A waste liquid container is detachably mounted on a mounting unit which includes a discharge portion discharging a waste liquid and a projection to which a substrate connection portion is joined. The waste liquid container includes: a containing portion that is able to contain the waste liquid; a connection concave portion that is opened in a mounting direction; a circuit substrate that includes connection terminals electrically connected to the substrate connection portion and is joined to the connection concave portion; and a waste liquid introduction portion that is connected to the discharge portion. In the connection concave portion, one pair of guide portions guiding the projection is formed so that the connection terminals are interposed therebetween in a width direction intersecting the mounting direction. Of the pair of guide portions, one guide portion is disposed between the connection terminals and the waste liquid introduction portion in the width direction.

A method for sealing an ink cartridge is disclosed. A cover film is bonded to the ink cartridge in such a manner as to cover an ink inlet hole formed in the ink cartridge. An opening is formed in the cover film in such a manner as to communicate with the hole of the ink cartridge. The method includes preparing a seal film and bonding the seal film to the cover film with a bonding strength smaller than the bonding strength of the cover film with respect to the ink cartridge in such a manner that the seal film becomes peelable from the cover film, thereby sealing the opening of the cover film.

A piercing method for forming an opening in a cover film welded to an ink cartridge in such a manner as to cover first and second ink inlet holes is provided. The method includes: forming a cut in the cover film in such a manner as to provide a cut piece supported in a cantilever manner in a covering area of the cover film that covers the first and second ink inlet hole; and forming the opening in the cover film by causing the cut piece to hang down in the first and second ink inlet holes.

A method for sealing an opening formed in a cover film welded to a fluid retainer at a position corresponding to a covered area of an ink inlet hole. A sealing member, which seals the opening, is a laminated film including a first film and a second film. The method includes preparing the laminated film, placing the laminated film on the fluid container with the first film facing the fluid container in such a manner that the laminated film covers the opening, and sealing the opening with the laminated film by heating the sealing member covering the opening from the side corresponding to the second film to melt the first film.

A method for sealing a bore formed in a cover film is disclosed. An ink inlet hole formed in an ink cartridge is covered at a hole covering area of the cover film. The method includes formation of a recess outside the hole covering area by removing a portion of the cover film, mounting a seal film on the cover film in such a manner that the seal film covers the bore, and sealing the bore with the seal film by heating the seal film with the seal film mounted on the cover film and thereby melting a side of the seal film opposed to the cover film.

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.

A method of refilling an ink bag that is used in an ink jet recorder, the ink bag is initially filled with ink through an opening in the bag, and is sealed after the ink bag is initially filled. The method comprises the steps of removing the ink bag from the ink jet recorder, positioning the ink bag, inserting an ink needle into a separate opening in the ink bag that is different than the first opening through which the ink bag is initially filled with ink, discharging ink from the ink bag through the second opening, and charging the ink bag through the second opening with a specified quantity of ink.

Ink cartridge for printer

A method of refilling an ink bag of an ink cartridge for use in an ink-jet recorder. The method includes first removing the ink cartridge and ink bag from the ink-jet recorder. The ink bag may then be refilled by positioning the ink bag on a surface, inserting an ink needle into a port of the ink bag, and by discharging ink from the ink bag and charging the ink bag with a specified quantity of ink.
