Abstract
A double chamber aerosol container capable of filling contents in the container has a container cap that constitutes a liquid container with an inner sack to be temporarily fitted to a bead portion of an outer container while the inner sack is placed within the outer container. When the inner sack is placed with the outer container, the lower end of the inner sack is not in contact with the bottom of the interior of the outer container. The propellant is filled in the outer container upon forming a filling gap between the container cap and the bead portion, and then the container cap is surely clinched to the bead portion of the outer container.
