Razor comprising a three dimensional, microstructured abrasion material
A wet shaving razor comprising a handle having a proximate and distal end, a razor cartridge mounted at the proximate end of the handle. The cartridge further includes 1) a housing having a front wall, a rear wall, and opposing side walls joining said front and rear walls; 2) a plurality of razor blades, each blade having a sharpened cutting edge and wherein said blades are disposed in a parallel arrangement extending between said side walls; and 3) an abrasion material comprising a plurality of geometric, three-dimensional, microstructures wherein said material is disposed adjacent to said front wall and forward of said blades.
1. A wet shaving razor comprising:
a. a handle having a proximate and distal end;
b. a razor cartridge mounted at the proximate end of said handle, said cartridge further comprising
1) a housing having a front wall, a rear wall, and opposing side walls joining said front and rear walls;
2) a plurality of razor blades, each blade having a sharpened cutting edge and wherein said blades are disposed in a parallel arrangement extending between said side walls; and
3) an abrasion material comprising a plurality of geometric, three-dimensional, microstructures formed as a sheet wherein said abrasion material is disposed adjacent to said front wall and forward of said blades, said abrasion material comprises a base substrate and a coating which conforms to the plurality of microstructures, said base substrate comprising a dissolvable material.
2. The wet shaving razor of claim 1 wherein said coating is selected from the group consisting of aluminum, nickel, chromium, water- or other solvent based ink or paint and combinations thereof.
3. The wet shaving razor of claim 1 wherein said microstructures comprise polyhedrons selected from the group consisting of pyramids, tetrahedrons, pentahedrons, hexahedrons, septahedrons, octahedrons, and combinations thereof.
4. The wet shaving razor of claim 1 wherein said abrasion material comprises apertures.
5. The wet shaving razor of claim 4 wherein a conditioning agent is expressed through said abrasion material via said apertures.
6. The wet shaving razor of claim of claim 5 wherein said conditioning agent is selected from the group consisting of shaving gel, fragrance, essential oils, vitamins, and combinations thereof.
7. The wet shaving razor of claim 1 wherein said microstructures have an average base surface length of less than about 500 μm.
8. The wet shaving razor of claim 1 wherein said microstructures have an average height of less than about 500 μm.
9. The wet shaving razor of claim 1 wherein said microstructures are arranged in rows and/or columns.
10. The wet shaving razor of claim 1 wherein said abrasion material is secured to said cartridge by adhesive.
11. The wet shaving razor of claim 1 wherein said abrasion material is joined to said cartridge by an attachment mechanism selected from the group consisting of adhesive attachment, injection molding, ultrasonic bonding, insert molding, over-molding, and combinations thereof.
