The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Throughout the specification, when a part is said to "include" a certain component, it means that it can further include other components, without excluding other components unless specifically stated otherwise.

In order to clearly illustrate the present invention in the drawings, thicknesses are enlarged in order to clearly illustrate various layers and regions, and parts not related to the description are omitted, and like parts are denoted by similar reference numerals throughout the specification .

Whenever a portion of a layer, film, region, plate, or the like is referred to as being "on" another portion, it includes not only the case where it is "directly on" another portion, but also the case where there is another portion in between. Conversely, when a part is "directly over" another part, it means that there is no other part in the middle.

Hereinafter, with reference to the accompanying drawings will be described a portable heating container according to an embodiment of the present invention.

1 is a perspective view showing a state when carrying the container portion of the portable heating container according to an embodiment of the present invention, Figure 2 is a perspective view showing a state when cooking food of the container portion of FIG.

Referring to FIG. 1, the portable heating container 10 according to the present embodiment includes a container part 100 having a plate shape when being carried. At this time, the groove portion 130 is formed in the container portion 100, by using the groove portion 130 to fold the container portion 100 to have a three-dimensional shape having an internal space where the food is located. More specifically, the container portion 100 may include a central portion 110 positioned at the center portion and side portions 120 positioned at both edges thereof. The groove 130 may be formed at the boundary between the central portion 110 and the side portion 120.

At this time, the side portion 120 may be located at both edges in the long axis direction of the container portion 100, and may be formed to include shorter edges 121 and 122. More specifically, the groove 130 located at the boundary between the central portion 110 and the side portion 120 may have a curved shape connecting both edges of the short edges 121 and 122. Then, the side portion 120 is folded toward the center portion 110 with respect to the groove portion 130 so that the short axis edges 121 and 122 and the long axis edges 123 and 124 are positioned upwards, as shown in FIG. 2. It may have a container shape having an internal space.

The groove 130 will be described in more detail with reference to FIGS. 3A to 3E. 3A is a cross-sectional view taken along line III-III of FIG. 1. 3B to 3E are cross-sectional views of the groove 130 according to the modification.

Referring to FIG. 3A, the groove 130 may have a concave shape 132 at the lower surface thereof while having a concave shape 131 at the upper surface of the container 100. In this case, the depth of the concave shape 131 is the same as the thickness of the convex shape 132, so that the thickness in the groove 130 may have a thickness substantially the same as the central portion 110 and the side portion 120. Alternatively, referring to FIG. 3B, the depth of the concave shape 131 is greater than the thickness of the convex shape 132 so that the thickness in the groove 130 may be relatively smaller than the center portion 110 and the side portion 120. Contrary to FIG. 3B, the depth of the concave form 131 is smaller than the thickness of the convex form 132, as shown in FIG. 3C, so that the thickness in the groove 130 may be relatively greater than the central portion 110 and the side portion 120. .

For example, the ratio T2 / T1 of the thickness T2 of the portion where the groove 130 is formed to the thickness T1 in the portion where the groove 130 is not formed may be 0.05 to 3. If the ratio is less than 0.05, the mechanical properties of the container part 100 in the groove 130 may be degraded, causing problems such as tearing of the container part 100. When the ratio exceeds 3, it may be difficult to fold the container part 100 using the groove part 130.

And the line width of the groove 130 may be 0.3 ~ 30mm. If the line width is less than 0.3mm, it may be difficult to fold the container portion 100 using the groove portion 130. If the line width exceeds 30mm, the groove portion 130 may occupy an unnecessarily large area.

In FIGS. 3A to 3C, a concave shape 131 and a convex shape 132 are provided in a single groove portion 130 so that a cross-sectional shape of the groove portion 130 has a semicircular shape or an inverted shape of an om symbol.
