PURPOSE: To form a soln. having proper concn. even in a liquid stream under pressure by providing a multiple pressure-resistant harmetically closed container to the flow route of a sprinkling apparatus and adjusting the amt. of the solvent flowing in the chemical agent received in an inner container. CONSTITUTION: A pressure resistant hermetically closed container provided with joints 1, 2 is provided so as to be capable of being connected to the hose, piping and sprinkling port of a sprinkling apparatus by using a simple tool such as a spanner. The interior of an outer container 3 of this container is partitioned in a multiple state and an inner container 4 devised so as to gradually dissolve or dilute a chemical agent is provided therein. A lid 5 inserting or injecting the chemical agent is provided to the container for dissolving the chemical agent therein. A liquid inlet 7 provided with a valve 6 capable of being adjusted so as to allow a proper amt. of a solvent to flow in and an outflow port 8 allowing a soln. of the dissolved or diluted chemical agent to flow out are provided to the inner container. A container 9 for suppressing the ejection of water from the gap between the valve 6 and the outer container 3 may be provided. |
