Definitions

  • the invention relates to a brush, in particular an interdental brush, comprising a plurality of fibers. Bristles that are fixed radially projecting between two wire-like sections by twisting them.
  • the wire-like sections consist of a metal wire or of a metal wire coated with plastic (see for example document GB-A-2 085 718).
  • the wire breaks off the twisted wire sections, the user can be injured in the mouth and throat area during use and there is a risk of broken pieces being swallowed.
  • the fiber sections that protrude radially are held by the clamping tension of the twisted wire and can come loose. These loose fiber sections can either be in the interdental spaces or gaps getting caught or getting caught, which is very uncomfortable.
  • the wire sections conventionally used can cause galvanic effects when these wires come into contact with tooth fillings. Even with a plastic coating, such effects cannot be completely avoided, since the plastic coating can receive cracks during the manufacturing process or during further processing, which are not mechanically large, but are at least sufficient to enable a certain electrical conductivity in connection with the mouth saliva and to make unpleasant galvanic reactions noticeable.
  • the object of the invention is to further develop a brush of the type in question in such a way that the usage properties and the dental care properties are further improved.
  • the wire-like sections consist of at least one plastic fiber.
  • plastic fibers with a suitable selection, can have very similar properties with regard to their twisting behavior as are known from conventionally used wires, i.e. the twisted plastic fiber sections remain in the twisted state without unscrewing again, so that they are able to hold the fibers or bristles or bundles of fibers or bristles in between in such a way that they protrude radially outward.
  • Polyamide, polyacrylic, polypropylene, polyester, polycarbonate, PBT, PEEK and plastic fiber, which are reinforced with the aid of glass fibers or spherulites or the like, are preferably suitable as plastics for the fiber sections to be twisted here.
  • the cross section of the plastic fiber is between 0.025 and 1.5 mm.
  • Fillers can also be added to the fibers, e.g. Glass fibers or talc.
  • These fillers can also include abrasive materials such as silicon carbide or the like.
  • abrasive materials such as silicon carbide or the like.
  • Such fibers are known as such from abrasive brushes, and in addition to silicon carbide, the more resistant aluminum oxide also comes into consideration.
  • Teynex which contain silicon carbide with grain sizes between 46 and 500 and aluminum oxide with grain sizes between 80 and 500 with a grain content of 30%.
  • brushes designed in this way have the advantage that, both when new and when used for a long time, it is absolutely ensured that the brush's core, which is made of all-plastic, does not cause any galvanic effect that the radially projecting bristles are held reliably , and that by the fillers for the twisted fibers an additional effect, for example an abrasive effect can be achieved.
  • the resilience and the rigidity of the plastic can also be adjusted, so that the twisted fibers can be adjusted in such a way that they behave similarly to a conventionally used metal wire.
  • the behavior of the fibers can also be controlled by selecting the cross-section and the cross-sectional geometry.
  • the radially projecting fibers can be selected so that they spread out under mechanical or chemical influences, so that after twisting, fiber bundles can be created from relatively fine fibers.
  • the radially projecting fibers are corrugated, for example in order to achieve a statistical distribution of the fiber tips along the circumference in this way.

Abstract

L'invention concerne une petite brosse, notamment une petite brosse interdentaire qui comprend une pluralité de fibres ou de poils (5) fixés en saillie dans le sens radial, entre deux sections (1, 2) se présentant sous forme de fils, par torsion desdites sections (1, 2). Afin d'améliorer les propriétés de manipulation et d'hygiène bucco-dentaire de cette petite brosse, il est prévu que les sections (1, 2) se présentant sous forme de fils soient constituées d'au moins une fibre plastique (3).

Claims (7)

  1. Petite brosse, notamment petite brosse interdentaire comprenant, respectivement, une pluralité de fibres ou de soies qui sont fixées en place avec saillie radiale entre deux segments du type fils métalliques, par torsade de ces derniers, caractérisée par le fait que les segments (1, 2) du type fils métalliques consistent en au moins une fibre de matière plastique (3).
  2. Petite brosse selon la revendication 1, caractérisée par le fait que la section transversale de la fibre (3) est comprise entre 0,025 et 1,5 mm.
  3. Petite brosse selon la revendication 1, caractérisée par le fait que des substances de charge sont ajoutées aux fibres (3).
  4. Petite brosse selon la revendication 3, caractérisée par le fait que les substances de charge renferment des substances abrasives, telles que du carbure de silicium ou matières similaires.
  5. Petite brosse selon la revendication 3, caractérisée par le fait que les substances de charge sont sélectionnées de manière à accroître la rigidité.
  6. Petite brosse selon la revendication 1, caractérisée par le fait que les fibres (1, 2) saillant radialement sont réalisées sous la forme de libres expansibles, accusant une expansion sous des influences mécaniques ou chimiques.
  7. Petite brosse selon la revendication 1, caractérisée par le fait que les libres (1, 2) saillant radialement sont ondulées.
