[Action]

 In the state of FIG. 1, there is no water in the water receiver 31, and in this state, the piston member 20, the base member 25, and the water receiver 31 are in the raised position with respect to the container body 1 and the cylinder 6.

As shown in FIG. 2, when the water is discharged from the spout pipe 43 above the water receiving tray 41 in conjunction with the drainage of the tank, the water enters the water receiving tray 31 and its weight increases so as to resist the bias of the spring 13. Then, the base member 25 and the piston member 20 descend with respect to the cylinder 6. Then, the inside of the cylinder is pressurized to open the discharge valve 23, and the chemical liquid in the cylinder passes through the discharge pipe 22, the chemical liquid discharge hole 30, and the gap between the top wall 27 of the pedestal member and the bottom wall 32 of the water receiver 31. Into the water pan 41, and further into the tank 40 through the pipe 42 at the center of the water pan. On the other hand, the water that has entered the water receiver gradually passes through the drain hole 37 formed in the bottom wall 32 thereof, and also between the top wall 27 and the bottom wall 32 into the water receiving tray 41 and further into the tank. When the water enters, and therefore the amount of water decreases, the water receiver and the like rise due to the bias of the spring 13, and at this time, the suction valve 9 opens and the liquid chemical in the container is sucked up into the cylinder.

【Example】

 Reference numeral 1 denotes a container body that stands up a mouth / neck portion 4 from an upper end of a body portion 2 via a shoulder portion 3. Water collecting grooves 5 may be provided radially on the upper surface of the bottom wall 4.

The outer peripheral portion of the outward flange 7 attached to the upper end of the cylinder 6 is engaged with the upper end surface of the mouth / neck portion, and the cylinder 6 is suspended in the container body 1. The cylinder has a suction valve 9 on the inner surface of the lower end of a sliding cylinder portion 8 for a piston, and communicates with a suction valve hole to hang a suction pipe 10 to the bottom of the container body. A water absorption groove 11 is formed at the lower end of the suction pipe. Plural ridges 12 are provided on the inner periphery of the lower end of the sliding cylinder portion 8 and the upper end surfaces of these ridges 12 are used as mounting portions for the springs 13.

The cylinder 6 holds an outward flange 7 between a top wall 16 of a cap-shaped member 15 screwed into the mouth / neck portion 4 of the container body and an upper end surface of the mouth / neck portion 4. A discharge pipe insertion hole 17 is formed in the center of the top wall.

A tubular piston 21 of a piston member 20 is fitted in the sliding tubular portion 8 described above, and a discharge pipe 22 rising from the tubular piston is passed through an insertion hole 17 of the cap-shaped member, Stands above the mouth and neck 4. A discharge valve 23 is provided in the lower end of the discharge pipe. The piston member is biased upward by the spring 13 described above.

A pedestal member 25 is a first peripheral wall 28 in which a fitting tube portion 26 watertightly fitted to the outer surface of the discharge pipe is loosely fitted from the central portion of the top wall 27 to the outer surface of the container body portion. From the outer periphery of the top wall 27, respectively. The lower end of the first peripheral wall may be folded upward and outward to form a water storage groove 29. With the water storage groove, it is possible to determine whether the drug solution in the container is normally mixed in the water in the tank. That is, the use of the colored chemical liquid causes the water in the water storage groove to be lightly colored due to the mixing of the chemical liquid. Therefore, if the stored water is colorless, the mixing of the chemical liquid is stopped.

A drug solution discharge hole 30 having a diameter smaller than that of the fitting cylinder portion 26 is formed in the top wall portion above the discharge pipe 23.

Reference numeral 31 denotes a water receiver, which raises the second peripheral wall 33 from the peripheral edge of the bottom wall 32 placed on the top wall 27, and the locking rod 34 from the bottom wall 32 to the chemical liquid discharge hole 30.
