Abstract

The container has a polygonal bottom and folding-up side walls which are attached individually to the bottom. The side walls are held by a frame which is placed around them on the outside, and from which the inside container, formed from the bottom and the side walls, can be pulled out, after which the side walls can be opened out. <IMAGE>

Description

Die Erfindung betrifft einen Behälter mit einem Boden und auffaltbaren Seitenwänden. Derartige Behälter sind in einer Vielzahl bekannt; allen gemeinsam ist aber, daß sich aus ihnen das Füllgut nur schwierig entnehmen läßt. Der Behälter muß dazu im Wandbereich aufgerissen werden, um eine Zugäng­lichkeit des Füllgutes zu erreichen.The invention relates to a container with a bottom and foldable side walls. A large number of such containers are known; Common to all, however, is that it is difficult to remove the contents from them. For this purpose, the container must be torn open in the wall area in order to ensure that the filling material is accessible.

Hier setzt die Erfindung ein; ihr liegt die Aufgabe zugrun­de, einen Behälter zu schaffen, der einerseits das Füllgut gut und einigermaßen dicht umschließt, der andererseits aber leicht zu öffnen ist.This is where the invention comes in; it is based on the task of creating a container which, on the one hand, encloses the filling good and reasonably tightly, but on the other hand is easy to open.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine Vielzahl von einzelnen Seitenwänden vorgesehen ist, die jeweils einzeln am Boden angelenkt und vollständig von einander getrennt sind, und daß die Seitenwände von einer Zarge umgeben sind.This object is achieved in that a plurality of individual side walls is provided, each articulated individually on the floor and completely separated from one another, and that the side walls are surrounded by a frame.

Zum Öffnen des Behälters braucht lediglich die Zarge nach unten geschoben werden, worauf die Seitenwände nach außen geklappt werden können und dann mit dem Boden in einer Ebene liegen. Ein besonders stabiler und dichter Behälter ergibt sich, wenn erfindungsgemäß die Zarge in ihrer Breite der Höhe der Seitenwände entspricht. Dabei deckt die Zarge die Trennlinien zwischen den Seitenwänden wirksam ab, so daß die sich dort ergebenden Undichtigkeiten weitgehend beseitigt sind.To open the container, the frame only needs to be pushed down, whereupon the side walls can be folded outwards and then lie in one plane with the floor. A particularly stable and tight container is obtained if, according to the invention, the width of the frame corresponds to the height of the side walls. The frame effectively covers the dividing lines between the side walls, so that the resulting leaks are largely eliminated.

Sehr vorteilhaft ist es auch, wenn erfindungsgemäß die Zarge als ununterbrochenes Band ausgebildet ist. Dadurch erhält der Behälter trotz einzelner Seitenwände eine runde oder ovale Außenform, ohne daß komplizierte Verformungen des Behälters notwendig würden.It is also very advantageous if the frame is designed as an uninterrupted hinge according to the invention. This gives the container a round or oval outer shape despite individual side walls, without complicated deformations of the container being necessary.

Erfindungsgemäß kann die Zarge jedoch auch durch Faltlinien in mehrere Abschnitte unterteilt sein, die in ihrer Länge der Breite der jeweiligen Seitenwände entsprechen. Damit bleibt die durch die Gestaltung des Bodens und der Seiten­wände vorbestimmte Form auch nach dem Anbringen der Zarge erhalten.According to the invention, however, the frame can also be divided into several sections by folding lines, the length of which corresponds to the width of the respective side walls. The shape predetermined by the design of the base and the side walls is thus retained even after the frame has been attached.

Eine vorteilhafte Ausgestaltung der Erfindung liegt darin, daß am oberen freien Ende von wenigstens zwei einander gegenüberliegenden Seitenwänden je ein Lappen angeformt ist. Diese beiden Lappen können verschiedene Funktionen über­nehmen. So ist es beispielsweise möglich, den Behälter mit Boden und Seitenwänden an diesen Lappen aus der Zarge her­auszuheben. Darüber hinaus können die beiden Lappen zur Sicherung eines Stülpdeckels dienen, der mit einem Rand über die beiden Lappen greift.An advantageous embodiment of the invention is that a tab is formed on the upper free end of at least two opposite side walls. These two tabs can perform different functions. For example, it is possible to lift the container with the bottom and side walls out of the frame using these tabs. In addition, the two tabs can be used to secure a slip lid, which engages with an edge over the two tabs.

Eine weitere erfindungsgemäße Ausgestaltung liegt darin, daß jede der Seitenwände über eine Faltlinie mit einem Lappen verbunden ist. Diese Lappen können nach außen abgebogen als Verzierung des Behälters dienen, haben darüber hinaus aber auch die vorher beschriebenen Funktionen.Another embodiment of the invention is that each of the side walls is connected to a rag via a fold line. These tabs can be used to decorate the container, but also have the functions described above.

In diesem Zusammenhang kann es sehr vorteilhaft sein, wenn erfindungsgemäß die Zarge an ihrem oberen Rand mit einem umlaufenden, nach außen abstehenden Bund versehen ist, der unter die nach außen abgebogenen Lappen der Seitenwände greift. Hierdurch erhalten die Lappen eine zusätzliche Abstützung und Versteifung.In this context it can be very advantageous if, according to the invention, the frame is provided on its upper edge with a circumferential, outwardly projecting collar which engages under the outwardly bent tabs of the side walls. This gives the flaps additional support and stiffening.

In der Zeichnung ist die Erfindung anhand von zwei Ausfüh­rungsbeispielen veranschaulicht. Dabei zeigen:

  • Fig. 1 eine Ansicht eines flachliegenden Kartonzuschnit­tes mit einem vieleckigen Boden,
  • Fig. 2 ein Schaubild eines Behälters aus dem Kartonzu­schnitt gemäß Fig. 1 aufgerichtet,
  • Fig. 3 einen weiteren Kartonzuschnitt mit einem achteckigen Boden und
  • Fig. 4 einen aus dem Zuschnitt gemäß Fig. 3 aufgerichteten Behälter in perspektivischer An­sicht.
The invention is illustrated in the drawing using two exemplary embodiments. Show:
  • 1 is a view of a flat cardboard blank with a polygonal bottom,
  • 2 shows a diagram of a container erected from the cardboard blank according to FIG. 1,
  • Fig. 3 shows another cardboard blank with an octagonal bottom and
  • FIG. 4 shows a container erected from the blank according to FIG. 3 in a perspective view.

Mit 1 ist in Fig. 1 ein flachliegender Kartonzuschnitt bezeichnet, der einen Boden 2 aufweist, der vieleckig ausge­bildet ist und von vierzehn Faltlinien begrenzt wird. über diese Faltlinien 3 sind ebenfalls vierzehn Seitenwände 4 am Boden 2 angelenkt. An jeder dieser Seitenwände 4 ist über eine weitere Faltlinie 5 ein Lappen 6 angeformt.1 in Fig. 1 is a flat cardboard blank, which has a bottom 2, which is polygonal and is delimited by fourteen fold lines. Fourteen side walls 4 are also articulated on the bottom 2 via these folding lines 3. A flap 6 is formed on each of these side walls 4 via a further folding line 5.

Beim in Fig. 2 aufgerichtet dargestellten Behälter sind die Seitenwände 4 von einer Zarge 7 umgeben, welche durch eine Längsnaht 9 verschlossen ist und die Seitenwände in ihrer aufgerichteten Stellung fixiert. Die Zarge 7 ist an ihrem oberen Rand mit einem umlaufenden Bund 8 versehen, auf dem sich die nach außen abgebogenen Lappen 6 abstützen.In the container shown erected in FIG. 2, the side walls 4 are surrounded by a frame 7 which is closed by a longitudinal seam 9 and fixes the side walls in their erected position. The frame 7 is provided at its upper edge with a circumferential collar 8 on which the tabs 6 bent outwards are supported.

Beim Ausführungsbeispiel nach Fig. 3 ist der Boden 12 des Zuschnittes 11 achteckig ausgebildet und durch acht Falt­linien 13 begrenzt. Diese Faltlinien 13 sind die Verbin­dungslinien für Seitenwände 14, die untereinander nur über den Boden verbunden sind.3, the bottom 12 of the blank 11 is octagonal and is delimited by eight fold lines 13. These fold lines 13 are the connecting lines for side walls 14, which are connected to one another only via the floor.

An zwei einander gegenüberliegenden Seitenwänden 14 ist über zwei weitere Faltlinien 15 je ein Lappen 16 angeformt.A flap 16 is formed on two opposite side walls 14 via two further fold lines 15.

Im aufgerichteten Zustand des im Fig. 4 dargestellten Behäl­ters sind die Seitenwände 14 von einer Zarge 17 umgeben, die durch Faltlinien 18 in einzelne Abschnitte 19 unterteilt ist, die in ihren Abmessungen denen der Seitenwände 17 entsprechen.In the erected state of the container shown in FIG. 4, the side walls 14 are surrounded by a frame 17 which is divided into individual sections 19 by folding lines 18, the dimensions of which correspond to those of the side walls 17.

Die beiden Lappen 16 ragen oben aus der Zarge 17 heraus und dienen zum Herausziehen des aus Boden und Seitenwänden bestehenden Innenbehälters aus der Zarge.The two tabs 16 protrude from the top of the frame 17 and are used to pull the inner container consisting of the bottom and side walls out of the frame.
