ABSTRACT:
A plunger for a syringe of a liquid dispenser comprises a tapered front end section12having at its rear end16an outer diameter slightly smaller than the inner diameter of the syringe, a cylindrical drum section14continued to the rear end16of the tapered front end section12, having a maximum outer diameter substantially the same as the inner diameter of the syringe and opening there, and a collar member24(30, 32) slidably formed by coupling with an outer circumferential surface in the vicinity of an opening22of the drum section14and maintaining the close contact with an inner wall surface26of the syringe18, thereby inclination toward the syringe is eliminated and action within the syringe is constantly made smooth.
