PROBLEM TO BE SOLVED: To provide a paper container manufactured so as to be easily opened which can be surely opened and has a good appearance by solving the problem that a cleavage of paper easily diverges in manufacture capably of being easily opened by conventional half cutting of the front and rear surfaces.SOLUTION: A paper container has coating film layers formed on the front and rear surfaces of a paper layer, and can be opened along a cut line. The cut line has a surface half cut line that reaches the paper layer through a surface film layer, and a rear half cut line parallel with the surface half cut line and reaching the paper layer through a rear film layer. A plurality of rear half cut auxiliary lines are formed diagonally rearward on the opposite side of the surface half cut line from the rear half cut line with respect to the opening direction, and reaching the paper layer through the rear film layer. |
