Mixing capsule and method for activating the same

摘要

A mixing capsule for a two-component mixture comprises a preferably cylindrical container part (13). An axially displaceable piston (15) is guided within the container part (13). An opening (25) is provided on the front face of the piston (15) and leads into a liquid receptacle (23) with a burstable wall or membrane (29). The membrane (29) closes the opening (25) in the non-activated condition of the capsule (11. The hollow (35) between the front faces of the container part (13) and the piston (15) constitutes a mixing chamber (35). The activation part (33) can be displaced by means of activation pin (37) that closes the discharge nozzle (19) in the non-activated condition. In the activated condition of the capsule the activation part (33) is to all intents and purposes completely accommodated within the liquid receptacle.
