PROBLEM TO BE SOLVED: To provide a paper-made container capable of reducing a size at a height direction in proportion to reduction of the contents of the container.SOLUTION: The paper-made container 10 has a side face section 20 formed by folding over a pasteboard at a square cylindrical shape, a bottom face section 30 welded and formed by folding one side of the side face section in a longitudinal direction, and a container top section 40 with a gabled roof-shape, wherein the contents are filled up in the inside, arranged on the other side and sealing inside by welding. The paper-made container 10 prepares crease-guiding lines 100 on the side face section 20 forming a height direction of the paper-made container 10, and can be reducible in the height direction by repeating folding-in (a broken line) and/or folding-back (a dotted line) of the crease-guiding lines 100. |
