ABSTRACT:
One disadvantage of a biaxially stretched, blow molded bottle of a saturated polyester resin, particularly polyethylene terephthalate, presenting many excellent features and physical properties, lies in its neck portion which is not subjected to stretching during the molding of the bottle, but which is inferior to its body portion in such physical properties and features. This disadvantage is eliminated by molding at least the neck portion of a parison for such a bottle from a biaxially stretched plate of the resinous material from which the bottle is molded, so that both the neck and body portions of the bottle are composed of the duly biaxially stretched material.
