Abstract

A heat-resistant and biaxially stretched blow-molded plastic container includes a base movable to accommodate vacuum forces generated within the container and thereby decrease the volume of the container. Embodiments of a container include a push-up portion, and first and second parting lines that are separated from one another by a gap and that extend on opposite sides of the push-up portion. Embodiments of such a container exhibit one or more of the following: (a) a distance between each parting line and the center of the base is not more than 20 mm; (b) a distance between the two parting lines is not more than 40 mm; and/or (c) a distance between the two parting lines is less than 50% of the transverse dimension of the base measured between the two outermost points of the parting lines. Methods for blow molding heat-resistant plastic containers are also disclosed.
