Abstract
Multi-component mixing capsule having an ejection device, in particular for dental purposes. A receptacle part (1) forming a mixing chamber (5) contains a piston (2) which for its part comprises an accommodation chamber (31) for a film container (32) and a ram (3). To enable the ram (3) to be pushed forward inside the piston (2) in order to transfer the film container contents into the mixing chamber (5) without the piston (2) being displaced in the receptacle part (1), the piston (2) is provided on a portion protruding rearwards beyond the receptacle part (1) with a radial projection which is supported on the tool or on the rearward end face (17) of the receptacle part (1). Support ends as soon as the ram (3) has travelled the necessary distance in the piston (2) to empty the film container (32). For this purpose, the projection (22) may have the ability to be torn off from the piston or bent inwards.
