Abstract: A method for authenticating a closure assembly of a container including a closure and an overpack covering at least the closure. The overpack, including a first radio frequency identification tag having a first unique identifier, the method includes reading the first unique identifier, the closure including a second radio frequency identification tag including a second unique identifier and a storage unit including at least data relating to an overpack/closure pair including the unique identifiers of a closure and an overpack associated with the closure, reading the first unique identifier and comparing the identifiers of the overpack and of the closure thus read to verify that the pair being authenticated does coincide with the pair defined in the data assembly, emitting a communication signal corresponding to the result of the verification, the closure assembly including means for destroying at least one of the identification tags when the container is opened.

Abstract: A stopper head (1) to be secured to a stopper body (2) to form a stopper for a container, includes a base (3) on which a lug (4) is positioned such that it protrudes, the lug (4) being designed to cooperate with the body during the assembly of the body and the lug (4), the lug (4) including at least one recess (5) opening laterally, at both of its ends, such that the lug (4) is crossed through to anchor the body with the head (1).
