Abstract: An ink filling apparatus is constituted by an access unit (61) for reading an amount of ink consumed in an ink cartridge (10) which needs to be refilled from a storage unit (15) provided on the relevant cartridge and a filling controlling unit (60) for determining an amount of ink on the basis of the data. Ink in an amount corresponding to the amount of ink consumption stored in the storage unit of the ink cartridge (10) is filled by a filling apparatus (66).

Abstract: An ink cartridge for an ink jet printer having a housing having at least one wall. The ink cartridge further has at least two ink chambers for containing different ink accommodated in the housing. Ink supply ports are formed in one wall of the housing within each of the ink chambers. Each of the ink supply ports has an inner opening and an outer opening. The distance from the inner opening of a first ink supply port to that of a second ink supply port adjacent to the first ink supply port is different from a second distance from the outer opening of the first ink supply opening to that of the second ink supply port.

Abstract: An ink cartridge storage structure and method provide consistent print density and quality by mixing the ink when the cartridge is removed from the packaging and installed to a printer for use. An ink-filled ink cartridge with an ink supply port installable to the head of a printer is stored inside an individual box made to hold the ink cartridge. The ink cartridge is stored inside the individual box so that the ink supply port is at the top when the box is in the normal upright position.

Abstract: An ink supply port is sealed with a seal material made up of two layers of at least a physical protective layer and an airtight hold layer and formed with slits in the physical protective layer. When ink cartridge is mounted, a tip of an ink introduction member breaks the seal material sealing the ink supply port along the slits made in the seal member, and air is released to the atmosphere without raising pressure of a space of packing. Then, the ink introduction member penetrates the packing.

Abstract: Ink is filled in an ink cartridge having a housing communicating with ambient air through an air communicating hole, a porous member impregnating with ink, an ink supply port, and a valve device including a valve body always urged by a spring and a valve seat abutting against the valve body, and ink is filled in the housing of the ink cartridge through the ink supply port.

Abstract: 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.

Abstract: An ink cartridge has a container main body 2 having a through hole 60 for making an ink storage chamber and an atmospheric open chamber 501 to communicate with each other, and an atmospheric open valve 601 having a valve body 65 capable of opening and closing the through hole 60 of the container main body 2 and an elastic member 62 capable of pressing the valve body 65 in a closed direction. In an assembling structure of the atmospheric open valve 601 in the atmospheric open chamber 501, the valve body 65 is placed at such a position blocking the opening of the through hole 60, the elastic member 62 is positioned in the atmospheric open chamber 501 as a bend piece shaped like<is expanded, and the elastic member 62 in the positioned state presses at one end part the valve body 65 in the closed direction and is fixed at an opposite end part to the inside of the atmospheric open chamber 501.

Abstract: An ink cartridge 1 is detachably connected to a head of a record apparatus and has a vessel main body 2 having an ink tank chamber 11 opened to the atmosphere in a state in which the head and the cartridge are connected and an ink end chamber (second ink storage chamber 16, etc.,) communicating with the ink tank chamber 11 and leading to the head. The vessel main body 2 is formed with a first opening 85 communicating with the ink tank chamber 11 and a second opening 86 communicating with the ink end chamber.

Abstract: An ink cartridge 1 is detachably connected to a head of a record apparatus and has a container main body 2 having an ink tank chamber 11 opened to the atmosphere in a state in which the head and the cartridge are connected and a first opening 85 through which ink can be injected into the ink tank chamber (second ink storage chamber 16, etc.,). Such an intermediate wall 301 partitioning the ink tank chamber 11 into two space parts 11a and 11b placed side by side in an ink injection direction is disposed in the ink tank chamber 11 and is formed with a through part 301a through which ink can be injected.

Abstract: An ink tank cartridge for an ink-jet type recording apparatus is provided. The ink tank cartridge comprises a first chamber and a second chamber formed adjacent the first chamber. A porous member is housed in the second chamber. A partition wall separates the first chamber from second chamber, which communicate through a communication hole therethrough which extends along a portion of the width of the partition wall. An ink supply port extends through a wall of the first chamber and supplies ink to the exterior of the cartridge from the porous member. An air vent is spaced from the ink supply port provides ambient air to the second chamber. The pressure in the first chamber and the second chamber is at a value less than normal atmospheric pressure, and a pressure difference which retains the ink in the first chamber is also maintained between the first and second chambers by the surface tension of the porous member in the vicinity of the communicating hole.
