Abstract
A plastic preform for forming blow molded plastic containers wherein the inside wall face of the tubular body portion adjacent the bottom structure and extending onto the bottom structure has a plurality of faces with terminal portions thereof. Scallop-shaped segments are provided connecting the terminal portions of each face to initiate deformation prior to deformation of the faces and thereby have an increased rate and degree of orientation.
