Patent

CA 2607923

The invention relates to a stopper device (1), comprising an external cap (10) made from plastic and an internal fixed fixing insert (20) for fixing the device around the neck of the container (2). The sleeve (12) of the cap successively comprises, along the (X-X) axis thereof, a head (13), into which the insert may be introduced and permanently fixed and a skirt (14) extending axially from the insert. According to the invention, contamination on the neck of the container (2) with said device may be limited and the appearance thereof improved, whereby, particularly at the base of the neck, the skirt (14) essentially forms a frustum (142) converging towards the axis of the sleeve on extending from the head, before the installation of said device around the neck, said frustum forming, at the end (144) thereof opposite the head (13), an internal surface (144B) to come into contact against the container neck under the influence of an elastic deformation of the sleeve (12) as a result of the installation of the device around the neck.

Ce dispositif de bouchage (1) comporte un capuchon externe (10) en plastique et un insert interne (20) de fixation amovible du dispositif autour du col de récipient (2). Le manchon (12) du capuchon comprend, successivement suivant son axe (X-X), une tête (13), dans laquelle l'insert est adapté pour être introduit et solidarisé à demeure, et une jupe (14) s'étendant axialement au- delà de l'insert. Pour limiter l'encrassement et améliorer l'esthétique du col de récipient (2) équipé de ce dispositif, notamment ô la base du col, la jupe (14) forme pour l'essentiel, avant mise en place du dispositif autour du col, un tronc de cône (142) convergent vers l'axe du manchon en s'éloignant de la tête, lequel tronc de cône ménage, à son extrémité (144) opposée à la tête (13), une surface intérieure (144B) adaptée pour venir en appui contre le col de récipient sous l'action d'une déformation élastique du manchon (12) résultant de la mise en place du dispositif autour du col.
