PURPOSE:To fill a gas through an aerosol valve, by providing a cylindrical member which has a gas hole and is fitted in the open part of an outer container. CONSTITUTION:A liquid is filled into an inner container 2. An aerosol valve is inserted into a member 3 and fitted on an outer container 1 by a cap 13. When a stem 6 is pushed down, a liquid passage 8 is closed by the protrusion 7 of the stem. After that, a gas is filled under pressure. The gas flows through a stem hole 10 and a gas passage 9 so that a gas hole 4 closed by the upper end of the inner container 2 is opened by the pressure and the gas is filled between the inner and the outer containers 2, 1. After the gas is filled, the gas hole 4 is tightly closed by the gas pressure. |
