Abstract

A method and apparatus are provided for sonicating an article such that the liquid used as the sonication medium cannot recontaminate the article. A sonication medium in the form of a film of liquid is streamed over the article. A probe of a sonic horn is positioned in sonic energy transfer relationship to the sonication medium next to the article. Sound waves transmitted through the sonication medium dislodge particles from the article and into the sonication medium. The sonication medium carrying dislodged particles is drained away after passing the probe of the sonic horn. A subsequent sterilization means can be used to further clean the article. The article can be a web of packaging material used subsequent to sterilization for forming into individual containers for the aseptic packaging of foodstuffs or the like.
