Packaging, particularly aseptic packaging of aseptic products in cartons

摘要

An aseptic packaging machine includes a chain conveyor conveying cartons along a path in an aseptic chamber including an advance leg and a return leg each along the machine. Ultra-violet germicidal lamps extend over at least a major portion of the advance leg. Aseptic liquid is fed into the cartons by a filling device comprised of, in turn, an expansion chamber, a non-return inlet valve, a reciprocatory bellows and a non- return valve. After filling, the cartons are top-sealed. The only non- aseptic matter deliberately introduced into the chamber is the cartons. The chamber is cleaned internally by cleaning fluid from spray nozzles. The carton entry to and exit from the chamber have aseptic air curtains.
