Such tanks are mainly used for the storage and transport of granular and powdered substances. The tanks can be emptied by tilting or at least partially turning around.

Prior art containers are generally rigid in construction so that there can be no relative movement between the substance to be transported and the wall during transport. In this case, sticking occurs at the interfaces. Attempts have been made to combat this phenomenon by heating the interfaces or by placing bags made of flexible material between the substance to be transported and the wall, into which compressed air is introduced, resulting in local rupture of the frozen mass.

With regard to the prior art, reference should be made in particular to DE application publication 2 351 * + 25, US patent publications 63724 2 931 523 and 3 139 998 and FI patent publication 33107 ·

However, all the solutions described above require external energy and complicate the structure of the tank.

The object of the present invention is to eliminate the drawbacks of the previously known structures and to provide a new and simpler container to be emptied.

The invention is based on the idea that the immediately load-bearing part of the container is made of a sufficiently flexible and strong material which, when the container is turned or tilted, can move with the material. This creates such a large relative movement between the material to be dismantled and the structure supporting it that the supporting structure peels off the frozen and agglomerated mass. By constructing the attachment of the supporting, resilient structure to the load-bearing rigid structure appropriately, relative movement is provided during transport between the immediately supporting structure of the resilient load and the load, whereby a uniform, frozen mass cannot be formed.

More specifically, the container according to the invention is mainly characterized by what is set out in the characterizing part of claim 1.

The invention will now be examined in more detail by means of exemplary embodiments according to the accompanying drawings.

Figure 1 shows in cross-section one embodiment of a container according to the invention.

Figure 2 shows a cross-section of another embodiment of a container according to the invention.

Figure 3 shows in cross-section a third embodiment of a container according to the invention.

Figure 1+ shows in cross-section a fourth embodiment of a container according to the invention.

Figure 5 shows in cross-section a fifth embodiment of a container according to the invention.

The container according to Figure 1 consists of a support frame 1 and parallel, straight ends 1+. The load-bearing part consists of a cradle bounded by ends U and a mat 2 which is freely suspended and sufficiently flexible and flexible from the upper edges 5 of the support frame 1. When the container is turned or tilted at corners 6 or 7, the load tends to move 63724 to the lowest possible position. In this case, the free part of the mat 2 above the load begins to peel off the frozen mass. Final detachment occurs when the tank is turned or tilted so much that the load begins to fall. In this case, the load is permanently detached due to the falling movement and the simultaneous peeling of the mat. When the container is completely turned around, the mat can be dropped to the position 3 shown in broken lines.

Figure 2 shows a container which is otherwise of the same construction as described above, but the mat 2 is also tied from below at 9. In this case, the free movement of the mat is limited so that when completely turned over it can fall to position 3 at most.

Figure 3 shows an embodiment in which the mat 2 consists of a plurality of strips which are not joined as a single mat, but a second strip 10 is placed at the seam point below the strips, which seals and supports the seam point.

Fig. 1 * shows an embodiment in which the mat 2 does not have to be load-bearing, but the load-bearing structure is an outer shell 1 with a curved cross-section, against which the mat 2 rests under the effect of a load. When turned around, the carpet can fall to position 3.

Figure 5 shows a structure different from the previous solutions. In it, the load-bearing cradle consists of a mat suspended from a transverse support 11 of the container 1. The mat 1 consists of ropes, chains or other similar tightening members 12 fastened together with another sufficiently strong and flexible material 13 so that together they form a load-bearing mat 2. Suitably by tightening the ropes 12 and, if necessary, by using suspension ropes or chains 1 in the transverse direction of the mat, the desired shape of the cradle is obtained. When turned around, the cradle falls to position 3. This causes the peeling phenomenon described in the cases described above.
