A pallet container for storing and transporting in particular flammable or easily ignitable liquid filling materials has a composite base plate, a thin-walled rigid internal container made from a thermoplastic plastics material, a tubular lattice frame that as a supporting jacket tightly encloses the plastics-material internal container, and a base pallet on which the plastics-material container bears and to which the tubular lattice frame is fixedly connected. The plastics-material internal container is on all sides enclosed by a fire-protection insulation mat. The composite base pallet is equipped with a heat-resistant support element for maintaining the resistance thereof in the case of heat acting thereon over a comparatively long period at each plastics-material corner foot.
