Definitions

  • the invention relates to the lid of a container, in particular a beverage can, with an essentially flat lid mirror and a preferably folded edge area, at least one reclosable pouring opening being arranged on the lid mirror, with an essentially one-piece closure means belonging to the pouring opening, which is completely on the underside of the lid mirror is attached in a rotationally fixed manner and with an actuating means which is connected to the closure means and penetrates the lid mirror and which is arranged on the top side of the lid mirror and is accessible from the outside, the closure means being adjustable from a closed position by actuating the actuating means to an open position, and wherein the actuating means has a holding element which cooperates with the cover mirror when the closure means is in the open position.
  • Another group of closure means for beverage cans consists of a tear-open tab which is fastened to the can lid, for example by means of a rivet connection, the handle part of the tear-open tab being simultaneously designed as a closure means for the pouring opening, which after opening the pouring opening by twisting and / or flipping the Tear tab closes the pouring opening again.
  • Such elements are among others in the DE 197 46 539 A1 , of the DE 203 19 105 U1 , of the EP 1 190 952 A2 , of the EP 1 097 086 B1 and the EP 0 433 502 A1 shown.
  • These beverage cans all have a closure which is applied to the pouring opening from the outside and in some cases protrudes beyond the edge of the lid, so that it can be removed unintentionally and the contents of the can are thus exposed to the environment.
  • the GB 2 331 284 A finally describes a closure system consisting of a tear-open tab for exposing a pouring opening and a closure means which is arranged on the underside of the can lid inside the can, a spring element pressing the closure means against the pouring opening.
  • This closure means has the disadvantage that it has an extremely complicated structure and requires a change to the usual can lid.
  • the closure device can also be of a somewhat simpler construction, also multi-part US 3,889,842 are removed, which also requires an elaborately modified lid. In the US 4,746,032 A similar reusable closure means are described.
  • the US 5,812,189 A describes a lid of the type mentioned with an additional closure means, which is arranged inside the beverage can and is pressed by spring force against the drinking opening.
  • This closure system is also a hindrance, particularly when the container lid is being mounted on the beverage can during the filling process.
  • a cover according to claim 1 solved in that the closure means can be moved from the closed position substantially perpendicular to the lid mirror into the open position and that the actuating means covers the pouring opening in the closed position.
  • the actuating means covers the pouring opening in the closed position. This prevents, for example, when the reclosed beverage can is transported in a pocket, further objects in the pocket can move the closure means from its closed position into an at least partially open position, and thus the contents of the can pour into the pocket.
  • the closure means has a fastening part which is in a non-detachable connection to the lid mirror, and a closure region which closes the pouring opening in a liquid-tight manner, wherein a joint is provided between the fastening part and the closure region, about which the closure region of the closure means can be pivoted against a restoring force, and the joint is designed as an area with increased flexibility between the fastening part and the closure region.
  • this joint is designed as an area with a smaller material cross section located between the fastening part and the closure area. If the closure means is made of an elastic material, the closure means is folded away when the actuating means is actuated, a force corresponding to the elastic properties of the material of the closure means having to be applied for this.
  • the preferably one-piece closure means By attaching the preferably one-piece closure means in a torsion-proof manner, for example by gluing or soldering to the underside of the cover mirror, rapid assembly of the closure means on a commercially available cover is possible, with no or only slight change of the cover, for example a simple punching out for the Carrying out the actuating means through the cover are necessary.
  • the edge region of the lid remains unchanged, so that the lid can be placed and fastened on the container, in particular on the beverage can, in the usual way.
  • the actuating means can be rotated essentially in one plane parallel to the cover mirror. Alternatively, it can be moved. The movement of the actuating means on the one hand removes the closure means from the pouring opening, preferably moving it essentially vertically out of the closed position, in particular by folding it away into the interior of the can, on the other hand the actuating means itself releases the pouring opening.
  • closure means is designed as a two-component injection molded part.
  • the actuating means connected to the closure means - it can also be formed, for example, in one piece with the closure means - causes the closure means to be folded out of the plane of the pouring opening into the interior of the can, that is to say can be moved into the open position essentially perpendicular to the can level. this releases the pouring opening and thus the contents of the can can be removed.
  • the holding element of the actuating means is advantageously designed as a detent for receiving at least one edge of the cover mirror when the closure means is open.
  • the closure means is fixed in the open position and the contents of the can can be removed without having to exert any additional force on the actuating means.
  • the locking means can be held in the open position by a latching hinge.
  • the actuating means can be designed differently. In a preferred embodiment, it is wedge-shaped.
  • the wedge surface can be straight or helically curved.
  • the actuating means is arranged on the surface of the lid mirror so as to be rotatable essentially about its central axis running perpendicular to the lid mirror, wherein it acts on the closing means when it is turned, so that the closing area is pivoted into the open position.
  • the actuating means is designed as a lever with a latching lug that projects substantially perpendicularly from the cover mirror.
  • An improved sealing of the pouring opening by the closing means is given if an additional sealing means is arranged between the closing area of the closing means and the lid mirror.
  • This can be arranged, for example, on the side of the closure means facing the pouring opening. It can also be attached to the underside of the can mirror, advantageously enclosing the edges of the pouring opening in order to prevent injuries, for example when drinking from the can.
  • the sealant simultaneously forms the area made of elastic material, so that this reduces the number of individual parts of the lid and thus, according to the invention, a higher stability of the closure of the pouring opening of a beverage can is achieved.
  • Packaging security is an important aspect, particularly with food packaging.
  • the pouring opening is preferably sealed with a seal before the first opening.
  • this seal is, for example, a badge or a label which has to cover and remove the pouring opening before the can contents can be removed.
  • the seal is designed as a pre-punched closure flap which is pulled off when the container is opened for the first time and thereby releases the pouring opening in the lid mirror.
  • the pouring opening is closed with the closure means before the first opening, the actuating means having a securing device.
  • the actuating means can be provided with a label which at least partially covers the lid mirror, so that the label tears when the actuating means is actuated and thus indicates manipulation of the container.
  • securing device which has a predetermined breaking point which is broken open when the container is opened for the first time. If, for example, a label is used as a securing means, it can under certain circumstances be removed entirely and put back on the container without a glance at a difference from an untouched label being recognizable. A manipulation of the contents of the container would not be recognizable at first glance. In the case of a securing device with a predetermined breaking point, however, manipulation of the seal cannot be made unnoticeable again and is therefore particularly safe for the end user.

Es sind zahlreiche Getränkedosen bekannt geworden, die über eine wiederverschließbare Ausgießöffnung verfügen. So offenbart beispielsweise die DE 196 13 246 A1 ein auf den bereits bestehenden Deckel aufgebrachtes Verschlussmittel mit im Wesentlichen gleichem Durchmesser, das durch Verdrehen eine im Deckel befindliche Ausgießöffnung verschließt. Ähnliche Vorrichtungen, wobei einige dieser Verschlussmittel nur teilweise den Deckel bedecken, sind der DE 196 13 256 B4 , der DE 197 06 112 C2 , der EP 1 247 752 B1 oder der US 6,626,314 B1 beschrieben. Nachteilig an diesen Verschlüssen ist ihr zumeist komplizierter Aufbau, der zudem konstruktive Veränderungen des Deckelbereiches der Dose verlangt. Wiederverschließbare Dosen sind auch in US 6,626,314 B1 und DE 203 19 105 U1 offenbart.Numerous beverage cans have become known which have a reclosable pouring opening. For example, the DE 196 13 246 A1 a closure means applied to the already existing lid with essentially the same diameter, which closes a pouring opening in the lid by twisting. Similar devices, with some of these closure means only partially covering the lid, are DE 196 13 256 B4 , of the DE 197 06 112 C2 , of the EP 1 247 752 B1 or the US 6,626,314 B1 described. A disadvantage of these closures is their mostly complicated structure, which also requires structural changes to the lid area of the can. Resealable cans are also in US 6,626,314 B1 and DE 203 19 105 U1 disclosed.

Eine weitere Gruppe von Verschlussmittel für Getränkedosen besteht aus einer Aufreißlasche, die beispielsweise mittels einer Nietverbindung an dem Dosendeckel befestigt ist, wobei der Griffteil der Aufreißlasche gleichzeitig als Verschlussmittel für die Ausgießöffnung ausgebildet ist, das nach dem Öffnen der Ausgießöffnung durch Verdrehen und/oder Umklappen der Aufreißlasche die Ausgießöffnung wieder verschließt. Derartige Elemente sind unter anderem in der DE 197 46 539 A1 , der DE 203 19 105 U1 , der EP 1 190 952 A2 , der EP 1 097 086 B1 und der EP 0 433 502 A1 gezeigt. Diese Getränkedosen weisen allesamt einen Verschluss auf, der von außen auf die Ausgießöffnung aufgebracht wird und dabei zum Teil über den Deckelrand hinausragt, so dass dieser unbeabsichtigterweise entfernt werden kann und damit der Doseninhalt der Umgebung ausgesetzt wird.Another group of closure means for beverage cans consists of a tear-open tab which is fastened to the can lid, for example by means of a rivet connection, the handle part of the tear-open tab being simultaneously designed as a closure means for the pouring opening, which after opening the pouring opening by twisting and / or flipping the Tear tab closes the pouring opening again. Such elements are among others in the DE 197 46 539 A1 , of the DE 203 19 105 U1 , of the EP 1 190 952 A2 , of the EP 1 097 086 B1 and the EP 0 433 502 A1 shown. These beverage cans all have a closure which is applied to the pouring opening from the outside and in some cases protrudes beyond the edge of the lid, so that it can be removed unintentionally and the contents of the can are thus exposed to the environment.

Die GB 2 331 284 A schließlich beschreibt ein Verschlusssystem, bestehend aus einer Aufreißlasche zum Freilegen einer Ausgießöffnung, sowie einem Verschlussmittel, das an der Unterseite des Dosendeckels im Inneren der Dose angeordnet ist, wobei ein Federelement das Verschlussmittel gegen die Ausgießöffnung presst. Um die Dose entleeren zu können, müssen Teile des Verschlussmittels gegen die Aufreißlasche verschoben werden. Dieses Verschlussmittel hat den Nachteil, dass es äußerst kompliziert aufgebaut ist und eine Veränderung der üblichen Dosendeckel erfordert. Eine im Aufbau etwas einfacher gehaltenere, ebenfalls mehrteilige Verschlusseinrichtung kann der US 3,889,842 entnommen werden, die ebenfalls einen aufwendig veränderten Deckel benötigt. In der US 4,746,032 A sind ähnliche wiederverwendbare Verschlussmittel beschrieben.The GB 2 331 284 A finally describes a closure system consisting of a tear-open tab for exposing a pouring opening and a closure means which is arranged on the underside of the can lid inside the can, a spring element pressing the closure means against the pouring opening. In order to be able to empty the can, parts of the closure must be pushed against the tear tab. This closure means has the disadvantage that it has an extremely complicated structure and requires a change to the usual can lid. The closure device can also be of a somewhat simpler construction, also multi-part US 3,889,842 are removed, which also requires an elaborately modified lid. In the US 4,746,032 A similar reusable closure means are described.

Die US 5,812,189 A beschreibt einen Deckel der eingangs erwähnten Art mit einem zusätzlichen Verschlussmittel, das im Inneren der Getränkedose angeordnet ist und mittels Federkraft gegen die Trinköffnung gepresst wird. Auch dieses Verschlusssystem ist insbesondere bei der Montage der Behälterdeckel auf die Getränkedose während des Befüllvorgangs hinderlich.The US 5,812,189 A describes a lid of the type mentioned with an additional closure means, which is arranged inside the beverage can and is pressed by spring force against the drinking opening. This closure system is also a hindrance, particularly when the container lid is being mounted on the beverage can during the filling process.

Es ist daher Aufgabe der Erfindung die oben beschriebenen Nachteile des Standes der Technik zu beseitigen und einen Deckel für eine Dose bereitzustellen, der über ein sicheres Verschlusssystem zum Wiederverschließen der Dose verfügt, das bevorzugterweise auf einfache und kostengünstige Weise in handelsübliche Deckel montiert werden kann.It is therefore an object of the invention to eliminate the disadvantages of the prior art described above and to provide a lid for a can, which has a secure closure system for reclosing the can, which can preferably be mounted in a commercially available lid in a simple and inexpensive manner.

Diese Aufgabe wird erfindungsgemäß durch einen Deckel gemäß Anspruch 1
dadurch gelöst, dass das Verschlussmittel aus der Schließstellung im Wesentlichen senkrecht zum Deckelspiegel in die Offenstellung bewegbar ist und dass das Betätigungsmittel in der Schließstellung die Ausgießöffnung abdeckt. Um nach dem erstmaligen Öffnen der Getränkedose diese sicher transportieren zu können, ohne beispielsweise durch ungewolltes Eindrücken des Verschlussmittels den verbleibenden Inhalt der Getränkedose freizugeben, deckt in einer weiteren bevorzugten Ausführung der Erfindung das Betätigungsmittel die Ausgießöffnung in der Schließstellung ab. Damit wird verhindert, dass beispielsweise bei Transportieren der wiederverschlossenen Getränkedose in einer Tasche weitere in der Tasche befindliche Gegenstände das Verschlussmittel aus seiner Schließposition in eine zumindest teilweise geöffnete Position bewegen können und sich damit der Doseninhalt in die Tasche ergießt.This object is achieved according to the invention by a cover according to claim 1
solved in that the closure means can be moved from the closed position substantially perpendicular to the lid mirror into the open position and that the actuating means covers the pouring opening in the closed position. In order to be able to transport the beverage can safely after opening it for the first time without, for example, unintentionally pressing in the closure means to release the remaining contents of the beverage can, in a further preferred embodiment of the invention the actuating means covers the pouring opening in the closed position. This prevents, for example, when the reclosed beverage can is transported in a pocket, further objects in the pocket can move the closure means from its closed position into an at least partially open position, and thus the contents of the can pour into the pocket.

Erfindungsgemäß weist das Verschlussmittel einen Befestigungsteil auf, der mit dem Deckelspiegel in unlösbarer Verbindung steht, sowie einen Verschlussbereich, der die Ausgießöffnung flüssigkeitsdicht verschließt, wobei zwischen Befestigungsteil und Verschlussbereich ein Gelenk vorgesehen ist, um die der Verschlussbereich des Verschlussmittels gegen eine Rückstellkraft verschwenkbar ist, und das Gelenk als ein zwischen Befestigungsteil und Verschlussbereich befindlicher Bereich mit erhöhter Flexibilität ausgebildet ist. Dieses Gelenk ist in einer besonders einfachen und kostengünstigen Ausführung der Erfindung als ein zwischen Befestigungsteil und Verschlussbereich befindlicher Bereich mit geringerem Materialquerschnitt ausgebildet. Ist das Verschlussmittel aus einem elastischen Material gefertigt, so wird bei Betätigung des Betätigungsmittels das Verschlussmittel weggeklappt, wobei hierfür eine den elastischen Eigenschaften des Materials des Verschlussmittels entsprechende Kraft aufgebracht werden muss.According to the invention, the closure means has a fastening part which is in a non-detachable connection to the lid mirror, and a closure region which closes the pouring opening in a liquid-tight manner, wherein a joint is provided between the fastening part and the closure region, about which the closure region of the closure means can be pivoted against a restoring force, and the joint is designed as an area with increased flexibility between the fastening part and the closure region. In a particularly simple and inexpensive embodiment of the invention, this joint is designed as an area with a smaller material cross section located between the fastening part and the closure area. If the closure means is made of an elastic material, the closure means is folded away when the actuating means is actuated, a force corresponding to the elastic properties of the material of the closure means having to be applied for this.

Durch die Anbringung des vorzugsweisen einstückigen Verschlussmittels auf verdrehfeste Weise, beispielsweise durch Ankleben oder Anlöten an der Unterseite des Deckelspiegels, ist eine rasche Montage des Verschlussmittels auf einem handelsüblichen Deckel möglich, wobei gar keine oder nur geringfügige Veränderung des Deckels, beispielsweise eine einfache Ausstanzung für die Durchführung des Betätigungsmittels durch den Deckel, notwendig sind. Insbesondere der Randbereich des Deckels bleibt unverändert, so dass ein Aufsetzen und Befestigen des Deckels auf dem Behälter, insbesondere auf der Getränkedose, auf die übliche Weise erfolgen kann.By attaching the preferably one-piece closure means in a torsion-proof manner, for example by gluing or soldering to the underside of the cover mirror, rapid assembly of the closure means on a commercially available cover is possible, with no or only slight change of the cover, for example a simple punching out for the Carrying out the actuating means through the cover are necessary. In particular, the edge region of the lid remains unchanged, so that the lid can be placed and fastened on the container, in particular on the beverage can, in the usual way.

In einer bevorzugten Ausführung der Erfindung ist das Betätigungsmittel im Wesentlichen in einer Ebene parallel zu dem Deckelspiegel verdrehbar. Alternativ hierzu ist es verschiebbar. Durch die Bewegung des Betätigungsmittels wird einerseits das Verschlussmittel von der Ausgießöffnung entfernt, wobei es bevorzugt im Wesentlichen senkrecht aus der Schließstellung, insbesondere durch Wegklappen in das Doseninnere bewegt wird, andererseits gibt das Betätigungsmittel selbst die Ausgießöffnung frei.In a preferred embodiment of the invention, the actuating means can be rotated essentially in one plane parallel to the cover mirror. Alternatively, it can be moved. The movement of the actuating means on the one hand removes the closure means from the pouring opening, preferably moving it essentially vertically out of the closed position, in particular by folding it away into the interior of the can, on the other hand the actuating means itself releases the pouring opening.

Besonders einfach in der Herstellung und damit kostengünstig ist es, wenn das Verschlussmittel als Zweikomponenten-Spritzgussteil ausgeführt ist.It is particularly easy to manufacture and therefore inexpensive if the closure means is designed as a two-component injection molded part.

Das mit dem Verschlussmittel in Verbindung stehende Betätigungsmittel - es kann beispielsweise ebenfalls einstückig mit dem Verschlussmittel ausgebildet sein - bewirkt bei Betätigung, dass das Verschlussmittel aus der Ebene der Ausgießöffnung in das Doseninnere weggeklappt wird, also im Wesentlichen senkrecht zum Dosenspiegel in die Offenstellung bewegbar ist, dadurch die Ausgießöffnung freigegeben und somit der Doseninhalt entnehmbar wird.When actuated, the actuating means connected to the closure means - it can also be formed, for example, in one piece with the closure means - causes the closure means to be folded out of the plane of the pouring opening into the interior of the can, that is to say can be moved into the open position essentially perpendicular to the can level. this releases the pouring opening and thus the contents of the can can be removed.

Um beim Entleeren der Dose nicht eine ständige Krafteinwirkung auf das Verschlussmittel zu benötigen, ist vorteilhafterweise das Halteelement des Betätigungsmittels als Rastnase für die Aufnahme von zumindest einer Kante des Deckelspiegels bei Offenstellung des Verschlussmittels ausgebildet. Dadurch wird das Verschlussmittel in der Offenstellung fixiert und der Doseninhalt kann entnommen werden, ohne dass eine zusätzliche Kraft auf das Betätigungsmittel ausgeübt werden muss. Alternativ dazu kann das Verschlussmittel durch ein einrastendes Scharnier in der geöffneten Stellung gehalten werden.In order not to require constant force on the closing means when emptying the can, the holding element of the actuating means is advantageously designed as a detent for receiving at least one edge of the cover mirror when the closure means is open. As a result, the closure means is fixed in the open position and the contents of the can can be removed without having to exert any additional force on the actuating means. Alternatively, the locking means can be held in the open position by a latching hinge.

Das Betätigungsmittel kann unterschiedlich ausgebildet sein. So ist es in einer bevorzugten Ausführung keilförmig. Die Keilfläche kann dabei geradlinig oder aber schraubenförmig gekrümmt ausgebildet sein.The actuating means can be designed differently. In a preferred embodiment, it is wedge-shaped. The wedge surface can be straight or helically curved.

In einer anderen Ausführung der Erfindung ist das Betätigungsmittel im Wesentlichen um seine senkrecht zum Deckelspiegel verlaufende Mittelachse verdrehbar auf der Oberfläche des Deckelspiegels angeordnet, wobei es bei Verdrehen auf das Verschlussmittel einwirkt, so dass der Verschlussbereich in die Offenstellung verschwenkt wird.In another embodiment of the invention, the actuating means is arranged on the surface of the lid mirror so as to be rotatable essentially about its central axis running perpendicular to the lid mirror, wherein it acts on the closing means when it is turned, so that the closing area is pivoted into the open position.

In einer weiteren Variante der Erfindung ist das Betätigungsmittel als ein im Wesentlichen senkrecht von dem Deckelspiegel aufragender Hebel mit einer Rastnase ausgebildet.In a further variant of the invention, the actuating means is designed as a lever with a latching lug that projects substantially perpendicularly from the cover mirror.

Eine verbesserte Abdichtung der Ausgießöffnung durch das Verschlussmittel ist gegeben, wenn zwischen dem Verschlussbereich des Verschlussmittels und dem Deckelspiegel ein zusätzliches Dichtmittel angeordnet ist. Dieses kann beispielsweise auf der der Ausgießöffnung zugewandten Seite des Verschlussmittels angeordnet sein. Ebenso kann es an der Unterseite des Dosenspiegel angebracht sein, wobei es vorteilhafterweise die Kanten der Ausgießöffnung umschließt, um Verletzungen beispielsweise beim Trinken aus der Dose zu verhindern.An improved sealing of the pouring opening by the closing means is given if an additional sealing means is arranged between the closing area of the closing means and the lid mirror. This can be arranged, for example, on the side of the closure means facing the pouring opening. It can also be attached to the underside of the can mirror, advantageously enclosing the edges of the pouring opening in order to prevent injuries, for example when drinking from the can.

Bevorzugterweise bildet das Dichtmittel gleichzeitig den Bereich aus elastischem Material aus, so dass dadurch die Anzahl an Einzelteilen des Deckels reduziert und damit erfindungsgemäß eine höhere Stabilität des Verschlusses der Ausgießöffnung einer Getränkedose erzielt wird.Preferably, the sealant simultaneously forms the area made of elastic material, so that this reduces the number of individual parts of the lid and thus, according to the invention, a higher stability of the closure of the pouring opening of a beverage can is achieved.

Ein wesentlicher Aspekt insbesondere bei Lebensmittelverpackungen ist die Verpackungssicherheit. Darunter wird im Rahmen dieser Offenbarung jener Schutz verstanden, bei welchem der Inhalt der Lebensmittelverpackung, im vorliegenden Fall der Inhalt der Getränkedose, bis zum Öffnen durch den Endverbraucher vor Manipulation oder Entnahme geschützt wird. So ist bevorzugterweise die Ausgießöffnung vor dem ersten Öffnen mit einer Versiegelung verschlossen. Diese Versiegelung ist im einfachsten Fall beispielsweise eine Plakette oder ein Etikett, das die Ausgießöffnung verdeckt und entfernt werden muss, bevor der Doseninhalt entnommen werden kann.Packaging security is an important aspect, particularly with food packaging. In the context of this disclosure, this means protection in which the contents of the food packaging, in the present case the contents of the beverage can, are protected from manipulation or removal until the end user opens them. For example, the pouring opening is preferably sealed with a seal before the first opening. In the simplest case, this seal is, for example, a badge or a label which has to cover and remove the pouring opening before the can contents can be removed.

In einer anderen Ausführung der Erfindung ist die Versiegelung als eine vorgestanzte Verschlusslasche ausgebildet ist, die beim ersten Öffnen des Behälters abgezogen wird und dabei die Ausgießöffnung im Deckelspiegel freigibt.In another embodiment of the invention, the seal is designed as a pre-punched closure flap which is pulled off when the container is opened for the first time and thereby releases the pouring opening in the lid mirror.

In einer weiteren Variante ist die Ausgießöffnung vor dem ersten Öffnen mit dem Verschlussmittel verschlossen, wobei das Betätigungsmittel eine Sicherungseinrichtung aufweist. So kann beispielsweise das Betätigungsmittel mit einem Etikett versehen sein, das zumindest teilweise den Deckelspiegel bedeckt, so dass das Etikett bei Betätigung des Betätigungsmittels reißt und damit eine Manipulation des Behälters anzeigt.In a further variant, the pouring opening is closed with the closure means before the first opening, the actuating means having a securing device. For example, the actuating means can be provided with a label which at least partially covers the lid mirror, so that the label tears when the actuating means is actuated and thus indicates manipulation of the container.

Besonders bevorzugt ist jene Sicherungseinrichtung, die über eine Sollbruchstelle verfügt, die beim erstmaligen Öffnen des Behälters aufgebrochen wird. Bei der Verwendung beispielsweise eines Etiketts als Sicherungsmittel kann dieses unter Umständen zur Gänze entfernt und wieder auf den Behälter aufgebracht werden, ohne dass bei flüchtigem Hinsehen ein Unterschied zu einem unberührten Etikett erkennbar ist. Eine Manipulation des Behälterinhaltes wäre somit auf dem ersten Blick nicht erkennbar. Bei einer Sicherungseinrichtung mit einer Sollbruchstelle hingegen kann eine Manipulation der Versiegelung nicht wieder unbemerkbar gemacht werden und ist daher besonders sicher für den Endverbraucher.Particularly preferred is that securing device which has a predetermined breaking point which is broken open when the container is opened for the first time. If, for example, a label is used as a securing means, it can under certain circumstances be removed entirely and put back on the container without a glance at a difference from an untouched label being recognizable. A manipulation of the contents of the container would not be recognizable at first glance. In the case of a securing device with a predetermined breaking point, however, manipulation of the seal cannot be made unnoticeable again and is therefore particularly safe for the end user.

Bei einer weiteren Ausführung der Erfindung ist zusätzlich zur Ausgießöffnung eine Belüftungseinrichtung vorgesehen, die gemeinsam mit der Ausgießöffnung durch das Verschlussmittel verschließbar ist. Diese Belüftungseinrichtung erlaubt eine besonders einfache Entleerung des Doseninhalts ohne Unterbrechung aufgrund von Unterdruck in der Getränkedose.In a further embodiment of the invention, in addition to the pouring opening, a ventilation device is provided which can be closed by the closure means together with the pouring opening. This ventilation device allows a particularly simple emptying of the can contents without interruption due to negative pressure in the beverage can.

Besonders kostengünstig ist es, wenn das Verschlussmittel und/oder das Betätigungsmittel aus Kunststoff gefertigt sind. Selbstverständlich muss im Falle von Lebensmittelverpackungen das eingesetzte Material lebensmitteltauglich sein.It is particularly cost-effective if the closure means and / or the actuating means are made of plastic. Of course, in the case of food packaging, the material used must be suitable for food.

Wie in Fig. 1 dargestellt, ist das Verschlussmittel
eine im Wesentlichen ebene Platte, die durch eine Ausbuchtung 2 in zwei Bereiche unterteilt ist. Diese Ausbuchtung stellt im wesentlichen ein Gelenk 2 dar, das über einen elastischen Bereich 21 verfügt, wobei das Verschlussmittel 1 insbesondere als Zweikomponenten-Spritzgussteil gefertigt ist. Der Bereich mit der geringeren Fläche ist der Befestigungsteil 3 des Verschlussmittels 1, der zur verdrehfesten Befestigung des Verschlussmittels 1 an der Deckelunterseite eines Behälters dient. Auf dem Bereich mit der größeren Ausdehnung, dem Verschlussbereich 4, befindet sich ein im Querschnitt T-förmiger Aufsatz 5, der einstückig mit dem Verschlussmittel 1 gefertigt ist. Das Verschlussmittel 1 ist in der dargestellten Ausführung aus einem biegeelastischen Material, beispielsweise Kunststoff gefertigt.As in Fig. 1 shown is the closure means
a substantially flat plate, which is divided into two areas by a bulge 2. This bulge essentially represents a joint 2 which has an elastic region 21, the closure means 1 being manufactured in particular as a two-component injection molded part. The area with the smaller area is the fastening part 3 of the closure means 1, which serves for the rotationally fixed fastening of the closure means 1 on the underside of the lid of a container. On the area with the greater extent, the closure area 4, there is an attachment 5 with a T-shaped cross section, which is made in one piece with the closure means 1. In the embodiment shown, the closure means 1 is made of a flexible material, for example plastic.

Auf diesen Aufsatz 5 kann ein Betätigungsmittel 6, das beispielsweise gemäß Fig. 2 keilförmig ausgebildet, befestigt werden. Hierfür besitzt das Betätigungsmittel 6 eine Ausnehmung 7, deren Querschnitt im Wesentlichen jenem des Aufsatzes 5 entspricht. Fig. 3 zeigt das Verschlussmittel 1 mit aufgesetztem Betätigungsmittel 6.An actuating means 6, which for example according to FIG Fig. 2 be wedge-shaped, attached. For this purpose, the actuating means 6 has a recess 7, the cross section of which essentially corresponds to that of the attachment 5. Fig. 3 shows the closure means 1 with the actuating means 6 attached.

Das Verschlussmittel 1 wird an der Unterseite eines Behälterdeckels 8, insbesondere an der Unterseite des Deckelspiegels 9 einer Getränkedose befestigt. Dabei verschließt der Verschlussbereich 4 eine exzentrisch auf dem Deckelspiegel 9 angeordnete Ausgießöffnung 10. Durch eine im Mittelbereich des Deckelspiegels 9 befindliche Ausnehmung 11 ragt der T-förmige Aufsatz 5 hindurch, auf dem das keilförmige Betätigungsmittel 6 aufgesetzt ist. Zur Freigabe der Ausgießöffnung 10 durch Verschwenken des Verschlussbereichs 4 des Verschlussmittels 1 aus der Ebene des Deckelspiegels 9 wird das Betätigungsmittel 6 in Pfeilrichtung gemäß Fig. 4 derart bewegt, dass die beiden Schenkel 12, 12' zwischen Deckelspiegel 9 und Verschlussmittel 1 gleiten. Der elastische Bereich 21 dient hierbei als Gelenk 2, das die Schwenkachse des Verschlussbereichs 4 bildet. Dabei wird gleichzeitig das keilförmige Betätigungsmittel 6 über den Aufsatz 5 bewegt, der in die Aufnahme 7 des Betätigungsmittels 6 eingreift.The closure means 1 is attached to the underside of a container lid 8, in particular to the underside of the lid mirror 9 of a beverage can. In this case, the closure area 4 closes a pouring opening 10 arranged eccentrically on the lid mirror 9. The T-shaped attachment 5, on which the wedge-shaped actuating means 6 is placed, projects through a recess 11 in the middle area of the lid mirror 9. For Release of the pouring opening 10 by pivoting the closure area 4 of the closure means 1 from the plane of the cover mirror 9, the actuating means 6 in the direction of the arrow Fig. 4 moved in such a way that the two legs 12, 12 'slide between the cover mirror 9 and the closure means 1. The elastic region 21 serves here as a joint 2, which forms the pivot axis of the closure region 4. At the same time, the wedge-shaped actuating means 6 is moved over the attachment 5, which engages in the receptacle 7 of the actuating means 6.

Aufgrund des zunehmenden Querschnitts der beiden Schenkel 12, 12' vergrößert sich der Abstand zwischen Deckelspiegel 9 und Verschlussmittel 1, wobei der Verschlussbereich 4 um eine im Wesentlichen in der Ausbuchtung 2 liegende Schwenkachse verschwenkt wird. Die in dem Verschlussmittel 1 befindliche Ausbuchtung 2 fungiert somit als Gelenk, um deren Achse der Verschlussbereich 4 aus der Ebene des Deckelspiegels 9 verschwenkt wird.Due to the increasing cross-section of the two legs 12, 12 ', the distance between the cover mirror 9 and the closure means 1 increases, the closure region 4 being pivoted about a pivot axis lying essentially in the bulge 2. The bulge 2 located in the closure means 1 thus functions as a joint, about the axis of which the closure region 4 is pivoted out of the plane of the cover mirror 9.

Bei der in den Fig. 1 bis Fig. 4 gezeigten Variante ist zudem ein an dem Betätigungsmittel 6 angeordnetes zusätzliches Verschlusselement vorgesehen, das an der dem Verschlussmittel 1 gegenüberliegenden Seite des Dosenspiegels 9 zum Verschließen der Ausgießöffnung 10 angeordnet ist, wobei aufgrund der Übersichtlichkeit auf die Darstellung des zusätzlichen Verschlusselementes verzichtet wurde. Dieses Verschlusselement weist eine im wesentlichen der Ausgießöffnung 10 angepasste Form auf und gibt beim Verschieben des Betätigungsmittels 6 ebenfalls die Trinköffnung 10 frei.In the in the 1 to 4 In the variant shown, an additional closure element arranged on the actuating means 6 is also provided, which is arranged on the side of the can mirror 9 opposite the closure means 1 for closing the pouring opening 10, the illustration of the additional closure element being dispensed with due to the clarity. This closure element has a shape substantially adapted to the pouring opening 10 and also opens the drinking opening 10 when the actuating means 6 is moved.

In Fig. 5 und Fig. 6 ist ein nicht-erfindungsgemäßes Beispiel dargestellt. Das Verschlussmittel 1 ist wiederum an der Unterseite des Deckelspiegels 9 angeordnet, um mit seinem Verschlussbereich 4 die Ausgießöffnung 10 zu verschließen. Zwischen Verschlussbereich 4 und Deckelspiegel 9 ist ein Dichtungsmaterial 13 angeordnet, das zusätzlich abdichtet und so ein Auslaufen des Behälterinhaltes verhindert. Das Verschlussmittel 1 wird in der in Fig. 5 dargestellten Schließstellung einerseits durch eine aufgrund der Gestalt des aus elastischem Material gefertigten Verschlussmittels resultierenden Vorspannung gegen die Ausgießöffnung gepresst; andererseits erhöht sich der Anpressdruck weiter, wenn in dem Behälter beispielsweise kohlensäurehältige Getränke abgefüllt sind. Des Weiteren ist wiederum im Bereich des Gelenks 2 ein elastischer Bereich 21 vorgesehen, der ein Wegklappen des Verschlussbereiches 4 beim Betätigen des Betätigungsmittels 6 unterstützt.In 5 and 6 a non-inventive example is shown. The closure means 1 is in turn arranged on the underside of the lid mirror 9 in order to close the pouring opening 10 with its closure region 4. A sealing material 13 is arranged between the closure area 4 and the lid mirror 9, which additionally seals and thus prevents the contents of the container from leaking. The closure means 1 is in the Fig. 5 shown closed position pressed on the one hand by a bias resulting from the shape of the closure means made of elastic material against the pouring opening; on the other hand, the contact pressure increases further if, for example, carbonated drinks are filled in the container. Furthermore, an elastic region 21 is again provided in the region of the joint 2, which supports the closure region 4 from folding away when the actuating means 6 is actuated.

Das Betätigungsmittel 6 ist bei dieser Ausführung ein im Wesentlichen zylindrischer Hebel, der durch ein Bohrung des Deckelspiegels 9 hindurch mit dem Verschlussmittel 1 verbunden ist. Hierbei ist der Hebel entweder einstückig mit dem Verschlussmittel 1 gefertigt oder wird beispielsweise über eine Schraubverbindung an diesem befestigt. An seinem unteren, dem Deckelspiegel zugewandten Ende, weist der Hebel 6 eine Einschnürung 14 auf, an die wiederum ein Bereich 15 mit dem ursprünglichen Durchmesser des Hebels 6 anschließt. Beim Herunterdrücken des Hebels 6 bewegt sich, wie in Fig. 6 gezeigt, das Verschlussmittel 1 in das Behälterinnere und gibt die Ausgießöffnung 10 frei. Der als Rastnase fungierende Bereich 15 gleitet hierbei unterhalb des Deckelspiegels 9, während die Kante des Deckelspiegels 9 in die Einschnürung 14 eingreift. Auf diese Weise ist der Verschlussbereich 4 in seiner weggeklappten Position fixiert und der Behälter kann entleert werden. Um die Ausgießöffnung 10 wieder zu verschließen, muss lediglich der Hebel 6 in die der Ausgießöffnung gegenüberliegende Richtung gedrückt werden, damit die Kante des Deckelspiegels 9 aus der Einschnürung 14 wieder herausgleitet und die Rastnase wieder freigegeben wird.In this embodiment, the actuating means 6 is an essentially cylindrical lever which is connected to the closure means 1 through a bore in the cover mirror 9. Here, the lever is either in one piece with the Closure means 1 manufactured or is attached to this, for example via a screw connection. At its lower end facing the cover mirror, the lever 6 has a constriction 14, which in turn is adjoined by a region 15 with the original diameter of the lever 6. When pushing the lever 6 moves, as in Fig. 6 shown, the closure means 1 into the interior of the container and releases the pouring opening 10. The area 15 acting as a locking lug slides below the cover mirror 9, while the edge of the cover mirror 9 engages in the constriction 14. In this way, the closure area 4 is fixed in its folded-away position and the container can be emptied. In order to close the pouring opening 10 again, only the lever 6 has to be pressed in the direction opposite the pouring opening, so that the edge of the lid mirror 9 slides out of the constriction 14 again and the latching lug is released again.

Der Deckel von Fig. 7 und Fig. 8 unterscheidet sich von den oben beschriebenen Deckeln dadurch, dass eine vergrößerte Ausgießöffnung 10 seitlich versetzt angeordnet ist und dass zusätzlich eine Belüftungsöffnung 10a vorgesehen ist. Beide Öffnungen 10 und 10a sind durch ein entsprechend ausgebildetes Verschlussmittel 1 verschließbar. Ein weiteres Verschlusselement ist in einer nicht dargestellten Ausführung der Erfindung zusätzlich an der Außenseite des Dosenspiegels 9 angeordnet und verhindert ein unbeabsichtigtes Verschwenken des Verschlussbereichs 4 beispielsweise während des Transports der Getränkedose in einer Tasche.The lid of 7 and 8 differs from the lids described above in that an enlarged pouring opening 10 is arranged laterally offset and in addition that a ventilation opening 10a is provided. Both openings 10 and 10a can be closed by a correspondingly designed closure means 1. In a not shown embodiment of the invention, a further closure element is additionally arranged on the outside of the can mirror 9 and prevents the closure area 4 from being inadvertently pivoted, for example during the transport of the beverage can in a pocket.

In den Figuren ist deutlich zu erkennen, dass das Verschlussmittel 1 lediglich im Bereich des Deckelspiegels 9 angeordnet ist und der Randbereich des Deckels 8 freibleibt. Zur Montage des Verschlussmittels 1 muss dieses lediglich mit seinem Befestigungsteil 3 an der Unterseite des Deckels 8 derart befestigt werden, dass der Verschlussbereich 4 die Ausgießöffnung 10 vollständig abdeckt. Danach wird durch eine im Deckelspiegel 9 befindliche Ausnehmung 11 oder Bohrung das Betätigungsmittel 6 an dem Verschlussmittel 1 befestigt. Anschließend kann der Deckel 8 auf bekannte Weise auf dem Behälter befestigt werden, ohne dass spezielle Vorkehrungen getroffen oder Veränderungen an den hierfür eingesetzten Maschinen vorgenommen werden müssen.It can be clearly seen in the figures that the closure means 1 is only arranged in the area of the cover mirror 9 and the edge area of the cover 8 remains free. To assemble the closure means 1, it only has to be fastened with its fastening part 3 to the underside of the cover 8 in such a way that the closure region 4 completely covers the pouring opening 10. Thereafter, the actuating means 6 is fastened to the closure means 1 through a recess 11 or bore located in the cover mirror 9. Subsequently, the lid 8 can be attached to the container in a known manner without taking special precautions or having to make changes to the machines used for this purpose.

Eine weitere Variante ist den Figuren 9 bis 10b zu entnehmen. Wiederum ist am Deckel 8 einer Getränkedose ein Betätigungsmittel 6 mit einem hakenförmigen Fortsatz 61, der den Dosenspiegel 9 durchdringt, angeordnet. Der Fortsatz 61 rastet in der Schließstellung (Fig. 9 bzw. Fig. 10b) in eine passenden Ausnehmung 11 des unterhalb des Dosenspiegels angeordneten Verschlussmittels 1 ein. Zum Öffnen der Trinköffnung 10 durch Verschieben des Betätigungsmittels 6 in Pfeilrichtung in einer Ebene parallel zum Dosenspiegel 9 wird der Fortsatz 61 entlang einer Abschrägung 16 der Ausnehmung 11 bewegt, so dass sich der Verschlussbereich 4 des Verschlussmittels 1 entlang des gekrümmten Pfeils in das Doseninnere bewegt, wobei die Verschwenkung über ein Gelenk 2, das als Bereich mit geringerem Materialquerschnitt ausgebildet ist, erfolgt.Another variant is the Figures 9 to 10b refer to. In turn, an actuating means 6 with a hook-shaped extension 61, which penetrates the can mirror 9, is arranged on the lid 8 of a beverage can. The extension 61 snaps into the closed position ( Fig. 9 respectively. Fig. 10b ) into a suitable recess 11 of the closure means 1 arranged below the can level. To open the drinking opening 10 by moving the actuating means 6 in the direction of the arrow in a plane parallel to the can level 9 Extension 61 moves along a bevel 16 of the recess 11, so that the closure area 4 of the closure means 1 moves into the interior of the can along the curved arrow, the pivoting taking place via a joint 2, which is designed as an area with a smaller material cross section.

Eine schematische Darstellung der Schließstellung bzw. Offenstellung
in einem nicht-erfindungsgemäßen Beispiel kann den Figuren 11a bis 11d entnommen werden. Wiederum ist ein Betätigungsmittel 6 vorgesehen, dass aus einer Schließstellung (Fig. 11a bzw. Fig. 11c) über eine translatorische, im Wesentlichen parallel zu der Ebene des Dosenspiegels 9 verlaufende Schiebebewegung in eine Offenstellung (Fig. 11b bzw. Fig. 11d) überführt wird. Hierbei greift ein Fortsatz 61 des Betätigungsmittels 6 in eine Auflaufschräge 16 einer Ausnehmung 11 des Verschlussmittels 1 ein, wodurch der Verschlussbereich 4 um das Gelenk 2, das hier als Materialverdünnung ausgebildet ist, in das Doseninnere verschwenkt wird. Die Auflaufschräge 16 kann hierbei auch verschieden Bereiche mit unterschiedlicher Schräge aufweisen, so dass während des Öffnens der Getränkedose durch Verschieben des Betätigungsmittels 6 zunächst eine hohe Krafteinwirkung auf das Verschlussmittel 1 erzeugt wird, um den möglicherweise herrschenden Überdruck in der Getränkedose zu überwinden, und anschließend eine geringere Krafteinwirkung zur vollständigen Freilegung der Ausgießöffnung 10 durch eine geringere Neigung der Auflaufschräge 16 erzielt wird. In der Schließstellung fungiert das Betätigungsmittel 6 gleichzeitig auch als zusätzliches Verschlusselement zur Sicherung der Ausgießöffnung 10.A schematic representation of the closed position or open position
in an example not according to the invention, the Figures 11a to 11d be removed. In turn, an actuating means 6 is provided that from a closed position ( Fig. 11a respectively. Fig. 11c ) via a translatory, essentially parallel to the plane of the can mirror 9 sliding movement into an open position ( Fig. 11b respectively. Fig. 11d ) is transferred. In this case, an extension 61 of the actuating means 6 engages in a run-up slope 16 of a recess 11 in the closure means 1, as a result of which the closure region 4 is pivoted into the interior of the can around the joint 2, which is designed here as a material thinner. The run-up slope 16 can also have different areas with different slopes, so that during the opening of the beverage can by moving the actuating means 6, a high force is initially generated on the closure means 1 in order to overcome the possibly prevailing excess pressure in the beverage can, and then one less force for complete exposure of the pouring opening 10 is achieved by a lower inclination of the ramp 16. In the closed position, the actuating means 6 also functions as an additional closure element for securing the pouring opening 10.

Die in den Fig. 12a bis Fig. 12d gezeigte Ausführung des nicht-erfindungsgemäßen Deckels 8 beschreibt ein Betätigungselement 6, das neben den Fortsatz 61 zusätzlich ein elastisches Druckelement 62, das in ein Widerlager 111 einrastet, sich dabei scharnierartig aufstellt und so bei kleinem Bedienweg des Betätigungsmittels 6 einen hohen Öffnungsweg des Verschlussbereiches 4 erzeugt. Damit kann besonders einfach die hohe Öffnungskraft für die Entlüftung beim erstmaligen Öffnen der Getränkedose erzeugt werden.The in the 12a to 12d shown embodiment of the cover 8 not according to the invention describes an actuating element 6 which, in addition to the extension 61, also has an elastic pressure element 62 which snaps into an abutment 111, is set up in a hinge-like manner and thus produces a long opening travel of the closure region 4 with a small operating path of the actuating means 6 . This makes it particularly easy to generate the high opening force for ventilation when the beverage can is opened for the first time.

In den Fig. 13a und Fig. 13b ist eine Ausführung der Erfindung gezeigt, bei welcher das Betätigungsmittel 6 um eine Achse normal auf den Dosenspiegel 9 verschwenkt wird, wobei ein Teilbereich 63 des Betätigungsmittels unlösbar mit dem Dosenspiegel 9 verbunden ist. Bei Verdrehen des Betätigungsmittels 6 zum erstmaligen Öffnen der Getränkedose entlang des Pfeils (Fig. 13b) wird eine Sollbruchstelle 64 getrennt. Damit wird gleichzeitig auch ein Sicherheitselement erhalten, das dem Endverbraucher anzeigt, ob die Getränkedose bereits geöffnet wurde.In the Figures 13a and 13b An embodiment of the invention is shown, in which the actuating means 6 is pivoted normally about an axis onto the can mirror 9, a partial region 63 of the actuating means being non-detachably connected to the can mirror 9. When the actuating means 6 is rotated to open the beverage can along the arrow ( Fig. 13b ) a predetermined breaking point 64 is separated. At the same time, a security element is also obtained which indicates to the end user whether the beverage can has already been opened.

Eine alternative Ausführung des erfindungsgemäßen Deckels 8 ist in den Figuren 14a bis 14c, gezeigt, bei welcher das Betätigungsmittel ebenfalls in einer Drehbewegung aus der Schließstellung in die Offenstellung gebracht wird, wobei eine Helix 65 zur vertikalen Bewegung (Pfeil in Fig. 14d) des Verschlussmittels 1 vorgesehen ist. Der Übersicht halber wurde in der Fig. 14c das Verschlussmittel 1 und in der Fig. 14d die Helix 65 nicht dargestellt.An alternative embodiment of the cover 8 according to the invention is shown in FIGS Figures 14a to 14c , shown, in which the actuating means is also brought in a rotary movement from the closed position into the open position, a helix 65 for vertical movement (arrow in FIG Fig. 14d ) of the closure means 1 is provided. For the sake of clarity, the 14c the closure means 1 and in the Fig. 14d the Helix 65 not shown.

Bei der in den Fig. 15a bis Fig. 17b dargestellten Variante handelt es sich um ein Verschlussmittel 1, das als Zweikomponenten-Spritzgussteil ausgebildet ist. Der Spritzgussteil besteht aus einem Verschlussbereich 4 aus im Wesentlichen starrem Material sowie einem dreigeteilten Befestigungsteil 3, wobei zwei außenliegende Befestigungsbereiche 3', 3" über eine Erhebung 31 verfügen, über die das Verschlussmittel 1 mit dem Dosenspiegel 9 verbindbar ist. Der zwischen den beiden Befestigungsbereichen 3', 3" befindliche Mittelteil bildet ein Federelement,
das den Verschlussbereich 4 in die Schließposition rückstellt. Hierbei ist ein Vorsprung 35 auf dem Federelement vorgesehen, der eine Beabstandung des Federelementes zum Dosenspiegel 9 bewirkt, wodurch die für das Verschließen der Ausgießöffnung 10 notwendige Vorspannung auf den mit dem Federelement bevorzugterweise einstückig ausgebildeten Verschlussbereich 4 des Verschlussmittels 1 aufgebaut wird.In the in the 15a to 17b The variant shown is a closure 1, which is designed as a two-component injection molded part. The injection molded part consists of a closure region 4 made of essentially rigid material and a three-part fastening part 3, two outer fastening regions 3 ′, 3 ″ having an elevation 31 by means of which the closure means 1 can be connected to the can mirror 9. The one between the two fastening regions 3 ', 3 "central part forms a spring element,
that resets the closure area 4 into the closed position. Here, a projection 35 is provided on the spring element, which causes the spring element to be spaced apart from the can mirror 9, as a result of which the pretension necessary for closing the pouring opening 10 is built up on the closure region 4 of the closure means 1, which is preferably made in one piece with the spring element.

Das Verschlussmittel 1 weist zudem ein Dichtungselement 13 auf, dessen Aufbau insbesondere der Fig. 16 zu entnehmen ist. Dieses Dichtungselement 13 aus flexiblem Material dichtet zum einen das Verschlussmittel 1 gegen den Rand des Dosendeckels 8 ab, wobei es entlang der Außenkante des Verschlussmittels 1 angeordnet ist. Zum anderen ist es zwischen Befestigungsteil 3 und Verschlussbereich 4 angeordnet und fungiert so als Gelenk 20. In der in Fig. 17b dargestellten Ausführung weist das Verschlussmittel 1 zusätzlich über einen Bereich 2 mit reduziertem Materialquerschnitt, der ebenfalls die Verschwenkung des Verschlussbereichs 4 in das Doseninnere unterstützt. In einer anderen Variante der Erfindung fungiert dieser Bereich als alleiniges Gelenk, so dass Befestigungsteil 3 und Verschlussbereich 4 als zwei getrennte Teile ausgeführt sind (nicht dargestellt).The closure means 1 also has a sealing element 13, the structure of which in particular the Fig. 16 can be seen. This sealing element 13 made of flexible material firstly seals the closure means 1 against the edge of the can lid 8, it being arranged along the outer edge of the closure means 1. On the other hand, it is arranged between the fastening part 3 and the closure region 4 and thus functions as a joint 20 Fig. 17b In the illustrated embodiment, the closure means 1 additionally has an area 2 with a reduced material cross section, which also supports the pivoting of the closure area 4 into the interior of the can. In another variant of the invention, this region functions as the sole joint, so that the fastening part 3 and the closure region 4 are designed as two separate parts (not shown).

Die in der Fig. 18 gezeigte Variante des erfindungsgemäßen Deckels 8 weist das zuvor besprochene Dichtungselement 13 auf sowie ein verdrehbares Betätigungselement 6, das über ein Helixelement 65 auf das unterhalb des Dosenspiegels 9 angeordnete Verschlussmittel 1 einwirkt. Das Federelement 32 des Befestigungsbereichs 3 ist hierbei einstückig mit dem Verschlussbereich 4 ausgebildet und bewirkt so die benötigte Vorspannung des Verschlussbereichs 4.The in the Fig. 18 shown variant of the lid 8 according to the invention has the previously discussed sealing element 13 and a rotatable actuating element 6 which acts via a helix element 65 on the closure means 1 arranged below the can level 9. The spring element 32 of the fastening region 3 is in this case formed in one piece with the closure region 4 and thus brings about the required pretensioning of the closure region 4.

In der Fig. 19a bis Fig. 20 ist eine weitere Ausführung des erfindungsgemäßen Deckels 8 mit zugehörigem Betätigungsmittel 6 dargestellt, wobei das Verschlussmittel 1 unterhalb des Dosenspiegels 9 angeordnet ist. Das Betätigungsmittel 6 ist in der Fig. 19a in der Schließstellung gezeigt, wobei es gleichzeitig die Ausgießöffnung 10 verschließt. In der Fig. 19b ist das Betätigungsmittel 6 derart parallel zu der Ebene des Dosenspiegels 9 verschwenkt, dass es die Trinköffnung 10 freigibt, der Verschlussbereich 4 des Verschlussmittels 1 jedoch noch nicht in das Doseninnere geklappt ist. Durch weiteres Verdrehen des Betätigungsmittels 6 beispielsweise im Uhrzeigersinn zu den Befestigungen 31 hin, bewirkt ein durch den Dosenspiegel 9 ragender Dorn 61 (Fig. 20) ein Verschwenken des Verschlussbereiches 4 in das Doseninnere zur Freigabe der Trinköffnung 10. In Fig. 20 sind nochmals drei Positionen des in dieser Ausführung der Erfindung entlang des Dosenspiegels 9 verdrehbaren Betätigungsmittels 6 gezeigt. In der Position 41 verdeckt das Betätigungsmittel 6 die Ausgießöffnung 10 zur Gänze, so dass der Verschlussbereich 4 des Verschlussmittels nicht unbeabsichtigt in das Doseninnere gedrückt werden kann. In der Position 42 ist die Ausgießöffnung 10 freigelegt, jedoch noch von dem Verschlussbereich 4 des Verschlussmittels 1 verschlossen. In der Position 43 schließlich ist die Trinköffnung 10 zur Gänze freigelegt und der Inhalt der Dose kann entnommen werden.In the 19a to 20 A further embodiment of the cover 8 according to the invention is shown with the associated actuating means 6, the closure means 1 being arranged below the can level 9. The actuating means 6 is in the Fig. 19a shown in the closed position, at the same time closing the pouring opening 10. In the Fig. 19b the actuating means 6 is pivoted parallel to the plane of the can level 9 in such a way that it opens the drinking opening 10, but the closure area 4 of the closure means 1 has not yet been folded into the inside of the can. By further turning the actuating means 6, for example clockwise, towards the fastenings 31, a mandrel 61 projecting through the can mirror 9 ( Fig. 20 ) a pivoting of the closure area 4 into the interior of the can to open the drinking opening 10. In Fig. 20 Three positions of the actuating means 6 which can be rotated along the can level 9 in this embodiment of the invention are shown again. In position 41, the actuation means 6 completely covers the pouring opening 10, so that the closure area 4 of the closure means cannot be inadvertently pressed into the interior of the can. In position 42, the pouring opening 10 is exposed, but is still closed by the closure area 4 of the closure means 1. Finally, in position 43, the drinking opening 10 is completely exposed and the contents of the can can be removed.

In den Fig. 21a und Fig. 21b ist eine Ausführung des erfindungsgemäßen Deckels 8 gezeigt, bei welchem das Betätigungsmittel 6 beispielsweise durch Verdrehen von der Ausgießöffnung 10 weggeschwenkt wird, während gleichzeitig über einen Fortsatz 61 eine vertikale Kraft (Doppelpfeil) auf das Verschlussmittel 1 ausgeübt wird, das in dieser Variante der Erfindung ohne Gelenk ausgeführt ist und damit während der Vertikalbewegung im Wesentlichen parallel zum Dosenspiegel 9 angeordnet bleibt.In the Figures 21a and 21b An embodiment of the cover 8 according to the invention is shown, in which the actuating means 6 is pivoted away from the pouring opening 10, for example by twisting, while at the same time a vertical force (double arrow) is exerted on the closure means 1 via an extension 61, which in this variant of the invention without Is executed joint and thus remains arranged essentially parallel to the can level 9 during the vertical movement.

Im Gegensatz hierzu weist bei der in den Fig. 22a und Fig. 22b dargestellten Variante das Verschlussmittel 1 ein Gelenk 2 auf, das hier durch Verringerung des Materialquerschnitts gebildet ist, so dass bei Krafteinwirkung über den Fortsatz 61 eine Kippbewegung des Verschlussbereichs 4 des Verschlussmittels 1 erzielt wird.In contrast, in the case of the 22a and 22b In the variant shown, the closure means 1 has a joint 2, which is formed here by reducing the material cross section, so that when the force exerts on the extension 61, the closure region 4 of the closure means 1 is tilted.

Bei der in den Fig. 23a und Fig. 23b vorgestellten Variante der Erfindung, weist das Betätigungsmittel 6 eine Rastnocke 66 auf, die im dargestellten Schließzustand in die Ausgießöffnung 10 einrastet und auf diese Weise das Betätigungsmittel 6 mit erhöhtem Widerstand in dieser Position fixiert. Ebenso kann vorgesehen sein, dass die Rastnocke 66 in eine speziell in dem Dosenspiegel geschaffene Ausnehmung einrastet.In the in the Figures 23a and 23b presented variant of the invention, the actuating means 6 has a latching cam 66 which engages in the pouring opening 10 in the illustrated closed state and in this way fixes the actuating means 6 in this position with increased resistance. It can also be provided that the detent cam 66 engages in a recess specially created in the can mirror.

In den Fig. 24a bis Fig. 24c ist eine ähnliche Ausführung des erfindungsgemäßen Deckels 8 gezeigt, bei welcher neben der Rastnocke 66 zusätzlich eine Auflagenocke 67 aufweist, wobei bei Ausübung einer Druckkraft (Pfeil in Fig. 24 c) auf ein Ende des Betätigungsmittels 6 durch das Widerlager der Auflagenocke 67 die Rastnocke 66 angehoben wird und das Betätigungsmittel 6 anschließend aus der Schließposition in die Offenposition gleitet. Der Übersicht halber wurde in den Figuren 24b und 24c auf die Darstellung des Fortsatzes 61 und dessen Einwirkung auf das Verschlussmittel 1 verzichtet.In the 24a to 24c A similar embodiment of the cover 8 according to the invention is shown, in which, in addition to the locking cam 66, there is also a support cam 67 24 c) on one end of the actuating means 6, the locking cam 66 is raised by the abutment of the support cam 67 and the actuating means 6 then slides from the closed position into the open position. For the sake of clarity, the Figures 24b and 24c the representation of the extension 61 and its action on the closure means 1 are omitted.

Bei der in den Fig. 25a und Fig. 25b gezeigten nicht-erfindungsgemäßen Variante ist ein Deckel 8 mit einem Verschlussmittel 1 gezeigt, das wiederum unterhalb des Deckelspiegels 9 positioniert ist. Dieses Verschlussmittel 1 weist vier Ausnehmungen 400 auf, die jeweils einen Befestigungsbereich 30 zur Befestigung an der Unterseite des Dosenspiegels 9 sowie einen Hebelbereich 50 aufweisen, der den Befestigungsbereich 30 mit dem Verschlussbereich 4 verbindet. Bei Verschieben des Betätigungsmittels 6 zum Öffnen der Getränkedose bewegt sich der Verschlussbereich 4 entlang einer Kreisbahn, deren Radius der Länge des Hebelbereiches 50 entspricht, wobei der Verschlussbereich 4 parallel zum Dosenspiegel 9 ausgerichtet ist. Fig. 26 zeigt das Verschlussmittel aus den Fig. 25a und 25b in einer Ansicht von oben sowie in einer Seitenansicht.
Durch die Anbringung des in der Regel einstückigen Verschlussmittels auf verdrehfeste Weise, beispielsweise durch Ankleben oder Anlöten an der Unterseite des Deckelspiegels, ist eine rasche Montage des Verschlussmittels auf einem handelsüblichen Deckel möglich, wobei gar keine oder nur geringfügige Veränderung des Deckels, beispielsweise eine einfache Ausstanzung für die Durchführung des Betätigungsmittels durch den Deckel, notwendig sind. Insbesondere der Randbereich des Deckels bleibt unverändert, so dass ein Aufsetzen und Befestigen des Deckels auf dem Behälter, insbesondere auf der Getränkedose, auf die übliche Weise erfolgen kann.In the in the Figures 25a and 25b shown variant not according to the invention, a lid 8 is shown with a closure means 1, which in turn is positioned below the lid mirror 9. This closure means 1 has four recesses 400, each of which has a fastening region 30 for fastening to the underside of the can mirror 9 and a lever region 50 which connects the fastening region 30 to the closure region 4. When the actuating means 6 is moved to open the beverage can, the closure region 4 moves along a circular path, the radius of which corresponds to the length of the lever region 50, the closure region 4 being aligned parallel to the can mirror 9. Fig. 26 shows the closure means from the 25a and 25b in a view from above and in a side view.
By attaching the generally one-piece closure means in a torsion-proof manner, for example by gluing or soldering to the underside of the cover mirror, the closure means can be quickly mounted on a commercially available cover, with little or no change in the cover, for example simple punching out are necessary to carry out the actuating means through the cover. In particular, the edge region of the lid remains unchanged, so that the lid can be placed and fastened on the container, in particular on the beverage can, in the usual way.

Es versteht sich, dass die oben beschriebenen Ausführungsbeispiele in nicht-einschränkender Weise für die Erfindung zu betrachten sind. Insbesondere die Form des Verschlussmittels kann an die jeweilige zu verschließende Öffnung angepasst werden. Ebenso ist auch die Form des Betätigungsmittels nicht auf die beschriebenen Formen beschränkt, sondern kann jede Form annehmen, die für eine Fixierung des Verschlussmittels in einer weggeklappten Position geeignet ist. Des Weiteren können auch zusätzliche Rückstellelemente vorgesehen sein, die das Verschlussmittel in eine Schließstellung zwingen.It is understood that the exemplary embodiments described above are to be considered in a non-restrictive manner for the invention. In particular, the shape of the closure means can be adapted to the respective opening to be closed. Likewise, the shape of the actuating means is not limited to the shapes described, but can take any shape that is suitable for fixing the locking means in a folded-away position. Furthermore, additional reset elements can also be provided, which force the closure means into a closed position.
