    摘要: In a nib structure of a writing instrument of the type having a tubular nib fitted to a forward end of a tubular tip of the instrument, the tubular nib is provided with a concentrically reduced diameter portion having an outer surface gently sloped from the ends toward a middle portion of the nib, and a radiused peripheral edge at a rearward end of the nib. The nib structure provides easy and accurate fitting of the nib into the tubular tip.

    摘要: A writing instrument comprises a writing nib having a writing tip at one end and an enlarged head portion at the other end, and a resilient seat urging the head portion of the nib toward a tip of the instrument. The nib is movably secured in a nib holder body in such a manner that a writing pressure enables the nib to move backward against the resilient force of the seat to form an ink-feed space between the head portion and the nib holder body. When the writing instrument is not in use, the head portion is engaged with the nib holder body to close the ink-feed space.
