Description

Die Erfindung betrifft ein Verschlusselement für Flaschen gemäß Oberbegriff des Anspruchs 1.The invention relates to a closure element for bottles according to the preamble of claim 1.

Verschlusselemente der hier angesprochenen Art sind bekannt. Sie werden insbesondere bei Flaschen mit hochwertigem Inhalt verwendet, besonders solchen aus Glas. Um einen dichten Abschluss des Inhalts der Flaschen zu gewährleisten, wird ein Dichtungselement vorgesehen. Nach dem Verschließen beim Hersteller werden Verschlusselemente der hier angesprochenen Art in der Regel gesichert, beispielsweise durch eine Kunststoff- oder Aluminiumkappe, die das Verschlusselement auf der Flasche hält. Nach dem ersten Öffnen, also auch dem Entfernen der Kappe, hält sich das Verschlusselement mittels der zwischen Dichtungselement und Flasche herrschenden Reibung. Bei einer Druckerhöhung im Inneren der Flasche kann es daher geschehen, dass das Verschlusselement so weit aus dem Mündungsbereich der Flasche herausgeschoben wird, dass es seinen Halt verliert und gegebenenfalls ganz abfällt.Closure elements of the type discussed here are known. They are used especially for bottles with high quality content, especially those made of glass. In order to ensure a tight closure of the contents of the bottles, a sealing element is provided. After sealing with the manufacturer closure elements of the type mentioned here are usually secured, for example by a plastic or aluminum cap that holds the closure element on the bottle. After the first opening, thus also the removal of the cap, the closure element holds itself by means of the friction between the sealing element and the bottle. With an increase in pressure inside the bottle, it may therefore happen that the closure element is pushed so far out of the mouth region of the bottle that it loses its grip and possibly falls completely.

Aufgabe der Erfindung ist es daher, ein Verschlusselement für Flaschen zu schaffen, das diesen Nachteil nicht aufweist.The object of the invention is therefore to provide a closure element for bottles, which does not have this disadvantage.

Zur Lösung dieser Aufgabe wird ein Verschlusselement vorgeschlagen, das die in Anspruch 1 genannten Merkmale zeigt. Es weist einen in die Mündung der Getränkeflasche eingreifenden Stopfen und einen Kopf mit einem Außendurchmesser auf, der größer ist als der des Stopfens. Ein Dichtungselement, des im Übergangsbereich zwischen Stopfen und Kopf angeordnet ist, weist einen ersten Dichtungsbereich auf, der am Stopfen anliegt. Der Innenraum der Getränkeflasche wird durch mindestens einen nach außen weisenden Dichtwulst abgeschlossen, der im ersten Dichtungsbereich vorgesehen ist. Das Verschlusselement zeichnet sich dadurch aus, dass auf der dem Kopf abgewandten Seite des Dichtwulsts in einem Abstand zu diesem mindestens ein nach außen vorspringender Vorsprung vorgesehen ist, vorzugsweise ein ringförmiger Wulst, der mindestens einen in die Umfangsfläche des Wulsts eingebrachte Ausnehmung aufweist, und dass der erste Dichtungsbereich auf seiner dem Stopfen zugewandten Innenseite mindestens einen Vorsprung, vorzugsweise einen Innenwulst aufweist.To solve this problem, a closure element is proposed, which shows the features mentioned in claim 1. It has a stopper engaging in the mouth of the beverage bottle and a head with an outside diameter larger than that of the stopper. A sealing element in the transition area between Plug and head is arranged, has a first sealing area, which abuts the plug. The interior of the beverage bottle is closed by at least one outwardly facing sealing bead, which is provided in the first sealing area. The closure element is characterized in that on the side facing away from the head of the sealing bead is provided at a distance to this at least one outwardly projecting projection, preferably an annular bead having at least one introduced into the peripheral surface of the bead recess, and that first sealing region on its side facing the plug inside at least one projection, preferably an inner bead has.

Hierdurch werden zusätzliche Haltekräfte zwischen Verschlusselement und Flasche aufgebaut. Bei einem Überdruck in der Flasche wird das Verschlusselement etwas aus der Mündung der Flasche heraus geschoben, nämlich so weit, bis der als Dichtung wirkende Dichtwulst so weit aus der Mündung der Flasche heraus geschoben wird, dass er deren Innenraum nicht mehr abschließt und der Überdruck entweichen kann. Durch den mindestens einen in einem Abstand zu dem Dichtwulst liegenden Vorsprung beziehungsweise durch die Aussparung in dem ringförmigen Wulst kann der Innendruck aus der Flasche entweichen. Gleichzeitig ist sichergestellt, dass das Verschlusselement auf der Flasche noch ausreichend Halt findet und nicht aus der Mündung herausfallen kann.As a result, additional holding forces between closure element and bottle are built. At an overpressure in the bottle, the closure element is slightly pushed out of the mouth of the bottle, namely so far, until the seal acting as a sealing bead is pushed so far out of the mouth of the bottle that he no longer completes its interior and escape the pressure can. By the at least one projection lying at a distance from the sealing bead or by the recess in the annular bead, the internal pressure can escape from the bottle. At the same time it is ensured that the closure element on the bottle still finds sufficient support and can not fall out of the mouth.

Weitere Ausgestaltungen ergeben sich aus den Unteransprüchen.Further embodiments emerge from the subclaims.

Die Erfindung wird im Folgenden anhand der Zeichnung näher erläutert. Die einzige Figur zeigt eine Prinzipskizze eines Verschlusselements in Seitenansicht mit einem Dichtelement im Längsschnitt.The invention will be explained in more detail below with reference to the drawing. The single FIGURE shows a schematic diagram of a closure element in side view with a sealing element in longitudinal section.

Das dargestellte Verschlusselement 1 weist einen Stopfen 3 auf, der in die Mündung einer Flasche einführbar ist. An den Stopfen schließt sich ein Kopf 5 an, dessen Außendurchmesser größer ist als der des Stopfens 3. Beispielsweise kann vorgesehen werden, dass der Außendurchmesser des Kopfs 5 im Wesentlichen dem der Flasche im Mündungsbereich entspricht, so dass die Flasche quasi in das Verschlusselement übergeht. Stopfen 3 und Kopf 5 sind vorzugsweise einstückig ausgebildet.The closure element 1 shown has a plug 3, which is insertable into the mouth of a bottle. Close to the stopper For example, it can be provided that the outer diameter of the head 5 substantially corresponds to that of the bottle in the mouth region, so that the bottle virtually merges into the closure element. Plug 3 and head 5 are preferably formed in one piece.

Im Übergangsbereich zwischen Stopfen 3 und Kopf 5 ist ein Dichtungselement 7 vorgesehen, das zumindest einen am Stopfen 3 anliegenden ersten Dichtungsbereich 9 aufweist. Vorzugsweise ist, wie in der Figur dargestellt, ein sich daran anschließender zweiter Dichtungsbereich 11 vorgesehen, der von unten am Kopf 5 anliegt.In the transition region between the plug 3 and the head 5, a sealing element 7 is provided which has at least one first sealing area 9 resting against the stopper 3. Preferably, as shown in the figure, an adjoining second sealing region 11 is provided, which bears against the head 5 from below.

Auf der dem Stopfen 3 abgewandten Außenseite des ersten Dichtungsbereichs 9 ist hier ein Dichtwulst 13 vorgesehen, der den Innenraum einer Flasche gegenüber der Umgebung abdichtet. Es ist möglich, mehrere derartiger Dichtwulste übereinander, also in einem Abstand zueinander vorzusehen. Auf der dem Kopf 5 abgewandten Seite des Dichtwulstes 13 ist hier ein ringförmiger Wulst 15 vorgesehen, der in seiner Umfangsfläche mindestens eine Ausnehmung aufweist, die den Innenraum der Flasche gegenüber dem Dichtwulst 13 nicht abdichtet, also einen Durchlass darstellt. Im Innenraum der Flasche wirkender Druck kann also weiterhin auf den Dichtwulst 13 wirken.On the outside of the first sealing region 9 facing away from the plug 3, a sealing bead 13 is provided here, which seals the interior of a bottle from the environment. It is possible to provide a plurality of such sealing beads one above the other, ie at a distance from one another. On the side facing away from the head 5 of the sealing bead 13 here is an annular bead 15 is provided, which has at least one recess in its peripheral surface, which does not seal the interior of the bottle against the sealing bead 13, so represents a passage. In the interior of the bottle acting pressure can thus continue to act on the sealing bead 13.

Anstelle des Wulsts 15 kann auch mindestens ein Vorsprung, vorzugsweise eine Anzahl von Vorsprüngen vorgesehen werden, die auf einer gedachten Umfangslinie in einem Abstand zueinander angeordnet sind und den Innenraum der Flasche gegenüber dem Dichtwulst 13 nicht druckdicht abschließen.Instead of the bead 15 and at least one projection, preferably a number of projections may be provided which are arranged on an imaginary circumferential line at a distance from each other and not seal the interior of the bottle against the sealing bead 13 pressure-tight.

Auf der dem Stopfen 3 zugewandten Seite des ersten Dichtungsbereichs 9 ist ein Innenwulst 17 vorgesehen, der im unteren Bereich des Dichtwulstes 13 vorgesehen ist, aber in Richtung der Mittelachse 19 des Verschlusselements 1 gesehen eine geringere Ausdehnung und eine kleinere Höhe aufweist. Der Innenwulst 17 dient als Stütze für den Dichtwulst 13 und als Halt des Dichtungselements 7 auf dem Stopfen 3.On the plug 3 facing side of the first sealing portion 9, an inner bead 17 is provided which is provided in the lower region of the sealing bead 13, but seen in the direction of the central axis 19 of the closure element 1 has a smaller extent and a smaller height. The inner bead 17 serves as a support for the sealing bead 13 and as a stop of the sealing element 7 on the plug. 3

Zusätzlich kann im Bereich des Wulsts 15 beziehungsweise des hier vorgesehenen mindestens einen Vorsprungs ebenfalls ein Innenwulst vorgesehen werden. Abmessung und Anzahl des mindestens einen Innenwulsts 17 können an verschiedene Anwendungsfälle angepasst werden.In addition, an inner bead can likewise be provided in the region of the bead 15 or of the at least one projection provided here. Dimension and number of at least one Innenwulsts 17 can be adapted to different applications.

Auf der dem Kopf 5 abgewandten Unterseite des zweiten Dichtungsbereichs 11 ist mindestens ein konzentrisch zur Mittelachse 19 verlaufender Ringwulst 21 vorgesehen. Bei dem hier dargestellten Ausführungsbeispiel sind zwei konzentrisch zueinander angeordnete Ringwulste 21 und 23 dargestellt. Diese können als zusätzliche Dichtung dienen, aber auch dazu, einen Stoß auf das Verschlusselement 1 federnd abzufangen, während dieses auf eine Flasche aufgesetzt ist und sich mit den Ringwulsten 21, 23 an dem die Mündung umgebenden Wandbereich der Flasche abstützt.On the side facing away from the head 5 bottom of the second sealing portion 11 at least one concentric with the central axis 19 extending annular bead 21 is provided. In the embodiment shown here, two concentrically arranged annular beads 21 and 23 are shown. These can serve as an additional seal, but also to intercept a shock on the closure element 1 resiliently, while this is placed on a bottle and with the annular beads 21, 23 is supported on the wall region surrounding the mouth of the bottle.

Zur Funktion des Verschlusselements 1 ist Folgendes festzuhalten:For the function of the closure element 1, the following must be stated:

Zum Verschließen einer Flasche wird das Verschlusselement 1 auf eine Flasche aufgesetzt, so dass der Stopfen 3 in die Mündung derselben eingreift und der Kopf 5 sich auf dem Wandbereich der Flasche abstützt, der die Mündung umgibt. Das Dichtungselement 7 dient dazu, den Innenraum der Flasche dicht abzuschließen, wobei zumindest ein erster Dichtungsbereich 9 im Bereich des Stopfens 3 für den Abschluss sorgt. Zusätzlich kann noch ein zweiter Dichtungsbereich 11 vorgesehen werden. Bevorzugt ist das Dichtungselement 7 einstückig ausgebildet, so dass der erste Dichtungsbereich 9 in den zweiten Dichtungsbereich 11 übergeht. Der erste Dichtungsbereich 9 ist im Wesentlichen zylindrisch oder leicht konisch ausgebildet und liegt konzentrisch zur Mittelachse 19. Der zweite Dichtungsbereich 11 liegt in einer Ebene, auf der die Mittelachse 19 senkrecht steht.To close a bottle, the closure element 1 is placed on a bottle, so that the plug 3 engages in the mouth of the same and the head 5 is supported on the wall portion of the bottle surrounding the mouth. The sealing member 7 serves to seal the interior of the bottle, wherein at least a first sealing region 9 in the region of the plug 3 ensures the conclusion. In addition, a second sealing region 11 may be provided. Preferably, the sealing element 7 is integrally formed, so that the first sealing region 9 merges into the second sealing region 11. The first sealing region 9 is substantially cylindrical or slightly conical and is concentric with the central axis 19. The second sealing region 11 lies in a plane on which the central axis 19 is perpendicular.

Für den dichten Abschluss des Innenraums der Flasche sorgt der Dichtwulst 13. Er liefert in der Regel auch ausreichende Haltekräfte, um das Verschlusselement 1 auf einer Flasche zu halten. Zusätzliche Haltekräfte werden durch den, vom Kopf 5 aus gesehen, unterhalb des Dichtwulstes 13 angeordneten mindestens einen Vorsprung beziehungsweise durch den Wulst 15 aufgebaut. Wesentlich ist, dass hier jedoch eine Dichtung des Innenraums der Flasche nicht gegeben ist, so dass ein sich hier aufbauender Druck bis zu dem Dichtwulst 13 wirkt.For the tight completion of the interior of the bottle provides the sealing bead 13. He also provides sufficient holding forces to hold the closure element 1 on a bottle in the rule. Additional holding forces are constructed by the, viewed from the head 5, below the sealing bead 13 arranged at least one projection or by the bead 15. It is essential that, however, a seal of the interior of the bottle is not given here, so that a pressure building up here acts up to the sealing bead 13.

Baut sich also im Inneren der Flasche ein Druck auf, wird der Stopfen 3 etwas aus der Mündung derselben heraus gedrückt, und zwar so weit, bis der Überdruck am Dichtwulst 13 vorbei entweichen kann. In dieser Position findet das Verschlusselement 1 in der Mündung einer Flasche noch ausreichend Halt, weil unterhalb des Dichtwulstes 13 noch mindestens ein Vorsprung, vorzugsweise der Wulst 15 vorgesehen ist. Da dieser mit mindestens einer Ausnehmung versehen ist, kann der Innendruck in der Flasche hier entweichen, so dass eine weitere axiale Verlagerung des Verschlusselements 1 aus der Flasche heraus nicht stattfindet.Thus, if pressure builds up inside the bottle, the plug 3 is pushed out of the mouth of the plug somewhat, until the overpressure at the sealing bead 13 can escape. In this position, the closure element 1 still finds sufficient hold in the mouth of a bottle, because below the sealing bead 13 at least one projection, preferably the bead 15 is provided. Since this is provided with at least one recess, the internal pressure in the bottle can escape here, so that a further axial displacement of the closure element 1 out of the bottle does not take place.

Während im ursprünglich verschlossenen Zustand der Kopf 5 des Verschlusselements 1 praktisch ganz auf der die Mündung umgebenden Wand einer Flasche aufliegt, nämlich in einem durch das zweite Dichtelement 11 vorgegebenen Abstand, befindet sich das Verschlusselement nach Abbau eines erhöhten Innendrucks im Innenraum in einer Position, in der der Abstand zwischen dem Kopf 5 und der Flasche vergrößert ist. Allein daran kann ein Verbraucher erkennen, dass das Verschlusselement durch Innendruck in der Flasche verschoben wurde. Diese Verlagerung könnte bei einem nicht gasenden Inhalt als Indiz dafür herangezogen werden, dass der Inhalt verdorben ist und gärt.While in the originally closed state, the head 5 of the closure element 1 practically completely rests on the wall surrounding the mouth of a bottle, namely in a predetermined by the second sealing element 11 distance, the closure element is located after reducing an increased internal pressure in the interior in a position in the distance between the head 5 and the bottle is increased. Only a consumer can recognize that the closure element has been displaced by internal pressure in the bottle. This shift could be used as an indication of non-gassing content that the content is spoiled and is fermenting.

Das Verschlusselement 1 besteht vorzugsweise ganz aus Glas, so dass es den Inhalt in der Flasche geschmacklich nicht beeinträchtigt. Es würde reichen, lediglich den Stopfen aus Glas herzustellen, zumindest die Bereiche, die mit dem Inhalt der Flasche in Berührung kommen. Das Verschlusselement 1 kann jedoch auch aus Metall, Keramik und aus einem Kunststoff bestehen, der den Inhalt der Flasche geschmacklich nicht beeinträchtigt. Entsprechend wird für das Dichtungselement 7 ein Kunststoff gewählt, der einerseits ausreichend elastisch ist, um ein Abdichten des Innenraums der Flasche zu gewährleisten, andererseits aber dem Verschlusselement 1 ausreichend Halt auf der Flasche liefert und den Inhalt ebenfalls nicht geschmacklich beeinträchtigt.The closure element 1 is preferably made entirely of glass, so that it does not affect the content in the bottle flavor. It would be enough to make only the plug of glass, at least the areas that come in contact with the contents of the bottle. However, the closure element 1 may also consist of metal, ceramic and a plastic, which does not affect the content of the bottle in taste. Accordingly, a plastic is selected for the sealing element 7, which on the one hand is sufficiently elastic to ensure a sealing of the interior of the bottle, but on the other hand, the closure element 1 provides sufficient support on the bottle and also does not affect the content of the taste.

Es ist im Übrigen möglich, das Verschlusselement 1 aus Glas, Metall oder Keramik herzustellen und mit einer Kunststoffbeschichtung zu versehen, die das Dichtungselement 7 realisiert und eine Außenkontur aufweist, wie sie beim Dichtungselement 7 vorgesehen ist.It is otherwise possible to produce the closure element 1 made of glass, metal or ceramic and provided with a plastic coating which realizes the sealing element 7 and has an outer contour, as provided in the sealing element 7.

Das Funktionsprinzip des Verschlusselements 1 macht deutlich, dass das Dichtungselement 7 mindestens einen den Innenraum einer Flasche abdichtenden Dichtwulst 13 aufweist, außerdem noch einen Haltebereich, der das Verschlusselement 1 auch nach einer Verlagerung desselben in Richtung der Mittelachse 19 sicher auf einer Flasche hält. Um diese Funktion zu gewährleisten, ist unterhalb des Dichtwulsts 13, also auf der dem Kopf 5 abgewandten Seite, mindestens ein Vorsprung vorgesehen, der das Verschlusselement 1 im Mündungsbereich einer Flasche halten kann. Vorzugsweise sind jedoch mehrere Vorsprünge, insbesondere aber ein umlaufender Wulst 15 mit mindestens einer Ausnehmung vorgesehen, der dem Verschlusselement 1 auch dann sicheren Halt in der Mündung einer Flasche bietet, wenn das Verschlusselement 1 etwas in Richtung der Mittelachse 19 verschoben wurde.The principle of operation of the closure element 1 makes it clear that the sealing element 7 has at least one sealing bead 13 sealing the interior of a bottle, and also a holding region which securely holds the closure element 1 on a bottle even after a displacement thereof in the direction of the central axis 19. To ensure this function, at least one projection is provided below the sealing bead 13, that is, on the side facing away from the head 5, which can hold the closure element 1 in the mouth region of a bottle. Preferably, however, a plurality of projections, but in particular a circumferential bead 15 are provided with at least one recess, which also provides the closure element 1 secure hold in the mouth of a bottle when the closure element 1 has been slightly shifted in the direction of the central axis 19.
