Abstract: A flat and low pourer closure for composite packs or container openings, which are preferably closed with a thick foil, includes a bottom part which, with the bottom side of its base plate, is intended to be welded, or otherwise fixed, on a composite pack or thick foil. The base plate has a drain opening and at least one projection which juts upwardly and surrounds the base plate. There is a cover which swivels on a hinge towards the bottom part and can be swiveled downwardly and tightly on the bottom part as a collar; which collar runs around the bottom side of the cover and matches with the one or more projections on the bottom part. In the internal drain opening on the base plate, a break-off plate, with its outer edge following the inner edge of the drain opening, is formed through at least two material bridges as breaking points.
