Personal hygiene liquids dispenser

A liquid dispenser valve characterized by:

• a housing having an inlet connectable to a supply container, a cylinder sized to receive a plunger head and a discharge nozzle axially positioned along a forward position in said cylinder;
• a check valve mounted in said inlet to restrict the flow of liquid upstream out of said inlet;
• a plunger mounted for axial movement in said cylinder;
• a return spring interposed between the plunger and a closed axial end of said cylinder for resiliently biasing and moving said plunger forwardly for a return stroke to a first axial position between said inlet and said discharge outlet and to allow a stroking motion to a rearward second axial position toward said inlet;
• said plunger having a head with a flexible periphery with an inner wall and outer wall, the flexible periphery when in the first axial position has its outer wall abuts against the cylinder wall to form a seal against leakage of liquid from said container to said discharge nozzle and when moved rearwardly to said second position flexed inwardly to allow liquid to flow by said piston head from said inlet to said discharge spout;
• said plunger having a plunger rod connected to said head that extends out of a front end of said cylinder and attached to a push button for manual operation of said plunger;
• a closure cap removably connected to a front end of said housing and about said plunger rod and having seals interposed between itself and said cylinder wall and said plunger rod;
• a seat for said inner wall of said periphery for abutting said inner wall of the periphery of said plunger head when said plunger head is in said first axial position to bias said periphery outwardly to abut said cylinder wall and form a seal within said cylinder to prevent fluid from passing to said discharge nozzle when said plunger rests in said first axial position.
