PROBLEM TO BE SOLVED: To improve sealing properties of a container main body of a double aerosol product, thereby making an aerosol propellant hardly leak therefrom. SOLUTION: A sealing structure 35 for a double aerosol product comprises: a bead part 24 formed in an opening at the upper end of a container main body 11; a flange 28 provided at the upper end of an inner bag 12 to be contained in the container main body and disposed above the upper surface of the bead part 24; a cross-sectionally inverted U-shaped curved flange 34 provided around a mounting cap 14 to be crimped to the opening of the container main body so as to cover the flange 28 and the bead part 24; and an annular packing 36 interposed between the bead part 24 of the container main body and the flange 28 of the inner bag. The packing 36 is bonded to the underface of the flange 28 of the inner bag 12 in advance to be held thereon. |
