Description

PRIOR ART

The present invention relates to a flexible bulk material container made from a fabric or a film having a fillable bag and a connecting device for connecting the container to at least one second container arranged adjacent thereto. The connecting device comprises a U-shaped fabric or film extension into which the bag of the second container can be placed and connected by fixing means.

Bulk material containers of the kind described are known from the prior art as Big-Bags or FIBCs (Flexible Intermediate Bulk Containers) and are used primarily for transporting and for storing bulk materials such as sand or gravel on building sites. Typical bulk material containers hold 500 to 2500 litres, cover the area of a Euro pallet and are approx. 0.5 to 2.5 metres high. A bag made from polyester (PES), polypropylene (PP) or polyethylene (PE) is normally used, wherein the plastic is present as fabric material that is interwoven in order to achieve an extremely high resistance to tearing and tensile loadability. In many cases, the bags are made from a PP fabric which is coated internally with a PP/copolymer/PE film in order to guarantee low material permeability and protection against moisture. The individual fabric webs are sewn or welded together to form bags, wherein the bags often have lifting loops on their top sides and a bottom emptying device in the form of a cylindrical discharge connector in the bottom of the bag. The bulk material containers weighing up to 2 tonnes can be lifted with the help of a forklift truck or a crane and emptied by means of the emptying connector. As these containers can be easily filled and emptied, they have a versatile purpose and are not only used as transport and storage containers for bulk material such as wood pellets, almonds, cocoa beans, plastic granulate or sand and gravel bulk material, but also as a functional element when temporarily barricading-off areas and as transportable flood protection.

To overcome this problem, it is proposed in DE 10 2008 026 647.7 and in EP 2532789 A to extend a bulk material container with a U-shaped flexible shoe and to place an adjacent bulk material container in the U-shaped fabric part and to connect the adjacent bag side walls to one another without a gap with the aid of fixing means. This enables a barricading or boundary wall to be easily constructed and dismantled, wherein the bulk material containers can be reused several times as they can be separated from one another without any problems and easily emptied. A disadvantage of the above-mentioned bulk material containers when constructing a separating barrier, such as when constructing a flood-protection wall, to safeguard against landslip or as some other barrier, is that many people and much material are required, in particular that a large quantity of bulk material such as gravel or sand is required for filling the bulk material containers so that a large quantity of bulk material must be acquired and the containers filled by means of suitable excavators or cranes. When the separating barrier is dismantled, excavators or cranes are again necessary and the bulk material must be removed or distributed over a large area. US 6 296 420 B1 discloses an extremely flexible container which is made of woven textile or plastic film and which has a U-shaped extension to connect to adjacent containers. The container can be sealed by a zip fastener by means of a skirt. A plurality of water-fillable cushions, which can be filled by means of a valve, can be placed inside the container. A row of containers of this kind is used as a water-protection wall. A skirt can be fixed to an outside wall of the container to protect against washing away and for securing the flood-protection wall at the base.

Alongside this, a flood-protection wall, which consists of multiple water-fillable and interconnectable tubes which can be laid in a sausage-shaped combination, can be seen from US 5 125 767 B. DE 20 2005 000 885 U1 discloses a self-stabilising Big-Bag, wherein, in order to simplify a filling process, sewn-in air cushion chambers or tubes, which can be inflated before filling for the purpose of stably erecting the bag, are integrated in the Big-Bag. A Big-Bag which has internal panels with cut-outs sewn into the edges as supporting fabric, which serve to stabilise the Big-Bag during the filling process and in the filled state, can be seen from DE 199 49 432 Al.

Likewise, in a similar manner to that described, WO 2008/137168 A2 describes a Big-Bag, wherein stabilising triangular cylinders made from a solid material can be fixed in the side edges to simplify filling of the Big-Bag.

Finally, the subsequently published WO 2012/09849 A1 relates to a Big-Bag with internal panels in which inflatable and fluid-tight stiffening bodies can be inserted in the edge regions separated by the panels. Stiffening plates are sewn into the outside walls in order to stabilise the outside walls.

The object of the invention is therefore to further develop the above-mentioned bulk material container in such a way that a rapid and resource-conserving filling can be achieved with few people and little material, wherein the filling material can be disposed of easily and without residue when dismantling the separating barrier.

This object is achieved by a bulk material container, a filling method, and a use according to the independent patent claims. Advantageous developments are the subject matter of the dependent claims.

DISCLOSURE OF THE INVENTION

In a first inventive aspect, a flexible bulk material container (Big-Bag, FIBC) made from a fabric or a film having a finable bag for constructing a separating barrier, in particular a flood-protection wall, is proposed. The container is distinguished in that the bag comprises at least one stabilisation container, which is designed to be fluid-tight, is sealable airtight in its upper subregion, and is designed in the filled state to effect a stabilisation of at least one bag outside wall or bag edge of the bag. This is achieved in that the stabilisation container is mechanically constrained and fixed with respect to the bag at the top vertical end by a constraining element. The constraining element constrains and fixes an upward movement of the stabilisation container, thus serves to erect and stabilise the bag when the stabilisation container is completely full, and grips the stabilisation container in the bag. Alternatively, according to the invention, the stabilisation container is formed in the shape of a truncated pyramid with a cross section which tapers towards the top, thus gripping the completely filled stabilisation container in the bag. A stable erection of the bulk material container as well as high stability and lateral compressive strength are therefore achieved by the water-filled stabilisation container.

In other words, the invention relates to a bulk material container which consists substantially of a bag made from a fabric or a film. A bag made from such flexible material basically does not hold its shape and is unstable and can only be stabilised by filling with substantially viscous and self-stabilising material such as sand, gravel or viscously flowing compound. If such a bag is filled with an easily flowing fluid such as water, oil or sludge, then even when a bag, which is sealed fluid-tight on all sides, is filled, there is a risk of the container overturning or tipping as neither the bag container per se nor the filling material has sufficient form stability for the container to stand safely and in a laterally compressible manner which is necessary for a function as a separating barrier, in particular flood-protection wall. According to the invention, it is proposed to provide at least in one, in particular in every, vertical edge or side wall of the bag, a fixed or fixable stabilisation container, which can also be oriented horizontally, and which can be filled separately with water and which is sealed airtight in the upper region so that the fluid column, namely water, located therein can build up an internal pressure in the stabilisation container so that the external contour of the bag solidifies its shape and then stabilises the bag. The stabilisation container is preferably made from an identical or similar flexible material to the bag, designed in a completely fluid-tight manner as a container which is closed on all sides and can be sealed airtight in the upper region, for example by a closure device such as a bleed valve or a screw closure. The closure device can comprise a non-return valve so that although the container is finable, it cannot readily be emptied. The fluid-filled stabilised stabilisation container guarantees stable erection of the container, thus enabling it to be filled with non-self-stabilising material such as water or sludge and to maintain high stability and lateral compressive strength for use as a flood-protection wall. This enables the container to be filled with water or sludge, thus enabling a separating barrier, in particular a flood-protection wall, to be constructed easily and without bringing in additional bulk material. A pump, which pumps water or sludge into the self-stabilising container, can be used for filling. The stabilisation container or containers can be filled and also emptied from above by means of the closure device, for example using a suction line, or when bleeding by overturning the container so that fluid can run out of the stabilisation container.

According to an advantageous development of the invention, the bag can substantially have a triangular, rectangular or square base area, and a stabilisation container, which is preferably substantially shaped cylindrically or in the form of a truncated pyramid, can be arranged at least in one, preferably in every, vertical bag edge, wherein in particular each cylindrical stabilisation container has a triangular cross section. It is also conceivable that the base area of the bag is round or oval, and stabilisation containers are arranged at least at one, preferably at a plurality of diagonally opposing points, and connected to the bag lining. In the filled state, the bag therefore forms a substantially cubic shape and can preferably include at least one internal panel which can be interfused with bulk material to form a cubic shape, thus enabling the bag to be formed as a Quadro or Baffle bag, in particular with perforated panels to improve the stability. The internal panels brace the vertical edges, so that, as a result of the internal panels in the vertical edges, a generally triangular bag subregion, in which a stabilisation container can be fitted or fixed, is partitioned off. The stabilisation container can therefore preferably be formed cylindrically and, in particular, with triangular or triangular truncated pyramid-like increasing cross section in the direction of the bottom of the bag. A stabilisation container of this kind can be inserted, sewn-in or otherwise fixed in each of the four vertical bag edges in the bag subregion defined by the internal panels and the corner edges. The upper constraining element can advantageously be made of a flexible, mechanically stable material, for example a reinforced fabric web, a thick film or a similar flexible but mechanically stable and force-transmitting material, and can mechanically constrain a closure device in the upward direction and therefore define the position and insertion height of the stabilisation container, erect the bag when the stabilisation container is completely full and prevent the stabilisation container from slipping out of the bag subregion which is separated-off by the internal panels. According to the invention, a flexible constraining element made from a mechanically stable fabric constrains and fixes an upward movement of the stabilisation container, therefore serves to erect and stabilise the container when the stabilisation container is completely full, and grips it in the bag container. When the bag is folded together and stowed, the container fabric is protected against damage by the flexibility of the constraining element. Basically, it is proposed to choose a cubic form of the bag, i.e. equal length, width and height, wherein the height can vary between 30 cm and 1.50 m and the width and length are matched correspondingly. If a cubic shaped bag is filled, then as a rule it forms a round shape, as the surface area/volume ratio is optimised as a result. To prevent the round bulging of the flexible bag, it is proposed to sew-in internal panels, i.e. fabric pieces which extend over the internal corner edges of the bag, which prevent or minimise a bulging of the bag when the bag is filled and can therefore maintain a semi-square or rectangular cross-sectional shape of the bag. The panels can have cutouts in the form of holes, in particular elliptical or elongated holes, to enable the bulk material to trickle through. This enables a multiplicity of square or rectangular bags, which have substantially planar external surface and can therefore achieve a high density effect in particular to form a flood barrage, to be nestled closely against one another. In order that the internal panels do not interfere with filling, they can be designed to be permeable to bulk material, i.e. in particular have elongated or elliptical panel cutouts, so that the filling material can also penetrate the edge subspace of the bag constrained by the panels. The stabilisation containers can be inserted into the bag subregions which are separated by the internal panels of a conventional Baffle-Bag in order to develop them in an exemplary embodiment of the invention. When filling the stabilisation container, its flexible outside wall can bulge out into the panel cutout and thereby vertically fix the stabilisation container to the internal panel.

According to an advantageous development of the invention, the stabilisation container can include a fluid-tight sealable closure device in the upper container region, in particular a closure valve or a screw closure, preferably with a pressure-relievable non-return valve, which is preferably designed for fluid-filling, for bleeding and/or for emptying the stabilisation container. The closure device can be designed in the form of a quick-release system, e.g. bayonet closure system, plug-in coupling system, Gardena system or similar. The closure device can include a non-return valve for one-way filling or emptying. The non-return valve can be designed to be pressure-relievable; by fitting or attaching an adapter or actuating a mechanism, the non-return valve can thus be made to permanently open in both throughput directions so that fluid or air can flow in and out. By means of the closure device, a stabilising fluid, in particular water, can be introduced into the stabilisation container in order to fill it so that, as a result of the internal fluid pressure, the stabilisation container, which in itself is made of flexible material, becomes rigid and exerts a stabilisation function. In order to fill the bag, which preferably has one stabilisation container per vertical bag edge, a fluid distribution device can be used, in particular a 1 to 4 distribution device which has four filling outlets from a fluid feed, for example a water pump outlet, for simultaneous connection to the closure devices of the four stabilisation containers, thus enabling a bulk material container to be quickly stabilised in one operation. Subsequently or even simultaneously, the remaining bag volume can be filled with water by means of the pump. Preferably, the closure device is fitted with a quick-release coupling and includes a relievable non-return valve, i.e. one which can be opened by means of a clip-on intermediate adapter.

According to an advantageous development of the invention, the stabilisation container can be designed substantially to be fluid-tight on all sides and include at least one, preferably two, closure devices, in particular a closure device in the top region and a closure device as emptying device in the bottom region of the bag. The stabilisation container, in particular made from flexible fabric or textile, can therefore be closed on all sides and fixed, clamped, attached by means of hook-and-loop fasteners, sewn, welded or otherwise fixed in an interlocking manner, to an inside wall or inside edge, or also to an outside wall or outside edge, of the container, and filled and emptied by means of the closure device. A top and a bottom closure device can be used both for filling and bleeding, and, in particular, a bottom closure device can be used for emptying the stabilisation container. This results, in particular, in the advantage of further developing already existing Baffle-Bags or bulk material containers in the manner according to the invention by fixing in an interlocking manner one or more fluid-tight, sealable, bladder-like stabilisation containers which can be filled, bled and emptied by means of at least one closure device.

According to an advantageous development of the invention, the bag can be designed as a Baffle-Bag and include in its vertical internal edges pyramid-cylindrical or triangular-cylindrical subregions separated by internal panels for accommodating fabric film bags as stabilisation containers. Suitable in accordance with the developments already discussed above are fabric film bags, which are produced for example in the form of dunnage bags, i.e. as so-called airbags which can be used as cushioning and supporting means for stabilising and securing goods in containers or closed transport containers. Fabric film bags of this kind can be filled with air or water by means of a closure device, in particular a valve or an airtight screw fitting, wherein, when the internal pressure is sufficiently high, a form-stabilising effect occurs and, when connected to a bag in an interlocking manner, a form-stabilisation of a water-filled bag is achieved. Fabric film bags are available at reasonable cost as mass-produced items in widely varying embodiments and can be inserted into the internal edge region of a Baffle-Bag bordered by internal panels and filled with air or water for stabilisation.

According to an advantageous development of the invention, at least one internal panel can be connected to the bag side wall and the bag bottom of the bag in a fluid-tight manner in order to form the stabilisation container. Here, it is proposed to form both the internal edge region of the bag and the internal panels in a fluid-tight manner, for example coated, or by means of water-impenetrable film, so that the vertical internal edge region together with the fluid-tight internal panels and a connection of the internal panels to the bottom of the bag form a closed stabilisation container along the vertical edge region. In the upper region, the opening can likewise be sealed by an appropriately matched, preferably triangular closure part, in particular with closing device. At the same time, it is conceivable to connect, i.e. glue, weld or sew, the internal panels to the side walls which border the edge region and to the bottom region in such a way as to form a truncated pyramid-like stabilisation container with substantially triangular cross section, wherein the cross section of the stabilisation container tapers upwards. Self-stabilising containers of this kind can be produced cost-effectively, be filled easily and are basically in one piece so that they do not have to be assembled when erected.

According to a non-claimed embodiment, a tube made from folded fabric film material which is fluid-tight at both ends and can be filled and emptied by means of a closure device at least at one end and which, in the filled state, can effect a stabilisation of the bag edge, can be sewn, glued or welded at least in one vertical and/or horizontal bag edge of the bulk material container. In this way, the stabilisation container can be formed permanently connected by substance-to-substance bonding to a vertical or horizontal bag edge by folding a fluid-tight fabric so that a tube can be formed in the fold and said tube sewn, glued or otherwise connected to the bag edge in a fluid-tight manner. At the same time, the excess fabric material in the edge can be sewn, glued or otherwise fixed to the edge in a fluid-tight manner. The two end regions of the tube can be closed by means of appropriately formed fabric pieces, wherein a closure device for filling and emptying the stabilisation container is arranged at least at one end. In this way, the stabilisation container can be connected by substance-to-substance bonding when the container is produced, thus enabling favourable and efficient production and simple handling of the container.

Basically, the bag can be made from any material, in particular plastic such as polypropylene in the form of a film or textile. According to an advantageous development of the invention, the bag can be made of a fluid-tight fabric or a film and an emptying device for emptying the fluid from the bag can be included preferably in the lower region of the bag from the bottom of the bag to a maximum of 25% of the bag height. In this way, water, for example, can be accommodated in the bag which, in contrast to conventional bulk material containers, is designed to be watertight. The container material can be produced from a water-resistant textile or film, for example, or retrospectively coated to be watertight or clad by means of a fluid-tight material. In this way, the stabilisation container and internal filling region of the bag can be filled directly with the fluid and internal bags for accommodating the fluid can be dispensed with. Preferably, the bag has a closure device for emptying the bag along the bottom peripheral region.

According to an advantageous development of the invention, the bag can include a fluid-tight and preferably removable internal bag or bladder which substantially fills the internal volume of the bag between the stabilisation containers, wherein, preferably, the internal bag includes at least one top closure device and one bottom emptying device. In addition or as an alternative to the previous development, a bladder, i.e. a bag which is closed on all sides for accommodating a fluid, can be provided removably or permanently connected in the internal bag region which is bounded by the outside wall and the stabilisation containers, wherein the internal bag preferably includes a closure device for filling and/or for bleeding at least in the top region, and advantageously a closure device for emptying in the bottom region. The internal bag can first be introduced into the internal bag region and filled, or introduced into the bag already in the filled state. The internal bag can be designed as an inliner or film bag.

According to an advantageous development of the invention, the bag and/or the subregions which are separated by the internal panels can be constrained and stabilised at least in the region of the opening edge by at least one transversely tensioned and preferably flexible constraining tape, a skirt, a shoulder, i.e. a folded waist of the flexible bag material, or a preferably flexible cover. The constraining tape can stabilise the external form of the bag in the upper bag region and can serve to fix and connect the stabilisation container or containers to the bag. At the same time, the constraining tape limits the hydraulic or pneumatic expansion of the stabilisation containers, which are filled with water or air and are generally designed as flexible hoses. The constraining tape, the skirt, the shoulder or the cover can be made of a flexible film or a textile fabric and can be designed elastically, e.g. by means of rubbery-elastic subsections, or designed releasably, for example by means of hook-and-loop fastener, rivets, buttons, belt closure or similar.

According to an advantageous development of the invention, the container can include a further fixing element which enables a further container to be fixed in the transverse direction and/or be horizontally stackable one above the other. If, for example, the barrier wall is made thicker in its width or the height of the barrier wall is extended, then a second or more rows of containers can be erected in the transverse direction of the wall, or two or more rows of containers can be stacked one above the other. In order to connect the individual rows to one another, further fixing elements, for example hook-and-loop fasteners, belt or button connectors can be attached to the outsides of the bags and the fabric extensions so that the individual rows of interconnected containers can in turn be connected to one another in order to achieve increased stability and fixing of the container combination. In this way, containers, which are stacked one above the other for example, can be connected to one another by means of a continuous fabric web which can be fixed by means of button, rivet, belt or hook-and-loop fasteners to the outsides of the containers in order to achieve an improved density effect and stabilisation to form a flood wall.

According to a second aspect of the invention, a multi-part or one-piece combination of at least two, in particular 3 to 10 containers, preferably five containers according to the invention, is proposed, wherein the containers are connected by means of a U-shaped fabric extension, or the combination can be formed by means of a fabric web extending over a plurality of container lengths with sewn-in intermediate walls and wherein the combination can be unfolded by erecting a first container for filling. It is therefore proposed to assemble a preassembled combination of two or more containers, with which the individual bags can be arranged in rows next one another and stacked in a compressed manner by placing and connecting the bag in the U-shaped fabric extension, which can also be referred to as the "shoe" of the adjacent container. Alternatively, the combination can be formed in one piece from an appropriately long fabric web with transversely divided sections. Particularly when rapidly erecting the row of containers, this enables a high-speed of filling without tedious connection of the adjacent containers. Particularly when used as a flood-protection wall, with which there may sometimes be a matter of a few minutes or hours to prevent flood damage, a pre-assembled, easily transportable and quickly finable design of a combination of bulk material containers is advantageous. Furthermore, the working steps for erecting the barrier wall on site are minimised. Alternatively, the combination can also be formed from a one-piece U-shaped web which includes sub bag chambers or by means of individual containers, in particular sewn, glued or welded containers, which are permanently connected to one another.

According to a further aspect of the invention, a flood-protection wall comprising at least one bulk material container or a combination according to one of the above-mentioned exemplary embodiments is proposed. The flood-protection wall can be erected without filling with bulk material by simply filling with water. To this end, all that is required is a pump which is able to fill the stabilisation containers with water under pressure. Water is generally available when erecting a flood-protection wall. In inaccessible flooded terrain it is difficult to obtain bulk material such as sand etc., wherein the lightweight container materials can also be transported to the spot by single people or by boat and simple water-filling without heavy equipment is possible.

Starting from the above flood-protection wall, a water-impenetrable fabric for stabilisation and prevention of washing away, which can preferably be designed with at least the width of the protective wall plus at least 50 cm to 400 cm, can advantageously be arranged on the horizontal bottom edge of the wall facing the flood pointing away from the protective wall in the direction of the flood. The ground stabilisation fabric can, for example, be fixed to the U-shaped fabric extension at the bottom centre in the horizontal direction, and the water-impenetrable ground stabilisation fabric serves to stabilise and prevent washing-away of the flood-protection wall. The ground stabilisation fabric limits the risk of washing away on the flood side, wherein the compressive force of the water column on the flexible fabric effects a stabilisation of the wall against slipping due to the pressure of water. A sufficiently large surface area is necessary for this purpose, wherein preferably the stabilisation fabric can be designed with at least half the width of the protective wall plus at least 50 cm to 350 cm in the direction of flood pointing away from the protective wall. Due to the central connection, the direction can be chosen at will. The fabric can therefore be stretched out from the wall at least the width of the protective wall plus 50-400 cm. Accordingly, the fabric should overlap at least 5 cm of the following container and be fixed in an interlocking manner to the side wall of the bag.

According to a further aspect of the invention, a method for filling a container according to the invention or a combination of containers according to the invention is proposed in which, in a first step, the stabilisation container is filled with a fluid, in particular water, to align and stabilise the container or the combination, and, in a second step, the bag is filled with bulk material, in particular sand or gravel, with a fluid, in particular water, with a mixture of fluid and bulk material, or with comparatively small filling or reinforcement bags which are filled with the above-mentioned materials. Filling the stabilisation containers in the first step produces a required vertical stability of the container so that the filling of the bag with a fluid in the second step does not lead to the container being able to fall over and empty. The stabilisation container can be pumped up, for example with water, to a filling pressure of 0.01 bar. At a static loading with one tonne water pressure, the filling pressure should be increased to 0.2 bar. A typical loadability limit of the stabilisation container is reached at approx. 2-3 bar. The stabilisation effect is improved by increasing the filling pressure.

According to a further aspect of the invention, a use of at least one container for forming a flood-protection wall, as landfill, play area or carriageway demarcation, or as a slope stabilisation barrier is proposed. The container can universally be called upon to form a stable separating or barrier wall which can be loaded with lateral pressure. As an example, the use as a flood-protection wall in which the bulk material and/or the contained fluid, in particular water, in the bag can prevent water flowing through is proposed. Play areas for a football or tennis match can be temporarily demarcated or borders can be provided for tracks for motorsport or cycling events for example. Because of the high lateral compressive strength of the interconnected containers, when there is a risk of a slope slipping, a temporary slope stabilisation barrier can be quickly and easily erected by means of the container wall and dismantled once more after the slope has been stabilised. Only a few items of equipment, for example an excavator and a mixer truck and/or a water pump, are required for this purpose.

According to an advantageous development of the above usage possibilities, the containers are formed in such a way that they can be stacked on top of one another and connected to one another preferably with the aid of stacking connection means, in particular by a film or fabric web. In doing so, the topmost stack row is preferably filled with fluid and the bottom stack rows with bulk material. The stackability enables any height of separating wall to be achieved, wherein a high lateral compressive strength and sealing effect can be achieved by a connection with the aid of stacking connection means. The stacking connection means can be made of film or fabric web, preferably of the same material as the individual containers, and can connect the individual container rows and containers to one another with the aid of fixing means such as hook-and-loop fastener, button, press stud, tape or belt connection.

In the figures, the same or similar components are numbered with the same references.

Fig. 1 shows in perspective a first exemplary embodiment of a bulk material container 10 which comprises a bag 12. The bag 12 has a square cross section, wherein the side walls 26 define a top opening edge 36, to which stabilisation containers 100 in vertical bag edges 104 extend from the bottom region 102 of the bag. The stabilisation containers 100 are designed as fabric film bags 106 and are inserted into sub regions 124 separated by internal panels 64 and are made of transparent material so that the filling state of the stabilisation containers 100 can be determined through panel cutouts 68. A bag filling region 128, which can be filled with fluid, in particular water, is defined between the side walls 26 and the internal panels 64. The top closure of the triangular stabilisation cylinder is formed by a screw closure device 112, 114 which is accommodated in a round recess of a triangular constraining element 110. The constraining element 110, which is formed from a reinforced fabric web, serves to accommodate and constrain the screw closure 114 and limits a vertical movement of the stabilisation container 100 in the direction of the bag opening 30 by means of constraining tapes 116 which, as textile tapes with elastic sub elements, guarantee an upper fixing of the container 100.

Fig. 2 shows a plan view on the container 10 of the exemplary embodiment of Fig. 1, wherein a high-strength film internal bag 108 is placed in the bag 12 in the bag opening 30. This defines cylindrical triangular sub regions 124, in which the fabric film bags 106 can be placed. A closure device 112 for bottom emptying of the fluid-tight internal bag 108, which is designed as a bladder 120, is recessed into the bottom 24 of the bag. The fabric film bag 106 has a closure device for filling and bleeding in the side facing the bag opening 36, by means of which the stabilisation container 100 can also be emptied. A further diagram of a bulk material container 10 with cubic bag 12, in which stabilisation containers 100 are arranged in the four vertical side edges 104, is shown in a perspective view in Figs. 3a to 3c. As shown in Fig. 3b, the stabilisation container 100 can have the form of a truncated pyramid with triangular base area. Fig. 3c, which is not part of the invention, shows a form of a cylinder with a triangular base area, wherein the triangle is preferably formed with equal sides and at right angles. Such stabilisation containers 100 can be designed as fabric film bags 106 and, as a rule, have a closure device 112 in the form of an airtight screw cap 114 in the side facing the opening top edge 36 of the bag 12. Preferably, the stabilisation containers 100 can have an emptying device 122 in the end facing the bottom 24 of the bag in order to discharge fluid when emptying the container 10. The emptying device 122 can be designed as a relievable nonreturn valve and therefore also be used for filling. It can also be designed as a screw cap, tap closure or similar. A further exemplary embodiment of a bulk material container 10, which consists substantially of a bag 12 made from flexible material, is shown in perspective in Fig. 4. An emptying device 122 is shown in the lower region 102 of the bag, which is designed to be fluid-tight. Stabilisation containers 100 made from transparent material are provided in the four side edges 104 of the cubic bag 12 in subregions 124 separated by internal panels 64, wherein the internal panels 64 have panel cutouts 68, through which the filling level of the stabilisation containers 100 with water can be checked. The bag filling region 128, which is constrained by the side walls 26 and the internal panels 64, can be filled with water; prior to this, the stabilisation containers must be filled with water in order to stabilise the external shape of the bag 12. Closure devices 112 are provided at the top end of the stabilisation containers 100 for filling with water and for bleeding the stabilisation containers 100. Transversely tensioning constraining tapes 116, which, transversely tensioned over the internal edges, constrain and fix the stabilisation containers and closure devices 112 and prevent them from slipping vertically, are arranged for further stabilisation. The stabilisation tapes 116 are permanently attached, e.g. sewn or glued, to the opening edge 36, or are releasably connected to the opening edge 36, e.g. by means of hook-and-loop fastener, button, zip fastener, rivets etc. The constraining tapes 116 can be made from a textile tape or a film, and they can be designed to be stretch-resistant or elastic, for example by incorporating rubbery elastic intermediate pieces.

Fig. 5 shows a further exemplary embodiment of a bulk material container 10 according to the invention which comprises a bag 12 and a connecting device 14. The bag 12 can be a conventional FIBC or Big-Bag. Triangular stabilisation cylinders 10, which have a closure device 112 at the top end, are arranged on the vertical inside edges 104 of the bag 12. A fabric extension 16 as connecting device 14, which forms a U-shaped "shoe", is attached to one side wall 26. An adjacent container 10 can be placed in this U-shaped fabric extension 16. Fixing means 18, which can produce an interlocking and stretch-resistant connection to a bag 12 of an adjacent container 10, are arranged in the two internal side surfaces of the fabric extension 16. The fixing means 18 can be constructed in two or more parts and comprise fixing elements 22a which can be fixed in complementary fixing elements 22b which are arranged on a bag external surface of the adjacent container 10. Particularly preferably, the fixing means 18 can be formed as hook-and-loop fasteners 58, in particular as hook-side 60 and loop-side 62 of the hook-and loop-fasteners 58. The hook-and-loop fasteners 58 can be formed horizontally as hook surfaces 60 on the opening top edge 36 of the U-shaped fabric extension 16 and vertically on the longitudinal side end of the fabric extension 16 as far as the base surface of the U-shaped fabric extension 16. Accordingly, complementary fixing elements 22b, which, for example, can be formed as the loop side 62 of the hook-and-loop fastener 58, are located on the outer surface of the bag 12. Two adjacent containers 12 can be connected closely to one another or with the formation of a defined intermediate zone 20. Two or more parallel vertical strips of the fixing elements 22b can be arranged on the outer side wall of the bag 12 in order to set up two or more arbitrary gaps of an intermediate zone. This enables two or more, particularly arbitrary, widths of the intermediate zone 20 to be formed. Bag lifting means 44 in the form of lifting loops 46, by means of which, for example, the empty or filled bag can be held open and lifted with the help of a forklift truck, a crane or similar, are arranged on the top edges of the bag 12. The bulk material loaded into the intermediate zone can pour out of the intermediate zone by separating the fixing means.

Fig. 6 shows a flood-protection wall 80 which is formed by a combination of three bulk material containers 10 according to the exemplary embodiment of Fig. 5 which are arranged in a row and are in each case spaced from one another by means of intermediate zones 20. On its outside edges, the first bag material container 10 on the left-hand side of Fig. 6 has fixing means 18 as fixing elements 22b, which are formed as the loop-side 62 of a hook-and-loop fastener 58. At least two different spacings of the intermediate zone 20 can be formed by means of two vertical hook-and-loop fastener strips, for example an adjacent, close concatenation of the containers and a concatenation with an intermediate zone which is 20% of a bag width. One wide vertical strip can be formed instead of two vertical strips. The last bag 10 shown on the right in Fig. 6 has a U-shaped fabric extension 16 in which a further bag can be placed. Inside the fabric extension 16, a fixing element 22a as hook-and-loop strip 60 is arranged horizontally on the opening top edge 36 and vertically at the longitudinal end of the fabric extension 16. The fixing element 22 can, of course, also be arranged on the inner surface of the fabric extension 16 in such a way that a spacing of the intermediate zone 20 can be formed which is arbitrary or adjustable in a plurality of steps. When dismantling the separating wall, one bag container 10 can be lifted out of the other with the aid of bag lifting means 44 in the form of lifting loops 46 and the fixing elements 22 released from one another; however, it is also conceivable to lift two or more containers 10 simultaneously and empty their bulk material from the bags 12 by way of bottom emptying means which are not shown.

Fig. 7 shows a further exemplary embodiment of a container 10 according to the invention which has a bag 12 with bag subregions 124 separated by internal panels 64 and a connecting device 14 in the form of a fabric extension 16. A stabilisation container 100, for example a fabric film bag 106 according to Fig. 3c, can be inserted in the bag subregion 124. The design and type of the fixing means 18 correspond to those of exemplary embodiments shown in Fig. 5 and 6. Closure fabric extensions 32 in the form of closure skirts 34, which are rolled together and fixed by fixing means 66 in the form of strings or tapes, are sewn to the opening top edges 36 of the bag opening 30 of the bag 12. After filling the bag 12, the fixing means 66 can be released and the closure skirts 34 can be connected to one another to close the bag opening 30. It is also conceivable to provide one or more further closure skirts to cover an intermediate zone 20, which, for example, can be connected to a closure skirt of an adjacent container. In this way, a penetration of water through the bag opening 30 and a flushing-out of the bulk material in the event of a flood-protection wall being inundated or in the event of rain can be prevented. Internal panels 64, which effect a shape-holding function in the filled state of the bag 12, are sewn flexibly into the inside of the bag 12, in each case diagonally into the four bag ends, so that the bag 12 is held in a substantially rectangular or square shape in order to form planar contact surfaces with respect to the adjacent bags; this embodiment corresponds to a Quadro or Baffle-Bag design. A plan view on the bulk material container 10 of Fig. 7 is shown in Fig. 8. An internal bag 120, which can be filled with water by means of a screw closure 114, is inserted into the bag filling region 128. Fabric film bags 106 as stabilisation containers 100, which have screw closures 114 identical to the internal bag 120 as closure device 112 on the top side facing the bag opening 30, are inserted into the subregions 124, which are separated by internal panels 64. A fabric extension 16 as connecting device 14, in which an adjacent bulk material container 10 can be placed in order to form a continuous flood-protection wall 82, is arranged at the right hand edge of the figure. The bulk material containers 10 to be connected are attached by means of a hook-side 60 of a hook-and-loop fastener 58. The closure skirt 34 is secured to the bag opening 36 with the aid of fixing means 66 which are formed as a tie fastener.

The joining of two adjacent bulk material containers 10 is shown schematically in Fig. 9, wherein the design of the bulk material container 10 complies with the exemplary embodiment shown in Fig. 7. The two containers 10 are realised by placing the bag 12 of one container in the fabric extension 16 of the other container and connecting the fixing means 18. Each container 10 has internal panels 64 on its vertical longitudinal edges 104, so that stabilisation containers 100 as fabric film bag 106 are placed in the bag subregions 124 separated by the internal panels 64. Vertical and horizontal fixing means 18 are not only located inside the fabric extension 16, but fixing means 18, which, only in the case of a gapless concatenation of two containers 10 without forming an intermediate zone, are able to connect the bag side walls 26 of the two bags 12 of adjacent containers 10 to one another separably and in an interlocking manner, are also located on the mutually opposing lateral outer walls of the containers 10. A substantially rectangular or square filling shape of the bag 12 is maintained by means of internal panels 64 in the filled state of the bags 12. The particular design of the fixing elements 22b on the outside of the bag 12 enables two or more different widths of intermediate zone 20 to be set up.

Figs. 10a, 10b show the design of internal panels 64 to maintain the shape of the filled bags 12 of a container 10 of an exemplary embodiment, wherein stabilisation containers 100 can be placed and fixed in the bag subregions 124 defined by the internal panels. The internal panels 64 can be designed as a Baffle-

Inliner internal bag 108, which has a sealable bottom 24 and can be designed to be fluid or watertight. A schematic plan view on an embodiment of a bulk material container 10 is shown in Fig. 10a. This consists of a bag 12 and a fabric extension 16 as connecting device 14. Two-part fixing means 18, which serve to fix to an adjacent container 10 in an interlocking manner, are arranged on the inside of the fabric extension 16. These can be formed, for example, as the hook-side 60 of a hook-and-loop fastener 58. Furthermore, when two adjacent containers 10 are closely spaced, further fixing means 18 can be arranged on a side wall 26 which is encompassed by the fabric extension 16 in order to connect adjacent side walls of the containers 10 to one another in an interlocking manner. A base stabilisation fabric 148, which can be sewn or glued by substance-to-substance bonding to the fabric extension 16, is arranged under the base of the U-shaped fabric extension 16 in the central region in the direction of extension of the extension 16. Alternatively, the stabilisation fabric 148, which can be made from a watertight fabric, for example a plastic-coated fabric, can also be fixed releasably, for example by means of rivets, eyes or a hook-and-loop fastener, to the underside of the extension 16. The stabilisation fabric 148 can be construed 50 cm to 350 cm in a side of the container 10 which faces the flood. A pocket 150, which runs along the edge of the fabric and which favours a flat design of the stabilisation fabric 148, is arranged on the outer edge of the stabilisation fabric 148. In the longitudinal direction, the fabric 148 has a projection 152 of approx. 15 cm with respect to the shoe-shaped extension 16. Shown schematically on the bottom 24 of the bag 12 is a bottom emptying means 38, by means of which the bulk material or fluid can be emptied once more after filling.

As a result of filling the rectangular bag 12, it can bulge and assume a round external shape. In order to maintain the substantially rectangular shape, internal panels 64 are sewn diagonally into the outer edges of the bag 12, wherein an internal panel 64, as shown in Fig. 10b, includes oval or elongated slot-shaped panel cutouts 68, through which the bulk material can penetrate as far as the inner edges of the bag 12 in order to guarantee homogenous filling of the bag interior. When a stabilisation container 100 is inserted and filled, on building up a minimum pressure, flexible outer regions of the stabilisation container can penetrate the panel cutouts 68 and thereby effect a self-fixing of the stabilisation container 100. Preferably, the stabilisation container 100 can be made from a transparent material or have transparent surface regions so that the filling level of the stabilisation container 100 can be checked through the panel cutouts 68.

Fig. 11 shows the underside 24 of a container 10 in which a bottom emptying means 38 in the form of a reinforced bottom discharge opening 72, which can be sealed by means of a sewn-in string or cord 74, is provided. The bottom emptying means 38 serves to empty the bulk material located in the bag 12 during the dismantling of a barrier wall which is formed from a concatenation of containers 10, so that the bag 12 and the bulk material can be reused. A hose-shaped closure fabric extension 32 in the form of rectangular closure skirts 34 which are sewn to one another and are connected to the opening top edges 36 of the bag opening 30 of a container 10, is shown in Fig. 12. The closure skirts 34 can be fixed to the top edges 36 in rolled-up form with the aid of fixing means 66, for example strings, tapes or belts, the bag 12 can be filled with bulk material and, after filling, the closure fabric extension 32 can be sealed and knotted, for example, to cover the bag opening 30 in order to prevent flushing-out of the bulk material in the event of rain or inundation of the barrier wall. Bag lifting means 44 in the form of lifting loops or lifting straps 46, with the aid of which the container 10 can be lifted and emptied or filled, are attached to the corners of the bag opening 30. A container combination 56, which comprises five bags 12 in a one-piece U-shaped length, wherein the bags are divided by intermediate sewn-in separating walls, is shown in perspective in Fig. 13. In its vertical inside edges, each bag 12 has sewn-in internal panels 64, which have panel cutouts 68, through which the filling level of the fabric film bags 106, which are made of transparent material, can be seen. The top edge of the fabric film bags is closed by a triangular constraining element 110 which fixes the stabilisation container 100 and secures it in the separated bag region 124. A recess for a closure device 112 of the stabilisation container 100, through which the fabric film bag 106 can be filled and bled, is provided in the constraining element 110. To fill the stabilisation container, water is supplied from a water reservoir 130 by means of a pump 132 to a distribution device 134 which is connected by means of water hoses 136 to the closure device 112 for filling. The closure device 112 can include a quick- release coupling system, which enables quick and easy coupling of the water hoses 136 in the manner of a bayonet or snap-in latch. The closure device 112 can include a non-return valve for filling which prevents the fluid from running out. The non-return valve can be permanently reset for opening by means of a reset attachment. By means of the 1-4 distribution device, the four stabilisation containers 100 of each bag 12 can be filled simultaneously and thereby the bag 12 stabilised vertically, thus enabling a rapid filling and therefore the construction of a flood-protection wall 82. The interior of the bag 12 can be filled simultaneously or at a later time. For emptying, the fluid can be pumped out via the closure device 112, wherein an optional non-return valve can be opened by means of an appropriate reset attachment. Fixing means 18 and fixing elements 22 as hook-and-loop fasteners 58, 60, 62 are provided at the front and rear longitudinal end of the container combination 56 in order to connect the combination 56 to a further combination 56 or individual bag containers 10. Lifting loops 46 and bottom emptying means 38 are not absolutely necessary for bulk material containers 10 and combinations 56 of this kind as filling takes place on site and emptying can be carried out by means of a suction hose from above. The bulk material containers can also be combined to form stable, sturdy systems without internal panels 64, e.g. by sewing, gluing or welding to the Big-Bag bags 10. A fluid-tight fabric web, for example made of PP material, is arranged as base stabilisation fabric 148 at the bottom centre of the U-shaped fabric extension 16, for example glued, sewn or releasably fixed by means of hook-and loop fastener, press studs or similar. On the flood side, the base stabilisation fabric 148 is arranged permanently by substance-to-substance bonding or releasably underneath, from the centre fixing towards the flood-protection wall (82), and restricts washing away of the wall 82. Furthermore, the fabric 148 effects a horizontal stabilisation due to the compressive force of the water column on the flexible fabric 148 in the direction of the base so that the wall 82 cannot be moved horizontally by the water pressure. The fabric 148 projects half the width of the protective wall 82 plus 50 cm to 350 cm towards the flood and is fixed to the U-shaped fabric extension of the protective wall 82 at the bottom centrally with respect to the longitudinal axis of the U-shaped fabric which fixes the longitudinal extension of the combination 56. At the same time, the base stabilisation fabric 148 should extend at least 50 cm to 350 cm from the flood-protection wall towards the flood in order to protect against water getting underneath. A pocket 150, which extends over the whole length of the longitudinal edge and which effects a stabilisation of the flat design of the fabric in the event of inundation, is arranged at the free longitudinal end of the fabric 148. In the longitudinal direction of the container combination 56, the fabric 148 has a projection 152 to the next container 10 or combination 56 of approx. 15 cm. A filling scenario of a container combination 56, which is placed between two bulk material containers 10, is shown in Fig. 14 in a side view according to Fig. 14a and a plan view according to Fig. 14b. Here, the flanking bulk material containers 10 are filled with bulk material 52 such as sand or gravel in order to give the flood-protection wall 82 high lateral compressive stability, and the bags 12 defined in the combination 56 are for the most part filled with water 128, wherein bulk material bags 84 are deposited in the central bag 12 in order to achieve a positional fixation and an increase in the specific weight of the central part of the container combination 56.

Fig. 15 shows a sectional view through a bulk material container 10, which is not part of the invention, for a water-fillable, self-stabilising flood-protection wall 82, wherein the bag 12 is formed in one piece with the stabilisation container 100. For this purpose, the internal panels 64 are connected at their top end to the opening top edge 36 of the bag 12, wherein a closure device 112 is arranged on the connecting fabric. The bag 12 and the internal panels 64 are designed to be fluid-tight, wherein the internal panels 64 are connected in a fluid-exchangeable manner with respect to the bag filling region 128 in the lower region 102 in the vicinity of the bag base 24. If water 118 is introduced into the bag opening 30, then, with the closure device 112 open, the water rises into the sub regions 124 which are separated by the internal panels and which serve as stabilisation containers 100, and stiffen the internal edges 104 of the bag 12. Advantageously, the stabilisation containers are filled and emptied at the same time when filling and emptying the container 10. An emptying of the fluid-tight bag 12 can be carried out by an emptying device 122 in the bottom or from above by pumping-out or emptying through the top closure device 112. A peripheral closure skirt 34, which can be fixed in a rolled-up state by string fixing means 66, is fixed to the top opening edge. The bag 12 can be made of a polyester fabric or a tear- resistant and resilient film. The coated polyester fabric can be coated with PU or PVC. The fabric and/or film are welded in a watertight manner.

Fig. 16 shows schematically two rows of bulk material containers 10 which are stacked on top of one another and connected to one another to form an increased height flood-protection wall 80 and which are connected to one another by means of U-shaped fabric extension 16 and formed intermediate zones 20. For this purpose, the bottom stack row 138 is filled conventionally with bulk material, e.g. sand or gravel, or with smaller bags 84 with bulk material for increased stability and compressive strength, and the top stack row 140 is filled at least partially with water. Triangular stabilisation cylinders 100, which have closure devices 112 in the form of airtight screw fittings at the top end, are sewn into the vertical side edges 104 of each container 10 of the top row. Before stacking, the stabilisation containers 100 are filled with water and the bag 12 is then filled with water. This kind of configuration of containers 10 stacked on top of one another can be used to increase the height of a barrier wall, for example of a flood-protection wall with rising water level. A large-area fabric web 42, which can be attached in an interlocking manner to the side walls of the containers by means of further fixing elements 28, for example hook-and-loop fasteners, can be used to strengthen the connection of first and second horizontal stack rows. The fabric web 42 can prevent water penetrating through the gap between first and second container rows and prevent the flushing-out of bulk material. A container combination 56 of a plurality of folded containers 10, which are connected to one another by fixing means and which can be pre-assembled in a highly compact compressed state, is shown in Fig. 17. By pulling apart a first container 10 by the fabric extension 16, this unfolds, wherein the internal panels 64 effect a self-stabilising and shape-providing unfolding of the bag 12. Each bag region includes a Baffle-In liner internal bag 108 which is designed to be fluid-tight and is fixed to the bag walls in such a way that this results in subregions 124 separated by internal panels 64 formed thereby, in which fabric film bags 106 can be placed as stabilisation containers 100. The fabric film bags 106 can be inserted after the container combination 56 has been erected or be already contained in the container combination 56. The bottom emptying means 38 are, as a rule, closed for filling so that the already erected containers 10 can be suspended in a filling device and filled. Pre-assembling a plurality of containers 10 which are connected to one another in a container combination 56 enables filling to be carried out without any problems, for example for rapidly erecting a flood-protection wall.

Finally, Fig. 18 shows a horizontal sectional view XVIIIa (Fig. 18a) and a vertical sectional view XVIIIb (Fig. 18b) through a bulk material container 10, which is not part of the invention, and which comprises a bag 12. The bag 12 has a rectangular base surface and four side walls 26 which define a bag opening 30, wherein stabilisation containers 100, which are connected by substance-to-substance bonding, in this case sewn, to the side seams 146 of the bag 12, are arranged in the vertical side edges 104 and in the horizontal edges 142 which run perpendicular to the front of the container. The stabilisation containers 100 are formed in a tubular shape by folding over a fluid-tight film-coated PP fabric, thus forming tubes 144 which are sealed fluid-tight at the ends with appropriate fabrics. A closure device 144 for filling and emptying is arranged at at least one end. The overlapping fabric material of the tube 144 is sewn at the edges in a fluid-tight seam 146. A closure skirt 34 is also sewn on at the horizontal top edges 36. The vertical and horizontal stabilisation containers 100 are filled with water under pressure up to 0.1 bar so that the container 10 erects itself in a self-supporting manner and the outer shape of the container 10 is retained when the bag opening 30 is filled with water, as a result of which the container 10 is safeguarded against tipping over.

An essential aspect of the invention is that all parts of the container are produced flexibly from fabric so that the containers 10 are easy to transport without stable materials and sharp edges so that no damage can occur to the fabric during transportation or on erection and dismantling.
