Abstract
An ink cartridge for an inkjet printer includes a housing, an output channel, a porous material, and an adhesive layer. The housing has a vertical ink chamber for storing ink and an opening disposed on a top side of the ink chamber for interchanging air inside the ink chamber with air outside the ink chamber. The output channel is connected with a bottom side of the ink chamber for supplying ink from the ink chamber. The porous material is filled in the ink chamber for absorbing ink within the ink chamber. The adhesive layer is formed on a top end of the porous material for forming a sealed surface on the top end of the porous material.
