In this case, the second adhesive element 310b may be provided on one surface of the second side part 122 and one surface of the fourth side part 124 .

7 and 8, after the bottom part 110, the side parts 121, 122, 123, 124 and the joints 131, 132, 133, 134 are assembled in a box shape, the partition part 160 It may be accommodated inside the accommodation space (S). Specifically, the partition portion 160 may be formed to continue from the upper end of the third side portion 123, and when assembled in a box mode, the accommodation space (S) is folded or rolled inward with respect to the third side portion 123. ) can be accommodated inside.

Since the partition part 160 is formed of a flexible material, it can be accommodated in various forms inside the accommodation space (S). Contents related to the various accommodation forms of the partition unit 160 will be described in detail later in relation to FIGS. 9 to 13 .

9 to 13 show a cut A-A' of FIG. 1, and show various states of use of the cold packaging box according to an embodiment of the present disclosure.

Referring to Figures 9 to 13, the cold packaging box 100 may include a receiving space (S). The accommodation space S may be understood as a space surrounded by the bottom part 110, the side parts 121, 122, 123 and 124, and the cover part 140 in the box mode.

The accommodating space (S) may include a refrigerated accommodating space (S1) and a general accommodating space (S2). The refrigerated accommodation space S1 and the general accommodation space S2 may be partitioned by the partition unit 160 .

Refrigerated storage space (S1) may be a portion surrounded by the partition portion (160). Specifically, in the box mode, the partition unit 160 may be accommodated by being folded or rolled into the accommodation space S. The refrigerated storage space S1 may be understood as an inner space of the partition 160 formed by folding or rolling the partition 160 inward.

More specifically, the refrigerated storage space (S1) may be formed between the partition portion 160, the third side portion 123, and the bottom portion 110. One surface of the partition unit 160 may form a part of the wall of the refrigerated storage space S1.

Food or articles requiring low temperature storage may be accommodated in the refrigerated storage space S1.

The general accommodating space (S2) may be understood as a portion other than the refrigerated accommodating space (S1) of the accommodating space (S). Specifically, the general accommodating space S2 may be understood as an outer space of the partition unit 160 when the partition unit 160 is folded or rolled inward. More specifically, the general accommodation space (S2) may be formed between the partition portion 160, the second side portion 122, the cover portion 140, and the bottom portion 110. The other surface of the partition unit 160 may form a part of the wall of the general accommodation space S2.

Food or articles that can be stored at room temperature may be accommodated in the general accommodation space S2.

Heat loss in the refrigerated storage space S1 generated when heat from the general accommodation space S2 flows into the refrigerated storage space S1 can be reduced by the heat insulation panel 11 disposed inside the partition unit 160. .

The cold packaging box 100 may include a refrigerant accommodating film 170 . The refrigerant accommodating film 170 may be attached to the partition unit 160 . Specifically, the refrigerant accommodating film 170 may be attached to a surface of the partition unit 160 facing the refrigerating accommodating space S1. That is, the refrigerant accommodating film 170 may be attached to one surface of the partition unit 160 .

A refrigerant accommodating space S3 may be formed between the partition 160 and the refrigerant accommodating membrane 170 . The refrigerant R may be accommodated inside the refrigerant accommodating space S3. The refrigerant R lowers the temperature of the refrigerated storage space S1 to make the refrigerated storage space S1 into an environment capable of being refrigerated.

The refrigerant accommodating space (S3) may be partitioned into a plurality of spaces. For example, as shown in FIGS. 2 and 9 to 14 , the refrigerant accommodating space S3 may be divided into three spaces. The refrigerant accommodating space S3 may be partitioned into a plurality of spaces by sewing the middle portion of the refrigerant accommodating film 170 to the partition 160 .

Specifically, the refrigerant R may generally be an ice pack. At this time, since the refrigerant R is in a hard state in a frozen state, in order for the partition 160 to move flexibly inside the accommodating space S with the refrigerant R accommodated in the refrigerant accommodating space S3, It may be preferable to divide the refrigerant accommodating space (S3) into a plurality and accommodate the refrigerant (R) separately in each space.

9 to 14, since the refrigerant accommodating film 170 is attached to the surface of the partition 160 facing the refrigerated accommodating space S1, at least a portion of the refrigerant R is transferred to the refrigerated accommodating space S1. can be placed on top of

Specifically, since cold air has a higher density than warm air, it may have a property directed in the direction of gravity. Therefore, in order to maintain the refrigerated storage space S1 at a low temperature, the refrigerant R may be disposed above the refrigerated storage space S1. This objective can be achieved through a structure in which the refrigerant accommodating film 170 is disposed on one surface of the partition unit 160 .

However, it is not limited thereto, and the refrigerant accommodating membrane 170 may be provided on both one side and the other side of the partition unit 160 . When the refrigerant R is disposed on both one side and the other side of the partition unit 160, all of the accommodation spaces S partitioned by the partition unit 160 may be used for refrigeration. Meanwhile, when the refrigerant R is disposed only on the other surface of the partition unit 160, the space formed outside the partition unit 160 when the partition unit 160 is folded or rolled inward may be used for refrigeration. As such, when the refrigerant accommodating membrane 170 is provided on both one side and the other side of the partition unit 160, since the refrigerant R can be selectively installed on one side and the other side of the partition unit 160, the receiving space (S ) can be used more flexibly.

Various use examples in which the accommodation space (S) is divided by the partition unit 160 are as follows.

Referring to FIG. 9 , all of the accommodating spaces S may be formed as refrigerated accommodating spaces S1. In this case, after first accommodating an article requiring refrigerated storage in the accommodating space S, the article may be covered with the partition 160 . Since the length of the partition part 160 in the first direction (x) is longer than the length of the bottom part 110 in the first direction (x), the remaining part after the partition part 160 covers the article is the article and the first side part. It can be inserted into the gap between (121). Through this, the position of the partition unit 160 can be fixed, and the refrigerated storage product can be stably accommodated in the refrigerated storage space S1.

Referring to FIG. 10 , the accommodating space S may be divided into a refrigerated accommodating space S1 formed on the right side and a general accommodating space S2 formed on the left side. First, items requiring refrigeration may be disposed adjacent to the third side portion 123 and then the partition portion 160 may be covered. At this time, even if the refrigerant R is installed only in the two refrigerant accommodating spaces S3 formed near the third side portion 123, the refrigerating performance of the refrigerating accommodating space S1 can be sufficiently achieved.

The remaining space after covering the article with the partition 160 may be a general accommodating space S2 , and articles that can be stored at room temperature may be accommodated in the general accommodating space S2 . At this time, a part far from the third side part 123 of the partition part 160 may be pressed by the goods accommodated in the general accommodating space S2. Through this, the partition unit 160 can be fixed, and the refrigerated storage items can be stably accommodated in the refrigerated storage space S1.

Referring to FIG. 11 , the accommodating space S may be divided into a refrigerated accommodating space S1 formed below and a general accommodating space S2 formed above. First, items requiring refrigeration may be disposed over the entire area of the bottom part 110, and then the partition part 160 may be covered. At this time, the part close to the third side part 123 of the partition part 160 may be adjacent to the third side part 123, and the two refrigerant accommodating spaces S3 formed on the far side of the third side part 123 Even if only the refrigerant R is installed, the refrigerating performance of the refrigerating accommodation space S1 can be sufficiently achieved.

The remaining space after covering the article with the partition 160 may be a general accommodating space S2 , and articles that can be stored at room temperature may be accommodated in the general accommodating space S2 . At this time, the partition part 160 may be pressed by an article accommodated in the general accommodating space S2. Through this, the partition unit 160 can be fixed, and the refrigerated storage items can be stably accommodated in the refrigerated storage space S1.

Referring to FIG. 12 , the partition unit 160 may be disposed inside the accommodation space S while being rolled inward. In this case, instead of first disposing the refrigerated storage items inside the accommodating space (S), after wrapping the refrigerated storage items with the partition portion 160, the partition unit 160 and the refrigerated storage items are simultaneously placed in the accommodating space (S). can be placed inside the This housing method may be suitable when the size of the refrigerated storage item is not large, and since the refrigerant storage item is surrounded by the refrigerant (R), the refrigerated storage item can be effectively refrigerated.

Referring to FIG. 13, all of the accommodating spaces S may be formed as general accommodating spaces S2. In this case, after the partition unit 160 is first laid on the floor of the accommodation space S, items that can be stored at room temperature can be accommodated thereon.

In this way, the partition part 160 is formed of a flexible material, and as the refrigerant accommodating space S3 is divided into a plurality, the partition part 160 can be accommodated inside the accommodating space S in various shapes, The accommodation space S may be organically partitioned according to the size, shape, and refrigeration of the accommodated items.

14 illustrates a state in which an insulated packaging box according to an embodiment of the present disclosure is washed in a deployment mode.
