Abstract: A flexible hot fill container includes a body having a label portion and a flex portion. The flex portion includes flex panels and support structure fields. Both the support structure fields and flex panels deform inwardly upon vacuum conditions. Recess sidewalls in the flex panels provide support.

Abstract: A container has features to enable it to withstand pressure filling, including a smooth transition between its sidewalls and vacuum panel, no vertical stiffeners on the edges of the vacuum panels, and a gripping portion having wall either with small radial components or oriented at oblique angles. A pair of windows are included in the field portion of the vacuum panel outside of the gripping portion.

Abstract: The instant invention concerns a composition comprising a base polymer, at least one compound of the formula E-(L-E)x wherein: E is and L is a linking group; and at least one transition metal in a positive oxidation state.

Abstract: The present invention concerns a method for forming an article by combining a polyester polymer and an oxygen scavenging composition comprising a polyamide in the presence of zinc and a cobalt in a melt processing zone to form a melt; and forming an article such as a sheet or preform from the melt. Also provided are molten formulated polyester polymer compositions containing a blend of a polyethylene terephthalate polymer and a polyamide polymer along with zinc and cobalt. Articles made from the composition are resistant to the transmission of oxygen, possess short induction periods, and have high capacity for sustaining lengthy periods of low oxygen transmission through the wall of the article.

Abstract: The present invention provides a wall for a package, which wall comprises, or includes a layer comprising, a composition comprising a polymer and capable of scavenging oxygen through the metal-catalysed oxidation of an oxidizable organic component thereof. The oxidizable organic component is preferably itself a polymer, and may be the only polymer in the composition. Preferred compositions include a blend of 96% polyethylene terephthalate and 4% poly (m-xylyleneadipamide) containing 200 ppm cobalt as catalyst, with good permeance-versus-time performance (3) when formed into a bottle.

Abstract: A blow-molded plastic container is provided suitable for hot-filling under pressurize-fill conditions, and under gravity-fill conditions. The container includes opposing handgrips within panels, which lack hinges and thus do not function as conventional vacuum panels as the inward deformation is spread beyond the panels. The hand grip includes a distal, relatively stiffened portion formed by a sidewall that forms a thumb piece and a proximal, relatively un-stiffened portion the smooth merges into a cylindrical sidewall of the container.

Abstract: In a process for making a multi-chambered container that is lightweight, relatively inexpensive to produce, and that requires less external reinforcement against flexure than conventional multi-chambered containers do, a parison is heated and inflated to form the container. Further, first and second pinched-in areas are fashioned in the sidewall of the container. The first pinched-in area includes first and second wall portions that extend inwardly toward an interior of the main body of the container, and a first end wall portion connecting the first and second wall portions. The second pinched-in area includes third and fourth wall portions that extend inwardly toward an interior of the main body, and a second end wall portion connecting the third and fourth wall portions.
