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 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;
• 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.

Method for moulding plastic preforms into plastic containers, comprising:

• arranging at least one plastic preform in a cavity formed inside a blowing mould;
• moulding said at least one plastic preform, within said cavity, into plastic containers by expansion against an inner wall of the blowing mould, the plastic preform being expanded against a structuring section of the blowing mould forming a part of the inner wall to form a base section of the container, a central region of the plastic preform being expanded against a protrusion formed on a structuring section and extending in the direction of the cavity;
• heating the inner wall of the blowing mould facing the plastic preform at least in sections for performance of the moulding process;
• and
• supplying a gaseous medium to the plastic preforms by means of a filling device during the moulding process.
