Pouring Element for a Composite Package with a Cutting Element for the First Opening of the Composite Package and a Package Provided with Such a Pouring Element

Abstract

Described and illustrated is a pouring element for a composite package. The pouring element includes a main body with a hollow cylindrical spout and a flange arranged at an axial end of the spout; a hollow cylindrical cutting element, guided in a movable manner in the spout, with at least one cutting tooth for opening the composite package; and a reclosable screw cap, which, when the composite package is initially opened, serves to drive the cutting element; wherein the main body, the spout, the cutting element, and the screw cap are arranged concentrically about a vertical axis and wherein the outer hollow cylinder wall of the cutting element has a screw thread, which serves as a movable guide in the spout. In order to design and further develop known pouring elements such that the forces necessary to assemble the cutting element and main body can be decreased and that the force for assembly can be reduced to prevent possible damage to parts due to high forces, the inner hollow cylinder wall of the spout has at least one internal thread having a lower thread section and an upper thread section, the upper thread section of the internal thread has a radially reduced average thread height compared to the lower thread section, and the lower thread section spans half a turn of helix rotation of the at least one internal thread on the axial end of the spout where the flange is arranged.
