Definitions

  • the invention relates to a razor blade unit for a razor, in which a razor blade or two parallel razor blades are embedded in a plastic body, the cutting edges of which are partially provided with a cover.
  • Razor blade units for wet shavers are known in which a single razor blade or a double razor blade is embedded in a plastic body, the cutting edges of the two razor blades being offset from one another in the double razor blade.
  • a disadvantage of these razor blade units is that unevenness in the skin can be detected by the razor blades during the shaving process and can therefore be the cause of skin injuries (skin irritation) which are sometimes not visible.
  • the object of the invention is to improve the shaving properties in the known razor blade unit.
  • the invention proposes that the plastic body, together with the razor blades, be wrapped with a wire with several turns lying next to one another, the individual turns in the region of the contact surface of the razor blade unit against the skin running parallel to and at a distance from one another.
  • a razor blade unit designed according to this technical teaching with a protective wire considerably improves the shaving properties.
  • the wire prevents the formation of a skin fold, so that skin injuries are avoided even in the invisible area.
  • the wire reduces the required shaving resistance because it also reduces the frictional force that occurs in the protective cap of the razor blade unit to approximately 50% of the total frictional force.
  • the wire is preferably made of metal, since metal with skin has a relatively low coefficient of friction, so that the required shaving resistance is reduced to a minimum.
  • the wire has a diameter of less than 0.1 mm, so that the effective shaving surface is only minimally reduced.
  • the invention proposes that the wire be at least partially in grooves formed in the plastic body is led. These guide grooves ensure that the wire runs in the specified turns at all times without it being able to slip laterally, particularly during the shaving process.
  • the razor blade unit for a wet shaver which can be attached to a handle, not shown, consists of a plastic body 1, in which two razor blades 2.2 'are embedded, the cutting edges 3.3' parallel and offset to each other.
  • the plastic body 1 is wrapped together with the razor blades 2.2 'by means of a wire 4.
  • This wire 4 forms helical windings which run at a distance from one another, as can be seen in FIGS. 1 and 2.
  • the turns of the wire 4 run parallel to the shaving direction, while on the one in FIG. 2 shown back of the razor blade unit, the turns run obliquely.
  • the wire 4 is made of metal and preferably has a diameter of less than 0.1 mm.
  • the plastic body 1 is at least partially provided with grooves 5 in which the individual turns of the wire are guided.
