Definitions

  • the invention relates to a toothbrush according to the preamble of claim 1.
  • tooth pockets i.e. Cavities below the edge of the gums on the tooth neck. Food residues easily get caught in these tooth pockets, which then lead to inflammatory processes.
  • One of the main causes of this phenomenon is the dental plaque or the dental plaque, which pushes itself under the gums and detaches them from the tooth neck.
  • a number of special toothpaste compositions have already been developed to combat this phenomenon, but nothing was known to counter this on the part of toothbrush design.
  • the invention is based on the object of brush or a bristle holder so that they counteract the phenomenon discussed above in the best possible way. This is achieved in a surprisingly simple manner by the features of the characterizing part of claim 1.
  • the bristle holes are arranged in the shape of an arc or along an arc, they adapt to the arches formed by the gumline on normal teeth when the brush is held appropriately or when it is arranged accordingly. As clinical trials to be discussed later, this is the best way to clean the marginal and interdenta en gingiva. This adjustment is particularly supported if the bristle holders are connected to the handle via elastic webs in a manner known per se and will be explained later and / or the bristles are of different lengths or hardness in the manner shown in the drawing. In particular, if the toothbrush is designed as an electric toothbrush, of course, it is sufficient if the associated bristle holder, which can be releasably attached to it, is designed in the manner described in the characterizing part of claim 1.
  • the training is preferably made according to claim 3.
  • this allows the same to be used in any position, and also allows the upper and lower rows of teeth to be cleaned without having to change the position of the toothbrush.
  • brushes designed in this way bring an improved cleaning effect to an even greater extent, as has been demonstrated on the basis of comparative tests.
  • toothbrush If the toothbrush is designed according to claim 4, its shape approximates that of the optimized design as described in the two WO documents mentioned at the beginning.
  • a bristle holder according to the invention has the features of claim 7, whereby it - in contrast to the usual rectangular shape in plan view - becomes approximately square.
  • This square shape is in connection with the above explanations for claim 1, because if it is important to adapt the toothbrush to the course of the gum line on the tooth neck, this shape works best.
  • this shape is not necessarily tied to the realization of the features of claim 1, because it can - in place of the arcuate configuration - the bristles also be adjusted in that the holes fill a square area, but softer at the corners of this square Bristles are provided so that the hard bristles are again arranged approximately along an arc. Also by different angular positions of the bristles arranged at the corners relative to the arranged in between achieve the desired adaptation to the arches of the gum line.
  • the embodiment according to claim 9 will be of particular interest if the bristle holder is intended for electric toothbrushes, but it can also be used for manually operated toothbrushes.
  • Figure 1 is a front view of a known toothbrush on which the invention is preferably implemented.
  • FIG. 2 shows a greatly enlarged section along the line II-II of FIG. 1, the image of a row of teeth being drawn with dash-dot-dash lines for comparison;
  • FIG. 3 shows a variant of FIG. 2 in a corresponding section
  • FIG. 4 shows a further variant, but in a top view along the line I - IV of FIG. 1.
  • a connecting web 3 extends transversely or perpendicularly to the main axis 2 of the handle 1.
  • This connecting web 3 carries bristles 4 which are intended to act on the chewing surfaces of the teeth upwards and downwards.
  • bristle holders 5 are articulated transversely thereto via a plastic joint 6, so that they can be bent apart elastically with deformation of the plastic joint 6 if a tooth is between two bristle holders 5 with opposing bristles 7, 8 is introduced.
  • FIG. 1 describes only a very narrowly limited part of a joint 6 as the bristle holder 5
  • the bristle holder 5 may also include connecting lugs, in particular if this is the case is an attachable or releasably attachable bristle holder.
  • Fig. 2 three teeth next to each other are indicated by dash-dotted lines at 9.
  • the teeth 9 sit in the upper jaw and are covered at the top by the marginal gingiva 10, which runs in an arch-like manner in 90% of the inhabitants of cultivated countries.
  • at least one edge zone of the bristles 8 (FIG. 1) is arranged in a corresponding arc shape in bristle holes 8 '.
  • "Correspondingly” means preferably that the arc 11 indicated by dash-dotted lines, on which the holes 8 1 are located, has a radius in the ranges from 3 mm to 10 mm, the latter digit actually representing the top area. It is advantageous to measure the arc radius not greater than 8 mm at maximum.
  • radii of 5 mm + 20% have proven particularly useful, although, as will be explained, it is quite conceivable and desirable to dimension the arc radii of different bristle hole arcs differently on the bristle holder or within the bristle field 12 arranged thereon .
  • the central bristles 15 are arranged such that they, together with the two bristles at the end, holes in the arch 13 also result in an arc 16 which is parallel to the arc 11.
  • the arrangement of the bristle holes shown now entails that the bristle holder 5 - as can be seen - is almost square in plan view of the bristle field 12 (although it would be entirely possible for simple toothbrushes with only one bristle holder and handle, according to the contour 10 consecutive arches 11), the diagonals through the bristle holder 5, which are shown here as dashed lines 17, enclosing an angle with one another in the range from 75 ° to 105 °, that is to say on average about 90 ° + 10%. It is irrelevant whether this angle is measured at the position alpha shown in FIG. 2 or its associated complementary angle, because both angles must necessarily lie in this area.
  • the resulting weakly rectangular to square shape is not only advantageous for toothbrushes of the type shown in FIG. 1, although it is also most easily applicable there and in combination with whose special features (see above) exorbitantly improve the cleaning result in a synergetic way. Rather, the explanation based on tooth contours 9, 10 shows that such a shape is also particularly suitable for conventional toothbrushes for cleaning and massaging the marginal gingiva and its adjacent areas on the tooth surface.
  • the density of the bristle holes plays a role, which should be about 25 to 30 holes per cm in order to achieve favorable results.
  • the angle alpha does not yet say anything about the specific size of the bristle holder 5, which is supposed to be adapted to the average size of the arches 10.
  • Tests have shown that an edge length 1 or L (cf. FIG. 3) of the order of 5 to 15 mm and in particular 5 to 10 mm corresponds best to the average.
  • L edge length 1 or L (cf. FIG. 3) of the order of 5 to 15 mm and in particular 5 to 10 mm corresponds best to the average.
  • the lower limit of approximately 5 mm (-10%) is somewhat more critical than the upper limit.
  • the bristle field 112 here also has bristle holes 18 which, together with the other bristle holes, delimit an - initially almost conventional-looking, bristle field of rectangular shape.
  • the difference from the prior art lies in the fact that the bristles of the bristle holes 18 are only very soft, whereas the hard bristles of the bristle holes 7 ', 8' and 15 again, as in FIG. 2, along arches 11, 13 and 16 are arranged.
  • the middle message holes 15 can also be viewed as being located on a sheet 19 running parallel to the sheet 13.
  • at least one arc 16 parallel to the arch 11 of the outer handle 1 (see FIG. 1) facing away from the bristle row is realized, since this supports, as above explains, massage and cleaning of the marginal, but ultimately also the inter ⁇ dental gingiva, which counteracts the formation of tooth pockets.
  • FIG. 4 illustrates a top view of a further embodiment variant.
  • the bristles 7, 8 protrude approximately perpendicular to the plane of the bristle holder or the bristle field 12, or that there is no great deviation from the perpendicular (maximum 10 °).
  • the edges of the bristle field 212 which are curved in plan view can also be achieved by arranging individual bristles 8 and 15 'perpendicular to the plane of the brush holder 205 or the bristle field 212, but that the bristles 8 "and 7" are inclined in opposite directions in such a way that their ends are each located on an arc 11 'or 13', although it would be ascertained in the case of a cut through the bristles that their bristle holes are on or within a Rectangle 20 lie.
  • the bristles 7 ′ ′′ located at the end of the arch 13 ′ can also be arranged obliquely, as can be seen from FIG. 4, namely opposite to the inclination of the bristles 7 ′′. But this also results in an arc 16 'from a line connecting the ends of the bristles 15' with those of the bristles 7 "'.
