Abstract
Abstract A holder for a razor blade and guard is directly mounted on the valve stem of an aerosol lather dispenser can which serves as a handle for the shaver. The valve stem has a bore communicating with a fan-shaped passageway formed in the holder for feeding the lather to the skin along the length of the cutting edge of the blade and in advance thereof. Pressure exerted as the guard is stroked along the skin serves to tilt the valve stem and release lather from the can.

Independent Claim
140 words
A self-lathering shaver comprising an aerosol can containing lather producing ingredients and having a tilt-to-dispense valve assembly including a projecting valve stem formed with an axial bore through which the lather is dispensed when the valve stem is tilted, a shaving head mounted on said valve stem for movement therewith, said shaving head having a razor blade and safety guard surface for a cutting edge of the blade, and passageway means formed in said shaving head communicating with said valve stem bore and having an elongated opening located beneath said blade cutting edge, said can serving as a handle for manipulating the shaving head and for pressing said safety guard surface against a shaving surface to tilt said valve stem and release lather from the can for delivery through said passageway means and said elongated opening to the shaving surface.
Claim 2
Dependent Claim
