CONICAL NIB, AND WRITING UTENSIL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To form a nib among parts which constitute a writing utensil, with a synthetic resin material employing engineering plastic.SOLUTION: An ink supply wick 39 includes a wick cover 49. An outer shape of a wick cover 49 is determined such that it is attached to an outer periphery of the ink supply wick 39 between the nib 1 and the ink supply wick 39 and is made to closely adhere to an inner periphery of the nib 1 at least at the tip of the nib 1. A space between the nib 1 and the ink supply wick 39 is filled with the wick cover 49. The nib is made of the synthetic resin material employing the engineering plastic. Therefore, the nib wear resistance and duration of the nib or the writing utensil can be extended.
