PROBLEM TO BE SOLVED: To improve evidence of being unsealed. SOLUTION: A bridge piece is formed as a rectangular plate, an upper top is connected with a lower end periphery of a cap body, and a lower top is connected with an upper end periphery of an annular band. Thus, when the cap is closed, the bridge piece tilts approximately by 45 degrees so that an upper side of the bridge piece comes into contact with the lower end periphery of the cap body and a lower side of the bridge piece comes into contact with the upper end periphery of the annular band. When the cap is once opened, the bridge piece is pulled up to stand, and in addition the annular band separates downwardly from a lock receiving piece of a container mouth due to its own weight.
