摘要

Device comprises a cartridge (1) with at least two parallel cylindrical chambers (2) for holding the components and a piston (3) for pressing out the components of each chamber. The chambers have outlet openings (5) covered by a cap (10) having an outlet tube (12) containing a mixing screw (13). The cap is moved from a position closing the outlet openings into a position releasing the outlet openings. The cap is moved into the open position by the pressure of the components during their pressing out. A transverse wall (7) extending toward the cap and attached to the mixing screw is provided on the cartridge between the outlet openings. An Independent claim is also included for a pressing out device used in the above device.
