Definitions

  • the present invention relates to a brush head for a toothbrush according to the preamble of claim 1.
  • a brush head of this type is in WO-A-96/02165 shown and described.
  • this known brush head are the bristle bundles at the anchoring end directly in the soft elastic material of the Bristle holder anchored. The bundles of bristles are thus melted directly into the rubber-elastic material.
  • anchoring the bristle bundle in the soft elastic material it can happen that when using the brush head due to tensile forces, that act on the bristles or bristle bundles, certain Bristles or bristle bundles from the soft elastic Material to be torn out.
  • the known Brush head is also a thin, curved one Extension part available, made of the same hard Material like the handle is made of and soft elastic material in which the bristle bundle are embedded, surrounded. The extension part has some flexibility to use the To be able to bend toothbrush back.
  • EPC forms are embodiments of Brush heads revealed in those Bristle bundles, which form lateral rows of bristles, at the anchoring end in the soft elastic material of a lateral holding part are embedded.
  • the soft elastic material of these holding parts is in the range each bundle of bristles pulled up into a cuff that surrounds the associated bundle of bristles. The connection between the bristle bundles and the cuff directly by merging.
  • the bristle bundles of the lateral rows of bristles each held in a sleeve-like anchoring part.
  • These anchoring parts are in the soft elastic Material of the side holding part embedded and with each other via a connecting part, the one Continuation of the handle forms and from the same hard material, like the latter, exists firmly together connected.
  • the object of the present invention is now based on a brush head of the type mentioned create that with a more secure anchoring of the Bristle bundle an even better adaptation of the same the shape of the bit to be cleaned and the individual Teeth allowed.
  • the bristle bundles in sleeves or as a holding part serving connecting parts is a good one Anchoring of the bristle bundles ensured.
  • the spaced sleeves or connecting parts are in the soft elastic material of the bristle carrier embedded that the connection between the sleeves or Produces connecting parts. This will Bristle carriers give increased flexibility to what when cleaning the teeth a better adjustment of the Bristle bundle to the tooth and bit shape allows.
  • Fig. 1 is a plan view and in Fig. 2 in section along the line II-II of Fig. 1, a brush head 1 and shown part of the handle 2 of a toothbrush.
  • the Brush head 1 has a bristle holder 3 in which protruding bristle bundles 4, each of which is a There are a large number of bristles that are anchored. At the each end of the bristle bundle is 4 in a sleeve 5 attached.
  • the sleeves 5 with the Bristle bundles 4 are spaced apart and in present embodiment example in rows arranged which are parallel and perpendicular to Extend toothbrush longitudinal axis A.
  • the bristle holder 3 consists of a soft elastic material that is elastically compressible and stretchable, e.g. from a Elastomer.
  • the sleeves 5 are elastic in this Embedded material that on the one hand connects the Manufactures sleeves 5 with each other and the other Bristle holder gives a certain flexibility.
  • FIGS. 3 and 4 are variants of the first Embodiment according to FIGS. 1 and 2 in plan view shown. These are the two variants Bristle bundle 4 not individually in the soft elastic Material of the bristle carrier 3 used, but too Groups 6 summarized.
  • the bristle bundle 4 each Group 6 are used as holding parts Connecting parts 7 connected to each other.
  • everybody Connecting part 7 has holes 7a into which the Bristle bundles 4 are used.
  • the connecting parts 7 are wholly or partly made of flexible material the bristle carrier 3 surrounded.
  • the Connecting parts 7 transversely, preferably approximately at right angles to the toothbrush longitudinal axis A.
  • Each group 6 thus exists from a number of side by side in the connecting part 7 arranged bristle bundles 4.
  • the configuration for the variant is according to 4 more versatile, since the connecting parts 7 have different shape.
  • FIG. 4 it is also possible in the same bristle carrier 3 both individually bristle bundles 4 anchored in sleeves 5 as well as groups Arrange 6 bundled bristle bundles 4.
