Abstract

A dispenser for pasty compositions, having a housing with a piston which is displaceable only in the emptying direction and an actuating handle on the outside by which action can be effected on a pump element which can be depressed in the direction of the piston. The pump element has an inlet valve and an outlet valve, the outlet valve being arranged in the actuating handle, the outlet valve being furthermore spring-urged into its closed position by means of spring elements which are developed thereon and extend into the inside of the dispenser. This provides for an embodiment which is simple to manufacture and advantageous in use. The spring elements are developed as spring legs which are formed free standing directly on a valve plate and rest against a collar of the actuating handle.
