A container () and a screwable closure () comprising a hollow body () and a neck finish () terminated by a wide-mouth opening (). Said neck finish comprises a neck support ring () and a neck portion () extending between the wide-mouth opening () and the neck support ring (). The neck portion () comprises an upper portion () and a reinforced lower portion (). The inner face () of the reinforced lower portion () is transitioning to the inner face () of the upper portion () along a transition step () in such a way that said reinforced lower portion () is thicker than the upper portion () at least in a top part of the reinforced lower portion (). The neck support ring () is below the removable closure ().

A hot-fillable plastic container includes a base and a body extending upward from the base. The includes a deformable cylindrical sidewall portion defining a central vertical axis, wherein the deformable cylindrical sidewall portion comprises at least two vertical pillars arranged along the body circumference. Each vertical pillar is joined to the next vertical pillar by a generally concave deformable sidewall panel having a concave arc-shaped transverse cross section of curvature radius. The curvature radii of the vertical pillars are smaller than the curvature radii of the generally concave deformable panels, and each transition between a vertical pillar and a generally concave deformable panel is smooth without any convex portion. The large curvature radius of each generally concave deformable panel allows an inward deformation of each panel, and each pillar is slightly pushed outward and is slightly deformed with a small reduction of its curvature radius, under the vacuum created inside the container by the volume reduction of a hot-filled product during cooling.

The present invention relates to an aromatic polyester composition for making stretch blow molded containers with improved strain hardening. The polyester composition according to the invention exhibits a low DEG content, a natural stretch ratio of &#x3c;10, a half time of crystallization of &#x3e;150 sec at 200&#xb0; C. and comprises a sulfo-modified copolymer. Compared to polyesters of the prior art, the polyester of the present invention exhibits superior stretching characteristics, such as a lower natural stretch ratio (NSR), which allows for production of small PET bottles via thinner and longer parisons. Such thinner and longer parisons improve the production of small containers due to shorter cooling cycles.
