PROBLEM TO BE SOLVED: To open a cap easily while securing sealing properties. SOLUTION: Locking protruded lines 10 to be locked to a jaw section to be locked formed on the outer peripheral face of a container opening are formed on the inner peripheral face of a skirt wall 6 suspended from the periphery of a top face wall, and a tab 12 is formed on the outer peripheral face on the opening end of the skirt wall 6. When the protruded locking lines 10 are engaged with the jaw section to be locked, the locking depth in the radius direction of protruded locking lines 10 formed on both side areas of the tab 12 to the body section to be locked is formed to be less than respective locking depths of the protruded locking lines 10 formed on other peripheral areas. |
