A multicomponent cartridge (1) which is designed for single use, includes a first supply chamber (6) for a first component (8), a second supply chamber (7) for a second component (9), wherein the first supply chamber (6) is separate from the second supply chamber (7).The first supply chamber (6) is arranged coaxially around the second supply chamber (7) and forms a ring space (10), wherein a first piston (3) is movably arranged in the first supply chamber (6) and a second piston (4) is movably arranged in the second supply chamber (7). The first and second pistons (3, 4) are movable by means of a plunger (5) to simultaneously discharge the two components (8, 9). A guide element (11) is provided to guide the first piston (3) in the first supply chamber (6) and to guide the second piston (4) in the second supply chamber (7). The guide element (11) contains a discharge opening (13) through which the first component (8) can be discharged out of the first supply chamber (6) and the guide element (11) is arranged in a housing (2). The guide element (11) is movable relative to the housing (2) by means of a movement element (12) whereby the discharge opening (13) can be freed. |
