Publication number: 20240123642Abstract: Razors cartridges including a guard, a cap, and at least two blades with parallel sharpened edges located between the guard and cap are provided. The first blade has a first color and a second blade has a second color, where the first color is different than the second color. The blade color corresponds to an attribute of the blade (e.g., low cut force) that the color is disposed on or an attribute of the razor cartridge (e.g., sensitive skin). The color of the blade corresponds to a target user of the razor cartridge (e.g., male or female). The first blade defines a blade edge near or nearest the guard and a second blade defines a blade edge near or nearest the cap.Type: ApplicationFiled: December 8, 2023Publication date: April 18, 2024Inventors: Laura XU, Kenneth James SKROBIS, Neville SONNENBERG, Ronald Richard DUFF, JR., Joseph Allan DEPUYDT

Patent number: 10118304Abstract: The present invention relates to razor blade cutting edges and methods of producing edges exhibiting improved shave performance longevity and lower cutting forces. Conventional razor blades have increasing cutting forces with use due to the outer coating wear and adhesion loss. Blade edges produced according to the novel process exhibit significantly lower cutting forces when subjected to wool felt cutting shaving simulation, which correlates to more comfortable shaves initially and over the life of the blades. The present invention treats razor blade edges having a first adherent polyfluorocarbon coating with a first solvent to partially remove the polyfluorocarbon coating, adds a second polyfluorocarbon coating, heats, and treats the blade edge with a second solvent providing a final blade edge having a thin, uniform polyfluorocarbon coating.Type: GrantFiled: July 1, 2015Date of Patent: November 6, 2018Assignee: The Gillette Company LLCInventors: Ronald Richard Duff, Jr., John Joseph Nisby, Kenneth James Skrobis, Joseph Allan Depuydt

Publication number: 20170341250Abstract: A razor blade having a substrate with a cutting edge being defined by a sharpened tip. The substrate has thicknesses of 1.60-1.75 micrometers and 9.25-10.00 micrometers measured at a distance of four and forty micrometers from the blade tip, respectively. A ratio of the thickness measured at four micrometers to the thickness measured at forty micrometers is between 0.165-0.185. The substrate thickness is about 2.70-3.00 micrometers at eight micrometers from the blade tip, about 4.44-5.00 micrometers at sixteen micrometers from the blade tip with a thickness ratio measured at four micrometers and eight micrometers between 0.56-0.62, and a thickness ratio measured at four micrometers and sixteen micrometers between 0.32-0.40. The blade edge shape is defined by equation w=adn where “a” is between 0.50-0.62 and “n” is between 0.76-0.80. An included angle of less than 7° is measured at a distance of forty micrometers or greater from the blade tip.
