PROBLEM TO BE SOLVED: To prevent the alteration by forming a folding pleat section cut into the form of overlapping block lines on the outer peripheral wall on the opening side of a cylindrical container, outer fitting a paper cylindrical cover on the outer periphery of the folding pleat section and bonding and fixing the same thereon. SOLUTION: Overlapping folding pleat section 3 is formed on a peripheral wall 2 on the opening side of a paper cylindrical container 1. Broken lines 4 for cutting and removing are cut on the folding pleat section 3, and a paper cylindrical cover 5 is outer fitted on the outer periphery of the folding pleat section 3, and the paper cylindrical cover 5 is bonded and fixed on the folding pleat section 3. When the container is unsealed, the folding pleat section 3 is released from the paper cylindrical container 1 by rotating the paper cylindrical cover 5 and overlapped inside the paper cylindrical cover 5, and the paper cylindrical cover 5 can be fitted thereon removably. In the above constitution, a food is stored and then the paper cylindrical cover 5 is fitted and fixed on the folding pleat section 3 by a bonding agent 10 while the cover is fitted thereon to prevent the alteration. |
