Cartridge for plastic masses

Abstract

Abstract A cartridge body (11) contains a piston (14) which can be advanced in order to press the plastic mass contained in the cartridge body out of a discharge neck (13). At the rear end of the cartridge body (11), there are inwardly directed sawtooth-shaped projections (20) which allow the insertion of the piston (14) into the cartridge body (11) with elastic deformation but prevent the return movement of the piston (14). In this manner, the return movement of the piston is blocked without mounting or deformation operations still having to be carried out after the insertion of the piston (14) into the cartridge body (11). <IMAGE>
