| titleOfInvention | Sustained release device |
| abstract | (57) [Problem] To provide a sustained-release device for surely releasing a saturated aqueous solution of an additive at a stable concentration when water flow is stopped. SOLUTION: A main pipe 4, a cartridge 2 filled with an additive therein, and an aqueous solution of the additive present in the cartridge are gradually and gradually released into a small amount of water flowing through the main pipe. In the controlled release device 1 provided with the controlled release pipes 7 and 9, the controlled release of the aqueous solution of the additive is performed only when the water is passed through the main pipe, and when the flow of the main pipe is stopped, the controlled release pipe is shut off. As a result, the sustained release of the aqueous solution in the cartridge is reliably stopped, and the aqueous solution of the additive does not diffuse into the main pipe. |
