The above-mentioned conventional spout plug is opened and closed by rotating the handle in both forward and reverse directions. Therefore, when another object accidentally comes into contact with the handle and is rotated, the plug is closed. The stopper in the state is opened, and the contained liquid will inadvertently flow out.

According to the first aspect of the present invention, the handle is inadvertently rotated by projecting the handle above the nozzle and inserting the front portion of the handle between a pair of left and right sandwiching plates standing upright from the upper surface of the palate. This is provided so that this can be reliably and easily prevented.

According to a second aspect of the present invention, in addition to the object of the first aspect, when the palate is formed of a soft synthetic resin material in order to improve the sealing performance when the nozzle is fitted, the holding plate is easily elastically deformed. As it becomes easier for the handle to come off between the sandwich plates,
By vertically installing a flange-shaped reinforcing plate at the rear edge of the sandwiching plate, the sandwiching plate is provided so as to prevent elastic deformation of the sandwiching plate.
