ABSTRACT:
An improved drainage tank assembly for a metered dispenser which includes a metering tank secured within a mounting cup, the mounting cup adapted to be secured to a container. The drainage tank includes a sealing portion which seals the interior of drainage tank from the mounting cup to prevent both corrosion of the mounting cup and contamination of the product dispensed. The drainage tank further includes radially extending ribs which extend from an interior surface of the drainage tank toward an outside surface of the metering tank to limit axial displacement of a band seal mounted on the outside surface of the metering tank.
