Description

The present invention relates to a cooking container with an automatic vacuum function. More specifically, the food container is stored so as not to be spoiled for a long time by automatically switching the inside of the cooking container to a vacuum state by using air contraction due to a temperature drop after heating. Further, the present invention relates to a cooking vessel with an automatic vacuum function that can maintain a vacuum state for a longer period of time because a more perfect sealing is possible by improving the cross-sectional configuration of the packing.

Generally, a cooking container is provided with a container main body provided with a storage space in which food can be placed, and a lid for sealing the upper part of the container main body. The cooking container having such a configuration is widely used, and is generally used for cooking soup, Korean food stew, and the like.

The food cooked in such a cooking container has no problem if it is eaten immediately, but if it cannot be eaten immediately depending on the situation, external air flows in through the gap from the structure of the cooking container. Due to its nature, it is easy to rot, especially on a hot day, and cannot be stored for a long time, thereby increasing the waste of food.

For this reason, the cooker refrigerates and reheats the cooked food before it cools to prevent spoilage.In this case, too, energy is wasted and the cooker forgets If you don't take action, you will rot.

The present invention has been made to solve the above-mentioned problems, and the purpose thereof is to store food so that the food is not spoiled for a long time by automatically switching the inside of the cooking container to a vacuum state. Since a more perfect sealing is possible, it is an object of the present invention to provide a cooking vessel with an automatic vacuum function that can maintain a vacuum state for a longer time.

In order to achieve the above-described object, the cooking container with an automatic vacuum function according to the present invention is provided with an accommodation space that is open on the inside, and a mounting portion that is bent outward on the upper surface. The container main body and the container main body are mounted on a mounting portion. A vacuum release valve is provided on the upper surface, and a flange portion mounted on the mounting portion is extended on the peripheral portion. A lid body formed with a ring projection projecting in the vertical direction on the inner side of the flange portion, an annular trunk body fitted to an outer circumferential edge of the ring projection of the lid body, and an outer circumferential edge of the trunk body A first contact piece integrally formed on the upper part, a second contact piece formed on the lower side of the first contact piece, the tip of which is separated from the tip of the first contact piece by a certain distance; and The lid formed on the lower side of the second contact piece and in close contact with the slope formed in the bent portion of the container body Comprising and a packing made of inclined surfaces to further enhance the sealing force as to prevent the idler.

Preferably, the vacuum release valve is fitted into a mounting hole formed on an upper surface of the lid body, a pressure discharge space is provided inside, and the mounting hole is provided on the outer peripheral edge of the upper and lower parts. First and second flange portions that are hermetically sealed and spaced apart from each other by a certain distance so as not to be detached from the mounting hole are formed, and the upper side of the second flange protrudes outside the lid when discharged to discharge pressure. The fuselage is formed on the upper surface of the fuselage, and is formed on the upper surface of the fuselage so that it is thinner than other parts of the fuselage and is crimped during vacuum so that the user can easily see the vacuum state. A vacuum display unit.

According to the cooking container with an automatic vacuum function according to the present invention, the lid body completely blocks the inflow of external air through the packing in the cooling process after heating, so that the inside of the container body is automatically brought into a vacuum state. By switching, the food can be stored so as not to be spoiled for a long time, and the packing structure comprising the body, the first and second contact pieces formed on the outer peripheral edge of the body and the inclined surface is more perfect. Since sealing becomes possible, there is an advantage that the vacuum state can be maintained for a longer time.

"A" and "b" are schematic longitudinal cross-sectional views which show the action | operation of the cooking container with an automatic vacuum function by one suitable embodiment of this invention.

Hereinafter, a cooking container with an automatic vacuum function according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a cooking container with an automatic vacuum function according to a preferred embodiment of the present invention, and FIG. 2 is an exploded perspective view of a cooking container with an automatic vacuum function according to a preferred embodiment of the present invention. .

Referring to FIGS. 1 and 2, a cooking container 100 with an automatic vacuum function according to the present invention is large and includes a container body 110, a lid 120, and a packing 130.

First, the container main body 110 is opened to the upper side to form an accommodation space 112 for storing food, and an upper surface is formed with a placing portion 114 that is bent outward. It is preferable to form a prevention claw 118 that is bent upward from the portion 114 to prevent overflow. At this time, the bent portion 116 generated in the bending process of the mounting portion 114 is formed to have a rounded angle instead of a right angle as shown in the enlarged sectional view of FIG. A gripping portion (not shown) can be installed on both sides of the container body 110 so as to be easily gripped.

Next, the lid 120 is placed so as to be placed on the placement portion 114 of the container body 110 and hermetically seal the upper portion. As shown in the enlarged sectional view of FIG. A vacuum release valve 122 is provided on the upper surface of the inner surface of the first and second flange portions 128 mounted on the mounting portion 114. The flange portion 128 is extended on the peripheral portion, and a ring projecting vertically from the inner side of the flange portion 128. A protrusion 129 is formed. A gripping portion S is provided at the center of the lid 120.

At this time, the manufacturing method of the lid 120 includes a casting method and a forging method. However, it is preferable that the lid 120 according to the present invention is manufactured by a casting method out of two methods. This is because the flange portion 128 formed on the peripheral edge portion of the lid 120 and the ring protrusion 129 protruding in the vertical direction on the inside thereof realize a substantially “L” shape having more accurate horizontal and vertical. is there. The reason is easy to understand when compared with the forging method, that is, the forging method is a method of striking or warping raw materials to produce a desired shape, and if the lid 120 is manufactured by the forging method, it is relatively Of course, it is difficult to form the flange portion 128 and the ring projection 129 having accurate horizontal and vertical directions. Accordingly, since the flange portion 128 and the ring protrusion 129 cannot have a regular shape, the packing fitted here may easily fall off. For this reason, when the lid 120 is manufactured by the forging method, at least one packing mounting groove must be formed in either the flange portion 128 or the ring protrusion 129.

However, unlike the forging method, the casting method is produced by casting a raw material melted in a mold, so that a relatively accurate horizontal and vertical flange portion 128 and an annular protrusion 129 can be formed. It can be done. In other words, according to the casting method, the flange portion 128 and the ring protrusion 129 can be regularly formed. Therefore, if the packing 130 having an inner diameter that matches the outer diameter of the ring protrusion 129 is manufactured, the packing 130 Therefore, it is not necessary to form a separate mounting groove for preventing the dropout of the metal. For this reason, it should be recognized that the structure of the lid can be more easily manufactured by adopting a casting method when manufacturing the lid 120.

The vacuum release valve 122 is attached to the upper surface of the lid 120. As will be described later, the vacuum release valve 122 discharges the internal pressure to the outside when the container body 110 is heated, and is arranged so that it can be released when the inside is switched to a vacuum state. Is as follows. Prior to describing the structure of the vacuum release valve, a mounting hole 121 for mounting the vacuum release valve 122 is formed on the upper surface of the lid 120 as schematically shown in a partially enlarged view of FIG. It must be recognized that

That is, as shown in the enlarged view of FIG. 2, the vacuum release valve 122 is large and includes a body 123 and a vacuum display unit 127. First, the body 123 is formed on the upper surface of the lid 120. It is fitted into the mounting hole 121 and has a pressure discharge space 124 inside. The mounting hole 121 is sealed at the outer peripheral edge of the upper and lower parts and is not separated from the mounting hole 121 by a certain distance. Separated first and second flange portions 125a and 125b are formed, respectively, and a discharge hole 126 is formed above the second flange 125b so as to protrude from the lid 120 and discharge pressure when it is raised. The vacuum display unit 127 is formed on the upper surface of the body 123, but is thinner than the other parts of the body 123. This is arranged so that it can be crimped inward during vacuum so that the user can easily see the vacuum.

Further, as shown in the enlarged view of FIG. 2, the packing 130 is integrally formed with an annular body 132 fitted to the outer peripheral edge of the ring protrusion 129 of the lid 120 and an upper part of the outer peripheral edge of the body 132. The formed first contact piece 134, the second contact piece 136 formed below the first contact piece 134, the tip of which is separated from the tip of the first contact piece 134 by a certain distance, An inclined surface 138 that is formed below the second contact piece 136 and is in close contact with the inclination formed in the bent portion 116 of the container body 110 to prevent the lid 120 from moving and to further increase the sealing force. Become. At this time, since the tip of the second contact piece 136 is separated from the tip of the first contact piece 134 by a certain distance, it is very obvious that a buffering groove is formed between the two contact pieces. is there.

Hereinafter, the connection relationship and operation of the container main body 110, the lid 120, and the packing 130 having the above-described configuration will be described.

FIG. 3 is a combined longitudinal cross-sectional view of a cooking vessel with an automatic vacuum function according to a preferred embodiment of the present invention, wherein “a” and “b” in FIG. 4 represent an automatic vacuum according to a preferred embodiment of the present invention. It is a schematic longitudinal cross-sectional view which shows the action | operation of the cooking container with a function.

First, referring to FIG. 3, a lid body 120 having a packing 130 fitted on the outer peripheral edge of the ring projection 129 is placed on the placement portion 114 of the container body 110 to seal the upper portion. That is, referring to a partially enlarged view, the inclined surface 138 of the packing 130 attached to the outer peripheral edge of the ring protrusion 129 of the lid 120 is brought into close contact with the bent portion 116 of the mounting portion 114 of the container body 110. I understand that.

Meanwhile, the groove formed between the first and second contact pieces 134 and 136 formed on the body 132 of the packing 130 acts as a buffer, so that the mounting process of the lid 120 is smoother. Needless to say.

The cooking container 100 with an automatic vacuum function according to the present invention thus combined is operated as shown in FIG. That is, referring to “a”, when the container main body 110 is heated for a predetermined time with the lid 120 placed on the upper portion of the container main body 110, that is, on the placement portion 114, the high pressure is reduced by the vacuum release valve due to the rise in internal temperature. 122 is raised and discharged to the outside through the discharge hole 126. At this time, even if the vacuum release valve 122 is raised by high atmospheric pressure, the second flange portion 125b formed on the lower surface will be in close contact with the inner surface of the lid 120 and will not fall off. When the high atmospheric pressure inside the container main body 110 is higher than the exhaust speed, the entire lid 120 is pushed up and discharged to the space formed between the placement portion 114 of the container main body 110 and the packing 130. Let's go.

Continuing, referring to “b”, when cooking is completed and the container body 110 is no longer heated, the internal temperature gradually cools and changes to low pressure. At this time, the vacuum release valve 122 that has been moved up due to the high atmospheric pressure is further moved down and is brought into close contact with the upper surface of the mounting hole 121 of the lid 120 via the first flange portion 125a to block the inflow of external air. The body 120 is also in close contact with the mounting portion 114 of the container body 110 according to the same principle to block inflow of external air. Here, the inclined surface of the packing 130 attached to the outer peripheral edge of the ring protrusion 129 of the lid 120 138 is further brought into close contact with the bent portion 116 of the mounting portion 114 of the container body 110. At the same time, the first contact piece 134 moves downward toward the second contact piece 136, that is, the first and second contact portions. The grooves formed between the pieces 134, 136 will be more closely adhered while shrinking to maintain a more perfect hermetic seal. Then, this low atmospheric pressure compresses the vacuum display portion 127 formed on the upper surface of the vacuum release valve 122 downward, as shown in a partially enlarged view, that is, sucks the inside of the container body 110 from the outside in a vacuum state. Make things visible.

If the inside of the container main body 110 is automatically switched to a vacuum state after heating by such an operation, the external air cannot flow into the container main body 110. Consequently, the container main body 110 is similar to various known cans. It becomes a new vacuum storage sealed container. For this reason, since the air communication between the outside air and the inside of the container main body 110 is blocked, the food cannot cause an oxidation reaction and can be stored for a long time.

In this state, it is natural that the container body 110 and the lid body 120 are not easily separated unless air flows into the interior. Therefore, when the user wants to eat food stored in the container body 110, the user releases the vacuum. It is necessary to take an action of grasping the upper part of the valve 122 and raising it upward. That is, when the vacuum release valve 122 rises upward, the external air is quickly flowed into the container main body 110 through the discharge hole 126 protruding from the upper portion of the attachment hole 121 of the lid 120, and immediately the container main body 110. The inside of the vacuum is released. Then, the user should just remove the cover body 120 from the container main body 110, and use it like a normal cooking container. When the vacuum is released, the vacuum indicator 127 of the vacuum release valve 122 will return to the original state.

For this reason, according to the cooking container 100 with an automatic vacuum function according to the present invention, the lid 120 completely blocks the inflow of external air through the packing 130 during the cooling process after heating. By automatically switching to a vacuum state, the food can be stored so as not to be spoiled for a long time, and the body 132, and first and second contact pieces 134, 136 formed on the outer periphery of the body 132, and Since a more perfect sealing is possible by the structure of the packing 130 formed of the inclined surface 138, there is an advantage that the vacuum state can be maintained for a longer time.
