Abstract: A liquid container and an apparatus in which the liquid container is mountable are provided, the liquid container and the apparatus enabling the presence or absence of remaining liquid to be checked without the need for a power source and even after the liquid container is removed. The pressure in a communication path is maintained while ink in a containing section is not supplied to the exterior. Thus, the displacement state of a detection valve which is displaced depending on the pressure in the communication path can be maintained even after removal of an ink tank.

Abstract: The invention is to prevent positional deviation of a sealing valve, improve bubble releasability during atmosphere introduction, and stably supply ink to a recording head. The configuration is provided with an opening 270 on an upper portion of a cylindrical regulating body 165 of a joint base 140 in a state where an ink tank 100 is mounted on a connection unit 10 of a printer.

Abstract: A liquid container enables a liquid contained in a liquid containing chamber to be supplied to an exterior through a supply port. The liquid container includes a first channel, a second channel, and a communication path. The first channel is in communication with a first opening which opens into the liquid containing chamber. The second channel is in communication with a second opening which opens into the liquid containing chamber, the second opening being positioned above the first opening in a direction of gravitational force. The communication path allows the first channel and the second channel to communicate with each other outside the liquid containing chamber to permit a flow of the liquid.

Abstract: An ink tank for being installed in an ink jet recording apparatus to supply ink thereto, including an ink storage portion, one side surface of a casing of the ink tank in which side surface an opening for supplying ink to the apparatus is formed, and a joint member for joining the one side surface to the apparatus by engaging with a connection member of the apparatus. The joint member has a welding portion for being welded to the one side surface along a peripheral portion of the opening, the welding portion corresponding to the peripheral portion; and a hollow portion forming a positioning hole for inserting therein and engaging therewith the connection member for determining a relative position of the apparatus and the one side surface. The hollow portion is provided on the outside of the welding portion and abuts to the one side surface without being welded.

Abstract: A method of producing a liquid cartridge having an identification part corresponding to a type of liquid held inside the liquid cartridge, the method includes preparing the liquid cartridge having a plurality of protrusions protruding from an external wall; and forming the identification part corresponding to the type of liquid by melting at least one of the protrusions. In this way, a strong mis-loading prevention part that prevents mis-loading of the liquid cartridge into a liquid consuming apparatus can be constituted without generating waste.
