Abstract
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.
