Abstract

When horizontal, two opposing sides (3) partly cover one another and the covered or overlapped part of the underlying sidewall (3) is fitted with projecting and rearward projections (21,22) as opposed to the covering or top part of the upper sidewall which is suitably shaped on its underside so the two parts once overlapped make one wall thickness. The two parts of the respective sidewalls fit positively together and the projections come in strip form forward and in pocket and/or slot form to the rear and thus home into recesses in the other sidewall in each case. With the wall upended, the projections on the top end edge of the wall form horizontal support surfaces for the overlying container. The projections have interposed support ribs transverse to the projections to slot home into the slots or pockets etc. as provided in the other sidewall. The slots or rearward projections are preferably corrugated and a stop strip on the vertical side of the upended wall is addressed by the inner side of the strip on the other sidewall. The stop strip is offset from the associated wall edge to give a distance of one stop strip wall thickness from the vertical edge of the respective wall.

Description

Die Erfindung betrifft einen Klappbehälter mit vier senkrechten Seitenwänden, die an einer Bodenplatte angelenkt und jeweils nach innen hin in eine waagerechte Lage schwenkbar sind, wobei zwei einander gegenüberliegende Seitenwände in ihrer waagerechten Lage einander teilweise überdecken (GB-A-2063220).The invention relates to a folding container with four vertical side walls attached to a floor slab articulated and inward in a horizontal Location are pivotable, with two opposite side walls partially overlap each other in their horizontal position (GB-A-2063220).

Es ist bekannt, die zwei senkrechten Seitenwände an den Schmalseiten eines Klappbehälters um die untere waagerechte Anlenkachse nach innen zu klappen, bis sie auf der Bodenplatte aufliegen. Danach werden die zwei Seitenwände der Längsseiten nach innen darübergeklappt. Im aufgerichteten Zustand liegen die Seitenwände der Schmalseiten an einer senkrechten Anschlagleiste am Rand der anderen Seitenwände an, wobei diese Anschlagleiste nach innen vorspringt und nach dem Hochklappen der Seitenwände der Längsseiten die Seitenwände der Schmalseiten an der Anschlagleiste formschlüssig anliegen.It is known that the two vertical side walls on the Narrow sides of a folding container around the lower one to fold the horizontal pivot axis inwards until it opens rest on the base plate. After that, the two Side walls of the long sides folded inwards. in the the side walls of the erect state Narrow sides on a vertical stop bar at the edge of the other side walls, this stop bar protrudes inwards and after folding up the Sidewalls of the long sides the sidewalls of the Form-fit the narrow sides of the stop bar.

Die zwei Seitenwände der Längsseiten weisen meist eine Höhe auf, die größer ist als die halbe Breite der Bodenplatte, so daß sie übereinander liegen und hierdurch die Gesamthöhe des Behälters im zusammengeklappten Zustand erhöhen.The two side walls of the long sides usually have one Height that is greater than half the width of the Base plate so that they lie on top of each other and thereby the total height of the container in increase folded state.

Aufgabe der Erfindung ist es, einen Klappbehälter der eingangs genannten Art so zu verbessern, daß bei einfacher Konstruktion, geringem Materialverbrauch und geringen Abmessungen die Höhe der aufeinanderliegenden Seitenwände im überlappenden Bereich gering ist, ohne die Stabilität der Seitenwände wesentlich zu verringern.The object of the invention is to provide a folding container improve the type mentioned so that at simple construction, low material consumption and small dimensions the height of the superimposed Side walls in the overlapping area is small without the Significantly reduce the stability of the side walls.

Auch ist es Aufgabe der Erfindung, an den einander überlappenden Seitenwänden den oberen waagerechten Stapelrand, auf dem der daraufstehende Behälter aufliegt, mit einer genügend großen, insbesondere durchgehend verlaufenden Auflagenfläche zu versehen.It is also an object of the invention to each other overlapping side walls the upper horizontal Edge of the stack on which the container on top rests with a sufficiently large, especially continuous running surface to provide.

Diese Aufgaben werden erfindungsgemäß dadurch gelöst, daß der überdeckte Bereich der darunterliegenden Seitenwand auf seiner Oberseite Vor- und Rücksprünge aufweist und der überdeckende Bereich der darüberliegenden Seitenwand an seiner Unterseite entsprechend derart geformt ist, daß die beiden einander überdeckenden Bereiche in ihrer Gesamtdicke der Dicke einer Seitenwand entsprechen.These objects are achieved in that of the covered area of the underlying side wall its top has projections and recesses and the overlapping area of the overlying side wall is shaped in accordance with its underside in such a way that the two overlapping areas in their Total thickness correspond to the thickness of a side wall.

Hierdurch wird im überlappenden Bereich eine Gesamthöhe beider übereinander liegender Seitenwände erzielt, die gleich der Höhe bzw. Dicke einer Seitenwand ist oder nur unwesentlich höher bzw. dicker. Dabei bleibt die Stabilität der Seitenwände erhalten und dem oben daraufstehenden Behälter wird eine genügend große Auflagefläche geboten.This creates a total height in the overlapping area both superimposed side walls achieved the is equal to or only the height or thickness of a side wall slightly higher or thicker. The remains Maintain stability of the side walls and the above the container standing on it becomes a sufficiently large one Support area offered.

Eine besonders hohe Stabilität und eine geringe Höhe werden erreicht, wenn die beiden Bereiche formschlüssig ineinander liegen.A particularly high stability and a low height are achieved when the two areas are form-fitting lie in one another.

Besonders vorteilhaft ist es, wenn die Vorsprünge leistenfömig sind und in taschenförmigen und/oder schlitzförmigen Rücksprüngen, insbesondere Ausnehmungen der andern Seitenwand einliegen. Hierbei können bei senkrecht aufgestellter Seitenwand die Vorspünge an dem oberen waagerechten (stirnseitigen) Rand (25) der Seitenwand waagerechte Auflageflächen für einen darüberstehenden Behälter bilden.It is particularly advantageous if the projections are strip-shaped and in pocket-shaped and / or slit-shaped recesses, in particular recesses the other side wall. Here, at the projections on the upper horizontal (front) edge (25) of the Side wall horizontal contact surfaces for one Form the container above.

Hierdurch ist ein durchgehender Stapelrand möglich. Der Behälterrand ist so ausgestaltet, daß die untenliegende Seitenwand im Bereich des Oberrandes um eine Wandstärke zurückgenommen wurde und innerhalb des Einstapelrandes taschenförmig, zum Behälterboden zeigend, eine durchgehende Ausnehmung besitzt, in der partiell Stützrippen eingebracht sind, die den Stapelrand abstützen.This enables a continuous stacking edge. Of the The edge of the container is designed so that the bottom Side wall in the area of the upper edge by one wall thickness was withdrawn and within the stacking margin pocket-shaped, pointing to the bottom of the container, one has a continuous recess in the partial Support ribs are introduced, which the stack edge support.

Auf der Seitenwand, die als zweites eingeklappt wird, ist die Tasche entsprechend nach außen geformt (nahc oben zeigend) und mit nach innen gerichteten bzw. nach unten zeigenden Stützrippen der Stapelrand abgestützt. Es tauchen nun die Stapelränder in die jeweiligen Taschen ein. Die Stützrippen tauchen in entsprechende Ausnehmungen im Stapelrand und den Stapelbegrenzungen ein. Somit wird erreicht, daß ein Stapelrand mit seitlicher Begrenzung über annähernd die gesamte Wandtiefe ausgebildet werden kann und ein Überlappen von Seitenwänden trotzdem möglich ist.On the side wall, which is folded in second, is the bag is shaped accordingly to the outside (near the top pointing) and with inward or downward supporting ribs supported the stack edge. It now dip the stack edges into the respective pockets on. The support ribs dip into corresponding ones Recesses in the stack edge and the stack boundaries on. It is thus achieved that a stack edge with lateral limitation over almost the entire Wall depth can be formed and an overlap of Sidewalls is still possible.

Damit wird auch vorgeschlagen, daß zwischen den Vorsprüngen quer zu diesen verlaufende Stützrippen (26) angeordnet sind, die bei aufeinanderliegenden Seitenwänden in Schlitze eintauchen, die in die Vorsprünge, insbesondere den Leisten der anderen Seitenwand eingebracht sind.This also suggests that between the Projections transverse to these supporting ribs (26) are arranged in the case of superimposed Immerse the side walls in slots that are in the Ledges, especially the ledges of others Sidewall are introduced.

Damit im heruntergeklappten Zustand die vorstehenden seitlichen Anschlagleisten der Seitenwände die Höhe nicht vergrößern, wird vorgeschlagen, daß am senkrechten Rand einer aufgerichteten Seitenwand eine senkrechte Anschlagleiste nach innen vorspringt, an deren Innenseite der senkrechte Außenrand der benachbarten Seitenwand zur Anlage gelangt und daß die Anschlagleiste gegenüber dem senkrechten Rand derart versetzt angeordnet ist, daß die Anschlagleiste zum senkrechten Rand einen Abstand bildet, der mindestens der Wandstärke der Anschlagleiste entspricht. Hierbei kann in dem von der Anschlagleiste gebildeten Abstand eine Anschlagleiste der gegenüberliegenden Seitenwand im heruntergeklappten Zustand einliegen. Auch sollte die Bodenplatte Ausnehmungen für die Anschlagleiste(n) im heruntergeklappten Zustand aufweisen.So that when folded down the above side stop strips of the side walls do not have the height enlarge, it is suggested that on the vertical edge a vertical side wall Stop bar projects inwards, on the inside the vertical outer edge of the adjacent side wall to System arrives and that the stop bar opposite the vertical edge is arranged so offset that the Stop bar forms a distance from the vertical edge, at least the wall thickness of the stop bar corresponds. This can be done from the stop bar formed distance a stop bar the opposite side wall in the folded down Condition. The bottom plate should also Recesses for the stop bar (s) in the have folded down condition.

Der Klappbehälter weist eine Bodenplatte auf mit einer Schmalseite und einer Längsseite. An allen vier Seiten ist jeweils eine Seitenwand mit ihrem unteren waagerechten Rand derart angelenkt, daß sie nach innen auf die Bodenplatte 1 klappbar ist. Hierbei werden die Seitenwände der Schmalseite zuerst nach unten geklappt und danach über diese die Seitenwände 3 der Längsseite. Beim Aufklappen des Behälters werden dann in umgekehrter Reihenfolge zuerst die Seitenwände 3 der Längsseiten hochgeklappt und danach die Seitenwände der Schmalseite. Beim Hochklappen der Seitenwände der Schmalseite gelangen die senkrechten Seitenränder dieser Seitenwände in ihrer senkrechten Stellung in die Anlage an senkrechte Anschlagleisten 4, die an den senkrechten Rändern der Seitenwände 3 nach innen vorstehen. Hierbei liegt ein senkrechter Randbereich der Seitenwand 2 an der Anschlagleiste 4 der Seitenwand 3 an.The folding container has a base plate with a Narrow side and one long side. On all four sides is a side wall with its lower one horizontal edge articulated so that it faces inwards can be folded onto the base plate 1. Here, the Side walls of the narrow side first folded down and then over this the side walls 3 of the long side. When opening the container will then be in reverse First order the side walls 3 of the long sides folded up and then the side walls of the narrow side. When folding up the side walls of the narrow side reach the vertical side edges of these side walls in their vertical position in the system on vertical Stop bars 4, which on the vertical edges of the The side walls 3 protrude inwards. Here is a vertical edge region of the side wall 2 on the Stop bar 4 of the side wall 3.

Damit die Seitenwände aneinander einen festen Halt finden, stehen an der Anschlagleiste 4 Vorsprünge 6 waagerecht vor, die in Ausnehmungen des Randbereichs der anderen Seitenwand hineinreichen und umgekehrt weist der Randbereich Vorsprünge auf, die in Ausnehmungen 7 der Anschlagleiste 4 hineinreichen. Hierbei sind die Vorsprünge und Ausnehmungen von gleicher Form und Größe beim Randbereich wie bei der Anschlagleiste 4.So that the side walls hold each other firmly there are 4 projections 6 on the stop bar horizontally in front of the recesses in the edge area of the reach into the other side wall and vice versa Edge area projections on the recesses 7 of the Reach in stop bar 4. Here are the Projections and recesses of the same shape and size for the edge area as for the stop bar 4.

Im heruntergeklappten Zustand überdecken sich die beiden Seitenwände 3a, 3b der Längsseiten zu einem Teil. Diese einander überdeckenden Bereiche 3c, 3d sind so gestaltet, daß die überdeckenden Bereiche 3c, 3d ineinandergreifen und eine Gesamthöhe H ergeben, die nicht oder nur wenig größer ist als die Dicke einer Seitenwand.When folded down, the two overlap Side walls 3a, 3b of the long sides to a part. This overlapping areas 3c, 3d are designed that the overlapping areas 3c, 3d interlock and give a total height H which is not or only a little is greater than the thickness of a side wall.

Dies wird dadurch erreicht, daß die Oberseite des überdeckenden Bereichs 3c der Seitenwand 3a abwechselnd in regelmäßigen Abständen Vorsprünge 21 und Ausnehmungen 22, insbesondere in Wellenform aufweist. Entsprechend aber umgekehrt ist die Unterseite des überdeckenden Bereichs 3d der Seitenwand 3b geformt, so daß sie sich in die Oberseite der unteren Wand 3a insbesondere formschlüssig einfügt. Hierbei können die Vorsprünge 21 und Ausnehmungen 22, insbesondere die Wellen gerundet oder eckig abgewinkelt geformt sein.This is achieved in that the top of the overlapping area 3c of the side wall 3a alternately projections 21 and recesses at regular intervals 22, in particular in wave form. Corresponding but vice versa is the bottom of the overlapping Area 3d of the side wall 3b shaped so that it is in the top of the bottom wall 3a in particular inserts positively. The projections 21 and recesses 22, in particular the waves rounded or be angularly shaped.

Damit die Anschlagleiste 4 der oberen Seitenwand 3b nicht gegen die Anschlagleiste 4 der unteren Seitenwand 3c stößt, ist die Anschlagleiste 4 der unteren Seitenwand 3c nach innen versetzt um den Betrag g angeordnet. Dieses Maß g entspricht im Ausführungsbeispiel etwa der Dicke der Wandung der Leiste 4.So that the stop bar 4 of the upper side wall 3b is not against the stop bar 4 of the lower side wall 3c bumps, the stop bar 4 of the lower side wall 3c arranged inwards by the amount g. This Dimension g corresponds approximately to the thickness in the exemplary embodiment the wall of the bar 4.

Auch weist hierzu die Bodenplatte Ausnehmungen auf, in die die Anschlagleisten 4 der Seitenwände 3 eindringen können, so daß die Seitenwände 3 genügend tief heruntergeklappt werden können.For this purpose, the base plate also has recesses in which penetrate the stop strips 4 of the side walls 3 can, so that the side walls 3 deep enough can be folded down.

Das Ausführungsbeispiel nach Figur 9-11 unterscheidet sich von dem vorangegangenen u.a. dadurch, daß die Vor-21 und Rücksprünge 22 nicht oder nur teilweise wellenförmig sind und daß der obere waagerechte Stapelrand 25 der Seitenwand eine große, insbesondere durchgehend verlaufende Auflagefläche für einen darüberstehenden zweiten Behälter bildet.The embodiment of Figure 9-11 differs different from the previous in that the pre-21 and recesses 22 not or only partially are wavy and that the upper horizontal Stacking edge 25 of the side wall a large one, in particular continuous support surface for one second container above it forms.

Die Vorsprünge 21 haben die Form von Leisten, die in taschenförmigen und/oder schlitzfömigen Rücksprüngen/Ausnehmungen 22 der anderen Seitenwand einliegen. Hierbei bilden die Vorsprünge die obere Auflagefläche für einen darüberstehenden Behälter. Zwischen den Vorsprüngen sind quer zu diesen verlaufende Stützrippen 26 angeordnet, die bei aufeinanderliegenden Seitenwänden in Schlitze eintauchen, die in die Vorsprünge, insbesondere den Leisten der anderen Seitenwand eingebracht sind. Mit 27 sind Stapelbegrenzungen gekennzeichnet.The projections 21 are in the form of strips which are formed in pocket-shaped and / or slit-shaped Recesses / recesses 22 of the other side wall inlay. The projections form the upper one Support surface for a container above. Between the projections are transverse to these Supporting ribs 26 arranged in the case of one another Immerse the side walls in slots that are in the Ledges, especially the ledges of others Sidewall are introduced. At 27 there are stacking limits featured.
