Title: Writing utensil
Inventor: TAMAI ATSUSHI
IPC: B43K8/02
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To prevent a handwriting from being patchy by forming an air venting part on the periphery of an ink relay refill. SOLUTION: When air bubbles are trapped in an ink relay refill 8, ink penetrates the ink relay refill 8 by sliding a tip holder 9 to open the slit of an elastic valve 11 and the air bubbles are pushed out into an air venting part 11 by the head pressure of the ink. In this case, the air venting part 11 is kept in the equilibrium state with an atmospheric pressure, even when the air is pushed out as the part 11 communicates with the atmosphere. Consequently, the internal pressure of an ink tank or an ink flow path is not influenced. The air penetrating the interior of a pen point or the ink relay refill 8 is easily pushed out into the air venting part which is a space formed in the peripheral part of the ink relay refill 8 without the necessity to push out the air as far as the ink through hole of the pen point.  Thus the continuous smooth ink supply is achieved without being blocked by the air bubbles even when the ink is supplied from an ink storage part filled with the ink with a low head pressure.
