Abstract

A folding package (10) is produced from a single foil web (12) which is folded around an article to be packed and then sealed in such a way that the article is hermetically sealed by it on all sides. Here, the closure is made by adhesively securing the opposite edge regions of the foil web which border the inner region thereof. According to the invention, two opposite edge regions (26, 28) have at least one area (50, 60, 72, 74) which does not adhere permanently, whereby these areas overlap (29) in when the foil is folded to form a package (10), and one of these two edge areas (50, 72) is partially physically separated from the remaining edge region (26) along its peripheral line (54, 70, 52). The adhesive layers (40, 42) lie between these two areas (50, 60 or 72, 74) and the inner region (22, 14, 16, 18, 20) so that the inner region is laterally completely surrounded by the adhesive layers (40, 42).

Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung betrifft ein folienartiges Material für eine Faltpackung und eine dementsprechende Faltpackung, bei der das folienartige Material um ein zu verpackendes Gut so herumgefaltet und verschlossen ist, daß das Gut von ihr allseitig luftdicht umgeben ist. Das folienartige Material bzw. die Faltpackung besitzt eine einzige Folienbahn, deren gegenüberliegende Randbereiche, die den inneren Bereich der Folienbahn seitlich einrahmen, mit jeweils einer auf derselben Seite der Folienbahn vorhandenen Klebeschicht versehen sind.The invention relates to a film-like material for a Folding pack and a corresponding folding pack, in which the film-like material is folded around a product to be packaged in this way and it is closed that the good from her on all sides is airtight. The film-like material or Folding pack has a single film web, the opposite one Edge areas, which are the inner area of the film web frame laterally, with one each existing on the same side of the film web Apply adhesive layer are.

Dementsprechend hergestellte Faltpackungen dienen zum Verpacken von beispielsweise gefriergetrocknetem Kaffee, von Keksen, von sogenannten süßen Riegeln oder von sonstigen Genußmitteln, die luft- und feuchtigkeitsdicht bzw. aromadicht verpackt sein sollen.Folding packs made accordingly are used for packaging of freeze-dried coffee, for example Biscuits, from so-called sweet bars or other stimulants, the air and moisture proof or aroma proof should be packed.

STAND DER TECHNIKSTATE OF THE ART

Es ist bekannt, eine einlagige, einteilige Folienbahn um das zu verpackende Gut so zusammenzuführen, daß die Folienbahn um in Transportrichtung verlaufende Knickkanten um das Verpackungsgut herumgefaltet werden kann, wobei anschließend die freien Nahtränder durch eine Längsnaht miteinander versiegelt werden. Die Klebeschichten dieser Längsnaht sind auf derselben Seite der Folienbahn vorhanden. Die versiegelten Längsnahtbereiche bilden eine sogenannte Längsnahtflosse, die anschließend flächig auf die Außenseite der Packung umgeklappt wird, so daß sie nicht störend von der Packung wegsteht. Auch die beiden stirnseitigen Enden der Packung werden in ähnlicher Weise versiegelt, so daß anschließend das verpackte Gut allseitig von der Folienbahn luft-, feuchtigkeits- und aromadicht verschlossen ist. It is known to have a single-layer, one-piece film web around the Good to be packed so that the film web around Buckling edges in the direction of transport around the packaged goods can be folded around, after which the free seam edges sealed with a longitudinal seam will. The adhesive layers of this longitudinal seam are on the same Side of the film web available. The sealed longitudinal seam areas form a so-called longitudinal seam fin, which then folded flat onto the outside of the pack so that it does not interfere with the packaging. Also the two front ends of the pack will be similar Way sealed, so that subsequently the packaged good Air, moisture and aroma-tight on all sides of the film is closed.

Die Folienbahn selber besteht im Regelfall aus einem Verbundmaterial oder aus Aluminium.The film web itself usually consists of a composite material or made of aluminum.

Diese bekannten Faltpackungen sind technisch einwandfrei. Von Nachteil ist allerdings, daß sie sich nur schwer öffnen lassen und daß ein Öffnen ohne Zuhilfenahme eines Schneidwerkzeuges oder ohne Zerstörung des verpackten Gutes nur sehr schwer möglich ist.These known folding packs are technically flawless. From The disadvantage, however, is that they are difficult to open and that opening without the use of a cutting tool or only very much without destroying the packaged goods is difficult to do.

Aus der US-A-2,337,741 ist es bekannt, eine beispielsweise Zigarre mit einer einzigen Folienbahn luftdicht zu umhüllen. Dazu werden die gegenüberliegenden Randbereiche der Folienbahn aufeinander geklappt und durch eine gemeinsame Klebeschicht miteinander verbunden. Die Klebeschicht ist dabei auf der Außenseite des innenliegenden Randbereichs und auf der Innenseite des außenliegenden Randbereichs vorhanden. Eine Flossenausbildung der eingangs genannten Art ist dadurch nicht ausgebildet. Der freie Rand des äußeren Randbereichs weist zwei Einschnitte auf. Die zwischen diesen Einschnitten dadurch ausgebildete Lasche dient zum leichteren Aufreißen der Packung. Die Lasche kann allerdings störend vom übrigen Randbereich wegstehen.From US-A-2,337,741 it is known, for example Wrapping the cigar airtight with a single sheet of film. To do this, the opposite edge areas of the film web folded together and through a common adhesive layer connected with each other. The adhesive layer is on the outside of the inner edge area and on the Inside of the outer edge area available. A Fin training of the type mentioned is thereby not trained. The free edge of the outer edge area has two incisions. The between these cuts the flap thus formed serves for easier tearing open the pack. However, the tab can be distracting from the rest Stand out the edge area.

Letzteres trifft auch für die aus der DE-U-85 36 241 bekannte Schlauchbeutelpackung zu. Bei dieser Packung sind in ihrer Quernahtflosse zwei Einschnitte vorhanden, die durch beide miteinander durch eine Klebeschicht luftdicht verbundenen Randbereiche der Flosse hindurchgehen. Die dadurch ausgebildete Aufreiß-Lasche kann somit ebenfalls störend vom übrigen Rand wegstehen.The latter also applies to the one known from DE-U-85 36 241 Tubular bag pack too. With this pack are in their Cross seam fin two incisions present, through both connected to each other airtight by an adhesive layer Go through the edge areas of the fin. The trained thereby Tear-tab can also be distracting from the rest Edge stand out.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Der Erfindung liegt die Aufgabe zugrunde, unter Vermeidung dieser aus dem Stand der Technik bekannten Nachteile eine Faltpackung und das dazu verwendete Material anzugeben, die es erlauben, derartige Faltpackungen auf wirtschaftlich einfache Weise, auch ohne Zuhilfenahme von Schneidwerkzeugen, problemlos und auf das verpackte Gut schonende Weise zu öffnen.The invention is based, avoiding the task one of these disadvantages known from the prior art Folding pack and the material used to specify the allow such folding packs to be economically simple Way, even without the use of cutting tools, easy to open and gentle on the packaged goods.

Diese Erfindung ist für das für eine Faltpackung vorgesehene folienartige Material durch die Merkmale des Patentanspruchs 1 und für die entsprechend hergestellte Faltpackung durch die Merkmale das Patentanspruchs 3 gegeben.This invention is for that intended for a folding package film-like material by the features of the claim 1 and for the folding pack produced accordingly by Features given claim 3.

Die erfindungsgemäße Faltpackung besteht damit aus einer einzigen Folienbahn. Die gegenüberliegenden inneren Randbereiche dieser Folienbahn, die den inneren Bereich derselben seitlich einrahmen, sind mit jeweils einer Klebeschicht versehen. Der innere Bereich selber, der das zu verpackende Gut direkt umhüllt, ist nicht mit einer Klebeschicht versehen. Diese erfindungsgemäße Folienbahn zeichnet sich dadurch aus, daß die sich gegenüberliegenden beiden Randbereiche jeweils zumindest einen Teilbereich ohne Leimschicht aufweisen, wobei diese Bereiche der beiden Randbereiche im zu einer Faltpackung zusammengefalteten Zustand übereinanderliegen. Ferner ist die Folienbahn längs der Umfangslinie einer dieser beiden Randbereiche durch eine zusammenhängende Schnittlinie vom übrigen Randbereich teilweise materialmäßig getrennt, wobei im Zwischenbereich zwischen diesen beiden Teilbereichen und dem inneren Bereich die Klebeschichten vorhanden sind, so daß der innere Bereich von den Klebeschichten seitlich vollständig eingerahmt ist. Dieser eine, durch die zusammenhängende Schnittlinie vom übrigen Randbereich getrennte Teilbereich ist so orientiert, daß beim Aufreißen der Faltpackung der Zwischenbereich durch diesen einen Teilbereich aufgerissen wird. Wie beim Stand der Technik ist damit das zu verpackende Gut allseitig von einer Klebeschicht eingerahmt, so daß eine dichte Verpackung ermöglicht wird. Durch das materialmäßige Auftrennen eines der beiden übereinanderliegenden Randbereiche und das nicht miteinander verklebende Ausbilden dieser beiden Bereiche, ist es möglich, den Randbereich mit einer einseitigen Lasche auszubilden, so daß durch Ziehen an dieser Lasche die Faltpackung sich sehr leicht öffnen läßt. Dieses leichte Öffnen wird ohne materialmäßige Verteuerung erreicht. Ferner ist für die wirtschaftliche Nutzung dieser Erfindung von wesentlicher Bedeutung, daß das eigentliche Herstellen der Verpackung, nämlich das Umschlagen der Folienbahn um das zu verpackende Gut herum und das Versiegeln von Längs- und Stirnnähten ähnlich wie aus dem Stand der Technik bekannt erfolgen kann.The folding pack according to the invention thus consists of a single one Foil web. The opposite inner edge areas this film web, the inner area of the same side frame, are each provided with an adhesive layer. Of the inner area itself, which directly envelops the goods to be packaged, is not provided with an adhesive layer. This invention Film web is characterized in that the at least two opposite edge areas have a partial area without a glue layer, these areas of the two edge areas in the folded package Condition on top of each other. Furthermore, the film web along the circumference of one of these two edge areas by a coherent cutting line from the rest Border area partially separated in terms of material, with the intermediate area between these two areas and the inner one Area the adhesive layers are present, so that the Inner area of the adhesive layers laterally completely is framed. This one, through the coherent Section line separate section from the rest of the edge area is so oriented that when the folding pack is torn open the Intermediate area torn open by this one partial area becomes. As with the prior art is the goods to be packaged on all sides by one Adhesive layer framed so that a dense Packaging is made possible. Because of the material Cut one of the two Marginal areas and the non-adhesive Forming these two areas, it is possible the edge area with a one-sided tab train so that by pulling on this tab the folding pack can be opened very easily. This Easy opening is without material expensive reached. Furthermore, for the economic Use of this invention essential that the actual manufacture of the packaging, namely the wrapping of the film web around it packing good around and sealing Longitudinal and front seams similar to those from a standing position the technology can be known.

Beim Aufziehen der Packung reißt die Lasche den Zwischenbereich zwischen ihr und dem inneren Bereich auf. Dieser Zwischenbereich ist im verschlossenen Zustand der Packung mit einer Klebeschicht versehen, da das zu verpackende Gut ja allseitig verschlossen sein muß. Um dieses Aufreißen einfach zu gestalten und trotzdem eine vollständige Dichtigkeit vor dem Aufreißen in diesem Zwischenbereich zu gewährleisten, hat es sich als vorteilhaft herausgestellt, die Längsstruktur des Leimauftrags in diesem Zwischenbereich parallel zur Aufreißrichtung auszubilden.The tab breaks when the package is opened the intermediate area between it and the inner Area on. This intermediate area is closed Condition of the pack with an adhesive layer provided, since the goods to be packed are sealed on all sides have to be. To just tear this open design and still complete tightness before tearing in this intermediate area to ensure it turned out to be advantageous the longitudinal structure of the glue application in this intermediate area form parallel to the tear direction.

Weitere Einzelheiten der Erfindung sind dem nachfolgenden Ausführungsbeispiel zu entnehmen.Further details of the invention are the following embodiment refer to.

    • WEGE ZUR AUSFÜHRUNG DER ERFINDUNGWAYS OF CARRYING OUT THE INVENTION

    Eine erfindungsgemäße Faltpackung 10 besitzt eine Umhüllung, die aus einer einzigen Folienbahn 12 gebildet ist. Diese Folienbahn 12 ist in Längsrichtung L abschnittsweise und aufgeklappt in Fig. 3 dargestellt. Die zwischen der oberen Seite 14, hinteren Seite 16, unteren Seite 18 und dem unteren Bereich 20 bzw. oberen Bereich 22 der vorderen Seite auf der Packung 10 ausgebildeten Biegekanten 15, 17, 19 bzw. 21 sind in Fig. 3 gestrichelt dargestellt.A folding pack 10 according to the invention has an envelope consisting of a single film web 12 is formed. This film web 12 is in the longitudinal direction L shown in sections and opened in Fig. 3. The one between the top side 14, back side 16, lower side 18 and the lower area 20 or upper region 22 of the front side on the Pack 10 trained bending edges 15, 17, 19th and 21 are shown in dashed lines in Fig. 3.

    Auf der Faltpackung 10 ist eine sogenannte Längsnahtflosse 24 vorhanden, die durch die beiden äußeren Längsrandbereiche 26 bzw. 28 gebildet wird. Diese Längsrandbereiche 26, 28 sind im zu der Packung 10 zusammengefalteten Zustand miteinander verklebt. Längs der zwischen der Längsnahtflosse 24 und dem unteren bzw. oberen Bereich 20, 22 der Vorderseite vorhandenen Biegekante 30 ist die Längsnahtflosse 24 - in Fig. 1 nach unten - umgeklappt vorhanden. Diese Längsnahtflosse 24 reicht auch um die beiden Stirnseiten 32 der Packung 10 herum und ist dort an den jeweils dort vorhandenen Stirnnahtflossen 34 befestigt.On the folding pack 10 is a so-called Longitudinal seam fin 24 present by the two outer longitudinal edge regions 26 and 28 is formed. These longitudinal edge regions 26, 28 are in the pack 10 folded state with each other glued. Along the length between the longitudinal seam fin 24 and the lower and upper areas 20, 22 of the front existing bending edge 30 is the longitudinal seam fin 24 - in Fig. 1 down - present folded over. This longitudinal seam fin 24 also extends the two end faces 32 of the pack 10 around and is there on the front seam fins present there 34 attached.

    Zum Herstellen der Faltpackung 10 wird die Folienbahn 12 in ihren Längsrandbereichen 26 bzw. 28, d. h. in ihren an die Biegekante 30 sich querschnittsmäßig nach außen anschließenden Randbereichen mit einer Klebeschicht 40 bzw. 42 versehen. Der Bereich zwischen den beiden in Längsrichtung L sich erst:reckenden Biegekanten 30 (Fig. 3) bildet den inneren Bereich, der direkt an dem zu verpackenden Gut anliegt und der daher nicht mit einer Klebeschicht versehen ist.The film web is used to produce the folding pack 10 12 in their longitudinal edge areas 26 and 28, d. H. in their cross section to the bending edge 30 border areas adjoining the outside provided with an adhesive layer 40 or 42. The area between the two in the longitudinal direction L: stretching Bending edges 30 (Fig. 3) forms the inner Area directly on the goods to be packaged is applied and therefore does not have an adhesive layer is.

    In Fig. 3 ist die Folienbahn 12 mit ihrer Außenseite, so wie sie auf der Packung 10 sichtbar ist, dargestellt. Die Klebeschichten 40, 42 befinden sich dann auf der Unterseite und wären nach der Darstellung gemäß Fig. 3 nicht sichtbar.In Fig. 3 the film web 12 is with its outside, as shown on the package 10. The adhesive layers 40, 42 are then located on the bottom and would be as shown 3 not visible.

    Innerhalb der Klebeschicht 40 des - in Fig. 3 linken - Längsrandbereichs 26, der bei der Darstellung gemäß Fig. 1 als oberer Randbereich sicht bar ist, ist ein etwa halbkreisförmiger Teilbereich 50 von der Klebeschicht 40 ausgespart. Der Teilbereich 50 wird zur Außenkante 52 hin umrahmt durch eine etwa halbkreisförmige Umrißlinie 54, längs der die Folienbahn 12 aufgeschnitten ist. Diese Umrißlinie 54 stellt damit eine Schnitt- bzw. Stanzlinie dar. Der Teilbereich 50 bildet somit eine Lasche, die durch Aufbiegen dieses Teilbereichs 50 aus der Ebene der übrigen Folienbahn 12 entsteht. Die beim Aufklappen dieses Teilbereichs ausgebildete Biegelinie 55 verläuft etwa parallel zur Biegekante 30. Auch im Zwischenbereich 56 zwischen der Biegelinie 55 und der Biegekante 30 ist die Klebeschicht 40 vorhanden. Die Klebeschicht 40 ist mit ihrer Längsstruktur 41 dabei so ausgerichtet, daß die Längsstruktur parallel zur Aufreißrichtung der Packung 10, d. h. parallel zu den Pfeilen 58 verläuft. Dies läßt sich durch entsprechende Auftragsrichtung der Klebeschicht 40 auf der Folienbahn erreichen. Dadurch läßt sich der Teilbereich 50 leicht in Richtung 58 über den Zwischenbereich 56 hinweg aufreißen und damit die Packung 10 öffnen.Within the adhesive layer 40 of the - in Fig. 3 left - Longitudinal edge region 26, which in the illustration 1 as the upper edge area is visible an approximately semicircular portion 50 of the adhesive layer 40 cut out. Subarea 50 becomes Outer edge 52 framed by an approximately semicircular Outline 54, along which the film web 12 is cut open. This outline 54 thus represents represents a cutting or punching line. The partial area 50 thus forms a tab by bending this Partial area 50 from the level of the remaining film web 12 arises. The opening of this section trained bending line 55 runs approximately parallel to the bending edge 30. Also in the intermediate area 56 between the bending line 55 and the bending edge 30 the adhesive layer 40 is present. The adhesive layer 40 is aligned with its longitudinal structure 41 so that the longitudinal structure parallel to the tear direction of the Pack 10, d. H. runs parallel to the arrows 58. This can be done by applying the appropriate direction reach the adhesive layer 40 on the film web. This allows the partial area 50 to be easily moved in the direction 58 tear over the intermediate area 56 and thus open the package 10.

    Der auf der Packung 10 unterhalb des Teilbereiches 50 vorhandene Teilbereich 60 des anderen Längsrandbereiches 28 ist ebenfalls nicht mit einer Klebeschicht versehen, während der übrige Längsrandbereich 28, um den Teilbereich 60 herum, mit der Klebeschicht 42 versehen ist. Auch diese Klebeschicht 42 ist bei der Darstellung gemäß Fig. 3 auf der Unterseite der Folienbahn 12 vorhanden. Durch den klebeschichtfreien Teilbereich 60 läßt sich im zusammengefalteten Zustand der Folienbahn 12 der Teilbereich 50 von dem Teilbereich 60 wegbewegen, was zum Aufreißen der Packung 10 erforderlich ist.The one on the pack 10 below the section 50 existing partial area 60 of the other Longitudinal edge area 28 is also not one Provide adhesive layer, while the rest of the longitudinal edge area 28, around the partial area 60 with which Adhesive layer 42 is provided. This adhesive layer too 42 is in the representation according to FIG. 3 on the Underside of the film web 12 available. By the Partial area 60 free of adhesive layer can be folded up Condition of the film web 12 of the partial area 50 move away from portion 60 what to tear the package 10 is required.

    Im unteren Teilbereich der Längsrandbereiche 26, 28 der Fig. 3 ist eine andere Ausbildungsart für eine Laschenausbildung gezeigt, die nicht unter die Erfindung fällt. Der Teilbereich 50 wird nicht durch eine halbkreisförmige Umrißlinie 54 sondern durch zwei voneinander beabstandete Schnittlinien 70 im Längsrandbereich 26 gebildet, die von der Außenkante 52 in den mit Klebeschicht 40 versehenen Längsrandbereich 26 teilweise hineinragen. Der Teilbereich 72 zwischen diesen Schnittlinien 70 entspricht wirkungsmäßig dem Teilbereich 50. Dementsprechend ist auf dem Längsrandbereich 28 ebenfalls ein dem Teilbereich 60 wirkungsmäßig entsprechender Teilbereich 74 von der Klebeschicht 42 ausgespart. Dieser Teilbereich 74 ist mindestens so groß wie der Teilbereich 72, damit der Teilbereich 72 in seiner Funktion als Lasche von dem Teilbereich 74 wegbewegt und die Packung 10 entsprechend aufgerissen werden kann. Die Aufreißbewegung verläuft ebenfalls wieder parallel zu den Pfeilen 58.In the lower part of the longitudinal edge areas 26, 28 of Fig. 3 is another type of training for a Tab training shown that does not fall under the invention. The partial area 50 is not marked by a semicircular outline 54 but by two cutting lines 70 spaced apart from one another in the longitudinal edge region 26 formed by the outer edge 52 in the longitudinal edge area provided with adhesive layer 40 26 partially protrude. The section 72 between this cutting lines 70 corresponds in terms of effectiveness sub-area 50. Accordingly, on the Longitudinal edge area 28 also a part of the area 60 sub-area 74 corresponding to the effect recessed from the adhesive layer 42. This section 74 is at least as large as the partial area 72, thus the sub-area 72 in its function as a tab moved away from portion 74 and the pack 10 can be torn open accordingly. The tearing movement again runs parallel to arrows 58.
