Abstract
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.
