Abstract

An ink cartridge comprising an ink chamber, an air introduction opening which introduces air into the interior of the ink chamber, a first sealing member capable of blocking and allowing communication between the air introduction opening and the outer area of ​​the ink cartridge, an ink supply opening , which supplies ink from the ink chamber, a second seal capable of blocking and allowing communication between the ink supply opening and the outside area of ​​the ink cartridge, and a check valve, which is provided between the second seal and the ink chamber , wherein the check valve in the ink supply opening blocks the flow of ink from an area outside the ink supply opening to the ink chamber.

Description

technical field [0001] The present invention relates to an ink cartridge mountable to an inkjet recording apparatus. Background technique [0002] In Japanese Laid-Open Patent Application No. H9-85963, there is proposed an ink jet recording apparatus, which has a structure allowing attachment and detachment of an ink container (hereinafter referred to as an ink cartridge). An inkjet recording device includes two chambers that hold ink cartridges. A porous material is filled in each chamber, and projections projecting upward from the upper ends of the two chambers are formed. One chamber includes a porous material connected to the air introduction opening, and the lower surface of the porous material of the other chamber is connected to the ink supply opening. [0003] The ink cartridge is provided with a through hole at the bottom to allow insertion of each protrusion. By attaching the ink cartridge to the mounting portion, the two chambers and the inside of the ink cartr...
