Abstract
Abstract A shaving apparatus for flat and contour shaving makes it possible to distribute in the form of a think film on the skin just prior to shaving a cosmetic or pharmaceutical preparation. It comprises an applicator part, a feed part and a blade part, the blade part and the applicator part together forming the razor head (1), while the feed part forms the razor handle (4). The preparation is applied by means of a roll (5) or a spatula-like part, on which rotates a thin film of the preparation supply shielded from the outside. The feed device comprises a preparartion reservoir (6) and a miniature pump (5), which is arranged in such a way that it can easily be operated during application by the fingers guiding the razor and consequently during shaving preparation is fed into the applicator. The blade part comprises at least one blade functionally cooperating with the applicator part.
