A wire-frame or supporting framework for a bottle has an interior portion of high barrier, thin, non-toxic plastic, for example, blow-molded polyethylene naphalate, and an outer portion of rigid or semi-rigid plastic cage-like structure, for example, injection molded polyethylene terephthalate. A method of manufacturing the aforesaid bottle includes the steps of forming the outer supporting wire-frame structure, inserting a preform therein and blow-molding the preform within the supporting wire-frame structure to form the bottle of defined size and shape.
