Abstract
Contour of a storage section of a three-sided bag is formed of (1) two side inner lines in a longitudinal direction, (2) two tilt inner lines which tilt inside with forming an obtuse angle with each side inner line from a lower end of each side inner line, and (3) one lower side inner line in a lateral direction which connects lower ends of respective tilt inner lines. A longitudinal size “a” of an intersection IPa of the side inner line and tilt inner line on the basis of an intersection BP of a side outer line or its extension, and a lower side outer line or its extension is preferably within a range of 0.08 A to 0.71 A, and a lateral size “b” of an intersection IPb of the tilt inner line and lower side inner line on the basis of an intersection BP is preferably within a range of 0.12 B to 0.48 B.
Claims12
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 0.08 A to 0.71 A, and lateral sizes “b” of the intersections IPb on the basis of the intersections BP are within a range of 0.12 B to 0.48 B.
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 first 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, two second tilt inner lines which tilt inside with forming an obtuse angle with each of the first tilt inner lines from lower ends of the first tilt inner lines, and one lower side inner line in a lateral direction which connects lower ends of the second 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 first tilt inner lines be IPa, letting intersections of the second tilt inner lines and the lower side inner line be IPb, and letting intersections of the first tilt inner lines and the second tilt inner lines be IPc,
- longitudinal sizes “a” of the intersections IPa on the basis of the intersections BP are within a range of 0.08 A to 0.71 A, and lateral sizes “b” of the intersections IPb on the basis of the intersections BP are within a range of 0.12 B to 0.48 B;
- and
- the intersections IPc are located close to the intersections BP rather than a straight line which connects the intersections IPa and the intersections IPb, and longitudinal sizes “a1” of the intersections IPc on the basis of the intersections BP are within a range of 0.01 A to 0.70 A and lateral sizes “b1” of the intersections IPc on the basis of the intersections BP are within a range of 0.01 B to 0.47 B.
