PURPOSE:To make possible the ink to be used without uselessness and the number of times of the exchange thereof to be reduced and a production thereof to be made easy, by making an elastic plate member as an integral configuration with the former is secured on the upper outside wall of the ink receiving bag storing the ink being sealed in the inside thereof constituted by a flexible membrane. CONSTITUTION:The upper side of a projection 13A is pressed down by a flat section 19B of an elastic plate member 19 through a flexible membrane 12A on the upper side of an ink receiving bag when a remaining amount of the ink in the ink receiving bag is reduced. But, the greater part of the remaining ink in the ink receiving bag 12A is flowed in the ink reservoir disposed inside of a connecting member 13 through a groove section 13B and can be used until the end thereof effectively, since the groove 13B is provided on the upper side of the connection member 13. Thereby, a defect such that there was much amount of remaining ink in a ink vessel can be removed, and the cheap ink having little trouble can be obtained. |
