Claims

[Scope of utility model registration request]

A stopper for a liquid container, which includes a seal part 2 that closes the opening of the container 1, a spout 3, a valve body 4 that opens and closes the spout 3, and a spring 5 that biases the valve body 4 in the valve closing direction. 4 is exposed at the open end of the spout 3, an outer protrusion 7 is provided on the outer surface of the valve body 4, and an inner protrusion 8 is provided on the lower surface of the valve body 4 inwardly from the outer protrusion 7, and these protrusions 7, 8 are set in a positional relationship in the circumferential direction without any gap or spaced apart by an integral multiple of the rotation pitch P of the valve body 4, and the upper guide portion 9 facing the outer protrusion 7 is placed on the lower surface of the stopper body 10. At the same time, a lower guide portion 11 facing the inner protrusion 8 is attached to the plug body 1.
0, the upper guide part 9 is formed by downward serrated projections 13 arranged annularly at a constant pitch, and the lower guide part 11 is arranged in an annular shape at a constant pitch by shifting the lower guide part 11 by half a pitch. A notch 15 is formed by upward serrated protrusions 14 arranged in a row, is recessed deeper than the trough of every other serrated protrusion 13 of the upper guide part 9, and has a width that allows the outer protrusion 7 to fit therein. A stopper for a liquid container characterized by being provided with.
