Publication number: 20140147608Abstract: A container, according to various embodiments of the invention, includes a co-extruded, blow molded wall that comprises: (1) a first, inner surface layer, (2) a second, interior layer; and (3) a third layer. In one embodiment, the inner surface layer comprises an extrusion blow-molding-capable grade of PET; the second, interior layer comprises adhesive; and the third layer comprises a polyolefin and the regrind material from one or more containers similar to the blow molded container. In various embodiments, the third layer is an outer surface layer of the blow molded wall. Alternatively, the container may further comprise a fourth (e.g., exterior surface) layer that comprises a polyolefin. In other embodiments, the inner surface layer comprises an extrusion blow-molding-capable grade of PET; the second, interior layer comprises a barrier material, such as polyamide resin, EVOH, or a compatible oxygen scavenger; and the third layer comprises an extrusion blow-molding-capable grade of PET.Type: ApplicationFiled: February 3, 2014Publication date: May 29, 2014Applicant: CONSOLIDATED CONTAINER COMPANY LPInventors: Mihaela Penescu, Wayne Barron

Patent number: 6964197Abstract: 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.Type: GrantFiled: October 16, 2001Date of Patent: November 15, 2005Assignee: Ball CorporationInventors: Craig P. Davis, Stephen C. Ramey, Mary L. Hughes-Olson, Edward R. Roberts, Mihaela Penescu
