て、栓本体の全高を小さくできて、嵩高とならない。Further, since the valve body is operated by sliding the operation member in the radial direction, the valve body is operated by operating the operation member in the axial direction (up and down direction) of the plug body. In comparison, the height of the operation member itself and the space above and below the operation member can be reduced. Therefore, the overall height of the plug main body can be reduced, and it does not become bulky.

とならずにすむ。The outer dimension of the body from the head to the bottom of the stopper body is formed sufficiently smaller than the inner dimension of the mouth of the liquid container, and the vertical gap between the outer open ends of the annular gap is determined by the stopper. If the height is set to 15 to 30% of the total height of the main body, the liquid injection path at the portion corresponding to the annular gap portion can be made large, so that the liquid can flow out smoothly and the portion can be easily cleaned. Moreover,
Since the operation member is configured to be slid in the radial direction, the overall height of the plug body does not need to be large even if the vertical gap of the annular gap is made large.

Therefore, the appearance is smart, and there is no possibility that the distal end portion 30 of the operation member 15 hits another object, hand, or the like, and it is possible to prevent the valve from being closed without permission. That is, the valve is always closed when the lid 3 is closed.
