A pressurized container A for under-cup charging which comprises a container main body 1 equipped with a bead portion 6 at a periphery of an opening at its upper end, a mounting cup 18 having a curved flange 18d which engages with the bead portion 6, a flexible inner bag which is interposed between

A pressurized container A for under-cup charging which comprises a container main body 1 equipped with a bead portion 6 at a periphery of an opening at its upper end, a mounting cup 18 having a curved flange 18d which engages with the bead portion 6, a flexible inner bag which is interposed between the container main body 1 and the mounting cup 18. The inner bag 2 is equipped with a neck portion which abuts tightly against an outer peripheral surface of a rising wall of the mounting cup with predetermined fitting strength and a flange portion 11 which is disposed at the upper end of the neck portion and clamped between the curved flange and the bead portion. The flange portion 11 exhibits a sealing function when pressed to the inner surface of the curved flange 18d with a charging pressure at the time of under-cup charging and also when clamped between the curved flange 18d and the bead portion 6 after assembly.
