  • 226;

    );

    in which container (50) a piston (90) is displaceably arranged so that by means of pressure upon the distal end of said piston (90), liquid can be expelled from the container (50);

    comprising a tappet (92), displaceably arranged in the housing (42), which is configured for contact against the distal end of the piston (90) and which enables transfer of a force to the piston (90) in the proximal direction;

    and comprising a member (91), associated with the tappet (92) and displaceable relative thereto, which at its proximal end region can be joined to the piston (90) in such a way that it enables the transfer of a force in the proximal direction and the transfer of a force in the distal direction to the piston (90).
