Abstract
A cartridge-type fountain pen is formed at its rear end with a reserve compartment for receiving a reserve ink cartridge or a liquid applicator reservoir whose applicator is designed to project through an opening end of the rear end of the barrel. A second cap can be pressed on this rear end and has a rear cap member spring biased into engagement with the reservoir and whose position is visible through a window in an outer cap member of this second cap so that the user can ascertain whether or not the liquid applicator is in place within the reserve compartment.
