Description

Bürste und Verfahren zur Herstellung einer Bürste  Brush and method of making a brush
Die Erfindung bezieht sich auf eine Bürste mit einem Bürsten- körper und mit an einem Borstenträger gehaltenen Borstenbündeln sowie auf ein Verfahren zu deren Herstellung. Bei der Herstellung von Bürsten, bei denen die Borsten nicht in den Bürstenkörper eingestopft, sondern die Borstenbündel im Bereich des Bürstenkörpers von dem Kunststoffmaterial umspritzt und so an dem Bürstenkörper gehalten sind, besteht das Problem, dass beim Spritzen des Bürstenkörpers durch den hohen Spritz- druck flüssiges Kunststoffmaterial durch die einzelnen Filamente der Borstenbündel oder am Bündelrand hochgedrückt wird und dieses überschüssige Kunststoffmaterial dann an der Bürstenoberfläche sichtbar ist und die Bürste so unbrauchbar ist. Um dieses Problem zu lösen, kennt man bereits verschiedene Vorrichtungen und Verfahren. Aus der EP 1 110 478 A1 ist ein Verfahren bekannt, bei dem die in ein Formnest hineinragenden Enden von Borstenbündeln zunächst mit einer Kunststoffkomponente umspritzt werden und der so gebildete Borstenträger dann in ein weiteres Formnest umgesetzt wird, in welchem der Bürstenkörper gespritzt und dabei der Borstenträger umspritzt wird, der so ein Teil des Bürstenkörpers wird. Der Borstenträger kann dabei mit geringem Spritzdruck gespritzt werden, so dass ein Überquellen des Spritzmaterials im Bereich der Borstenbündel ver- mieden werden kann. The invention relates to a brush with a brush body and held on a bristle carrier bristle bundles and to a method for their preparation. In the manufacture of brushes, in which the bristles are not stuffed into the brush body, but the bristle bundles in the brush body around the plastic material and thus held on the brush body, there is the problem that when spraying the brush body by the high injection pressure liquid plastic material is pushed up by the individual filaments of the bristle bundles or at the bundle edge and this excess plastic material is then visible on the brush surface and the brush is so useless. To solve this problem, various devices and methods are already known. From EP 1 110 478 A1 a method is known in which the projecting into a mold cavity ends of bristle bundles are first encapsulated with a plastic component and the bristle carrier thus formed is then converted into a further mold cavity, in which the brush body injected and thereby the bristle carrier is overmolded, which is such a part of the brush body. The bristle carrier can be sprayed with a low injection pressure so that overflow of the spray material in the region of the bristle bundles can be avoided.
Problematisch bei diesen wie auch bei herkömmlichen Bürsten, bei denen die Borsten direkt in den Bürstenkörper eingestopft werden, ist jedoch, dass zwischen den Borstenbündeln und dem The problem with these as well as conventional brushes, in which the bristles are stuffed directly into the brush body, however, is that between the bristle bundles and the
BESTÄTIGUNGSKOPIE Bürstenkörper eine starre Verbindung besteht und sich die Borstenbündel bei der Benutzung nicht der zu bearbeitenden Oberfläche anpassen können, was insbesondere bei Zahnbürsten jedoch vorteilhaft wäre. CONFIRMATION COPY Brush body is a rigid connection and the bundles of bristles in use can not adapt to the surface to be processed, which would be particularly advantageous in toothbrushes.
Es besteht daher die Aufgabe, eine Bürste sowie ein Verfahren zu deren Herstellung zu schaffen, deren Borstenbündel sich flexibler an die mit der Bürste bearbeitete Oberfläche anpassen können und/oder bei der eine einfache Herstellung unterschied- licher Bürsten möglich ist. It is therefore an object to provide a brush and a method for the production thereof, whose bristle bundles can adapt more flexibly to the surface treated with the brush and / or in which a simple production of different brushes is possible.
Die erfindungsgemäße Lösung dieser Aufgabe besteht darin, dass die Borstenbündel mit ihrem befestigungsseitigen Ende in dem Borstenträger eingebettet sind und dass zwischen dem Bürsten- körper und dem Borstenträger eine Zwischenschicht aus einer zusätzlichen Material-Komponente vorgesehen ist. The solution to this problem according to the invention consists in that the bundles of bristles are embedded with their fastening-side end in the bristle carrier and that an intermediate layer of an additional material component is provided between the brush body and the bristle carrier.
Es können so unterschiedliche, gegebenenfalls vorgefertigte Borstenträger mit Borstenbündeln einerseits und Bürstenkörper andererseits miteinander verbunden werden, wobei auch durch Va- riation der zusätzlichen Material-Komponente unterschiedliche Bürsten hergestellt werden können, sofern die zusätzliche Material-Komponente an der fertigen Bürste außen sichtbar ist.  It can so different, optionally prefabricated bristle carrier with bristle bundles on the one hand and brush body on the other hand connected to each other, whereby by Variation of the additional material component different brushes can be produced, if the additional material component is visible on the finished brush outside.
Es ist vorteilhaft, wenn die befestigungsseitigen Enden der Borstenbündel von dem Material des Borstenträgers umschlossen sind und der Borstenträger eine die Zwischenschicht und die Borstenbündel auf Abstand haltende Trennschicht bildet. Die zusätzliche Material-Komponente kommt somit beim Einspritzen nicht mit den Borstenbündeln in Kontakt, wodurch Überspritzun- gen im Borstenbereich sicher vermieden sind. Die befestigungsseitigen Enden der Borstenbündel können dabei auch in sich angeschmolzen und die einzelnen Borstenfilamente eines Borstenbündels miteinander verbunden sein. Bevorzugt besteht die Zwischenschicht aus elastischem Material. Dadurch ist der Borstenträger mit den Borstenbündeln elastisch, praktisch "schwimmend", an dem Bürstenkörper befestigt und kann somit, im Falle einer Zahnbürste beim Zähneputzen, ausweichen und sich den Zähnen anpassen, was eine gründlichere und schonendere Reinigung ermöglicht. Für die Borstenbündel ist somit eine Art Federung gebildet. It is advantageous if the fastening-side ends of the bristle bundles are enclosed by the material of the bristle carrier and the bristle carrier forms a separating layer which holds the intermediate layer and the bristle bundles at a distance. The additional material component thus does not come into contact with the bundles of bristles during injection, as a result of which overspraying in the bristle area is reliably avoided. The fastening-side ends of the bristle bundles can also be melted in and the individual bristle filaments of a bundle of bristles can be connected to one another. Preferably, the intermediate layer consists of elastic material. Thus, the bristle carrier with the bristle bundles is elastic, practically "floating", attached to the brush body and thus, in the case of a toothbrush when brushing, dodge and adapt to the teeth, allowing a more thorough and gentle cleaning. For the bristle bundles thus a kind of suspension is formed.
Diese Anpassungsfähigkeit wird zudem unterstützt, wenn der Borstenträger zwischen benachbarten Borstenbündeln Rillen, Vertiefungen oder dergleichen Materialschwächungen aufweist oder wenn der Borstenträger Hülsen zur Aufnahme der einzelnen Borstenbündel aufweist, die über dünnwandige Stege oder dergleichen Materialbrücken miteinander verbunden sind. This adaptability is also assisted when the bristle carrier has grooves, depressions or the like material weakenings between adjacent bundles of bristles or when the bristle carrier has sleeves for receiving the individual bristle bundles which are connected to one another via thin-walled webs or similar material bridges.
Je dünner der Borstenträger selbst ausgebildet ist, desto höher ist auch seine Flexibilität an sich.  The thinner the bristle carrier itself is formed, the higher its flexibility in itself.
Es ist auch möglich, dass mehrere Borstenträger an einem Bürs- tenkörper vorgesehen sind. Mehrere Borstenträger können so zu einem größeren Gesamt-Borstenfeld zusammengestellt werden,- wobei auch unterschiedliche Kombinationen unterschiedlicher Borstenträger möglich sind, um auf einfach Art unterschiedliche Bürsten herstellen zu können. It is also possible for a plurality of bristle carriers to be provided on a brush body. Several bristle carriers can be put together to form a larger overall bristle field, whereby different combinations of different bristle carriers are possible in order to be able to easily produce different brushes.
Es kann zweckmäßig sein, wenn die Zwischenschicht in Querrichtung zur Borstenlängsrichtung zumindest abschnittsweise über den Außenumfang des Bürstenkörpers und/oder des Borstenträgers übersteht. Dadurch ergibt sich ein ganz oder teilweise um den Bürstenkopf umlaufendes Polster, das als Schutz oder als zusätzliches Funktionselement, beispielsweise zur Zungenreinigung, verwendet werden kann. Es können auch zusätzliche Funktionselemente aus der zusätzlichen Materialkomponente vorgesehen sein, die mit der Zwischenschicht verbunden sind. Diese sind dann in einem Spritzvorgang mit der Zwischenschicht herstellbar. It may be expedient if the intermediate layer protrudes in the transverse direction to the longitudinal direction of the bristle at least in sections over the outer circumference of the brush body and / or the bristle carrier. This results in a completely or partially around the brush head circumferential pad, which can be used as protection or as an additional functional element, for example, for tongue cleaning. It may also be provided additional functional elements of the additional material component, which are connected to the intermediate layer. These can then be produced in an injection process with the intermediate layer.
Als zusätzliche Funktionselemente können beispielsweise Massagenoppen, ein Zungenschaber oder ein Schleimhautschutz vorgesehen sein. Beispielsweise können seitlich neben oder zwischen den Borstenbündeln, parallel dazu angeordnete, lamellenartige Noppen vorstehen, mit denen beim Putzen der Zähne das Zahnfleisch massiert werden kann. As additional functional elements, for example massage knobs, a tongue scraper or a mucous membrane protection can be provided. For example, laterally next to or between the bundles of bristles, lamellar knobs arranged parallel to them can protrude, with which the gums can be massaged when brushing the teeth.
Je nach Art der verwendeten Materialien für den Bürstenkörper, den Borstenträger und die Zwischenschicht kann die Zwischenschicht mit dem Bürstenkörper und dem Borstenträger jeweils materialschlüssig verbunden sein. Dabei kann die Zwischenschicht auch als Bindeglied dienen, um zwei unterschiedliche Materialien für den Bürstenkörper und den Borstenträger, die sich nicht direkt miteinander verbinden lassen, zu kombinieren. Depending on the type of materials used for the brush body, the bristle carrier and the intermediate layer, the intermediate layer with the brush body and the bristle carrier may each be connected materially. In this case, the intermediate layer can also serve as a link to combine two different materials for the brush body and the bristle carrier, which can not be directly connected to each other.
Denkbar ist auch, dass die Zwischenschicht mit dem Bürstenkörper und dem Borstenträger jeweils verschweißt oder klebend verbunden ist. It is also conceivable that the intermediate layer is welded or adhesively bonded to the brush body and the bristle carrier in each case.
Es ist vorteilhaft, wenn an dem Borstenträger und/oder dem Bürstenkörper vorstehende Auflageelemente vorgesehen sind. Diese dienen als Abstandhalter beim Herstellen der Bürste. Ein Element (Borstenträger oder Bürstenkörper) stützt sich an den Auflageelementen des jeweils anderen Elements ab. Dadurch ist eine definierte Lage mit korrektem Abstand der beiden Elemente zueinander sichergestellt. It is advantageous if projecting support elements are provided on the bristle carrier and / or the brush body. These serve as spacers in the manufacture of the brush. One element (bristle carrier or brush body) is supported on the support elements of the other element. This ensures a defined position with correct spacing between the two elements.
Die Auflageelemente können spitz zulaufend ausgebildet sein. Je nach Härtegrad der Auflageelemente werden beim Zusammensetzen von Borstenträger und Bürstenkörper die freien Enden abgetragen oder in das jeweils andere Element eingedrückt. Dies bewirkt einerseits einen guten Halt der beiden Elemente aneinander, was insbesondere dann vorteilhaft sein kann, wenn die Elemente vorgefertigt wurden und erst beispielsweise nach mehrtägiger Lagerung, bei der sich leichte Verformungen ergeben können, miteinander verbunden werden. Andererseits entsteht eine Spannung, die den Bürstenkörper und den Borstenträger gegen die Formflächen der Spritzform beim Spritzen der zusätzlichen Materialkomponente drückt, wodurch eine präzise Positionierung der Elemente sichergestellt ist. The support elements may be formed tapering. ever according to the degree of hardness of the support elements, the free ends are removed during assembly of bristle carrier and brush body or pressed into the other element. This causes on the one hand a good hold of the two elements together, which can be particularly advantageous if the elements were prefabricated and only after several days of storage, in which slight deformations may result, are connected to each other. On the other hand, creates a tension that presses the brush body and the bristle carrier against the mold surfaces of the mold during injection of the additional material component, whereby a precise positioning of the elements is ensured.
Es ist auch möglich, dass die freien Enden der Auflageelemente des Borstenträgers jeweils in eine Aufnahme des Bürstenkörpers und/oder die freien Enden der Auflageelemente des Bürstenkörpers jeweils in eine Aufnahme des Borstenträgers eingreifen. Dadurch können beispielsweise bei Bürstenköpfen für elektrische Zahnbürsten die hohen Winkelbeschleunigungen zwischen Bürstenkörper und Borstenträger besser übertragen werden. It is also possible that the free ends of the support elements of the bristle carrier in each case engage in a receptacle of the brush body and / or the free ends of the support elements of the brush body in each case in a receptacle of the bristle carrier. As a result, for example, in the case of brush heads for electric toothbrushes, the high angular accelerations between brush body and bristle carrier can be transmitted better.
Dabei können die Aufnahmen des Borstenträgers und/oder des Bürstenkörpers jeweils eine Hinterschneidung und die freien Enden der Auflageelemente jeweils eine entsprechende Gegenprofi- lierung aufweisen. Dies hat den Vorteil, dass Bürstenkörper und Borstenträger bereits außerhalb der Spritzform für die zusätzliche Material-Komponente zusammengefügt und dann gemeinsam in die Spritzform eingesetzt werden können, was insbesondere bei größeren Bürsten, wie Handwaschbürsten, Spülbürsten oder Besen zweckmäßig ist. In this case, the receptacles of the bristle carrier and / or of the brush body can each have an undercut and the free ends of the support elements each have a corresponding counterprofiling. This has the advantage that brush body and bristle carrier can already be assembled outside of the mold for the additional material component and then used together in the mold, which is particularly useful for larger brushes, such as hand brushes, dishwashing brushes or brooms.
Die Borstenbündel können insbesondere durch Umspritzen ihrer angeschmolzenen Befestigungsenden mit dem Borstenträger, der durch die Umspritzung gebildet wird, verbunden werden. Es ist jedoch auch möglich, dass die Borstenbündel in einen Bündelaufnahmelöcher aufweisenden Borstenträger mit Ankerschlingen oder Ankerplättchen eingestopft werden. Denkbar ist auch ein Ankle- ben oder Anschweißen der Borstenbündel an einen vorgefertigten Borstenträger . The bristle bundles can in particular by encapsulation of their fused mounting ends with the bristle carrier, the is formed by the encapsulation, are connected. However, it is also possible that the bristle bundles are stuffed into a bundle receiving holes having bristle carrier with anchor loops or anchor plate. It is also conceivable gluing or welding the bristle bundles to a prefabricated bristle carrier.
Hinsichtlich des Verfahrens ist die Erfindung dadurch gekennzeichnet, dass zwischen den Bürstenkörper und den Borstenträger eine zusätzliche Material-Komponente als Verbindungsmittel eingebracht wird. Dadurch ergeben sich für die fertige Bürste die bereits zuvor erläuterten Vorteile. With regard to the method, the invention is characterized in that an additional material component is introduced as a connecting means between the brush body and the bristle carrier. This results in the finished brush already explained above advantages.
Bevorzugt werden dabei der Bürstenkörper und der Borstenträger beabstandet zueinander gehalten und die zusätzliche Material- Komponente in den Zwischenraum zwischen Bürstenkörper und Borstenträger eingebracht. Beim Einbringen der zusätzlichen Material-Komponente, was üblicherweise im Spritzgießverfahren im erwärmten Zustand erfolgt, füllt diese den Zwischenraum aus und bildet dabei eine materialschlüssige Verbindung zwischen Bürstenkörper und Borstenträger. Preferably, the brush body and the bristle carrier are held spaced from each other and the additional material component introduced into the space between the brush body and bristle carrier. When introducing the additional material component, which usually takes place in the injection molding in the heated state, this fills the gap and thereby forms a material connection between the brush body and bristle carrier.
Dieses Herstellungsverfahren hat den großen Vorteil, dass sowohl der Bürstenkörper wie auch der Borstenträger zuvor auf separaten Spritzgießmaschinen hergestellt werden können und das Einbringen der zusätzlichen Material-Komponente dann auf einer dritten Spritzgießmaschine erfolgt. Jede dieser drei Spritzgießmaschinen kann dabei klein und einfach ausgebildet sein, so dass die Anschaffungskosten für eine entsprechende Fertigungseinrichtung gering sind und eine kostengünstige Pro- duktion möglich ist. Zudem können unterschiedlichste, vorgefertigte Bürstenkörper und Borstenträger an der dritten Spritzgießmaschine mit der zusätzlichen Material-Komponente miteinander verbunden werden, so dass mit geringem Aufwand ein vielfäl- tiges Bürstensortiment, beispielsweise mit Bürstenkörpern unterschiedlicher Farbe und Griff-Form und Borstenträgern mit unterschiedlich ausgebildetem Borstenfeld gefertigt werden kann . This manufacturing method has the great advantage that both the brush body and the bristle carrier can be previously produced on separate injection molding machines and then the introduction of the additional material component is carried out on a third injection molding machine. Each of these three injection molding machines can be made small and simple, so that the initial costs for a corresponding production device are low and cost-effective production is possible. In addition, a very wide variety of prefabricated brush bodies and bristle carriers can be connected to one another at the third injection molding machine with the additional material component, so that a great deal of effort can be made with little effort. tige brush assortment, for example, with brush bodies of different colors and handle shape and bristle carriers can be made with differently shaped bristle field.
Alternativ kann auch der Borstenträger mit der zusätzlichen Material-Komponente umspritzt werden, und anschließend wird der mit der zusätzlichen Material-Komponente versehene Borstenträger mit weiterem Material zur Bildung des Bürstenkörpers umspritzt . Alternatively, the bristle carrier can be overmolded with the additional material component, and then the bristle carrier provided with the additional material component is overmolded with further material to form the brush body.
Eine weitere Variante des erf indungsgemäßen Verfahrens sieht vor, dass die zusätzliche Material-Komponente auf den Bürstenkörper aufgebracht wird, dass der Borstenträger auf die zusätzliche Material-Komponente aufgebracht wird und dass dann der Bürstenkörper und der Borstisnträger jeweils mit der zusätz- liehen Material-Komponente verbimden werden. A further variant of the erf indungsgemäßen method provides that the additional material component is applied to the brush body, that the bristle carrier is applied to the additional material component and that then the brush body and the Borstisnträger each with the additional borrowed material component be verbimden.
Das Verbinden des Bürstenkörpers und des Borstenträgers mit der zusätzlichen Material-Komponente kann dabei insbesondere durch Anschmelzen erfolgen. The bonding of the brush body and the bristle carrier with the additional material component can be effected in particular by melting.
Nachstehend ist die Erfindung anhand der Zeichnungen näher erläutert . The invention is explained in more detail with reference to the drawings.
Es zeigt etwas schematisiert: It shows something schematized:
Fig. 1 bis Fig. 1 to
Fig. 6 jeweils einen Querschnitt einer erfindungsgemäßen  Fig. 6 each a cross section of an inventive
Bürste .  Brush.
Eine im ganzen mit 1 bezeichnete Bürste weist gemäß Figuren 1 bis 6 jeweils einen Bürstenkörper 2 sowie Borstenbündel 3, die an ihrem verbindungsseitigen Ende einen angeschmolzenen Haltebereich 6 haben und an einem Borstenträger 4 gehalten sind, auf. Sowohl der Bürstenkörper 2 wie auch der Borstenträger 4 sind jeweils ein Spritzgießteil aus starrem Material. A generally designated 1 brush has, according to Figures 1 to 6 each have a brush body 2 and bristle bundles 3, the at their connection-side end have a fused holding portion 6 and are held on a bristle carrier 4, on. Both the brush body 2 and the bristle carrier 4 are each an injection molded part of rigid material.
Zwischen dem Bürstenkörper 2 und dem Borstenträger 4 ist dabei jeweils eine Zwischenschicht 5 aus einer zusätzlichen, elastischen Material-Komponente vorgesehen. Dadurch ist der Borstenträger 4 nicht starr mit dem Bürstenkörper 2 verbunden, sondern praktisch "schwimmend" gelagert, so dass die Borstenbündel 3 bei der Benutzung der hier als Zahnbürste ausgebildeten Bürste 1 besser ausweichen und sich der Kontur der Zähne anpassen können, wodurch eine gründlichere und schonendere Reinigung möglich ist. Die befestigungsseitigen Enden der Borstenbündel 3 sind jeweils von dem Material des Borstenträgers 4 umschlossen, so dass der Borstenträger 4 eine die Zwischenschicht 5 und die Borstenbündel 3 auf Abstand haltende Trennschicht bildet. Die zusätzliche Material-Komponente der Zwischenschicht 5 kommt somit nicht mit dem Borstenmaterial oder dem angeschmolzenen Haltebereich 6 der Borstenbündel 3 in Berührung, so dass beim Einspritzen der zusätzlichen Material-Komponente der Zwischenschicht 5 beim Herstellen der Bürste 1 Überspritzungen im Borstenbereich vermieden sind. In each case an intermediate layer 5 made of an additional, elastic material component is provided between the brush body 2 and the bristle carrier 4. As a result, the bristle carrier 4 is not rigidly connected to the brush body 2, but stored practically "floating" so that the bristle bundles 3 evade better when using the trained here as a toothbrush brush 1 and can adapt to the contour of the teeth, creating a more thorough and Gentle cleaning is possible. The fastening-side ends of the bristle bundles 3 are each enclosed by the material of the bristle carrier 4, so that the bristle carrier 4 forms a separating layer which holds the intermediate layer 5 and the bristle bundles 3 at a distance. The additional material component of the intermediate layer 5 thus does not come into contact with the bristle material or the fused holding region 6 of the bristle bundles 3, so that overmolding in the bristle region is avoided when the additional material component of the intermediate layer 5 is injected during the manufacture of the brush 1.
Bei der Bürste 1 gemäß Figur 1 sind die Zwischenschicht 5 und der Borstenträger 4 in einer wannenartigen Vertiefung des Bürstenkörpers 2 angeordnet. Dadurch ist die elastische Material- Komponente der Zwischenschicht 5 lediglich als Umrandung auf der Borstenfeldseite sichtbar, während die Seitenflächen des Bürstenkörpers 2 durch dessen Material bestimmt sind. In the brush 1 according to FIG. 1, the intermediate layer 5 and the bristle carrier 4 are arranged in a trough-like depression of the brush body 2. As a result, the elastic material component of the intermediate layer 5 is visible only as a border on the bristle field side, while the side surfaces of the brush body 2 are determined by its material.
Bei der Bürste 1 gemäß Figur 2 erstreckt sich das elastische Material der Zwischenschicht 5 bis an den Rand des Bürstenkörpers 2 und des Borstenträgers 4, so dass das elastische Material der Zwischenschicht 5 seitlich sichtbar ist. Der Borstenträger 4 kann dabei stärker als bei der Bürste gemäß Figur 1 seitlich ausweichen und sich gegenüber dem Bürstenkörper 2 verschieben, so dass sich die Borstenbündel 3 noch stärker an die Zähne beziehungsweise die zu reinigende Oberfläche anpassen können. Bei der Bürste 1 gemäß Figur 3 steht das elastische Material der Zwischenschicht 5 seitlich über den Borstenträger 4 und am freien Ende des Bürstenkörpers 2 auch über diesen über. Die Zwischenschicht 5 bildet so zusätzlich ein Polster, mit dem die Bürste 1 gegen Beschädigungen geschützt werden kann. In the brush 1 according to Figure 2, the elastic extends Material of the intermediate layer 5 to the edge of the brush body 2 and the bristle carrier 4, so that the elastic material of the intermediate layer 5 is laterally visible. The bristle carrier 4 can deflect laterally stronger than in the brush of Figure 1 and move relative to the brush body 2, so that the bristle bundles 3 can even more adapted to the teeth or the surface to be cleaned. In the brush 1 according to Figure 3, the elastic material of the intermediate layer 5 is laterally beyond the bristle carrier 4 and at the free end of the brush body 2 via this. The intermediate layer 5 thus additionally forms a cushion with which the brush 1 can be protected against damage.
Bei der Bürste 1 gemäß Figur 4 sind an dem Borstenträger 4 in Richtung zum Bürstenkörper 2 vorstehende Auflageelemente 7 vorgesehen, mit denen der Borstenträger 4 an dem Bürstenkörper 2 anliegt. Dies ermöglicht eine exakte Positionierung des Bors- tenträgers 4 und des Bürstenkörpers 2 relativ zueinander beim Einsetzen in die Spritzform zum Spritzen der Zwischenschicht 5 und eine entsprechend genaue Beabstandung des Borstenträgers 4 und des Bürstenkörpers 2 zueinander. Durch die spitz zulaufenden Auflageelemente 7 werden diese zusätzlich leicht in das Ma- terial des Bürstenkörpers 2 eingedrückt, wodurch der Halt weiter verbessert ist. In the case of the brush 1 according to FIG. 4, support elements 7 projecting in the direction of the brush body 2 are provided on the bristle carrier 4 with which the bristle carrier 4 bears against the brush body 2. This enables exact positioning of the bristle carrier 4 and of the brush body 2 relative to each other during insertion into the injection mold for spraying the intermediate layer 5 and a correspondingly accurate spacing of the bristle carrier 4 and the brush body 2 from each other. Due to the tapered support elements 7, these are additionally pressed easily into the material of the brush body 2, as a result of which the hold is further improved.
Bei der Bürste 1 gemäß Figur 5 weist der Bürstenkörper 2 mehrere Auflageelemente 7 auf, die mit ihrem freien Ende jeweils in eine Aufnahme 8 des Borstenträgers 4 eingreifen und somit Bürstenkörper 2 und Borstenträger 4 ebenfalls in einem definierten Abstand zueinander gelagert sind. Zudem ist durch das Eingreifen der Auflageelemente 7 in die Aufnahmen 8 eine bes- sere Kraftübertragung zwischen Bürstenkörper 2 und Borstenträger 4 gegeben, was insbesondere bei oszillierend rotierenden Bürstenköpfen von elektrischen Zahnbürsten wichtig ist. In the brush 1 according to Figure 5, the brush body 2 a plurality of support elements 7 which engage with their free end respectively in a receptacle 8 of the bristle carrier 4 and thus brush body 2 and bristle carrier 4 are also stored at a defined distance from each other. In addition, by engaging the support elements 7 in the receptacles 8 a bes- Sere power transmission between the brush body 2 and bristle carrier 4 given, which is particularly important for oscillating brush heads rotating electric toothbrushes.
Mit der zusätzlichen Materialkomponente ist bei der Bürste 1 gemäß Figur 5 nicht nur die Zwischenschicht 5 gespritzt, sondern auch zusätzliche Funktionselemente in Form einer in das Borstenfeld vorstehenden Massagenoppe 9a und eines Zungenschabers 9b an der Rückseite des Bürstenkörpers 2. Die zusätzlichen Funktionselemente sind mit der Zwischenschicht 5 verbunden, so dass diese in einem gemeinsamen Spritzvorgang in einer entsprechend ausgebildeten Spritzform erzeugt werden können. With the additional material component not only the intermediate layer 5 is sprayed in the brush 1 according to Figure 5, but also additional functional elements in the form of a in the bristle field above Massagenoppe 9a and a tongue scraper 9b on the back of the brush body 2. The additional functional elements are with the intermediate layer 5, so that they can be produced in a common injection molding in a suitably trained mold.
Die Bürste 1 gemäß Figur 6 weist ebenfalls zusätzliche Funktionselemente in Form eines Zungenschabers 9b und eines Schleimhautschutzes 9c auf. Letzterer soll Verletzungen im Mundraum beim Putzen verhindern. The brush 1 according to FIG. 6 also has additional functional elements in the form of a tongue scraper 9b and a mucous membrane protection 9c. The latter is intended to prevent injuries in the mouth during cleaning.
Bei der Bürste 1 gemäß Figur 6 sind an dem Bürstenkörper 2 Auflageelemente 7 vorgesehen, auf denen der Borstenträger 4 aufliegt und so, ähnlich der Bürste 1 aus Figur 4, bei der Aufla- geelemente 7 an dem Borstenträger 4 vorgesehen sind, ein definierter Abstand zwischen Bürstenkörper 2 und Borstenträger 4 zum Spritzen der Zwischenschicht 5 gebildet ist.  In the brush 1 according to FIG. 6, support elements 7 are provided on the brush body 2, on which the bristle carrier 4 rests and thus, similar to the brush 1 of FIG. 4, are provided with a defined distance between the support elements 7 on the bristle carrier 4 Brush body 2 and bristle carrier 4 for spraying the intermediate layer 5 is formed.
Die Bürsten 1 können jeweils hergestellt werden, indem der die Borstenbündel 3 tragende Borstenträger 4 in eine Spritzgießmaschine eingesetzt wird und dort zunächst die zusätzliche Materialkomponente für die Zwischenschicht 5 und anschließend weiteres Material zur Bildung des Bürstenkörpers 2 angespritzt wird . The brushes 1 can each be produced by the bristle carrier 4 carrying the bristle bundles 3 is inserted into an injection molding machine and there first, the additional material component for the intermediate layer 5 and then further material for the formation of the brush body 2 is molded.
Es ist jedoch auch möglich, zunächst den Borstenträger 4 und den Bürstenkörper 2 separat zu spritzen, diese dann in einer Spritzgießform beabstandet zueinander zu halten und die zusätzliche Materialkomponente für die Zwischenschicht 5 dazwischen einzuspritzen. Dieses Herstellungsverfahren hat den Vorteil, dass jeweils einfache Spritzgießmaschinen für die einzelnen Komponenten in unterschiedlichen Ausführungen verwendet werden können, was deren Produktion kostengünstig ermöglicht, die dann beliebig miteinander kombiniert werden können. Beispielsweise können Bürstenkörper unterschiedlicher Form und Farbe mit Borstenträgern kombiniert werden, die ihrerseits Borstenbündel in unterschiedlicher Anordnung und/oder Profilierung aufweisen. Somit ist es mit geringem Aufwand möglich, Sortimente unterschiedlicher Bürsten zusammenzustellen. However, it is also possible first to spray the bristle carrier 4 and the brush body 2 separately, then in a Keep injection mold spaced from each other and inject the additional material component for the intermediate layer 5 therebetween. This manufacturing method has the advantage that in each case simple injection molding machines for the individual components can be used in different versions, which enables their production cost-effective, which can then be combined with each other arbitrarily. For example, brush body of different shape and color can be combined with bristle carriers, which in turn have bristle bundles in a different arrangement and / or profiling. Thus, it is possible with little effort to assemble assortments of different brushes.
