    • 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.
    • 由共挤出型吹塑工艺生产的容器,其由基本上刚性的外部容器和容易变形的内部袋组成,其中当内部袋在吹气的底部被挤压时,内部袋被底部焊缝封闭 模具,并且所述底部焊缝被夹紧在外部容器的同样封闭的底部焊缝中,至少一个压力补偿开口形成在底部焊缝的两侧,并且所有压力补偿开口形成在外部的点 容器从圆周方向偏离从底部焊缝延伸的平面和容器的纵向中心轴线与外部容器的圆周壁和内部袋的相交线,使得内部袋仅收缩 当分配容器内容物时的两侧,其特征在于内袋的壁厚在区域o中更大 f相对于插入的圆周部分的交点。
