摘要

PROBLEM TO BE SOLVED: To provide an ink cartridge that can contribute to the conservation of resources by making the assembly and the disassembling recycling easy.;SOLUTION: An ink pack 24 which encloses ink is stored in a lower case 41, an upper case 51 is superimposed from above, and for example, the oscillating welding is performed between them. Thereby, the outer hull of the ink cartridge can be formed in an airtight state by the lower case 41 and the upper case 51. This configuration can be suitably used for a recorder designed so that air pressure may act on the ink cartridge to supply ink to a recording head side by the air pressure.;COPYRIGHT: (C)2007,JPO&INPIT
