    transport container
    The invention relates to transport containers for flowable materials, in particular for bitumen in heated or cold condition, wherein the container body of the transport container has a substantially truncated pyramidal shape formed with flexible material bottom, side walls and optionally top surface with filling opening, and wherein the side walls in the lower region near the bottom reinforced by stabilization against deformation.
    Transport containers made of flexible material are often brought to the market with the designation Big Bag or Flexible bulk container and serve mainly for the transport of pourable or flowable goods.
    The present invention is based on a prior art, as disclosed, for example, by AT 505 805 A1. This application is concerned with the stabilization of the shape of such a flexible transport container after the filling of bitumen and the object has been achieved in that the fabric panels forming the side walls are provided at the bottom with stabilizing agents which are drawn or sewn into the fabric panels. The concrete disclosure in the figures shows the arrangement of crossed folds which are sewn into the material of the side walls, the seams ending in the course of the fabric panels.
    Even prior to the priority date of said publication, it had been known in practice to provide stabilizing seams in the side walls, for example, by vertical seams that ranged from the bottom edge of the transport bag to about half of the transport bag height.
    Even if such seams and stitched creases in the side walls bring about a certain stabilization of the transport bag shape, they have nevertheless shown disadvantages in practice. On the one hand, the additional seam in the bag wall is an additional step in the sewing process, which increases costs. The reinforcing effect is of the quality of the needlework and the quality of the 2 50 £ 6jip§yfJ / Q / t. * .. * ... * .ί ··
    Fabric material, which does not always make it easy to predict the stabilizer effect on mass products.
    Another disadvantage of seams is that they tend to burst, which either opens the seam and the stabilizer effect is rendered ineffective, or in the worst case leads to a tear on the transport bag. Seams are always associated with a weakening of the sewn tissue. Furthermore, it is disadvantageous that such sewn folds end in the fabric material of the side walls, so that the sometimes very high tensile forces are at least introduced into the tissue and overstretch and damage this tissue in some parts. The strength and dimensional stability of these sutures, as well as other bands drawn or sewn into the panels, depends only on the strength of the fabric.
    The formation of transport containers with a truncated pyramid-shaped container body and arrangement of stiffening sewn fabric folds has for example also been found in DE 84 21 154.7 U1. Another prior art with a truncated pyramid transport bag for bitumen is also the AT 009 644 U1 refer. This also shows the arrangement of an inner lining of plastic film.
    The packaging of bitumen in transport containers made of flexible material brings difficulties. Bitumen is liquid to viscous only at higher temperatures and solidifies at lower temperatures to a cool melt. However, such melts have the property of reacting even at lower temperatures, e.g. Room temperature is not completely rigid. Bitumen behaves like a slowly flowing mass in the cooled state. This is also one of the reasons why so far bitumen has been filled predominantly in dimensionally stable containers such as e.g. in the well-known bitumen barrels. However, these have the disadvantage that they have a high volume even in the unfilled state and that a relatively high transport loss occurs because when emptying the barrels a high percentage of the inner wall of the barrel gets stuck.

    The known problem with flexible packaging containers is that the filled sacks lose their shape during transport, especially when sacks are stacked in containers, with the sacks bulging out sideways. This can also lead to such bulged transport container no longer fit into the containers used for overseas transport.
    The problem of dimensional stability can be exacerbated when low temperatures cause the commonly used material, such as polypropylene or polyethylene, to lose its strength.
    The object of the present invention is to provide packaging containers of the type mentioned, which are self-stabilizing during filling of the liquid bitumen or similar flowable substances and also remain free after settling of the contents and in particular the solidification of the bitumen, without the desired shape to lose. The strength of the container should be maintained even at low ambient temperatures.
    In particular, the object is to avoid the disadvantages described above, and form the stabilizing means for the shape of the container body such that the tensile forces occurring are well absorbed on all sides, so that it does not come in the hard practice of transport industry to a bursting of the transport container , Moreover, there is a need to provide such stabilizers very cost-effective, since in transport for such lost packaging, as it represent the transport container of this kind, the cost issue is an extremely important issue. Another object is to relieve the tissue of the side walls of the tensile forces while also a bias of Stabiiisierungsmittel should be achievable.
    The present invention solves this problem in particular in that the stabilizing means are designed as Stabiiisatorgurte, each crossed the Bodeneckbereiche with the adjacent side edges tensile strength connect, the attachment points of the stabilizer straps are located at the side edges within the lower bottom two-thirds of the total height of the container body. 4 5cfegji Pejg / Gtf. * .. * ··· * ····
    Further advantageous features of the invention can be taken from the claims and the following description and the drawings.
    The invention will be illustrated by way of example with reference to the drawings.
    Fig. 1 shows an oblique view of the transport container according to the invention.
    Fig. 2 shows the transport container with removed outer wall and without inner lining.
    Fig. 3 shows an element of the inner lining prior to insertion into the transport container.
    Fig. 4 shows a horizontal section through the transport container.
    Fig. 1 shows an embodiment of the finished transport container before filling. The container body 1 comprises a bottom 2, four side walls 3, which is concealed in FIG. 1, and the top surface 4 with the filling opening 5 as the upper termination. All these fabrics largely consist of one or more webs of a fabric material which is strong enough to be folded to absorb the high forces and still allowed the lowest possible pack size. Such bags can hold loads up to and exceeding 1,000 kg.
    The side edges 9 are sewn with side seams 14. The bottom edges 19 are formed by a seam, whereby the respective side walls are sewn to the associated edges of the soil. At the upper end of the container body 1, the top surface edge 20, at which the top surface 4 is connected to the upper edge of the side walls 3 runs. In the illustrated embodiment, the top surface edge 20 is reinforced with a sewn-in straps 21. Along the side edges 9 Kantgurte 15 mitvemäht, with two adjacent Kantgurte 15 each form a lifting loop 16 at the upper end.
    The container body is designed like a truncated pyramid, so that the surface of the bottom 2 is larger than the surface of the top surface 4. 5 5of§iip (ä / Fj / ai * * .. * ··· * ····
    According to the invention, the container body is stabilized by stabilizing means in the lower area near the ground. These stabilizing means 6 are provided as stabilizing straps 7 which are each suspended freely, ie without any intermediate attachment to or with the associated side wall from the bottom corner areas 8 to attachment points 10 along the side edges 9. This ensures that the stabilizing means in the form of the fastening straps that are strong when filling the transport container from the inside forces are transmitted to the reinforced areas of the container body, without damaging the tissue. The attachment points 10 are preferably sewn in the lower two thirds of the height of the container body, whereby the bulging of the transport container is largely prevented.
    The stabilizer straps 7 are preferably sewn with a bias in the bag, so that the straps are slightly shorter than the free length between the Bodeneckbereichen 8 and the associated attachment point 10 corresponds. When the transport container is filled, the stabilizer straps, which are inherently stiff, are nevertheless slightly expanded so that the container body can assume the represented truncated pyramidal shape. The tension of the stabilizer straps keeps the shape as good as possible.
    In Fig. 1 is at the top of the container body still the filler neck 22 can be seen, which protrudes through the top surface 4 upwards and is used to fill the contents. With the locking band 25 of the filler neck can be closed.
    Furthermore, the transport container still has conventional information means, such as e.g. a flag 23 with identification means such as barcodes and a document pocket 24.
    In a preferred embodiment, the container body walls at least on the sides and at the bottom of two layers, namely an inner fabric 12 and the outer fabric 11. In the illustration of Fig. 2, the outer fabric of the side walls is removed, so that on the inner fabric 12 of Side walls can look. Also visible are the stabilizer straps 7, each connecting a bottom corner area 8 with the attachment point 10 of the adjacent side edge and thus absorb the tensile forces of the medium. At the crossing points 13 the act

    Holding forces of both crossed straps together, so that at this point the retention force is greatest. The crossing points 13 are preferably in the area in which the transport container would bulge the strongest.
    Even if the illustrated two-layer structure is preferred, it is still within the scope of the present invention to provide only a single-layer structure, ie, the side walls and / or the bottom are made only of a fabric layer. The crossing stabilizer straps 7 may in this case be provided either on the outside of the hull or internally.
    Fig. 3 shows the blank of a film for forming the preferably provided inner lining 17, which results when four such blanks is inserted as an inner layer in the bag. The attachment of the bottom closed inner lining via the attachment tabs 18, which are mitvernäht with the side edges 9. Otherwise, the inner lining 17 hangs freely in the container. Upwardly extends the filler neck 22, which protrudes in Fig. 1 from the top surface 4 upwards.
    4 shows schematically a horizontal section through a transport container according to FIG. 1.
    Each of the four side walls 3 in this embodiment comprises two layers of fabric, namely the outer fabric 11 and the inner fabric 12. Between these layers of fabric intersecting Stabilisatorgurte 7 are arranged, which intersect at the crossing points 13.
    At the side edges 9 are the side edge seams 14, whereby all fabric layers 11, 12 and the ends of the stabilizer straps 7 and the mounting lugs 18 of the inner lining 17 are firmly connected to each other, with even the Kantgurte 15 are sewn. The straps and fabric layers can be sewn in the side seam with an over seam 26 and a security seam 27, as shown in Fig. 4. In the bottom corner area, a warp stitch seam is preferably used, and the bottom edge seam along the bottom edges 19 can also be designed as a chain stitch seam.

    It goes without saying that the inner lining should consist of a film as thin as possible, the softening point of which is slightly higher than the filling temperature of the bitumen. On the other hand, should the inner lining, which is usually taken during unloading with the cold bitumen from the bag, be liquefied when re-heating the bitumen or so softened that it can either be easily removed or incorporated with the bitumen. As a favorable temperature for the filling of the bitumen, for example, 108 ° C called. The softening temperature of the film must be above this 108 ° C, for example 110 ° to 120 ° C.
    The fabrics of the outer transport container are preferably made of polyethylene or polypropylene and their softening point is much higher, e.g. 190 ° to 220 ° C. Preferably, the tissues are coated with PE or PP, thereby strengthening the tissue.
    Not shown in the drawings is the arrangement of warp and weft of the fabric webs. These are usually such that the chain extends perpendicularly from the bottom edge to the top edge and the shot normal to parallel to the bottom edge. Since, as is known, each fabric has the greatest stretchability in the direction obliquely to the warp and weft, the tensile forces are absorbed by the likewise sloping intersecting stabilizer straps and introduced into the side edge seams and bottom corner areas. The tissues may be flat tissue but also round tissue.
    The stabilizer straps should be as strong as possible but still vemähbar. Preferably, multifilament belts are used in which the multifilaments extend in the longitudinal direction of the straps.
    Typical basis weights for the Wandmateria! are 70 to 150 g / m2 for the inner fabric and up to 250g / m2 for the exposed parts of the outer fabric. For example, the outer fabric may have a higher grammage at the bottom than that of the sidewalls. The bottom, the side walls and also the top surfaces may be formed of separate blanks which may be joined together at the edges. It is also possible for the part of the container body formed by the outer fabric to be fastened to the inner fabric only at the outer surface edges.

    Expressing above, that the stabilizer straps are freely suspended between the attachment points with respect to the sidewalls, this means that they are not supported for glass transfer at any point of the inner or outer fabric of the sidewalls. In the loaded state, the tensile forces are introduced only in the side edge seams and Bodeneckbereiche the container body.
    The lower attachment point of the stabilizer straps lies in the bottom corner area 8. This does not have to be exactly the corner at which the bottom edge 19 collides with the respective side edge. The floor corner area also extends into the vicinity of the edges. For example, the lower attachment point is about 3 to 10 cm, preferably about 5 cm above the bottom corner in the side edge 9. It is important that the high tensile forces of stabilizer straps are introduced into the fixed edge seams.
    Among the advantageously used straps, so the stabilizer straps and the Kantgurten with the lifting straps, it should be added that the strength of the transport container can be greatly improved by appropriate choice of material and adapted to the environmental conditions. Depending on the climatic conditions, even very low temperatures of below -30 ° C may occur, where otherwise commonly used materials such as polypropylene become brittle, so that the transport bag is no longer sufficiently stable.
    The solution according to the invention may consist in that the straps for the transport container are dimensioned larger or made of materials which are more resistant to cold, e.g. made of metal mesh, steel wires, polyamide fibers, natural fibers etc.
