Abstract

L'invention concerne un générateur d'aérosol (104) qui comprend un contenant externe (106) comprenant une extrémité inférieure fermée et un col ouvert longitudinalement opposé à l'extrémité inférieure fermée (108). Le générateur d'aérosol comprend en outre une valve (112) scellée au col ouvert d'une manière étanche aux fluides. Le générateur d'aérosol comprend en outre un contenant de produit (114) disposé à l'intérieur du contenant externe et contenant un produit à l'intérieur de celui-ci. Le contenant de produit est couplé de manière fluidique à la valve d'une manière étanche aux fluides. La valve (112) est configurée pour sélectivement projeter le produit à partir du contenant de produit. Le contenant externe (116) définit, à l'intérieur de celui-ci, un volume de contenant qui est à l'extérieur du contenant de produit (114) et entoure au moins partiellement le contenant de produit (114). Le volume de contenant contient un gaz sous pression à l'intérieur de celui-ci, de telle sorte que le gaz sous pression met sous pression le produit à l'intérieur du contenant de produit à une pression supérieure à une pression ambiante pour sélectivement projeter le produit à travers la valve (112). Le produit est un adhésif.
