  • Patent number: 8642122
    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.

  • Patent number: 8628821
    Abstract: The invention discloses isostatic-pressing (IP) applied to polymer (e.g., PTFE) coated razor blade edges to produce thin, dense, and uniform blade edges which in turn exhibit low initial cutting forces correlating with a more comfortable shaves. The isostatic press utilized may be a hot isostatic press (HIP) or 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 HIP conditions may be applied to non-sintered coatings or sintered coatings or before or after a FlutecĀ® process is applied to coatings. CIP conditions may include room temperature and elevated pressure. The polymeric material may be a fluoropolymer or a non-fluoropolymer material or any composite thereof. It may be deposited initially by any method, including but not limited to, dipping, spin coating, sputtering, or thermal Chemical Vapor Deposition (CVD).

  • Publication number: 20130031794
    Abstract: This invention relates to a novel application of hard, low friction aluminum magnesium boride (AlMgB14, also known as BAM) based ceramic coatings to surfaces of razor components and in particular to blade edges of razor blades. On razor blade edges, these coatings may elevate blade performance, while also simplifying the manufacturing process.

  • Publication number: 20110203113
    Abstract: A razor cartridge having blades and a cap structure in back of the blades where the cap structure extending across the length of the blades includes at least one skin engaging element and at least one shaving aid portion. The skin engaging element may comprise fin elements, elongated protrusions, bumps, nubs, or any combination thereof, and may be flexible to engage the user's skin in back of the blades for a comfortable shave. The shaving aid portion serves to deliver at least one shaving aid material (e.g., lubricant) to the skin. The shaving aid portion may be a lubricating strip, a soap/solid, a foam or sponge filled with shaving aid material or any combination thereof. The cap structure provides a synergy between the skin engaging element and the shaving aid portion. A percentage contact to a user's skin of the skin engaging element is from about 20% to about 90%.

  • Patent number: 5406819
    Abstract: The invention relates to a method for forming and manufacturing the automobile rear axle housing from an integral steel tube, and to the special equipment for using the said method. The method involves cutting a longitudinal through opening in the center of the steel tube, expanding the opening with an expanding device and after expansion, roll-pressing or pressing the tube wall into the required form. The equipment designed for using this method comprises an operable die set, tube end thrust unit, opening expansion unit, roll-press unit and press unit. The use of this invention for making the automobile rear axle housing will omit the welding process, improve product quality, reduce manufacturing cost and the investment for equipment.
