PROBLEM TO BE SOLVED: To obtain a paper container in which a face part that can be manufactured by a conventional charger is formed in a corner part of a body part.SOLUTION: In a paper container of a gable roof type, a body part longitudinal folding line 4 forming one corner part out of body part longitudinal folding lines 1, 3, 4 forming corner parts of a cylindrical body part 10 is constituted of oblique folding line parts 36a, 36b, 37a, 37b, that are provided from each of vertexes 34, 35 on adjacent body part panels 5, 8 to make a prescribed angle with a virtual tangent line and to have a prescribed dimension when an upper part intersecting point where the virtual tangent line of the adjacent body part panels 5, 8 intersects vertex part lateral folding lines 11, 18 and a lower part intersecting point where the virtual tangent line intersects bottom part lateral folding lines 24, 29 are the vertexes 34, 35, and parallel longitudinal folding line parts 38a, 38b provided to connect end parts of the oblique folding line parts 36, 36b, 37a, 37b provided on the adjacent body part panels 5, 8 in a manner to oppose to each other in vertical direction. A face part 39 are formed not to be overlapped with a longitudinal edge joining part 40 joined by a longitudinal direction seal panel 9.SELECTED DRAWING: Figure 1 |
