Abstract

The folding box is made of a single-part cardboard blank with a longitudinal seam and closure flaps arranged at the end faces. Two of these closure flaps overlap each other and are provided with perforation lines, by which means two tear-off strips located one above the other are formed. These tear-off strips take up the entire overlapping region of the two closure flaps, the intention being for this region to be located in the centre of the folding box or to extend over the entire height in the case of relatively flat folding boxes. <IMAGE>

Description

Die Erfindung betrifft eine Faltschachtel, vorzugsweise aus einem einteiligen Kartonzuschnitt, mit einer Längsnaht sowie an beiden Stirnseiten angeordneten Verschlußklappen, von denen sich zwei einander gegenüberliegende wenigstens teilweise überlappen undin denen ein durch Perforation gebildeter Aufreißstreifen vorgesehen ist.The invention relates to a folding box, preferably made of a one-piece cardboard blank, with a longitudinal seam and closure flaps arranged on both end faces, two of which oppose one another at least partially overlap and in which a tear strip formed by perforation is provided.

In der Praxis sind derartige Faltschachteln bekannt, bei denen ein Teil einer der Verschlußklappen durch zwei Perforations-. linien abgeteilt ist, wodurch ein Aufreißstreifen gebildet ist.In practice, folding boxes of this type are known in which a part of one of the closure flaps has two perforations. lines is divided, whereby a tear strip is formed.

Insbesondere bei kleinen Faltschachteln liegt dabei die eine der Perforationslinien sehr nahe an der Anlenklinie der Verschlußklappen. Dadurch wird beim Umfalten der Verschlußklappe zwangsläufig auch die Perforationslinie - wenn auch in geringerem Umfang - verbogen und damit die verbliebenen Stege zwischen den Perforationen gedehnt. Die Festigkeit der Perforationslinie wird damit ganz erheblich reduziert, wobei das Maß der Reduzierung unbekannt ist. Darüber hinaus ist diese Verschlußklappe nicht mehr plan.Especially in the case of small folding boxes, one of the perforation lines is very close to the hinging line of the flaps. As a result, when the flap is folded over, the perforation line is inevitably bent, even if to a lesser extent, and the remaining webs between the perforations are thus stretched. The strength of the perforation line is thus reduced considerably, the extent of the reduction being unknown. In addition, this flap is no longer flat.

Der Erfindung liegt die Aufgabe zugrunde, eine Faltschachtel der eingangs genannten Art so auszugestalten, daß die geschilderten Nachteile vermieden werden.The invention has for its object to design a folding box of the type mentioned in such a way that the disadvantages described are avoided.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der gesamte Uberlappungsbereich der beiden sich gegenseitig überlappenden Verschlußklappen durch jeweils eine Perforation abgeteilt ist.This object is achieved in that the entire overlap area of the two mutually overlapping flaps is divided by a perforation.

Dadurch ergibt sich die Möglichkeit, in Ubereinstimmung mit einer weiteren Ausgestaltung der Erfindung, daß der mit Perforationen abgeteilte Uberlappungsbereich in der Mitte der Faltschachtel angeordnet ist.This results in the possibility, in accordance with a further embodiment of the invention, that the overlap area divided off with perforations is arranged in the middle of the folding box.

Hiermit hat der Abstand zwischen der Anlenklinie und der Perforationslinie der jeweiligen Verschlußklappe das größtmögliche Maß; wodurch die Beeinflussung der Perforationslinie beim Umfalten am geringsten ist.The distance between the articulation line and the perforation line of the respective closure flap hereby has the greatest possible dimension; which has the least impact on the perforation line when folded.

Es ist im Rahmen der Erfindung - insbesondere bei einer verhältnismäßig flachen Faltschachtel - auch möglich, daß sich der Uberlappungsbereich der Verschlußklappen über die gesamte Faltschachtelhöhe erstreckt und die Perforationslinien mit den Anlenklinien der Verschlußklappen zusammenfallen.It is also possible within the scope of the invention - in particular in the case of a relatively flat folding box - that the overlap region of the closure flaps extends over the entire height of the folding box and that the perforation lines coincide with the articulation lines of the closure flaps.

Damit werden zwar die Perforationslinien ebenfalls umgefaltet und gedehnt, diese Dehnung erfolgt jedoch kontrolliert, so daß sie beherrschbar ist.Although the perforation lines are also folded over and stretched, this stretching is controlled so that it can be controlled.

In der Zeichnung ist die Erfindung anhand von zwei Ausführungsbeispielen veranschaulicht.Dabei zeigen:

  • Fig. 1 und 2 zwei flachliegende Kartonzuschnitte.
The invention is illustrated in the drawing using two exemplary embodiments, in which:
  • 1 and 2 two flat cardboard blanks.

Mit 1 ist in Fig. 1 ein Kartonzuschnitt bezeichnet, der eine Deckelwand 2, eine Bodenwand 3 und zwei Seitenwände 4 und 5 aufweist. An der Bodenwand 3 ist ein schmaler Streifen 6 angelenkt, der mit der Seitenwand 4 in einer Längsnaht verbunden wird. Zum Verschließen der beiden Stirnseiten sind an den Wänden Verschlußklappen 7 bis 16 über Faltlinien angelenkt. Die Verschlußklappen 8 und 10 bzw. 13 und 15 sind an Deckelwand 2 bzw. Bodenwand 3 angelenkt und überlappen einander im aufgerichteten Zustand der Faltschachtel geringfügig. Bei den beiden Verschlußklappen 13 und 15 ist dieser Uberlappungsbereich durch jeweils eine Perforationslinie 17 bzw 18, abgeteilt.1 in FIG. 1 denotes a cardboard blank which has a top wall 2, a bottom wall 3 and two side walls 4 and 5. A narrow strip 6 is articulated on the bottom wall 3 and is connected to the side wall 4 in a longitudinal seam. To close the two end faces, flaps 7 to 16 are hinged to the walls via fold lines. The flaps 8 and 10 or 13 and 15 are hinged to the top wall 2 or bottom wall 3 and slightly overlap one another in the erected state of the folding box. In the case of the two closure flaps 13 and 15, this overlap area is divided by a perforation line 17 and 18, respectively.

Zum öffnen der Faltschachtel werden beide durch diese Perforationslinie abgeteilten Aufreißstreifen 19 bzw. 20 abgerissen.To open the folding box, both tear strips 19 and 20 divided by this perforation line are torn off.

Beim Ausführungsbeispiel nach Fig. 2 ist ein Kartonzuschnitt 21 wieder mit Deckelwand 22 und Bodenwand 23 sowie Seitenwänden 24 und 25 sowie einem Streifen 26 ausgestattet. Die Seitenwände 24 und 25 sind dabei sehr schmal ausgebildet, wodurch beim Aufrichten eine verhältnißmäßig flache Faltschachtel entsteht. An den Wänden sind wieder über nicht bezeichnete Faltlinien Verschlußklappen 27 bis 32 und 34, 36 angelenkt.In the exemplary embodiment according to FIG. 2, a cardboard blank 21 is again equipped with a top wall 22 and bottom wall 23 as well as side walls 24 and 25 and a strip 26. The side walls 24 and 25 are made very narrow, which results in a relatively flat folding box when erected. Again flaps 27 to 32 and 34, 36 are hinged to the walls via fold lines (not shown).

An der Deckelwand 22 und der Bodenwand 23 sind zum Öffnen der Faltschachtel eingerichtete Verschlußklappen 33 und 35 angeformt. Dabei sind die Verbindungslinien zwischen diesen beiden Wänden und den Verschlußklappen als Perforationslinien 37 bzw. 38 ausgebildet. Beim Aufrichten des Zuschnittes 21 zu einer Faltschachtel werden die beiden Verschlußklappen entlang dieser Perforationslinien.37 und 38 umgefaltet, so daß sie auch Anlenk- oder Biegelinien darstellen.Sealing flaps 33 and 35 are formed on the top wall 22 and the bottom wall 23 for opening the folding box. The connecting lines between these two walls and the flaps are designed as perforation lines 37 and 38, respectively. When the blank 21 is erected into a folding box, the two flaps are folded over along these perforation lines 37 and 38 so that they also represent articulation or bending lines.
