PROBLEM TO BE SOLVED: To restrain air from making an entry into a container, by making a shoulder part of the flexible container easily crushable to make contents easily extrudable.SOLUTION: A flexible container 1 includes a body 1A, a mouth/neck part 1C thinner than the body 1A, and a shoulder part 1B between the body 1A and the mouth/neck part 1C. The shoulder part 1B, the axial height (B) of which is in the range of 0.5A-0.7A with respect to a diameter (A) of the body 1A, has a continuous curved surface with a curvature radius (C) of 0.9A-1.2A toward the mouth/neck part 1C from the body 1A, and has a dome-shaped part 20, the upper end diameter (D) of which is in the range of 0.5A-0.7A. |
