Abstract

The container produced in a coextrusion-type blow molding process, which consists of a substantially rigid outer container and an easily deformable inner bag, with the inner bag being closed by a bottom weld seam when excess material is squeezed off at the bottom of a blow mold, and said bottom weld seam being clamped in a likewise closed bottom weld seam of the outer container, at least one pressure compensating opening being formed on both sides of the bottom weld seam, and all pressure compensating openings being formed at points of the outer container that are offset in the circumferential direction from the intersection lines of a plane extending through the bottom weld seam and through the longitudinal center axis of the container with the circumferential wall of the outer container and of the inner bag so that the inner bag contracts only from two sides when the container contents is dispensed, is characterized in that the wall thickness of the inner bag is greater in the area of the intersection lines than in the interposed circumferential portions.
