Abstract
A liquid dispensing device (10) for personal hygiene liquids is wall mounted with a plurality of containers (14) and valves (16). Each valve includes a valve plunger (60) with a head (62) having a flexible periphery (64) that provides increased bypass of liquid upon harder pressing and faster motion of the plunger. The valve has a seat (74) that presses the flexible periphery (64) against the valve inner cylindrical wall (54) of the valve bore (52) at the end of the return stroke. Each valve is also provided with a check valve (90) in an inlet port of the valve to restrict fluid flow back into the container upon actuation of the plunger. Each check valve is provided with a notch (100) that allows some restricted fluid flow of liquid back into the supply container (14) upon excessive pressure with in the valve bore (52).
