へ入り、その負圧状態を解消する。In the embodiment shown in FIG. 1, the liquid is sucked into the cylinder 7 by moving the pressing head 15 up and down several times in advance. When the pressing head 15 is pressed down from this state,
Since both the suction valve plate 5 and the discharge valve 32 are in a closed state,
As the cylinder 7 descends, the pressure in the cylinder increases, and the pressure in the cylinder opens the discharge valve 32 to discharge from the nozzle 22. When the pressing head is released from the lowered state, the head is pushed up by the upward bias of the coil spring 35, and the discharge valve 32 is released.
Is closed, the pressure in the cylinder becomes negative, the suction valve plate 5 opens, and the liquid in the container is sucked into the cylinder through the suction pipe 13. The pressure in the container is reduced by the decrease in the liquid in the container, but the pressure is reduced by lowering the press-down head 15 so that the lower end of the second elastic skirt-shaped portion 31 is bored in the inner surface of the outside air suction tube 8. When positioned inside the outside air intake vertical groove 11, the main body member 1
The outside air enters the inside of the container through the space between the guide cylinder 9 and the outer peripheral wall 17 of the pressing head, the vertical groove 11, and the outside air suction hole 10, and the negative pressure state is eliminated.
