ABSTRACT:
Apparatus and method for cleaning container closures during downward travel in an elongated vertical pathway from a hopper to a capping machine. The apparatus includes liquid and gas spray means for directing generally horizontal fluid streams against vertically oriented inner surface portions of the closures, an enclosure, and a drain for removing liquid from the enclosure. A belt means engages closures traveling through the apparatus, thereby forcing the closures past the liquid and gas spray means and controlling their rate of travel. In a preferred embodiment, the belt means comprises several laterally spaced flexible endless belts each having a principal section frictionally engaging outer surface portions of the closures. An additional feature of the preferred embodiment is a perforated plate adjacent an interior surface portion of the principal section.
