CONTAINER WITH PAN FOR TRANSPORTATION AND STORAGE OF LIQUIDS Russian patent published in 1998 - IPC

FIELD: materials handling. SUBSTANCE: container with pan has replaceable inner plastic reservoir and latticed shell consisting of vertical and horizontal metal latticed bars. Safety of stacking and transportation is provided owing to special way of crossing to the bars and special welding of the latter. Bars in points of intersection forced in to form mould-shaped two-wall recesses provided with middle rise. Owing to deformation of latticed bars in each point of intersection, four places of contact with accumulation of material, corresponding to four-fold thickness of latticed bars, are formed between longitudinal edges of middle rise in recesses of two latticed bars lying square on each other. Latticed bars are connected in places of intersection in zone of four points of contact by resistance spot welding or pressure welding. Sections of recesses of bars adjoining the rise with places of contact and welding at two sides form limited-flexibility bending sections with decreased bending resistant moment relative to rise to unload welding joints in places of crossing at static and/or dynamic load on latticed envelope. EFFECT: enlarged operating capabilities. 4 cl, 7 dwg
