Abstract:
A container with improved strength, said container having an internal containment space, which comprises:a container wall disposed around a vertical axis;a bottom attached to said container wall, having a supporting surface, a sidewall connecting said container wall to said supporting surface, a center panel, the major portion of which is disposed radially inwardly of said supporting surface, and a panel positioning portion connecting said supporting surface to said center panel, said panel positioning portion having an upper end and a lower end, said center panel having an upwardly extending outer portion;wherein said support surface forms a support surface radius interconnecting said support surface to said lower end of said panel positioning portion;said panel positioning portion comprising:a first panel positioning part, contiguous with said supporting surface, wherein at least the uppermost portion of said first panel positioning part slopes inwardly and upwardly relative to supporting surface;a second panel positioning part, interconnected, at its upper edge with said outer portion of said center panel, to define a wall radius between said upper edge of said second panel positioning part and said outer portion of said center panel, and positioned above said first panel positioning part;said second panel positioning part, interconnected, at its lower edge with said first panel positioning part to define an inter-part radius between said first panel positioning part and said second panel positioning part and wherein said inter-part radius is separate, distinct from and spaced from each of said wall radius and said support surface radius, said inter-part radius being located at a vertical level between said wall radius and said support surface radius; andwherein said outer wall, said sidewall, said first panel positioning part, and said second panel positioning part, substantially define at least a portion of said internal containment space.
