Description

Standbeutel Stand-up pouches
Die Erfindung betrifft einen Standbeutel aus einer heiß- siegelfähigen oder -schweißbaren Kunststoffolie zur Auf¬ nahme von flüssigem und/oder pastösem Gut, mit zwei Sei¬ tenwänden, die an ihren Längskanten miteinander verbun¬ den sind, wobei zwischen den unteren Querkanten ein faltbares, zwischen den Seitenwänden liegendes, als Standboden dienendes Bodenteil und im Bereich des ande¬ ren Endes der Seitenwände ein faltbares, zwischen den Seitenwänden liegendes Deckenteil eingefügt ist und mit einer Entnahmeöffnung.The invention relates to a stand-up pouch made of a heat-sealable or weldable plastic film for holding liquid and / or pasty material, with two side walls which are connected to one another at their longitudinal edges, with a foldable, between the side walls, serving as a stand base, and in the region of the other end of the side walls, a foldable ceiling part, which is located between the side walls, and a removal opening.
Standbeutel aus Kunststoffolien sind insbesondere als Einwegverpackungen für Getränke, aber auch für Waschmit¬ tel oder dergl. bekannt. Standbeutel der gattungsgemäßen Art werden z.B. in dem deutschen Gebrauchsmuster G 89 00 883 oder auch dem deutschen Gebrauchsmuster G 89 00 882 beschrieben. In die Unterseite derartiger Beutel ist ein Standboden eingearbeitet, so daß der Beutel auch nach seinem Öffnen auf einer Unterlage aufgestellt werden kann, ohne daß der Beutelinhalt aus der Entnahmeöffnung, die im oberen Bereich ausgebildet ist, herausläuft, oder der Beutel umkippt. Außerdem ist zur Erhöhung der Stabi¬ lität bei Beuteln dieser Art im oberen Teil zwischen die Seitenwände ein zusätzliches, ähnlich wie der Standboden aufgebautes Deckenteil eingearbeitet, so daß Beutel die¬ ser Art im gefüllten Zustand eine einem Zylinder ähneln¬ de Form haben.Stand-up pouches made of plastic films are known in particular as disposable packaging for beverages, but also for detergents or the like. Stand-up pouches of the generic type are e.g. described in the German utility model G 89 00 883 or the German utility model G 89 00 882. A stand is incorporated into the underside of such bags, so that the bag can also be placed on a base after it has been opened without the contents of the bag running out of the removal opening formed in the upper region or the bag tipping over. In addition, in order to increase the stability of bags of this type, an additional cover part, similar to the base, is incorporated in the upper part between the side walls, so that bags of this type have a shape similar to a cylinder when filled.
Ein grundsätzlicher Vorteil solcher Standbeutel liegt darin, daß sie im ungefüllten Zustand sehr flach zusam¬ mengefaltet werden können und so nur wenig Platz bean¬ spruchen. Andererseits haben sie im gefüllten Zustand eine relativ große Eigenstabilität und eignen sich so insbesondere als Nachfüllpackungen für die bereits ge¬ nannten Medien.A fundamental advantage of such stand-up pouches is that they can be folded together very flat in the unfilled state and thus take up little space. On the other hand, they are filled a relatively high intrinsic stability and are therefore particularly suitable as refill packs for the media already mentioned.
Bei den bekannten Beuteln wird die Entnahmeöffnung ent¬ weder im Bereich des Deckenteils verwirklicht (deutsches Gebrauchsmuster 89 00 883) oder aber im oberen Teil ei¬ ner Seitenwand (deutsches Gebrauchsmuster 89 00 882) .In the known bags, the removal opening is realized either in the area of the ceiling part (German utility model 89 00 883) or in the upper part of a side wall (German utility model 89 00 882).
Im ersteren Fall liegt die Entnahmeöffnung zentral in der Mitte des Standbeutels und ragt in der Art einer Gießtülle hervor, die allerding aufgrund ihrer Flexibi¬ lität beim Ausgießen insbesondere beim Umfüllen in Flaschen nicht immer einen stabilen Auslauf des Mediums ermöglicht, so daß es zu Verschüttungen kommen kann.In the former case, the removal opening is located centrally in the middle of the stand-up pouch and protrudes in the manner of a pouring spout, which, however, due to its flexibility when pouring out, in particular when pouring into bottles, does not always allow a stable discharge of the medium, so that spills occur can.
Im zweiten Fall, in dem also die Entnahmeöffnung in der Seitenwand ausgebildet ist, muß der Standbeutel zum Umfüllen seines Inhaltes seitlich an das Umfüllgefäß herangeführt werden, was ebenfalls zu Problemen führen kann.In the second case, in which the removal opening is formed in the side wall, the stand-up pouch has to be moved laterally to the decanting container to transfer its contents, which can also lead to problems.
Der Erfindung liegt die Aufgabe zugrunde, einen Stand¬ beutel der eingangs genannten Art hinsichtlich seiner Handhabung be m Ausgießen zu verbessern und gleichzeitig eine einfachere Herstellmöglichkeit sicherzustellen.The object of the invention is to improve a stand-up pouch of the type mentioned at the outset with regard to its handling when pouring out and at the same time to ensure a simpler possibility of production.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Entnahmeöffnung zwischen der oberen Querkante einer Seitenwand und der entsprechenden Deckenteilkante ausge¬ bildet ist. Somit kann ein stabiles Ausgießen des Füll¬ gutes gewährleistet werden, da das Füllgut entlang der Seitenwand bis zur Entnahmeöffnung fließen kann, ohne dabei umgelenkt zu werden. Darüber hinaus ist die Her¬ stellung des erfindungsgemäßen Standbeutels einfach und kostengünstig, da nur ein Teil der Schweißnaht zwischen der oberen Querkante einer Seitenwand und der ent- sprechenden Deckenteilkante ausgespart werden muß.According to the invention, this object is achieved in that the removal opening is formed between the upper transverse edge of a side wall and the corresponding ceiling part edge. A stable pouring out of the filling material can thus be ensured, since the filling material can flow along the side wall up to the removal opening without being deflected in the process. In addition, the manufacture of the stand-up pouch according to the invention is simple and inexpensive, since only part of the weld seam between the upper transverse edge of a side wall and the speaking ceiling part edge must be recessed.
Gemäß einem bevorzugten Ausführungsbeispiel ist die Ent¬ nahmeöffnung von einem an einer Seitenwand ausgebilde¬ ten, über eine Querkante der Seitenwand vorstehenden Seitenwandlasche und einer dazu korrespondierend am Deckenteil ausgebildeten Deckenteillasche gebildet, die entlang ihrer Langskanten miteinander verbunden sind.According to a preferred exemplary embodiment, the removal opening is formed by a side wall flap which is formed on a side wall and projects beyond a transverse edge of the side wall, and a corresponding top part flap which is formed on the ceiling part and is connected to one another along its long edges.
Durch diese Lösung wird die Entnahmeöffnung von zwei Laschen gebildet, wobei die eine Lasche Teil der Seiten¬ wand ist, während die andere Lasche Teil des Deckenteils ist. Durch Verbinden entlang der Langskanten entsteht so die Entnahmeöffnung, wobei das auszufüllende Medium wieder frei entlang der Seitenwandung bis zum Ende im Bereich der Öffnung fließen kann, also nicht umgelenkt wird. Dadurch ergibt sich eine "ruhige" gleichmäßige Ausfließströmung, so daß ein präzises Umfüllen auch kleiner Mengen ohne die Gefahr des Verschüttens möglich ist. Darüber hinaus ist die Herstellung sehr einfach, weil beim Vorbereiten der einzelnen Folienteile ledig¬ lich an der Seitenwand ein überstehender Abschnitt zur Bildung der Seitenwandlasche und am Deckenteil ebenfalls lediglich ein entsprechender Überstand ausgeschnitten werden muß.As a result of this solution, the removal opening is formed by two tabs, one tab being part of the side wall, while the other tab is part of the cover part. By connecting along the long edges, the removal opening is created, the medium to be filled again being able to flow freely along the side wall up to the end in the region of the opening, that is to say not being deflected. This results in a "calm" even outflow, so that a precise transfer even of small quantities is possible without the risk of spillage. In addition, the manufacture is very simple, because when preparing the individual film parts, only a protruding section on the side wall to form the side wall flap and likewise only a corresponding protrusion on the cover part has to be cut out.
In vorteilhafter Weiterbildung der Erfindung ist vorge¬ sehen, daß in die Entnahmeöffnung ein Schraubverschlu߬ element eingesetzt ist. Mit dieser Maßnahme läßt sich die Entnahmeöffnung einfach verschließen, wenn bei¬ spielsweise nur ein Teilinhalt des Standbeutels umoder ausgegossen worden ist.In an advantageous development of the invention it is provided that a screw closure element is inserted into the removal opening. With this measure, the removal opening can be easily closed if, for example, only a partial content of the stand-up pouch has been poured or poured out.
In weiterer Ausgestaltung der Erfindung sind die Ecken¬ bereiche der Seitenwand, an der die Entnahmeöffnung ausgebildet ist, seitlich der Entnahmeöffnung dreieck- förmig bis zum Beginn der Längskanten der Entnahmeöff¬ nung mit den zugeordneten Eckbereichen des Deckenteils flächig verbunden. Dadurch entsteht beim Ausgießen eine seitliche Zuführung des auszugießenden Fluids zur Ent¬ nahmeöffnung hin, was insbesondere bei flüssigen Medien zu einem ruhigen Ausströmungen führt.In a further embodiment of the invention, the corner areas of the side wall on which the removal opening is formed are triangular to the side of the removal opening. in a flat shape up to the beginning of the longitudinal edges of the removal opening with the associated corner regions of the ceiling part. This results in a lateral supply of the fluid to be poured out to the removal opening during pouring, which leads to a smooth outflow, particularly in the case of liquid media.
In weiterer vorteilhafter Ausgestaltung ist zwischen einer Seite des Bodenteils und einer unteren Querkante einer Seitenwand im Bereich des Bodens eineIn a further advantageous embodiment, there is one between one side of the base part and a lower transverse edge of a side wall in the region of the base
Befüllöffnung vorgesehen.Dabei kann an der Seite des Boden¬ teils und an der unteren Querkante der Seitenwand im Bereich des Bodens korrespondierend ausgebildete Bodenlaschen vorge¬ sehen sein, die an ihren Langskanten miteinander verbunden sind unddie Befüllöffnung bilden. Bei dieser Lösung wird zu¬ sätzlich zur Entnahmeöffnung eine gesonderte Befüllöffnung geschaffen, wobei nach dem Befüllen die Befüllöffnung verschlossen wird, indem z.B. vom Boden her die korrespon¬ dierenden Laschen miteinander verschweißt werden können. Die Entnahme findet dann über die Entnahmeöffnung statt. Wenn die gesonderte Befüllöffnung nicht vorhanden ist, wird über die Entnahmeöffnung auch gefüllt.Filling opening is provided on the side of the base part and on the lower transverse edge of the side wall in the region of the base, correspondingly designed base flaps which are connected to one another at their long edges and form the filling opening. With this solution, a separate filling opening is created in addition to the removal opening, the filling opening being closed after filling, for example by the corresponding tabs can be welded together from the bottom. The removal then takes place via the removal opening. If the separate filling opening is not available, the filling opening is also used for filling.
In weiterer vorteilhafter Ausgestaltung der Erfindung ist vorgesehen, daß die Seitenwände mit zwischen den Querkanten beabstandet verlaufenden, nach außen gerich¬ teten Längsprägungen versehen sind.In a further advantageous embodiment of the invention, it is provided that the side walls are provided with longitudinal embossments which run at a distance between the transverse edges and are directed outwards.
Diese Längsprägungen bilden Längsfaltlinien, die in der Form von Vertiefungen in das Folienmaterial eingeprägt werden. Beim befüllten Beutel ergibt sich dadurch je nach Anzahl der Längsprägungen eine Polygonform (im Ho- rizontalschnitt gesehen) des gefüllten Behälters, also eine von der runden Form abweichende Gestaltung. Wenn z.~B. in jeder Seitenwand zwei derartige Längsprägun¬ gen beabstandet angeordnet sind, hat der am Ende erhal¬ tene Standbeutel im gefüllten Zustand die Form eines Sechsecks, so daß die Behälter zum Transport oder auch bei Präsentationen in Regalen von Einkaufsläden eng an- einanderstehend gelagert werden können, so daß weniger Totraum entsteht, wie das bei im Querschnitt runden, an¬ einander angrenzenden Behältnissen der Fall wäre.These longitudinal embossings form longitudinal fold lines which are embossed in the form of depressions in the film material. In the case of the filled bag, depending on the number of longitudinal embossings, this results in a polygon shape (seen in the horizontal section) of the filled container, that is to say a design deviating from the round shape. If e.g. ~ Example in each side wall two such Längsprägun¬ gene are spaced, at the end erhal tene stand-up pouch in the filled state has the form of Hexagons, so that the containers can be stored close together for transport or also for presentations on the shelves of shops, so that less dead space is created, as would be the case with containers which are round in cross section and adjoining one another.
Schließlich sieht eine Weiterbildung der Erfindung vor, daß die Seitenwandlasche die Deckenteillasche im wesent¬ lichen rechteckför ig ausgebildet sind und daß schlie߬ lich die Außenkontur des Beutels ein Quadrat mit einer Kantenlänge zwischen 10 und 15 cm bildet.Finally, a further development of the invention provides that the side wall flap is essentially rectangular in shape, and that the outer contour of the bag finally forms a square with an edge length between 10 and 15 cm.
Beutel dieser Art sind sehr handlich und eignen sich für die unterschiedlichsten Anwendungsmöglichkeiten.Bags of this type are very handy and are suitable for a wide variety of applications.

Die Eckbereiche lid, 11c, 10a und 10c werden ent¬ sprechend dieser Reihenfolge mit den Eckbereichen 2d, 2c, 2b und 2a der Seitenwand 2 ebenfalls dreieckförmig verschweißt.The corner areas lid, 11c, 10a and 10c are also welded triangularly in this order with the corner areas 2d, 2c, 2b and 2a of the side wall 2.
Die jeweils zur Seite weisenden Kanten von Boden- und Deckenteil werden mit den Längskanten 4 und 6 bzw. 5 undThe edges of the floor and ceiling parts facing each side are aligned with the longitudinal edges 4 and 6 or 5 and
7 ebenfalls längs verschweißt.7 also welded lengthways.
Schließlich wird die Unterkante 8 mit der ihr zugeord¬ neten Kante des Bodenteils verbunden, während die auf die Seitenwand 2 weisende untere Kante des Bodenteils 10 mit der Unterkante 9 dieser Seitenwand verschweißt wird.Finally, the lower edge 8 is connected to the edge of the base part assigned to it, while the lower edge of the base part 10 pointing to the side wall 2 is welded to the lower edge 9 of this side wall.
Das Deckenteil wird über die Länge seiner auf die Sei¬ tenwand 3 weisenden oberen Kante mit der entsprechenden oberen Kante der Seitenwand verschweißt. Die Deckenteil¬ lasche 15 dagegen wird nur entlang ihrer Längskanten 16 und 18 mit den entsprechenden Langskanten 17 und 19 der Seitenwandlasche 14 verschweißt.The cover part is welded to the corresponding upper edge of the side wall over the length of its upper edge facing the side wall 3. The cover part flap 15, on the other hand, is only welded along its longitudinal edges 16 and 18 to the corresponding long edges 17 and 19 of the side wall flap 14.
Bei einer Variante des erfindungsgemäßen Standbeutels, die ebenfalls in Figur 1 gestrichelt angedeutet ist, kann an der unteren Seite der Seitenwand 2 und der auf sie zuweisenden Fläche des Bodenteils 10 entsprechend der Seitenwand- und Deckenteillasche 14 und 15 jeweils eine Bodenlasche 2e bzw. lOe angeordnet sein. Diese Laschen können ebenfalls wieder entlang ihrer Längskan¬ ten miteinander verbunden werden, so daß dort in diesem Bereich dann eine Befüllöffnung entsteht, die nach dem Befüllvorgang flächig oder auch entlang der Kanten dann zum Verschließen des Beutels verschweißt werden kann.In a variant of the stand-up pouch according to the invention, which is also indicated by dashed lines in FIG. 1, a bottom flap 2e or 10e can be arranged on the lower side of the side wall 2 and the surface of the bottom part 10 facing it, corresponding to the side wall and top part flaps 14 and 15 his. These tabs can also be connected to one another again along their longitudinal edges, so that there in this Area then creates a filling opening, which can be welded flat after the filling process or along the edges to close the bag.
Durch das Verschweißen bzw. Versiegeln entlang der Längskanten der Deckenteillasche und der Seitenwand¬ lasche entsteht die Entnahmeöffnung 12, in die, wie Fi¬ gur 2 zeigt, ein Schraubverschlußelement eingeschweißt werden kann. Der somit erhaltene Beutel läßt sich insge¬ samt dann einfach wieder verschließen, wenn er nach der Benützung nicht vollständig entleert worden ist.Welding or sealing along the longitudinal edges of the ceiling part flap and the side wall flap results in the removal opening 12, into which, as shown in FIG. 2, a screw closure element can be welded. The bag obtained in this way can then be easily closed again if it has not been completely emptied after use.
Die Seitenwände 2 und 3 sind darüber hinaus mit beab¬ standet zueinander verlaufenden, nach außen gerichteten Längsprägungen 21 versehen, wie dies Figur 5 ebenfalls erkennen läßt.The side walls 2 and 3 are also provided with spaced-apart, outwardly directed longitudinal embossments 21, as can also be seen in FIG. 5.
Diese Längsprägungen 21, von denen jeweils zwei in dem dargestellten Ausführungsbeispiel pro Seitenwand ver¬ wirklicht sind, bewirken, daß der befüllte Beutel in der Draufsicht geschnitten entlang der Linie V-V der Figur 2 eine Form annimmt, wie sie in Figur 5 gezeigt ist. Mit dieser Sechseckform lassen sich die Beutel ohne toten Raum einfach nebeneinander anordnen. Die Figuren 3 und 4 zeigen die entsprechenden Längsschnittformen des Stand¬ beutels im Zusammenbau, wobei man erkennen kann, daß dort wo die Entnahmeöffnung 12 gebildet ist, ein über die gesamte Seitenwand glatt durchgehender Entnahmekanal gebildet ist, so daß das Ausgießen sehr einfach und gleichmäßig möglich ist. Wie die Figur 2 erkennen läßt, ist der Beutel bei diesem Ausführungsbeispiel im wesent¬ lichen quadratisch, wobei sich als bevorzugte Kanten¬ länge für die praktische Verwendung eine Länge zwischen 10 und 15 cm herausgestellt hat.These longitudinal embossments 21, of which two are realized in the exemplary embodiment shown per side wall, cause the filled bag to take a shape in plan view, cut along the line V-V of FIG. 2, as shown in FIG. 5. With this hexagon shape, the bags can be easily arranged side by side without dead space. FIGS. 3 and 4 show the corresponding longitudinal sectional shapes of the stand-up pouch in the assembly, it being possible to see that where the removal opening 12 is formed, a removal channel which is smooth over the entire side wall is formed, so that the pouring out is very simple and uniform is. As can be seen in FIG. 2, the bag in this exemplary embodiment is essentially square, a length between 10 and 15 cm having emerged as the preferred edge length for practical use.
Figuren 6 bis 9 zeigen ein zweites Ausführungsbeispiel gemäß der vorliegenden Erfindung. Das zweite Ausfüh- rungsbeispiel entspricht im wesentlichen dem ersten Aus¬ führungsbeispiel, wobei jedoch zur Bildung der Entnahme¬ öffnung 12 keine Deckenteillasche 15 am Deckenteil 11 und keine korrespondierende Seitenwandlasche 14 ausge¬ bildet ist. Bei diesem Ausführungsbeispiel wird die Ent¬ nahmeöffnung zwischen der oberen Querkante 20 der Sei¬ tenwand 2 und der entsprechenden Deckenteilkante 22 aus¬ gebildet. Der Beutel wird, wie im Zusammenhang mit dem vorherigen Ausführungsbeispiel beschrieben, verschweißt, bis auf daß der Beutel im Bereich der Entnahmeöffnung zwischen dem Deckenteil und der Seitenwand 2 offen bleibt, Wie in Figur 7 gezeigt ist, kann in die Entnahmeöffnung 12 ein Schraubver¬ schlußelement eingeschweißt werden. Selbstverständlich kann auch bei diesem Ausführungsbeispiel im Bereich des Bodenteils eine Befüllöffnung, wie zuvor beschrieben, vorgesehen werden.Figures 6 to 9 show a second embodiment according to the present invention. The second execution The exemplary embodiment corresponds essentially to the first exemplary embodiment, but in order to form the removal opening 12, no ceiling part flap 15 is formed on the ceiling part 11 and no corresponding side wall flap 14 is formed. In this exemplary embodiment, the removal opening is formed between the upper transverse edge 20 of the side wall 2 and the corresponding ceiling part edge 22. As described in connection with the previous exemplary embodiment, the bag is welded, except that the bag remains open in the area of the removal opening between the cover part and the side wall 2. As shown in FIG. 7, a screw closure element can be inserted into the removal opening 12 be welded in. Of course, a filling opening, as described above, can also be provided in this embodiment in the region of the base part.
Selbstverständlich ist die in den Ausführungsbeispielen rechteckige Formgebung der Deckenteillasche und der Sei¬ tenwandlasche durch andere Formen ersetzbar, beispiels¬ weise kann auch eine spitz zulaufende Laschenform ge¬ wählt werden, so daß eine "Gießnase" erhalten wird. Of course, the rectangular shape of the ceiling part flap and the side wall flap in the exemplary embodiments can be replaced by other shapes, for example a tapered flap shape can also be selected, so that a "pouring nose" is obtained.
