In a folding container assembled in a box form by raising folded long side walls 51 so as to stand perpendicular to a bottom portion 10 and then raising folded short side walls 27 so as to stand perpendicular to the bottom portion, each of the short side walls is composed of an upper short side wall portion 27a and a lower short side wall portion 27b, and horizontal pins h3 formed on the upper short side wall portion are inserted into corresponding slits 35 in hinge female blocks H3formed on the lower short side wall portion to hinge the upper short side wall portion and the lower short side wall portion together. The short side walls are each composed of the upper short side wall portion and lower short side wall portion connected together with hinge members to reduce the height of the folded folding container. Accordingly, the folded folding container can be more efficiently housed to save housing spaces.

What is claimed is: 1. A folding container assembled in a box form by raising folded long side walls to stand perpendicular to a bottom portion and then raising folded short side walls to stand perpendicular to the bottom portion, the folding container being characterized in that: the short side walls are each composed of an upper short side wall portion and a lower short side wall portion which are connected together via hinge members, said upper short side wall portions and said lower short side wall portions having equal widths, and, when said upper short side wall portions are rotated to extend upward in a plane with said lower short side wall portions, said short side walls extend higher than said long side walls, wherein said upper short side wall portion is arranged for overlapping said lower short side wall portion by being folded at said hinge member when said folding container is assembled in a box form, and the upper short side wall portion overlapping the lower short side wall portion is locked on the lower short side wall portion by lock means when said folding container is assembled in a box form, said container being further characterized in that inward-fall preventing protrusions are formed at an upper end of the lower short side wall portion, and similar inward-fall preventing protrusions are formed at a lower end of the upper short side wall portion so that when the upper short side wall portions of the folding container assembled in a box form are rotationally moved substantially through 180째 from a state in which the lower short side wall portion and the upper short side wall portion are placed on each other until the lower short side wall portion and the upper short side wall portion are substantially flush with each other, the inward-fall preventing protrusions formed at the lower end of said upper short side wall portion impact the corresponding inward-fall preventing protrusions protrusively formed at the upper end of the lower short side wall portion, thereby preventing said upper short side wall portion from rotatably moving inwardly of the folding container from a perpendicular state thereof. 2. A folding container assembled in a box form by raising folded long side walls to stand perpendicular to a bottom portion and then raising folded short side walls to stand perpendicular to the bottom portion, the folding container being characterized in that: the short side wails are each composed of an upper short side wall portion and a lower short side wall portion which are connected together via hinge members, said upper short side wall portion and said lower short side wall portion having equal widths, and, when said upper short side wall portions are rotated to extend upward in a plane with said lower short side wall portions, said short side walls extend higher than said long side walls, wherein said upper short side wall portion is arranged for overlapping said lower short side wall portion by being folded at said hinge member when said folding container is assembled in a box form, and the upper short side wall portion overlapping the lower short side wall portion is locked on the lower short side wall portion by lock means when said folding container is assembled in a box form, said container being further characterized in that the lock means is composed of fitting slots formed in the lower short side wall portion and engagingly-locking protruding pieces formed on the upper short side wall portion and which are fitted in the corresponding fitting slots, and inward-fall preventing protrusions are formed at an upper end of the lower short side wall portion, and similar inward-fall preventing protrusions are formed at a lower end of the upper short side wall portion so that when the upper short side wail portions of the folding container assembled in a box form are rotationally moved substantially through 180째 from a state in which the lower short side wall portion and the upper short side wall portion are placed on each other until the lower short side wall portion and the upper short side wail portion are substantially flush with each other, the inward-fall preventing protrusions formed at the lower end of said upper short side wall portion impact the corresponding inward-fall preventing protrusions protrusively formed at the upper end of the lower short side wall portion, thereby preventing said upper short side wall portion from rotatably moving inwardly of the folding container from a perpendicular state thereof.
