Thin Film Coating Of Blades
US Patent:
2011020, Sep 1, 2011
Filed:
May 12, 2011
Appl. No.:
13/105958
Inventors:
John Madeira - Assonet MA, US

International Classification:
C23C 14/34
US Classification:
20419216
Abstract:
The present invention relates to a process for forming a razor blade. The process includes the steps of: a) providing a substrate, b) forming a wedge-shaped sharpened edge on the substrate that has an included angle of less than thirty degrees and a tip radius of less than 1,000 angstroms, c) placing the substrate in a vacuum chamber, d) placing a first solid target in the vacuum chamber, e) providing a gas to be ionized in the vacuum chamber, and f) generating ions from the first solid target by applying a negative voltage to the first solid target in pulses, the ions forming a thin film coating on the wedge-shaped sharpened edge on the substrate.
Atomic Layer Deposition Coatings On Razor Components
US Patent:
2011001, Jan 20, 2011
Filed:
Jul 17, 2009
Appl. No.:
12/504991
Inventors:
John Madeira - Assonet MA, US
Neville Sonnenberg - Newton MA, US
Neville Sonnenberg - Newton MA, US
International Classification:
B26B 21/60, C23F 1/00
US Classification:
3034654, 216 37
Abstract:
A novel application of the atomic layer deposition (ALD) process for producing a conformal coating on a razor blade is disclosed where a uniform, conformal, dense coating is deposited on an entire surface of a blade flank and at least a portion or an entire surface of a blade body. To improve the shaving ability of the coated blade edge (e.g., decrease the blade tip radius), the ALD-produced coating may be etched during, after, or both during and after, the ALD process.

The Gillette Company - Boston MA
International Classification:
B26B 2100, B26B 2154
US Classification:
30 50
Abstract:
A razor blade includes a substrate with a wedge-shaped edge, an interlayer of material selected from the group consisting of silicon, silicon carbide, vanadium, tantalum, nickel, niobium, and niobium-molybdenum alloy and alloys of such materials on the tip and flanks of the wedge-shaped edge, the thickness of the interlayer preferably being in the range of about 50-500 angstroms, and a layer of diamond or diamond-like carbon material on the interlayer that preferably has a thickness of about two thousand angstroms and that defines a tip radius of less than about 1000 angstroms.

International Classification:
B26B 2106
US Classification:
30 50
Abstract:
A shaving system with a blade member with a cutting edge of wedge shape that is defined by main facets with an included facet angle in the range of 10. degree. -17. degree. in the region forty micrometers from the cutting edge. The blade is mounted between leading and trailing skin-engaging surfaces so that the blade tangent angle is less than 20. degree. and the interior main facet of the blade is disposed at an angle of more than 150. degree. to a reference line that extends from the cutting edge of the blade to the skin-engaging point next forward of the blade edge.
