摘要

The storage box stacking structure has a number of support elements (2) provided symmetrically on two opposite lying side wall surfaces of each box (1), by which the storage boxes are supported in a stack. The support elements are curved in construction and are fitted on the upper edge of one of the side wall surfaces of one of the storage boxes. The support elements have a stepped cross section and from the two opposite lying vertical side wall surfaces of each box extend, downwards, then upwards and finally downwards.
