Abstract: 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.

Abstract: A razor assembly is provided that includes a razor cartridge with one or more razor blades, a shaving aid body, a handle, and a linkage pivotally connected to the handle. The linkage is connected to the razor cartridge and the shaving aid body in a manner such that the razor cartridge and the shaving aid body are moveable relative to the handle. Movement of one of the razor cartridge or the shaving aid body in a first direction causes the other of the razor cartridge or the shaving aid body to move in a second direction substantially opposite the first direction. As a result, the positions of the shaving aid body and the razor cartridge are continuously adjusted to maintain the contact surface of the shaving aid body approximately co-planar with the cutting edges of the razor blades within the razor cartridge.
