US Classification:

30 41, 30 3405, 30 50

Abstract:

The present invention is directed to a skin engaging member in the form of a narrow elongated strip of dimensions suitable for placement on a razor cartridge. The skin engaging member includes a first uppermost erodible layer, a second erodible layer positioned below the first layer and a third erodible layer positioned below the second layer. The first layer has a first color and a first thickness dimension. The second layer has a second color different from said the color and a second thickness dimension that is less than the first thickness dimension. The third layer has a third color different from the first color and the second layer and has a third thickness dimension.

Abstract:

The present invention is directed to a skin engaging member in the form of a narrow elongated strip of dimensions suitable for placement on a razor cartridge. The skin engaging member includes a first uppermost erodible layer, a second erodible layer positioned below the first layer and a third erodible layer positioned below the second layer. The first layer has a first color and includes a lubricious water-soluble polymer. The second layer has a second color different from said the color and includes a greater amount of lubricous water-soluble polymer, in percent by weight, than the first layer. The third layer has a third color different from the first color and the second layer and has a third thickness dimension.

US Classification:

Abstract:

The present invention is directed to a razor cartridge including a guard, a cap and a plurality of blades each with sharpened edges located between the guard and the cap. The cap includes a cap edge positioned nearest the blades and an erodible skin engaging member. A cap blade is positioned nearest the cap and an adjacent blade is positioned immediately adjacent to the cap blade and between the cap blade and the guard. The skin engaging member includes at least one upper layer and a base layer positioned below the upper layer. The upper layer erodes during shaving exposing the upper surface of the base layer which is positioned relative to the cap edge such that when the upper layer has eroded the cap blade edge has a final exposure defined by the adjacent blade edge, the cap edge and the upper surface of the base layer.
