Abstract
A replacement cartridge (1) for a shaver with an application device has an application preparation reservoir (2) and means for feeding the application preparation such as a small manually operated pump (3), and a connecting piece (10). The replacement cartridge is fixed to the shaver by a coupling between the connecting piece (10) and a counterpart (4). In the new state of the replacement cartridge, the interior of the small pump (31) is filled with application preparation. The integration of the small pump into the replacement cartridge (1) and its initial filling with preparation permits a simple design of the pump. The pump has a pump chamber (31) whose walls have elastically deformable points and two one-way valves (32, 33). A preparation reservoir has a hollow body whose interior is subdivided into a preparation chamber (22) and an air chamber (23) by a movable plunger (21).
