Abstract:

A razor blade cartridge includes a plastic body having a leading edge, a trailing edge, and a series of guard ribs integrally molded with the plastic body and extending between the leading and trailing edges of the plastic body. The razor blade cartridge also includes one or more cutting blades encompassed by the plastic body, each of the cutting blades including a cutting edge facing the leading edge of the plastic body. The guard ribs, which cover the cutting edges of the cutting blades, reduce friction as the cutting blades pass over a skin surface and minimize the likelihood of nicks and cuts while shaving.
