Beschreibungdescription
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 gesi- chert, 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. Aufgabe der Erfindung ist es daher, ein Verschlusselement für Flaschen zu schaffen, das diesen Nachteil nicht aufweist.Closure elements of the type mentioned here are known. They are used in particular in bottles with high-quality contents, especially those made of glass. A sealing element is provided to ensure that the contents of the bottles are sealed. After closure at the manufacturer, closure elements of the type mentioned here are generally secured, for example by a plastic or aluminum cap that holds the closure element on the bottle. After the first opening, ie also the removal of the cap, the closure element is held in place by the friction prevailing between the sealing element and the bottle. If the pressure inside the bottle rises, it can therefore happen that the closure element is pushed out of the mouth area of the bottle so that it loses its hold and possibly falls off completely. 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, das im Übergangsbereich zwi- sehen Stopfen und Kopf angeordnet ist, weist einen ersten Dichtungsbereich auf, der am .Stopfen anliegt. Der Innenraum der Ge- tränkeflasche 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 ersten Dichtungsbereichs mindestens ein nach außen vorspringender Vorsprung vorgesehen ist, vorzugsweise ein ringförmiger Wulst, der mindestens einen in die Umfangsfläche des Wülsts eingebrachte Ausnehmung aufweist.To solve this problem, a closure element is proposed, which shows the features mentioned in claim 1. It has a stopper which engages in the mouth of the beverage bottle and a head with an outer diameter which is larger than that of the stopper. A sealing element, which is arranged in the transition area between the stopper and the head, has a first sealing area which rests on the stopper. The interior of the Drinking bottle is closed by at least one outward-pointing sealing bead, which is provided in the first sealing area. The closure element is characterized in that at least one outwardly projecting projection is provided on the side of the first sealing region facing away from the head, preferably an annular bead which has at least one recess made in the peripheral surface of the bead.
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 Ab- stand 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 JHalt findet und nicht aus der Mündung herausfallen kann.This creates additional holding forces between the closure element and the bottle. If there is overpressure in the bottle, the closure element is pushed somewhat out of the mouth of the bottle, namely until the sealing bead, which acts as a seal, is pushed so far out of the mouth of the bottle that it no longer closes the interior and the excess pressure escapes can. The internal pressure can escape from the bottle through the at least one projection located at a distance from the sealing bead or through the recess in the annular bead. At the same time, it is ensured that the closure element on the bottle still finds sufficient hold and cannot fall out of the mouth.
Weitere Ausgestaltungen ergeben sich aus den Unteransprüchen.Further refinements result 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 is 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 desThe illustrated closure element 1 has a stopper 3 which can be inserted into the mouth of a bottle. A head 5 adjoins the stopper, the outer diameter of which is larger than that of the
Stopfens 3. Beispielsweise kann vorgesehen werden, dass der Au- ßendurchmesser 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. 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.Stopper 3. For example, it can be provided that the outer The outer diameter of the head 5 essentially corresponds to that of the bottle in the mouth area, so that the bottle virtually passes into the closure element. Plug 3 and head 5 are preferably formed in one piece. In the transition area between the plug 3 and the head 5, a sealing element 7 is provided, which has at least one first sealing area 9 resting on the plug 3. Preferably, as shown in the figure, a second sealing region 11 adjoining it 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 Djchtwulste 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 stopper 3, a sealing bead 13 is provided here, which seals the interior of a bottle from the surroundings. It is possible to provide several such ridges on top of each other, that is, at a distance from one another. On the side of the sealing bead 13 facing away from the head 5, an annular bead 15 is provided here, which has at least one recess in its circumferential surface, which does not seal the interior of the bottle from the sealing bead 13, that is to say represents a passage. Pressure acting in the interior of the bottle can therefore continue to act on the sealing bead 13.
Anstelle des Wülsts 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 it is also possible to provide at least one projection, preferably a number of projections, which are arranged at a distance from one another on an imaginary circumferential line and do not seal the interior of the bottle from the sealing bead 13 in a pressure-tight manner.
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.An inner bead 17 is provided on the side of the first sealing region 9 facing the stopper 3, which is in the lower region of the sealing bead 13 is provided, but has a smaller extent and a smaller height when viewed in the direction of the central axis 19 of the closure element 1. The inner bead 17 serves as a support for the sealing bead 13 and as a support for the sealing element 7 on the stopper 3.
Zusätzlich kann im Bereich des Wülsts 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 an- gepasst werden.In addition, an inner bead can also be provided in the region of the bead 15 or the at least one projection provided here. The dimension and number of the at least one inner bead 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 underside of the second sealing region 11 facing away from the head 5, at least one annular bead 21 running concentrically to the central axis 19 is provided. In the exemplary embodiment shown here, two annular beads 21 and 23 arranged concentrically to one another are shown. These can serve as an additional seal, but also to resiliently absorb an impact on the closure element 1 while it is placed on a bottle and is supported with the annular beads 21, 23 on the wall area of the bottle surrounding the mouth.
Zur Funktion des Verschlusselements 1 ist Folgendes festzuhalten:The following should be noted regarding the function of the closure element 1:
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 Dich- tungsbereich 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 stopper 3 engages in the mouth thereof and the head 5 is supported on the wall area of the bottle that surrounds the mouth. The sealing element 7 serves to seal off the interior of the bottle, at least a first sealing area 9 in the area of the stopper 3 ensuring the closure. In addition, a second seal tion area 11 are provided. The sealing element 7 is preferably formed in one piece, so that the first sealing area 9 merges into the second sealing area 11. The first sealing area 9 is essentially cylindrical or slightly conical and is concentric with the central axis 19. The second sealing area 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.The sealing bead 13 ensures the tight closure of the interior of the bottle. As a rule, it also provides sufficient holding forces to hold the closure element 1 on a bottle. Additional holding forces are built up by the at least one projection, as seen from the head 5, below the sealing bead 13 or by the bead 15. It is essential that there is no seal of the interior of the bottle here, so that a pressure that builds 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. 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.If a pressure builds up inside the bottle, the stopper 3 is pushed out of the mouth of the stopper until the overpressure can escape past the sealing bead 13. In this position, the closure element 1 still finds sufficient hold in the mouth of a bottle, because at least one projection, preferably the bead 15, is provided below the sealing bead 13. Since this is provided with at least one recess, the internal pressure in the bottle can escape here, so that there is no further axial displacement of the closure element 1 out of the bottle. While in the originally closed state, the head 5 of the closure element 1 rests practically entirely on the wall of a bottle surrounding the mouth, namely at a distance predetermined by the second sealing element 11, the closure element is in a position after removal of an increased internal pressure in the interior which increases the distance between the head 5 and the bottle. This alone shows a consumer that the closure element has been displaced in the bottle due to internal pressure. In the case of non-gassing content, this shift could be used as an indication that the content has 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, zu- mindest 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 ausrei- chend 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 taste of the contents in the bottle. It would be enough to simply make the stopper out of glass, at least the areas that come into contact with the contents of the bottle. However, the closure element 1 can also consist of metal, ceramic and a plastic which does not impair the taste of the contents of the bottle. Accordingly, for. the sealing element 7 selected a plastic which on the one hand is sufficiently elastic to ensure that the interior of the bottle is sealed, but on the other hand provides the closure element 1 with sufficient hold on the bottle and likewise does not impair the taste of the contents.
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. 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 Veriagerμng 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. Incidentally, it is possible to produce the closure element 1 from glass, metal or ceramic and to provide it with a plastic coating which realizes the sealing element 7 and has an outer contour, as is provided for the sealing element 7. The functional principle of the closure element 1 makes it clear that the sealing element 7 has at least one sealing bead 13 which seals the interior of a bottle, and also a holding area which holds the closure element 1 securely on a bottle even after it has been displaced in the direction of the central axis 19. In order to ensure this function, at least one projection is provided below the sealing bead 13, ie 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 with at least one recess is provided, which also offers the closure element 1 a secure hold in the mouth of a bottle when the closure element 1 has been displaced somewhat in the direction of the central axis 19.
