The self-opening closure consists of a pouring spout (10), which can be assembled leak-proof on a combipack or on a container spout to be sealed with foil material, appropriate twist cap (9) as well as a self-opening sleeve (1) arranged inside the pouring spout (10). This can be made to rotate by the twist cap (9). The self-opening sleeve (1) forms on its upper edge an indentation (4), which becomes smaller towards the bottom edge (6) and tapers off into the same. There are guiding means present on the outer side of the self-opening sleeve (1) and on the inner side of the pouring spout (10) so that the self-opening sleeve (1) is guided downwards by the rotation on the pouring spout (10). The indentation (4) lies partially inside the pouring spout (10) and partially below the same after the unscrewing of the cover cap and forms an air inlet channel, which results in a steady outpour during the pouring out of the liquid content of a combipack.
