  • Patent number: 10780599
    Abstract: A functional polymeric cutting edge structure and methods for the manufacturing of cutting edge structures comprised of polymeric materials are provided. The cutting edge structures may be produced on a substrate having a blade body or blade support type. The polymeric material is produced by curing a precursor material activated by electromagnetic radiation wherein a wavelength of said radiation is about double a wavelength required to activate the precursor material. A razor blade for use in a razor cartridge or a blade box may be formed using the present invention.

  • Patent number: 10723032
    Abstract: The invention discloses utilizing isostatic-press (IP) processes apply a polymeric material (e.g, a PTFE foil) to uncoated razor blade edges forming thin, dense, and uniform coatings on blade edges which in turn exhibit low initial cutting forces correlating with more comfortable shaves. The isostatic press may be a hot isostatic press (HIP) or a cold isostatic press (CIP) or any other isostatic press process. The HIP conditions may include an environment of elevated temperatures and pressures in an inert atmosphere. The CIP conditions may include room temperature and elevated pressure. The polymeric material may be a fluoropolymer or non-fluoropolymeric material or any composite thereof. The lower surface of the polymeric material may be modified (e.g., chemical etching) to enhance adhesion to the blade edge. Two or more layers of polymeric material of similar or different properties may be isostatically pressed onto the uncoated blades.
