向の負荷を受けることはない。As described above, the length between the upper end and the lower end of the elastic piece projection 22b is longer than the distance between the top surface member projection 21c bottom surface 21d and the internal plug projection 17a top surface 17c in the valve closed state. Since the elastic piece projection 22b is located between the bottom surface 21d of the top surface member projection 21c and the top surface 17c of the internal plug projection 17a in the valve open state, the top surface member projection 21c is elastic. It is supported by the one-sided protrusion 22b and is fixed at a position above the valve closed state. Further, the lower end of the elastic piece projection 22b and the upper end 22d of the elastic piece locking claw 22a are
Since the distance between the elastic piece 22 and the inner plug projection 17a is substantially equal to or more than the vertical thickness of the inner plug projection 17a, the elastic piece 22 is not affected by the load in the inner diameter direction when the valve is open. I will not receive it.

Since the dimensions are set so that the position of the inner surface 14a of the cup when the cup 14 is attached is lower than the height of the top surface of the top member 21 in the valve open state, the cup 14 is liquid in the valve open state. When mounted on the container body 2, the top surface member 21 is formed by the cup inner surface 14a.
Is pressed downward, and as a result, the plug body 15 returns to the valve closed state as described above.

出することがない。As described above, in the stopper of the liquid container of the present invention, the top member is provided on the top of the stopper, and when the valve is closed, the top member contacts the upper edge of the outer stopper. It is located at the bottom dead point where it touches and closes the outlet of the liquid flow path in the stopper, and by pushing the push button, the top member is pushed up by the elastic one-sided projection provided at the bottom of the push button to open the valve. In some cases, the top member is located at the top dead center and the discharge port of the intracorporeal liquid flow path is opened. Therefore, since the discharge port is closed in the valve closed state,
Even if it is left with the cup removed, dust and dirt do not enter the inside of the stopper, which is hygienic and the water droplets that have accumulated in the liquid passage inside the stopper between the liquid injection valve and the discharge port leak out. There is nothing to do.

ダウンが可能となった。Further, an elastic piece is hung vertically on the lower surface of the push button so as to be integrated with the push button, an elastic piece locking claw is formed at the tip of the elastic piece, and an elastic piece projection is formed in the middle part.
When the push button is pressed, the elastic piece protrusion that descends pushes up the top surface member, and the slope portion of the elastic piece locking claw is locked by the lower surface of the projection formed on the inner surface of the inner plug. When the valve body is in the valve open state, the projection provided on the lower end of the top member presses the elastic piece projection when the top member is pressed in the discharge enabled state. By deforming the elastic piece locking claw that deforms in the inner diameter direction and is returned from the lower surface of the internal plug projection part to the valve closed state by the biasing force of the coil spring, the number of members that make up the valve opening / closing mechanism is reduced, and assembly is reduced. It is possible to reduce the cost easily.
