Abstract

Dans un récipient traditionnel, si le contenu est susceptible de se détériorer lorsqu'il est exposé à l'air, un bouchon de taille plus petite est fixé au récipient par réduction du diamètre d'une partie du col du côté de l'ouverture de façon à réduire la zone de contact entre l'air et le contenu. Toutefois, de cette manière, un intervalle se forme entre l'ouverture du récipient et une partie de la plaque supérieure du bouchon, ce qui empêche la formation d'une force d'engagement suffisante entre eux. Dans le cas de ce récipient traditionnel, celui-ci n'est pas complètement hermétique et une force considérable est nécessaire pour l'ouvrir et le fermer avec le bouchon. Dans le cas du récipient de l'invention, une partie du col d'engagement (30) du bouchon, dont le diamètre interne et le diamètre externe sont plus larges qu'une partie du col (13) du côté de l'ouverture, est formée au niveau de la partie du col (14) du côté de l'épaulement du récipient de la partie col (10). Ceci permet d'adapter sur le récipient un bouchon de plus grande taille.
