/0 1 80 for HANS-JOACHIM RAMME BY k ATTORNEYS TANK CONTAINERS SUMMARY OF THE INVENTION Containers for piece goods and bulk material are assuming increasing importance in freight traffic. The dimensions and the design of these containers is already becoming largely standardized with the object of avoiding handling difficulties in all parts of the world.

In this connection there are increasing requirements for so-called tank containers which enable liquids to be transported over long distances in large casks and to be transferred into smaller casks in situ. A tank container of this nature must obviously comply with the usual requirements concerning overall dimensions, arrangement and design of the corner fitting and so forth. Furthermore, the tank container must be able to withstand the specified compression stresses.

It is an object of the present invention to provide a tank container which has the maximum possible volume within the prescribed dimensions, adequately meets requirements made in respect of pressure, and which can be insulated to a considerable extent from external stresses.

The present invention involves providing a rigid frame of appropriate strength in which the tank receptacle is merely supported in the region of the four lower corners of said frame, the external dimensions of the tank receptacle corresponding to the internal breadth, height and length of the frame system. With this new design the frame constitutes a system which is closed or balanced from the point of view of the forces encountered, which will safely withstand all external forces, and which remains clear of the actual tank receptacle itself so that the long cylindrical middle portion of the latteris relieved of any excessive external stresses. This enables the design of the tank receptacle to be worked BRIEF'DESCRIPTION OF THE DRAWINGS FIG. 1 is a side elevation of one end of a tank receptacle suitable for use with a tank container or cradle;

FIG. 2 is a view of the end ofa frame system pertaining to the tank receptacle shown in FIG. 1;

FIG. 3 is a front view of the end of the frame system shown in FIG. 2;

FIG. 4 shows the run-off fitting along a section embracing the axis of the tank receptacle;

FIG. 5 is a plan view of the run-off fitting, in which the tank receptacle itself is not shown;

FIG. 6 is a cross-section of the design of the domed cover, which can be used in the tank receptacle according to FIG. 1;

FIG. 7 is a diagrammatic side elevation of the frame system as a whole; and

FIG. 8 is a plan view of one end of the frame system according to FIG. 7, the top half of said drawing showing the upper side of the frame system whilst the lower half is of a plan of the bottom portion seen from above.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The tank receptacle to be used in conjunction with the tank container or cradle according to the invention consists of a cylindrical middle portion 2, with adjoining end sections 3. The end sections are sealed off by dished end portions 4. Rings 5 extend over the entire periphery between the middle portion 2 and the end portions 3, and serve to stiffen and to anchor the tank receptacle. Moreover, stiffening plates 6 which engage with the means in the frame system for anchoring said tank receptacle are welded onto the receptacle walls on both sides of the middle line in the lower halves of the end sections 3.

The run-off fitting 7 is located in the lower side approximately in the region of the lower middle line of the tank receptacle. The run-off fitting 7, on which a connecting flange 8 can be mounted is integral with the tank receptacle and will be described in more detail subsequently. It will be seen however from FIG. 1 that the run-off fitting projects only slightly beyond the external dimensions of the actual tank receptacle. This contributes in considerable measure to the fact that the entire space available within the frame system can be utilized for the tank receptacle.

The tank receptacle shown in FIG. 1 is housed in a closed frame system of appropriate strength said frame system being shown in FIGS. 2 and 7.

As is apparent from FIG. 7 the frame system consists of two end sections 40 and 41, which form separate closed units, the longitudinal struts 1 l of which project beyond the separate frames and are common to both frames. The length of the struts 11 determines the length of the frame system as a whole.

As will be apparent from FIG. 2, the length of the closed frame member indicated at 10 is such that it fits the end portion 3 of the tank receptacle and the stiffening ring 5. Apart from the four longitudinal struts 11 the frame portion 10 consists of vertical frame members 12 and 15 and of cross members 13, 14 and 17. Moreover, both sides of the frame portion 10 are provided with diagonal struts 19, which are secured to the front end of the frame by connecting plates 16.

As will be seen from FIG. 3 the front end is likewise stiffened diagonally by struts 25 in conjunction with connecting plates 22, 23 and 26.

Further connecting plates 18 are provided at the side in the vicinity of the lower corners, towards which extend spatial diagonal brackets 20 extending practically over the entire length of the frame member 10, said brackets being mounted on the two lower longitudinal bearers 11. Suitable stepped portions 21 are provided in the brackets in the region of the ring stiffeners 5 of the tank receptacle, said stepped portions serving to accommodate the rings 5. The brackets engage in the stiffening plates 6 of the tank receptacle. As is apparent from FIGS. 2 and 3, the brackets which are of appropriate strength are directed spatially and diagonally towards the center of gravity of the tank receptacle in such a manner that all forces can be safely absorbed without secondary stresses arising.

It is furthermore apparent from FIGS. 2 and 3 that the dimensions of the tank receptacle are such that they correspond substantially to the internal dimensions of the frame system.

It will also be seen from FIG. 7 that the frame system has two frame sections 40 and 41 which are designed and arranged in a mirror-image relationship, and are interconnected at 42 via the longitudinal bearer. The tank receptacle is shown at 43 in broken lines. The end sections 3 of the tank receptacle are accommodated in the two frame sections 40 and 41 and are anchored therein, while the cylindrical middle portion 2 of the tank receptacle is left substantially free and has no connection with the frame system. Since all forces arising can be absorbed by the end sections, the middle portion remains substantially free from stress.

In order to make full use of the prescribed dimensions of the frame system, it is essential to locate and design the fittings so that they do not make any additional demands on the space available. A particularly advantageous embodiment is shown in FIGS. 4 and 5. In this case the aperture ring 29 is welded to the bottom of the tank receptacle near one end thereof and a dished run-off fitting 7 is welded to said aperture ring. The fitting 7 runs flatly below the bottom of the tank receptacle and extends parallel to the external wall thereof to which it is welded. The effect achieved by this design is that in spite of the full utilization of the available space as shown in FIG. 2, the fitting connected to the flange 8, which latter is moreover secured at 28 to the outer wall of the tank receptacle, is still positioned above the lower cross strut 17 at the front end of the frame system so that it is quite easy to connect hoses thereto.

The design of the run-off fitting ensures that the tank receptacle can be completely emptied and since the discharge is visible its accurate control is also possible.

If bottom discharge is not feasible a sump cup 30 is provided .as a closed insert, shown in dotted lines in FIG. 4, said sump being adapted to be screwed onto the ring 29 with the interposition of a sealing member. A riser pipe 31, through which the vessel can be emptied, can be inserted into the sump.

A factor having a decisive influence on the flat shape of the dished cover is that the cover 33 should be made of thin sheet material and that there should also be a sufficiently large sealing surface in the vicinity of the flange 36. To this end a reinforcing ring 37 following the contour of the flange is welded externally thereto, onto which moreover the other members and especially the hinged plate 38 or the straining plate 39 for the tensioning screws can be welded. By these means the dished cover can be kept very flat, without detrimentally affecting the sealing thereof when the cover is closed. With the arrangement provided the dished cover can be kept within the dimensions of the upper frame member of the frame system.
