Definitions

  • the present invention relates to a brush head for a toothbrush according to the preamble of claim 1.
  • the bristle carrier consists of a material which is hard at room temperature and which surrounds the bristle bundles at one end.
  • the present invention has for its object to provide a brush head of the type mentioned, which allows better adaptation to the shape of the bit to be cleaned and the individual teeth.
  • the bristle holder is given increased flexibility. This allows the bristle bundles to adapt better to the shape of the teeth and teeth during use.
  • Line II-II in Fig. 1 shows a first embodiment of a brush head
  • FIG. 5 shows a third variant of the first exemplary embodiment in section corresponding to the representation according to FIG. 2,
  • Line VII-VII in Fig. 6 shows a second embodiment of a brush head
  • Fig. 8 u. 9 is a top and side view of a third embodiment of a brush head
  • Fig. 10 u. 11 shows a section along the line X-X in FIG
  • FIG. 14 a fifth embodiment of a brush head.
  • a brush head 1 and part of the handle 2 of a toothbrush is shown in plan view and in Fig. 2 in section along the line II-II of Fig. 1.
  • the brush head 1 has a bristle carrier 3, in which projecting bristle bundles 4, each of which consists of a plurality of bristles, are anchored. At the anchoring end, each bundle of bristles 4 is fastened in a sleeve 5.
  • the sleeves 5 with the bristle bundles 4 are spaced apart and, in the present exemplary embodiment, are arranged, for example, in rows which extend parallel and at right angles to the longitudinal axis A of the toothbrush.
  • the bristle carrier 3 consists of a soft, elastic material which is elastically compressible and stretchable, for example of an elastomer.
  • the sleeves 5 are embedded in this rubber-elastic material, which on the one hand establishes the connection of the sleeves 5 with one another and on the other hand gives the bristle carrier a certain flexibility.
  • the bristle bundles 4 are not inserted individually into the soft elastic material of the bristle carrier 3, but are combined into groups 6.
  • the bristle bundles 4 of each group 6 are connected to one another by means of connecting parts 7 serving as holding parts.
  • Each connecting part 7 has holes 7a into which the bristle bundles 4 are inserted.
  • the connecting parts 7 are completely or partially surrounded by the soft elastic material of the bristle carrier 3.
  • the connecting parts 7 extend transversely, preferably approximately at right angles to the toothbrush longitudinal axis A.
  • Each group 6 thus consists of a number of bristle bundles 4 arranged next to one another in the connecting part 7.
  • the configuration in the variant according to FIG. 4 is more versatile since the connecting parts 7 have different shapes.
  • a third variant of the first exemplary embodiment is partially shown in section in FIG. 5.
  • the sleeves 5 are of a bristle bundle group 6, e.g. a longitudinal or transverse row, interconnected by means of flexible connecting webs 8. These connecting webs 8 are completely embedded in the material of the bristle carrier 3.
  • All sleeves 5, in which the bristle bundles 4 are anchored at one end, are connected to one another, by means of a connecting part 9 (FIG. 7) which forms the rear side of the bristle carrier 3.
  • This connecting part 9 is relatively thin and flexible.
  • a cover layer 10 made of a soft elastic material, e.g. an elastomer. This soft elastic material surrounds the sleeves 5 and fills the spaces between these sleeves 5.
  • the cover layer 10 made of rubber-elastic material largely determines the elastic properties of the bristle carrier 3.
  • FIGS. 8-11 A third embodiment of a brush head according to the invention is shown in FIGS. 8-11.
  • holders 12 are provided for the bristle bundles 4, which are arranged at a distance from one another and, in the exemplary embodiment shown, extend at right angles to the toothbrush longitudinal axis A and run parallel to one another.
  • a number of bristle bundles 4, in the present case three bristle bundles 4, are anchored in each holder 12.
  • Holder 12 is connected at its two ends via a joint 13 (FIGS. 10 and 11) to a frame 14 which is integral with the handle 2.
  • the frame 4 is rectangular and has two mutually parallel longitudinal legs 14a and 14b, on which the joints 13 are attached.
  • the frame 14 may also have a shape other than rectangular and e.g. also be oval or round.
  • each holder 12 defines a tilt axis B, which in the exemplary embodiment shown is perpendicular to the longitudinal axis A of the toothbrush.
  • Each holder 12 is pivotable about its tilt axis B. It is also possible to arrange the holders 12 in the frame 14 such that the tilt axes B run obliquely to the longitudinal axis A of the toothbrush.
  • the frame 14 is provided with an upper cover 15 and a lower cover 15 ', both made of a soft elastic material, e.g. an elastomer.
  • the material of the covers 15, 15 ' extends through the spaces 16 between the holders 12 (FIG. 11), whereby the covers 15, 15' are connected to one another.
  • the mobility of the holder 12 with the bristle bundles 4 inserted is determined by the rubber-elastic material of the covers 15, 15 'surrounding them.
  • the bristle bundles 4 are anchored in a thin, flexible holding part 17.
  • the latter is made in one piece with the handle 2, ie it is made of the same material.
  • a lower cover layer 18 made of a flexible material is attached on the underside of the holding part 17 belonging to the bristle carrier 3.
  • the holding part 17 is provided with an upper cover layer 19, which is also made of a flexible material.
  • the holding part 17 forms, together with the cover layers 18 and 19, a sandwich construction, the flexibility of which is determined by the flexible properties of the holding part 17 on the one hand and the cover layers 18, 19 on the other hand.
  • the fifth embodiment shown in FIGS. 14 and 15 has a bristle carrier 3 which is made of the same material as the handle 2 and is integral with it.
  • the bristle bundles 4 are anchored in this bristle carrier 3.
  • a groove 24 is provided in the bristle carrier 3 and runs in the direction of the longitudinal axis A of the toothbrush. This groove 24 is filled with an insert 25 made of a flexible material.

Abstract

Selon l'invention, les groupes de poils (4) sont ancrés dans des douilles (5) maintenues dans le support de poils (3). Ce dernier est constitué d'un matériau élastique et souple, par ex. un élastomère, qui entoure les douilles (5). Ces dernières (5) et les groupes de poils (4) sont ainsi incorporés dans ce matériau élastique et souple qui relie les douilles (5) entre elles et confère une certaine flexibilité au support de poils (3), et par conséquent à l'ensemble de la tête (1).
