It is known to fill containers while they are arranged in a space that is separated from the environment by a housing. It is also known to expose the containers to laminar flow of sterile air directed from the top down while the containers are in this space. Doing so helps to avoid contamination of the containers with foreign particles, such as dust, germs, or other unwanted substances.
It is also known to have transport sections between container handling machines or assemblies. These container-handling machines convey containers from one container-handling machine to a subsequent container-handling machine along a container-transport direction. A disadvantage of known transport sections is that any empty containers, or containers that have bee filled but not yet sealed, remain un protected against contamination while being transported along a transport section.
