ABSTRACT:
The problems of excess flow of a liquid to be dispensed in a metering device, especially for a sterilizing liquid for packings and packaging materials, is solved by pumping the liquid from a supply vessel below the housing of the metering device into the latter and maintaining a bath of the liquid in the latter by overflow back to the supply vessel. A control slider lifts a quantity of the liquid from the bath to an overflow channel from which it flows to a metering chamber and then passes through an upwardly inclined duct to the atomizing and blowing device applying the liquid spray to the packaging materials.
