Plastic bottle with flexible base section

Abstract

The invention discloses a plastic bottle with a flexible base section. The plastic bottle comprises a base section, a middle section and an opening section, wherein the opening section is provided with a thread; the cross section of the opening section is smaller than the cross section of the middle section; according to the invention, the base section comprises a peripheral platform area and a center area distributed in an inward radial form relative to the peripheral platform area; the center area is provided with an annular section and a flat section or a dome-shaped section; the flat section or the dome-shaped section is arranged in the inward radial form relative to the annular section and is raised along the direction away from the opening section relative to the annular section; the base section further comprises a transition area; the peripheral platform area is connected with the center area through the transition area; the transition area at least comprises a bent first sub-area and a bent second sub-area; the first and second sub-areas have different radiuses of curvature in sections; the bent first sub-area is arranged in the inward radial form relative to the bent second sub-area; at least one sub-area is flexible.

Description

technical field [0001] The invention relates to plastic bottles, especially plastic bottles designed to be filled with a liquid medium, such as a cold medium, especially a beverage. Background technique [0002] The variability of plastic bottles is well known in the art. Since the bottle is filled with a (liquid) medium (cold or hot), the following problem occurs after the filling and capping process: the liquid shrinks and therefore the internal volume of the filled bottle decreases (or the internal volume of the bottle when the beverage expands increase). Therefore, it is necessary to avoid deforming the standard bottle. Generally, this is caused by shrinkage of the headspace and / or vacuum created by the product; wherein the headspace is caused by temperature changes that occur between filling and storage, and by pressure changes from the point of filling to the point of dispensing or consumption shrink. [0003] In the above case, the container will have to resist th...
