Abstract
An ink cartridge and a method of disassembling the ink cartridge are provided. A casing body has a bottom formed with an ink delivery port extending therethrough. A casing lid joined to the casing body is formed with an air inlet port extending therethrough. The casing body and the casing lid forms a cartridge casing. The cartridge casing is filled with an ink-absorbent material. A delivery port-sealing film seals the ink delivery port. An air inlet port-sealing film seals the air inlet port. A filter is arranged within the casing body at a location inward of the ink delivery port by being inserted thereto from an ink-absorbent material side such that the filter is located between the ink delivery port and the ink-absorbent material. The casing body, the casing lid, the delivery port-sealing film, and the air inlet port-sealing film are formed of a resin material of the same kind. A gap is provided between an underside of the casing lid and a top surface of the ink-absorbent material, for allowing the cartridge casing to be cut thereacross. The ink cartridge is disassembled by the following steps: The ink cartridge is held in a vertically upside-down position. The ink cartridge is cut horizontally across the gap. Then, the filter and the ink-absorbent material are extruded by inserting a pusher from the ink delivery port.
