Abstract
Official abstract text for this publication.
A method for manufacturing a bottomed cuboid battery container includes: forming a first member by folding one piece of a first flat sheet, the first member being constructed of a quadrilateral bottom surface and first paired side surfaces, the first paired side surfaces continuing from the bottom surface and being oppose each other; and forming the bottomed cuboid battery container by welding each of a second flat sheet and a third flat sheet to the first member such that the second flat sheet and the third flat sheet oppose each other and constitute second paired side surfaces. The second flat sheet and the first member are welded from one direction. The third flat sheet and the first member are welded from one direction.

The invention claimed is: 1. A method for manufacturing a bottomed cuboid battery container comprising: forming a first member by folding one piece of a first flat sheet, the first member being constructed of a quadrilateral bottom surface and first paired side surfaces, the first paired side surfaces continuing from the quadrilateral bottom surface and being opposed to each other; and forming the bottomed cuboid battery container by welding each of a second flat sheet and a third flat sheet to the first member such that the second flat sheet and the third flat sheet oppose each other and constitute second paired side surfaces, the second flat sheet and the first member being welded from a side where one surface of the second flat sheet faces outside of the bottomed cuboid battery container, the third flat sheet and the first member being welded from a side where one surface of the third flat sheet faces outside of the bottomed cuboid battery container; wherein the second flat sheet and the third flat sheet are welded from outside of the bottomed cuboid battery container, wherein the first member includes a set of notches, wherein the second flat sheet and the third flat sheet are fitted to respective notches of the set of notches, and wherein depths of each of the notches are substantially equal to thicknesses of each of the second flat sheet and the third flat sheet. 2. The method for manufacturing a bottomed cuboid battery container according to claim 1 , wherein the second flat sheet and the third flat sheet are thicker than at least portions of the first member that constitute the first paired side surfaces. 3. The method for manufacturing a bottomed cuboid battery container according to claim 1 , further comprising forming recesses, to which the second flat sheet and the third flat sheet can be fitted, in the first paired side surfaces and the quadrilateral bottom surface of the first member. 4. The method for manufacturing a bottomed cuboid battery container according to claim 3 , wherein the forming recesses includes notching the portion of the first flat sheet to form the set of notches, the portion corresponding to ends of the quadrilateral bottom surface in a perpendicular direction to a direction in which the first paired side surfaces oppose each other. 5. The method for manufacturing a bottomed cuboid battery container according to claim 1 , wherein the first flat sheet is made of A1050 aluminum, and the second flat sheet and the third flat sheet are made of an A3003 aluminum alloy or an A5052 aluminum alloy. 6. A method for manufacturing a bottomed cuboid battery container comprising: forming a first member by folding one piece of a first flat sheet, the first member being constructed of a quadrilateral bottom surface and first paired side surfaces, the first paired side surfaces continuing from the quadrilateral bottom surface and being opposed to each other; and forming the bottomed cuboid battery container by welding each of a second flat sheet and a third flat sheet to the first member such that the second flat sheet and the third flat sheet oppose each other and constitute second paired side surfaces, the second flat sheet and the first member being welded from a side where one surface of the second flat sheet faces outside of the bottomed cuboid battery container, the third flat sheet and the first member being welded from a side where one surface of the third flat sheet faces outside of the bottomed cuboid battery container; wherein the second flat sheet and the third flat sheet are thicker than at least portions of the first member that constitute the first paired side surfaces, wherein the first member includes a set of notches, wherein the second flat sheet and the third flat sheet are fitted to respective notches of the set of notches, and wherein depths of each of the notches are substantially equal to thicknesses of each of the second flat sheet and the third flat sheet.
