A container for containing cargoes to be transported by a ship or the like. Bendable right and left side plates and a vertically movable front shutter and back shutter are provided between a top plate and bottom plate so that, when the front shutter and back shutter are pulled up into the top plate and the right and left side plates are bent inward, the container will be compactly folded. Reinforcing devices are provided respectively between the top plate and right and left side plates and between the bottom plate and right and left side plates. Shutter locking devices for locking the shutters when they are pulled down are provided respectively between the front shutter and bottom plate and between the back shutter and bottom plate. Side plate locking devices are provided against the intermediate bending parts of the right and left side plates. A pair of springs energized normally to pull up the front shutter and back shutter are provided in the directions intersecting rectangularly with the shutter moving direction within the top plate. Thus, even if a load is applied from outside, the container will not be deformed. When each shutter is pulled down, it will be able to be locked. The extending and contracting stroke of the pair of springs can be taken to be sufficient.
