Method and device for filling large containers

Abstract

A method for production of drink containers includes the steps of providing a compressed container, exposing the compressed container to a gaseous medium to expand this, wherein preferably during expansion a wall thickness of the container does not change by more than 10%, and filling of the expanded container with the fluid.

1 . A method for production of drink containers comprising the steps:
 provision of a compressed container,   exposure of the compressed container to a gaseous medium to expand this, wherein preferably during expansion a wall thickness of the container does not change by more than 10%,   filling of the expanded container with the fluid.   
     
     
         2 . The method according to  claim 1 , wherein the container is then unfolded by exposure to the gaseous medium. 
     
     
         3 . The method according to  claim 1 , wherein a cross section of at least one portion of the container remains unchanged during expansion. 
     
     
         4 . The method according to  claim 1 , wherein the container is compressed in a compression process before expansion. 
     
     
         5 . The method according to  claim 1 , wherein the container is a container produced by a blow-moulding process. 
     
     
         6 . The method according to  claim 1 , wherein the compressed container is expanded by a gas selected from a group of gases containing nitrogen and carbon dioxide. 
     
     
         7 . The method according to  claim 1 , wherein the container is evacuated before exposure to the gaseous medium. 
     
     
         8 . The method according to  claim 1 , wherein before exposure to the gaseous medium, a closing element for closing the container is removed from a mouth of the container. 
     
     
         9 . The method according to  claim 1 , wherein the container is filled with a fluid after expansion. 
     
     
         10 . A device for production of containers filled with fluids, with an expansion device which is suitable and intended for expanding containers, produced by a forming process and then compressed, by exposure to a gaseous medium, and with a filling device arranged downstream of the expansion device in a transport direction of the containers, which fills the expanded containers with a fluid.
