Description

Die vorliegende Erfindung betrifft einen Zuschnitt für eine Faltschachtel gemäß dem Gattungsbegriff des unabhängigen Patentanspruchs 1.The present invention relates to a blank for a folding box according to the preamble of independent claim 1.

Faltschachteln, bei denen Seitenränder mit Zungen versehen sind, die nach Hindurchstekken durch Schlitze die Wände in der Gebrauchslage halten, werden Steck-Faltschachteln genannt. Sie haben den Vorteil, daß sie in einem Verkaufsgeschäft in einer Ebene ausgebreitet aufbewahrt werden können und zum Gebrauch zusammengesteckt werden können und deshalb sowohl zum Transport als Rohmaterial als auch bei der Lagerung wenig Raum beanspruchen.Folding boxes in which the side edges are provided with tongues that hold the walls in the position of use after being pushed through slots are called plug-in folding boxes. They have the advantage that they can be kept spread out on one level in a retail store and can be put together for use and therefore require little space both for transport as raw material and for storage.

Eine erste solche Faltschachtel ist beispielsweise in der CH-A-267 021 beschrieben. Hier weisen gegenüberliegende Seitenwände Lappen auf, die zum Einstecken in Schlitze in benachbarten Stirnwänden eingerichtet sind. Zur sicheren Halterung in den Schlitzen weisen die Enden der Zungen eine Verbreiterung auf. Auch die Deckwand kann nach Umfalten auf die Schachtel mittels Zungen in Schlitzen von Stirnwänden in Schließlage befestigt werden.A first such folding box is described, for example, in CH-A-267 021. Here, opposite side walls have tabs which are set up for insertion into slots in adjacent end walls. The ends of the tongues have a broadening for secure mounting in the slots. The top wall can also be fastened in the closed position by means of tongues in the slots in the end walls after folding over onto the box.

Wenn auch eine solche Schachtel für das Einpacken von Patisserie oder dgl. gut geeignet ist, weist sie nach heutiger Ansicht mehrere Nachteile auf: Damit an den Kanten ein einwandfreier Verschluß gewährleistet ist, müssen die Zungen am Ende von Verschlußlaschen angebracht sein, was zu erhöhtem Materialaufwand führt, was die Zuschnitte verteuert. Eine spätere Entnahme des eingepackten Materials ist schwierig, weil die Verbreiterung der Zungen dem Öffnen einen Widerstand entgegensetzt und schließlich liegen bekanntlich die Laschen mit den Zungen außenseitig der Schachtel, was das Anbringen von Verzierungen oder Reklamedrucken erschwert.Even if such a box is well suited for packing patisserie or the like, it has several disadvantages from today's perspective: In order to ensure a perfect closure at the edges, the tongues must be attached to the end of the closure flaps, which increases the cost of materials leads what makes the cuts more expensive. A later removal of the packed material is difficult because the widening of the tongues opposes the opening and finally the tabs with the tongues are known to lie on the outside of the box, which makes it difficult to apply decorations or advertising prints.

Der zuletzt genannte Nachteil wurde gemäß der CH-A-520 032 behoben, indem die Schlitze in der Faltlinie zwischen Laschen und Seitenwänden angeordnet wurden, so daß bei der zusammengesteckten Faltschachtel die Laschen und die Zungen im Innern der Schachtel angeordnet waren. Aber sowohl das Zusammenstellen der Schachtel als auch das Öffnen ist nicht für Ware bestimmt, die sich leicht verformen läßt und überdies wird bei jeder Kante ein erheblicher Anteil von Material ausgestanzt.The last-mentioned disadvantage was remedied in accordance with CH-A-520 032 by arranging the slots in the fold line between flaps and side walls, so that the flaps and tongues were arranged inside the box when the folding box was assembled. But both the assembly of the box and the opening are not intended for goods that can be easily deformed and, moreover, a considerable amount of material is punched out at each edge.

Eine weitere vergleichbare Schachtel ist aus der GB-A-893 469 bekannt.Another comparable box is known from GB-A-893 469.

Es ist deshalb eine Aufgabe der Erfindung, eine Faltschachtel zu schaffen, bei der mit minimalstem Materialaufwand und ohne Zungen und Schlitze eine Schachtel zusammengestellt werden kann, die einen Verschluß bei allen Kanten zwischen den Seitenwänden aufweist und die sich mit wenigen Handgriffen vollständig aufklappen läßt, so daß sich auch sehr leicht verformbare Gegenstände wie Rahm-Torten oder dgl. ohne Beschädigung entnehmen lassen.It is therefore an object of the invention to provide a folding box in which a box can be put together with a minimal amount of material and without tongues and slots, which has a closure at all edges between the side walls and which can be opened completely in a few steps, so that easily deformable objects such as cream cakes or the like can be removed without damage.

Erfindungsgemäß läßt sich diese Aufgabe durch die Merkmale im kennzeichnenden Teil des unabhängigen Patentanspruchs 1 erfüllen.According to the invention, this object can be achieved by the features in the characterizing part of independent patent claim 1.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung erläutert. Es zeigt

  • Fig. 1 eine Draufsicht auf den Zuschnitt nach der Erfindung und
  • Fig. 2 eine perspektivische Ansicht einer zum Teil gefalteten und in einer Phase beim Schließvorgang dargestellten Steck-Faltschachtel.
An embodiment of the invention is explained below with reference to the drawing. It shows
  • Fig. 1 is a plan view of the blank according to the invention and
  • Fig. 2 is a perspective view of a partially folded and shown in a phase during the closing folding box.

Der Zuschnitt gemäß Fig. 1 zeigt eine Bodenwand 1, eine Deckwand 2, einen Rückwandstreifen 3, eine Vorderwand 4 und vier Seitenwandstreifen 5, 6, 7 und 8. Eine Verschlußlasche ist als überdeckende Vorderwand 9 ausgebildet. Die Bodenwand 1 und die Deckwand 2 sind vom Rückwandstreifen 3 durch Faltlinien 10, 11 abgegrenzt, und die Vorderwand 4 ist von der Deckwand 2 durch eine Faltlinie 12 abgegrenzt. Die Seitenwandstreifen bilden je eine durchgehende Randkante 20, 21 und weisen Verlängerungen 30, 31 an den Seitenwandstreifen 6, 8 und 32, 33 an den Seitenwandstreifen 5, 6 auf. Diese Verlängerungen 30-33 sind von den benachbarten Seitenwandstreifen durch Faltlinien 13, 14, 15, 16 abgegrenzt. Die überdeckende Vorderwand 9 ist von der Bodenwand 1 durch eine Faltlinie 17 abgegrenzt. Diese Faltlinie 17 und die Faltlinien 14, 16 in den Seitenwandstreifen 7,8 liegen auf einer Geraden. Ebenso wie auch die Faltlinien 12 und die Faltlinien 13, 15 auf einer Geraden liegen.1 shows a bottom wall 1, a top wall 2, a rear wall strip 3, a front wall 4 and four side wall strips 5, 6, 7 and 8. A closure flap is designed as a covering front wall 9. The bottom wall 1 and the top wall 2 are delimited from the rear wall strip 3 by fold lines 10, 11, and the front wall 4 is delimited from the top wall 2 by a fold line 12. The side wall strips each form a continuous edge 20, 21 and have extensions 30, 31 on the side wall strips 6, 8 and 32, 33 on the side wall strips 5, 6. These extensions 30-33 are delimited from the adjacent side wall strips by fold lines 13, 14, 15, 16. The overlapping front wall 9 is delimited from the bottom wall 1 by a fold line 17. This fold line 17 and the fold lines 14, 16 in the side wall strips 7, 8 lie on a straight line. Just as the fold lines 12 and the fold lines 13, 15 lie on a straight line.

Die Verlängerungen 30, 32 sind durch Einschnitte 34,35 von der Vorderwand 4 abgetrennt, und zwischen den Verlängerungen 31,33 und der überdeckenden Vorderwand 9 sind ebenfalls trennende Einschnitte 36, 37 vorhanden.The extensions 30, 32 are separated by cuts 34, 35 from the front wall 4, and between the extensions 31, 33 and the overlapping front wall 9 there are also separating cuts 36, 37.

Die Seitenwandstreifen 5, 6 bzw. 7, 8 sind durch Seitenfaltlinien 42, 43 bzw. 44, 45 von der Deckwand 2 bzw. der Bodenwand 1 abgegrenzt. Durch die über die Seitenwandstreifen hinaus verlängerten Faltlinien 10, 11 zur Abgrenzung des Rückwandstreifens 3 von Boden- und Deckwand 1, 2 werden Seitenmittelpartien 40, 41 gebildet. Diese Seitenmittelpartien 40, 41 weisen ausgeschnittene Dreiecke 46, 47 auf, und zwar liegen die Dreieckseiten einerseits auf den Seitenfaltlinienabschnitten 48, 49 und auf den Diagonalen 50, 51, bzw. 52, 53. Auf den äußeren Hälften dieder Diagonalen 50-53 sind Faltlinien in Form von das Material durchdringenden unterbrochenen Einschnitten gebildet.The side wall strips 5, 6 and 7, 8 are delimited from the top wall 2 and the bottom wall 1 by side fold lines 42, 43 and 44, 45. The middle lines 40, 41 are formed by the fold lines 10, 11 which extend beyond the side wall strips to delimit the rear wall strip 3 from the bottom and top walls 1, 2. These side middle parts 40, 41 have cut out triangles 46, 47, namely the triangular sides lie on the one hand on the side fold line sections 48, 49 and on the diagonals 50, 51 and 52, 53. Fold lines are on the outer halves of the diagonals 50-53 in the form of interrupted cuts penetrating the material.

Schließlich weist noch die überdeckende Vorderwand 9 eine Einsteckzunge 60 mit einer Zugzunge 61 auf und entsprechend ist an der Vorderwand 4 bei der Faltlinie 12 ein Einschnitt 62 vorhanden, um damit die Schachtel im gefalteten Zustand zusammenzuhalten und die Verlängerungen 31, 33 sind mit Einhakeinschnitten 63, 64 versehen.Finally, the overlapping front wall 9 also has an insertion tongue 60 with a pull tongue 61, and accordingly an incision 62 is present on the front wall 4 at the folding line 12 in order to hold the box together in the folded state and the extensions 31, 33 are provided with hooking incisions 63, 64 provided.

Die Faltung dieses Zuschnittes ist aus Fig.2 2 ersichtlich. Zuerst werden die Seitenwandstreifen 7, 8 nach oben gebogen und die Verlängerungen 31, 33 um die Faltlinien 14,16 umgebogen und durch Einhaken der Einhakeinschnitte 63, 64 untereinander befestigt. Durch Aufklappen der Seitenwandstreifen 5 und 6 an der Deckwand 2 durch Falten entlang der Faltlinien 42, 43 und Hochschwenken der Deckwand 2 um die Faltlinie 10 werden, wenn die Seitenwandstreifen 7 und 8 nach innen gedrückt werden, die Seitenmittelpartien 40, 41 gefalzt, und zwar bilden sich zuerst Faltkanten entlang den Diagonalen 50, 52 und der Faltlinie 11, die gegensinnig angeordnet sind, wobei die Faltung über die gesamte Faltlinie 11 gleichbleibend ist. In der letzten Schließphase ergeben sich dann noch die Faltkanten entlang den Diagonalen 51 und 53.The folding of this blank can be seen in Fig.2 2. First, the side wall strips 7, 8 are bent upwards and the extensions 31, 33 are bent over the fold lines 14, 16 and by hooking the hook incisions 63, 64 attached to each other. By unfolding the side wall strips 5 and 6 on the top wall 2 by folding along the fold lines 42, 43 and swinging up the top wall 2 around the fold line 10, when the side wall strips 7 and 8 are pressed inwards, the side middle parts 40, 41 are folded, namely first fold edges are formed along the diagonals 50, 52 and the fold line 11, which are arranged in opposite directions, the fold over the entire fold line 11 being constant. In the last closing phase, the folded edges along the diagonals 51 and 53 result.

Wenn die Deckwand schließlich auf den Seitenwandstreifenkanten 20, 21 aufliegt, können die Verlängerungen 30, 32 eingeklappt und die Vorderwand 4 nach unten geklappt werden. Die überdeckende Vorderwand 9 wird noch hochgeklappt und die Zunge 60 in den Schlitz 62 hineingestoßen, wodurch die Schachtel in ihrem geschlossenen Zustand bleibt.When the top wall finally rests on the side wall strip edges 20, 21, the extensions 30, 32 can be folded in and the front wall 4 can be folded down. The overlapping front wall 9 is still folded up and the tongue 60 is pushed into the slot 62, whereby the box remains in its closed state.

Beim Öffnen der Schachtel wird zuerst die Zunge 60 aus dem Schlitz 62 durch Ziehen an der Zuglasche 61 herausgezogen und dann die Deckwand nach hinten geklappt. Nach dem Aushaken der beiden Verlängerungen 31, 33 können die Seitenwandstreifen ebenfalls nach unten geklappt werden, und der Schachtelinhalt liegt frei und kann nach der Seite oder nach vorn herausgezogen oder geschoben werden. Er braucht damit nicht in die Höhe gehoben zu werden.When opening the box, the tongue 60 is first pulled out of the slot 62 by pulling on the pull tab 61 and then the top wall is folded back. After unhooking the two extensions 31, 33, the side wall strips can also be folded down, and the contents of the box are exposed and can be pulled out or pushed to the side or to the front. It does not need to be lifted up.

Eine solche Schachtel braucht damit keine Zungen und Einschnitte an jeder Kante zwischen den Seitenwänden, um eine gute Halterung zu bilden. Wie überdies aus Fig. 2 deutlich erkennbar ist, ergibt sich durch die Seitenmittelpartien in der vorgeschlagenen Ausführungsform ein vollständiger Verschluß der Schachtel, weil die äußeren Diagonalenhälften der Diagonalen 51, 53 sich auf deren innere Diagonalenhälften falten, so daß die Dreiecke 65, 66 auf die ausgeschnittenen Dreiecke 46, 47 zu liegen kommen und damit diese Öffnungen zudecken.Such a box therefore does not need tongues and cuts on each edge between the side walls in order to form a good holder. As can also be clearly seen from FIG. 2, the side middle parts in the proposed embodiment result in a complete closure of the box because the outer diagonal halves of the diagonals 51, 53 fold onto their inner diagonal halves, so that the triangles 65, 66 on the cut triangles 46, 47 come to rest and thus cover these openings.

Außer diesen zwei genannten Vorteilen wird ein heute sehr wesentlicher Vorteil darin gesehen, daß an den Kanten zwischen den Seitenwänden keine zusätzlichen Laschen und Zungen anzuordnen sind und daß daher ein wesentlicher Teil an Material eingespart werden kann, das sonst durch die notwendigerweise ausgeschnittenen Ecken als verloren zu gelten hat.In addition to these two advantages mentioned, a very important advantage is seen today in the fact that no additional tabs and tongues are to be arranged on the edges between the side walls and that therefore a substantial amount of material can be saved which would otherwise be lost as a result of the corners cut out necessarily has to apply.

Anstelle der in diesem Ausführungsbeispiel beschriebenen Form mit ausgestanzten und entfernten Dreiecken 46, 47 können nur die in den Diagonalen 50, 53 liegenden Dreieckseiten gestanzt sein, während die Basislinie als Faltlinie geprägt ist. Damit können die Dreiecke innenseitig in die Faltschachtel eingelegt werden und dienen dann als Dichtung bei rieselfähigem Gut. Wenn die Dreiecke 46, 47 nach außen geklappt und mit den Seitenwänden 5, 6 verklebt werden, ergeben sich eine Verstärkung des Rückwandstreifens 3 bzw. des Bodens der geschlossenen Faltschachtel.Instead of the shape described in this exemplary embodiment with punched and removed triangles 46, 47, only the triangular sides lying in the diagonals 50, 53 can be punched, while the base line is embossed as a fold line. This means that the triangles can be inserted on the inside into the folding box and then serve as a seal for free-flowing goods. If the triangles 46, 47 are folded outwards and glued to the side walls 5, 6, there is a reinforcement of the rear wall strip 3 or the bottom of the closed folding box.
