<P>PROBLEM TO BE SOLVED: To provide a double structure aerosol container which solves problems concerning safety, filling volume of a content, cooling damage caused by a temperature decrease of a jetted material, shrinking jet volume caused by a pressure decrease in a jet agent, or the like. <P>SOLUTION: The double structure aerosol container contains the jet agent and the content stored separately, and comprises an outer cylindrical can 1 and an inner bag 2 which is inside the outer cylindrical can 1 and is filled with the content. The jet agent and an absorbent are filled into a gap between the outer cylindrical can 1 and the inner bag 2. According to the absorbent, a BET specific surface area is 500-3,500 m<SP>2</SP>/g, a total pore volume is 0.3-2 cm<SP>3</SP>/g, an average pore diameter is 7-20 Å, and the total volume of the pores having a diameter of 20 Å or smaller accounts for 70% or more of the total pore volume. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
