PROBLEM TO BE SOLVED: To facilitate the classifying disposal and recovery by smoothly and easily removing a plastic spout which is integratedly and firmly fitted and fixed to a mouth part of a glass bottle body by a plugging method from the bottle body. SOLUTION: A plastic spout for classifying recovery which is easily removed from a mouth part B1 of a bottle body B by separating a part closely attached to an external circumferential surface of the mouth part is provided with an outer cylindrical part 1 closely attached to the outer circumferential surface side of the mouth part of the bottle body, an inner cylindrical part 3 closely attached to the inner circumferential part side, an upper surface part 2 to connect the outer cylindrical part 1 to the inner cylindrical part 3, and thin-walled parts 11, 12, 13 for separation which are continuous to an inner surface of the outer cylindrical part 1, the upper surface part 2, and the inner cylindrical part 3, and a pull-tab 5 for pilferage to separate the outer cylindrical part is provided on the outer circumference of the outer circumferential part 1 corresponding to a separation-state side end part of the thin-walled parts for separation. |
