ABSTRACT:
A returnable/refillable container in the form of a blow molded polyester biaxially oriented bottle having a physical and structural relationship providing for the maintenance of aesthetic and functional viability over a minimum of twenty trips wherein each trip comprises (1) an empty state caustic wash followed by (2) contaminant inspection and product filling/capping, (3) warehouse storage, (4) distribution to wholesale and retail locations, and (5) purchase, use and empty storage by the consumer followed by return to a bottler. The container is obtained utilizing a specific preform configuration and reheat blow process wherein the sidewall of the resultant container has a percent crystallinity of 28-30 at a total preform draw ratio of 7-9/l. The container is formed utilizing recently developed process techniques to optimize strain induced sidewall crystallization.
