Abstract
A second sealing film Fis thermally bonded onto a leading end portion Rof an ink lead-out memberof an ink pack and an annular projecting portion Rprovided on an ink casing. Thereby, a gap D produced between the ink lead-out memberand the ink casingcan be closed from outside the ink casing. Accordingly, the airtightness of a space S in the ink casingis kept, thus making it possible to raise the pressure in the space S and generate such a force as to crush the ink pack.
