Abstract
In a microprismatic shaving element for abrasively removing hair, a substrate defines a plurality contiguous raised portions projecting outwardly therefrom. Each of the raised portions defines at least one hair engaging surface and is located on the substrate in an array that defines an abrasive surface. During a shaving operation as the abrasive surface is drawn over the skin of the user, each of the raised portions successively abrades hair extending from extending from said user's skin leaving the ends of the hair frayed after completion of the shaving operation thereby achieving the feel of a smooth shave.
Claims15
A microprismatic shaving element for abrasively removing hair, comprising:
- a substrate;
- a plurality of contiguous raised portions projecting outwardly from said substrate, each defining at least one hair engaging surface;
- said raised portions being located on said substrate in an array, that defines an abrasive surface;
- and wherein
- during a shaving operation, as said abrasive surface is drawn over the skin of a user, each of said raised portions successively abrades hair extending from said user's skin, leaving the ends of said hair frayed after completion of said shaving operation, thereby achieving the feel of a smooth shave.
A disposable shaving cartridge comprising:
- a housing having a portion adapted to releasably mate with a razor handle;
- an abrasive strip coupled to said housing and defining an outwardly facing surface having a plurality of contiguous raised portions projecting outwardly therefrom;
- each of said contiguous raised portions defining at least one hair engaging surface said contiguous raised portions collectively defining an abrasive surface;
- and whereby
- as said shaving cartridge is drawn across the skin of a user during a shaving operation, said abrasive surface contacts any hair protruding from the user's skin so that each of said microprismatic elements abrades said hair removing a portion thereof and leaving a frayed end thereby yielding the feel of a close shave.
A shaving implement comprising:
- a handle;
- a shaving head coupled to said handle and including;
- an abrasive strip coupled to said shaving head and defining an outwardly facing surface having a plurality of contiguous raised portions projecting therefrom;
- each of said contiguous raised portions defining at least one hair engaging surface, said contiguous raised portions collectively defining an abrasive surface;
- and whereby
- as said abrasive strip is drawn across the skin of a user during a shaving operation, said abrasive surface contacts any hair protruding from the user's skin so that each of said microprismatic elements abrades said hair removing a portion thereof and leaving a frayed end thereby yielding the feel of a close shave.
