ABSTRACT:
The disclosure illustrates and describes a sterilization apparatus and method for sterilizing the interiors of paperboard containers, wherein such apparatus and method are effective through the mandrel assembly on which the container bottom closures are formed and sealed. This is accomplished by forming longitudinal channels through each mandrel and connecting same to separate compartments formed within the hub, and providing means for communicating a suitable sterilant fog through respective compartments and channels at the station where each bottom-formed container is stripped from its respective mandrel. The usual fast stripping action tends to create a vacuum within the container which aids the dispersement of the fog onto the entire inside surface of the container, sterilizing it prior to the subsequent filling operation.
