Description

Die Erfindung betrifft eine Faltschachtel, insbesondere für körniges, rieselfähiges Schüttgut mit den Merkmalen des Oberbegriffs von Patentanspruch 1.The invention relates to a folding box, in particular for granular, free-flowing bulk goods with the features of the preamble of claim 1.

Faltschachteln werden in der Regel zum Verpacken von Schüttgut, wie Reis, Zucker, Salz, Grieß usw., sowie für pulverförmiges Waschmittel oder dergleichen schüttfähiges Gut, verwendet. Solche Faltschachteln weisen an einer Schachtelschmalseite eine Schüttöffnung auf, die über eine Schütte, die aus dem Schachtelinnenraum herausziehbar ist, geöffnet und durch Eindrücken dieser Schütte wieder verschlossen wird.Folding boxes are generally used for packaging bulk goods, such as rice, sugar, salt, semolina, etc., as well as for powdered detergents or similar bulk goods. Such folding boxes have a pouring opening on a narrow side of the box, which opening is opened via a chute which can be pulled out of the interior of the box and is closed again by pressing in this chute.

Inbesondere bei feinkörnigem Schüttgut hat sich herausgestellt, daß dasselbe auch bei orginalverschlossener Faltschachtel ausrieseln kann. Insbesondere bei Pulver können hierdurch nicht nur beachtliche Verluste des Schachtelinhalts eintreten, sondern es muß auch mit einer erheblichen Verschmutzung des Schachtelkörpers, des Umfeldes der Schachtel sowie des Benutzers gerechnet werden.In particular in the case of fine-grained bulk goods, it has been found that the same can trickle out even in the case of an originally closed folding box. In the case of powder in particular, this can result in not only considerable losses in the contents of the box occur, but also significant contamination of the box body, the environment of the box and the user must be expected.

Bei solchen druckschriftlich nicht belegbaren Faltschachteln wurde eine Abhilfe dadurch erzielt, daß an der originalverschlossenen Schachtel die Schütte mit einem Sicherheitsetikett überklebt wurde, wodurch verhindert werden konnte, daß beim Transport und bei der Lagerhaltung vorzeitig der Packungsinhalt neben der Schütte aus einem Spalt ausströmen konnte.In the case of such folding boxes that could not be documented in writing, a remedy was achieved by covering the box with a security label on the originally closed box, which prevented the contents of the package from leaking out of a gap next to the box during transport and storage.

Diese Maßnahme erforderte jedoch zusätzliche Arbeitsgänge zur Herstellung und Anbringung des Sicherheitsetiketts, welches darüber hinaus auch für das Öffnen der Schachtel als störend empfunden sowie hierdurch der optische Gesamteindruck der Schachtel beeinträchtigt wurde.However, this measure required additional work steps for the production and application of the security label, which was also found to be disruptive for opening the box and thereby impaired the overall visual impression of the box.

Diese Nachteile konnten durch eine Faltschachtel in einer Ausbildung gemäß dem Oberbegriff des Anspruches 1 vermieden werden, die Gegenstand der EP-A-0 200 018 ist.These disadvantages could be avoided by a folding box in an embodiment according to the preamble of claim 1, which is the subject of EP-A-0 200 018.

Bei dieser Faltschachtel weist die in Ruhestellung in den Schachtelinnenraum eingeschobene und aus diesem in eine Schüttstellung herausziehbare Schütte zwei Flügel auf. Der eine Flügel ist dreieckförmig und über seine zur Schachtelwand diagonal verlaufende Längskante mit dem Schachtelkörper schwenkbar verbunden, während der andere Schüttenflügel innerhalb des Schachtelkörpers in einer Führungsausnehmung verschieblich geführt ist, die sich zwischen einer Doppelwand des Schachtelkörpers befindet.In the case of this folding box, the chute which is pushed into the interior of the box in the rest position and can be pulled out of it into a pouring position has two wings. One wing is triangular and pivotally connected to the box body via its longitudinal edge diagonally to the box wall, while the other spout wing is slidably guided within the box body in a guide recess which is located between a double wall of the box body.

Der eine Wandteil dieser Doppelwand ist durch Falzen in zwei aneinander anliegende und miteinander verklebte Längsstreifen umgeformt. Der eine Längsstreifen enthält hierbei die Führungsausnehmung und ist an seiner einen Flachseite abgedeckt, so daß dessen Führungsausnehmung von dieser Flachseite her gleichfalls überdeckt ist. Diese Überdeckung ist mit Hilfe des anderen Längsstreifens durch Umklappen und Ankleben desselben an die Flachseite des die Führungsausnehmung aufweisenden Längsstreifens gebildet.One wall part of this double wall is made by folding it into two longitudinal strips that lie against one another and are glued together reshaped. The one longitudinal strip here contains the guide recess and is covered on its one flat side, so that its guide recess is also covered from this flat side. This overlap is formed with the help of the other longitudinal strip by folding it over and gluing it to the flat side of the longitudinal strip having the guide recess.

Auf die andere Flachseite des die Führungsausnehmung aufweisenden Längsstreifens und somit ebenfalls wieder dessen Führungsausnehmung überdeckend ist ein den anderen Wandteil der Doppelwand bildender Abdeckteil aufgeklebt. Dieser Abdeckteil ist durch die eine Seitenwand der Faltschachtel selbst gebildet.A cover part forming the other wall part of the double wall is glued onto the other flat side of the longitudinal strip which has the guide recess and thus also again covers its guide recess. This cover part is formed by the one side wall of the folding box itself.

Die Führungsausnehmung ist somit beidseitig durch Wandungen begrenzt, so daß der Schachtelinhalt daran gehindert ist, in diese einströmen und von dort aus ins Freie ausfließen bzw. ausrieseln zu können.The guide recess is thus delimited on both sides by walls, so that the contents of the box are prevented from flowing into them and from there being able to flow out or trickle out.

Voraussetzung dafür ist allerdings, daß die Führungsausnehmung im Schachtelinnern vor dem die beiden Längsstreifen miteinander verbindenden Falz endet, wodurch die Tiefe der Führungsausnehmung und somit die Länge des in dieser geführten Schüttenflügels entsprechend kurz auszubilden ist, um die Führungsausnehmung an ihrem hinteren Ende geschlossen zu halten.The prerequisite for this, however, is that the guide recess in the interior of the box ends in front of the fold connecting the two longitudinal strips, as a result of which the depth of the guide recess and thus the length of the chute wing guided therein must be made correspondingly short in order to keep the guide recess closed at its rear end.

Dies hat im Falle relativ schmal auszubildender Schachteln den Nachteil, daß dadurch die Schachtelöffnung bei geöffneter Schütte nur entsprechend klein ausfällt.In the case of relatively narrow boxes, this has the disadvantage that the box opening is only correspondingly small when the chute is open.

Die Erfindung befaßt sich mit einer Weiterbildung einer Faltschachtel der im Oberbegriff des Anspruches 1 erläuterten Art, deren Aufgabe gleichfalls darin zu sehen ist, eine abgedichtete Führung des einen Flügels der Schütte in der Führungsausnehmung zu gewährleisten, die für das optiche Erscheinungsbild und den ästhetischen Gesamteindruck der Faltschachtel nicht störend wirkt.The invention relates to a development of a folding box of the type explained in the preamble of claim 1, the task of which is also to be seen therein, a to ensure sealed guidance of one wing of the chute in the guide recess, which does not interfere with the visual appearance and the overall aesthetic impression of the folding box.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 und bei einem Zuschnitt für eine solche Faltschachtel durch die kennzeichnenden Merkmale des Anspruches 4 gelöst.This object is achieved according to the invention by the characterizing features of claim 1 and, in the case of a blank for such a folding box, by the characterizing features of claim 4.

Die erfindungsgemäß vorgesehene Membran verschließt somit zusammen mit dem einen Längsstreifen des einen Wandteils der Doppelwand die Führungsausnehmung auf beiden Seiten, so daß der Schachtelinnenraum gegenüber der Schachtelumgebung vollständig abgeschlossen ist. Eine größtmögliche Tiefe der Führungsausnehmung bzw. eine dementsprechende Länge des in ihr geführten Schüttenflügels läßt sich gemäß Anspruch 2 erzielen.The membrane provided according to the invention thus closes the guide recess on both sides together with the one longitudinal strip of one wall part of the double wall, so that the interior of the box is completely sealed off from the surroundings of the box. A greatest possible depth of the guide recess or a corresponding length of the chute wing guided in it can be achieved according to claim 2.

Eine weitere Ausgestaltung der Erfindung ist Gegenstand des Anspruches 3. Für den Fall, daß hierbei die Faltschachtel mit einer Innenbeschichtung versehen ist, kann im Falle einer aus Folie bestehenden Membran diese Folie ebenfalls aus dem Beschichtungsmaterial bestehen.A further embodiment of the invention is the subject of claim 3. In the event that the folding box is provided with an inner coating, in the case of a membrane consisting of film, this film can also consist of the coating material.

Dadurch, daß beim erfindungsgemäßen Zuschnitt auf dessen die Außenseite der Faltschachtel bildende Oberfläche eine die Führungsausnehmung überdeckende Membran aufgesetzt ist, wird eine einfache Herstellung der Faltschachtel erreicht, indem die Membran bereits bei der Herstellung des Schachtelzuschnittes auf diesen aufgelegt und mit diesem verbunden werden kann.The fact that in the blank according to the invention a membrane covering the guide recess is placed on the surface of the outside of the folding box, simple manufacture of the folding box is achieved in that the membrane can be placed on and connected to the blank during the production of the box blank.

Faltschachtelzuschnitte können somit bereits vom Hersteller derselben mit aufgeklebter Membran geliefert werden, so daß der Abfüllbetrieb lediglich das Schüttgut abzufüllen und die Verpackung zu verschließen hat.Folding box blanks can thus already be supplied by the manufacturer with the membrane attached, so that the bottling company only has to fill the bulk goods and close the packaging.

Ein weiteres Abdichten der Führungsausnehmung wird eine Ausgestaltung des Zuschnittes gemäß den Ansprüchen 5 und 6 erreicht.A further sealing of the guide recess is achieved in a configuration of the blank according to claims 5 and 6.

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung, in der unter Bezugnahme auf die Zeichnung ein besonders bevorzugtes Ausführungsbeispiel im einzelnen beschrieben ist. Die in der Zeichnung dargestellten und in der Beschreibung aufgeführten Merkmale können sowohl jeweils einzeln für sich oder in beliebiger Kombination bei der Erfindung verwirklicht sein.

Bei der in Figur 1 perspektivischen Darstellung ist ein Abschnitt einer insgesamt mit 1 bezeichneten Faltschachtel erkennbar. Von dieser Faltschachtel 1 sind eine Seitenwand 2, eine Schmalseite 3 und ein Deckel 4 erkennbar. Die Seitenwand 2 ist aufgebrochen dargestellt. Es ist daher eine eine Doppelwand 5 bildende Seitenlasche 6 erkennbar, die an der Innenfläche 7 (Fig. 2) anliegt. Die Schmalseite 3 ist mit einer Schüttöffnung 8 sowie einer die Schüttöffnung 8 umgebende Schütte 9 versehen. Die Schütte 9 weist im wesentlichen zwei dreieckförmige Flügel 10 und 11 auf, von denen einer über seine eine Längskante 12 schwenkbar mit der Schmalseite 3 verbunden ist. Diese Längskante 12 erstreckt sich diagonal über die Schmalseite 3 und endet an einem die Schmalseite 3 mit der Seitenlasche 6 verbindenden Falz 13. Der zweite Flügel 11 ist über seine eine Längskante 14 mit dem ersten Flügel 10 verschwenkbar verbunden und weist an der dem Schachtelkörper zugewandten Längskante 15 eine Führungsnase 16 auf. Diese Führungsnase 16 gleitet an einer Führungsfläche 17 entlang und stützt sich dabei in Schüttstellung sich befindender Schütte 9 an einem Anschlag 18 ab. Die Führungsfläche 17 sowie der Anschlag 18 sind Teile einer Führungsausnehmung 19, die in der Schließstellung der Schütte 9 den Flügel 11 vollständig aufnimmt. Dabei liegt die Längskante 15 an einem Anschlag 20 an, durch die die Ruhelage der Schütte 9 definiert ist.In the perspective illustration in FIG. 1, a section of a folding box designated overall by 1 can be seen. A side wall 2, a narrow side 3 and a cover 4 can be seen from this folding box 1. The side wall 2 is shown broken. A side flap 6 forming a double wall 5 can therefore be seen, which abuts the inner surface 7 (FIG. 2). The narrow side 3 is provided with a pouring opening 8 and a chute 9 surrounding the pouring opening 8. The chute 9 has essentially two triangular wings 10 and 11, one of which is pivotally connected to the narrow side 3 via its one longitudinal edge 12. This longitudinal edge 12 extends diagonally across the narrow side 3 and ends at a fold 13 connecting the narrow side 3 with the side flap 6. The second wing 11 is pivotably connected to the first wing 10 via its one longitudinal edge 14 and points at the longitudinal edge facing the box body 15 a guide lug 16. This guide nose 16 slides along a guide surface 17 and is supported in the pouring position of the chute 9 from a stop 18. The guide surface 17 and the stop 18 are parts of a guide recess 19 which completely receives the wing 11 in the closed position of the chute 9. The longitudinal edge 15 bears against a stop 20 by which the rest position of the chute 9 is defined.

Ferner ist in Fig. 1 eine Membrane 21 dargestellt, die zur besseren Erkennbarkeit schraffiert wiedergegeben ist. Diese Membrane 21 überdeckt die Führungsausnehmung 19 vollständig, so daß der Anschlag 18, die Führungsfläche 17 sowie der Anschlag 20 von der Membrane 21 übergriffen ist. Die Führungsfläche 17 und der Anschlag 20 bilden ein hinteres offenes Ende 22 der Führungsausnehmung 19, welches ebenfalls von der Membrane 21 überdeckt ist. Wie aus Fig. 3, in der ein Ausschnitt des Faltschachtelzuschnitts dargestellt ist, zu erkennen ist, umgreift die Membrane 21 nicht nur die in Fig. 1 sichtbare Seite der Seitenlasche 6, sondern auch die vom Betrachter abgewandte und dem Schachtelinnenraum zugewandte Fläche der Seitenlasche 6. Hierdurch wird bewirkt, daß das offene Ende 22 durch die Membrane 21 verschlossen ist.Furthermore, a membrane 21 is shown in FIG. 1, which is shown hatched for better visibility. This membrane 21 completely covers the guide recess 19, so that the stop 18, the guide surface 17 and the stop 20 are overlapped by the membrane 21. The guide surface 17 and the stop 20 form a rear open end 22 of the guide recess 19, which is also covered by the membrane 21. As can be seen from FIG. 3, in which a section of the folding box blank is shown, the membrane 21 encompasses not only the side of the side flap 6 visible in FIG. 1, but also the surface of the side flap 6 facing away from the viewer and facing the interior of the box This causes the open end 22 to be closed by the membrane 21.

Außerdem ist der in Fig. 1 schraffiert wiedergegebene Teil der Membrane 21 z.B. mittels eines Klebstoffs mit der Innenfläche der Seitenwand 2 verklebt, so daß das Schüttgut davon abgehalten wird, zwischen die Seitenlasche 6 und die Seitenwand 2 einzutreten.In addition, the part of the membrane 21 shown hatched in Fig. 1 is e.g. glued to the inner surface of the side wall 2 by means of an adhesive, so that the bulk material is prevented from entering between the side flap 6 and the side wall 2.

Der Flügel 11 weist außerdem Prägelinien 23 auf, die bei eingeschobener Schütte 9 durch die Aussparung 24 mit dem Daumen ergriffen werden können und dadurch die Schütte 9 aus ihrer Ruhelage in die herausgezogene Schüttstellung bringbar ist.The wing 11 also has embossing lines 23 which can be gripped with the thumb 24 through the recess 24 when the chute 9 is inserted, and as a result the chute 9 can be brought out of its rest position into the pulled-out pouring position.

Der in Fig. 2 wiedergegebene Faltschachtelzuschnitt 25 weist eine über einen Falz 26 mit der Seitenwand 2 verbundene Schmalseite 27 und über einen Falz 28 eine weitere Seitenwand 29 auf, an die sich über einen Falz 30 die Schmalseite 3 anschließt. Die Seitenlasche 6, die über den Falz 13 mit der Schmalseite 3 verbunden ist, ist selbst mit einem Falz 31 versehen, der die Seitenlasche 6 in etwa zwei gleich breite Längsstreifen 32 und 33 unterteilt. Die Seitenwände 2 und 29 sind mit Deckel- bzw. Bodenlaschen 34 und 35 bzw. 36 und 37 versehen, und die Schmalseiten 3 und 27 sind mit Umlegelaschen 38, 39 und 40, 41 ausgestattet. Werden die Deckellaschen, Bodenlaschen und Umlegelaschen 34 bis 41 aufeinander umgelegt, so bilden sie den Deckel 4 und einen nicht dargestellten Boden der Faltschachtel 1.The folding box blank 25 shown in FIG. 2 has a narrow side 27 connected to the side wall 2 via a fold 26 and a further side wall 29 via a fold 28, to which the narrow side 3 is connected via a fold 30. The side flap 6, which is connected to the narrow side 3 via the fold 13, is itself provided with a fold 31 which divides the side flap 6 into approximately two longitudinal strips 32 and 33 of the same width. The side walls 2 and 29 are provided with cover or bottom flaps 34 and 35 or 36 and 37, and the narrow sides 3 and 27 are equipped with folding flaps 38, 39 and 40, 41. If the cover flaps, bottom flaps and flap flaps 34 to 41 are folded over on one another, they form the cover 4 and a base (not shown) of the folding box 1.

In Fig. 2 ist die Kontur der Aussparung 24 erkennbar, die in der Seitenwand 2 bzw. an deren Kante vorgesehen ist. Ferner ist erkennbar, daß der Flügel 11 aus dem Längsstreifen 32 ausgeschnitten ist. Zwischen dem Flügel 11, dem offenen Ende 22, welches mit dem Falz fluchtet, der Führungsfläche 17 und dem Anschlag 18 ist eine Ausnehmung ausgestanzt, in der die Führungsnase 16 wandert. Ferner ist zu erkennen, daß die obere, horizontale Kante 42 über Perforationsstreifen mit der Schmalseite 3 verbunden ist. Die Längskanten 12 und 14 sind als Falze ausgebildet, so daß sich beim Betätigen der Schütte 9 der Flügel 10 aus der Ebene der Schmalseite 3 herausbewegen kann. Beim erstmaligen Öffnen der Faltschachtel 1 reißt die Perforation der oberen Kante 42 ein, und die Schüttöffnung 8, die einen dem Flügel 10 entsprechenden Querschnitt aufweist, ist frei.2, the contour of the recess 24 can be seen, which is provided in the side wall 2 or at the edge thereof. It can also be seen that the wing 11 is cut out of the longitudinal strip 32. Between the wing 11, the open end 22, which is flush with the fold, the guide surface 17 and the stop 18, a recess is punched out, in which the guide lug 16 moves. It can also be seen that the upper, horizontal edge 42 is connected to the narrow side 3 via perforation strips. The longitudinal edges 12 and 14 are formed as folds, so that the wing 10 can move out of the plane of the narrow side 3 when the chute 9 is actuated. When the folding box 1 is opened for the first time, the perforation of the upper edge 42 tears, and the pouring opening 8, which has a cross section corresponding to the wing 10, is free.

Durch ein Punktmuster sind auf dem Längsstreifen 32 und der Seitenwand 2 Klebestreifen 43 und 44 angedeutet, auf denen ein geeigneter Haftvermittler, z.B. ein Heißkleber, ein druckaktiver Kleber o. dgl. aufgetragen ist. Über den Klebestreifen 43 wird der Längsstreifen 33 mit dem Längsstreifen 32 verbunden, so daß die Führungsausnehmung 19 von dieser Seite verdeckt ist. Über den Klebestreifen 44 wird unter Zwischenschaltung der Membrane 21, wie aus Fig. 3 deutlicher erkennbar ist, die in Fig. 2 vom Betrachter abgewandte Rückseite des Längsstreifens 32 an der Seitenwand 2 festgelegt. Hierdurch wird die Schachtelhülse gebildet, so daß der Faltschachtelzuschnitt 25 aufgerichtet werden kann.Adhesive strips 43 and 44 are indicated by a dot pattern on the longitudinal strip 32 and the side wall, on which a suitable adhesion promoter, e.g. a hot melt adhesive, a pressure sensitive adhesive or the like is applied. The longitudinal strip 33 is connected to the longitudinal strip 32 via the adhesive strip 43, so that the guide recess 19 is covered from this side. The rear side of the longitudinal strip 32 facing away from the viewer in FIG. 2 is fixed on the side wall 2 via the adhesive strip 44 with the membrane 21 interposed, as can be seen more clearly from FIG. 3. As a result, the box sleeve is formed so that the folding box blank 25 can be erected.

Die Anordnung der Membrane 21 an der in Fig. 3 dem Betrachter zugewandten Rückseite des Faltschachtelzuschnitts 25, der bei aufgerichtetem Zuschnitt die außenoberfläche der Faltschachtel 1 bildet, ist aus Fig. 3 deutlich erkennbar. Die Membrane 21 erstreckt sich über die ganze Breite des Längsstreifens 33 und nahezu über die ganze Breite des Längsstreifens 32, wobei die linke Kante sich in geringem Abstand vom Falz 13 befindet. Dies ist erforderlich, um die Prägelinien 23, die aus der Aussparung 24 hervortreten, freizuhalten.The arrangement of the membrane 21 on the rear side of the folding box blank 25 facing the viewer in FIG. 3, which forms the outer surface of the folding box 1 when the blank is erected, can be clearly seen from FIG. 3. The membrane 21 extends over the entire width of the longitudinal strip 33 and almost over the entire width of the longitudinal strip 32, the left edge being at a short distance from the fold 13. This is necessary in order to keep the embossing lines 23, which emerge from the recess 24, free.

In Längsrichtung der Faltschachtel 1 erstreckt sich die Membrane 21 wenigstens über die ganze Länge der Führungsausnehmung 19 inklusive des Flügels 11. Hierdurch wird gewährleistet, daß auch von dieser Seite die Führungsausnehmung 19 abgedichtet ist. Da sich die Membrane 21 vom Längsstreifen 32 über den Falz 31 zum Längs streifen 33 erstreckt, wird auch das offene Ende 22 beim Umklappen und Ankleben des Längsstreifens 33 auf den Längsstreifen 32 verschlossen. Es kann somit keinerlei Schüttgut über die Führungsausnehmung 19 austreten, da diese auf ihrer einen Seite vom Längsstreifen 33 und auf ihrer anderen Seite von der Membrane 21 übergriffen und dadurch abgedichtet ist. Ferner ist der Abschnitt der Membrane 21, der sich auf dem Längsstreifen 32 befindet, über den Klebestreifen 44 mit der Seitenwand 2 dichtend verbunden.In the longitudinal direction of the folding box 1, the membrane 21 extends at least over the entire length of the guide recess 19 including the wing 11. This ensures that the guide recess 19 is also sealed from this side. Since the membrane 21 extends from the longitudinal strip 32 over the fold 31 to the longitudinal strip 33, the open end 22 is also when the longitudinal strip 33 is folded over and glued to the longitudinal strip 32 locked. No bulk material can thus exit via the guide recess 19, since this is overlapped on one side by the longitudinal strip 33 and on the other side by the membrane 21 and is thereby sealed. Furthermore, the section of the membrane 21, which is located on the longitudinal strip 32, is sealingly connected to the side wall 2 via the adhesive strip 44.

Diese Erfindung hat den Vorteil, daß aus dem Schachtelinnenraum bei verschlossener Schütte 9 keinerlei Schüttgut nach außen austreten kann. Außerdem wird das ästhetische Erscheinungsbild der Faltschachtel 1 weder durch außen aufgeklebte Sicherheitsetiketten o. dgl. nachteilig beeinflußt. Schließlich bedarf es nach dem Abfüllen und Verschließen der Faltschachtel keines zusätzlichen Arbeitsschrittes zum Aufbringen eines Sicherheitsetiketts, so daß der Arbeitsablauf in den Abfüllbetrieben abgekürzt ist. Die Faltschachtel 1 kann in zusammengelegtem Zustand mit aufgebrachter Membrane 21 direkt vom Faltschachtel-Hersteller zum Abfüllbetrieb geliefert und dort wie übliche Faltschachteln gehandhabt werden.This invention has the advantage that no bulk material can escape from the inside of the box when the chute 9 is closed. In addition, the aesthetic appearance of the folding box 1 is neither adversely affected by security labels or the like stuck on the outside. Finally, after the folding box has been filled and closed, no additional work step is required to apply a security label, so that the workflow in the bottling plants is shortened. The folded box 1 can be delivered in the folded state with the membrane 21 applied directly from the folding box manufacturer to the bottling plant and can be handled there as usual folding boxes.
