PURPOSE:To permit contents to be sprayed easily and accurately in a smooth state without using CFC by a method wherein a resilient bag member is provided in a container body and its contents and gas-containing microcapsules are placed and mixed therein. CONSTITUTION:To fill contents 13, a spray orifice 4b of a sprayer 1 is connected to an arbitrary filling machine and the contents, together with microcapsules 14, are forcibly fed under a high pressure into a bag member 7 against the resilient force thereof. Upon removal of the filling machine, a valve disk 10 is closed and the contents 13 are retained in a container body 2. When a pressing part 8 of a spray nozzle 4 is depressed, the valve disk 10 is pressed by a valve stem 9 to be opened. Since the bag member 7 normally attempts to return to its original shape, a spray of the contents 13 is shot out from the spray orifice 4b of the spray nozzle 4. At this time, the microcapsules 14 are also shot out together with the contents 13 and momentarily balanced unevenly in pressure to be burst. In this way the carbon dioxide enclosed in the microcapsules are liberated to expand liquid chemical or the like into a smooth state. |
