Une libération du scellage de la membrane doit se produire, l'application de force durant le remplissage par le bas étant favorable ou pouvant être supportée. À cette fin, le conteneur est muni d'une paroi de conteneur (40), d'une ouverture de conteneur (2), d'un couvercle (10), de la membrane (30) et d'une structure de support (20). Le couvercle (10) ferme l'ouverture de conteneur (2). Une section d'une collerette de membrane (31) de la membrane (30) est fixée à une section de la face interne (41) de la paroi de conteneur (40), de telle façon qu'une zone de fixation (33) est formée. La structure de support (2) présente une section de support (21) et une section porteuse (22). La section de support (21) est affectée à la membrane (30) et la section porteuse (22) est affectée au couvercle (10).
