Abstract
A hot-fill container may have a shoulder portion, body portion, bottom portion, and numerous strengthening grooves and a thin-walled, flexible, bag-like, collapsible portion in the body portion. The collapsible portion may be located between the strengthening ribs. The container structure may also employ one or more vacuum panels in the body portion that may lie between the collapsible portion and the bottom portion. The vacuum panels and the collapsible body portion may move toward a central vertical axis when the container is subjected to an internal vacuum pressure. Strengthening grooves may border the collapsible body portion, which may be circular in pre-vacuum cross-section but polygonal in post-vacuum cross-section. Part of the collapsible portion may be concave inward toward a central vertical axis of the container while part of the collapsible portion may move away from the central vertical axis. Vertical columns may support the collapsible portion.
