METHOD FOR PRODUCING A DOUBLE AEROSOL DEVICE AND CONTAINER THEREFOR

摘要

A method for a double aerosol device having a piston (2) functioning as a check valve for allowing a gas to move from below to above the piston, while preventing it from moving from above to below, said method comprising the steps of loading a pressurized gas insoluble in a stock solution into a first chamber (N1) below said piston (2) through a valve (6) (process S2), allowing said pressurized gas to move into a second chamber (N2) above said piston and transferring said pressurized gas in said first chamber (N1) into said second chamber (N2) by similarly loading stock solution into said first chamber (N1) (process S3).
