发明名称 Multi-layer plastic container having a carbon-treated internal surface and method for making the same
摘要 A blow molded multi-layer container is provided having an upper wall portion, including an opening; an intermediate sidewall portion positioned beneath the upper wall portion; and a base portion positioned beneath the intermediate sidewall portion, the base portion being adapted to dependently or independently support the container. The container includes (i) a molded inner layer formed from a plastic material, the inner layer having a vertical length and a carbon-treated inner surface; and (ii) a molded outer layer formed from recycled plastic that is substantially coextensive with the inner layer. The recycled outer layer comprises at least 40% by weight of the overall weight of the container, but can comprise more than 90% by weight, depending upon the needs of the application. In a preferred embodiment, the thickness of the inner and/or outer layers is controllably adjusted along their respective vertical lengths. If functionally desirable, the inner layer and/or outer layer may also include additional barrier materials and/or oxygen scavenging/reacting materials.
