Abstract
A liquid storing container, having a liquid feed portion for supplying liquid to a liquid injection recording apparatus, includes a rectangular receiving case for a porous member, and a filter that compresses the porous member. The liquid storing container provides for controlled feeding of liquid through a contact portion where the filter compresses the porous member, and a proper balance of air and liquid is achieved by symmetrical surfaces located within the receiving case.
