Abstract
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).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
113 words
A replacement cartridge in combination with a shaver having a shaving fluid application device comprising a reservoir in said cartridge for holding shaving fluid; means defining a fluid path extending between said cartridge and said application device, said fluid path being sealed from ambient air; coupling means including mating parts on said cartridge and said shaver for connecting said cartridge to said shaver and for permitting limited relative reciprocatory movement between said shaver and said cartridge; and shaving fluid feeding means including said means defining said fluid path and responsive to reciprocatory motion between said shaver and said cartridge to feed shaving fluid from said reservoir through said fluid path to said shaver.
Claim 2
Dependent Claim
113 words
A replacement cartridge in combination with a shaver having a shaving fluid application device comprising a reservoir in said cartridge for holding shaving fluid; means defining a fluid path extending between said cartridge and said application device, said fluid path being sealed from ambient air; coupling means including mating parts on said cartridge and said shaver for connecting said cartridge to said shaver and for permitting limited relative reciprocatory movement between said shaver and said cartridge; and shaving fluid feeding means including said means defining said fluid path and responsive to reciprocatory motion between said shaver and said cartridge to feed shaving fluid from said reservoir through said fluid path to said shaver.
Claim 3
Dependent Claim
16 words
A cartridge and shaver according to claim 1 wherein said coupling means includes a self-actuating latch.
Claim 4
Dependent Claim
26 words
A cartridge and shaver according to claim 1 wherein said feeding means comprises a manually operated pump actuated by reciprocating said cartridge relative to said shaver.
Claim 5
Dependent Claim
