Device For Closing A Container Comprising Secure Closure Means

A device for closing a container, of the type including a cap assembly including a cap intended to be placed on the container or to be removed from that container by a relative movement between the cap and the container including an axial component, the cap carrying at least two essentially diametrically opposite security projections, each provided with an axial locking abutment that can be moved radially between:

• a cooperation position, favored by elastic biasing, in which the locking abutment is intended to cooperate with a complementary locking abutment carried by the container to retain the cap on the container,
• a separation position, in which the locking abutment is intended to be separated from the complementary locking abutment carried by the container to allow the release of the cap relative to the container,
• further comprising a security ring mounted around the cap so as to allow radial elastic deformation thereof by ovalization when the security ring is compressed radially in at least one compression direction,
• the security projections being arranged on an internal surface of the security ring and aligned in a direction essentially perpendicular to the compression direction,
• the radial position of each axial locking abutment carried by the security ring changing, by ovalization of this security ring, from its cooperation position to its separation position,
• and comprising a mechanism for snap-fitting the security ring onto the cap, which can be activated by an essentially axial relative movement between the security ring and the cap, the mechanism for snap-fitting the security ring onto the cap being active regardless of whether or not the security ring is ovalized.
