  • Publication number: 20170341402
    Abstract: It is difficult to reduce the number of parts of a known bottle set. A bottle set includes: a bottle having an ink container capable of containing ink, and a nozzle through which the ink in the ink container can flow out; and a lid member that is attachable to and detachable from the bottle, and can cover the nozzle in a state where the lid member is attached to the bottle. An outflow port from which the ink in the ink container can flow out is formed in the nozzle, the lid member has a sealing portion that seals the outflow port in a state where the lid member is attached to the bottle, and the sealing portion is integrally formed in the lid member.

  • Publication number: 20160159099
    Abstract: A liquid jet apparatus comprises a liquid jet head, a carriage carrying the liquid jet head in a side-to-side direction, a liquid flow channel, and a liquid container in fluid communication with the liquid jet head through the liquid flow channel. The liquid container includes a liquid containing chamber arranged along a front/back direction orthogonal to the side-to-side direction; a liquid outlet port, from which the liquid contained in the liquid containing chamber flows to the liquid flow channel; and a liquid inlet port, through which the liquid is injected into the liquid containing chamber. The liquid inlet port has an end surface that does not face in a vertical direction relative to a normal posture of the apparatus.

  • Patent number: 9290001
    Abstract: A liquid container includes an ink chamber containing an ink to be supplied via a tube to a liquid ejecting head consuming the ink; an outlet port from which the ink contained in the ink chamber flows to the tube side; an injection port through which the ink can be injected into the ink chamber; and an air intake port taking air into the ink chamber from a further vertically upper position than a liquid level of the ink when the ink is contained in the ink chamber. If the ink equal to 5% of containing capacity containable in the ink chamber flows from the outlet port, the liquid container has an area where a fluctuation range of the liquid level of the ink inside the ink chamber becomes 5% or less of the cubic root of the containing capacity.

  • Patent number: 8398215
    Abstract: An intermediate liquid chamber is formed between an ink conducting path to which ink is supplied from an ink supply source such as an ink cartridge and a common liquid chamber to which ink to be provided to a plurality of pressure chambers is supplied. The intermediate liquid chamber communicates with both the ink conducting path and the common liquid chamber. The intermediate liquid chamber includes a conducting opening which communicates with the ink conducting path and a discharge opening which is opened to the common liquid chamber. The discharge opening is formed from one edge portion to the other edge portion of the common liquid chamber along a pressure chamber arrangement direction.

  • Patent number: 7762794
    Abstract: The tube 110 has a hollow portion 111 and a wall portion 112. The tube 110 has mutually contacting wall portions 111a that become compressed in such a way that the wall portion 112 comes into mutual contact in the hollow portion 111 through compression by a compressing mechanism 120, and is designed so that the mutually contacting wall portions 111a come into mutual contact, and the mutually contacting wall portions 111a recover upon release of the compressing mechanism. The mutually contacting wall portions 111a have readily contacting portions C1 that come into mutual contact at a certain level of compressing force, and contact resistant portions S1 that come into mutual contact only at a higher level of compressing force than in the readily contacting portions C1. The thickness of the wall portion 12 around the hollow portion 11 varies so that the readily contacting portions C1 are subjected to greater force than the contact resistant portions S1.
