摘要

A resealable pouring element for cardboard / plastic composite packs (P), in particular beverage packs, is shown and described, with a base element (2, 2 ') having a circumferential fastening flange (1, 1', 1 ") and an external thread (10, 10 '). , 2 "), with opening means arranged at least in the unopened state of the pouring element inside the base element (2, 2 ', 2") and a screw cap (3, 3', 3 ") with an internal thread, the opening means being designed so that When the composite pack (P) is first opened when the screw cap (3, 3 ', 3 ") is unscrewed, a pouring opening is created within the pouring element by breaking open the composite material of the pack (P) or a barrier layer in the base element (2, 2', 2") will. In order to ensure a connection of the screw cap to the pouring element in such a reclosable pouring element even when it is unscrewed, it is provided that underneath the screw cap (3, 3 ', 3 ") an anchor ring (4, 4', 4") is non-rotatably connected to it. is arranged, which is radially freely rotatable around the base element (2, 2 ', 2 ") and is connected to the base element (2, 2', 2") with tensile strength in the axial direction and that for secure connection of the screw cap (3, 3 ') , 3 ") to the base element (2, 2 ', 2") even in the unscrewed state of the anchor ring (4, 4', 4 ") via a hinge element (5, 5 ') whose pivot axis is tangential to the outer circumference of the screw cap (3 , 3 ', 3 "), is hinged to the screw cap (3, 3', 3").
