Abstract

The folding box has a rectangular bottom surface and side walls and end walls attached thereto. Provided between the latter are gusset corners which can be folded onto the outside of the end walls. The folding line of these gusset corners is arranged off-centre, by which means the folding box is braced when it is set up, which holds the folding box firmly in its upright state. <IMAGE>

Description

Die Erfindung betrifft eine schalenförmige Faltschachtel mit einer vorzugsweise rechteckigen Bodenfläche sowie an deren Begrenzungskanten angelenkten Seiten- und Stirnwänden und zwischen diesen befindlichen Zwickelecken, die beim Aufrich­ten der Faltschachtel paarweise und in sich gefaltet auf die Außenseite der Stirnwände aufgefaltet sind.The invention relates to a bowl-shaped folding box with a preferably rectangular bottom surface and hinged to the boundary edges of the side and end walls and gusset corners located between them, which are folded in pairs and when folded up on the outside of the end walls when the folding box is erected.

Bei einer aus dem DE-GM 81 20 990 bekannten schalenförmigen Faltschachtel dieser Art müssen die Zwickelecken an den Stirnwänden festgeklebt werden, um ein Aufgehen der Falt­schachtel zu verhindern.In a bowl-shaped folding box of this type known from DE-GM 81 20 990, the gusset corners must be glued to the end walls in order to prevent the folding box from opening.

Der Erfindung liegt die Aufgabe zugrunde, eine derartige Faltschachtel so auszugestalten, daß sie nach dem Aufrichten selbständig stabil ist und einer Klebung nicht unbedingt bedarf.The invention has for its object to design such a folding box so that it is automatically stable after erection and does not necessarily require gluing.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die die Zwickelecken unterteilende Faltlinie geringfügig gegen­über der Winkelhalbierenden versetzt angeordnet ist, wodurch beim Auffalten der Zwickelecken auf die Außenseite der Stirnwand diese geringfügig ins Innere der Faltschachtel gezogen wird, wobei ihre seitliche Begrenzungskante inner­halb der Begrenzungslinie der benachbarten Seitenwand an deren Innenfläche anliegt, und daß die Stirnwand auf deren Außenseite die Zwickelecken aufgefaltet werden, an ihrem oberen Rand mit einer vorzugsweise über deren ganze Breite reichenden Klappe versehen ist, welche auf die Außenseite gefaltet ist und die Zwickelecken zwischen sich und der Stirnwand einklemmt.This object is achieved in that the fold line dividing the gusset corners is arranged slightly offset from the bisector of the angle, so that when the gusset corners are unfolded onto the outside of the end wall, it is pulled slightly into the inside of the folding box, its lateral boundary edge within the boundary line of the adjacent side wall bears on the inner surface thereof, and that the end wall on the outside of which the gusset corners are unfolded, at its upper edge, preferably over its entire width is provided flap which is folded on the outside and clamps the gusset corners between itself and the end wall.

Durch diese Ausgestaltung der schalenförmigen Faltschachtel bleibt diese nach dem Aufrichten in ihrer vorgegebenen Stellung, ohne daß es einer zusätzlichen Festlegung der Wände bzw. Wandabschnitte bedarf. Darüber hinaus ist aber auch das Aufrichten der Faltschachtel sehr einfach und kann sowohl maschinell als auch manuell durchgeführt werden.As a result of this configuration of the shell-shaped folding box, it remains in its predetermined position after being erected without the need for additional fixing of the walls or wall sections. In addition, erecting the folding box is very easy and can be carried out both by machine and manually.

Eine vorteilhafte Ausgestaltung der Erfindung liegt darin, daß die Zwickelecken an ihrer freien Ecke eine annähernd rechtwinklige Aussparung aufweisen, wodurch die Begrenzungs­kante der auf die Stirnwand aufgefalteten Zwickelecken etwa senkrecht verläuft.An advantageous embodiment of the invention is that the gusset corners have an approximately rectangular recess at their free corner, so that the boundary edge of the gusset corners unfolded on the end wall is approximately perpendicular.

Dadurch steht die Länge der oberen Begrenzungskante und der schräg verlaufenden unteren Begrenzungskante in einem opti­malen Verhältnis, bei dem gewährleistet ist, daß die obere Begrenzungskante möglichst lang ist, um optimal von der darübergefalteten Klappe gehalten zu werden und die untere schräge Begrenzungskante nur so lang ist, daß keine gegen­seitige Störung mit der benachbarten Zwickelecke stattfin­det.As a result, the length of the upper boundary edge and the obliquely running lower boundary edge is in an optimal ratio, with which it is ensured that the upper boundary edge is as long as possible in order to be optimally held by the flap folded over and the lower oblique boundary edge is only as long, that there is no mutual interference with the neighboring gusset corner.

Sehr vorteilhaft ist es auch, wenn erfindungsgemäß die Stirnwände mit Faltlinien versehen sind, entlang derer die Stirnwände mit ihrem Mittelabschnitt nach außen gedrückt sind.It is also very advantageous if, according to the invention, the end walls are provided with fold lines along which the end walls are pressed outwards with their central section.

Durch die dabei herbeigeführte Verformung, die bleibend ist, wird eine weitere Sicherung gegen ein unbeabsichtigtes Aufgehen der Faltung erzielt.The resulting deformation, which is permanent, provides further protection against unintentional opening of the fold.

Dabei hat es sich als zweckmäßig ergeben, wenn erfindungs­gemäß die Faltlinien der Stirnwände von deren unterem Eck­punkt ausgehen und in einem Winkel nach oben verlaufen, der dem Winkel der Faltlinien der Zwickelecken entspricht.It has been found to be expedient if, according to the invention, the fold lines of the end walls start from their lower corner point and extend at an angle which corresponds to the angle of the fold lines of the gusset corners.

Diese Ausgestaltung erleichtert das nach außen gerichtete Verformen der Stirnwand ganz erheblich und sichert es vor allem.This configuration considerably facilitates the outward deformation of the end wall and, above all, secures it.

Verbessert kann dies noch dadurch werden, daß erfindungsge­mäß in der an der Stirnwand angelenkten Klappe Faltlinien vorgesehen sind, welche die Fortsetzung der Faltlinien in der Stirnwand bilden, aber entgegengesetzt verlaufen.This can be further improved by the fact that, according to the invention, fold lines are provided in the flap hinged to the end wall, which form the continuation of the fold lines in the end wall, but run in opposite directions.

Die Verformung der Faltschachtel kann noch dadurch unter­stützt werden, daß erfindungsgemäß in den Seitenwänden Faltlinien vorgesehen sind, welche von deren unteren Eck­punkten ausgehen, schräg nach oben verlaufen und in geringem Abstand voneinander am oberen Rand der Seitenwände enden.The deformation of the folding box can be supported by the fact that, according to the invention, folding lines are provided in the side walls, starting from their lower corner points, running obliquely upwards and ending at a small distance from one another at the upper edge of the side walls.

Soll bei besonderen Anwendungsfällen für eine als notwendig erachtete zusätzliche Sicherung eine zusätzliche Klebung vorgesehen werden, dann ist es besonders günstig, wenn erfindungsgemäß an der Außenseite der Zwickelecken eine wenigstens annähernd kreisförmige Ritzlinie vorgesehen ist, welche bis etwa zur halben Materialstärke in die Zwickelecke eindringt und im Überdeckungsbereich der an die Stirnwand angelenkten Klappe liegt, und daß auf dem innerhalb dieser Ritzlinie liegenden Abschnitt ein Klebemittel angebracht ist, welches die Klappe mit der Zwickelecke verbindet.If, in special applications, an additional adhesive is to be provided for an additional securing that is deemed necessary, then it is particularly advantageous if, according to the invention, an at least approximately circular scoring line is provided on the outside of the gusset corners, which penetrates into the gusset corner up to approximately half the material thickness and in Cover area of the flap hinged to the end wall, and that an adhesive is attached to the section lying within this score line, which connects the flap to the gusset corner.

Zum Ablösen wird das Material entlang der Ritzlinie aus der Zwickelecke entsprechend der Tiefe der Ritzlinie herausge­löst, was einerseits ein leichtes Auftrennen ermöglicht, andererseits aber doch einen sicheren Halt gewährleistet.To detach the material along the scoring line is released from the gusset corner according to the depth of the scoring line, which on the one hand enables easy separation, but on the other hand ensures a secure hold.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Dabei zeigen:

  • Fig. 1 einen flachliegenden Zuschnitt und
  • Fig. 2 eine fertig aufgerichtete Faltschachtel.
In the drawing, an embodiment of the invention is shown. Show:
  • Fig. 1 shows a flat blank and
  • Fig. 2 shows a fully erected folding box.

Mit 1 ist in Fig. 1 ein flachliegender Zuschnitt bezeichnet, der einen Boden 2 aufweist, an dem einander gegenüberliegend zwei Seitenwände 3 und 4 über Faltlinien 5 und 6 angelenkt sind. An den beiden anderen Begrenzungskanten des Bodens 2 sind über weitere Faltlinien 7 und 8 Stirnwände 9 und 10 angeformt.
Zwischen den Seitenwänden 3 bzw. 4 und den Stirnwänden 9 bzw. 10 sind Zwickelecken 11,12,13 und 14 vorgesehen, die sowohl an der benachbarten Seitenwand als auch an der Stirn­wand über Faltlinien 15 bis 22 angelenkt sind. Die zwischen den Zwickelecken und den Stirnwänden vorgesehenen Faltlinien 15 und 18 bzw. 19 und 22 verlaufen in Verlängerung der Faltlinien 5 bzw. 6 zwischen dem Boden 2 und den beiden Seitenwänden 3 und 4. Die Faltlinien 16 und 21 bzw. 17 und 20 stellen dagegen Verlängerungen der Faltlinien 7 und 8 zwischen dem Boden 2 und den beiden Seitenwänden dar. Die Zwickelecken 11 bis 14 sind jeweils durch eine Faltlinie 23 unterteilt, die mit der Faltlinie 16,17,20,21 gegen die benachbarte Seitenwand hin einen geringfügig kleineren Winkel α einschließt als mit der Faltlinie 15,18,19,22 gegen die benachbarte Stirnwand hin. Der Winkel α beträgt dabei etwa 43 Grad, während der andere Winkel etwa 47 Grad beträgt.1 in FIG. 1 denotes a flat blank which has a base 2 on which two side walls 3 and 4 are hinged opposite one another via fold lines 5 and 6. End walls 9 and 10 are formed on the two other boundary edges of the base 2 via further fold lines 7 and 8.
Between the side walls 3 and 4 and the end walls 9 and 10, gusset corners 11, 12, 13 and 14 are provided, which are articulated both on the adjacent side wall and on the end wall via fold lines 15 to 22. The fold lines 15 and 18 or 19 and 22 provided between the gusset corners and the end walls extend the fold lines 5 and 6 between the bottom 2 and the two side walls 3 and 4. The fold lines 16 and 21 or 17 and 20 represent them Extensions of the fold lines 7 and 8 between the bottom 2 and the two side walls. The gusset corners 11 to 14 are each divided by a fold line 23 which, with the fold line 16, 17, 20, 21, has a slightly smaller angle α against the adjacent side wall includes as with the fold line 15,18,19,22 against the adjacent end wall. The angle α is about 43 degrees, while the other angle is about 47 degrees.

An den beiden Stirnwänden 9 und 10 sind über weitere Falt­linien 27 und 28 Klappen 29,30 angeformt, die über die ganze Breite der Stirnwände reichen.On the two end walls 9 and 10 flaps 29, 30 are formed via further fold lines 27 and 28, which extend over the entire width of the end walls.

In beiden Stirnwänden 9 und 10 sind Faltlinien 31,32 bzw. 33,34 vorgesehen, deren Winkel β mit der Faltlinie 7 bzw. 8 etwa dem Winkel α entspricht. Diese Faltlinien reichen bis zur äußeren Faltlinie 27 bzw. 28 und sind dann in den Klap­pen 29 bzw. 30 in Rillinien 35,36 fortgesetzt, die entgegen­gesetzt verlaufen und mit der Faltlinie 27 bzw. 28 ebenfalls den Winkel β einschließen. An der einen Klappe 30 ist ein bogenförmiger Ansatz 37 angeformt, der als Öffnungshilfe dient. Zur Materialersparnis kann in der gegenüberliegenden Klappe 29 eine entsprechende Aussparung 38 vorgesehen sein.Fold lines 31, 32 and 33, 34 are provided in both end walls 9 and 10, the angle β of which with the fold line 7 and 8 corresponds approximately to the angle α. These fold lines extend to the outer fold line 27 or 28 and are then continued in the flaps 29 or 30 in crease lines 35, 36, which run in opposite directions and also enclose the angle β with the fold line 27 or 28. On one flap 30, an arcuate extension 37 is formed, which serves as an opening aid. A corresponding recess 38 can be provided in the opposite flap 29 to save material.

An dem beim Auffalten außen liegenden Abschnitt der Zwickel­ecken ist durch eine kreisförmige Ritzlinie 39 ein Abschnitt 40 abgeteilt, in dem eine Verklebung mit der Klappe 29 bzw. 30 vorgenommen werden kann. Durch die Verspannung der Falt­schachtel ist eine derartige Verklebung zwar nicht notwen­dig; sie kann jedoch zur Sicherheitserhöhung vorgesehen werden.At the section of the gusset corners which is on the outside when unfolding, a section 40 is divided by a circular scribe line 39, in which a gluing with the flap 29 or 30 can be carried out. Due to the tensioning of the folding box, such gluing is not necessary; however, it can be used to increase security.

In den Seitenwänden 3,4 können Faltlinien 41,42 vorgesehen sein, welche von deren unteren Eckpunkten ausgehen, schräg nach oben verlaufen und in einem Abstand voneinander am oberen Rand der Seitenwände enden.Fold lines 41, 42 can be provided in the side walls 3, 4, starting from their lower corner points, running obliquely upwards and ending at a distance from one another at the upper edge of the side walls.

In Fig. 2 ist eine fertig aufgerichtete Faltschachtel dar­gestellt, deren Wände so gegeneinander verspannt sind, daß ein unbeabsichtigtes Zurückfalten unter normalen Umständen nicht eintreten kann.In Fig. 2 a fully erected folding box is shown, the walls of which are so braced against one another that an unintentional folding back cannot occur under normal circumstances.
