Abstract
An ink tank cartridge for an ink-jet type recording apparatus being removably mounted onto an ink supply needle of a recording body is provided. The ink tank cartridge is provided with a first chamber for storing ink and a second chamber for storing a porous member having ink impregnated therein. The second chamber communicates with the first chamber through a passageway formed within the cartridge between the first and second chambers. An ink supply port extends through and projects from a wall of the second chamber. The ink supply port supplies inks to the ink-jet recording apparatus through said porous member. A funnel-shaped packing member is provided within the ink supply port. The packing member is formed with a hole therethrough having a wide end and a narrow end and is dimensioned to receive the ink supply needle and to resiliently abutt against an outer periphery of the ink supply needle. The packing member is formed for preventing the flow of ink through the ink supply port other than through the ink supply needle when the needle is positioned in the ink supply port. The wide end of the hole is disposed away from the porous member.
