Abstract

At a point (2) where the packaging material is doubled and forms the tubular package flaps where there is one of the two transverse sealing seams, a tubular package has a tab to aid in opening this transverse sealing seam. This tab may be formed by the end (7) of a fold (6) in the package material projecting from the package casing surface, the edge of a layer of the package material in the doubled region itself or an adhesive label (15) secured to this layer, whereby this doubled region (2) in the transverse sealing seam is advantageously wrapped with the label (15) over the end (18) of the package and the label (15) is secured to a region of the outer casing lying outside the doubled region (2) by a releasable adhesive or other seal within the area where it projects beyond the free edge of the doubled region (2) of the transverse sealing seam.

Description

Technisches GebietTechnical field

Die Erfindung betrifft eine Packung mit einer aus einer ein- oder mehrschichtigen Verpackungsfolie bestehenden Hülle, die zwei im wesentlichen senkrecht zueinander verlaufende streifenförmige Dopplungsbereiche aufweist, in welchen jeweils zwei streifenförmige Randzonen der Verpackungsfolie an den normalerweise dem Verpackungsgut zugewandten Oberflächen durch eine lösbare Siegelung, insbesondere durch eine Kaltsiegelung, miteinander verbunden sind und daher von der Packungs-Hülle flossenartig ausgehen, und einer der Dopplungsbereiche an seinem Ende den zweiten Dopplungsbereich kreuzt, wobei für das Öffnen der Packung die Siegelverbindung zumindest eines der Dopplungsbereiche aufgetrennt wird. Die erfindungsgemäßen Packungen sollen dabei vorzugsweise, jedoch nicht ausschließlich als Schlauchbeutelpackungen oder Beutelpackungen z. B. für Dauerbackwaren eingesetzt werden.The invention relates to a package with a casing consisting of a single-layer or multilayer packaging film, which has two essentially perpendicular strip-shaped doubling areas, in each of which two strip-shaped edge zones of the packaging film on the surfaces normally facing the packaging material by a releasable seal, in particular by a cold seal, which are connected to one another and therefore emanate from the packing envelope in a fin-like manner, and one of the doubling areas at its end crosses the second doubling area, the seal connection at least one of the doubling areas being separated for opening the pack. The packs according to the invention are preferably, but not exclusively, as tubular bag packs or bag packs, e.g. B. used for baked goods.

Stand der TechnikState of the art

Eine Schlauchbeutelpackung dieser Art, die insbesondere zum Verpacken von Schokoladetafein dient, ist aus der DE-A 24 58 462 bekannt. Der aufzutrennende Dopplungsbereich ist hier die Längssiegelungsnaht, welche insbesondere an einer Teilungskerbe der Schokoladetafel an der dieser Kerbe abgewandten Rückseite der Packungs-Hülle liegt. 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.A tubular bag pack of this type, which is used in particular for packaging chocolate tafa, is known from DE-A 24 58 462. The doubling area to be separated here is the longitudinal sealing seam, which lies in particular on a division 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 edges of the packaging material which are connected to one another 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 open up an opening in the package envelope.

Die in der genannten DE-A beschriebene Packung wurde in den letzten Jahren in großem Umfang als Schokoladepackung benutzt.The package described in said DE-A has been used extensively as a chocolate package in recent years.

Sie ist aber nur dort einsetzbar, wo das Packungsgut für das Öffnen der Packung abgeknickt werden kann, und hat sich nur für kleine Packungen bewährt, deren Inhalt, wenn auch nicht vollständig unmittelbar nach dem Öffnen der Packung, so doch in relativ kurzer Zeit verbraucht zu werden pflegt. Für größere Packungen, insbesondere solche, wo das geschilderte Abknicken der Packung nicht möglich ist, also z.B. für Packungsgüter, die innerhalb der Packungs-Hülle noch in einem sogenannten Tray aufgenommen sind, oder wo das Packungsgut durch den Abknickvorgang zerstört oder unansehnlich würde, ist der Einsatz des in der DE-A 24 58 462 beschriebenen Packungssystems nicht möglich bzw. nicht anzuraten.However, it can only be used where the packaged goods can be kinked to open the pack, and has only proven itself for small packs, the contents of which, if not completely immediately after opening the pack, are used up in a relatively short time are maintained. For larger packs, especially those where the described kinking of the pack is not possible, e.g. For packaged goods which are still contained in a so-called tray within the pack envelope, or where the packaged goods would be destroyed or unsightly by the kinking process, the use of the pack system described in DE-A 24 58 462 is not possible or not advisable.

Beschreibung der Zeichnungen und einige Wege zur Ausführung der ErfindungDescription of the drawings and some ways of carrying out the invention

Die Erfindung wird nachstehend anhand der Figuren, die bevorzugte Auführungsbeispiele der erfindungsgemäßen Packung illustrieren, eingehend erläutert.The invention is explained in detail below with reference to the figures, which illustrate preferred exemplary embodiments of the pack according to the invention.

Fig. 1 zeigt eine perspektivische Teildarstellung und Fig. 2 eine Schnittdarstellung gemäß den Linien II-II in Fig. 1 einer Schlauchbeutelpackung, wie sie z.B. für Dauerbackwaren benutzt werden kann. Dabei ist, wie auch in den übrigen Figuren, zur Verbesserung der Deutlichkeit der Darstellung, das Verpackungsmaterial übertrieben dick dargestellt. Die Packung weist - wie bei Schlauchbeutelpackungen üblich - eine Finne 1 (siehe Fig. 2) und an den beiden Enden jeweils eine quer zur Finne 1 verlaufende Flosse 2 auf. Die Finne 1 bzw. die Flosse 2 bilden dabei im allgemeinen senkrecht zueinander verlaufende Verpackungsfolien-Dopplungsbereiche, in welchen jeweils zwei streifenförmige Randzonen der Verpackungsfolie an den normalerweise dem Verpakkungsgut 3 (siehe Fig. 2) zugewandten Oberflächenbereich durch eine Kaltsiegelung miteinander verbunden sind. Der die Finne 1 bildende Dopplungsbereich kreuzt dabei an seinem Ende 4 den die Flosse 2 bildenden Dopplungsbereich. Wie aus den Figuren 1 und 2 ersichtlich, ist die Finne 1 auf die Hüllenoberfläche 5 (Fig. 2) umgelegt.Fig. 1 shows a partial perspective view and Fig. 2 is a sectional view according to lines II-II in Fig. 1 of a tubular bag package, such as can be used for example for baked goods. Here, as in the other figures, to improve the clarity of the representation, the packaging material is exaggerated. The pack has - as is usual with tubular bag packs - a fin 1 (see FIG. 2) and a fin 2 running at both ends at right angles to the fin 1. The fin 1 or the fin 2 in this case form, in general, mutually perpendicular packaging film doubling areas, in each of which two strip-shaped edge zones of the packaging film form on the surface area normally facing the packaged goods 3 (see FIG. 2) a cold seal are connected. The doubling area forming the fin 1 crosses at its end 4 the doubling area forming the fin 2. As can be seen from FIGS. 1 and 2, the fin 1 is folded over onto the casing surface 5 (FIG. 2).

Die anhand der Figuren 1 und 2 beschriebene Variante der erfindungsgemäßen Packung weist nun in der Verpackungsfolie eine von der Hüllenoberfläche 5 ausgehende Falte 6 auf, die - in etwa symmetrisch zur Finne 1 verlaufend - an der der Finne 1 entgegengesetzten Seite der Packungs-Hülle angeordnet ist und die mit ihrem Ende 7 die Flosse 2 kreuzt und dort dem Ende 4 der Finne 1 gegenüberliegt. Dabei sind die Finne 1 und die Falte 6 in einander entgegengesetzten Richtungen auf die betreffenden Oberflächen der Flosse 2 umgeschlagen, so daß die Finne 1 und die Falte 6 im Bereich der Flosse 2 nicht übereinander liegen.The variant of the package according to the invention described with reference to FIGS. 1 and 2 now has a fold 6 in the packaging film which extends from the envelope surface 5 and which - running approximately symmetrically to the fin 1 - is arranged on the side of the package envelope opposite the fin 1 and which crosses the fin 2 with its end 7 and lies opposite the end 4 of the fin 1 there. The fin 1 and the fold 6 are turned over in opposite directions on the surfaces of the fin 2 in question, so that the fin 1 and the fold 6 do not lie one above the other in the region of the fin 2.

Bei der Herstellung der vorstehend beschriebenen Packung wird beispielsweise eine dreischichtige Verpackungsfolie verwendet, welche - von der Packungsaußenseite ausgehend - in nachstehender Reihenfolge aus einer OPP-Folie einer Dicke von 12 - 20 »m, einer 7 - 9 »m starken Aluminiumfolie und einem gebleichten Kraftpapier einer Grammatur von 40 - 60 g/m² besteht. Die freie Papierseite ist mit einer im Profil aufgebrachten Kaltkleberbeschichtung als Siegelmediumschicht auf Latexbasis (3 - 7 g/m² Feststoff) beschichtet. Die Gesamtstärke dieses Verbundmaterials beträgt 70 - 100 »m, je nach Wahl der Verbundpartner. Die als Endlosbahn vorliegende Verpackungsfolie wird in der Verpackungsmaschine von der Rolle abgezogen und zur kontinuierlichen Bildung der Falte 6 werden die beiden den Dopplungsbereich der Falte 6 bildenden Verpackungsmaterialzonen über die ganze oder einen Teil der Faltenbreite durch Versiegelung von an diesen Stellen vorhandenen Profil-Siegelschichten miteinander verbunden, wonach die Falte 6 auf die Oberfläche der Verpackungsfolienbahn umgelegt wird.In the production of the package described above, for example, a three-layer packaging film is used, which - starting from the outside of the package - in the following order from an OPP film with a thickness of 12-20 »m, a 7-9» m thick aluminum film and a bleached kraft paper a grammage of 40 - 60 g / m². The free paper side is coated with a cold adhesive coating applied in the profile as a sealing medium layer based on latex (3 - 7 g / m² solid). The total thickness of this composite material is 70 - 100 »m, depending on the choice of the composite partner. The packaging film, which is in the form of an endless web, is pulled off the roll in the packaging machine and for the continuous formation of the fold 6 the two packaging material zones forming the doubling region of the fold 6 are connected to one another over the whole or part of the fold width by sealing profile sealing layers present at these points , after which the fold 6 is folded over the surface of the packaging film web.

Die so in Bahnenlängsrichtung mit der Falte 6 versehene Verpackungsmaterialbahn 1 wird nun in üblicher Weise um die nacheinander zugeführten Verpackungsguteinheiten - z.B. in Trays aufgenommene Dauerbackwaren wie Kekse oder Waffeln - kontinuierlich umgeschlagen und durch miteinander Verbinden der seitlichen Randzonen der Verpackungsfolienbahn mittels einer Längssiegelnaht die Finne 1 ausgebildet, die danach auf die Oberfläche des so gebildeten Verpackungsfolienschlauches umgeschlagen wird. Dieser Verpackungsfolienschlauch wird dann jeweils zwischen zwei aufeinanderfolgenden Verpackungsguteinheiten in Richtung der Pfeile 8 zur Bildung von einander gegenüberliegenden Zwickeln eingefaltet,mit zwei parallel zueinander verlaufenden Quersiegelnähten abgequetscht und durch Trennschnitte zwischen den beiden Quersiegelnähten in Einzelschlauchpackungen unterteilt. Dabei bilden die durch die Quersiegelnähte miteinander verbundenen Randbereiche des Verpackungsmaterials die Flossen 2 mit den durch die Zwickelbildung entstehenden Verdopplungszonen 9. Die Ränder der Quersiegelnaht sind durch die Linien 10 angedeutet sind.The packaging material web 1 thus provided with the fold 6 in the longitudinal direction of the web is now in the usual way around the successively supplied packaging material units - e.g. Permanent baked goods such as biscuits or waffles taken up in trays - continuously turned over and, by connecting the lateral edge zones of the packaging film web to one another by means of a longitudinal sealing seam, the fin 1 is formed, which is then turned over onto the surface of the packaging film tube formed in this way. This packaging film tube is then folded in each case between two successive packaged goods units in the direction of arrows 8 to form opposing gussets, squeezed off with two transverse sealing seams running parallel to one another and divided into individual tube packages by separating cuts between the two transverse sealing seams. The edge regions of the packaging material which are connected to one another by the transverse sealing seams form the fins 2 with the doubling zones 9 resulting from the gusset formation. The edges of the transverse sealing seam are indicated by the lines 10.

Fig. 3 zeigt die Packung in einer Darstellung nacn Art von Fig. 1, nun aber während des Öffnungsvorganges. Zum Öffnen der Packung werden zunächst die Enden 4 und 7 der Finne 1 bzw. der Falte 6 mit beiden Händen angefaßt und dabei in Richtung der Pfeile 11 bzw. 12 (siehe Fig. 1) aufgebogen und anschließend, wie in Fig. 3 illustriert, in Richtung der Pfeile 13 bzw. 14 auseinandergezogen. Dabei wird die (Quer-)Siegelungsnaht der Flosse 2 von der Flossenmitte ausgehend über einen Teil ihrer Länge, bei Bedarf aber auch vollständig aufgeschält. Durch die so entstandene Öffnung kann dann Verpackungsgut entnommen werden. Danach besteht die Möglichkeit, die beim Öffnen der Packung in der Flosse 2 voneinander getrennten Verpackungsfolienränder durch einfaches Zusammendrücken wieder miteinander zu verkleben und die Packung so wieder behelfsmäßig zu verschließen.Fig. 3 shows the pack in a representation of the type of Fig. 1, but now during the opening process. To open the pack, first grasp the ends 4 and 7 of the fin 1 or the fold 6 with both hands and bend them in the direction of the arrows 11 and 12 (see FIG. 1) and then, as illustrated in FIG. 3, pulled apart in the direction of arrows 13 and 14 respectively. The (transverse) sealing seam of fin 2 is peeled over part of its length from the center of the fin, but is also completely peeled off if necessary. Packaging material can then be removed through the opening thus created. Thereafter, it is possible to glue the packaging film edges separated from one another when the package is opened in the fin 2 by simply pressing them together, and thus to temporarily seal the package again.

Bei einer Variante der erfindungsgemäßen Packung besteht die Packungshülle zur Hälfte aus einem durchsichtigen Material.In a variant of the package according to the invention, half of the package cover consists of a transparent material.

Für die Herstellung dieser Packung geht man von zwei unterschiedlichen Verpackungsfolienbahnen aus, die an ihren Innenseiten im Profil aufgebrachte Kaltkleberbeschichtungen aufweisen, und von denen eine aus einem durchsichtigen Material besteht. Die beiden Verpackungsfolienbahnen werden nun aneinanderliegend kontinuierlich der Verpackungsmaschine zugeführt und an einem Rand über einem streifenförmigen Randbereich durch Herstellung einer Längssiegelnaht miteinander verbunden. Danach werden - ebenfalls kontinuierlich - beide Verpackungsfolienbahnen hart am Rand der Längssiegelungsnaht aufgefaltet, derart daß sie dann mit ihren Innenseiten nach unten zu liegen kommen und gemeinsam eine kombinierte Verpackungsfolienbahn bilden, welche nun an einer Oberfläche anstelle der Falte 6 gemäß Fig. 1 eine Längssiegelnaht aufweist. Aus dieser kombinierten Verpackungsfolienbahn wird dann wie üblich eine Schlauchbeutelpackung hergestellt, welche nun aber zwei finnenartige Längssiegelnähte aufweist, die am Dopplungsbereich 2 (siehe Fig. 1) einander gegenüberliegen und ähnlich wie die Falte 6 und die Finne 1 gemäß Fig. 3 an ihren Enden angefaßt zum Öffnen der Packung dienen.Two different packaging film webs are used for the production of this pack, which have cold-adhesive coatings applied to the inside of their profile, and one of which consists of a transparent material. The two packaging film webs are now continuously fed to the packaging machine lying against one another and are connected to one another at an edge over a strip-shaped edge region by producing a longitudinal sealing seam. Then - also continuously - both packaging film webs are unfolded hard at the edge of the longitudinal sealing seam, so that they then come to rest with their inner sides down and together form a combined packaging film web which now has a longitudinal sealing seam on one surface instead of the fold 6 according to FIG. 1 . From this combined packaging film web a tubular bag pack is then produced as usual, but which now has two fin-like longitudinal sealing seams, which are opposite one another at the doubling area 2 (see FIG. 1) and, similar to the fold 6 and the fin 1 according to FIG. 3, are handled at their ends serve to open the package.

Als Material für die undurchsichtige Verpackungsfolienbahn dient dabei z.B. dieselbe dreilagige Verpackungsfolie, wie sie z.B. auch bei der Packung gemäß den Fig. 1 bis 3 verwendet wurde. Als durchsichtiges Verpackungsmaterial kommen Verpackungsfolien zum Einsatz, die z.B. aus einer 50 »m starken OPP-Monofolie bestehen können oder auch aus Verbundfolien bestehend z.B. - jeweils von außen nach innen - aus 12 »m PET und 60 »m PE oder 20 »m PA und 40 »m PE, wobei die PE-Schicht durch Schmelzextrusion oder durch Folienkaschierung hergestellt ist.The material for the opaque packaging film web is e.g. the same three-layer packaging film as e.g. was also used in the pack according to FIGS. 1 to 3. Packaging films are used as transparent packaging material, e.g. can consist of a 50 »m thick OPP monofilm or also consist of composite foils e.g. - in each case from the outside to the inside - from 12 »m PET and 60» m PE or 20 »m PA and 40» m PE, the PE layer being produced by melt extrusion or by film lamination.

Eine andere Variante der erfindungsgemäßen Packung sei nun anhand der Figuren 4 bis 6 beschrieben. Fig. 4 zeigt dabei in einer perspektivischen Teildarstellung eine Schlauchbeutelpackung vor dem endgültigen Verschließen, die, ähnlich wie die Packung gemäß Fig. 1, und wie bei Schlauchbeutelpackungen üblich, eine Packungs-Hülle mit einer durch eine Längssiegelnaht erzeugten Finne 1 und zwei durch die Herstellung von Quersiegelnähten am Verpackungsfolienschlauch und die Unterteilung in Einzelpackungen erzeugte Flossen 2 aufweist. Anders als bei der Variante gemäß Fig. 1 ist hier aber keine Falte 6 vorgesehen, deren Ende 7 eine der beiden Handhaben zum Öffnen der Packung bildet, sondern es wird z.B. an der dem Ende 4 der Finne 1 gegenüberliegenden Oberflächenseite und diesem Ende 4 der Finne 1 gegenüberliegend eine Klebeetikett 15 als Handhabe im Bereich 16 aufgeklebt. Dieses Klebeetikett besteht z.B. aus einem einseitig mit einer Selbstkleberbeschichtung versehenen flächigen Material, z.B.aus mit PE beschichtetem Papier oder einer Kunststofffolie mit einer der Dicke des Hüllenmaterial annähernd entsprechenden Gesamtstärke von z.B. 70 - 100 »m wie bei dem anhand der Figuren 1 bis 3 beschriebenen Beispiel. In einem Randbereich 17 des Klebeetiketts 15 ist die Kleberbeschichtung durch eine Lackschicht abgedeckt.Another variant of the pack according to the invention is now based on of Figures 4 to 6 described. Fig. 4 shows a perspective partial view of a tubular bag pack before final closure, which, similar to the pack according to Fig. 1, and as is customary with tubular bag packs, a packing envelope with a fin 1 produced by a longitudinal seal seam and two by manufacture of fins 2 produced by transverse sealing seams on the packaging film tube and the subdivision into individual packs. In contrast to the variant according to FIG. 1, however, there is no fold 6 here, the end 7 of which forms one of the two handles for opening the pack, but it is, for example, on the surface side opposite the end 4 of the fin 1 and this end 4 of the fin 1, an adhesive label 15 is glued on opposite side as a handle in area 16. This adhesive label consists, for example, of a flat material provided on one side with a self-adhesive coating, for example made of paper coated with PE or a plastic film with a total thickness of approximately 70-100 »m approximately corresponding to the thickness of the sleeve material, as in the example described with reference to FIGS. 1 to 3. In an edge region 17 of the adhesive label 15, the adhesive coating is covered by a layer of lacquer.

Zum Fertigverschließen der Packung wird die Flosse 2 mit dem angebrachten Klebeetikett 15 in Richtung des Pfeiles 18, d.h. auf die Finne 1 hin auf das Packungsende 19 umgeschlagen, wonach es Klebeetiketts 15 mit jener Packungs-Oberflächenseite 21 (siehe Fig. 5) verbunden wird, längs welcher sich die Finne 1 erstreckt.To finish sealing the package, the fin 2 is attached with the attached adhesive label 15 in the direction of arrow 18, i.e. turned over to the fin 1 towards the end of the pack 19, after which adhesive labels 15 are connected to that side of the pack surface 21 (see FIG. 5) along which the fin 1 extends.

Zum Öffnen der Packung wird das Klebeetikett 15 an dem laschenartig leicht abstehenden Randbereich 17 angefaßt, in Richtung des Pfeiles 22 nach oben gezogen, wobei das Klebeetikett 15 von der Packungsoberflächenseite 21 abgeschält und die Flosse 2 wieder aufgerichtet wird, so daß sich etwa eine Konfiguration wie in Fig. 4 gezeigt ergibt. Das Ende 4 der Finne 1 wird nun in Richtung des Pfeiles 23 (Fig. 4) aufgebogen. Dieses aufgebogene Finnen-Ende 4 wird nun mit der einen Hand und der Randbereich 17 des Klebeetiketts mit der anderen Hand angefaßt und beide in Richtung der Pfeile 24, 25 (siehe Fig. 6) auseinandergezogen.To open the package, the adhesive label 15 is gripped at the edge region 17, which protrudes slightly in the manner of a tab, and is pulled upwards in the direction of the arrow 22, the adhesive label 15 being peeled off the side of the package surface 21 and the fin 2 being raised again, so that a configuration such as shown in Fig. 4. The end 4 of the fin 1 is now bent in the direction of the arrow 23 (FIG. 4). This bent up Fin end 4 is now gripped with one hand and the edge region 17 of the adhesive label with the other hand and both are pulled apart in the direction of arrows 24, 25 (see FIG. 6).

Dabei wird die Siegelverbindung der Flosse 2 aufgeschält und die Packung so geöffnet. In Fig. 6, welche die Packung während dieses Öffnungsvorganges zeigt, erkennt man den Bereich 26 der Siegelmediumschicht der aufgetrennten Siegelverbindung der Flosse 2.The seal connection of fin 2 is peeled off and the package is opened in this way. 6, which shows the package during this opening process, shows the region 26 of the sealing medium layer of the separated sealing connection of the fin 2.

Die vorstehend anhand der Figuren 4 bis 6 beschriebene Packung ist behelfsmäßig wiederverschließbar: man muß nur das Material der Flosse 2 wiederzusammenfalten, die Flosse 2 auf das Packungsende 19 umlegen und den Bereich 20 des Klebeetiketts 15 wieder auf der Packungs-Oberflächenseite 21 durch einfaches Andrücken befestigen.The package described above with reference to FIGS. 4 to 6 can be temporarily resealed: you only have to fold the material of the fin 2 together, fold the fin 2 onto the end of the package 19 and fasten the area 20 of the adhesive label 15 on the surface 21 of the package again by simply pressing it on .

Gemäß einer Variante der anhand Figuren 4 bis 6 beschriebenen Packung wurden an der Flosse 2 durch Aufbringen von heißem Hotmelt-Material Hotmelt-Punkte 32 (siehe Fig. 4) angebracht. Unmittelbar danach wird die Flosse 2 mit dem Klebeetikett 15 umgelegt und mit seinem Bereich 20 mit der Packungs-Oberflächenseite 21 verbunden. Nach Erstarren des Hotmelt-Materials ist eine Verklebung zwischen der Finne 2 und dem Packungsende 19 hergestellt. Zum Öffnen dieser Packung wird nur an der Randzone 17 des Klebeetiketts 15 angefaßt und nach oben gezogen. Obwohl nicht in einer besonderen Figur dargestellt, ist deutlich, daß die mit dem Packungsende 19 verklebte Verpackungsmaterial-Lage der Flosse 2 dabei zurückbleibt und dadurch die Siegelverbindung der Flosse 2 aufgetrennt wird. Bei geeigneter Dimensionierung der Hotmelt-Punktverbindung kann man erreichen, daß sie beim weiter Nachobenziehen des Klebeetiketts ebenfalls auftrennt und die Packung auf diese Weise vollständig geöffnet wird. Diese Variante hat den Vorteil, daß man für die Manipulation zum Öffnen der Packung nur eine Hand benötigt.According to a variant of the pack described with reference to FIGS. 4 to 6, hot melt points 32 (see FIG. 4) were attached to the fin 2 by applying hot hot melt material. Immediately thereafter, the fin 2 is folded over with the adhesive label 15 and its area 20 is connected to the pack surface 21. After the hot melt material has solidified, an adhesive bond is produced between the fin 2 and the end of the pack 19. To open this pack, only touch the edge zone 17 of the adhesive label 15 and pull upwards. Although not shown in a particular figure, it is clear that the packaging material layer of the fin 2 which is glued to the end of the pack 19 remains behind and the sealing connection of the fin 2 is thereby broken. With a suitable dimensioning of the hot-melt point connection, it can be achieved that it also separates when the adhesive label is pulled up further and the package is completely opened in this way. This variant has the advantage that only one hand is required for manipulation to open the package.

Anhand von Fig. 7 wird nun eine weitere Variante der erfindungsgemäßen Packung erläutert. Diese Packungsvariante ist eine Schlauchbeutelpackung, ähnlich wie in Fig. 4 dargestellt, mit dem Unterschied, daß kein Klebeetikett vorgesehen ist. Fig. 7 zeigt die Packung während des Öffnungsvorganges in einer zu Fig. 6 analogen Darstellung. Die Verpackungsmaterial-Lage 27 des Dopplungsbereichs der Flosse 2, die dem Ende 4 der Finne 1 gegenüberliegt, hat eine Siegelmediumschicht 28, welche eine Aussparung 29 aufweist, innerhalb von der die Siegelmediumschicht 28 vom Verpackungsmaterialrand 30 einen größeren Abstand aufweist. Bei geschlossener Packung klaffen daher die beiden Verpackungsmaterial- Lagen der Flosse 2 an der Stelle der Aussparung 29 etwas auseinander, so daß man die Verpackungsmaterial-Lage 27 hier problemlos anfassen kann. Die Packung wird durch Ziehen an der Verpackungsmaterial-Lage 27 bzw. an dem Ende 4 der Flosse 1 im Sinne der Pfeile 24 und 31 unter Auftrennung der Siegelverbindung der Flosse 2 geöffnet.Another variant of the pack according to the invention will now be explained with reference to FIG. 7. This pack variant is a tubular bag pack, similar to that shown in FIG. 4, with the difference that no adhesive label is provided. FIG. 7 shows the pack during the opening process in a representation analogous to FIG. 6. The packaging material layer 27 of the doubling area of the fin 2, which lies opposite the end 4 of the fin 1, has a sealing medium layer 28, which has a recess 29 within which the sealing medium layer 28 is at a greater distance from the packaging material edge 30. When the package is closed, the two packaging material layers of the fin 2 gap slightly at the location of the recess 29, so that the packaging material layer 27 can be handled here without any problems. The package is opened by pulling on the packaging material layer 27 or at the end 4 of the fin 1 in the direction of the arrows 24 and 31, with the sealing connection of the fin 2 being separated.

Gewerbliche AnwendungCommercial application

Die erfindungsgemäße Packung kann in erster Linie als Packung für Lebensmittel wie Schokoladen oder Dauerbackwaren eingesetzt werden, die gegebenenfalls gasdicht ausgeführt bzw. vorteilhaft Schlauchbeutelpackungen oder Beutelpackungen sind. Ihre gewerbliche Verwertbarkeit ist dabei jedoch nicht auf Packungen für feste Verpackungsgüter beschränkt.The pack according to the invention can primarily be used as a pack for foods such as chocolates or baked goods which are optionally gastight or which are advantageously tubular bag packs or bag packs. However, their commercial usability is not limited to packs for solid packaging goods.
