Abstract
A supply system is provided for a device that operates with capillary forces and is used to apply liquids. The system includes receptacles that accommodate the liquid and are closed off relative to the atmosphere. Also provided is an application element that communicates with the receptacles via a feed mechanism and serves for the application of the liquid, for which purpose the application element has a discharge. Each of the receptacles is provided with an inlet and an outlet, with the receptacles being interconnected in the manner of a series connection by having the outlet of one receptacle communicate with the inlet of another receptacle. The capillarity of the inlets and outlets is greater than the capillarity of the receptacles in the vicinity of the inlets and outlets thereof, and is less than the capillarity of the discharge of the application element.
