Abstract
An improved cartridge for dispensing highly viscous fluids in which the nozzle is recessed for ease of packaging, shipping and storing. The cartridge comprises a hollow cylindrical body, a plunger and a dispensing fitment. The cylindrical body holds a supply of extrudable fluid contents such as lithographic ink. The plunger serves as a pneumatically activated piston within the cylindrical body to extrude the contents of the cartridge. The nozzle has an open and a closed position. In the closed position the nozzle does not protrude beyond the top of the dispensing fitment. The dispenser may also include a detachable nozzle extension which, when attached to the nozzle, extends beyond the top of the fitment.
