PROBLEM TO BE SOLVED: To provide a liquid filling nozzle capable of preventing dripping of a high viscous content in filling a pouch with a plug.SOLUTION: A liquid filling nozzle comprises a pipe through which liquid flows, and a plunger provided inside the pipe for controlling a flow rate. The liquid filling nozzle has an air hole penetrating a central part of the plunger. A hole connected to the air hole for jetting air radially is provided at a lower tip of the plunger. A fluorine-based nanoparticle coating layer is provided on a surface of the lower tip of the plunger.SELECTED DRAWING: Figure 1 |
