Abstract
A self-opening and re-sealable pouring element of plastics material for application to a pack for liquids, and in particular a composite card/plastics material pack, has a base part which has an attaching flange, having a cutting element and a screw cap, the cutting element being rotatably arranged in the interior of the base part and operatively connected to the screw cap such that when the screw cap is unscrewed for the first time, an opening for pouring is produced by the cutting element in the material of the pack, wherein, when produced in an injection mold, the cutting element is already entirely arranged in the interior of the base part and is spaced away from the base part by a plurality of connecting bridges.
