PROBLEM TO BE SOLVED: To reduce unit consumption of an expensive soft elastic material and increase design flexibility by enabling a discharge valve with a slit valve structure to exhibit a high non-return function while maintaining the discharge valve to retain a normal wall thickness and shape of a conventional slit valve.SOLUTION: In a delamination bottle-shaped capped container storing a viscous content N, the discharge valve 23 has the slit valve structure, and a suppression part 27 applying suppressing action to flowing of the content N is located near the inner side of the discharge valve 23. With reduced pressure generated within a container body 1, the content N located near the inner side of the discharge valve 23 is turned into a state that is difficult to flow, so as to securely inhibit intrusion of outside air from the discharge valve 23 having the slit valve structure. |
