Abstract
A disposable foil container formed from a single sheet of metal comprises a bottom panel, a continuous wall panel, and a continuous rim. The bottom panel includes an upwardly-projecting rib configuration wherein a peripheral rib, having first and second opposing side curved sections and first and second opposing end curved sections, encompasses a pair of traversing ribs, first and second returning ribs, and a central portion of the bottom panel. Each curved traversing rib extends towards the central portion, has a first end intersecting with said first side curved section, and has a second end intersecting with said second side curved section at a first set of intersections. Each traversing rib is bisected into substantially equal parts by a major axis. The first returning rib has first and second ends intersecting said first side curved section and the second returning rib has first and second ends intersecting said second curved section at a second set of intersections. Each returning rib is bisected into equal parts by a minor axis. All of the ribs have rounded tops. The first and second set of intersections form smooth curvilinear corners and have a minimized flat top surface a…
