Abstract
Official abstract text for this publication.
A razor blade assembly ( 12 ) device includes one or more razor blades ( 22 ) configured to shave a skin surface when drawn across the skin surface in a forward direction. A friction surface ( 20 ) is situated in front of the razor blades. The friction surface includes an array of raised separated projections ( 24 ). Distal ends of the raised projections terminate in substantially flat faces. total area of the flat faces is greater than 10% of the area of the friction surface
First claim
Opening claim text (preview).
1 . A razor blade assembly device comprising: one or a plurality of razor blades configured to shave a skin surface when drawn across the skin surface in a forward direction; and a friction surface situated in front of said one or a plurality of razor blades, the friction surface including an array of raised separated projections, distal ends of the raised projections terminating in substantially flat faces, wherein a total area of the flat faces is greater than 10% of the area of the friction surface. 2 . The device of claim 1 , wherein each of the raised projections is made of an elastomer. 3 . The device of claim 1 , wherein the total area of the flat faces is greater than 20% of the area of the friction surface. 4 . The device of claim 1 , wherein the total area of the flat faces is less than 90% of the area of the friction surface. 5 . The device of claim 1 , wherein an aspect ratio of each of the raised projections is less than 2. 6 . The device of claim 5 , wherein the aspect ratio is less than 1. 7 . The device of claim 1 , wherein adjacent projections of the array of raised projections are separated by channels. 8 . The device of claim 7 , wherein a majority of the channels are oriented such that a long dimension of each channel of the majority is oriented substantially parallel to the forward direction or at an oblique angle to the forward direction. 9 . The device of claim 7 , wherein each of the channels has a substantially rectangular cross-sectional profile. 10 . The device of claim 7 , wherein each of the channels has a substantially V-shaped cross-sectional profile. 11 . The device of claim 7 , wherein each of the channels has a substantially inverted arch cross-sectional profile. 12 . The device of claim 1 , wherein each of the faces has a substantially hexagonal shape. 13 . The device of claim 1 , wherein each of the faces has a substantially parallelogram shape. 14 . The device of claim 1 , wherein each of the faces has a shape that is substantially in the form of a chevron. 15 . The device of claim 1 , wherein each of the faces has shape with a curved side. 16 . The device of claim 1 , wherein each of the faces has a shape that is substantially in the form of an elongated symmetric teardrop. 17 . The device of claim 1 , configured to attach to a handle. 18 . The device of claim 1 , further comprising a lubricant dispenser.
