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