Patent number: 6651342Abstract: A shaving razor blade unit that has a plurality of blades and a guard that includes two groups of rows of elongated, elastomeric fins arranged generally parallel to the cutting edges of the blades. The first group of fins has tips with increasing elevation with respect to a plane passing through the cutting edges, and the second group of fins has tips of generally uniform position relative to the plane. Also disclosed are a guard with at least six rows of elongated, elastomeric fins arranged generally parallel to the cutting edges of the blades; a guard that includes at least five rows of elongated, elastomeric fins that are arranged generally parallel to the cutting edges of the blades and generally increase in elevation with respect to a plane passing through the cutting edges of the blades in going from fins further from the blades to fins closer to the blades; and fins that converge from a base portion to a tip portion at an included angle of less than 14 degrees.Type: GrantFiled: February 29, 2000Date of Patent: November 25, 2003Assignee: The Gillette CompanyInventor: Vincent P.

Patent number: 6298559Abstract: The present invention is directed to a razor cartridge with a solid polymeric shaving aid strip. The razor cartridge has a blade (one or more) and a skin-engaging portion in proximity to the blade. The skin-engaging portion includes a solid polymeric shaving aid strip having an upper exposed surface which contacts the skin during shaving. The shaving aid strip includes a first exposed lengthwise-extending portion containing a lubricious water-soluble polymer and an adjacent, second exposed lengthwise-extending portion 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.Type: GrantFiled: December 14, 2000Date of Patent: October 9, 2001Assignee: The Gillette CompanyInventors: Michael J. Kwiecien, Vincent P. Walker, Jr.
