A reinforced retortable plastic container includes a bottom portion and a main body portion having a plastic sidewall that is connected to the bottom portion. The main body portion has a reinforced sidewall area that includes a plurality of first sidewall portions and a plurality of second sidewall portions that are respectively interposed between the first sidewall portions. Each of the second sidewall portions is shaped to define a plurality of circumferentially spaced structures that are selected from the group consisting of indentations and projections. Each of the circumferentially spaced structures is interposed between adjacent vertical columns, and adjacent second sidewall portions are rotationally staggered with respect to each other so that the vertical columns on one second sidewall portion are not aligned with the vertical columns of an adjacent second sidewall portion. |
