Abstract
An ink container, such as that used in an ink jet recording apparatus, is improved to effectively suppress permeation of ambient air into ink compartments through the container walls and to permit easy refilling with ink. The ink container includes a container body which has a plurality of liquid compartments defined therein by a plurality of partition plates to accommodate the ink, and inter-compartment communicating portions through which adjacent ink compartments communicate with each other, so that successive liquid compartments are emptied one after another as the liquid is progressively consumed. The container body also has a buffer compartment which covers at least the top walls of said liquid compartments. The ink container may have a discrete segments of a porous member which are disposed only in the inter-compartment communicating portions.
