ABSTRACT:
Capillary writing pen of the type embodying a cylindrical body having an open end and a pen tip with reservoir insertable as a cartridge within the cylindrical body. Particularly the improvement consisting of providing wave like complemental surfaces at the abutting interface of the cylinder open end and cartridge tip, such that transverse twisting of the cartridge with respect to the cylinder results in axial separation of the cartridge with respect to the cylinder. The improvement eliminates the necessity for the expensive and time consuming complemental threading of the cylinder interior and cartridge exterior and is readily producible in conventional plastic dies.
