Abstract
A two-component piston for a cartridge includes a piston cover as the first component and a piston body as the second component. The piston has a first side and a second side, and a rear side of the piston cover arranged adjacent to at least a part of the piston body. A front side of the piston cover is arranged at the first side, and the rear side of the piston cover includes a valve member. The valve member is to be received within the piston body and to extend into the piston body towards the second side. The piston cover is configured to be moved relative to the piston body on actuation of the valve member and the piston cover is non-releasably connected to the piston body.
