PROBLEM TO BE SOLVED: To enable paper containers to be stacked without being unfastened and shifted by forming a standing piece on an inner peripheral rim on an upper face of a coupling bond which integrally couples a container body with a lid and by locking the standing piece of the coupling band of one of the paper containers with a lower end curl of a body of a paper container stacked upward. SOLUTION: The paper container 1 has a container body 4 made of a paper material comprising a cylindrical body 2 and a bottom plate 3, while an upper opening of the container body 4 is closed by a lid 5. Both upper and lower ends of the body are formed to be curls 2a, 2b while metallic reinforcing rings 6, 7 are attached along the upper and lower curs 2a, 2b and neckings 2c, 2d. Then a coupling bond 8A is wound over a recess 6a of the upper reinforcing ring 6 corresponding to the necking 2c, wherein an inner peripheral rim of the coupling band 8A in contact with an upper face of the lid 5 is formed to be a standing piece 81. Thus at the time of stacking the containers, the lower curl 2b of an upper stage container 1 is locked with the standing piece 81 to prevent the containers from being unfastened and shifted. |
