Abstract
A hot fill container formed from a polymeric material is disclosed. The container comprises a base (4), a body (2), and a neck (1), wherein the body (2) comprises an odd number of spaced-apart panels (5) that are responsive to internal pressure changes in the container. Hot fill bottles of a given capacity having an uneven number of deformable panels, e.g., five of a given wall thickness, unexpectedly accommodate significantly higher volume reductions before collapsing and distorting in an uncontrolled manner than known hot fill bottles of the same capacity having an even number of panels, e.g., six of the same wall thickness.
