Definitions

  • the invention relates according to the generic state of the art after Preamble of claim 1 a large bag for pourable and / or flowable goods.
  • Such a large bag is known from DE-A-4 115 345.
  • a disadvantage of the known large bags is that they stand up freely, one have a relatively large space requirement. The reason for this is the bulging of the flexible outer skin of the large bag as a result of the bulk material pressure acting from the inside. If the large bag mentioned is placed on an industrial pallet, its outer walls usually arch over the basic cross-section the range. The known large bags are therefore only with restrictions suitable for being sold in large rack stores for industrial pallets will.
  • the invention is based on the object to create a big bag for pourable and / or flowable goods which manages waiving additional technical aids with a small storage area.
  • the wall consists of flexible tear-resistant film, preferably made of the same material as the cover, and The vertical edges of the wall are on the inside of that area fixed outer skin, preferably by welding.
  • a large bag has been particularly suitable emphasized, which is characterized in that the two shorter and two in contrast, longer side walls, a rectangle with a Spread the aspect ratio of about 2: 3.
  • edge strips of the wall and diagonal wall are interconnected, preferably by welding.
  • the openings have the shape of elongated horizontal ovals in have the walls or diagonal walls. This way large openings with sufficient stretch-resistant design of the walls and diagonal walls.
  • the large bag shown in the drawing with a volume of at least 0.5 m 3 consists essentially of a tear-resistant film or a tear-resistant fabric material.
  • a fabric made of polyester fibers, which is PVC-coated on both sides, has proven particularly useful. If food is to be transported in the large bag, it is advisable to coat it with polyurethane at least on the inside.
  • the overall flexible bag has the basic shape of a block with right-angled Corners and edges on.
  • a comparison of Figures 1 and 2 shows the Embodiment a design with two longer side walls 1 and two shorter side walls 2.
  • Upper end wall 3 and lower end wall 4 are tightly welded to the all-round side walls 1,2.
  • Both end walls 3, 4 have a circular opening in their center, which continues in a hose attachment 5.6.
  • the lower end wall 4 can have an approximately frustoconical contour, so that on it slide the bulk material in the manner of a funnel and through the lower hose attachment 6 can emerge. Both can be transported Seal hose extensions 5,6, e.g. by squeezing the Hose attachment 5 or by folding the hose attachment 6 along an edge 7 formed there.
  • the lower tube attachment 6 is first closed, and then the bulk bag on a suitable surface, e.g. one Industrial pallet, offset. Due to the flexibility of the entire outer skin put the lower end wall 4 with the attached to it Hose attachment 6 slightly inwards so that the large bag along the in the Fig. 1 shown level 8 rests on the base. Then takes place the filling of the large bag via the upper hose attachment 5, the finally is also closed.
  • a suitable surface e.g. one Industrial pallet, offset.
  • the walls 10a, 10b extend between the two longer side walls 1.
  • the arrangement the vertical walls 10a, 10b is such that through the walls 10a, 10b the interior of the large bag into three of the same size Chambers 12a, 12b, 12c is divided.
  • the end chambers 12a, 12c are divided again by the diagonal walls 11a, 11b, 11c, 11d.
  • Diagonal walls extend between the center line 13 of the shorter side wall 2 and that line 14 on which the nearest wall 10a or 10b hits the longer side wall 1.
  • Form the diagonal walls 11a, 11b, 11c, 11d therefore together with the associated side walls 1.2 chambers 15 in Shape right-angled triangles in the corners of the large bag.
  • connection between the walls 10a, 10b or diagonal walls 11a, 11b, 11c, 11d and the inside of the outer skin is done by welding of the slides involved.
  • the walls 10a, 10b and diagonal walls 11a, 11b, 11c, 11d are each with vertical edge strips 16, 17, which, as can be seen in FIG. 5, are flat lie on the inside of the outer skin, and are welded there.
  • the on The tensile forces acting on the connecting surfaces can be done without the risk of tearing off particularly well if, as can be seen in FIG.
  • the edge strips are also in this area 16, 17 of wall 10a or 10b and associated diagonal wall 11a, 11b and 11c, 11d welded together, and only then with the inside the outer skin welded.
  • Walls and diagonal walls consist of an expansion-free, flexible Material, e.g. the reinforced fabric used for the outer skin Foil.
