PROBLEM TO BE SOLVED: To enable an amount of stored content left in an inner container to be confirmed conveniently in a double-walled aerosol container comprised of an inner container storing the content and an outer container storing the inner container. SOLUTION: A double-walled aerosol container 2 is comprised of an outer container 4 having an opening segment 4a, a valve segment 6 fixed to the outer container so as to close the opening segment 4a, and an inner bag 8 fixed to the valve segment. Acid hair dye is stored in the inner bag 8 as stored content. The outer container 4 is formed by polyethylene terephthalate and the entire outer container is transparent. In turn, the inner bag 8 is formed into a pleat shape. As acid hair dye is discharged out of the inner bag 8, the pleated segments are gathered together, shrunk and deformed. A user can confirm a shrunk deformation of the inner bag 8 through the outer container 4 and further confirm conveniently the amount of acid hair dye left in it in reference to a degree of deformation. |
