Patent number: 10413962Abstract: A method for making a bent razor blade is disclosed. The method includes: providing an elongated strip of stainless steel that can be 0.076 mm thick; hardening the strip; providing a cutting edge along an edge of the strip and providing coating(s) on the cutting edge. The stainless steel has a carbon content less than 0.60% and preferably between 0.45% and 0.55% by weight. The strip is separated lengthwise into discrete razor blades. The bent portion of the razor blade is then formed using a swivel bending process.Type: GrantFiled: May 15, 2018Date of Patent: September 17, 2019Assignee: Edgewell Personal Care Brands, LLCInventors: Henryk Bykowski, Stephan Fischer, Jochen Thoene

Publication number: 20130205595Abstract: A method of making a razor cartridge is provided. A housing of the razor cartridge has an elongated body having, integrally formed, a guard, a cap and an interior wall extending between the guard and the cap close to an end of the elongated body. An exterior wall extends outwardly of the interior wall and is joined to the interior wall by a film hinge. A portion of a body of a razor blade is positioned in a slot of the interior wall. The exterior wall is folded about the film hinge so that a lip of the exterior wall overlays an end portion of the cutting edge of the razor blade to secure to razor blade within the housing. The exterior wall is additionally secured to the elongated body. A razor cartridge is thus provided.Type: ApplicationFiled: February 12, 2013Publication date: August 15, 2013Applicant: Eveready Battery Company Inc.Inventors: Henryk Bykowski, Gerhard Ermertz, Stephan Fischer, Jochen Thoene

Patent number: 8186062Abstract: A razor cartridge is provided with a skin engaging structure at the cap and/or guard surface of the razor cartridge. The skin engaging structure has an array of closely spaced elongated protrusions integrally formed with a substrate. In use, the protrusions produce a pleasant tactile sensation tending to reduce shaving discomfort. The protrusions are formed by closely packed molded flexible filaments that can be less than 0.25 mm wide and have spacing between adjacent protrusions less than 0.2 mm. The protrusions can have a density greater than 5 protrusions per mm2. The skin engaging structure can be molded from e.g. an olefin polymer. The substrate can be integrally formed with a housing of the razor cartridge.Type: GrantFiled: March 17, 2008Date of Patent: May 29, 2012Assignee: Eveready Battery Company, Inc.Inventors: Stephan Fischer, Jochen Thoene

Publication number: 20080250647Abstract: According to one aspect of the present invention, a razor cartridge includes an outer shell, and a support structure. The outer shell defines a primary blade opening and a trimming blade opening. The support assembly is located at least partially inside the outer shell and includes at least one primary blade slot and a trim blade slot. A primary blade is located within each of the primary blade slots in the support assembly such that a cutting edge on the primary blade extends through the primary blade opening in the outer shell. A trim blade is located within the trim blade slot in the support structure such that a cutting edge on the trim blade extends through the trim blade opening in the outer shell.Type: ApplicationFiled: April 14, 2008Publication date: October 16, 2008Applicant: EVEREADY BATTERY COMPANY, INC.Inventors: Stephan Fischer, Jochen Thoene, Matthias Niggemann, Kelvin Stewart

Patent number: 7413078Abstract: According to one aspect of the present invention, a dispenser for one or more razor cartridges includes a base, two side walls, a front wall, a rear wall, a first divider, a second divider, a cover, and a side spring. The first divider is located between the front wall and the rear wall. The second divider is located between the first divider and the front wall, forming a chamber between the second divider and the first divider. The chamber is sized and shaped to receive at least a portion of a razor cartridge. The cover extends partially over the chamber between the first divider and second divider, and is sized to provide an opening through which the razor cartridge can be inserted into the chamber. The side spring extends widthwise into the chamber. The cover and the side spring frictionally engage the razor cartridge when inserted into the chamber.Type: GrantFiled: April 3, 2006Date of Patent: August 19, 2008Assignee: Eveready Battery Company, Inc.Inventors: Stephan Fischer, Jochen Thoene
