Definitions

  • the invention relates to a razor head arranged at the front end of a handle, in particular a razor blade unit, of a wet razor, in which a single or double razor blade is arranged in a plastic body having a front guide bar and a rear cover cap, the cover cap being provided with a sliding strip.
  • a razor head which carries the single or double razor blade, is arranged at the front end of a handle.
  • the front shaver head can be integrally formed with the handle in the form of a molded plastic part. If the razor head is designed separately from the handle and can be exchangeably attached to it by means of a corresponding mechanism, one speaks of a so-called razor blade unit in which a single or double razor blade is embedded in a plastic housing so that it cannot be detached.
  • a razor head in the form of such a razor blade unit is known in various embodiments.
  • a plastic body is provided in which a single or double razor blade is embedded non-detachably.
  • the plastic body has a front guide strip in the area of the cutting edge (s) of the razor blade (s), while a cover cap is provided in the rear area.
  • This can be provided with a friction-reducing sliding strip, which is always smooth, ie flat, in the known embodiments. With this sliding strip which reduces the friction between the razor head and the skin, an improved shave is possible, but it is not particularly effective at the end of the razor head.
  • the object of the invention is to create a razor head, in particular a razor blade unit, of a wet razor with an improved sliding strip and thus with an improved sliding behavior.
  • the invention proposes that the sliding strip is convexly curved.
  • the sliding strip thus bent over the cover cap, in particular in the form of a coated film, which is convex in the edges of the cover cap and whose line of curvature is the same extending parallel to the cutting edge (s) of the razor blade (s) can be created and applied by means of a special hot molding process.
  • the particular advantage is that the sliding strip is also more effective at the end of the razor head. Since the skin is stretched and pressed in during shaving, a bulge forms at the end of the shaver head.
  • the glide strip shaped in the radius glides optimally in this area and thus increases the gentle shave.
  • the convexly curved sliding strip according to the invention in the form of a convexly curved film represents a particularly inexpensive embodiment of a razor head provided with a sliding strip.
  • the glide strip has a front, essentially flat or slightly convexly curved glide strip leg and an angled rear, also essentially flat or slightly convexly curved glide strip leg, which are connected to one another by an arc. This is an optimal form of the glide strip, with which an extremely gentle shave is possible.
  • the cover cap has a flat recess on the top side in which the sliding strip is received. Due to the inclusion of the sliding strip inside the cover cap, the latter does not protrude above the latter, but adapts fully to the surface formation of the cover cap.
  • the sliding strip is a film which is provided with a lubricious coating.
  • a coated film has the advantage that it can be very easily applied to the cover cap in the convexly curved shape.
  • a razor head in the form of a so-called razor blade unit for a wet shaver which can be attached to the front end of a handle, not shown, consists of a plastic body 1 in which two razor blades 2 are arranged, the cutting edges 3 of which run parallel and offset one behind the other.
  • the plastic body 1 consists of a base part 4 with the razor blades 2 and an upper part 5 placed on this base part 4.
  • the base part 4 of the plastic body 1 initially has feed-through slots 6 on the inside.
  • the base part 4 defines a platform 7 for the razor blades 2.
  • a spacer 8 is sandwiched between the two razor blades 2, the two razor blades 2 being firmly connected to this spacer 8. These thus form a razor blade / spacer / razor blade unit 9. This is placed on the platform 7 of the base part 4 from above, the spacer 8 projecting laterally for this purpose and being received in lateral recesses 10 of the base part 4.
  • the unit 9 is held by means of a zigzag wire 11 which extends over the top 12 of the unit 9 and thus the base part 4 of the plastic body 1 is guided.
  • the base part 4 has, on the front 13 in the lower region, downward-shaped molded projections 14 which are designed as elongated strips.
  • the width of these projections 14 in the direction of the cutting edges 3 of the razor blades 2 essentially corresponds to the distance between the projections 14.
  • the projections 14 In the front region, the projections 14 have a raised extension 15.
  • the rear side 16 of the base part 4 has projections 14 ′ which are directed towards the rear. These projections 14 ′ fill the gaps between the projections 14 on the front 13. Corresponding to the projections 14, the projections 14 ' also have projections 15' which, however, are directed downwards. Finally, fastening projections 17 are integrally formed on the rear side 16 of the base part 4.
  • the wire 11 is first fastened with its one end to a fastening projection 17. Then it is guided via the unit 9 to the front to the projection 14 and around it, in order to subsequently run back through 180 ° over the unit 9, where the wire 11 is guided around the projection 14 ′ there.
  • the wire 11 is thus guided in succession around the projections 14 and 14 ′ in order to finally be attached at its other end to the attachment projection 17 on the other side of the base part 4.
  • the sections of the wire 11 run parallel to one another in the region of the upper side 12 and at substantially constant intervals.
  • the wire 11 on the one hand holds the unit 9 firmly on the platform 7 of the base part 4 and on the other hand prevents skin injuries.
  • the upper part 5 is a one-piece plastic component and initially has a front guide bar 18. This extends parallel to the cutting edges 3 of the razor blades 2 and has a step-like longitudinal profile 19.
  • a cover cap 20 is provided in the rear area.
  • This has a sliding strip 21 on the upper side. This is convexly curved and initially has a first glide strip leg 22 and a second glide strip leg 22 ′, which is angled to an acute angle, and which are connected to one another by an arc 23.
  • the angle between the sliding strip legs 22, 22 ' can also be rectangular or obtuse.
  • the two sliding strip legs 22, 22 ' are essentially flat or slightly convex. The production of such a sliding strip 21 is possible by means of a special hot molding process.
  • this sliding strip 21 is also more effective at the end of the razor blade unit. Since the skin is stretched and pressed in during shaving, a bulge forms at the end of the razor blade unit. The sliding strip 21 shaped in the radius slides better in this area and thus increases the gentle shave.
  • the front guide strip 18 and the rear cover cap 20 are connected to one another by side walls 24. Between these parts there is an opening 25 in the area of the cutting edges 3 of the razor blades 2, as can be seen in particular from the top view according to FIG. 1.
  • Both the inside of the guide bar 18 and the inside of the cover cap 20 have receiving grooves 26 for the wire 11. Underneath the guide bar 18 there are recesses 27 which engage in a corresponding manner with the projections 14 of the base part 4. On the back this shows from the guide bar 18, the cover cap 20 and the side walls 24 formed upper part 5 through openings 28 which correspond to corresponding through openings in the spacer 8.
  • the upper part 5 is plugged onto the base part 4 with the unit 9 fastened by the wire 11 and secured from above, for example by latching or in another way.
  • the wire 11 runs therein.
  • the course of the wire 11 in the area of the top 12 has the advantage that the bottom 29 of the plastic body 1 remains free and corresponding fastening systems can thus be provided.
