Publication number: 20240010410Abstract: A container having an inverted active cage generally includes an enclosed base portion, a body portion extending upwardly from the base portion, and a top portion with a finish extending upwardly from the body portion. The body portion further includes a central longitudinal axis, a periphery, a plurality of rigidified and non-active surfaces, and a network of pillars or channels. Unlike the prior art, each of the plurality of non-active surfaces is outwardly displaced with respect to the longitudinal axis, while each of the network of pillars or channels is inwardly displaced with respect to the longitudinal axis. The plurality of rigidified or non-active surfaces, together with the network of rigidified channels or pillars, are spaced about the periphery of the container in order to accommodate vacuum-induced volumetric shrinkage of the container resulting from a hot-filling, capping and cooling thereof.Type: ApplicationFiled: July 5, 2023Publication date: January 11, 2024Applicant: CO2Pac LimitedInventors: David Murray MELROSE, Campbell John MELROSE-ALLEN

Patent number: 11377286Abstract: A hot-fill PET container or bottle (10) filling with a liquid at an elevated temperature has a side wall (9) extending to a lower portion including a pressure panel (11) and a base (21) in its unfolded or pre-fill position. The panel (11) is transversely oriented and has a decoupling or hinge structure or element (13), an initiator portion (1) and control portion (5) of a steeply angled inverting conical section between 30 and 45 degrees. The control portion enables the inversion of the panel (11) into the container (10) to compensate for vacuum or reduced pressure induced within the container as the liquid cools down. The base (2) can also have a plurality of reinforcing ribs (3).Type: GrantFiled: April 27, 2019Date of Patent: July 5, 2022Assignee: CO2 PAC LimitedInventor: David Murray Melrose

Patent number: 11155373Abstract: To modify the headspace in a container to remove vacuum pressure, a container has a seal or cap which may provide a temporary opening into the container which is sealable under compression to provide a controlled raising of the internal pressure as the heated contents of the container cools. A sealing chamber (84) may enable the introduction of a fluid into the headspace (23b) to force the fluid level (40) lower. Other methods and apparatus are described.Type: GrantFiled: November 7, 2016Date of Patent: October 26, 2021Inventor: David Murray Melrose
