The invention relates to a bag packaging made of composite film, in particular a vacuum packaging, in the form of a parallelepiped, with the following features:
  • a) in the upper region of the bag packaging, a rectangular closure part is formed by placing opposing walls against one another, which is delimited by an upper longitudinal side as the end edge and by a lower longitudinal side,
  • b) a closure seam extends over the entire length of the rectangular closure part,
  • c) an upper edge of the closure seam and a lower edge run approximately parallel and at a distance from the long sides.

EP-A 0 298 302 zeigt eine solche Beutelverpackung mit Aufreißhilfe. Es handelt sich hierbei um eine Vakuumverpackung aus Verbundfolie mit einer Aufreißhilfe in Form eines auf die Folie aufgeschweißten quer verlaufenden Aufreißstreifens, der sich unterhalb der Verschlußnaht an der Oberseite der Verpackung und parallel zu dieser entlang-zieht und in einer aus der Verbundfolie ausgestanzten Grifflasche endet. Die Aufreißhilfe besteht hier also in einem Streifen, der separat hergestellt und auf die Verbundfolie aufgesiegelt werden muß. Beim Aufreißen der Verpackung entsteht eine Öffnung entlang dieses Aufreißstreifens, also parallel zur oberen Verschlußnaht.EP-A 0 298 302 shows such a bag packaging with a tear-open aid. It is a vacuum packaging made of composite film with a tear-open aid in the form of a transverse tear strip welded onto the film, which runs below the sealing seam on the top of the packaging and parallel to it, and ends in a grip tab punched out of the composite film. The tear-open aid here consists of a strip that has to be produced separately and sealed onto the composite film. When the packaging is torn open, an opening is created along this tear strip, that is to say parallel to the upper closure seam.

Die vorliegende Erfindung hat nun die Aufgabe, einen Beutel zu schaffen, der mit besonders wirtschaftlichen Mitteln ein rasches Öffnen des Beutels durch einfaches Aufreißen gestattet, wobei der Öffnungsvorgang zuverlässig bei jedem Beutel in gleicher Weise abläuft, während darüber hinaus ein Öffnungsbereich freigegeben wird, der als Schüttülle dient.The present invention has for its object to provide a bag that allows a quick opening of the bag by simply tearing open with particularly economical means, wherein the opening process runs reliably for each bag in the same way, while also opening an area that is released as Serves as a spout.

Zur Lösung dieser Aufgabe ist die erfindungsgemäße Beutelverpackung mit den Merkmalen a) bis c) dadurch gekennzeichnet, daß

  • d) im mittleren Bereich der Verschlußnaht ein Schweißbereich vorgesehen ist,
  • e) ein oberer Rand des Schweißbereichs etwa zwischen dem oberen Rand der Verschlußnaht und der oberen Längsseite verläuft,
  • f) ein unterer Rand des Schweißbereichs etwa zwischen dem unteren Rand der Verschlußnaht und der unteren Längsseite verläuft,
  • g) im Schweißbereich ein Ausschnitt vorgesehen ist, der zumindest einen ersten Rand sowie einen hieran anschließenden und hierzu etwa rechtwinklig stehenden zweiten Rand aufweist,
  • h) der zweite Rand im wesentlichen parallel zu den Längsseiten verläuft und etwa zwischen dem unteren Rand des Schweißbereichs und dem unteren Rand der Verschlußnaht liegt,
  • i) der erste Rand sich von dem zweiten Rand nach oben erstreckt.
To achieve this object, the bag packaging according to the invention with the features a) to c) is characterized in that
  • d) a welding area is provided in the central area of the closure seam,
  • e) an upper edge of the welding area runs approximately between the upper edge of the closure seam and the upper longitudinal side,
  • f) a lower edge of the welding area runs approximately between the lower edge of the closure seam and the lower longitudinal side,
  • g) a cutout is provided in the welding area, which has at least a first edge and a second edge adjoining it and approximately at right angles thereto,
  • h) the second edge runs essentially parallel to the long sides and lies approximately between the lower edge of the welding area and the lower edge of the closure seam,
  • i) the first edge extends upward from the second edge.

Überraschenderweise bewirkt das Ausstanzen des erfindungsgemäßen dreieckigen Ausschnitts, daß die Aufreißrichtung und damit auch die entstehende Öffnung immer gleich sind,ohne eine zusätzlich angebrachte Aufreißhilfe oder eine Perforation zu benötigen.Surprisingly, the punching out of the triangular cutout according to the invention means that the tear-open direction and thus also the opening that is created are always the same, without the need for an additional tear-open aid or perforation.

Zunächst wird auf die Figuren 1 bis 3 Bezug genommen. Aus Fig. 1 ist ein erfindungsgemäßer Beutel in vollständig verschlossenem Zustand zu entnehmen, der so umgeschlagen bzw. eingefalzt ist, daß er einen Körper bildet, der im wesentlichen die Form eines Parallelepipeds 1 mit einer flachen Oberseite aufweist, auf welche zwei dreieckige Lappen 3 umgeschlagen werden.First, reference is made to FIGS. 1 to 3. From Fig. 1, a bag according to the invention can be seen in the completely closed state, which is folded over or crimped in such a way that it forms a body which essentially has the shape of a parallelepiped 1 with a flat top, onto which two triangular tabs 3 are folded will.

Wegen der speziellen Form des gebildeten Umschlags, die an sich üblich ist, bildet man am oberen Abschnitt des Beutels einen rechteckigen oberen Endbereich 4 aus, der sich bezüglich der rechteckigen Oberseite 2 des Beutels quer zwischen den Spitzenbereichen der dreieckigen Lappen 3 erstreckt.Because of the special shape of the envelope formed, which is common per se, a rectangular upper end region 4 is formed on the upper section of the bag, which is relative to one another the rectangular top 2 of the bag extends transversely between the tip regions of the triangular tabs 3.

Dieser rechteckige Bereich 4, der gemäß Fig. 2 nach oben übersteht, sobald die dreieckigen Lappen 3 aus der in Fig. 1 gezeigten Stellung aufgeklappt sind, wird tatsächlich dadurch gebildet, daß die einander gegenüberliegenden Enden des Beutels gegeneinander angelegt werden.This rectangular area 4, which protrudes upwards according to FIG. 2, as soon as the triangular tabs 3 are opened from the position shown in FIG. 1, is actually formed by the opposite ends of the bag being placed against one another.

Die Längsseite 5 des rechteckigen Bereichs, die die Oberkante dieses Bereichs bildet, wird somit dadurch gebildet, daß die Abschlußkanten der gegenüberliegenden Seiten des Beutels im oberen Abschnitt desselben nebeneinander gelegt werden. Die untere Längsseite 6 wird durch Falze der Enden der gegenüberliegenden Beutelseiten relativ zu den Beutelabschnitten gebildet, die die Oberseite 2 und die Lappen 3 bilden.The longitudinal side 5 of the rectangular area, which forms the upper edge of this area, is thus formed in that the end edges of the opposite sides of the bag are placed side by side in the upper section thereof. The lower longitudinal side 6 is formed by folding the ends of the opposite bag sides relative to the bag sections that form the top 2 and the tabs 3.

Der Beutel wird im Bereich 4 in herkömmlicher Weise mit Hilfe einer Schweißnaht 7 verschlossen, die sich über dessen gesamte Länge im wesentlichen im halben Abstand von der oberen (5) und unteren (6) Längsseite erstreckt. Diese Schweißnaht, die beispielsweise durch Wärmeeinwirkung gelegt wird, verschließt den Beutel hermetisch.The bag is closed in the area 4 in a conventional manner with the aid of a weld seam 7, which extends over its entire length essentially half the distance from the upper (5) and lower (6) long sides. This weld seam, which is created, for example, by the action of heat, hermetically seals the bag.

Erfindungsgemäß ist die Ausbildung eines Ausschnitts 8 vorgesehen, der bei dem dargestellten Ausführungsbeispiel dreieckförmig ist, wobei diese Aussparung einen senkrecht zu den Seiten 5 und 6 verlaufenden Rand 9 aufweist, der sich in einem Rand fortsetzt, der parallel zu diesen Längsseiten 5 und 6 angeordneten verläuft, wobei die beiden Ränder 9 und 10 durch eine Kante miteinander verbunden sind, die so schräg verläuft, daß ein Ausschnitt in Form eines rechtwinkligen Dreiecks entsteht.According to the invention, a cutout 8 is provided which is triangular in the exemplary embodiment shown, this cutout having an edge 9 running perpendicular to the sides 5 and 6, which continues in an edge which runs parallel to these longitudinal sides 5 and 6 , wherein the two edges 9 and 10 are connected to each other by an edge which runs obliquely so that a cutout in the form of a right-angled triangle is formed.

Dieser Ausschnitt verläuft durch die beiden Wandungen, die den rechteckigen Endbereich 4 bilden, beispielsweise indem er mit Hilfe eines entsprechend geformten Werkzeugs eingestanzt wird.This cutout runs through the two walls that form the rectangular end region 4, for example, by is punched in using an appropriately shaped tool.

Dieser Ausschnitt 8 ist in einem Schweißbereich 11, der bei dem dargestellten Ausführungsbeispiel rechteckförmig ist, ausgebildet, wobei das obere Ende des Randes 9 des Ausschnitts 8 von der Oberkante des Schweißbereichs 11 aus nach oben übersteht. Dieser Schweißbereich 11 ist im wesentlichen im mittleren Abschnitt des Bereichs 4 ausgebildet. Bei dem dargestellten Ausführungsbeispiel ist dieser Bereich gegenüber der Mitte des Bereichs 4 leicht nach links versetzt.This cutout 8 is formed in a welding area 11, which is rectangular in the exemplary embodiment shown, the upper end of the edge 9 of the cutout 8 projecting upward from the upper edge of the welding area 11. This welding area 11 is essentially formed in the central section of area 4. In the illustrated embodiment, this area is slightly offset to the left from the center of area 4.

Schließlich ist es erfindungsgemäß auch vorgesehen, in dem rechteckigen Bereich 4 zwei seitliche Schweißzonen 12 und 13 auszubilden, die vorzugsweise von den Schmalseiten des rechteckigen Bereichs 4 aus verlaufen. Wie aus der Zeichnung ersichtlich ist, ist der mittlere Schweißbereich 11 beiderseits angeordnet und überdeckt die Schweißnaht 7, während die Zonen 12 und 13 zwischen der Schweißnaht 7 und der unteren Längsseite 6 des rechteckigen Bereichs 4 angeordnet sind.Finally, it is also provided according to the invention to form two lateral welding zones 12 and 13 in the rectangular area 4, which preferably run from the narrow sides of the rectangular area 4. As can be seen from the drawing, the middle welding area 11 is arranged on both sides and covers the weld seam 7, while the zones 12 and 13 are arranged between the weld seam 7 and the lower longitudinal side 6 of the rectangular area 4.

Zum Öffnen des erfindungsgemäßen Beutels werden die Lappen 3 aus der in Fig. 1 dargestellten Lage so umgeschlagen, daß sie sich in der aus Fig. 2 zu entnehmenden Stellung befinden.To open the bag according to the invention, the tabs 3 are turned over from the position shown in FIG. 1 so that they are in the position shown in FIG. 2.

Der Verbraucher faßt nun mit einer Hand den rechten Teil des nach oben vorstehenden rechteckigen Bereichs 4 und mit der anderen Hand den linken Abschnitt dieses Bereichs.The consumer now grips the right part of the upwardly projecting rectangular area 4 with one hand and the left section of this area with the other hand.

Anschließend übt er mit der anderen Hand eine Zugkraft nach oben im wesentlichen in Richtung des Pfeiles in Fig. 4 aus, um so das Aufreißen des Beutels zu veranlassen.Then, with the other hand, he exerts an upward tensile force essentially in the direction of the arrow in FIG. 4, so as to cause the bag to tear open.

Wegen des Ausschnitts 8 erfolgt dieses Aufreißen in der einzig möglichen Weise entlang den Linien, die schematisch in Fig. 4 gestrichelt eingezeichnet sind, so daß der gesamte linke Teil des Bereichs 4 aufgerissen wird. Fig. 5 und auch Fig. 6 zeigen den Beutel jeweils nach dem Aufreißen.Because of the cutout 8, this tearing takes place in the only possible way along the lines which are shown schematically in FIG. 4, so that the whole left part of area 4 is torn open. Fig. 5 and also Fig. 6 each show the bag after tearing.

Wie aus Fig. 6 ersichtlich ist, bildet sich im oberen Abschnitt des Beutels ein Spalt 14, der nach dem Anheben der Abschlußkanten des Beutels unter Ausformung einer Schüttülle eine Öffnung bildet.As can be seen from FIG. 6, a gap 14 is formed in the upper section of the bag, which forms an opening after the end edges of the bag have been raised while forming a filling nozzle.

Daran wird deutlich, daß der Ausschnitt 8 zum Öffnen des Beutels Sollbruchlinien in der Weise festlegt, daß ein einfaches, zuverlässiges und bei allen Beuteln gleichbleibendes Öffnen möglich wird.This makes it clear that the cutout 8 for opening the bag defines predetermined breaking lines in such a way that a simple, reliable opening which is the same for all bags becomes possible.

Die Fig. 7 und 8 veranschaulichen zwei Phasen bei der Herstellung des oberen Endbereichs des erfindungsgemäßen Beutels.7 and 8 illustrate two phases in the manufacture of the upper end portion of the bag according to the invention.

Aus Fig. 7 ist ersichtlich, daß die gegenüberliegenden Seiten des Beutels in Höhe ihrer Oberkanten durch Verschweißen in den Bereichen 11, 12, 13 in der in Fig. 7 dargestellten Weise vorläufig verschlossen werden, sobald das zu verpackende Gut in den Innenraum 1 des Beutels eingefüllt wurde.From Fig. 7 it can be seen that the opposite sides of the bag at the level of their upper edges are temporarily closed by welding in the areas 11, 12, 13 in the manner shown in Fig. 7, as soon as the goods to be packaged in the interior 1 of the bag was filled.

Anschließend wird gemäß der Darstellung in Fig. 8 der Ausschnitt 8 ausgestanzt, worauf man einen Unterdruck anlegt, um im Innenraum des Beutels ein Vakuum zu erzeugen, und schließlich wird der Beutel völlig dicht verschlossen, indem entlang der Linie 7 eine Schweißnaht gelegt wird.Subsequently, the cutout 8 is punched out, as shown in FIG. 8, whereupon a vacuum is applied in order to create a vacuum in the interior of the bag, and finally the bag is closed completely tightly by making a weld along line 7.

Nun müssen nur noch die Lappen 3 umgeschlagen und fixiert werden, damit sie die aus Fig. 1 ersichtliche vollständig verschlossene Position einnehmen.Now only the flaps 3 have to be turned over and fixed so that they assume the completely closed position shown in FIG. 1.

Der in der Zeichnung dargestellte Beutel kann natürlich in der so gebildeten Form verwendet werden, doch bildet er vorzugsweise eine Innenumhüllung, die sich innerhalb einer Außenumhüllung befindet, so daß ein doppelwandiges Paket entsteht, beispielsweise zur Vakuumerpackung von gemahlenem oder ungemahlenem Kaffee.The pouch shown in the drawing can of course be used in the form thus formed, but it preferably forms an inner wrapper which is within an outer wrapper is so that a double-walled package is created, for example for vacuum packaging of ground or unground coffee.

Selbstverständlich ist die Erfindung nicht nur auf diesen Verwendungszweck beschränkt. Auch wenn sie in Verbindung mit einem besonderen Ausführungsbeispiel erläutert wurde, so liegt es doch auf der Hand, daß sie keinesfalls (darauf) beschränkt ist und daß zahlreiche Veränderungen und Modifizierungen daran möglich sind, die völlig in den Rahmen der Erfindung fallen.Of course, the invention is not limited to this purpose only. Even if it was explained in connection with a particular exemplary embodiment, it is obvious that it is in no way restricted (to) and that numerous changes and modifications are possible that fall entirely within the scope of the invention.
