Patent

CA 2620375

A valved closure for a liquid container is disclosed. The valved closure comprises a closure body having a base and a spout. A generally tubular insert is provided with an upper portion attached to the lower portion of the base. The insert body is sized to fit within a dispensing port of the liquid container and defines an insert passageway in fluid communication with the spout. The insert has at least one flexible flange extending outwardly therefrom for resiliently engaging the inner wall of the container and seal the closure to the container. A valve is retained between the insert and the closure body to operatively open and close the fluid passage through the closure from the container.

La présente invention vise une fermeture à soupape pour conteneur de liquide qui comporte un corps de fermeture ayant une base et un bec verseur. Un insert généralement tubulaire est doté d'une partie supérieure fixée à la partie inférieure de la base. Le corps d'insert est dimensionné de façon à tenir à l'intérieur d'un orifice de débit du conteneur à liquide et définit un passage d'insert en communication fluide avec le bec verseur. L'insert a au moins une bride flexible qui se prolonge vers l'extérieur à partir de celui-ci pour venir en prise résiliente avec la paroi interne du conteneur et assurer une fermeture hermétique du conteneur. Une soupape est retenue entre l'insert et le corps de fermeture pour ouvrir et fermer fonctionnellement le passage de fluide par la fermeture à partir du conteneur.
