ABSTRACT:
A biaxially stretch blow-molded article, particularly adapted for hot fill applications, having an improved bottom configuration. The bottom has grounding bottom portion and a central inwardly concave dome inside of the grounding bottom portion. The central inwardly concave dome has annular flat walls at different levels from the grounding bottom portion. The annular flat walls are defined by polygons of similar figures. An angle of one of the polygons is aligned along a radial line connecting a bisected point of one side of an adjacent upper or lower polygon and the center of the central inwardly concave dome. The angles of the polygons are the highly stretched areas having a high latitudinal stretch ratio, while the sides of the polygons particularly around the center point, are the moderately stretched areas. The highly and the moderately stretched areas are alternately arranged around the central inwardly concave dome in the circumferential and radial directions.
