PROBLEM TO BE SOLVED: To enable easily discharging liquid contents with little force by providing a moving cylinder communicating with a nozzle pipe and moving in an outer cylinder, connecting a vertically movable pressing body to the moving cylinder, and pushing the moving cylinder into an outer cylinder to discharge a fluidized liquid sucked up from the end part of the outer cylinder from the nozzle pipe. SOLUTION: In the case liquid contents are discharged from a discharge port 29 at the tip of a nozzle pipe 28, when a pressing body 32 is pushed down, a moving cylinder 18 is moved downward in an outer cylinder 14 while an elastic member 30 is contracted, And when downward movement of the moving cylinder 18 is stopped, if force application to the pressing body 32 is stopped, the moving cylinder 18 is pushed up by the elastic member 30. At this time, a pressure change part 14 becomes under negative pressure, and the liquid contents are sucked up through a dip tube 16 and are accumulated in the pressure change part 14. After that, when the pressing body 32 is pushed down again to descend the moving cylinder 18, the liquid contents accumulated in the pressure change part 44 are discharged from a discharge port 29 through an inner pipe 24 of the moving cylinder 18 and a flow passage in the nozzle pipe 28. |
