Abstract
A blow molded container having barrier properties and including an upper wall portion having an opening, an intermediate sidewall portion positioned beneath the upper wall portion, and a base portion positioned beneath the intermediate sidewall portion to support the container. The container includes a molded outer layer having an inner surface and an outer surface formed from at least 40% of recycled plastic, and a carbon coating formed on the inner surface of the outer layer and adhered thereto and substantially coextensive with the outer layer, wherein said carbon coating has a thickness of less than about 10 microns. A blow molded multi-layer container is also 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.
Claims (11)
1. A blow molded multi-layer container including an upper wall portion having an opening, an intermediate sidewall portion positioned beneath the upper wall portion, and a base portion positioned beneath the intermediate sidewall portion and adapted to support the container, said container further comprising: a molded outer layer having an inner surface and an outer surface and including recycled plastic; a carbon coating formed adjacent the inner surface of the outer layer and adhered thereto and substantially coextensive with the outer layer, wherein said carbon coating has a thickness less than about 10 microns, wherein said container can be recycled.
2. A container according to claim 1, wherein said outer layer has a thickness from 6 to 23 mils, and wherein the carbon coating has a thickness of 0.05 to 10 microns.
3. A container according to claim 1 or 2, wherein the thickness of the outer layer varies so that the intermediate sidewall portion is thinner than the upper wall portion and the base portion.
4. A container according to any one of claims 1 to 3, including a barrier material added to the outer layer.
5. A container according to any one of claims 1 to 4, wherein the carbon is coated on the inner surface of the blow molded container from at least one gaseous hydrocarbon.
6. A container according to any one of claims 1 to 5, wherein the carbon coating is amorphous.
7. A container according to any one of claims 1 to 6, wherein the carbon coating has one of a generally uniform thickness, and a thickness that varies along the vertical length of the container.
8. A container according to any one of claims 1 to 7, including at least one of the upper portion of the container including a support flange, and the base portion includes a plurality of feet.
9. A container according to any one of claims 1 to 8, wherein the outer layer is colored.
10. A container according to any one of claims 1 to 9, wherein the outer layer includes at least 75% of recycled plastic.
11. A container according to any one of claims 1 to 10, wherein the outer layer includes at least 40% of recycled plastic.
