ABSTRACT:
A valve particularly suitable for use on disposable containers has a valve head on a flexible membrane. A simple lever moves the valve head to open the valve and deform the membrane. The shape of the membrane returns the valve head to a closed position upon release of the lever. Structure for restricting movement is provided for preventing excessive deflection of the membrane.
