Abstract

A housing is formed with both an outlet port and an internal fluid chamber that communicates via a passageway with the outlet port. A tube provides communication between the fluid chamber in the housing and a reservoir of the material that is to be dispensed by the pump. A flexible frustroconical skirt or diaphragm having a valved opening is located between the tube and both the fluid chamber and the outlet port. An integral upper portion of the diaphragm initially obstructs the outlet port. When an actuating cap is depressed, material within the fluid chamber is compressed until a minimum predetermined chamber pressure is achieved, and the skirt or diaphragm is flexed from its normal position to a discharge position.
