A moving mechanism that opens and closes the opening end by moving the body toward and away from the opening end, and defines an outer periphery of an annular wall part that defines an internal flow path of the internal plug. Attaching / detaching to / from the inner periphery of the outer stopper so as to form a liquid passage space for communicating the inner passage of the inner stopper with the outside between the inner peripheral surface of the outer stopper and the outer peripheral surface of the inner stopper. It is characterized in that the inner stopper and the outer stopper are integrated by being joined as much as possible. .

[0007]

[Action]

 According to the stopper of the liquid container of the present invention, the external stopper and the internal stopper are formed by screwing, for example, the internal thread formed on the internal stopper to the internal thread formed on the external stopper. In addition to being detachably integrated, a liquid flow path communicating between the internal flow path provided in the internal plug and the outside is formed between the external plug and the internal plug.

In this state, when the push button is pressed, the valve body is moved in the approaching / separating direction with respect to the open end of the internal flow path. Here, when the valve body is moved in the direction close to the opening end, the opening end of the internal flow path is blocked by the valve body, and the outflow of the internal solution in the container body is prohibited. When the valve body is moved away from the open end, the closed state of the open end of the internal flow path by this valve body is released and the valve body is opened, and the internal flow path and the liquid flow from the open end. The internal solution in the container body can flow out to the outside via the flow path.

Further, since the outer stopper and the inner stopper are detachably coupled, for example, by screwing, the inner stopper is separated from the outer stopper by loosening the coupling, and the outer stopper forming the liquid flow path is formed. The inner peripheral surface and the outer peripheral surface of the internal plug can be easily cleaned.
