Abstract

A razor cartridge is provided with a skin engaging structure at the cap and/or guard surface of the razor cartridge. The skin engaging structure has an array of closely spaced elongated protrusions integrally formed with a substrate. In use, the protrusions produce a pleasant tactile sensation tending to reduce shaving discomfort. The protrusions are formed by closely packed molded flexible filaments that can be less than 0.25 mm wide and have spacing between adjacent protrusions less than 0.2 mm. The protrusions can have a density greater than 5 protrusions per mm2. The skin engaging structure can be molded from e.g. an olefin polymer. The substrate can be integrally formed with a housing of the razor cartridge.
