PROBLEM TO BE SOLVED: To solve the problem that variation is caused in the pressure applied to the ink contained in ink chambers of a plurality of ink packs overlapped in one case, due to the pressure acted on one ink pack from another adjacent ink pack which is in contact with the other one. SOLUTION: A multi-color ink cartridge 1 has first surface side liquid containing chambers 5(1) and 5(2) formed in the first surface side of a horizontal plate portion 31 of a rigid plastic plate 3, and second surface side liquid containing chambers 6(1) and 6(2) formed in the second side of it. The liquid containing chambers are arranged so as to be overlapped with one another in a zigzag manner in the width direction. The liquid containing chambers are formed by jointing front surface side concaved portions 51 and 52 formed in the horizontal plate portion 31 of the first surface and second surface side concaved portions 61 and 62 formed in the second surface with flat portions 53b to 64b of spatially formed flexible plastic films 53, 54, 63, and 64, respectively. Accordingly, its size in the liquid containing chamber arranging direction can be reduced, and liquid containing chamber exhibiting a high sealability can be formed. COPYRIGHT: (C)2005,JPO&NCIPI |
