摘要： A testing apparatus for testing the level of retained gas at elevated pressure in plastic containers for carbonated beverages includes a manifold assembly for engaging the mouth of a test set of the containers. The apparatus additionally includes a gas supply for supplying a desired quantity of a selected gas to each container, the gas preferably helium. The apparatus further includes pressure measuring units for measuring the pressure in each container, and a data collection system coupled to the pressure measuring units for periodically collecting pressure data along with ambient temperature data as a function of time. The collected data can be analyzed to determine shelf life of the containers. Using helium, the shelf life determination can be accomplished in about 1/7th the time of conventional shelf life tests.

摘要： A plastic container comprises a lower base forming portion that includes a plurality of circumferentially spaced downwardly convex segments (126) and a plurality of intervening, circumferentially spaced, totally convex, hollow foot forming portions (121) that extend radially from the central bottom portion (120) and downwardly from the downwardly convex segments to form a clearance (124) for the central bottom portion. The downwardly convex segments have smoothly curved cross sections, in radially extending planes through their central regions and coplanar with the container's longitudinal axis (120a). The clearance forming portion (123) of each foot forming portion includes a compound curved offset formed with opposing radii of curvature lying in a range of about 15% to over about 30% of foot contact diameter, the compound curved offset curving downwardly and outwardly about a center of curvature (131) below the bottom forming portion before curving about a center of curvature (130) above the bottom forming portion.
