ALCAN RORSCHACH AG Rorschach / SchweizALCAN RORSCHACH AG Rorschach / Switzerland
Die Erfindung betrifft einen Verschlußdeckel für Dosen oder dergleichen Behälter, bestehend aus einem Befestigungsring und einer dessen innere Ringöffnung membranartig überspannenden Verschlußfolie, wobei der Befestigungsring einen äußeren, zu seiner Befestigung am Korpus der Dose oder dergleichen ausgebildeten Bördeloder Falzrand sowie eine Auflagefläche für den Rand der Verschlußfolie hat, auf welche diese Verschlußfolie z.B. durch Ansiegeln abreißbar befestigt ist, und wobei an dem Rand der Verschlußfolie eine Abziehhilfe vorgesehen ist.The invention relates to a closure lid for cans or similar containers, consisting of a fastening ring and a sealing film spanning the inner ring opening like a membrane, wherein the fastening ring has an outer flanged or folded edge designed for its fastening to the body of the can or the like, as well as a support surface for the edge of the sealing film, to which this sealing film is attached in a tear-off manner, e.g. by sealing, and wherein a peel-off aid is provided on the edge of the sealing film.
Derartige Verschlußdeckel sind z.B. durch EP-O 090 957 A2, EP 0 357 276 Al und GB 21 66 409 A bekannt. Bei ihnen besteht die Abziehhilfen aus mit der Verschlußfolie einstückig ausgebildeten Abziehlaschen, mit welchen dieSuch closure lids are known, for example, from EP-O 090 957 A2, EP 0 357 276 Al and GB 21 66 409 A. In these cases, the removal aids consist of pull tabs formed in one piece with the closure film, with which the
Verschlußfolien zum Öffnen der Dose oder dergleichen von dem Befestigungsring abgezogen werden können. Zum besseren Erfassen durch den Benutzer sind diese Abziehlaschen geriffelt oder geprägt (EP 0 357 276 Al) oder mehrlagig (GB 2 166 409 A) ausgeführt.Sealing foils can be pulled off the fastening ring to open the can or similar. To make them easier for the user to grasp, these pull tabs are grooved or embossed (EP 0 357 276 Al) or multi-layered (GB 2 166 409 A).
Die bekannten Verschlußdeckel werden vielfach für Dosen oder dergleichen Behälter verwendet, deren Inhalt vakuumverpackt oder sterilisert werden soll. Zu diesem Zweck muß sowohl die Bördelbefestigung des Befestigungsringes des Verschlußdeckels am Behälterkörper als auch die Befestigung der Verschlußfolie auf dem Befestigungsring autoklavenfest sein. Bei einer derart festen Haftung der Verschlußfolie an dem Befestigungsring ist ein Abziehen der Verschlußfolie vom Befestigungsring auch bei Vorhandensein von geriffelten, geprägten oder mehrlagig ausgeführten Abziehlaschen schwierig.The known closure lids are often used for cans or similar containers whose contents are to be vacuum packed or sterilized. For this purpose, both the flange fastening of the fastening ring of the closure lid to the container body and the fastening of the closure film to the fastening ring must be autoclave-proof. With such a strong adhesion of the closure film to the fastening ring, it is difficult to remove the closure film from the fastening ring, even if there are grooved, embossed or multi-layered pull tabs.
Abhilfe brachte hier die Ausrüstung der am Rand der Verschlußfolie angeordneten Abziehlasche mit einer Greiföse (Pullring), die in der abstehenden Abziehlasche ausgebildet ist (DE-GM 85 19 750). Mit dieser Greiföse ist zwar ein sehr festes Erfassen und kräftiges Abziehen der Verschlußfolie möglich. Wegen der erforderlichen hohen Abziehkräfte (Peelkräfte) ist jedoch die Gefahr des Abreißens der relativ dünnen Abziehlasche von der Verschlußfolie gegeben.A solution to this problem was to equip the pull tab on the edge of the sealing film with a gripping eyelet (pull ring) that is formed in the protruding pull tab (DE-GM 85 19 750). This gripping eyelet allows the sealing film to be grasped very firmly and pulled off with force. However, due to the high peeling forces required, there is a risk of the relatively thin pull tab tearing off the sealing film.
Es sind außerdem folienartige Verschlußdeckel bekannt, an deren Oberseite ein Pullring angenietet ist, wie er von Getränkedosen bekannt ist (EP 0 117 125 Bl). Bei Deckeln aus oder mit Verschlußfolien, die vakuumdicht schließen sollen, ist jedoch die Anwendung eines solchen angenieteten Pullringes keine Lösung, da ein ausreichendesFilm-like closure lids are also known, to the top of which a pull ring is riveted, as is known from drinks cans (EP 0 117 125 Bl). However, for lids made of or with closure films that are intended to close vacuum-tight, the use of such a riveted pull ring is not a solution, since a sufficient
Abdichten der Nietstelle kaum möglich ist und darüber hinaus auch die Gefahr besteht, daß der Pullring mit dem Verbindungsniet aus dem dünnen Folienmaterial herausgerissen wird.Sealing the rivet point is hardly possible and there is also the risk that the pull ring with the connecting rivet will be torn out of the thin foil material.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Verschlußdeckel der eingangs genannten Gattung derart zu gestalten, daß sie die für eine autoklavenfeste Ansiegelung oder dergleichen Befestigung der Verschlußfolie am Befestigungsring notwendige hohe Zugkraft unbeschädigt aushält und ferner so ausgestaltet ist, daß die Abziehlasche vom Benutzer zum Abziehen so erfaßt werden kann, daß die dabei notwendige Zugkraft auch tatsächlich ausgeübt werden kann.The invention is therefore based on the object of designing a closure cap of the type mentioned at the outset in such a way that it can withstand the high tensile force required for an autoclave-proof seal or similar fastening of the closure film to the fastening ring without being damaged and is also designed in such a way that the pull tab can be grasped by the user for pulling off in such a way that the pulling force required can actually be exerted.
Diese Aufgabe wird erfindungsgemäß bei dem eingangs genannten Verschlußdeckel dadurch gelöst, daß der Greifring in einem von der Verschlußfolie getrennt ausgebildeten Lappen angeordnet ist, welcher Lappen an dem Rand der Verschlußfolie oder einer dort vorgesehenen und mit der Verschlußfolie einstückig ausgebildeten abstehenden Abziehlasche befestigt ist. Der den Ring aufweisende Lappen kann aus beliebigem Material, vorzugsweise Aluminium, bestehen und eine solche Dicke haben, daß er eine ausreichend große Zugfestigkeit besitzt. Dieser Lappen kann so an dem Rand der Verschlußfolie oder einem von dieser abstehenden Lasche angesiegelt sein, daß auch die Siegelbefestigung die Übertragung einer hohen Zugkraft ermöglicht.This object is achieved according to the invention in the closure lid mentioned at the beginning in that the gripping ring is arranged in a tab that is separate from the closure film, which tab is attached to the edge of the closure film or to a protruding pull tab provided there and formed as one piece with the closure film. The tab with the ring can be made of any material, preferably aluminum, and can be thick enough to have a sufficiently high tensile strength. This tab can be sealed to the edge of the closure film or to a tab that protrudes from it in such a way that the seal attachment also enables the transmission of a high tensile force.
Der Lappen des Greifringes kann dabei bis zur oder nahe an die Siegelverbindung der Verschlußfolie mit dem Befestigungsring des Verschlußdeckels heranreichen, wobei er möglichst über seine gesamte Breite angesiegelt werdenThe flap of the gripping ring can reach up to or close to the sealing connection between the sealing film and the fastening ring of the closure lid, whereby it should be sealed over its entire width if possible

sollte, um eine möglichst große Kraftübertragungsfläche zu gewährleisten. Die Festigkeit der Siegelverbindung des Greifringlappens mit der Verschlußfolie muß selbstverständlich größer sein als die Festigkeit der Siegelverbindung der Verschlußfolie mit dem Befestigungsring des Verschlußdeckels.should be used to ensure the largest possible force transmission area. The strength of the sealing connection between the grip ring flap and the sealing film must of course be greater than the strength of the sealing connection between the sealing film and the fastening ring of the closure lid.
Das Ansiegeln des den Greifring aufweisenden Lappens an die Verschlußfolie kann sowohl vor der eigentlichen Aufsiegelung der Folie auf dem Befestigungsring als auch nachher vorgenommen werden. Der Greifring kann von einem kreisförmigen Ausschnitt im Lappen gebildet und durch Umbördelung eines Randes des Ringes verstärkt sein.The flap with the grip ring can be sealed to the sealing film either before or after the actual sealing of the film onto the fastening ring. The grip ring can be formed by a circular cut-out in the flap and reinforced by flanging one edge of the ring.
In der Zeichnung ist ein besonders vorteilhaftes Ausführungsbeispiel des erfindungsgemäßen Verschlußdeckels und seiner Befestigung an einem Dosenkorpus dargestellt, die im folgenden näher beschrieben werden:The drawing shows a particularly advantageous embodiment of the closure lid according to the invention and its attachment to a can body, which are described in more detail below:

In Fig. 1 ist mit 1 der Korpus einer Dose oder dergleichen Behälter bezeichnet, der am Rand seiner Öffnung einen nach außen ragenden Kragen 2 hat, der zur Auflage eines Verschlußdeckels 3 aus Metallblech dient. Dieser Verschlußdeckel hat einen Befestigungsring 4, mit dem er auf dem Kragen 2 aufliegt, und einen äußeren Bördelrand 5, der mit dem Bördelrand 6 des Kragens 2 des Dosenkörpers verbördelt ist. Der Befestigungsring 4 hat radial innerhalb seines Bördelrandes 5 eine Auflagefläche für den Rand einer aus Aluminium bestehenden Verschlußfolie 7, die an dieser Auflagefläche angesiegelt ist und die vom Befestigungsring umgebene Ringöffnung membranartig überspannt. Diese Verschlußfolie 7 hat eine über ihren Rand an einer Stelle hinausragende Abziehlasche 8, die innerhalb des Bördelrandes 5 des Befestigungsringes 4 entlang einer Knicklinie 11 auf die Oberseite der Verschlußfolie zurückgefaltet ist. Auf die in zurückgefalteter Lage obenliegende Seite dieser Abziehlasche 8 ist ein Lappen 9 zum Beispiel aus Aluminium angesiegelt, der an seinem über die Abziehlasche 8 hinausragenden Ende mit einem Greifring 10 ausgebildet ist, der durch Umbördelung des inneren Ringrandes versteift ist.In Fig. 1, 1 designates the body of a can or similar container, which has an outwardly projecting collar 2 on the edge of its opening, which serves to support a closure lid 3 made of sheet metal. This closure lid has a fastening ring 4, with which it rests on the collar 2, and an outer flanged edge 5, which is flanged to the flanged edge 6 of the collar 2 of the can body. The fastening ring 4 has a bearing surface radially inside its flanged edge 5 for the edge of a sealing film 7 made of aluminum, which is sealed to this bearing surface and spans the ring opening surrounded by the fastening ring like a membrane. This sealing film 7 has a pull-off tab 8 which protrudes beyond its edge at one point and which is folded back onto the top of the sealing film inside the flanged edge 5 of the fastening ring 4 along a fold line 11. A flap 9, made of aluminum for example, is sealed onto the upper side of this pull tab 8 in the folded-back position, which flap is formed at its end protruding beyond the pull tab 8 with a gripping ring 10 which is stiffened by flanging the inner ring edge.
Der Lappen 9 und der an ihm ausgebildete Greifring 10 sowie die Siegelverbindung des Lappens 9 mit der Abziehlasche 8 der Verschlußfolie 7 müssen solche Zugfestigkeit haben, daß die insbesondere bei einer autoklavenfesten Ansiegelung der Folie 7 an dem Befestigungsring 4 des Verschlußdeckels 3 erforderliche hohe Zugkraft von dem Greifring 10 auf die Folie 7The flap 9 and the gripping ring 10 formed on it, as well as the sealing connection of the flap 9 with the pull tab 8 of the sealing film 7 must have such a tensile strength that the high tensile force required, particularly for an autoclave-proof sealing of the film 7 to the fastening ring 4 of the sealing lid 3, is exerted by the gripping ring 10 on the film 7.
übertragen werden kann, ohne dabei eine Beschädigung der Aufreißhilfe befürchten zu müssen.can be transferred without having to fear damaging the tear aid.
Die Erfindung kann bei jeder an einen Behälterrand oder einen Deckelring angesiegelten Verschlußfolie angewendet werden.The invention can be applied to any sealing film sealed to a container rim or a lid ring.
