Definitions

  • the invention relates to a toothbrush with a brush head made of plastic and standing individually in the brush head embedded plastic bristles with little Are spaced from each other.
  • Toothbrushes of this construction are known (WO 96/27 308). Compared to conventional toothbrushes where the bristles combined into individual bundles and several Bundles are attached to the brush head, have the aforementioned Toothbrushes have the advantage that at Cleaning primarily effective bristle ends on the effective brush surface are evenly distributed so that with the dentist-recommended cleaning method of red according to white, that is, an essentially vertical guide the brush with a superimposed slight swiveling movement the entire area covered by the bristle trim is cleaned (teeth) or massaged (gums), while toothbrushes with the usual bundle certain areas of the tooth flesh and / or teeth untreated stay.
  • the nursing or Cleaning condition of the molars especially on the Outside of the dentition (distal) much worse than in the anterior region.
  • This is related to the essential poor accessibility of the molars, the often cramped conditions in the distal space, which at Anomalies in dentition serious forms can assume, and that in the distal area of the molars Often increased sensitivity and irritability ever after guiding the toothbrush to the point of nausea can.
  • the dental cleaning method recommended red / white can be seen in the molar area because of the cramped Carry out conditions insufficiently. by virtue of the greater pressure load occurs in this area also more likely to injuries to the gums and Enamel lesions.
  • the invention has for its object a toothbrush to create a perfect even in the molar area
  • this object is achieved according to the invention in that about 400 to 800 individual bristles per cm 2 are arranged on the brush head on the area provided with bristles and which result from the free length of the individual bristles and the thickness of the brush head, the overall height of the toothbrush is between 6.5 and 11 mm.
  • the toothbrush designed according to the invention stands out initially due to an extremely low overall height free bristle length and thickness of the brush head formed is out. It is between 6.5 and 11mm while it with conventional toothbrushes up to 20mm is sufficient. by virtue of This flat design is also the distal area of the molars can be easily cleaned there red / white method can be applied and the proof to be determined exclusively by the user, since the No more pressure on the toothbrush on the inside of the cheek exercises. Due to the number of individual bristles standing at a short distance can be the bending stiffness despite the shorter length of the Set the individual bristles to the desired size or user-specific ablacen.
  • the training according to the invention is both for manual guided toothbrushes, so one on the brush head have attached handle, as well as for electrical powered toothbrushes where the brush head is on a drive is attached with the same effects used.
  • the free length of the individual bristles is preferably between 5 and 9.5mm and the thickness of the brush head between 1.5 and 3.0mm.
  • the small thickness of the brush head is particularly possible in that the individual bristles to achieve the necessary pull-out strength only a short length in the plastic of the brush head must be embedded.
  • the training according to the invention also allows the to give effective brushing surface a topography, in the free ends of the individual bristles on a steady or discontinuously curved envelope surface, their distance varies from the surface of the brush head by up to 3mm.
  • Another variation option for bending stiffness results from the fact that the diameter of the individual bristles is between 0.095 and 0.225mm and the selected one effective diameter, the smaller the smaller the free length of the individual bristles.
  • a preferred embodiment of the toothbrush according to the invention is characterized in that the overall height of the toothbrush is approximately 8.5 mm with a free length of the individual bristles of 7 mm and a thickness of the brush head of 1.5 mm, approximately 600 bristles per cm 2 being provided ,
  • the training according to the invention also gives the possibility that the brush head on its bristle side has convex surface and the individual bristles are arranged approximately perpendicular to the surface.
  • the ends of the bristles lie if they have the same length, on a corresponding one convex envelope surface. This enables at red / white method in which the toothbrush is usually light is pivoted, a better attack of the bristle ends.
  • Convention bundle toothbrushes you have that tries to achieve the same effect in that the Bundle only in the longitudinal central axis of the brush head inclined perpendicular to the surface and outwards be ordered with a simultaneous reduction in the outer bundle. But due to the inclination the brushing and cleaning effect of the individual bundles differently. In addition, due to the sloping Bristle the risk that they are against the direction of cleaning flip and then look like skewers.
  • the convex formation the brush head in the context of the invention is without appreciable increase in height due to the low Thickness of the brush head possible.
  • the back of the brush head can also be used be concave so that the brush head has approximately the same thickness over its entire length, without the brush head sticking through this profile becomes.
  • the point perpendicular to the Surface standing individual bristles preferably the same Length on.
  • the embedding length of the attachment-side ends of the Single bristle is preferably less than 10 times of the diameter of the bristle.
  • the embedding length is So with the above Diameter range from 0.125 to 0.225mm at a maximum of 1.25 to 2.25mm.
  • Figures 1 and 2 is one for manual use certain toothbrush 1 shown. It has a stem 2, a preferably flexible neck 3 and a brush head 4 with 5 bristles.
  • the bristle trim 5 consists of individually standing and with a small distance bristles arranged from each other, as can be seen from the figures 3 and 4 results.
  • the individual bristles 6 are with their Anchored ends 7 in the brush head 4. For example have the individual bristles at their ends 7 by melting the same obtained thickenings 8, by means of by molding them with the plastic of the brush head 4 are anchored in this.
  • the bristles 6 have a diameter between 0.095 and 0.225mm and a free length "1" from 5 to 9.5mm.
  • the overall height of the toothbrush in the area of the brush head is between 6.5 and 11mm, the thickness "d" the brush head is between 1.5 and 3.0 mm.
  • the depth of embedding "a" of the individual bristles is between 0.2 and 0.8mm, preferably about 0.4mm.
  • the distance of the Individual bristles 6 among one another are preferably selected that there are about 600 bristles on a square centimeter are located.
  • the brush head arched in cross section so that the ends of the Individual bristles 6 on a correspondingly curved envelope surface lie.
  • This envelope can be different Lengths of the individual bristles 6 also corrugated or stepped his.
  • the individual bristles are perpendicular to Surface of the brush head 4.
