Description

Die Erfindung betrifft einen Stapelbehälter gemäß Oberbegriff des Anspruchs 1.The invention relates to a stacking container according to the preamble of claim 1.

Bekannte Stapelbehälter werden gewöhnlich zum Transport von Stückgütern benutzt. Die Stückgüter werden in den Aufnahmeraum eingelegt, und die Stapelbehälter werden aufeinander gestapelt, wobei jeweils der Aufnahmeraum eines unteren Stapelbehälters durch den nächstoberen Stapelbehälter verschlossen wird. Zum Transport werden die Stapelbehälter meist auf Paletten gestellt, und der Aufnahmeraum des jeweils obersten Stapelbehälters wird mittels eines Deckels verschlossen. Bei den aufeinander gestapelten Stapelbehältern greift der jeweils obere Stapelbehälter mit einem Absatz an seinem Boden in einen von einem Stapelrand umrandeten Bereich ein und ruht dort auf den Oberseiten der Wände. Wenn beim Transport jedoch Erschütterungen auftreten, kann dies dazu führen, dass ein Behälter an einem Ende nach oben gehoben wird. Dann ist es möglich, dass der Behälter in Richtung zu diesem Ende verrutscht. Aus diesem Grund müssen die aufeinander gestapelten Behälter beim Transport regelmäßig gesichert werden, was meistens dadurch geschieht, dass ein oder mehrere Kunststoffbänder um den Behälterstapel sowie die den Behälterstapel tragende Palette geschlungen wird bzw. werden. Zusätzlich werden die Paletten auf einer Ladefläche meist mittels Spanngurten fixiert. Dies ist aufwendig. Aus der US 5,060,819 B ist ein Stapelbehälter der eingangs genannten Art bekannt, von dessen Wänden an deren Wandoberseiten nach oben zähne vorstehen, die beim Stapeln in Ausnehmungen an der Unterseite des nächstoberen Behälters eingreifen. Diese Anordnung ist jedoch wenig stabil und erfordert ein genaues Aufsetzen der Behälter auf die Wandoberseiten des jeweils nächstunteren Behälters.Known stacking containers are usually used for the transport of piece goods. The piece goods are placed in the receiving space, and the stack containers are stacked on each other, each of the receiving space of a lower stack container is closed by the next upper stack container. For transport, the stacking containers are usually placed on pallets, and the receiving space of the topmost stacking container is closed by means of a lid. In the stacked stacking containers, the respective upper stacking container engages with a shoulder at its bottom in an area bordered by a stacking edge and rests there on the upper sides of the walls. If, however, vibrations occur during transport, this may result in a container being lifted up at one end. Then it is possible that the container will slip towards this end. For this reason, the stacked containers must be regularly secured during transport, which usually happens by one or more plastic bands are wrapped around the container stack and the container stack-carrying pallet or are. In addition, the pallets are usually fixed on a cargo bed by means of straps. This is expensive. From the US 5,060,819 B a stacking container of the type mentioned is known, projecting from the walls of the wall tops up teeth, which engage in the stacking in recesses on the underside of the next upper container. This arrangement However, it is less stable and requires a precise placement of the container on the wall tops of the next lower container.

Es ist daher Aufgabe der Erfindung, einen Stapelbehälter der eingangs genannten Art derart weiterzubilden, dass seine Handhabung vereinfacht wird.It is therefore an object of the invention to develop a stacking container of the type mentioned in such a way that its handling is simplified.

Diese Aufgabe wird erfindungsgemäß durch einen Stapelbehälter mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.This object is achieved by a stack container with the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

Der Erfindung liegt der Gedanke zugrunde, dass die Zähne eines erfindungsgemäßen Stapelbehälters in die Ausnehmungen an der Unterseite des Bodens eines weiteren, auf ihn gestapelten, baugleichen Stapelbehälters eingreifen und dadurch eine Verzahnung der aufeinander gestapelten Stapelbehälter entsteht. Diese bewirkt zusammen mit dem umlaufenden Stapelrand eine stabile Verbindung zwischen den aufeinander gestapelten Behältern. Wird der obere Stapelbehälter durch Erschütterungen beim Transport an einem seiner Enden angehoben, so kann er nicht ohne weiteres gegenüber dem unteren Stapelbehälter verrutschen, da an seinem anderen Ende die Zähne des unteren Stapelbehälters noch in Eingriff mit den Ausnehmungen des oberen Stapelbehälters sind. Der umlaufende Stapelrand hemmt nicht nur das Verrutschen zusätzlich, er verleiht den vorzugsweise einstückig mit ihm verbundenen Zähnen zudem eine höhere Stabilität und verhindert dazu ein Eindringen von Staub oder Feuchtigkeit zwischen den Zähnen. Durch diese erfindungsgemäße Maßnahme werden in den meisten Fällen die zur Sicherung verwendeten Kunststoffbänder und meist auch die Spanngurte überflüssig. Zweckmäßig stehen die Zähne aus den Oberseiten aller Wände hervor, so dass ein Verrutschen in beiden horizontalen Raumrichtungen erschwert wird.The invention is based on the idea that the teeth of a stack container according to the invention in the recesses on the underside of the bottom of another, stacked on him, identical stack container engage and thereby a toothing of the stacked stack container is formed. This, together with the peripheral stacking edge, creates a stable connection between the stacked containers. If the upper stack container is lifted by vibrations during transport at one of its ends, it can not readily slip relative to the lower stack container, since at its other end the teeth of the lower stack container are still in engagement with the recesses of the upper stack container. The peripheral stack edge not only inhibits the slippage in addition, it also gives the preferably integrally connected with him teeth a higher stability and prevents the penetration of dust or moisture between the teeth. By this measure, the plastic straps used for securing and usually also the straps are superfluous in most cases. The teeth expediently protrude from the upper sides of all walls, so that slipping in both horizontal spatial directions is made more difficult.

Vorteilhaft fluchten die dem Aufnahmeraum abgewandten Außenflächen des Stapelrands mit den Außenflächen der Wände, so dass der Stapelbehälter eine glatte Außenfläche aufweist. Zudem wird bevorzugt, dass sich der Stapelrand bis zur gleichen Höhe über den Wandoberseiten erstreckt wie die Zähne, so dass die Dichtfunktion verbessert wird. Zudem weist der Stapelrand zweckmäßig eine umlaufende Fase auf, die eine ausgehend von seinen Außenflächen in Richtung zum Aufnahmeraum ansteigende umlaufende Fläche bildet. Auch diese Maßnahme verbessert die Dichtwirkung, indem an der Außenfläche eines Behälterstapels ablaufende Flüssigkeit wie Regenwasser durch die Fase nach außen abgeleitet wird, wobei die Fase wie eine Tropfkante wirkt.The outer surfaces of the stack edge facing away from the receiving space advantageously align with the outer surfaces of the walls, so that the stack container has a smooth outer surface. In addition, it is preferred that the stack edge extends to the same height above the top of the wall as the teeth, so that the Density function is improved. In addition, the stack edge expediently has a circumferential chamfer, which forms a circumferential surface rising from its outer surfaces in the direction of the receiving space. This measure also improves the sealing effect by discharging liquid draining from the outer surface of a container stack, such as rainwater, through the chamfer to the outside, the chamfer acting like a drip edge.

Zweckmäßig sind die Ausnehmungen jeweils senkrecht unter einem der Zähne angeordnet. Damit befindet sich in vertikaler Richtung exakt unter jedem Zahn eine Ausnehmung, die so dimensioniert ist, dass sie für die Aufnahme eines solchen Zahns geeignet ist. Die Stapel behälter können dann mit zueinander fluchtenden Außenwänden übereinander gestapelt werden.Suitably, the recesses are each arranged vertically below one of the teeth. This is located in the vertical direction just below each tooth has a recess which is dimensioned so that it is suitable for receiving such a tooth. The stack containers can then be stacked with aligned outer walls one above the other.

Es wird bevorzugt, dass die in Längsrichtung der Wandoberseiten gemessene Länge jedes der Zähne etwa der Länge der unter ihm angeordneten Ausnehmung entspricht. Die Zähne sind dann ohne oder mit nur wenig Spiel in den Ausnehmungen aufgenommen. Zweckmäßig ist jeder der Zähne in seiner Form komplementär zur unter ihm angeordneten Ausnehmung. Des weiteren wird bevorzugt, dass die Zähne an zumindest einer der Wände nicht alle dieselbe Länge aufweisen. Vorzugsweise trifft dies auf jede Wand zu, so dass an jeder Wand mindestens ein Zahn angeordnet ist, dessen Länge sich von der Länge der anderen, an dieser Wand angeordneten Zähne unterscheidet. Durch diese Maßnahme wird sichergestellt, dass die Stapel behälter stets in der richtigen Position in Bezug aufeinander, nämlich mit zumindest im wesentlichen zueinander fluchtenden Außenflächen der Wände, aufeinander gestapelt werden, da sonst ein Ineinandergreifen der Zähne und Ausnehmungen nicht möglich ist. Zudem ist es möglich, dass die Zähne in der Mitte der Wände eine größere Länge aufweisen als an den an die jeweils benachbarten Wände angrenzenden Wandenden und/oder dass die Zähne und die Ausnehmungen so dimensioniert sind, dass die Zähne mit Spiel in den Ausnehmungen eines baugleichen Stapelbehälters aufnehmbar sind und dass das Spiel in der Mitte der Wände größer ist als an den an die jeweils benachbarten Wände angrenzenden Wandenden. Diese Maßnahme erhöht die Fertigungstoleranzen, während ein Einpassen der Zähne in der Mitte der Wände in die entsprechenden Ausnehmungen mit wenig Spiel die Behälter in ihrer Position zueinander schon gut festlegt.It is preferred that the length of each of the teeth measured in the longitudinal direction of the wall tops corresponds approximately to the length of the recess arranged below it. The teeth are then added without or with little play in the recesses. Suitably, each of the teeth in its shape is complementary to the recess arranged below it. It is further preferred that the teeth on at least one of the walls are not all the same length. Preferably, this applies to each wall, so that at least one tooth is arranged on each wall, the length of which differs from the length of the other, arranged on this wall teeth. This measure ensures that the stack container always in the correct position with respect to each other, namely with at least substantially aligned outer surfaces of the walls, stacked on each other, otherwise meshing of the teeth and recesses is not possible. In addition, it is possible that the teeth have a greater length in the middle of the walls than at the wall ends adjoining the respective adjacent walls and / or that the teeth and the recesses are dimensioned so that the teeth with play in the recesses of a similar Stacking container can be accommodated and that the game in the middle of the walls is greater than at the adjacent to the respective adjacent walls wall ends. This measure increases the Manufacturing tolerances, while fitting the teeth in the middle of the walls in the corresponding recesses with little play the container in position to each other already good.

Zweckmäßig sind die Ausnehmungen zur Außenkontur des Bodens hin randoffen. Sie werden vorzugsweise von einem umlaufenden Absatz umrandet, der zweckmäßig in seinen Abmessungen dem Stapelrand komplementär ist und auf dem Stapelrand eines nächstunteren baugleichen Stapelbehälters aufliegt.Suitably, the recesses are open to the outer contour of the ground. They are preferably surrounded by a circumferential paragraph, which is useful in its dimensions complementary to the stacking edge and rests on the stacking edge of a next lower identical stacking container.

Der erfindungsgemäße Stapelbehälter ist zweckmäßig einstückig ausgebildet mit vorzugsweise starr an den Boden angeformten und starr miteinander verbundenen Wänden. Als Material kommt insbesondere ein Partikelschaumstoff in Frage, wobei expandiertes Polypropylen (EPP) und expandiertes Polyurethan (EPU) bevorzugt werden.The stack container according to the invention is expediently integrally formed with preferably rigidly molded to the ground and rigidly interconnected walls. The material used is in particular a particle foam, with expanded polypropylene (EPP) and expanded polyurethane (EPU) being preferred.

Vorteilhaft ist zwischen dem Boden und den Wänden und/oder zwischen jeweils zwei aneinander angrenzenden Wänden an der dem Aufnahmeraum zugewandten Seite jeweils eine Fase angeordnet. Die Fase füllt den Winkel zwischen dem Boden und der betreffenden Wand bzw. den Winkel zwischen zwei Wänden aus und stabilisiert dadurch den Stapelbehälter in diesem Bereich. Dies ist insbesondere relevant, da der Verbindungsbereich zwischen dem Boden und den Wänden durch die außenseitigen Ausnehmungen geschwächt ist. Bei auf die Stapelbehälter wirkender hoher Auflast wirken die Fasen zwischen den aneinander angrenzenden Wänden einem Aufdehnen des unteren Stapelbehälters entgegen, das dazu führen kann, dass der obere Stapelbehälter ein Stück weit in den unteren einsinkt.Advantageously, a chamfer is arranged in each case between the floor and the walls and / or between in each case two adjoining walls on the side facing the receiving space. The chamfer fills the angle between the floor and the respective wall or the angle between two walls and thereby stabilizes the stacking container in this area. This is particularly relevant because the connection area between the floor and the walls is weakened by the outside recesses. When acting on the stack container high ballast, the chamfers between the adjacent walls counteract an expansion of the lower stack container, which can cause the upper stack container sinks a little way into the lower.

Im Folgenden wird die Erfindung anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels näher erläutert. Es zeigen

one of the stack container according to Fig. 1a . 1b in perspective view from above and from below.

In Fig. 1a, 1b sind mehrere Stapelbehälter 10 dargestellt, die in zwei nebeneinander auf einer Palette 12 aufgesetzten Behälterstapeln 14 angeordnet sind. Im gezeigten Ausführungsbeispiel weist jeder Behälterstapel 14 drei Stapelbehälter 10a auf, welche jeweils einstückig aus einem Partikelschaumstoff hergestellt sind. Jeder der Stapelbehälter 10a weist einen Boden 16 mit im Wesentlichen rechteckigem Grundriss sowie vier sich vom Boden 16 aus nach oben erstreckende Wände 18 auf. Die Wände 18 umschließen einen nach unten durch den Boden 16 begrenzten Aufnahmeraum 20, der nach oben offen ist und an seiner Oberseite eine Öffnung 22 aufweist. Zu jedem Stapelbehälter 10 bildet der nächstobere, auf ihn aufgesetzte Stapelbehälter 10a eine Art Deckel, indem er die Öffnung 22 vollständig verschließt. Die beiden obersten Stapelbehälter 10 werden durch einen gemeinsamen Deckel 24 verschlossen.In Fig. 1a . 1b a plurality of stacking container 10 are shown, which are arranged in two side by side on a pallet 12 patched stacks of containers 14. In the exemplary embodiment shown, each container stack 14 has three stack containers 10a, which are each manufactured in one piece from a particle foam. Each of the stacking containers 10a has a bottom 16 with a substantially rectangular layout and four walls 18 extending upwardly from the bottom 16. The walls 18 enclose a downwardly bounded by the bottom 16 receiving space 20 which is open at the top and has an opening 22 at its top. For each stack container 10, the next upper, placed on it stack container 10a forms a kind of cover by the opening 22 completely closes. The two uppermost stack container 10 are closed by a common cover 24.

Aus den dem Boden 16 abgewandten Wandoberseiten 26 stehen nach oben Zähne 28 vor, zwischen denen Lücken 30 angeordnet sind. Direkt unter jedem Zahn 28, also in vertikaler Richtung gegenüber dem Zahn 28 nach unten versetzt, weist der Boden 16 an seiner Unterseite 32 jeweils eine Ausnehmung 34 auf, die komplementär zum betreffenden Zahn 28 ausgestaltet ist und in ihrer Form und Größe der Form und Größe des Zahns 28 entspricht. Insbesondere entspricht die in Längsrichtung der betreffenden Wandoberseite 26 gemessene Länge jedes Zahns 28 in etwa der Länge der zugehörigen Ausnehmung 34. Bei dem Stapelbehälter 10a gemäß dem ersten Ausführungsbeispiel sind die Zähne 28 zudem gegenüber einer durch die dem Aufnahmeraum abgewandten Außenflächen 36 der Wände 18 gebildete Außenkontur, die dem rechteckigen Grundriss des Bodens 16 entspricht, ein Stück weit nach innen in Richtung zum Aufnahmeraum 20 versetzt angeordnet. Zwischen den Zähnen 28 und der Außenkontur der Wände 18 befindet sich ein von den Wandoberseiten 26 nach oben vorstehender, rings umlaufender und an die Zähne 28 direkt angrenzender Stapelrand 38.
