[Means for Solving the Problems] A short tubular portion stands up from an upper end of a base tubular portion formed to be watertightly fitted into a neck portion of a container main body, and the upper and lower ends of the short tubular portion communicate with the inside of the short tubular portion. A stopper main body provided with a support cylinder portion having openings at both end surfaces and a middle portion of the nozzle are rotatably and watertightly fitted to the inner surface of the support cylinder portion, and a handle is projected laterally from the outer surface of the rear end portion of the nozzle. The rotating member, the palate that is fitted to the outer surface of the front portion of the nozzle in a watertight manner, and the elastic band portion that projects from the outer surface of the rear portion of the palate and that has the rear end joined to the outer surface of the rear portion of the rotating member. When the nozzle is rotated with respect to the support cylinder with the palate removed, the liquid pouring plug in which the through hole communicating with the upper surface opening of the short cylinder is formed in the nozzle, 3 at the rear portion and the front end portion of the support tubular portion 14 are provided with irregularities for preventing rotation of the palate 3 with respect to the support tubular portion. The engagement means and the fitting surface between the nozzle 21 front and palate 3, the second engagement means of irregularities for preventing rotation of the nozzle 21 relative to the mouth lid, were formed.

[0006]

In the plug closed state shown in FIG. 1, the palate 3 and the plug body 1
The rotation of the palate 3 with respect to the support tubular portion 14 is prevented by the first engaging means provided at the front end portion of the support tubular portion 14, and the second engagement provided on the fitting surface between the palate and the front portion of the nozzle 21. Since the means are engaged with each other, the nozzle 21 cannot be rotated with respect to the palate 3, and therefore the handle 23 cannot be rotated to open the stopper.

In the above state, when the palate 3 is removed from the front portion of the nozzle 21, the nozzle 21 can be rotated by using the handle 23, and the through hole 22 of the nozzle and the upper surface of the short tube portion 13 of the plug body 1 can be rotated. The opening communicates and opens.

In the liquid pouring stopper of the present invention, the base cylinder portion 11 of the stopper body 1 is watertightly fitted to the neck portion of the container body, and the container body is placed on, for example, a table so that the front end of the nozzle 21 faces downward.
