Abstract
A method of making a replaceable ink cartridge uses a molded, one-piece container body with an open bottom, elongated front, back and top walls, two side walls providing major surfaces of the cartridge, and a partition attached to the side walls and extending from the top wall toward the open bottom to divide the container body into first and second compartments. A sponge-like absorbent material is inserted into the second compartment through the open bottom, which is then sealed with a bottom wall, so that the cartridge has first and second chambers communicating with each other through an opening formed by a gap between the partition and the bottom wall.
