Publication number: 20240109682Abstract: A plastic container comprises an upper portion including a finish defining an opening into the container, a lower portion including a base defining a standing surface, a sidewall extending between the upper portion and the lower portion, the sidewall defining a longitudinal axis, and at least one substantially transversely-oriented pressure panel located in the lower portion. The pressure panel is movable between an outwardly-inclined position and an inwardly-inclined position to compensate for a change of pressure inside the container. The standing surface defines a standing plane, and the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position.Type: ApplicationFiled: December 12, 2023Publication date: April 4, 2024Applicant: CO2PAC LimitedInventors: David MELROSE, Paul KELLEY, John DENNER, Gregory TRUDE
