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.

A re-closable pouring element for liquid foods 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,
- wherein the opening element has a solidly constructed outer thread and is arranged inside the base and wherein the opening element is formed in such a way that when the cap is operated for the first time, it cuts an opening in the package material located under the pouring element,
- wherein the outer thread of the opening element is reduced or interrupted in the lower section at least in one region and the inner thread of the base is likewise reduced or interrupted at least in a corresponding region, so that during initial assembly the opening element can be moved into the base axially from above without screwing in, pressing or over-compressing the inner thread of the base and the outer thread of the element.
A method for assembling a pouring element having a base encircled by a flange and including 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, wherein the opening element has a solidly constructed outer thread and is arranged inside the base and wherein the opening element is formed in such a way that when the cap is operated for the first time, it cuts an opening in the package material located under the pouring element, wherein the outer thread of the opening element is reduced or interrupted in the lower section at least in one region and the inner thread of the base is likewise reduced or interrupted at least in corresponding region, so that during initial assembly the opening element can be moved into the base axially from above without screwing in, pressing or over-compressing the inner thread of the base and the outer thread of the opening element, the method comprising the steps of:
- a) aligning radially and moving the opening element into the base axially from above, and
- b) fitting the screw cap at the same time or afterwards.
