Abstract
An apparatus is provided for cleaning residual powder and other contaminants from external surfaces of pressed powder cosmetic pans before the pans are adhered into the compact. A feed chute feeds pans into a feed path in the apparatus one after another in an upright orientation. The feed path includes two cleaning stations, each provided with brushes for scrubbing the pan. One cleaning station has cylindrical or drum brushes to scrub the bottom of each pan. The other cleaning station has a belt-type brush to scrub the sides of each pan. Dust collection systems are suspended above and below the apparatus at appropriate locations along the feed path to collect the residual powder and contaminants removed from the pans. Belts may be provided within the feed path to move the pans through the cleaning stations.
