The outer cover 14 can protect the thermal insulation panel 11 disposed inside it and prevent tearing due to external factors and can be formed of a tarpaulin material having a waterproof function.

At the same time, all the covers placed on the two side wall portions of the insulating panel 11 , which are placed inside the compartment 160 , can be formed of a silver material or a silver foil material. Since the silver material or the silver foil material has a flexible property when compared with the tarpaulin material, a shape of the compartment 160 can be flexibly deformed inside the accommodating space S.

FIG. 6 is an enlarged view illustrating an end portion of the third sidewall portion 123 . Referring to FIG. 6 , an easy-stick pad may be attached to an inner side of the inner cover 13 and an outer side of the outer cover 14 . For example, the second adhesive member 310b to which the first adhesive member 310a disposed on one surface of the engaging portions 131, 132, 133 and 134 is adhered may be disposed on the inner side of the inner cover 13 and disposed on the folded sheet The second adhesive element 330 b to which the first adhesive element 330 a on one surface of the 141 is adhered may be disposed on the outer side of the outer cover 14 .

For example, the second adhesive element 310b may be disposed on one surface of the second sidewall portion 122 and one surface of the fourth sidewall portion 124 .

7 and 8, after the bottom part 110, the side wall parts 121, 122, 123 and 124 and the engaging parts 131, 132, 133 and 134 are assembled into a box shape, the compartment 160 can be accommodated inside the accommodation space S. Specifically, the compartment 160 may be formed to be connected from an upper end of the third side wall portion 123, and when assembled in a box mode, the compartment 160 may be received in a folded or rolled form relative to the third side wall portion 123 Inside the accommodating space S.

Since the compartment 160 is formed of a flexible material, the compartment 160 may be accommodated inside the accommodating space S in various forms. One of the various accommodation forms of the compartment 160 will be described in detail below with reference to FIGS. 9 to 13 .

FIGS. 9-13 are diagrams taken along line AA' of FIG. 1 showing various states in which the cooling package 100 is used, according to an exemplary embodiment of the present invention.

Referring to FIGS. 9 to 13 , the cooling package 100 may include an accommodation space S. As shown in FIG. In the box mode, the accommodating space S can be understood as a space surrounded by the bottom portion 110 , the side wall portions 121 , 122 , 123 and 124 and the cover 140 .

The accommodating space S may include a refrigerated accommodating space S1 and a general accommodating space S2. The refrigerated accommodating space S1 and the general accommodating space S2 may be separated by a compartment 160 .

A portion of the refrigerated containing space S1 may be surrounded by the compartment 160 . Specifically, in the box mode, the compartment 160 may be accommodated inside the accommodation space S by being folded or rolled inward. The refrigerated accommodating space S1 may be understood as an inner space of the compartment 160 formed such that the compartment 160 is folded or rolled inward.

More specifically, the refrigerated accommodation space S1 may be formed between the compartment 160 , the third side wall portion 123 and the bottom portion 110 . One surface of the compartment 160 may form part of a wall of the refrigerated containment space S1.

Foods or articles that need to be stored at low temperature can be accommodated in the refrigerated accommodating space S1.

The general accommodating space S2 can be understood as a part other than the refrigerating accommodating space S1 of the accommodating space S. FIG. Specifically, the general accommodating space S2 can be understood as an outer space of the compartment 160 when the compartment 160 is folded or rolled inward. More specifically, the general receiving space S2 may be formed between the compartment 160 , the second side wall portion 122 , the cover 140 and the bottom portion 110 . The outer surface of the compartment 160 may form part of a wall of the general containment space S2.

Foods or articles that need to be stored at room temperature can be accommodated in the general accommodating space S2.

Due to the thermal insulation panel 11 disposed inside the compartment 160, the heat loss in the refrigerated accommodation space S1, which occurs so that the heat of the general accommodation space S2 is introduced into the refrigerated accommodation space S1, can be reduced.

The cooling package 100 may contain the refrigerant holding film 170 . A cryogen retention membrane 170 may be attached to the compartment 160 . Specifically, the cryogen retaining film 170 may be attached to a surface of the compartment 160 facing the refrigerated accommodation space S1. That is, the cryogen retaining film 170 may be attached to one surface of the compartment 160 .

The refrigerant holding space S3 may be formed between the compartment 160 and the refrigerant holding film 170 . The refrigerant R can be accommodated in the refrigerant holding space S3. The refrigerant R can lower the temperature of one of the refrigerated storage spaces S1 to make the refrigerated storage space S1 an environment in which refrigerated storage is achieved.

The refrigerant holding space S3 may be divided into a plurality of spaces. For example, as shown in FIGS. 2 and 9 to 14 , the refrigerant holding space S3 may be divided into three spaces. The cryogen holding space S3 may be divided into a plurality of spaces through a method of sewing and coupling a middle portion of the cryogen holding film 170 to the compartment 160 .

Specifically, the refrigerant R can generally be an ice pack. In this case, since the refrigerant R becomes a solid state when it freezes, in order for the compartment 160 to flexibly move inside the accommodating space S in one of the states in which the refrigerant R is accommodated in the refrigerant holding spaces S3, the The refrigerant holding space S3 is divided into a plurality of spaces and the refrigerant R can be divided and accommodated in the plurality of spaces.

Referring to FIGS. 9 to 14 , since the refrigerant holding film 170 is attached to the surface of the compartment 160 facing the refrigerated accommodation space S1 , at least a portion of the refrigerant R may be disposed above the refrigerated accommodation space S1 .

Specifically, since cold air has a density higher than that of warm air, the cold air may have a property of being oriented in a gravitational direction. Therefore, in order to maintain the refrigerated storage space S1 in a low temperature state, the refrigerant R may be placed above the refrigerated storage space S1. This can be accomplished via a structure in which the cryogen retaining membrane 170 is positioned on one surface of the compartment 160 .

However, the present invention is not limited thereto, and the cryogen retaining film 170 may be provided on both of one side and the other side of the compartment 160 . When the refrigerant R is placed on both of one side and the other side of the compartment 160, all the accommodating spaces S partitioned by the compartment 160 are available for freezing. On the other hand, when the refrigerant R is placed on the other surface of the compartment 160, a space formed on the outer side of one of the compartments 160 when the compartment 160 is folded or rolled inward can be used for freezing. As explained above, when the refrigerant retaining film 170 is provided on both of one surface and the other surface of the compartment 160, since the refrigerant R can be selectively installed on one surface and the other surface of the compartment 160 Apparently, the accommodation space S can therefore be used more flexibly.

Various usage examples of the accommodation spaces S divided by the compartments 160 are shown below.

Referring to FIG. 9 , the accommodating space S may be completely formed as a freezing-type accommodating space S1. In this case, an item to be frozen is first accommodated in the accommodating space S, and then the item is covered with the compartment 160 . Since the length of the compartment 160 in the first direction x is formed to be longer than the length of the bottom portion 110 in the first direction x, the remaining portion after the compartment 160 covers the article can be inserted between the article and the first side wall portion 121 in a gap between. As a result, one of the positions of the compartments 160 can be fixed, and an item that needs to be refrigerated storage can be stably accommodated in the refrigerated accommodation space S1.

Referring to FIG. 10 , the accommodating space S may be divided into a freezing-type accommodating space S1 formed on the right side of the one based on FIG. 10 and a general accommodating space S2 formed on the left side based on the one of FIG. 10 . First, the item to be frozen is positioned adjacent to the third side wall portion 123 and then covered with the compartment 160 . In this case, even when the refrigerant R is installed in the two refrigerant holding spaces S3 formed in the portion close to the third side wall portion 123, the freezing performance of the freezing-type accommodating space S1 can be sufficiently achieved.

After the articles are covered with the compartment 160, the remaining space may be the general-purpose accommodating space S2, and articles that can be stored at room temperature may be accommodated in the general-purpose accommodating space S2. In this case, a portion of the compartment 160 away from the third side wall portion 123 may be squeezed due to the items accommodated in the general accommodating space S2. As a result, the compartment 160 can be fixed, and items that need to be refrigerated storage can be stably accommodated in the refrigerated accommodating space S1.

Referring to FIG. 11 , the accommodating space S may be divided into a freezing-type accommodating space S1 formed on a lower side based on FIG. 10 and a general accommodating space S2 formed on an upper side based on FIG. 10 . First, the item to be frozen is placed in an entire area of the bottom portion 110, and then the compartment 160 can be used to cover the item. In this case, a portion of the compartment 160 proximate to the third side wall portion 123 may be adjacent to the third side wall portion 123, and even when the cryogen R rests on the two cryogens formed on the distal side of one of the third side wall portions 123 When the holding space S3 is maintained, the freezing performance of the refrigerating storage space S1 can also be fully achieved.

After the articles are covered with the compartment 160, the remaining space may be the general-purpose accommodating space S2, and articles that can be stored at room temperature may be accommodated in the general-purpose accommodating space S2. In this case, the compartment 160 may be squeezed due to one of the items contained in the general containment space S2. As a result, the compartment 160 can be fixed, and items that need to be refrigerated storage can be stably accommodated in the refrigerated accommodating space S1.

Referring to FIG. 12 , the compartment 160 may be disposed inside the accommodating space S in a state of being rolled inward. In this case, instead of arranging the items to be refrigerated storage inside the accommodating space S first, the compartment 160 can surround the items to be refrigerated, and then the compartment 160 and the items to be refrigerated can be placed at the same time Inside the accommodating space S. This storage method is suitable for the case where the size of the item to be frozen is small, and since the item to be frozen is surrounded by the refrigerant R, the item to be frozen can be effectively frozen and stored.

Referring to FIG. 13 , the accommodating space S may be integrally formed as a general accommodating space S2. In this case, the compartment 160 rests on one of the bottoms of the accommodating spaces S first, and an item capable of being stored at room temperature can be accommodated on the compartment 160 .

As explained above, the compartment 160 is formed of a flexible material and divides the refrigerant holding space S3 into a plurality of spaces, the compartment 160 can be accommodated inside the accommodating space S in various shapes, and the accommodating space S can be accommodated according to the An item is organized by a size and a shape and according to whether the item is frozen and stored.

In particular, even when a single plane has a complex shape, such as forming a cross or a protrusion, a phenomenon such as jamming or hooking can occur during the cleaning procedure. That is, the unfolded form of a complex shape can be a hindrance to implementing cleaning automation.

For example, in the unfolded mode, when the engaging portions 131 , 132 , 133 and 134 are not provided in the cooling package 100 and thus a gap occurs between the plurality of side wall portions 121 , 122 , 123 and 124 , in the In one procedure of putting the cooling package 100 in the cleaning device M, the second side wall portion 122 and the third side wall portion 123 may serve as protruding portions, and the cleaning procedure may not be performed smoothly.

As explained above, in the cooling packaging box 100 according to an exemplary embodiment of the present invention, the engaging portions 131 , 132 , 133 and 134 for connecting the adjacent side wall portions 121 , 122 , 123 and 124 are provided such that The shape of the cooling package 100 in the unfolded mode can be simplified, and the cleaning process can be performed smoothly.

In addition, the outer side edges of the engaging portions 131, 132, 133 and 134 may be formed to be rounded. That is, in general, the sidewall portions 121, 122, 123, and 124 connected based on the bottom portion 110 and the joint portions 131, 132, 133, and 134 connected between the sidewall portions 121, 122, 123, and 124 may each be formed as A quadrilateral shape whose vertex is a circle. As a result, when the cooling package 100 is put into the cleaning device M, the cooling package 100 can be smoothly put into the cleaning device M without a stuck portion, and the cleaning procedure can be performed smoothly.
