In some cases, the inner lid 7 may not be placed in the specified position on the liquid supply port 21 because the inner lid 7 is shifted or tilted.
A problem arises in that airtightness is not maintained between the liquid supply port opening edge 21a and between the intermediate member vent and the pump discharge port.

In addition, in the pump injection type pot shown in FIG. 1, the liquid W in the liquid container 5 is heated to about 95°C by the water heater 18, and after boiling, the water is switched to the heat retention heater 19 to keep it at a constant temperature. It is now possible to do so.

Also, in this pot, when the pump operation plate 36 is pressed,
Pressurized air from the air pump 10 is blown into the liquid container 5, and the pressurized air causes the liquid W in the liquid container 5 to pass through a series of liquid passages 9 and be poured out from the spout pipe 12a. It has become.

Next, to explain the effects of the present invention, the pump injection pot of the present invention has the following effects.

(1) Since the liquid supply port 21 for supplying liquid into the liquid container 5 is formed with a wide mouth, the liquid pouring operation and the cleaning operation inside the liquid container 5 are facilitated.

(2) The inner lid 7 is attached to the inner surface of the substantially annular side peripheral wall 24 formed above the wide-mouthed liquid supply port 21 and the opening edge 21 of the liquid supply port 21.
Guide rib 30.30 for guiding to a predetermined position on a
Since the inner cover 7 is formed in a predetermined position on the liquid supply opening edge 21a by simply fitting the inner cover 7 into the side peripheral wall 24 without strictly aligning the inner cover 7 when the inner cover is attached, This makes it possible to securely place the inner lid 7 and the liquid supply port opening edge 21a in an air-tight manner, and also to ensure that the discharge port 35 of the pump device 10
and the ventilation hole 28 on the inner lid 7 side can be automatically matched.
