Claim:
A mechanism for sealing a cover to a container for storing ink in an inkjet cartridge, comprising: a container for storing ink having an inside surface, an outside surface and a peripheral edge of the outside surface adjacent to an opening of the container; a cover having an inside surface, an outside surface and an extension member extending from the cover in a direction substantially along the outside surface of the container and substantially perpendicular to a direction that the inside surface of the cover extends, the cover being structured so as to fit over the container so that the extension member is peripherally outside the outside surface of the container and a space is formed between the outside surface of the container at substantially the peripheral edge of the outside surface of the container and a surface of the extension member of the cover that faces toward the container when the container is closed; and a gasket situated in the space such that when the container is closed the gasket is disposed between and in contact with the outside surface of the container at substantially the peripheral edge of the outside surface of the container and the surface of the extension member of the cover that faces toward the container.
