Bottle-type plastic container with vacuum absorption panels for hot-fill applications

摘要

A bottle-type plastic container has a body and an opening at one end of the container that allows liquid content to be filled into the container and emptied therefrom. The body includes at least one body portion having a substantially regular polygonal cross-section defined by a plurality of generally flat walls. The generally flat walls of the body portion include flexible walls and less-flexible walls, which are arranged alternately to each other in a circumferential direction of the body portion. When the container is filled with liquid contents at a high temperature and subsequently cooled to room temperature, a resultant pressure drop within the container is absorbed by the walls, initially by a primary inward deflection of the flexible walls and subsequently by a secondary inward deflection of the less-flexible walls. As such, the plastic container is particularly suited for hot fill applications.
