The invention relates to a pallet container, which consists of a | Container is formed, of upright tabular walls and | has a hexagonal or octagonal cross-section, on | is placed a pallet and provided with a \ from a tabular surface of cardboard such as corrugated cardboard or solid cardboard, the lid prepared, whose peripheral parts are folded down at right angles to form cover edge portions which are adjacent to the walls of the container.

A pallet container of the type indicated above is known from the Dutch Pa-fcaivfcaimiaia-ang 7 414 833, among others. These describes a pallet container, which is formed from a container with a polygonal, in particular octagonal, cross-section has cardboard panels and is inserted within a sleeve made of cardboard panels with a number of them being extended downwards and attached to the sides of the pallet. the

The container is closed at its head end with a lid, which is made of a Pcippf pool by cutting and folding will be produced. The lids, which are generally used to this day for pallet containers, are made from a plate-shaped one Flat cardboard, such as corrugated cardboard or solid cardboard, is made and is equipped with peripheral incisions and folding edges.

The blank formed in this way is notched at its corners so that the resulting free parts over the folded edges can be bent inside to form edge pieces of the lid. In general, these edge pieces are connected, by wrapping one or more strips of tape around them.

For a container formed from a container with an octagonal cross-section, the lid is made from a square area, the sides of which have a dimension equal to the outer width of the container, measured across the walls, enlarged by twice the height of the desired lid edge pieces. For one octagonal pallet container with a common width of 110 cm, a lid area is used that is about 140 cm Measures χ 140 cm so that the edge pieces of the lid will be about 15 cm high. The corners of the square face are under an "angle of 45 ° cut off what in itself, a material loss implies. The eight corners of the base surface are notched to cut free the edge pieces laterally, which then can be bent over the previously provided folding edges.

These lids not only have the disadvantage that their production is therefore associated with a loss of material and requires many operations, but it is also necessary to choose a cardboard for these lids that has a relatively low puncture resistance, as is the case with corrugated cardboard of a thickness of less ails 4 mm and at a fixed cardboard having the weight per unit area of less than 1000 g / m, because the cutting of the corners \ J from a tabular Pappfläche a high piercing resistance and particularly their exact features represent costly with incisions operations encounter difficulties in the cardboard industry. In current practice, it is particularly found that the cutting and punching of corrugated pallets with a thickness of more than 4 mm results in the knives quickly becoming blunt, so that they often have to be replaced. Heavy punching machines are also used in order to obtain a high accuracy of the cuts. This disadvantage is particularly encountered when the cover the use of so-called double-o ■ double or dreifachwändiger corrugated cardboard or solid cardboard of a weight r> ro unit area of greater than 1000 g / m is required.

As a result, it is common to use a lighter grade of paperboard. Of course, this leads to lids that are often inadequate are resistant to the high stresses to which they are exposed during transport and storage are. For example, it is common practice to stack the pallet containers during transport and storage, usually in several layers so that the lid takes the weight

of the pallet above. In this case, there is a likelihood that lids made of corrugated cardboard of thinner than 4 mm or made of sturdy cardboard of light-

more than 100 g / m were produced, can be damaged. Damage to the lid can then quickly lead to damage to the container and often also to its contents. It also happens that the container stacked on top falls down from the one below as a result of the lid flexing when it is made of relatively weak cardboard.

It is often inevitable for containers that personnel walk or stand on them, e.g. during loading and Unloading of ship spaces and if they need to be covered in the case of storage in the open air. Under these circumstances it is often found that the lids collapse very frequently under excessive local loads. However, would be under In such conditions, the use of a heavier material, e.g. corrugated cardboard thicker than 4 mm or a solid one

Cardboard heavier than LOGO g / m , may be undesirable because of the high production costs, as this as a result of the punching operation

The present invention has the object of a To provide pallet containers with a lid that no longer has the disadvantages mentioned above. In particular a heavy and consequently strong cardboard quality can be selected for the lid without the need to perform expensive cutting operations. The invention
