Abstract
Method and device for producing containers which are filled with a liquid filling substance from parisons made from a thermoplastic material, wherein the respective parison is at least conditioned thermally and is subsequently shaped into the container during a shaping and filling phase in a mould by way of at least one liquid filling substance as pressure medium, and wherein, while it is being shaped into the container, the prison is preferably guided at least temporarily through a stretching rod and is stretched in the axial direction.

A method for producing containers made of a thermoplastic material filled with a liquid filling substance from parisons, comprising the steps of:
- thermally conditioning the respective parisons;
- and subsequently shaping each parison in a mold having at least one liquid filling substance as a pressure medium in the container during a shaping and filling phase, wherein the parison is, during shaping, in the container, at least intermittently fed through a stretching rod and stretched in an axial direction, wherein the filling substance or portions of the filling substance are introduced at least at two points in time and/or in at least two process phases with different proportions of carbon dioxide and/or at different temperatures.
A device for manufacturing containers filled with a liquid filling substance from parisons out of a thermoplastic material, comprising:
- a heating section for pre-heating the parisons;
- at least one shaping and filling station possessing a mold;
- at least one supply device for supplying the filling substance;
- and a carbonation unit for introducing or dissolving carbon dioxide, at least in a partial current of the filling substance, wherein said at least one shaping and filling station is constructed with at least one valve assembly, via which the filling substance or portions of the filling substance are introduced into respective parisons or the containers taking shape at least at two points in time and/or in at least two process phases with different proportions of carbon dioxide and/or at different temperatures.
A device for manufacturing containers made from parisons filled with a liquid filling substance from a thermoplastic material, comprising:
- a heating section for pre-heating the parisons;
- at least one shaping and filling station possessing a mold;
- at least one supply device for supplying the filling substance;
- and a carbonation unit for introducing or dissolving carbon dioxide is provided at least in a partial current of the filling substance, wherein the shaping station includes a guiding assembly formed as a stretching rod which, at least intermittently, exerts pressure on the parison while the parison is being shaped in the container and at least a portion of the filling substance can be conducted in an interior of the stretching rod, wherein outlet openings are provided at least at a lower end of the stretching rod.
