Abstract
A hand pump fabricated entirely from plastic components for dispensing liquids, is provided. The hand pump includes an actuator, a closure, a housing having a lower check valve, and a piston having an integrated upper check valve in the form of an inverted cone suspended within a cylinder. An elastic, dome shaped, plastic return spring is utilized to return the actuator to its rest position after actuation. Used pumps do not require disassembly to be recycled.
