Description

Die Erfindung betrifft einen Seitenfaltenbeutel aus flexibler, mehrschichtiger Folie, deren Innenschicht schweißbar ist, in einer Ausbildung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a gusseted bag made of flexible, multilayer film whose inner layer is weldable, in an embodiment according to the preamble of claim 1.

Bei einem bekannten Beutel dieser Art ( DE 20017182 U1 ) sind die Seitenfaltenhälften außenseitig entlang der oberen Randkanten verbunden, um eine Abdichtung herbeizuführen, die durch das Umfalten der Endbereiche und Festlegen der umgefalteten Endbereiche an der benachbarten Seitenfaltenhälfte zusätzlich verbessert wird.In a known bag of this type ( DE 20017182 U1 ), the gusset halves are externally joined along the upper marginal edges to provide a seal which is further enhanced by folding over the end portions and securing the folded end portions to the adjacent gusset half.

Die Erfindung befaßt sich mit dem Problem einer weiteren Verbesserung der Abdichtung der Seitenfalten an ihren oberen Enden. Die Erfindung löst dieses Problem durch einen Seitenfaltenbeutel mit den Merkmalen des Anspruchs 1. Hinsichtlich weiterer Ausgestaltungen wird auf die Ansprüche 2 bis 4 verwiesen.The invention addresses the problem of further improving the sealing of gussets at their upper ends. The invention solves this problem by a gusseted bag with the features of claim 1. With regard to further embodiments, reference is made to the claims 2 to 4.

Die Einbettung der oberen Randkanten nach der Umfaltung der oberen Endbereiche der Seitenfalten in einen Schweißverbindungsbereich ist sichergestellt, daß auch dann eine vollständige und sichere Abdichtung der Seitenfalten an ihren oberen Enden eintritt, wenn kein besonderer Verschluß entlang der oberen Randkanten der Seitenfalten, sei es durch Schweißen oder durch Kleben, vorgesehen wird. Denn der Schweißverbindungsbereich bildet eine vollständige Abdichtung, die auch unabhängig von zusätzlichen Maßnahmen einen zuverlässigen Verschluß der Seitenfalten an ihren oberen Randkanten herbeiführt. Zugleich ist durch die Verbindung der Seitenfaltenbereiche mit der Beutelwand, vorzugsweise der rückseitigen Beutelwand, sichergestellt, daß die oberen Enden der Seitenfalten nicht mehr störend in den Füllraum vorspringen.The embedding of the upper marginal edges after refolding of the upper end portions of the gussets into a weld joint region ensures that complete and secure sealing of the gussets occurs at their upper ends, even if no particular seal is made along the upper marginal edges of the gussets, either by welding or by gluing, is provided. Because the Schweißverbindungsbereich forms a complete seal, which also brings about independent of additional measures a reliable closure of the gussets at their upper marginal edges. At the same time it is ensured by the connection of the gusset areas with the bag wall, preferably the rear bag wall, that the upper ends of the gussets no longer projecting disturbing into the filling space.

Die in der Zeichnung dargestellten Seitenfaltenbeutel bestehen aus einer flexiblen, mehrschichtigen, zumindest zweischichtigen Folien aus bevorzugt thermoplastischem Kunststoff. Die Innenschicht der Folie ist schweißbar und besteht beispielsweise aus einem Polyolefin wie Polyäthylen oder Polypropylen. Außenseitig können sich eine oder mehrere Schichten anschließen, die je nach den geforderten Eigenschaften von einer Metallfolie, z.B. Aluminiumfolie und/oder einer Polyesterschicht gebildet sein kann, die ihrerseits nicht schweißfähig ist, jedoch eine hohe Festigkeit und gute Bedruckbarkeit bietet.The gusseted bags shown in the drawing consist of a flexible, multi-layered, at least two-layered films of preferably thermoplastic material. The inner layer of the film is weldable and consists for example of a polyolefin such as polyethylene or polypropylene. On the outside, one or more layers may join, depending on the required properties of a metal foil, e.g. Aluminum foil and / or a polyester layer may be formed, which in turn is not weldable, but offers a high strength and good printability.

Die dargestellten Beutel haben eine Vorderwand 1 und eine deckungsgleiche Rückwand 2 sowie zwischen diese eingelegte Seitenfalten 3,4, die sich von dem nicht dargestellten Bodenende zum Kopfende des Beutels hin erstrecken und dabei im Abstand unterhalb der oberen Randkanten 5 der Beutelwände 1,2 enden. Die Beutelwände 1,2 sind mit den Seitenfalten 3,4 sowie im von Seitenfalten freien Kopfbereich des Beutels untereinander entlang ihrer Randkanten verschweißt, und zwar durch randseitige Längsschweißnähte 6,7. Auch das Bodenende wird durch eine (nicht dargestellte) Querschweißnaht verschlossen, was vor oder nach der Befüllung des Beutels mit Füllgut erfolgen kann.The bags shown have a front wall 1 and a congruent rear wall 2 and between them inserted gussets 3,4, which extend from the bottom end, not shown, to the head end of the bag and thereby end at a distance below the upper marginal edges 5 of the bag walls 1,2. The bag walls 1, 2 are welded together with the side folds 3, 4 as well as in the side region of the bag which is free of lateral folds, along their peripheral edges, by edge-side longitudinal weld seams 6, 7. Also the bottom end is by a (not shown) closed transverse weld, which can be done before or after the filling of the bag with contents.

Im Bereich des Kopfendes des Beutels ist üblicherweise eine Verschlußeinrichtung vorgesehen, die von einer Schweißnaht gebildet sein kann, die vor oder nach Befüllung des Beutels mit Füllgut angebracht wird. Sie kann auch aus einer Wiederverschlußeinrichtung bestehen, die bei der Ausführung nach Fig. 1 und 2 von Druckverschlußbändern nach Art von Nut und Feder gebildet ist. Im einzelnen besteht diese Wiederverschlußeinrichtung 8 aus zwei sich über die Beutelbreite erstreckenden Verschlußbändern 9, 10, von denen das eine an der Beutelvorderwand 1 und das andere an der Beutelrückwand 2 durch Verschweißung bzw. Heißsiegeln befestigt ist. Die Verschlußbändern 9,10 tragen Verriegelungsglieder 11, die durch Druck in gegenseitigem Eingriff überführbar sind und bei entsprechendem Zug sich aus ihrem gegenseitigen Eingriff lösen.In the region of the head end of the bag usually a closure device is provided, which may be formed by a weld, which is attached before or after filling of the bag with product. It may also consist of a reclosing device, which is formed in the embodiment of Fig. 1 and 2 of compression fastener tapes on the type of tongue and groove. In detail, this reclosing device 8 consists of two sealing strips 9, 10 extending over the width of the bag, one of which is fastened to the bag front wall 1 and the other to the bag rear wall 2 by welding or heat sealing. The fastener tapes 9, 10 carry locking members 11, which can be transferred by pressure in mutual engagement and release at a corresponding train from their mutual engagement.

Der obere Endbereich 12 beider Seitenfalten 3,4 ist entlang einer einwärts und schräg abwärts verlaufenden Faltkante 13 umgefaltet, wobei die Umfaltung zur vorderen Beutelwand 1 oder zur rückwärtigen Beutelwand 2 hin gerichtet sein kann. Die umgefalteten Endbereiche 12 der Seitenfalten 3,4 haben die Form eines rechtwinkligen Dreiecks und sind mit der ihnen jeweils zugewandten Hälfte der Seitenfalten 3,4 durch Verschweißen verbunden, wie dies in Fig. 2, 4 und 5 durch die schematisch wiedergegebene Schweißnaht 14 veranschaulicht ist. Ferner sind die umgefalteten Endbereiche 12 an ihrer Außenseite mit der benachbarten Beutelwand, bei dem dargestellten Ausführungsbeispielen mit der Beutelrückwand 2, verschweißt, wie das durch die ebenfalls schematisch wiedergegebene Schweißnaht 15 in Fig. 2, 4 und 5 veranschaulicht ist. Ferner ist auch ein an die umgefalteten Endbereiche 12 der Seitenfalten 3,4 angrenzender Bereich 16 der gleichseitigen Seitenfaltenhälften mit der benachbarten Beutelwand 2 flächig verschweißt, so daß die Schweißverbindungsbereiche die oberen Randkanten 17 der umgefalteten Endbereiche 12 einschließen.The upper end portion 12 of both gussets 3,4 is folded along an inwardly and obliquely downward extending fold edge 13, wherein the fold may be directed to the front bag wall 1 or the rear bag wall 2 out. The folded-over end portions 12 of the gussets 3, 4 have the shape of a right triangle and are connected to their respective facing half of the gussets 3, 4 by welding, as illustrated in FIGS. 2, 4 and 5 by the schematically represented weld 14 , Furthermore, the folded-over end regions 12 are welded on their outer side to the adjacent bag wall, in the illustrated exemplary embodiments with the bag rear wall 2, as is illustrated by the likewise schematically represented weld seam 15 in FIGS. 2, 4 and 5. Further, a portion 16 of the side gusset halves adjacent to the folded-over end portions 12 of the side gussets 4 is also flatly welded to the adjacent bag wall 2 so that the weld joint portions enclose the upper marginal edges 17 of the folded end portions 12.

Hierdurch ist sichergestellt, daß die oberen Enden der Seitenfalten 3,4 absolut dicht verschlossen sind, und zwar unabhängig davon, ob die aufeinanderliegenden Außenflächen der Seitenfalten 3,4 entlang den oberen Randkanten 17 noch zusätzlich mit einem Verschluß, beispielsweise einem Klebverschluß, versehen sind oder nicht.This ensures that the upper ends of the gussets 3.4 are completely sealed, regardless of whether the superimposed outer surfaces of the gussets 3.4 along the upper marginal edges 17 additionally provided with a closure, such as a glue closure, or Not.

Bei der in Fig. 3 bis 5 dargestellten Beutelausführung ist im Kopfbereich des Beutels eine Wiederverschlußeinrichtung 18 vorgesehen, die als dreischichtiger Verschlußstreifen ausgebildet ist, der sich über die gesamte Beutelbreite erstreckt. Die beiden Außenschichten 19,20 sind jeweils mit der Innenseite der benachbarten Beutelwand 1 bzw. 2 verschweißt, wie das durch die Schweißverbindungen 21,22 versinnbildlicht ist. Die Mittelschicht 23 besteht aus einem dauerhaftfähigen bzw. -klebfähigen Material auf Kunstharz- oder Kunststoffbasis, das durch Kohäsionsbruch in zwei Teilschichten trennbar ist, wenn auf die Mittelschicht 23 eine Zugkraft durch Auseinanderziehen der Beutelwände 1,2 ausgeübt wird. Nach Entnahme von Gut können die beiden getrennten Teilschichten durch Aufeinanderdrücken wieder zu einer geschlossenen Mittelschicht 23 zusammengefügt werden. Im übrigen entspricht die Ausführung nach den Fig. 3 bis 5 der Beutelausführung nach Fig. 1 und 2.In the bag embodiment shown in FIGS. 3 to 5, a reclosing device 18 is provided in the head region of the bag, which is designed as a three-layer closure strip which extends over the entire bag width. The two outer layers 19, 20 are each welded to the inside of the adjacent bag wall 1 or 2, as is symbolized by the welded joints 21, 22. The middle layer 23 is made of a resin-based or plastic-based durable material that is separable into two partial layers by cohesive failure when a tensile force is exerted on the middle layer 23 by pulling the bag walls 1, 2 apart. After removal of good, the two separate sub-layers can be joined together again by pressing together to form a closed middle layer 23. Otherwise, the embodiment according to FIGS. 3 to 5 corresponds to the bag embodiment according to FIGS. 1 and 2.
