Definitions

  • the present invention relates to a bristle Plastic for toothbrushes and one with such bristles stocked toothbrush.
  • FR-A-2 539 283 is a core and a cladding Single bristles made of plastic known.
  • the one-piece core is comparatively stiff and is completely enclosed by the jacket. During the In use, the coat wears out, which over time leads to the core is exposed.
  • This invention is based on the object to create plastic bristles that are compared to one conventional bristle, which usually consists of one relatively coarse monofilament, a better one and more gentle cleaning effect.
  • a toothbrush equipped with such bristles forms Subject matter of claim 7.
  • each bristle consists of a variety of thin filaments, there is a better Cleaning effect than with a monofilament existing plastic bristle.
  • the filaments differ optically from Bristle coat, e.g. due to different colors, so not only will it have a special aesthetic effect achieved, but also a clearly visible display for the Condition of use of the toothbrush created.
  • the measure of Wear of the bristles is so easy determine.
  • the thickness of the bristles is chosen so that they are sufficient rigidity and stability sufficiently flexible are and have the desired fineness.
  • the core of the bristles advantageously consists of at least 2 filaments and preferably from 20-60 Filaments, which is a particularly effective and gentle cleaning effect.
  • the toothbrush 1 shown in Fig. 1 has known ones Way a handle 2 and one piece with this Bristle holder 3.
  • this bristle carrier 3 are Bristle bundle 4 used.
  • Each bristle has a core 6 by a number from preferably mutually parallel filaments 7 Plastic is formed.
  • This core 6 is from one Sheath 8 surrounded by a matrix 9 made of plastic is formed, in which the filaments 7 are embedded, preferably void-free.
  • the filaments 7 and the matrix 9 can be made of the same plastic, preferably consist of a polyamide.
  • At the free end 5a of the bristle 5 are the filaments 7 above the jacket 8, like that 3 and 5 emerges. This supremacy of Filament ends arises because the bristles 5 on its free end 5a by a suitable rounding method are processed, whereby the jacket 8 mechanically is removed. The filament ends are not chafed away.
  • the core 6 consists of at least 2 filaments, but preferably from 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 are said to be optical differentiate from each other. This is going to be special easily achieved in that the filaments 7 a have a different color than the jacket 8. With this measure a special aesthetic effect is achieved and the Possibility to display the state of use of the Toothbrush created. Because of the different coloring of sheath 8 and the protruding filament ends 7a easily recognize when the free bristle end 5a is worn out, i.e. the protruding filament ends 7a are chafed away.
  • bristles 5 shows the advantages without further ado the special design of the bristles 5 surrender.
  • the projecting over the jacket 8 ends 7a fine filaments form a fibrous structure, which makes it is possible in the finest grooves and indentations penetrate the surface 10a of a tooth 10 and so a gentle, but very effective cleaning achieve. In addition, the gums are spared.
  • bristles 5 have sufficient rigidity and on the other hand sufficient flexibility so that the desired cleaning effect can be achieved.
