Definitions

  • the present invention relates to a plastic bristle for toothbrushes and a toothbrush equipped with such bristles.
  • the object of this invention is to create a plastic bristle which, compared to a conventional bristle, which generally consists of a relatively coarse monofilament, has a better and gentler cleaning action.
  • a toothbrush equipped with such bristles forms the subject of claim 6.
  • the filaments By protruding the filaments over the sheath, a fibrous structure is achieved at the bristle ends, which ensures gentle cleaning of the tooth surface, because the filament ends can penetrate into the finest grooves and depressions on the tooth surface and into the interdental spaces. Damage to the gums is avoided. If the filaments differ optically from the bristle sheath, for example as a result of different colors, not only a special aesthetic effect is achieved, but also a clearly visible indication of the state of use of the toothbrush. The degree of wear of the bristles is so easy to determine.
  • the thickness of the bristles is selected so that they are sufficiently flexible with sufficient rigidity and stability and have the desired fineness.
  • the core of the bristles advantageously consists of at least 2 filaments and preferably 20-60 filaments, which results in a particularly effective and gentle cleaning effect.
  • 1 is a side view of a toothbrush
  • Fig. 4 is a section along the line AA in Fig. 3, and Fig. 5 partially in section, the free end of a single bristle during the tooth cleaning process.
  • the toothbrush 1 shown in FIG. 1 has a handle 2 in a known manner and a bristle carrier 3 integral therewith. Bristle bundles 4 are inserted into this bristle carrier 3. As can be seen from FIG. 2, each bristle bundle 4 consists of a large number of bristles 5.
  • Each bristle has a core 6 which is formed by a number of preferably parallel filaments 7 made of plastic. This core 6 is surrounded by a jacket 8, which is formed by a matrix 9 made of plastic, in which the filaments 7 are embedded, and preferably free of voids.
  • the filaments 7 and the matrix 9 can consist of the same plastic, preferably of a polyamide.
  • the filaments 7 protrude beyond the jacket 8, as can be seen from FIGS. 3 and 5.
  • This protrusion of the filament ends arises from the fact that the bristles 5 are machined at their free end 5a by a suitable rounding process, as a result of which the sheath 8 is removed mechanically. The filament ends are not chafed away.
  • the core 6 consists of at least 2 filaments, but preferably 20-60 filaments 7.
  • the filaments 7 have a thickness (diameter d) of 0.01-0.08 mm.
  • the thickness (diameter D) of the bristles 5 is 0.1-0.3 mm, preferably 0.15-0.25 mm.
  • the sheath 8 and the filaments 7 should differ optically from one another. This is achieved in a particularly simple manner in that the filaments 7 have a different color than the sheath 8. This measure achieves a special aesthetic effect and creates the possibility of displaying the state of use of the toothbrush. Because of the different coloring of the jacket 8 and the protruding filament ends 7a, it can be easily recognized when the free bristle end 5a is worn out, ie the protruding filament ends 7a have been chafed away.
  • FIG. 5 shows the advantages that result from the special design of the bristles 5 without further ado.
  • the ends 7a of the fine filaments projecting beyond the jacket 8 form a fibrous structure, which makes it possible to penetrate into the finest grooves and depressions in the surface 10a of a tooth 10 and thus achieve a gentle but very effective cleaning.
  • the gums are spared.
  • the bristles 5 have sufficient rigidity on the one hand and sufficient flexibility on the other hand so that the desired cleaning effect can be achieved.

Abstract

Le poil (5) en plastique comprend un coeur (6) constitué de filaments (7) en plastique parallèles liés les uns aux autres, ainsi qu'un manchon (8) en plastique entourant ledit coeur (6). Au niveau de l'extrémité active (5a) du poil (5), les filaments sortent du manchon (8) et en dépassent. Pour cela, on arrondit les poils (5) à leur extrémité (5a), ce qui en même temps raccourcit mécaniquement le manchon (8).
