing providing a central aperture in communication with said outlet, said aperture defined by a sleeve-shaped sidewall with an inner wall surface; and, a valve means controlling liquid flow through said aperture comprising a valve head section having a ring part for sealing engagement with said inner wall surface and an actuator stem comprising segments spaced-apart adjacent said inner wall surface and extending from said ring part a predetermined distance past said outlet whereby movement of said stem will provide a corresponding movement of said head section for seating and unseating said section from said aperture.
