Abstract
The invention relates to a method and device used to blow-mold containers. After thermal conditioning, a preform is shaped into the container inside a blow mold by the effect of blowing pressure. Required blowing gas is introduced into an interior of the preform through a connecting element. After the blow-molding, a purging gas is conducted through the interior of the container. A plurality of blowing stations are used, and, for at least one of the blowing stations, at least part of the required amount of the purging gas is stored in a storage volume associated only with said blowing station.

A method for blow molding containers, comprising the steps of:
- thermal conditioning a preform;
- deforming the preform into a container within a blow mold arranged in an area of a blow molding station using blowing pressure;
- conducting blow molding gas through a connecting element into an interior space of the preform;
- after the blow molding, conducting a rinsing gas through the interior space of the container, the method including using a plurality of blow molding stations;
- and, for at least one of the blow molding stations storing at least a portion of a required quantity of rinsing gas in a storage volume assigned exclusively to the blow molding station.
A device for blow molding containers, comprising:
- at least two blow molding stations each with at least one blow mold;
- a connecting element having a flow path for a blow molding gas to form the containers;
- and a device for supplying a rinsing gas, the blow molding stations being connected to the device for supplying a rinsing gas, wherein at least one of the blow molding stations is connected to a storage for at least a portion of the rinsing gas, the storage being exclusively assigned to the at least one blow molding station.
