It is possible to simplify the lid structure and reduce the heat-resistant portion only by manufacturing the lid.

Moreover, the steam discharging passage on the cover side discharges the steam from the peripheral part of the cover away from the push plate of the bellows pump to ensure the safety in use during the pressing operation of the push plate. Since the body side vapor vent passage can be formed by effectively utilizing the internal space of the lid, it is not necessary to provide a special space for forming the lid body vapor vent passage.

Further, the operating rod interlocked with the pressing operation of the push plate of the bellows pump closes the air supply port of the bellows pump which communicates with the air supply passage when the pressing plate is not pressed, and when the pressing plate is operated. Since the steam vent passage leading to the outside air is closed at the lower position linked to the pressing operation of the, the invasion of steam from the air supply passage into the bellows pump is prevented, and the heat resistance of the bellows pump is improved. The compressed air supplied into the liquid container is prevented from escaping to the outside air through the steam vent passage by using the pressing operation of the bellows pump, so that the smooth operation of the content liquid linked with the pressing operation of the push plate can be achieved. Can be dispensed.
