Description

Die Erfindung betrifft ein Verschlussteil eines Spannbügelverschlusses, insbesondere für Flaschen.The invention relates to a closure part of a clamp closure, in particular for Bottles.

Bügelflaschenverschlüsse herkömmlicher Bauart haben ein Verschlussteil aus einem Keramikmaterial, über das ein Gummiring als Dichtelement gestülpt ist. Solche Flaschen eignen sich aufgrund des wiederverschließbaren Verschlusses hervorragend als Mehrwegflaschen. Nachteilig ist jedoch die unzureichende Reinigungsmöglichkeit, insbesondere im Bereich zwischen keramischem Verschlussteil und Dichtring. Außerdem besteht das Problem, dass das an sich poröse keramische Material lasiert werden muss, um gasdicht zu sein. Dabei entstehen leicht Fehlstellen, durch die insbesondere Kohlensäure entweichen oder Sauerstoff eindringen kann.Bottle top closures of conventional design have a closure part made of one Ceramic material over which a rubber ring is placed as a sealing element. Such bottles are ideal as a because of the reclosable closure Returnable bottles. The disadvantage, however, is the insufficient possibility of cleaning, especially in the area between the ceramic closure part and the sealing ring. Moreover there is the problem that the porous ceramic material has to be glazed in order to to be gastight. This easily creates defects, due to the carbonic acid in particular can escape or oxygen can penetrate.

Aus der DE 295 04 848 U1 ist ein Bügelflaschenverschluss bekannt, der aus einem Verbundkörper aus zwei unterschiedlichen Kunststoffarten besteht. Dieser Verschlusskörper löst zwar die Probleme mangelnder Gasdichtigkeit und erleichtert auch die Reinigung im Falle von Mehrwegflaschen. Jedoch verursacht ein vollständig aus Kunststoff bestehendes Verschlussteil beim Recycling beschädigter Flaschen erhebliche Probleme. Darüber hinaus kann sowohl der optische als auch der sensitive Eindruck nicht überzeugen. Die Bedruckung von Kunststoff mit Emblemen ist weniger haltbar, so dass sie im Laufe der Zeit nach mehreren Flaschenumläufen verblasst. Dadurch entsteht beim Verbraucher der Eindruck, er habe kein frisches Getränk erworben.From DE 295 04 848 U1 a strap bottle closure is known which consists of a Composite body consists of two different types of plastic. This closure body solves the problems of insufficient gas tightness and also makes cleaning in the Case of reusable bottles. However, one made entirely of plastic Closure part when recycling damaged bottles considerable problems. Furthermore cannot convince both the optical and the sensitive impression. The printing Plastic with emblems is less durable, so it will wear off over time faded several bottle rounds. This gives consumers the impression that they are didn't buy a fresh drink.

Es ist Aufgabe der vorliegenden Erfindung, ein Verschlussteil eines Spannbügelverschlusses zu schaffen, das die aus dem Stand der Technik bekannten Nachteile nicht aufweist. Insbesondere soll das Verschlussteil eine ausreichende Gasdichtigkeit gewährleisten, ohne die Nachteile der vollständig aus Kunststoff bestehenden Verschlussteile aufzuweisen.It is an object of the present invention to provide a closure part of a clamp lock to create that does not have the disadvantages known from the prior art. In particular, the closure part should ensure sufficient gas tightness without to have the disadvantages of the closure parts made entirely of plastic.

Diese Aufgabe wird erfindungsgemäß durch ein Verschlussteil eines Spannbügelverschlusses, insbesondere für Flaschen, gelöst, das aus einem Grundkörper zur Aufnahme des Spannbügels und einem zumindest teilweise in die Flaschenmündung eintauchenden Dichtungsabschnitt besteht, wobei der Dichtungsabschnitt aus einem die Anlagefläche an der Flaschenmündung bildenden, elastischen Bereich und einem in geschlossenem Zustand nicht mit der Flaschenmündung in Berührung kommenden, nicht-elastischen Bereich besteht, wobei der elastische Bereich ringförmig auf dem nicht-elastichen Bereich angeordnet ist und der nicht-elastische Bereich im Ringinnern über den elastischen Bereich hinausragt. Der Spannbügelverschluss ist dadurch gekennzeichnet, dass der Grundkörper und der Dichtungsabschnitt durch eine Klemmverbindung miteinander verbunden sind und der Dichtungsabschnitt im Zweikomponenten-Spritzverfahren hergestellt ist.This object is achieved by a closure part Clamping bracket closure, especially for bottles, released from a base body for receiving the clamp and at least partially in the bottle mouth immersed sealing section, wherein the sealing section consists of a Contact surface the bottle mouth forming elastic area and in the closed state there is no non-elastic region coming into contact with the bottle mouth, the elastic region being arranged in a ring on the non-elastic region and the non-elastic area inside the ring protrudes beyond the elastic area. The Clamp clamp is characterized in that the base body and the Sealing section are connected by a clamp connection and the Sealing section is produced in a two-component injection molding process.

Das erfindungsgemäße Verschlussteil besteht aus einem Grundkörper, der zur Aufnahme des Spannbügels geeignet ist. Dies kann durch eine durchgehende Bohrung oder einander gegenüberliegende Sacklöcher erreicht werden, durch die der Bügel entweder hindurchgeführt oder in die der Bügel eingehakt wird. Der Grundkörper kann aus beliebigem, geeignetem Material bestehen, wobei sich insbesondere ein keramisches Material, wie z.B. Porzellan, ein Porzellanersatzstoff oder auch Glas eignet. Diese Materialien haben den Vorteil, dass sie gut bedruckbar sind und dem Verbraucher den Eindruck eines herkömmlichen Bügelverschlusses vermitteln.The closure part according to the invention consists of a base body, which is for receiving of the clamp is suitable. This can be through a through hole or each other Opposing blind holes can be reached through either the bracket passed through or into which the bracket is hooked. The basic body can be made of any suitable material, with a ceramic material such as e.g. Porcelain, a porcelain substitute or glass is suitable. These materials have that Advantage that they are easy to print and give the consumer the impression of a convey conventional clip lock.

Das erfindungsgemäße Verschlussteil besteht dann weiter aus einem zumindest teilweise in die Flaschenmündung eintauchenden Dichtungsabschnitt. Der Dichtungsabschnitt besteht aus zwei Bereichen, nämlich einem Bereich aus einem elastischen Material, der in geschlossenem Zustand der Flasche die Anlagefläche an der Flaschenmündung bildet, und einem nicht elastischen Bereich, der im geschlossenen Zustand nicht mit der Flaschenmündung in Berührung kommt. Der elastische Bereich umschließt den nicht elastischen Bereich ringförmig.The closure part according to the invention then consists of an at least partially in the sealing portion immersing the bottle mouth. The sealing section is made of two areas, namely an area made of an elastic material, which in closed state of the bottle forms the contact surface at the bottle mouth, and a non-elastic area which, when closed, does not match the Bottle mouth comes into contact. The elastic area does not enclose it elastic area ring-shaped.

Das vollständige Verschlussteil wird dann zum Schließen der Flasche so auf die Mündung aufgesetzt, dass der elastische Bereich in Anlage mit der Flaschenmündung kommt, und durch den Bügel gespannt wird. Der elastische Bereich dient dann zur Abdichtung des Verschlussteils gegen die Flaschenmündung, während der nicht elastische Teil die Gasdichtigkeit des Verschlusses sicherstellt.The complete closure part is then used to close the bottle on the mouth put on that the elastic area comes into contact with the bottle mouth, and is tensioned by the bracket. The elastic region then serves to seal the Closure part against the bottle mouth, while the non-elastic part Ensures gas tightness of the closure.

Grundkörper und Dichtungsabschnitt sind durch eine Klemmverbindung miteinander verbunden. Der Dichtungsabschnitt des erfindungsgemäßen Verschlussteils wird im Zweikomponenten-Spritzverfahren hergestellt. Base body and sealing section are interconnected by a clamp connection connected. The sealing section of the closure part according to the invention is in the Two-component spraying process.

Vorzugsweise besteht der Dichtungsabschnitt aus zwei unterschiedlichen Kunststoffen. Für den elastischen Bereich des Dichtungsabschnitts kann insbesondere ein thermoplastisches Elastomermaterial verwendet werden, während der nicht elastische Bereich des Dichtungsabschnittes vorzugsweise aus Polyethylen (PE), Polypropylen (PP) oder Polyoxymethylen (POM) besteht.The sealing section preferably consists of two different plastics. For the elastic region of the sealing section can in particular be a thermoplastic Elastomeric material can be used while the non-elastic area of the Sealing section preferably made of polyethylene (PE), polypropylene (PP) or Polyoxymethylene (POM) is made.

Vorteil des erfindungsgemäßen Verschlussteils ist die vollständige Abdichtung der verschlossenen Flasche durch den Dichtungsabschnitt aus Kunststoff, wohingegen nach außen der Eindruck eines herkömmlichen keramischen Verschlussteils vermittelt wird.The advantage of the closure part according to the invention is the complete sealing of the sealed bottle through the sealing portion made of plastic, whereas the impression of a conventional ceramic closure part is conveyed to the outside.

Der Grundkörper kann vorzugsweise einen hohen Glasanteil aufweisen, um Wertstoffrecycling zu erleichtern. Glasanteile von 20% oder mehr sind besonders vorteilhaft. Gegenüber den herkömmlichen Verschlusskörpern, die vollständig aus Kunststoff bestehen, treten beim Recycling aufgrund des reduzierten Kunststoffanteils des erfindungsgemäßen Verschlussteils weniger Probleme mit Fremdmaterialien auf.The base body can preferably have a high proportion of glass in order to Facilitate recycling of materials. Glass contents of 20% or more are particularly advantageous. Compared to the conventional closure bodies, which are made entirely of plastic, occur during recycling due to the reduced plastic content of the invention Closure part less problems with foreign materials.

Die Erfindung wird im Folgenden anhand der beigefügten Abbildung näher erläutert:

Fig. 1
zeigt ein erfindungsgemäßes Verschlussteil im Querschnitt.
Fig. 2
zeigt eine alternative Ausführungsform des erfindungsgemäßen Verschlussteils im Querschnitt.
The invention is explained in more detail below with the aid of the attached figure:
Fig. 1
shows a closure part according to the invention in cross section.
Fig. 2
shows an alternative embodiment of the closure part according to the invention in cross section.

Das in Fig. 1 dargestellte Verschlussteil besteht aus einem Grundkörper 1, der zur Aufnahme eines Spannbügels mit einer Bohrung 5 versehen ist. Der Grundkörper 1 verfügt über eine Nase 6, auf der der zweikomponentige Dichtungsabschnitt 2 angebracht ist.The closure part shown in Fig. 1 consists of a base body 1 which is provided with a bore 5 for receiving a clamping bracket. The base body 1 has a nose 6 , on which the two-component sealing section 2 is attached.

Der Dichtungsabschnitt 2 besteht aus einem nicht elastischen Bereich 4, der in geschlossenem Zustand der Flasche zumindest teilweise in den Flaschenhals eingeführt ist und nicht mit diesem in Berührung kommt. Auf dem nichtelastischen Bereich 4 ist ringförmig der elastische Bereich 3 angeordnet, der die Anlagefläche an der Flaschenmündung bildet. Der nichtelastische Bereich 4 ragt im Ringinnern über den elastischen Bereich 3 hinaus. Dadurch wird erreicht, dass der empfindliche elastische Bereich 3 vom vorstehenden nichtelastischen Bereich 4 geschützt wird, wenn die Flasche beim Mehrwegeeinsatz offen zurücktransportiert wird. Das Verschlussteil liegt dann normalerweise mit seiner Oberseite am Flaschenhals an, so dass der Dichtungsabschnitt 2 seitlich absteht. Schnitte und Abschürfungen im elastischen Bereich 3 können die Dichtwirkung des Verschlußteils nach der Neubefüllung beeinträchtigen und sind schwerer zu reinigen.The sealing section 2 consists of a non-elastic region 4 which , when the bottle is closed, is at least partially inserted into the bottle neck and does not come into contact with it. The elastic area 3 , which forms the contact surface at the bottle mouth, is arranged in a ring on the non-elastic area 4 . The non-elastic region 4 projects beyond the elastic region 3 in the interior of the ring. It is thereby achieved that the sensitive elastic region 3 is protected from the above non-elastic region 4 when the bottle is openly transported back in the case of reusable use. The closure part then normally rests with its top against the bottle neck, so that the sealing section 2 protrudes laterally. Cuts and abrasions in the elastic area 3 can impair the sealing effect of the closure part after refilling and are more difficult to clean.

Der Dichtungsabschnitt 2 wird im Zweikomponenten-Spritzverfahren hergestellt und anschließend auf die Nase 6 des Grundkörpers 1 geklemmt. Er greift hinter die umlaufende Nut der Nase 6. Dadurch wird eine sichere Verbindung geschaffen, die zum Recycling einer Flasche wieder getrennt und der Kunststoffanteil gesondert wiederverwertet werden kann.The sealing section 2 is produced in a two-component injection molding process and then clamped onto the nose 6 of the base body 1 . It reaches behind the circumferential groove of the nose 6 . This creates a secure connection that can be separated for recycling a bottle and the plastic portion can be recycled separately.

Der nicht elastische Bereich 4 des Dichtungsabschnitts 2 ist dadurch gut mit dem Grundkörper 1 verbunden. Die Nase 6 des Grundkörpers 1 kann alternativ zu der in Fig. 1 gezeigten Ausführung auch so beschaffen sein, daß der nicht elastische Bereich 4 praktisch eine Beschichtung von annähernd gleichmäßiger Dicke darstellt.The non-elastic region 4 of the sealing section 2 is thus well connected to the base body 1 . As an alternative to the embodiment shown in FIG. 1, the nose 6 of the base body 1 can also be such that the non-elastic region 4 practically represents a coating of approximately uniform thickness.

Der Grundkörper 1 besteht aus einem keramischen Material mit hohem Glasanteil, um das Recycling zu vereinfachenThe base body 1 consists of a ceramic material with a high glass content in order to simplify recycling

Nach außen hin entsteht der Eindruck eines herkömmlichen keramischen Verschlußkörpers. Dies schätzen die Kunden aufgrund des charakteristischen Griffgefühls eines herkömmlichen Bügelverschlusses insbesondere.On the outside, the impression of a conventional ceramic is created Closure body. Customers appreciate this because of the characteristic Grip feeling of a conventional clip closure in particular.

Fig. 2 zeigt eine andere Ausführungsform eines öffnungsgemäßen Verschlußteils ebenfalls im Querschnitt. Der Grundkörper 1 weist wiederum eine Bohrung 5 zur Aufnahme des Spannbügels auf. Die Nase des Grundkörpers wird ebenfalls vom zweikomponentigen Dichtungsabschnitt 2 umspannt. Im Bereich der Anlagefläche der Flaschenmündung ist der nichtelastische Bereich 4 mit elastischem Material 3 versehen. Fig. 2 shows another embodiment of an opening-like closure part also in cross section. The base body 1 in turn has a bore 5 for receiving the clamping bracket. The nose of the base body is also spanned by the two-component sealing section 2 . In the area of the contact surface of the bottle mouth, the non-elastic area 4 is provided with elastic material 3 .

Der nichtelastische Bereich 4 des Dichtungsabschnitts 2 reicht bis zum Rand des Grundkörpers 1, so daß der elastische Bereich 3 keine Dichtwirkung zum Grundkörper 1 herbeiführen kann. Kommt es zu einer Beschädigung des nicht elastischen Bereichs 4 des Dichtungsabschnitts 2, so kann das in der Flasche abgefüllte Getränk, insbesondere Bier, durch den Dichtungsabschnitt 2 hindurch in den Zwischenraum zwischen Dichtungsabschnitt und Grundkörper eindringen und an der Fuge zwischen beiden Teilen austreten. Ein beschädigter Dichtungsabschnitt kann deshalb in der Abfüllung mit herkömmlichen Abfüllmaschnienn sofort festgestellt werden.The non-elastic region 4 of the sealing section 2 extends to the edge of the base body 1 , so that the elastic region 3 can not bring about a sealing effect on the base body 1 . If the non-elastic region 4 of the sealing section 2 is damaged, the beverage filled in the bottle, in particular beer, can penetrate through the sealing section 2 into the space between the sealing section and the base body and emerge at the joint between the two parts. A damaged sealing section can therefore be immediately identified in the filling with conventional filling machines.
