The system comprises, for example, an electric shaver (1) and a cartridge
(2) mounted in a chamber (12) of the shaver (1). The shaver (1) comprises
a shaving head (3) having drivable cutters (31) and an electric motor (11)
for driving the cutters (31) via a coupling pin (14). The cartridge (2)
comprises a reservoir (25) for holding an auxiliary fluid. This auxiliary
fluid may, for example, serve to reduce the friction between the shaving
head (3) and the skin of a user. The cartridge (2) has an outlet channel
(22) and a diaphragm pump (23) for feeding the auxiliary fluid from the
reservoir (21) to the outlet channel (22). For the actuation of the
diaphragm pump (23) the shaver (1) comprises a button (15) and a lever
(17) which is pivotable about a pivot (18). When the button (15) is
pressed the diaphragm pump (23) is actuated and a small amount of the
auxiliary fluid is applied to the skin of a user via an outlet opening
(32). The cartridge (2) has a key (50) which cooperates with a blocking
device (60), which is adapted to block the lever (17) by means of pins.
The key (50) has projections for positioning the pins of the blocking
device (60). In the absence of the correct key the lever (17) is blocked
and thus prevents the auxiliary fluid in the cartridge from being pumped
to the outlet opening (32).
