PURPOSE:To dispense with a cartridge container and end cap and to reduce the production cost by filling a water in the container with holding a fine line and feeding piece on the center axial part of the container and by freezing at least the outer layer part of said water. CONSTITUTION:A cartridge 26 is made a cylindrical ice 28 with the water as of a tube expansion medium being frozen. A fine line 14 is held on the nearly center axial part of the ice 28 and one end of the fine line 14 is connected to the feeding piece 16, the one part of which is entered into the end of one part of the ice 28 and the other end is extended outside from the end of the other part of the ice 28. The ice 28, therefore, serves as both a conventional cartridge container and end cap as well as the tube expansion medium. The cartridge container and end cap are thus dispensed with. |
