Title:
STRETCH BLOW MOLDED CONTAINER
Document Type and Number:
WIPO Patent Application WO/2001/083197
Kind Code:
A1
Abstract:
A stretch blow molded container formed by stretch blow molding of a preform comprising a thermoplastic polyester as a main component, characterized in that the trunk, bottom and shoulder portions thereof are stretched and oriented, and further at least the central part of the bottom portion shows, in the measurement of differential scanning calorimetry (DSC), an endothermic peak (B) due to the disappearance of a quasi-crystalline state at a temperature region which is higher than the glass transition point of the polyester and lower than the starting temperature for the melting of crystals of the polyester. The container is formed by biaxial stretch blow molding of a thermoplastic polyester and has such excellent resistance to heat optionally with pressure that is sufficient to endure the sterilization by heat such as hot charging.
