  • the trigger type pump dispenser has an operating lever on the front side that corresponds to the trigger.When you hold it with your hand and move it to the front, the piston moves in conjunction with this, and the hydraulic pressure in the cylinder is reduced. Rise. As a result, the liquid is ejected vigorously from the nozzle.
  • the trigger type pump dispenser since the nozzle and the piston are integrated, when the trigger is gripped, the nozzle also moves downward together with the movement of the piston. Therefore, the trigger type pump dispenser has a problem that the liquid cannot be accurately discharged to a target location.

It is another object of the present invention to provide a pump dispenser in which the position of the nozzle does not move up and down when the liquid is discharged and can be easily handled by a person with a small hand.
  • the inventors of the present invention have intensively studied to solve the above-mentioned problem.When the trigger is moved up and down the piston part, the trigger is not directly attached to the piston part, but the above-mentioned problem is solved.

  • the body is composed of a flexible long nozzle part and a piston part. By pulling down the lever part and bringing it close to the handle part, the piston part is pulled down via the crank part and pressure is applied to the cylinder part. It exists in the pump dispenser which discharges a liquid through a long nozzle part.

Moreover, since the long nozzle part 12 which can be bent absorbs the vertical movement of the piston part 11, the movement of the long nozzle part itself is small.
