Description

Packing for vacuum pot lid "

The present invention relates to a packing for a lid of a vacuumable pot which is detachably mounted on a mounting groove of a lid body, and more particularly to a packing for a lid of a vacuumable pot which reliably prevents disengagement during vacuum release.

When boiling, a pot that can be vacuumed is used as a pot as usual while the inside of the cooking chamber expands and air is discharged through a check valve.

After boiling, the inside of the cooking chamber shrinks, blocking the inflow of outside air through the check valve, and functioning like a so-called pumping that keeps the lid down, while vacuuming the inside of the cooking chamber so that the lid does not fall off the container .

If the contents are kept in this vacuum state, it is possible to prevent the food from being broken while the vacuum is maintained, thereby solving the inconvenience of continuously boiling and storing.

Release the vacuum again by boiling or holding the check valve.

As this type of pot, it is proposed to be known from the following patent documents.

The packing 100 of Patent Document 7 has a ring shape. On one side of the packing 100, first and second contact pieces 120 and 122 are formed on upper and lower portions by a cutout 110 formed along the shape of a packing, A plurality of protrusions 130 are annularly arranged on the contact surface of at least one of the first and second contact pieces 120 and 122 so as to be easily restored to the original state by reducing the surface area of the cut- .

7, the lower edge of the lid 24 that seals the upper portion of the container body 22 of the cooking container 20, that is, the lower side of the flange portion 25 formed on the lid 24, Is fitted to the outer periphery of the ring protrusion (26) formed on the inner side and is brought into close contact with the upper part of the container main body (22).

In this state, when the food is put into the container body 22 and heated, the high pressure inside the container body 22 is discharged through the gap generated by the vacuum release valve 28 and the lid 24, When the container body 22 is no longer heated, the temperature inside the container body 22 gradually cools down to a low pressure. In this process, the lid 24 is contracted by the contraction of the cut- The first contact piece 120 and the second contact piece 122 adhere to each other while closely adhering to the upper surface of the container body 22 to block the inflow of external air, thereby turning the inside of the container body 22 into a vacuum state.

On the other hand, the packing 100 of Patent Document 2 has a ring shape. On one side of the packing 100, first and second contact pieces 120 and 122 are formed on upper and lower portions by a cutout 110 formed along the shape of a packing, A plurality of protrusions 130 are arranged in an annular shape so as to be easily restored to the original shape by reducing the surface area of the first and second contact pieces 120 and 122 that are in contact with each other at the time of the contraction of the cut- .

3, the lower edge of the lid 24 that seals the upper portion of the container body 22 of the cooking container 20, that is, the lower side of the flange portion 25 formed on the lid 24, Is fitted to the outer periphery of the ring protrusion (26) formed on the inner side and is brought into close contact with the upper part of the container main body (22).

In this state, when the food is put into the container body 22 and heated, the high pressure inside the container body 22 is discharged through the gap generated by the vacuum release valve 28 and the lid 24, When the container body 22 is no longer heated, the temperature inside the container body 22 gradually cools down to a low pressure. In this process, the lid 24 is contracted by the contraction of the cut- The first contact piece 120 and the second contact piece 122 adhere to each other while closely adhering to the upper surface of the container body 22 to block the inflow of external air, thereby turning the inside of the container body 22 into a vacuum state.

However, the packing 100 of Patent Document 1 is mounted in such a way that it is likely to be separated from the lid 24.

On the other hand, the packing 370 of Patent Document 2 is attached to a mounting groove 350 formed at the rim of the lid body 310 as shown in Fig.

The mounting groove 350 has an upper bending piece 351 bent upward from the rim of the lid body 310, an outer horizontal bending piece 353 bent outward horizontally from the upper bending piece 351, And a downward bending piece 355 bent downward from the outer horizontal bending piece 353.

Since the packing 370 is inserted and mounted in the mounting groove 350, the outer side and the inner side and the upper side constrain the packing 370 to reliably prevent the outward departure due to the expansion due to heat.

An engaging protrusion 356 is formed on the inner surface of the downward bending piece 355 so that the lower front end 371a of the packing body 371 is caught.

Thus, the packing 370 prevents the packing 370 from being caught by the latching jaw 356, thereby surely preventing any disconnection of the packing 370 in any direction even when the vacuumable lid 300 is continuously opened and closed.

As shown in Fig. 8, the packing 370 is an integral ring of a closed loop, and includes a packing body 371 and a packing wing 373 supported on the rear end side so as to be vertically movable up and down with respect to the packing body 371 Consists of.

Between the front end and the rear end of the lower surface of the packing main body 371 is formed a bent tip 375 projecting downward so that the packing wing 373 comes into line contact with the bent tip 375, So as to suppress the sticking to the utmost.

However, the packings of Patent Document 1 and Patent Document 2 are all mounted on the ring protrusion 26 or the mounting groove 350 in close contact with each other.

In addition, since the packing has to be expanded to some extent in the mounting groove when heat is received, the packing must be allowed to expand.

Due to such a margin for allowing expansion, water vapor or food or the like enters between the packing and the mounting groove, or between the packing and the ring projection, and the steam or food acts like lubricating oil, and the packing tends to separate from the mounting groove.

In addition, since the repulsive force is applied to the upper surface and the side surface when the packing is mounted, there is a great fear that the packing will not have a repulsive force to push up the packing.

Patent Document 1: Korean Utility Model Registration No. 20-0451215 Patent Document 2: Korean Patent Publication No. 10-1291330

It is an object of the present invention to provide a packing for a lid of a vacuumable pot which can prevent the intrusion of foreign matter while firmly preventing the disconnection of the packing by utilizing the repelling preventing repulsive force of the packing .

In order to achieve the above-mentioned object, a packing for a lid of a vacuum-enabled pot according to claim 1 of the present invention is a packing for a lid of a pot which enables the interior of the container to be vacuumed, And the packing body is formed with a protrusion protruding outwardly from the packing body.

In the packing for a lid of the vacuum-enabled pot according to claim 2 of the present invention, the projection extends and slopes downward from the inner surface of the packing body.

In the packing for a lid of the vacuum-enabled pot according to claim 3 of the present invention, the projection extends and protrudes from the outer surface of the packing body.

The packing for a lid of a vacuum-enabled pot according to claim 4 of the present invention is characterized in that the protrusion has a first projection protruding downward from the inner surface of the packing body in an inclined manner and a second projection protruding from the outer surface of the packing body, .

In the packing for a lid of the vacuum-enabled pot according to claim 5 of the present invention, the lower surface of the packing body is formed with a convex groove portion and a convex downward convex portion.

In a packing for a lid of a vacuum-enabled pot according to claim 6 of the present invention, a protruding rib is formed on an upper surface of the packing wing so as to be in contact with the protruding portion. The protruding rib has a circular arc shape convex upward between the outer side and the inner side of the packing wing to be.

The present invention has the following effects.

(Protrusions or second protrusions) protruding from the inner surface or the outer surface of the packing body are formed so that the protrusions are compressed when the protrusions are mounted on the mounting grooves and are supported by the repulsive force, do.

Further, a space is formed between the mounting groove and the inner surface of the packing body or between the mounting groove and the outer surface of the packing body by the length of the protruded projection after being compressed, thereby enabling the packing of the packing when heating through this space.

Particularly, a protrusion extending obliquely downward is formed on the inner surface of the packing body, so that the protrusion is compressed when the protrusion is mounted on the mounting groove, thereby pushing upward the repelling force, further preventing the packing from being arbitrarily disengaged from the mounting groove.

In addition, since the protrusion relatively thinner than the packing body is compressed in the mounting groove, the amount of compression is increased, and foreign matter is prevented from penetrating into the clearance by the large amount of compression so that the packing can be stably mounted in the mounting groove .

On the other hand, convex grooves are formed on the lower side of the lower surface of the packing body and convex portions are formed downward on the lower side of the packing body. As a result, the packing wings are easily separated from the lower surface of the packing body due to limited contact with the protrusions, (That is, the returnability of the packing wing is good).

Particularly, by forming the projecting rib in contact with the projecting portion on the upper surface of the packing wing in the shape of an arc, the vacuum efficiency can be increased due to the rise of the cushion upon vacuum suction, and quick return can be made when the vacuum is released.

1 and 2, a vacuumable pot 1000 according to the present invention includes a container 1200 having a cooking chamber 1200a, a vacuum lid (not shown) for opening and closing the cooking chamber 1200a of the container 1200 1300).

The container 1200 is formed by a bottom 1210 and a side wall 1230 protruding from the edge of the bottom 1210 so as to form a cooking chamber 1200a therein as shown in FIG.

The vacuumable lid 1300 includes a lid body 1310 as well as a check valve 1350 mounted on the lid body 1310 as shown in Figures 2, A groove 1360, and a packing 1370 mounted to the mounting groove 1360.

Particularly, the check valve 1350 is mounted on a lid handle 1330 provided in a through hole 1311 formed through the center of the lid body 1310.

As shown in Figs. 3, 6A and 6B, the lid handle 1330 includes a hollow core portion 1330a disposed on the through hole 1311, and a hollow core portion 1330b joined to the lid body 1310 in combination with the hollow core portion 1330a. And an arm 1330c protruding in the radial direction of the lid body 1310 from one side of the hollow cap portion 1330b. Further, the lid handle 1330 is formed of a plastic material resistant to heat.

The check valve 1350 is vertically movably fitted in the hollow core portion 1330a and the upper portion of the check valve 1350 protrudes above the upper end of the hollow cap portion 1330b.

With the configuration of the lid handle 1330, the lid handle 1330 can simultaneously satisfy the vacuum function, the overflow prevention function, and the lifting function.

The penetrating inside of the hollow core portion 1330a functions as a passage for discharging the water vapor generated in the container 1200 as shown in FIG. 6B.

At the lower end of the hollow core portion 1330a, a latching flange 1331a is formed which is hooked on the bottom surface of the lid body 1310. [

The engaging flange 1331a is caught by the lower surface of the through hole 1311 when the upper end of the hollow core 1330a is inserted from below to above the through hole 1311. [

A male screw 1333a is formed on the outer peripheral surface of the hollow core 1330a. Since this male screw thread 1330a is formed between the engagement flange 1331a and the upper end of the hollow core 1330a, there is a difference in height between the upper end of the hollow core 1330a and the through hole 1311 to some extent.

The hollow cap portion 1330b has a cylindrical or cylindrical shape penetrating up and down, and a female screw thread 1333b fastened to the male screw thread 1333a is formed on the inner circumferential surface.

The female screw 1333b is also formed between the lower end and the upper end of the hollow cap portion 1330b.

Therefore, the height between the upper and lower ends of the hollow cap portion 1330b is somewhat deep.

The arm 1330c protrudes in the radial direction of the lid body 1310 from one side of the hollow cap portion 1330b when viewed from the plane and is inclined upward toward the rim from the center side of the lid body 1310 when viewed from the side .

Thus, the end of the arm 1330c and the rim of the lid body 1310 can stably raise the lid 1300 that can be vacuumed.

Meanwhile, as shown in FIGS. 6A and 6B, the hollow cap portion 1330b is provided with a guide piece 1340 for guiding upward the steam.

Particularly, the guide piece 1340 is disposed at a position where the hollow cap part 1330b meets the arm 1330c, and functions as a detour to bypass the upward direct water vapor or the like toward the arm 1330c.

In order to function as a detour, a guide piece 1340 is provided on a part of the upper surface of the hollow cap part 1330b so as to surround the wall.

The check valve 1350 is a silicone material free from elastic deformation and harmless to the human body and has an opening and closing flange 1351 placed on the upper surface 1337a of the opening and closing hole 1335a formed in the hollow core 1330a as shown in Figs. 6A and 6B. A hollow flange 1355 attached to the lower surface 1338a of the opening and closing hole 1335a and a hollow flange 1355 formed in the upper portion of the opening and closing flange 1351, And a flange 1359 formed between the stem 1353 and the opening and closing flange 1351. The flange 1359 is formed of a metal plate.

The connection portion 1357 is implemented as a plurality of connection strips 1357 provided at predetermined intervals so as to form a discharge space S along the periphery of the hollow flange 1355.

The shape of the stopper 1353 may be hand-held.

The opening and closing flange 1351 is of a flange type protruding outward from the bottom of the stem 1353 so as to have a diameter larger than the diameter of the opening and closing hole 1335a.

The hollow flange 1355 has a disk shape and a through hole 1356 formed at the center thereof.

With this configuration, the check valve 1350 forms a flow path through which the pressure inside the cooking chamber 1200a is discharged to the outside through the through hole 1336 and the discharge space S of the hollow flange 1335c, The flow path is a one-way valve that blocks.

On the other hand, the diameter of the flange 1359 is larger than that of the opening / closing flange 1351 to function as an umbrella again to make the diameter smaller than the diameter of the through hole of the hollow cap portion 1330b, desirable.

That is, the flange 1359 functions as an umbrella for minimizing overflow when the foreign object overflows through the opening / closing flange 1351.

On the other hand, as shown in Figs. 6A and 6B, it is preferable that a plurality of holes 1359a are formed in the flange 1359. 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 1359a serves as a discharge 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 gap c.

The packing 1370 is an integral ring of a closed loop and has a packing body 1371 and a packing body 1371 as shown in Figs. 3A, 4, 4A and 5, And a packing wing 1373 supported by the packing 1373.

Further, the packing body 1371 is formed with projecting protrusions.

That is, the protrusion is constituted by a first protrusion 1377 extending or protruded from the inner surface of the packing body 1371 or a second protrusion 1378 extending or protruding from the outer surface of the packing body 1371, or a combination thereof.

Particularly, the first projection 1377 is extended and protruded downward from the inner surface of the packing body 1371.

More specifically, the first protrusion 1377 protrudes downward in the form of a tail at the inner surface of the packing body 1371 or at the point where the packing body 1371 and the packing wing 1373 meet.

This first projection 1377 causes the first projection 1377 to elastically compress against the wall of the upward bending piece 1361 when the packing 1370 is mounted on the mounting groove 1360. [

The first projection 1377 receives upward repulsive force with respect to the upward bending piece 1361 to prevent the packing 1370 from being arbitrarily disengaged from the mounting groove 1360. [

Since the downward first protrusion 1377 is relatively thinner than the packing body 1371 and the elastic compression is so great that the intrusion of foreign matter between the first protrusion 1377 and the wall of the upward bending piece 1361 It is very hard.

Therefore, the packing 1370 does not slip due to the intrusion of foreign matter, so that the packing 1370 can be freely disengaged from the mounting groove 1360.

The first protrusion 1377 forms a first space 1377a between the inner side surface of the packing body 1371 and the upward bent piece 1361.

The first space 1377a not only facilitates the mounting of the packing body 1371 into the mounting groove 1360 but also serves as an extra space for the packing body 1371 to thermally expand.

On the other hand, the second projection 1378 extends from the outer surface of the packing body 1371.

The second projection 1378 causes the second projection 1378 to elastically compress against the wall of the lower bending piece 1365 when the packing 1370 is mounted on the mounting groove 1360. [

Particularly, the second projection 1378 is hooked on the latching jaw 1366.

Therefore, the second projection 1378 is formed to be caught by the engagement protrusion 1366 while receiving a repulsive force with respect to the downward bending piece 1365, so that even if the second projection 1378 protrudes horizontally without being inclined downward like the second projection 1377, 1370 are prevented from being arbitrarily disengaged from the mounting groove 1360.

In addition, since the second projection 1378 is relatively thinner than the packing body 1371 and the elastic compression is very large, entry of foreign matter between the second projection 1378 and the wall of the downward bending portion 1365 is very difficult.

Therefore, the packing 1370 does not slip due to the intrusion of foreign matter, so that the packing 1370 can be freely disengaged from the mounting groove 1360.

The second projection 1378 also forms a second space 1378a between the outer surface of the packing body 1371 and the lower bent piece 1365.

The second space 1378a also facilitates the mounting of the packing body 1371 into the mounting groove 1360 as well as the first space 1377a and also serves as an extra space for thermal expansion of the packing body 1371 .

On the other hand, it is preferable that the lower surface of the packing body 1371 is formed with a convex groove portion 1371a and a downward convex projection portion 1371b.

The groove portion 1371a has a semicircular shape and provides elasticity when the packing wing 1373 is in contact with the packing body 1371 so as to quickly and accurately perform the vacuum release.

The protruding portion 1371b serves to minimize sticking of the packing wing 1373 to the lower surface of the packing body 1371. [

Particularly, the upper surface of the packing wing 1373 is further provided with a protruding rib 1375 which is in contact with the protruding portion 1371b, so that it is possible to reduce the contact area and prevent the sticking phenomenon.

The protruding rib 1375 preferably has an arc shape convex upward between the outside and the inside of the packing blade 1373.

The arc-shaped protruding ribs 1375 provide a cushioning function that elastically deforms from the center to the inside and outside in contact with the protruding portion 1371b, thereby enhancing the vacuum efficiency by a large cushion It is possible to promptly release the vacuum by the repulsive force according to the cushion.

The protruding ribs 1375 may be formed at predetermined intervals along the circumference of the packing wings 1373 as shown in FIG.

The mounting groove 1360 includes an upward bending piece 1361 bent upward from the rim of the lid body 1310 and an outer horizontal bending piece 1363 bent outward horizontally from the upward bending piece 1361, And a downward bending piece 1365 bent downward from the outer horizontal bending piece 1363.

Since the packing 1370 is inserted and mounted in the mounting groove 1360, the outer side and the inner side and the upper side constrain the packing 1370 to reliably prevent the outward departure due to the expansion due to heat.

Particularly, on the inner surface of the downward bending piece 1365, a stopping jaw 1366 for hooking the outer side of the packing body 1371 is further formed.

The packing 1370 thus reliably prevents any deviation in any direction of the packing 1370 even when the vacuum-enabled lid 1300 is continuously opened and closed by the configuration of the latching jaw 1366 and the protrusion 1377.

The engaging jaw 1366 can be pressed inwardly from the outside of the upper end and the lower end of the downward bending piece 1365 by a press in a very simple process.

Since the mounting groove 1360 is formed in an inverted U-shape, the mounting groove 1360 covers the inside and outside of the upper end 1231 of the side wall 1230 of the container 1200. Therefore, the inflow of air from the outside to the inside is minimized, Maintenance time) can be remarkably increased.

6B). When the pot 1000 does not boil, the inner pressure of the container 1200 is increased while the inner pressure of the container 1200 is lowered The inner pressure is contracted while the vacuum-enabled lid 1300 and the check valve 1350 are pulled.

That is, when the vacuumable lid 1300 is pulled, the internal air of the container 1200 is evacuated between the packing wing 1373 and the upper end 1231 of the container 1200 to evacuate the interior.

Accordingly, the packing wing 1373 and the check valve 1350 are made free of external air to form the cooking chamber 1200a of the pot in a vacuum state (see FIG. 6A).

The release of the vacuum state may be boiled or held by holding the stem 1353 of the check valve 1350 for a short period of time.

On the other hand, with the configuration of the check valve 1350, the lid 1300 which can be vacuumed when the cooking is boiled overflows to the upper end 1231 of the container 1200 in the middle of the sound.

To prevent this, it is preferable that a lid locking member 1700 is further provided on the container handle 1500 installed in the container 1200.

The container handle 1500 is screwed to the side wall 1230 of the container 1200.

The lid locking member 1700 comprises a locking slider 1710 and a guide member 1730 for radially guiding the locking slider 1710 with respect to the container handle 1500 as shown in Figs.

Further, it is preferable that the guide member 1730 is further provided with an elastic clip (not shown) for determining the position of the locking slider 1710.

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.
