ABSTRACT:
A method and apparatus for sterilizing preformed cartons prior to filling is disclosed. The interior of the cartons are first sprayed with a solution of hydrogen peroxide. The cartons are then treated with heated air to remove the hydrogen peroxide. The heated air is applied by means of a hollow mandrel having nozzles at one end. The mandrel corresponds generally to the shape of the carton. When the mandrel is inserted in the carton, air is directed against the interior side walls and bottom of the carton, and is exhausted from the carton by flowing upwardly between the side walls of the mandrel and the side walls of the carton.
