Definitions
- the invention relates to a brush for dental and personal care, consisting of a bristle carrier and bristle bundles attached to it, the ends of the bristles lying in at least two different planes perpendicular to the bristle extension.
- the individual tooth also has different curvatures on the outside and inside and, finally, the occlusal surface in the molar area is again designed differently than the outer or inner tooth surface.
- the inadequate cleaning effect of the aforementioned toothbrushes with a flat work surface and dense bristle stock is essentially due to the bristles being supported with one another, with the result of the deflection of the bristles in each case counter to the direction of movement, and the inadequate adaptation of the work surface to the different teeth or tooth contours.
- the bristle bundles having different lengths and / or different angular positions. It is known (US Pat. No. 4,010,509) to make the bristle bundles arranged in the central longitudinal extension of the bristle carrier shorter than the bundles arranged on both sides in the edge region, which are also set at an angle. With regard to the deflection of the bristles, however, the same applies to the individual bundle as to the toothbrush mentioned above.
- the bundles of the same length generally turn in one direction, namely against the direction of movement.
- the bristles of each bundle are of different lengths and form a concave or convex active surface and, finally, the bundles can also have two different lengths from one another by being longer in the front area of the brush than in the rear area .
- the shorter bundles can inevitably only be effective in one direction of movement if they are in front of the longer bundles in the direction of movement. When moving in the opposite direction, they are encroached upon by the longer bundles which fold over and are therefore ineffective.
- the invention is therefore based on the object of proposing an arrangement in the case of a brush of the construction mentioned at the outset which enables the active surfaces of the bristle bundles to be optimally matched to the given teeth and tooth contours, regardless of the brushing technique used in each case.
- a contouring of the work surface can be divided into the smallest active surfaces of different levels, so that they are at Bite contour have a different depth of penetration, on the other hand the support of the bristles among themselves is reduced, so that they adapt to the given curvatures better or longer bristles dodge more easily and the shorter bristles have a better effect.
- the ends of the bristles of a single bundle or the ends of the bristles of three adjacent bundles lie in three different planes.
- the ends of the bristles of a bundle can lie on concentric levels; instead, the levels of the same level can extend several bundles along or across the bristle carrier. The orientation of these planes can also vary in the longitudinal extent of the bristle carrier.
- the bristles, the ends of which lie in the same plane have a diameter that is identical to one another, but different from that of the bristles, the ends of which lie in a different plane.
- the rigidity of the bristles, the ends of which lie in a common effective area can be designed differently than that of the bristles, the ends of which are arranged in a different plane.
- the bristles the ends of which lie in one plane, have properties which differ from those of the bristles, the ends of which lie in a different plane, e.g. Have material, surface, color, etc.
- bristle holder with bristle trimmings.
- 25 bristle bundles are arranged on an area of 6 cm 2, the bundles also being spaced apart by a distance of 0.6 mm, so that four bundles are arranged on about 6 mm 2.
- Such an arrangement can be realized by optimizing the latest manufacturing technologies.
- FIG. 1a shows a section of a toothbrush manufactured using this manufacturing technology with a conventional bristle or bundle arrangement. It consists of a bristle carrier 1 and bundles 2, which are each formed from a plurality of bristles 3.
- the bristle bundles 2 have the same length, so that their ends lie on a flat envelope surface which forms the working surface 4.
- FIG. 1b shows schematically a bit in the anterior region with the anterior teeth 5 and the first molar 6 adjoining the anterior region.
- the ends of the bristle bundles 2 fold against the direction of movement, as can be seen in the bristle bundle 2 shown on the left. In between, the bristle bundles spread out, but without their ends having a significant effect, while the bristle bundles 2 shown further to the right remain without any effect. In particular, it can be seen that the bristles do not penetrate the interdental spaces, or only very insufficiently.
- FIG. 2a shows a toothbrush according to the invention, in which bristle bundles 8 are in turn attached to the bristle carrier 7 in the arrangement shown in FIG. 7.
- the bristles 9 of each bundle 8 or groups of bristles are of different lengths, so that their ends in the embodiment shown are in three stepped working planes 10, 11 and 12, respectively.
- FIG. 2b shows the toothbrush according to FIG. 2a in one of the usual positions of use when cleaning the teeth on the outside of the teeth. Again, the front teeth 5 and the first molar tooth 6 can be seen. When the bristles are pressed on, they evade in a much more varied manner during the cleaning movement, as is clear from a comparison of FIGS. 1b and 2b.
- each bundle 10 has central bristles 11, the ends of which are on one Active surface 12 lie, as well as groups of bristles 12 and 13 arranged on both sides of bristles 11, the ends of which in turn lie in two different active surfaces 15, 16.
- FIG. 3b The effect of such an embodiment can be seen from FIG. 3b.
- Figure 4a shows a single bristle bundle 2 corresponding to the embodiment of Figure 1a.
- the bristles 3 of such a bundle 2 which essentially has the indicated circular shape, have the same length.
- FIG. 4b shows a single bristle bundle 8 corresponding to the embodiment according to FIGS. 2a to d.
- the ends of the bristles of such a bundle 8 are stepped in three planes transverse to the bundle extension.
- FIG. 4c shows an annular gradation of the active surfaces of the bristles of a bundle 20, namely with an outer group of bristles 21 of the shortest length, a middle group of bristles 22 of medium length and a central group with bristles 23 of the greatest length.
- the reverse arrangement is provided on a bundle of bristles 24.
- This therefore has a central group of bristles 25 of the smallest length, a group of bristles 26 of medium length surrounding this concentrically and an outer group of bristles 27 of the greatest length.
- the active surface of adjacent bundles can also be at different levels in the arrangement according to FIG.
- FIG. 5a shows two adjacent bundles 28, 29, the cross section of which is in the form of a segment of a circle, the bristles of the bundle 28 having a greater length than that of the bundle 29.
- the exemplary embodiment according to FIG. 5b three bundles with a circular cross section are in the arrangement according to FIG. 7 of different lengths, the bundle 30 having the longest bristles, the bundle 31 having the medium length bristles and the bundle 32 having the shortest length.
