Abstract

Closure, esp. a plastics cap for bottles, has, in the region of the opening, a gastight foil which is joined to the closure. Pref. the foil consists of a PVA layer sandwiched between polyethylene layers and is bonded to the closure. Prodn. of the closure involves injection moulding the plastics closure (1) about the foil (6). USE/ADVANTAGE - The closure is esp. a plastics cap for a jar or bottle for contg. instant coffee, edible oil or the like. It is gastight and can be recycled without problems.

Description

Die Erfindung betrifft einen Verschluß für eine Dose oder Flasche, insbesondere einen Flaschenverschluß aus Kunststoff.The invention relates to a closure for a can or Bottle, in particular a plastic bottle cap.

Verschlüsse für Behältnisse sind hinlänglich bekannt; so werden beispielsweise Gläser für Instant-Kaffee mit einem Kunststoffdeckel verschlossen, der auf seiner Innenseite eine Kaschierung aus einer Alufolie aufweist, die mit einer Wachsschicht beschichtet ist, durch die beim Aufdrehen des Deckels auf das Glas eine nahezu gasdichte Verbindung entsteht. Nachteilig hieran ist jedoch, daß vor dem Recycling des Kunststoffdeckels die Alufolie unbedingt entfernt werden muß, da ansonsten ein Recycling des Kunststoffdeckels nicht möglich ist.Closures for containers are well known; so are glasses for instant coffee with a Plastic lid closed, one on the inside Laminated from an aluminum foil that with a Wax layer is coated, by which when turning the Lid on the glass an almost gastight connection arises. The disadvantage of this, however, is that before recycling of the plastic cover, the aluminum foil must be removed must, since otherwise a recycling of the plastic cover is not is possible.

Die Problematik stellt sich anders dar bei einem Verschluß aus Kunststoff für Flaschen, die Lebensmittel aufnehmen, deren Haltbarkeit wesentlich davon abhängt, daß kein Sauerstoff in die Flasche eindringen kann. Ein solches Lebensmittel ist beispielsweise Öl, das in Glasflaschen abgepackt ist, die mit einem Kunststoffverschluß versehen sind. Die Haltbarkeit eines derart aufbewahrten Öls liegt etwa bei einem Jahr, da aufgrund der ständigen Sauerstoff-Diffusion durch den Kunststoffdeckel hindurch nach dieser Zeit eine Oxidation des Öls einsetzt.The problem is different with a closure made of plastic for bottles that hold food, the durability of which essentially depends on the fact that no Oxygen can enter the bottle. Such one Food is, for example, oil in glass bottles is packed, provided with a plastic closure are. The shelf life of an oil stored in this way is about a year because of the constant Diffusion of oxygen through the plastic cover oxidation of the oil occurs during this time.

Die der Erfindung zugrundeliegende Aufgabe liegt demzufolge darin, einen Verschluß für ein Behältnis zu schaffen, der problemlos recyclebar ist und der darüber hinaus gasdicht ist.The object underlying the invention is therefore in creating a closure for a container which is easily recyclable and is also gas-tight is.

Die Aufgabe wird erfindungsgemäß gelöst durch eine, im Bereich der Öffnung angeordnete gasdichte Folie, die mit dem Verschluß in Verbindung steht. Das bedeutet, daß bei einem Schraubverschluß die Folie durch den Verschlußdeckel auf die stirnseitige Öffnung des Behältnisses gepreßt wird, die Folie die Öffnung demzufolge vollständig abdeckt und so der Inhalt gasdicht abgeschlossen ist.The object is achieved by a, in Area of the opening arranged gas-tight film with the Closure communicates. That means that with one Screw the foil through the sealing cap on the the front opening of the container is pressed, the film consequently completely covers the opening and thus the contents is sealed gas-tight.

Nach einer anderen Ausführungsform ist die Folie mit dem Verschluß verbunden; so trägt bei einem aufsteckbaren Verschluß mit einem nach Art eines U ausgebildeten, ringförmigen Aufsatz, der auf die stirnseitige Öffnung aufsteckbar ist, der innere Schenkel des U-förmig ausgebildeten, ringförmigen Aufsatzes die Folie.According to another embodiment, the film with the Fastener connected; so contributes to an attachable Closure with a U-shaped ring-shaped attachment on the front opening is attachable, the inner leg of the U-shaped trained, ring-shaped attachment the film.

Die Folie selbst ist nach einem besonderen Merkmal der Erfindung dreilagig ausgebildet, wobei die mittlere Lage im wesentlichen gasundurchlässig ist und die beiden anderen Schichten als Träger für die mittlere Folienlage dienen. Als gasdichte mittlere Folienlage bietet sich insbesondere eine Folie aus PVOH (Polyvinylalkohol) an; die untere und die obere Schicht können hierbei aus PE bestehen. Die Recyclefähigkeit eines derartigen Verschlusses steht außer Frage, insbesondere da sich PVOH bei Erwärmung vollständig auflöst. The film itself has a special feature Invention formed three layers, the middle layer in is essentially gas impermeable and the other two Layers serve as supports for the middle layer of film. As A gas-tight middle film layer is particularly suitable PVOH (polyvinyl alcohol) film; the lower and the The upper layer can consist of PE. The Such a closure is not recyclable Question, especially since PVOH completely changes when heated dissolves.  

Ein Verfahren zur Herstellung eines Verschlusses zeichnet sich dadurch aus, daß die Folie in einem Arbeitsgang beim Spritzen des Kunststoffverschlusses mit umspritzt wird. D.h.. die Kunststoffolie wird vor dem Spritzvorgang auf das Spritzwerkzeug gelegt.A method of making a closure draws is characterized in that the film in one operation Injection molding of the plastic closure is encapsulated. Ie .. the plastic film is applied to the Injection mold placed.

In der Zeichnung sind zwei Ausführungsformen eines Verschlusses für ein Behältnis dargestellt.In the drawing, two embodiments are one Shown closure for a container.

Fig. 1 zeigt einen auf eine Flasche aufsteckbaren Verschluß; Fig. 1 shows a cap that can be plugged onto a bottle;

Fig. 2 zeigt einen Schraubdeckel, beispielsweise für ein Glas; Fig. 2 shows a screw cap, for example for a glass;

Fig. 3 zeigt den Aufbau der Folie. Fig. 3 shows the structure of the film.

Gemäß Fig. 1 setzt sich der aus PE bestehende Verschluß 1 aus einem nach Art eines U ausgebildeten, ringförmigen Aufsatz 2 und einem Verschlußdeckel 3 zusammen. Der Verschlußdeckel 3 ist mit dem ringförmigen Aufsatz 2 durch eine Kunststofflasche 4 verbunden.Referring to FIG. 1, the fastener 1 consisting of PE annular attachment 2 and a closing lid 3 is formed in the manner of a U from a together. The closure lid 3 is connected to the annular attachment 2 by a plastic tab 4 .

Der ringförmige Aufsatz 2, der auf den Flaschenhals 5 stirnseitig aufgepreßt wird, weist einen äußeren Schenkel 2a und einen inneren Schenkel 2b auf, wobei der innere Schenkel 2b stirnseitig die Folie 6 trägt. The annular attachment 2 , which is pressed onto the bottle neck 5 on the end face, has an outer leg 2 a and an inner leg 2 b, the inner leg 2 b carrying the film 6 on the end face.

Bei der in Fig. 2 dargestellten Ausführungsform ist der Deckel 7 auf den Behälterkragen 8 beispielsweise eines Glases aufschraubbar. Stirnseitig auf dem Kragen 8 liegt die Folie 9, die bei Aufschrauben des Deckels 7 auf den Behälterkragen als Dichtung fungiert.In the embodiment shown in FIG. 2, the cover 7 can be screwed onto the container collar 8, for example of a glass. On the face of the collar 8 is the film 9 , which acts as a seal when the cover 7 is screwed onto the container collar.

Der Aufbau einer Folie 6 bzw. 9 ergibt sich aus Fig. 3; die mittlere Folienlage besteht hierbei aus PVOH. Sie wird umgeben von jeweils einer Lage PE. Im eigentlichen Sinne gasdicht ist lediglich die Lage aus PVOH, während die Lagen aus PE nur als Trägerlage bzw. Trägerschicht fungieren, um der Folie die erforderliche Stabilität zu verleihen.The structure of a film 6 or 9 results from Fig. 3; the middle foil layer consists of PVOH. It is surrounded by a layer of PE. In the actual sense, only the layer made of PVOH is gas-tight, while the layers made of PE only act as a carrier layer or carrier layer in order to give the film the required stability.
