Description

[Detailed description of the invention] This invention relates to improving the lid of an air pot that is attached to the top of the pot body.The purpose of this invention is to create an air pot with a simple structure, fewer assembly parts, and to prevent misuse. To provide the lid body.

Embodiments of the present invention will be described below with reference to the drawings.

The lid A of the air pot of the present invention is attached to the upper ice cutter 2 of the pot body 1, and is attached via a lower plate 3 screwed to this drainer 2 and an annular packing 4 in the center of this lower plate. The bellows 5 and the spring 6 built into this bellows
, a push plate 7 that locks the uppermost end of the bellows, a suction valve body 8 attached to an air suction hole in the center of the push plate, and the lower plate 3.
It is composed of a frame 9 that is fitted into the outer periphery and surrounds the bellows and the outer periphery of the push plate, and a cover unit 18 that covers the upper surfaces of the push plate 7 and the suction valve body 8.

As shown in FIG. 2, the frame 9 is fitted onto the outer periphery of the lower plate 3, has an opening in the center at the top, and has a downwardly directed annular guide portion 10 on its peripheral wall.

As shown in FIGS. 2 and 3, at the rear of the upper part of the frame 9, a locking part 19 for attaching the cover assembly 18 is provided, and at the front of the upper part, a finger push-up part 20 for pushing up the cover assembly is provided. ing.

The push plate 7 has a sliding part 11 that slides up and down along the inner peripheral surface of the guide part 10, an annular part 12 that projects from the lower end of this sliding part to the side wall of the frame, and an annular part 12 that extends inwardly from the upper part of the sliding part. A mounting portion 13 extending toward the
4 are integrally molded, and an air suction hole is provided in the center of this mounting portion.

The uppermost surface of the push plate 7 is formed to be equal to or slightly protrude from the uppermost surface of the frame body 9.

The guide portion 10 of the frame body 9 is formed in such a length that it always comes into contact with the upper part of the sliding portion 11 of the push plate 7 which is lowered to its lowest position by pressing.

The suction valve body 8 is placed on a placing part 13 of a push plate,
As shown in Fig. 2, it is locked to the air suction hole in the center of the push plate.

The bellows 5 has a lower contact portion 15 that contacts the lower plate 3;
It consists of this upper bellows part 16 and an upper abutting part 17 above this bellows part, and the lower and upper abutting parts 15 and 17 are integrally molded to be thicker than the bellows part 16. The portion 17 is formed in a stepped manner so as to come into contact with the lower surface of the annular portion 12, the inner surface of the sliding portion 11, and the inner surface of the locking portion 14 of the push plate.

The upper abutting part of the bellows that comes into contact with the inner surface of this locking part 14 is a small diameter part, and the outside diameter of this small diameter part is equal to or slightly larger than the inner diameter of the press locking part 14, and this small diameter part is pressed. It is fitted onto the inner surface of the locking portion 14 of the plate.

The spring 6 built into the bellows 5 has its lower end in contact with the inner side of the lower contact portion of the bellows, and its upper end in contact with the lower side of the suction valve body 8, so that the above-mentioned suction valve body 8 and the push plate 7 are always kept upward. It is pushing up.

As shown in FIGS. 2 and 3, a cover unit 18 covering the upper surfaces of the push plate 7 and the suction valve body 8 is attached to the locking portion 19 of the frame via a pin 21 so as to be openable and closable. The surface is placed on the peripheral wall of the central opening of the frame.

As described above, in the present invention, a finger pushing part is provided in front of the central opening of the frame, a locking part integrated with the cover is provided in the rear,
Since the push plate that slides up and down within the center opening of the frame body and the cover that covers the top surface of the intake valve body are integrated, the structure is simple and has a small number of parts, and the cover can be removed by inserting your finger into the push-up part. It can be opened simply by pushing up on one piece, and the suction valve body can be pressed, making the operation extremely simple.

Furthermore, since the lower end circumferential surface of the cover unit is placed on the central opening circumferential wall of the frame body, even if the cover unit is pressed by mistake, the suction valve body will not be pressed down, so that the high temperature liquid in the pot body can be drained. It is highly safe as it does not eject.
