<P>PROBLEM TO BE SOLVED: To provide a folding container excellent in ease of work of folding operation and assembling operation than before. <P>SOLUTION: In the container 10, a plurality of reinforcing vertical ribs 47 are extended for reinforcement from a plurality of side surface partition walls 48 arranged on the inner surface of each flip-up side wall 40 to the lower end of the inner surface of each flip-up side wall 40, thereby eliminating a conventional reinforcing rib extended vertically in a part below an intermediate part of the outer surface of the flip-up side wall 40. Moreover, a middle stage groove shape reinforcing part 43 crossing the plurality of side surface partition walls 48 is arranged on the inner surface of the flip-up side wall 40, thereby eliminating also a conventional reinforcing rib extended horizontally in the intermediate part of the outer surface of the flip-up side wall 40. Thus, a problem of biting to a hand of the reinforcing rib of the outer surface in the flip-up side wall 40 can be prevented, and the ease of work of the folding operation is enhanced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
