Abstract:
A hot fill container of the type that is used package fruit juices and other beverages includes a vacuum panel configuration that provides optimal volumetric efficiency, material usage and container strength and is particularly suited for use with smaller containers. The vacuum panel configuration includes a plurality of cageless vacuum panels that are separated by longitudinally extending outwardly projecting creases that are defined in a sidewall of the container. This arrangement maximizes the effective surface area of the vacuum panels relative to the external surface area of the container. Each of the longitudinally extending outwardly projecting creases has a curved outer surface that is convex when viewed in longitudinal cross-section. The cageless vacuum panels are constructed and arranged to be convexly curved when a pressure within the container is equal to an external pressure, but become concavely curved when a predetermined partial vacuum condition exists within said container.
