Abstract: A pourer spout for a composite package of the carton brick type, arranged to be located level with the opening zone of the latter. The pourer spout comprises a base (2) fixed onto the container around the opening zone, and an articulated cover (4), able to reclose the container after opening. A perforating piece (6) is mounted pivotally on the base (2), facing the opening zone, in order to be moved between an initial position in which it is situated entirely outside the container to a final position in which it is situated substantially inside the container. A striker (8) is mounted pivotally on the base (2) in order to push the perforating piece (6) towards the inside of the container while perforating the wall of the latter and to more or less take the initial position of the perforating piece (6), the striker (8) in this last position acting as pourer.
