摘要： PROBLEM TO BE SOLVED: To prevent foods from being leaked or flowing out from four corners of a rectangular container formed of a cardboard and a synthetic resin film without using any mold frame and an injection molded container.SOLUTION: A method for manufacturing a packaging container includes: continuously forming side walls at a bottom surface and its four side edges with a single layer paper or a waterproof surface cardboard; forming protruding pieces that form second side walls at both right and left ends of opposing two of the four side walls; continuously forming a lid piece at the upper edges of the side walls through folding lines; cutting the inner surface of a punched-out base sheet (A) with margins protruded to the outside in a substantially triangle shape from clearances of four corners of the adjoining side walls when they are raised, to form a single-layer or laminated synthetic resin film 8; bonding the film by thermo-pressing or adhesive agent at arbitrary locations of the bottom surface and each of the side wall surfaces and at the upper end root portions; raising the side walls to form a rectangular-shape and covering the inner wall surfaces with the single-layer or laminated synthetic resin film 8.
