Abstract
An extrusion blowmolded PET container having superior top load strength characteristics includes a sidewall having an outer surface, and an inner surface that defines an interior space. The sidewall is fabricated from a material that includes extrudable PET. The sidewall is shaped to define a bottom portion, a finish portion and a main body portion. The finish portion has an opening defined therein that is in communication with the interior space. The main body portion has a neck surface, a shoulder surface and a fillet that is defined between the neck surface and the shoulder surface. The neck surface forms a first angle with respect to a longitudinal axis of the container that is substantially within a range of about 2° to about 20°, and the fillet has an average radius of curvature that is substantially within a range of about 15 mm to about 55 mm. The container is preferably fabricated using an extrusion blowmolding process.
