Hereinafter, the configuration and operation of the preferred embodiment of the present invention with reference to the accompanying drawings in detail as follows.

Here, it should be noted that in adding reference numerals to the elements of each drawing, the same elements are denoted by the same reference numerals as much as possible even if they are shown on different drawings.

Referring to FIG. 1, the cooking container 100 according to an exemplary embodiment of the present invention includes a main body 110, a flange 120, and a steam exhaust 130.

Referring to the configuration of the present invention in detail as follows.

The main body 110 constitutes the main body of the cooking container 100, and is provided with a storage space 111 having an upper side open so as to contain contents to be cooked. The main body 110 may be formed of a synthetic resin material.

Specifically, the main body 110 may be formed in a shape in which a plurality of corners are rounded when viewed in a plane, and specifically, the plurality of corners may be formed within three to five, and four corners are formed in quadrangles. It may be shaped.

In addition, the connection portion of the inner side and the bottom surface of the main body 110 is formed to be round, specifically, the round may be formed within 5R. That is, as the storage space in the main body 110 is rounded, it is possible to prevent the steam pressure generated during heating cooking from concentrating on the corners other than the steam discharge unit 130.

In this case, the bottom surface of the main body 110 may be provided with a protrusion 113 protruding to the upper portion. That is, the protrusion 113 spaces the contents stored in the main body 110 by a predetermined height from the bottom surface. The protrusion 113 may be cooked so that the contents are cooked evenly through the protrusion 113.

The flange portion 120 extends outward from the upper edge of the main body portion 110 and has a width of a predetermined width. The lead film 200 (see FIG. 5A) is attached to the flange part 120 to seal and package the contents stored in the accommodation space 111.

In detail, the lead film adhesive protrusion 121 having a single closed curve shape protrudes from the upper surface of the flange part 120 so that the lead film 200 may be easily sealed and bonded. The protrusion 121 is formed to have a predetermined width, and the first adhesive surface 121a is formed flat on the upper surface of the protrusion 121 so that the lead film 200 can be easily bonded.

As the adhesive protrusion 121 is formed, the contents are introduced into the container and then when the lead film 200 is sealed, the contents flow down from the adhesive protrusion 121 on the upper portion of the flange portion, thereby preventing the contents of the lead film 200. The sealing stability can be improved.

In this case, the protrusion thickness of the protrusion 121 is at least 1 mm, and a subtraction gradient of 1 ° or more is applied to the upper portion to facilitate thermoforming using a mold. In addition, the first adhesive surface 121a may be formed to be at least 1 mm.

Referring to FIG. 2, the steam discharge unit 130 is formed so that the discharge port 131 is connected to the protrusion 121 provided on the upper surface of the flange part 120, so that steam generated in the storage space during the heating cooking is a predetermined pressure. When it reaches to release the adhesive surface of the lead film 200 bursts and discharges steam.

Specifically, the steam discharge unit 130 includes a discharge port 131 having a width gradually narrowing from the inner side to the outer side when viewed in a plan view, the discharge port 131 may include a plurality in succession. In detail, the steam discharge unit 130 may have one outlet 131 formed in a 'V' shape or a 'U' shape, or two outlets 131 in a continuous 'W' shape.

That is, the outlet 131 forms a portion of the protrusion 121, but is formed to be biased toward the outside of the flange portion 120 compared to the protrusion 121 so that steam in the storage space 111 is concentrated toward the outlet 131. Can be induced.

Referring to FIGS. 3 and 4, the second adhesive surface 131a which is connected to the first adhesive surface 121a of the protrusion 121 is formed on the upper surface of the discharge port 131 to enable the sealing adhesion of the lead film 200. Is formed.

In this case, the inlet 131 is formed with an inclined surface 131b formed to be inclined downward from the outside of the main body unit 110, and the second adhesive surface 131a formed at the outlet 131 by the inclined surface 131b is a protrusion. It is formed in a narrower width than the first adhesive surface 121a of 121.

That is, the steam generated in the storage space 111 can be smoothly guided to the discharge port 131 by the inclined surface 131b, and also has a second adhesive surface formed in a narrower width than the first adhesive surface 121a ( 131a) may be set to burst preferentially by vapor pressure. In other words, only the second adhesive surface 131a having a weaker adhesive force than the first adhesive surface 121a is broken, and the first adhesive surface 121a maintains a firm adhesive state.

Referring back to FIG. 2, the steam outlet 130 having the structure as described above may be spaced apart at least one or more, specifically, one or more four or less along the protrusion 121, and the main body 110. It may be formed in one or more of the four corners of the. That is, the steam discharge unit 130 may be disposed at the corner of the main body 110 where the steam generated in the storage space 111 is concentrated.

In addition, the auxiliary outlet 133 may be formed in the central portion of one side of the main body 110. The auxiliary outlet 133 is formed in the same shape as the outlet 131, except that the installation position is different from the outlet 131. That is, the outlet 131 serving as the main portion of the steam discharge unit 130 is first fired as it is disposed at the corner of the main body unit 110, and the secondary outlet 133 is less concentrated in the steam pressure than the outlet 131. It is disposed in the central portion of one side of the main body 110.

In other words, when it is difficult to discharge steam in the storage space 111 only by the outlet 131 due to the high steam pressure generated in the storage space 111, the auxiliary outlet 133 is set to be additionally blown out, the storage space 111. It is possible to maintain a constant pressure in the).

For example, the steam discharge unit 130 has a pair of outlets 131 disposed on both side edges of one side of the main body 110, one auxiliary outlet 133 in the center of the other side of the main body 110. ) Can be placed.

On the other hand, the lead film adhesive protrusion 121 may be further provided with a shape that is wider from the outer side to the inner side, for example, a 'V' shaped container opening part 140, and the container opening part 140 may be provided. It can be formed to maintain the width of the one adhesive surface (121a). The container opening part 140 may be formed at a central portion of one side of the main body 110 in which the vapor pressure is less concentrated than the outlet 131.

In this case, the container opening part 140 formed at the center of one side side increases the area bonded between one side of the lead film 200 and the main body 110 during heating and cooking, thereby improving the sealing force inside the container and increasing the vapor pressure. The outlet 131 can be easily torn off. In addition, as the pointed portion is formed to be biased to the outside of the protrusion 121, the user can be easily opened by pulling the lead film 200 attached to the container opening portion 140 after the heating cooking is completed.

In addition, the lead film 200 attached to the upper portion of the container opening 140 is preferably provided with a semi-circular extension (not shown) extending outward so that the user can easily open the lead film 200.

Then, the operation of the cooking container 100 provided with the steam discharge unit according to the present invention of the above configuration will be described with reference to FIGS. 5A to 5C.

First, as shown in Figure 5a, the cooking container 100 containing the food in the storage space 111 is put into a microwave oven and heated and cooked. At this time, the lead film 200 is in an unopened state.

Referring to Figure 5b, the temperature rises as the food is heated. The increase in temperature generates steam from the contents, and the generated steam increases the pressure inside the body portion 110. When the vapor pressure in the main body 110 rises, the lead film 200 starts to swell.

Referring to FIG. 5C, when the vapor pressure reaches a predetermined pressure in the main body 110, first, the adhesive surface of the lead film 200 of the outlet 131 disposed at the corner of the main body 110 is opened and opened. That is, the lead film 200 discharges steam in the storage space 111 while the second outlet 131a of the outlet 131 narrower than the first adhesive surface 121a of the protrusion 121 is blown first. become.

In this case, when the vapor pressure of the storage space 111 is high, and it is difficult to smoothly discharge steam only by the outlet 131, the auxiliary outlet 133 provided at the center of the other side of the main body 110 may be additionally blown.

Accordingly, the steam inside the main body 110 may be maintained at a constant pressure, and even after the outlet 131 is opened, the steam pressure does not drop sharply, thereby allowing the contents to be cooked smoothly.

Although the present invention has been illustrated and described with reference to certain preferred embodiments, the present invention is not limited to the above embodiments and various changes and modifications are possible without departing from the spirit of the present invention.
