PROBLEM TO BE SOLVED: To provide a leg at a rear part of a paper box container to make a rear high and a front low to obtain a box which is convenient to display, easy to assemble and durable by folding up a leg plate connected to a bottom plate via a fold from the bottom plate and a side plate. SOLUTION: A leg plate 12 folded up from a bottom plate 1 and a side plate 4 is connected to the bottom plate 1 via a fold 12a. A protrusion 13 is provided at an end on a side of the side plate 4 of the leg plate 12 to open a hole part 1a along a fold (c). At the time of assembly, the leg plate 12 is folded up outward at a right angle from the bottom plate 1 and folded via the fold (c) at a right angle, and then the protrusion 12a at the end of the leg plate 12 is fitted into the hole part 1a and locked. A lower face of the leg plate 12 is set at an angle ofθ1 with respect to the fold 12a. Thus a gradient angle between the bottom plate 1 and a flat base isθ1 at the time of mounting.
