PROBLEM TO BE SOLVED: To provide a nozzle structure of a bottle capable of definitely exerting a tamper evident function where the seal of an inner ring inside a cap is designed to be released after a tamper evident band is definitely fractured at the time of a container lid opening. SOLUTION: The nozzle structure of the bottle, wherein the thread starting point of a male thread on the external peripheral surface of the nozzle is formed below the seal point position of the inner ring on at least the inner peripheral surface of the nozzle, in a combination that the nozzle of a plastic-made bottle has the tamper evident characteristics and the container lid where the inner peripheral surface of the nozzle is sealed with the inner ring is spirally fitted. It is preferable that the distance between the thread starting point and the seal point of the inner ring is 0.4 mm≤Δh≤2.0 mm. COPYRIGHT: (C)2005,JPO&NCIPI
