Zusammenfassung:The invention illustrates and describes a composite pack, in particular a parallelepipedal cardboard/plastic composite pack for pourable products, having an elliptical laminated hole which is provided in the composite pack gable, with an elliptical main axis and an elliptical minor axis, and a pouring element, comprising a basic body, a cutting element movably guided in the basic body and having the shape of a hollow cylinder with a cylinder outer diameter and a resealable screw cap, wherein the screw cap serves for opening the composite pack for the first time by activation of the cutting element, which thus forms a pouring opening in the region of the laminated hole and wherein first guidance means configured on the cutting element interact with second guidance means configured on the basic body. In order to create the largest possible outflow diameter, while maintaining an already existing variant of a laminated hole, or in order to optimise the system of laminated hole and cutting element below its normal limits, it is provided that the cylinder external diameter is at least as big as the length of the elliptical minor axis. This leads to the side wall of the hollow cylinder-shaped cutting element extending the laminated hole at least in sections.
