## Abstract

Provided is a heating container simply cooks or heats foods using a heater without help of a heating device required for cooking during the outdoor leisure activation such as climbing or fishing. The heating container includes a main body in which a heater is inserted and water is poured, a built-in container inserted into the main body, the built-in container providing a space for cooking foods therein, and a sealing cover sealing an opened upper portion of the built-in container, the sealing cover being coupled to the main body when the built-in container is sealed. Each of the main body and the built-in container is formed of a rigid material, and vapor generated when water within the main body is boiled is discharged between the main body and the built-in container to the outside.

## Claims

### Claim 1

A heating container comprising:
a main body in which a heater is inserted and water is poured;
a built-in container inserted into the main body, the built-in container providing a space for cooking foods therein; and
a sealing cover sealing an opened upper portion of the built-in container, the sealing cover being coupled to the main body when the built-in container is sealed,
wherein each of the main body and the built-in container is formed of a rigid material, and vapor generated when water within the main body is boiled is discharged between the main body and the built-in container to an outside via a gap;
wherein a seat part on which a first upper end of the built-in container is seated is disposed on a first, opened, upper end of the main body;
wherein a hook part hooked on the seat part of the main body to prevent the built-in container from being further inserted into the main body is disposed on a second, opened, upper end of the built-in container; and
wherein the gap between the seat part of the main body and the hook part of the built-in container is about 0.05 mm to about 0.15 mm.

### Claim 2 (depends on 1)

The heating container of claim 1, wherein an attached portion of the sealing cover closely attached to the built-in container is formed of a soft material, and the built-in container and the sealing cover are closed attached to each other.

### Claim 3 (depends on 1)

The heating container of claim 1, wherein a detachable piece for coupling the sealing cover to the main body is disposed on the sealing cover or the main body.

### Claim 4 (depends on 1)

The heating container of claim 1, wherein an exposing groove for exposing the first upper end of the built-in container to the outside is defined in a second upper end of the main body.

### Claim 5 (depends on 1)

The heating container of claim 1, wherein an elastic member for elastically supporting the built-in container with respect to the main body is disposed between an inner bottom surface of the main body and the built-in container, a fixing protrusion in which a lower end of the elastic member is inserted to straighten a position of the elastic member protrudes from the inner bottom surface of the main body.

### Claim 6 (depends on 3)

The heating container of claim 3, further comprising a heat insulator surrounding the main body to prevent heat generated by the heater from being released to the outside through the main body.

### Claim 7 (depends on 3)

The heating container of claim 3, wherein a height between a first bottom surface of the built-in container and a second bottom surface of the main body is about 2 cm to about 5 cm in consideration of a height of the heater.
