Definitions

• the present invention relates to a container for transporting and storing 'fluids, bulk materials or the like, comprising at least one upper exchangeable and upwardly directed flange having a shape corresponding essentially to the circumference of the container top side, and a lower deformable supporting structure exchangeably connected with the container.
• One object of this invention is to provide a container which, in spite of its low weight, is suf ⁇ ficiently strong to pass the above-mentioned tests according to standard specifications.
• a further object of the invention is to provide a container which can be manufactured at low cost and also i- economical in operation.
• the invention provides a container which is of the type mentioned above and which is characterised in that the flange is deformably connected with the container top side by mears of angle pieces mounted opposite one another at the container circumference and comprising a first and a second leg, said first leg being mounted on the said top side, and the second leg being foldably connected with and protruding sub ⁇ stantially perpendicular from said first leg, said second leg also constituting the point of attachment of the flange.
• Fig. 1 is a front view of a container according to the inven ⁇ tion.
• Fig. 2 is a lateral view of the same container.
• Fig. 3 is a top view of the container and an upper flange mounted thereon.
• Fig. 4 is a section on a larger scale taken along line IV-IV in Fig. 3, showing the attachment of the upper flange.
• Fig. 5 is a front view of the container supporting structure.
• Fig. 6 is a late- ral view of said supporting structure.
• Fig. 7 is a top view of said supporting structure.
• Fig. 1 illustrates a container 1 according to the invention.
• the container 1 which preferably is made of metal is cylindrical and carried by a support- ing structure comprising two parallel beams 2, 3, to the ends of which supporting legs 4, 5 are welded.
• An upper annular flange 6 is exchangeably mounted on the top side of the container 1.
• the flange 6 has an opening 7 for attachment of a lifting device (not shown) and a plurality of peripheral hole- in which bolts 8 are inserted for mounting the flange 6 on the container 1, as will be described in more detail below.
• the lower part of the container 1 has peripheral holes in which bolts 9 are inserted for mounting the container 1 on the supporting struc ⁇ ture.
• An outlet 10 from the container 1 is provided at one end of the beam 3. 3 Fig.
• the supporting legs 4, 5 are box girders adapted to be engaged by lifting devices, for example the lifting forks of a truck.
• the parallel beams 2, 3 are designed such that a container 1 may be placed on top of another container, the beams 2, 3 of the upper container 1 resting against the upper flange 6 of the lower container 1. At least three filled containers 1 may be stacked upon each other. To make the container 1 and its contents stand up to a free fall, the supporting structure must be deformable.
• the beams 2, 3 are arranged, in principle, according to one of the elementary cases of structural analysis, i.e.
• Fig. 3 shows the container 1 from above, and with the upper flange 6 mounted on the container top side. At the top side 11 of the container 1, several reinforcing plates 12 of metal are welded. One or two angle pieces 13 of metal are welded to each plate 12. The flange 6 is mounted on these angle pieces
• the container 1 has a centrally positioned manhole cover 14.
• the attachment of the flange 6 will appear from Fig. 4 which shows a section of the flange 6 and an angle piece 13 from which the associated bolt has been removed.
• the reinforc ⁇ ing plate 12 is welded to the top side 11 of the con-, tainer 1.
• a first leg 15 of the angle piece 13 is welded to the top side of the plate 12, while a second leg 16 projects at right angles from said plate 12.
• the second leg 16 of the angle piece 13, and thus also the flange 6, will be bent inwardly against the top side 11 of the container 1.
• the reinforcing plate 12 serves to distribute the forces of impact over a specific surface of the top side 11.
• the leg 16 and thus also the flange 6 will be bent out ⁇ wardly.
• a certain defor ⁇ mation of the container 1 may be accepted without damaging its contents.
• different flanges may be used depending upon the loads that are to be absorbed, and several flanges 6 may be arranged coaxially.
• Figs. 5 and 6 illustrate the supporting structure on which the container 1 is to rest.
• An annular flange 17 is welded to the top side of the beams 2, 3 and has a diameter such that the lower part of the container 1 upon mounting projects beyond the flange 17. Further ⁇ more, the flange 17 has peripheral holes 18 in which bolts 9 (Fig. 1) are inserted when the container 1 is mounted on the supporting structure.
• the supporting structure is deformable to absorb the loads that may arise if the container 1 falls freely on the ground. Different supporting structures may be used, depending upon the magnitude of the loads to be expected.
• Fig. 7 shows how the metal flange 17 is welded to the top side of the beams 2, 3.
• Two parallel stif ⁇ fening rods 19 are welded along chords within the flange 17.
• the flange 17 and the rods 19 are deformable and capable, to some extent, to absorb loads together with the remaining beam structure. Because of the above-mentioned deformation zones at the top side and the lower side of the container, the container may be manufactured from thinner materials and still be able to stand up to the tests mentioned by way of introduction.
• Known containers on the market
• a container accord- ing to the embodiment herein described has a volume 3 of 1.75 m but weighs but 230 kg, even though the same material is used.
• the container, the upper flange and the supporting structure may be designed in a different manner, but without depart ⁇ ing from the inventive idea as defined in the appended claims.
