Abstract

Cette cartouche peut être solidaire/détachée d'une section de corps d'un inhalateur d'arôme de type sans combustion comprenant une antenne qui émet des micro-ondes pour chauffer une source d'aérosol. La cartouche comprend un support pouvant contenir la source d'aérosol et ayant une section de réception d'antenne pouvant recevoir l'antenne de manière à pouvoir être insérée/retirée lorsque la cartouche est solidaire/détachée de la section de corps. Le support comprend les éléments suivants qui constituent une partie de celui-ci : une première section, et une seconde section ayant une force capillaire supérieure à celle de la première section. La première section et la seconde section sont disposées en parallèle par rapport à la direction d'insertion/retrait de l'antenne.
