The invention relates to a closure for a container containing a contents, particularly a bottle or the like made of plastic, glass or the like, with a cap, particularly made of plastic, for sealingly connecting to a neck of the container having an edge, with at least one cutter edge, which is placed around a central axis of the cap in the area of the internal width of the neck and which serves to cut through a closure film when the at least one cutter edge is axially displaced through the closure film. The cutter edge is placed on a holding sleeve, which is held in an essentially central manner by the cap by means of a flexible skirt and is to be displaced relative to the cap toward the closure film. The holding sleeve contains a component provided for mixing the contents of the container. A screw cap, which can be screwed onto and back from the cap, is provided with an initial screwed position, in which the closure film has not yet been ruptured, and with a stop screwed position after additional screwing on, in which the closure film is punctured by the at least one cutter edge and the component is exposed. The cap, after the sealing connection, remains permanently on the neck of the container, and the screw cap comprising, like a sport cap, a pouring and/or drinking opening. In the stop screwed position, the container contents are permitted to flow toward the screw cap and its pouring and/or drinking opening. When screwing the screw cap back into its initial position, flow to the screw cap and its pouring opening is interrupted once again.
