摘要： A plastic container that is adapted for adjustment to internal volumetric changes such as those that typically occur during the hot fill process includes a container body defining an internal space. The container body has a sidewall that is shaped to define at least one flexible panel. The flexible panel has a central longitudinal axis, an upper portion, a lower portion and a central portion. The central portion of the flexible panel has a width that is greater than a respective width of at least one of the upper and lower portions. The flexible panel is substantially flat as viewed in a longitudinal cross-section taken along the central longitudinal axis. Additionally, the central portion has a transverse radius of curvature that is greater than a transverse radius of curvature of at least one of the upper portion and said lower portion. Because the central portion represents the maximum width of the flexible panel, the efficiency of vacuum uptake is maximized with respect to conventional vacuum panels that are substantially flat in longitudinal cross-section.
