Abstract

La présente invention concerne un procédé relatif à un double dispositif pour aérosol. Un piston (2) joue le rôle de clapet antiretour pour permettre à un gaz de passer d'en dessous à au-dessus du piston tout en empêchant l'inverse. Le procédé comprend le chargement d'un gaz sous pression, insoluble dans une solution stable, dans un premier compartiment (N1) situé en dessous du piston (2), en passant par une soupape 6 (processus S2), ce qui permet à ce gaz sous pression d'aller dans un deuxième compartiment (N2), situé au-dessus du piston, et de le transférer du premier compartiment (N1) au deuxième compartiment (N2) en plaçant de manière similaire la solution stable dans le premier compartiment N1 (processus S3).
