Container and process for making the same

A method of producing a multi-layer container, the method comprising

• extruding a core parison, an inner parison, and an outer parison,
• aligning the inner parison, the core parison, and the outer parison to cause the core parison to be located between the inner parison and the outer parison to cause the core parison to surround the inner parison and to be surrounded by the outer parison to form a multi-layer tube having an inner layer, an outer layer, and a core layer located between the inner layer and the outer layer,
• placing the multi-layer tube in a mold cavity formed in a mold,
• expanding the multi-layer tube to cause the outer layer to engage an inner surface of the mold and cause the multi-layer tube to deform to create a multi-layer vessel having an interior region, and
• trimming excess material from the multi-layer vessel to form a multi-layer container including an inner layer facing the interior region, an outer layer forming an exterior surface of the multi-layer container, and a core layer located between the inner layer and the outer layer,
• wherein the core layer of the multi-layer container has a density in a range of about 0.2 g/cm3 to about 0.6 g/cm3.

A multi-layer container comprising

• an inner layer arranged to face an interior region formed in the multi-layer container,
• an outer layer spaced-apart from the inner layer to form an outer surface of the multi-layer container, and
• a core layer comprising an insulative cellular non-aromatic polymeric material that extends between and interconnects the inner layer and the outer layer,
• wherein the multi-layer container has a density between about 0.4 g/cm3 to about 0.8 g/cm3.
