Abstract:
A lightweight container includes an enclosed base (12), an upper portion that extends upwardly to a finish; and a body (18) located between the base and the upper portion. The sidewall includes vacuum compensation elements (54a, 54b)that have an open end and an opposing closed end, and that form a V-shape. Each element has nested fields.
Abstract:
A plastic bottle includes any type of body and hoop supports that encircle the dome. The hoop supports may include continuous wave-like ribs; discontinuous ribs that are overlapping; plural, discrete segments that are inclined and overlapping; plural block-like segments formed of mutually perpendicular rectangles; indicia; horizontal segments in rows that overlap; and series of segments that are mutually interfering and overlaid. The hoop supports provide greater top load performance than conventional deep waist configurations.
Abstract:
The disclosure relates to oxygen scavenging molecules, compositions, methods of making the compositions, articles prepared from the compositions, and methods of making the articles. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
Abstract:
Containers comprise a base polymer and a color-correcting material The color of a polymer-based container is corrected by adding a effective amount of a color correcting matenal to a container compnsing a base polymer Other methods of correcting the color of a polymer-based container include mixing a base polymer with an effective amount of a color-correcting material to form a mixture, forming the mixture into a preform, and forming the preform into a container An effective amount of a color-correcting matenal can be injected at the trailing edge of a preform, and the preform can be formed into a container.
Abstract:
The invention relates to compounds of the structure of formula I and II: where X is selected from the group consisting of O, S and NH; Y, A and B are independently selected from the group consisting of N and CH; D, E and F are independently selected from the group consisting of CH, N, O and S; the symbol - represents a single or a double bond; and R 1 , R 2 and R 3 are independently selected from the group consisting of H, electron withdrawing groups and electron releasing groups. In other embodiments, the compounds are used as oxygen scavengers and in barrier compositions and articles.
Abstract:
A container has meta-stable panels to compensate for internal vacuum from hot filling. The panels include a groove that yields during deformation such that the stiffness of the panel varies from its pre-yield stage to its post-yield stage.
Abstract:
A container base that is capable of withstanding an internal pressure and further capable of causing an even deflection, such as that created by introducing liquefied gas during a hot filling process. The base includes a heel with a standing ring disposed at a lower portion thereon. A generally concave push up portion extends radially inward from the standing ring portion. At least two reinforcing rings are disposed on the push up portion, wherein the reinforcing rings diminish uneven deflection to prevent the container from tipping while resting on a flat surface.
Abstract:
ABSTRACT A container has plural vacuum panels located circumferentially around the body, an upper label area located above the panels, and a lower label area located below the panels. Each one of the upper label area and the lower label area have only one rib that is circumferential but for only one discontinuity. The discontinuities are vertically located approximately between the outer boundaries of one of the panels. The upper and lower discontinuities may be vertically aligned with one another or offset from one another.
Abstract:
The invention concerns compositions capable of scavenging oxygen which contain poly(ethylene terephthalate) base polymer and a nylon polymer. The compositions are formulated to provide improved clarity over current commercial products.
