Abstract

PCT No. PCT/AT87/00041 Sec. 371 Date Apr. 21, 1988 Sec. 102(e) Date Apr. 21, 1988 PCT Filed Jul. 22, 1987 PCT Pub. No. WO88/00562 PCT Pub. Date Jan. 28, 1988.In an easy-to-open chocolate package, the wrapper has two areas (2, 3,23', 24') where the packing material is folded in two, made of two layers of packing material sealed together by their inner side, lying on an essentially even upper surface of the wrapper and laterally enclosing a tearing up zone (18, 26) of the wrapper, so that when the package is torn open the wrapper is opened up in these areas. In an embodiment as a cylindrical bag, the tearing up zones (18, 26) extend until the free edge (11, 11') of a fin (10, 10') by which the tearing up zone (18, 26) is held when tearing the package open. These areas (2, 3) where the packing material is folded in two preferably take the form of folds, one flank of which is provided with a break line (4) of the packing material, along which the material is torn when the package is opened. In another version, the areas (23', 24') where the material is folded in two are produced by cutting the edges of folds (23, 24) previously formed in the packing material; the wrapper is then opened by peeling off the seals of these folded areas (23', 24').

Description

Packung zum Verpacken von stückigem Verpackungsgut, sowie Verfahren zum Herstellen solcher Packungen. Pack for packaging lumpy packaged goods, and process for producing such packs.
Technisches GebietTechnical field
Die Erfindung betrifft eine im wesentlichen gasdichte Packung zum Verpacken von stückigem, insbesondere in mehrere Teilstücke unterteiltem oder unterteilbarem Verpackungsgut mit einer aus einem flächigen, faltbaren Verpackungsmaterial gebildeten Hülle, die zumindest zwei streifenförmige Dopplungsbereiche des Verpackungsmaterials aufweist, in welchen jeweils die beiden den Dopplungsbereich bildenden Verpackungsmaterial-Lagen an ihren Verpackungsmaterial-Innenseiten über einen streifenförmigen Siegelungsbereich miteinander verbunden sind, wobei die Packungshülle dazu bestimmt ist, zu ihrer Öffnung an zumindest einem dieser Dopplungsbereiche aufgetrennt zu werden. Die erfindungsgemäßen Packungen sollen dabei vorzugsweise jedoch nicht ausschließlich als Schlauchbeutelpackungen ausgeführt sein. Die Erfindung betrifft ferner vorteilhafte Verfahren zum Herstellen der erfindungsgemäßen Packung.The invention relates to an essentially gas-tight package for packaging lumpy packaging goods, in particular divided or subdividable into several parts, with a casing formed from a flat, foldable packaging material, which has at least two strip-shaped doubling areas of the packaging material, in each of which the two packaging materials forming the doubling area -Layers are connected to each other on the inside of their packaging material by means of a strip-shaped sealing area, the packaging sleeve being intended to be opened at least in one of these doubling areas in order to open it. However, the packs according to the invention are preferably not designed exclusively as tubular bag packs. The invention further relates to advantageous methods for producing the pack according to the invention.
Stand der TechnikState of the art
Eine Packung dieser Art ist in der europäischen Patentanmeldung 85104700.1 (Veröff.Nr. 0152291) anhand von Fig. 3 beschrieben. Diese Packung, die eine Schlauchbeutelpackung zum Verpacken von Schokolade ist, hat eine Falte, die von der Packungshülle im Bereich einer Schokoladeriegel-Teilungskerbe ausgeht und die innerhalb des streifenförmigen Bereiches, in welchem die beiden Falten-Flanken durch eine Siegelung miteinander verbunden sind, längs einer Schwächungslinie mehrere voneinander getrennte Iinienförmige Durchstanzungen aufweist. Zum öffnen der Packung wird diese zu beiden Seiten der Falte mit den Händen angefaßt und um eine parallel zur Faltenlängserstreckung verlaufende Achse bei gleichzeitigem Durchbrechen der Schokoladetafel abgeknickt und dabei die Siegelungs-Verbindung der Falten-Flanken aufgeschält, bis die Durchstanzungen freigelegt sind, wonach die zwischen den Durchstanzungen bestehenden Materialbrücken durchgerissen werden und sich eine schlitzförmige öffnung auftut, aus der dann Teile der Schokoladetafel entnommen werden können. Durch dieses Abknicken wird während des Öffnungsvorganges die Packungshülle besonders im Bereich der erzeugten Öffnung und des entnommenen Verpackungsgutes mehr oder weniger zerknüllt, was ihsbesondere dann ungewünscht ist, wenn die Packung in nur teilweise geleertem Zustand einige Zeit aufbewahrt werden soll. Diese Packung kann außerdem nur für relativ harte Verpackungsgüter eingesetzt werden.A pack of this type is described in European patent application 85104700.1 (publication no. 0152291) with reference to FIG. 3. This package, which is a tubular bag package for packaging chocolate, has a fold that starts from the packaging envelope in the area of a chocolate bar dividing notch and that runs along one within the strip-shaped area in which the two fold flanks are connected to one another by a seal Line of weakness several from each other has separate linear punchings. To open the package, grasp it on both sides of the fold with your hands and kink it about an axis parallel to the longitudinal extension of the fold while breaking through the chocolate bar and peel the sealing connection of the fold sides until the punched holes are exposed, after which the between existing material bridges are torn through and a slit-shaped opening opens from which parts of the chocolate bar can then be removed. As a result of this kinking, the packaging envelope is crumpled to a greater or lesser extent, particularly in the area of the opening created and the packaging material removed, which is particularly undesirable if the package is to be kept in a partially emptied state for some time. This pack can also only be used for relatively hard packaging goods.
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt nun zunächst die Aufgabe zugrunde, eine Packung der eingangs genannten Art anzugeben, die auf einfache Weise geöffnet werden kann, derart, daß beim öffnen und der Entnahme vom Verpackungsgut die ursprüngliche Form der Packung nicht wesentlich geändert: wird und die auch für relativ weiche Verpackungsgüter eingesetzt werden kann.The invention is first of all the object of specifying a pack of the type mentioned at the outset, which can be opened in a simple manner in such a way that the original form of the pack is not substantially changed when the packaged goods are opened and removed: and also for relatively soft packaging goods can be used.
Diese Aufgabe wird in der erfindungsgemäßen Packung gelöst, die dadurch gekennzeichnet ist, daß bei einer Pakkung mit einem zumindest ebenen Oberflächenbereich die Packungshülle an diesem Oberflächenbereich - im Abstand voneinander angeordnet - zwei streifenförmige Dopplungs bereiche aufweist, in welchen jeweils in an sich bekannter Weise die beiden den Dopplungsbereich bildenden Verpackungsmaterial-Lagen an ihren Verpackungsmaterial-Innenseiten über einen streifenförmigen Siegelungsbereich miteinander verbunden sind, die nun aber erfindungsgemäß einen Aufreißbereich der Packungshülle seitlich einfassen. Dabei können diese beiden Falten vorteilhaft in der Nähe von zwei einander gegenüberliegenden Rändern des ebenen Oberflächenbereiehes der Packung angeordnet sein.This object is achieved in the pack according to the invention, which is characterized in that, in the case of a pack having an at least flat surface area, the packing envelope on this surface area — arranged at a distance from one another — has two strip-shaped doublings areas in which the two layers of packaging material forming the doubling area are connected to one another on their inside of the packaging material via a strip-shaped sealing area, which, however, according to the invention now enclose a tear-open area of the packaging envelope laterally. These two folds can advantageously be arranged in the vicinity of two mutually opposite edges of the flat surface area of the pack.
Nach einer vorteilhaften Ausgestaltung der erfindungsgemäßen Packung ist sie dadurch gekennzeichnet, daß der Aufreißbereich durch äußere Ränder der den Aufreißbereich einfassenden Dopplungsbereiche seitlich begrenzt ist.According to an advantageous embodiment of the package according to the invention, it is characterized in that the tear-open area is laterally delimited by outer edges of the double areas surrounding the tear-open area.
Gemäß einer anderen vorteilhaften Ausgestaltung der Erfindung ist die erfindungsgemäße Packung dadurch gekennzeichnet, daß der Aufreißbereich durch linienförmige Sollbruchstellen im Verpackungsmaterial seitlich begrenzt ist, die jeweils in den außen liegenden Lagen der den Aufreißbereich einfassenden Dopplungsbereiche und zwar jeweils innerhalb von deren streifenförmigen Siegelungsbereichen angeordnet sind.According to another advantageous embodiment of the invention, the package according to the invention is characterized in that the tear-open area is laterally delimited by line-shaped predetermined breaking points in the packaging material, each of which is arranged in the outer layers of the double areas enclosing the tear-open area and in each case within their strip-shaped sealing areas.
In einer weiteren vorteilhaften Ausgestaltung der erfindungsgemäßen Packung ist diese dadurch gekennzeichnet, daß die Dopplungsbereiche jeweils in Richtung von der Aufreißbereichsmiite weg auf die Packungsoberfläche umgelegt sind. Dabei sind die an der Packungsoberfläche anliegenden Verpackungsmaterial-Lagen der umgelegten Dopplungsbereiche vorteilhaft zumindest über einen Teil ihrer Oberflächen mit der Packungsoberfläche durch Verklebung oder Verschweißung verbunden. Gemäß einer anderen vorteilhaften Ausgestaltung der Erfindung ist die erfindungsgemäße Packung dadurch gekennzeichnet, daß die Packung eine Schlauchbeutelpackung mit einer Längssiegelungsnaht und zwei die Flossen der Pakkung bildenden Quersiegelungsnähten ist, wobei die beiden den Aufreißbereich seitlich einfassenden Dopplungsbereiche parallel zur Längssiegelungsnaht verlaufen und den Siegelungsbereich von zumindest einer der Quersiegelungsnähte kreuzen, und wobei der Aufreißbereich durch den freien Rand von zumindest einer der Flossen begrenzt ist. Dabei reicht vorteilhaft an einer Flosse der Pakkung, deren freier Rand den Aufreißbereich begrenzt, der Siegelungsbereich der Quersiegelungsnaht zumindest im Bereich zwischen den Enden der beiden Dopplungsbereiche nicht bis an den freien Flossenrand heran.In a further advantageous embodiment of the pack according to the invention, it is characterized in that the doubling areas are each folded over in the direction away from the tear-open area on the pack surface. The layers of packaging material lying on the packaging surface of the folded double regions are advantageously connected to the packaging surface at least over part of their surfaces by gluing or welding. According to another advantageous embodiment of the invention, the package according to the invention is characterized in that the package is a tubular bag package with a longitudinal sealing seam and two transverse sealing seams forming the fins of the package, the two doubling regions bordering the tear area laterally parallel to the longitudinal sealing seam and the sealing area of at least one of the transverse sealing seams cross, and the tear area being delimited by the free edge of at least one of the fins. In this case, advantageously on a fin of the package, the free edge of which limits the tear-open area, the sealing area of the transverse sealing seam does not reach the free fin edge, at least in the area between the ends of the two doubling areas.
Nach einer letzten vorteilhaften Ausgestaltung der er¬findungsgenräßen Packung ist diese dadurch gekennzeichnet, daß die Dopplungsbereiche, an denen linienförmige Sollbruchstellen im Verpackungsmaterial seitliche Begrenzungen des Aufreißbereiches bilden, an der Packungsoberfläche ausgebildete Verpackungsmaterial-Falten sind.According to a last advantageous embodiment of the pack according to the invention, this is characterized in that the doubling areas, at which linear break points in the packaging material form lateral boundaries of the tear-open area, are packaging material folds formed on the packaging surface.
Die Erfindung betrifft ferner zwei vorteilhafte Verfahren zum Herstellen der erfindungsgemäßen Packung.The invention further relates to two advantageous methods for producing the pack according to the invention.
Dabei ist ein erstes solchen Verfahren dadurch gekennzeichnet, daß man im Verpackungsmaterial im Abstand voneinander zwei Falten ausbildet, wobei deren Flanken jeweils durch Siegelung in einem streifenförmigen Siegelungsbereich miteinander verbunden werden, daß an den Faltenkanten jeweils ein in Faltenlängserstreckung verlaufender streifenförmiger Bereich der Falte abgeschnitten wird, so daß das restliche Material der Falten Dopp lungsbereiche des Verpackungsmaterials bildet, deren Verpackungsmaterial-Lagen äußere Ränder aufweisen, die bei der herzustellenden Packung einen Aufreißbereich des Verpackungsmaterials seitlich begrenzen, daß die beiden Dopplungsbereiche dann auf die Packungsoberfläche umgelegt werden und daß danach aus dem so vorbereiteten Verpackungsmaterial die Packungshülle hergestellt wird.A first method of this type is characterized in that two folds are formed at a distance from one another in the packaging material, the flanks of which are each connected to one another by sealing in a strip-shaped sealing region, in that a strip-shaped region of the fold extending in the longitudinal direction of the fold is cut off at the fold edges, so the remaining material of the folds double Formation areas of the packaging material, the packaging material layers have outer edges that laterally limit a tear-open area of the packaging material in the pack to be produced, that the two doubling areas are then folded over onto the packaging surface and that the packaging envelope is then produced from the packaging material thus prepared.
Ein zweites erfindungsgemäßes Verfahren ist hingegen dadurch gekennzeichnet, daß im Verpackungsmaterial zwei im Abstand voneinander verlaufende linienförmige Sollbruchstellen vorgesehen werden, daß man an diesen Sollbruchstellen jeweils im Verpackungsmaterial eine Falte ausbildet, wobei deren Flanken jeweils durch Siegelung in einem streifenförmigen Siegelungsbereich miteinander verbunden werden, so daß die Sollbruchstellen jeweils an einer der Flanken der Falten innerhalb des streifenförmigen Siegelungsbereiches zu liegen kommen, daß die beiden Falten auf die Packungshülle umgelegt werden und daß danach aus dem so vorbereiteten Verpackungsmaterial die Packungshülle hergestellt wird.A second method according to the invention, on the other hand, is characterized in that two linear predetermined breaking points spaced apart from one another are provided in the packaging material, that a fold is formed in the packaging material at each of these predetermined breaking points, the flanks of which are connected to one another by sealing in a strip-shaped sealing area, so that the predetermined breaking points each come to rest on one of the flanks of the folds within the strip-shaped sealing area, that the two folds are folded over onto the packaging envelope and that the packaging envelope is then produced from the packaging material thus prepared.
Kurze Beschreibung der Zeichnungen im Zusammenhang mit zwei vorteilhaften Wegen zur Ausführung der ErfindungBrief description of the drawings in connection with two advantageous ways of carrying out the invention
Die Erfindung wird nachstehend anhand der Figuren eingehend erläutert. Soweit in diesen Figuren ein Verpakkungsmaterial im Schnitt gezeigt wird, ist es zum besseren Verständnis übertrieben dick dargestellt.The invention is explained in detail below with reference to the figures. Insofar as a packaging material is shown in section in these figures, it is shown exaggeratedly thick for better understanding.
Die Figuren 1 und 2 illustrieren jeweils in Schnittdarstellungen die Herstellung einer bevorzugten Ausführung der erfindungsgemäßen Packung in Form einer Schlauchbeutelpackung vor Ausbildung des Verpackungsmaterialschlauches. Eine Verpackungsmaterialbahn 1, die einseitig mit einer im Profil angebrachten Siegelungsschicht und mit zwei in Bahnlängserstreckung, d.h. in den Figuren 1 und 2 senkrecht zur Zeichnungsebene verlaufende, als Sollbruchstellen für die herzustellende Packung dienende Schwächungslinien versehen ist, wird in der Verpackungsmaschine von der Rolle abgezogenen und es werden an ihr dann kontinuierlich zwei Falten 2 und 3 ausgebildet, wobei jeweils die beiden Flanken jeder Falte 2, 3 über die ganze Faltenbreite durch Versiegelung der an diesen Stellen vorhandenen Profil-Siegelschichten miteinander verbunden werden. Dabei werden die Falten 2, 3 so angebracht, daß die beiden erwähnten (in Fig. 1 senkrecht zur Zeichnungsebene verlaufenden) Schwächungslinien 4 jeweils an der inneren Faltenflanke zu liegen kommen (siehe Fig. 1). Die Falten 2, 3 werden dann auf die Ebene der Verpackungsmaterialbahn 1 umgelegt, derart, daß die Falten-Flanken, welche die Schwächungslinien 4 enthalten, nicht an der Packungsoberfläche anliegen (siehe Fig. 2).Figures 1 and 2 each illustrate in sectional views the manufacture of a preferred embodiment of the package according to the invention in the form of a tubular bag package before the packaging material tube is formed. A packaging material web 1, which is provided on one side with a sealing layer attached in the profile and with two lines of weakness which run in the longitudinal direction of the web, that is to say in FIGS. 1 and 2 perpendicular to the plane of the drawing, and serve as predetermined breaking points for the pack to be produced, is pulled off the roll in the packaging machine and two folds 2 and 3 are then continuously formed on it, the two flanks of each fold 2, 3 being connected to one another over the entire width of the fold by sealing the profile sealing layers present at these points. The folds 2, 3 are attached in such a way that the two mentioned weakening lines 4 (running perpendicular to the plane of the drawing in FIG. 1) come to rest on the inner flank flank (see FIG. 1). The folds 2, 3 are then folded over onto the level of the packaging material web 1 in such a way that the fold sides which contain the weakening lines 4 do not lie against the surface of the packaging (see FIG. 2).
Die so mit den beiden Falten 2, 3 versehene in ihrer Längsrichtung (d.h. in Fig. 2 senkrecht zur Zeichnungsebene) bewegte Verpackungsmaterialbahn 1 wird nun in üblicher Weise zur Bildung eines Verpackungsmaterialschlauches um die nacheinander zugeführten Verpackungsgutstük¬ke, z.B. Schokoladetafeln 5, in Richtung der Pfeile 6 um die Verpackungsgutstücke umgeschlagen, wonach man die Randbereiche der Verpackungsmaterialbahn an der Unterseite 7 der Schokoladetafeln 5 zur Bildung einer Längssiegelungsnaht miteinander verbindet und die durch diese Längssiegelungsnaht gebildete Finne dann auf die Schlauchoberfläche umlegt. Der die Schokoladetafeln 5 umschließende Verpackungsmaterialschlauch wird nun je weils zwischen zwei aufeinander folgenden Schokoladetafeln mit zwei parallel zueinander verlaufenden Quersiegelungsnähten versehen und durch Trennschnitte zwischen diesen beiden Quersiegelungsnähten in Einzelpackungen unterteilt.The packaging material web 1 thus provided with the two folds 2, 3 in its longitudinal direction (ie, perpendicular to the plane of the drawing in FIG. 2) is now moved in the usual way to form a packaging material tube around the successively supplied packaging items, for example chocolate bars 5, in the direction of Arrows 6 are turned around the packaged goods, after which the edge regions of the packaging material web on the underside 7 of the chocolate bars 5 are connected to form a longitudinal sealing seam and the fin formed by this longitudinal sealing seam is then folded over onto the tube surface. The packaging material tube enclosing the chocolate bars 5 is now each Weil between two consecutive chocolate bars with two parallel sealing seams running parallel to each other and divided into individual packs by separating cuts between these two transverse sealing seams.
Die so hergestellte Schlauchbeutelpackung wird in Fig. 3 in etwas vergrößertem Maßstab in einer perspektivischen Teildarstellung gezeigt. In Fig. 3 erkennt man die auf die Packungsoberfläche umgelegten Längssiegelungsnaht 8 und die durch eine Quersiegelungsnaht 9 erzeugte Flosse 10. Zwischen dem freien Rand 11 dieser Flosse 10 und dem streifenförmigen Siegelungsbereich 12 der Quersiegelungsnaht 9 befindet sich ein streifenförmiger Bereich 13 einer Breite von etwa 3 bis 8 mm, in welchem der Verpakkungsmaterialschlauch nur zusammengedrückt ist. Aus Fig. 3 erkennt man ferner die beiden auf die Packungsoberfläche umgelegten Falten 2, 3, deren äußeren Faltenränder jeweils mit den beiden Seitenrändern 14, 15 der Packung abschließen. Die beiden Schwächungslinien 4 und der zwisehen den Enden 16 dieser Schwächungslinien liegende freie Rand 17 der in Fig. 4 oben liegende Verpackungsmateriallage der Flosse 10 begrenzen so an drei Seiten einen Aufreißbereich 18 der Packungshülle.The tubular bag package thus produced is shown in a somewhat enlarged scale in a partial perspective view in FIG. 3. 3 shows the longitudinal sealing seam 8 folded over on the packaging surface and the fin 10 produced by a transverse sealing seam 9. Between the free edge 11 of this fin 10 and the strip-shaped sealing region 12 of the transverse sealing seam 9 there is a strip-shaped region 13 with a width of approximately 3 up to 8 mm, in which the packaging material hose is only compressed. From Fig. 3 can also be seen the two folds 2, 3 folded over on the pack surface, the outer fold edges of which each end with the two side edges 14, 15 of the pack. The two weakening lines 4 and the free edge 17 between the ends 16 of these weakening lines of the packaging material layer of the fin 10 lying at the top in FIG. 4 thus delimit a tear-open area 18 of the packaging envelope on three sides.
Zum Öffnen der Packung werden mit der einen Hand die in Fig. 3 unten liegende Verpackungsmaterialläge der Flosse 10 bei 19 festgehalten und die den Aufreißbereich 18 enthaltende, obere Verpackungsmateriallage an ihrem freien Rand 17 mit der anderen Hand angefaßt und in Richtung des Pfeiles 20 gezogen. Dabei werden an den beiden Falten 2, 3 bei gleichzeitigem Einreißen des Verpackungsmaterials an den Schwächungslinien 4 die Ränder des Aufreißbereiches 18 von den übrigen Teilen der Fal ten 2, 3 unter Auftrennung der diese Falten fixierenden Versiegelung abgeschält.To open the package, the packaging material layer of the fin 10 at the bottom in FIG. 3 is held at 19 with one hand and the upper packaging material layer containing the tear-open area 18 is gripped at its free edge 17 with the other hand and pulled in the direction of arrow 20. The edges of the tear area 18 of the other parts of the case are on the two folds 2, 3 with simultaneous tearing of the packaging material on the weakening lines 4 ten 2, 3 peeled off with the seal fixing these folds.
Fig. 4 zeigt die Packung in einer analogen Darstellung wie in Fig. 3; nun aber in halb geöffnetem Zustand. Man erkennt den abgezogenen Teil des Aufreißbereiches 18 und die abgeschälten streifenförmigen Bereiche 21 der zur Fixierung der Falten 2, 3 dienenden Versiegelungen.Fig. 4 shows the pack in an analog representation as in Fig. 3; but now in a half-open condition. One can see the peeled-off part of the tear-open area 18 and the peeled strip-shaped areas 21 of the seals serving to fix the folds 2, 3.
Bei der vorstehend beschriebenen Packung wird beispielsweise ein dreischichtig aufgebautes Verpackungsmaterial verwendet - welches von der Packungsaußenseite ausgehend aus einer 0,012 bis 0,015 mm starken Folie aus biaxial gerecktem Polypropylen (OPP), einer an der Außenseite mit einem dekorativen Aufdruck versehenen 0,008 bis 0,009 mm starken Aluminiumfolie, einem Papier einer Grammatur von 40 bis 50 g/m2 und einer vorzugsweise im Profil angebrachten Kaltkleberbeschichtung auf Latexbasis (z.B. ca. 3 g/m2 Feststoff) besteht. Die Schwächungslinien bestehen dabei jeweils aus mehreren im Schwächungslinienverlauf nacheinander angeordneten und voneinander getrennten linienförmigen Durchstanzungen. Diese linienförmigen Durchstanzungen können bei der Herstellung der Verpackungsmaterialbahn aber auch mit Hilfe einer geeigneten Vorrichtung an der Verpackungsmaschine unmittelbar vor Ausbildung der Falten 2, 3 in der Verpackungsmaterialbahn angebracht werden.In the case of the pack described above, for example, a three-layer packaging material is used - which, starting from the outside of the pack, consists of a 0.012 to 0.015 mm thick film made of biaxially stretched polypropylene (OPP), a 0.008 to 0.009 mm thick aluminum film provided on the outside with a decorative imprint, a paper with a grammage of 40 to 50 g / m 2 and a latex-based cold adhesive coating preferably applied in the profile (for example approx. 3 g / m 2 solid). The weakening lines each consist of a plurality of line-shaped punchings arranged one after the other in the course of the weakening line and separated from one another. However, these line-shaped punchings can also be applied to the packaging machine immediately before the folds 2, 3 are formed in the packaging material web with the aid of a suitable device when producing the packaging material web.
Anhand der Figuren 5 bis 8 sei nachstehend eine weitere vorteilhafte Ausführung der erfindungsgemäßen Packung beschrieben.A further advantageous embodiment of the pack according to the invention is described below with reference to FIGS. 5 to 8.
Zur Herstellung der Packung in Form einer Schlauchbeutelpackung wird zunächst, analog wie anhand der Figuren 1 und 2 beschrieben, in der Verpackungsmaschine eine Verpackungsmaterialbahn 22, die einseitig mit einer im Profil angebrachten Siegelungsschicht versehen ist, die nun aber im Gegensatz zu der Packungsvariante gemäß den Figuren 1 bis 4 keine Schwächungsl inien aufweist, von der Rolle abgezogen und in ihr, analog wie anhand der Figuren 1 und 2 beschrieben, kontinuierlich zwei Falten 23 und 24 gebildet (siehe Fig. 5). Anschließend werden an den Faltenkanten jeweils ein in Faltenlängserstrekkung d.h. in Fig. 5 senkrecht zur Zeichnungsebene verlaufender streifenförmiger Bereich 25 der Falte 23 bzw. 24, der in Fig. 5 durch strichlierte Linien dargestellt ist, kontinuierlich abgeschnitten, so daß das restliche Material der Falten Dopplungsbereiche 23' und 24' des Verpackungsmaterials bildet. Diese Dopplungsbereiche 23' und 24' werden dann, wie in Fig. 6 dargestellt, auf die Ebene der Verpackungsmaterialbahn 1 umgelegt.To produce the pack in the form of a tubular bag pack, first of all, analogously to the figures 1 and 2, in the packaging machine a packaging material web 22 which is provided on one side with a sealing layer applied in the profile, but which in contrast to the packaging variant according to FIGS. 1 to 4 now has no lines of weakness, is pulled off the roll and in it, Analogously to that described with reference to FIGS. 1 and 2, two folds 23 and 24 are continuously formed (see FIG. 5). Subsequently, a strip-shaped region 25 of the folds 23 and 24, which in FIG. 5 runs perpendicular to the plane of the drawing and is shown in FIG. 5 by dashed lines, is continuously cut off at the fold edges, so that the remaining material of the folds has doubling regions 23 'and 24' of the packaging material forms. These doubling regions 23 'and 24' are then folded over, as shown in FIG. 6, to the level of the packaging material web 1.
Die so mit Dopplungsbereichen 23' und 24' versehene Verpackungsmaterialbahn 22 wird nun, analog wie anhand von Fig. 2 beschrieben, zur Herstellung einer Schlauchbeutelpackung für Schokoladetafeln 5 verwendet.The packaging material web 22 thus provided with doubling regions 23 'and 24' is now used, analogously to that described with reference to FIG. 2, to produce a tubular bag pack for chocolate bars 5.
Fig. 7 zeigt die so hergestellte Schlauchbeutelpackung in einer perspektivischen Teildarstellung. Man erkennt die auf die Packungsoberfläche umgelegte Längssiegelungsnaht 8' und die durch eine Quersiegelungsnaht 9' erzeugte Flosse 10' . Analog wie bei der Packung gemäß Fig. 3 befindet sich zwischen dem freien Rand 11' dieser Flosse 10' und dem streifenförmigen Siegelungsbereich 12' ein streifenförmiger Bereich 13', in welchem der Verpackungsmaterialsehlauch nur zusammengedrückt ist. Aus Fig. 7 erkennt man ferner die beiden auf die Packungsoberfläche umgelegten Dopplungsbereiche 23' und 24' . Zum öffnen der Packung werden mit der einen Hand die in Fig. 7 unten liegende Verpackungsmaterial läge der Flosse 10' bei 19' festgehalten und die den Aufreißbereich 25 enthaltende, obere Verpackungsmaterial läge an ihrem freien Rand 17' mit der anderen Hand angefaßt und in Richtung des Pfeiles 20' abgezogen. Dabei werden die Siegelungsverbindungen der beiden Dopplungsbereiche 23' und 24' abgeschält. In Fig. 8 ist diese Packung in einer analogen Darstellung wie in Fig. 7; nun aber in halb geöffnetem Zustand, d.h. bei der ein Teil des Aufreißbereiches 26 bereits abgezogen ist, dargestellt.Fig. 7 shows the tubular bag package thus produced in a perspective partial view. One recognizes the longitudinal sealing seam 8 'folded over onto the packaging surface and the fin 10' produced by a transverse sealing seam 9 '. Analogously to the package according to FIG. 3, between the free edge 11 'of this fin 10' and the strip-shaped sealing region 12 'there is a strip-shaped region 13' in which the packaging material tube is only compressed. 7 also shows the two doubling regions 23 'and 24' which have been folded over onto the packaging surface. To open the package, the packaging material lying at the bottom in FIG. 7 would be held by the fin 10 'at 19' and the upper packaging material containing the tear-open area 25 would be grasped at its free edge 17 'with the other hand and in the direction deducted from the arrow 20 '. The sealing connections of the two doubling areas 23 'and 24' are peeled off. In Fig. 8 this pack is in an analog representation as in Fig. 7; but now shown in a half-open state, ie in which part of the tear-open area 26 has already been removed.
Bei dieser Packung wird z.B. ein sehr einfach aufgebautes Verpackungsmaterial eingesetzt, das - von der Pakkungsaußenseite ausgehend - aus einem dekorativen Aufdruck, einer Metallisierung, einer 0,02 bis 0,04 mm starken OPP-Folie und aus einer Kalbkleberbeschichtung auf Latexbasis (z.B. 3g/m2 Feststoff) besteht.In this pack, for example, a very simple packaging material is used, which - starting from the outside of the pack - consists of a decorative print, a metallization, a 0.02 to 0.04 mm thick OPP film and a latex-based calf adhesive coating (e.g. 3g / m 2 solid).
Gemäß weiteren Ausgestaltungen der Erfindung können die auf die Packungsoberfläche umgelegten Dopplungsbereiche 23', 24' mit der Packungsoberfläche durch Verklebung oder Verschweißung verbunden sein.According to further refinements of the invention, the doubling regions 23 ', 24' which are folded over onto the packing surface can be connected to the packing surface by gluing or welding.
Im ersten Fall wird z.B. vor dem Umlegen der Dopplungsbereiche 23', 24' auf die Verpackungsmaterialbahn 22 auf diese an den vorgesehenen Verklebestellen 27 (siehe Fig. 5) über punktförmige Bereiche Heißkleber (Hotmelt) aufgebracht, wonach die Dopplungsbereiche umgelegt und an die Verpackungsmaterialbahn 22 kurz angepreßt werden, wodurch die Verklebung vollzogen ist.In the first case e.g. Before the doubling areas 23 ', 24' are folded onto the packaging material web 22, hot glue (hotmelt) is applied to them at the intended bonding points 27 (see FIG. 5), after which the doubling areas are folded over and pressed briefly onto the packaging material web 22, whereby the bonding is complete.
Im zweiten Fall werden bereits bei der Verpackungsmaterialherstellung an der Außenseite des Verpackungsmate rials an den Stellen 27 und 28 jeweils streifenförmige Beschichtungen aus einem Heißsiegellack z.B. einem auf Basis von PVC/PVAc Mischpolymerisat (Auftragsstärke 1 bis 3g/m2) aufgebracht. In der Verpackungsmaschine werden dann nach dem Umlegen der Dopplungsbereiche 23', 24' diese durch Heißsiegelung mit der Verpackungsmaterialbahn 22 verbunden.In the second case, the packaging material is already on the outside of the packaging material rials at points 27 and 28 each applied strip-shaped coatings from a heat-sealing lacquer, for example one based on PVC / PVAc copolymer (application thickness 1 to 3 g / m 2 ). In the packaging machine, after the doubling areas 23 ', 24' have been folded over, they are connected to the packaging material web 22 by heat sealing.
