Definitions
- the invention relates to a brush, in particular an interdental brush, comprising a plurality of fibers. Bristles which 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.
- 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 interdental spaces or gaps get caught or get 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 cracks are not mechanically large, but are at least sufficient to combine a certain electrical conductivity with the mouth saliva and to make unpleasant galvanic reactions palpable.
- the object of the invention is to develop a brush of the type in question in such a way that the use 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 themselves 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 .
- Suitable plastics for the fiber sections to be twisted here are preferably polyamide, polyacrylic, polypropylene, polyester, polycarbonate, PBT, PEEK and plastic fiber, which are reinforced with the aid of glass fibers or spherulites or the like.
- the cross section of the plastic fiber is between 0.025 and 1.5 mm.
- Fillers can also be added to the fibers, for example 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 solid plastic, has no galvanic effect whatsoever, that the radially projecting bristles are reliable are kept, and that the fillers for the twisted fibers have an additional effect, for example an abrasive effect can be achieved.
- the resilience and the rigidity of the plastic can also be adjusted with the aid of fillers, 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.
- Fig. 1 is a schematic side view of a brush according to the invention and Fig. 2 is a side view before twisting the fiber sections.
