PURPOSE: To facilitate insertion/mounting work by forming a definite interval between outer and inner cylindrical containers by forming specific relations between the angles of inclination of the respective shoulder parts of the outer and inner cylindrical containers and between the bead height in the axial direction of the outer cylindrical container and the neck height of the inner cylindrical container. CONSTITUTION: A corrosion-resistant aerosol container is constituted by inserting an inner cylindrical container 2 made of a synthetic resin in an outer cylindrical container 1 made of metal. In this case, the relation ofα>βis formed between the angleαof inclination of the shoulder part 1a of the outer cylindrical container 1 and the angleβof inclination of the shoulder part 2a of the inner cylindrical container 2. The relation of C<D is formed between the bead height C in the axial direction of the outer cylindrical container 1 and the neck height D of the inner cylindrical container 2. If the dimensions of the outer and inner cylindrical containers 1, 2 are determined, a sufficient interval is generated between them and, therefore, the insertion/mounting work of the shoulder parts 2a, 2c of the inner cylindrical container 2 becomes easy and the damage of the shoulder part 2a and the neck part 2c can be prevented.
