Abstract:
1. A storage bag which is a flat bag type storage bag including a three-sided bag, a twofold bag, and a two-sided bag; the storage bag having a predetermined whole longitudinal size, a predetermined whole lateral size, and a storage section with an upper opening; comprising: a contour of the storage section being formed of two side inner lines in a longitudinal direction, two tilt inner lines which tilt inside with forming an obtuse angle with each of the side inner lines from lower ends of the side inner lines, and one lower side inner line in a lateral direction which connects lower ends of the tilt inner lines; wherein with letting the whole longitudinal size be “A”, letting the whole lateral size be “B”, letting intersections of two side outer lines or their extensions, and a lower side outer line or its extension be BP, letting intersections of the side inner lines and the tilt inner lines be IPa, and letting intersections of the tilt inner lines and the lower side inner line be IPb, longitudinal sizes “a” of the intersections IPa on the basis of the intersections BP are within a range of 0.08A to 0.71A, and lateral sizes “b” of the intersections IPb on the basis of the intersections BP are within a range of 0.12B to 0.48B.
