PROBLEM TO BE SOLVED: To provide a case for article transportation which is made of a plastic corrugated cardboard and can prevent access to a stored article from the outside during transportation.SOLUTION: A plastic corrugated cardboard is formed by heating and then folding a side-part protrusion piece 33 on a lid body 3 composed of a plate of a plastic corrugated cardboard and attaching a connection part 31 of the lid body 3 to a box body 2 with machine screws so that an opening of the lid body 3 is freely openable and closable. The configuration prevents deflection of the lid part 30 due to the side-part protrusion piece 33 although the lid body 3 is composed of a flexible plastic corrugated cardboard and thereby inhibits peeping or taking out the stored contents. |
