Title: Ink cartridge device of ink jet printer
Inventor: ISHIKAWA CHUJI
IPC: B41J2/175
Filed: 1986-12-26
Abstract: PURPOSE:To enable the variation in fluidity of ink and dilution liquid to be controlled to a low level with almost no change of the bending resistance of a tank even at a low temperature, by utilizing a polyester elastomer as the material of the tank. CONSTITUTION:The material of tanks 26a, 26b is elastomer of the polyester system. Therefor, its bending resistance is scarcely changed even at a low temperature and the variation in fluidity of ink 27a and dilution liquid 26 can be controlled to a low level. Further, because the bottom part 33a of a rubber stopper 33 extrudes conically to the inside of the tanks 26a, 26b, the internal pressure of the ink 27a in the tank 26a and of the dilution liquid 27b in the tank 26b always acts in the central direction. Further, because the central part of said bottom part 33a is thin in wall thickness, its action of internal pressure increase. Therefore, even through for example, cracks occur at the bottom part 33a, they can not immediately be closed. Further, even through hollow needles 35a, 35b are pulled out, no pulled out hole remains thereafter and said hole is instantly sealed.
