According to the present invention, the lid C is provided with a relief plate 10 for covering the container V and a pressure valve 20 which can be opened and closed as shown in Figs. 4A to 5C while pressing the relief plate 10 downward And a loop type hinge line 30 that convexly restores and convexly restores when the convex hull 10 is lifted upward.

FIG. 6 is a photograph of a decomposition of a vacuum pot according to the present invention, FIG. 7 is a photograph of a top of a vacuum pan according to the present invention taken from above, FIG. 8 is a photograph of a vacuum pan And the elevating member 24 is taken from the front.

When food is put into the container V and then boiled, an expansion pressure is generated to discharge the steam through the pressure valve 20. On the other hand, when the cooking is completed and the pressure valve 20 is closed while the heat energy is blocked, a contraction pressure is generated The vessel (V) is evacuated.

At this time, since the convex shape is maintained as it is in the case of the ordinary lid C, the vacuum state is maintained only in the state where the space between the container V and the lid C is not deformed, The effect of the vacuum storage of the food (the effect of storing the food for a long period of time so as not to decay) is limited.

4A to 4C, instead of allowing the steam to be discharged through the pressure valve 20 according to the expansion pressure generated when the food is put into the container V and then boiled, 5C, the convex plate 10 is pressed downward while closing the pressure valve 20 in a state where the cooking is completed and the heat energy is blocked, so that the convex hinge line 30 is recessed The space between the container (V) and the lid (C) is made smaller, and the vacuum state according to the relatively larger shrinking pressure is thoroughly maintained, thereby maximizing the effect of storing the food in a vacuum state .

At this time, the loop-type hinge line 30 is raised thinly and convexly from the bottom surface to the top surface, so that the convex plate 10 is elastically pressed or restored.

When the loop-shaped hinge line 30 is provided to the convex 10 of the lid C, the convex 10 is raised so as to have a relatively thin thickness while being convex so that the convex form of the convex 10, While the space between the container V and the lid C becomes smaller as the contraction pressure decreases and the convex plate 10 becomes concave while the concave plate 10 is intentionally pressed or the space between the container V and the lid C becomes concave, The convex structure 10 and the concave shape of the lid C can be more easily and easily changed by keeping the concave state smoothly while bending the convex plate 10 along the boundary of the hinge line 30.

Further, a packing wing (C1) protruding along the outer rim of the lid (C) and coming into close contact with the rim of the inner wall of the container (V) ensures the mutual sealing force.

4A to 8, the pressure valve 20 applied to the vacuum pan according to the present invention includes a center hole 21 pierced in the center of the convex plate 10, A cylindrical body 23 rising upward from the convex 10 on the outer side of the satellite hole 22 and having a vapor hole 23a in the horizontal direction, The ascending / descending member 24 which discharges the steam sprayed through the satellite hole 22 through the steam hole 23a and closes the satellite hole 22 to keep the container V in a vacuum state when descended, .

It is possible to simplify the discharge and sealing of the steam according to the ascending and descending of the ascending / descending member 24, and in particular, the ascending and descending member 24 is covered with the cylindrical member 23 so that it is apparently clean, Further, when the steam is exhausted in the horizontal direction toward the steam hole 23a of the cylindrical body 23 as the passage of the steam when the satellite hole 22 is opened and the cylindrical body 23 is utilized as a handle, So that the satellite hole 22 can be easily and tightly closed by the descent of the ascending / descending member 24, which is preferable.

At this time, when the ascending / descending member 24 is lifted while having the lower flange 24a and the upper protruding jaw 24b as the boundary of the center hole 21, the lower flange 24a is caught on the lower surface of the relief plate 10, The opening 22 is opened while the upper projection 24b is brought into close contact with the satellite hole 22 to realize the correct opening and closing operation as the pressure valve 20.

 Preferably, the looped hinge line 30 comprises an inner looped hinge line 31 and an outer looped hinge line 32 concentric with the relief 10.

When the loop-like hinge line 30 is uniquely given to the relief plate 10, a sudden bending phenomenon may occur when the relief plate 10 is deformed from a convex shape to a concave shape. In the convex plate 10, The inner loop type hinge line 31 and the outer loop type hinge line 31 are arranged at the timing when the convex hull 10 is deformed from the convex shape to the concave shape or vice versa as required when doubled by the hinge line 31 and the outer loop type hinge line 32. [ The outer loop type hinge line 32 can be smoothly bent while being interlocked with a kind of articulation motion, thereby further enhancing the convenience of use.

At this time, the lid C is made of silicone resin, and can be realized much more smoothly when the convex form 10 and the concave form of the convex plate 10 are deformed. Further, the container V is made of silicone resin, It is of course possible to further include a reinforcing piece V1 protruded along the side surface of the container V to prevent the container V from being deformed by heat when the container V is made of silicone resin.

The present invention can be used in a kitchen container (V) for cooking or boiling food or a kitchen container (V) industry for a microwave oven.
