It should be noted that, when adding reference numerals to the constituent elements in each drawing, the same constituent elements are represented by the same reference numeral even if they are displayed in other drawings. I have to.

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

The structure of the present invention will be described in detail below.

The main body 110 is a main body of the cooking container 100, and is provided with a storage space 111 whose upper side is opened so that the contents to be cooked can be piled up. The main body 110 is also made of a synthetic resin material.

Specifically, the main body 110 is also formed in a shape in which a plurality of corners are chamfered in a plan view, and specifically, the plurality of corners are formed in three to five. It also has a quadrangular shape with four corners formed.

At the same time, the connecting part between the inner side surface and the bottom surface of the body 110 is chamfered, and specifically, the chamfer can be formed within 5R. That is, since the storage space in the main body 110 is formed so as to be chamfered, it is possible to prevent the vapor pressure generated during cooking from being concentrated in a recessed portion other than the steam discharge portion 130.

In this case, the bottom surface of the main body 110 may be provided with a protrusion 113 that protrudes right above. That is, the protrusion 113 separates the contents stored in the main body 110 from the bottom surface by a certain height, and cooks the contents so that the contents are pushed and heated through the protrusion 113. can do.

The flange part 120 is formed to extend outward from the upper frame of the main body part 110 and has a constant width. The lid film 200 (FIG. 5A) is adhered to the flange portion 120 to hermetically package the contents stored in the storage space 111.

Specifically, on the upper surface of the flange portion 120, a lid film bonding protrusion 121 having a single closed curve shape is provided so as to be easily sealed and bonded to the lid film 200. The protrusion 121 is formed to have a constant width, and a first bonding surface 121a is formed flat on the upper surface of the protrusion 121 so that the lid film 200 can be easily bonded.

By forming such an adhesive protrusion 121, the contents flow into the inside of the container and then, when the lid film 200 is sealed, the contents flow down from the adhesive protrusion 121 on the upper portion of the flange portion. The sealing stability of the film 200 can be improved.

In this case, the protrusion thickness of the protrusion 121 is at least 1 mm or more, and a draft angle of 1° or more is applied to the upper portion so that thermoforming using a mold is easy. At the same time, the first adhesive surface 121a is formed to be at least 1 mm or more.

Referring to FIG. 2, the steam discharge part 130 is formed such that the discharge port 131 is connected to the protrusion 121 provided on the upper surface of the flange part 120, and the steam generated in the storage space during heating and cooking has a predetermined pressure. In the case of (1), vapor is discharged while the adhesive surface of the lid film 200 is peeled off and opened.

Specifically, the steam discharge part 130 includes a discharge port 131 having a shape in which the width is gradually narrowed from the inner side to the outer side in a plan view, and the plurality of the discharge ports 131 are continuously included. Specifically, in the steam discharge part 130, one discharge port 131 is formed in a “V” shape or a “U” shape, or two discharge ports 131 are continuously formed in a “W” shape. It

That is, although the discharge port 131 forms a part of the projection 121, it is formed more biased to the outside of the flange 120 than the projection 121, and the vapor in the storage space 111 is concentrated on the discharge port 131 side. Can be induced to.

Referring to FIGS. 3 and 4, a second adhesive surface 131 a connected to the first adhesive surface 121 a of the protrusion 121 is formed on the upper surface of the discharge port 131 so that the lid film 200 can be sealed and adhered. It

In this case, the outlet 131 is formed with an inclined surface 131b which is formed to incline downward from the outside of the main body 110, and the second adhesive surface 131a formed on the outlet 131 is formed by the inclined surface 131b. Is formed narrower than the first bonding surface 121a of the protrusion 121.

That is, the steam generated in the storage space 111 is smoothly guided to the discharge port 131 side along the inclined surface 131b, and at the same time, the second adhesive surface 131a formed to be narrower than the first adhesive surface 121a. However, it can be set so as to be peeled off preferentially by the vapor pressure. In other words, only the second adhesive surface 131a having a weaker adhesive force than the first adhesive surface 121a is peeled off, and the first adhesive surface 121a maintains a firm adhesive state.

Referring again to FIG. 2, the steam discharge part 130 having the above-described structure is formed along the protrusion 121 at least 1 or more, specifically, 1 or more and 4 or less. It is also formed in one or more of the four corners of the section 110. That is, it is efficient that the steam discharge unit 130 is arranged at the corner of the main body 110 where the steam generated in the storage space 111 is concentrated.

At the same time, an auxiliary discharge port 133 is formed at the center of one side of the main body 110. The auxiliary outlet 133 is also formed in the same shape as the outlet 131, but the installation position thereof is different from that of the outlet 131. That is, the discharge port 131, which plays the main role of the steam discharge unit 130, is arranged at the corner of the main body unit 110 to perform peeling operation first, and the auxiliary discharge port 133 has a lower vapor pressure than the discharge port 131. It is arranged at the center of one side of the main body 110 that is sufficiently concentrated.

In other words, when the vapor pressure generated in the storage space 111 is high and it is difficult to discharge the vapor in the storage space 111 only by the discharge port 131, the auxiliary discharge port 133 should be additionally set to perform the peeling operation. As a result, a constant pressure can be maintained in the storage space 111.

As an example, the steam discharge part 130 has a pair of discharge ports 131 arranged at both corners of one side of the main body 110 and one auxiliary discharge port 133 arranged at the center of the other side of the main body 110. can do.

On the other hand, the lid film bonding protrusion 121 further includes a container opening portion 140 having a shape in which the width increases from the outside to the inside, for example, a “V”-shaped container opening portion 140. It can be formed so as to maintain the width of the first adhesive surface 121a. The container opening portion 140 may be formed at the center of one side of the main body 110 where the vapor pressure is less concentrated than the discharge port 131.

In that case, the container opening part 140 formed in the central part of one side expands the area to be bonded between the lid film 200 and the one side of the main body 110 during heating and cooking. The internal sealing force is improved, and the exhaust port 131 is easily peeled off due to the increase in vapor pressure. At the same time, the pointed portion is formed on the outer side of the protrusion 121 so that the user can easily open the lid film 200 attached to the container opening portion 140 by pulling the lid film 200 after the cooking is completed. it can.

In addition, the lid film 200 attached to the upper portion of the container opening portion 140 has a semicircular extension formed by extending to the outside so that the user can easily remove the lid film 200 by peeling it off. Preferably (not shown) is provided.

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

First, as in FIG. 5A, the cooking container 100 in which food and drink is placed in the storage space 111 is placed in a microwave oven and cooked. At this time, the lid film 200 is in an unopened state.

Referring to FIG. 5B, the temperature of the food increases as the food is heated. The rise in temperature causes steam to be generated from the contents, and the generated steam raises the pressure inside the main body 110. When the vapor pressure inside the main body 110 rises, the lid film 200 starts to swell.

Referring to FIG. 5C, when the vapor pressure reaches a constant pressure in the main body 110, first, the bonding surface of the lid film 200 of the discharge port 131 arranged at the corner of the main body 110 is peeled and opened. That is, in the lid film 200, the second discharge port 131a of the discharge port 131, which is narrower than the first adhesive surface 121a of the protrusion 121, causes the vapor in the storage space 111 to be discharged while first performing the tearing operation.

In this case, when the vapor pressure of the storage space 111 is high and it is difficult to smoothly discharge the vapor only by the discharge port 131, the auxiliary discharge port 133 provided at the center of the other side of the main body 110 is added. The peeling operation is performed.

As a result, the steam inside the main body 110 is maintained at a constant pressure, and the steam pressure does not drop sharply even after the discharge port 131 is opened, so that the contents can be cooked smoothly.

Although the present invention has been described with reference to specific preferred embodiments, the present invention is not limited to the above-described embodiments, and various modifications are possible without departing from the technical idea of the present invention. It goes without saying that changes and modifications are possible.
