Definitions

  • the invention relates to a brush for gum massage and tooth cleaning, consisting of a bristle holder with Handle and attached to the bristle holder individually or in bundles Bristles made of plastic.
  • Oral hygiene today not only includes tooth cleaning, but also the gum massage Prevention of gingivitis, periodontal disease, etc. Toothbrushes usual type, whether manually or electrically driven, do the job of cleaning teeth sufficiently, but not that of the gum massage, in particular if both effects on a single trajectory should be achieved. So for teeth cleaning, especially the interdental spaces, the bristle ends particularly effective, but often for gum massage too aggressive, especially if they are not working properly are rounded or flattened by use. For the gum massage, however, the pressure should be and the trajectory are chosen so that the Fold bristles and with their outer surface a kind Effect stroke massage. But they are in this position in turn, far less effective and for tooth cleaning even unsuitable for cleaning the interdental spaces.
  • Toothbrushes are also known in practice Bristle trim in the different directions Brushing the teeth and massaging the gums adapted is. Such a toothbrush has one in comparison hard medium trimmings and more flexible outdoors Massage bristles on. This is inevitable to a compromise, the allocation of different Bristle areas to the treatment areas assigned to them -Tooth or gums- by the user is not easily possible. In addition, this compromise each by reducing the one effect Cost of the other closed.
  • a known toothbrush follows this principle (DE-U-295 01 338), in addition to the usual straight bristles Pole threads are attached to the bristle holder. Are pile threads flaccid textile fibers that go through with this toothbrush thermal shrinkage are curled. These pile threads cannot develop a cleaning effect like bristles.
  • the invention has for its object a brush for Propose gum massage that equally effectively doing teeth cleaning.
  • the bristle designed according to the invention like any other conventional bristle has a rounded working end that equally for cleaning teeth and for gum massage - acts as a kind of massage finger.
  • the unavoidable transfer of the Bristle the wart-like crest in a similar way Wise act like the bristle ends, both at teeth cleaning, as well as gum massage.
  • the bristles are in two or more levels corrugated, which ensures that regardless of how the bristle turns when cleaning, wart-like crests always come into effect.
  • the effect of the bristles designed according to the invention can also be determined by the geometry of the individual shaft influence.
  • the wavelength can be 1 to 10 times the bristle diameter, but is advantageously between 1 and 5 times. In In a preferred embodiment, the wavelength is smaller than twice the bristle diameter.
  • the wave height i.e. the distance opposite Wave crest, be as small as possible. Preferably it is 1.2 to 2 times the bristle diameter.
  • the shape of the crest of the wave is from Meaning, with angular wave crests are preferred over rounded ones.
  • wire brushes and brushes that to use used wire pins, but stand here Reasons for stability and the abrasive effect in the foreground (US 1 178 179, DE-U-79 06 716).
  • hairpin bristles known (US 2,511,004), which consist of plastic, however in their natural bristle form if possible should come close. These bristles are profiled with long waves and pointed at their ends. You are in the first Line designed for paintbrushes and paintbrushes. The production this bristle is made in that starting from an endless monofilament of this at regular intervals is constricted by tensile forces. Then be cut the bristles, each in the area the constriction so that a single bristle with two tapered ends is formed.
  • the invention has for its object a method for the production of the bristles designed according to the invention to propose, in which the aforementioned disadvantages are avoided become.
  • the method according to the invention is therefore distinguished characterized in that a continuous plastic monofilament through the Form rollers passed through and behind the form rollers a spool is wound, the monofilament with Relative to its axis by the coils against rotation is held, and that the bristles by cutting the wavy endless monofilament.
  • the endless monofilament is preferably made by means of the forming rolls withdrawn from a spool. Instead it is also possible to create the endless monofilament in to feed the form rolls to an extruder. The curl takes place without additional heat from the outside.
  • the monofilament is preferably between at least two with the smallest possible distance immediately behind one another Form roller pairs passed to the to form a pronounced wave crest irreversibly.
  • Figure 1 is a brush for gum massage and Dental cleaning shown, which consists of a handle 1, a Bristle holder serving head 2 and a variety individually standing bristles 3 is formed.
  • the bristles 3 can possibly also combined into bundles or packages his. All or part of the bristles are included short wavelength wavy.
  • Your usage ends 4 can, as in the embodiment shown, the Following the waveform be bent out of the bristle axis.
  • Figure 3 is a bristle 3 during use of the Brush shown on an enlarged scale. It can be seen like the wart-like crests of the kind of Apply massage nubs to the gums.
  • Figure 4 shows an enlarged partial view of a bristle 3, which is corrugated evenly sinusoidal, so that wart-like Wave crests 5 and troughs 6 arise. While the wave apex 5 the effective work surfaces form the bristle, the troughs take 6 dentifrices or the like.
  • the bristle according to Figure 4 can Have cross section according to Figure 5, that is, two perpendicular planes facing each other must be corrugated so that wart-like crests on the surface of the bristle 5 extend in the direction of all four coordinates.
  • Figure 6 is a bristle with a modified wave shape shown.
  • the wave edges run essentially straight and the wart-like crests 5 point a much smaller radius of curvature.
  • At this embodiment corresponds approximately to the wavelength the bristle diameter, as indicated by the letter "D".
  • Figure 7 shows a bristle similar to Figure 4 with a Wavelength about twice the bristle diameter corresponds.
  • Figure 8 in turn shows a bristle with relative elongated shaft and straight flanks 7 and even more pronounced wave crests 5 with whole small radius of curvature. The wavelength is at this bristle is about 4 times the bristle diameter.
  • Figures 13 and 14 is a device for performing of the method according to the invention schematically indicated. It has a supply spool 10 on which an endless monofilament 11 made of plastic is wound up. Further it has a collecting coil 12 for receiving the corrugated Monofilament 13.
  • the monofilament 11 runs through three in a row arranged form rollers or pairs of form rollers 14, 15 and 16, the extent of which corresponds to the desired Waveform ( Figures 4 to 8) are profiled.
