Abstract
This relates to the base configuration of a biaxially oriented blow molded thermoplastic resin container. It has been found that by assigning more space to the ribs between adjacent legs and feet, during the blow molding of a preform, there is proportionally less thinning of the material of the preform in accordance with the greater width of rib, thereby providing greater strength in the high stress area of the base structure with a resultant lesser failure due to stress cracking.
