Plastic container with a base section, with a main body adjoining the base section in a longitudinal direction of the container forming an inner volume of the plastic container wherein the base section forms a plurality of standing foot areas, wherein a tension band extending in a radial direction is disposed between two adjacent standing foot areas, and the base section has a first curved structure with an injection point such that that the injection point projects in the longitudinal direction of the plastic container towards a mouth of the plastic container and a second curved structure adjoins the first curved structure outwardly in the radial direction, wherein this second curved structure is curved in the direction of the mouth of the plastic container, wherein a radius of curvature of the first curved structure is smaller, at least in sections, than a radius of curvature of the second curved structure.

Plastic container for holding beverages with improved stability

A blow mould for forming plastic preforms into plastic containers, having at least two blow to mould side parts and a base part, which form a cavity, within which plastic preforms can be formed into the plastic containers by being acted upon by a flowable medium, wherein an inner wall of the blow mould side parts and of the base part having a contour which produces a predetermined shape of the plastic containers to be produced, wherein a plurality of openings being provided in at least one section of the base part, which openings allow a gaseous medium to be discharged during an expansion process of the plastic container. A ratio between a surface area of the base part and a surface area of the openings is 3-350, preferably 4-200, and particularly preferably 3-100.

A one piece plastic container for beverages, has a base region, a main body extending in the longitudinal direction of the plastic container to the base region and a mouth region with a container mouth, with the mouth region adjoining the main body in the longitudinal direction at least indirectly, wherein the base region has at least three standing feet, wherein at least one groove having a groove base extending in the circumferential direction over a circumferential angle is arranged between two, in particular adjacent feet. The wall of the container is curved inwards at least in sections in the region of the groove base of a groove.

Plastic container with tension band geometry at base region

A method is described for shaping the bottom of hot-filled containers, in which the bottoms of the containers are forced inwardly from a state bulged outwardly, in particular as they cool down. Complex mechanisms for forcing the bottom inwardly are dispensable for the reason that the bottoms are forced inwardly by at least one fluid jet and/or fluid pressure wave. In addition, shaping the bottom can advantageously be carried out in a production region immediately downstream of a closer.

Method for shaping the bottom of hot-filled containers

A plastic container has a mouth portion, a main body, and a base portion which adjoins the main body. The base portion has a central region as well as a diaphragm which runs in a circumferential direction and extends from the central region to the main body. The central region is pivotable relative to the main body between at least two positions which differ with regard to an internal volume of the container. The wall has at least one and preferably at least two circumferential grooves and are spaced apart from one another. The central region has a projection extending in the direction of the interior of the plastic container, and at least one web extending at least in part in a radial direction in the circumferential wall.

Bottle neck

A container made from plastic for holding beverages. The container comprises a mouth, a wall section which adjoins the mouth in a longitudinal direction (L) of the container, and a base section which is designed as a standing face. The wall section merges into the base section. The container is formed in one piece. The base section has an injection point located in the interior in a radial direction (R) with respect to the longitudinal direction (L), and a central region which surrounds this injection point, and also a transition section which extends from the central region to the wall section. The transition section has a curvature with a finite radius of curvature in at least one and preferably in every radial direction (R) of the container in every geometric sub-section.
