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 beverage container for a carbonated beverage may include a base with a plurality of feet extending therefrom. The feet may act to reinforce a punt in the base of the beverage container to prevent deformation of the base of the beverage container when a carbonated or other pressurized beverage is added to the beverage container.

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 bottle made of polymer material includes a base provided with a plurality of ribs. Each rib is composed of a curvature of the base of the bottle which forms a protuberance in the longitudinal direction directed towards the inside of the bottle. The ribs extend in a radial direction along a line of radial extension. The bottle is characterized in that the projection, in a transverse plane, of the line of radial extension of at least one of said ribs is curved.

Abstract: A bottle made of polymer material comprises a base (12) provided with a plurality of ribs (14). Each rib is composed of a curvature of the base (12) of the bottle which forms a protuberance in the longitudinal direction directed towards the inside of the bottle. The ribs extend in a radial direction along a line of radial extension (18). The bottle is characterized in that the projection, in a transverse plane, of the line of radial extension (18) of at least one of said ribs (14) is curved.

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.

Abstract: A parison of thermoplastic resin to be particularly used to be subsequently blow molded to become a plastic bottle has an upper portion (H), a middle portion (L) and an end portion (N). The middle portion has, on its lower side near the terminal portion, a lower sub-portion (M) which has a thickness that is variable and smaller with respect to the wall thickness of the parison in the middle portion, with a profile in the shape of a downward narrowing frustum of a cone. Preferably, the thickness in the lower sub-portion (M) is decreased by at least 12% with respect to the thickness of the remaining middle portion of the parison, and the angle between the sides of the profile in the shape of a frustum of a cone and the axis of symmetry is between 5° and 10°. The advantages are broader process tolerances, elimination of heat conditioning treatments, reduction in resin usage.
