Description

Die Erfindung betrifft eine Handbürste zum Reinigen von Prothesen, insbesondere Zahnprothesen, mit einem Borstenträger, der mit einem Handgriffteil verbunden ist.The invention relates to a hand brush for cleaning prostheses, in particular dental prostheses, with a bristle holder which is connected to a handle part.

Die bisher bekannten Handbürsten zum Reinigen von Prothesen sind überwiegend Stielbürsten. Dies gilt auch für Bürsten zum Reinigen von Zahnprothesen, die nach Art von Zahnbürsten ausgebildet sind und eine relativ kleine Borstenfläche aufweisen. Von Zahnprothesenträgern, die überwiegend ältere Menschen sind, wird eine schwierige Handhabung bekannter Zahnprothesenbürsten bemängelt. Von ärztlicher Seite wird gefordert, daß Bürsten zum Reinigen von Prothesen hygienisch gestaltet sind.The hand brushes known to date for cleaning prostheses are predominantly stick brushes. This also applies to brushes for cleaning dental prostheses, which are designed in the manner of toothbrushes and have a relatively small bristle area. Denture wearers, who are predominantly older people, complain about the difficult handling of known denture brushes. From the medical side it is required that brushes for cleaning prostheses are designed hygienically.

Der Erfindung liegt die Aufgabe zugrunde, eine Handbürste zum Reinigen von Prothesen, insbesondere Zahnprothesen, zu schaffen, die sich gut und sicher handhaben läßt und hygienischen Anforderungen voll entspricht.The invention has for its object to provide a hand brush for cleaning prostheses, in particular dental prostheses, which can be handled well and safely and fully meets hygienic requirements.

Die gestellte Aufgabe wird mit einer Handbürste der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß die gesamte Handbürste recyclebar aus sterilisierbaren und lebensmittelgeeigneten Kunststoffmaterialien gefertigt ist, wobei die elastischen Borsten einstückig mit einem großflächigen Borstenträger gefertigt sind und der Borstenträger mittels einer Rastverbindung unlösbar mit dem Handgriffteil verbunden ist.The object is achieved with a hand brush of the type mentioned in the present invention in that the entire hand brush is made from recyclable, sterilizable and food-compatible plastic materials, the elastic bristles being made in one piece with a large-area bristle carrier and the bristle carrier being non-detachably connected to the handle part by means of a snap connection is.

Die erfindungsgemäß ausgebildete Handbürste ist in allen ihren Teilen aus gleichartigen Kunststoffmaterialien gefertigt, so daß sich alte Bürsten als Ganzes einer Wiederverwertungsanlage zuführen lassen. Neben diesem umweltschützenden Aspekt hat die Handbürste gemäß der Erfindung einen wichtigen hygienischen Vorteil. Durch die einstückige Ausbildung der Borsten mit dem Borstenträger sind keine Bohrungen im Borstenträger zur Befestigung von Borsten notwendig, in welche sich Schmutz und Bakterien festsetzen könnten. Borsten und Borstenkörper lassen sich aus einem lebensmittelgeeigneten Weichplastikmaterial mit beliebiger Weichheit auskochbar und sterilisierbar als einstückiges Spritzgußteil herstellen. Für den Handgriffteil und die Rastverbindung werden ähnliche Kunststoffmaterialien verwendet, so daß die Bürste als Ganzes auskochbar ist. Die große Borstenfläche in Verbindung mit einem gut erfaßbaren, vorteilhafterweise konzentrisch und/oder symmetrisch zu einer Symmetrieachse oder Symmetrieebene des Borstenteiles ausgebildeten Handgriffteil erlaubt auch älteren Menschen eine leichte und sichere Handhabung der Handbürste. Der Borstenträger kann entweder mittels eines Rastkoppelungsteiles oder unmittelbar mit dem Handgriffteil unlösbar rastend verbunden sein.The hand brush designed according to the invention is made in all its parts from similar plastic materials, so that old brushes as a whole can be fed to a recycling plant. In addition to this environmental protection aspect, the hand brush according to the invention has an important hygienic advantage. Due to the one-piece design of the bristles with the bristle carrier, no holes in the bristle carrier are necessary for fastening bristles in which dirt and bacteria could become lodged. Bristles and bristle bodies can be boiled out of a soft plastic material suitable for foodstuffs with any degree of softness and can be sterilized as a one-piece injection molded part. Similar plastic materials are used for the handle part and the locking connection, so that the brush can be boiled out as a whole. The large bristle surface in conjunction with a handle part that is easy to grasp, advantageously concentric and / or symmetrical to an axis of symmetry or plane of symmetry of the bristle part also allows older people easy and safe handling of the hand brush. The bristle carrier can be connected in a non-detachable manner either by means of a locking coupling part or directly to the handle part.

Vorteilhafterweise können die Borsten dünn und spitz auslaufen und an einem plattenartigen Borstenkörper angeformt sein. Zweckmäßig kann der plattenförmige Borstenkörper auf seiner den Borsten abgewandten Rückseite einen Randsteg aufweisen, der zu einer Ringnut für die formschlüssige Aufnahme eines tellerförmigen Endes des Rastkoppelungsteiles oder des Handgriffteiles hinterschnitten ist. Für eine leichte und sichere, unlösbare Verbindung des gesondert gefertigten Handgriffteiles mit dem Borstenträger mittels eines Rastkoppelungsteiles hat sich eine Gliederung des tellerförmigen Endes des Rastkoppelungsteiles in zwei entlang einer Durchmesserlinie gegeneinander verschwenkbare Hälften als vorteilhaft erwiesen, die jeweils eine senkrecht von der Tellerhälfte abstehende Kupplungssteghälfte aufweisen, die bei miteinander fluchtenden Tellerhälften gegeneinanderliegen und die auf ihren Außenseiten Rastvorsprünge oder Rastausnehmungen aufweisen, die bei durch eine passende Öffnung des Handgriffteiles eingeschobenem Kupplungssteg mit auf der Innenseite des Handgriffteiles ausgebildeten Rastausnehmungen oder -vorsprüngen formschlüssig zusammenwirken. Durch ein Verschwenken der beiden Tellerhälften läßt sich das tellerförmige Ende des Rastkoppelungsteiles so gegen die Rückseite des Borstenträgers ansetzen, daß die Tellerhälften in die Ringnut des Randsteges des Borstenkörpers formschlüssig eingeschoben werden können. Anschließend wird dann der Kupplungssteg des Rastkoppelungsteiles in die passende Öffnung des Griffteiles eingeschoben, wo er unlösbar einrastet und seine beiden Häften daran gehindert sind, sich aus ihrer gegenseitigen Anlage wieder zu lösen. Bei einem Verzicht auf ein Rastkoppelungsteil zwischen dem Borstenträger und dem Handgriffteil kann letzteres in zwei gegeneinander verschwenkbare Hälften unterteilt sein, die auf ihrerAdvantageously, the bristles can run out thin and pointed and can be molded onto a plate-like bristle body. The plate-shaped bristle body can expediently have an edge web on its rear side facing away from the bristles, which is undercut to form an annular groove for the positive reception of a plate-shaped end of the latching coupling part or of the handle part. For an easy and secure, non-detachable connection of the separately manufactured handle part to the bristle carrier by means of a snap coupling part, it has proven advantageous to divide the plate-shaped end of the snap coupling part into two halves that can be swiveled along a diameter line, each of which has a coupling web half protruding perpendicularly from the plate half, which lie against each other when the plate halves are aligned with one another and which have latching projections or latching recesses on their outer sides which, when the coupling web is pushed in by a suitable opening of the handle part, cooperate in a form-fitting manner with latching recesses or projections formed on the inside of the handle part. By pivoting the two plate halves, the plate-shaped end of the locking coupling part can be placed against the back of the bristle carrier in such a way that the plate halves can be positively inserted into the annular groove of the edge web of the bristle body. Then the coupling web of the locking coupling part is then inserted into the suitable opening of the handle part, where it snaps in place and its two forces are prevented from detaching from each other again. If there is no latching coupling part between the bristle carrier and the handle part, the latter can be divided into two halves which can be pivoted relative to one another and which rest on their

Innenseite jeweils mit Rastnoppen und passenden Ausnehmungen zum gegenseitigen Verbinden versehen sind. Auch bei dieser Ausführungsform läßt sich durch ein Verschwenken der beiden Griffteilhälften ein daran angeformter Tellerrand in eine entsprechende Rastnut am Borstenträger bequem einführen, bevor die Hälften anschließend unlösbar rastend miteinander verbunden werden. Eine sichere Abdichtung der zwischen Borstenträger und Griffteil bestehenden Anlageflächen kann leicht dadurch erreicht werden, daß der Öffnungsrand des Handgriffteiles und/oder der Randsteg des Borstenträgers nach außen einen angeformten Dichtwulst oder eine angeformte Dichtlippe aufweisen.Inside each have locking knobs and matching recesses for mutual connection. In this embodiment, too, by pivoting the two halves of the handle part, a plate rim formed thereon can be conveniently inserted into a corresponding locking groove on the bristle carrier before the halves are then non-detachably connected to one another. A reliable sealing of the contact surfaces existing between the bristle holder and the handle part can easily be achieved in that the opening edge of the handle part and / or the edge web of the bristle holder have a molded sealing bead or a molded sealing lip on the outside.

Nachfolgend wird ein Ausführungsbeispiel einer erfindungsgemäß ausgebildeten Handbürste für das Reinigen von Zahnprothesen anhand der beiliegenden Zeichnung näher erläutert.An exemplary embodiment of a hand brush designed according to the invention for cleaning dental prostheses is explained in more detail with reference to the accompanying drawing.

Die Handbürste 10 besteht aus einem Handgriffteil 11 und einem Borstenträger 12, die als gesonderte Formteile aus Kunststoffmaterialien gefertigt sind, die metallfrei und damit lebensmittelgeeignet, auskochbar und sterilisierbar sind. Der Handgriffteil 11 weist einen länglichen balligen Rücken 11.1 auf, an welchen sich in Richtung auf den Borstenträger 12 allseitig eine Griffmulde 11.2 anschließt. Der Handgriffteil 11 ist symmetrisch zu einer durch die Schnittlinie II - II gekennzeichneten Symmetrieebene des Borstenträgers 12 ausgebildet, der als Platte ausgebildet ist, die beispielsweise eine kreisrunde Form hat. Wie aus der Schnittdarstellung der Fig. 2 ersichtlich ist, sind auf der einen Seite des plattenförmigen Borstenträgers 12 spitz auslaufende Borsten 13 direkt angeformt. Borstenträger 12 und Borsten 13 sind also einstückig aus einem Weichplastikmaterial gefertigt. Auf seiner Rückseite ist der plattenförmige Borstenträger 12 mit einem Randsteg 12.1 versehen, dessen Endbereich 12.2 nach einwärts abgewinkelt ist, so daß der Randsteg 12.1/12.2 eine Ringnut 14 begrenzt. Der einwärts abgewinkelte Randbereich 12.2 des Randsteges 12.1 bildet eine Anlagefläche für den Handgriffteil 11 und ist in diesem Bereich mit einem elastischen Dichtwulst 12.3 ausgebildet. Dieser Dichtwulst, der ein Eindringen von Flüssigkeit in das Innere der Handbürste 10 vermeidet, kann auch am Handgriffteil 11 ausgebildet sein.The hand brush 10 consists of a handle part 11 and a bristle carrier 12, which are made as separate molded parts from plastic materials that are metal-free and therefore suitable for food, boilable and sterilizable. The handle part 11 has an elongated spherical back 11.1, to which a recessed grip 11.2 is connected on all sides in the direction of the bristle carrier 12. The handle part 11 is formed symmetrically with respect to a plane of symmetry of the bristle carrier 12 which is characterized by the section line II-II and which is designed as a plate which, for example, has a circular shape. As can be seen from the sectional view in FIG. 2, bristles 13 which taper to a point are formed directly on one side of the plate-shaped bristle carrier 12. Bristle carrier 12 and bristles 13 are thus made in one piece from a soft plastic material. On its rear side, the plate-shaped bristle carrier 12 is provided with an edge web 12.1, the end region 12.2 of which is angled inwards, so that the edge web 12.1 / 12.2 delimits an annular groove 14. The inwardly angled edge area 12.2 of the edge web 12.1 forms a contact surface for the handle part 11 and is formed in this area with an elastic sealing bead 12.3. This sealing bead, the Prevents liquid from penetrating into the interior of the hand brush 10 can also be formed on the handle part 11.

Eine unlösbare Verbindung des Handgriffteiles 11 mit dem Borstenträger 12 ist durch ein Rastkoppelungsteil 15 geschaffen, das in Fig. 3 einzeln und in Seitenansicht dargestellt ist. Das Rastkoppelungsteil 15 besteht aus einem Teller 16, dessen Abmessungen an den plattenförmigen Borstenträger 12 so angepaßt sind, daß der Teller gemäß der Schnittdarstellung der Fig. 2 mindestens mit dem größten Teil seines Außenrandes in die am Borstenträger 12 ausgebildete Ringnut 14 paßt. Durch eine entlang einer Durchmesserlinie verlaufende Kerbe 17 ist der Teller 16 in zwei miteinander gelenkig verbundene Hälften 16/1 und 16/2 geteilt. Diese Teilung ist auch an einem nach der einen Seite des Tellers 16 abstehenden Kupplungssteg 18 entlang einer durch die Kerbe 17 verlaufenden Ebene gemacht. Die beiden Hälften des Kupplungssteges 18 sind mit 18/1 und 18/2 bezeichnet. An einander entgegengesetzten Außenseiten sind beide Kupplungssteghälften 18/1 und 18/2 mit einem vorspringenden Raststeg 19 versehen. Befinden sich die beiden Tellerhälften 16/1 und 16/2 fluchtend in ihrer gemeinsamen Tellerebene, liegen die beiden Kupplungssteghälften 18/1 und 18/2 gegeneinander. Aus dieser Wirkstellung lassen sich die beiden Tellerhälften 16/1 und 16/2 mit ihren Kupplungssteghälften 18/1 und 18/2 in eine in Fig. 3 mit strichpunktierten Linien eingetragene Winkellage verschwenken. In dieser Winkellage lassen sich die beiden Tellerhälften 16/1 und 16/2 mit ihrem Außenrand in die Ringnut 14 des Borstenträgers 12 einschieben und anschließend in ihre Fluchtstellung bringen, in welcher die beiden Kupplungssteghälften 18/1 und 18/2 gegeneinanderliegen. In dieser Stellung läßt sich der Kupplungssteg 18 in eine passende, zur Unterseite des Handgriffteiles 11 hin offene Ausnehmung 20 einschieben. Seitenwandungen der Ausnehmung sind mit Rastausnehmungen 21 versehen, in welche die Rastvorsprünge 19 der Kupplungssteghälften 18/1 und 18/2 unter Schaffung einer unlösbaren Verbindung von Handgriffteil 11 und Borstenträger 12 einrasten können. Das für die Herstellung des Rastkoppelungsteiles 15 und des Handgriffteiles 11 verwendete Kunststoffmaterial weist eine ausreichende Elastizität auf, welche eine ausreichende elastische Verformung dieser Teile bei der Bildung der Rastverbindung erlaubt.A non-detachable connection of the handle part 11 to the bristle carrier 12 is created by a snap coupling part 15, which is shown individually and in a side view in FIG. 3. The locking coupling part 15 consists of a plate 16, the dimensions of which are adapted to the plate-shaped bristle carrier 12 so that the plate according to the sectional view in FIG. 2 fits at least with the major part of its outer edge into the annular groove 14 formed on the bristle carrier 12. The plate 16 is divided into two hinged halves 16/1 and 16/2 by a notch 17 running along a diameter line. This division is also made on a coupling web 18 projecting to one side of the plate 16 along a plane running through the notch 17. The two halves of the coupling web 18 are designated 18/1 and 18/2. On opposite outer sides, both coupling web halves 18/1 and 18/2 are provided with a projecting locking web 19. If the two plate halves 16/1 and 16/2 are aligned in their common plate plane, the two coupling web halves 18/1 and 18/2 lie against each other. From this operative position, the two plate halves 16/1 and 16/2 with their coupling web halves 18/1 and 18/2 can be pivoted into an angular position shown in broken lines in FIG. 3. In this angular position, the two plate halves 16/1 and 16/2 can be pushed with their outer edge into the annular groove 14 of the bristle carrier 12 and then brought into their alignment position, in which the two coupling web halves 18/1 and 18/2 lie against each other. In this position, the coupling web 18 can be inserted into a suitable recess 20 which is open towards the underside of the handle part 11. Side walls of the recess are provided with latching recesses 21, into which the latching projections 19 of the coupling web halves 18/1 and 18/2 can snap, creating a permanent connection between the handle part 11 and the bristle carrier 12. The plastic material used for the production of the locking coupling part 15 and the handle part 11 has sufficient elasticity, which allows a sufficient elastic deformation of these parts when the locking connection is formed.

In Fig. 4 ist eine Handbürste mit einem aus zwei Hälften 30/1 und 30/2 gebildeten Handgriffteil 30 dargestellt. Wie aus Fig. 5 ersichtlich ist, weisen die beiden Hälften 30/1 und 30/2 jeweils einen tellerförmigen Rand 33 auf, der in ähnlicher Weise wie der entsprechende Rand 16 des Rastkoppelungsteiles 15 in Fig. 3 in eine entsprechende, hier nicht näher dargestellte Ringnut des Borstenkörpers 34 eingeführt werden kann. Dazu werden die beiden Griffhälften 30/1 und 30/2 in ähnlicher Weise wie die Hälften des Rastkoppelungsteiles 15 verschwenkt, in die Ringnut des Borstenkörpers 34 eingeführt und anschließend zusammengedrückt. Dabei rasten an der Innenseite der Hälften 30/1 und 30/2 angeformte Rastnoppen 31 in ebenfalls auf der Innenseite der Hälften 30/1 und 30/2 angeordnete Ausnehmungen 32 formschlüssig ein, wodurch sich eine unlösbare Verbindung des Borstenträgers 34 mit dem Griffteil 30 ergibt. Sämtliche Hälften 30/1 und 30/2 sind dabei vollkommen identisch ausgeführt, d. h. sie weisen auf der einen Seite ihrer Längssymmetrieachse 35 stets Noppen 31 und auf der anderen Seite stets Ausnehmungen 32 auf. Auf diese Weise passen immer zwei Hälften 30/1 und 30/2 zusammen. Das Herstellen unterschiedlich ausgeformter linker und rechter Hälften entfällt.FIG. 4 shows a hand brush with a handle part 30 formed from two halves 30/1 and 30/2. As can be seen from FIG. 5, the two halves 30/1 and 30/2 each have a plate-shaped edge 33 which, in a manner similar to the corresponding edge 16 of the latching coupling part 15 in FIG Annular groove of the bristle body 34 can be inserted. For this purpose, the two handle halves 30/1 and 30/2 are pivoted in a manner similar to that of the halves of the locking coupling part 15, inserted into the annular groove of the bristle body 34 and then pressed together. In this case, snap-in knobs 31 integrally formed on the inside of the halves 30/1 and 30/2 snap into recesses 32 which are likewise arranged on the inside of the halves 30/1 and 30/2, which results in a permanent connection between the bristle carrier 34 and the handle part 30 . All halves 30/1 and 30/2 are completely identical, ie they always have knobs 31 on one side of their longitudinal axis of symmetry 35 and recesses 32 on the other side. On this way, two halves 30/1 and 30/2 always fit together. There is no need to produce differently shaped left and right halves.
