Abstract: An ink cartridge for an ink jet printer is provided. The provided ink cartridge has an ink reservoir and a housing for covering the ink reservoir with a negative pressure maintenance unit therebetween, to maintain the inner pressure of the ink reservoir under a negative pressure. Since the negative pressure maintenance unit does not contact ink in the ink reservoir, the negative pressure maintenance unit does not corrode. In addition, the negative pressure maintenance unit is installed between the housing and the ink reservoir while occupying a small space, and thus improving the filling efficiency of ink in the ink reservoir.

Abstract translation: 提供了一种用于喷墨打印机的墨盒。 所提供的墨盒具有墨水容器和用于利用其间的负压维持单元覆盖墨水容器的壳体，以将墨水容器的内部压力保持在负压下。 由于负压保持单元不接触储墨器中的墨，所以负压维持单元不会被腐蚀。 另外，负压保持单元安装在壳体和墨水容器之间，同时占据很小的空间，因此提高了墨水容器中墨水的填充效率。
