The above-described structure for coupling the lid receiving portion 140 to the outer container 110 is disclosed in Korean Utility Model Registration No. 20-0342089.

The outer container closure member 160 has an outer container closed body portion 161 having a substantially crooked sectional shape and an outer container sealing blade portion 162 extending outwardly from the outer container closed body portion 161 so as to extend downward have.

The outer container closure member 160 is formed of an elastic material such as silicone rubber.

The outer container closure member 160 is configured such that the outer container closed body portion 161 enters the content airtight member groove portion 122 and the outer container sealing blade portion 162 is downwardly inclined outward, 112).

The lid sealing member 170 has a lid sealing body portion 171 having a substantially crooked sectional shape and a lid sealing wing portion 172 formed to extend downward from the lid sealing body portion 171 so as to be inclined downward.

The lid sealing member 170 is formed of an elastic material such as silicone rubber.

The lid sealing member 170 enters the lid sealing member groove part 135 and the lid sealing wing part 172 is inclined downward to the outside, As shown in Fig.

The safety valve 191 is configured to automatically open when the steam pressure of the outer container 110 exceeds a predetermined value. The safety valve 191 having such a configuration is well known in the art, and a detailed description thereof will be omitted.

The steam discharge valve 192 is configured to open automatically when the steam pressure of the content container 120 and the outer container 110 exceeds a predetermined value. The steam discharge valve 192 having such a configuration is well known in the art, and a detailed description thereof will be omitted.

A method of using a conventional portable cooking vessel having the above-described configuration will be described with reference to FIG. It is assumed that the outer container closure member 160 is provided in the content gas sealing member groove portion 122 and the lid sealing member 170 is provided in the lid sealing member groove portion 135 for convenience of explanation. It is assumed that the content container 120 is installed on the upper side of the outer container 110 so that the lower end of the outer container sealing vane 162 contacts the upper surface of the outer container flange 112.

The lid receiving portion 140 can be installed in the following manner.

The lid support unit 140 is rotated until the aligning protrusion 152b reaches the end of the alignment guide groove 151a in a state where the outer container latching plate 153 is disposed in the space between the outer container latching unit 144 .

When the aligning projection 152b reaches the end of the alignment guide groove 151a, the resting projection 152c enters the restraint groove 151b by the elastic force accumulated in the spring (not shown).

When the restricting projection 152c enters the restricting groove 151b, the lid supporting part 140 is prevented from moving outward, and thus the contact state between the lid sealing member 170 and the content gas sealing member groove part 122 The contact state between the container closing member groove portion 122 and the receiving portion flange 142 and the contact state between the outer container sealing member 160 and the outer container flange 112 are respectively maintained.

When the lid receiving portion 140 is to be separated from the outer container 110, the lid receiving portion 140 is moved in a straight line while the restricting protrusion 152c is moved so as to be disengaged from the restricting groove 151b by operating the operation button 152a. In the opposite direction.

The container lid 130 may be installed in the lid receiving portion 140 in the following manner.

The container lid 130 is rotated so that the lid engaging plate portion 132 enters the lower side of the lid engaging horizontal portion 143b in a state where the lid engaging plate portion 132 is disposed in the space between the lid engaging portions 143. [

The lid sealing member 170 is in contact with the upper surface of the content sealing member groove portion 122 in a state in which the lid engaging plate portion 132 enters the lower side of the lid horizontal surface portion 143b, And contacts the bottom surface of the engaging horizontal surface portion 143b.

When the container lid 130 is installed, the lid supporting part 140 is prevented from moving outward by the support restricting part 150, so that the lid sealing member 170 and the contents gas- The contact state between the upper surfaces and the state in which the capping plate portion 132 enters the lower side of the capping horizontal surface portion 143b is maintained.

Food can be cooked in the following way.

First, the heating element 201 and water are introduced into the bottom surface of the outer container 110 (see FIG. 22).

Heat is generated by the hydration reaction between the heating element 201 and water.

Next, the contents container 120 and the lid receiving portion 140 are installed.

Next, the food to be cooked is placed in the container 120, and then the container lid 130 is installed.

The food is heated by heat transmitted from the heating element 201 to the container 120 in a state where the container lid 130 is installed.

However, according to the conventional portable cooking container, since the lid sealing member groove portion 135 is formed in the container lid 130, the structure of the container lid 130 becomes complicated.

Further, since the lid sealing member 170 is provided in the lid sealing member groove 135, there is a problem in that it is difficult to replace and clean the lid sealing member 170.

Since the lid sealing member 170 is installed so that the lid sealing wing portion 172 is in contact with the upper surface of the content gas sealing member groove portion 122 in a downwardly inclined state outwardly, There is a problem in that it is discharged to the outside of the content container 120 through the space between the wing portion 172 and the upper surface of the content gas sealing member groove portion 122 (see FIG. 23).

A second problem arises that the cooking time is prolonged if the heat is released from the content container 120 to the outside.

Since the outer container sealing member 160 is installed so that the outer container sealing vane 162 contacts the upper surface of the outer container flange 112 in a state where the outer container sealing vane 162 is inclined downward, There is a problem in that the air is discharged to the outside of the outer container 110 through the space between the container sealing vane 162 and the upper surface of the outer container flange 112 (see FIG. 23).

A second problem arises that the cooking time is prolonged if heat is discharged from the heating-element accommodation space 126 to the outside.
