MARKING PEN WITH THREE PHASES OF INCREASING CAPILLARITY

摘要

MARKER WITH THREE PHASE INK CIRCUIT Marker includes a 3-phase ink circuit to transport ink from a large capacity reservoir through an intermediate capillary phase to a generally porous writing tip. Each phase of the ink circuit contains capillary ink transporting material. Arrangement of the phases in order of increasing capillarity draws ink from the low capillarity reservoir through a small diameter intermediate conduit to the generally porous writing tip.
