A cutting member for a shaving razor includes an elongated blade portion that tapers to a cutting edge, an elongated base portion that is integral with the blade portion, and a bent portion, intermediate the blade portion and the base portion. In some implementations, at least part of the cutting member has a thickness of at least about 0.005 inch (0.127 millimeter).

Cutting members for shaving razors

This invention relates to methods and systems for attaching components to strips of material to form assemblies, e.g., a system for fastening pre-sharpened razor blades to individual support strips on a continuous band of material, such as a metal, to form discrete blade assemblies.

Systems for producing assemblies

A shaving razor cartridge including a housing having an upper surface, a housing opening in the upper surface and side surfaces extending downward from the upper surface, blades mounted in the opening and supported by the housing, and a retaining clip on the upper surface having a clip opening around the housing opening. The retaining clip is made of flat painted sheet metal that has been drawn so as to provide an upper surface extending outward of the clip opening and side surfaces extending downward over the side surfaces of the housing. The paint on the sheet metal has sufficient delamination properties to pass a delamination test involving drawing a piece of flat painted sheet metal such that the paint is compressed greater than 35% and inspecting the resulting drawn piece of sheet metal to see there has been delamination of the paint.

Razor cartridge with painted and drawn retaining clip

A safety razor system includes an elongated housing pivotably attached to a member connecting the housing to a handle. The housing is substantially rectangular, having arcuate end portions. A plurality of razor blades and a guard member extend from the upper surface of the housing and an annular retainer clip is disposed about the periphery of the housing serving to retain the blades onto the housing and position the blades relative to the guard member. The connecting member pivotably supports the housing by four coaxial bearing surfaces contacting mating surfaces on the housing during rotation of the housing relative to the connecting member.
