ABSTRACT:
A plastic blow molded container (10) includes a hollow body portion (11), an upper dispensing end (14) having a dome (15) and spout (16), and a lower freestanding base (18). The container includes a main layer (19) of virgin polyethylene terephthalate that defines the upper dispensing end (14) and partially defines the hollow body portion (11) and the lower freestanding base (18), and the container also includes a gas barrier liner (20) that is located inside of the main layer (19) defining an inner container surface (20a) and that cooperates with the main layer (19) to define the freestanding base (18) and at least a portion of the body portion (11). The gas barrier liner (20) has an upper end (21) located below the dispensing end (14) and has a wall thickness that is less than 0.25 of the adjacent wall thickness of the polyethylene terephthalate main layer (19). The freestanding base (18) preferably has a central hub (22) as well as hollow legs (23) and curved ribs (24) positioned about the hub in an alternating relationship.
