Document Type and Number:
WIPO Patent Application WO/2021/029365
Kind Code:
A1
Abstract:
[Problem] To provide a filling nozzle of a liquid filling device, which can discharge various liquids from a low-viscosity liquid to a high-viscosity liquid or a solid substance-containing liquid, does not generate liquid dripping or falling from the contained solid substance after the liquid is completely filled, and can suppress liquid splashing and foaming in a container. [Solution] This filling nozzle 3 comprises a substantially vertical cylindrical nozzle body 4, and a substantially vertical rod-shaped spool 5 that is inserted into the nozzle body 4 to be vertically slidable. A liquid inflow port 51 and a liquid discharge port 52 are formed on the outer peripheral surface of the spool 5, and a liquid circulation path 53 causing the liquid inflow port 51 and the liquid discharge port 52 to communicate with each other is formed inside the spool 5. A liquid introduction hole 41 is formed in a through shape in the nozzle body 4. When the spool 5 is being filled with the liquid, the liquid inflow port 51 communicates with the liquid introduction hole 41 of the nozzle body 4, and the liquid discharge port 52 is lowered to a position where the liquid discharge port 52 is exposed and opened to the lower side of the nozzle body 4, and when the spool 5 is completely filled with the liquid, the liquid discharge port 52 is raised to a position where the liquid discharge port 52 is blocked by the inner peripheral surface of the nozzle body 4.
