Abstract

The present invention relates to an assembly for closing a tube. The assembly includes a tube head including a neck and a closure liner sealing the neck. The assembly also includes a cap that includes a punch adapted to cut the closure liner. The neck and the cap are configured to allow the cap to be fixedly held on the neck in a first position—the standby position—in which the punch is held at a distance from the closure liner, and in a second position—the position of use—in which the punch perforates the closure liner.
