Definitions
- the invention relates to a lid of a container, in particular a beverage can, with a substantially flat lid mirror, and at least one arranged on the lid mirror pouring opening, which is gas-tight and / or liquid-tightly closed via at least one closure element, wherein the closure element via an actuating element of a Closed position is movable into an open position, and at least one pressure compensation device is provided with at least one pressure equalization opening, which cooperates with the actuating element, wherein at least one closing element for closing the pressure equalization opening is provided in position of the actuating element in the closed position, and upon movement of the actuating element from the closed position in the open position, the at least one pressure compensation opening can be exposed from, according to the preamble of claim 1.
- Containers especially beverage cans, are usually filled with carbonated beverages, wherein the pressure within the beverage can can be up to 6 bar.
- pressure within the beverage can can be up to 6 bar.
- opening such pressurized container for example by means of a pull tab, there is a sudden pressure drop within the can, often spouting liquid out of the can. Since this sudden pressure equalization due to the risk of contamination is undesirable, devices have been developed to prevent this.
- Another way to reduce the sudden venting of a beverage can is to gradually expose the can opening.
- Such a procedure with associated can closure is in the WO 2007/128810 A1 described.
- a base plate is gradually lowered over a cam profile to release the can opening.
- the EP 1 796 974 B1 discloses a closure device for a beverage container of the type mentioned, in which an actuating element is provided which has a fixing and a sliding element to release a drinking opening and close again.
- a disadvantage of this device is its complicated structure and in practice only insufficient tightness after first opening, especially over a longer period of time.
- WO 00/63091 A1 discloses the features of the preamble of claim 1 and relates to a closure with an integrated straw and a venting tube, both of which are resilient, and wherein an element is provided which is located on the underside of the closure and is designed to hold the two tubes can be closed by simultaneous compression.

- the longitudinal axis of the tubular element can in this case be normal to the cover mirror plane or substantially parallel to it. Beverage cans and their associated closure devices must withstand high pressures inside the can. This results in the following after filling and closing the beverage can pasteurization pressures of 6 bar or more, which in particular the pressure compensation device must withstand.
- the tube element is folded over when the actuating element is moved into the closed position, thereby facilitating closure and opening of the closure device.
- a high closure pressure is exerted on the pressure compensation opening, which in particular resists temporarily or permanently occurring high internal pressures of the beverage can.
- the height of the closure device remains low, because the elements of the closure device according to the invention can be kept small in their dimensions. In particular, it does not exceed the beaded edge of the beverage can, which is extremely undesirable in the beverage industry for manufacturing reasons.
- the pipe element can be closed via an operating element which cooperates with the actuating element.
- This operating element usually represents the connecting element between the actuating element, which is operated by the user for opening and reclosing, in particular, the beverage can, and the closure element, which closes the pouring opening in the closed position in a gas- and liquid-tight manner.
- the operating element is such is formed that it acts directly or indirectly on the pipe element.
- the operating element has at least one deflecting element, which closes the tubular element in the closed position of the actuating element.
- the deflection element which is made in particular of at least slightly elastic material, acts resiliently or rigidly on the tubular element and closes it by narrowing the cross-section up to the buckling of the tubular element.
- a particularly simple construction of the closure device is obtained if the actuating element and the operating element are made in one piece, preferably made of plastic.
- the operating element with the actuating element in detachable connection, which facilitates the installation of the closure device substantially.

- the at least one actuating element relative to the lid mirror is rotatable.
- a closure element For closing the pouring opening, a closure element is provided, which is particularly preferably substantially vertically pivotable with respect to the lid.
- the pressure compensation opening is arranged in the actuating element, wherein preferably the pressure compensation opening has a seal which is in communication with a peripheral seal of the closure element.
- the peripheral seal of the closure element has the task of preventing leakage of liquid and / or gas, in particular carbonic acid in the closed position of the closure element.
- a simple production of the closure element is possible when the seal of the pressure compensation opening with the peripheral seal of the closure element in one piece, in particular by means of a suitable two-component injection molding process is made.
- the lid according to the invention is particularly suitable for containers whose pouring opening is resealable.
- a first embodiment of the invention is in the Fig. 1 to Fig. 1g shown.
- a cover 100 is provided with a cover mirror 101 and a flanged edge 102, as can be found, for example, in beverage cans, wherein the cover 100 has a pouring opening 103 which can be closed and exposed again by a closure element 120 arranged below the lid level 101.
- the closure element 120 closes the pouring opening 103 gas and liquid-tight when an associated with the closure element 120 actuator 110 in the in the Fig. 1a respectively.
- Fig. 1e is shown closed position.
- the closure element 120 has a receptacle 121 for a cooperating with the actuating element 110 operating element 111, in which the operating element 111 along a ramp 122 is movable.
- a tubular element 124 is provided, which is in communication with a pressure equalization opening 123 in the closure element 120.
- the tube element 124 which is made of a flexible material, is bent in such a way by a deflection element 112 arranged on the operating element 111 ( Figs. 1b . Fig. 1e ) that the cross section of the tubular element 124 is changed and thus the connection of the pressure compensation opening 123 is interrupted with the environment of the container ( Fig. 1e ).
- This simple or multiple kinking causes a gas and liquid-tight closure of the pressure compensation opening 123.
- the tubular element 124 is arranged in this embodiment at the run-on slope 122 of the closure element 120, wherein by moving the actuating element 110 in the direction of the arrow in Fig. 1e initially the bent pipe element 124 released by the deflecting element 112 of the operating element 111 is then, so that the tube member 124 straightens due to its elastic properties, and thereby the pressure compensation opening 123 is released ( Fig. 1f ) without opening the pouring opening 103. In this way, a pressure equalization of the pressurized beverage can with the environment, without the contents of the can is ejected, because in turn the actuator 110 optionally acts as a splash guard.
- FIGS. 2 to 5 a second variant of the invention is shown.
- Fig. 2 a preferred embodiment of the actuating element 110 is shown, which is designed as a two-part slide, wherein in this illustration pouring opening 103 and pressure equalization opening 123 are closed.
- a fixing element 110a To open the beverage can, first a fixing element 110a must be raised or pivoted ( Figs. 3 and Fig. 4 ), in order subsequently to ventilate the can by displacing a sliding element 110c and thereby causing the displacement of the operating element 111 and thereby simultaneously or in a further step release the pouring opening 103 (FIG. Fig. 5 and Fig. 6 ).
- a pressure compensation opening 123 is arranged, which has an elastic seal 130 for sealing the pressure equalization opening 123, which is made in one piece with a circumferential seal 131 of the closure element 120 made of elastic material.
- the tubular element 124 also made of elastic material is closed by a deflecting element 112 of the operating element 111 when the actuating element 110 is in the closed position ( Fig. 2 ).
- the deflecting element 112 is pressed against the tubular element 124 via guide elements, for example elevations on the surface of the closure element 120.
- the tubular element 124 is compressed or bent over, whereby a gas- and liquid-tight closure of the pressure compensation opening is obtained.
- the operating element 111 is displaced in such a way that the deflecting element 112 is moved away from the tubular element 124 so that it expands or rests again due to its elastic properties so that the pressure equalizing opening 123 comes into contact with the environment and a pressure equalization can take place.
- the ventilation of the beverage can already takes place before the displacement of the actuating element 110, so that during the ventilation process, the closure element 120 still remains in the closed position.
- a pin 110b of the fixing element 110a engages in the closed position of the actuating element 110 in a receptacle 125 of the closure element 120 in the immediate vicinity of the pressure equalization opening 123, whereby the deflecting element 112 is slightly bent and pressed against the tubular element 124, and this in the sequence on the closed manner above, in particular kinked (not shown).

Description
Die Erfindung betrifft einen Deckel eines Behälters, insbesondere einer Getränkedose, mit einem im Wesentlichen ebenen Deckelspiegel, sowie zumindest einer an dem Deckelspiegel angeordneten Ausgießöffnung, die über zumindest ein Verschlusselement gas- und/oder flüssigkeitsdicht verschließbar ist, wobei das Verschlusselement über ein Betätigungselement aus einer Geschlossenposition in eine Offenposition bewegbar ist, und zumindest eine Druckausgleichseinrichtung mit zumindest einer Druckausgleichsöffnung vorgesehen ist, die mit dem Betätigungselement zusammenwirkt, wobei zumindest ein Schließelement zum Verschließen der Druckausgleichsöffnung bei Stellung des Betätigungselementes in der Geschlossenposition vorgesehen ist, und bei Bewegung des Betätigungselementes aus der Geschlossenposition in die Offenposition die zumindest eine Druckausgleichsöffnung aus freilegbar ist, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a lid of a container, in particular a beverage can, with a substantially flat lid mirror, and at least one arranged on the lid mirror pouring opening, which is gas-tight and / or liquid-tightly closed via at least one closure element, wherein the closure element via an actuating element of a Closed position is movable into an open position, and at least one pressure compensation device is provided with at least one pressure equalization opening, which cooperates with the actuating element, wherein at least one closing element for closing the pressure equalization opening is provided in position of the actuating element in the closed position, and upon movement of the actuating element from the closed position in the open position, the at least one pressure compensation opening can be exposed from, according to the preamble of claim 1.
Behälter, insbesondere Getränkedosen, sind zumeist mit kohlensäurehältigen Getränken befüllt, wobei der Druck innerhalb der Getränkedose bis zu 6 bar betragen kann. Beim Öffnen derartiger unter Druck stehender Behälter, beispielsweise mittels einer Aufreißlasche, kommt es zum schlagartigen Druckabfall innerhalb der Dose, wobei häufig Flüssigkeit aus der Dose herausspritzt. Da dieser schlagartige Druckausgleich aufgrund der Verschmutzungsgefahr unerwünscht ist, wurden Einrichtungen entwickelt, die dies vermeiden sollen.Containers, especially beverage cans, are usually filled with carbonated beverages, wherein the pressure within the beverage can can be up to 6 bar. When opening such pressurized container, for example by means of a pull tab, there is a sudden pressure drop within the can, often spouting liquid out of the can. Since this sudden pressure equalization due to the risk of contamination is undesirable, devices have been developed to prevent this.

Die im Stand der Technik beschriebenen Lösungen weisen nur einen beschränkten Schutz hinsichtlich des Herausspritzens vom Doseninhalt auf oder sie sind äußerst kompliziert und damit kostenintensiv aufgebaut.The solutions described in the prior art have only a limited protection in terms of jetting out of the can contents or they are extremely complicated and therefore expensive.
Es ist daher Aufgabe der Erfindung, die oben beschriebenen Nachteile des Standes der Technik zu beseitigen.It is therefore an object of the invention to eliminate the above-described disadvantages of the prior art.
Diese Aufgabe wird erfindungsgemäß durch einen Deckel nach Anspruch 1 gelöst. Das zumindest eine Schließelement ist als Rohrelement aus flexiblem Material ausgebildet, das mit der zumindest einen Druckausgleichsöffnung in Verbindung steht, wobei das Rohrelement über eine reversible Querschnittsverengung gas- und/oder flüssigkeitsdicht verschlossen ist, wenn sich das zumindest eine Betätigungselement in der Geschlossenposition befindet. Die Längsachse des Rohrelementes kann hierbei normal auf die Deckelspiegelebene oder aber im wesentlichen parallel zu ihr verlaufen. Getränkedosen und damit verbunden ihre Verschlusseinrichtungen müssen hohen Drücken im Doseninneren widerstehen. So entstehen bei der nach dem Befüllen und Verschließen der Getränkedose folgenden Pasteurisierung Drücke von 6 bar oder mehr, denen insbesondere auch die Druckausgleichseinrichtung standhalten muss. Eine ähnliche Situation besteht bei der Lagerung der Getränkedosen in einer heißen Umgebung bei 50°C und mehr (beispielsweise in einem in der Sonne stehenden Fahrzeug).This object is achieved by a lid according to claim 1. The at least one closing element is designed as a tubular element made of flexible material, which communicates with the at least one pressure equalization opening, wherein the tubular element is gas- and / or liquid-tightly closed by a reversible cross-sectional constriction when the at least one actuating element is in the closed position. The longitudinal axis of the tubular element can in this case be normal to the cover mirror plane or substantially parallel to it. Beverage cans and their associated closure devices must withstand high pressures inside the can. This results in the following after filling and closing the beverage can pasteurization pressures of 6 bar or more, which in particular the pressure compensation device must withstand. A similar situation exists when the beverage cans are stored in a hot environment at 50 ° C and more (for example, in a vehicle standing in the sun).
Bei dem erfindungsgemäßen Deckel ist besonders bevorzugt vorgesehen, dass das Rohrelement beim Bewegen des Betätigungselementes in die Geschlossenposition umgeknickt wird, wodurch ein Verschließen und Öffnen der Verschlusseinrichtung erleichtert wird. Durch das Umknicken des Rohrelementes wird ein hoher Verschlussdruck auf die Druckausgleichsöffnung ausgeübt, der insbesondere temporär oder permanent auftretenden hohen Innendrücken der Getränkedose widersteht. Gleichzeitig bleibt die Bauhöhe der Verschlusseinrichtung gering, weil die Elemente der erfindungsgemäßen Verschlusseinrichtung in ihren Dimensionen gering gehalten werden können. Insbesondere überragt sie den Bördelrand der Getränkedose nicht, was in der Getränkeindustrie aus fertigungstechnischen Gründen äußerst unerwünscht ist.In the case of the lid according to the invention, it is particularly preferred that the tube element is folded over when the actuating element is moved into the closed position, thereby facilitating closure and opening of the closure device. By the buckling of the tubular element, a high closure pressure is exerted on the pressure compensation opening, which in particular resists temporarily or permanently occurring high internal pressures of the beverage can. At the same time, the height of the closure device remains low, because the elements of the closure device according to the invention can be kept small in their dimensions. In particular, it does not exceed the beaded edge of the beverage can, which is extremely undesirable in the beverage industry for manufacturing reasons.
Erfindungsgemäß ist alternativ vorgesehen, dass das Rohrelement über ein Bedienelement, das mit dem Betätigungselement zusammenwirkt, verschließbar ist. Dieses Bedienelement stellt üblicherweise das Verbindungsglied zwischen dem Betätigungselement, das vom Benutzer zum Öffnen und Wiederverschließen insbesondere der Getränkedose bedient wird, und dem Verschlusselement, das die Ausgießöffnung in der Geschlossenposition gas- und flüssigkeitsdicht verschließt, dar. Hierbei ist vorzugsweise vorgesehen, dass das Bedienelement derart ausgeformt ist, dass es direkt oder indirekt auf das Rohrelement einwirkt.According to the invention, it is alternatively provided that the pipe element can be closed via an operating element which cooperates with the actuating element. This operating element usually represents the connecting element between the actuating element, which is operated by the user for opening and reclosing, in particular, the beverage can, and the closure element, which closes the pouring opening in the closed position in a gas- and liquid-tight manner. In this case, it is preferably provided that the operating element is such is formed that it acts directly or indirectly on the pipe element.
In einer besonders bevorzugten Ausführung der Erfindung weist das Bedienelement zumindest ein Umlenkelement auf, das in der Geschlossenposition des Betätigungselementes das Rohrelement verschließt. Das insbesondere aus zumindest geringfügig elastischem Material gefertigte Umlenkelement wirkt federnd oder starr auf das Rohrelement ein und verschließt es durch Querschnittsverengung bis hin zum Umknicken des Rohrelementes.In a particularly preferred embodiment of the invention, the operating element has at least one deflecting element, which closes the tubular element in the closed position of the actuating element. The deflection element, which is made in particular of at least slightly elastic material, acts resiliently or rigidly on the tubular element and closes it by narrowing the cross-section up to the buckling of the tubular element.
Ein besonders einfacher Aufbau der Verschlusseinrichtung wird erhalten, wenn das Betätigungselement und das Bedienelement einstückig, bevorzugterweise aus Kunststoff, gefertigt sind.A particularly simple construction of the closure device is obtained if the actuating element and the operating element are made in one piece, preferably made of plastic.
Alternativ hierzu steht das Bedienelement mit dem Betätigungselement in lösbarer Verbindung, was die Montage der Verschlusseinrichtung wesentlich erleichtert.Alternatively, the operating element with the actuating element in detachable connection, which facilitates the installation of the closure device substantially.
Eine besonders einfache zu öffnende und wiederverschließbare Verschlusseinrichtung mit geringer Bauhöhe insbesondere für Getränkedosen wird erhalten, wenn das zumindest eine Betätigungselement im Wesentlichen linear und parallel zu dem Deckel verschiebbar ist. Alternativ hierzu ist das zumindest eine Betätigungselement gegenüber dem Deckelspiegel verdrehbar.A particularly simple to open and recloseable closure device with low overall height, in particular for beverage cans is obtained when the at least one actuating element is substantially linear and parallel to the cover slidably. Alternatively, the at least one actuating element relative to the lid mirror is rotatable.
Zum Verschließen der Ausgießöffnung ist ein Verschlusselement vorgesehen, das besonders bevorzugt im Wesentlichen vertikal hinsichtlich des Deckels verschwenkbar ist. Hierbei ist insbesondere die Druckausgleichsöffnung in dem Betätigungselement angeordnet, wobei vorzugsweise die Druckausgleichsöffnung eine Dichtung aufweist, die mit einer umlaufenden Dichtung des Verschlusselementes in Verbindung steht. Die umlaufende Dichtung des Verschlusselementes hat die Aufgabe, ein Austreten von Flüssigkeit und/oder Gas, insbesondere Kohlensäure in der Geschlossenposition des Verschlusselementes zu verhindern.For closing the pouring opening, a closure element is provided, which is particularly preferably substantially vertically pivotable with respect to the lid. In this case, in particular, the pressure compensation opening is arranged in the actuating element, wherein preferably the pressure compensation opening has a seal which is in communication with a peripheral seal of the closure element. The peripheral seal of the closure element has the task of preventing leakage of liquid and / or gas, in particular carbonic acid in the closed position of the closure element.
Eine einfache Herstellung des Verschlusselementes wird möglich, wenn die Dichtung der Druckausgleichsöffnung mit der umlaufenden Dichtung des Verschlusselementes einstückig, insbesondere mittels eines geeigneten Zweikomponenten-Spritzgussverfahrens, gefertigt ist.A simple production of the closure element is possible when the seal of the pressure compensation opening with the peripheral seal of the closure element in one piece, in particular by means of a suitable two-component injection molding process is made.
Der erfindungsgemäße Deckel ist insbesondere für Behälter geeignet, deren Ausgießöffnung wiederverschließbar ist.The lid according to the invention is particularly suitable for containers whose pouring opening is resealable.
