  • Publication number: 20090015642
    Abstract: A liquid storage container includes a liquid containing body that is formed of a flexible film and contains liquid therein; a liquid lead-out member connected to the liquid containing body; and a spacer member disposed in the liquid containing body. The liquid containing body deforms in a direction in which inner wall surfaces of the flexible film facing each other are brought into contact with each other at the time of reduction in the remaining amount of the liquid as the inside liquid is taken out through the liquid lead-out member, and the spacer member regulates contact between parts of the inner wall surfaces of the flexible film facing each other at the time of reduction in the remaining amount of the liquid to thereby form a remaining liquid space where liquid remains.

  • Patent number: 7399003
    Abstract: A plurality of cylindrical port defining portions project from a passage defining member defining a plurality of passages. A supply line defining body defining a plurality of supply lines is formed of an elastic member. The supply line defining body includes a plurality of openings each communicating with a corresponding one of the liquid supply lines. Each of the port defining portions extends perpendicularly to the direction in which each of the passages extends. Each of the openings extends perpendicular to the direction in which each of the liquid supply lines extends. A securing member fastens the port defining portions with respect to the corresponding openings collectively, by applying fastening force to the passage defining member and the supply line defining body in the axial direction of each port defining portion.
