1. A method for producing filled containers from preforms made of a thermoplastic material, comprising the steps of:
- transferring the preforms in each case onto a molding and filling element of a molding and filling station; and
, in a subsequent molding and filling process, remolding the preforms into a particular container in a mold of the molding and filling station, which is in a molding and filling status in which a simultaneous molding and of the container is carried out under an effect of pressure of a supplied liquid filling material; and
, after the molding and filling, removing the container from the molding and filling element of the molding and filling station;
further including, before the molded and filled container is removed, transferring the molding and filling station into a safety status in which the particular mold is separated and protected from the molding and filling element, wherein there is a plurality of molding and filling stations on a transport element which is driven in a rotary manner, the switching of the molding and filling stations between the molding and filling status and the safety status occurs by a relative movement between the particular molding and filling element and an associated mold, the relative movement being radial to an axis of rotation of the rotating transport element so that in the safety status the particular mold is entirely radially spaced from the molding and filling element so that there is no radial overlap between the molding and filling element and the mold.

Abstract
A method and device for producing filled containers from preforms made of a thermoplastic material. The preforms are respectively transferred to a molding or filling element of a molding and filling station and are shaped in the respective container in a subsequent molding and filling process inside a mold of the molding and filling station due to the action of the pressure of a supplied filling material in the preform. The respective container is withdrawn from the molding and filling element of the molding and filling station after molding and filling.

10. A device for producing containers filled with a liquid filling material from preforms made of a thermoplastic material, the device comprising:
- a plurality of molding and filling stations having a mold and a molding and filling element, the molding and filling stations being arranged on a transport element driven in a rotating manner, wherein each molding and filling station has at least one molding and filling element by which, during the molding and filling, the liquid filling material is introduced into a particular preform and simultaneously into the container being molded so that the preform is simultaneously molded and filled with the liquid filling material, and at least one mold with a mold inner space having a contour that corresponds to a shape of the containers, wherein the molding and filling element interacting with the preform and the container during the molding and filling, and the mold are movable relative to one another in a radial direction with respect to an axis of rotation of the transport element to change a status of the molding and filling station between a molding and filling status and a safety status, in which the molding and filling element is entirely radially separated from the mold, wherein a switching of the molding and filling stations between the molding and filling status and the safety status occurs by a relative movement between the particular molding and filling element and an associated mold in a direction radial to the axis of rotation of the rotating transport element so that there is no radial overlap between the molding and filling element and the mold.
