ABSTRACT:
This invention relates to a collapsible container comprising a bottom unit (1:1'), four angle posts (7:7'), two longitudinal side walls, two end walls (11:11') and an upper unit (12:12') supported by the end walls (11:11').
The reason for the container being made collapsible is to make it possible to place a number of folded-up containers in an unfolded container of the same kind at so-called return freight.
What characterizes the container of the invention is that the side doors (8:8') forming the side alls are collapsible to packages, which are pivotable relative to the angle posts (7:7'). Moreover, the angle posts (7:7') with intermediate end wall (11:11') are pivotable relative to the bottom unit, the folded-up container having such dimensions that there is room for it in an unfolded container of the same type.
