Le capuchon de fermeture présente une partie de montage (10) et une partie de séparation et de distribution (20; 21, 21a,25) ainsi qu'une partie d'actionnement (30; 35), servant à commencer à dégager une voie d'écoulement (D) à travers la partie de distribution du contenant (B). La partie de distribution (20) et la partie d'actionnement (30) sont placées de manière adjacente. La partie de distribution (20) présente une partie tranchante (21, 21a) tubulaire et un élément poussoir (35) est associé à la partie d'actionnement. La partie tranchante (21, 21a) ainsi que l'élément poussoir (35) peuvent se déplacer ensemble dans le sens axial. Un organe d'accouplement (31,31a) accouple l'élément poussoir (35) et la partie tranchante (21, 21a) de sorte qu'un mouvement axial (z1) de l'élément poussoir en forme de bouton est converti en un mouvement axial (z2) de la partie tranchante tubulaire. Ce capuchon assure une fermeture hygiénique du contenant.
