Problems solved by technology

This sacrificial role of the clip is advantageous as corrosion of the cutting edge of the blade becomes a safety hazard for the user, while corrosion of the clip will affect aesthetics and will most likely prompt the user to discard the cartridge before further damage can occur
However, in some circumstances, for example, if there is poor contact between the blade and the clip, corrosion of the blade and / or support may still occur

Embodiment Construction

[0016] see figure 1 , the supported blade 10 includes a blade 12 and a blade support 14 . The blade 12 is welded to the upper part 16 of the blade support. The blade support also includes a curved portion 18 and a lower portion 20 having a radius of curvature R of about 0.05 mm to about 0.15 mm. In some implementations, the blade support can have a thickness of about 0.10 mm to about 0.40 mm (eg, about 0.15 mm to about 0.30 mm). Generally, the blades are made of steel, such as stainless steel.

[0017] The blade support can be made of any desired metal, but is usually made of steel (eg carbon steel) or stainless steel. The blade support comprises an aluminum coating 21 on a lower surface 22 of the blade support. In general, the coating covers the entire lower surface of the blade support. Typically, the upper surface 23 of the blade support is not coated, as this tends to interfere with the formation of the weld 24 if conventional welding techniques are used. Furthermore...

Abstract

The present invention discloses supported blades (10) for use in shaving systems. The supported blades include a blade support (20) having a surface (22) that is coated with aluminum.

Description

technical field [0001] The present invention relates to a blade support for a shaving system. Background of the invention [0002] In recent years, razors with various numbers of blades have been proposed and commercialized in the patent literature, such as described in U.S. Patent 5,787,586, which generally describes the three-bladed Mach III razor that has been commercialized by The Gillette Company. One-type design. The blades of the Mach III razor are secured to the cartridge housing with aluminum clips. The clip extends above the blade and around the perimeter of the housing. The blade is welded to a stainless steel blade support which provides lateral support to the blade and has ends held in place by clips to securely secure the blade to the blade holder. [0003] The aluminum clip acts as an anode (the part that corrodes preferentially) in the galvanic couple formed by the clip and blade / support, thereby inhibiting corrosion of the steel blade and blade support. ...
