  • Patent number: 9409301
    Abstract: A cap for a shaving head of a shaving apparatus has a skin contacting surface including at least two annular corrugations. The shape of the skin contacting surface of the cap is adapted to realizing a high feeling of comfort for a user of the shaving apparatus. A factor contributing to the feeling of comfort is that an annular central surface of an outermost corrugation has an orientation that is out of line with an expected course of an imaginary smooth flowing plane following a central surface of an adjacent corrugation, where a drooping configuration of the central surface of the outermost corrugation with respect to the central surface of the adjacent corrugation is realized.
