A molded polymeric container generally symmetric about a vertical axis includes at least two rows of panels disposed circumferentially around the body, the panels having central portions that are sufficiently flexible to be dimensionally responsive to changes in pressure within the container. At least one row of the panels has a margin having a horizontal width exceeding the vertical height, thus being laterally elongate with a height/width aspect ratio of less than one. The pressure responsive central portion of each laterally elongate panel is a smooth outwardly projecting dome from a peripheral root of a generally radially projecting wall defining the margins of circumferential rings and posts separating the panels. Panels in another row can have an ovate step connecting the perimeter of the panel to the central portion of the panel. Outward protrusions can be provided within the central portion to provide support for a surrounding label.
