RESERVOIR PENS AND INK CARTRIDGES THEREFOR

摘要

An ink cartridge (1) for a reservoir pen has a body (2) which encloses an in k- chamber (3) that is initially sealed near the front end of the cartridge by a closure formed by a plug (4). The plug (4) sealingly engages in an axial bor e (5) which is open to the front end of the cartridge and is slidably mounted in the cartridge body (2) so as to be moved rearwardly by engagement with a peg (34) upon insertion of the cartridge (1) into a pen, thereby allowing ink fl ow from the ink chamber (3) through the bore (5) and to a writing tip (23) of a nib (22) of the pen. The peg (34) is sized so as to form a seal with the inn er surface of the bore (5) when fully inserted thereinto.
