The reason is that when the diameter of the vapor discharge hole 310 formed while the hole processing part 220 penetrates the cover film 300 is less than 1.0mm, the high pressure vapor generated in the first base body 100 This is because the amount of steam discharged through the steam discharge hole 310 is less than the amount of (steam), so that the cover film 300 swells up and bursts.

In addition, when the diameter of the vapor discharge hole 310 formed while the hole movable part 210 passes through the cover film 300 is formed to exceed 5.0 mm, the high-pressure vapor generated in the first base body 100 (steam ) Is discharged into the steam discharge hole 310 in an instant, the heating effect of the food by the high-temperature steam (steam) is reduced and the texture is degraded.

Preferably, the moisture content of the food in the first container body 100 is large, or in the case of freezing, the diameter of the steam discharge hole 310 is formed to be 3.0 mm to 5.0 mm, and the moisture content of the food is small, In the case of interior, it is most ideal to make the diameter size of the vapor discharge hole 310 as small as 0.1mm to 2.5mm.

Meanwhile, the hole processing unit 220 may be detachably coupled to the first heat-sealing plate 200 by a detachment means 230 as shown in FIG. 2.

Such a detachable means 230 is formed at the lower end of the first heat fusion plate 200 protrudes downward and is formed at the upper end of the bolt part 231 and the hole processing part 220 formed with a thread around the outer periphery. It may be configured to include a bolt fastening groove 232 screwed with the bolt part 231, but is not limited thereto and, on the contrary, the bolt fastening groove 232 is formed at the lower end of the first heat fusion plate 200, and the hole A bolt portion 231 may be formed on the upper end of the processing portion 220.

On the other hand, the first heat-sealing plate 200 and the first base body 100 applied to the present invention are shown to have a rectangular shape, but are not limited thereto, and the heat-sealing plate 200 and the container body 100 are circular or It is preferable that it can be made of a polygon.

In addition, although the hole processing part 220 is shown in the shape of a sharp awl in the drawing, the lower end is not limited thereto, and may be formed in various shapes such as circular, polygonal, and star-shaped.

When the food cooking container 10 manufactured by such a manufacturing method is put into a microwave oven and heated, the internal pressure increases and pressure is applied to the cover film 300 by the expansion pressure of the steam (steam), When the pressure applied to the film 300 is more than a certain pressure (set pressure), the cover film attached to the first flange part 110 close to the inside of the first base body 100 based on the first space part 120 As 300 falls, high-pressure steam (steam) is discharged to the outside through the vapor discharge hole 310 in the upper direction.

That is, the present invention forms a vapor discharge hole 310 through which vapor is discharged from the cover film 300 while heat-sealing the cover film 300 to the first flange portion 110 of the first base body 100 By making the manufacturing process simple, the production efficiency can be increased and the manufacturing cost can be significantly reduced.

In addition, by forming a vapor discharge hole 310 in the cover film 300 so that the vapor is discharged in the upper direction, a vapor discharge hole is formed on the flange surface of the container body so that the vapor is discharged downward. As a result, it is possible to solve the problem that steam was not discharged smoothly.
