Definitions
- the invention relates to a brush head for a Toothbrush according to the preamble of claim 1.
- FR-A-683 311 is a toothbrush with a Generic brush head known, each with one Double row of in the longitudinal direction of the brush head inclined, crossing bristle tufts with one transverse row each at right angles to the bristle holder alternating standing bristle tufts.
- the latter Tufts of bristles are the same length among themselves and shorter and thicker than the slanted tufts of bristles.
- the last transverse row in the front area of the brush head is formed by inclined tufts of bristles. At the Cleaning the teeth will make the toothbrush vertical Direction back and forth, which thanks to the mentioned special arrangement of the tufts of bristles improved cleaning of both the tooth surfaces and the Interdental spaces leads.
- Fig.2 is a toothbrush discloses whose tufts of bristles with their free-standing Form ends of a brush surface consisting of two parts.
- One part of the brush surface is flat and is covered by the Ends of substantially perpendicular to the bristle carrier standing tufts of bristles of the same length are formed.
- the other brush surface part is in the longitudinal direction of the Brush head tilted and rises to the front end of the Brush head.
- This inclined part of the brush surface is formed by the ends of tufts of bristles approximately at a right angle from the end portion of the Protrude bristle carrier.
- the object of the present invention is now Reason to create a brush head that one in Comparison to the previously known generic brush head further improved cleaning of the teeth and the Interdental spaces enabled.
- DE-A-44 12 301 is a slip-on toothbrush known for an electric toothbrush whose Bristle carriers across the entire length with rows of bristle tufts is provided in the longitudinal direction have inclined tufts of bristles.
- the Bristle holder is motorized in by a drive part Direction of a surface approximately perpendicular to the surface to be cleaned Axis of motion in such oscillating tapping movements offset that the tufts of bristles due to their Oblique with their ends oscillating over the surface to be cleaned pushed and withdrawn become.
- Bristle holder from the drive for further cleaning movements be granted, e.g. one oscillating around its longitudinal axis Partial rotation or a reciprocation in the longitudinal and / or transverse direction.
- the brush head 2 has a bristle holder 3, in each of which a plurality of bristles formed bristle tufts 4, 5, 6 are anchored. With 4 those tufts of bristles are designated that are essentially directed perpendicular to the bristle carrier 3 are. They are also inclined to the bristle holder Bristle tufts 5, 6 are present, the bristle tufts 5 in the longitudinal direction of the toothbrush behind, the bristle tufts 6, however, inclined forward are. The angle of inclination of these tufts of bristles 5, 6 with respect to the vertical can be up to 45 ° (in the drawing is a smaller angle of inclination ) Shown. Form the free-standing ends of all bristles an optionally flat brush surface 10 (FIG. 3). The longitudinal axis of the toothbrush 1 is designated 7 in FIG. 2.
- All slanted Bristle tufts 5 or 6 of a transverse row 15 and 16 have the same angle of inclination.
- the Tilt angle of the bristle tufts 5 of a transverse row 15 of a pair of transverse rows 15, 16 compared to the Vertical equals the negative angle of inclination Bristle tufts 6 of the other transverse row 16, so that a longitudinally symmetrical X-structure is created.
- the two transverse rows 15, 16 with the crossing, inclined bristle tufts 5, 6 are in one about an average tooth width Distance arranged.
- FIG. 4 to 6 show a further variant of a manual toothbrush equipped with a brush head 2a 1a.
- the bristle carrier, the upright and inclined tufts of bristles and the corresponding Cross rows are still with the same reference numbers designated as in Figs. 1 to 3.
- this embodiment is only one group out of three Bristle tufts standing perpendicular to the bristle carrier 3 4 transverse rows 14 formed, the - in Seen longitudinal direction of the toothbrush - between each two pairs of transverse rows 15, 16 is arranged, the with sloping tufts of bristles crossing in pairs 5, 6 are provided.
- This variant too the free-standing bristle ends form a flat surface Brush surface 10 (Fig. 6).
- a third embodiment shown in FIGS. 7 to 9 a manual toothbrush 1b with a brush head 2b essentially corresponds to the first variant 1 to 3; the transverse rows 14 have the same Number of tufts of bristles, but the outermost ones Outer tufts 18, 19 of each transverse row 14 are in Cross direction of the toothbrush inclined outwards (Fig. 8 and 9). Even those with the inclined in the longitudinal direction Bristle tufts 5, 6 provided, with the middle Group of transverse rows 14 adjacent transverse rows 15, 16 is an outer tuft 20, 21 or 22 on each side, 23 assigned, each in the longitudinal direction, as also in the transverse direction of the toothbrush 1b to the outside is inclined (see FIG. 8).
- the outer tufts 18 20, 22 and 19, 21, 23 each form one in this way lateral longitudinal row 26, 27 from in the transverse direction bristle tufts protruding from the outside.
- the brush surface formed by all tufts of bristles 10 is in turn flat (Fig. 9).
- 10 to 12 is a fourth variant of a Manual toothbrush 1c shown with a brush head 2c, which is a group of four and two groups of two transverse rows 14 perpendicular to the bristle carrier 3 has standing bristle tufts 4, between which each two transverse rows 15, 16 with the bristle carrier 3 inclined in the longitudinal direction, in pairs crossing bristle tufts 5, 6 are arranged.
- toothbrushes 1, 1a, 1b and 1c during the tooth cleaning process the perpendicular to the bristle holder 3 standing bristle tufts 4 especially for cleaning tooth surfaces. With the lengthways the toothbrush tilts 5, 6 the interdental spaces are better reached and the gum line (i.e. the area of the transition Teeth / gums) treated more effectively.
- the tooth cleaning process i.e. in the float the toothbrush come in the longitudinal direction when moving in one direction to the rear inclined bristle tufts 5 of the transverse rows 15, in the Moving in the other direction the others, after Bristle tufts 6 inclined at the front of the transverse rows 16 to the effect, namely for better penetration into the difficult to reach interdental spaces.
- the inventive Brush heads 2, 2a, 2b, 2c a fixed part the respective manual toothbrush 1, 1a, 1b, 1c. You could but also a part of a handle Electric toothbrush attachable toothbrush form. In both cases, the bristle holder could also releasably arranged on the corresponding holding part his.
