PROBLEM TO BE SOLVED: To provide a foldable container in which engagement force between a bottom wall and flip-up side walls can be stabilized.SOLUTION: According to a foldable container 10 of the present invention, flip-up side walls 30 rotatably connected to an upper frame 20 are hung down from the upper frame 20 to be engaged with a bottom wall 11 in an assembled state and are folded inward in a folded state. The bottom wall 11 and flip-up side walls 30 are provided with locking projection parts 14 and side-wall side locking parts 50 which, in the assembled state, are butted together in the width directions of the flip-up side walls 30, and which are locked to each other to inhibit the flip-up side walls 30 from being folded inward. Each side-wall side locking part 50 includes an elastic extension/contraction part 52 which is projected from an opposite support wall 41 facing the locking projection part 14 in the width direction of the flip-up side wall 30, and which is extended and contracted in the width direction of the flip-up side wall 30 by elastic deformation.SELECTED DRAWING: Figure 9 |
