Abstract

L'objectif de la présente invention est de fournir un outil pour verser et un récipient d'emballage permettant d'augmenter les propriétés de barrière à l'oxygène tout en améliorant l'esthétique externe, le remplissage de contenus et la fonctionnalité de versement. La présente invention comprend un bec verseur 1 qui est disposé sur un récipient d'emballage et un capuchon qui ferme le bec verseur 1. Le bec verseur 1 est pourvu d'un corps 11 de bec verseur qui est disposé sur le récipient d'emballage et d'un corps cylindrique 12 qui est disposé au-dessus du corps 11 de bec verseur. Dans une section d'ouverture K couverte par une section de paroi périphérique 22 du capuchon 2, le corps cylindrique 12 du bec verseur 1 est pourvu d'une section d'ouverture à paroi mince supérieure 12a qui est formée pour être à paroi mince et d'une section d'ouverture à paroi épaisse inférieure 12b qui est formée pour être à paroi épaisse. Lorsqu'il est inséré dans un passage d'écoulement 13 à travers le corps cylindrique 12 du bec verseur 1A, un bouchon 23 pour le capuchon 2 est positionné dans une région de la section d'ouverture K du bec verseur 1 recouverte par la section de paroi périphérique 22 du capuchon 2, et ferme le passage d'écoulement à travers la section d'ouverture à paroi mince 12a du corps cylindrique 12 en établissant un contact avec la section d'ouverture à paroi épaisse 12b du corps cylindrique 12.
