Definitions

  • the present invention relates to a brush head of a brush, in particular a toothbrush, with a base support formed of a soft elastic material, in which a plurality of bristle bundle carrying and separate connecting elements are embedded, each comprising individual bristle bundles fastening side.
  • Such a brush head is known from EP-0 923 326 B1.
  • individual bundles of bristles surrounding individual bundles of bristles are embedded in the base support formed from the soft-elastic material, which completely surround the bristle bundles at the end.
  • the connecting elements are to serve the secure connection of the bundles of bristles in the base carrier, as shown in EP-0 923 326 in a known from WO-A-96/02165 brush head, in which the bristle bundles are embedded directly in the soft elastic material, a has given insufficient pull-out strength.
  • EP-0 923 326 B1 proposes anchoring the fastening-side ends of the bristle bundles in the sleeves. Under anchoring is regularly understood in the manufacture of toothbrushes, the attachment of the bristle bundles by an introduced into the brush head metal clip, the so-called anchor. This becomes halfway along with the filaments forming the bristle bundle in receiving openings, i. the openings of the sleeves, introduced. The bristle bundles are placed around the clip and guided by the wall parallel to each other.
  • the sleeves provided for anchoring the bundles of bristles in EP-0 923 326 B1 must be closed on the bottom side for insertion of the armature and have a certain material thickness with regard to secure abutment of the metallic armatures.
  • the present invention is based on the problem to improve a brush head of the type mentioned while avoiding the above problems.
  • the present invention addresses the problem of specifying a brush head of the type mentioned, which allows a small height and an arrangement of bristle bundles in the smallest space.
  • the present invention proposes a brush head having the features of claim 1. This differs from the generic brush head in that the connecting element is formed by a support ring, which is penetrated by the bristle bundle, and that the bristle bundle is secured by positive engagement between the mounting side end of the bristle bundle and the front end of the support ring against extension of the support ring ,
  • each with a continuous Opening provided cylindrical member to be understood.
  • a component can be understood which has a greater axial than radial extent. In view of the lowest possible height but plate-shaped support rings are to be preferred, which are optionally completely embedded in the soft elastic material.
  • the brush head can be formed with a low height.
  • the connecting elements act as a stop when the pull-out force acts on the bundles of bristles, the connecting elements can be formed with a smaller wall thickness, so that the individual bristle bundles can be set closer to one another in the brush head according to the invention.
  • the brush head according to the invention has the advantages known from the prior art, namely that the bristle bundles held in the individual support rings can be pivoted relatively freely relative to one another due to the soft elastic properties of the base support. This free pivoting results from the fact that the connecting elements are embedded separately from each other in the base support.
  • the brush head according to the invention offers the possibility of combining a low structural height with a high degree of flexibility of the individual bristle bundles.
  • EP 0 159 940 and FR 2 570 940 which is based on the same inventor, merely disclose the elastic mounting of the bristle bundles under compressive stress along the longitudinal axis of individual bristle bundles.
  • FR 2 570 940 on the back of a uniform, several channels for each bundle of bristles having a retaining pad deposited a gel pad, which is clamped between the support plate and a rear wall of the brush head.
  • the individual bundles of bristles may sink along the axis of the channels under excessive axial stress in the direction of the brush head.
  • the holding plate with the interposition of an elastic membrane in one Brush head clamped. Between the membrane and the rear wall of the brush head there is a free space in which the individual bristle bundles are compressed.
  • the brush head in both embodiments up to the interior reaching ventilation ducts, which should be compensated in the interior of the brush head during compression of the gel pad or deformation of the membrane resulting volume change.
  • these vent channels prevent adequate training of the previously known toothbrush, taking into account the hygienic requirements.
  • the brush head consists of a base support 1, which is formed of a soft elastic material, in particular a thermoplastic elastomer (TPE).
  • TPE thermoplastic elastomer
  • this base support is connected to the neck region of a toothbrush handle, not shown.
  • a plurality of support rings 2 are arranged distributed in the base support 1 and embedded in these. Each of the support rings 2 is provided as a separate component in the base support 1.
  • the support rings 2 are formed as cylindrical components of any cross-section and form a cylindrical recess 3, which may have a round, polygonal or rectangular cross-sectional shape.
  • the support rings 2 are preferably made of polypropylene (PP) and each take a bundle of bristles 4, which consists of polyamide filaments in a conventional manner, in itself.
  • An end of the bundle of bristles which projects beyond the support ring 2 at the end has a thickening 5 which is formed by melting the polyamide filaments and connecting all the individual filaments together.
  • the thickening has a diameter which is greater than that of the recess 3 of the support ring 2.
  • the individual support rings 2 are covered on the back by the soft elastic material of the base support 1. Accordingly, the soft elastic material of the base support 1 forms the rearward outside of the brush head shown. This is completely flat. However, the brush head has a height that is only slightly higher than the depth of embedding of the individual bristle bundles 4, ie the length of the bristle bundle 4 surrounded by the base support 1 including the thickening 5. Due to the elastic properties of the soft elastic material, as well as the small wall thickness of the base support 1 between the rear outer surface and the mounting side end of the bristle bundle 4, this can be moved in limits in the axial direction relative to the support ring 2. This case, in which an axial force acts in the direction of the arrow on the bristle bundle 4, is shown in FIG.
  • the bristle bundle 4 Due to the effective axial stress, the bristle bundle 4 has moved relative to the support ring 2. Accordingly, the thickening 5 was lifted from a front end 6 of the support ring 2. The soft elastic plastic of the base support 1 located on the back of the thickening 5 forms a slight curvature in this load case on the rear side of the brush head.
