Abstract

Un embout médical de l'invention (13) se fixe à un corps principal d'un contenant à nutriment et permet la communication entre l'intérieur et l'extérieur du corps principal. Ledit embout médical (13) comprend un corps principal (22) possédant un orifice traversant (21d), une paroi latérale (18) fixée au corps principal et une partie de raccordement (21) permettant de maintenir l'état de raccordement avec un raccord; une feuille mince (16) fixée au corps principal, placée de manière que l'embout médical soit fixé au corps principal, sur la ligne d'extension partant de l'orifice traversant à l'intérieur de ce dernier, et empêchant la matière liquide à l'intérieur du corps principal de s'écouler hors du contenant à nutriment; un pont (19a) relié au corps principal et pouvant être rompu ou déformé; et un élément de communication (19) dont une partie est insérée dans l'orifice traversant (21d) et raccordée au corps principal par le pont. L'élément de communication comprend une pièce qui peut percer la feuille mince lorsque l'élément de communication est poussé vers le côté du corps principal et rompt ou déforme le pont, et une voie d'écoulement qui, lorsque la feuille mince a été percée, permet à la matière liquide à l'intérieur du corps principal du contenant de s'écouler hors de ce dernier.
