Abstract
An improved ink cartridge dispensing valve system for use with a printing press ink cartridge is provided. The valve system works on the same principle as a ball valve to automatically dispense ink when subjected to pressure. The valve system includes an attachment post and an attachable nozzle. The attachment post is an integral part of the dispensing end of the ink cartridge and is recessed so that the cartridge can be easily shipped without damaging the attachment post. The attachable nozzle fits over the attachment post and opens or closes depending on whether pressure is placed on it by the ink in the cartridge.
