At the same time, the protrusion 47 at the lower end of the side wall 41 of the intermediate member C engages with the locking protrusion 26 of the inner plug B, and the setting with the inner plug B of the intermediate member C is completed.
Since the setting of the intermediate member C on the inner plug B is smaller than that of the screw cap D, the center position can be easily found, and the side wall 41 makes it easy to set. Will not break.

After the intermediate member C and the inner plug B are set, the mounting portion 4 of the inner plug B is applied to the mouth portion 1 of the container body A filled with the contents to be plugged.
After that, the screw cap D is attached to the inner plug B by tapping.
To attach the screw cap D, place the screw cap D on the upper surface of the intermediate member C set in the inner plug B, and push the screw cap D while slightly rotating it. As shown in FIG. The lower end of the female screw 65 of the screw cylinder portion 62 of the screw cap D abuts on the upper end of the male screw 23 of the inner plug B, and the screw cap D is fitted to the fitting outer tooth 55 of the engaging portion 54 of the intermediate member C.

Then, the rotational force of the screw cap D is easily transmitted to the plug body 15 via the internal teeth 51 and the external teeth 18, and a force for pulling up the plug body 15 upward is generated with the rotation of both screws.
As the rotation of the screw cap D progresses, the thinning weakening portion 14 finally breaks due to the rotational force and the pulling force applied to the plug body 15, and the spout is opened in the pouring cylinder 10 and separated from the pouring cylinder 10. The stopper body 15 is pulled up by the engaging portion 42 engaged with the tubular wall 16, and rises together with the intermediate member C and the screw cap D.

Further, when the female screw 65 is screwed off from the male screw 23 and the screw cap D is separated from the inner plug B, the contents in the container body A are opened through the opening of the dispensing cylinder 10 from which the plug body 15 is removed together with the screw cap D. Can be poured out. When the inner plug B is detached, the inner plug B is moved to the screw cap D side and remains in a held state.
