Abstract: A blade cartridge for a shaving razor contains a series of parallel blades and at least two contact segments as part of an electric circuit connected to the blades at spaced intervals to provide an electric current flow through the blades in a manner that provides more efficient heat distribution across the length of the blades. A radiator effect is created wherein heat produced by the contact segments passes between the blades towards the cutting edge of the blades. The combination of the heat produced by the electric current flow through the conductive blades and the heat produced by the contact segments provides a dual heat process that makes it easier to adjust and control the temperature to a desired stable heat temperature. A thin conductive film may be fitted to be in contact with the ends of the blades to insure conductivity throughout the entire length of each blade.

Abstract: In a reciprocating-type electric shaver, an inner blade has an attachment groove which is open downward in a lower end of a side edge. An inner peripheral portion of the attachment groove has an engagement groove which is recessed in an in-plane direction on a wall surface of the side edge and in a longitudinal direction of the inner blade. An inner blade base has a projection at a position corresponding to the attachment groove. The projection can be elastically deformed in the in-plane direction on the wall surface of the side edge and in the longitudinal direction of the inner blade, and is formed so that an engagement claw disposed in a distal end of the projection can enter and engage with the engagement groove. The engagement claw engages with the engagement groove, thereby causing the inner blade to be fixed to the inner blade base.
