ABSTRACT:
A housing assembly for a writing instrument is provided comprising a long, hollow barrel member and a ferrule member assembled in end-to-end relationship to afford an inner chamber for a reservoir of marking fluid. A writing nib projects from the ferrule and extends into the reservoir.
The ferrule member and the barrel member have adjacent skirt portions in telescoping assembled relation for normally mechanically urging the ferrule and barrel together in axial alignment. Additionally, the skirt portions, when moved longitudinally one into the other, afford fastening means, sealing means and means for constraining relative rotation between the assembled ferrule member and the barrel member thereby providing a securely sealed and easily assembled housing for a writing instrument.
