Abstract

The method involves manufacturing a carrier plate (10) with holes (14) for fiber bundles and a soft elastic element (12). The elastic element is manufactured by extruding an elastic material in a spraying mold by the holes. The bundles are inserted into the holes. Fastening ends of the bundles withdrawing from the holes are fastened to the plate by edge melting. The elastic element and the bundles are inserted into the plate and another spraying mold, respectively, where a part of a brush body is molded at the plate. An independent claim is also included for a brush comprising a carrier plate.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Bürsten, insbesondere Zahnbürsten.The invention relates to a method for producing brushes, in particular toothbrushes.

Traditionell erfolgt die Befestigung von Borstenbündeln oder Faserbündeln an Bürstenkörpern mittels Schlingen oder metallischen Ankerplättchen. Bei Verfahren, die ohne Schlingen oder Ankerplättchen auskommen, werden Faserbündel an Trägerplättchen befestigt, indem ihre Befestigungsenden in Löcher des Trägerplättchens eingeführt und auf dessen Rückseite verschmolzen werden. Mit diesem "ankerlosen" Verfahren können Faserbündel in nahezu beliebiger Querschnittsform verarbeitet werden. Es besteht vielfach der Wunsch, außer den üblichen Borsten und Faserbündeln auch Reinigungselemente in das Borstenfeld zu integrieren (z.B. Reinigungselemente aus weichelastischem Material, Stifte, Stäbchen, Plättchen usw.). Zu diesem Zweck werden die Trägerplättchen mit zusätzlichen Löchern oder Aussparungen versehen, in die das weichelastische Material mit einer Spritzgießtechnik eingebracht wird. Je höher die Ansprüche an die Gestaltung und Funktionalität der Bürsten sind, desto komplexer und aufwendiger wird ihre Herstellung.Traditionally, the attachment of bristle bundles or fiber bundles to brush bodies by means of slings or metallic anchor plates. In processes that do not require loops or anchor plates, fiber bundles are attached to carrier platelets by inserting their attachment ends into holes in the carrier plate and fusing them to the back thereof. With this "anchorless" method fiber bundles can be processed in almost any cross-sectional shape. There is often a desire to incorporate cleaning elements into the bristle field (e.g., soft elastic cleaning elements, pins, rods, wafers, etc.) in addition to conventional bristles and fiber bundles. For this purpose, the carrier plates are provided with additional holes or recesses, in which the soft elastic material is introduced by an injection molding technique. The higher the demands on the design and functionality of the brushes, the more complex and expensive their production becomes.

Mit dem erfindungsgemäßen Verfahren, das in den beigefügten Patentansprüchen angegeben ist, werden die Vorteile der spritztechnischen Herstellung mit denen der ankerlosen bzw. schlingenlosen Befestigungstechnik vereint, um auch komplexe Bürstenausführungen rationell herstellen zu können.With the method according to the invention, which is specified in the appended patent claims, the advantages of the injection molding production are combined with those of the anchorless or loopless fastening technique, in order to be able to produce even complex brush designs efficiently.

Further features and advantages of the invention will become apparent from the following description of several embodiments with reference to the drawings. In the drawings show:
  • Fig. 1 a, 1b and 1 c successive steps of the manufacturing process in plan view in a first embodiment of a toothbrush;

Drei Herstellungsschritte des erfindungsgemäßen Verfahrens zur Herstellung einer Bürste, hier einer Zahnbürste, sind in Figur 1a bis 1 c dargestellt. Figur 1 a ist die Draufsicht eines Trägerplättchens 10 aus einem relativ harten Kunststoff, das eine allgemein ovale Form entsprechend dem Kopf einer Zahnbürste aufweist. Es wird in einem Zweikomponenten-Spritzgießwerkzeug einteilig mit weichelastischen stiftförmigen Elementen 12 aus einem Elastomermaterial und mit einer Gruppe von Bündellöchern 14 geformt, deren Anordnung einem gewünschten Borstenbild entspricht. Fig. 2a ist eine entsprechende Perspektivansicht.Three production steps of the method according to the invention for producing a brush, here a toothbrush, are in FIGS. 1a to 1c shown. FIG. 1 a is the top view of a carrier plate 10 made of a relatively hard plastic having a generally oval shape corresponding to the head of a toothbrush. It is integrally formed in a two-component injection molding tool with soft-elastic pin-shaped elements 12 made of an elastomeric material and with a group of bundle holes 14 whose arrangement corresponds to a desired bristle image. Fig. 2a is a corresponding perspective view.

In einem zweiten Herstellungsschritt, der in den Fig. 1 b und 2b veranschaulicht ist, wird das Trägerplättchen 10 mit den angeformten weichelastischen Elementen 12 in ein Ankerlos-Beborstungswerkzeug eingebracht. Dort werden Faserbündel 16 in die Bündellöcher 14 eingeführt und an dem Trägerplättchen 10 befestigt, indem die durchgeschobenen Enden der Faserbündel 16 auf der Rückseite des Trägerplättchens durch Einwirkung von Hitze verschmolzen werden.In a second manufacturing step, in the Fig. 1 b and 2b is illustrated, the carrier plate 10 is introduced with the molded soft elastic elements 12 in an anchorless bristle tool. There fiber bundles 16 are inserted into the bundle holes 14 and secured to the carrier plate 10 by the pushed ends of the fiber bundles 16 are melted on the back of the carrier plate by the action of heat.

In einem dritten Herstellungsschritt, der in den Fig. 1c und 2c veranschaulicht ist, wird das Trägerplättchen 10 mit den weichelastischen Elementen 12 und den befestigten Faserbündeln 16 in eine Kavität eines Spritzgießwerkzeugs eingebracht, in dem ein Bürstenkörper 18 oder ein Teil davon an das Trägerplättchen 10 angespritzt wird. Der Bürstenkörper 18 kann das Trägerplättchen 10 an dessen Außenrand umgreifen, so dass dieses mit der Kunststoffmasse des Bürstenkörpers teilweise umspritzt wird. Dieser dritte Herstellungsschritt kann in Mehrkomponenten-Spritzgießtechnik ausgeführt werden, so dass z.B. Bürstengriffe oder Bürstenstiele mit eingelagerten Dekorelementen, Schriftzügen oder Funktionsteilen versehen werden können.In a third manufacturing step in the Fig. 1c and 2c is illustrated, the carrier plate 10 is introduced with the soft elastic elements 12 and the attached fiber bundles 16 in a cavity of an injection mold in which a brush body 18 or a part thereof is molded onto the carrier plate 10. The brush body 18 may surround the carrier plate 10 at its outer edge, so that it is partially encapsulated with the plastic mass of the brush body. This third manufacturing step can be carried out in multi-component injection molding be so that, for example, brush handles or brush handles can be provided with embedded decorative elements, lettering or functional parts.

Bei der in den Figuren 1 und 2 gezeigten Ausführungsform einer Zahnbürste sind die stiftförmigen weichelastischen Elemente 12 in zwei Gruppen zu vier Elementen an den äußeren Längsrändern des Trägerplättchens 10 angeordnet.In the in the Figures 1 and 2 shown embodiment of a toothbrush, the pin-shaped soft elastic elements 12 are arranged in two groups to four elements at the outer longitudinal edges of the carrier plate 10.

Bei der in den Figuren 3 und 4 dargestellten Ausführungsform einer Zahnbürste wird an dem Trägerplättchen 20 anstelle der stiftförmigen Elemente ein einzelnes allgemein kreuzförmiges weichelastisches Element 22 aus Elastomermaterial geformt, das von in Bündellöcher 24 eingesetzten Faserbündeln 26 umgeben ist. Ansonsten sind die Herstellungsschritte die gleichen wie in den Figuren 1 und 2 und werden daher nicht erneut beschrieben.
In den Fig. 5 bis 9 ist das Trägerplättchen 110 mit einem hochgezogenen Außenrand 110a versehen und hat wie bei der Ausführungsform nach Fig. 1 und Fig. 2 Durchgangslöcher für stiftförmige Elemente 112 aus Elastomermaterial sowie durchgehende Bündellöcher 114 für Faserbündel 116. Wie in Fig. 5 zu erkennen ist, bildet die Elastomermasse der Elemente 112 auf der Rückseite des Trägerplättchens 110 einen durchgehenden Materialstrang 112a, der die Befestigungsenden der Elemente 112 verbindet. Fig. 6 zeigt zusätzlich die in die Bündellöcher 114 eingesetzten Faserbündel 116, deren Befestigungsenden anschließend wie in Fig. 7 gezeigt verschmolzen werden und eine zusammenhängende Masseschicht 116a auf der Rückseite des Trägerplättchens 110 bilden. In das außenseitig von dem hochgezogenen Außenrand 110a des Trägerplättchens und bodenseitig durch die Masseschicht 116a sowie den Materialstrang 112a begrenzte Volumen wird dann gemäß Fig. 8 eine Masseschicht 120 eingebracht. Die Masseschicht 120 hat die Funktion einer Sperre gegen den Durchtritt plastifizierter Masse in dem darauffolgenden Herstellungsschritt, bei dem ein Bürstenstiel 118 an das Trägerplättchen 110 angespritzt oder dieses mit der Masse des Bürstenstiels umspritzt wird. Der bei diesem Herstellungsschritt erforderliche Spritzdruck kann - ohne die Sperre durch eine Masseschicht 120 - dazu führen, dass plastifizierte Masse in etwaige zwischen Faserbündeln 116 und Bündellöchern 114 verbliebene Freiräume eindringt und eventuell sogar auf der Außenseite des Trägerplättchens austritt. Durch Steuerung und Begrenzung des Spritzdrucks kann dieser unerwünschten Erscheinung vorgebeugt werden, jedoch unter Inkaufnahme kritischer Verfahrensparameter und unter Verzicht auf hohen Spritzdruck, der zur Erzielung optimaler Qualität des Erzeugnisses erwünscht ist. Die bei mäßigem Druck aufgespritzte Masseschicht 120, die aus einem unkritischen Material bestehen kann, verhindert beim Spritzen des Bürstenstiels zuverlässig den Durchtritt von gespritzter Masse in den Bündellöchern, so dass dieser Herstellungsschritt mit optimal eingestelltem Spritzdruck erfolgen kann.
Bei der in Fig. 9 gezeigten Ausführung ist die Masseschicht 120 von der Masse des Bürstenstiels 118 vollständig umspritzt und somit im Inneren des Bürstenkopfes verborgen. Bei anderen (nicht gezeigten) Ausführungen sind ein oder mehr Flächenbereich der Masseschicht 120 nicht vom Bürstenstiel abgedeckt und treten sichtbar und gegebenenfalls auch haptisch in Erscheinung, indem z.B. die Masseschicht 120 speziell gefärbt oder geformt ist oder aus einem speziellen Material wie Elastomer besteht.In the in the FIGS. 3 and 4 In the illustrated embodiment of a toothbrush, instead of the pin-shaped elements, a single generally cross-shaped soft-elastic element 22 made of elastomeric material is formed on the carrier plate 20, which is surrounded by fiber bundles 26 inserted into bundle holes 24. Otherwise, the manufacturing steps are the same as in the Figures 1 and 2 and therefore will not be described again.
In the Fig. 5 to 9 the carrier plate 110 is provided with a raised outer edge 110a and has as in the embodiment according to Fig. 1 and Fig. 2 Through holes for pin-shaped elements 112 made of elastomeric material and continuous bundle holes 114 for fiber bundles 116. As in Fig. 5 As can be seen, the elastomeric mass of the elements 112 on the rear side of the carrier plate 110 forms a continuous strand of material 112a, which connects the attachment ends of the elements 112. Fig. 6 additionally shows the fiber bundles 116 inserted into the bundle holes 114, the attachment ends of which then follow as in FIG Fig. 7 are merged and form a continuous mass layer 116a on the back side of the carrier plate 110. In the outside of the raised outer edge 110a of the carrier plate and the bottom side through the ground layer 116a and the material strand 112a limited volume is then according to Fig. 8 a mass layer 120 introduced. The ground layer 120 functions as a barrier against the passage of plasticized mass in the subsequent manufacturing step, in which a brush handle 118 is molded onto the carrier plate 110 or this is encapsulated with the mass of the brush handle. The injection pressure required in this production step can-without the barrier through a mass layer 120-cause plasticized mass to penetrate into any free spaces remaining between fiber bundles 116 and bundle holes 114 and possibly even escape on the outside of the carrier plate. By controlling and limiting the injection pressure of this undesirable phenomenon can be prevented, but at the expense of critical process parameters and waiving high injection pressure to achieve optimal quality of the product is desired. The sprayed at moderate pressure mass layer 120, which may consist of a non-critical material, reliably prevents the passage of sprayed mass in the bundle holes when spraying the brush handle so that this manufacturing step can be done with optimally adjusted injection pressure.
At the in Fig. 9 As shown embodiment, the ground layer 120 is completely encapsulated by the mass of the brush handle 118 and thus hidden inside the brush head. In other (not shown) embodiments, one or more surface areas of the ground layer 120 are not covered by the brush handle and appear visible and possibly also haptic in appearance, for example, the ground layer 120 is specially colored or shaped or consists of a special material such as elastomer.
