Description
- This application is a U.S. National Phase Application of International Application PCT/EP2014/001200 filed May 6, 2014 and claims the benefit of priority under 35 U.S.C. §119 of
German Patent Application 10 2013 007 870.9 filed May 8, 2013, the entire contents of which are incorporated herein by reference. - The present invention pertains to a plastic monofilament and to a toothbrush bristle manufactured from a corresponding monofilament.
- The cleaning action of a bristle depends essentially on the geometry of the individual bristles and the material of which the bristles consist. In particular, it 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 formed integrally at their radially inner end with a core forming the matrix, are known from EP 0 850 004 B1 or EP 0 874 925 B1. The core and the rib may consist of different plastics in order to adapt the strength and bending properties of the bristle, on the one hand, and the cleaning action by the rib to the desired intended use, on the other hand If the bristle is used in a toothbrush, it shall, moreover, be ensured by selecting the material that the user cannot be injured.
- It was found that the selection of the material for the rib, on the one hand, and for the matrix, on the other hand, is greatly limited by the need for the two materials to become connected to one another during the manufacture of the corresponding monofilament in order to prevent the rib from becoming separated from the matrix during the use of the bristle. This limitation in selecting the material is highly disadvantageous, so that an optimized cleaning action can rarely be achieved.
- A basic object of the present invention is to create a monofilament for manufacturing a bristle or a toothbrush bristle manufactured therefrom, in which the possibilities of selecting and combining the materials for the rib and the matrix are improved.
- This object is accomplished according to the present invention by a monofilament comprising a matrix of a first plastic material at least in a first area and at least one rib, which extends in the longitudinal direction of the monofilament and which is comprised of a second plastic material and which is held in the first area of the matrix in a positive-locking manner.
- Based on the positive-locking connection between the rib and the first area of the matrix, secure holding of the rib in the matrix can be achieved independently from whether or not there is additionally a connection in substance and/or a non-positive connection between the first plastic material of the first area of the matrix and the second plastic material of the rib. It is possible, on the one hand, to hold the rib solely via positive-locking connection in the first area of the matrix, but it is also possible, as an alternative, to additionally provide especially a connection in substance or a non-positive connection between said materials. In a preferred embodiment of the present invention, the materials and the parameters with which the monofilament is extruded are selected to be such that the rib is also welded to the first area of the matrix in addition to the positive-locking connection. As an alternative or in addition hereto, provisions may, however, also be made for the rib to be bonded to the first area of the matrix in addition to the positive-locking connection.
- Provisions are made in a possible embodiment of the present invention for the rib to have a radially outwardly tapering cross section, for example, a triangular or drop-shaped cross section, so that it tapers to a tip in its radially outer cross-sectional area.
- To guarantee good positive-locking connection between the rib and the first area of the matrix, the rib should be provided with undercuts at its radially inner end area embedded into the first area of the matrix. Provisions are preferably made for a broadened foot, around which the first plastic material of the first area of the matrix extends, to be provided in the radially inner end area of the rib.
- Depending on the field of use, the monofilament may have a single rib or a plurality of ribs, and the ribs should be preferably distributed uniformly over the circumference of the monofilament in case a plurality of ribs are arranged.
- The rib or ribs may also extend straight axially parallel in the longitudinal direction of the monofilament, but it is also possible that the ribs extend around the matrix in the manner of a coil. This can be achieved especially if the monofilament is twisted in the known manner after the extrusion. The twisting is preferably performed at 50 to 400 revolutions per running meter.
- Provisions may be made in a possible embodiment of the present invention for the first area to form the entire matrix, i.e., the matrix consists exclusively of the first plastic material, in which the rib or ribs is/are held in a positive-locking manner.
- As an alternative, provisions may be made for the first area of the matrix to have a ring-shaped cross section and to surround at least an inner, second area of the matrix, which area consists of a third plastic material. The use properties of the monofilament or of the bristle manufactured from same can be adapted in this manner even better to the desired intended use.
- To strengthen the holding of the ribs in the matrix, provisions may be made in a variant of the present invention for the ribs to be connected to one another by means of the inner, second area of the matrix.
- The plastic materials may be selected extensively freely based on the positive-locking connection. Provisions may be made in a first possible embodiment for the first plastic material of the first area of the matrix to be a rigid thermoplastic polyester and especially PBT (polybutylene terephthalate). However, provisions may also be made, as an alternative, for the first plastic material of the first area of the matrix to be a soft thermoplastic plastic and especially a thermoplastic elastomer.
- The second plastic material of the rib may also be a rigid thermoplastic polyester and especially PBT (polybutylene terephthalate) or a soft thermoplastic plastic and especially a thermoplastic elastomer.
- The third plastic material of the inner, second area of the matrix may be selected freely within broad limits. If the ribs are connected to one another at their radially inner ends by means of the second area of the matrix, provisions are preferably made for the third plastic material of the second area of the matrix to be identical to the second plastic material of the ribs.
- Provisions are made in a preferred embodiment of the present invention for at least one rib to be dyed and to be distinguished thereby in color from the rest of the monofilament. It is possible in this manner to visualize to the user the fact that the monofilament is twisted in order to thereby avoid confusion in the use of the monofilament.
- Bristles, which are preferably used as toothbrush bristle, can be manufactured from the monofilament according to the present invention in the usual manner.
- Further details and features of the present invention can be found in the following description of exemplary embodiments with reference to the drawings. The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference is made to the accompanying drawings and descriptive matter in which preferred embodiments of the invention are illustrated.
