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.
