BLOW-MOULDED BOTTLE-SHAPED CONTAINER OF BIAXIALLY ORIENTED POLYETHYLENE TEREPHTHALATE RESIN AND METHOD OF MOULDING THE SAME |
摘要 |
<p>A hollow blow-molded bottle-shaped container of a biaxially oriented polyethylene terephthalate which advantageously has a crystallized outer peripheral portion at the neck portion except the boundary between the neck portion and the body portion and non-crystallized inner peripheral portion thereat. This bottle-shaped container is molded by a method of molding the same, which method advantageously has the steps of injection-molding a piece or parison formed at the outer peripheral surface of a neck root part forming portion in a downwardly flared tapered shape, and crystallizing by a heat treatment the outer peripheral surface portion of the neck root part forming portion. Thus, the deterioration in the physical properties of the neck and shoulder portions of the bottle-shaped container thus finally blow-molded can be reduced.</p> |
