PAPER CAN CONTAINER

PROBLEM TO BE SOLVED: To easily manufacture a paper can container while reducing cost by simplifying a manufacturing process.SOLUTION: A paper can container 1 includes: a body part 21 formed of a cut-tear line except for a crease f of a setup length in the right and left direction of an upper end; a cylindrical body 2A formed by attaching a circumferential wall part continuously arranged to the body part 21 and having substantially half width of the body part 21, and also comprising a guide part 22 of the setup height having an upper end edge projecting upward beyond the cut-tear line, while cylindrically winding the guide part 22 along the inner circumferential surface of the body part 21; a top surface plate 3 attached to a curling part of the cylindrical body 2A; and a bottom plate sandwiched and attached to a folding part of the cylindrical body 2A. Then, the cylindrical body 2A is cut-and-torn along the cut-tear line and divided into an upper edge portion and a lower portion, and the upper edge portion is turned centering on the crease f with respect to the lower portion, and thereby is engaged and disengaged to/from the guide part 22 disposed substantially for a semicircle in the inner circumferential surface of the lower portion to open and close the opening of the lower portion.
