ABSTRACT:
A sterilization apparatus and method for sterilizing the interiors of paperboard containers, wherein such apparatus and method are operative prior to the container being mounted on a mandrel assembly on which the container bottom closures are formed, closed and sealed. This is accomplished by providing nebulizing means for communicating a suitable sterilant fog through and onto the inside surfaces of the carton blank immediately after it has been removed from a magazine and opened into a four-sided tubular shape, thereby greatly increasing the total interior sterilizing time available prior to the container being filled, as compared to conventional sterilization processes which are operative after the bottom panels of the carton have been closed and sealed.
