At the side surface, an acute angle portion 20 is formed upward from the lower end portion 19, and an inner acute angle portion 21 is formed at the end point 18 so as to face inward in the radial direction. Reference numeral 6 denotes a lid, which is made of synthetic resin, and has a cap 14 composed of a top portion 7 and a tubular portion 8 and a locking ring 15 integrally formed on the lower portion thereof with a weakening line 9 in the circumferential direction. An upper thread 10 and a lower thread 11 are continuously formed on the inner surfaces of the cap 14 and the locking ring 15. The upper and lower screw threads 10 and 11 are in pressure contact with the lower portion of the screw thread 3 through a play 16. The lower thread 11 has a lower end portion with a hook portion 12 that is hooked to the lock portion 4.
Are formed. The hooking portion 12 is formed in a shape that matches the acute angle portion 20 and has a convex portion 13 that meshes with the inner acute angle portion 12, and is locked when the lid body 6 is rotated in the screwing direction. However, when the lid 6 is still rotated in the screwing direction, the weakening line 4 is torn. As a result, the illegal opening is found, and the normal opening can be performed.
