Abstract
A hot-fillable, slender, blow-molded plastic bottle for use in containing hot-filled beverages. The bottle has a sidewall with various interactive zones of function. For example, some of the zones are primarily responsible for accommodating vacuum absorption, while other zones are primarily intended to rigidify the container such as by providing post strength to improve container top loading capability. Although each zone may have a primary function, each zone also aids adjacent zones in providing their functions. Thus, the entire sidewall, and not merely selected locations, reacts to the forces generated by the hot-fill process on the container.
