A shaving aid delivery system for a shaving system includes a razor head having a resilient reservoir for holding a shaving aid and a piezoelectric ceramic disposed adjacent the resilient reservoir. The delivery system also includes a shaving strip disposed within the razor head, an actuator and an ejection port. The shaving strip is oriented to engage the skin of a user during a shaving stroke and the actuator electrically couples to the piezoelectric ceramic such that, upon activation, the actuator causes deformation of the piezoelectric ceramic which, in turn, deforms the resilient reservoir and forces the shaving aid from the reservoir through the ejection port. Alternatively, the actuator may include a shape memory alloy which, upon transformation between states, deforms the reservoir and forces the shaving aid from the reservoir through the ejection port.

Razor having deformable shaving aid ejection system and method of ejecting shaving aid

A shaving aid delivery system for a shaving system includes a razor head having a reservoir for holding a shaving aid and a heating apparatus disposed adjacent the reservoir. The delivery system also includes a shaving strip disposed within the razor head, an actuator and an ejection port. The shaving strip is oriented to engage the skin of a user during a shaving stroke and the actuator electrically couples to the heating apparatus to cause volumetric expansion of the shaving aid when activated. The ejection port directs the shaving aid from the reservoir onto the shaving strip upon activation of the actuator.

Razor having thermo-electric shaving aid ejection system and method of ejecting shaving aid

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.
