Thus, when the water in the seating groove 150 is consumed and reduced by an exothermic reaction with the heating element, the water accommodated in the surplus space portion 163 flows into the seating groove 150 through the communication groove 162, so that the heating element and the water The exothermic reaction by is maintained constant, so that the food in the inner container 200 can be continuously heated.

Specifically, since the excess space portion 163 in which water is accommodated is formed on both sides of the seating groove 150, the inflow water is distributed and accommodated in the excess space portion 163 on both sides along with the seating groove 150, so that the water is seated. Excessive exothermic reaction due to excessive water in the groove 150 is prevented, and as the water in the seating groove 150 is consumed, the water accommodated in the excess space portion 163 is transferred to the seating groove 150 through the communication groove 162. As water is continuously supplied by flowing, an appropriate exothermic reaction can be continuously maintained.

As shown in FIGS. 8 and 16 , the outer container extension 120 and the inner container extension 220 may each have handles 121 and 221 extending outward from the end side. In addition, the

handles

121 and 221 of the outer container extension 120 and the

handles

121 and 221 of the inner container extension 220 may be disposed offset from each other without overlapping each other.

Therefore, when separating the inner container extension part 220 upward from the outer container extension part 120 in order to inject water into the inflow passage 130, the user uses the

handles

121 and 221 disposed offset from each other to pass through the inflow passage. (130) can be easily opened.

As shown in FIGS. 1, 2, 9 and 10, in the food container of the present invention, the inner container 200 and the lid 300 are formed at one of the joint parts between the inner container 200 and the lid 300. A flow path is formed by the combination of the water vapor in the inner container 200 can be discharged to the outside.

To this end, the lid 300 is a groove formed by a portion of the lid-fitting groove 310 depressed upward, and a passage through which water vapor in the inner container 200 is discharged when the inner container 200 and the lid 300 are combined. A cap protrusion 311 to form may be further provided.

Here, at least one cap protrusion 311 may be formed, and the number of cap protrusions 311 formed may be determined according to a purpose.

As the inner surface of a portion of the lid-fitting groove 310 is depressed upward, the outer surface of a portion of the lid-fitting groove 310 protrudes upward, thereby forming the cap protruding body 311 .

Accordingly, when the lid 300 and the inner container 200 are coupled, the inner surface of a portion of the lid fitting groove 310 is the inner surface of the lid projection 311 and the outer portion of the inner container fitting groove 210. The side surfaces are spaced apart from each other, and accordingly, a secondary discharge hole may be formed as a passage through which water vapor may pass in the space between the inner surface of the lid protrusion 311 and the outer surface of the inner container fitting recess 210 .

This auxiliary discharge hole is connected to the inner space of the inner container 200, and water vapor generated by heating food (food) existing in the inner space of the inner container 200 is discharged to the outside through the auxiliary discharge hole. can

As described above, as the water vapor present in the inner space of the inner container 200 is discharged to the outside of the food container of the present invention through the auxiliary discharge hole, the lid 300 and Separation of the inner container 200 or damage to the lid 300 may be prevented in advance.

As a result, some of the water vapor generated inside the outer container 100 as described above passes through the inner space of the inner discharge unit 240 and then through the inner hole 241 to the inner space of the inner container 200. The water vapor supplied to the inner space of the inner container 200 may be discharged to the outside through the auxiliary discharge hole as described above after heating the food.

The above description of the present invention is for illustrative purposes, and those skilled in the art can understand that it can be easily modified into other specific forms without changing the technical spirit or essential features of the present invention. will be. Therefore, the embodiments described above should be understood as illustrative in all respects and not limiting.
