ABSTRACT:
A cartridge assembly for dispensing flowable masses includes axially extending containers each holding a separate flowable mass and a discharge member for dispensing the flowable masses from the containers. The discharge member and the containers are separate parts assembled into a unit. During storage and transport, the containers are closed and the discharge member is mounted on one end of the containers. When the cartridge assembly is to be used, the unit is inserted into a dispensing device. The discharge member and the containers are displaced relative to one another so that the discharge member moves against one end of the containers for forming openings. The other ends of the containers contain pistons which are pressed by the dispensing device toward the openings in the other ends of the containers forcing the flowable masses into the discharge member from which they are dispensed.
