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

1. A process for producing a double dispensing device;by providing a pressure-transmittable barrier wall to separate an inside of a vessel into a first chamber and a second chamber, a dispensing valve, a passage to connect the dispensing valve with the first chamber, and a check valve means capable of flowing fluid from the first chamber to the second chamber in a pressure vessel; loading pressurized gas substantially insoluble to stock solution into the first chamber from the valve through the passage, and further bringing the pressurized gas to the second chamber through the check valve means; and loading stock solution into the first chamber through the passage from the valve.
