A foil container formed from a single sheet of metal about orthogonal longitudinal and transverse axes, comprises a bottom panel, a continuous wall panel, and a continuous rim. The continuous wall panel encompasses the bottom panel and extends upwardly and outwardly from the bottom panel. The continuous rim encompasses an upper edge of the continuous wall panel and projects laterally outwardly therefrom. The bottom panel is constructed and arranged bend strength and aesthetic appeal of the container. In one embodiment, the bottom panel forms a network of clusters including hexagonal ribs, hexagonal embossments, and bar ribs. In another embodiment, the bottom panel forms a plurality of closely spaced, concentric elliptical ribs that occupy a substantial portion of the bottom panel.

[ What is claimed is:] [1.] A foil container formed from a single sheet of metal about orthogonal longitudinal and transverse axes, comprising:a generally rectangular bottom panel having a peripbery;a continuous wall panel encompassing said bottom panel and extending upwardly and outwardly from said bottom panel, said continuous wall panel forming a pair of opposing side walls and a pair of opposing end walls, said end walls bridging said side walls, said side walls being at least as long as said end walls; anda continuous rim encompassing an upper edge of said continuous wall panel and projecting laterally outwardly therefrom;said bottom panel forming a plurality of closely spaced, concentric non-circular elliptical ribs, said elliptical ribs occupying a substantial portion of said bottom panel, said elliptical ribs having respective centers coinciding with a center of said bottom panel, an outermost one of said elliptical ribs being located in close proximity to said pair of opposing side walls, an innermost one of said elliptical ribs being located in close proximity to the center of said bottom panel, said bottom panel also forming a pair of outer rib structures generally occupying corners of said bottom panel and located outside said outermost one of said elliptical ribs, each of said outer ribs structures including a curved portion and a straight portion defining closed loops at respective ends of said bottom panel, said curved portion having approximately the same curvature as said elliptical ribs and being concave with respect to the center of said bottom panel, said straight portion conforming to a portion of said periphety of said generally rectangular bottom panel.
