  • a projection 36 may be provided at each of the four corners for the embodiment as a cuboid storage container 10 with a quadrangular cross section.
  • the projections can extend triangularly thickening upward in the container side walls.
  • the protrusion 36 may be configured as a projection 36 that runs around the container circumference and / or circumference of the filling opening 16.
  • the wedge-shaped projection 36 can be designed as a receiving console for at least partially receiving the container lid 14.
  • the container lid 14 may be at least partially supported on the projection 36.
  • the storage container 10 may have on its upper side one or advantageously a plurality of transport openings 40 for transporting the storage container 10.
  • transport openings 40 may be formed, for example, after molding the container body 12 by a machining operation or also during molding using a casting core.
  • the transport openings 40 can be designed in particular as a so-called twistlock or as so-called iso-corner. This means that a transport element is inserted into the transport opening 40 and fixed by a rotation in the opening 40. By a reverse rotation, the transport element can in turn be removed from the opening 40. In this way, the storage containers 10 can be easily handled by standardized methods.
  • FIG. 2 shows a plan view of a storage container 10 and container body 12.
  • FIG. 3 A sectional view according to cross section AA is also shown in FIG. 3 shown.
  • the projection 36 has a particular planar chamfer 38.
  • the projection 36 thickened in the direction of the upper side of the storage container 12 by a chamfer 38 extending with respect to the orientation of the container side wall 28, 30, 32, 34 at an angle in a range of ⁇ 10 ° to ⁇ 35 °.
  • the angle is in the FIG. 3 purely exemplary with 22 ° numbered.
  • the transport opening 40 and a container lid 14 to the container body 12 attaching bolt 42 can be seen.
  • the storage container 10 has by way of example four feet 44 at its bottom area.
  • a circumferential base bead 54 may be provided instead of the feet 44.
  • the feet 44 and the Bodenwulst 54 serve as a footprint of the storage container 10. Furthermore, the feet 44 and the circumferential Bodenwulst 54 serve improved stackability.
  • a thickening 60 extending into the container interior.
  • the thickening 60 has a spherical profile with a radius of 50 mm and extends from the container side walls 28, 30, 32, 34 by 135 mm +10 mm / -5 mm and from the container bottom 26 by 110 mm +10 mm / -5 mm into the container interior.
  • the Bodenwulst 54 projects relative to the container bottom 26 by 20 mm, so that in the region of the container bottom 26, a recess 56 between the container bottom 26 and the substrate, not shown, is formed. Since the container is configured cuboid, the recess 56 has a substantially rectangular shape.
  • the bottom bead 54 has along its circumference extending around the base of the container around the same height of 20 mm, so that there is no gap between the bottom bead 54 and the flat ground and, on the other hand, the recess 56 also has a depth of 20 mm.
  • the bottom bead 54 has a width of 50 mm, wherein the bottom bead 54 linearly drops in the direction of the container bottom 26 towards the recess 56 via a fold 58.
