In the pallet container which is equipped with a plastic inner container and a lattice jacket of vertical and horizontal lattice rods (9, 10) of metal, stacking and transport safety is achieved by special design of intersections (15) where lattice rods (9, 10) are welded to one another. At intersections (15) lattice rods (9, 10) are indented to form double-walled, cavity-like depressions (16). Depressions (16) have center elevation (17). At each intersection (15) between longitudinal edges (18, 19) of center elevations (17) of depressions (16) of two lattice rods (9, 10) which lie at right angles on top of one another, this shaping of lattice rods (9, 10) results in formation of four contact points (20) which lie in one plane, each with a material accumulation which corresponds to four times the wall thickness of the lattice rods. Lattice rods (9, 10) are joined to one another by electrical resistance pressure welding or electrical spot welding at intersections (15) in the area of four contact points (20). Sections (25, 26) of cavity-like depression (16) of lattice rods (9, 10), the sections adjacent on each side to elevation (17) with contact and welding points (20), form bending points of limited elasticity with a bending resistance moment which is reduced relative to elevation (17) to relieve the welds at intersections (15) under static and/or dynamic loading of the lattice jacket. |
