Further, the lid handle 330 is formed of a plastic material resistant to heat.

The check valve 350 is movably mounted in the hollow core 330a and the upper portion of the check valve 350 protrudes above the upper end of the hollow cap 330b.

With the configuration of the lid handle 330, a single lid handle can simultaneously satisfy the vacuum function, the overflow prevention function, and the lifting function.

As shown in FIG. 6, the through-hole of the hollow core 330a serves as a passage for discharging water vapor or the like generated in the container 200.

At the lower end of the hollow core 330a, a latching flange 331a is formed which is hooked on the bottom surface of the lid body 310. [

The engaging flange 331a is caught by the lower surface of the through hole 311 when the upper end of the hollow core 330a is inserted into the through hole 311 from below.

A male screw 333a is formed on the outer peripheral surface of the hollow core portion 330a. Since this male thread 330a is formed between the engaging flange 331a and the upper end of the hollow core 330a, there is a certain height difference between the upper end of the hollow core 330a and the through hole 311.

The hollow cap portion 330b has a cylindrical or cylindrical shape penetrating up and down, and a female screw 333b fastened to the male screw 333a is formed on the inner peripheral surface.

The female screw 333b is also formed between the lower end of the hollow cap portion 330b and the upper end, particularly the lower end of the hollow cap portion 330b, between the discharge hole 320 described later.

Therefore, the height between the upper and lower ends of the hollow cap portion 330b is somewhat deep.

As shown in FIGS. 1 to 3, a discharge hole 320 is further formed at one side of the hollow cap portion 330b.

3, 6A and 6B, the discharge hole 320 is disposed above the upper end of the hollow core 330a so that when the water vapor exits the discharge hole 320, Do not disturb the top.

That is, as shown in FIG. 6B, when the water vapor is going to come out upward, the water vapor escapes to the discharge hole 320, thereby preventing condensation of water vapor due to a difference in height (depth) of the hollow cap part 330b, It is possible to prevent the water from flooding.

The discharge hole 320 is formed to pass through a rectangle having a long length from the top and the bottom to the left and right.

Further, it is preferable that the discharge hole 320 is disposed at a position facing the arm 330c.

The arm 330c protrudes in a radial direction of the lid body 310 from one side of the hollow cap part 330b when viewed from a plane and is inclined upward toward the rim from the center side of the lid body 310 when viewed from the side .

Therefore, the end of the arm 330c and the rim of the lid body 310 can stably erect the lid 300 that can be vacuumed.

Meanwhile, as shown in FIGS. 6A and 6B, the hollow cap part 330b is provided with a guide piece 340 for guiding upward the steam.

Particularly, the guide piece 340 is disposed at a position where the hollow cap 330b and the arm 330c meet, and serves as a detour for bypassing upward the water vapor directly toward the arm 330c.

In order to function as a detour, a guide piece 340 is provided on a part of the upper surface of the hollow cap part 330b as if it surrounds the wall.

The check valve 350 is made of a silicone material which is elastically deformable and harmless to the human body and has an opening and closing flange 351 placed on the upper face 337a of the opening and closing hole 335a formed in the hollow core portion 330a as shown in Figs. 6A and 6B, A hollow flange 355 attached to the lower surface 338a of the opening and closing hole 335a and a hollow flange 355 formed in the upper portion of the opening and closing flange 351, And a flange 359 formed between the stem 353 and the opening and closing flange 351. The flange 359 is formed of a metal plate.

The connection portion 357 is implemented as a plurality of connection strips 357 provided at predetermined intervals to form the discharge space S along the periphery of the hollow flange 355.

The shape of the stopper 353 may be hand-held.

The opening and closing flange 351 is of a flange type protruding outward from the lower side of the stem portion 353 so as to have a larger diameter than the diameter of the opening and closing hole 335a.

The hollow flange 355 has a disk shape and a through hole 356 is formed at the center thereof.

With this configuration, the check valve 350 forms a flow path through which the pressure inside the cooking chamber 200a is discharged to the outside through the through hole 336 and the discharge space S of the hollow flange 335c, The flow path is a one-way valve that blocks.

On the other hand, the diameter of the flange 359 is larger than that of the opening / closing flange 351 to function as an umbrella again and to be smaller than the diameter of the through-hole of the hollow cap portion 330b so that water vapor or the like is released into the edge gap c desirable.

In other words, the flange 359 functions as an umbrella for minimizing overflow when the foreign object overflows through the opening / closing flange 351.

On the other hand, as shown in Figs. 6A and 6B, it is preferable that a plurality of holes 359a are formed in the flange 359. Fig.

Since the clearance (c) is very narrow, water vapor that is discharged becomes a bottleneck and drips with time. When water droplets are formed, when the water vapor is continuously discharged, the water droplets are fried outward due to the pressure, resulting in dirty or burning.

Therefore, the hole 359a serves as an exhaust passage for water vapor as shown in FIG. 6B, thereby relieving the discharge bottleneck of water vapor and preventing water droplets from forming in the clearance c.

The packing 370 is an integral ring of a closed loop and includes a rim packing 371 that is largely fitted to the rim 312 of the lid body 310 as shown in Figs. 3, 3A, and 4, And a vacuum packing 373 placed on the upper end 231 of the vacuum chamber 200.
