Device For Closing A Container Including Improved Secure Closure Means

A device for closing a container, of the type including a cap assembly including an internal cap member intended to be placed on the container or to be removed from that container by a relative movement between the internal cap member and the container including an axial component, the internal cap member carrying a security element including a locking abutment mobile 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 internal cap member 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 internal cap member relative to the container,
• characterized in that it further includes
• an external cap member mounted to be axially mobile on the internal cap member, the external cap member carrying the security element, and
• a mechanism for transforming the axial movement of the external cap member on the internal cap member into radial movement of the security element making it possible for the radial position of the locking abutment to evolve from its cooperation position to its separation position by axial movement of the external cap member relative to the internal cap member in a direction identical to a direction of the axial component of the movement of the internal cap member toward the container during the placing of that internal cap member on the container.
