Abstract
An additive overflow reduction system for an automatic vending machine of the hot beverage type which has storage containers for additives such as dry creamer arid sugar and which feeds the additives to a mixing bowl by use of an auger-type feed mechanism. The system includes a reduced area outlet and a minimized volume of product retained adjacent the outlet to allow as little volume of product as practicable to remain in the area of the opening after material has been feed from the opening. A portion of the last flight of the auger is disposed perpendicular to the axis of rotation of the auger to reduce the force on the retained product that would otherwise tend to force the product out of the opening if the machine is vibrated or bumped.
