Ein derartiger Aufsatz eignet sich vorzüglich zum Aufsetzen auf handelsübliche allseitig verschlossene Getränkedosen da er einfach und billig in der Herstellung ist, mit nur wenigen Handgriffen und unter geringem Kraftaufwand ein Öffnen der Dose ermöglicht und auch bei verschmutzten Oberflächen der Getränkedose einen hygienisch einwandfreien Genuß des in dem Hohlbehälter enthaltenen Getränks ermöglicht.Such an attachment is particularly suitable for placing on commercially available beverage cans which are closed on all sides, since it is simple and inexpensive to manufacture, allows the can to be opened with just a few hand movements and with little effort, and also on soiled surfaces the beverage can enables a hygienically perfect enjoyment of the beverage contained in the hollow container.

Ein weiterer Aufsatz insbesondere für oben offene Getränkedosen und Pappbecher ist im DE-GBM 295 04 615 des Anmelders beschrieben, wobei dieser ebenfalls aus einem Innendeckel mit einer unter einem Winkel des Deckelebene ansteigenden Erhöhung und aus einem auf einem Teil des Innendeckels aufliegendem Außendeckel besteht, der auf seiner Unterseite und oberhalb der im Innendeckel vorgesehenen Öffnung einen nach unten gerichteten Öffnungsdorn aufweist, wobei der Öffnungsdorn von einer konzentrischen Kappe umgeben ist, deren oberes Ende mit dem Innendeckel fest verbunden ist.Another article, in particular for beverage cans and paper cups open at the top, is described in the applicant's DE-GBM 295 04 615, which also consists of an inner lid with an increase rising at an angle of the lid level and an outer lid resting on part of the inner lid has a downward opening mandrel on its underside and above the opening provided in the inner cover, the opening mandrel being surrounded by a concentric cap, the upper end of which is firmly connected to the inner cover.

Mit diesem Aufsatz lassen sich vorzüglich Getränkedosen, Pappbecher und dgl., die nicht durch einen oberen Metalldeckel verschlossen sind, hygienisch einwandfrei und luftdicht verschließen, bei gleichzeitig hygienisch bedenkenlosem Genuß des im Hohlbehälter enthaltenen Lebensmittels, beispielsweise eines Getränks.With this attachment, beverage cans, paper cups and the like, which are not closed by an upper metal lid, can be sealed hygienically and airtight, while at the same time hygienically safe enjoyment of the food contained in the hollow container, for example a drink.

Aufgabe der vorliegenden Neuerung ist es, einen Verschluß für oben offene Hohlbehälter, insbesondere Dosen aller Art und Pappbecher zu schaffen, der noch einfacher im Aufbau ist und bei dem auch nach einer längeren Lagerzeit, d.h. einer Zeit von mehr als 8 Monaten die Qualität des im Hohlbehälter aufbewahrten Lebensmittels, beispielsweise eines alkoholfreien Getränks durch äußere Einflüsse nicht beeinträchtigt wird.The object of the present innovation is to provide a closure for hollow containers open at the top, in particular cans of all types and paper cups, which is even simpler in construction and in which the quality of the product, even after a longer storage period, ie a period of more than 8 months Hollow container of stored food, for example one non-alcoholic drink is not affected by external influences.

Ausgehend von dem im Oberbegriff des Anspruches 1 näher ausgeführten Verschluß erfolgt die Lösung dieser Aufgabe mit den im kennzeichnenden Teil angegebenen Merkmalen; vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.Starting from the closure detailed in the preamble of claim 1, this object is achieved with the features specified in the characterizing part; advantageous embodiments are described in the subclaims.

Der neuerungsgemäße Verschluß ist einfach im Aufbau, billig in der Herstellung und bewirkt einen absolut gasdichten bzw. flüssigkeitsdichten Verschluß eines damit versehenen Hohlbehälters über einen langen Zeitraum hinweg. Die vorgesehene Dampfdiffusionssperre sorgt dafür, daß keinerlei äußere Einflüsse die Qualität des im Hohlbehälters enthaltenen Lebensmittels beeinträchtigen; sie ermöglicht, einen Überdruck oder Unterdruck im Behälter aufrechtzuerhalten, so daß das enthaltene Lebensmittel im Behälter bis zur Öffnung frisch bleibt; nach dem Öffnen zum Genuß des Lebensmittels erfolgt ein zeitweiliger Verschluß, der über einen Zeitraum von mehreren Tagen hinweg das angebrochene Lebensmittel genußfähig hält.The closure according to the invention is simple in construction, cheap to manufacture and brings about an absolutely gas-tight or liquid-tight closure of a hollow container provided with it over a long period of time. The vapor diffusion barrier provided ensures that no external influences impair the quality of the food contained in the hollow container; it makes it possible to maintain an overpressure or underpressure in the container, so that the food contained in the container remains fresh until opened; after opening to enjoy the food, there is a temporary closure which keeps the opened food edible for a period of several days.

Im folgenden wird die Neuerung anhand der Zeichnung näher erläutert, in der ein vorteilhaftes Ausführungsbeispiel dargestellt ist. Es zeigen:

a partial section through the closure according to the innovation with the essential parts and
Fig. 2
a variant of the connection between the closure and the hollow container.

In den Figuren ist mit 1 die senkrechte Außenwand eines oben offenen Hohlbehälters, beispielsweise einer handelsüblichen Getränkedose bezeichnet, deren oberer Rand 2 nach außen ein- oder zweifach geschlungen sein kann (Figur 1) oder aber nach innen abgebogen sein kann (Figur 2). Der neuerungsgemäße Verschluß besteht nun aus einem Innendeckel 3, der im wesentlichen die gesamte Oberfläche der kreisförmigen Getränkedose 1 abdeckt und der entlang seiner Randes mit einem umlaufenden Ringflansch 7 versehen ist, dessen oberes Ende 4 gemäß Figur 1 an das Oberteil 2 der Getränkedose angepaßt ist, wobei das Ende 4 mit dem Ringflansch 7 fest verfalzt und/oder verklebt und/oder thermoplastisch verschweißt ist. Statt dessen kann die Verbindung auch durch ein aufgespresstes, umlaufendes Klemmteil 5 erfolgen, welches den Flansch 7 mit dem oberen Ende des Randes 2 der Dose 1 verbindet. Bei dem in Figur 2 dargestellten Ausführungsbeispiel ist der obere Rand 6 der Dose 1 nach innen gewölbt und das obere Ende 8 des Ringflansches 7 sitzt als Schnappverschluß in der durch den Rand 6 gebildeten Wölbung.In the figures, 1 denotes the vertical outer wall of a hollow container open at the top, for example a commercially available beverage can, the upper edge 2 of which can be looped out once or twice (Figure 1) or can be bent inwards (Figure 2). The closure according to the invention now consists of an inner lid 3 which covers essentially the entire surface of the circular beverage can 1 and which is provided along its edge with a circumferential ring flange 7, the upper end 4 of which is adapted to the upper part 2 of the beverage can according to FIG. 1, the end 4 being firmly crimped and / or glued and / or thermoplastic welded to the ring flange 7. Instead, the connection can also be made by a pressed-on, circumferential clamping part 5, which connects the flange 7 to the upper end of the edge 2 of the box 1. In the exemplary embodiment shown in FIG. 2, the upper edge 6 of the can 1 is curved inwards and the upper end 8 of the ring flange 7 sits as a snap lock in the curvature formed by the edge 6.

Der Innendeckel 3 ist, wie es links in der Figur 1 angedeutet ist, mit einer unter einem Winkel ansteigenden Erhöhung 18 versehen, die sich über einen Teil seines Außenrandes erstreckt und die als Trinklippe nach dem Öffnen des Verschlusses dient. Der Innendeckel 3 ist ferner mit einer Öffnung 11 versehen, die dazu dient, nach Verschwenken des Außendeckels 9 um eine im Innendeckel vorgesehene Gelenkachse 20 das in der Dose 1 enthaltene Getränk zu entleeren.The inner lid 3 is, as indicated on the left in FIG. 1, provided with an elevation 18 rising at an angle, which extends over part of its outer edge and which serves as a drinking lip after the closure has been opened. The inner lid 3 is also provided with an opening 11, which serves to empty the beverage contained in the can 1 after pivoting the outer lid 9 about a hinge axis 20 provided in the inner lid.

Der Außendeckel 9 ist mit einem im wesentlichen die gesamte Öffnung 11 ausfüllenden Vorsprung 10 versehen, dessen Unterseite mit der Unterseite des Innendeckels 3 im wesentlichen fluchtet.The outer cover 9 is provided with a projection 10 substantially filling the entire opening 11, the underside of which is essentially flush with the underside of the inner cover 3.

Die Öffnung 11 im Innendeckel 3 ist ferner in ihrem unteren Bereich mit einer umlaufenden ersten Nut 12 versehen, in welche ein angepaßter, den unteren Bereich des Vorsprungs 10 umgebende Wulst 14 eingreift; eine zweite parallel zur ersten Nut 12 umlaufende Nut 15 kann in der Wand der Öffnung 11 oberhalb der Nut 12 vorgesehen sein, wobei in diesem Fall ein zweiter parallel zum ersten Wulst 14 verlaufender Wulst 13 entlang des Außenrandes des Vorsprungs 10 vorgesehen ist. Durch diese Ausgestaltung wird der Vorsprung 10 im Klemmsitz in der Öffnung 11 im Innendeckel 3 gehalten.The opening 11 in the inner cover 3 is further provided in its lower region with a circumferential first groove 12, in which an adapted bead 14, which surrounds the lower region of the projection 10, engages; a second groove 15 running parallel to the first groove 12 can be provided in the wall of the opening 11 above the groove 12, in which case a second bead 13 running parallel to the first bead 14 is provided along the outer edge of the projection 10. With this configuration, the projection 10 is held in the clamp fit in the opening 11 in the inner cover 3.

Die gesamte Unterseite des Innendeckels 3 einschließlich des Bereichs der Öffnung 11 und damit auch die Unterseite des Vorsprungs 10 sind nun mit einer Dampfdiffusionssperre 16 versehen, welche fest mit dem Ringflansch 7 des Verschlusses verbunden ist und damit mit dem oberen Rand des Hohlbehälters, d.h. der Dose oder des Pappbechers 1. Diese Dampfdiffusionssperre aus einem geeigneten Material, beispielsweise Metall oder einem Kunststoff, dient dazu, das in dem Hohlbehälter 1 enthaltene Lebensmittel über einen langen Zeitraum frisch zu halten. Im Bereich der Öffnung 11 und damit des in die Öffnung 11 eingesetzten Vorsprungs 10 ist die Dampfdiffusionssperre 16 mit einer an den Umfang der Öffnung angepaßten, vorzugsweise kreisförmigen Aufreißperforation 19 versehen. Da die Dampfdiffusionssperre fest sowohl mit dem Innendeckel als auch dem Vorsprung des Außendeckels verbunden ist, kann die Perforation dadurch aufgetrennt werden, daß entweder durch Druck auf den Außendeckel 9 der Vorsprung 10 in das Innere des Kohlbehälters 1 eingedrückt wird oder aber durch Verschwenken des Außendeckels 9 um die Gelenkachse 20 der Vorsprung 10 den an ihm haftenden Teil der Dampfdiffusionssperre nach oben entfernt.The entire underside of the inner cover 3 including the area of the opening 11 and thus also the underside of the projection 10 are now provided with a vapor diffusion barrier 16 which is firmly connected to the ring flange 7 of the closure and thus to the upper edge of the hollow container, ie the can or the paper cup 1. This vapor diffusion barrier made of a suitable material, for example metal or a plastic serves to keep the food contained in the hollow container 1 fresh over a long period of time. In the area of the opening 11 and thus the projection 10 inserted into the opening 11, the vapor diffusion barrier 16 is provided with a preferably circular tear-open perforation 19 which is adapted to the circumference of the opening. Since the vapor diffusion barrier is firmly connected to both the inner lid and the projection of the outer lid, the perforation can be separated by either pressing the projection 10 into the interior of the cabbage container 1 by pressure on the outer lid 9 or by pivoting the outer lid 9 around the hinge axis 20 of the projection 10 removes the part of the vapor diffusion barrier adhering to it upwards.

Nach dem Öffnen der Dampfdiffusionssperre 16 durch den Vorsprung 10 kann das Lebensmittel, z.B. ein Getränk, über die Trinklippe 18 in hygienisch einwandfreiem Zustand verzehrt werden. Ein erneutes Verschließen der Öffnung 11 durch den Vorsprung 10 des Außendeckels 9 führt dazu, daß der angebrochene Hohlbehälter 1 den in ihm enthaltenen Lebensmittelrest für mehrere Tage bzw. Wochen frischhält.After the vapor diffusion barrier 16 has been opened by the projection 10, the food, for example a drink, can be consumed in a hygienically perfect state via the drinking lip 18. A renewed closing of the opening 11 by the projection 10 of the outer lid 9 leads to the opened hollow container 1 keeping the food residue contained therein fresh for several days or weeks.

Mit 17 ist schließlich noch eine die Oberseite zumindest des Außendeckels 9 im wesentlichen vollständig bedeckende, als Werbeträger dienende Außenschicht bezeichnet, an der auch eine Aufreißlasche zum Verschwenken des Außendeckels 9 um die Gelenkachse 20 vorgesehen sein kann.Finally, 17 denotes an outer layer which essentially covers the upper side of at least the outer cover 9 and serves as an advertising medium and on which a tear-open tab can also be provided for pivoting the outer cover 9 about the hinge axis 20.
