The container contains a main part and two end members, the main part consisting of an outer skin of polyonal cross-section, an inner, stress-bearing skin within the outer skin which is in contact with the latter at the corners, and a plurality of struts which mutually from one end to the other end de; ' The main part extends and between the skins at least one is arranged along one side of the main part and at a distance from the corners, and a flexible bag for receiving the material to be transported, c] nr is arranged within the inner skin.

Conveniently, each end link is a cap that extends over is attached to an open end of the main part and has splashes that lie over the outer skin. Preferably, the splashes are reinforced by tying bands.

If necessary, the end link or jfHes end link can also be used from extensions of a skin of the main part, usually the outer skin, which forms flaps, which be bent inwards so that they are on top of each other and essentially the otherwise open end of the main part Ie ^ close.

The struts made of wood are practical, with one strut in the middle of each side of the main part and the Struts extend parallel to the corners of the main part.

It is particularly useful if the inner and outer skin are made of corrugated fiberboard, the inner skin made of a stronger and heavier material than the outer one

Skin is made. For example, there is the inner Skin made of a double-walled ^ heavy fibreboard material, for example, double-walled A-elute material, while the outer skin is a single-walled lighter material, for example single-walled C-Elute material.

If the outer skin forms a prism with η sides, then the inner skin is expediently enlarged and folded, so that a prism is created, the cross-section of which has the shape of a 2-n-sided star. Preferably has the outer skin has an approximately square cross-section.

The container can be fastened on a pallet in order to facilitate the movement of the container with the aid of a forklift to enable »The pallet is preferably made of wood and contains load-absorbing links below each strut.

The flexible bag usually consists of a length of tubing Kunststof-f materials, the length of the tube being summarized and passed through an opening in the middle of the nine-n end link is guided to at that end of the tube to produce a closure. The other end of the tube is then back over the opposite end of the Haiptteiles folded so that the sack can be filled with the fanned contents from this end. Is the sack full, then the upper end of the tubular material can also be gathered and sealed before the main part is terminated by the upper terminating member. To facilitate the removal of the contents of the Sack also provide a standard dispensing valve.

A particularly advantageous embodiment of a transport container according to the basic principles of the invention is to be used in the following as an exemplary embodiment with reference to the drawings are explained in more detail. The drawings show in

Fig. 1 is a perspective view of a filled container ;

Fig. 2 is a section through the container of Fig. 1, wherein the left side the filled container and the right side of the figure to the right of the dashed line reproduces empty container;

3 is a bottom perspective view of a modified one Embodiment of a container with not shown carrier pallet; and in

Figure 4 is a view of the other end of the container of Figure 5 in a position ready for filling.

The container of Fig. 1 includes a prismatic main part 1, the top and bottom by flanged end caps 2 and 2 is closed. The lower end cap 2 rests on a wooden pallet 4 and is attached to it. The flanges of the lower end cap 2 are expediently attached to the main part 1 with a latex base impact adhesive and reinforced by a binding tape 5 of a glass fiber reinforced adhesive tape.

The main part 1 consists of an outer skin 6 made of simple C-flute corrugated fiber board which is folded along the edges 7 and along an overlap 8 near an edge

is attached. Four lengths of wood are arranged within the outer skin and extend from one end to the other of the main part 1, so that load-bearing struts 9 are created which rest on the lower end cap on the pallet 4 and support the upper end cap 3. The main part 1 also contains an inner skin 10 ₂ which absorbs the load and which only touches the outer skin β along the edges 7 when the container is empty. Recessed folds 11 in the inner skin 10 give the inner skin a star-shaped cross-section when the container is empty. The main part contains a flexible sack, which is not shown in the drawing, but consists of a polyethylene tube which is combined at the lower end and passed through a hole in the lower end cap 2 ₉ while the other end of the tube remains open until the container is filled, and is then combined and covered with the upper end cap 3, which can be glued also on their! splashing with the outer skin 6 ,, while the upper end cap during the IPüllvor passage is open ₉ it may be necessary, the outer skin β to be reinforced with a strapping frame in order to prevent the open upper end of the container from breaking out. If the end cap is fixed in place with its reinforcing flanges, then the struts 9 are securely held and any strapping frame used during the filling process can be removed.

If the container is filled, then the inner skin 10 is through the mass of the material filled into the sack is deformed in such a way that surface contact between the inner skin and the outer skin arises over an area in the vicinity of each edge 7,

- 6 309820/0229

as can be clearly seen on the left of the dashed line in Pig. 2 lying side can recognize. The contact areas between the two skins are indicated at 12 in FIG. 1.

The embodiment according to FIGS. 3 and 4 differs from those according to FIGS. 1 and 2 in that the terminating members are formed by flaps which are integral with the outer skin 6, and not by separate end caps.

In the illustrated embodiment, there are at each end the container uses four flaps. At the lower end (see. Fig. 3) the flaps are indicated by 2a, 2b, 2c and 2d and dimensioned to leave a central opening 20 for emptying the contents of the container can serve. The hatched overlap areas of the flaps are glued together.

At the upper end of the container (FIG. 4) the flaps forming the upper closure members are designated by 3a, 3b, 3c and 3d and dimensioned so that after folding to close the upper part opposite * flaps 3a, 3b, 3c or 3d, just touch each other, so that a double wall thickness of the fiber board extends over the entire surface of the container extends.

The struts 9 », which are preferably attached to the outer skin 6, provide support on each side of the container, which allows two containers of the embodiment shown in Fig. 1 to be stacked on top of one another. The number of containers which can be stacked on top of each other depends on

- 7 -309820/0229

the strength of the struts and the pallet of the container underneath or the containers sitting underneath away. In practice there is no problem with the solidification of these components until there are three containers with a weight of approx. 1000 kg each can be stacked on top of each other.

The corrugations run in the vertical direction in both the inner skin as well as the outer skin, but the corrugations can also be horizontal in one or the other skin run from one edge to the other.

Preferably one strut 9 is used in the middle of each side of the container, but two spaced apart can be used arranged struts can be provided on one or more sides. Use two struts along each side of the Container ", then they should be arranged in such a way that they are arranged between the two areas 12 of each of these sides are. Of the. Distance between the two struts along one side can be near the bottom end cap serve to provide an outlet opening in one side of the container. to be provided for dispensing the contents of the container.

The opening 20 in the terminating member of the embodiment of T? Ig. 3 can be through a passage in the pallet 4 lie, the opening during filling, transport and storage of the container by a destructible Membrane is complete, for example a piece of fiberboard with a pull cord.

If the contents of the container are to be unloaded, the . Membrane torn open and removed, the summarized lower end of the flexible sack out of the passage

pulled and the contents of the sack discharged through the lower end.

In order to ensure that the struts 9 are correctly arranged along one side of the container, one can on each strut, usually attach a cross member near the top which, when perpendicular to the strut, extends from one corner to the other of the outer skin 6. The cross member can be rotatably mounted on the strut so that it is parallel to the strut for easier transport of the parts of a container to an eventual Can pivot erector and user. An embodiment of a transport container according to the present Invention was 1m by 1m (40 inches by 40 inches) in cross-section and 167 cm (66 inches) in height. The container was loaded with 1000 kg (2100 lbs) of granular material and was subjected to a test on a bulk load vibrator, representing a journey of several hundreds of miles about bad roads. The container under test had four 10 cm wooden struts χ 5 cm (4 in. χ 2 in.) used to reinforce the sides. At the end of the trial, they were extensive Vibrations to which they were exposed were not adversely affected in any way.

The components from which a container according to the invention can be produced form a further essential feature of the present invention. In the case of a container according to FIG. 1, a pre-cut folded outer skin 6, a pre-cut and folded inner skin 10, prefabricated struts 9 (with or without pivotable cross members), a pallet 4, two end caps 2 and 3 and were used
