Claims9
A stopper made of synthetic material comprising:
- a band having an internal surface oriented towards an interior of the stopper;
- a cap for sealing a container and being articulated to the band by a hinge allowing the cap to be hinged to the band in a plane of an opening of the container or in a plane above the opening;
- an annular bead formed on the internal surface of the band to allow a snap-fastening of the stopper on a neck of the container and to prevent an upward movement of the band on the neck relative to the container while opening and closing the cap;
- and
- a non-annular protuberance formed on only one portion of the internal surface of the band above the annular bead, to bear on the portion which is fixed in relation to the container, and to prevent a downward movement of the band on the neck relative to the container while opening and closing the cap.
