ROTARY SHAVER, MANUFACTURING METHOD FOR OUTER BLADE THEREOF, AND OUTER BLADE

WIPO Patent Application WO/2013/021514

A1

A rotary shaver, which is equipped with an outer blade in which multiple beard-accepting holes are formed in the shaving surfaces that form ring-shaped protrusions and an inner blade that rotates in contact with ring-shaped shaving grooves of the lower surface of the outer blade, and which cuts hair that enters the beard-accepting holes of the outer blade using the inner blade. The outer blade is formed into the disc-shaped outer blade shape by machining beard-accepting holes in a metal sheet and drawing the metal sheet. Deep drawing of the metal sheet is not always required, the use of special drawing molds, cutting, or difficult machining methods such as ECM or electric discharge machining is not necessary, and productivity can be significantly improved. The machined shape of the beard-accepting holes is not limited to straight lines, making it possible to increase the degree of freedom in designing the shaving surface. The rotary shaver is also suitable for reducing the weight thereof.
