Abstract

The cardboard blank has a longitudinal seam and four end wall flaps, of which the one in the region of the longitudinal seam is of double construction. One of the end wall flaps lying one above the other each case is linked in each case to a side wall, thus forming the longitudinal seam likewise lying one above the other. The adjacent end wall flaps are not completely separated from one another, with the result that a closure membrane can be sealed on without interruption. <IMAGE>

Description

Die Erfindung betrifft eine Faltschachtel, die aus einem einteiligen Zuschnitt aus Karton od. dgl. aufgerichtet und entlang einer Längsnaht verschlossen ist, wobei die Längsnaht durch wenigstens teilweise Überlappung zweier Seitenwände gebildet ist, sowie mit an beiden Stirnseiten angeordneten, an den vier Seitenwänden angelenkten Stirnwandklappen, auf deren Innenseite eine Membran oder dgl. aufgesiegelt ist und die außerhalb ihrer Anlenklinien an den Seitenwänden wenigstens geringfügig miteinander verbunden sind.The invention relates to a folding box, which is erected from a one-piece blank of cardboard or the like and is closed along a longitudinal seam, the longitudinal seam being formed by at least partially overlapping two side walls, and with end wall flaps arranged on both end faces and articulated on the four side walls , on the inside of which a membrane or the like is sealed and which are at least slightly connected to one another outside their articulation lines on the side walls.

Eine solche, aus der DE-PS 959807 bekannte Faltschachtel ist durch die Ausgestaltung der Stirnwandklappen und die Anordnung der Membran verhältnismäßig dicht. Lediglich im Bereich der Längsnaht kommen gelegentlich Undichtigkeiten vor.Such a folding box known from DE-PS 959807 is relatively tight due to the design of the end wall flaps and the arrangement of the membrane. Leakages only occasionally occur in the area of the longitudinal seam.

Der Erfindung liegt nun die Aufgabe zugrunde, die Faltschachtel so auszugestalten, daß auch diese Undichtigkeiten im Bereich der Längsnaht ausgeschlossen werden.The invention is based on the object of designing the folding box in such a way that these leaks in the area of the longitudinal seam are also excluded.

Dazu wird erfindungsgemäß vorgeschlagen, daß auch an der die Überlappung mit einer Seitenwand bildenden Seitenwandfläche im Bereich jeder Stirnseite je eine Stirnwandklappe angelenkt ist, die außerhalb ihrer Anlenklinien an der Seitenwandfläche mit der benachbarten Stirnwandklappe wenigstens geringfügig verbunden sind.For this purpose, it is proposed according to the invention that an end wall flap is also articulated on the side wall surface forming the overlap with a side wall in the region of each end side, which end flaps are at least slightly connected to the adjacent end wall flap outside their articulation lines on the side wall surface.

Dadurch wird beim Aufsiegeln der Membran die Stirnseite in allen vier Ecken absolut dicht verschlossen.As a result, when sealing the membrane, the end face is sealed absolutely tight in all four corners.

Eine besonders vorteilhafte Ausgestaltung der Erfindung liegt darin, daß die zur Bildung der Längsnaht innen liegende Seitenwand wenigstens teilweise doppellagig ausgebildet ist, wobei die zweite Lage zwischen die beiden Seitenwände eingefaltet ist.A particularly advantageous embodiment of the invention is that the inner side wall to form the longitudinal seam is at least partially double-layered, the second layer being folded between the two side walls.

Dadurch wird wirksam verhindert, daß eine offene Schnittkante mit dem Füllgut der Faltschachtel in Verbindung tritt, wodurch eine weitere Undichtigkeit ausgeschlossen ist.This effectively prevents an open cut edge from coming into contact with the contents of the folding box, which prevents further leaks.

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

Fig. 1
einen flachliegenden Kartonzuschnitt
Fig. 2
eine Faltschachtel, gebildet aus dem Kartonzuschnitt gemäß Fig. 1 mit versiegelter Längsnaht und noch offener Stirnseite und
Fig. 3
einen Schnitt durch die Faltschachtel im Bereich der Längsnaht in vergrößertem Maßstab.
The invention is illustrated in the drawing using an exemplary embodiment. Show:
Fig. 1
a flat cardboard blank
Fig. 2
a folding box, formed from the cardboard blank according to FIG. 1 with sealed longitudinal seam and still open front and
Fig. 3
a section through the folding box in the area of the longitudinal seam on an enlarged scale.

Mit 1 ist in Fig. 1 ein Kartonzuschnitt bezeichnet, der fünf Seitenwände 2,3,4,5 und 6 aufweist, von denen die beiden äußeren 2 und 6 beim Aufrichten unter Bildung einer Längsnaht zusammengesiegelt werden.1 in FIG. 1 denotes a cardboard blank which has five side walls 2, 3, 4, 5 and 6, of which the two outer 2 and 6 are sealed together when erected to form a longitudinal seam.

An jeder der Seitenwände ist an ihren beiden gegenüberliegenden Kanten je eine Stirnwandklappe 7 bis 16 über zwei durchlaufende Rillinien 17 und 18 angelenkt. Zwischen jeweils zwei benachbarten Seitenwänden ist ebenfalls je eine Rillinie 19,20,21 und 22 vorgesehen. Diese Rillinien erstrecken sich bis in die Stirnwandklappen hinein, während Einschnitte 23 bis 30 zwischen den einzelnen Stirnwandklappen mit Abstand von den Rillinien 17 bzw. 18 enden.On each of the side walls, an end wall flap 7 to 16 is articulated on its two opposite edges via two continuous crease lines 17 and 18. A crease line 19, 20, 21 and 22 is also provided between each two adjacent side walls. These creasing lines extend into the end wall flaps, while incisions 23 to 30 between the individual end wall flaps end at a distance from the creasing lines 17 and 18, respectively.

An der Seitenwand 2 ist über eine Ritzlinie 31 eine zweite Lage 32 der Seitenwand angeformt, die auf deren Außenseite aufgefaltet wird.A second layer 32 of the side wall is formed on the side wall 2 via a score line 31 and is folded out on the outside thereof.

In Fig. 2 ist der Kartonzuschnitt zu einer Verpackungshülse aufgerichtet und die Längsnaht durch Aufeinandersiegeln der beiden Seitenwände 2 und 6 verschlossen. Wie besonders aus Fig. 3 ersichtlich, ist dabei die zweite Lage 32 auf die Außenseite der Seitenwand 2 aufgefaltet und damit zwischen die beiden Seitenwände eingeklemmt. Die Schnittkante 33 ist somit abgedeckt und das Füllgut kann nicht mit ihr in Kontakt treten.In Fig. 2 the cardboard blank is erected into a packaging sleeve and the longitudinal seam is closed by sealing the two side walls 2 and 6 together. 3, the second layer 32 is unfolded onto the outside of the side wall 2 and thus clamped between the two side walls. The cutting edge 33 is thus covered and the filling material cannot come into contact with it.

An ihren beiden Stirnseiten wird die Faltschachtel mit einer nicht dargestellten Membran abgedichtet. Dazu werden, wie in Fig. 2 dargestellt, die Stirnwandklappen um annähernd 90 Grad nach außen umgebogen und dann die Membran auf diese aufgesiegelt.The folding box is sealed at its two end faces with a membrane, not shown. For this purpose, as shown in FIG. 2, the end wall flaps are bent outwards by approximately 90 degrees and then the membrane is sealed onto them.

Beim Umfalten der Stirnwandklappen nach außen werden zwar in dem nicht aufgetrennten Bereich zwischen zwei benachbarten Stirnwandklappen die einzelnen Kartonfasern gestreckt; es tritt jedoch kein Aufreißen des Kartons ein, so daß auch in diesem Bereich eine dichte Siegelung stattfindet.When the end flaps are folded outwards, the individual cardboard fibers are stretched in the area that is not separated between two adjacent end wall flaps; however, the carton does not tear open, so that a tight seal also takes place in this area.

Claims (2)

  1. Folding carton, which is erected as a parallelelepided from a single-piece blank made of board or a similar material and is closed along a longitudinal seam, where the longitudinal seam is formed by two side panel sections (2,6) that overlap at least to some extent, and with end panel flaps (8 to 11, 13 to 16) provided at both ends that are hinged to the four side panels (3 to 6), to the inside of which a membrane etc. is sealed and which are joined at least slightly outside the line (17, 18) hinging them to the side panels, wherein an end panel flap (7,12) is also hinged to the side panel section (2), that forms the overlap with a side panel 6, in the area of each end, this flap being joined to the adjacent end panel flap (8,13) at least slightly outside the line (17,18) hinging it to the side panel section (2).
  2. Folding carton according to claim 1, wherein the side panel (2) located on the inside when the longitudinal seam is formed consists at least partially of two layers (layer 32), the second layer (32) being folded in between the two side panels (2,6).
