Abstract
The inventive closure unit has a hinge (4), which pivotally interconnects the pouring part (1) and the closure part (2). The hinge (4) comprises at least one bearing part and a pivot part pivotally mounted on the bearing pan. The closure unit is produced according to a multimaterial injection molding process, in such a way that the beating parts are made from one material and the pivot parts from another. As a result of the good matching of such materials molded on one another the pairs of beating surfaces are also tight, so that the hinge (4) can take over part of the sealing function between the pouring pan (1) and the closure pan (2).
