It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim:

1. A rectangular sheet metal container the side walls of which are embossed inwardly to form a central panel, leaving outwardly raised marginal portions, and, extending from said marginal portions toward the middle of the pane1, spaced-apart projections which remain in the plane of the marginal portions and have between them depressed parts which are in the plane of the panel, thereby making discontinuous the edges of the panels and strengthening the side walls of the container against fracture along said edges.

2. A rectangular container of sheet metal comprising, a body having a plurality of side walls, ends secured to said body, the material of the side walls being bent at intervals adjacent the vertical corners of the container to provide a central side wall panel and pressed side wall edge portions separated from each other and closely spaced together and forming an indentured pattern, the outwardly pressed parts of the pattern merging into the corner portions, and the inwardly pressed parts merging into the central part of the wall.

3. A rectangular container comprising a body having a plurality of side walls and ends secured to said body, the marginal portion of said side walls adjacent and between its corner portions being pressed inwardly at spaced intervals to provide a pattern integral with and extending inwardly of the body wall and the outer portion of said pattern merging into the plane of the side walls to provide a predetermined zone of fiexure.

4. A rectangular container comprising a body having a plurality of side walls and ends double seamed to the side walls, said side walls being pressed into an inwardly projecting marginal cas'tellated and indentured pattern integral with and disposed adjacent the vertical and horizontal corners and the double seamed ends, the outer portion of said pattern being in the plane of the body wall, to allow for flexing movement of the body Wall and to prevent concentration of rupturing strains and sharp bending of the metal thereof.

5. A rectangular metal container the side walls of which are formed with a central panel, and series of inwardly projecting tongues spaced apart and surrounding the panel and constituting an integral part thereof, the bases of said tongues being merged with and in the plane of the metal of the corner portions of the container, to strengthen the corners and give flexibility to the walls, and guard against fracture.
