Abstract

Abstract The invention provides the combination of a razor blade 10 and holder 12 for the razor blade, wherein the cutting edges of the blade are constituted by the periphery of a number of holes 10b in the blade, and the holder is provided with means 13 by which the blade can be picked up from a razor blade dispenser 16, the holder maintaining the picked-up blade in an arched condition for shaving. The dispenser may have at least one compartment in which an unused blade 10 can be retained in an arched condition whereby parallel sides of the blade can be engaged by the holder 12 which increases the flexure of the blade to release it from the compartment.

Claim 1
Independent Claim 193 words
The combination of a razor blade and holder for the razor blade, wherein said blade comprises a generally rectangular foil having a plurality of holes extending therethrough, the peripheries of said holes forming cutting edges in the blade and the holder is provided with means by which the blade can be picked up from a razor blade dispenser, said means including a blade receiving track formed by a spaced pair of inwardly directed flanges adapted to engage opposite sides of the blade, the spacing between said flanges being less than the distance between said sides when said blade is unrestrained, whereby said blade is maintained in a convexly flexed condition for shaving, wherein the holder has means for covering each end of said track when a blade is held in said track, whereby each end of the blade is shielded from engagement with the skin of the user, and wherein the means on the holder for picking up a blade is movable relative to the handle of the holder between a blade pick-up position at which the ends of said track are uncovered and a shaving position at which said ends are covered.
