Abstract: An improved ink cartridge of the type used to dispense ink in automatic lithographic presses. The ink cartridge comprises a hollow cylindrical body for holding a supply of extrudable ink, a plunger and a dispensing fitment. The improvement comprises a valve member mounted over a central aperture in the dispensing fitment and a flexible molded plastic spring that biases the valve member in the closed position. The valve member opens when subjected to pressure from the ink and closes automatically and completely when the ink pressure is less than the biasing force of the flexible spring.

Abstract: A one-piece dispensing top has three separate dispensing ports. Each dispensing port is designed to dispense particulate foodstuffs from a container. One port is configured to allow removal of product with an utensil. A second port is configured to be used for pouring product and includes a spout, and a third port is configured for sifting product. Each dispensing port includes a closure flap for sealing. All three closure flaps are integrally joined to the dispensing top via living hinges. The closure flaps may be retained in the closed position by a friction or snap fit.

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.
