To provide a tubular paper container highly practical as a paper container for a high functional liquid body, which container is free from crack or delamination, etc. even when a stress such as a tension or a shock is applied to the four corners of the container in processing the container, is provided with a long lasting gas barrier characteristic even when a content is stored for a long time, is excellent in rigidity and drop strength and is easily disposed of after use.
A laminate is used as a material of a lid body 2, a bottom body 3 and a body part 1 constituting the container, and the laminate comprises a paper layer having a heat-seal layer on the surface thereof as a substrate. At least a vapor deposition film comprising an inorganic oxide is disposed as a gas barrier material inside the substrate, and a heat seal layer is provided inside of the gas barrier material. The tubular paper container comprises the body part 1 made by applying an edge protecting work to the laminate and forming the laminate into a tube and the lid bod 2 and the bottom body. The four corners of the container are rounded to a radius of 10 mm.
