TW544390B - Shaving aid strip for razor cartridge - Google Patents

Abstract

The present invention is directed to a razor cartridge (14) with a solid polymeric shaving aid strip (22). The razor cartridge has a blade (18) (one or more) and a skin-engaging portion in proximity to the blade. The skin-engaging portion includes a solid polymeric shaving aid strip (22) having an upper exposed surface which contacts the skin during shaving. The shaving aid strip includes a first exposed lengthwise-extending portion (24) containing a lubricious water-soluble polymer and an adjacent, second exposed lengthwise-extending portion (26) containing a lubricious water-soluble polymer. The first portion contains a greater amount of the lubricious water-soluble polymer than the second portion, and the first portion is adapted to wear at a faster rate than the second portion during shaving. This construction enables the strip to release more of the lubricious water-soluble polymer for a longer time period (i.e., for more shaves) than conventional shaving aid strips.
