PROBLEM TO BE SOLVED: To facilitate separation of stacked paper containers, the invention relates to a paper container having a paper inner container and a paper outer cylinder, and a cylindrical body end bend device and a cylindrical body end bending method for bending an end of the paper cylindrical body, the bending processing is performed to the end edge of the paper cylindrical body and the separation of stacked paper containers which use cylindrical bodies to which the bending processing has been performed is facilitated.SOLUTION: A blade 80 having an end 82 and a stand 83 standing from the end rotates relatively to a cylindrical body. And an end part of the cylindrical body is pressed to the end 82 aslant so that an obtuse angle &thetas; is formed on the stand 83 side. |
