Summary:A new profile of the internal neck that, instead of being simply cylindrical, presents an internal ring in proximity to, and at the height of, the support ledge plain and to which corresponds a specific profile in the area under the support ledge. These profiles allows a ring to be created of different shapes and geometries (SWERVE SHAPE) using the internal material between the support ledge and the area under the support ledge, thereby re-enforcing the neck and avoiding oval formation (creating problems with sealing and loss of content) as well as deformation of the support ledge during the blowing process, without impacting weight reduction. This invention allows for ultra-light containers with good physical-mechanical behavior. A further reduction of the width(s) using present technologies is not permissible due to insufficient radial rigidity. This present invention permits the light-weighting of various types of containers of different prime materials.
