Definitions
- the invention relates to a brush for the tooth and Body care, consisting of a bristle holder and an this attached bristle bundle, the ends of the Bristles of adjacent bundles in at least two different, planes perpendicular to the bristle extension.
- toothbrushes Factors are decisive. They range from purely geometric Dimensions such as bristle diameter, bristle length and Area of the bristle field, about the bristle density, the Bristle material, the strength properties, such as bending ability and re-erection ability until order the bristles within the bristle stock.
- the individual tooth also has different outside and inside Curvatures on and finally is in the molar area the purchase area in turn designed differently than the outer or inner tooth surface.
- the inadequate cleaning effect the aforementioned toothbrushes with flat Work surface and dense bristle trimmings are based essentially on the support of the bristles with each other the consequence of the deflection of the bristles against the Direction of movement, and the inadequate adjustment of the Work surface on the different teeth or tooth contours.
- the bristle bundles have different lengths (FR-A-2 587 183) and / or have different angular positions. So it is known (US 4 010 509) in the middle Longitude of bristle bundles arranged in the bristle carrier to be shorter than that on both sides in the edge area arranged bundles, which are also angled are. With regard to the deflection of the bristles applies here however, the same for the individual bundle as for the previously mentioned toothbrush. The bundles of the same length usually turn in one direction, namely against the direction of movement.
- the bristles of each bundle have different lengths and form a concave or convex surface and can finally the bundles among themselves two different ones Have lengths by being in the front of the Brush are longer than in the rear area.
- bristle bundles with different Bundle diameters and different lengths to be arranged in groups the effective surfaces of the bristle ends in two different levels, which are in the essentially perpendicular to the longitudinal extension of the bristle carrier run.
- the shorter bundles can inevitably only be effective in one direction of movement if they namely in the direction of movement in front of the longer bundles lie. With the opposite movement they become overlapped by the longer bundles and so ineffective.
- the bristle bundles In a known toothbrush, which forms the preamble of claim 1 (US-A-4 672 706), the bristle bundles have different lengths and the bundles are arranged comparatively closely. A bundle sits on an area of 6.4mm 2 . This already achieves a good cleaning effect and, due to their different lengths, the bundles can also follow the tooth contour well.
- the invention is therefore based on the object a brush according to the preamble of claim 1 (US-A-4 672 706) propose an arrangement that includes a optimal adaptation of the effective area of the bristle bundle the given teeth and tooth contours enables, and regardless of the brushing technique used.
- the arrangement of at least two bristle bundles on an area of at most 6 mm 2 initially creates the possibility of minimizing the effective areas given by the ends of each bristle bundle.
- the entire working surface of the bristle trimmings is thus broken down into the smallest possible surface elements with a tight arrangement of the same, so that the bundles on the bit contour have a different penetration depth, and on the other hand the support of the bristles among themselves is reduced so that they adapt better to predetermined curvatures or longer bristles dodge more easily and the shorter bristles work better.
- the ends of the Bristles from three neighboring bundles in three different ones Levels are identical to the ends of the Bristles from three neighboring bundles in three different ones Levels.
- the ends of the bristles of a bundle can concentric levels, instead the Levels of the same level are several bundles along or extend across the bristle holder. Alignment can also of these levels in the longitudinal extension of the bristle carrier vary.
- the ends of the bristles of a single bundle in the at least two different levels can be a contouring of the work surface in Divide the smallest effective areas of different levels.
- the stiffness of the bristles, the ends of which lie in a common effective area differently shape as that of the bristles, the ends of which are in one another level.
- the bristles, the Ends lie in one plane, from those of the bristles, the ends of which are on a different plane, different ones Properties, e.g. Material, surface, color etc. exhibit.
- bristle holder with bristle trimmings.
- 25 bristle bundles are arranged on an area of 6 cm 2 , the bundles also being at a distance of 0.6 mm from one another, so that four bundles are arranged over approximately 6 mm 2 .
- Such an arrangement can be realized by optimizing the latest manufacturing technologies.
- Figure 1a shows a section of a manufacturing technology manufactured toothbrush with conventional Bristle or bundle arrangement. It consists of a bristle carrier 1 and bundles 2, each of which several bristles 3 are formed.
- the bristle bundle 2 have the same length, so that their ends on a lie flat envelope that forms the working surface 4.
- FIG. 1b A bit in the anterior region is schematically shown in FIG. 1b with the front teeth 5 and the first on the front tooth area subsequent molar tooth 6 shown.
- the bristle bundles 2 put on during the cleaning movement their ends against the direction of movement around like this at the bristle bundle 2 shown on the left is recognizable.
- the bristle bundles spread between them on, but without a significant effect with their ends to unfold while the bristle bundle shown further to the right 2 remain without any effect.
- the bristles are not or only very insufficient penetrate between the teeth.
- Figure 2a shows a toothbrush according to the invention, at the bristle bundle 8 in turn on the bristle carrier 7 in the Fig. 7 arrangement shown are attached.
- the bristles 9 each bundle 8 or groups of bristles are different long so that their ends are shown Embodiment in three stepped action levels 10, 11th or 12 are.
- FIG. 2b the toothbrush according to FIG. 2a is in one of the usual positions of use when cleaning the teeth on the Teeth outside shown. Again, there are the front teeth 5 and the first molar tooth 6 can be seen. When pressing the Bristles soften under the cleaning movement much more diverse, like this one Comparison of Figures 1b and 2b becomes clear.
- each has Bundle 10 central bristles 11, the ends of which on one Effective surface 12 and on both sides of the bristles 11th arranged groups of bristles 12 and 13, the ends of which again lie in two different active surfaces 15, 16.
- the effect of such an embodiment is shown in FIG. 3b evident.
- Figure 4a shows a single bristle bundle 2 accordingly the embodiment of Figure la.
- a single bristle bundle 8 is corresponding the embodiment shown in Figures 2a to d.
- the Ends of the bristles of such a bundle 8 are in three Tiered levels across the bundle extent. Besides one There is a segment with bundles 17 of greatest length Segment with bundles 18 of medium length and next to it Segment with bundles 19 of the smallest length.
- Figure 4c shows an annular gradation of the active surfaces of the bristles Bundle 20, namely with an outer group of bristles 21 of shortest length, a middle group of bristles 22 medium length and a central group with bristles 23 greatest length.
- Bristle bundle 24 provided the reverse arrangement. This therefore has a central group of bristles 25 smallest length, a group concentrically surrounding this of medium length bristles 26 and an outer group of Bristles 27 of greatest length.
- Figure 5a shows two adjacent bundles 28, 29, the Cross section is segment of a circle, the bristles of the Bundle 28 have a greater length than that of the bundle 29.
- Figure 5b three bundles of circular cross section in the arrangement 7 of different lengths, the Bundle of 30 longest bristles, the bundle of 31 bristles medium length and the bundle 32 bristles of the shortest length having.
