Abstract
Abstract A plurality of individual thin-walled generally disk-shaped blades are resiliently mounted in an elastomeric pad. The elastomeric pad, with its individually mounted blades, is disposed over a flexible sponge-like member. The shaving device is flexible and maintains maximum skin contact regardless of the contour of the area being shaved by providing that each individual blade is independently movable with respect to the other blades.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
194 words
A multidirectional shaving device comprising: a plurality of razor blades, each of said razor blades having a generally tubular upstanding wall of a predetermined height and defining a central aperture, said wall having an upper and lower end, an integrally formed inwardly facing flange on said upper end, said inwardly facing flange having a sharpened cutting edge, and an integrally formed outwardly facing flange on said lower end; a body including an elastomeric member having a face surface and a bottom surface, said elastomeric member including a plurality of apertures, each of said razor blades being disposed in one of said apertures, said bottom surface of said elastomeric member including bearing surfaces disposed over and cooperating with said outwardly facing flanges of said razor blades; and a flexible sponge-like member disposed under said bottom surface of said elastomeric member and under said lower ends of said razor blades, said sponge-like member including a plurality of rinse holes, each of said rinse holes being aligned with said central aperture of one of said razor blades, whereby each of said razor blades is capable of retracting vertically and angularly substantially independently of said other razor blades.
Claim 2
Dependent Claim
194 words
A multidirectional shaving device comprising: a plurality of razor blades, each of said razor blades having a generally tubular upstanding wall of a predetermined height and defining a central aperture, said wall having an upper and lower end, an integrally formed inwardly facing flange on said upper end, said inwardly facing flange having a sharpened cutting edge, and an integrally formed outwardly facing flange on said lower end; a body including an elastomeric member having a face surface and a bottom surface, said elastomeric member including a plurality of apertures, each of said razor blades being disposed in one of said apertures, said bottom surface of said elastomeric member including bearing surfaces disposed over and cooperating with said outwardly facing flanges of said razor blades; and a flexible sponge-like member disposed under said bottom surface of said elastomeric member and under said lower ends of said razor blades, said sponge-like member including a plurality of rinse holes, each of said rinse holes being aligned with said central aperture of one of said razor blades, whereby each of said razor blades is capable of retracting vertically and angularly substantially independently of said other razor blades.
