Claim:
A collapsible container consisting of a rigid polymeric material for the transport and storage of goods, which container includes a carrying base part, an upper frame member, a plurality of collapsible side walls and a lid which is supportable on said upper frame member, said side walls being movably attached to said base part by lower hinge members, said side walls being formed of a first and second side wall being arranged parallel to each other and a third and fourth side wall being arranged parallel to each other and adjacent to the first and second side walls, wherein said first and second side walls are movably attached at upper ends thereof to said upper frame member via upper hinge members, said first and second side wall each being parted into an upper and lower section, said upper and lower wall sections being connected so as to be foldable about a horizontal folding line, wherein an upper edge of said third and fourth side walls are each provided with at least one locking lip, said locking lips limiting the outward movement of said third and fourth side walls relative to the upper frame member by engagingly interacting with an inner edge of said upper frame member, said lid being provided with an inner rim, said inner rim engagingly interacting with said inner edge of said upper frame member, said lid member having external dimensions which are within the confines of said upper frame member, said inner rim furthermore cooperatively engaging with said locking lips thereby limiting inward movement of said third and fourth side walls while said lid is arranged on said collapsible container whereby undesired collapsing of said collapsible container is prevented while said lid is properly arranged on said container, said lid being provided with a plurality of spaced coupling hole members in at least two opposite edges of said lid, said plurality of coupling hole members being aligned with a corresponding plurality of rim coupling hole members spaced at the upper edge of the sidewalls of said upper frame member, a sealing pin being insertable through, respectively, each of said coupling hole members and said rim coupling hole members for locking said lid to said upper frame member, each said sealing pin being provided with snapping wedges and a maneuvering section for engaging the walls of said coupling and rim coupling hole members, and each said sealing pin being dimensioned to break at removal from the inserted position thereof extending through said rim coupling hole member and lid coupling hole member so as to render detectable any unauthorized tampering with said collapsible container.
