PURPOSE: To provide a discharge mode changeover device of a pump dispenser which is capable of changing over discharge modes of all of rectilinear flow, vortex flow and bubbles and does not generate disturbance in each discharge flow. CONSTITUTION: This discharge mode changeover device has a valve mechanism having a first flow passage 15 for forming misty discharge liquid flow, a second flow passage 14 for forming rectilinear discharge flow and an operating member 11 for opening and closing the first and second flow passages 15, 14 and a movable adapter 13 for bubbling which bubbles the discharge liquid flow by interfering the misty discharge liquid flow discharged through the first flow passage 15. The changeover of the three modes, i.e., the first mode to discharge the liquid in a mist form, the second mode to discharge the liquid as rectilinear flow, and the third mode to stop the discharge of the liquid is made possible, and further, the changeover to the fourth mode which discharges the liquid in a bubble form by an adapter 13 for bubbling is made possible by the valve mechanism. |
