Liquid packs provided with liquid leading members are stored in a container case that is constituted by fitting a case main body portion and a lid case in fitting portions and, support portions, which positions the liquid leading members so as to be opposed to liquid introducing members attached to a cartridge inserting portion, are provided on a front surface of the container case, the fitting portions are arranged in a state in which the fitting portions traverses the support portions, and space portions having a gap larger than a gap formed in the fitting portions are formed near the support portions in the fitting portions. In this way, liquid flowing through the fitting portions due to the capillarity is retained by the space portions and never flows to the fitting portions further extending from the space portions.

When ink is filled into an ink packincluding a bag partand an outlet part, firstly, air in the bagand outlet partis sucked by a suction pump Pprovided for an ink pouring apparatus. Further, by a first measuring pipe, ink supplied from a main tankis poured through the outlet partinto the bag part. Further, by a second measuring pipe, the ink poured into the bag partof the ink packis sucked and exhausted. Furthermore, the ink in the second measuring pipeis mixed into a mixing tankwith ink previously supplied to the mixing tankfrom the main tank. Next, the ink is supplied from the mixing tankto a third measuring pipe, and filled from the third measuring pipethrough the outlet partinto the bag part

An ink cartridgeis detachably connected to a head of a record apparatus and has a container main bodyhaving an ink tank chamberopened to the atmosphere in a state in which the head and the cartridge are connected and a first openingthrough which ink can be injected into the ink tank chamber (second ink storage chamber, etc.,). Such an intermediate wallpartitioning the ink tank chamberinto two space partsandplaced side by side in an ink injection direction is disposed in the ink tank chamberand is formed with a through partthrough which ink can be injected.

The present invention is a gas absorption device arranged in a liquid container storing a liquid fed to a liquid consumption apparatus. The device includes a decompressed container having an opening and a flexible film sealing the opening in the state that the decompressed container is internally decompressed. At least a part of a portion having an inner surface which receives the decompressed pressure in the decompressed container and an outer surface which is in contact with the liquid in the liquid container is formed by a gas permeable material through which gas dissolved in the liquid in the liquid container can permeate. According to the present invention, gas dissolved in the liquid stored in the liquid container can be absorbed using a decompressed space and the existence of a decompressed status necessary to absorb gas can be easily examined.

Disclosed is a resinous filter for an ink-jet recording apparatus, which is obtained by a process comprising: adding common salt to a melt of a resin comprising at least one member selected from the group consisting of polyethylenes having a number-average molecular weight of from 30,000 to 80,000 and polypropylenes having a number-average molecular weight of from 50,000 to 100,000; kneading the resultant mixture to prepare a melt to be molded; molding the melt to be molded to obtain a molding; and washing the molding with water to remove the salt therefrom.

An ink cartridge has a container main body [] having a through hole [] for making an ink storage chamber and an atmospheric open chamber [] to communicate with each other, and an atmospheric open valve [] having a valve body [] capable of opening and closing the through hole [] of the container main body [] and an elastic member [] capable of pressing the valve body [] in a closed direction. In an assembling structure of the atmospheric open valve [] in the atmospheric open chamber [], the valve body [] is placed at such a position blocking the opening of the through hole [], the elastic member [] is positioned in the atmospheric open chamber [] as a bend piece shaped like &#x3c; is expanded, and the elastic member [] in the positioned state presses at one end part the valve body [] in the closed direction and is fixed at an opposite end part to the inside of the atmospheric open chamber [
