Abstract
A container (100), such as a cooler, has a center section (108), a bottom section, and a cover or lid. The center section has a plurality of outer walls (202) and a plurality of partial columns (210). Each outer wall has an inner surface (206), an outer surface (202), a top surface, a thickness, and a plane (204, 208) defined by the outer surface. Each partial column has an inner surface (214), an outer surface (212), a top surface (218), and a thickness, and defines a corner angle (216), such as approximately 90 degrees. The partial columns alternate with the outer walls, and the outer surface of a partial column extends beyond the plane of an adjacent outer wall. The center section and the bottom section are a unitary structure formed of a flexible insulating material, such as an EVA foam.
