ABSTRACT:
A closure for a container with a cap connecting to a neck of the container has at least one cutter edge placed around a central axis internal of the neck. The edge cuts through a closure film as axially displaced on a holding sleeve, which is held centrally by the cap with a flexible skirt. The holding sleeve contains a component for mixing with the contents of the container. A screw cap holds an initial non-puncturing position and, a stop position after additional screwing on, at which the film is punctured. The cap remains permanently on the neck of the container, and includes a pouring opening. In the stop position, the container contents flow toward the pouring opening. When the screw cap is back into its initial position, flow to the pouring opening is interrupted.
