The mixing device is used for mixing multicomponent materials or for homogenizing compositions which are contained in a cartridge (10) which is closed by a piston (15) having a passage opening (19). The latter is primarily closed by the shaft (22) of a mixing member (20). Said shaft (22) may be coupled to a rod (23). By a drive or by manual operation, the rod (23) may be rotated and moved axially at the same time. While the piston (15) stays, where it is, the mixing member (20) is moved through the cartridge (10). Upon termination of the mixing operation, the mixing member (20) is locked at the piston (15) by a holding member (32) in order to unscrew the rod (23) from the mixing member. Subsequently, the cartridge may be inserted into a squeezing tool in which the piston (15) is advanced for squeezing out the composition.

Mixing device for mixing or homogenizing pasty or flowable compositions comprising a tubular cartridge (10), having at its one end a front wall (11), while its other end (12) is open, a mixing member (20) accommodated in the cartridge (10) and connected to a rod (23) extending out of the open cartridge end, and a piston (15) for squeezing out the cartridge content, characterized in that the piston (15) has an axial passage opening (19) for the rod (23) or for a shaft (22) projecting from the mixing member (23), the rod (23) is detachably connected to the mixing member (20), the piston (15) includes a holding member (32), and said holding member (32) defines means for retaining the mixing member (20) against rotation as said mixing member (20) is separated from the rod (23).
