Claims
- 1. A shaving aid delivery system for a razor assembly, which comprises:a) a cartridge assembly having a reservoir for storing a fluid shaving aid, and means for communicating the shaving aid to a shaving surface of the cartridge assembly; b) piston assembly movable from a first position to a second position for driving shaving aid from the reservoir to the shaving surface, said piston assembly being biased to the second position; c) clutch assembly for controlling the movement of the piston means, said 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, said clutch assembly being movable to the released position in response to a force applied to the shaving surface of the cartridge; and d) a handle.
- 2. The shaving aid delivery system of claim 1 wherein the cartridge assembly includes a cartridge head, and a flexible bladder connected to the cartridge head for at least partially containing the shaving aid.
- 3. The shaving aid delivery system of claim 2 further including a porous strip mounted to the cartridge head.
- 4. The shaving aid delivery system of claim 2 wherein the cartridge assembly further includes a cartridge body for housing the bladder.
- 5. The shaving aid delivery system of claim 3 wherein the means for communicating the shaving aid to the shaving surface comprises at least one channel extending between the reservoir and the porous strip.
- 6. The shaving aid delivery system of claim 1 wherein the piston assembly includes a plunger attached to a tubular shaft.
- 7. The shaving aid delivery system of claim 6 wherein the piston assembly further includes a spring at least partially disposed through a bore of the tubular shaft.
- 8. The shaving aid delivery system of claim 1 further including a yoke for supporting the cartridge assembly, the yoke being mounted to the handle.
- 9. The shaving aid delivery system of claim 8 wherein the clutch assembly includes the yoke, a leaf spring and a friction pad.
- 10. The shaving aid delivery system of claim 9 wherein the yoke includes a distal portion, a proximal portion, and an intermediate flexible portion between the distal and proximal portions, wherein the proximal portion is fixedly secured to the handle, and the distal portion is pivotably movable from a first yoke position to a second yoke position in response to pressure applied to the cartridge assembly, wherein the friction pad frictionally engages the piston assembly to prevent movement of the piston assembly when the yoke is in the first yoke position, and wherein the friction pad does not prevent movement of the piston assembly when the yoke is in the second yoke position.
- 11. The shaving aid delivery system of claim 10 wherein the yoke is biased to the first yoke position by the leaf spring.
- 12. The shaving aid delivery system of claim 9 wherein the handle comprises a first handle joined to a second handle part.
- 13. The shaving aid delivery system of claim 12 wherein the leaf spring is attached to the first handle part and the friction pad is attached to the second handle part.
- 14. The shaving aid delivery system of claim 3 wherein the porous strip comprises a strip of synthetic polymer having a pore size of from 5 microns to 20 microns.
- 15. The shaving aid delivery system of claim 1 further including means for indicating an amount of shaving aid remaining in the reservoir of the cartridge assembly.
- 16. A razor assembly comprising:a) at least one razor blade; b) a fluid shaving aid; c) a cartridge assembly having a support for mounting the at least one razor blade, a reservoir for storing the fluid shaving aid, and at least one channel for communicating the shaving aid from the reservoir to a shaving surface of the cartridge assembly; d) piston assembly movable from a first position to a second position for driving shaving aid from the reservoir to the shaving surface, said piston assembly being biased to the second position; e) clutch assembly for controlling the movement of the piston means, said 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, said clutch assembly being movable to the released position in response to a force applied to the shaving surface of the cartridge; and f) a handle.
- 17. The razor assembly of claim 16 wherein the shaving aid includes one or more materials selected from the group consisting of silicone oil, polyethylene oxide, non-ionic polyacrylamide, guar gum, depilatory agent, a silicone polyethylene oxide block copolymer, sodium lauryl sulphate, antiseptic, skin conditioner, blood coagulant, vitamin E, sodium pyruvate, sunflower oil, Dimethicone, C12-C15 alcohol benzoate, glycerin, cetyl alcohol, stearyl alcohol, jojoba oil, allantoin, aloe vera and sesame oil.
- 18. The razor assembly of claim 17 wherein the clutch assembly includes a yoke for supporting the cartridge assembly, a leaf spring and a friction pad.
- 19. The razor assembly of claim 18 wherein the yoke includes a distal portion, a proximal portion, and an intermediate flexible portion between the distal and proximal portions, wherein the proximal portion is fixedly secured to the handle, and the distal portion is pivotably movable from a first yoke position to a second yoke position in response to pressure applied to the cartridge assembly, wherein the friction pad frictionally engages the piston assembly to prevent movement of the piston assembly when the yoke is in the first yoke position, and wherein the friction pad does not prevent movement of the piston assembly when the yoke is in the second yoke position.
- 20. The razor assembly of claim 19 wherein the yoke is biased to the first yoke position by the leaf spring.
- 21. The razor assembly of claim 20 further including indicator means for indicating the amount of fluid shaving aid remaining in the reservoir.
- 22. The razor assembly of claim 21 wherein the indicator means includes a member fixedly attached to the piston assembly and slidably disposed within an opening in the yoke.
