Description

Die Erfindung bezieht sich auf eine Faltschachtel mit zwischen zwei einander benachbarten, einschwenkbaren Decklaschen angeordneten Seitenlaschen mit seitlichen Faltecken, wobei die Faltecken über beide Decklaschen einfaltbar sind.The invention relates to a folding box with side flaps with side folding corners arranged between two adjacent, pivotable top flaps, the folding corners being foldable over both top flaps.

Bei einer bekannten Schachtel (GB-PS 1 202 565) werden die Faltecken unter die beiden Decklaschen auf die Seitenlaschen eingeschlagen. Dadurch läßt sich die schmale Seite der Faltschachtel nicht abdichten, weil längs des Randes der Faltecke bei aufgeklebter oberer Decklasche ein Zwischenraum entsteht, durch den Staub ein- oder ausdringen kann.In a known box (GB-PS 1 202 565), the folding corners are turned under the two cover flaps on the side flaps. As a result, the narrow side of the folding box cannot be sealed, because a gap is created along the edge of the folding corner when the upper cover flap is glued on, through which dust can penetrate or escape.

Bei Faltschachteln nach der US-PS 3 120 334 sind nur jeweils zwei statt vier Faltecken pro Grund- bzw. Deckfläche vorhanden.In folding boxes according to US Pat. No. 3,120,334, there are only two instead of four folding corners per base or top surface.

An den Ecken, an denen die Faltecken fehlen, kann daher kein staubdichter Verschluß garantiert werden.At the corners where the folding corners are missing, a dustproof closure cannot be guaranteed.

Die Faltschachtel nach der GB-PS 2 017 641 weist zwar eine Faltecke an jeder Ecke der Faltschachtel auf. In diesem Falle sind jedoch die Faltecken zwar über die untere Decklasche, aber immer noch unter die obere Decklasche eingeschlagen, so daß die Undichtheit längs des Randes dieser Faltecke nicht behoben ist. Die obere Decklasche kann nicht so abgebogen werden, daß die Unterseite der Decklasche immer dicht an den Stirnflächen der Ränder der Faltecken anliegt. Auch bei großen Faltecken ist eine Staubdichtigkeit nicht gegeben. Die bekannten Faltschachteln eignen sich daher nicht zur Aufbewahrung und Versendung von staubförmigen Medien, beispielsweise losem Pulver. Dieses muß vielmehr in staubdicht verschlossenen Beuteln in diese Schachteln eingebracht werden, damit es in der Schachtel transportiert werden kann. Bei diesen bekannten Faltschachteln kann aber auch in der Umgebung vorhandener Staub durch die Ritzen des Verschlusses hindurch in das Innere der Faltschachtel gelangen.The folding box according to GB-PS 2 017 641 has a folding corner at every corner of the folding box. In this case, however, the fold corners are turned over the lower cover flap, but still under the upper cover flap, so that the leakage along the edge of this fold corner is not eliminated. The upper cover flap cannot be bent so that the underside of the cover flap always lies close to the end faces of the edges of the folding corners. Dust-tightness is not guaranteed even with large folding corners. The known folding boxes are therefore not suitable for storing and sending dusty media, for example loose powder. Rather, this must be introduced into these boxes in dust-tightly sealed bags so that it can be transported in the box. In the case of these known folding boxes, however, dust present in the surroundings can also get into the interior of the folding box through the cracks in the closure.

Eine Faltschachtel der eingangs genannten Art ist mit der FR-A 1 028 741 bekannt geworden. Diese Faltschachtel weist zwar seitliche einfaltbare Faltecken auf, jedoch bieten diese Faltecken durch das ausschließliche Einfalten keine Gewähr für eine staubdichte Verpackung. Außerdem tragen die Seitenlaschen durch die hohen Faltecken bei eingefaltetem Verschluß sehr auf.A folding box of the type mentioned is known from FR-A 1 028 741. Although this folding box has folding corners that can be folded in at the side, these folding corners, due to the fact that they are folded in, do not guarantee dust-tight packaging. In addition, the side flaps are very bulky due to the high folding corners when the closure is folded.

Der Erfinder hat sich die Aufgabe gestellt, eine Faltschachtel zu entwickeln, die einen staubdichten Verschluß aufweist.The inventor has set himself the task of developing a folding box that has a dustproof seal.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß auf den den Decklaschen benachbarten Seitenlaschen Leim in Form eines Streifens auf der Innenseite und in der Nähe ihrer Biegelinie aufgetragen ist und daß dieser Leimstreifen auch die Außenseite der eingefalteten Faltecken bedeckt. Dadurch wird erreicht, daß die sonst schwer abzudichtende Ecke der Faltschachtel dicht wird und die Lasche und die Faltecke beim Aufkleben auf der darunterliegenden, quer zu ihr eingeklappten Lasche fest haftet. Unter Leimstreifen ist dabei auch ein heißlaufestschweißender Materialstreifen zu verstehen.This object is achieved according to the invention in that glue is applied in the form of a strip on the inside and in the vicinity of its bending line on the side plates adjacent to the cover plates, and in that this strip of glue also covers the outside of the folded folding corners. This ensures that the otherwise difficult-to-seal corner of the folding box becomes tight and the flap and the folding corner firmly adheres to the underlying flap which is folded in transversely to it. A glue strip is also to be understood as a strip of material that welds against hot running.

Bei einer Ausführungsform der Erfindung weist mindestens eine Decklasche an ihrem seitlichen Rand an ihren oberen, freien Rand anschließend einen Rücksprung (Versatz) auf. In dem freien Raum, der durch die Zurücksetzung des Randes an dieser Stelle erzielt worden ist, kann sich die untere Decklasche eng an die Anlenkung der Seitenlasche anschmiegen. Befindet sich der Rücksprung an der oberen Decklasche, so erleichtert dieser Rücksprung das Einfalten der oberen Decklasche bei eingefalteter Faltecke. Dieser Rücksprung kann, insbesondere an der oberen Decklasche bei Ausführungsformen der Erfindung auch an die Biegelinie der Decklasche anschließend vorgesehen sein, über die die Decklasche mit der Seitenwand der Schachtel verbunden ist.In one embodiment of the invention, at least one cover flap has a recess (offset) on its lateral edge on its upper, free edge. In the free space that has been achieved by resetting the edge at this point, the lower cover flap can nestle closely against the linkage of the side flap. If the recess is on the upper cover flap, this recess makes it easier to fold in the upper cover flap when the folding corner is folded in. This recess can be provided, in particular on the upper cover flap in embodiments of the invention, also after the bending line of the cover flap via which the cover flap is connected to the side wall of the box.

Bei einer Ausführungsform der Erfindung weist die Faltecke die Form eines gleichschenkligen, rechtwinkligen Dreiecks auf, an dessen langer Seite die Biegelinie geritzt ist. Dies hat den Vorteil, daß die Faltecke nach dem Faltvorgang flach und ohne Wulstbildung an der Seitenlasche anliegt. Das Ritzen dieser Biegelinie ist im vorliegenden Falle nicht nachteilig, weil zuerst mindestens eine Decklasche und erst dann eine Seitenlasche eingefaltet wird.In one embodiment of the invention, the folding corner has the shape of an isosceles, right-angled triangle, on the long side of which the bending line is scratched. This has the advantage that the folding corner lies flat and without bulging on the side flap after the folding process. The scoring of this bending line is not disadvantageous in the present case, because at least one cover flap is folded in first and only then a side flap.

Bei AusführungsfoFmen der Erfindung weisen die Decklaschen außer dem erwähnten Versatz eine etwa rechteckige Form auf. Die Form der Seitenlaschen kann beliebig sein, lediglich im Bereich der Faltecke sollten sie eine Biegelinie aufweisen, die in einem Winkel von 45° zu der Biegelinie verläuft, um die die Seitenlasche geklappt werden kann.In Ausführungsfo F of the invention men have the cover plates other than the mentioned offset an approximately rectangular shape. The shape of the side flaps can be of any type, only in the area of the folding corner they should have a bending line which runs at an angle of 45 ° to the bending line around which the side flap can be folded.

Die Faltschachtel kann aus Kartonmaterial oder aus Kunststoff-Aluminiumverbundmaterial mit unterschiedlichen Sperreigenschaften bestehen, insbesondere aus kunststoffbeschichtetem Kartonmaterial. Im letzteren Falle können die Laschen auch durch Heißluftverschweißung miteinander verbunden sein.The folding box can consist of cardboard material or of plastic-aluminum composite material with different barrier properties, in particular of plastic-coated cardboard material. In the latter case, the tabs can also be connected to one another by hot air welding.

Befindet sich ein Klebstoffstreifen an dem oberen Rand der rechteckigen Decklasche und entlang des unteren Randes der sich verjüngenden Seitenlasche, so wird ein besonders günstiger staubdichter Verschluß erzielt. Der staubdichte Verschluß kann gleichermaßen oben und/oder unten an dem aufgestellten Schachtelzuschnitt vorgenommen sein.If there is an adhesive strip on the upper edge of the rectangular cover flap and along the lower edge of the tapered side flap, a particularly favorable dust-tight seal is achieved. The dust-tight closure can be made equally on the top and / or bottom of the box cut.

Weitere Merkmale ergeben sich aus den abhängigen Ansprüchen und aus der folgenden Beschreibung einer Ausführungsform in Verbindung mit der Zeichnung. Die einzelnen Merkmale zu können je für sich oder zu mehreren bei Ausführungsformen der Erfindung verwirklicht sein.

  • Fig. 1 zeigt eine Draufsicht auf den flachliegenden Schachtelzuschnitt;
  • Fig. 2 zeigt die aufgestellte Faltschachtel nach dem Einschlagen der unteren Decklasche;
  • Fig. 3 zeigt die aufgestellte Schachtel mit eingeschlagenen Decklaschen und noch hochgestellten Seitenlaschen.
Further features emerge from the dependent claims and from the following description of an embodiment in conjunction with the drawing. The individual features can be implemented individually or in groups in embodiments of the invention.
  • Fig. 1 shows a plan view of the flat box blank;
  • Fig. 2 shows the folded box after folding in the lower cover flap;
  • Fig. 3 shows the box set up with the cover flaps and the side flaps still raised.

Bei der in der Zeichnung dargestellten Ausführungsform der Erfindung ist in Fig. 1 die obere Hälfte einer flachliegenden Faltschachtel mit geklebter Längsnaht 1 dargestellt. Eine seitliche Wand 4 der Faltschachtel weist eine seitlich angeordnete Lasche 3 auf, auf die eine vordere Wand 2 aufgeklebt ist. Mit der vorderen Wand 2 ist über eine Biegelinie 5 eine etwa rechteckige Decklasche 6 verbunden, und über eine Biegelinie 7 ist eine Seitenlasche 8 mit der Seitenwand 4 verbunden. Die Seitenwand 4 setzt sich über die Biegelinie 7 hinaus nach oben fort, ihr oberer Rand 9 erstreckt sich etwa ein Drittel der Höhe der Lasche 8 über die Biegelinie 7 hinaus nach oben. Dieser Rand soll relativ kurz sein, damit er nach dem Falten über seine ganze Länge hinweg und damit die gesamte Faltecke 14 von der Maschine mit Leim benetzt werden kann. In diesem nach oben vorstehenden Teil der Seitenwand 4 befindet sich in Verlängerung der Randlinie 11 der Seitenlasche 8 eine Biegelinie 13, die eine Faltecke 14 abgrenzt, die durch die Biegelinie 13, 1 und den oberen Rand 9 der Seitenwand 4 gebildet ist. Die Biegelinie 13 kann auch geritzt sein. Dadurch wird gewährleistet, daß die Faltecke 14 nach dem Faltvorgang flach und ohne Wulstbildung zwischen den Laschen liegt.In the embodiment of the invention shown in the drawing, the upper half of a flat-lying folding box with glued is in Fig. 1 Longitudinal seam 1 shown. A side wall 4 of the folding box has a laterally arranged flap 3, to which a front wall 2 is glued. An approximately rectangular cover flap 6 is connected to the front wall 2 via a bending line 5, and a side flap 8 is connected to the side wall 4 via a bending line 7. The side wall 4 continues upwards beyond the bending line 7, its upper edge 9 extends approximately one third of the height of the tab 8 beyond the bending line 7 upwards. This edge should be relatively short so that it can be wetted with glue by the machine over its entire length and thus the entire folding corner 14 after folding. In this part of the side wall 4 projecting upwards, in the extension of the edge line 11 of the side flap 8, there is a bending line 13 which delimits a folding corner 14 which is formed by the bending line 13, 1 and the upper edge 9 of the side wall 4. The bending line 13 can also be scored. This ensures that the folding corner 14 after the folding process lies flat and without bulging between the tabs.

Nach dem Ausstanzen des Kartonzuschnittes wird die an die Seitenwand 4 angrenzende Lasche 3 mit der Innenseite der Schachtelwand 2 verklebt und in dieser Form dem Betrieb zugeführt, der die Faltschachtel abfüllt. In dem Betrieb wird dann die Faltschachtel aufgestellt und sowohl der Boden- als auch der Deckelverschluß folgendermaßen hergestellt. Zunächst wird die untere Decklasche 6 eingeschlagen (Fig. 2). Hierauf wird der Klebstoff in Form eines Streifens 16 in der Nähe ihres oberen Randes auf die obere Decklasche 17 aufgetragen und diese Lasche ebenfalls eingeschlagen, wobei sie mit der unteren Decklasche 6 verklebt. Bei dem Einschlagen der Decklaschen 6 und 17 legen sich die Faltecken 14 an die Innenfläche der Seitenlasche 8 und 19 an (Fig. 3). Auf die Innenfläche der zuvor etwas abgespreizten Seitenlaschen 8 und 19 und auf die Außenflächen der an diesen anliegenden Faltecken 14 wird dann ein an die Biegelinie 7 angrenzender Klebstoffstreifen 20 aufgetragen. Werden die Seitenlaschen 8 und 19 dann eingeschlagen, so legen sie sich auf die Außenfläche der oberen Decklasche 17 an und der auf die Seitenlasche und die äußere Fläche der Faltecke aufgebrachte Klebstoffstreifen 20 verklebt auch die Seitenlaschen 8, 19 staubdicht mit der Decklasche 17.After the cardboard blank has been punched out, the tab 3 adjoining the side wall 4 is glued to the inside of the box wall 2 and in this form is fed to the company which fills the folding box. The folding box is then set up in the company and both the bottom and the lid closure are produced as follows. First the lower cover flap 6 is hammered in (FIG. 2). The adhesive is then applied in the form of a strip 16 near its upper edge to the upper cover flap 17 and this flap is also hammered in, whereby it sticks to the lower cover flap 6. When the cover flaps 6 and 17 are turned in, the fold corners 14 lie against the inner surface of the side flaps 8 and 19 (FIG. 3). An adhesive strip 20 adjoining the bending line 7 is then applied to the inner surface of the side flaps 8 and 19 which have previously been slightly spread apart and to the outer surfaces of the fold corners 14 adjoining them. If the side flaps 8 and 19 are then hammered in, they lie on the outer surface of the upper cover flap 17 and the adhesive strip 20 applied to the side flap and the outer surface of the folding corner also glues the side flaps 8, 19 to the cover flap 17 in a dust-tight manner.

Die untere Decklasche 6 und/oder die obere Decklasche 17 weist an ihrem in Verlängerung der Längsnaht 1 verlaufenden seitlichen Rand 21 an ihren in Fig. 1 oberen freien Rand 22 anschließend einen kleinen Ausschnitt 23 (Versatz) auf. Die Decklasche 6 kann sich daher eng an die Anlenkung der Seitenlasche 8 anschmiegen. Dadurch ist nach dem Umfalten der Seitenlasche die Faltschachtel schon mittels eines Leimpunktes rieseldicht.The lower cover flap 6 and / or the upper cover flap 17 then has a small cutout 23 (offset) on its side edge 21 extending in the longitudinal seam 1 and on its free edge 22 shown in FIG. 1. The cover plate 6 can therefore nestle closely against the articulation of the side plate 8. As a result, after folding the side flap, the folding box is already leak-tight using a glue point.

Die Seitenlasche 8 kann im Bereich oberhalb der Faltecke 14 in Form und Größe variabel sein. Dieser Teil hat keinen Einfluß auf die Funktion der Staubdichtigkeit. Sie muß sich dort nicht mehr weiter verjüngen. Als Abschluß dieser Lasche 8 kann jede beliebige Größe und Form gewählt werden. Um genügend Platz für den Klebestreifen 20 zu bieten, weist sie bei Ausführungsformen der Erfindung eine Höhe von mindestens 10 mm auf. Die Länge der Kante 9 kann bei Ausführungsformen der Erfindung ca. 7 mm betragen.The side flap 8 can be variable in shape and size in the area above the folding corner 14. This part has no influence on the function of the dust tightness. It no longer has to rejuvenate there. At the end of this tab 8, any size and shape can be selected. In order to provide sufficient space for the adhesive strip 20, it has a height of at least 10 mm in embodiments of the invention. The length of the edge 9 can be approximately 7 mm in embodiments of the invention.

Bei Einsatz eines kunststoffbeschichteten Kartonmaterials läßt sich auch die Technik der Heißluftverschweißung anwenden. Aufgrund der guten Dichteigenschaften der erfindungsgemäßen Faltschachtel kann diese für pulverförmige Produkte und auch für pastöse Produkte verwendet werden. Die erfindungsgemäße Faltschachtel kann auf herkömmlichen Aufrichte- und Kartonierautomaten ohne besondere Probleme verarbeitet werden.When using a plastic-coated cardboard material, the technique of hot air welding can also be used. Because of the good sealing properties of the folding box according to the invention, it can be used for powdery products and also for pasty products. The folding box according to the invention can be processed on conventional erecting and cartoning machines without any particular problems.
