Description

Die vorliegende Erfindung betrifft einen metallischen Dosendeckel mit einer wiederverschließbaren Öffnung, insbesondere für Getränkedosen sowie für Behältnisse zur Aufbewahrung von Lebensmitteln und sonstigen flüssigen, pastösen, pulverförmigen und/oder festen Produkten.The present invention relates to a metallic can lid with a resealable opening, in particular for beverage cans and for containers for storing food and other liquid, pasty, powdery and / or solid products.

Aus der EP 1 607 341 A1 ist ein Dosendeckel mit einer wiederverschließbaren Öffnung bekannt, bei dem in dem metallischen Dosendeckel eine Öffnung eingebracht und der Rand dieser Öffnung umgebördelt ist, um eine Verankerungsmöglichkeit für ein vorgefertigtes Kunststoff-Verschlussteil zu schaffen. Das Kunststoff-Verschlussteil umfasst ein mit dem Bördelrand der Dosenöffnung zu verbindendes Basisteil, in dem eine durch einen Flachstopfen verschlossene Öffnung ausgebildet ist. Der Flachstopfen ist mit dem Öffnungsrand über eine Kunststoff-Reißnaht verbunden, so dass der mit einer Aufreißlasche verbundene Flachstopfen durch Zugausübung über die Aufreißlasche von dem Kunststoff-Basisteil gelöst und in eine Öffnungsstelle verschwenkt werden kann. Die Öffnung kann durch Eindrücken des an seiner Unterseite vorzugsweise konisch ausgebildeten Flachstopfens wieder vorübergehend verschlossen werden.From the EP 1 607 341 A1 a can lid with a resealable opening is known in which an opening is made in the metallic can lid and the edge of this opening is flanged in order to create an anchoring option for a prefabricated plastic closure part. The plastic closure part comprises a base part which is to be connected to the flanged edge of the can opening and in which an opening closed by a flat stopper is formed. The flat stopper is connected to the opening edge via a plastic tear seam, so that the flat stopper connected to a pull tab can be detached from the plastic base part by pulling over the pull tab and pivoted into an opening point. The opening can be temporarily closed again by pressing in the flat plug, which is preferably conical on its underside.

Wiederverschließbare Dosendeckel sind ferner beispielsweise in der DE 10 2010 013 531 A1 , der DE 10 2015 112 428 A1 und der EP 2 354 022 B1 beschrieben.Resealable can lids are also for example in the DE 10 2010 013 531 A1 , the DE 10 2015 112 428 A1 and the EP 2 354 022 B1 described.

Aufgabe der Erfindung ist es, einen wiederverschließbaren Dosendeckel anzugeben, der besonders günstig in der Herstellung ist und dennoch einerseits leicht zu betätigen ist und andererseits gute Dichteigenschaften aufweist.The object of the invention is to provide a resealable can lid which is particularly inexpensive to manufacture and yet on the one hand easy to operate and on the other hand has good sealing properties.

Diese Aufgabe wird gelöst durch einen metallischen Dosendeckel mit den Merkmalen des Anspruchs 1.This object is achieved by a metallic can lid with the features of claim 1.

Ein Mikrospalt gewährleistet ein besonders einfaches Öffnen des Dosendeckels, aber auch eine Schwächungslinie ist grundsätzlich geeignet. Über die Dicht- und Rastrippen sowie die zugehörigen Aufnahmenuten kann ein wirksamer Verschluss und Wiederverschluss erreicht werden. Hierbei ist es besonders vorteilhaft, dass der Dichtungsrahmen mit der festen Deckelfläche und die Verschließeinheit mit dem hochschwenkbaren metallischen Deckelbereich stoffschlüssig verbunden sind.A micro gap ensures that the can lid can be opened particularly easily, but a line of weakness is also generally suitable. An effective closure and reclosure can be achieved via the sealing and locking ribs and the associated receiving grooves. It is particularly advantageous here that the sealing frame is firmly connected to the fixed cover surface and the closing unit to the metal cover area that can be pivoted up.

Erfindungsgemäß bilden die Dicht- und Rastrippen mit den Aufnahmenuten mindestens zwei, bevorzugt drei Dichtkanten, wobei die Dichtkanten so ausgebildet sind, dass beim Öffnen des Dosendeckels die radial innerste Dichtkante noch dichtet, wenn die radial äußere oder beide radial äußeren Dichtkanten gerade gelöst sind. Auf diese Weise kann ein sogenanntes Venting einer mit dem Dosendeckel verschlossenen Dose erreicht werden, das heißt, ein langsamer Druckabbau vor dem vollständigen Öffnen des Dosendeckels.According to the invention, the sealing and locking ribs with the receiving grooves form at least two, preferably three sealing edges, the sealing edges being designed so that when the can lid is opened, the radially innermost sealing edge still seals when the radially outer or both radially outer sealing edges are just released. In this way, so-called venting of a can closed with the can lid can be achieved, that is, a slow pressure reduction before the can lid is completely opened.

Nach einer bevorzugten Ausgestaltung der Erfindung weist die radial innerste Dichtkante einen größeren Abstand zur Deckelfläche auf als die andere oder die beiden anderen Dichtkanten. Dadurch löst die innerste Dichtkante nach der oder den beiden anderen Dichtkanten, so dass das genannte Venting erreicht wird.According to a preferred embodiment of the invention, the radially innermost sealing edge has a greater distance from the cover surface than the other or the two other sealing edges. As a result, the innermost sealing edge detaches after the other sealing edge or two, so that said venting is achieved.

Nach einer besonders bevorzugten Ausgestaltung der Erfindung verläuft zumindest die radial innerste Dichtkante in einer Ebene, die gegenüber der Ebene des innerhalb des Mikrospalts oder der Schwächungslinie gelegenen Deckelbereichs geneigt ist, wobei die beiden Ebenen auf der dem Schwenklager abgewandten Seite den größten Abstand voneinander aufweisen. Durch diese Ausgestaltung kann erreicht werden, dass die innerste Dichtkante über ihren gesamten Umfang so lange dichtet, bis die äußere oder die beiden äußeren Dichtkanten gelöst sind.According to a particularly preferred embodiment of the invention, at least the radially innermost sealing edge runs in a plane that is opposite to the plane of the is inclined inside the microgap or the weakening line lid area, the two planes on the side facing away from the pivot bearing have the greatest distance from each other. This configuration can ensure that the innermost sealing edge seals over its entire circumference until the outer or both outer sealing edges are released.

Nach einer weiteren Ausgestaltung der Erfindung, die auch für sich beansprucht wird, sind die Dicht- und Rastrippen einerseits und die Aufnahmenuten andererseits so ausgebildet, dass sie sich bei aufwölbendem Dosendeckel zunehmend miteinander verhaken. Hierdurch kann gewährleistet werden, dass der Dosendeckel auch bei steigendem Innendruck in der Dose geschlossen bleibt.According to a further embodiment of the invention, which is also claimed for itself, the sealing and locking ribs on the one hand and the receiving grooves on the other hand are designed in such a way that they increasingly interlock with one another when the can lid bulges. This ensures that the can lid remains closed even when the internal pressure in the can increases.

Nach einer bevorzugten Ausgestaltung dieses Erfindungsgedankens weist eine am Dichtungsrahmen vorgesehene Rastrippe einen nach außen weisenden Haken auf, der mit einem entsprechend nach innen weisenden Rastvorsprung einer Aufnahme der Verschließeinheit zusammenwirkt. Durch diese Ausgestaltung wird eine zunehmende Verhakung bei sich aufwölbendem Dosendeckel erreicht.According to a preferred embodiment of this inventive concept, a locking rib provided on the sealing frame has an outwardly pointing hook which cooperates with a correspondingly inwardly pointing locking projection of a receptacle of the closing unit. This configuration results in increasing entanglement in the case of the can lid bulging.

Nach noch einer Ausgestaltung der Erfindung, die ebenfalls auch für sich beansprucht wird, weist das Aufreißorgan eine Durchbrechung auf, in welche ein Fortsatz der Verschließeinheit eingreift, wobei der Fortsatz derart fest, insbesondere stoffschlüssig, mit dem Aufreißorgan verbunden ist, dass der Fortsatz beim Hochschwenken des Aufreißorgans von der Verschließeinheit abgerissen wird. Durch diese Ausgestaltung wird ein Originalitätsverschluss geschaffen, also ein Verschluss, dessen Öffnen irreversibel erkennbar wird.According to another embodiment of the invention, which is also claimed for itself, the tear-open member has an opening in which an extension of the locking unit engages, the extension being firmly, in particular cohesively, connected to the tear-open member that the extension is swiveled up of the ripping member is torn off from the sealing unit. This configuration creates a tamper-evident closure, that is to say a closure whose opening is irreversibly recognizable.

Nach einer besonders bevorzugten Weiterbildung dieses Erfindungsgedankens sind die Durchbrechung und der Fortsatz im Bereich des Schwenklagers des Aufreißteils vorgesehen. Hierdurch wird erreicht, dass das Abreißen des Fortsatzes bereits beim Anheben des Aufreißteils erfolgt, so dass jede Manipulation des Dosendeckels verhindert werden kann.According to a particularly preferred further development of this inventive concept, the opening and the extension are provided in the area of the pivot bearing of the tear-open part. This ensures that the extension is torn off takes place when the tear-open part is raised, so that any manipulation of the can lid can be prevented.

Der in den Figuren dargestellte Dosendeckel 1 besteht aus Metall, insbesondere Aluminium, und weist eine wiederverschließbare Öffnung auf. Dafür ist im Deckel neben einer festen Deckelfläche 2 ein hochschwenkbarer Deckelbereich 3 vorgesehen. Der hochschwenkbare Deckelbereich 3 ist von dem festen Deckelbereich 2 durch einen umlaufenden Mikrospalt 4 oder eine Schwächungslinie getrennt (siehe insbesondere Fig. 6).The can lid 1 shown in the figures consists of metal, in particular aluminum, and has a resealable opening. For this purpose, a lid area 3 that can be pivoted up is provided in the lid in addition to a fixed lid surface 2. The pivotable lid area 3 is separated from the fixed lid area 2 by a circumferential microgap 4 or a line of weakness (see in particular Fig. 6 ).

Mit der festen Deckelfläche 2 ist ein den Öffnungsbereich umschließender Dichtungsrahmen 5 aus Kunststoffmaterial verbunden, und zwar insbesondere durch ein sogenanntes Hot-Melt-Verfahren unter Verwendung eines Haftvermittlers, um eine feste Verbindung mit dem Aluminium des Deckels zu gewährleisten. Mit dem hochschwenkbaren metallischen Deckelbereich 3 ist des Weiteren eine Verschließeinheit 6 verbunden, die ebenfalls aus Kunststoff besteht und über ein Schwenklager 7 schwenkbar an der festen Deckelfläche 2 angebracht ist. Das Schwenklager 7 und die Verschließeinheit 6 sind wiederum insbesondere über eine Hot-Melt-Verbindung unter Verwendung eines Haftvermittlers mit der festen Deckelfläche 2 bzw. dem hochschwenkbaren Deckelbereich 3 verbunden.A sealing frame 5 made of plastic material surrounding the opening area is connected to the fixed cover surface 2, in particular by a so-called hot-melt process using an adhesion promoter, in order to ensure a firm connection with the aluminum of the cover. A closing unit 6, which is also made of plastic and is pivotably attached to the fixed cover surface 2 via a pivot bearing 7, is also connected to the metal cover area 3 which can be swiveled up. The pivot bearing 7 and the closing unit 6 are in turn connected to the fixed cover surface 2 or the cover area 3 which can be pivoted up, in particular via a hot-melt connection using an adhesion promoter.

An der dem Schwenklager 7 diametral gegenüberliegenden Seite ist die Verschließeinheit mit einem hochschwenkbaren Aufreißorgan 8 verbunden, welches im nicht hochgeschwenkten Zustand parallel zur Deckeloberseite 9 angeordnet ist. Das Aufreißorgan 8 ist in bekannter Weise ringförmig ausgebildet und durch Eingriffnahme mit einem Finger in ein Eingriffende 10 gegenüber der Deckelfläche um ein Schwenklager 11 hochschwenkbar.On the side diametrically opposite the pivot bearing 7, the closing unit is connected to a pivotable tear-open member 8 which, when not pivoted up, is arranged parallel to the top 9 of the lid. The tear-open member 8 is designed in a known manner in the shape of a ring and, by engaging a finger in an engaging end 10, can be pivoted upward about a pivot bearing 11 relative to the cover surface.

Der Dichtungsrahmen 5 und die Verschließeinheit 6 wirken über Dicht- und Rastrippen 12, 13, 14 am Dichtungsrahmen 5 und zugehörige Aufnahmenuten 15, 16, 17 an der Verschließeinheit 6 dichtend zusammen. Dadurch werden drei Dichtkanten 18, 19, 20 gebildet, durch welche der Öffnungsbereich des Dosendeckels abgedichtet ist. Auch bei Verwendung eines Mikrospalts 4 zwischen dem hochschwenkbaren Deckelbereich 3 und dem festen Deckelbereich 2 ist dadurch eine Dichtigkeit des Dosendeckels gewährleistet.The sealing frame 5 and the closing unit 6 work together in a sealing manner via sealing and locking ribs 12, 13, 14 on the sealing frame 5 and associated receiving grooves 15, 16, 17 on the closing unit 6. As a result, three sealing edges 18, 19, 20 are formed, through which the opening area of the can lid is sealed. Even when using a micro gap 4 between the pivotable Lid area 3 and the fixed lid area 2 thereby ensure that the can lid is sealed.

Wie man insbesondere in Fig. 6 sehen kann, ist die radial innerste Dichtkante 18 weiter von der Deckelfläche entfernt als die beiden anderen Dichtkanten 19 und 20. Die innerste Dichtkante 18 dichtet daher noch ab, wenn die beiden äußeren Dichtkanten 19 und 20 beim Öffnen des Dosendeckels bereits gerade gelöst sind. Auf diese Weise kann ein sogenanntes Venting des Doseninneren erfolgen, also ein langsamer Druckabbau vor dem vollständigen Öffnen.How to particularly work in Fig. 6 can see, the radially innermost sealing edge 18 is further away from the lid surface than the other two sealing edges 19 and 20. The innermost sealing edge 18 therefore still seals when the two outer sealing edges 19 and 20 are already released when the can lid is opened. In this way, so-called venting of the inside of the can can take place, i.e. a slow pressure reduction before complete opening.

Wie man insbesondere in den Fig. 9 und 10 sehen kann, verläuft die radial innerste Dichtkante 18 in einer Ebene I, die gegenüber der Deckelebene II geneigt ist. Die Neigung beträgt dabei beispielsweise 1 bis 2°, insbesondere 1,5°. Hierdurch ist gewährleistet, dass die innerste Dichtkante 18 beim Hochschwenken des Deckelbereichs 3 über ihren gesamten Umfang noch abdichtet, wenn sich die beiden äußeren Dichtkanten 19, 20 gerade gelöst haben. Beim Venting des Doseninneren kann hierdurch verhindert werden, dass Flüssigkeit aus dem Doseninneren nach außen gelangt.How to get in particular in the Figures 9 and 10 can see, the radially innermost sealing edge 18 runs in a plane I, which is inclined with respect to the cover plane II. The inclination is, for example, 1 to 2 °, in particular 1.5 °. This ensures that the innermost sealing edge 18 still seals over its entire circumference when the cover region 3 is pivoted up, when the two outer sealing edges 19, 20 have just loosened. When venting the inside of the can, this can prevent liquid from escaping from the inside of the can.

Wie man insbesondere in den Fig. 5 und 6 erkennen kann, weist die am Dichtungsrahmen 5 vorgesehene radial äußerste Dicht- und Rastrippe 12 einen nach außen weisenden Haken 21 auf, der mit einem entsprechend nach innen weisenden Rastvorsprung 22 der zugehörigen Aufnahme 15 der Verschließeinheit 6 zusammenwirkt. Hierdurch wird erreicht, dass sich die Dicht- und Rastrippe 12 mit der Aufnahme 15 bzw. deren Rastvorsprung zunehmend verhakt, wenn sich der Dosendeckel aufwölbt, beispielsweise durch steigenden Innendruck in der Dose.How to get in particular in the Figures 5 and 6 The radially outermost sealing and locking rib 12 provided on the sealing frame 5 has an outwardly pointing hook 21 which interacts with a correspondingly inwardly pointing locking projection 22 of the associated receptacle 15 of the closing unit 6. What is achieved hereby is that the sealing and locking rib 12 increasingly interlocks with the receptacle 15 or its locking projection when the can lid bulges, for example due to increasing internal pressure in the can.

Wie man insbesondere in den Fig. 2 und 6 sehen kann, weist das Aufreißorgan 8 eine Durchbrechung 23 auf, in welche ein Fortsatz 24 der Verschließeinheit 6 eingreift. Der Fortsatz 24 ist derart fest, insbesondere stoffschlüssig, mit dem Aufreißorgan 8 verbunden, dass der Fortsatz 24 beim Hochschwenken des Aufreißorgans 8 von der Verschließeinheit 6 abgerissen wird. Eine solche feste Verbindung kann beispielsweise dadurch erreicht werden, dass der Fortsatz 24 nach dem Spritzgießen dieses Kunststoffteils derart angeschmolzen wird, dass es sich mit dem die Durchbrechung 23 bildenden Teil des Aufreißorgans 8 fest verbindet. Dies kann beispielsweise durch eine Art Lötkolben bewirkt werden.How to get in particular in the Fig. 2 and 6 can see, the tear-open member 8 has an opening 23 into which an extension 24 of the closing unit 6 engages. The extension 24 is so firmly, in particular cohesively, with the tear-open element 8 connected that the extension 24 is torn off from the closing unit 6 when the ripping member 8 is pivoted upward. Such a fixed connection can be achieved, for example, in that the extension 24 is melted after the injection molding of this plastic part in such a way that it is firmly connected to the part of the tear-open element 8 that forms the opening 23. This can be achieved, for example, by a kind of soldering iron.

Wie man in Fig. 6 erkennt, sind die Durchbrechung 23 und der Fortsatz 24 im Bereich des Schwenklagers 11 des Aufreißorgans 8 vorgesehen. Dadurch wird erreicht, dass bereits ein geringes Anheben des Aufreißorgans 8 genügt, um den Fortsatz 24 abzureißen.How to get in Fig. 6 recognizes, the opening 23 and the extension 24 are provided in the area of the pivot bearing 11 of the tear-open member 8. This means that even a slight lifting of the tear-open member 8 is sufficient to tear off the extension 24.

Beim dargestellten Ausführungsbeispiel ist die Innenseite des Dosendeckels mit einer Kunststofffolie 25 laminiert, welche die gesamte Deckelinnenseite abdeckt. Abweichend hiervon kann die Kunststofffolie auch ringförmig ausgebildet sein und nur um wenige Zehntel Millimeter, insbesondere 3 bis 4 Zehntel Millimeter, beidseits über den Mikrospalt 4 oder die Schwächungslinie hinaus reichen. Eine andere Möglichkeit besteht darin, eine scheibenförmige Dichtungsfolie zu verwenden, die um wenige Zehntel Millimeter, beispielsweise 3 bis 4 Zehntel Millimeter radial nach außen über den Mikrospalt 4 bzw. die Schwächungslinie hinaus reicht. Die Dichtungsfolie kann in diesem Fall als weitgehend flache Scheibe ausgebildet sein. Sowohl die ringförmige als auch die scheibenförmige Dichtungsfolie sind bevorzugt als Stanzteil ausgebildet.In the embodiment shown, the inside of the can lid is laminated with a plastic film 25 which covers the entire inside of the lid. Notwithstanding this, the plastic film can also be designed in the shape of a ring and only extend by a few tenths of a millimeter, in particular 3 to 4 tenths of a millimeter, on both sides beyond the microgap 4 or the line of weakness. Another possibility is to use a disk-shaped sealing film which extends by a few tenths of a millimeter, for example 3 to 4 tenths of a millimeter, radially outward beyond the microgap 4 or the line of weakness. In this case, the sealing film can be designed as a largely flat disk. Both the ring-shaped and the disk-shaped sealing film are preferably designed as a stamped part.

Während auf der Außenseite des Dosendeckels 1 stets der Dichtungsrahmen 5 und die Verschließeinheit 6 angebracht und über einen Haftvermittler mit dem Dosendeckel verbunden sind, kann die Deckelinnenseite abweichend von dem Ausführungsbeispiel auch zumindest weitgehend frei von Laminierungen und dergleichen sein. Die Deckelinnenseite kann aber mit einer insbesondere lebensmitteltauglichen Lackschicht versehen sein, um einen Kontakt des in der Dose befindlichen Gutes mit dem metallischen Deckelmaterial zu verhindern.While the sealing frame 5 and the closing unit 6 are always attached to the outside of the can lid 1 and connected to the can lid via an adhesion promoter, the inside of the lid can, in contrast to the exemplary embodiment, also be at least largely free of laminations and the like. The inside of the lid can, however, be equipped with an in particular food grade Be provided with a layer of lacquer to prevent the goods in the can from coming into contact with the metallic lid material.

Wie man insbesondere in den Fig. 5 und 6 erkennen kann, übergreift die stoffschlüssig mit dem festen Deckelbereich 2 verbundene Verschließeinheit 6 den Mikrospalt 4. Auf diese Weise kann auch ohne deckelinnenseitige Dichtungsfolie eine Dichtheit des Dosendeckels gewährleistet werden.How to get in particular in the Figures 5 and 6 can see, the sealing unit 6, which is firmly connected to the fixed lid area 2, overlaps the microgap 4. In this way, a tightness of the can lid can be ensured even without a sealing film on the inside of the lid.
