Abstract: A re-closable pouring element for liquid foods packaged in cardboard/plastic composite packages, comprising a base encircled by a flange and having both an inner thread and an outer thread, an opening element having at least one cutting edge as well as perforations and a screw cap formed as a threaded lid. The opening element has an outer thread and is arranged inside the base. The opening element is formed so that when the screw cap is operated for the first time it cuts an opening in the package material located under the pouring element. At least one window opening is provided as an aperture, each window opening is arranged so that it points to one side after opening for the first time and after re-closing and repeated opening for emptying residues of the composite package points to the opposite side.
