Description

Packing, lid for vacuum pot using this packing, and vacuum pot [0001]

The present invention relates to a vacuum in which a groove is formed in a close contact surface, a packing in which restoration is reliably performed in an adhered state when vacuum is released, a vacuum pot lid and a vacuum pot using the packing.

Conventional vacuum pot lid packings have been proposed in Patent Document 1 (Korean Utility Model Publication No. 20-0451215) and Patent Document 2 (Korean Patent Laid-Open No. 10-2013-0030345).

As shown in FIG. 6, the packing 10 for a cooking container of Patent Document 1 has a ring shape as a whole, and on the outer surface thereof, a cut portion 11 formed in accordance with the shape of the packing 10, And a plurality of projections 30 are annularly arranged on the upper surface of the second contact piece 22. The first and second contact pieces 22,

The protrusion 30 can be restored to its original state by minimizing the surface area of the two contact pieces 20 and 22 when the cut-out portion 11 contracts.

As shown in Fig. 7, the packing 10 of the frying pan cover of Patent Document 2 includes a ring-shaped body 11 having a glass inner portion 12 into which the glass of the lid is inserted, And a space retaining protrusion 15 for maintaining a space between the body 11 and the close plate 13 so as to prevent the lid from detaching from the upper flange .

Therefore, the gap holding protrusion 15 formed on the lower side of the body 11 presses the contact plate 13 to be in horizontal contact with the upper flange of the frying pan, and maintains the vacuum state inside the frying pan.

Also, in the process of repeating the process of opening and closing the lid as described above, the packing 10 is too tightly adhered to the lower side of the body 11 to prevent the packing plate 13 from being restored to its original state The gap maintaining protruding portion 15 formed on the body 11 has a function of pushing the close contact plate 13 and a function of pressing the body 11 and the close contact plate 13 So that the restoration of the fastening plate 13 is smoothly performed.

In Patent Documents 1 and 2, although protrusions are provided for restoration, the protrusions are pierced due to the characteristics of projected protrusions, so that they can be firmly adhered in a curved shape without constant contact. Particularly, When it occurs, more bending phenomenon may occur.

Due to such bending of the close contact, it is not possible to make a flat contact, and the degree of vacuum inside the container is low, so that the function as a vacuum pot can be weakened.

In the vacuum pot lid packing according to the second aspect of the present invention, the groove may be composed of a first groove formed on the upper surface of the vane packing and a second groove formed on the lower surface of the lower flange, And the second grooves are arranged in a zigzag form.

In the vacuum pot lid packing according to claim 3 of the present invention, the first groove and the second groove are arranged in a zigzag shape so that a part thereof overlaps.

In the vacuum pan lid packing according to claim 4 of the present invention, the bottom surface of the lower flange has a downwardly convex round surface.

According to a fifth aspect of the present invention, there is provided a vacuum pan lid comprising: a lid body for opening and closing a container; A check valve installed in the lid body; A packing fitted to an edge of the lid body; And a support member for supporting the packing on a rim of the lid body, the rim packing comprising: a rim packing fitted to a rim of the lid body; a wing packing extending obliquely from a lower surface of the rim packing, And a lower packing extending downward from a lower surface of the rim packing and disposed on an upper inner side of the container, wherein the rim packing comprises an upper flange and a lower flange disposed on an upper surface and a lower surface of the rim of the lid body, And a web connecting one end of the flange. Grooves are formed on the bottom surface of the lower flange or on the upper surface of the vane packing at predetermined intervals along the circumference.

A vacuum pan according to a sixth aspect of the present invention includes a container having a bottom and a side wall, and a vacuum pan lid for opening and closing the inside of the container and for evacuating the inside of the container, wherein the lid body for the vacuum pan; A check valve installed in the lid body; A packing fitted to an edge of the lid body; And a support member for supporting the packing on an edge of the lid body, wherein the lid body comprises: a frame packing fitted to a rim of the lid body; a wing packing extending obliquely from a lower surface of the rim packing, And a lower packing extending downward from a lower surface of the rim packing and disposed on an upper inner side of the container, wherein the rim packing comprises an upper flange and a lower flange disposed on an upper surface and a lower surface of the rim of the lid body, And a web connecting one end of the flange. Grooves are formed on the bottom surface of the lower flange or on the upper surface of the vane packing at predetermined intervals along the circumference.

The present invention has the following effects.

Since the grooves are formed on the bottom surface of the lower flange or the upper surface of the vane packing at predetermined intervals along the circumference, the flatness of the grooves can be made constant so that the degree of vacuum inside the container can be increased, Is very good.

Further, by arranging the first groove and the second groove staggeredly, it is possible to further reduce the close contact area and to further increase the restoring force while maintaining a constant close contact.

Particularly, by arranging the first groove and the second groove so as to overlap each other in a zigzag manner, the contact surface of the second groove is placed on the first groove (or the contact surface of the first groove is placed on the second groove) .

In addition, since the bottom surface of the lower flange is formed of a rounded surface with a downward convexity, when the flattened surface is formed, when the vacuum is released, the convex round surface is restored and the first groove is pushed out so that the vane packing is adsorbed on the lower flange .

Particularly, since the convex round surface is shrunk and expanded against the lid body made of rigid reinforced glass as compared with the packing made of silicon, the lid body is more rigid than the cantilevered wing packing, Return.

1 and 2, a vacuum pan 100 according to the present invention includes a container 200 having a cooking chamber 200a, a vacuum lid 300 for opening and closing the cooking chamber 200a of the container 200, ).

2 and 3, the container 200 includes a bottom 210 and a side wall 230 protruding upward from an edge of the bottom 210 to form a cooking chamber 200a therein.

As shown in FIGS. 1 to 4, the vacuumable lid 300 includes a lid body 310 at least partially transparent or semitransparent to check the inside of the container 200, and a check valve A packing 370 fitted to the rim of the lid body 310 and a support member 390 for supporting the packing 370 to the rim of the lid body 370. [

The lid body 310 may be embodied as whole transparent glass or partially transparent or translucent reinforced plastic, but tempered glass is preferred.

Particularly, the check valve 350 is disposed inside the lid handle 330 provided at the through hole 311 formed at the center of the lid body 310. [

Of course, the check valve 350 may be provided on the lid body 310 separately from the lid handle 330. [

The function of the check valve 350 is described in Korean Patent Publication No. 10-1426852, and a detailed description thereof will be omitted.

The lid handle 330 includes a hollow core 330a inserted and inserted from below the through hole 311, a hollow cap 330b coupled to the lid body 310 by being coupled to the hollow core 330a protruded upward, And an arm 330c protruding in the radial direction of the lid body 310 from one side of the hollow cap portion 330b.

Further, the entire lid handle 330 may be formed of a plastic material resistant to heat, or only the hollow core 330a may be formed of a metal such as stainless steel.

As shown in FIGS. 1 and 2, a discharge hole 320 is further formed at one side of the hollow cap portion 330b.

This discharge hole 320 prevents the water vapor from condensing due to the difference in height (depth) of the hollow cap part 330b by allowing the water vapor to escape to the discharge hole 320 when the water vapor is going to come out upward, 330b. ≪ / RTI >

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

Also, it is preferable that the discharge hole 320 is disposed at a position facing the arm 330c as shown in Figs.

The packing 370 is an integral ring of a closed loop and is composed of a rim packing 371 fitted to the rim 312 of the lid body 310 as shown in Fig. And a lower packing 374 disposed inside the upper end 213 of the container 200 are integrally formed.

5, the rim packing 371 includes an upper flange 371a and a lower flange 371b, an upper flange 371a and a lower flange 371b disposed on the upper and lower surfaces of the rim 312 of the lid body 310, 371b.

The wing packing 373 extends obliquely from the lower surface of the rim packing 371 as shown in Figs. 4 and 5.

When the lid 300 is placed on the upper end 231 of the container 200 when the lid 300 is closed, the wing packing 373 is pushed down by the weight of the lid 300, And serves as a vacuum pumping packing which is evacuated into a vacuum state between the wing packing 373 and the upper end 231.

In addition, grooves may be formed on the bottom surface of the lower flange 371b or on the upper surface of the vane packing 373 at predetermined intervals along the circumference.

These grooves provide the function of a return space to provide a return force when the underside of the lower flange 371b and the upper surface of the vane packing 373 are in close contact with each other and return to their original state.

That is, when the contact area is reduced as much as the grooves are formed, the inner vacuum state of the container 200 can be maintained at a constant level because of the flat contact, and the recesses, It spreads well and falls well.

5, the groove has a first groove 380 formed on the upper surface of the wing packing 373 and a second groove 382 formed on the lower surface of the lower flange 371b according to the present embodiment.

Particularly, the second groove 382 is arranged between the first groove 380 and the first groove 380 in a zigzag manner.

The zigzag arrangement is very easy to return to the original state because it can be widened to the surface area of the return space while keeping the plane contact at a minimum.

The first contact surface 380a of the first groove 380 is arranged on the second groove 382 in a zigzag manner so that the first groove 380 and the second groove 382 partially overlap with each other as in this embodiment. And the second contact surface 382a of the second groove 382 is placed on the first groove 382 so that reliable return can be made with minimal plane contact.

Furthermore, the bottom surface of the lower flange 371b has a downwardly convex round surface 385. [

When the convex round surface 385 is in close contact with the upper surface of the vane packing 373, the convex round surface 385 is pressed against the upper end 231 of the container 200 as shown in FIG.

When released from such a closed holding state, the convex round surface 385 pushes the upper surface of the vane packing 373 by reliably expanding the lid body 310 close to the rigid body and restoring the original shape, .

The supporting member 390 includes an upper frame 391 that presses the upper surface of the upper flange 371a of the packing 370 and a lower frame 391 that extends downward from the outer side of the upper frame 391, A corner bead 395 that supports the corners of the web 371c and the lower flange 371b by being pushed inward from the first outer frame 393 and a corner bead 395 And a second outer frame 397 extending beyond the upper end 231 of the container 200.

Since the molding of the corner beads 395 is performed by rolling and most of all the molding of the corner beads 395 does not affect the packing 370 and the lid body 310 and particularly the tempered glass lid body 310, It is possible to reliably prevent water leakage and damage to the glass lid body due to warping of the packing 370 caused by rolling.

On the other hand, the lower packing 374 extends downward from the lower surface of the rim packing 371 and is disposed inside the upper end 231 of the container 200 (see Fig. 3).

This downward packing 374 serves as a guide to the interior of the container 200 when the lid 300 is closed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. It will be apparent to those skilled in the art.
