Abstract

The packing comprises an envelope provided with a tearing tongue (7) and comprised of a flexible and foldable material. This envelope comprises a double thickness section, wherein the two layers (4, 5) are bound one against the other and where the free end of the tearing tongue is located. Both layers and the tongue may be secured together in a gas tight relationship. To facilitate the tearing of the tongue (7), a zone of the layer (5) of the envelope which is opposite to the layer (4) at the location where it is provided with the tongue (7) is delimited by weakening lines (12) so as to be easily detached from the rest of the envelope during the tearing of the tongue. For manufacturing bags, the tearing tongue (7) is arranged preferably along the length of the band of packing material. A support layer having weakening lines provided by cutting is joined with a tight, non-perforated layer of packing material.

Description

Die Erfindung bezieht sich auf eine Schlauchbeutelpackung zum Verpacken von festem Verpackungsgut, die aus einer aus einem flächigen, flexiblen und faltbaren Verpackungsmaterial gebildeten Hülle besteht, wobei das Verpackungsmaterial an der Hülleninnenseite eine Siegelungsschicht aufweist und die Hülle einen zumindest nahezu quaderförmigen Raum umschließt, dessen kleinste Seitenkante zumindest nahezu senkrecht zu den Ebenen der zwei sich bei der Schlauchbeutelherstellung bildenden Flossen verläuft. Sie bezieht sich ferner auf ein vorteilhaftes Verfahren zur Herstellung einer solchen Schlauchbeutelpackung.The invention relates to a tubular bag pack for packing solid packaging goods, which consists of a casing formed from a flat, flexible and foldable packaging material, the packaging material having a sealing layer on the inside of the casing and the casing enclosing an at least almost cuboidal space, the smallest side edge of which at least almost perpendicular to the planes of the two fins that are formed during the manufacture of tubular bags. It also relates to an advantageous method for producing such a tubular bag pack.

Packungen zum Verpacken von festem Verpackungsgut mit einer Hülle aus einem flächigen Verpackungsmaterial, die einen etwa quaderförmigen Raum umschließt, dessen kleinste Seitenkante klein ist gegenüber den zwei anderen Seitenkanten, also z.B. Schokoladepackungen bzw.Packungen für anderes tafelförmiges Verpackungsgut werden derzeit in überwiegendem Ausmaß in Form von Einschlagverpackungen ausgeführt.Packs for packing solid packaged goods with a sleeve made of a flat packaging material, which encloses an approximately cuboidal space, the smallest side edge of which is small compared to the two other side edges, e.g. Chocolate packs or packs for other tabular packaging goods are currently predominantly carried out in the form of wrapping packaging.

Der maschinentechnische Aufwand bei der Herstellung von Einschlagverpackungen ist besonders hoch, der Ausstoß der Verpackungsmaschinen mit höchstens etwa 80 Stk/min relativ klein. Gasdichtheit der Verpackungsmaterial-Hülle, die in zunehmendem Maße für die Erreichung einer Verlängerung der Gebrauchsdauer des Verpackungsgutes gefordert wird, kann bei Einschlagverpackungen auf einfache Weise nicht realisiert werden.The amount of mechanical engineering involved in the production of wrapping packaging is particularly high, and the output of the packaging machines is relatively low at a maximum of about 80 pieces / min. Gas tightness of the packaging material envelope, which is increasingly required to achieve an extension of the useful life of the packaging goods, cannot be easily achieved with wrapping packaging.

Es sind nun aber auch Schlauchbeutelpackungen für Schokoladetafeln bekannt, deren Herstellung weniger aufwendig ist und mit wesentlich größerem Ausstoß(nämlich in der Größenordnung von 150 bis 350 Stk/min) erfolgen kann als bei Einschlagverpackungen. Solche Schlauchbeutelpackungen können gasdicht ausgeführt werden.However, tubular bag packs for chocolate bars are now also known, the production of which is less complex and can be carried out with a significantly greater output (namely in the order of 150 to 350 pieces / min) than with wrapping packs. Such tubular bag packs can be made gastight.

Die Gründe, die einer beschleunigten Einführung von Schlauchbeutelpackungen für Schokoladepackungen im Wege stehen, scheinen einerseits darin zu liegen, daß die Form der Schlauchbeutelpackung mit dem an seinen beiden Enden wegstehenden Flossen nicht der Form entspricht, die der Käufer traditionell von einer Schokoladepackung erwartet. Außerdem stören die abstehenden Flossen bei der Distribution. So werden solche Schlauchbeutel-Schokoladepackungen lose in einem Überkarton verpackt, was gegenüber der kompakten Art der Stapelung in Sammelpackungen, wie sie bei Ein- schlagpackungen möglich ist, Nachteile mit sich bringt. Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, eine Schlauchbeutelpackung der eingangs der Beschreibung genannten Art, sowie ein vorteilhaftes Verfahren zu ihrer Herstellung anzugeben, wobei diese erfindungsgemäßen Schlauchbeutelpackungen ein Aussehen ähnlich dem von Einschlagpackungen haben sollen und in derselben vorteilhaften Weise wie Einschlagverpackungen in Sammelpackungen zusammengefaßt werden können.The reasons that stand in the way of an accelerated introduction of tubular bag packs for chocolate packs appear to be, on the one hand, that the shape of the tubular bag pack with the fins sticking out at both ends does not correspond to the shape that the buyer traditionally expects from a chocolate pack. In addition, the protruding fins interfere with the distribution. So those flute-shaped chocolate packages are loose in an over carton, which brings disadvantages compared to the compact type of stacking in multi-packs, as is possible with inputs schla g packages. The invention seeks to remedy this. The invention, as characterized in the claims solves the problem of a tubular bag p ackung of specifying the beginning of the type mentioned description, as well as an advantageous process for their preparation, an appearance of said tubular bag according to the invention ackungen p similar to to have of wrapping packs and can be grouped together in the same advantageous manner as wrapping packages.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert. Es zeigt:

  • Figur 1 ein schematisches Übersichtsbild für ein Verfahren zur Herstellung einer Schlauchbeutelpackung für Schokolade und Figur 2 die durch dieses Verfahren hergestellte Packung.
The invention is explained in more detail below with the aid of drawings which illustrate only one embodiment. It shows:
  • Figure 1 is a schematic overview diagram for a method of manufacturing a tubular bag p ackung for chocolate and Figure 2 the package made by this process.

Bei diesem Verfahren wird als Verpackungsmaterial ein flexibles, flächiges Verbundmaterial eingesetzt, bei dessen Herstellung von einem gestrichenen Papier (Flächengewicht etwa 50 g/m2) ausgegangen wird, welches den mechanisch stärksten Teil des Verbundmaterials ausmacht. Dieses Papier wird nun längs den Stellen, an denen später an den Packungen Schwächungslinien vorliegen müssen, über den größten Teil dieser Schwächungslinien mit Durchstanzungen und in demselben Arbeitsgang an seiner hüllenaußenseitigen Oberfläche mit einem dekorativen Druck versehen. Die bedruckte und mit Durchstanzungen versehene Papierbahn wird an ihrer Rückseite mit Hilfe eines Naßklebers mit einem Kleberauftrag von etwa 2 g/m2 (Festkörper) mit einer Aluminiumfolie der Type "Alu 99,0 weich" und einer Stärke von 0,012 mm kaschiert. Der so hergestellte Teilverbund wird dann auf seiner Rückseite, d.h. also auf der Aluminiumfolienoberfläche, mit einem Primer-Auftrag (Flächengewicht 1,5 g/m2) und danach mit einer Kaltkleberbeschichtung (10 bis 15 g/m Flächengewicht) versehen. Schließlich wird auf die Kaltkleberbeschichtung noch ein in Längsrichtung der Verbundmaterialbahn durchlaufendes Aufreißband aufgehracht, zu dessen beiden Seiten und parallel zu ihm die Papierschicht des Verbundmaterials ebenfalls Schwächungslinien aufweist.In this process, a flexible, flat composite material is used as the packaging material, the production of which is based on coated paper (basis weight about 50 g / m 2 ), which makes up the mechanically strongest part of the composite material. This paper is now provided with punched holes along the places where weakening lines must later be present on the packs, over most of these weakening lines and in the same operation with a decorative print on its outer surface. The printed and punched paper web is laminated on the back with the aid of a wet adhesive with an adhesive application of about 2 g / m 2 (solid) with an aluminum foil of the type "Alu 99.0 soft" and a thickness of 0.012 mm. The part of the composite so produced is then so that on the aluminum foil surface with a primer application (basis weight of 1.5 g / m 2) and then g with a Kaltkleberbeschichtun (10 to 15 g / m basis weight) provided on its back side. Finally, a tear strip running in the longitudinal direction of the composite material web is applied to the cold adhesive coating, on both sides of which and parallel to it the paper layer of the composite material likewise has lines of weakness.

Fig.l zeigt auf der linken Seite die Zuführung der zu verpackenden Schokoladetafeln 1, die einzeln in Richtung des ) Pfeiles 2 einer Verpackungsmaschine zugeführt werden. In dieser bewegen sich die Schokoladetafeln 1 nun in einer Richtung 3 senkrecht zu ihrer größten Seitenkante. Die Verbundmaterialbahn 4, die von einer Rolle 5 abgezogen und bei der Stelle 6 mit dem zugeführten Aufreißband 7 versehen wird, wird um die Schokoladetafeln 1 gefaltet und mittels einer (in Fig.1 nicht zu erkennenden ) an der Unterseite der Verpackungsmaschine angebrachten Siegelungsvorrichtung mit einer Längssiegelungsnaht versehen. Der so geformte, die einzelnen Schokoladetafeln umhüllende Verbundmaterialschlauch 8 wird nun mit Hilfe von rotierenden Siegelungsbacken 9 in Einzelpackungen 10 unterteilt, die dabei zusätzlich mittels eines an den Siegelungsbacken 9 angebrachten Schneidewerkzeuges voneinander getrennt werden.Fig.l shows on the left side the supply of the chocolate bars 1 to be packaged, which are individually fed in the direction of the arrow 2 to a packaging machine. In this the chocolate bars 1 now move in a direction 3 perpendicular to their largest side edge. The composite material web 4 drawn off a roll 5 and is provided at the point 6 with the tear tape 7 supplied, is folded around the chocolate bars 1 and provided with a longitudinal sealing seam by means of a sealing device (not shown in FIG. 1) attached to the underside of the packaging machine. The thus formed, the individual chocolate bars enveloping composite material tube 8 is now divided by means of rotating sealing jaws 9 into individual packs 10, which are additionally separated from one another by means of a cutting tool attached to the sealing jaws 9.

Die so hergestellten Einzelpackungen 10 werden darauf nacheinander in vertikaler Richtung durch eine kastenförmige Düse 11 geschoben.The individual packs 10 thus produced are then pushed one after the other in the vertical direction through a box-shaped nozzle 11.

Der Innenraum der Düse 11 wird an zwei einander gegenüberliegenden Seiten von Zylindermantelflächen 12 begrenzt (womit die allgemeinste Bedeutung des Wortes und nicht Kreiszvlindermantelflächen gemeint sind), derart, daß dieser Raum eine sich mit fortschreitendem Bewegungsweg in Richtung des Pfeiles 13 verringernde Querschnittsbreite aufweist, wodurch - wie an den Stellen 14 angedeutet - beim Durchschieben der Einzelpackungen 10 durch die Düse 11 die durch die Quersiegelungsnähte gebildeten abstehenden Verpackungsmaterial-Flossen 15 auf die Hüllenoberfläche, von der sie ausgehen, umgeschlagen werden.The interior of the nozzle 11 is delimited on two opposite sides by cylinder jacket surfaces 12 (which means the most general meaning of the word and not circular cylinder jacket surfaces), in such a way that this space has a cross-sectional width which decreases with the progressive movement path in the direction of the arrow 13, as a result of which - as indicated at points 14 - when pushing the individual packs 10 through the nozzle 11, the protruding packaging material fins 15 formed by the transverse sealing seams are turned over onto the surface of the casing from which they originate.

Die fertigen Einzelpackungen 16 treten dann aufeinandergestapelt aus dem oberen Ausgang der Düse 11 aus und können, wie bei 17 angedeutet, stapelweise zwecks einer weiteren Verpackung abgeführt werden.The finished individual packs 16 then emerge stacked on top of one another from the upper outlet of the nozzle 11 and, as indicated at 17, can be removed in batches for the purpose of further packaging.

Gemäß einer anderen Variante des erfindungsgemäßen Verfahrens können die beiden den Raum der Düse an zwei einander gegenüberliegenden Seiten begrenzenden Zylidermantelflächen, z.B. in Form von umlaufenden Bändern, beweglich ausgeführt sein, welche der Bewegung der Einzelpackungen durch die Düse zumindest zum größten Teil folgen, wodurch eine Reibung zwischen der Düseninnenwand und den Einzelpackungen zumindest weitgehend vermieden werden kann.According to another variant of the method according to the invention, the two cylindrical jacket surfaces delimiting the space of the nozzle on two opposite sides, e.g. in the form of revolving belts that can be moved, which at least for the most part follow the movement of the individual packs through the nozzle, as a result of which friction between the inner wall of the nozzle and the individual packs can be at least largely avoided.

Gemäß einer Verfahrensvariante werden die Verpackungsmaterial-Flossen 15 an den Hüllenoberflächenbereichen, auf die sie umgeschlagen werden, vorteilhaft durch eine Klebung fixiert.According to a variant of the method, the packaging material fins 15 are advantageously fixed to the envelope surface areas to which they are turned over by an adhesive.

Dazu kann man z.B. an der Stelle 18 (siehe Fig.1) an der Unterseite der Verpackungsmaschine eine Vorrichtung anbringen, mit deren Hilfe ein Heißkleberauftrag in Form von mehreren Tupfen auf die Unterseiten der abstehenden Verpackungsmaterial-Flossen 15 aufgebracht wird. Die dazu erforderliche Vorrichtung weist neben einer Einrichtung zur Aufbereitung und Abgabe von geschmolzenem Heißkleber eine Reihe von Düsen auf, die für den Kleberauftrag jeweils in die Nähe der zu verklebenden Oberfläche gebracht werden und aus denen dann eine bestimmte Menge Heißkleber in Form von Kleber-Tupfen auf diese Oberfläche, d.h. in vorliegendem Fall also auf die Unterseiten der Verpackungsmaterial-Flossen 15, aufgebracht wird.This can be done, for example, mount a device on the underside of the packaging machine with the aid of a hot melt adhesive application in the form of several Tu p fen is applied to the undersides of the protruding packaging material fins 15 at the point 18 (see Fig.1). In addition to a device for processing and dispensing molten hot melt adhesive, the device required for this purpose has a number of nozzles which are brought near the surface to be bonded for the adhesive application and from which then a certain amount of hot melt adhesive in the form of adhesive spots this surface, ie in the present case on the undersides of the packaging material fins 15, is applied.

Die in Tupfenform aufgebrachte Klebermenge erstarrt, behält aber noch so lange ihre Klebefähigkeit, bis die I Verpackungsmaterial-Flossen 15 in der kastenförmigen Düse 11 an den Hüllenbereichen der Packung, von der sie ausgehen, umgeschlagen und dabei festgeklebt werden.The amount of adhesive applied in the form of dots solidifies, but retains its adhesive capacity until the packaging material fins 15 in the box-shaped nozzle 11 are turned over at the envelope areas of the package from which they originate, and are thereby adhered.

Die durch das vorstehend beschriebene Verfahren hergestellte Schlauchbeutelpackung ist schematisch in Fig.2 dargestellt.The tubular bag pack produced by the method described above is shown schematically in FIG.

An der Oberseite der Packung erkennt man das Aufreißband 7, zu dessen beiden Seiten - wie in der Beschreibung des Herstellungsverfahren bereits erwähnt - Schwächungslinien 19 vorgesehen sind. Neben und parallel zu dem Aufreißband 7 verläuft die umgelegte Verpackungsmaterial-Finne 20, welche bei der Herstellung der Längssiegelungsnaht zur Bildung des Verbundmaterialschlauches 8 (siehe Fig.1) entsteht.At the top of the pack one can see the tear tape 7, on whose two sides - as already mentioned in the description of the manufacturing process - weakening lines 19 are provided. The folded-over packaging material fin 20, which arises during the production of the longitudinal sealing seam to form the composite material tube 8 (see FIG. 1), runs next to and parallel to the tear tape 7.

Aufreißband 7 und Verpackungsmaterial-Finne 20 verlaufen senkrecht zur längsten Seitenkante 21 der Packung. Die an den Quersiegelungsnähten entstehenden Verpackungsmaterial-Flossen 15 sind auf die Hüllenoberflächenebene 22, von der sie ausgehen, beide in dieselbe Richtung umgeschlagen.Tear tape 7 and packaging material fin 20 run perpendicular to the longest side edge 21 of the package. The packaging material fins 15 which arise at the transverse sealing seams have both turned over in the same direction on the envelope surface plane 22 from which they originate.
