Re-closable pouring element for liquid foods packaged in cardboard/plastic composite packages, consisting of a base (1) encircled by a flange (4) and having both a solidly constructed inner thread (5) and an outer thread (6), an opening element (2) having at least one cutting edge (10) or the like and a screw cap (3) formed as a threaded lid, wherein the opening element (2) has a solidly constructed outer thread (8) and is arranged inside the base (1) and wherein the opening element (2) is formed in such a way that when the cap (3) is operated for the first time, it cuts an opening in the package material located under the pouring element The user is translated into an opening operation, so that reliable opening of a sufficiently large opening for pouring is ensured. For that the outer thread (8) of the opening element (2) is reduced or interrupted in the lower section at least in one region (8F) and the inner thread (5) of the base (1) is likewise reduced or interrupted at least in a corresponding region, so that during initial assembly the opening element (2) can be moved into the base (1) axially from above without screwing in, pressing or over-compressing the threads (5, 8). |
