Abstract
A carton filling machine comprising a compartmentalized clean air system for providing a downward unidirectional flow of clean air into a chamber that substantially encloses one of the machine stations is provided. Preferably, the machine station is a filling station. Even more preferably the clean air system encloses both the fill pipe of the filling station and a top folding portion of a top sealing station of the machine. The top folding portion of the top sealing station ensures that the carton exits the chamber in a closed state whereby the carton is maintained in a very hygienic state after it has been filled in a very hygienic atmosphere. The air flow is advantageously divided into plural streams, one of which is directed about the fill pipe to further ensure sterile filling conditions.
