Abstract

An ink cartridge includes a container defining at least one reservoir in which ink is receivable. An end molding is arranged at a first end of the container. The molding is breached, in use, by a mating formation of a printhead for facilitating flow of ink from the container to the printhead. A seal arrangement is arranged at an opposed end of the container. The seal arrangement includes a pellet of gelatinous material received in each reservoir. The pellet is of a consistency which retains its shape as it is drawn towards the first end of the container as ink is withdrawn from the container, in use.
