Abstract

The invention relates to a toothbrush with a handle (2) and a headpiece (1), on which brush filaments (3) and at least one soft elastic cleaning element (6) are arranged. According to the invention, the at least one soft elastic cleaning element (6) is arranged on a support element (5), made from a hard material, connected to the headpiece (1). The invention further relates to a method for production of such a toothbrush.

Claims (23)

1. A toothbrush having a handle (2) and a head part (1) with bristle filaments (3) and a flexible structure (6, 6', 22), wherein the flexible structure (6, 6', 22) is arranged on a carrier element (5) which consists of a hard material and is connected to the head part (1) , wherein a non-releasable connection is provided between the carrier element (5) and the head part (1).
2. The toothbrush as claimed in claim 1, wherein the flexible structure comprises at least one flexible cleaning element.
3. The toothbrush as claimed in claim 1 or 2, wherein the carrier element (5) consists of the same material as the head part (1).
4. The toothbrush as claimed in claim 1, 2 or 3, wherein the non-releasable connection provided between the carrier element (5) and head part (1) is produced by clamping, snap-fitting, riveting, adhesive bonding, welding, ultrasonic welding or the supply of heat.
5. The toothbrush as claimed in one of the preceding claims, wherein the flexible structure (6, 6', 22) and the carrier element (5) are produced by two-component or multi-component injection molding, a non-releasable connection preferably being provided between the flexible structure (6, 6', 22) and the carrier element (5).
6. The toothbrush as claimed in one of the preceding claims, wherein the material of the carrier element (5) is polypropylene (PP), styrene-acrylonitrile (SAN), acrylonitrile-butadiene-styrene (ABS), Isoplast® or polyester (PET).
7. The toothbrush as claimed in one of the preceding claims, wherein the bristle filaments (3) are arranged on the carrier element (5).
8. The toothbrush as claimed in one of the preceding claims, characterized in that the bristle filaments (3) are anchored on the flexible structure (6'').
9. The toothbrush as claimed in one of claims 1-6, wherein the bristle filaments (3) are connected to a bristle plate (18) or directly to the head part (1) .
10. The toothbrush as claimed in one of the preceding claims, wherein the bristle filaments (3) are guided through cutouts in the carrier plate (5) and/or in the flexible structure (6'') and, for fastening purposes, are welded or adhesively bonded by way of their rear ends (3a), which in the application case are directed toward the head part (1).
11. The toothbrush as claimed in claim 10, wherein the carrier plate (5) is inserted into a cutout (13) in the head part (1) and connected in a non-releasable manner to the head part (1).
12. The toothbrush as claimed in one of the preceding claims, wherein the flexible structure (6, 6', 22) consists of natural or synthetic rubber, preferably of a thermoplastic elastomer, which preferably has a Shore A hardness of less than 90, particularly preferably of less than 50.
13. The toothbrush as claimed in one of the preceding claims, wherein connecting locations between the head part (1) and the carrier element (5) are covered by flexible material (22).
14. The toothbrush as claimed in one of the preceding claims, wherein the head part (1) has a cutout (13), in which the carrier element (5) is inserted such that it can be moved within the cutout (13).
15. A process for producing a toothbrush as claimed in one of the preceding claims, at least one flexible cleaning element (6) being fastened on a carrier element (5) which consists of a hard material and is connected to the head part (1) of the toothbrush, and wherein the carrier element (5) and the head part (1) are connected to one another in a non-releasable manner.
16. The process as claimed in claim 15, wherein the carrier element (5) and the head part (1) are connected to one another in a non-releasable manner by clamping, snap-fitting, riveting, adhesive bonding, welding, ultrasonic welding or the supply of heat.
17. The process as claimed in claim 15 or 16, wherein the bristle filaments (3) are fastened on the head part (1) or a bristle plate (18) and are cut and/or rounded and/or prepared for use in some other way before the carrier element (5) is fastened.
18. The process as claimed in one of claims 15-17, wherein the flexible structure (6, 6', 22) and the carrier element (5) are produced by two-component injection molding and then connected to the head part (1), a non-releasable connection preferably being produced between the flexible structure (6, 6', 22) and the carrier element (5).
19. The process as claimed in one of claims 15-18, wherein the carrier element (5) is provided with the flexible structure (6, 6' , 22) , the head part (1) is provided with conventional clusters of bristles (3) before the carrier element (5) is fitted, the clusters of bristles (3) are machined and then the carrier element (5) is connected to the head part (1).
20. The process as claimed in one of claims 15-19, wherein the bristle filaments (3) are guided through cutouts in the carrier plate and/or in the flexible structure and, for fastening on the carrier plate and/or the flexible structure, are welded or adhesively bonded by way of their rear ends, which in the application case are directed toward the brush head.
21. The process as claimed in claim 20, wherein, following the bristle-covering operation and the production of the flexible structure, the carrier plate is inserted into a cutout in the brush head and connected in a non-releasable manner to the brush head by ultrasonic welding.
22. The toothbrush as claimed in claim 10, wherein the carrier plate is provided with bristles (3) by an anchor-free-tufting method.
23. The process as claimed in claim 20 or 21, wherein the carrier plate is provided with bristles (3) by an anchor-free-tufting method.
