Abstract

Pour fournir un système d'aérosol de recharge qui peut facilement effectuer une opération de dégazage avec une configuration simple même lorsqu'un récipient parent remplit un agent de pulvérisation à l'extérieur d'un sac interne d'un récipient à double structure, et qui est apte à retirer et à remplir rapidement et suffisamment un contenu-liquide du récipient parent vers un récipient enfant avec une perte moindre de l'agent de pulvérisation lors du remplissage.　Un système d'aérosol (100) est apte à remplir un contenu-liquide (F) à l'intérieur d'un récipient parent (110) dans un récipient enfant (120). Le récipient parent (110) comporte une première tige parent (112) correspondant à une partie de réception de contenu-liquide (115) et une seconde tige parent (113) correspondant à une partie de réception d'agent de pulvérisation (116). La partie de réception de contenu-liquide (115) est pressée par la pression d'un agent de pulvérisation côté récipient parent (MG). La pression interne à l'intérieur du récipient parent (110) est supérieure à la pression interne à l'intérieur du récipient enfant (120). Le contenu-liquide (F) pulvérisé à partir de la première tige parent (112) du récipient parent (110) peut être introduit dans le récipient enfant (120) par l'intermédiaire d'une tige d'enfant (122) du récipient enfant (120).
