  • Patent number: 11078002
    Abstract: A pallet container for storage and for transport of hazardous liquid or flowable materials includes a thin-walled rigid inner container made from thermoplastic, with a tubular lattice frame surrounding the inner container and having horizontal and vertical tubular rods welded together, and a rectangular base pallet supporting the inner container and connected to the tubular lattice frame. Two parallel rod-shaped crossbars extend across the top, laterally next to the upper filler neck of the cube-shaped inner container, to which the top of the inner container is fastened by means of two holders. The holders are formed in the course of the upper pinch-off seam from the plastic material of the inner container during blow molding. The top of the plastic inner container is fitted with two solid stable crossbar supporting pins which are open at the side and each engage over the two crossbars.
