Definitions

• the invention relates to a secure opening cap for a container.
• documents US 5,316,162 and US 5,520,305 describe caps with a secure opening comprising a ring adapted to be secured to the neck of a container and a removable cap vis-à-vis the ring.
• the ring has a circumferential groove and the cap comprises a lug arranged in the groove of the ring.
• the groove of the ring opens into a groove extending axially towards the cap, the width of the groove being greater than or equal to that of the lug.
• the cap is movable in pivoting about a longitudinal axis of the cap by sliding the lug in the ring. As long as the lug is not entirely opposite the groove, the cap is thus retained by the ring in the closed position.
• the cap To open the cap, the cap must be rotated relative to the ring so as to bring the lug opposite the groove, which allows the cap to be released by a simple pull in the axial direction.
• the correct position is indicated by an alignment of two arrows present respectively on the ring and the cap.
• the cap can be closed by positioning the lug opposite the groove, pushing the cap in and then rotating it so as to engage the lug in the circumferential groove and thus hold the cap on the ring.
• a drawback of these caps is that in the open position the cap is separated from the container and is therefore liable to be lost or to fall, with a risk of soiling or damage. To avoid this type of inconvenience, it is known practice to connect the cap to the container by a hinge.
• An aim of the invention is therefore to design a secure opening stopper which overcomes the aforementioned drawbacks.

• the cap comprising a lug configured to slide in the groove and into the groove, the groove being configured as such so that the second part of the stopper can be handled in relation to the first part between:
• the lug and the rib having respective shapes adapted to allow closure of the stopper by snapping the lug in the groove in any position other than the start position unlocking.

From this end-of-unlocking position, a user can release the outlet of the container by exerting a force to pivot the cap around the axis of the hinge, thus bringing the cap into its open position.

• the face of the rib is shaped so as to prevent such sliding of the face of the lug; for example, in this zone, the face of the rib forms a sufficiently high step to prevent the passage of the lug towards the groove.
• the cap can be closed in any position other than that of the start of unlocking. This ensures that, after closing, the lug is retained in the groove, away from the intersection with the groove. Therefore, even if the user does not rotate the assembly of the retaining ring and cap relative to the container after folding the cap back onto the container, the cap is not in the unlock position and function. safe opening remains fulfilled.
