Abstract
A blow-molded plastic bottle body for use in containing hot-filled beverages. The bottle body has a dome with various interactive functional zones. 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 column 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 dome, and not merely selected locations, reacts in a progressive manner to the forces generated by the hot-fill process on the bottle body. Preferably, the bottle body is slender and capable of readily being gripped by a single hand, and preferably the flex panels in the dome accommodate at least 90% of the total vacuum absorption required by the bottle.
