摘要

The device has a cartridge displaced into an open discharging position. A step-by-step system (11) is provided for indicating and registering discharging actuations. A step-by-step system-housing (34) is formed with a smooth walled-outer surface in an outer surface area. The surface area is turned way from an extension direction, and has a form fit-guide (41) that is provided as a rotary protection towards another housing. The guide forms an evenly wide free annular gap to a wall of the latter housing through a remaining circumference of the surface.
