Abstract

An interdental cleaner has a rod-shaped support which is made of plastic and which, at a support rear end region, has a grip part. A support opposite front end region has a flocking with flock fibers made of plastic. The rod-shaped support is provided, in the support front end region, with a sleeve-shaped cover made of a flexible plastic. The flocking is arranged on the cover.

Claims (29)

1. An interdental cleaner comprising:

a rod-shaped support comprised of plastic with a rear end region having a grip part and an opposite front end region;

a sleeve cover; and

a flocking with flock fibers made of plastic, wherein the rod-shaped support is provided, in the front end region, with the sleeve cover made of a flexible plastic, and the flocking is arranged on the cover, wherein the outside of the cover has a plurality of integrally formed fingers protruding radially outward, the fingers being made of the same flexible material as the cover, wherein the sleeve cover is provided with the flocking in a cover region between a cover front end and the fingers.

2. The interdental cleaner as claimed in claim 1 , wherein the cover is covered completely by the flocking.

3. The interdental cleaner as claimed in claim 1 , wherein the cover is covered by the flocking only in a cover front end region.

4. The interdental cleaner as claimed in claim 1 , wherein a region of the cover lying between the fingers is free of the flocking.

5. The interdental cleaner as claimed in claim 1 , wherein the flocking is arranged in a region of the cover lying between the fingers.

6. The interdental cleaner as claimed in claim 1 , wherein the support is made of a dimensionally stable plastic comprised of polypropylene or polyamide.

7. The interdental cleaner as claimed in claim 1 , wherein the plastic material of the support is fiber-reinforced.

8. The interdental cleaner as claimed in claim 1 , wherein the cover is predominantly comprised of a thermoplastic elastomer, of a thermoplastic polyurethane or of silicone.

9. The interdental cleaner as claimed in claim 1 , wherein the flocking comprises an adhesive layer on which the flock fibers are held.

10. The interdental cleaner as claimed in claim 1 , wherein the flock fibers are made of polyamide, polypropylene, polybutylene terephthalate, viscose, acryl, or polyester.

11. The interdental cleaner as claimed in claim 1 , wherein a length of the flock fibers lies in a range of 0.2 mm to 2.0 mm.

12. The interdental cleaner as claimed in claim 1 , wherein the flock fibers have a fineness in a range of 0.09 tex to 2.2 tex, wherein 1 tex=1 g per 1000 m length.

13. The interdental cleaner as claimed in claim 1 , wherein the support has a circular, polygonal, oval or triangular cross section.

14. The interdental cleaner as claimed in claim 1 , wherein an outer contour of the cover follows an outer contour of the support.

15. The interdental cleaner as claimed in claim 1 , wherein the cover has a triangular outer contour and the support has a circular, polygonal or oval cross section, such that tapering corner regions of the cover are formed.

16. The interdental cleaner as claimed in claim 1 , wherein each and every portion of the flocking is located at a spaced location from the support.

17. An interdental cleaner comprising:

a rod-shaped support comprised of plastic with a rear end region having a grip part and an opposite front end region;

a sleeve cover; and

a flocking with flock fibers made of plastic, wherein the rod-shaped support is provided, in the front end region, with the sleeve cover made of a flexible plastic, and the flocking is arranged on the cover, the flocking being located at a spaced location from the rod-shaped support, wherein the outside of the cover has a plurality of integrally formed fingers protruding radially outward, the fingers being made of the same flexible material as the cover, wherein the cover is provided with the flocking in a cover region between a cover front end and the fingers.

18. The interdental cleaner as claimed in claim 17 , wherein each of the plurality of integrally formed fingers extend to a radial position beyond a radial position of each of the flock fibers with respect to a longitudinal axis of the sleeve cover.

19. An interdental cleaner comprising:

a rod-shaped support comprised of plastic with a rear end region having a grip part and an opposite front end region;

a sleeve cover; and

a flocking with flock fibers made of plastic, wherein the rod-shaped support is provided, in the front end region, with the sleeve cover made of a flexible plastic, and the flocking is arranged on the cover, each and every portion of the flock fibers being arranged at a position outside of the sleeve cover, wherein the outside of the cover has a plurality of integrally formed fingers protruding radially outward, the fingers being made of the same flexible material as the cover, wherein the cover is provided with the flocking in a cover region between a cover front end and the fingers.

20. The interdental cleaner as claimed in claim 19 , wherein each portion of each of the flock fibers is free of contact with the rod-shaped support.
