  • Patent number: 5482191
    Abstract: A device for filling a writing utensil having an applicator tip for applying a liquid has a container for receiving a liquid. The container has an air inlet connection to connect the interior of the container to a surrounding atmosphere and further has an opening. A receiving member for receiving the writing utensil or a liquid reservoir of the writing utensil is provided, wherein the receiving member is sealingly connected within the opening. A capillary liquid conveying connection, having a first and a second end, for conveying the liquid from the container into a writing utensil or a liquid reservoir of a writing utensil is provided. The first end opens into the receiving member and contacts the writing tip of the writing utensil or the inlet of the liquid reservoir of the writing utensil. The air inlet connection has at least one chamber.

  • Patent number: 5102251
    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.
