Stacking containers

The invention relates to a stacking container, consisting of a rectangular container made of foldable material, e.g. plastic, cardboard or paperboard, with foldable side walls and a profile frame with a U-shaped cross-section placed on the side walls and at least one retaining lug arranged on one leg of the profile frame.

Such containers are well known. They are generally used for transport, storage and keeping a wide variety of goods and can be stacked on top of each other thanks to the attached profile frame.

Furthermore, such containers with stacking aids or edge reinforcements are known. Essentially, two variants are used for the formation of the edges. In one variant, U-profiles are attached to all four side walls of the container, reaching to the corners of the container. Special corner connectors are then attached over these U-profiles. The corner connectors, the U-profiles and the container wall are then connected to one another using rivets.

A modified version of the previously known stacking container consists in an endlessly welded profile frame being placed over the container walls and also being attached to the container using rivets.

A special type of profile frame fastening consists in clamping a bent container wall to the retaining lug inside one of the legs.

However, the known designs of the stacking container have the disadvantage that the fastening of the profile frame to the container walls is not optimal. In addition, they are very difficult to assemble in the variant shown above.

The present invention is based on the object of avoiding the disadvantages of the previously known stacking containers and of creating a stacking container with a profile frame fastening that is easy to assemble and wherein the profile frame is securely held on the top of the container.

To solve the problem, a stacking container of the type mentioned at the beginning is proposed, which is characterized in that a rectangular corner connector is arranged in each corner of the container, which has a tab on each of the two legs, over which the respective side wall of the container is folded, wherein the reinforced areas of the middle of the legs have inward-facing projections or thickenings, under the lower edges of which the retaining lug of the attached profile frame engages.

This first embodiment of the stacking container according to the invention achieves the significant advantage that the attached profile frame is not only held securely, but at the same time an excellent corner stiffness of the container is guaranteed. Such a profile frame fastening with corner connector according to the invention has the further advantage that the container, corner connector and profile frame are connected in a force-fitting and form-fitting manner without additional connecting elements.

A particular embodiment of the stacking container according to the invention is characterized in that the corner connectors on the top have outward-facing shoulders which are on the

• · ■ ·

The cut-out outer wall of the container should be approximately flush with the wall. This measure ensures an exceptionally precise fit when placing the profile frame on the side walls of the stacking container.

The solution to the problem posed at the beginning can also be achieved by a stacking container of the type mentioned at the beginning, which is characterized in that at least in one side wall of the container, preferably in all four side walls, at least in one recess, a profile piece having a surface or edge is arranged in such a way that the retaining lug of the attached profile frame engages behind the lower edge of the profile piece.

According to a special embodiment, the profile piece can consist of a U-profile piece that is open at the top, behind whose lower edge the retaining lug of the attached profile frame engages.

Even with such an arrangement of the stacking container, a particularly good fastening of the profile frame and thus good rigidity of the stacking container is ensured.

The drawings will be used to explain in more detail using two preferred embodiments of the stacking containers according to the invention.

As can be seen from Figures 1 to 6 of the drawings, the stacking container according to the invention consists of a rectangular container 1 made of foldable material, e.g. plastic, cardboard or paperboard. This container has foldable side walls 2, 3, 4 and 5. A profile frame 6 with a U-shaped cross section is placed on these side walls.

All four corners of the stacking container are designed the same, and the design is described using a corner 7. Accordingly, a right-angled corner connector 8 is arranged in each corner of the container 1, which is shown in detail in Figures 3 to 5. This

Corner connector 8 has a tab 9, 10 on each of the two leg ends. A side wall 2, 3 that can be folded inwards is placed over each of these tabs, whereby the corner connector is held between the two side walls.

The reinforced areas of the middle of the legs have two inward-facing projections 11, 12, under whose lower edges 13, 14 a profile nose 15 engages, which is arranged inside a leg of the profile frame 6. This achieves an extraordinarily good clamp fastening and excellent final rigidity of the assembled stacking container. The corner connector 8 has an outward-facing, circumferential shoulder 16 on the top, which lies flush on the outer walls of the inwardly folded side walls.

Figures 7 to 11 show a further embodiment of the stacking container according to the invention. In this embodiment, the corner connections can be constructed as shown in Figures 1 to 8. However, it is also possible to use a different corner connection. In the embodiment of the stacking container according to the invention shown in Figures 7 to 11, recesses 17 are provided in the side walls 2, 4, in which U-profile pieces 18 inserted through slots are arranged in such a way that when the profile frame 6 is placed on top, the retaining lugs 15 grip under the lower edges 19 of the U-profile pieces 18 and thus fix the profile frame to the side walls of the stacking container and increase its rigidity. Of course, such arrangements can also be provided in the side walls 3, 5.

According to a special embodiment, in the stacking container shown in Figures 7 to 11, the recesses 17 are extended in the outer walls in such a way that the U-profile pieces 18 on the outside run flush with the outer wall and are pressed inwards by the attached profile frame so that the retaining lugs 15 can grip under the lower edge 19 of the profile pieces 18 in a force-fitting manner.

Instead of the U-profile piece 18, any profile piece, for example a cuboid-shaped block or plate with a corresponding surface, can be used.
