Patent KR-810001461-B1 (KR)
Title: Fountain pen with ink refill carrier
Inventor: HOCQ R
IPC: B43K5/14
Filed: 1978-10-25
Granted: 1981-10-23
Abstract: Ink cartridge retainer comprises spring cap for use with pens of elliptical or polygonal cross section.  A fountain pen (1) has a replaceable ink cartridge (4) retained by a cap (12).  The cap (12) has two internal leaf springs (16) which engage slots in the base of the cartridge.  The springs are forced outwards by a small lever (14) which is pivoted on a transverse pin attached to the body of the fountain.  When the lever is swung outwards it serves as a grip to facilitate the withdrawal of the cartridge.  This type of cartridge retainer eliminates the need for a screwed cap and so can be used with pens of elliptical or polygonal cross section
