Device and method for producing plastic containers and plastic containers produced by said method

Device for moulding plastic preforms into plastic containers, comprising:

• a blowing mould with an inner wall facing the plastic container, which blowing mould has a cavity within which a plastic preform can be formed into a plastic container, the blowing mould having a base part to form a base section of the container, said base part comprising a structuring section delimiting said cavity and forming part of the inner wall, said structuring section serving to structure the base section of the container, the structuring section being adapted to a shape of the base section of the finished container, the structuring section having a protrusion in a central region, said protrusion extending in the direction of the cavity and being arranged such that during an expansion process the protrusion lies on an injection point of the container;
• a filling device to supply a gaseous medium to the plastic preform via a mouth of the preform in order to expand the plastic preform inside the blowing mould;
• and
• a rod-like body which is mobile in relation to the blowing mould to stretch the plastic preform during the moulding process,
• wherein the inner wall of the blowing mould facing the plastic preform can be heated at least in sections.
