Definitions

  • the invention relates to a large-volume container made of thermoplastic material, with side walls, flat top floor and underbody, the top floor has at least one filling and emptying opening and on its outer circumference is equipped with a circumferential carrying and transport ring.
  • Large-volume containers of the type mentioned have the usual design cylindrical container body has a capacity (filling volume) of about 60 to 300 liters and are used for the storage and transport of liquid goods.
  • a generally customary container design as a bung has a filling volume of approx. 220 liters. When storing conventional sheet pans and when transporting in ISO containers leave an useless space between the neighboring ones round container walls.
  • a container according to the preamble of claim 1 is known from DE-U-9 408 722.
  • the free Intermediate volume between stacked barrels according to the invention is in the Compared to conventional round barrels significantly reduced and the utilization of previously unused freight volume (e.g. with ISO containers) increased.
  • the barrel body in its side walls with a horizontal stiffening element Is provided.
  • This will cause the flattened side walls to bulge significantly reduced.
  • the tendency to bulge increases with the occurrence Internal pressure, conditionally z. B. by hydrostatic pressure of the liquid filling material Stacking load or the like.
  • the stiffening element can be inward and / or externally open U-shaped or V-shaped rib-like indentations or formations be trained.
  • this is for a stable barrel body formation horizontal circumferential stiffening element as formed from the barrel wall and thickened casing ring.
  • the jacket ring is during the blow molding of the barrel body by an upsetting process from the wall shaped the barrel body. So that the upset jacket ring is roughly the same Outside diameter like the rest of the barrel wall, it is full circumferential, outwardly open, approximately flat V-shaped indentation.
  • the corner areas of the Container body deep corner indentations formed such that the container body in this horizontal plane has an almost circular cross section. Also this will significantly reduce the tendency to bulge, in particular the lower half of the container with high stacking capacity.
  • the reference number 10 in FIG. 1 denotes a large-volume blow-molded container in the form of a bung made of thermoplastic material with a capacity of approx. 250 liters, which is equipped on the upper container wall with a circumferential L-ring 12 as a handling ring.
  • a circumferential L-ring 12 as a handling ring.
  • two lateral baffles 14 are arranged protected in recessed sheet pits 16.
  • the configuration according to the invention is clear, namely that the barrel body has a cross-sectional area approximating the square shape with slightly outside bulged side surfaces and rounded corner areas.
  • FIG. 2 shows an embodiment with a central bung 14 arranged in a bung 16.
  • a larger filling and emptying opening (diameter, for example 150 mm or 250 mm) which can be closed by means of a screw cap can also be provided.
  • Figure 3 shows a cross section through the wall of a square container body according to the invention; in comparison, a circle of the same circumferential length is drawn over it.
  • This circle is intended to illustrate the tendency of a barrel filled with liquid contents to bulge.
  • the barrel strives to bulge outwards in the flat wall areas and to draw inwards in the corner areas, i.e. to take the circular shape as the least stressed shape.
  • the barrel body - as shown in FIG. 4 - is equipped with a special horizontally encircling stiffening element.
  • the stiffening element is designed as a circumferential casing ring 22, which is made of the material of the barrel wall.
  • the stiffening element is realized by corner indentations 24 directed into the barrel body.
  • the stiffening element (casing ring 22, corner recess 24) is at one level of preferably about 44% - measured from the lower barrel bottom - arranged; kicks there the maximum buckling effort of the square container.
  • the jacket ring 22 is arranged in such a way in a flat V-shaped circumferential recess 20 that the diameter of the casing ring 22 and the remaining barrel body are approximately the same size.
  • the top view of the top of the barrel in FIG. 5 clearly shows the formation of the four corner indentations 24, which are shown as dashed circles. These indentations 24 are formed most strongly in the corner regions and tapering flat towards the flat wall regions lying between them.
  • the container has the largest in the horizontal plane circumferential indentation almost a circular cross section.
  • the ratio of the short radius (to the center of the flat side wall) to the long one Radius (in the corner area) is between 1.05 and 1.34, preferably about 1.22.
  • FIG. 6 shows the axial indentations 26 (axial ribs) arranged in the middle of the side walls of the square-shaped container for stiffening and stabilizing against bulging of the filled container when stacked.
  • this special container design - in contrast to a conventional square container such.
  • B. a thin-walled canister - the flat side walls the axial stacking load, while the corner areas with the corner indentations 24 prevent excessive radial bulge.
  • FIG. 1 A diagonal section illustration is shown in FIG .
  • the container has the greatest cutting width over its opposite corner areas with the corner indentations 24.
  • This illustration also shows the significantly improved volume yield (more than 10%) compared to a cylindrical barrel body.
  • FIG. 8 shows a barrel according to the invention in a stable lateral position 30.
  • the barrel no longer rolls away in an uncontrolled manner without external influence, but can nevertheless be rolled and moved easily in the lateral position over the corner regions.
  • FIG. 9 shows the rolling of a barrel tilted in the inclined position 32. Manual handling and rolling of the barrel over the floor rolling ring in this inclined position is also possible without great effort.
  • Figure 10 shows four square-shaped barrels set up on a standard pallet 34 (1140 x 1140 mm), in which the greatest possible utilization of the free space is achieved.
  • a standard pallet 34 (1140 x 1140 mm)
  • Figure 10 shows four square-shaped barrels set up on a standard pallet 34 (1140 x 1140 mm), in which the greatest possible utilization of the free space is achieved.
