Abstract
A shaving aid delivery system for a razor assembly includes a cartridge assembly having a reservoir for storing a fluid shaving aid and skin care topicals, and channels for communicating the shaving aid to a shaving surface of the cartridge assembly. A spring driven piston assembly drives shaving aid from the reservoir to the shaving surface. A clutch assembly controls the movement of the piston assembly, the clutch assembly being movable between an engaged position wherein the movement of the piston assembly is prevented and a released position wherein the movement of the piston assembly is permitted. The clutch assembly is movable to the released position in response to a force applied to the shaving surface of the cartridge. A visual indicator alerts the user as to the amount of shaving aid remains in the reservoir and when replacement is due.
