PROBLEM TO BE SOLVED: To provide a pipette type pump dispenser which can suppress scattering of water drops and appearance of liquid dropping from a nozzle vent immediately after jetting and can attain stable jetting. SOLUTION: The pipette type pump dispenser 100 is provided with a pipette part 10, a nozzle part 20 which is joined to its upper part and a trigger 3 which elastically deforms the pipette part 10. The pipette part 10 repeats elastic deformation based on rotation of the trigger 3 and the pipette part 10 sucks liquid accommodated in a predetermined vessel and the liquid is ejected from the nozzle part 20. The pipette part 10 has a dome 1 which can be elastically deformed, a dome case 2 to which a lower end of the dome 1 is fitted and which has a liquid flow passage part S about at its center and a valve 4 which is fitted to the dome case 2 and which can open and close the flow passage part S. The trigger 3 pushes up the dome case 2, thereby the dome 1 is elastically deformed in a contraction direction to open the flow passage part S. COPYRIGHT: (C)2008,JPO&INPIT
