<P>PROBLEM TO BE SOLVED: To provide a liquid storage vessel having a simple structure, which enables a low-viscousity liquid in a vessel main body to be discharged easily only in a required amount and which can be applied even to a small vessel. <P>SOLUTION: The liquid storage vessel comprises: the liquid storage vessel main body 1 which is deformable when pressed, elastically returns to its original shape, and stores a low-viscousity liquid; a cylindrical fitted part 2a which is fitted into the cylindrical opening 1a of the vessel main body 1; a flange 2b which abuts on the leading end of the cylindrical opening 1a; a nozzle body 2 including a nozzle portion 2c smaller than the inside diameter of the cylindrical fitted part 2a; and an inner cap 3 which is fitted so that a specific space A is left between the flange 2b of the nozzle body 2 and the inner cap 3. A narrow groove 5 is defined between the external face of the fitted part 3a of the inner cap 3 and the internal face of the cylindrical fitted part 2a of the nozzle body 2 so that the low-viscousity liquid flowing from a liquid inlet 4 is guided to the specific space A. Thereby high resistance is applied to the low-viscousity liquid, and the liquid is discharged only in the required amount. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
