Description

Die Erfindung bezieht sich auf einen Kartonzuschnitt zum Herstellen einer Faltschachtel, mit einem Boden, zwei Seitenwänden sowie je einer Vorder- und Rückwand, die am Boden angelenkt sind und mit einer an der Rückwand angelenkten Deckwand, wobei die am Boden angelenkten Wände über Zwischenflächen miteinander verbunden sind, die durch jeweils eine Faltlinie unterteilt sind.The invention relates to a cardboard blank for producing a folding box, with a base, two side walls and a front and rear wall, which are articulated on the floor and with a top wall articulated on the rear wall, the walls articulated on the floor being connected to one another via intermediate surfaces are divided by a fold line.

Bei den aus einem derartigen Zuschnitt hergestellten Faltschachteln besteht das Problem, daß ihr Unterteil nicht bis zur vollen Höhe dicht ist.The problem with the folding boxes produced from such a blank is that their lower part is not tight to the full height.

Um eine einwandfreie Einfaltung der Zwickelflächen zu ermöglichen, ist es notwendig, diese unterhalb der Oberkante der Seitenwände bzw. der Vorder- und Rückwand enden zu lassen, wodurch diese Undichtigkeit bedingt ist.In order to enable the gusset surfaces to be folded in properly, it is necessary to allow them to end below the upper edge of the side walls or the front and rear walls, as a result of which this leakage is caused.

Der Erfindung liegt die Aufgabe zugrunde, einen Kartonzuschnitt vorzuschlagen, mit dem eine Faltschachtel hergestellt werden kann, die trotz ihrer guten Auffaltbarkeit ein weitgehend dichtes Unterteil aufweist.The invention is based on the object of proposing a cardboard blank with which a folding box can be produced which, despite its good unfoldability, has a largely sealed lower part.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Zwischenflächen im Bereich einer Seitenwand mit einem spitzwinklig ausgebildeten Ausschnitt versehen sind und die durch die beiden Begrenzungskanten der Zwischenfläche und die diese unterteilende Faltlinie gebildete Spitze mit der Begrenzungskante der benachbarten Seitenwand wenigstens annähernd fluchtet.This object is achieved in that the intermediate surfaces in the region of a side wall are provided with an acute-angled cutout and the is at least approximately aligned with the boundary edge of the adjacent side wall by the two boundary edges of the intermediate surface and the fold line dividing the intermediate surface.

Durch diese konstruktive Ausgestaltung ist das Unterteil der Faltschachtel nach ihrem Aufrichten bis an ihre Oberkante dicht. Vorallem bei einer nur auf der Innenseite vorgesehenen siegelbaren Beschichtung des Kartonmaterials ist diese Ausgestaltung sehr günstig.As a result of this design, the lower part of the folding box is sealed up to its upper edge after it has been erected. This configuration is very favorable, especially if the cardboard material is provided with a sealable coating only on the inside.

Eine vorteilhafte Weiterbildung der Erfindung liegt darin, daß an der Deckwand eine Vorderwandklappe und zwei Seitenwandklappen angelenkt sind, welche die Vorderwand und die beiden Seitenwände im aufgerichteten Zustand der Faltschachtel überdecken.An advantageous development of the invention is that a front wall flap and two side wall flaps are articulated on the top wall, which cover the front wall and the two side walls in the erected state of the folding box.

Damit ist auch ein verhältnismäßig dichter oberer Abschluß der aufgerichteten Faltschachtel gewährleistet. Diese Klappen können an den überdeckten Wänden noch zusätzlich angeklebt werden, wodurch sich eine noch bessere Abdichtung ergibt.This also ensures a relatively tight upper closure of the erected folding box. These flaps can also be glued to the covered walls, which results in an even better seal.

Dabei ist es dann besonders günstig, wenn erfindungsgemäß wenigstens die eine der beiden Seitenwandklappen mit einer Aufreißperforation versehen ist.It is then particularly advantageous if, according to the invention, at least one of the two side wall flaps is provided with a tear-open perforation.

Ein besonders einfaches Öffnen der aus dem Kartonzuschnitt aufgerichteten Faltschachtel ist dann gewährleistet, wenn erfindungsgemäß als Aufreißperforation zwei parallel zueinander verlaufende Perforationslinien vorgesehen sind, zwischen denen ein aus der Seitenwandklappe heraustrennbarer Streifen vorgesehen ist.A particularly simple opening of the folding box erected from the cardboard blank is ensured if, according to the invention, two perforation lines running parallel to one another are provided as the tear perforation, between which a strip that can be separated from the side wall flap is provided.

Ein solcher Aufreiß-Streifen läßt sich leicht erfassen und aus der Seitenwandklappe heraustrennen.Such a tear strip can be easily grasped and separated from the side wall flap.

In der Zeichnung ist die Erfindung anhand eines Ausführungsbeispiels veranschaulicht. Dabei zeigen:

Fig.2
eine aus dem Kartonzuschnitt nach Fig.1 aufgerichtete Faltschachtel.
The invention is illustrated in the drawing using an exemplary embodiment. Show:
Fig. 1
a flat cardboard blank to make a folding box and
Fig. 2
a folding box erected from the cardboard blank according to Fig. 1.

Mit 1 ist in Fig.1 ein Kartonzuschnitt bezeichnet, der einen Boden 2 aufweist, an welchem über eine Faltlinie 3 eine Vorderwand 4 angelenkt ist. Über zwei weitere Faltlinien 5 und 6 sind mit dem Boden 2 zwei Seitenwände 7 bzw. 8 verbunden, während der Vorwand gegenüberliegend über eine Faltlinie 9 eine Rückwand 10 am Boden angelenkt ist. Die Faltlinien 3, 5, 6 und 9 sind auch gleichzeitig die seitlichen Begrenzungslinien dieser vier Wände 4, 7, 8 und 10 und dienen darüber hinaus der Anlenkung von vier Zwischenflächen 11, 12, 13 und 14 die zwischen den benachbarten Wänden angeordnet und jeweils durch eine Faltlinie 15 in zwei Abschnitte unterteilt sind. Die durch die beiden Begrenzungskanten und die Faltlinie 15 gebildete Spitze 40 der Zwischenflächen 11, 12, 13 und 14 fluchtet annähernd mit der Begrenzungskante der angrenzenden Seitenwand 7 bzw. 8. Darüber hinaus ist jede der Zwischenflächen mit einem spitzwinkligen Ausschnitt versehen, dessen Spitze bei der Spitze 40 beginnt und dessen der Spitze gegenüberliegende Breitseite an die jeweilige Seitenwand 7 bzw. 8 angrenzt.1 in FIG. 1 denotes a cardboard blank that has a bottom 2, to which a front wall 4 is articulated via a folding line 3. Two side walls 7 and 8 are connected to the bottom 2 via two further folding lines 5 and 6, while a back wall 10 is articulated on the bottom opposite the front wall via a folding line 9. The fold lines 3, 5, 6 and 9 are also the lateral boundary lines of these four walls 4, 7, 8 and 10 and also serve to link four intermediate surfaces 11, 12, 13 and 14 which are arranged between the adjacent walls and each through a fold line 15 is divided into two sections. The tip 40 of the intermediate surfaces 11, 12, 13 and 14 formed by the two boundary edges and the fold line 15 is approximately aligned with the boundary edge of the adjacent side wall 7 and 8. In addition, each of the intermediate surfaces is provided with an acute-angled cut-out, the tip of which at Tip 40 begins and the broad side opposite the tip adjoins the respective side wall 7 or 8.

Durch diese Ausgestaltung liegt beim Auffalten des Unterteils im oberen Eckbereich keine Verdopplung des Zwickelflächenmaterials vor und trotzdem liegt die Spitze 40 mit ihrer siegelfähigen Innenseite an dem oberen Rand der Seitenwand 7,8 an und kann mit diesem versiegelt werden.As a result of this configuration, when the lower part is unfolded in the upper corner region, there is no doubling of the gusset surface material and nevertheless the tip 40 lies with its sealable inside against the upper edge of the side wall 7, 8 and can be sealed with it.

An der Rüchwand 10 ist über eine parallel zur Faltlinie 9 verlaufende weitere Faltlinie 16 eine Deckwand 17 angelenkt, die ihrerseits über eine Faltlinie 18 eine Vorderwandklappe 19 trägt. Die beiden anderen Kanten der Deckwand 17 tragen über je eine Faltlinie 25,26 Seitenwandklappen 27,28, wobei die Faltlinien 25 und 26 gegenüber den Faltlinien 5 und 6 geringfügig nach außen versetzt angeordnet sind, wodurch die Deckwand 17 etwas breiter als der Boden 2 ist. Die Seitenwandklappe 27 weist zwei parallel zueinander verlaufende Perforationslinien 29 und 30 auf, zwischen denen ein Aufreißstreifen 31 liegt, dessen eines Ende 32 geringfügig über die Seitenwandklappe vorsteht und damit gut greifbar ist.A top wall 17 is articulated on the rear wall 10 via a further folding line 16 running parallel to the folding line 9, which in turn carries a front wall flap 19 via a folding line 18. The two other edges of the top wall 17 each carry a folding line 25, 26 side wall flaps 27, 28, the folding lines 25 and 26 being arranged slightly offset outwards from the folding lines 5 and 6, as a result of which the top wall 17 is somewhat wider than the bottom 2 . The side wall flap 27 has two perforation lines 29 and 30 running parallel to one another, between which there is a tear strip 31, one end 32 of which protrudes slightly beyond the side wall flap and is therefore easy to grasp.
