PURPOSE: An apparatus for double vacuum packing of a perfume is provided to simply inflate a rubber tube and a balloon using gas generated by chemical reaction between fluids caused by bursting a packaging. CONSTITUTION: A method for double vacuum packing is as follows. A solid or fluid(110) is vacuum-packed. Another solid or fluid surrounds a first vacuum package(100) to be packed. When the solid and fluid packed in the first vacuum-packing step and the material packed in the second vacuum packing step contacted each other, a new gaseous compound or fluid compound are manufactured by the chemical reaction. When the solid or fluid packed in the second vacuum packing step is put in contact with the solid and fluid packed in the first vacuum-packing step, the solid or fluid packed in the second vacuum packing step includes a catalyst for generating and diffusing gas.
