Abstract

A tubular bag package has a strip-like tearing zone (9) that begins with a U-shaped cut out (6) in one of the two strip-like marginal zones (2, 3) cold-sealed in a connecting zone (1) so as to form a tubular bag fin. The U-shaped cut out (6), within which the package material forms a gripping tongue (8), has legs that extend in the direction of the connecting zone (1) and the ends (7) of the legs possibly extend into said zone. The remaining section of the U-shaped cut out (6), however, is not contiguous to the connecting zone, so that possible misfits caused during production between the U-shaped cut out (6) and layers of cold-bonding agent applied on the section, as well as lateral wraping of both marginal zones (2, 3), cannot cause the adherence of the gripping tongue (8). When the gripping tongue (8) is drawn in order to open the package, the packaging material tears along approximately parallel lines (10) in the longitudinal direction, starting from the ends (7) of the cut out (6).

Description

Die Erfindung betrifft eine Schlauchbeutelpackung für stückiges Packungsgut mit einer Hülle, die aus einem flächigen, faltbaren Verpackungsmaterial gebildet ist, von dem zwei streifenförmige Randzonen an ihren Innenseiten in einem Verbindungsbereich durch eine Versiegelung, vorzugsweise durch eine peelfähige Kaltsiegelung miteinander verbunden sind, wobei in einer dieser Randzonen ein verbindungsfreier mit einer U-förmigen Durchstanzung vorgesehen ist, die mit ihren Schenkein gegen den Verbindungsbereich gerichtet ist und die den Anfang eines streifenförmigen Aufreißbereiches bildet.The invention relates to a tubular bag pack for lumpy packaged goods with a sleeve, which is formed from a flat, foldable packaging material, of which two strip-shaped edge zones on their inner sides are connected to one another in a connection area by a seal, preferably by a peelable cold seal, in one of these Edge zones a connection-free with a U-shaped punching is provided, which is directed with its legs against the connection area and which forms the beginning of a strip-shaped tear-open area.

Eine Schlauchbeutelpackung dieser Art ist aus der EP-A-399420 bekannt. Bei den dort beschriebenen Beispielen ist in beiden Randzonen jeweils ein verbindungsfreier Bereich vorgesehen, die beide übereinander angeordnet sind, während die U-förmige Durchstanzung mit einem Teil der Begrenzung dieser Bereiche übereinstimmt. Ein Nachteil ist dabei, daß selbst bei einem geringen gegeneinander Verlaufen der zwei streifenförmigen Randzonen beim Herstellungsprozeß die U-förmige Durchstanzung in den Verbindungsbereich fällt und dadurch die Öffnung erschwert wird. Ferner ist die Aufreißlasche, deren Anfang durch die U-förmige Durchstanzung begrenzt wird, nicht leicht anzufassen.A tubular bag pack of this type is known from EP-A-399420. In the examples described there, a connection-free area is provided in each of the two edge zones, both of which are arranged one above the other, while the U-shaped punching coincides with part of the delimitation of these areas. A disadvantage here is that even if the two strip-shaped edge zones run slightly against one another during the manufacturing process, the U-shaped punching falls into the connection area and the opening is thereby made more difficult. Furthermore, the tear tab, the beginning of which is limited by the U-shaped punching, is not easy to handle.

Diese Aufgabe wird durch die erfindungsgemäße Schlauchbeutelpackung der eingangs der Beschreibung genannten Art gelöst, die dadurch gekennzeichnet ist, daß die U-förmige Durchstanzung innerhalb des verbindungsfreien Bereichs vorgesehen ist und an ihrer U-Basis nicht an den Verbindungsbereich angrenzt, daß die streifenförmige Randzone, die die U-förmige Durchstanzung aufweist, mit einem Bereich, der den größten Teil dieser Durchstanzung umfaßt, über den freien Rand der anderen Randzone hinausragt, und daß an dieser Randzone ein Bereich, der von dieser Durchstanzung an drei Seiten umfaßt wird, nach außen auf die Oberfläche der Packung umgefaltet ist.This object is achieved by the tubular bag pack according to the invention of the type mentioned at the beginning, which is characterized in that the U-shaped punching is provided within the connection-free area and does not adjoin the connection area at its U-base, that the strip-shaped edge zone, the has the U-shaped punching, with an area which comprises the largest part of this punching, protrudes beyond the free edge of the other edge zone, and that at this edge zone an area which from this punching is covered on three sides, is folded outwards onto the surface of the pack.

Die Ansprüche 2 bis 5 betreffen vorteilhafte Ausgestaltungen der Erfindung.Claims 2 to 5 relate to advantageous refinements of the invention.

Die Erfindung wird nachstehend anhand der Figuren näher erläutert, wobei das Verpackungsmaterial zum besseren Verständnis übertrieben dick dargestellt ist.The invention is explained in more detail below with reference to the figures, the packaging material being exaggeratedly thick for better understanding.

Zur Herstellung dieser Packung geht man - bei dem nachfolgend erläuterten Beispiel - von einem dreischichtig aufgebauten Verpackungsmaterial aus. Dieses Verpackungsmaterial besteht - von der Packungsaußenseite ausgehend - aus einer 0,015 bis 0,20 mm starken biaxial gereckten Polypropylenfolie (OPP-Folie), aus einer 0.007 bis 0.009 mm starken, bedruckten Aluminiumfolie, einem Papier einer Grammatur von 30 bis 100 g/m2 und einer im Profil aufgebrachten Kaltkleberbeschichtung auf Latexbasis (2 bis 7 g/m2 Feststoff). Die OPP-Folie verleiht dem Verbund mechanische Festigkeit, das Papier bildet die Trägerschicht des Verbundmaterials und die Aluminiumfolie die Schicht, welche die Gasdichtheit des Verbundes gewährleistet.For the manufacture of this pack - in the example explained below - a three-layer packaging material is used. Starting from the outside of the pack, this packaging material consists of a 0.015 to 0.20 mm thick biaxially stretched polypropylene film (OPP film), a 0.007 to 0.009 mm thick, printed aluminum film, a paper with a grammage of 30 to 100 g / m 2 and a latex-based cold adhesive coating applied in the profile (2 to 7 g / m 2 solid). The OPP film gives the composite mechanical strength, the paper forms the carrier layer of the composite material and the aluminum foil the layer that ensures the gas tightness of the composite.

An der Verpackungsmaschine werden nun - für jede herzustellende Packung - an einem der Ränder der von der Rolle abgezogenen Verpackungsmaterialbahn eine U-förmige Durchstanzung angebracht, die mit ihren Schenkeln gegen die Mitte der Verpackungsmaterialbahn gerichtet ist. Unmittelbar danach wird die Verpackungsmaterialbahn um die kontinuierlich zugeführten Packungsgutstücke, z.B. Waffeln, gefaltet, ihre Ränder innerhalb eines streifenförmigen Verbindungsbereiches miteinander versiegelt und die beiden miteinander versiegelten Randzonen, die man als "Finne" bezeichnet, so auf die Packungsoberfläche umgeschlagen, daß die die U-förmige Durchstanzung enthaltende Randzone nach außen zu liegen kommt. Der die Packungsgutstücke umschließende Verpackungsmaterial-Schlauch wird nun jeweils zwischen zwei aufeinanderfolgenden Packungsgutstückan mit zwei parallel zueinander verlaufenden Quersiegelungsnähten versehen und durch Trennschnitte zwischen diesen beiden Quersiegelungsnähten in Einzelschlauchbeutelpackungen unterteilt. Diese Quersiegelungen bilden dann die von der Packungshülle abstehenden "Flossen" der Schlauchbeutelpackung.A U-shaped punching is now attached to the packaging machine - for each package to be produced - on one of the edges of the packaging material web pulled off the roll, the legs of which are directed towards the center of the packaging material web. Immediately afterwards, the web of packaging material is folded around the continuously supplied packaged goods, for example waffles, its edges are sealed to one another within a strip-shaped connecting area, and the two are sealed to one another Edge zones, which are referred to as "fins", are turned over onto the packaging surface in such a way that the edge zone containing the U-shaped punching comes to lie on the outside. The packaging material tube enclosing the packaged goods is now each provided with two transverse sealing seams running parallel to one another between two successive packaged goods and divided into individual tubular bag packs by separating cuts between these two transverse sealing seams. These transverse seals then form the "fins" of the tubular pouch that protrude from the packaging envelope.

Fig. 1 zeigt nun schematisch in perspektivischer Darstellung eine auf diese Weise hergestellte Schlauchbeutelpackung für Waffeln. Man erkennt die in einem streifenförmigen Verbindungsbereich 1 durch eine Kaltsiegelung miteinander verbundenen streifenförmigen Randzonen 2 und 3, die als "Finne" auf die Oberfläche der Packungshülle umgeschlagen sind. Die nach außen zu liegen kommende Randzone 2 ist dabei breiter als die Randzone 3, so daß zwischen dem Rand 4 und dem Verbindungsbereich 1 in der Randzone 2 ein verbindungsfreier Bereich 5 verbleibt, der über die unten liegende Randzone 3 hinausreicht. Innerhalb dieses verbindungsfreien Bereiches 5 ist die U-förmige Durchstanzung 6 vorgesehen, die mit den Enden 7 ihrer Schenkel bis in den Verbindungsbereich 1 hineinreicht. Diese Durchstanzungen 6 können entweder bereits in der angelieferten Verpackungsmaterialbahn vorhanden sein oder an der Verpackungsmaschine kurz vor Bildung des Verpackungsmaterialschlauches eingestanzt werden. In dem verbindungsfreien Bereich 5 der Randzone 2 bildet das Verpackungsmaterial innerhalb der U-förmigen Durchstanzung 6 eine Grifflasche 8, die den Anfang eines "virtuellen" streifenförmigen Aufreißbereiches 9 mit zueinander parallelen Begrenzungslinien 10 formt. Beim Öffnen der Packung wird die Grifflasche in Richtung des Pfeiles 11 gezogen, wobei das Verpackungsmaterial bei geeigneter Auswahl an den Enden 7 der U-förmigen Durchstanzung etwa entlang den gedachten Linien 10 einreißt.1 now schematically shows a perspective view of a tubular bag pack for waffles produced in this way. One recognizes the strip-shaped edge zones 2 and 3 which are connected to one another in a strip-shaped connection area 1 by a cold seal and which are turned over as "fins" on the surface of the packaging envelope. The edge zone 2 coming to the outside is wider than the edge zone 3, so that between the edge 4 and the connection area 1 in the edge zone 2 there remains a connection-free area 5 which extends beyond the edge zone 3 located below. Within this connection-free area 5, the U-shaped punching 6 is provided, which extends with the ends 7 of its legs into the connection area 1. These punchings 6 can either already be present in the delivered packaging material web or can be punched into the packaging machine shortly before the packaging material tube is formed. In the connection-free area 5 of the edge zone 2, the packaging material forms a grip tab 8 within the U-shaped punching 6, which forms the beginning of a "virtual" strip-shaped tear-open area 9 with boundary lines 10 parallel to one another. When the package is opened, the grip tab is pulled in the direction of the arrow 11, the packaging material being selected at the ends 7 of the U-shaped punching tears approximately along the imaginary lines 10.

Fig. 2 zeigt die Schlauchbeutelpackung nun in der Aufsicht in einer Teildarstellung, wobei an der Stelle der U-förmigen Durchstanzung die Packungshülle zum Teil aufgebrochen dargestellt ist.Fig. 2 shows the tubular bag package in a top view in a partial view, the package cover being partially broken open at the location of the U-shaped punching.

Man erkennt den Rand 12 der unten liegenden Randzone 3, über den der verbindungsfreie Bereich 5 der Randzone 2 übersteht. In einem der U-förmigen Durchstanzung benachbarten Teilbereich 13, in den die Enden 7 der U-förmigen Durchstanzung hineinreichen, ist der Kaltkleber auf die Randzone 2 in einer Façonbeschichtung in Form eines Kreuzlinienrasters aufgebracht, wodurch die Peelfähigkeit der Kaltsiegelung in diesem Teilbereich 13 höher wird als in dem übrigen Bereich 14 des Verbindungsbereiches 1. Dies erleichtert das Abziehen des Aufreißbereiches beim Öffnungsvorgang.One can see the edge 12 of the edge zone 3 lying below, over which the connection-free area 5 of the edge zone 2 projects. In a sub-area 13 adjacent to the U-shaped punching, into which the ends 7 of the U-shaped punching extend, the cold adhesive is applied to the edge zone 2 in a façon coating in the form of a cross line grid, which increases the peelability of the cold seal in this sub-area 13 than in the remaining area 14 of the connecting area 1. This makes it easier to pull off the tear-open area during the opening process.

Erfindungsgemäß wird bei der Hestellung der Schlauchbeutelpackung nach oder bei dem Anbringen der U-förmigen Durchstanzung in der Verpackungsmaterialbahn ein Bereich des Verpackungsmaterials, der von dieser Durchstanzung an drei Seiten umfaßt wird, auf die an der Oberfläche der Packung zuliegenkommende Seite des Verpackungsmaterials um 180° umgefaltet. Diese Faltung ist besonders stabil, wenn das verwendete mehrschichtige Verpackungsmaterial eine Aluminiumfolie enthält.According to the invention, when the tubular bag pack is produced after or when the U-shaped punching is made in the packaging material web, an area of the packaging material, which is covered by this punching on three sides, is folded over by 180 ° to the side of the packaging material which is coming to the surface of the pack . This folding is particularly stable if the multilayer packaging material used contains an aluminum foil.

Mehrschichtige Verpackungsmaterialien, die bei der erfindungsgemäßen Schlauchbeutelpackung beim Öffnungsvorgang etwa längs parallelen Linien weiterreißen, sind in der veröffentlichten Internationalen Patentanmeldung WO 91/06488 beschrieben.Multi-layer packaging materials that tear along longitudinal lines in the tubular bag package according to the invention during the opening process are described in the published international patent application WO 91/06488.

Die erfindungsgemäße Schlauchbeutelpackung wird in erster Linie als Packung für Lebensmittel wie Schokoladen oder Dauerbackwaren eingesetzt.The tubular bag pack according to the invention is primarily used as a pack for foods such as chocolates or baked goods.
