<P>PROBLEM TO BE SOLVED: To provide a liquid quantitative discharge device which can feed a determined quantity of liquid such as water, even though the quantity is small, when feeding the liquid from a liquid holding container, and further can feed the liquid not influenced by whichever position the device may assume. <P>SOLUTION: This liquid quantitative discharge device comprises the liquid holding container 2 where the liquid is held, a liquid discharge channel for discharging the liquid from the liquid holding container 2, a gas holding container 1 for holding compressed gas, a gas feed channel for feeding the inner compressed gas of the gas holding container 1 into the liquid holding container 2, and an inflatable bag member 15 fitted to the end part, of the liquid holding container side, of the gas feed channel. The bag member 15 is inflated inside the liquid holding container 2 by feeding the compressed air into the bag member 15, and discharges the liquid equivalent to the expanded volume of the bag member 15 from the liquid discharge channel. <P>COPYRIGHT: (C)2008,JPO&INPIT |
