Abstract
A container, suitable as a hot-fill container, includes a controlled deflection flex panel which may invert and flex under pressure, such as hot-fill conditions, to avoid deformation and permanent buckling of the container. The flex panel includes an initiator portion which has a lesser projection than the remainder of the flex panel and initiates deflection of the flex panel.
