Description

Monofil aus Kunststoff und Zahnbürsten-Borste aus einem entsprechenden Monofil  Monofilament of plastic and toothbrush bristle of a corresponding monofilament
Die Erfindung betrifft ein Monofil aus Kunststoff und eine aus einem entsprechenden Monofil hergestellte Zahnbürsten- Borste . The invention relates to a plastic monofilament and a toothbrush bristle made from a corresponding monofilament.
Die Reinigungswirkung einer Bürste ist wesentlich von der Geometrie der einzelnen Borsten und dem Material abhängig, aus dem die Borsten bestehen. Insbesondere hat es sich als vorteilhaft erwiesen, die Borsten auf ihrer Mantelfläche zu strukturieren oder zu profilieren, so dass die Borsten eine Schabewirkung haben. 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.
Aus der EP 0 850 004 Bl oder der EP 0 874 925 Bl sind jeweils Borsten bekannt, die mehrere achsparallele Rippen aufweisen, die an ihrem radial inneren Ende an einem die Matrix bildenden Kern angeformt sind. Dabei können der Kern und die Rippe aus unterschiedlichen Kunststoffen bestehen, um einerseits die Festigkeits- und Biegeeigenschaft der Borste und andererseits die Reinigungswirkung durch die Rippe an den gewünschten Einsatzzweck anzupassen. Wenn die Borste bei einer Zahnbürste verwendet wird, ist darüber hinaus durch die Materialwahl sicherzustellen, dass der Benutzer sich nicht verletzten kann. From EP 0 850 004 B1 or EP 0 874 925 B1, respectively bristles are known, which have a plurality of axially parallel ribs, which are integrally formed at their radially inner end on a core forming the matrix. In this case, 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. In addition, if the bristle is used on a toothbrush, the choice of materials should ensure that the user can not be injured.
BESTÄTIGUNGSKOPIE Es hat sich herausgestellt, dass die Materialauswahl einerseits für die Rippe und andererseits für die Matrix dadurch stark beschränkt ist, dass die beiden Materialien bei der Herstellung des entsprechenden Monofils eine starke Verbindung eingehen müssen, um zu verhindern, dass sich die Rippe bei Benutzung der Borste von der Matrix löst. Diese Beschränkung in der Materialwahl ist sehr nachteilig, so dass eine optimierte Reinigungswirkung selten erreicht werden kann. CONFIRMATION COPY It has been found that the material selection on the one hand for the rib and on the other hand for the matrix is strongly limited by the fact that the two materials must make a strong connection in the production of the corresponding monofilament, in order to prevent the rib from using the bristle detached from the matrix. This restriction in the choice of material is very disadvantageous, so that an optimized cleaning effect can rarely be achieved.
Der Erfindung liegt die Aufgabe zugrunde, ein Monofil zur Herstellung einer Borste bzw. eine daraus hergestellte Zahnbürsten-Borste zu schaffen, bei dem für das Material der Rippe und der Matrix verbesserte Auswahl- und 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

Es ist einerseits möglich, die Rippe allein über Due to the positive connection between the rib and the first area of the matrix, secure retention of the rib in the matrix can be achieved independently of whether between the 1st plastic material of the first area of the matrix and the second plastic material of the rib in addition, a cohesive and / or non-positive connection is given. It is possible on the one hand, the rib alone over
