Represented and described is a resealable pouring element for cardboard/plastic composite packages, in particular beverage packages, with a base element with a circumferential fastening flange as well as an external thread, with opening means arranged at least in the unopened state of the pouring element in the interior of the base element and with a screw cap with internal thread. The opening means are designed such that when the composite package is initially opened by unscrewing the screw cap by breaking the composite material of the package or a barrier layer located in the base element, a pour opening is created inside the pouring element. In order to ensure a fastening of the screw cap to the pouring element in such a resealable pouring element, even in the unscrewed stale, it is provided that an anchor ring is arranged below the screw cap, is connected thereto in a rotationally-fixed manner and is connected to the base element so as to be radially freely rotatable around the base element and in a tension-resistant manner in the axial direction and in that, to securely fasten the screw cap to the base element, even in the unscrewed state, the anchor ring is connected to the screw cap a hinged manner via a hinge element, whose pivot axis is aligned tangentially to the outer circumference of the screw cap.
