Description

Die Erfindung bezieht sich auf einen Behälter für flüssige oder rieselfähige Materialien, mit einem das Füllmaterial aufnehmenden, flexiblen Beutel, der von einem formbeständigen Behältnis umgeben ist, wobei der Beutel an seiner Außenseite mit einer im Bereich einer Öffnung im Behältnis angeordneten Ausgießeinrichtung dicht verbunden ist und die den Ausgußkanal der Ausgießeinrichtung umgebende Verbindungszone nahe dem Umfang des Ausgußkanals vorgesehen ist.The invention relates to a container for liquid or free-flowing materials, with a flexible bag which holds the filling material and is surrounded by a dimensionally stable container, the outside of the bag being tightly connected to a pouring device arranged in the region of an opening in the container, and the connecting zone surrounding the pouring channel of the pouring device is provided near the periphery of the pouring channel.

Bei einem bekannten Behälter dieser Art (US-A-3 119 543) ist die Ausgießeinrichtung an dem flexiblen Beutel befestigt. Die Ausgießeinrichtung weist einen Halsabschnitt auf, auf den ein Deckel zum Verschließen des Beutels aufschraubbar ist. Der Beutel wird dadurch in das Behältnis eingesetzt, daß der Beutel in den Karton eingeführt wird und dann der Halsabschnitt der Ausgießeinrichtung durch eine entsprechende Öffnung im Deckel des Kartons geführt wird, wobei eine umlaufende Nut an dem Halsabschnitt vorgesehen sein kann, hinter die Teile des Randes der Öffnung einrasten können. Dieser bekannte Behälter weist jedoch den Nachteil auf, daß die Dichtheit des Behälters von der Güte der Verbindung zwischen dem flexiblen Beutel und der Ausgießeinrichtung abhängt, weshalb die Werkstoffe für den flexiblen Beutel, die Ausgießeinrichtung und gegebenenfalls der Klebstoff aufeinander abgestimmt sein müssen, wodurch sich eine Beschränkung bei der Auswahl des Werkstoffs ergibt. Daher kann nicht immer der für das Füllmaterial geeignete Werkstoff verwendet werden. Umgekehrt sind für den bekannten Behälter nicht alle Füllmaterialien verwendbar.In a known container of this type (US-A-3 119 543) the pouring device is attached to the flexible bag. The pouring device has a neck section, onto which a lid for closing the bag can be screwed. The bag is inserted into the container by inserting the bag into the carton and then passing the neck portion of the pouring device through a corresponding opening in the lid of the carton, whereby a circumferential groove can be provided on the neck portion behind the parts of the rim can snap into the opening. However, this known container has the disadvantage that the tightness of the container depends on the quality of the connection between the flexible bag and the pouring device, which is why the materials for the flexible bag, the pouring device and, if appropriate, the adhesive must be matched to one another, so that a Restriction in the selection of the material results. Therefore, the material suitable for the filling material cannot always be used. Conversely, not all filling materials can be used for the known container.

Es ist Aufgabe der Erfindung, einen umweltfreundlichen Behälter dieser Art so auszubilden, daß die Abstimmung der Werkstoffe für Beutel, Ausgießeinrichtung und gegebenenfalls Klebstoff unabhängig vom Füllmaterial erfolgen kann.It is an object of the invention to design an environmentally friendly container of this type so that the materials for the bag, pouring device and optionally adhesive can be matched independently of the filling material.

Dies wird erfindungsgemäß dadurch erreicht, daß der flexible Beutel den Ausgußkanal an der inneren Seite der Ausgießeinrichtung im flachen Zustand überdeckt.This is achieved according to the invention in that the flexible bag covers the pouring channel on the inside of the pouring device in the flat state.

Die erfindungsgemäße Art der Verbindung zwischen Beutel und Ausgießeinrichtung ermöglicht es, daß das Füllmaterial mit der Ausgießeinrichtung bis zur Öffnung des Behälters nicht in Berührung kommt, so daß der Werkstoff für die Ausgießeinrichtung und der für den Beutel nach den besonderen Anforderungen, die an diese Teile gestellt werden, ausgewählt werden können. Die Erfindung gestattet es zum ersten Male, in einfacher Weise einen Behälter für empfindliches Füllmaterial zu schaffen, der mit einer Ausgießeinrichtung versehen ist.The type of connection between the bag and pouring device according to the invention makes it possible that the filling material does not come into contact with the pouring device until the opening of the container, so that the material for the pouring device and for the bag according to the special requirements placed on these parts can be selected. The invention makes it possible for the first time to easily create a container for sensitive filling material, which is provided with a pouring device.

Bei einem vollständig aus Metall bestehenden Behälter (US-A-2 008 084), der somit einer anderen Gattung zuzuordnen ist, geht im Gegensatz zur Erfindung bei diesem die Wand unter der Auslauföffnung hindurch.In the case of a container made entirely of metal (US-A-2 008 084), which is therefore to be assigned to a different genus, in contrast to the invention, the wall in this case passes under the outlet opening.

Die Erfindung bezieht sich weiter auf die Ausgestaltung der Ausgießeinrichtung sowie auf ein Verfahren zur Herstellung der neuen Behälter, das dadurch gekennzeichnet ist, daß bei aus Karton, faltbarem Kunststoff und dergleichen bestehendes Behältnis der Beutel in Schlauchform an den Mantel des flachgefalteten Zuschnitts für das Behältnis angebracht und nach dem Auffalten des Behältnisses die Ausgießeinrichtung an der Außenseite des Beutels, z. B. durch Verkleben, Versiegeln oder dergleichen, dicht mit diesem verbunden wird.The invention further relates to the design of the pouring device and to a method for producing the new container, which is characterized in that in the case of a container made of cardboard, foldable plastic and the like, the bag is attached in tubular form to the jacket of the flat-folded blank for the container and after unfolding the container, the pouring device on the outside of the bag, for. B. by gluing, sealing or the like, tightly connected to this.

Ein prismatischer Kartonbehälter 1 trägt an seinem oberen Ende die Ausgießeinrichtung 2. Diese besteht aus einem Deckel 3 mit Flanschen 4, mittels deren die Ausgießeinrichtung in das obere Ende des Kartonbehälters 1 eingesetzt ist. Die Enden 5 der Flanschen springen über die Mantelfläche des Behälters 1 vor und weisen eine Nut 6 auf, die dem umgefalteten Rand 7 des Behälters 1 entgegengerichtet ist. Der Querschnitt dieser Nut ist so gewählt, daß der umgefaltete Rand 7 darin Platz findet. Die Randkante 8 untergreift nach dem Einschieben der Ausgießeinrichtung 2 eine Stufe 9, so daß die Ausgießeinrichtung in der Behälteröffnung sicher verankert ist.A prismatic cardboard container 1 carries the pouring device 2 at its upper end. This consists of a lid 3 with flanges 4, by means of which the pouring device is inserted into the upper end of the cardboard container 1. The ends 5 of the flanges project over the outer surface of the container 1 and have a groove 6 which is directed towards the folded edge 7 of the container 1. The cross section of this groove is chosen so that the folded edge 7 can be accommodated therein. The edge 8 engages under a step 9 after insertion of the pouring device 2, so that the pouring device is securely anchored in the container opening.

Die Ausgießeinrichtung ist mit einem Kragen 10 versehen in den eine Ausgießtülle 11 drehbar eingesetzt ist. Der hülsenförmige Teil 12 der Tülle weist Vorsprünge 13 auf, mit der die Tülle in einer Ringstufe des Kragens 10 gehalten ist. Zum Einführen der Tülle weist der Kragen 10 Ausnehmungen 14 auf.The pouring device is provided with a collar 10 in which a pouring spout 11 is rotatably inserted. The sleeve-shaped part 12 of the spout has projections 13 with which the spout is held in an annular step of the collar 10. To insert the spout, the collar 10 has recesses 14.

Der untere Rand der Hülse 12 ist sägezahnartig geformt, so daß mehrere schräglaufende Schneiden 15 vorhanden sind. Im Bereich des Kragens 10 ist ein im Kartonbehälter 1 enthaltener Beutel 16 aus flexiblem Material mit dem Deckel 3 dicht verbunden, was z. B. durch Kleben oder Schweißen erfolgen kann. Die Verbindungsstelle 17 weist Ringform auf und schließt den vom hülsenförmigen Teil 12 der Tülle 11 gebildeten Ausgußkanal ein.The lower edge of the sleeve 12 is shaped like a sawtooth, so that several oblique cutting edges 15 are present. In the area of the collar 10, a bag 16 made of flexible material contained in the cardboard container 1 is tightly connected to the cover 3, which, for. B. can be done by gluing or welding. The connection point 17 has a ring shape and closes that of the sleeve-shaped part 12 of the spout 11 pouring spout formed.

Zum Öffnen des Behälters wird die Tülle 11 um 90° gedreht, wie dies in Fig. 2 angedeutet ist. Dabei läuft jeder Vorsprung 13 an eine Schrägfläche 18 des Kragens 10 auf, so daß die Tülle gezwungen ist, eine schraubenlinienförmige Bewegung auszuführen. Hierbei dringen die Spitzen der sägezahnartigen Schneiden 15 des über die Ausgußöffnung flachliegenden Beutel 16 ein und schneiden eine entsprechend große kreisförmige Öffnung in die Beutelwand. Fig. 5 zeigt Kragen 10 und Hülse 12 in abgewinkelter Darstellung.To open the container, the spout 11 is rotated by 90 °, as indicated in Fig. 2. Each projection 13 runs onto an inclined surface 18 of the collar 10, so that the spout is forced to perform a helical movement. The tips of the sawtooth-like cutting edges 15 of the bag 16 lying flat over the pouring opening penetrate and cut a correspondingly large circular opening into the bag wall. Fig. 5 shows collar 10 and sleeve 12 in an angled view.

Gemäß den Fig. 6 bis 11 weist der Behälter 21 Kanisterform auf. Er besteht aus einem Faltzuschnitt, der nach Verkleben seines Mantels flach gelegt werden kann, wie Fig. 11 zeigt. Am schrägverlaufenden Teil des Kanisters ist eine Ausgießeinrichtung 22 vorgesehen, die mit Nuten 23 den Rand 24 der Behälteröffnung umgreift und dort gegebenenfalls verklebt ist. Die Ausgießvorrichtung 22 ist mit einer ebenen Fläche 25 versehen, die durch die Öffnung im Behälter 24 dem Behälterinneren zugewendet ist. Schräg zu dieser Fläche 25 ist eine Ausgießtülle 26 vorgesehen, in die ein Verschluß 27 mit einem hülsenförmigen Teil 28 drehbar eingesetzt ist. Der untere Rand 29 dieser Hülse 28 fluchtet im geschlossenen Zustand der Ausgießeinrichtung mit der Ebene 25. Der von der Hülse 28 gebildete Ausgußkanal wird von einem Bereich 30 umschlossen, in dem der flexible Beutel 31 mit der Ausgießeinrichtung dicht verbunden ist. In der Hülse 28 ist eine Öffnung 32 vorgesehen, die als Ausgußöffnung dient. Die Ausgußtülle 26 weist einen Schnabel 33 auf, um ein gezieltes Ausleeren zu ermöglichen. Zum Herstellen einer Öffnung im flexiblen Beutel 31 wird der Verschluß 27 und 180° gedreht, wodurch sein unterer Rand 29 als Messer auf die Beutelwand wirkt und einen mondförmigen Ausschnitt schafft. Die Offenstellung ist in Fig. 9 dargestellt.6 to 11, the container 21 has a can shape. It consists of a folded blank that can be laid flat after gluing its jacket, as shown in Fig. 11. On the inclined part of the canister, a pouring device 22 is provided, which surrounds the edge 24 of the container opening with grooves 23 and is glued there if necessary. The pouring device 22 is provided with a flat surface 25 which faces the interior of the container through the opening in the container 24. At an angle to this surface 25, a pouring spout 26 is provided, into which a closure 27 with a sleeve-shaped part 28 is rotatably inserted. The lower edge 29 of this sleeve 28 is aligned with the plane 25 when the pouring device is closed. The pouring channel formed by the sleeve 28 is enclosed by an area 30 in which the flexible bag 31 is tightly connected to the pouring device. An opening 32 is provided in the sleeve 28 and serves as a pouring opening. The pouring spout 26 has a beak 33 to enable targeted emptying. To create an opening in the flexible bag 31, the closure 27 is rotated through 180 °, as a result of which its lower edge 29 acts as a knife on the bag wall and creates a moon-shaped cutout. The open position is shown in Fig. 9.

Bei empfindlichem Füllgut ist es zweckmäßig den flexiblen Beutel aus einer Mehrschichtfolie herzustellen. Die innere Schicht kann aus einem, mit dem Füllgut verträglichen Werkstoff bestehen und der der äußersten Schicht mit Bedacht auf eine gute Verbindbarkeit mit dem Material der Ausgießeinrichtung ausgewählt werden. Zwischen diesen Schichten kann sich eine Sperrschicht oder dergleichen z. B. aus Aluminium und/oder eine Träger- bzw. Bewahrungsschicht befinden.In the case of sensitive contents, it is advisable to manufacture the flexible bag from a multilayer film. The inner layer can consist of a material which is compatible with the filling material and that of the outermost layer can be selected with a view to good connectivity with the material of the pouring device. A barrier layer or the like, e.g. B. made of aluminum and / or a support or preservation layer.

Die Behälter werden vorzugsweise mit eingelegtem Beutel, der bereits mit der Ausgießeinrichtung dicht verbunden ist, an den Verbraucher geliefert, der den Inhalt durch den offenen Boden des Beutels einfüllt und den Boden durch Verschweißen oder Verkleben schließt. Dann wird der Boden des Kartonbehälters gefaltet.The containers are preferably supplied to the consumer with an inserted bag, which is already tightly connected to the pouring device, who fills the contents through the open bottom of the bag and closes the bottom by welding or gluing. Then the bottom of the cardboard box is folded.

Obwohl der Behälter im gefalteten Zustand, wie ihn Fig. 11 zeigt, für den Transport nur wenig Raum benötigt, kann es zweckmäßig sein, Faltkarton mit eingelegtem am Boden offenen Beutel von der Ausgießeinrichtung getrennt zu transportieren. Der Verbraucher stellt den Karton auf, setzt die Ausgießeinrichtung ein und verschweißt diese mit dem Beutel. Dann wird der Behälter, der hierbei am Kopf steht gefüllt und, wie beschrieben, verschlossen.Although the container requires only little space for transport in the folded state, as shown in FIG. 11, it may be expedient to transport the folding carton with the bag open at the bottom separately from the pouring device. The consumer places the box, inserts the pouring device and welds it to the bag. Then the container standing upside down is filled and closed as described.

Es ist aber auch möglich, den Faltzuschnitt in flacher Form und den flexiblen Beutel in Form eines Schlauches zu transportieren, den Zuschnitt aufzufalten und den leeren Schlauch oder den nur einseitig offenen flexiblen Beutel einzuführen, außen mit der Ausgießeinrichtung zu versehen und diese gegebenenfalls am Behältnis zu verankern. Wird die Ausgießeinrichtung vor dem Einsetzen des flexiblen Beutels mit diesem verbunden, so kann der Beutel im gefüllten Zustand eingesetzt und die Ausgießeinrichtung anschließend verankert werden. Alternativ zum Einsetzen des leeren oder gefüllten flexiblen Beutels in das standfeste Behältnis kann dieses auch durch Ummantelung des Beutels z. B. während des Füllvorganges, gebildet werden.However, it is also possible to transport the folded blank in flat form and the flexible bag in the form of a tube, unfold the blank and insert the empty tube or the flexible bag, which is only open on one side, to provide the outside with the pouring device and, if necessary, to the container anchor. If the pouring device is connected to the flexible bag before it is inserted, the filled bag can be inserted and the pouring device can then be anchored. As an alternative to inserting the empty or filled flexible bag into the stable container, this can also be done by sheathing the bag, e.g. B. during the filling process.
