Abstract

Inner and outer closure flaps (16,17) hinged to opposing sidewalls (6,8) both extend right along the interposed sidewall (7) and the sidewalls (5) between the sidewalls have hinged dust flaps (18,19). These flaps are in turn slotted out at the sides (22,23) and are here engaged by the side edges of the inner closure flap. The side edges of the specified flap are themselves slotted out (20,21) to be engaged by the dust flaps. The inside flap at least is indented to at least the material thickness and shaped to correspond to the dust flaps.

Description

Die Erfindung bezieht sich auf eine Faltschachtel aus Karton oder dergleichen, mit einem hülsenförmigen Mantel, mit vier Seitenwänden, die über Faltlinien aneinander angelenkt und über eine Längsklebenaht miteinander verbunden sind, wobei an den Seitenwänden einerseits Bodenklappen und andererseits Deckelklappen angeordnet sind.The invention relates to a folding box made of cardboard or the like a sleeve-shaped sheath, with four side walls, which fold over each other are articulated and connected to one another via a longitudinal adhesive seam, with the Side walls on the one hand bottom flaps and on the other hand lid flaps arranged are.

Faltschachteln werden nach dem Befüllen an ihrer Deckel- oder ihrer Bodenseite durch Kleben verschlossen. Dabei ist es insbesondere beim Verpacken von Lebensmitteln wichtig, daß die Faltschachtel auch gegen das Eindringen von Insekten und dergleichen einigermaßen dicht ist. Die Schwachstelle dabei ist der Endverschluß, da ein Versiegeln nicht in Frage kommt.Folding boxes are filled through on their lid or bottom side Glue closed. It is especially when packaging food it is important that the folding box also protects against the penetration of insects and the like is reasonably dense. The weak point here is the end closure, there sealing is out of the question.

Der Erfindung liegt die Aufgabe zugrunde, eine Faltschachtel der genannten Art so auszugestalten, daß auch bei der nach dem Befüllen zu verschließenden Verschlußstelle eine große Dichtigkeit gegeben ist. The invention has for its object a folding box of the type mentioned to design that also with the to be closed after filling Closure point is a great seal.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an zwei im aufgerichteten Zustand der Faltschachtel einander gegenüberliegenden Seitenwänden je eine innenliegende und eine außenliegende Verschluß-Klappe angelenkt ist, die sich beide über die ganze Lange der dazwischen liegenden Seitenwand erstrecken.This object is achieved in that erected on two Condition of the folding box opposite side walls one each inside and an outside closure flap is articulated, both of which extend the entire length of the side wall between them.

Dadurch überlappen die beiden Verschlußklappen über den ganzen Querschnitt der Faltschachtel und ergeben sehr lange Eintrittswege, die nur sehr schwer zu überwinden sind.As a result, the two flaps overlap over the entire cross section of the Folding box and result in very long entry routes that are very difficult to overcome are.

Eine weitere vorteilhafte Ausgestaltung der Erfindung liegt darin, daß an den beiden zwischen den die Verschluß-Klappen tragenden Seitenwänden liegenden anderen Seitenwänden Staubklappen angelenkt sind, die mit seitlichen Aussparungen versehen sind, in welche die innenliegende Verschluß-Klappe mit ihren Seitenkanten einzugreifen vermag.Another advantageous embodiment of the invention is that on the two between the other side walls carrying the flaps Dust flaps are hinged on the side walls and provided with side recesses are, in which the inner closure flap with its side edges is able to intervene.

Damit kann sich die innenliegende Verschluß-Klape an den Staubklappen abstützen und weicht beim Verkleben mit der außenliegenden Verschlußklappe nicht unkontrolliert aus.This allows the internal clasp to be supported on the dust flaps and does not give way when glued to the external flap out of control.

Sehr vorteilhaft ist auch eine weitere Ausgestaltung der Erfindung, bei der die Seitenkanten der innen liegenden Verschluß-Klappe mit Aussparungen versehen sind, in welche die Staubklappen einzugreifen vermögen.A further embodiment of the invention in which the Side edges of the internal flap are provided with recesses, in which the dust flaps can intervene.

Damit können auch die Staubklappen eine günstige Breite erhalten wodurch auch hier eine vorteilhafte Abdichtung erzielt wird.This means that the dust flaps can also have a favorable width, which means that here too an advantageous seal is achieved.

Sehr vorteilhaft ist es auch, wenn gemäß einer weiteren Ausgestaltung der Erfindung die innenliegende Verschluß-Klappe mit Einprägungen versehen ist, deren Tiefe wenigstens annähernd der Materialstärke entsprechen und deren Form der Form der Staubklappen angepasst ist. It is also very advantageous if, according to a further embodiment of the invention the internal flap is stamped, the depth correspond at least approximately to the material thickness and their shape to the shape of the Dust flaps is adjusted.

Dadurch wird als Auflagefläche für die äußere Verschluß-Klappe eine weitgehend ebene Fläche zur Verfügung gestellt.As a result, a largely as a bearing surface for the outer closure flap provided a flat surface.

Jenachdem von welcher Seite her die Faltschachtel befüllt wird, liegen die Verschluß-Klappen entweder an der Deckel- oder an der Bodenseite.Depending on the side from which the folding box is filled, the closure flaps are located either on the lid or on the bottom side.

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

Fig.1
einen flach liegenden Kartonzuschnitt mit Seitenwänden und daran angelenkten Verschlußklappen und
Fig.2
eine schaubildliche Darstellung des oberen Teils einer aus dem Kartonzuschnitt nach Fig.1 aufgerichteten Faltschachtel.
The invention is illustrated in the drawing using an exemplary embodiment. Show:
Fig. 1
a flat cardboard blank with side walls and hinged flaps and
Fig. 2
a schematic representation of the upper part of a folding box erected from the cardboard blank according to Fig.1.

Mit 1 ist in Fig.1 ein flachliegender Kartonzuschnitt bezeichnet, der vier über Faltlinien 2, 3 und 4 miteinander verbundene Seitenwände 5,6,7,8 aufweist, die alle etwa die gleiche Breite haben, wodurch beim Aufrichten eine im Querschnitt etwa quadratische Faltschachtel entsteht. Über eine weitere Faltlinie 9 ist an der freien Seitenwand 8 eine Klebelaschen 10 angelenkt, welche mit der am anderen Ende angelenkten Seitenwand 5 in einer Klebenaht verbunden wird. Am unteren Ende der beiden Seitenwände 6 und 8 sind über eine Faltlinie 11 Verschlußklappen 12 und 13 angelenkt, welche in ihrer Länge etwa der Breite der beiden anderen Seitenwände 5 und 7 entsprechen. Diese beiden Seitenwände 5 und 7 sind über die gleiche Faltlinie 11 mit Staubklappen 14 und 15 versehen.1 in Fig.1 is a flat cardboard blank, the four over Fold lines 2, 3 and 4 interconnected side walls 5,6,7,8, all of them have approximately the same width, which means that a cross-section approximately when erecting square folding box is created. Another fold line 9 is on the free Sidewall 8 hinged an adhesive tab 10, which with the other end articulated side wall 5 is connected in an adhesive seam. At the bottom of the Both side walls 6 and 8 are 11 flaps 12 and 13 via a fold line articulated, which in its length is approximately the width of the other two side walls 5 and 7 correspond. These two side walls 5 and 7 are over the same fold line 11 provided with dust flaps 14 and 15.

Am anderen Ende der Seitenwände 5 bis 8 sind weitere Verschlußklappen 16 und 17 sowie Staubklappen 18 und 19 vorgesehen. At the other end of the side walls 5 to 8 there are further flaps 16 and 17 and dust flaps 18 and 19 provided.

Nach dem Verbinden der Klebelasche 10 mit der Seitenwand 5 werden die Seitenwände zu einer quadratischen Hülse aufgerichtet. Daraufhin wird die Verschlußklappe 12 um 90° nach innen umgefaltet und die beiden Staubklappen 14 und 15 daraufgefaltet. Als letztes wird noch die Verschlußklappe 13 auf die Aussenseite aufgefaltet und das Ganze mittels eines nicht dargestellten Innenstempels und eines äusseren Anpresswerkzeuges unter Wärmeeinwirkung zusammengeklebt.After connecting the adhesive tab 10 to the side wall 5, the Sidewalls erected into a square sleeve. Then the Folding flap 12 folded inwards by 90 ° and the two dust flaps 14 and 15 folded on it. Finally, the shutter 13 on the Unfolded outside and the whole thing with an inner stamp, not shown and an outer pressing tool glued together under the influence of heat.

Hierauf kann die Verpackung gefüllt und danach auch an ihrem anderen Ende verschlossen werden.The packaging can then be filled and then at its other end be closed.

Da hierbei kein Innenstempel eingesetzt werden kann, würde die innere Verschlußklappe 16 beim Verbinden mit der äusseren Verschlußklappe 17 ausweichen und es würde keine vollflächige Verbindung zustande kommen.Since no inner stamp can be used here, the inner one Dodge the flap 16 when connecting to the outer flap 17 and there would be no full-surface connection.

Die innere Verschlußklappe 16 ist daher seitlich mit Ausnehmungen 20 und 21 versehen, in welche die Staubklappen 18 und 19 einfassen, wobei das freie Ende der Verschlußklappe 16 auf den beiden Staubklappen aufliegt und dadurch abgestützt wird. Der übrige Abschnitt der beiden Staubklappen liegt dagegen auf der Verschlußklappe 16 auf. Die beiden Staubklappen können dabei ebenfalls mit Ausnehmungen 22 und 23 versehen sein, in welchen sich die Verschlußklappe abstützt und so eine größere Breite der Staubklappen zulässt.The inner flap 16 is therefore laterally with recesses 20 and 21st provided, in which the dust flaps 18 and 19 border, the free end of the Closure flap 16 rests on the two dust flaps and is thereby supported becomes. The remaining section of the two dust flaps, however, lies on the Flap 16 on. The two dust flaps can also be used Recesses 22 and 23 may be provided, in which the closure flap is supported and so allows a larger width of the dust flaps.

Als Abschluß wird die Verschlußklappe 17 aussen aufgefaltet und mit den darunterliegenden Klappen möglichst vollflächig verklebt.Finally, the flap 17 is unfolded on the outside and with the the flaps underneath are glued as far as possible.

Um die unterschiedlichen Materialanhäufungen beim Aufeinanderlegen der Verschlußklappen und der Staubklappen auszugleichen, kann die innere Verschlußklappe 16 und eventuell auch die beiden Staubklappen 18 und 19 mit Prägungen versehen sein, so daß beim Aufeinanderlegen eine weitgehend ebene Flache erzielt wird.To the different material accumulations when stacking the The flaps and the dust flaps can compensate for the inner Flap 16 and possibly also the two dust flaps 18 and 19 with Be embossed so that when placed on top of each other a largely flat surface is achieved.
