CORNER STRUCTURE OF SIDE PLATE OF SHEET METAL MADE CONTAINER AND SHEET METAL MADE CONTAINER EQUIPPED WITH SIDE PLATE WITH CORNER PART

摘要

<P>PROBLEM TO BE SOLVED: To solve the problem that a conventional metal-made container can have a breakage or a crack occurring at a bottom plate of a triangle corner part and around a crossing point of a perpendicular longer side plate and a perpendicular shorter side plate, and has a disadvantage of leakage of a liquid in the container. Ž<P>SOLUTION: A container includes a structure having a bottom plate made of a metal flat plate, two pieces of perpendicular side plates formed in one piece with the flat plate and a triangle corner part formed by being folded back and bent in a triangle shape continuously to two pieces of the perpendicular side plates and includes a hairpin shaped rib with a space which extends near to the crossing point of the flat plate and two perpendicular side plates along a slant face of the corner part and extends almost parallel with the flat plate and continuously at the lower part of one perpendicular side plate.
