Ink cartridge having an atmosphere communicating channel of labyrinthine structure |
摘要 |
An ink cartridge for use in an ink jet printer includes a cartridge body and a lid. The cartridge body has an ink reservoir storing ink therein, arid is in a box-shape having one open surface. The lid is fixedly secured to the open surface of the cartridge body to hermetically seal the opern surface. The cartridge body is provided with a secondary housing formed with a hole open to atmosphere. In the secondary housing, inner walls are formed which define a communication channel of a labyrinthine structure for making a fluid communication between the ink reservoir and an outside atmosphere through the hole. The provision of such a communication channel smoothens the supply of ink to a print head but the labyrinthine structure prevents the ink evaporation.
