Abstract

L'invention concerne un système (1) de fourniture d'aérosol comprenant un élément (14) de transport de matériau aérosolisable servant à recevoir un matériau aérosolisable à vaporiser. Le système (1) de fourniture d'aérosol est mobile entre une première configuration, dans laquelle au moins une partie de l'élément (14) de transport de matériau aérosolisable n'est pas comprimée ou est partiellement comprimée et une seconde configuration, dans laquelle la partie de l'élément (14) de transport de matériau aérosolisable est comprimée à une proportion supérieure à celle dans la première configuration pour restreindre la formation du matériau aérosolisable vaporisé en provenance de l'élément de transport de matériau aérosolisable dans la seconde configuration. Le système (1) de fourniture d'aérosol peut comprendre un tube de sortie de fluide (26) qui est conçu pour se déplacer entre la première configuration et la seconde configuration pour amener la partie (31) de l'élément (14) de transport de matériau aérosolisable à être comprimée dans la seconde configuration.
