Description

Die Erfindung betrifft einen tetraederförmigen Verpackungsbeutel aus einem flexiblen Folienmaterial und ein Verfahren zur Herstellung des Verpackungsbeutels.The invention relates to a tetrahedral packaging bag from a flexible film material and a method for producing the packaging bag.

Es sind tetraederförmige Verpackungsbeutel aus mit Kunststoff beschichtetem Karton für Getränke bekannt. Für die Getränkeentnahme ist der Verpackungsbeutel an einer Stelle beispielsweise mit einer von einer Folie verschlossenen Öffnung versehen, die mittels eines Trinkhalmes durchstossen werden kann. Andere Beutel können zur Bildung eines Ausgusses entlang einer Perforationslinie aufgerissen werden. Weiter sind tetraederförmige Verpackungsbeutel aus einem flexiblen Folienmaterial für mit einer Zuckermasse umhüllte Schokoladedragees bekannt. Zur Öffnung dient, wie bei vielen Beutelverpackungen, eine in einer Siegelnaht angeordnete Anreisskerbe.They are tetrahedral bags made of plastic coated Cardboard for drinks known. For the beverage withdrawal is the packaging bag at one point, for example, with one of a film sealed Opening provided that can be pierced by means of a drinking straw. Other bags may form a spout along a perforation line be torn up. Next are tetrahedral packaging bag a flexible film material for coated with a sugar mass Schokoladestraagees known. For opening, as with many pouches, one in a sealing seam arranged Anreißkerbe.

Der Erfindung liegt die Aufgabe zugrunde, einen Verpackungsbeutel der eingangs genannten Art zu schaffen, mit dem flüssige und rieselfähige feste Inhaltsstoffe dosiert über eine definierte Öffnung entnommen werden können. Der Verpackungsbeutel soll auf einfache Weise hergestellt werden können und ein einfaches Wiederverschliesssystem anbieten.The invention is based on the object, a packaging bag of the above mentioned type, with the liquid and free-flowing solid ingredients dosed over a defined opening can be removed. Of the Packaging bag should be easy to make and can offer a simple reclosure system.

Zur erfindungsgemässen Lösung führt beim Verpackungsbeutel, dass das Folienmaterial im Bereich einer Tetraederecke des Beutels einen vom Beutel abragenden, im wesentlichen schlauchförmigen und an seinem freien Ende verschlossenen Ausgussteil bildet.For inventive solution leads to the packaging bag that the film material in the region of a tetrahedral corner of the bag, one protruding from the bag, essentially tubular and closed at its free end Spout forms.

Mit der Anordnung eines vom Beutel abragenden Ausgussteils im Bereich einer Tetraederecke wird ein Verpackungsbeutel mit einer multifunktionalen Öffnung geschaffen, die sich sowohl als Trinköffnung als auch zur dosierten Entnahme von Flüssigkeiten und rieselfähigen Füllgütern eignet. Hinzu kommen die Vorteile der Tetraederform des Beutels, der gut in der Hand liegt und äusserst formstabil und standfest ist. Ein weiterer Vorteil liegt darin, dass ein einmal geöffneter Beutel mit der dem Ausgussteil gegenüber liegenden Tetraederfläche auf einer Unterlage, z.B. auf einem Tisch, abgestellt werden kann, ohne dass Füllgut ausfliesst, da sich in dieser Lage die Ausgussöffnung am höchsten Punkt des Beutels befindet.With the arrangement of a protruding from the bag spout in the area of a Tetrahedron corner becomes a packaging bag with a multifunctional opening created, both as a drinking opening as well as the metered removal of liquids and free-flowing products. Add to that the advantages the tetrahedral form of the bag, which fits well in the hand and extremely dimensionally stable and stable. Another advantage is that once opened Bag with the pouring part opposite tetrahedral surface on a base, e.g. on a table, can be turned off without that Filling out material, since in this position, the spout opening highest Point of the bag is located.

Bei einer bevorzugten Ausführungsform ist vorgesehen, dass der schlauchförmige Ausgussteil in von der Tetraederecke des Beutels weg weisender Ausgussrichtung konisch verjüngt ausgebildet ist. Die konische Ausführung des Ausgussteils hat den Vorteil, dass beispielsweise beim Öffnen mit einer Schere der Querschnitt der durch das Wegschneiden des verschlossenen Endes des Ausgussteils quer zur Ausgussrichtung entstehenden Ausgussöffnung mit zunehmendem Abstand des Schnittes vom freien Ende des Ausgussteils grösser wird. Auf diese Weise kann eine für einen bestimmten Zweck geeignete Dosieröffnung individuell eingestellt werden.In a preferred embodiment it is provided that the tubular Spout in pouring direction away from the tetrahedral corner of the bag is conically tapered. The conical design of the Spout has the advantage that, for example, when opening with a pair of scissors the cross section of the by cutting away the closed end of the Spout part transverse to the spout emerging spout opening with increasing Distance of the cut from the free end of the spout larger becomes. In this way, a suitable for a specific purpose dosing be set individually.

Zur Erleichterung der Öffnung des Verpackungsbeutels ohne Schere oder Messer kann wenigstens eine quer zur Ausgussrichtung verlaufende Einreisskerbe vorgesehen sein, wobei bei einer besonders zweckmässigen Ausbildungsform des Ausgussteils zur Bereitstellung von Dosieröffnungen mit unterschiedlichem Querschnitt wenigstens zwei in unterschiedlichem Abstand zum verschlossenen freien Ende des Ausgussteils angeordnete Einreisskerben angeordnet sein können. Um einen möglichst definierten Öffnungsquerschnitt zu erhalten, können zusätzlich zu den Einreisskerben Schwächungslinien vorgesehen werden. Die Schwächungslinien gehen von der Spitze der Einreisskerben auf und umlaufen den Ausgussteil.To facilitate the opening of the packaging bag without scissors or knives can at least one transverse to the spout tear groove be provided, with a particularly useful embodiment the spout for providing dosing with different Cross section at least two at different distances to the closed arranged tearing notches arranged free end of the spout can. In order to obtain a possible defined opening cross-section, can In addition to the tear score lines of weakness are provided. The lines of weakness go from the top of the tear scores and revolve around the spout part.

Der erfindungsgemäss von einer Tetraederecke des Beutels abragende Ausgussteil kann bei ungeöffnetem Verpackungsbeutel beispielsweise gegen eine der Beutelflächen zurückgeklappt und mittels eines an der Beutelfläche oder am Ausgussteil angeordneten Haftklebers in umgeklappter Lage fixiert werden. Auf diese Weise ist der Ausgussteil während dem Transport und der Lagerung der Verpackungsbeutel relativ gut gegen mechanische Beschädigung geschützt. Nach dem Öffnen des Verpackungsbeutels durch das Durchtrennen des Ausgussteils im Bereich seines freien Endes ergibt sich durch geeignete Anordnung des Haftklebers in Verbindung mit der Klapp- oder Faltbärkeit des Ausgussteils eine einfache Möglichkeit, den geöffneten Beutel wieder zu verschliessen. Mit diesem einfachen Verschluss kann zumindest bei rieselfähigen festen Schüttgütern ein Auslaufen des Füllgutes bei umgekippter Packung wirksam verhindert werden.The invention projecting from a tetrahedral corner of the bag spout part can with unopened packaging bag, for example, against a the bag surfaces folded back and by means of a on the bag surface or on Spout arranged pressure-sensitive adhesive are fixed in the folded position. On This is the spout during transport and storage of the Packaging bag relatively well protected against mechanical damage. After opening the packaging bag by cutting the spout in the region of its free end results from a suitable arrangement of the pressure-sensitive adhesive in conjunction with the folding or Faltbärkeit of the pouring part an easy way to close the opened bag again. With This simple closure can, at least for free-flowing solid bulk materials Leakage of the contents effectively prevented when the package is overturned become.

Das Rohrstück übernimmt bei einem Getränkebeutel die Funktion eines Trinkhalmes. Bei einer bevorzugten Ausführungsform ist der Ausgussteil von seinem verschlossenen Ende bis zu einer Einreisskerbe bzw. Aufreisslinie mit dem Rohrstück nicht fest verbunden, so dass beim Öffnen des Getränkebeutels der Ausgussteil nach dem Abtrennen vom Beutel über das Rohrstück hinweg entfernt werden kann. Hierbei wird das keimfreie Rohrstück freigelegt und kann ohne Berührung direkt zum Mund geführt werden.In particular, when using the inventive packaging bag As a beverage bag, it may prove to be useful in the spout Stiffening element, preferably a piece of plastic pipe to order. The tube piece assumes the function of a drinking straw in a beverage bag. In a preferred embodiment, the spout is of his closed end up to a tear notch or tear line with the Pipe piece not firmly connected, so that when opening the beverage bag of the Spout after removal from the bag over the pipe piece away can be. Here, the germ-free pipe section is exposed and can be brought directly to the mouth without touching.
