Abstract

The blank possesses an internal bag 16 which, in the finished, folded state, is of square design with four mutually parallel fold lines as the edges of the square and is provided, on mutually opposite sides, with an additional central fold line in each case extending centrally between two of the mutually adjacent fold lines. In this arrangement, the bag 16 inserted in the blank is bonded to the two internal sides of the blank without the central fold lines, at least in some areas, and the blank can be folded, by being turned over at its upper and lower ends, about a transverse fold which extends perpendicularly to the fold lines in each case. The bag 16 is designed as a block-bottomed bag whose flat block bottom 17 is folded downwards in a V-shaped manner along its line of symmetry 20, forming two flat bag sides 18, 19 which are parallel to each other and of equal size. Moreover, each flat bag side 18, 19 is laid flush on one of the interior sides 21, 22 of the blank 5 which lack the central fold lines 12, 13, in a manner such that the lower end 23, 24 of each flat bag side 18, 19 ends at the lower transverse fold 15 of the blank 5. Finally, each flat bag side is attached by bonding, at least in some areas, in the region between the two transverse folds 14, 15 (Fig. 1). <IMAGE>

Description

Die Erfindung betrifft eine Faltschachtel mit eingesetztem inneren Beutel gemäß dem Oberbegriff des Hauptanspruchs.The invention relates to a folding box with an inner bag inserted according to the preamble of the main claim.

Solche Beutel sind bekannt (US-PS 2,250,249). Hierbei werden Faltenbeutel mit einem Flossenboden oder ein Flachbeutel mit einem Kreuzboden in die Faltschachtel eingesetzt.Such bags are known (US Pat. No. 2,250,249). Folded bags with a fin base or a flat bag with a cross bottom are used in the folding box.

Von Nachteil bei diesen bekannten Faltschachteln ist die Tatsache, daß sie sich nicht bei seitlichem Druck auf die Mittelfaltlinie, zumindest nicht gleichmäßig öffnet. Somit scheidet eine automatische Weiterverarbeitung der aufeinandergestapelten flachen Faltschachteln aus. Außerdem ist der Beutel bei der Befüllung stark belastet und bricht häufig auf.A disadvantage of these known folding boxes is the fact that they do not open, at least not evenly, with lateral pressure on the middle folding line. Automatic further processing of the stacked flat folding boxes is therefore ruled out. In addition, the bag is heavily loaded during filling and often breaks open.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine gattungsgemäße Faltschachtel mit eingesetztem inneren Beutel so auszubilden, daß sie zuverlässig dicht ist, automatisch weiter verarbeitet werden kann und beim Öffnen der Faltschachtel sich der Beuteltyp mit bester Volumenausnützung (Klotzbeutel) direkt vollständig - auch im Boden - mitöffnet.The invention is therefore based on the object of designing a generic folding box with an inserted inner bag in such a way that it is reliably tight, can be automatically processed further and when the folding box is opened the bag type with the best volume utilization (block bag) is directly completely - also in the bottom - opened.

Diese Aufgabe wird bei einer gattungsgemäßen Faltschachtel erfindungsgemäß durch deren kennzeichnende Merkmale gelöst. Die spezielle Ausbildung des Blockbodenbeutels und dessen bestimmte Art der Einklebung in die Faltschachtel stellt sicher, daß bei geringstem seitlichen Druck auf die Mittelfaltlinien der Faltschachtel sich diese öffnet, ohne daß eine der Öffnungsbewegung entgegengerichtete Kraft beim gleichzeitigen Auffalten des Blockbodenbeutels wirkt, weil der Blockbodenbeutel im aufgefalteten Zustand vollständig in der Faltschachtel, deren vier Innenseiten und deren Boden fest und ohne Zwischenraum anliegt. Es muß lediglich die zum Auffalten des Beutels erforderliche Kraft aufgebracht werden, so daß sich dieser frei auffalten kann. Der fest und ohne Zwischenraum den Boden und den vier Innenseiten der Faltschachtel dann anliegende aufgefaltete Beutel gibt ferner die bei seiner Befüllung auftretenden Kräfte direkt an die steifere Faltschachtel ab, so daß der innere Beutel hinreichend zuverlässig dicht bleibt und nicht etwa reißt.This object is achieved according to the invention in a generic folding box by its characteristic features. The special design of the block bottom bag and its specific type of gluing into the folding box ensures that with minimal lateral pressure on the center folding lines of the folding box, the latter opens without any force counteracting the opening movement when the block bottom bag is unfolded because the block bottom bag is unfolded Condition completely in the folding box, the four inner sides and the bottom of which are tight and without space. It must only the force required to unfold the bag can be applied so that it can unfold freely. The unfolded bag then firmly and without space in between the bottom and the four inner sides of the folding box also gives off the forces that occur when it is filled, directly to the stiffer folding box, so that the inner bag remains sufficiently reliably sealed and does not tear.
