Abstract

PCT No. PCT/AT86/00062 Sec. 371 Date Jul. 8, 1987 Sec. 102(e) Date Jul. 8, 1987 PCT Filed Aug. 12, 1987 PCT Pub. No. WO87/02011 PCT Pub. Date Apr. 9, 1987.Gas-sealed pack for receiving pieces of a material such as chocolate tablettes. It consists of an envelope (9) of a flat and foldable material, having two edge regions (6, 6') inside which is located a detachable joining strip (7) to provide a sealed closure, preferably by cold sealing. These edge regions are folded back onto the upper surface of the envelope (9). The outside of the edge region (6'), which is applied to the top surface of the envelope (9), is linked at least on part of its surface with the surface of the envelope (9) preferably by means of a hot melting adhesive. The other edge region (6), which is not connected to the upper surface of the envelope (9), does not extend as far as the joining strip (7). A fold (3) is preferably arranged on this edge. The inner surfaces of the envelope are joined by cold sealing. Thus the pack is preferably designed in a tubular shape. To open the pack the edge region (6) is gripped at the fold (3) and pulled away from the edge region (6') while releasing the seal in the region of the joining strip (7).

Description

Schlauchbeutelpackung für stückiges Verpakkungsgut wie Schokolade mit einer aus einem flächigen, faltbaren Verpackungsmaterial gebildeten Hülle mit einer Längssiegelungsnaht, an der zwei streifenförmige Randbereiche des Verpakkungsmaterials innerhalb eines streifenförmigen Verbindungsbereichs an den Verpackungsmaterial-Innenseiten direkt durch eine lösbare Siegelungsverbindung miteinander verbunden sind, wobei diese Randbereiche der Längssiegelungsnaht auf die Packungshüllenoberfläche umgeschlagen sind und dabei an dem Randbereich, der nicht an der Packungshüllenoberfläche anliegt, der Verpackungsmaterialrand nicht bis an den streifenförmigen Verbindungsbereich heranreicht, sowie mit zwei zu dieser Längssiegelungsnaht senkrecht verlaufenden Quersiegelungsnähten.Tubular bag pack for lumpy packaging goods such as chocolate with a sleeve formed from a flat, foldable packaging material with a longitudinal sealing seam, on which two strip-shaped edge regions of the packaging material are connected to one another directly by a releasable sealing connection within a strip-shaped connecting region on the inside of the packaging material, these edge regions of the longitudinal sealing seam are folded over onto the surface of the packaging sleeve and the edge of the packaging material does not reach the edge of the packaging sleeve, as far as the strip-shaped connection area, and with two transverse sealing seams running perpendicular to this longitudinal sealing seam.

Eine Schlauchbeutelpackung dieser Art ist aus der GB-A-693 888 bekannt. Beim Öffnen dieser Packung, die als Käsepackung beschrieben ist, werden an einem Ende der Längssiegelungsnaht deren Randbereiche an den Kanten angefaßt und auseinandergezogen. Dabei wird ein Teilbereich der Längssiegelungsnaht und die zu diesem benachbarte Schlauchbeutel-Quersiegelungsnaht aufgetrennt und das Verpackungsmaterial von einem Ende des Käseblocks abgeschält. Zur Durchführung dieser Manipulation sind beide Hände erforderlich. Nach Abtrennen von einer oder mehreren Scheiben von dem freigelegten Käseblock-Ende kann der Rest-Käseblock wieder vollständig in das Verpackungsmaterial eingehüllt werden.A tubular bag pack of this type is known from GB-A-693 888. When this package, which is described as a cheese package, is opened, the edge regions of the longitudinal sealing seam are gripped and pulled apart at one end of the longitudinal sealing seam. A part of the longitudinal sealing seam and the adjacent tubular bag transverse sealing seam are separated and the packaging material is peeled off from one end of the block of cheese. Both hands are required to perform this manipulation. After one or more slices have been separated from the exposed end of the cheese block, the remaining cheese block can be completely encased in the packaging material.

Eine einfach zu öffnende Schlauchbeutelpakkung, die insbesondere zum Verpacken von Schokoladetafeln dient, ist ferner aus der DE-OS 24 58 462 bekannt. Die Längssiegelungsnaht liegt hier insbesondere an einer Teilungskerbe der Schokoladetafel an der dieser Kerbe abgewandten Rückseite der Packungshülle. Zum Öffnen der Packung wird die Schokoladetafel an dieser Teilungskerbe so abgeknickt, daß die Längssiegelungsnaht an der Außenseite des Knickes zu liegen kommt. Die beiden in der Längssiegelungsnaht miteinander verbundenen Verpackungsmaterial-Randbereiche werden unter Auftrennung der Siegelungsverbindung mit fortschreitendem Abknicken der Packung, von der Packungsinnenseite ausgehend, voneinander abgeschält und geben schließlich in der Packungshülle eine Öffnung frei.An easy-to-open tubular bag package, which is used in particular for packaging chocolate bars, is also known from DE-OS 24 58 462. The longitudinal sealing seam lies here in particular on a dividing notch of the chocolate bar on the rear side of the packaging envelope facing away from this notch. To open the package, the chocolate bar is bent at this division notch so that the longitudinal sealing seam comes to rest on the outside of the crease. The two packaging material edge areas connected to one another in the longitudinal sealing seam are peeled from one another while the packing connection is being broken open, starting from the inside of the package, and finally open up an opening in the packaging envelope.

Die in der genannten DE-OS beschriebene Packung wurde in den letzten Jahren in großem Umfang als Schokoladepackung benutzt. Bei dieser Packung muß jedoch, um ein sauberes Abknicken des Verpackungsgutes zu gewährleisten, die Längssiegelungsnaht praktsich immer an einer Teilungskerbe oder -stelle des Verpakkungsgutes liegen. Dies stellt eine nicht unwesentliche Einschränkung der Möglichkeiten für die Anordnung der Längssiegelungsnaht dar.The package described in the aforementioned DE-OS has been used on a large scale as a chocolate package in recent years. With this pack, however, in order to ensure a clean kinking of the packaged goods, the longitudinal sealing seam must practically always lie at a divisional notch or location of the packaged goods. This represents a not insignificant limitation of the possibilities for the arrangement of the longitudinal sealing seam.

Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, eine Schlauchbeutelpackung anzugeben, bei der die Längssiegelungsnaht unabhängig von der Lage einer Teilungskerbe oder -stelle des Verpackungsgutes, wie etwa die Teilungskerbe einer Schokoladetafel, angeordnet werden kann und die ohne Abknicken des Verpackungsgutes in einfacher Weise mit einer Hand zu öffnen ist.The invention, as characterized in the claims, achieves the object of specifying a tubular bag package in which the longitudinal sealing seam can be arranged independently of the position of a division notch or location of the packaged goods, such as the division notch of a chocolate bar, and which can be arranged without kinking the Packaging goods can be opened easily with one hand.

Die Erfindung wird nachstehend anhand der Figuren eingehend erläutert. Soweit in diesen Figuren ein Verpackungsmaterial im Schnitt gezeigt wird, ist es zum besseren Verständnis übertrieben dick dargestellt.The invention is explained in detail below with reference to the figures. As far as a packaging material is shown in section in these figures, it is shown exaggeratedly thick for better understanding.

Fig. 1 illustriert die Herstellung einer bevorzugten Ausführung der erfindungsgemäßen Schlauchbeutelpackung vor Ausbildung des Verpakkungsmaterialschlauches.1 illustrates the production of a preferred embodiment of the tubular bag pack according to the invention before the packaging material tube is formed.

In der Verpackungsmaschine wird zunächst an einer von der Rolle abgezogenen Verpackungsmaterialbahn 1, die einseitig mit einer gegebenenfalls im Profil angebrachten Kaltsiegelungsschicht versehen ist, an einem Rand 2 eine Falte 3 gebildet, wobei die im Bereich der Falte 3 aneinanderliegenden Verpackungsmaterial-Innenseiten durch Kaltsiegelung miteinander verbunden werden. Die so mit einer Rand-Falte 3 versehene in ihrer Längsrichtung (d.h. in Fig. 1 senkrecht zur Zeichnungsebene) bewegte Verpackungsmaterialbahn 1 wird nun in üblicher Weise zur Bildung eines Verpackungsmaterialschlauches um die nacheinander zugeführten Verpackungsgutstücke, z.B. Schokoladetafeln 4, in Richtung der Pfeile 5 umgeschlagen, wonach man die Randbereiche 6, 6' (Fig. 2) der Verpackungsmaterialbahn 1 zur Bildung einer Längssiegelungsnaht miteinander verbindet.In the packaging machine, a fold 3 is first formed on an edge 2 of a packaging material web 1 pulled off the roll, which is provided on one side with a cold sealing layer optionally attached in the profile, the inside of the packaging material lying against one another in the area of the fold 3 being connected to one another by cold sealing will. The packaging material web 1, which is provided with an edge fold 3 in its longitudinal direction (i.e. perpendicular to the plane of the drawing in FIG. 1), is now used in the usual way to form a packaging material tube around the successively supplied packaging items, e.g. Chocolate bars 4, folded over in the direction of the arrows 5, after which the edge regions 6, 6 '(FIG. 2) of the packaging material web 1 are connected to one another to form a longitudinal sealing seam.

Fig. 2 zeigt eine von dem Verpackungsmaterialschlauch umschlossene Schokoladetafel 4 in einer Teildarstellung im Schnitt. An der Längssiegelungsnaht erfolgt die Kaltsiegelverbindung der beiden Randbereiche 6, 6' über einen in Bahnlängsrichtung (d.h. in Fig. 2 in Richtung senkrecht zur Zeichnungsebene) verlaufenden streifenförmigen Verbindungsbereich 7.FIG. 2 shows a chocolate bar 4 enclosed by the packaging material tube in a partial representation in section. At the longitudinal sealing seam, the cold seal connection of the two edge regions 6, 6 'takes place via a strip-shaped connection region 7 running in the longitudinal direction of the web (i.e. in FIG. 2 in the direction perpendicular to the plane of the drawing).

Anschließend an die Herstellung des Verpakkungsmaterialschlauches wird bevorzugt an der Außenseite des Randbereiches 6' ein Heißschmelzkleber 8 (Hotmelt) aufgebracht und unmittelbar danach die beiden zur Längssiegelungsnaht miteinander verbundenen Randbereiche 6, 6' in Richtung des Pfeiles 10 auf die Packungshüllenoberfläche 9 umgeschlagen und dabei die mit dem Heißschmelzkleber versehene Außenseite des Randbereiches 6' vor Erstarrung des Schmelzklebers mit der Packungshüllenoberfläche 9 verklebt (siehe Fig. 3).Subsequent to the production of the packaging material tube, a hot-melt adhesive 8 (hot melt) is preferably applied to the outside of the edge region 6 'and immediately thereafter the two edge regions 6, 6' connected to one another for the longitudinal sealing seam are folded over in the direction of arrow 10 onto the packaging sleeve surface 9 and thereby the the outside of the edge area 6 'provided with the hot-melt adhesive is glued to the packaging envelope surface 9 before the hot-melt adhesive solidifies (see FIG. 3).

Der die Schokoladetafeln 4 umschließende Verpackungsmaterialschlauch wird nun jeweils zwischen zwei aufeinanderfolgenden Schokoladetafeln mit zwei parallel zueinander verlaufenden Quersiegelungsnähten 21 versehen und durch Trennschnitte zwischen diesen beiden Quersiegelungsnähten in Einzelschlauchpackungen unterteilt.The packaging material tube enclosing the chocolate bars 4 is now provided in each case between two successive chocolate bars with two transverse sealing seams 21 running parallel to one another and divided into individual tube packs by separating cuts between these two transverse sealing seams.

Die so hergestellte Schlauchbeutelpackung wird in Fig. 3 in einer Teildarstellung im Schnitt und in Fig. 4 in perspektivischer Darstellung gezeigt. Man erkennt die auf die Packungshüllenoberfläche 9 umgeschlagene und durch Klebung fixierte Längssiegelungsnaht mit der Falte 3 des Randbereiches 6, sowie eine der Quersiegelungsnähte 21, welche nun die Flossen 11 der Schlauchbeutelpackung bilden.The tubular pouch produced in this way is shown in Fig. 3 in a partial representation in section and in Fig. 4 in perspective. One recognizes the longitudinal sealing seam with the fold 3 of the edge region 6, which is folded over and fixed by gluing on the packaging envelope surface 9, as well as one of the transverse sealing seams 21, which now form the fins 11 of the tubular bag pack.

Das Öffnen der Packung sei nun anhand der Figuren 5 und 6 näher beschrieben, die - jeweils in einer Teildarstellung analog wie Fig. 3 - zwei verschiedene Phasen des Öffnungsvorganges zeigen. Zum Öffnen der Packung wird der Randbereich 6 an der Falte 3 angefaßt, in Richtung des Pfeiles 12 angehoben (Fig. 3) und weiter in Richtung des Pfeiles 12' bzw. 12" (Figuren 5 und 6) gezogen. Dabei wird, wie aus Fig. 5 zu erkennen ist, der Randbereich 6 unter Auftrennen der Siegelungsverbindung 7 der Längssiegelungsnaht vom Randbereich 6' abgeschält, bis schließlich (Fig. 6) die beiden Randbereiche 6 und 6' völlig voneinander getrennt sind. Dabei bildet sich mit zunehmendem Abziehen des Randbereiches 6 in Richtung des Pfeiles 12" eine sich zunehmend verbreiternde Öffnung 13 in der Packungshülle. Bei dem Öffnungsvorgang werden nach dem Auftrennen der Siegelungsverbindung 7 in der Längssiegelungsnaht - je nach Aufbau des Verpackungsmaterials oder der Höhe der Siegelnahtfestigkeit - im Bereich 14 (Fig. 4) die Quersiegelungsnähte 21 der Flossen 11 aufgeschält oder es reißt das Verpackungsmaterial in diesem Bereich 14 an diesen Flossen 11 ein.The opening of the package will now be described in more detail with reference to FIGS. 5 and 6, which - each in a partial representation analogous to FIG. 3 - show two different phases of the opening process. To open the pack, the edge area 6 is gripped at the fold 3, raised in the direction of the arrow 12 (FIG. 3) and pulled further in the direction of the arrow 12 'or 12 "(FIGS. 5 and 6) 5, the edge area 6 is peeled off from the edge area 6 'while separating the sealing connection 7 of the longitudinal sealing seam, until finally (FIG. 6) the two edge areas 6 and 6' are completely separated from one another 6 in the direction of arrow 12 "an increasingly widening opening 13 in the packaging envelope. During the opening process, after the sealing connection 7 has been separated in the longitudinal sealing seam - depending on the structure of the packaging material or the level of the sealing seam strength - the transverse sealing seams 21 of the fins 11 are peeled off in the region 14 (FIG. 4) or the packaging material tears in this region 14 these fins 11 a.

Bei der vorstehend beschriebenen Packung wird beispielsweise ein dreischichtig aufgebautes Verpackungsmaterial verwendet, wie es in Fig. 1 im vergrößerten Detailschnitt dargestellt ist. Dieses Verpackungsmaterial besteht - von der Packungsaußenseite ausgehend - aus einer 0.012 bis 0.015 mm starken Folie 17 aus biaxial gerecktem Polypropylen (OPP), einem gestrichenen Papier 18 einer Grammatur von 40 bis 60 g/ m2, einer 0.007 bis 0.009 mm starken Aluminiumfolie 19 und einer vorzugsweise im Profil aufgebrachten Kaltkleberbeschichtung 20 auf Latexbasis (2 bis 7 g/m2 Feststoff).In the packaging described above, for example, a three-layer packaging material is used, as shown in FIG. 1 in an enlarged detail section. Starting from the outside of the pack, this packaging material consists of a 0.012 to 0.015 mm thick film 17 made of biaxially oriented polypropylene (OPP), a coated paper 18 with a grammage of 40 to 60 g / m 2 , a 0.007 to 0.009 mm thick aluminum film 19 and a latex-based cold adhesive coating 20 preferably applied in the profile (2 to 7 g / m 2 solid).

Ein anderer vorteilhafter Verpackungsmaterialaufbau besteht aus einer 0.01 bis 0.015 mm starken OPP-Folie, an die sich zur Packungsinnenseite zu eine metallisierte OPP-Folie einer Stärke von 0.020 bis 0.025 mm oder eine metallisierte 0.012 bis 0.020 mm starke Folie aus Polyäthylenterephthalat (PETP) und daran die Kaltkleberbeschichtung anschließt.Another advantageous packaging material structure consists of a 0.01 to 0.015 mm thick OPP film, to which a metallized OPP film with a thickness of 0.020 to 0.025 mm or a metallized 0.012 to 0.020 mm thick film made of polyethylene terephthalate (PETP) and attached to the inside of the pack the cold adhesive coating follows.

Für die Herstellung einer relativ billigen Pakkung kann als Verpackungsmaterial vorteilhaft ein Verbund gewählt werden, der - von der Packungsaußenseite ausgehend - aus einer 0.007 bis 0.009 mm starken Aluminiumfolie, einem Papier einer Grammatur von 35 bis 60 g/ m2 und der Kaltkleberbeschichtung besteht.For the production of a relatively cheap package, a composite can advantageously be chosen as the packaging material, which - starting from the outside of the package - consists of a 0.007 to 0.009 mm thick aluminum foil, a paper with a grammage of 35 to 60 g / m 2 and the cold adhesive coating.

Fig. 7 zeigt nun in perspektivischer Darstellung eine Schlauchbeutelpackung in halbgeöffnetem Zustand. Diese Packung unterscheidet sich von der Packung gemäß Fig. 4, daß bei ihr die Außenseite des Randbereiches 6' mit der Packungshüllenoberfläche 9 nur innerhalb der mit 15 angedeuteten Bereiche an den Quersiegelungsnähten 21 der Flossen 11 z.B. durch Verklebung mittels eines punktförmig aufgebrachten Heißschmelzklebers 8 mit der Packungshüllenoberfläche 9 verbunden ist. Durch die Herstellung der Quersiegelungsnähte 21 wird die zwischen den beiden Randbereichen 6, 6' bestehende Längssiegelungsnaht straff gespannt, durch die Verklebung in den Bereichen 15 in diesem Zustand gehalten und dadurch über ihre ganze Länge in ihrer umgeschlagenen Lage fixiert.7 now shows a perspective view of a tubular bag pack in the half-opened state. This pack differs from the pack according to FIG. 4 in that the outside of the edge area 6 'with the pack casing surface 9 is only within the areas indicated at 15 on the transverse sealing seams 21 of the fins 11, e.g. is connected to the packaging casing surface 9 by gluing by means of a hot melt adhesive 8 applied in a punctiform manner. By producing the transverse sealing seams 21, the longitudinal sealing seam existing between the two edge regions 6, 6 'is tensioned, held in this state by the gluing in the regions 15 and thereby fixed in its folded position over its entire length.

Das Öffnen der Packung erfolgt dadurch, daß man das Ende 16 der Randbereich-Falte 3 anfaßt und in Richtung des Pfeiles 12'" abschält, wobei für ein vollständiges Öffnen vorteilhafterweise längs der Falte 3 ein- oder zweimal nachgegriffen wird. In Fig. 7 sind die abgeschälten Flächen der Längssiegelungsnaht 7 bzw. der Quersiegelungsnaht 21 einer Flosse 11 durch Punktierung angedeutet.The package is opened by grasping the end 16 of the edge area fold 3 and peeling it off in the direction of the arrow 12 '", with one or two steps advantageously advantageously being followed along the fold 3 for a complete opening the peeled surfaces of the longitudinal sealing seam 7 or the transverse sealing seam 21 of a fin 11 are indicated by puncturing.
