Collapsible container (1) for transport and storage of goods, which container includes a carrying base part (20), a plurality of collapsible side walls (30) and a lid (40). The side walls (30) are movably attached to said base part (20) by lower hinge members (31), said side walls (30) being arranged as a first and a second side wall (31 and 32 respectively) being arranged parallel to each other and a third and a fourth side wall (33 and 34 respectively) being arranged parallel to each other and adjacent to the first and the second side walls (31 and 32 respectively). The first and second side walls are moveably attached to an upper frame member (50) via upper hinge members (35) The first and second side wall (31 and 32 respectively) are further parted into each an upper and a lower section via a vertical folding line (36). An upper edge of said third and fourth side walls (33 and 34 respectively) are each provided with at least one locking lip (37), said locking lips (37) limiting the outwards movement of said third and fourth side walls (33 and 34 respectively) by interacting with an inner edge (51) of said upper frame member (50). The lid (40) is provided with an inner rim (41) which is interacting with said inner edge (51) of said upper frame member (50). The inner rim (41) is furthermore interacting with said locking lips (37) thereby limiting inwards movement of said third and fourth side walls (33 and 34 respectively) while said lid (40) is arranged on said collapsible container (1) whereby undesired collapsing of said collapsible container (1) is prevented while said lid (40) is properly arranged on said container (1).
