Abstract

L'invention concerne une membrane de fermeture (2) comportant une tête de fermeture (5) et une bordure de retenue (3), la tête de fermeture étant reliée à la bordure de retenue par l'intermédiaire d'une paroi de raccordement (4) adjacente à la bordure extérieure, le système entier présentant une configuration sensiblement cupuliforme. La tête de fermeture possède de préférence une épaisseur qui augmente du centre vers l'extérieur. Cette paroi de raccordement est fixée à la tête de fermeture par l'intermédiaire d'une partie jointive (51) qui est d'une moindre épaisseur que la région marginale de la tête de fermeture et qui, en position de repos de la membrane, est en saillie radiale vers l'intérieur par rapport à la paroi de raccordement.
