An ink cartridge for supplying ink to a recording head includes a vacuum producing material accommodating portion for accommodating a vacuum producing material; an ink containing portion for containing ink, adjacent the material accommodating portion, with which the ink containing portion is in fluid communication through an opening at a bottom portion; an ink supply opening for permitting supply of the ink, in the material accommodating portion; an inward projection in the ink containing portion; and the projection is not less than 0.2 mm away from a boundary between the material accommodating portion and the ink containing portion.
摘要:
An ink cartridge is described which is connectable to an ink jet recording head of an ink jet recording apparatus. The cartridge is generally formed by a front wall, a back wall, a top wall, a bottom wall and two side walls providing major inner surfaces of the cartridge. The cartridge includes a first chamber and a second chamber. The first chamber contains negative pressure producing material and has an ink outlet connectable to the ink jet head to supply ink from the cartridge to the ink jet head and an air vent for allowing air into the cartridge. The second chamber has a communication port adjacent to the bottom wall, and communicates with the first chamber through the communication port. The second chamber provides an ink reservoir for the first chamber. Inner corner portions, formed by intersection of the inner side of the side walls adjacent to the communication port and the bottom wall, and which extend toward the communication port, are rounded.

A package material for accommodating a container cartridge provided with an ink supply portion integral with a recording head in use includes a package material for accommodating the container cartridge, provided with opening means for permitting opening of the package material; a sealing material for sealing an ink supply portion of the container cartridge; wherein the sealing member is at least partly mounted to the package material.
摘要:
A liquid container for a liquid jet recording apparatus comprises a first chamber containing negative pressure producing material and having a liquid outlet connectable to a liquid jet head to supply liquid from the container to the liquid jet head and an air vent for allowing ambient air into the container, wherein the liquid outlet is provided in a bottom portion of the first chamber. A second chamber communicates with the first chamber by a communication path and is substantially hermetically sealed. A wall extends upwardly from the communication path of the first chamber. An ambient air introducing path is provided for between the wall and the negative pressure producing material extending from a point partly up the wall toward the communication path for introducing ambient air into the second chamber.
摘要:
An ink-tank cartridge has a first storage chamber housing a negative pressure generating member and having an atmosphere communicating portion communicated with the atmosphere, a second storage chamber in substantially enclosed condition and communicated with the first storage chamber only through a fine communicating portion located remote from said atmosphere communicating portion, and directly storing an ink to be supplied to the first storage chamber, the second storage chamber being arranged adjacent the first storage chamber; and an enclosed ink storage portion only communicated with the second storage chamber and located at respective side surfaces of the first and second storage chambers. The bottom surface of the enclosed ink storage portion is located at higher position than the bottom surface of the first and second storage chambers.
摘要:
A liquid discharging head includes a discharge port for discharging liquid, a liquid passage communicated with the discharge port, a bubble generating area for generating a bubble in the liquid in the liquid passage, the bubble generating area including a heater for heating the liquid in the liquid passage, and a movable member disposed in a confronting relation to the bubble generating area in the liquid passage and adapted to be shifted by pressure caused by generating the bubble at the bubble generating area to direct the pressure toward the discharge port and to be returned to its initial position by negative pressure due to contraction of the bubble, and wherein resistance of the movable member against the liquid in the liquid passage when it is shifted is smaller than that when it is returned.
摘要:
An ink filling method for filling an ink cartridge with ink to be supplied to a recording head for ejecting ink includes providing an ink cartridge having a negative pressure producing material accommodating portion and an ink accommodating portion, the negative pressure producing material accommodating portion accommodating a negative pressure producing material and being provided with an air vent, and the ink accommodating portion being substantially hermetically sealed except for fluid communication with the negative pressure producing material accommodating portion, and accommodating directly the ink to be supplied to the recording head, the ink cartridge further includes a partition wall between the negative pressure producing material accommodating portion and the ink accommodating portion, the partition wall being provided with a gap for permitting formation of meniscus of the ink; and directly injecting the ink into the ink accommodating portion.
摘要:
An ink cartridge includes a negative pressure producing material; an accommodating portion for accommodating the negative pressure producing material, the accommodating portion is provided with an opening for receiving an ink supply tube of an ink jet recording head; wherein the material is sandwiched between surfaces in the accommodating portion, and a distance between the surfaces smaller than twice an outer diameter of the ink supply tube.
