Embodiment Construction

[0091] Figure 1A A plan view showing an exemplary bottom of a container made of thermoplastic material. The container may especially be a plastic bottle, for example a PET bottle. Figure 1A The plan view in is in particular the plan view of the outer surface of the bottom side of the container, meaning the side of the bottle opposite the mouth of the bottle which is usually placed on a support surface such as a table.

[0092] The bottom comprises a first surface area 1 and a second surface area 2 . The first surface area 1 and the second surface area 2 each have a constant distance at a constant radius R relative to the longitudinal axis 4 of the container to a plane arranged perpendicular to the longitudinal axis, for example a table on which the container is arranged or placed Wait.

[0093]The first surface region 1 is offset from the second surface region 2 towards the interior of the container. In other words, the distance of the first surface region 1 to the suppo...

Abstract

A container of a thermoplastic material, in particular a plastic bottle, comprises a bottom comprising a first and a second surface area, where the first and the second surface area, at a constant radius with respect to the longitudinal axis of the container, each have a constant distance to a plane surface arranged to be perpendicular to the longitudinal axis, where the first surface area is offset with respect to the second surface area towards the interior of the container, where the first and the second surface area are connected by a third surface area which is embodied in the form of a coherent loop band and comprises at least three loops, and where the transition between the first surface area and the third surface area, and / or the transition between the second surface area and the third surface area are continuously differentiable at least once, in particular at least twice.

Description

technical field [0001] The present invention relates to containers made of thermoplastic material, in particular to plastic bottles. Background technique [0002] For example, containers made of thermoplastic materials are often used in the food industry as containers for liquid products such as beverages. The containers are usually formed from plastic preforms in blow molding machines or in stretch blow molding machines. For this purpose, plastic preforms are first thermally conditioned and then shaped into containers under pressure in so-called blow molds. [0003] The geometry of the containers thus produced often depends on the requirements placed on the containers by the product to be filled. Furthermore, consumers place demands on the containers, eg for weight or stability. [0004] An important part of a container is its bottom. The bottoms of plastic containers are often specially formed for high stability. A container with a bottom is known, for example, from D...
