The inner container 200 is a rectangular parallelepiped with only the upper surface open and made of paper or synthetic resin. At this time, dry food is stored in the inner container 200 .

On the other hand, the box body 100 and the inner container 200 may be provided with different types of paper. For example, the box body 100 may be made of paper that can keep the outer appearance of the packaging box well and prevent dry food from getting wet, and the inner container 200 may be used to store the dry food It can be made of paper that can absorb oil that may occur in the case of frying and at the same time minimize the transfer of heat generated from dry food to the outside or lower container.

More specifically, the box body 100 may be corrugated cardboard composed of inner and outer paper and a corrugating medium inserted therebetween. The inner and outer paper may contain at least one polysaccharide component selected from pectin, xanthan gum, and carrageenin. Preferably, at least one component of pectin, xanthan gum, and carrageenin contained in the inner and outer paper may be about 5% to 15% by weight.

The inner and outer papers of the box body 100 prepare a pulp composition containing at least one of pectin, xanthan gum, and carrageenin, and prepare the pulp composition in a paper-based form It can be produced by the step of papermaking and pressing and drying the paper-made paper.

Pulping of the base paper may be performed using various pulping methods that can be used in the manufacture of wood pulp, such as soda pulping, organic solvent pulping, kraft, sulfurous acid, and the like. Subsequently, the pulp composition is made into a paper-based paper, and the paper-made paper is then compressed, dehydrated, and dried to be made into paper.

The porosity of the box body 100 may be 35% to 45%, and the porosity of the inner container 200 may be 15% to 25%. The average pore size of the box body 100 may be 5 um to 10 um, and the average pore size of the inner container 200 may be 0.5 um to 4 um.

In addition, the bottom surface 110 of the box body 100 and a region other than the bottom surface 110 may be configured to have different properties. To this end, the coating agent may be applied only to the front surface 120, the rear surface 130, the left and right side surfaces 150 and 160, and the pair of covers 140 except for the bottom surface 110 of the box body 100.

More specifically, sorbitol, mannitol, xylitol, erythritol, maltitol, and lac 55 to 65% by weight of two or more components of titol, calcium phosphate, titanium dioxide, magnesium phosphate, aluminum hydroxide, aluminum silicate, magnesium silicate, magnesium trisilicate, magnesium aluminum silicate, sodium aluminum silicate, potassium aluminum silicate, calcium aluminum silicate and bentonite 5 to 15% by weight of at least one component selected from acrylic acid cross-linked polymers, acrylamide cross-linked polymers, copolymer polymers in which acrylic acid and acrylamide are weakly cross-linked, starch proppolymers, cross-linked starch derivatives, and cellulose derivatives. A coating agent containing 25 to 35% by weight of at least one component may be applied.

Through this, the bottom surface 110 of the box body 100 can firmly maintain the load of the lower container 300 containing wet food weighed by moisture for a long time, and at the same time, the front 120 and the rear ( 130), the left and right sides 150 and 160, and the pair of covers 140 can more efficiently maintain the humidity and temperature of dry food for a long time. Accordingly, it is possible to maintain the outer appearance of the packaging box well and at the same time prevent the dry type food from getting wet, and furthermore, the oil of the food accommodated in the inner container can be well absorbed.

That is, in the case of the present invention, it is possible to prevent deterioration of food, secure storage stability, and maintain food freshness by promoting packaging optimization reflecting the characteristics of dry and wet food, suppress the elution of harmful substances during packaging, and prevent the release of endocrine disruptors during disposal. It can be prevented, and furthermore, it is possible to secure the convenience of movement by packaging dry and wet foods together.

The lower container 300 is made of paper or synthetic resin with a water-repellent coating on the inside to accommodate moist food, and the open top of the lower container 300 is physically sealed with a lid or sealer that waterproofs the open portion. It may be finished by a sealing film (not shown) that seals the interior waterproofly.

The lower container 300 is installed below the box body 100.

Specifically, an opening 102 is formed on the bottom surface 110 of the box body 100, and a flange 310 engaging the opening 102 is formed in the lower container 300. At this time, the outer diameter of the flange 310 is larger than the inner diameter of the opening 102 to prevent the lower container 300 from being separated from the opening 102 . For example, the outer diameter of the flange 310 is about 20 cm to 22 cm, the inner diameter of the opening 102 is about 18 cm to 20 cm, and the inner diameter of the opening 102 is 85% to 85% of the outer diameter of the flange 310. It can be 95%.

In addition, the opening 102 is formed of one of circular, elliptical, or polygonal shapes, and the lower container 300 is provided in a shape corresponding to the shape of the opening 102 .

Conversely, the cross section of the lower container 300 is formed as one of circular, elliptical, or polygonal, and the opening 102 is opened to correspond to the shape of the lower container 300 .

Meanwhile, the sum of the height of the inner container 200 and the height of the flange 310 may be 95% to 100% of the height of the accommodation space 101 . That is, the sum of the height of the inner container 200 and the height of the flange 310 may be substantially the same as the height of the accommodation space 101.

Accordingly, after the lower container 300 is installed in the opening 102, in a state where the inner container 200 is placed on top of the lower container 300, the inner container 200 is covered by the cover 140 As it is fixed, the inner container 200 and the lower container 300 are prevented from moving.

In other words, the upper wall of the inner container 200 is supported downward by the inner surface of the lid 140, and the bottom surface of the inner container 200 may be supported upward by the upper surface of the flange 310.

In some embodiments, the lower container 300 is configured to be divided into two or more spaces as shown, so that two or more foods (eg, jjajangmyeon and jjamppong) may be stored, but is not limited thereto.

According to the present invention, dry foods such as sweet and sour pork fried meat are stored in the box body 100, and moist foods such as sweet and sour pork sauce are separated in the lower container 300 installed through the bottom of the box body 100. It can be stored and packed, and the lower container 300 can store separate food without invading the storage space 101 of the box body 100, so space utilization is improved. In addition, by separating the box body 100 and the lower container 300, it is possible to prevent food from being mixed.

Those skilled in the art related to the present embodiment will be able to understand that it may be implemented in a modified form within a range that does not deviate from the essential characteristics of the above description. Therefore, the disclosed methods are to be considered in an illustrative rather than a limiting sense. The scope of the present invention is shown in the claims rather than the foregoing description, and all differences within the equivalent scope will be construed as being included in the present invention.
