Abstract

Abstract The present invention relates to collapsible side walls for a packing case, consisting of four wall sections hinged together at the side edges. The side walls are primarily intended to be used in connection with a cover and a bottom, for packing goods, e.g. bulk freight or small single items, which are to be transported on pallets. Each wall section consists of two facing plates being mutually spaced by means of parallel, mutually spaced ribs. The hinge at the side edges of each wall section is formed from a strip of pliable material whose longitudinal edges are secured in the slot between the plates of the wall sections.
