<p>A method of manufacturing a paper packaging container and the paper packaging container; the method, comprising the steps of forming a packaging material in a tube shape by folding through vertical pleat lines, filling liquid food into the tube-shaped packaging material, forming the tube-shaped packaging material into a primary-shaped container by folding through lateral pleate lines in transverse direction, and folding the primary-shaped container along the pleat lines so as to form the container into a final shape, characterized in that a folding piece (8) formed by shaping a top part is folded onto a side wall surface (3b), and the top part (4a1) is formed in a shed roof-shape, whereby the paper packaging container allowing a wide and tall filling-out device to be installed thereon, subjected to a low stress, and less in cracking can be provided at a high speed.</p> |
