Definitions

  • the invention relates to a block-shaped container for bulk material, which container is made of flexible material and has on the inside stabilisation means fixed to the side walls, for preventing its side walls from bulging out under the influence of the bulk material, and also a filling opening situated on its top side.
  • Such a container is known from European Patent Application EP-A-247696. It is suitable for all kinds of bulk material, while the block shape of the container is to ensure that it takes up relatively little space. If the block shape can be retained, such containers can be placed against each other in such a way that little transport space is lost. Containers made of supple material which lose their block shape cannot be placed against each other in such a way that optimum use of the transport space is obtained. If, for example, they deform to a cylindrical shape, gaps which cannot be put to any good use remain between the adjacent containers.
  • the stabilisation means are provided on its side walls.
  • this known container still has the tendency to assume a cylindrical shape when it is filled completely with the bulk material.
  • the stabilisation means used here provide only a limited solution. Besides, the production costs of this known container can increase considerably if the stabilisation means are fixed on eight different seams over the height of the side walls.
  • the object of the invention is therefore to provide a container of the above-mentioned type which does not have these disadvantages.
  • the stabilisation means contain strips of flexible material which are fixed at one side to a side wall and at the other side to a thin- walled core with a cross-section which is closed in a plane at right angles to the side walls.
  • the core can be a ring or pipe of flexible material, on the outside of which the strips of flexible material run.
  • the whole container, including the stabilisation means can thus be folded up to a small packet, so that transportation to the filling place is facilitated.
  • the stabilisation means according to the invention support the side walls, preferably halfway between the vertical edges of the side walls.
  • the interior space of the container is divided into five parts. In order to ensure that bridging cannot occur in any of these parts during filling or emptying of the container, these five regions have approximately the same surfaces. Each of the surfaces then has a measurement which is large enough to avoid bridging in the bulk material.
  • the filling opening is situated directly above the core, in such a way that the bulk material initially collects in the core, said bulk material pressing the flexible material of the core radially outwards and pulling it taut to a cylindrical shape.
  • the core forms a stable cylinder, under the influence of the radially outward directed pressure force of the bulk material.
  • the material put in then runs over the edge of the core into the areas lying outside and bounded by the strips of flexible material.
  • the bulk material in the process come into contact with the walls of the container and, through the fact that the horizontal measurement of the strips is approximately the same as the distance of the cylindrical wall filled with the bulk material from the side walls of the container, the block shape of the container can still be retained, despite the outward directed bulk material load exerted on the side walls.
  • the container can be opened out by directing a jet of air onto the filling opening.
  • the core of flexible material is also blown open here, in such a way that it is ensured that the bulk material initially collects in said core.
  • the container is suspended by suspension lugs near its top corners.
  • the container is thus opened out, but it is not yet ensured that the core is opened out in a suitable way to take the bulk material.
  • the side walls, near each top corner where the suspension lugs are provided, and the core are fixed to each other by means of pull tapes or cords, in such a way that when the container is suspended the core is held open by said pull tapes or cords.
  • the bulk material will thus initially collect in the core during filling.
  • the side walls each comprise two halves connected to each other by a seam, in which seam a strip is also fixed.
  • the halves of two adjacent side walls can also be integral. In this embodiment only four seams are present in the side walls, which constitutes a major advantage for the production of the container.
  • the seams can be made in such a way that the vertical edges of two wall halves belonging together in each case first run outwards, enclosing the vertical edge of the corresponding strip, then run folded away from each other through l8 ⁇ ° back to the outside of the side wall and, finally, run folded away from each other through 90°, while a cord is sewn into the seam parts running outwards relative to the side wall.
  • This special form of seam ensures that virtually no dust can escape from the inside of the container to the outside.
  • these seams can be produced simply with a standard sewing machine.
  • the container can also be made liquid-tight. This is achieved in a container in which a lining of liquid-tight material is provided, which lining has a slit or cut at the level of each strip, each strip projects outwards relative to the lining through the slit or cut, and the lining edges situated on either side of the strip in each case are fastened together in a liquid-tight manner by means of an adhesive tape which is essen- tially L-shaped.
  • an L-shaped adhesive tape is in each case preferably fixed at one side to the outward projecting edge of the strip and at the other side to the outside of the lining edge in question.
  • a cord can in each case be sewn into a packet comprising a first adhesive tape, a first side wall half, a strip, a second side wall half, and a second adhesive tape.
  • the invention also relates to a method for producing the stabilisation means for a container according to the invention.
  • the strips and the core are in this case made of a self-contained length of flexible material, which length is formed into a square ring or tube, of which two walls are then folded inwards over the central generating line, in such a way that the two central generating lines concerned come to lie near each other, and a packet is obtained with the following lying on each other in succession: an unfolded side wall, two inward folded halves of an adjacent side wall and, finally, an unfolded side wall, .following which the unfolded side walls are fastened each at a distance from their corner edge according to a generating line to the adjacent half of an inward folded side wall, in such a way that a strip is formed in each case between a corner edge and a fixing line, and the wall parts lying between the fixing lines form the core.
  • Figure 1 shows a container in perspective, in which the top side is partially left out.
  • Figure 2 shows a side view of the container, in which a side wall is partially left out.
  • Figure 3 shows a detail of the seam of the container.
  • Figures 4a to 4d show the various stages of filling of the container.
  • Figure 5 shows a first phase of the production of the stabilisation means according to the invention.
  • Figure 6 shows a second phase.
  • Figure 7 shows the finished stabilisation means.
  • Figure 8 shows the side walls of the container for fixing together.
  • Figure 9 shows a cut-away view in perspective of a container with liquid-tight lining.
  • Figure 10 shows a detail of Figure 9-
  • the container shown in Figure 1 comprises side walls 1 to h , and also interior stabilisation means 5- As can also be seen in Figure 2, these stabilisation means 5 have a core 6 of supple material and four flexible edge strips 7. These edge strips 7 are fixed at one side to the core 6 and at the other side to one of the walls 1 to 4 in each case.
  • the container is also provided with a top face 8 and a bottom face 9. each provided with a filling opening 10 and an emptying opening 11 respectively.
  • the supple strips 7 are fixed in the centre of the side walls 1 to 4, in the manner shown in Figure 3-
  • the side walls for example side wall 1
  • the side walls are made up of two halves 12, 13, which together with the supple strips 7 are sewn together.
  • the adjacent edges of the wall halves 12, 13 are, as shown, bent away from each other through 180°, and then bent away in the opposite direction through 90°, in such a way that strips of material between which the flexible strips 7 can be sewn are obtained.
  • Such a seam is highly dustproof. Owing to its ready accessibility, it can be easily made on a standard sewing machine.
  • the wall halves 12, 13 run through into the wall halves of the adjoining side wall, as a result of which a sturdy construction is obtained.
  • suspension lugs 14 Fitted near the corners of the container are suspension lugs 14, by means of which the container can be suspended on a filling or unloading unit.
  • Cords or tapes 15 which are fixed to the core 6 can also be provided near the corners.
  • the core 6 can also be opened out by means of the cords or tapes 15- Such cords or tapes 15 can be dispensed with if the container is opened out by means of a blowing device.
  • Figures 4a to 4d the container is shown, partially cut away, during various stages of filling with a granular material.
  • the core is opened out, either by the blowing open of the container or by means of the cords or tapes 15. not shown here.
  • a certain quantity of material initially collects on the bottom of the container, in such a way that the bottom edge of the core 6 is reached in the end.
  • the core is then filled internally (see Fig. 4b). -Following that, the situation shown in Figure 4c is reached, in which situation the core 6 is filled completely and the material goes into the space determined by the supple strips 7 and the core 6. Only now does the material ' come to rest against the outer walls 4 of the container but, since they can be retained by the strips of supple material and the core 6 stabilised by the bulk material, they cannot bulge outwards.
  • the container is shown completely filled in Figure 4d.
  • Figures 5 to 8 show different stages in the production of stabilisation means and the container walls.
  • a self-contained length of supple material is first of all folded in such a way that a bottom wall 16, a top wall 17 and two folded walls l8, 19 are obtained. These walls are connected to each other by the fold edges 20 and 21.
  • Figure 6 shows that the walls are then fixed to each other by means of the weld seams 22, as a result of which the four flexible edge strips 7 and the core 6 of supple material are obtained.
  • Figure 7 shows all this again when opened out.
  • the side walls of the container are then assembled from strips of supple material each comprising a half 12, 13 of a side wall.
  • the height of the edge strips 7 and the core 6 is less than the height of the wall halves 12, 13, in such a way that the stabilisation means do not run through to the top wall and bottom wall of the container then to be fitted.
  • This top wall and this bottom wall are then also fastened together by means of the dustproof seams shown in Figure 3. the difference being that the supple strips 7 are left out.
  • the container has the side wall halves 12, 13 with edge strips 23, already described above.
  • a top wall 25 and bottom wall 26 are also shown, also with edge strips 27-
  • the lining 24 has a slit 29 in each of its side walls 28.
  • the outer edge 30 of a strip 7 projects through said slit in each case. Strips 7 and core 6 are not visible.
  • each strip 7 is fixed by means of a double L-shaped adhesive tape 31 in a liquid- tight manner to the lining edges adjoining the slit 29-
  • a cord 36 is sewn through the packet comprising the strip 7 and lining 24 and adhesive tape 31• fixed to each other in this way in a liquid-tight manner, on the one hand, and the side wall halves 12, 13, on the other.
  • openings 32, 33 are provided in the top wall 26 and in the bottom wall 25, through which filling and emptying channels 34 and 35 respectively project when the container is assembled. These channels 34, 35 are joined together in the known way to shut off the lining.
  • the adhesive tape 31 is double L- shaped and is folded around the edge 30 of strip 7- In that case cord 36 is also sewn through the adhesive tape halves 31 •
