ABSTRACT:
Packing container made of foldable packaging material, especially cardboard.
The packing container consists of two parts, namely a container-like base part (10), open at the top, and a covering part (11) which can be placed on same. The base part (10) forms folds, namely folding units (30, 31) in the region of end walls (17, 18). Cover flaps (20, 21) of the upper covering part (11) enter the folding units in such a way that the folds of the end wall (17, 18) are fixed in the folded position by the insertion tabs (20, 21). Pulling out the insertion tabs (20, 21) frees the folds and thus the base part (10) can be shaped into a flat position.
