た。However, the above-mentioned conventional cap with an inner sealing ring is provided with an outer peripheral surface of the inner sealing ring and a bottle opening in order to prevent leakage of contents and intrusion of various bacteria into the bottle. If the tightness with the upper inner peripheral surface of the neck is strengthened and the sealing of the bottle is improved, a large tightening torque force is required when screwing the cap onto the mouth and neck of the bottle and mounting it, When used by consumers, the cap was sometimes difficult to open. Furthermore, when the tip of the inner sealing ring hits the top surface of the neck and neck of the bottle, the rigidity of the inner sealing ring attached the bottle to the neck of the bottle in an oblique state and caused liquid leakage. .
