Abstract: A process for making a bottle of a polymeric material suitable for being used with carbonated drinks, comprising the steps of: positioning a preform in a mould; and blowing the preform. The process is characterized in that a total draw ratio greater than 16 is used.
Abstract: A method is for manufacturing a container (C), such as a PET bottle, with a convex bottom and a self-bearing support, typically a self-bearing label. In particular, the method is for manufacturing a container (C) with a convex bottom and a self-bearing support including providing a plurality of containers (C) having a convex bottom. A machine (100) is provided for applying strips made of flexible material to the containers (C) and a plurality of support elements (1, 101, 201) for the containers (C). The support elements (1, 101, 201) are strips made of a support material. The method further includes feeding the plurality of containers (C) to the machine (100) and applying a support element (1, 101, 201) to each of the containers (C).

Abstract: 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.
