An
assembly (102) of collapsible intermodal shipping containers (100), each container (100) being configurable between a collapsed configuration and an expanded configuration, and each container (100) including: opposing first and second elongate side walls (120, 140), each having lower and upper opposing sides (120a, 120b, 140a, 140b); an elongate floor (180) extending between the lower sides (120b, 140b) of the side walls (120, 140) in the expanded configuration; an elongate roof (160) extending between the upper sides (120a, 140a) of the side walls (120, 140) in the expanded configuration; and at least one end frame (240) to close an opening (104) created by the side walls (120, 140), floor (180), and roof (160), in the expanded configuration, the end frame (240) having a corner
casting (280), wherein the floor (180) and roof (160) abut the end frame (240) in the expanded position at a
mating surface (166), and include: one or more locating stubs (300) on the
mating surface (166), the end frame (240) having one or more receivers (242) for receiving the locating stubs (300), wherein the receivers (242) are shaped to conform to the locating stub (300); and a locking stub (322) engageable with the corner
casting (280) when the end frame (240) closes the opening (104) and movable between a free position and a locking position, wherein the
assembly (102) includes: a first container (100a), having the features defined above and configured in the collapsed configuration; a last container (100c), having the features defined above and configured in the collapsed configuration; and at least one intermediate container (100b), having the features defined above and configured in the collapsed configuration, wherein the receivers (242) of the end frame (240) of the first container (100a) receive the locking stubs (322) of the first (100a), intermediate (100b), and last container (100c), such that the intermediate (100b) and last containers (100c) are connected to the first container (100a).
