Abstract

A tubular bag package which has a fin (2) in which two strip-shaped edge regions (3) of the packaging material are connected to one another on their inner sides by peelable cold-sealing, the connection region taking up two partial regions (4) at the ends of the two edge regions (3) between which an unsealed central region (5) is located. For the complete gas-tight connection of the two edge regions (3) of the fin (2) and as an opening aid, a glued label (6) is folded over the fin edge (8), which label covers the central region (5), overlaps the two partial regions (4) of the connection region, and is connected by glueing to the fin surface on both sides of the fin (2). On one side of the fin, the glued label (6) has, at an edge located towards the package, an edge region (11) which is not connected to the fin surface and forms a gripping tab (12). The fin (2) is advantageously folded onto the package covering (13) and glued to the latter in such a way that the gripping tab (12) comes to rest at the top. <IMAGE>

Description

Die Erfindung betrifft eine Schlauchbeutelpackung mit Öffnungshilfe für stückiges Packungsgut mit einer Hülle, die aus einem flächigen, faltbaren Verpackungsmaterial gebildet ist und die eine Flosse aufweist, in der zwei streifenförmige Randbereiche des Verpackungsmaterials an ihren Innenseiten innerhalb eines Verbindungsbereichs durch eine peelfähige Kaltsiegelung miteinander verbunden sind.The invention relates to a tubular bag pack with opening aid for lumpy packaged goods with a casing which is formed from a flat, foldable packaging material and which has a fin in which two strip-shaped edge regions of the packaging material are connected to one another on their inner sides within a connecting region by a peelable cold seal.

Eine Schlauchbeutelpackung dieser Art ist aus der WO 91/13005 der Anmelderin bekannt. Bei den dort beschriebenen Schlauchbeutelpackungen bestehen die Öffnungshilfen darin, daß beide streifenförmigen Randbereiche mit jeweils einer Handhabe versehen sind, die mit beiden Händen auseinandergezogen werden, wodurch die Kaltsiegelverbindung zwischen den beiden Randzonen aufgetrennt wird und sich eine Öffnung in der Packung bildet, durch welche man dann das Packungsgut entnimmt.A tubular bag pack of this type is known from WO 91/13005 by the applicant. In the tubular bag packs described there, the opening aids consist in the fact that both strip-shaped edge areas are each provided with a handle that is pulled apart with both hands, whereby the cold seal connection between the two edge zones is separated and an opening is formed in the pack, through which one can then removes the packaged goods.

Ein Nachteil dieser bekannten Öffnungshilfe liegt darin, daß zu ihrer Betätigung beide Hände benötigt werden und daß die zum Öffnen notwendigen Handgriffe für einen mit der Packung noch unvertrauten Verbraucher ohne besondere Erklärungen oder Hinweise meist nicht unmittelbar erkennbar sind. Außerdem ist der Öffnungsvorgang in manchen Fällen mit einer Beschädigung des Verpackungsmaterials verbunden und die Entnahme des Packungsgutes dadurch erschwert.A disadvantage of this known opening aid is that both hands are required for its actuation and that the handles necessary for opening are usually not immediately recognizable to a consumer who is still unfamiliar with the package without special explanations or instructions. In addition, the opening process is in some cases associated with damage to the packaging material, making it difficult to remove the packaged goods.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, eine Schlauchbeutelpackung mit Öffnungshilfe zu schaffen, bei der zum Öffnen nur eine Hand benötigt wird und die für die Öffnung erforderliche Manipulation leicht zu erkennen ist.The invention seeks to remedy this. The invention, as characterized in the claims, solves the problem of creating a tubular bag package with an opening aid in which only one hand is required for opening and the manipulation required for the opening can be easily recognized.

Die Erfindung wird nachstehend an zwei Beispielen anhand der Figuren näher erläutert.The invention is explained in more detail below using two examples with reference to the figures.

Fig. 1 zeigt eine perspektivische Teildarstellung einer Schlauchbeutelpackung, wie sie z.B. für Dauerbackwaren oder Schokoladeriegel benutzt werden kann. Dabei ist - wie auch in den übrigen Figuren - zur Verbesserung der Darstellung, das Verpackungsmaterial übertrieben dick dargestellt. Die Packung weist - wie bei Schlauchbeutelpackungen üblich - eine Finne 1 und an den beiden Enden zwei quer zur Finne 1 verlaufende Flossen 2 auf, von der in der Teildarstellung von Fig. 1 aber nur eine zu sehen ist. Die Finne 1 bzw. die Flosse 2 bilden dabei im wesentlichen senkrecht zueinander verlaufende Verpackungsfolienbereiche, in welchen jeweils zwei streifenförmige Randbereiche 3 der Verpackungsfolie an der normalerweise dem Verpackungsgut 18 zugewandten Oberflächenseite in einem Verbindungsbereich durch Kaltsiegelung miteinander verbunden sind.Fig. 1 shows a partial perspective view of a tubular bag package, such as e.g. can be used for permanent baked goods or chocolate bars. As in the other figures, the packaging material is shown in an exaggerated thickness to improve the display. The pack has - as is customary in tubular bag packs - a fin 1 and at both ends two fins 2 running transversely to the fin 1, of which only one can be seen in the partial illustration of FIG. 1. The fin 1 or the fin 2 form essentially perpendicular to each other packaging film areas in which two strip-shaped edge areas 3 of the packaging film are connected to one another in a connection area by cold sealing on the surface side normally facing the packaged goods 18.

Im Gegensatz zu üblichen Schlauchbeutelpackungen, die - speziell auch für die Flossen - sich über die Länge der beiden miteinander zu verbindenden streifenförmigen Randbereiche 3 erstreckende Verbindungsbereiche aufweisen, ist bei der erfindungsgemäßen Schlauchbeutelpackung an der Flosse 2 der Verbindungsbereich in Form von zwei an beiden Enden der streifenförmigen Randbereiche gelegenen (in Fig. 1 durch eine strichlierte Kontur angedeuteten) Teilbereichen 4 ausgebildet, zwischen denen ein ungesiegelter Mittelbereich 5 liegt.In contrast to conventional tubular bag packs, which - especially for the fins - have connecting areas which extend over the length of the two strip-shaped edge areas 3 to be connected to one another, in the tubular bag pack according to the invention the connecting area in the form of two at the fin 2 is the strip-shaped one at both ends Sub-regions 4 (indicated by a dashed outline in FIG. 1) are formed between edge regions, between which an unsealed central region 5 lies.

Zur vollständigen gasdichten Verbindung der beiden Randbereiche 3 dient ein Klebeetikett 6, das nach der Herstellung der Grundform der Schlauchbeutelpackung (d.h. nach Ausbildung der Flosse 2) zunächst an der Außenseite einer der beiden Randbereiche 3 unter Ausbildung einer Klebeverbindung hoher Haftkraft angebracht wird, derart, daß das Klebeetikett 6 den ungesiegelten Mittelbereich 5 überdeckt und auch noch die beiden Teilbereiche 4 des Verbindungsbereiches etwas überlappt (19). Danach wird das Klebeetikett 6 in Richtung des Pfeiles 7 um die Flossenkante 8 gefaltet und der mit einem peelfähigen Kleberauftrag versehene Bereich 9 auch mit der gegenüberliegenden Flossenoberfläche 10 verbunden, wobei ein nicht mit der Kleberbeschichtung versehener Randbereich 11 mit der Flossenoberfläche 10 nicht verklebt ist und dabei eine Grifflasche 12 bildet. Dieser Zustand ist in der Schnittdarstellung der Fig. 2 gezeigt, die eine vergrößerte Schnittdarstellung entsprechend der Linie II-II von Fig. 1 darstellt. Anschließend werden auf die Oberfläche 13 der Packungshülle am Packungsende an der der Grifflasche 12 entge-gengesetzten Seite der Flosse 6, Hotmelt-Punkte 14 (siehe Fig. 2) angebracht und die Flosse unmittelbar danach, in Richtung des Pfeiles 15 (siehe Fig. 2) auf die Packungs-Hülle umgelegt und dabei durch den Hotmeltauftrag mit der Hüllenoberfläche 13 verklebt (Fig.3). Zum Öffnen der nun fertigen Schlauchbeutelpackung, wie sie sich in Fig. 3 darstellt, wird nun, wie es dem Gebraucher unmittelbar deutlich ist, die Grifflasche 12 mit einer Hand angefaßt und in Richtung des Pfeiles 16 seitlich nach oben gezogen. Dabei wird zunächst die peelfähige Klebeverbindung zwischen Klebeetikett 6 und Flosse 2 und danach die beiden Teilbereiche 4 des Verbindungsbereichs der Flosse 2 aufgeschält und schließlich - nach Auftrennung der Hotmeltverbindung zwischen Flosse 2 und Packungs-Hüllenoberfläche 13 - das Ende der Schlauchbeutelpackung aufgefaltet, so daß sich die nun geöffnete Schlauchbeutelpackung, wie in Fig. 4 gezeigt, darstellt.For the complete gas-tight connection of the two edge areas 3, an adhesive label 6 is used, which after the production of the basic shape of the tubular bag pack (ie after the formation of the fin 2) is first attached to the outside of one of the two edge areas 3 with the formation of an adhesive connection of high adhesive force, such that the adhesive label 6 covers the unsealed central area 5 and also slightly overlaps the two partial areas 4 of the connecting area (19). Then the adhesive label 6 is folded in the direction of arrow 7 around the fin edge 8 and with A region 9 provided with a peelable adhesive application is also connected to the opposite fin surface 10, an edge region 11 not provided with the adhesive coating not being glued to the fin surface 10 and thereby forming a grip tab 12. This state is shown in the sectional view of FIG. 2, which is an enlarged sectional view along the line II-II of FIG. 1. Hotmelt points 14 (see FIG. 2) are then applied to the surface 13 of the packaging envelope at the end of the package on the side of the fin 6 opposite the grip tab 12 and the fin immediately thereafter in the direction of the arrow 15 (see FIG. 2) ) folded onto the packaging envelope and thereby glued to the envelope surface 13 by the hot melt application (FIG. 3). To open the now finished tubular bag pack, as shown in FIG. 3, as is immediately clear to the user, the grip tab 12 is gripped with one hand and pulled upwards in the direction of the arrow 16. First, the peelable adhesive connection between adhesive label 6 and fin 2 and then the two partial areas 4 of the connection area of fin 2 is peeled off and finally - after the hot melt connection between fin 2 and package cover surface 13 has been separated - the end of the tubular bag package is unfolded, so that the now opened tubular bag package, as shown in Fig. 4.

Gemäß einer Variante der erfindungsgemäßen Schlauchbeutelpackung (siehe Fig. 5) ist an der mit der Packungs-Hüllenoberfläche 13 zu verklebenden Flossenseite ein Randbereich 17 des Klebeetiketts 6 um 180° aufgefaltet, so daß dieser Randbereich 17 beim Umlegen der Flosse 2 die gewünschte Klebeverbindung mit der Packungs-Hüllenoberfläche 13 eingeht.According to a variant of the tubular bag pack according to the invention (see FIG. 5), an edge region 17 of the adhesive label 6 is unfolded by 180 ° on the fin side to be glued to the package cover surface 13, so that this edge region 17 has the desired adhesive connection with the flap 2 when it is folded over Pack envelope surface 13 is received.
