Definitions
- the invention relates to a plastic monofilament and a toothbrush bristle made from a corresponding monofilament.
- the cleaning effect of a brush depends essentially on the geometry of the individual bristles and the material of which the bristles are made. In particular, it has proved to be advantageous to structure or profile the bristles on their lateral surface so that the bristles have a scraping action.
- bristles which have a plurality of axially parallel ribs, which are integrally formed at their radially inner end on a core forming the matrix.
- the core and the rib may be made of different plastics, on the one hand to adapt the strength and bending property of the bristle and on the other hand, the cleaning effect by the rib to the desired application.
- the bristle is used on a toothbrush, the choice of materials should ensure that the user can not be injured.
- the invention has for its object to provide a monofilament for producing a bristle or a toothbrush bristle produced therefrom, in which for the material of the rib and the matrix improved selection and
- the monofilament has a matrix which consists of a plastic material at least in a first region and at least one in
- the materials and the parameters in the extrusion of the monofilament are chosen so that the rib is also welded to the first region of the matrix in addition to the positive connection.
- the materials and the parameters in the extrusion of the monofilament are chosen so that the rib is also welded to the first region of the matrix in addition to the positive connection.
- Form-fitting is glued.
- the rib has a radially outwardly tapering cross-section, for example a triangular or drop-shaped cross-section, so that it tapers in its radially outer cross-sectional area.
- the rib In order to ensure a good positive connection between the rib and the first region of the matrix, the rib should be provided with undercuts at its radially inner end region embedded in the first region of the matrix. It is preferably provided that in the radially inner end region of the rib a common foot
- the monofilament may have a single rib or a plurality of ribs, and if several ribs are arranged, they should preferably be distributed equally over the U of the monofilament.
- the rib or ribs can become straight
- the ribs in the form of a Spiral around the matrix can be achieved in particular if the monofilament is twisted after the extrusion in a manner known per se. Preferably, the twisting is done with 50 to 400 revolutions per meter.
- the 1st area forms the entire matrix, i. the matrix consists solely of the 1st plastic material in which the rib or ribs
- the first area of the matrix has an annular cross-section and
- the ribs are connected to one another by means of the inner, second region of the matrix.
- the plastic materials can be chosen largely freely due to the positive connection.
- the 1st plastic material of the first region of the matrix is a rigid one
- thermoplastic polyester and in particular PBT
- the first plastic material of the first region of the matrix is a soft thermoplastic Plastic and in particular a thermoplastic elastomer.
- the second plastic material of the rib can also be a rigid thermoplastic polyester and in particular PBT
- thermoplastic plastic and in particular a
- thermoplastic elastomer be thermoplastic elastomer
- Range of the matrix can be freely selected within wide limits. If the ribs are connected together at their radially inner ends by means of the second region of the matrix, it is preferably provided that the third plastic material of the second region of the matrix is equal to the second plastic material of the ribs.
- bristles can be prepared in the usual way, preferably as
- Toothbrush bristle find use.
- Fig. 2 shows a modification of the embodiment according to FIG.
- Fig. 3 shows the cross section of a second embodiment of the monofilament
- Fig. 4 shows a modification of the embodiment according to FIG.
- FIG. 1 shows a cross-section through a plastic monofilament 10 which has a matrix 11 consisting of a first area 13 with a circular cross-section made entirely of a first plastic material
- the monofilament 10 has three ribs 12 projecting longitudinally, i.e. perpendicular to the plane of the drawing, on the outside radially from the matrix 11.
- Each rib 12 has a triangular, radially outward
- the second plastic material of the ribs 12 is a soft thermoplastic.
- the ribs 12 may be held in the matrix 11 by means of gluing or welding in addition to the positive locking.
- Figure 2 shows a figure 1 similar embodiment and differs from this only in that in the radially inner end region of the ribs 12 each have a common foot 15 is provided, which is the over the
- FIG. 3 shows a further exemplary embodiment of the invention
- the monofilament 10 according to the invention has a first region 13 made of a first plastic material which has an annular cross-section. Within the 1.
- annular region 13 a second region 14 of the matrix is arranged, which consists of a third plastic material.
- the ribs 12 are in a form-fitting manner in the
- annular first area 13 of the matrix 11 are located with their radially inner ends on the inside
- the ribs 12 are connected to the inner second region 14 of the matrix 11 by gluing or welding.
- FIG. 4 shows a design corresponding to the exemplary embodiment according to FIG. 3, which only differs therefrom in that the ribs 12 and the inner second region 14 of the matrix consist of a uniform material and are formed as a monolithic body.
