Definitions
- the invention relates to a brush head for a toothbrush according to the preamble of claim 1.
- Brush heads of this type come in a wide variety of designs known.
- the present invention has for its object a Brush head to create an improved cleaning teeth and interdental spaces.
- both transverse rows with the bristle carrier in essentially vertical tufts of bristles as well at least one pair of transverse rows in the longitudinal direction the toothbrush is slanted, crossing each other Bristle bundle is present, both will flawless cleaning of the tooth surfaces, as well as a better penetration into the interdental spaces.
- DE-A-44 12 301 is a slip-on toothbrush for one Electric toothbrush known, the bristle holder on the entire length is provided with rows of bristle tufts, which have bristle tufts inclined in the longitudinal direction.
- the bristle carrier is driven by a drive part motorized in the direction of a surface to be cleaned about vertical axis of motion in such oscillating Knocking movements offset that the bristle tufts due to their inclination with their ends oscillating over the surface to be cleaned pushed and pulled back.
- the bristle carrier can Other cleaning movements are given, e.g. a partial rotation oscillating about its longitudinal axis or a back and forth movement in the longitudinal and / or transverse direction.
- FIG. 1 to 3 show a front part of a manual toothbrush 1, which is equipped with a brush head 2.
- a brush head 2 has a bristle carrier 3, in which tufts of bristles each formed from a plurality of bristles 4, 5, 6 are anchored. At 4, those are tufts of bristles referred to, which is substantially perpendicular to Bristle carrier 3 are directed.
- the angle of inclination of these bristle tufts 5, 6 compared to the vertical can be up to 45 ° (in the Drawing is shown a smaller angle of inclination).
- the free ends of all bristles form one if necessary flat brush surface 10 (Fig. 3).
- the longitudinal axis of the Toothbrush 1 is designated 7 in FIG. 2.
- All inclined bristle tufts 5 or 6 of a transverse row 15 and 16 have the same angle of inclination on.
- the angle of inclination of the tufts of bristles 5 a transverse row 15 of a transverse row pair 15, 16 opposite the vertical is equal to the negative angle of inclination Bristle tufts 6 of the other transverse row 16, so that an in Longitudinal symmetrical X-structure is created.
- the two Cross rows 15, 16 with the intersecting, inclined Tufts of bristles 5, 6 are roughly average Tooth width corresponding distance arranged.
- FIG. 4 to 6 show a further variant of one with a Brush head 2a equipped manual toothbrush 1a.
- the bristle carrier, the upright and inclined tufts of bristles and the corresponding cross rows are still designated by the same reference numerals as in FIG. 1 to 3.
- the free-standing bristle ends have a flat brush surface 10 (Fig. 6).
- a third embodiment shown in FIGS. 7 to 9 corresponds to a manual toothbrush 1b with a brush head 2b essentially the first variant according to FIG. 1 to 3; the transverse rows 14 have the same number of Bristle tufts, but the outermost side tufts 18, 19 of each transverse row 14 are in the transverse direction Toothbrush inclined outwards (Fig. 8 and 9). Also the with the bristle tufts 5, 6 inclined in the longitudinal direction provided, with the middle group of transverse rows 14 adjacent Transverse rows 15, 16 is a tuft at each side 20, 21 or 22, 23 assigned, each in both Longitudinal direction, as well as in the transverse direction of the toothbrush 1b is inclined towards the outside (see Fig. 8).
- the outside tufts 18, 20, 22 and 19, 21, 23 form on this One lateral longitudinal row 26, 27 each in the transverse direction tufts of bristles protruding outwards.
- the brush surface 10 formed by all ends of the tufts of bristles is again flat (Fig. 9).
- 10 to 12 is a fourth variant of a manual toothbrush 1c with a brush head 2c, the one Group of four and two groups of two transverse rows 14 with bristle tufts standing perpendicular to the bristle carrier 3 4, between each of which two transverse rows 15, 16 with the bristle carrier 3 inclined in the longitudinal direction, bristle tufts 5, 6 crossing in pairs are arranged.
- the inclined ones protrude Bristle tufts 5, 6 in height most of the upright tufts of bristles 4; but also the front one Group of bristle tufts perpendicular to the bristle carrier 3 4 has tufts 4 of different lengths on, so that in the front area of the brush head 2c longitudinally inclined, the front end of the brush head 2c in addition rising brush surface part 29 is formed will (Fig. 10).
- Toothbrushes 1, 1a, 1b and 1c take care of the tooth cleaning process the bristle tufts perpendicular to the bristle carrier 3 4 especially for cleaning tooth surfaces.
- Tufts of bristles 5, 6 improve the interdental spaces reached and the gum line (i.e. the area of the Transition teeth / gums) treated more effectively.
- the tooth cleaning process i.e.
- the toothbrush in the longitudinal direction come when moving the bristle tufts inclined backwards in one direction 5 of the transverse rows 15 when moving in the in the other direction the other bristle tufts inclined forward 6 of the transverse rows 16 to effect, namely to better penetration into the difficult to reach interdental spaces. While these are inclined in one direction and in the bristle tufts 5 effective in one direction of movement or 6 knock on the teeth and into the interdental spaces the bristle tufts are inclined differently 6 or 5 dragged over the tooth surfaces and have a wiping effect. In the other direction the roles of the tufts of bristles 5,6 are exchanged.
- the brush heads according to the invention form 2, 2a, 2b, 2c a fixed part of the respective Manual toothbrush 1, 1a, 1b, 1c.
- the bristle carrier could also be detachably attached to the corresponding one Holding part can be arranged.
