ABSTRACT:
A marking device is disclosed wherein a pen-type device is utilized to store and enable markings to be produced from a dye suspended in a suspension medium such as water. The dye is of the heat sublimatible type and is finely ground and maintained in suspension by rolling action of a ball trapped within a reservoir defined by the pen body. A primary chamber is positioned adjacent the reservoir and a porous marking element is in turn frictionally and slidably positioned in the primary chamber. Valve means normally urged to a closed position enables ink to move from the reservoir into the primary chamber when the valve is caused to open, as by pressure against the marking element.
