Apparatus and methof for aseptically filling containers

摘要

Apparatus 20 for filling cartons 22 in a sterile, contaminant-free environment comprises an enclosure 26 which at least partially surrounds a carton filler nozzle 24. A carton opening 32 formed in the bottom of the enclosure 26 is shaped to receive an open-ended carton 22 into a position for filling. Guides 44 machined into interior surfaces of the enclosure 26 guide the motion of the carton 22 into the enclosure 26 for filling. A port formed in the enclosure 26 admits sterile fluid to flush the interior of the enclosure 26. The port and the nozzle 24 are connectible into a cleaning solution circuit with the port providing an outlet for cleaning solution that has entered the enclosure 26 through the nozzle 24. The nozzle 24 and the interior of the enclosure 26 may be cleaned by sealing the enclosure 26 from the ambient atmosphere and then flushing the enclosure 26 with the cleaning solution.
