Abstract
Provided is a hot-fill container adapted to provide vertical vacuum compensation in response to negative pressure inside the container. The container comprises one or more horizontal ribs that are configured to diminish in height in response to vacuum conditions inside the container. Each rib comprises an upper wall connected to a lower wall. The upper and lower walls are inclined from a horizontal reference line and adapted to hinge with respect to each other to provide vertical vacuum compensation.
