ABSTRACT:
A one-way valve for a leg urinal or similar container comprising a thin, elastic tube formed with a permanent spiral twist giving it a memory that positively closes the tube against liquid backflow. The tube is nonetheless highly sensitive to internal pressure and unwinds to open the tube and permit forward liquid flow or even tiny volumes of liquid. The tube is stretch fit on an inexpensively molded nipple member and the tube and nipple member form a unit that is readily operationally insertable into and removable from the container to be discarded and replaced or to permit easy access for cleaning the container.
