Abstract

The folding container has a bottom (2) and four side walls (3, 4, 5, 6) which can be connected to one another by in each case two foldably arranged gusset portions, a tab (12) being moulded on to in each case one of the gusset portions (7, 8). When the side walls have been folded upright, the tab lies on the outside of the one side wall and is fixed there. This fixing is effected particularly favourably by cutting lines (15, 16) in the side wall, in which cutting lines the tab engages and is hooked. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Faltbehälter aus einem einteiligen Kartonzuschnitt mit einem Boden und vier daran angelenkten Seitenwänden, wobei jeweils zwei zueinander benachbarte Seitenwände untereinander durch jeweils zwei faltbar angeordnete Zwickel-Abschnitte verbunden sind, von denen jeweils einer mit einem angeformten Lappen versehen ist, der nach dem Hochfalten der Seitenwände in Schnittlinien in einer der beiden benachbarten Seitenwände eingreift.The invention relates to a folding container made of a one-piece cardboard blank with a bottom and four side walls articulated thereon, two adjacent side walls being connected to one another by two foldable gusset sections, one of which is provided with a molded tab which after folding up the side walls engages in cut lines in one of the two adjacent side walls.

Ein derartiger Faltbehälter ist aus der FR-A-778456 bekannt, wobei allerdings das Einfädeln der Lappen in die entsprechende Schnittlinie sehr kompliziert ist.Such a folding container is known from FR-A-778456, but threading the tabs into the corresponding cutting line is very complicated.

Der Erfindung liegt die Aufgabe zugrunde, einen Faltbehälter der eingangs genannten Art zu schaffen, der einfach und unkompliziert aufzurichten ist und trotzdem nicht unbeabsichtigt zusammenklappen kann.The invention has for its object to provide a folding container of the type mentioned, which is easy and straightforward to erect and still cannot accidentally fold.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß jeweils zwei ständig im Abstand von einander angeordnete Schnittlinien vorgesehen sind, die in ihrem Mittelabschnitt auf einander zu verlaufen, und daß der Lappen in seinem Mittelabschnitt eine etwas größere Breite aufweist als in seinen Endabschnitten und mit diesem Mittelabschnitt hinter die von den beiden Schnittlinien abgegrenzten Seitenwandabschnitte greift.This object is achieved in that in each case two cutting lines arranged at a distance from one another are provided, which run towards one another in their central section, and in that the tab has a somewhat larger width in its central section than in its end sections and with this middle section engages behind the side wall sections delimited by the two cutting lines.

Durch diese Ausgestaltung ist ein einfaches Eindrücken der Lappen in die zugehörigen Schnittlinien möglich, ohne daß es eines umständlichen Einfädelns bedarf. Die Lappen erhalten dabei einen sehr guten Halt, wodurch der Faltbehälter sehr stabil ist.This configuration enables the flaps to be simply pressed into the associated cutting lines without the need for laborious threading. The rags get a very good hold, which makes the folding container very stable.

Das Eindrücken des jeweiligen Lappen in die Schnittlinien wird noch weiter erleichtert, wenn erfindungsgemäß im Bereich der Lappen in den Seitenwänden weitere Einschnitte vorgesehen sind, welche zusammen mit den ersten Schnittlinien ein im wesentlichen doppel-T-förmiges Schnittmuster ergeben.Pressing the respective tab into the cutting lines is made even easier if, according to the invention, further incisions are provided in the side walls in the area of the tabs, which together with the first cutting lines result in an essentially double-T-shaped cutting pattern.

Sehr vorteilhaft ist es auch, wenn erfindungsgemäß der Lappen mit einer parallel zu seiner Anlenklinie am Zwickel-Abschnitt verlaufenden Faltlinie versehen ist.It is also very advantageous if, according to the invention, the flap is provided with a fold line running parallel to its articulation line on the gusset section.

Mit dieser Ausgestaltung kann der Lappen einfach auf die Schnittlinien-Anordnung aufgelegt und durch leichten Druck eingedrückt werden.With this configuration, the flap can simply be placed on the cutting line arrangement and pressed in by light pressure.

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

Fig. 1
einen flachliegenden Kartonzuschnitt und
Fig. 2
eine schaubildliche Darstellung eines aus dem Zuschnitt nach Fig. 1 aufgerichteten Faltbehälters.

The invention is illustrated in the drawing using an exemplary embodiment. Show:
Fig. 1
a flat cardboard blank and
Fig. 2
a diagrammatic representation of a folding container erected from the blank according to FIG. 1.

Mit 1 ist in Fig. 1 ein Kartonzuschnitt bezeichnet, der einen Boden 2 und ― an diesem angelenkt ― vier Seitenwände 3, 4, 5 und 6 aufweist. Zwischen den Seitenwänden sind jeweils zwei Zwickel-Abschnitte 7, 8 angeordnet, die über Faltlinien 9, 10 mit den Seitenwänden und über eine Faltlinie 11 untereinander verbunden sind.1 in FIG. 1 denotes a cardboard blank which has a base 2 and - hinged to it - four side walls 3, 4, 5 and 6. Two gusset sections 7, 8 are arranged between the side walls, which are connected to the side walls via fold lines 9, 10 and to one another via a fold line 11.

Der an der Seitenwand 4 bzw. 6 angelenkte Zwickel-Abschnitt 7 entspricht in seiner Länge der Höhe dieser Seitenwand, während der Zwickel-Abschnitt 8 kürzer ist. In den dadurch freigelassenen Raum ragt ein Lappen 12 hinein, der an den Zwickel-Abschnitt 7 angeformt und mit einer Faltlinie 13 versehen ist.The gusset section 7 articulated on the side wall 4 or 6 corresponds in length to the height of this side wall, while the gusset section 8 is shorter. A tab 12 protrudes into the space thus left, which is formed on the gusset section 7 and provided with a fold line 13.

In den beiden Seitenwänden 3 und 5 sind zwei etwa doppel-T-förmige Schnittmuster 14 vorgesehen, die aus zwei etwa parallel verlaufenden Schnittlinien 15 und 16 sowie einem diese verbindenden Einschnitt 17 gebildet sind.In the two side walls 3 and 5, two approximately double-T-shaped cutting patterns 14 are provided, which are formed from two approximately parallel cutting lines 15 and 16 and an incision 17 connecting them.

Die Seitenwand 4 ist an ihrem freien Rand mit zwei Kerben 18, 19 versehen, von denen zwei Aufreißlinien 20, 21 zur Anlenklinie der Seitenwand 4 am Boden 2 verlaufen. Dadurch ist ein Abschnitt 24 von der Seitenwand abgeteilt, der entlang der beiden Aufreißlinien ablösbar ist.The side wall 4 is provided on its free edge with two notches 18, 19, two of which tear lines 20, 21 extend to the articulation line of the side wall 4 on the bottom 2. As a result, a section 24 is separated from the side wall and can be detached along the two tear lines.

In Fig. 2 ist aus dem Kartonzuschnitt ein Faltbehälter 22 aufgerichtet, in dem die Seitenwände 3, 4, 5 und 6 hochgefaltet sind. Die beiden Zwickel-Abschnitte sind um die Faltlinie 10 aufeinandergefaltet, wodurch nur der außenliegende Abschnitt 7 sichtbar ist. Der an diesem Abschnitt 7 angeformte Lappen 12 ist im Bereich der beiden Schnittlinien 15 und 16 hinter die Seitenwand 3 bzw. 5 eingeschoben, wobei ― wie bei der Seitenwand 5 sichtbar ― nur zwei sehr kleine Abschnitte des Lappens 12 ins Innere des Faltbehälters 22 ragen.In Fig. 2 a folding container 22 is erected from the cardboard blank, in which the side walls 3, 4, 5 and 6 are folded up. The two gusset sections are folded together about the fold line 10, so that only the outer section 7 is visible. The flap 12 formed on this section 7 is inserted in the area of the two cutting lines 15 and 16 behind the side wall 3 and 5, whereby - as can be seen in the side wall 5 - only two very small sections of the flap 12 protrude into the interior of the folding container 22.

Aufgrund der Form der Schnittlinien 15, 16 sowie der Verbreiterung des Lappens 12 ist damit trotzdem ein ausreichender Halt des Lappens gewährleistet.Due to the shape of the cutting lines 15, 16 and the widening of the flap 12, a sufficient hold of the flap is nevertheless ensured.

Claims (3)

1. Folded container made from a single-piece board blank (1), with a base (2) to which four side panels (3, 4, 5, 6) are hinged, each pair of adjacent side panels being connected by a pair of gusset sections (7, 8) that are folded into place, one section of which being provided with a tab (12), which engages cut lines (15, 16) in one of the two adjacent side panels (3, 5) once the side panels have been folded upwards, wherein cut lines (15, 16) are provided in pairs constantly located a distance apart, the middle sections of which extend towards each other, and wherein the middle section of the tab (12) is somewhat wider than its end sections and locks behind the side panel sections defined by the two cut lines (15, 16).
2. Folded container according to claim 1, wherein further cuts (17) are provided in the side panels (3, 5) in the area of the tabs (12), which together with the first cut lines (15, 16) represent an essentially double T-shaped cut pattern (14).
