ABSTRACT:
Cups or lids for packaging foodstuffs and the like in a sterile environment are sterilized in the packaging machine by passing them through a sterilizing chamber to be contacted first by the hydrogen peroxide and then by hot air. The packaging elements are initially moved apart rapidly and are than brought toward one another without contact, periodically in the sterilizing chamber to improve the contact of the sterilizing and drying fluid with the surfaces.
