Abstract
The present invention relates to an assembly for the closure of a tube. The assembly includes a cap that includes a punch adapted to cut a seal. The seal is adapted to seal a neck of a tube head. The cap is configured to be fixed to the neck in a first position, known as the standby position, and a second position, known as the use position. The assembly also includes a ring movably fixed to the cap. The assembly is configured to allow the passage from an extended position, with the aim of the punch being protected by the ring in the standby position of the cap, to a retracted position, with the aim of the seal being pierced by the punch in the use position of the cap, a passage of the assembly from the extended position to the retracted position being effected by a sliding of the cap through the ring.
