Abstract: A foldable transportation container comprises a container body formed into a box having a rectangular bottom, and a pair of first side walls and a pair of second side walls provided along the periphery of the bottom wall, rotating means provided on the lower ends of the side walls so that the side walls can be folded inward of the container body, an engagement member provided on the outside face of the first side wall. Engagement portions are provided on both ends of each second side wall. The first side walls are folded onto the upper face of the bottom wall and then the second side walls are folded onto the first side walls. An operation portion is provided at the substantial center of each engagement member. Engagement projections are provided at the ends of each engagement member. The engagement portions are engaged with the engagement projections to limit inward rotation of the first side walls.
