As shown in FIG. 2, the beak portion 31 has a crescent-shaped open bottom surface. A notch 32 opened downward is provided in a part of the peripheral wall 29 surrounded by the beak portion 31, and a storage space 33 for the safety valve 25 is provided inside the notch 32. The outer end of the above-mentioned connecting portion 23 projects from the inner wall of the storage space 33.

Two ribs 30 that correspond to the upper surface of the safety valve 25 are provided on the top surface of the storage space 33, and a partial groove 34 that extends to the front end of the beak portion 31 is provided between the two ribs 30. The outlet 35 portion of the safety valve 25 and a part of the discharge pipe 24 are fitted into the partial groove 34 (see FIG. 1).

A closing plate 36 that partially closes the crescent-shaped open portion of the lower surface of the beak portion 31 is detachably attached. However, the closing plate 36 may be omitted.

The safety valve 25 constituting the safety valve device 26 is composed of a case 37 and a valve body 38 housed in the case 37. An inlet 39 is provided on the inner side surface of the case 37 and the outlet 35 is provided on the upper surface. It is provided. The valve body 38 faces below the outlet 35 and closes the outlet 35 when the pot falls.

The discharge pipe 24 is connected to the outlet 35. The discharge port 41 at the tip of the discharge pipe 24 faces the strainer 42 provided on the closing plate 36.

With the upper edge 43 of the body member 27 fitted in the peripheral wall 29 of the shoulder member 22, the lower end open portion of the notch 32 portion of the peripheral wall 29 is partitioned by the upper edge 43 of the body member 27. The mounting port 44 as shown in FIG. 3 is configured.

The notch 32 need not be provided only in the shoulder member 22, and may be continuously provided at the upper end of the body member 27 or may be provided only in the body member 27.

The safety valve device 26 is inserted from the open portion of the lower surface of the beak portion 31 as shown by the arrow in FIG. 3, and the portion of the safety valve 25 is inserted into the storage space 33 from the mounting port 44. , Its inlet 39 is inserted into the outer end of the connecting portion 23. In this state, the lower surface of the case 37 rests on the upper edge 43 of the body member 27 at the mounting opening 44 portion (see FIG. 1), and the upper surface of the case 37 contacts the rib 30 for positioning.

When mounting the safety valve device 26, the safety valve 25 may be mounted first, and then the discharge pipe 24 may be inserted into the outlet 35 of the safety valve 25. By doing so, the safety valve 25 and the discharge pipe 24 can be individually downsized, so that the safety valve device 26 that is a combination of both can be made more compact.

The air pot of the first embodiment is as described above. When the hook lever 46 of the lid 45 is put on the fingertip to open the lid 45, the lid 45 is opened together with the inner plug 47. When the lid 45 is closed and the push button 48 is operated, the bellows pump 49 is compressed and the inside of the inner container 51 is pressurized. As a result, the content liquid is pushed up into the pumping pipe 20, and is discharged through the connecting portion 23 and the safety valve device 26.

When it is necessary to remove the safety valve device 26 for maintenance, the closing plate 36 is removed. Then, since the lower surface of the beak portion 31 is opened, the fingertip is inserted from the opened portion to grasp the discharge vipe 24, and when this is pulled outward, the entire safety valve device 26 can be taken out from the attachment port 44.
