[Action]

 The water flowing down from the upper part of the container 1 flows into the tank through the water holes 30 which communicate with the inside of the tank 29 through the water holes 13 at the bottom of the support 2, but a part of the water is injected into the weight member 6. At this time, the water injected into the weight member 6 is discharged from the small through hole 28 of the bottom wall 25, but the water is accumulated in the weight member 6 due to the difference between the injection amount and the injection amount, and Since the vertical movement member 5 is pulled down against the resilience of the spring 24, the blockage of the communication hole 21 by the valve plate 23 is released, and the chemical solution in the container body 3 moves from the communication hole 21 to the outside of the valve plate 23. Since the passage valve plate 23 flows down into the water flow hole 30 until it abuts the upper surface of the locking projection 12 to close the flow path, a substantially fixed amount of the chemical liquid flows into the tank.

Further, when the inflow of water into the tank is completed, the water in the weight member 6 is also discharged through the small through holes 28, and as a result, the vertical movement member 5 is lifted by the force of the spring 24 and the valve plate The communication hole 21 is blocked by 23, but at this time as well, a substantially predetermined amount of the chemical liquid flows down into the tank, and as a result, the vertical movement of the up-and-down moving member 5 constantly causes a substantially fixed amount of the chemical liquid into the tank. Run down.
