Abstract: A liquid container comprises an inner wall (102) that forms the liquid containing portion to contain liquid therein; an outer wall (101) that forms the container to contain the liquid containing portion therein; and a liquid supply portion for supplying liquid from the liquid containing portion to the outside. Then, the inner wall is arranged to be a member to generate negative pressure in the liquid containing portion by being deformed following the leading-out of the liquid, and also, formed by the material having an elastic modulus change of 25% or less against the temperature change of use environment. With the liquid container thus structured, it is possible to implement the stable supply of liquid by stabilizing the characteristic of negative pressure in the liquid containing portion thereof irrespective of the temperature changes of use environments.

Abstract: A fiber body which exhibits sufficient ink supplying characteristics for keeping up with the trend toward diversification of ink and high printing speed while ensuring an easy and simple ink injection operation and a liquid container having the same. The ink tank 1 has a PP fiber body (crosshatched area of the figures) 2, as a negative pressure generating member for an ink jet head which ejects liquid to perform recording, arranged almost all over the interior thereof, so as to allow the fiber body to hold a liquid to be supplied to an ink jet head. On the top of the tank casing, provided is an atmosphere communication port 3. And as a PP fiber body 2, used is an assembly of intertwined PP fibers of which surface has been subjected to surface treatment of giving hydrophilic nature thereto.

Abstract: An ink absorbing body stores an ink injected into an ink tank for an ink-jet with capillary force between fiber. On a surface of said fiber before filling the ink, a surfactant is deposited within a range of 0.002 to 0.2wt% relative to a weight of the ink or in a range of 0.01 to 0.5wt% relative to a weight of the fiber.

Abstract: The invention provides a liquid container capable of supplying ink to the exterior until the ink is almost depleted, and allowing simple detection of the remaining ink amount and deviated distribution of the ink component after a prolonged standing. The liquid container is provided with a first connection port and a second connection port on the bottom, communicating with a liquid chamber. The connection port is positioned closer to the end of the container bottom, while the connection port is positioned closer to the center thereof. In the connection ports, elastic members are provided so as to prevent leakage of the ink in the liquid chamber.
