INK CARTRIDGE WITH SEALING MEANS FOR RECIPROCAL PRINTING HEADS

摘要

An ink supply for a film marking apparatus from which a fast drying ink is obtained for prolonged periods of time without recharging. Recharging is accomplished by replacement of an ink storage container having a foam-like filler spaced from a closed end and exposed to a marking device at an open end through a porous pad and a restricted opening in a porous closure disk.
