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

Packung zum Verpacken von stückigem VerpackungsgutPack for packaging piece goods
Technisches GebietTechnical field
Die Erfindung betrifft eine im wesentlichen gasdichte Packung zum Verpacken von stückigem, gegebenenfalls in mehrere Teilstücke unterteilbarem oder unterteiltem Verpackungsgut mit einer aus einem flächigen, faltbaren Verpackungsmaterial gebildeten Hülle, an welcher zwei Randbereiche des Verpackungsmaterials an den Verpackungsmaterial-Innenseiten innerhalb eines insbesondere streifenförmigen Verbindungsbereiches durch eine lösbare Versiegelung miteinander verbunden sind. Die erfindungsgemäßen Packungen sollen dabei vorzugsweise jedoch nicht ausschließlich als Schlauchbeutelpackungen ausgeführt sein. Die beiden durch eine solche lösbare Versiegelung miteinander verbundenen Randbereiche des Verpackungsmaterials bilden dann die als Finns bezeichnete Längssiegelungsnaht der Schlauchbeutelpackung.The invention relates to an essentially gas-tight package for packaging lumpy, possibly subdividable or subdivided packaging material with a sleeve formed from a flat, foldable packaging material, on which two edge regions of the packaging material on the inside of the packaging material within a particularly strip-shaped connection area by a releasable seal are interconnected. However, the packs according to the invention are preferably not designed exclusively as tubular bag packs. The two edge regions of the packaging material which are connected to one another by such a releasable seal then form the longitudinal sealing seam of the tubular bag package, referred to as Finns.
Stand der TechnikState of the art
Eine Schlauchbeutelpackung dieser Art, die insbesondere zum Verpacken von Schokoladetafeln dient, ist aus der DE-OS 24 58 462 bekannt. Die Längssiegelungsnaht liegt h i er i n sbesondere an e i ner Te i l ungskerbe der Schόko l adetafel an der dieser Kerbe abgewandten Rückseite der Pakkungshülle. Zum Öffnen der Packung wird die Schokoladetafei 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 Packungshül le eine Öffnung frei.A tubular bag pack of this type, which is used in particular for packaging chocolate bars, is known from DE-OS 24 58 462. The longitudinal sealing seam lies 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 edge areas of the packaging material connected to each other in the longitudinal sealing seam are peeled off from the inside of the package as the seal connection is broken, with progressive kinking of the package, and finally give in Packing sleeve has an opening.
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 Abkn i cken des Verpackungsgutes zu gewährl ei sten , d i e Längssiegelungsnaht praktisch immer an einer Teilungskerbe oder -stelle des Verpackungsgutes 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 snap off of the packaged goods, the longitudinal sealing seam must practically always lie at a division notch or location of the packaged goods. This represents a not insignificant limitation of the possibilities for the arrangement of the longitudinal sealing seam.
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt nun die Aufgabe zugrunde, eine Pakkung der eingangs genannten Art zu schaffen, bei der die Siegelungsnaht, in welcher die beiden Verpackungsmaterial-Randbereiche miteinander verbunden sind, unabhängig von der Lage einer Teilungskerbe oder -stelle des Verpakkungsgutes a ngeordnet werden kann und di e ohne Abkn i cken des Verpackungsgutes in einfacher Weise gegebenenfalls auch mit einer Hand zu öffnen ist.The invention is based on the object of creating a package of the type mentioned at the beginning, in which the sealing seam in which the two packaging material edge regions are connected to one another can be arranged independently of the position of a dividing notch or location of the package material and di e can easily be opened with one hand, if necessary, without breaking the packaged goods.
Die der Erfindung zugrunde liegende Aufgabe wird in der erfindungsgemäßen Packung gelöst, die dadurch gekennzeichnet ist, daß die in einen streifenförmigen Verbindungsbereich durch Versiegelung miteinander verbundenen Verpackungsmaterial-Randbereiche auf die Packungshüllenoberfläche umgeschlagen sind, wobei die Außenseite des an der Packungshüllenoberfläche anliegenden Randbereiches zumindest über einen Teil ihrer Oberfäche durch Verklebung mit der Packungshüllenoberflache verbunden ist, und daß zumindest an dem nicht mit der Packungshüllenoberfläche verklebten Randbereich der streifenförmige Verbindungsbereich sich nicht bis an den Verpackungsmaterialrand erstreckt. Dabei erfolgt die genannte Verklebung mit der Packungshüllenoberfläche vorteilhaft durch einen Heißschmelzkleber.The object on which the invention is based is achieved in the pack according to the invention, which is characterized in that the packaging material edge regions which are connected to one another by sealing in a strip-shaped connecting region are turned over onto the surface of the packaging envelope, the outside of the edge region lying against the surface of the packaging envelope at least over part their surface is connected by gluing to the packaging envelope surface, and that, at least at the edge region not glued to the packaging envelope surface, the strip-shaped connecting region does not extend to the edge of the packaging material. The above-mentioned bonding is carried out with the packaging envelope surface advantageously by a hot melt adhesive.
Nach einer vorteilhaften Ausgestaltung der Erfindung ist die erfindungsgemäße Packung eine Schlauchbeutelpackung, in welcher die durch eine Versiegelung miteinander verbundenen und auf die Packungshüllenoberfläche umgeschlagenen Verpackungsmaterial-Randbereiche die Schlauchbeutel-Längssiegelungsnaht bilden, und bei der die Außenseite des umgeschlagenen und an der Packungshüllenoberfläche anliegenden Randbereiches nur an den oder im Bereich der Quersiegelungsnähte(n) der Schlauchbeutelpackung durch Verklebung mit der Packungshüllenoberfläche verbunden ist.According to an advantageous embodiment of the invention, the package according to the invention is a tubular bag package, in which the packaging material edge areas connected to one another by a seal and folded over on the packaging sleeve surface form the longitudinal bag sealing seam, and in which the outside of the folded-over edge area lying against the packaging sleeve surface is only on the or in the area of the transverse sealing seams (s) of the tubular bag pack is connected to the surface of the pack casing by gluing.
Gemäß einer weiteren Ausgestaltung der erfindungsgemäßen Packung ist diese eine Schlauchbeutel packung mit durch Kaltsiegelung hergestellten Längs- und Quersiegelungsnähten.According to a further embodiment of the pack according to the invention, this is a tubular bag pack with longitudinal and transverse sealing seams produced by cold sealing.
In einer anderen vorteilhaften Ausgestaltung der erfindungsgemäßen Packung ist diese dadurch gekennzeichnet, daß in dem nicht mit der Packungshüllenoberfläche verklebten Randbereich zwischen dem streifenförmigen Verbindungsbereich und dem Verpackungsmaterialrand das Verpakkungsmaterial eine Falte bildet, in welcher die Verpakkungsmaterial-Innenseiten aneinander anliegen. Dabei sind diese Verpackungsmaterial-Innenseiten vorteilhaft durch Kaltsiegelung miteinander verbunden.In another advantageous embodiment of the package according to the invention, this is characterized in that in the edge region which is not glued to the surface of the package cover, between the strip-shaped connection region and the edge of the packaging material, the packaging material forms a fold in which the inside of the packaging material abuts one another. These inner sides of the packaging material are advantageously connected to one another by cold sealing.
Kurze Beschreibung der für die Erfindung relevanten Zeichnungen im Zusammenhang mit einem Weg zur Ausführung der Erfindung.Brief description of the drawings relevant to the invention in connection with a way of carrying out the invention.
Die Erfindung wird nachstehend anhand der Figuren einge hend erläutert. Soweit in diesen Figuren ein Verpackungsmaterial im Schnitt gezeigt wird, ist es zum besseren Verständnis übertrieben dick dargestellt.The invention is illustrated below with reference to the figures explained. Insofar 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 Packung in Form einer1 illustrates the production of a preferred embodiment of the pack according to the invention in the form of a
Schlauchbeutelpackung vor Ausbildung des Verpackungsmaterialschlauches.Tubular bag packing before forming the packaging material tube.
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 a packaging material web 1 pulled off the roll, which is provided on one side with a cold sealing layer optionally applied in the profile, at an edge 2, the inside of the packaging material lying against one another in the region of the fold 3 being connected to one another by cold sealing become. 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 Verpackungsmaterial schlauches 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 hose is preferably applied to the outside of the edge area 6 ', a hot melt adhesive 8 (hot melt) and immediately afterwards the two edge areas 6, 6' connected to each other for longitudinal sealing seam are turned in the direction of arrow 10 onto the packaging envelope surface 9 and the outside of the hot melt adhesive provided Edge area 6 '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 cross-sealing seams 21 running parallel to one another and divided into individual tube packs by separating cuts between these two cross-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 bag pack produced in this way is shown in FIG. 3 in a partial representation in section and in FIG. 4 in a perspective representation. 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 Längssiegelungs naht 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 Si ege l ungsverbi ndung 7 i n der Längss i ege l ungsnaht - j e 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 - in each case 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 grasped 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 region 6 can be seen by opening the sealing connection 7 of the longitudinal sealing seam is peeled off from the edge region 6 'until finally (FIG. 6) the two edge regions 6 and 6' are completely separated from one another. As the edge area 6 is increasingly pulled off in the direction of the arrow 12 ", an increasingly widening opening 13 is formed in the packaging envelope. During the opening process, after the sealing connection 7 has been separated, the longitudinal seam is - depending on the structure of the packaging material or the level of the sealing seam strength - in the area 14 (FIG. 4) the transverse sealing seams 21 of the fins 11 are peeled off or the packaging material in this area 14 tears on these fins 11.
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 case of 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 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 connects.
Für die Herstellung einer relativ billigen Packung 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.A composite can advantageously be chosen as the packaging material for producing a relatively inexpensive package which - starting from the outside of the pack - consists of 0.007 to 0.009 mm aluminum foil, paper with a grammage of 35 to 60 g / m 2 and the cold adhesive coating.

Diese Packung unterscheidet sich von der Packung gemäß Fig. 4, daß be i i hr d i e Außen se i te des Rand bere i ches 6 ' m i t 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 on the outer side of the edge area 6 'with the pack casing surface 9 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 touching the end 16 of the edge area fold 3 and peeling it off in the direction of the arrow 12 ″ ″, advantageously being followed once or twice along the fold 3 for a complete opening. In Fig. 7, the peeled surfaces of the longitudinal sealing seam 7 or the transverse sealing seam 21 of a fin 11 are indicated by puncturing.
