Definitions
- the present disclosure relates to a container, in particular a large load carrier that can be nested or nested, with a base and side walls which widen conically and/or in steps, in particular from the base to a peripheral container edge.
- Nestable containers are known from the prior art, which have side walls that widen towards the container opening and thus allow a plurality of unfilled containers to be nested to reduce the transport volume when transported empty.
- the object of the present invention is to provide a container with a more robust construction.
- a container which has a particularly rectangular base and side walls which extend from the base to a container edge. At least one of the side walls of the container has a bumper or shock absorber on its outside, which is arranged below the container edge and preferably at a distance from it when viewed in the direction of container height and protrudes from said outside at least so far that it forms a plane between an outer edge of the bottom and an, in particular lower, outer edge of the container edge which is stretched over at least one side wall, touches or intersects. Due to such a constructive design, when the container tilts about the associated outer edge of the base, the bumper hits a flat base in front of the edge of the container.
- the bumper is hollow, in particular in the form of a hollow profile, or there is a clear width between the bumper and the outer surface of the associated side wall, which is shielded from it.
- the bumper tapers or is rounded towards the outside of the container and is structurally designed and adapted to withstand a lateral impact on the container to dissipate elastic and / or plastic deformation at least partially, ie the bumper is adapted in its structure and / or its choice of materials to energy occurring in an impact, for example, by internal friction losses.
- the at least one bumper can be arranged in the upper third of the container, viewed in the container height direction, in particular at a distance of 180 to 240 mm from the upper container edge.
- the side walls can widen out from the bottom in the direction of the container edge, in particular extending conically and/or in steps.
- the container cross-section which widens in the container height direction, enables nesting or nesting of several containers of the same construction.
- a bumper is particularly advantageous in such nestable containers, since the edge is particularly exposed due to the conical shape of the walls.
- the bumper can be designed so that it does not protrude further in a direction parallel to the floor than the outer edge of the container edge of the container side protected/shielded by it, in order not to increase the external dimensions of the container.
- the bumper after terminate flush with said outer edge of the container rim on the outside or be arranged flush with this in the container height direction.
- the container can have four side walls and four bumpers can be arranged in each corner area of the container.
- the bumpers can preferably be arranged on two opposite side walls of the container. It is advisable, for example in the case of containers with an essentially rectangular base, to provide bumpers on the longer side walls, since the containers tend to tip over the longer bottom edge. In the case of large load carriers, there is often a predetermined engagement direction or engagement sides for forklifts and the like. In this case, it is advantageous to arrange the bumpers on side walls remote from the engagement sides, since a stack of nested containers will tend to tip away from the forklift.
- the bumper can have a predetermined impact absorption or crumple section which is designed to dissipate impact energy in the event of an impact with elastic and/or plastic deformation.
- a predetermined impact absorption or crumple section which is designed to dissipate impact energy in the event of an impact with elastic and/or plastic deformation.
- the impact absorbing portion may be a folded portion of the bumper.
- the impact absorption section can be a predetermined breaking point which is introduced in a targeted manner and which dampens the force of the impact.
- the bumper can have an elastomer section for better shock absorption.
- the bumper can be suspended from the container via an elastic spring section, for example an integral plastic leaf spring section, and can thus be arranged on the container in a spring-biased manner so that it can move relative to the container side wall.
- an elastic spring section for example an integral plastic leaf spring section
- the bumper tapers towards the outside of the container or in the direction away from the container. In this way, impact forces can be absorbed at a predetermined comparatively small-area section of the bumper and distributed over a larger area of the container.
- the bumper can have a projection on the outside of the container for the defined application of impact forces, which protrudes obliquely away from the container and downwards (towards the ground) from the bumper.
- the edge of the container can be designed to protrude towards the outside of the container. More preferably, the projecting edge of the container can project at least on two opposite sides by more than 10 mm, so that said projecting edge is adapted to be engaged by a fork of a lift truck or other industrial truck from one side.
- the container can be a large load carrier with a pallet-shaped base part that is adapted for engaging a fork of a lift truck or other industrial truck.
- large forces act when stacks of containers placed on top of one another tip over, so that a bumper according to the invention is particularly advantageous.
- the bumper can be designed as a bumper bar arranged on the outside of the associated side wall.
- the container can be made of plastic, in particular in an injection molding or rotomoulding process.
- the container can be made of one piece of material and the bumper can be molded integrally onto it.
- Figures 1A and 1B show a perspective view of a container 1 according to a preferred embodiment of the invention.
- the container 1 shown is a large load carrier made of plastic with a pallet-shaped base 2 with recesses 3 for engaging the fork of a lifting truck and four side walls 4, 6, 8, 10.
- the container 1 shown is designed as a nestable container 1, ie the four side walls 4, 6, 8, 10 widen conically towards the container opening in order to enable identical containers 1 to be nested (see e.g. Figure 2A ).
- the container 1 shown is a so-called rotary stacking container, which can either be stacked or nested with an identical container, depending on the relative rotation of the two identical containers to one another.
- the container 1 shown has a cantilever defining its container opening and is structurally reinforced with a circumferential rim of ribs
- Container rim 12 The ribbed structure of container rim 12 forms recessed areas (not described in more detail here) that allow one or more containers 1 to be lifted out of a stack of nested containers 1 for separation using a fork lift truck. Precisely in the case of such separating operations with fork lift trucks, it often happens that stacks of containers 1 placed one inside the other are knocked over.
- the container 1 of Figures 1A and 1B also has horizontal or floor-parallel projections or ribs 13 in its corner areas, which are arranged lower than the surrounding rib rings of the container edge 12 and serve as a stop to limit the nest depth when stacking several identical containers 1.
- the Figures 2A, 2B and 2C illustrate the behavior of a stack of nested large load carriers 1.1' when tipping over. Applicant has found that due to inertia and play between the individual nested containers 1, the lower edge of the projecting container edge 12' of the bottommost container 1' of the stack often forms the first point of impact of such a stack of containers. As a rule, this is not designed for such loads, as a result of which the container edge 12' breaks and the container 1' becomes unusable.
- Figure 2B As can be seen, the containers 1 arranged further up in the stack tend to hit the ground with their container edge 12 rather flat when tipping over.
- Figure 2C shows an end position in which the stack comes to rest on the container edges 12 of the container 1.
- the rim 12 of the bottommost container 1 of a tipping stack of nested containers 1 receives a disproportionate portion of the impact force and the precise impact point of each container 1 varies with its position in the container stack. As a result, it is difficult to design the container rim 12 for this load.
- the container 1 according to the preferred exemplary embodiment of the invention has an impact absorbing structure or a bumper 14 .
- the bumper 14' is designed to project below the container edge 12' and far enough out of the side wall that when a stack of nested containers 1 tips over, the bumper 14' of the lowest container 1' hits the ground in front of its container edge 12A .
- the container 1 according to the preferred exemplary embodiment has four such bumpers 14 which are each arranged in corner regions and essentially shield or protect two opposite side walls 4, 6 of the container 1 project this (cf. Figure 1A ).
- the bumper 14 is designed as a shock absorbing structure which is spaced from the edge 12 of the container towards the underside of the container and protrudes in profile over the side wall 4, 6.
- the bumper protrudes so far from the associated outside of the container that it forms an imaginary plane E that spans between the lower outer edge 24, 26, 28, 30 of the projecting container edge 12 and the outer edge 16, 18, 20, 22 of the base 2 is, pierces.
- the bumper 14 protrudes so far from the outside of the associated side wall 4, 6, 8, 10 that it protrudes beyond the imaginary plane E and thus if it tips over (with the outer edge 16, 18, 20, 22 of the floor 2 as the instantaneous pole) in front of the lower outer edge 24, 26, 28, 30 of the projecting container edge 12 hits the ground.
- the bumper 14 is spaced downwards from the container edge 12 in the container height direction and projects so far in a direction parallel to the ground that it ends flush with a projection A of the outer surface of the container edge 12 .
- this fulfills the purpose that the bumper does not unnecessarily increase the external dimensions of the container 1 and, on the other hand, the outer surface of the container edge 12 and the bumper 14 can both serve as support points in a stack of containers that has fallen over (see also Figure 2C ).
- bumpers 14 in accordance with the present invention will now be discussed. What all of these embodiments have in common is that their overall structure or predetermined impact absorption sections 32 are designed to at least partially absorb or dissipate impacts. Mechanisms for such dissipation of impact energy are mainly internal friction losses during elastic deformation and/or during plastic deformation of components.
- the in the Figures 3 and 4 The basic structure of the bumper 14 shown is designed as a hollow profile and is arranged in each of the corner areas of the container 1 .
- the said hollow profile shape encloses a hollow space or a clear space R between the side wall and the bumper 14 .
- the bumper 14 in the form of a hollow profile is integrally formed on the container 1 and exhibits elasticity and a defined spring deflection/a defined crumple zone for absorbing impact forces due to its overall structure or due to the clear space R enclosed towards the wall.
- the hollow profile shape of the bumper 14 forms a defined impact section 15 at its end (seen from the shielded side wall 4) on the outside of the container, in this case a flattened end section.
- the structure of the bumper 14 (the hollow profile) widens in the direction of the container or in the direction of a central plane M of the container. This has the advantage that impact forces at the impact section 15 can be introduced into the bumper 14 in a defined manner and then distributed over a larger area and introduced into the container 1 .
- the widening hollow profile structure supports a defined elastic deformation of the bumper 14.
- the bumper 14 in the form of a hollow profile is molded onto the container 1 in such a way that the hollow profile is open in the direction of the side wall 8 , 10 adjoining the shielded side wall 4 , 6 . This enables good demouldability during manufacture in a plastic casting process.
- a lower section of the bumper 14 (or its hollow profile shape) running essentially horizontally or parallel to the ground is formed by the rib 13, which also serves to limit the nest depth.
- FIG 5 1 shows a detailed view of a bumper 14 in the form of a hollow profile according to a second exemplary embodiment, which is similar in its form and function to the bumper 14 according to the first exemplary embodiment.
- the main distinguishing feature of the bumper 14 according to the second embodiment from the first embodiment is the rounded or essentially semicircular hollow profile shaped impact section 15.
- the semicircular profile shape generates a higher impact point in the event of a tipping over and thus an advantageous introduction of force into the hollow profile structure of the bumper 14, which widens in the direction of the container center plane M.
- the bumper 14 shown according to a third exemplary embodiment of the invention has a round/rounded impact section 15 like the bumper 14 according to the second exemplary embodiment.
- the bumper 14 has on the lower half of its semicircular impact section 15 a projection 34 pointing obliquely away from the interior of the container and pointing downwards for a defined introduction of force into the bumper 14 .
- the semi-circular abutting section 15 is designed with a reduced material thickness above the projection 34 in order to provide a defined predetermined breaking point 35 in this area.
- FIG. 7 shows a fourth embodiment of a bumper 14 according to the invention.
- This has an impact absorption section 38 in the form of a folded section 38 .
- the folded structure enables a defined deformation with increased energy dissipation per compressed section.
- the folded section 38 is in the horizontally extending section or the rib 13 of the bumper 14 and in the form of a hollow profile arranged adjacent to the impact section 15 in order to absorb impact forces occurring on impact as directly as possible.
- FIG 8 shows a fifth preferred embodiment of a bumper 14, which is manufactured in a 2-component injection molding process.
- the impact section 15 of the bumper 14, which projects away from the interior of the container is coated with an elastomer section 40, which cushions the forces occurring on impact.
- an elastomer pad 40 is molded onto the bumper 14 on the outside of the container for better shock absorption.
- the impact portion 15 per se forms the impact absorbing portion 32 .

Description
Die vorliegende Offenbarung betrifft einen Behälter, insbesondere einen nestbaren bzw. ineinandersetzbaren Großladungsträger, mit einem Boden und Seitenwänden, die sich insbesondere vom Boden aus zu einem umlaufenden Behälterrand konisch und/oder in Stufen erweitern.The present disclosure relates to a container, in particular a large load carrier that can be nested or nested, with a base and side walls which widen conically and/or in steps, in particular from the base to a peripheral container edge.
Aus dem Stand der Technik sind nestbare Behälter bekannt, die sich zur Behälteröffnung hin aufweitende Seitenwände aufweisen und so ein Ineinandersetzen mehrerer unbefüllter Behälter zur Verringerung des Transportvolumens beim Leertransport ermöglichen.Nestable containers are known from the prior art, which have side walls that widen towards the container opening and thus allow a plurality of unfilled containers to be nested to reduce the transport volume when transported empty.
Untersuchungen der Anmelderin zur Umkipp-Kinematik eines Stapels derart ineinander gesetzter Behälter haben gezeigt, dass beim Umkippen auf einen ebenen Boden wegen des trägheitsbedingten späteren Auftreffens der weiter oben im Stapel angeordneten Behälter und des sich nach oben hin erweiternden Behälterquerschnitts der obere Rand des untersten Behälters des Stapels als erstes auf den Boden prallt. Gerade bei Großladungsträgern, die mit Gabelstaplern oder vergleichbaren Flurförderzeugen gehandhabt werden, kommt es vergleichsweise häufig zu einem solchen Umkippen eines Behälterstapels. Insbesondere beim Bilden von Stapeln und bei der Vereinzelung von Behältern aus einem solchen Stapel kommt es häufig dazu, dass mit den Gabelzinken nicht die vorgesehenen Eingriffsausnehmungen getroffen werden und der Stapel umgestoßen wird. Vor allem bei hohen Stapeln von solch großen Behältern treten bei einem Umkippen sehr große Aufprallkräfte auf, die dann auf einen einzigen Behälterrand einwirken, was häufig zum Bruch der Behälterrandung des besagten untersten Behälters führt. Ein konischer Behälter mit gebrochenem Behälterrand ist aufgrund der tragenden Wirkung des Randes in der Regel unbrauchbar und muss aussortiert werden.Investigations by the applicant into the tipping kinematics of a stack of such nested containers have shown that when tipping over onto a level floor, the upper edge of the lowermost container of the stack hits the ground first. Especially in the case of large load carriers that are handled with forklifts or comparable industrial trucks, such a tipping over of a stack of containers occurs comparatively frequently. In particular when forming stacks and when separating containers from such a stack, it often happens that the fork tines do not hit the intended engagement recesses and the stack is knocked over. Especially with high stacks of such large containers, very large impact forces occur when they tip over a single container rim, often resulting in rupture of the container rim of said lowermost container. A conical container with a broken rim is usually unusable due to the load-bearing effect of the rim and must be sorted out.
Der relevante vorbekannte Stand der Technik ergibt sich aus der
Aufgabe der vorliegenden Erfindung ist es vor diesem Hintergrund, einen Behälter mit robusterer Konstruktion bereitzustellen.Against this background, the object of the present invention is to provide a container with a more robust construction.
Diese Aufgabe wird durch die Merkmale des unabhängigen Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.This object is solved by the features of
Erfindungsgemäß ist ein Behälter vorgesehen, der einen, insbesondere rechteckförmigen, Boden und Seitenwände, die sich vom Boden aus zu einem Behälterrand erstrecken aufweist. Zumindest eine der Seitenwände des Behälters weist an ihrer Außenseite einen Stoßfänger bzw. -dämpfer auf, der in Behälterhöhenrichtung betrachtet unterhalb des Behälterrandes und vorzugsweise von diesem beabstandet angeordnet ist und von besagter Außenseite zumindest so weit vorspringt, dass er eine Ebene, die zwischen einer Außenkante des Bodens und einer, insbesondere unteren, Außenkante des Behälterrandes der zumindest einen Seitenwand aufgespannt wird, tangiert oder schneidet. Durch eine solche konstruktive Auslegung trifft bei einer Kippbewegung des Behälters um die zugehörigen Außenkante des Bodens der Stoßfänger vor dem Behälterrand auf einem ebenen Boden auf. Zudem ist der Stoßfänger hohl, insbesondere hohlprofilförmig, ausgebildet oder ist zwischen dem Stoßfänger und der Außenfläche der dazugehörigen, von diesem abgeschirmten Seitenwand eine lichte Weite ausgebildet. Ferner ist der Stoßfänger ist zum Behälteräußeren hin spitz zulaufend oder abgerundet ausgebildet und konstruktiv dazu ausgelegt und angepasst, einen seitlich auf den Behälter wirkenden Stoß unter elastischer und/oder plastischer Verformung zumindest teilweise zu dissipieren, d.h. der Stoßfänger ist in seiner Struktur und/oder seiner Materialauswahl dazu angepasst bei einem Aufprall auftretende Energien bspw. durch innere Reibungsverluste aufzunehmen.According to the invention, a container is provided which has a particularly rectangular base and side walls which extend from the base to a container edge. At least one of the side walls of the container has a bumper or shock absorber on its outside, which is arranged below the container edge and preferably at a distance from it when viewed in the direction of container height and protrudes from said outside at least so far that it forms a plane between an outer edge of the bottom and an, in particular lower, outer edge of the container edge which is stretched over at least one side wall, touches or intersects. Due to such a constructive design, when the container tilts about the associated outer edge of the base, the bumper hits a flat base in front of the edge of the container. In addition, the bumper is hollow, in particular in the form of a hollow profile, or there is a clear width between the bumper and the outer surface of the associated side wall, which is shielded from it. Furthermore, the bumper tapers or is rounded towards the outside of the container and is structurally designed and adapted to withstand a lateral impact on the container To dissipate elastic and / or plastic deformation at least partially, ie the bumper is adapted in its structure and / or its choice of materials to energy occurring in an impact, for example, by internal friction losses.
Das Vorsehen eines Hohlraums bzw. eines lichten Raumes zwischen Stoßfänger und der durch diesen abgeschirmten Seitenwand ermöglicht es, einen bestimmten Verformungsweg bzw. eine Knautschzone zu definieren, auf welchem der Stoßfänger sich verformen und somit Aufprallenergie dissipieren kann.The provision of a hollow space or a clear space between the bumper and the side wall shielded by it makes it possible to define a specific deformation path or a crumple zone on which the bumper can deform and thus dissipate impact energy.
Gemäß einem weiter bevorzugten Ausführungsbeispiel der Erfindung kann der zumindest eine Stoßfänger in Behälterhöhenrichtung gesehen im oberen Drittel des Behälters angeordnet sein, insbesondere mit einem Abstand von 180 bis 240 mm zum oberen Behälterrand.According to a further preferred exemplary embodiment of the invention, the at least one bumper can be arranged in the upper third of the container, viewed in the container height direction, in particular at a distance of 180 to 240 mm from the upper container edge.
Gemäß einem bevorzugten Ausführungsbeispiel der Erfindung können die Seitenwände sich vom Boden aus in Richtung Behälterrand, insbesondere konisch und/oder in Stufen, aufweitend erstrecken. Der sich in Behälterhöhenrichtung erweiternde Behälterquerschnitt ermöglicht ein Nesten bzw. Ineinanderschachteln mehrerer baugleicher Behälter. Bei solchen nestbaren Behältern ist ein Stoßfänger besonders von Vorteil, da der Rand aufgrund der konischen Form der Wände besonders exponiert ist.According to a preferred exemplary embodiment of the invention, the side walls can widen out from the bottom in the direction of the container edge, in particular extending conically and/or in steps. The container cross-section, which widens in the container height direction, enables nesting or nesting of several containers of the same construction. A bumper is particularly advantageous in such nestable containers, since the edge is particularly exposed due to the conical shape of the walls.
Gemäß einer bevorzugten Ausführungsform kann der Stoßfänger so ausgelegt sein, dass er in bodenparalleler Richtung nicht weiter vorspringt als die Außenkante des Behälterrandes der durch ihn geschützten/abgeschirmten Behälterseite, um die Außenmaße des Behälters nicht zu vergrößern. Bevorzugt kann der Stoßfänger nach außen hin bündig mit besagter Außenkante des Behälterrandes abschließen bzw. in Behälterhöhenrichtung fluchtend mit dieser angeordnet sein.According to a preferred embodiment, the bumper can be designed so that it does not protrude further in a direction parallel to the floor than the outer edge of the container edge of the container side protected/shielded by it, in order not to increase the external dimensions of the container. Preferably, the bumper after terminate flush with said outer edge of the container rim on the outside or be arranged flush with this in the container height direction.
Gemäß einer bevorzugten Ausführungsform kann der Behälter vier Seitenwände aufweisen und vier Stoßfänger können jeweils in Eckbereichen des Behälters angeordnet sein. Auf diese Weise können Aufprallkräfte gut in die ohnehin verstärkten Eckbereiche eines Behälters eingeleitet werden. Bevorzugt können die Stoßfänger an zwei einander gegenüberliegenden Seitenwänden des Behälters angeordnet sein. Es bietet sich an, bspw. bei Behältern mit im Wesentlichen rechteckförmiger Grundfläche, Stoßfänger jeweils an den längeren Seitenwänden vorzusehen, da die Behälter eher über die längere Bodenkante kippen. Bei Großladungsträgern gibt es häufig eine vorbestimmte Eingriffsrichtung bzw. Eingriffsseiten für Gabelstapler und dergleichen. In diesem Fall ist es von Vorteil, die Stoßfänger jeweils an von den Eingriffsseiten abgewandten Seitenwänden anzuordnen, da ein Stapel genesteter Behälter meist vom Gabelstapler weg kippen wird.According to a preferred embodiment, the container can have four side walls and four bumpers can be arranged in each corner area of the container. In this way, impact forces can be introduced well into the already reinforced corner areas of a container. The bumpers can preferably be arranged on two opposite side walls of the container. It is advisable, for example in the case of containers with an essentially rectangular base, to provide bumpers on the longer side walls, since the containers tend to tip over the longer bottom edge. In the case of large load carriers, there is often a predetermined engagement direction or engagement sides for forklifts and the like. In this case, it is advantageous to arrange the bumpers on side walls remote from the engagement sides, since a stack of nested containers will tend to tip away from the forklift.
Gemäß einem weiter bevorzugten Aspekt der Erfindung kann der Stoßfänger einen vorbestimmten Prallabsorbtions- oder Knautschabschnitt aufweisen, der dazu ausgebildet ist, Stoßenergie bei einem Aufprall unter elastischer und/oder plastischer Verformung zu dissipieren. Es sind verschiedene Ausführungsformen solcher Prallabsorptionsabschnitte denkbar. Gemäß einem bevorzugten Ausführungsbeispiel kann der Prallabsorptionsabschnitt ein gefalteter Abschnitt des Stoßfängers sein. Gemäß einem weiteren Ausführungsbeispiel kann der Prallabsorptionsabschnitt eine gezielt eingebrachte Sollbruchstelle sein, die die Aufprallwucht dämpft. Gemäß einem weiteren Ausführungsbeispiel kann der Stoßfänger einen Elastomerabschnitt zur besseren Stoßdämpfung aufweisen.According to a further preferred aspect of the invention, the bumper can have a predetermined impact absorption or crumple section which is designed to dissipate impact energy in the event of an impact with elastic and/or plastic deformation. Various embodiments of such impact absorption sections are conceivable. According to a preferred embodiment, the impact absorbing portion may be a folded portion of the bumper. According to a further exemplary embodiment, the impact absorption section can be a predetermined breaking point which is introduced in a targeted manner and which dampens the force of the impact. According to a further exemplary embodiment, the bumper can have an elastomer section for better shock absorption.
Gemäß einer bevorzugten Ausführungsform der Erfindung kann der Stoßfänger über einen elastischen Federabschnitt, bspw. einen integralen Kunststoff-Blattfederabschnitt, am Behälter aufgehängt sein und somit federvorgespannt relativbeweglich zur Behälterseitenwand am Behälter angeordnet sein.According to a preferred embodiment of the invention, the bumper can be suspended from the container via an elastic spring section, for example an integral plastic leaf spring section, and can thus be arranged on the container in a spring-biased manner so that it can move relative to the container side wall.
Der Stoßfänger verjüngt sich zum Behälteräußeren hin bzw. in Richtung vom Behälter weg. Auf diese Weise können Aufprallkräfte an einem vorbestimmten vergleichsweise kleinflächigen Abschnitt des Stoßfängers aufgenommen und in eine größere Fläche des Behälters verteilt werden.The bumper tapers towards the outside of the container or in the direction away from the container. In this way, impact forces can be absorbed at a predetermined comparatively small-area section of the bumper and distributed over a larger area of the container.
Gemäß einer bevorzugten Ausführungsform der Erfindung kann der Stoßfänger behälteraußenseitig einen Vorsprung zur definierten Krafteinleitung von Aufprallkräften aufweisen, der in Richtung schräg vom Behälter weg und nach unten (in Richtung hin zum Boden) vom Stoßfänger vorspringt.According to a preferred embodiment of the invention, the bumper can have a projection on the outside of the container for the defined application of impact forces, which protrudes obliquely away from the container and downwards (towards the ground) from the bumper.
Gemäß einem weiter bevorzugten Aspekt der Erfindung kann der Behälterrand zum Behälteräußeren hin vorkragend ausgebildet sein. Weiter bevorzugt kann der vorkragende Behälterrand zumindest an zwei gegenüberliegenden Seiten um mehr als 10 mm vorkragen, sodass besagter vorkragender Rand von einer Seite für einen Eingriff einer Gabel eines Hubstablers oder anderen Flurförderzeugs angepasst ist.According to a further preferred aspect of the invention, the edge of the container can be designed to protrude towards the outside of the container. More preferably, the projecting edge of the container can project at least on two opposite sides by more than 10 mm, so that said projecting edge is adapted to be engaged by a fork of a lift truck or other industrial truck from one side.
Besonders bevorzugt kann der Behälter ein Großladungsträger mit einem palettenförmigen, für einen Eingriff einer Gabel eines Hubstablers oder anderen Flurförderzeugs angepassten Bodenteil sein. In solchen Behältern wirken große Kräfte beim Umkippen von Stapeln eineinandergesetzter Behälter, sodass ein erfindungsgemäßer Stoßfänger von besonderem Vorteil ist.Particularly preferably, the container can be a large load carrier with a pallet-shaped base part that is adapted for engaging a fork of a lift truck or other industrial truck. In such containers, large forces act when stacks of containers placed on top of one another tip over, so that a bumper according to the invention is particularly advantageous.
Gemäß einer alternativen Ausführungsform kann der Stoßfänger als ein außenseitig der zugehörigen Seitenwand angeordneter Stoßbügel ausgebildet sein.According to an alternative embodiment, the bumper can be designed as a bumper bar arranged on the outside of the associated side wall.
Gemäß einem weiter bevorzugten Aspekt der Erfindung kann der Behälter aus Kunststoff, insbesondere in einem Spritzguss- oder Rotomouldingverfahren, gefertigt sein. Besonders bevorzugt kann der Behälter stoffeinstückig gefertigt und der Stoßfänger integral an diesem angefromt sein.According to a further preferred aspect of the invention, the container can be made of plastic, in particular in an injection molding or rotomoulding process. Particularly preferably, the container can be made of one piece of material and the bumper can be molded integrally onto it.
