Abstract
A re-closable pouring element for liquid food packaged in cardboard/plastic composite packages, comprising a base encircled by a flange and having both a solidly constructed inner thread and an outer thread, an opening element having at least one cutting edge and a screw cap formed as a threaded lid. The opening element has a solidly constructed outer thread and is arranged inside the base. The opening element is formed in such a way that when the screw cap is operated for the first time, it cuts an opening in the package material located under the pouring element.
