Abstract: In an easily hand-held metal container construction for containing a product under pressure wherein the container construction has an outwardly convex bottom wall and an adjoining side wall defined as a single-piece structure with the side wall terminating at a top portion adapted to have a top closure fixed thereon, the improvement wherein the downwardly convex bottom wall has a plurality of integral feet supporting the container construction thereon, each of the feet being defined by a downwardly convex dimple having a base portion provided with an outer periphery, a rounded outer portion, and a wall thickness which is substantially the same thickness as the remainder of the bottom wall, and each of the dimples having a central axis and the outer periphery of its base portion disposed radially inwardly from the side wall by a distance at least equal to one half the minimum dimension across the outer periphery measured through the central axis.

Abstract: Compacted-particle sheets are wrought from essentially scrap aluminum. A relatively thick composite laminate of such sheets is then produced by preheating a plurality of compacted-particle sheets and bonding them together by hot rolling in a single pass through a hot rolling mill to achieve a thickness reduction of about 50 percent. A second pass through a rolling mill results in a further 20 percent reduction and improved bonding. Improved laminate qualities are also obtained by further laminating with other aluminum alloys and other metals.
