Description

Die vorliegende Erfindung betrifft einen Behälterverschluss, der zwei Hauptbestandteile umfasst, nämlich einen aus Kunststoff bestehenden Flansch, welcher an einer Öffnungsfläche eines Behälters befestigt werden kann, und weiterhin einen Deckel, der lösbar an einer Abgabeöffnung des Flansches angebracht ist.The present invention relates to a container closure comprising two main components, namely a plastic flange, which can be fixed to an opening surface of a container, and further a lid, which is detachably attached to a discharge opening of the flange.

Die Erfindung betrifft darüber hinaus einen Behälter, insbesondere eine Getränkedose bzw. einen vergleichbaren Flüssigkeitsbehälter mit einem solchen Behälterverschluss.The invention further relates to a container, in particular a beverage can or a comparable liquid container with such a container closure.

Insbesondere bei Getränkedosen aber auch bei anderen Behältern, die vorzugsweise Flüssigkeiten enthalten, können wieder verschließbare, gut dichtende Behälterverschlüsse entweder gar nicht oder nur mit erheblichem Aufwand angebracht werden. Natürlich ist es möglich, insbesondere an Kunststoffbehältern eine verschließbare Ausgabeöffnung herstellerseitig vorzusehen, wodurch die Komplexität der regelmäßig verwendeten Spritzgussformen allerdings steigt und damit auch die Herstellungskosten höher sind. Bei Massenprodukten, wie beispielsweise den herkömmlichen metallischen Getränkedosen sind die Herstellungskosten ein wesentliches Kriterium, so dass hier möglichst einfache Formen bevorzugt werden. Solche Getränkedosen bestehen heutzutage regelmäßig aus dünnem Aluminium oder Weißblech. In der Deckelfläche solcher Getränkedosen sind Öffnungsflächen vorgesehen, in denen ein vorgestanzter Bereich herausgebrochen werden kann, um eine Abgabeöffnung herzustellen. Eine derart geöffnete Getränkedose kann ohne zusätzliche Elemente nicht mehr dicht verschlossen werden.Especially in the case of beverage cans but also in other containers, which preferably contain liquids, resealable, well-sealed container closures can either not be attached or only with considerable effort. Of course, it is possible to provide a closable dispensing opening on the manufacturer side, in particular on plastic containers, whereby, however, the complexity of the injection molds used regularly increases and thus the production costs are higher. For mass products, such as the conventional metal beverage cans, the production costs are an essential criterion, so that the simplest possible forms are preferred here. Today, such beverage cans regularly consist of thin aluminum or tinplate. In the top surface of such beverage cans, there are provided opening surfaces in which a pre-punched region can be broken away to produce a dispensing opening. Such a opened beverage can can no longer be sealed tight without additional elements.

Beispielsweise die DE 40 35 395 A1 zeigt eine derartige Getränkedose, dort als Verpackungsmittel mit vorgefertigter Sollöffnung und dazugehörigem Lifthebel bezeichnet. In diesem Fall soll der Lifthebel als Wiederverschluss für die hergestellte Öffnung in der Getränkedose dienen. Dazu ist der Lifthebel schwenkbar gelagert und besitzt eine Verschlussfläche, die nach dem ersten Öffnen in die hergestellte Öffnung gedrückt werden kann. Eine sichere, flüssigkeitsdichte Verbindung lässt sich auf diese Weise jedoch kaum herstellen. Außerdem besteht das besondere Problem, dass die Materialkanten am Rande der hergestellten Öffnung dauerhaft von der in der Dose enthaltenen Flüssigkeit benetzt werden und aufgrund der an dieser Stelle fehlenden Oberflächenschutzschicht verstärkt zu Korrosion neigen.For example, the DE 40 35 395 A1 shows such a beverage can, there referred to as packaging means with prefabricated desired opening and associated lift lever. In this case, the lift lever should serve as a reclosure for the prepared opening in the beverage can. For this purpose, the lift lever is pivotally mounted and has a closure surface which can be pressed after the first opening in the prepared opening. A safe, liquid-tight connection can be made in this way, however, hardly. In addition, there is the particular problem that the edges of the material at the edge of the opening produced are permanently wetted by the liquid contained in the can and increasingly tend to corrosion due to the lack of surface protection layer at this point.

Die DE 295 11 368 U1 zeigt einen Getränkedosenverschluss, in Form eines auf die Dosenoberseite aufrastbaren Deckels mit einer verschließbaren Ausgießöffnung. Der Deckel besitzt einen zylinderförmigen Ansatz mit einer Abstufung. Die Ausgießöffnung ist durch einen schwenkbar gelagerten Deckelabschnitt verschließbar, der einen formschlüssig in die Ausgießöffnung eingreifenden Dichtkonus aufweist. Beim Gebrauch der Getränkedose kann allerdings Flüssigkeit zwischen der Dosenoberseite und dem separat aufgesetzten Deckel verbleiben. Es besteht außerdem die Gefahr, dass Flüssigkeit am Rand des aufrastbaren Deckels austritt. Außerdem ist der Getränkedosenverschluss nur aufwendig herzustellen. Auch bei dieser Anordnung bleiben die Öffnungsränder in der Öffnungsfläche der Getränkedose ungeschützt und neigen zu Korrosion.The DE 295 11 368 U1 shows a beverage can closure, in the form of a aufstastbaren on the top of the can lid with a closable pouring opening. The lid has a cylindrical approach with a gradation. The pouring opening can be closed by a pivotally mounted cover section, which has a sealing cone which engages in a form-fitting manner in the pouring opening. However, when using the beverage can, liquid may remain between the can top and the separately attached lid. There is also the risk that liquid leaks at the edge of the snap-on lid. In addition, the beverage can closure is expensive to produce. Even with this arrangement, the opening edges in the opening surface of the beverage can remain unprotected and prone to corrosion.

Die DE 20 2011 101 705 U1 beschreibt einen Verschluss für einen Flüssigkeitsbehälter, insbesondere für eine Getränkedose. Der Verschluss besitzt ein Verschlussunterteil zur flüssigkeitsdichten Montage in eine Öffnung in dem Flüssigkeitsbehälter, wobei das Verschlussunterteil einen Durchlass zum Ausgießen einer in dem Flüssigkeitsbehälter befindlichen Flüssigkeit aufweist. Weiterhin ist ein Verschlussoberteil vorgesehen, das auf dem Verschlussunterteil angeordnet ist und einen Durchlass für die Flüssigkeit aufweist. Das Verschlussoberteil ist relativ zum Verschlussunterteil drehbar, während das Verschlussunterteil in dem Flüssigkeitsbehälter fixiert ist. Schwierigkeiten bereitet auch in diesem Fall die Anbringung des Verschlussunterteils in der Öffnung der Öffnungsfläche. Insbesondere ist eine Abdichtung der Ränder der Öffnung nicht oder nur mit erheblichem Aufwand zu gewährleisten.The DE 20 2011 101 705 U1 describes a closure for a liquid container, in particular for a beverage can. The closure has a closure bottom for liquid-tight Mounting in an opening in the liquid container, wherein the closure lower part has a passage for pouring a liquid contained in the liquid container. Furthermore, an upper closure part is provided, which is arranged on the closure lower part and has a passage for the liquid. The closure top is rotatable relative to the closure bottom, while the closure bottom is fixed in the liquid container. Difficulties in this case, the attachment of the closure lower part in the opening of the opening surface. In particular, a seal of the edges of the opening is not or only with considerable effort to ensure.

Die US 2008/0110887 A1 beschreibt einen wieder verschließbaren Kunststoffverschluss für Metalldosen, der durch drei zueinander klappbare Ebenen gekennzeichnet ist. Eine Basisplatte adaptiert den Verschluss an einer Trinköffnung einer Getränkedose und weist eine Öffnung auf, die der Form nach der Trinköffnung an der Dose entspricht. Eine zweite, mit der Basisplatte mechanisch verbundene, mittlere Platte stellt ein Dichtelement dar, welches über die Basisplatte geklappt und in die Trinköffnung gedrückt werden kann, um diese teilweise zu schließen, gleichzeitig aber eine Durchflussöffnung offen zu lassen. Die Form des Dichtelements entspricht der Öffnung in der Basisplatte. Eine abschließende Ebene zeigt eine Abdeckung und ist mit der zweiten Dichtebene durch Scharniere mechanisch verbunden. Die abdeckende Ebene wird über das Dichtelement geklappt. Dabei werden zwei Öffnungen in der abdeckende Ebene auf zwei gegenüberliegende und zur Basisplatte gehörende Pins aufgerastet.The US 2008/0110887 A1 describes a resealable plastic closure for metal cans, which is characterized by three mutually hinged planes. A base plate adapts the closure to a drinking opening of a beverage can and has an opening which corresponds in shape to the drinking opening on the can. A second, mechanically connected to the base plate, middle plate is a sealing element which can be folded over the base plate and pressed into the drinking opening to close them partially, while leaving a flow opening open. The shape of the sealing element corresponds to the opening in the base plate. A final level shows a cover and is mechanically connected to the second sealing level by hinges. The covering plane is folded over the sealing element. In this case, two openings in the covering plane are snapped onto two opposite pins belonging to the base plate.

Die US 2012/0 273 490 A1 zeigt einen Dosendeckel aus Aluminium oder Kunststoff, als Bestandteil einer Getränkedose. Im ursprünglichen, geschlossenen Lieferzustand der Getränkedose ist diese durch eine Dichtung verschlossen, die durch Eindrücken durchbrochen werden kann. Der Dosendeckel weist zwei zueinander bewegliche Deckelteile auf, die zueinander geöffnet oder geschlossen werden können. Oberer und unterer Deckelteil besitzen eine Kreisform und sind übereinander drehbar gelagert. Beide Deckelteile weisen je eine Öffnung auf, die durch die Drehbewegung der Deckelteile übereinander positioniert werden können, um so eine Durchgangsöffnung zu schaffen. Beide Deckelteile sind an deren radialen Rändern formschlüssig durch einen Falz verbunden, die gleichzeitig eine Abdichtung bildet. Dabei sitzt der Rand des oberen Deckelteils unterhalb des Randes des unteren Deckelteils. Ein an einer Öffnung sitzendes Dichtelement zeigt eine radial umlaufende Dichtwulst mit einer Nut, die den Rand der Öffnung einschließt.The US 2012/0 273 490 A1 shows a can lid made of aluminum or plastic, as part of a beverage can. in the original, closed delivery state of the beverage can, this is closed by a seal that can be broken by impressions. The can lid has two mutually movable lid parts that can be opened or closed to each other. Upper and lower lid part have a circular shape and are rotatably mounted one above the other. Both cover parts each have an opening which can be positioned one above the other by the rotational movement of the cover parts, so as to create a passage opening. Both cover parts are positively connected at their radial edges by a fold, which simultaneously forms a seal. In this case, the edge of the upper lid part sits below the edge of the lower lid part. A seated at an opening sealing element shows a radially encircling sealing bead with a groove which encloses the edge of the opening.

Die DE 22 46 277 A1 zeigt einen Verschluss zum Verschließen einer in einer Stirnseite eines Behälters, insbesondere einer Getränkedose, angeordneten Auslauföffnung. Der Verschluss besteht aus zwei durch einen Verbindungssteg einstückig miteinander verbundenen Teilen, und zwar aus einem die Behälteröffnung verschließenden Verschlussteil und einem Klemmteil. Das Klemmteil ist nach dem Einstecken des Verschlussteiles in die Behälteröffnung in dieses einsteckbar. Es legt das Verschlussteil klemmend sowie abdichtend allseitig am Rand der Behälteröffnung fest.The DE 22 46 277 A1 shows a closure for closing a in an end face of a container, in particular a beverage can, arranged outlet opening. The closure consists of two parts integrally connected to one another by a connecting web, namely from a closure part closing the container opening and a clamping part. The clamping part can be inserted into the container opening after insertion of the closure part. It secures the closure part by clamping and sealing on all sides at the edge of the container opening.

Eine Aufgabe der vorliegenden Erfindung besteht ausgehend vom Stand der Technik darin, einen Behälterverschluss zur Verfügung zu stellen, der preiswert herstellbar ist, einfach in einer Öffnung eines Behälters, insbesondere einer Getränkedose angebracht werden kann, einen dichten Wiederverschluss ermöglicht und gleichzeitig die Schnittkanten der Öffnung dauerhaft vor einem Kontakt mit der im Behälter enthaltenen Flüssigkeit schützt, um eine Korrosion dieser Kanten zu verhindern.An object of the present invention, starting from the prior art, is to provide a container closure which is inexpensive to produce, can be easily mounted in an opening of a container, in particular a beverage can, a tight reclosure while simultaneously protecting the cut edges of the opening from contact with the liquid contained in the container to prevent corrosion of these edges.

Eine weitere Aufgabe wird darin gesehen, einen Behälter bereit zu stellen, der mit einem entsprechen verbesserten Behälterverschluss ausgerüstet ist.Another object is seen to provide a container which is equipped with a correspondingly improved container closure.

Diese Aufgaben werden durch einen Behälterverschluss gemäß dem beigefügten Anspruch 1 bzw. einen Behälter gemäß dem Anspruch 10 gelöst.These objects are achieved by a container closure according to the appended claim 1 and a container according to claim 10, respectively.

Der erfindungsgemäße Behälterverschluss besitzt an seinem aus Kunststoff bestehenden Flansch einen verformbaren Befestigungsabschnitt. Dieser umfasst eine radial außen liegende Dichtwulst mit in einer Querschnittsebene umlaufenden Nut. Die Breite der Nut entspricht im Wesentlichen der Dicke einer Öffnungsfläche eines zu verschließenden Behälters. Die Kontur der Nut entspricht im Wesentlichen der Kontur einer Öffnung in der Öffnungsfläche des Behälters. Der Befestigungsabschnitt des Behälterverschlusses umfasst weiterhin eine umlaufende Spreizfuge, die zwischen einem radial innen liegenden Wandabschnitt des Flansches und der radial außen liegenden Dichtwulst verläuft. Zum Behälterverschluss gehört darüber hinaus ein Deckel, der lösbar an einer Abgabeöffnung des Flansches angebracht ist. Dieser Deckel umfasst eine Verschlussfläche sowie eine sich an die Verschlussfläche anschließende Außenhülse. Der Querschnitt der Außenhülse ist derart an den Flansch angepasst, dass ein Aufsetzen des Deckels auf den Flansch zu einer flüssigkeitsdichten Verbindung führt. Die Außenhülse besitzt eine Längserstreckung, die ein Eindringen eines an ihrem freien Ende befindlichen Spreizelements in die Spreizfuge gestattet. Dabei ist das Spreizelement der Außenhülse derart gestaltet, dass die Dichtwulst bei diesem Eindringen radial nach außen gedrückt wird, um die Nut über den Rand der Öffnung des Behälters zu schieben. Dadurch wird einerseits der Flansch in der Öffnungsfläche des Behälters befestigt, andererseits ist die Kante der Öffnung in die Nut der Dichtwulst eingepresst und dauerhaft vor der Flüssigkeit geschützt, so dass eine Korrosion nicht mehr stattfinden kann.The container closure according to the invention has on its existing plastic flange a deformable mounting portion. This comprises a radially outer sealing bead with circumferential in a cross-sectional plane groove. The width of the groove substantially corresponds to the thickness of an opening area of a container to be closed. The contour of the groove substantially corresponds to the contour of an opening in the opening area of the container. The attachment portion of the container closure further comprises a circumferential expansion joint extending between a radially inner wall portion of the flange and the radially outer sealing bead. The container closure also includes a lid which is releasably attached to a discharge opening of the flange. This cover comprises a closure surface and an outer sleeve adjoining the closure surface. The cross section of the outer sleeve is adapted to the flange such that placing the cover on the flange results in a fluid-tight connection. The outer sleeve has a longitudinal extent, which is an ingress of a spreading element located at its free end in the Spreizfuge allowed. In this case, the expansion element of the outer sleeve is designed such that the sealing bead is pressed in this penetration radially outward to push the groove over the edge of the opening of the container. As a result, on the one hand the flange is fixed in the opening surface of the container, on the other hand, the edge of the opening is pressed into the groove of the sealing bead and permanently protected from the liquid, so that corrosion can no longer take place.

Bei besonderen Ausführungsformen des Behälterverschlusses beträgt die Tiefe der Nut zwischen 1 und 5 mm. Ebenfalls ist es vorteilhaft, wenn die Breite der Nut etwas geringer als die Materialstärke der Öffnungsfläche ist, vorzugsweise im Bereich zwischen 0,5 und 2,5 mm liegt. Das Material der Öffnungsfläche presst sich dann in das verformbare Material der Dichtwulst besonders gut ein. Die Nut kann eine sich nach innen verringernde Öffnungsbreite besitzen.In particular embodiments of the container closure, the depth of the groove is between 1 and 5 mm. It is also advantageous if the width of the groove is slightly less than the material thickness of the opening surface, preferably in the range between 0.5 and 2.5 mm. The material of the opening surface then presses into the deformable material of the sealing bead particularly well. The groove may have an inwardly decreasing opening width.

Vorteilhafte Ausführungsformen zeichnen sich durch eine sich verringernde Wandstärke am Ende der Außenhülse des Deckels aus. Insbesondere ist dieses freie Ende, welches das Spreizelement bildet, keilförmig gestaltet, um beim Eindringen in die Spreizfuge das Aufkeilen der Spreizfuge zu unterstützen.Advantageous embodiments are characterized by a decreasing wall thickness at the end of the outer sleeve of the lid. In particular, this free end, which forms the expansion element, designed wedge-shaped to support the wedging of the expansion joint when penetrating into the expansion joint.

Es ist vorteilhaft, wenn Flansch und Deckel einen kreisförmigen Querschnitt besitzen und an der Außenseite des Flansches sowie der Innenseite der Außenhülse des Deckels jeweils komplementäre Gewindeabschnitte angebracht sind. Der Deckel kann dann auf den Flansch aufgeschraubt werden, so dass auch geringe Kräfte ausreichend sind, um das freie Ende der Außenhülse des Deckels in die Spreizfuge eindringen zu lassen.It is advantageous if flange and cover have a circular cross-section and on the outside of the flange and the inside of the outer sleeve of the cover respectively complementary threaded portions are mounted. The lid can then be screwed onto the flange, so that even small forces are sufficient to allow the free end of the outer sleeve of the lid to penetrate into the expansion joint.

Eine bevorzugte Ausführungsform des Behälterverschlusses besitzt am Deckel Mitnehmerelemente, welche beim Einsetzen des Behälterverschlusses das Spreizelement zum Mitdrehen veranlassen. Ebenso kann über weitere Mitnehmer eine Drehung des Flansches bewirkt werden. Dies unterstützt wiederum das Eindringen der Ränder der Öffnung der Öffnungsfläche in die Nut der Dichtwulst.A preferred embodiment of the container closure has on the lid driver elements which cause the expansion element to co-rotate when inserting the container closure. Likewise, a rotation of the flange can be effected via further drivers. This in turn supports the penetration of the edges of the opening of the opening surface in the groove of the sealing bead.

Vorzugsweise besitzt der Befestigungsabschnitt des Flansches einen sich zum Flanschende hin verjüngenden Außendurchmesser. Diese Ausgestaltung erleichtert das Eindringen des Behälterverschlusses in die Öffnung der Getränkedose bzw. des sonstigen Behälters. Es ist dabei zweckmäßig, wenn das Flanschende beim Einsetzen in die Öffnung geringfügig in seinem Querschnitt verringert werden kann, im Rahmen einer elastischen Verformung, und nach dem Einsetzen in seine Ausgangsform zurückgeht, so dass die Nut bereits einen Teil des Randes der Öffnung aufnimmt und auf diese Weise den Behälterverschluss in axialer Richtung positioniert.Preferably, the attachment portion of the flange has an outer diameter tapering towards the flange end. This configuration facilitates the penetration of the container closure into the opening of the beverage can or other container. It is expedient if the flange can be slightly reduced in its cross-section during insertion into the opening, as part of an elastic deformation, and goes back to its original shape after insertion, so that the groove already receives part of the edge of the opening and on this way, the container closure positioned in the axial direction.

Erfindungsgemäß wird auch ein Flüssigkeitsbehälter, vorzugsweise in Form einer Getränkedose bereitgestellt, die eine Öffnung in einer Öffnungsfläche aufweist, wobei in der Öffnung ein erfindungsgemäßer Behälterverschluss eingesetzt ist. Der Behälterverschluss kann herstellerseitig eingesetzt werden, wenn die Getränkedose bereits mit diesem Verschluss verkauft werden soll. Ebenso ist es möglich, dem Nutzer einen separaten Behälterverschluss zur Verfügung zu stellen, den dieser dann nach dem ersten Öffnen der Getränkedose selbst einsetzen kann, sofern die Getränkedose wieder verschlossen werden soll.The invention also provides a liquid container, preferably in the form of a beverage can, which has an opening in an opening area, wherein a container closure according to the invention is inserted in the opening. The container closure can be used by the manufacturer, if the beverage can already be sold with this closure. It is also possible to provide the user with a separate container closure, which can then be used after the first opening of the beverage can itself, if the beverage can is to be closed again.

Es ist vorteilhaft, wenn die Getränkedose am Rand der Öffnung Vorsprünge aufweist, die in der Art einer Verrastung der dauerhaften Befestigung des Behälterverschlusses dienen.It is advantageous if the beverage can at the edge of the opening has projections which serve in the manner of locking the permanent attachment of the container closure.

Die Öffnung kann in der Getränkedose beispielsweise durch stanzen oder schneiden eingebracht werden.The opening can be introduced in the beverage can, for example by punching or cutting.

In Fig. 1 sind in einer Schnittansicht Abschnitte der wesentlichen Elemente des erfindungsgemäßen Behälterverschlusses dargestellt, bevor dieser in eine Öffnung einer Getränkedose eingesetzt wird. Der Behälterverschluss wird nachfolgend beispielhaft im Rahmen einer Verwendung an einer Getränkedose erläutert. Generell kann der Behälterverschluss aber auch an anderen Behältnissen verwendet werden.In Fig. 1 are shown in a sectional view sections of the essential elements of the container closure according to the invention before it is inserted into an opening of a beverage can. The container closure is exemplified below in use on a beverage can explained. In general, the container closure can also be used on other containers.

Der Behälterverschluss umfasst als einen ersten Hauptbestandteil einen Flansch 01, der vorzugsweise einstückig aus Kunststoff gefertigt ist. Der Flansch 01 besitzt vorzugsweise eine rohrförmige Gestalt mit einer zentralen Abgabeöffnung 02, durch welche die in einem Behälter 03 bevorratete Flüssigkeit abgegeben werden kann. Bei der dargestellten Ausführungsform handelt es sich bei dem Behälter 03 um eine Getränkedose, die an ihrer Oberseite eine Öffnungsfläche 04 besitzt. In der Öffnungsfläche 04 ist eine Öffnung 05 angebracht, in welche der Behälterverschluss einsetzbar ist.The container closure comprises as a first main component a flange 01, which is preferably made in one piece from plastic. The flange 01 preferably has a tubular shape with a central discharge opening 02, through which the liquid stored in a container 03 can be dispensed. In the illustrated embodiment, the container 03 is a beverage can having an opening area 04 at its top. In the opening area 04, an opening 05 is mounted, in which the container closure can be used.

Der Flansch 01 besitzt an seinem dem Behälter zugewandten Ende, also gegenüberliegend zur Abgabeöffnung 02, einen verformbaren Befestigungsabschnitt 06, der eine Dichtwulst 07 und eine umlaufende Spreizfuge 08 aufweist. Die Spreizfuge 08 verläuft zwischen einem radial innen liegenden Wandabschnitt des Flansches 01 und der radial außen liegenden Dichtwulst 07. Das Material des Flansches besitzt eine Elastizität, die ein Verschwenken der Dichtwulst 07 gestattet, wenn die Spreizfuge 08 aufgeweitet wird. In der Dichtwulst verläuft eine Nut 09 in einer Querschnittsebene, die senkrecht zur Längsachse des Flansches steht. Die Nut 09 ist nach außen geöffnet und in ihrer Breite an die Dicke der Öffnungsfläche 04 angepasst, um diese dichtend aufzunehmen.The flange 01 has at its end facing the container, so opposite to the discharge opening 02, a deformable mounting portion 06 which has a sealing bead 07 and a circumferential expansion joint 08. The Spreizfuge 08 extends between a radially inner wall portion of the flange 01 and the radially outer sealing bead 07. The material of the flange has an elasticity, which allows pivoting of the sealing bead 07 when the Spreizfuge 08 is widened. In the sealing bead extends a groove 09 in a cross-sectional plane which is perpendicular to the longitudinal axis of the flange. The groove 09 is open to the outside and adapted in width to the thickness of the opening surface 04 to receive these sealing.

Ein zweites Hauptteil des Behälterverschlusses wird durch einen Deckel 10 gebildet, der eine Verschlussfläche 11 und eine sich an diese anschließende Außenhülse 12 aufweist. Bei aufgesetztem Deckel 10 verschließt die Verschlussfläche 11 die Abgabeöffnung 02 des Flansches, damit dort keine Flüssigkeit austritt. Dafür können die an sich bekannten Formgestaltungen zur Schaffung einer dichten Verbindung verwendet werden, die hier nicht näher beschrieben werden. Die Außenhülse 12 umgreift den Flansch in axialer Erstreckung abschnittsweise und kann je nach Ausführungsform auf diesen aufgeschnappt oder aufgeschraubt werden. Am freien Ende der Außenhülse 12 ist ein Spreizelement 13 vorgesehen, welches beim Aufsetzen des Deckels in die Spreizfuge 08 eindringt, um die Dichtwulst radial nach außen zu verlagern. Die radiale Verlagerung ist durch die Elastizität des Materials ermöglicht, welche sowohl ein Verschwenken der Dichtwulst 07 als auch eine Dehnung des Materials am Fuß der Spreizfuge 08 gestattet. Das Spreizelement 13 kann einstückig mit der Außenhülse 12 gebildet sein oder als separates Teil. Ebenfalls ist es bei bestimmten Ausführungsformen möglich, dass das Spreizelement 13 zunächst an der Außenhülse 12 befestigt ist, nach dem Eindringen in die Spreizfuge jedoch von der Außenhülse gelöst wird und beim erneuten Entfernen des Deckels in der Spreizfuge verbleibt.A second main part of the container closure is formed by a cover 10 which has a closure surface 11 and an outer sleeve 12 adjoining thereto. When the lid 10 is mounted, the closure surface 11 closes the discharge opening 02 of the flange, so there is no liquid exit. For this purpose, the known shape designs can be used to create a tight connection, which will not be described in detail here. The outer sleeve 12 engages the flange in the axial extension sections and can be snapped or screwed depending on the embodiment of this. At the free end of the outer sleeve 12, an expansion element 13 is provided which penetrates when placing the cover in the expansion joint 08 in order to displace the sealing bead radially outward. The radial displacement is made possible by the elasticity of the material, which allows both a pivoting of the sealing bead 07 and an expansion of the material at the foot of the expansion joint 08. The expansion element 13 may be formed integrally with the outer sleeve 12 or as a separate part. It is also possible in certain embodiments, that the expansion element 13 is first attached to the outer sleeve 12, after the penetration of the expansion joint, however, is released from the outer sleeve and remains on renewed removal of the cover in the expansion joint.

Fig. 2 zeigt in einer Schnittansicht die Getränkedose 03 mit dem vollständig eingesetzten Behälterverschluss. Es ist ersichtlich, dass der untere Teil des Flansches 01 durch die Öffnung 05 in der Öffnungsfläche 04 hindurchgeführt wurde und der Rand der Öffnung 05 in die Nut 09 eingreift. Eine Schnittkante 15, welche die Kontur der Öffnung 05 bildet, ist damit vor angreifender Flüssigkeit geschützt, denn die Dichtwulst 07 umgreift das Material der Öffnungsfläche 04 vollständig, so dass die Schnittkante 15 abgedichtet in der Nut 09 liegt. Fig. 2 shows in a sectional view the beverage can 03 with the fully inserted container closure. It can be seen that the lower part of the flange 01 has been passed through the opening 05 in the opening surface 04 and the edge of the opening 05 engages in the groove 09. A cutting edge 15, which forms the contour of the opening 05, is thus protected from attacking liquid, because the sealing bead 07 completely surrounds the material of the opening surface 04, so that the cutting edge 15 is sealed in the groove 09.

Ebenso ist erkennbar, dass das Spreizelement 13 in die Spreizfuge 08 eingedrungen ist, wodurch die Dichtwulst 07 radial nach außen gedrückt wurde. Das Eindringen des Spreizelements 13 erfolgt beim Aufsetzen des Deckels 10 auf den Flansch 01, wobei in dem hier dargestellten Beispiel der Deckel 10 aufgeschraubt wird, unter Nutzung der Gewindeabschnitte 16 an der Außenseite des Flansches und an der Innenseite der Außenhülse 12.It can also be seen that the expansion element 13 has penetrated into the expansion joint 08, whereby the sealing bead 07 has been pressed radially outward. The penetration of the expansion element 13 takes place when placing the cover 10 on the flange 01, wherein in the example shown here, the cover 10 is screwed, using the threaded portions 16 on the outside of the flange and on the inside of the outer sleeve 12th

Fig. 3 zeigt eine Draufsicht auf die Öffnungsfläche 04 einer ersten Ausführungsform des Behälters 03. Es ist ersichtlich, dass die in der Öffnungsfläche 04 eingebrachte Öffnung 05 im Wesentlichen kreisrund ist und sich zentral in der Öffnungsfläche 04 befindet. Weiterhin ist erkennbar, dass die Kontur der Öffnung 05 mehrere, gleichmäßig am Umfang verteilte Vorsprünge 17 aufweist, die eine Verrastung des Flansches 01 in der Öffnungsfläche 04 zur Folge haben, wenn dieser erstmals eingesetzt wird und die Kontur der Öffnung 05 in die Nut 09 eingepresst wird, vorzugsweise unter gleichzeitigem Verdrehen des Flansches 01. Fig. 3 shows a plan view of the opening surface 04 of a first embodiment of the container 03. It can be seen that the introduced in the opening surface 04 opening 05 is substantially circular and is located centrally in the opening surface 04. Furthermore, it can be seen that the contour of the opening 05 has a plurality of evenly distributed on the circumference projections 17 which have a locking of the flange 01 in the opening surface 04 result when this is first used and the contour of the opening 05 is pressed into the groove 09 is, preferably with simultaneous rotation of the flange 01.

Fig. 4 zeigt eine zweite Ausführungsform des Behälters 03 in einer Draufsicht. Es ist erkennbar, dass die Vorsprünge 17 am Rand der Öffnung 05 in diesem Fall mit einer größeren radialen Erstreckung ausgebildet sind, so dass sich eine Art Sägezahnmuster ergibt. Fig. 4 shows a second embodiment of the container 03 in a plan view. It can be seen that the projections 17 are formed at the edge of the opening 05 in this case with a larger radial extent, so that there is a kind of sawtooth pattern.

Fig. 5 zeigt ein Detail des Behälterverschlusses. An der Außenhülse 12 des Deckels 10 sind Mitnehmerelemente 18 angebracht, die mit Anschlägen 19 am Spreizelement 13 zusammenwirken, um dieses beim ersten Verschließen des Behälterverschlusses mitzudrehen, wodurch das Eindringen des Spreizelementes 13 in die Spreizfuge 08 erleichtert wird. Wird beim nachfolgenden Öffnen des Behälterverschlusses der Deckel 10 in die entgegengesetzte Richtung gedreht, überspringen die Mitnehmerelemente 18 aufgrund vorhandener Auflaufschrägen an den Anschlägen 19 diese, so dass das Spreizelement 13 unverändert in der Spreizfuge 08 verbleibt. Fig. 5 shows a detail of the container closure. On the outer sleeve 12 of the cover 10 driving elements 18 are mounted, which cooperate with stops 19 on the spreader 13 to rotate this at the first closing of the container closure, whereby the penetration of the expansion element 13 is facilitated in the expansion joint 08. If, during the subsequent opening of the container closure, the cover 10 is rotated in the opposite direction, the driver elements 18 skip over the stops 19 due to existing run-on bevels, so that the expansion element 13 remains unchanged remains in the expansion joint 08.

Fig. 6 zeigt in einer vereinfachten perspektivischen Darstellung eine abgewandelte Ausführungsform des Behälterverschlusses. Auch in diesem Fall ist ein Deckel 10 sowie ein Flansch 01 vorgesehen, die gemeinsam den Behälterverschluss bilden. Abweichend von der zuvor beschriebenen Ausführungsform ist das Spreizelement 13 als separates Bauteil ausgebildet, welches beim Einsetzen des Behälterverschlusses in die Öffnung der Getränkedose über den Flansch gestülpt und nachfolgend vom Deckel in die Spreizfuge 08 gepresst wird und dort verbleibt. Fig. 6 shows a simplified perspective view of a modified embodiment of the container closure. Also in this case, a lid 10 and a flange 01 is provided, which together form the container closure. Notwithstanding the embodiment described above, the expansion element 13 is formed as a separate component, which is placed over the flange during insertion of the container closure into the opening of the beverage can and subsequently pressed by the cover into the expansion joint 08 and remains there.
