Description

Die Erfindung betrifft einen Behälter für Schlauchbeutelverpackungen mit einem am oberen Ende offenen Körper, der einen Schlauchbeutel senkrecht in längsseitiger Ausrichtung aufnehmen kann, und mit einem mit dem Körper beweglich verbundenen und im geschlossenen Gebrauchszustand arretierbaren Deckel, der im vorderen Bereich eine Öffnung aufweist, durch den die vordere Ecke des Schlauchbeutels hindurchragen kann.The invention relates to a container for tubular bag packaging with an open body at the upper end, which can receive a tubular bag vertically in the longitudinal direction, and with a movably connected to the body and lockable in the closed state of use, which has an opening in the front area through which the front corner of the tubular bag can protrude.

Die verstärkt auftretende Nachfrage nach ökologisch sinnvollen Verpackungen hat dem Schlauchbeutel aus Polyethylen eine neue Bedeutung verschafft, da er in der Ökobilanz allen anderen Verpackungsformen, einschließlich der Mehrwegflasche aus Glas oder Kunststoff, überlegen ist. Der entscheidende Nachteil dieser Verpackungsform ist aber die schwierige Handhabbarkeit, welche den wirtschaftlichen Durchbruch dieser Verpackung bislang verhindert hat.The increasing demand for ecologically sensible packaging has given the tubular bag made of polyethylene a new meaning, as it is superior to all other forms of packaging, including the reusable bottle made of glass or plastic, in the ecological balance sheet. The decisive disadvantage of this form of packaging is the difficult handling, which has prevented the economic breakthrough of this packaging so far.

Zur leichteren Handhabung derartiger Schlauchbeutelverpackungen ist zwar bereits aus der US-A-3 255 932 ein Behälter der vorstehend genannten Art bekannt, der aber unbefriedigend ist, weil der Schlauchbeutel eine besondere Form haben muß. Dadurch wird nicht nur die Herstellung des Beutels verteuert, sondern der Behälter kann nur in Verbindung mit diesem speziell angepaßten Beutel sinnvoll benutzt werden. Bei diesem bekannten Behälter wird das obere Ende des Schlauchbeutels an der der Öffnung gegenüberliegenden Seite des Deckels dadurch gehalten, daß ein mit einem Loch versehener lappenartiger Ansatz des Schlauchbeutels durch einen Schlitz im Deckel hindurchgeführt und mittels eines durch das Loch gesteckten Stiftes arretiert wird.For easier handling of such tubular bag packaging, a container of the aforementioned type is already known from US-A-3,255,932, but is unsatisfactory because the tubular bag must have a special shape. This not only makes the production of the bag more expensive, but the container can only be used sensibly in conjunction with this specially adapted bag. In this known container, the upper end of the tubular bag held on the side of the lid opposite the opening in that a flap-like extension of the tubular bag provided with a hole is passed through a slot in the lid and locked by means of a pin inserted through the hole.

Der Erfindung liegt die Aufgabe zugrunde, den gattungsgemäßen Behälter dahingehend zu verbessern, daß er eine problemlose Aufbewahrung und sichere Bedienung einer Schlauchbeutelverpackung mit gieß- oder schüttbarem Inhalt ermöglicht.The invention has for its object to improve the generic container so that it enables easy storage and safe operation of a tubular bag packaging with pourable or pourable content.

Ein diesem Erfordernis entsprechender gattungsgemäßer Behälter ist erfindungsgemäß dadurch gekennzeichnet, daß der Deckel im hinteren Bereich mit einem nach unten ragenden Steg zusammenwirkt, der im Gebrauchszustand des Deckels die hintere Ecke des Schlauchbeutels an eine im Bereich der Rückwand des Körpers angeordnete Gegenfläche andrückt.A generic container corresponding to this requirement is characterized according to the invention in that the lid cooperates in the rear area with a downwardly projecting web which, when the lid is in use, presses the rear corner of the tubular bag against a counter surface arranged in the area of the rear wall of the body.

Der erfindungsgemäße Behälter ermöglicht es, den geöffneten Schlauchbeutel in senkrechter Position zu halten, so daß er ohne auszulaufen lagerbar ist. Weiterhin erlaubt der erfindungsgemäße Behälter die einfache Entnahme des Inhalts bei jedem Füllstand sowie die restlose Entleerung des Beutels.The container according to the invention makes it possible to hold the opened tubular bag in a vertical position so that it can be stored without leakage. Furthermore, the container according to the invention allows the contents to be removed easily at any filling level and the bag to be completely emptied.

Bei einer bevorzugten Ausführungsform der Erfindung ist der Steg am Deckel befestigt.In a preferred embodiment of the invention, the web is attached to the lid.

Der Deckel kann auf den Körper aufgesteckt oder in seinem hinteren Bereich mit der Rückwand des Körpers schwenkbar verbunden sein. In beiden Fällen ist die Oberseite des Deckels zweckmäßigerweise zu seinem vorderen Bereich hin geneigt, damit die vordere Ecke des Schlauchbeutels in der Gebrauchsstellung des Deckels aus der Öffnung herausragt und zum Abschneiden gut zugänglich ist.The cover can be placed on the body or pivotally connected in its rear area to the rear wall of the body. In both cases, the top of the lid is expediently inclined toward its front area so that the front corner of the tubular bag protrudes from the opening in the use position of the lid and is easily accessible for cutting.

Vorteilhafterweise ist der Deckel mit einem bewegbaren Verschlußelement versehen, das in einer Endstellung die Öffnung verschließt und die durch diese hindurchragende vordere Ecke des Schlauchbeutels einklemmt. Dadurch kann der geöffnete Beutel verschlossen und ein unbeabsichtigtes Herausschwappen des flüssigen Inhalts verhindert werden.The lid is advantageously provided with a movable closure element which closes the opening in an end position and clamps the front corner of the tubular bag protruding therethrough. This allows the open Bags are sealed and the liquid contents are prevented from accidentally spilling out.

Der in Fig. 1 gezeigte Behälter für Schlauchbeutelverpackungen umfaßt einen Körper 1 und einen Deckel 2., die beide aus Kunststoff, vorzugsweise Polyethylen, hergestellt sind. Der Körper 1 hat eine solche Form, daß er einen Schlauchbeutel 4 zuverlässig senkrecht in längsseitiger Ausrichtung aufnehmen kann. Der Deckel 2 ist auf den Körper 1 lösbar aufgesteckt, wobei diese beiden Teile mit einer federnden Arretierung ineinandergreifen.The container for tubular bag packaging shown in Fig. 1 comprises a body 1 and a lid 2., both of which are made of plastic, preferably polyethylene. The body 1 has such a shape that it can reliably hold a tubular bag 4 vertically in a longitudinal orientation. The lid 2 is releasably attached to the body 1, these two parts interlocking with a resilient locking.

Der im Grundriß ellipsenförmige Deckel 2 hat in seinem vorderen Bereich eine längsgerichtete linsenförmige Öffnung 3, durch die die vordere obere Ecke 5 des Schlauchbeutels 4 nach außen dringt. Zu diesem Zweck ist die Oberseite des Deckels 2 zu seinem vorderen Bereich hin geneigt. Um die richtige Positionierung und sichere Fixierung des Schlauchbeutels 4 im Körper 1 sicherzustellen, ist der Deckel 2 auf der Innenseite im hinteren Bereich mit einem nach unten ragenden Steg 6 versehen, und der Körper 1 ist mit einem korrespondierenden Vorsprung 7 versehen. Wenn der Deckel 2 auf den Körper 1 aufgesteckt wird, dann wird die hintere obere Ecke 8 des Schlauchbeutels 4 zwischen dem Steg 6 des Deckels 2 und dem Vorsprung 7 des Körpers 1 eingeklemmt. Zur Verbesserung der Klemmwirkung sind die zusammenwirkenden Klemmflächen des Steges 6 und des Vorsprungs 7 zur Längsachse des Körpers 1 geneigt. Dadurch wird der Schlauchbeutel 4 in jedem Füllzustand senkrecht gehalten und kann nicht kollabieren, wozu er mit zunehmender Entleerung neigt, wenn der Innendruck abnimmt. Bei dem beschriebenen Klemmvorgang wird zugleich die hintere obere Ecke 8 des Beutels 4 nach unten gedrückt, wodurch sich die vordere obere Ecke 5 des Beutels deutlich aufrichtet und so besser durch die Öffnung 3 des Deckels 2 geführt und leicht abgeschnitten werden kann.The cover 2, which is elliptical in plan, has in its front region a longitudinal lens-shaped opening 3 through which the front upper corner 5 of the tubular bag 4 penetrates to the outside. For this purpose, the top of the cover 2 is inclined towards its front area. In order to ensure the correct positioning and secure fixation of the tubular bag 4 in the body 1, the lid 2 is provided on the inside in the rear area with a web 6 projecting downwards, and the body 1 is provided with a corresponding projection 7. When the lid 2 is placed on the body 1, the rear upper corner 8 of the tubular bag 4 is clamped between the web 6 of the lid 2 and the projection 7 of the body 1. To improve the clamping effect, the cooperating clamping surfaces of the web 6 and the projection 7 are inclined to the longitudinal axis of the body 1. As a result, the tubular bag 4 is held vertically in every filling state and cannot collapse, which is why it increases with emptying tends when the internal pressure decreases. In the clamping process described, the rear upper corner 8 of the bag 4 is at the same time pressed down, as a result of which the front upper corner 5 of the bag stands up clearly and can thus be better guided through the opening 3 of the lid 2 and easily cut off.

Die Öffnung 3 des Deckels 2 ist mit einem Verschlußelement in Form einer elastischen Federlasche 9 ausgestattet, welche mit Hilfe einer Griffzunge in zwei stabile Endlagen bewegt werden kann. Diese Endstellungen erreicht die Federlasche 9 jeweils in paralleler Anlage zum linken bzw. rechten Rand 10 der Öffnung 3 des Deckels 2. Um den aufgeschnittenen Schlauchbeutel 4 zu verschließen, wird die durch die Öffnung 3 nach außen vorstehende vordere obere Ecke 5 des Beutels zwischen dem Rand 10 der Öffnung 3 und der Federlasche 9 eingeklemmt, indem diese in die andere Endlage bewegt wird. Zum Öffnen des Schlauchbeutels 4 kann die Federlasche 9 in die andere Endstellung zurückbewegt werden.The opening 3 of the cover 2 is equipped with a closure element in the form of an elastic spring clip 9, which can be moved into two stable end positions with the aid of a grip tongue. These end positions each reach the spring tab 9 in parallel contact with the left or right edge 10 of the opening 3 of the lid 2. In order to close the cut-open tubular bag 4, the front upper corner 5 of the bag protruding outwards through the opening 3 becomes between the edge 10 of the opening 3 and the spring clip 9 is clamped by moving it into the other end position. To open the tubular bag 4, the spring tab 9 can be moved back into the other end position.

In den Fig. 4 bis 8 ist eine zweite Ausführungsform eines Behälters für Schlauchbeutelverpackungen gezeigt, der einen näherungsweise rechteckigen Grundriß hat. Bei dieser Ausführungsform ist der Deckel 2' in seinem hinteren Bereich mit der Rückwand 11 des Behälters 1' schwenkbar verbunden. Genauer gesagt, der Körper 1' und der Deckel 2' sind einstückig aus Kunststoff, vorzugsweise Polyethylen, hergestellt, wobei ihr Verbindungsbereich scharnierartig ausgebildet ist. Bei dieser Ausführungsform kann ein besonderer Vorsprung des Körpers 1' entfallen, weil durch die Schwenkbewegung des Deckels 2' gewährleistet ist, daß die hintere obere Ecke 8 des Schlauchbeutels 4 im geschlossenen Gebrauchszustand des Deckels 2' zwischen dem Steg 6' desselben und der Rückwand 11 des Körpers 1' zuverlässig eingeklemmt wird.4 to 8, a second embodiment of a container for tubular bag packaging is shown, which has an approximately rectangular plan. In this embodiment, the lid 2 'is pivotally connected in its rear region to the rear wall 11 of the container 1'. More specifically, the body 1 'and the cover 2' are made in one piece from plastic, preferably polyethylene, with their connection area being designed like a hinge. In this embodiment, a special projection of the body 1 'can be omitted because the pivoting movement of the cover 2' ensures that the rear upper corner 8 of the tubular bag 4 in the closed use state of the cover 2 'between the web 6' thereof and the rear wall 11 of the body 1 'is reliably clamped.

Die zweite Ausführungsform des Behälters unterscheidet sich von der ersten Ausführungsform ferner durch die Ausbildung des dem Deckel zugeordneten Verschlußelements. Im Bereich der Öffnung 3' des Deckels 2' sind zwei V-förmig gespreizte Flügel 12 angeordnet, welche mit Hilfe eines auf dem Deckel 2' angebrachten Schiebers 13 in eine geschlossene parallele Lage zueinander gebracht werden können. Zu diesem Zweck wird der Schieber 13 von der in Fig. 5 gezeigten Stellung in die in Fig. 6 gezeigte Stellung nach vorne verschoben, wodurch die beiden Flügel 12 zwangweise einander angenähert werden und die dazwischen angeordnete vordere obere Ecke 5 des Schlauchbeutels 4 zwischen sich einklemmen. Um den Ausguß des Schlauchbeutels 4 wieder zu öffnen, wird der Schieber 13 in seine in Fig. 5 gezeigte Ausgangslage zurückgeschoben, wodurch sich die Flügel 12 spreizen und die vordere Ecke 5 des Beutels nicht mehr eingeklemmt wird.The second embodiment of the container also differs from the first embodiment in the design of the closure element associated with the lid. In the area of the opening 3 'of the cover 2', two V-shaped wings 12 are arranged, which are attached to the cover 2 'by means of one Slider 13 can be brought into a closed parallel position to each other. For this purpose, the slide 13 is shifted forward from the position shown in FIG. 5 into the position shown in FIG. 6, as a result of which the two wings 12 are forcibly brought closer to one another and clamp the intermediate upper front corner 5 of the tubular bag 4 between them . In order to open the spout of the tubular bag 4 again, the slide 13 is pushed back into its starting position shown in FIG. 5, as a result of which the wings 12 spread and the front corner 5 of the bag is no longer pinched.

Die in den Fig. 9 bis 11 gezeigte dritte Ausführungsform unterscheidet sich von der vorstehend erläuterten zweiten Ausführungsform lediglich durch die Ausbildung des dem Deckel zugeordneten Verschlußelementes. Die in dem Deckel 2' ausgebildete Öffnung 3' ist mit einem Visier 14 ausgestattet, welches mit Hilfe eines auf dem Deckel 2' angebrachten Drehknopfes 15 in zwei stabile Endlagen bewegt werden kann. Zum Verschließen des aufgeschnittenen Schlauchbeutels 4 wird das Visier 14 mit dem Drehknopf 15 gegenüber der in Fig. 10 gezeigten Ausgangsstellung im Uhrzeigersinn in die in Fig. 11 gezeigte Endstellung verdreht. Dadurch wird die durch die Öffnung 3' des Deckels 2' hindurchragende vordere Ecke 5 des Schlauchbeutels 4 zwischen der Vorderkante des Visiers 14 und dem dieser zugekehrten Rand 10' der Deckelöffnung 3' eingeklemmt und somit zugehalten. Um den Ausguß des Schlauchbeutels 4 wieder zu öffnen, wird das Visier 14 mit dem Drehknopf 15 im Gegenuhrzeigersinn in seine in Fig. 10 gezeigte Ausgangsstellung zurückgedreht.The third embodiment shown in FIGS. 9 to 11 differs from the second embodiment explained above only in the design of the closure element assigned to the cover. The opening 3 'formed in the cover 2' is equipped with a visor 14 which can be moved into two stable end positions by means of a rotary knob 15 attached to the cover 2 '. To close the cut-open tubular bag 4, the visor 14 is rotated clockwise with the rotary knob 15 relative to the starting position shown in FIG. 10 into the end position shown in FIG. 11. As a result, the front corner 5 of the tubular bag 4 protruding through the opening 3 'of the lid 2' is clamped between the front edge of the visor 14 and the edge 10 'of the lid opening 3' facing it, and is thus locked. In order to open the spout of the tubular bag 4 again, the visor 14 is rotated counterclockwise with the rotary knob 15 into its starting position shown in FIG. 10.

Die in den Fig. 12 bis 15 gezeigte vierte Ausführungsform unterscheidet sich von der ersten Ausführungsform durch die Ausbildung des dem Deckel zugeordneten Verschlußelementes. Bei dieser Ausführungsform ist die Öffnung3'' des Deckels 2'' rautenförmig. Die Federlasche 9' ist durch ein Scharnier 16 in zwei relativ zueinander verschwenkbare Hälften unterteilt. Das vordere Ende der Federlasche 9' ist am Deckel 2'' angelenkt. Das über die Öffnung 3'' hinausragende hintere Ende der Federlasche 9' ist über ein weiteres Scharnier 16 mit einer Blattfeder 17 verbunden, deren beide Enden sich am Deckel 2'' abstützen. Die Federlasche 9' und die Blattfeder 17 können als einstückiges Bauteil aus Kunststoff gegossen sein, wobei die Scharniere 16 als Filmscharniere ausgebildet sind.The fourth embodiment shown in FIGS. 12 to 15 differs from the first embodiment in the design of the closure element assigned to the cover. In this embodiment, the opening 3 ″ of the cover 2 ″ is diamond-shaped. The spring tab 9 'is divided by a hinge 16 into two halves which can be pivoted relative to one another. The front end of the spring tab 9 'is articulated on the cover 2''. The rear end of the spring tab protruding beyond the opening 3 '' 9 'is connected via a further hinge 16 to a leaf spring 17, the two ends of which are supported on the cover 2''. The spring tab 9 'and the leaf spring 17 can be cast as a one-piece component from plastic, the hinges 16 being designed as film hinges.

Wenn die Federlasche 9' an dem als Griff dienenden hinteren Ende erfaßt und in die Mittelstellung gebracht wird, dann nimmt ihre Länge zu und die Blattfeder 17 wird ausgelenkt. Nach Überschreiten ihrer Mittelstellung bewegt sich die Federlasche 9' unter der Wirkung der Blattfeder 17 selbsttätig in die andere Endstellung, in der sie unter der Vorspannkraft der Blattfeder 17 stabil gehalten ist. In beiden Endstellungen der Federlasche 9' werden deren durch das Scharnier 16 verbundene geradlinigen Bereiche an den Rand 10'' der rautenförmigen Öffnung 3'' des Deckels 2'' angedrückt.When the spring tab 9 'is gripped at the rear end serving as a handle and is brought into the central position, its length increases and the leaf spring 17 is deflected. After exceeding its central position, the spring tab 9 'automatically moves under the action of the leaf spring 17 into the other end position, in which it is kept stable under the biasing force of the leaf spring 17. In both end positions of the spring tab 9 ', the rectilinear regions connected by the hinge 16 are pressed against the edge 10' 'of the diamond-shaped opening 3' 'of the cover 2' '.
