PURPOSE:To control a gas discharge quantity from a discharge port by adjusting the contracting quantity of a flow rate controlling valve by relatively turning a container main body and a lid body. CONSTITUTION:In a main body 2 of a container 1, an aromatizing agent 12, which is a liquid or solid, etc., is stored. Under a condition where a cylindrical shaped thin film 6 gives a normal cylindrical shape without any deformation, as a flow rate controlling valve 5, it is under the totally opened condition, and a volatile gas from the aromatizing agent 12, i.e., the fragrance is gradually discharged to the outside of the container, e.g., the interior of an automobile, etc., through a discharge port 4. ln this case, by turning a lid body 3, the cylindrical shaped thin film 6 can be deformed, and the flow rate controlling valve 5 can be totally closed or the inner diameter can be continuously changed without steps. Thus, the fragrance discharge quantity from the aromatizing agent 12 can be freely controlled. |
