Abstract

L'invention porte sur un ensemble récipient et capuchon comprenant un récipient et un capuchon. Le capuchon recouvre le récipient, et a un couvercle interne, un piston, un curseur et un couvercle externe. Le piston est disposé dans le couvercle interne, et est axialement mobile à l'intérieur de celui-ci. Le curseur est monté sur le piston et est mobile radialement pour déplacer le piston. Le couvercle externe reçoit le couvercle interne, le piston et le curseur. Le couvercle externe est mis en rotation dans une première direction pour fermer le récipient, et est mis en rotation de façon continue dans la première direction pour déplacer le curseur radialement et en va-et-vient de façon à déplacer le piston axialement et en va-et-vient. Le piston est déplacé pour évacuer l'air du récipient pour produire un vide ou un vide approximatif dans le récipient. Par conséquent, le contenu dans le récipient est protégé de l'humidité sans matériau déshydratant.
