ABSTRACT:
A disposable ink reservoir cartridge which is attachable to tubular writing pens of the stylographic type embodying a pressure compensating chamber. The reservoir cartridge is characterized by its axial deformability, such that the free volume of the reservoir may be reduced, as ink flows from the reservoir into the pressure compensating chamber during pen use. The reduction in free volume of the reservoir eliminates available air space and, thereby, avoids the deleterious effects of air pressure changes upon the ink or writing fluid, as the reservoir is depleted.
