Abstract
The subject invention is directed to a cartridge for a writing instrument. In particular, the writing instrument includes a surface against which the cartridge abuts. The cartridge includes a tubular body for containing ink which has a front end including an applicator for applying the ink, and a plug member disposed at least partially in a rear end of the tubular body of the cartridge. The plug member includes a path for permitting airflow into the tubular body, and a flange for cushioning the cartridge against the abutment surface of the writing instrument so as to inhibit separation of the ink from the ink applicator and absorb pressure exerted upon the ink applicator during writing.
