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.
Claims18
A shaving aid delivery system for a shaving system, comprising:
- a razor head having at least one reservoir for holding a shaving aid;
- a heating apparatus disposed adjacent to said reservoir;
- an actuator coupled to said heating apparatus for initiating volumetric expansion of said shaving aid when activated;
- and
- an ejection port for issuing said shaving aid from said reservoir upon activation of said actuator.
A shaving aid delivery system for a shaving system, comprising:
- a razor head having a plurality of reservoirs for holding a shaving aid;
- a heating apparatus having an electrical source and plurality of resistors each disposed adjacent one of said reservoirs, each of said resistors being electrically coupled to a corresponding actuator which causes volumetric expansion of said shaving aid within each of said corresponding reservoirs when activated;
- a shaving strip disposed within said razor head and oriented to engage the skin of a user during a shaving stroke, said shaving strip being positioned relative to each of said reservoirs;
- and
- an ejection port disposed within each of said reservoirs for issuing said shaving aid from said reservoir into contact with said shaving strip upon activation of said actuator corresponding to each of said reservoirs.
A method of ejecting shaving aid from a razor head comprising the steps of:
- providing a razor head having:
- an electrical source;
- a reservoir for holding a shaving aid;
- a resistor coupled to said electrical source and disposed within said reservoir in contact with said shaving aid;
- a shaving strip disposed within said razor head and oriented to engage the skin of a user during a shaving stroke;
- an ejection port for directing said shaving aid from said reservoir into contact with said shaving strip;
- selectively activating said resistor to cause rapid volumetric expansion of said shaving aid such that said shaving aid dispenses from said ejection port into contact with said shaving strip.
