The upper end opening 4a of the liquid container 4 is covered with an inner lid 25, and the inner lid 25 has a passage 27 which is a part of an air passage 26 which serves as an air vent and steam vent passage for preventing natural pressure increase. and said pouring passage 1
A passage unit 29 is provided which includes a passageway 28 which is a part of the passageway 28. The water passage 28 connects the pumping pipe 11 and the pouring pipe 12, which extend downward and forward from the passage unit 29, respectively. The spout pipe 12 and the elevator pipe 14 are connected via a connecting pipe 13.
In other words, the pouring passage 10 includes the pumping pipe 11 and the water passage 2.
8, a pouring pipe 12, a connecting pipe 13, and an elevator pipe 14.

Therefore, the opening at the lower end of the elevator pipe 14 is intended to serve as a spout 40 that serves as an outlet of the series of spout passages 10.

On the other hand, inside the lid 2, there is a tubular member 30 that communicates with the air passage 28 of the passage unit 29 when the lid is closed and constitutes an air passage 26 for discharging air and steam inside the liquid container 4 to the outside. It is provided.
The outlet 31 of the air passage 26 is opened at the rear of the upper surface of the lid 2 (ie, at the end opposite to the spout), and a cap 32 having a gas-liquid separation function is provided there. Reference numeral 33 indicates the tubular member 3
This is a seal gasket for airtightly connecting the inlet 30a of 0 and the ventilation path 28.
