Abstract
A disposable razor blade assembly made up of a cartridge having blade means and including a shaving aid which expands when wet located on the cap portion of the razor blade assembly is combined with a removable, reusable overcap. The overcap forms a chamber which protects the user and the razor blade assembly of the safety razor and also includes a hood member integrally connected to the top wall of the overcap and extending over the shaving aid to provide clearance between the overcap and the razor blade assembly when the shaving aid has expanded.

A safety razor system comprising:
- a razor blade assembly having a predetermined width made up of a cartridge having a guard member and a blade means, said blade means being permanently mounted between a platform and a cap, said cap including a water-activated shaving aid disposed on a surface of said cap behind said blade means, said shaving aid expanding with respect to said surface of said cap, when wet;
- and
- a one-piece, integrally molded overcap having a chamber, said chamber having a transverse dimension substantially that of the width of the razor blade assembly and extending in height to cover said guard member and said blade means, said chamber including a substantially planar top wall and a bottom wall laterally displaced from said top wall, first and second end walls connecting said top wall to said bottom wall for preventing movement of said razor blade assembly into or out of said chamber in a transverse direction, and a hood member integrally connected to said top wall, said hood member extending over the entire surface of said shaving aid and exiting upward from the planar surface of said top wall and directed away from said chamber such that said shaving aid, when expanded, has sufficient clearance to prevent contact between said expanded shaving aid and said hood member.
