Definitions
- the invention relates to a container with a number of side walls.
- the container side wall acts as a stabilizer.
- stabilizing agents such as so-called “sandwich structures”
- Sandwich structures usually comprise two rigid cover layers, between which is a lighter core material, for example paper honeycomb, light wood, polyurethane, polystyrene or the like.
- cover layers are placed in a mold and held from the outside by means of printing plates in the desired spacing or in the form and then filled, for example, with polyurethane foam.
- the cover layers with the core material can be stretched into a mold and pressed, glued or welded.
- This production is relatively laborious and costly and requires additional forms and machines, which, for example, must be adapted to the form of the sandwich structure or forms of the starting materials, which in turn makes the production of the sandwich structures more expensive.
- Container for contents and corresponding container side walls are also well known.
- An example of such containers are tons or barrels, cardboard boxes or “intermediate bulk container “(" IBC "), which are rigid and often rigid (“ intermediate bulk container “,” RIBC ”) or also light and flexible (“ flexible intermediate bulk container “,” FIBC “), the latter also being” big They are often large bags of rectangular or round cross-section.
- the RIBCs often made of metal or plastic, are often used for the transport of liquid or pasty substances, and FIBCs are often used for the transport of bulk materials, eg building materials such as sand, gravel or stones, but also of pharmaceutical substances, foodstuffs or their intermediates
- a description of such FIBCs can be found in the DIN EN standard 1898 (definition for flexible large packaging (FIBC)).
- FIBCs are also stabilized by means of an inner and an outer surface Asked or inserted, rigid plates, for example made of wood or metal, but due to a need for adjusting or insertion material surplus in inner and an outer surface, so a "game” between these surfaces, the handling of such FIBCs in particular before the filling difficult and the stability is reduced.
- the bag wall is made of a flexible multi-layer material in which one of the layers, but not one outer, consists of a soft, resilient foam material and this layer reseals a puncture opening due to its softness and compliance.
- the container side wall of the container according to the invention is light, stable, easy to manufacture and inexpensive.
- the container according to the invention with at least two opposing such container side walls is light, easy to use, is particularly foldable and is characterized by a good dimensional stability, especially in the filled state.
- a transport container may comprise at least one such container.
- the container which is provided for receiving a cargo, comprises a plurality of side walls, wherein at least two opposing side walls are formed as container side walls of the type described above and below.
- a good shape stabilization for example, after an erection of the container, in particular in the filled state, guaranteed.
- a container with a filling volume of 1000 cm 3 could weigh 5 to 15 kg.
- a transport goods container may comprise at least a first and a second container of the type described above and below.
- the transport goods container is therefore on the one hand light and flexible, so at least partially foldable, and on the other hand stable, especially in the filled state. For example, a high lateral stability can be given in particular when filled with liquid or pasty substances.
- the production of the transport goods container is simple and inexpensive, since essentially the same machines are used for the production of the first and second containers and / or similar work steps take place.
- Made of a tissue boundary surfaces ensure high flexibility and low weight. In addition, a good force absorption and force distribution over the tissue is ensured.
- the fabric may comprise, for example, monofilament fibers, multifilament fibers or a combination thereof.
- the fabric at least partially comprises a synthetic and / or natural polymer, in particular a biopolymer.
- the fabric may be at least partially coated with such a polymer.
- the polymer can be selected from a group comprising polyolefins, polyesters, polyamides or a combination. This ensures a high weather resistance, good food compatibility or good hygiene properties. Most preferably, the polymer is polypropylene.

- a web, a seam, an adhesive bond, a welded joint or a combination thereof preferably acts as a connecting means.
- the connecting means is a web, this may in particular be at least a ribbon, a thread, a monofilament fiber, a multifilament fiber, or a binding chain of the fabric, which ensures easy production of the container side wall.
- the cavity can be structured by means of a plurality of webs in communicating fields. As a result, a substantially uniform filling is ensured and thus reduces manufacturing costs and reduces costs; In addition, a uniform force absorption and power transmission is ensured due to a substantially uniform material thickness.
- the shape-stabilizable material may comprise, for example, a liquid, a gel, a foam or a combination thereof.
- This material is thus easy and inexpensive fillable into the cavity, for example by means of pouring, pouring, injecting, blowing, suction or the like.
- this provides a substantially uniform fillability of the cavity and / or distributability of the shape-stabilizable material in the cavity.
- the material may include polyurethane, a resin, Betonit or the like.
- the dimensionally stable material is particularly preferably a rigid polyurethane foam. This is light and dimensionally stable after solidification, which on the one hand a low weight and second, good stabilization properties. Furthermore, thus a good thermal insulation is guaranteed against both heat and cold.

- the shape-stabilizable material can be filled into the cavity, for example by means of a, in particular closable, filling opening. If the filling opening can be closed after the dimensionally stable material has been introduced into the cavity, it is ensured that, when a material that slowly merges into a dimensionally stable shape is filled, it remains in the cavity until at least partial stabilization has been achieved. In addition, the closeability allows the shape-stabilizable material to be easily distributed in the cavity, e.g. by inverting, pivoting or the like.
- edges of a first boundary surface are at least partially connected to edges of a second boundary surface to form the cavity.
- the edges may be e.g. be connected by means of a seam, a welded joint, an adhesive bond or a combination thereof.

- the container may comprise at least one, adjacent to at least one side wall first opening for introducing or filling the transported goods. Additionally or alternatively, the first opening may be an integral part of the boundary surface, or the first opening may at least partially replace a side wall, in particular an upper side wall.
- the container can e.g. a, at least one boundary surface adjacent, comprise a second opening for removal of the transported goods; This results in a simple removability of the cargo, e.g. by pouring out, falling out, trickling out, running out or the like.
- the removal opening is integrated into a bottom of the container.
- the container comprises a first opening, it may be closable, eg by means of a cover flap of flexible or non-flexible material, eg a fabric; if the container comprises a first and a second opening, the first, the second opening or both openings may be closable.
- an insertion or filling aid and / or a removal aid for example a nozzle, a funnel, a chute, a projection and the like may be provided. This can at least partially consist of a flexible material, eg a fabric.
- a nozzle or a funnel made of a flexible material this can be done by means of a clip, a clip, a binder, a tape or be closed like that.
- the removal opening can be produced, for example, for removal, for example by means of a cut.
- a preferred location can be provided and this can be marked for better findability, eg marked in color.
- the first and second openings are arranged opposite to each other, so that a simple and substantially complete insertion and / or filling and removal of the transported material is ensured.
- the first and second openings may be associated with upper and lower side walls.
- the container comprises at least one suspension; this makes a simple transport, e.g. hanging, guaranteed.
- the container comprises one, two, four or more suspensions.
- the suspension may e.g. be connectable with at least one boundary surface or a junction of at least two boundary surfaces. Additionally or alternatively, the suspension can be an integral part of the boundary surface and / or the connection point. This ensures a safe, simple and inexpensive realization of the suspension.
- the container is designed as at least partially foldable, in particular in a substantially empty state. This ensures space-saving and inexpensive storage and transport of the container.
- an outer contour of the first container can be matched to an inner contour of the second container such that the second container can receive or receive the first container.
- the first container for receiving the cargo be provided.
- the first container is referred to here and below as the inner part and the second container as the outer part.
- Particularly preferred two opposite container side walls of the first container and two opposite container side walls of the second container for stabilizing the shape of the transport goods be effective, the opposite container side walls of the first container relative to the opposite container side walls of the second container are arranged such that a total of four shape-stabilizing container side walls arise ,
- the transport container can at least one support, e.g. metal, wood, plastic, biopolymer composite or the like for stabilization.
- the at least one support may be, for example, tubular, rod-shaped, flat or the like, e.g. an angular element, be; additionally or alternatively, the support may e.g. be arranged in at least one corner region.
- each container side wall has at least one over the entire height of the side wall extending and acting as a hinge movement strip, which is free of stabilizable material and whose width corresponds at least to the length of the connecting means.
- both boundary surfaces at least partially made of a tissue and the tissues are impermeable to each other in the region of the moving strip over the entire height of the container side wall for the dimensionally stable material.

Abstract
Description
Die Erfindung bezieht sich auf einen Container mit einer Merzahl von Seitenwänden.The invention relates to a container with a number of side walls.
Die Containerseitenwand fungiert als Stabilisierungsmittel. Derartige Stabilisierungsmittel, wie z.B. sogenannte "Sandwichstrukturen", sind allgemein bekannt und finden in verschiedensten Einsatzfeldern, wie z.B. der Isoliertechnik, LKW -Auf bauten, Hallenbau, Werbetafeln, Bühnenbau, Möbelbau etc., Verwendung. Sandwichstrukturen umfassen in der Regel zwei steife Deckschichten, zwischen welchen sich ein leichteres Kernmaterial, beispielsweise Papierwaben, Leichtholz, Polyurethan, Styropor oder dergleichen befindet. Bei der Herstellung solcher Sandwichstrukturen werden z.B. zunächst die Deckschichten in eine Form eingelegt und von außen mittels Druckplatten im gewünschten Abstand oder in Form gehalten und dann beispielsweise mit Polyurethanschaum gefüllt. Alternativ können bei formstabilen Kernmaterialien die Deckschichten mit dem Kernmaterial in eine Form gespannt und verpresst, verklebt oder verschweißt werden. Diese Herstellung ist verhältnismäßig arbeits- und kostenintensiv und erfordert zusätzliche Formen und Maschinen, welche z.B. auch aufwändig an die zu erreichende Form der Sandwichstruktur oder an Formen der Ausgangsmaterialien angepasst werden müssen, was wiederum die Herstellung der Sandwichstrukturen verteuert. Ein Beispiel eines biologisch abbaubaren, mittels einer Form hergestellten Schichtverbundmaterials mit einer Schicht aus gehärtetem Stärkeschaum kann der
Container für Füllgüter und entsprechende Containerseitenwände sind ebenfalls allgemein bekannt. Ein Beispiel für solche Container sind Tonnen oder Fässer, Kartonagen oder "intermediate bulk container" ("IBC"), welche starr und häufig schwer ("rigid intermediate bulk container", "RIBC") oder auch leicht und flexibel ("flexible intermediate bulk container", "FIBC") sind, wobei letztere auch "big bag" genannt werden und im Wesentlichen große Beutel mit rechteckigem oder rundem Querschnitt sind. Die, oft aus Metall oder Kunststoff bestehenden, RIBCs finden häufig Verwendung beim Transport von flüssigen oder pastösen Stoffen und FIBCs häufig beim Transport von Schüttgütern, z.B. Baustoffen wie Sand, Kies oder Steinen, aber auch von pharmazeutischen Stoffen, Nahrungsmitteln oder deren Intermediaten. Eine Beschreibung solcher FIBCs findet sich in der DIN EN Norm 1898 (Festlegung für flexible Großpackmittel (FIBC)).Container for contents and corresponding container side walls are also well known. An example of such containers are tons or barrels, cardboard boxes or "intermediate bulk container "(" IBC "), which are rigid and often rigid (" intermediate bulk container "," RIBC ") or also light and flexible (" flexible intermediate bulk container "," FIBC "), the latter also being" big They are often large bags of rectangular or round cross-section.The RIBCs, often made of metal or plastic, are often used for the transport of liquid or pasty substances, and FIBCs are often used for the transport of bulk materials, eg building materials such as sand, gravel or stones, but also of pharmaceutical substances, foodstuffs or their intermediates A description of such FIBCs can be found in the DIN EN standard 1898 (definition for flexible large packaging (FIBC)).
Aufgrund der Flexibilität der FIBCs, insbesondere ihrer Seitenflächen, drücken in einen, auf einem festen Untergrund stehenden FIBC eingefüllte Schüttgüter dessen Seitenflächen nach außen, so dass diese eine konvexe Form annehmen und der FIBC bei einem hängenden Transport sogar eine kugelige Form anstrebt. Hierdurch wird zum einen aufgrund einer geringeren Standfläche eine Standfestigkeit des gefüllten FIBCs negativ beeinflusst, und zum anderen aufgrund einer "Ausbeulung" des FIBCs eine effiziente Raumausnutzung bei Transport oder Lagerung verschlechtert.Due to the flexibility of the FIBCs, especially their side surfaces, bulk materials filled into a FIBC supported on a solid ground push its side surfaces outwards so that they assume a convex shape and the FIBC even tends to reach a spherical shape when suspended. As a result, on the one hand due to a smaller footprint, a stability of the filled FIBC is negatively affected, and on the other hand deteriorates an efficient use of space during transport or storage due to a "bulging" of the FIBCs.
Bisher werden zur Verringerung der "Ausbeulung" starre Holz- oder Kunststoffplatten in den FIBC eingestellt; hierbei kontaktieren jedoch die Platten das Füll- und oder Transportgut und die Platten müssen gegen Kippen oder Umfallen gesichert werden, was eine Handhabung vor und beim Befüllvorgang erschwert und Kosten erhöht. Alternativ werden zur Stabilisierung des FIBCs auch über Eck angebrachte Verspannungen verwendet, welche jedoch ebenfalls das Füll- und oder Transportgut kontaktieren. Dann müssen die Platten mit Durchtrittsöffnungen versehen sein, da ansonsten eine gleichmäßige Befüllung des FIBCs erschwert wird. Zudem ist mittels dieser Maßnahmen nur eine mäßige Begradigung der äußeren Form der FIBCs erreichbar, da vom Füll- und oder Transportgut erzeugte Druckkräfte im Wesentlichen punktuell aufgenommen und/oder übertragen werden, was wiederum Standfestigkeit und Handhabung der FIBCs verringert bzw. erschwert. Des Weiteren werden FIBCs auch mittels zwischen eine Innen- und eine Außenfläche gestellte oder eingeschobene, starre Platten, z.B. aus Holz oder Metall, stabilisiert, wobei jedoch aufgrund eines zum Einstellen oder Einschieben benötigten Materialüberschusses bei Innen- und eine Außenfläche, also eines "Spiels" zwischen diesen Flächen, die Handhabung solcher FIBCs insbesondere vor dem Befüllvorgang erschwert und die Standfestigkeit verringert ist.So far, to reduce the "bulge" rigid wood or plastic plates are set in the FIBC; In this case, however, the plates contact the filling and or transported goods and the plates must be secured against tipping or falling over, which complicates handling before and during the filling process and increases costs. Alternatively, for the stabilization of the FIBC also corner-mounted tensions are used, which, however, also contact the filling and or transport. Then the plates must be provided with openings, otherwise a more uniform filling of the FIBCs is difficult. In addition, only a moderate straightening of the outer shape of the FIBCs can be achieved by means of these measures, since compressive forces generated by the filling and or transport goods in the Substantially recorded and / or transmitted, which in turn reduces stability or handling of the FIBCs or difficult. Furthermore, FIBCs are also stabilized by means of an inner and an outer surface Asked or inserted, rigid plates, for example made of wood or metal, but due to a need for adjusting or insertion material surplus in inner and an outer surface, so a "game" between these surfaces, the handling of such FIBCs in particular before the filling difficult and the stability is reduced.

Vorteilhafterweise ist die Containerseitenwand des erfindungsgemäßen Containers leicht, stabil, einfach herstellbar und preiswert. Zudem ist der erfindungsgemäße Container mit zumindest zwei sich gegenüberliegenden solchen Containerseitenwänden leicht, einfach zu verwenden, ist insbesondere faltbar und zeichnet sich durch eine gute Formstabilität speziell im befüllten Zustand aus. Ein Transportgutbehälter, kann zumindest einen solchen Container umfassen.Advantageously, the container side wall of the container according to the invention is light, stable, easy to manufacture and inexpensive. In addition, the container according to the invention with at least two opposing such container side walls is light, easy to use, is particularly foldable and is characterized by a good dimensional stability, especially in the filled state. A transport container, may comprise at least one such container.
Diese Aufgabe wird erfindungsgemäß mit einem Container mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with a container having the features of
Somit ergibt sich eine einfache Herstellung und Konfektionierung der Containerseitenwände, da eine Form der Containerseitenwände mittels einer Form des Hohlraumes bestimmbar ist. Ein Arbeits-, Material- und Kostenaufwand wird somit verringert, da eine Verwendung aufwändiger Formen oder Maschinen entfällt. Zudem ist hierdurch eine hohe Schnitt- und Stichfestigkeit gegeben, sowie eine hohe Weiterreißfestigkeit.This results in a simple production and packaging of the container side walls, since a shape of the container side walls can be determined by means of a shape of the cavity. A labor, material and cost is thus reduced, since a use of complex forms or machines deleted. In addition, this provides a high cutting and puncture resistance, as well as a high tear propagation resistance.
Der Container, welcher zur Aufnahme eines Transportgutes vorgesehen ist, umfasst eine Mehrzahl von Seitenwänden, wobei zumindest zwei sich gegenüberliegende Seitenwände als Containerseitenwände der eingangs und im Folgenden beschriebenen Art ausgebildet sind. Hierdurch ergibt sich eine leichte Bauweise des Containers, welcher zudem flexibel, also z.B. zumindest teilweise faltbar, ist. Außerdem ist eine gute Formstabilisierung z.B. nach einem Aufrichten des Containers, dabei insbesondere im befüllten Zustand, gewährleistet. Beispielsweise könnte ein Container mit einem Füllvolumen von 1000 cm3 5 bis 15 kg wiegen.The container, which is provided for receiving a cargo, comprises a plurality of side walls, wherein at least two opposing side walls are formed as container side walls of the type described above and below. This results in a lightweight construction of the container, which also flexible, so for example, at least partially foldable, is. In addition, a good shape stabilization, for example, after an erection of the container, in particular in the filled state, guaranteed. For example, a container with a filling volume of 1000 cm 3 could weigh 5 to 15 kg.
Ein Transportgutbehälter kann zumindest einen ersten und einen zweiten Container der oben und im Folgenden beschriebenen Art umfassen. Der Transportgutbehälter ist somit zum einen leicht und flexibel, also zumindest teilweise faltbar, und zum anderen stabil, insbesondere im befüllten Zustand. Beispielsweise kann eine hohe Seitenstabilität insbesondere bei einer Befüllung mit flüssigen oder pastösen Stoffen gegeben sein. Des Weiteren ist die Herstellung des Transportgutbehälters einfach und preiswert, da im Wesentlichen die gleichen Maschinen für die Herstellung des ersten und zweiten Containers verwendet werden und/oder ähnliche Arbeitsschritte dabei erfolgen.A transport goods container may comprise at least a first and a second container of the type described above and below. The transport goods container is therefore on the one hand light and flexible, so at least partially foldable, and on the other hand stable, especially in the filled state. For example, a high lateral stability can be given in particular when filled with liquid or pasty substances. Furthermore, the production of the transport goods container is simple and inexpensive, since essentially the same machines are used for the production of the first and second containers and / or similar work steps take place.

Wenn das Verbindungsmittel ein Steg ist, kann dieser insbesondere zumindest ein Bändchen, ein Faden, eine Monofilamentfaser, eine Multifilamentfaser, oder eine Bindekette des Gewebes sein, was eine einfache Herstellung der Containerseitenwand gewährleistet.A web, a seam, an adhesive bond, a welded joint or a combination thereof preferably acts as a connecting means. If the connecting means is a web, this may in particular be at least a ribbon, a thread, a monofilament fiber, a multifilament fiber, or a binding chain of the fabric, which ensures easy production of the container side wall.
Der Hohlraum kann mittels einer Vielzahl von Stegen in miteinander kommunizierende Felder gegliedert sein. Hierdurch wird eine im Wesentlichen gleichmäßige Befüllbarkeit gewährleistet und somit ein Herstellungsaufwand verringert und Kosten reduziert; zudem ist eine gleichmäßige Kraftaufnahme und Kraftübertragung auf Grund einer im Wesentlichen gleichmäßigen Materialstärke sichergestellt.The cavity can be structured by means of a plurality of webs in communicating fields. As a result, a substantially uniform filling is ensured and thus reduces manufacturing costs and reduces costs; In addition, a uniform force absorption and power transmission is ensured due to a substantially uniform material thickness.
Weiterhin bevorzugt kann das formstabilisierbare Material beispielsweise eine Flüssigkeit, ein Gel, ein Schaum oder eine Kombination daraus umfassen. Dieses Material ist somit einfach und kostengünstig in den Hohlraum füllbar, z.B. mittels Schütten, Gießen, Injizieren, Einblasen, Saugen oder dergleichen. Zudem ist hierdurch eine im Wesentlichen gleichmäßige Befüllbarkeit des Hohlraums und/oder Verteilbarkeit des formstabilisierbaren Materials im Hohlraum gegeben. Beispielsweise kann das Material Polyurethan, ein Harz, Betonit oder dergleichen umfassen.Further preferably, the shape-stabilizable material may comprise, for example, a liquid, a gel, a foam or a combination thereof. This material is thus easy and inexpensive fillable into the cavity, for example by means of pouring, pouring, injecting, blowing, suction or the like.

For example, the material may include polyurethane, a resin, Betonit or the like.
Besonders bevorzugt ist das formstabilisierbare Material ein Polyurethan-Hartschaum. Dieser ist leicht und nach einem Verfestigen formstabil, was zum einen ein geringes Gewicht und zum anderen gute Stabilisierungseigenschaften bedingt. Des Weiteren ist somit eine gute thermische Isolierung sowohl gegen Wärme als auch Kälte gewährleistet.The dimensionally stable material is particularly preferably a rigid polyurethane foam. This is light and dimensionally stable after solidification, which on the one hand a low weight and second, good stabilization properties. Furthermore, thus a good thermal insulation is guaranteed against both heat and cold.
Das formstabilisierbare Material ist im Hohlraum, zumindest temporär, in eine im Wesentlichen formstabile Form überführbar. Dies kann z.B. durch Polymerisation, durch Aushärten, Erstarren, Zusammenschmelzen, Verkleben oder dergleichen erreicht werden und kann für eine begrenzte Zeit oder dauerhaft vorgesehen sein.The shape-stabilizable material is in the cavity, at least temporarily, can be converted into a substantially dimensionally stable form. This can e.g. can be achieved by polymerization, by curing, solidification, fusing, gluing or the like, and may be provided for a limited time or permanently.

Zudem ermöglicht die Verschließbarkeit, dass das formstabilisierbare Material einfach im Hohlraum verteilbar ist, z.B. durch invertieren, schwenken oder dergleichen.The shape-stabilizable material can be filled into the cavity, for example by means of a, in particular closable, filling opening. If the filling opening can be closed after the dimensionally stable material has been introduced into the cavity, it is ensured that, when a material that slowly merges into a dimensionally stable shape is filled, it remains in the cavity until at least partial stabilization has been achieved. In addition, the closeability allows the shape-stabilizable material to be easily distributed in the cavity, e.g. by inverting, pivoting or the like.
Bevorzugt sind Kanten einer ersten Begrenzungsfläche zumindest partiell mit Kanten einer zweiten Begrenzungsfläche verbunden, um den Hohlraum zu bilden.

In addition or alternatively, for at least one opening, an insertion or filling aid and / or a removal aid, for example a nozzle, a funnel, a chute, a projection and the like may be provided. This can at least partially consist of a flexible material, eg a fabric. For example, if a nozzle or a funnel made of a flexible material is present, this can be done by means of a clip, a clip, a binder, a tape or be closed like that. In addition or alternatively, the removal opening can be produced, for example, for removal, for example by means of a cut. In this case, for example, on the surface of one of the container side walls a preferred location can be provided and this can be marked for better findability, eg marked in color.
Besonders bevorzugt sind die erste und zweite Öffnung einander gegenüberliegend angeordnet, so dass ein einfaches und im Wesentlichen vollständiges Einführen und/oder Einfüllen und Entnehmen des Transportgutes gewährleistet ist. Beispielsweise können die erste und zweite Öffnung einer oberen und einer unteren Seitenwand zugeordnet sein.Particularly preferably, the first and second openings are arranged opposite to each other, so that a simple and substantially complete insertion and / or filling and removal of the transported material is ensured.

Besonders bevorzugt können zwei gegenüberliegende Containerseitenwände des ersten Containers und zwei gegenüberliegende Containerseitenwände des zweiten Containers zur Formstabilisierung des Transportgutbehälters wirksam sein, wobei die gegenüberliegenden Containerseitenwände des ersten Containers im Verhältnis zu den gegenüberliegenden Containerseitenwänden des zweiten Containers derart angeordnet sind, dass sich insgesamt vier formstabilisierende Containerseitenwände ergeben.In the transport goods container, an outer contour of the first container can be matched to an inner contour of the second container such that the second container can receive or receive the first container. In particular, the first container for receiving the cargo be provided. The first container is referred to here and below as the inner part and the second container as the outer part. Particularly preferred two opposite container side walls of the first container and two opposite container side walls of the second container for stabilizing the shape of the transport goods be effective, the opposite container side walls of the first container relative to the opposite container side walls of the second container are arranged such that a total of four shape-stabilizing container side walls arise ,
Dabei kann der Transportgutbehälter zumindest eine Stütze, z.B. aus Metall, Holz, Kunststoff, Biopolymer Verbundmaterial oder dergleichen, zur Stabilisierung umfassen. Die zumindest eine Stütze kann beispielsweise rohrförmig, stabförmig, flach oder dergleichen, z.B. ein Winkelelement, sein; zudem oder alternativ kann die Stütze z.B. in zumindest einem Eckbereich angeordnet sein.In this case, the transport container can at least one support, e.g. metal, wood, plastic, biopolymer composite or the like for stabilization. The at least one support may be, for example, tubular, rod-shaped, flat or the like, e.g. an angular element, be; additionally or alternatively, the support may e.g. be arranged in at least one corner region.
Gemäß der Erfindung weist jede Containerseitenwand wenigstens einen sich über die gesamte Höhe der Seitenwand erstreckenden und als Scharnier arbeitenden Bewegungsstreifen auf, der frei vom stabilisierbaren Material ist und dessen Breite zumindest der Länge der Verbindungsmittel entspricht. Mit Vorteil bestehen hierbei beide Begrenzungsflächen zumindest teilweise aus einem Gewebe und die Gewebe sind im Bereich des Bewegungsstreifens über die gesamte Höhe der Containerseitenwand für das formstabile Material undurchlässig miteinander verbunden. Die Verbindung erfolgt dabei insbesondere durch ein Vernähen oder ein miteinander Verweben der beiden Gewebe. Bei einem Befüllen der Containerseitenwand mit dem formstabilisierbaren Material bleibt der so gebildete Bewegungsstreifen frei vom formstabilisierbaren Material und behält dadurch seine Flexibilität, so dass der Bewegungsstreifen als Scharnier arbeiten kann. Hierdurch wird erreicht, dass die Containerseitenwand auch im mit formstabilisierbaren Material befüllten Zustand faltbar ist. Mit Vorteil weist die Containerseitenwand an zwei sich gegenüberliegenden Enden jeweils einen Bewegungsstreifen sowie einen dritten Bewegungsstreifen zwischen den beiden ersten Bewegungsstreifen auf. Auch hier sind die Streifen jeweils frei vom formstabilisierbaren Material und deren Breite entspricht zumindest der Länge des Verbindungsmittels. Durch diese Ausgestaltung wird eine noch bessere Faltbarkeit der Containerseitenwand erreicht, wenn diese mit weiteren Containerseitenwänden zu einem Container verbunden wird. Bei dem erfindungsgemäßen Container sind wenigstens zwei sich gegenüberliegende Containerseitenwände mit einer oder mehrerer Ausgestaltungen des oder der vorgenannten Bewegungsstreifen ausgestattet. Mit Vorteil weist der Container dabei eine im Wesentlichen kubische Form mit vier erfindungsgemäßen Containerseitenwänden auf, von denen zumindest zwei sich gegenüberliegende Containerseitenwände jeweils drei Bewegungsstreifen der zuvor genannten Art aufweisen. Hierdurch ist eine platzsparende Faltung des Containers im entleerten Zustand möglich. Der Boden und die Decke des Containers werden bevorzugt von einem Gewebe mit jeweils einer verschließbaren Öffnung zur Befüllung bzw. Entleerung des Containers gebildet.According to the invention, each container side wall has at least one over the entire height of the side wall extending and acting as a hinge movement strip, which is free of stabilizable material and whose width corresponds at least to the length of the connecting means. Advantageously in this case both boundary surfaces at least partially made of a tissue and the tissues are impermeable to each other in the region of the moving strip over the entire height of the container side wall for the dimensionally stable material. The connection takes place in particular by sewing or interweaving the two fabrics together. When filling the container side wall with the dimensionally stabilized material of the movement strip thus formed remains free of dimensionally stable material and thus retains its flexibility, so that the movement strip can work as a hinge. This ensures that the container side wall is also foldable in filled with shape stabilizable material state. Advantageously, the container side wall at two opposite ends in each case a movement strip and a third movement strip between the two first movement strips. Again, the strips are each free of dimensionally stable material and their width corresponds at least to the length of the connecting means. By this embodiment, an even better foldability of the container side wall is achieved when it is connected to further container side walls to a container. In the container according to the invention at least two opposing container side walls are equipped with one or more embodiments of or the aforementioned movement strips. Advantageously, the container has a substantially cubic shape with four container side walls according to the invention, of which at least two opposing container side walls each have three movement strips of the aforementioned type. As a result, a space-saving folding of the container in the deflated state is possible. The bottom and the ceiling of the container are preferably formed by a fabric, each with a closable opening for filling or emptying of the container.

Zudem ist der Hohlraum 18 mit einem formstabilisierbaren Material 18a, z.B. einem Polyurethanschaum, insbesondere einem Polyurethanhartschaum, füllbar. Dabei verteilt sich das formstabilisierbare Material 18a in den Feldern 24, da diese miteinander in Kontakt stehen (kommunizierende Felder), so dass sich nach einem Verfestigen des Schaums eine im Wesentlichen steife Containerseitenwand 10 mit der Fähigkeit zur Kraftaufnahme und -verteilung ergibt. Eine Form der Containerseitenwand 10, z.B. eine flächige Form, ergibt sich im Prinzip aus einer Form des Hohlraums 18, dem Abstand der Begrenzungsflächen 12a, 12b und einem Füllvolumen. Dabei bestimmen die Längen der Stege 22 eine Dicke der Containerseitenwand 10, jedoch kann es in nicht mittels Stegen 22a, 22b, 22c, 22d verbundenen Bereichen in gewissen Grenzen zu kissenartigen Aufwölbungen der Felder 24 kommen. Die Füllung des Hohlraums 18 mit dem formstabilisierbaren Material 18a erfolgt dabei beispielsweise über eine zumindest teilweise offene Kante 16, oder eine Einfüllöffnung 26. Im Falle einer Einfüllöffnung 26 kann diese nach dem Einfüllen oder dem Verfestigen des formstabilisierbaren Materials 18a verschlossen, z.B. abgebunden, zugenäht oder dergleichen, werden.In addition, the
