Abstract
A refillable reservoir, particularly an ink converter for a fountain pen, has a cylinder in which a piston is slidable, and an actuating device for displacing the piston for refilling the ink chamber. Without needing to be detached from the piston, the actuating device can be stored substantially within the length of the chamber. The actuating device can be a rod which is disengageable from and slidable through the piston. Alternatively the actuating device can be a flexible ribbon coupled to a sleeve slidably mounted on the cylinder.
