Abstract

A dispenser for pasty compositions, having a housing within which a piston displaceable in only the direction of emptying is arranged. An actuator enables a headpiece to act on a restorable wall which can be pressed in the direction towards the piston, the headpiece having a dispenser outlet opening. The wall forms an outlet tube the opening of which is coordinated to the outlet opening, and on which opening a stopper is formed which closes the outlet opening. The outlet opening is formed in the front side actuator and the actuator can act on the wall by means of the lever transmission.
