PURPOSE: To prevent bubbling of filling liquid by forming a sealing gap of a degree capable of stopping passage of liquid between the inner circumferential face of the body of a nozzle and the outer circumferential face of a disk and forming the lower liquid flow path in the inside of the upper liquid flow path in the middle of the center of the disk and the outer circumference.
CONSTITUTION: The upper liquid flow path 53 is covered with a packing 63 and closed by a check valve 12 in a state in which a disk 56 is closely touched to a sheet ring 51 through the packing 63. When liquid is sent to the body 11 of a nozzle, a valve 57 resists a spring 59 and is lowered by liquid pressure. The disk 56 is isolated from the sheet ring 51. Then the upper liquid flow path 53 is opened and liquid in the body 11 of the nozzle is passed through the flow path 53. While the liquid passed through the flow path 53 is collected toward the inside, it is passed through the lower liquid flow path 61 and guided to the tapered middle part 36 and the small-diameter lower part 37 of the lower member 22 of the body of the nozzle and discharged from the body 11 of the nozzle without being spread.
