PROBLEM TO BE SOLVED: To provide a method for processing a paper container with a stack line so that stacked containers become a constant and stable stacked state without being brought to a adhesion state and the up and down dimension (stack height) of a predetermined number of stacked containers become constant and the stable supply or high speed automatic supply of the container to a filling machine becomes possible, and the paper container with the stack line. SOLUTION: A female mold member, which has a recessed groove part formed to the surface, which has the same shape as the outer surface of the side wall of the container, thereof, and a male mold member, which has a projected part having fitting relation with respect to the recessed groove part, are used and the container is held so that the surface of the female mold member and the outer peripheral surface of the side wall of the container are brought to a close contact state and pressed so that the projected part of the male mold member is fitted in the recessed groove part of the female mold member to form the stack line to the container at a predetermined position from the flange of the container so as to become parallel to the flange. |
