[0052] By providing the bottom portion (110), side portions (121, 122, 123, 124), joint portions (131, 132, 133, 134), and cover portion (140) to be connected as described above, it is easy to switch from unfolded mode to box mode, and in box mode, a receiving space (S) capable of holding food, etc. inside can be easily provided.

[0053] Referring to FIG. 1, the insulated packaging box (100) may include a handle (142). The handle (142) may be formed on the outer surface of the cover portion (140). The handle (142) may be manufactured separately from the cover portion (140) and attached to the cover portion (140). In this case, the handle (142) may be attached to the cover portion (140) by sewing or by using an adhesive. Alternatively, the handle (142) may be formed integrally with the cover portion (140).

[0054] The handle (142) is positioned in the central area of ​​the cover portion (140), so that when a user grasps and lifts the box mode insulated packaging box (100), the supporting force is applied evenly to the insulated packaging box (100) so that no tilting occurs.

[0055] The insulated packaging box (100) may include a label (143). The label (143) may include a barcode label containing shipping information.

[0056] The label (143) may be placed on the outer surface of the side portions (121, 122, 123, 124) or the cover portion (140). Preferably, the label (143) may be placed on the outer surface of the cover portion (140). This allows delivery information to be easily verified through a barcode reader, etc., when the insulated packaging box (100) is delivered in box mode.

[0057] Referring to FIGS. 1 and FIGS. 3, the label (143) may be provided separately at a location different from the invoice receiving pad (150), but alternatively, the label (143) may be provided so as to be included inside the invoice receiving pad (150).

[0058] Referring to FIGS. 2 and 3, the insulated packaging box (100) may include a partition (160). The partition (160) may be formed to be connected to any one of a plurality of side sections (121, 122, 123, 124). The partition (160) may extend from the side opposite to the side adjacent to the bottom section (110) among the four sides of the side sections (121, 122, 123, 124).

[0059] Preferably, the partition portion (160) may be connected to a side portion (123) positioned on the other side of the first direction (x) of the bottom portion (110) among a plurality of side portions (121, 122, 123, 124). That is, the partition portion (160) may be connected to a third side portion (123) which is a side portion opposite to the first side portion (121) to which the cover portion (140) is connected. In this way, if the cover portion (140) and the partition portion (160) are formed to be connected at side portions facing each other, the phenomenon of interference between the cover portion (140) and the partition portion (160) can be minimized when assembled in box mode.

[0060] Alternatively, the partition (160) may be formed in a shape that protrudes and extends inwardly from the inner surface of the side portions (121, 122, 123, 124) according to the partitioning intention of the receiving space (S).

[0061] Referring to FIGS. 2 and 3, the partition (160) can be folded or rolled inward toward the receiving space (S) to partition the receiving space (S) when the insulated packaging box (100) is converted into a box mode.

[0062] The partition (160) can be formed of a flexible material. Accordingly, the partition (160) can bend freely inside the receiving space (S) and partition the receiving space (S) into various shapes. The method of partitioning the receiving space (S) will be explained in detail later in relation to FIGS. 9 to 13.

[0063] The second direction (y) length of the partition part (160) may be formed to be equal to or smaller than the second direction (y) length of the bottom part (110). That is, the width of the partition part (160) may be equal to or smaller than the width of the bottom part (110). Through this, the partition part (160) can be easily folded or rolled inward into the receiving space (S) in box mode. In addition, each part can be easily folded without interference with each other in handheld mode. Details regarding the handheld mode will be described later in relation to FIGS. 15 to 17.

[0064] The first direction (x) length of the partition portion (160) may correspond to the sum of the first direction (x) length of the bottom portion (110) and the first direction (x) length of the first side portion (121) or the third side portion (123). Through this, when an item is received in the refrigerated receiving space (S1) formed inside the insulated packaging box (100), the partition portion (160) can organically respond to various receiving forms of the refrigerated item. Details related to this will be explained in detail later in relation to FIGS. 9 to 13.

[0065] In contrast, the first direction (x) length of the partition section (160) may be formed to be larger or smaller than the sum of the first direction (x) length of the bottom section (110) and the first direction (x) length of the first side section (121) or the third side section (123). That is, the first direction (x) length of the partition section (160) may be formed to various lengths as needed.

[0066] The insulated packaging box (100) may include a refrigerant receiving membrane (170). The refrigerant receiving membrane (170) may be attached to a partition (160). Details regarding the specific attachment location of the refrigerant receiving membrane (170) will be described in detail later in relation to FIGS. 9 to 14.

[0067] The refrigerant receiving membrane (170) can be attached to the partition (160) by sewing. At this time, the sewing line (173) extends in the second direction (y) and can be arranged in the first direction (x).

[0068] Specifically, referring to FIG. 2, one side and the other side of the first direction (x) of the refrigerant receiving membrane (170) can be sewn and joined to the partition (160). That is, a sewing line (173) can be formed on each side and the other side of the first direction (x) of the refrigerant receiving membrane (170).

[0069] Additionally, the middle portion of the refrigerant receiving membrane (170) can be sewn and joined to the partition portion (160). For example, as shown in FIG. 2, a seam (173) extending in a second direction (y) can be formed in the middle portion of the refrigerant receiving membrane (170). Through this, the refrigerant receiving space (S3) formed between the partition portion (160) and the refrigerant receiving membrane (170) can be divided into multiple sections.

[0070] This is not limited thereto, and depending on the shape of the planned refrigerant receiving space (S3), the seam (173) may be extended in the first direction (x) or formed in a curved shape, and depending on the size and number of the planned refrigerant receiving space (S3), the number and position of the seam (173) may vary.

[0071] The refrigerant receiving space (S3) may be opened in at least one of the second direction (y) and the other direction. Through this open portion, the refrigerant (R) can be received between the refrigerant receiving membrane (170) and the partition (160).

[0072] Specifically, referring to FIG. 2, the refrigerant receiving membrane (170) is sewn only in the horizontal direction, so the left and right sides of the refrigerant receiving membrane (170) can be opened. Since both the left and right sides of the refrigerant receiving membrane (170) are open, the refrigerant (R) can be easily received between the partition (160) and the refrigerant receiving membrane (170), regardless of whether the user is right-handed or left-handed.

[0073] The refrigerant receiving membrane (170) may include a mesh portion (171). By providing a mesh portion (171) formed of a mesh material in the refrigerant receiving membrane (170), when the refrigerant (R) is received between the refrigerant receiving membrane (170) and the partition portion (160), the cold air of the refrigerant (R) can easily penetrate the refrigerant receiving membrane (170), thereby improving the refrigeration efficiency of the refrigeration receiving space (S1).

[0074] The refrigerant receiving membrane (170) may include an elastic portion (172). The elastic portion (172) may be, for example, made of a rubber band material. The elastic portion (172) may be extended in a first direction (x) and positioned on one side and the other side edge of the second direction of the mesh portion (171). That is, referring to FIG. 2, an elastic portion (172) extending in a vertical direction may be positioned on the left and right sides of the refrigerant receiving membrane (170).

[0075] Specifically, the elastic member (172) can prevent the partition member (160) from being separated from the left side and / or right side of the refrigerant receiving membrane (170) and the partition member (160) when the partition member (160) is folded or rolled up and received into the receiving space (S). By doing so, the elastic member (172) can prevent the refrigerant (R) from escaping between the open side of the refrigerant receiving membrane (170) and the partition member (160) when the partition member (160) is folded or rolled up.

[0076] A specific example of use in which the refrigerant (R) is received in the refrigerant receiving space (S3) will be explained in detail later in relation to FIGS. 9 to 13.

[0077] Referring to FIGS. 1 to 3, the insulated packaging box (100) may include an invoice receiving pad (150). The invoice receiving pad (150) may be placed on the outer surface of the cover portion (140). An invoice may be received between the invoice receiving pad (150) and the cover portion (140).

[0078] The invoice receiving pad (150) may include a display portion (151). The display portion (151) may be formed of a transparent material. For example, the display portion (151) may be formed of a transparent vinyl material. When an invoice is received between the invoice receiving pad (150) and the cover portion (140), information on the invoice can be checked through the transparent display portion (151).

[0079] The invoice receiving pad (150) may include a border portion (152). The border portion (152) may be formed on a portion of the edge of the display portion (151). For example, the display portion (151) may be formed in a square shape, and the border portion (152) may be formed on only three sides of the edge of the display portion (151). Through the portion where the border portion (152) is not formed, the invoice receiving pad (150) can be attached to the cover portion (140), and the invoice can be received between the invoice receiving pad (150) and the cover portion (140).

[0080] Referring to FIG. 1, the insulated packaging box (100) may include an adhesive reinforcement part (153). The invoice receiving pad (150) may have its adhesive strength to the cover part (140) reinforced through the adhesive reinforcement part (153). The adhesive reinforcement part (153) may be formed by stitching. Specifically, the adhesive reinforcement part (153) may be formed by stitching the portion adjacent to the four corners of the invoice receiving pad (150) to the cover part (140) after the invoice receiving pad (150) is attached to the cover part (140) by a simple adhesive pad (350).

[0081] The adhesive reinforcement (153) can prevent the invoice receiving pad (150) from detaching from the cover (140). Specifically, when transporting the insulated packaging box (100), a problem may occur where the invoice receiving pad (150) gets caught by external factors and detaches from the cover (140). Since the adhesive reinforcement (153) performs the role of reinforcing the adhesion of the invoice receiving pad (150) once more, the invoice receiving pad (150) can be prevented from easily detaching from the cover (140) through the adhesive reinforcement (153).

[0082] The adhesive reinforcement (153) should be formed so that the invoice receiving pad (150) can be torn off from the cover (140) when the invoice receiving pad (150) is replaced. Accordingly, it may be preferable for the adhesive reinforcement (153) to be formed only in a portion of the edge of the invoice receiving pad (150) adjacent to the four vertices of the invoice receiving pad (150).

[0083] In contrast, if the adhesive strength of the simple adhesive pad (350) is sufficiently strong, the adhesive reinforcement (153) may not be provided. Additionally, the adhesive reinforcement (153) may be formed in a manner other than stitching. Furthermore, if the strength of the thread used for stitching is weak, the adhesive reinforcement (153) may be formed by extending along the edge portion (152) of the invoice receiving pad (150).

[0084] The edge portion (152) may be formed of the same material as the outer surface of the insulated packaging box (100). For example, the edge portion (152) may be made of tarpaulin material. Through this, the durability of the edge portion of the invoice receiving pad (150) can be reinforced, and the problem of the display portion (151) tearing when the invoice receiving pad (150) is attached or detached can be prevented.

[0085] The invoice receiving pad (150) can be attached to the outer surface of the cover portion (140) by means of a simple adhesive pad (350) formed along the edge. The structure in which the invoice receiving pad (150) is attached to the cover portion (140) by means of the simple adhesive pad (350) will be described in detail later.

[0086] The insulated packaging box (100) may include a simple adhesive pad (310, 320, 330, 340, 350). The simple adhesive pad (310, 320, 330, 340, 350) may refer to a member of a competitive method that allows for repeated adhesion and separation. The simple adhesive pad (310, 320, 330, 340, 350) may include a bonding method in which adhesion and separation occur when surfaces meet. For example, the simple adhesive pad (310, 320, 330, 340, 350) may be Velcro tape.

[0087] The simple adhesive pad (310, 320, 330, 340, 350) may include a first adhesive element (310a, 320a, 330a, 340a, 350a) and a second adhesive element (310b, 320b, 330b, 340b, 350b). The first adhesive element (310a, 320a, 330a, 340a, 350a) and the second adhesive element (310b, 320b, 330b, 340b, 350b) may be bonded to each other in box mode. For example, either one of the first adhesive element (310a, 320a, 330a, 340a, 350a) and the second adhesive element (310b, 320b, 330b, 340b, 350b) may be formed with hook-shaped microstructures, and the other may be formed with loop-shaped microstructures.

[0088] Referring to FIGS. 2 and 3, the simple adhesive pads (310, 320, 340) may be provided on the side portions (121, 122, 123, 124) and the joint portions (131, 132, 133, 134).

[0089] For example, referring to FIG. 2, a first adhesive element (310a) may be provided on one side of the first joint (131) and / or on one side of the second joint (132), and a second adhesive element (310b) may be provided on one side of the first side part (121). The first adhesive element (310a) placed on one side of the first joint (131) and / or on one side of the second joint (132) may be adhered to the second adhesive element (310b) placed on one side of the first side part (121) when converted to box mode.

[0090] Additionally, a first adhesive element (310a) may be provided on one side of the third joint (133) and / or one side of the fourth joint (134), and a second adhesive element (310b) may be provided on one side of the third side portion (123). The first adhesive element (310a) disposed on one side of the third joint (133) and / or one side of the fourth joint (134) may be adhered to the second adhesive element (310b) disposed on one side of the third side portion (123) when converted to box mode.

[0091] Additionally, a first adhesive element or a second adhesive element (340b) may be provided on one side of the second side portion (122) and / or on one side of the fourth side portion (124). For example, a second adhesive element (340b) may be provided on one side of the second side portion (122) and / or on one side of the fourth side portion (124). If an auxiliary partition portion (not shown) is provided, a first adhesive element (340a, not shown) provided on the auxiliary partition portion (160) may be attached to a second adhesive element (340b) provided on one side of the second side portion (122) and / or on one side of the fourth side portion (124).

[0092] Additionally, referring to FIG. 3, a first adhesive element (320a) and a second adhesive element (320b) may be provided on the other side of the joint portions (131, 132, 133, 134). In each joint portion (131, 132, 133, 134), the first adhesive element (320a) and the second adhesive element (320b) may be positioned symmetrically to each other with respect to the fold line (410) and formed in a symmetrically shaped form. When assembled in box mode, each joint (131, 132, 133, 134) is folded inward along the fold line (410), and the first adhesive element (320a) and the second adhesive element (320b) provided on the other side of the joint (131, 132, 133, 134) are attached to each other, thereby maintaining the folded state of the joint (131, 132, 133, 134).

[0093] In this way, the box shape can be maintained when the insulated packaging box (100) is converted into a box mode through the simple adhesive pad (320) provided on the side portions (121, 122, 123, 124) and the joint portions (131, 132, 133, 134).

[0094] Additionally, referring to FIGS. 2 and 3, a simple adhesive pad (330) may be provided on one side of the wing portion (141) and on the other side of the second side portion (122), the third side portion (123), and the fourth side portion (124).

[0095] For example, a first adhesive element (330a) may be provided on one side of the wing portion (141), and a second adhesive element (330b) may be provided on the other side of the second side portion (122), the third side portion (123), and the fourth side portion (124). When assembled in box mode, after the cover portion (140) covers the upper surface of the receiving space (S) formed by the bottom portion (110) and the side portions (121, 122, 123, 124), the wing portion (141) is folded downward, and the first adhesive element (330a) provided on the wing portion (141) may be adhered to the second adhesive element (330b) provided on the other side of the second side portion (122), the third side portion (123), and the fourth side portion (124). Through this, the cover portion (140) can be fixed to the side portions (121, 122, 123, 124).

[0096] Additionally, referring to FIGS. 2 and 3, a simple adhesive pad (350) may be provided on the cover portion (140) and the invoice receiving pad (150) to secure the invoice receiving pad (150) to the cover portion (140).

[0097] For example, a first adhesive element (350a) may be provided on one side of the invoice receiving pad (150), and a second adhesive element (350b) may be provided on the other side of the cover portion (140) at the location where the invoice receiving pad (150) is placed. Through this, the invoice receiving pad (150) can be attached to and detached from the cover portion (140).

[0098] Specifically, if a transport worker accidentally attaches a shipping label that is attached by a sticker method onto the shipping label receiving pad (150), it may not be easy to remove only the shipping label. In this case, if the shipping label receiving pad (150) is not designed to be detachable, a problem may occur where the cover part (140) is torn together during the process of removing the sticker-type shipping label from the shipping label receiving pad (150). As described above, if the shipping label receiving pad (150) is provided with a structure that allows for detachment by a simple adhesive pad (350), the shipping label receiving pad (150) can be easily replaced, thereby preventing such problems and allowing the insulated packaging box (100) to be used for a long time.

[0099] The first adhesive element (350a) provided on one side of the invoice receiving pad (150) may be formed on only three of the four sides of the display portion (151). That is, the first adhesive element (350a) may be provided on the edge portion (152) within the range where the edge portion (152) is formed. In addition, the second adhesive element (350b) provided on the outer surface of the cover portion (140) may be formed to correspond to the position and shape of the first adhesive element (350a) provided on the invoice receiving pad (150).

[0100] Through this, when the invoice receiving pad (150) is attached to the cover portion (140), at least one side can be opened, and the invoice can be received between the invoice receiving pad (150) and the cover portion (140) through the opened side.

[0101] Referring to FIGS. 2 and 3, in the unfolded mode, the first adhesive element (310a, 330a) provided on one side of the side portion (121, 122, 123, 124), joint portion (131, 132, 133, 134), and wing portion (141) may be positioned so as not to overlap with the second adhesive element (320b, 330b, 350b) provided on the other side of the side portion (121, 122, 123, 124), joint portion (131, 132, 133, 134), and cover portion (140). Additionally, the second adhesive element (310b, 340b) provided on one side of the side portions (121, 122, 123, 124) and the joint portions (131, 132, 133, 134) may be positioned so as not to overlap with the first adhesive element (320a) provided on the other side of the side portions (121, 122, 123, 124) and the joint portions (131, 132, 133, 134). That is, the first adhesive element (310a, 330a) provided on one side of the insulated packaging box (100) may not overlap with the second adhesive element (320b, 330b, 350b) placed on the other side, and the second adhesive element (310b, 340b) provided on the other side of the insulated packaging box (100) may not overlap with the first adhesive element (320a) placed on the other side.

[0102] Specifically, a plurality of insulated packaging boxes (100) can be stored overlapping each other while unfolded in an unfolded state. At this time, if the first adhesive element (310a, 330a) provided on one side of any one insulated packaging box (100) and the second adhesive element (320b, 330b, 350b) provided on the other side of the adjacent insulated packaging box (100) do not overlap each other, and if the second adhesive element (310b, 340b) provided on one side of any one insulated packaging box (100) and the first adhesive element (320a) provided on the other side of the adjacent insulated packaging box (100) do not overlap each other, the phenomenon of the adjacent insulated packaging boxes (100) sticking together can be prevented, and any one of the plurality of insulated packaging boxes (100) can be easily removed.

[0103] Referring to FIG. 3, a first adhesive element (320a) and a second adhesive element (320b) attached to joints (131, 132, 133, 134) can be formed symmetrically to each other in two regions of joints (131, 132, 133, 134) that are divided as the joints (131, 132, 133, 134) are folded. At this time, the first adhesive element (320a) and the second adhesive element (320b) can be formed to a maximum size within a range where they do not overlap each other in the unfolded mode. For example, the first adhesive element (320a) and the second adhesive element (320b) can be formed in a strip shape having a certain thickness, and the first adhesive element (320a) and the second adhesive element (320b) can be formed to a maximum thickness within a range where they do not overlap each other in the unfolded mode.

[0104] Specifically, the insulation panel (11, see FIG. 4) is provided only on the bottom portion (110), the side portions (121, 122, 123, 124), and the cover portion (140), and may not be provided on the joint portions (131, 132, 133, 134) for ease of assembly. Therefore, to improve the insulation performance of the cold storage packaging box (100), it may be desirable to minimize the gap between the multiple side portions (121, 122, 123, 124) in box mode. At this time, if the joint portions (131, 132, 133, 134) are well maintained in a folded state, the gap between each side portion (121, 122, 123, 124) and the adjacent side portions (121, 122, 123, 124) can be minimized when assembled in box mode. To achieve this, it may be desirable to strengthen the adhesive force of the simple adhesive pad (320) provided on the other side of the joint (131, 132, 133, 134).

[0105] More specifically, referring to FIG. 3, the first joint (131) can be divided into an upper triangular area and a lower triangular area based on a diagonal fold line (410). At this time, the first adhesive element (320a) can be formed in a strip shape extending in the first direction (x) of the upper triangular area, and the second adhesive element (320b) can be formed in a strip shape extending in the second direction (y) of the lower triangular area. When the first adhesive element (320a) and the second adhesive element (320b) are formed with maximum thickness while being symmetrical with respect to the fold line (410), the left side of the first adhesive element (320a) is adjacent to the right side of the first side part (121), the bottom side of the second adhesive element (320b) is adjacent to the top side of the second side part (122), and the bottom right vertex of the first adhesive element (320a) and the top left vertex of the second adhesive element (320b) may be in contact with or adjacent to each other.

[0106] These features may be applied equally to the second joint (132), the third joint (133), and the fourth joint (134). However, not limited thereto, the simple adhesive pad (320) provided on the other side of the joints (131, 132, 133, 134) may be formed in various sizes and shapes (see embodiment of FIG. 20), and each joint (131, 132, 133, 134) may be provided with a simple adhesive pad (320) of a different size and shape.

[0107] FIG. 4 is an enlarged cross-sectional view illustrating the unfolded state of a folded portion of a cold storage packaging box according to one embodiment of the present disclosure. FIG. 5 is an enlarged cross-sectional view illustrating the folded state of a folded portion of a cold storage packaging box according to one embodiment of the present disclosure. FIG. 6 is an enlarged cross-sectional view illustrating the end of a side portion of a cold storage packaging box according to one embodiment of the present disclosure.

[0108] Referring to FIGS. 4 to 6, the insulated packaging box (100) may include an insulating panel (11). The insulating panel (11) may be placed on the side portions (121, 122, 123, 124) and on the inside of the bottom portion (110). The insulating panel (11) may be formed from a material capable of having insulating performance while maintaining a plate shape. For example, the insulating panel may be formed from expanded polypropylene (EPE) or foam board. Not limited thereto, the insulating panel (11) may be formed from various materials having insulating performance.

[0109] Referring to FIG. 4, the insulation panel (11) provided on the inner side of the bottom portion (110) may be formed with a thicker thickness than the insulation panel (11) provided on the inner side of the side portions (121, 122, 123, 124). Since the bottom portion (110) is a part that comes into contact with the floor while receiving the load of the goods contained in the receiving space (S) of the insulated packaging box (100), the insulation panel (11) of the bottom portion (110) may receive more impact and may easily become thinner than the insulation panel (11) of the side portions (121, 122, 123, 124). Therefore, in order to maintain the insulation performance of the bottom portion (110), it may be preferable that the thickness of the insulation panel (11) provided on the bottom portion (110) is greater than the thickness of the insulation panel (11) provided on the side portions (121, 122, 123, 124). For example, the insulation panel (11) provided on the bottom portion (110) may have a thickness of 18T, and the insulation panel (11) provided on the side portions (121, 122, 123, 124) may have a thickness of 12T. Not limited thereto, the insulation panel (11) may be formed with various thicknesses depending on the size of the insulated packaging box (100) and the required insulation performance.

[0110] Furthermore, the insulation panel (11) may also be placed on the inner side of the cover portion (140). The insulation panel (11) placed on the cover portion (140) can improve the insulation performance of the upper surface of the insulated packaging box (100) in box mode. The structure in which the insulation panel (11) is placed on the cover portion (140) can be understood as the same as the structure in which the insulation panel (11) is placed on the bottom portion (110).

[0111] Additionally, the insulation panel (11) may also be placed on the inner side of the partition (160). Since the partition (160) is placed so that it can be flexibly bent on the inner side of the accommodation space (S), the insulation panel (11) placed on the inner side of the partition (160) may be formed with a thinner thickness than the insulation panel (11) placed on the inner side of the bottom part (110) and / or the side part (121, 122, 123, 124). For example, the insulation panel (11) placed on the inner side of the partition (160) may be formed with a thickness of 3T. The insulation panel (11) placed on the partition (160) may serve to prevent heat loss between the refrigerated accommodation space (S1) and the general accommodation space (S2).

[0112] The insulated packaging box (100) may include a support panel (12). The support panel (12) may be placed on the inner side of the side portions (121, 122, 123, 124). The support panel (12) may be placed on the inner side of the insulation panel (11) on the inner side of the side portions (121, 122, 123, 124), but is not limited thereto and may also be placed on the outer side of the insulation panel (11).

[0113] The support panel (12) can serve to reinforce the structure of the side sections (121, 122, 123, 124) when the side sections (121, 122, 123, 124) are set up in box mode. That is, the support panel (12) can be formed from a material that is harder than the insulation panel (11). For example, the support panel (12) can be a PVC (polyvinyl chloride) panel. It is not limited thereto, and the support panel (12) can be formed from various materials such as metal or wood.

[0114] The insulated packaging box (100) may include an inner cover (13) and an outer cover (14). An insulating panel (11) and / or a support panel (12) may be placed between the inner cover (13) and the outer cover (14). The inner cover (13) may be formed of silver or silver foil material for insulation or cooling. The outer cover (14) may be formed of tarpaulin material that protects the insulating panel (11) placed on the inside, prevents tearing due to external factors, and has a waterproof function.

[0115] Meanwhile, the covers placed on both sides of the insulation panel (11) placed on the inner side of the partition (160) can all be formed of silver or silver foil material. Since silver or silver foil material has flexible physical properties compared to tarpaulin material, the partition (160) can flexibly change shape on the inner side of the receiving space (S).

[0116] FIG. 6 is an enlarged view of the end of the third side portion (123). Referring to this, a simple adhesive pad can be attached to the inner side of the inner cover (13) and the outer side of the outer cover (14). For example, a second adhesive element (310b) to which a first adhesive element (310a) provided on one side of the joint portion (131, 132, 133, 134) is attached may be provided on the inner side of the inner cover (13), and a second adhesive element (330b) to which a first adhesive element (330a) provided on one side of the wing portion (141) is attached may be provided on the outer side of the outer cover (14).

[0117] The insulated packaging box (100) may include a folding portion (400). The folding portion (400) may be formed between the bottom portion (110) and the side portions (121, 122, 123, 124). Referring to FIGS. 5 and 6, the folding portion (400) may include a groove having a certain spacing distance (D1). The portion of the folding portion (400) where the groove is formed may not have an insulating panel (11) inside and may be composed only of an inner cover (13) and an outer cover (14). The thickness (D2) of the portion of the folding portion (400) where the groove is formed may be formed to be smaller than the thickness (D3, D4) of the portion containing the insulating panel (11) inside.

[0118] If the insulation panel (11) is not formed on the folding portion (400), the side portions (121, 122, 123, 124) can be easily erected from the bottom portion (110) during the process of converting to box mode. The cover portion (140) can also be easily folded from the first side portion (121).

[0119] Additionally, if a groove is formed in the folding portion (400), the contamination of the folding portion (400) can be effectively removed when the device is converted to an unfolded mode and cleaning is performed. Specifically, in box mode, some of the stored food may flow out and contaminate the bottom portion (110), and in particular, contaminants may become fixed on the folding portion (400) located at the edge of the bottom portion (110) and may not be easily removed even when placed in a cleaning device. At this time, if a groove is formed in the folding portion (400), a small gap can be secured even when the side portions (121, 122, 123, 124) are standing upright against the bottom portion (110), and even if contaminants enter, they may not become fixed and can be easily removed by the cleaning device.

[0120] FIGS. 7 and 8 are perspective views illustrating the process of assembling a cooling packaging box according to one embodiment of the present disclosure from unfolded mode to box mode.

[0121] FIG. 7 illustrates the step in which the insulated packaging box (100) begins to fold in unfolded mode, and FIG. 8 illustrates the state before the cover part (140) covers the side parts (121, 122, 123, 124) of the insulated packaging box (100) are erected against the bottom part (110) and the partition part (160) is received inside the receiving space (S).

[0122] Referring to FIGS. 7 and FIGS. 8 together with FIGS. 1 to 3, the insulated packaging box (100) can be mutually converted from an unfolded state (see FIG. 2) to a box mode (see FIG. 1) in which a receiving space (S) for storing food, etc. is formed inside.

[0123] Referring to FIGS. 2 and 3, the bottom portion (110) and the side portions (121, 122, 123, 124) are formed to unfold into a single plane in unfolded mode. The bottom portion (110) forms the bottom portion of the cuboid in box mode, and the side portions (121, 122, 123, 124) form the side portions of the cuboid in box mode.

[0124] In box mode, adjacent sides of each side portion (121, 122, 123, 124) that meet each other may separate from each other in unfolded mode, and a gap may occur. A joint portion (131, 132, 133, 134) may be formed in this gap portion.

[0125] The side sections (121, 122, 123, 124) connected to the bottom section (110) and the joint section (131, 132, 133, 134) connecting the side sections (121, 122, 123, 124) can be formed in an overall roughly square shape.

[0126] For example, the first side portion (121) and the second side portion (122) may include adjacent sides that meet each other in box mode, and as the device is converted to unfolded mode, the adjacent sides may spread apart from each other, and a first joint portion (131) may be formed to connect the adjacent sides that are thus separated. That is, the first joint portion (131) may form a single plane together with the first side portion (121) and the second side portion (122) in unfolded mode.

[0127] In this manner, the second joint (132), the third joint (133), and the fourth joint (134) can each form a plane with an adjacent side section. Through this, when the insulated packaging box (100) is converted to an unfolded mode and inserted into a washing device, a shape can be formed that allows for complete washing and minimizes factors hindering washing automation. The advantages of the present disclosure regarding the washing device will be explained further later.

[0128] Meanwhile, the edges of the joints (131, 132, 133, 134) may be formed in a rounded shape. For example, the first joint (131) may be formed to connect with the first side portion (121) and the second side portion (122), while the edge portion excluding this may be formed in a curved shape. In this way, the second joint (132), the third joint (133), and the fourth joint (134) may each be formed to connect with adjacent side portions, while the edge portion excluding this may be formed in a curved shape.

[0129] Accordingly, the side portions (121, 122, 123, 124) connected around the bottom portion (110) and the joint portions (131, 132, 133, 134) connecting the side portions (121, 122, 123, 124) can be formed in a square shape with rounded vertices overall. Through this, the user can easily handle the insulated packaging box (100) in unfolded mode, and since sharp parts that could get caught in the washing device when inserted into the washing device are removed, washing automation can proceed more smoothly.

[0130] Referring to FIG. 7, as the unfolded mode is converted to a box mode, the joints (131, 132, 133, 134) can be folded. The joints (131, 132, 133, 134) can maintain a physical connection with adjacent side parts even when converted to a box mode.

[0131] In box mode, the parts where adjacent sides of each side (121, 122, 123, 124) meet each other may be vulnerable to heat loss due to heat leakage or heat inflow (hereinafter collectively referred to as 'heat loss'). At this time, if the joint (131, 132, 133, 134) is provided to be connected to the side (121, 122, 123, 124), such heat loss can be effectively prevented.

[0132] Referring to FIG. 7, when converted to box mode, the multiple side sections (121, 122, 123, 124) that were unfolded are erected, and the adjacent sides of each side section (121, 122, 123, 124) can be brought closer together. At this time, each joint section (131, 132, 133, 134) connected to the adjacent side can be folded inward so as to overlap themselves along a folding line (410) that extends diagonally from the vertex of the bottom section (110).

[0133] A simple adhesive pad (320) may be provided on the outer surface, i.e., the other surface, of the joint (131, 132, 133, 134). Specifically, a first adhesive element (320a) and a second adhesive element (320b) may be provided in each of the two areas formed by folding the joint (131, 132, 133, 134), and when the joint (131, 132, 133, 134) is folded, the first adhesive element (320a) and the second adhesive element (320b) may be bonded to each other. Through this, the joint (131, 132, 133, 134) can maintain a folded state.

[0134] Referring to FIGS. 7 and 8, the folded joints (131, 132, 133, 134) can be bonded to the inside of the fully vertically erected side sections (121, 122, 123, 124) through a simple adhesive pad (310).

[0135] Specifically, the first joint (131) and the fourth joint (134) can be attached to the inner surface of the first side portion (121). At this time, the first adhesive element (310a) provided adjacent to the upper surface of one side of the first joint (131) and the first adhesive element (310a) provided adjacent to the upper surface of one side of the fourth joint (134) can be attached to the second adhesive element (310b) provided on the upper surface of one side of the first side portion (121).

[0136] Additionally, the second joint (132) and the third joint (133) may be attached to the inner surface of the third side portion (123). At this time, the first adhesive element (310a) provided adjacent to the upper surface of one side of the second joint (132) and the first adhesive element (310a) provided on the upper surface of one side of the third joint (133) may be attached to the second adhesive element (310b) provided on the upper surface of one side of the third side portion (123).

[0137] Unlike as illustrated in FIGS. 7 and 8, the folded first joint (131) and second joint (132) may be attached to one side of the second side (122), and the third joint (133) and fourth joint (134) may be attached to one side of the fourth side (124). In this case, a second adhesive element (310b) may be provided on one side of the second side (122) and on one side of the fourth side (124).

[0138] Referring to FIGS. 7 and 8, after the bottom portion (110), side portions (121, 122, 123, 124), and joint portions (131, 132, 133, 134) are assembled in a box shape, a partition portion (160) can be accommodated inside the receiving space (S). Specifically, the partition portion (160) can be formed to extend from the top of the third side portion (123), and when assembled in a box mode, it can be accommodated inside the receiving space (S) in a form that is folded or rolled inward relative to the third side portion (123).

[0139] Since the partition part (160) is formed of a flexible material, it can be accommodated in various forms inside the accommodation space (S). Details regarding the various accommodation forms of the partition part (160) will be explained in detail later in relation to FIGS. 9 to 13.

[0140] FIGS. 9 to 13 illustrate the AA' cross-sectional view of FIG. 1 and illustrate various usage states of a cold storage packaging box according to one embodiment of the present disclosure.

[0141] Referring to FIGS. 9 through 13, the insulated packaging box (100) may include a receiving space (S). The receiving space (S) can be understood as a space enclosed by the bottom portion (110), side portions (121, 122, 123, 124), and lid portion (140) in box mode.

[0142] The storage space (S) may include a refrigerated storage space (S1) and a general storage space (S2). The refrigerated storage space (S1) and the general storage space (S2) may be partitioned by a partition (160).

[0143] The refrigerated receiving space (S1) may be a portion enclosed by a partition (160). Specifically, in box mode, the partition (160) may be folded or rolled inward to be received within the receiving space (S). The refrigerated receiving space (S1) may be understood as the inner space of the partition (160) formed by the partition (160) being folded or rolled inward.

[0144] More specifically, the refrigerated storage space (S1) may be formed between the partition section (160), the third side section (123), and the bottom section (110). One side of the partition section (160) may form part of the wall of the refrigerated storage space (S1).

[0145] Food or items requiring low-temperature storage can be accommodated in the refrigerated storage space (S1).

[0146] The general accommodation space (S2) can be understood as the portion of the accommodation space (S) other than the refrigerated accommodation space (S1). Specifically, the general accommodation space (S2) can be understood as the outer space of the partition section (160) when the partition section (160) is folded inward or rolled up. More specifically, the general accommodation space (S2) can be formed between the partition section (160), the second side section (122), the cover section (140), and the bottom section (110). The other side of the partition section (160) can form part of the wall of the general accommodation space (S2).

[0147] Food or items that can be stored at room temperature can be accommodated in the general accommodation space (S2).

[0148] Heat loss in the refrigerated space (S1) caused by heat from the general space (S2) flowing into the refrigerated space (S1) can be reduced by the insulation panel (11) placed on the inner side of the partition (160).

[0149] The insulated packaging box (100) may include a refrigerant receiving membrane (170). The refrigerant receiving membrane (170) may be attached to a partition section (160). Specifically, the refrigerant receiving membrane (170) may be attached to the side of the partition section (160) facing the refrigerated receiving space (S1). That is, the refrigerant receiving membrane (170) may be attached to one side of the partition section (160).

[0150] A refrigerant receiving space (S3) may be formed between the partition (160) and the refrigerant receiving membrane (170). A refrigerant (R) may be received inside the refrigerant receiving space (S3). The refrigerant (R) lowers the temperature of the refrigeration receiving space (S1), thereby creating an environment in which the refrigeration receiving space (S1) can be refrigerated.

[0151] The refrigerant receiving space (S3) may be divided into multiple spaces. For example, as shown in FIGS. 2 and FIGS. 9 through 14, the refrigerant receiving space (S3) may be divided into three spaces. The refrigerant receiving space (S3) may be divided into multiple spaces by sewing the middle portion of the refrigerant receiving membrane (170) to the partition portion (160).

[0152] Specifically, the refrigerant (R) can generally be an ice pack. In this case, since the refrigerant (R) is in a solid state when frozen, in order for the partition part (160) to move flexibly inside the refrigerant receiving space (S3) while the refrigerant (R) is contained in the refrigerant receiving space (S3), it may be desirable to divide the refrigerant receiving space (S3) into multiple sections and divide and contain the refrigerant (R) in each space.

[0153] Referring to FIGS. 9 to 14, since the refrigerant receiving membrane (170) is attached to the side of the partition (160) facing the refrigeration receiving space (S1), at least a portion of the refrigerant (R) can be placed above the refrigeration receiving space (S1).

[0154] Specifically, since cold air has a higher density than warm air, it may have the property of moving in the direction of gravity. Therefore, in order to maintain the refrigeration space (S1) in a low-temperature state, it may be desirable for the refrigerant (R) to be placed at the top of the refrigeration space (S1). This purpose can be achieved through a structure in which the refrigerant receiving membrane (170) is placed on one side of the partition (160).

[0155] However, not limited thereto, the refrigerant receiving membrane (170) may be provided on both one side and the other side of the partition section (160). When the refrigerant (R) is placed on both one side and the other side of the partition section (160), the entire receiving space (S) partitioned by the partition section (160) can be used for refrigeration. On the other hand, when the refrigerant (R) is placed only on the other side of the partition section (160), the space formed on the outside of the partition section (160) when the partition section (160) is folded inward or rolled up may be used for refrigeration. In this way, when the refrigerant receiving membrane (170) is provided on both one side and the other side of the partition section (160), the refrigerant (R) can be selectively installed on both the one side and the other side of the partition section (160), allowing the receiving space (S) to be used more flexibly.

[0156] Various examples of use in which the receiving space (S) is divided by a partition (160) are as follows.

[0157] Referring to FIG. 9, the entire receiving space (S) can be formed as a refrigerated receiving space (S1). In this case, items requiring refrigerated storage can be placed in the receiving space (S) first, and then covered with a partition (160). Since the length of the first direction (x) of the partition (160) is formed to be longer than the length of the first direction (x) of the bottom part (110), the remaining portion of the partition (160) after covering the items can be inserted into the gap between the items and the first side part (121). Through this, the position of the partition (160) can be fixed, and items requiring refrigerated storage can be stably received in the refrigerated receiving space (S1).

[0158] Referring to FIG. 10, the receiving space (S) can be divided into a refrigerated receiving space (S1) formed on the right side and a general receiving space (S2) formed on the left side. First, items requiring refrigeration can be placed adjacent to the third side section (123), and then the partition section (160) can be covered. At this time, even if refrigerant (R) is installed only in the two refrigerant receiving spaces (S3) formed near the third side section (123), the refrigeration performance of the refrigerated receiving space (S1) can be sufficiently achieved.

[0159] After covering the items with the partition (160), the remaining space may be a general storage space (S2), and items that can be stored at room temperature may be stored in the general storage space (S2). At this time, the part of the partition (160) that is far from the third side (123) may be pressed down by the items stored in the general storage space (S2). Through this, the partition (160) can be fixed, and items that need to be refrigerated can be stably stored in the refrigerated storage space (S1).

[0160] Referring to FIG. 11, based on FIG. 10, the receiving space (S) can be divided into a refrigerated receiving space (S1) formed at the bottom and a general receiving space (S2) formed at the top. First, items requiring refrigeration can be placed across the entire area of ​​the bottom portion (110), and then the partition portion (160) can be covered. At this time, the part of the partition portion (160) that is close to the third side portion (123) can be adjacent to the third side portion (123), and even if the refrigerant (R) is installed only in the two refrigerant receiving spaces (S3) formed far from the third side portion (123), the refrigeration performance of the refrigerated receiving space (S1) can be sufficiently achieved.

[0161] After covering the items with the partition (160), the remaining space may be a general storage space (S2), and items that can be stored at room temperature may be stored in the general storage space (S2). At this time, the partition (160) may be pressed by the items stored in the general storage space (S2). Through this, the partition (160) can be fixed, and items that need to be refrigerated can be stably stored in the refrigerated storage space (S1).

[0162] Referring to FIG. 12, the partition (160) can be placed inside the receiving space (S) in a rolled-in state. In this case, instead of placing the refrigerated item inside the receiving space (S) first, the refrigerated item can be wrapped with the partition (160), and then the partition (160) and the refrigerated item can be placed inside the receiving space (S) simultaneously. This receiving method may be suitable when the size of the refrigerated item is not large, and since the refrigerated item is surrounded by a refrigerant (R), the refrigerated item can be effectively refrigerated.

[0163] Referring to FIG. 13, the entire receiving space (S) can be formed as a general receiving space (S2). In this case, the partition (160) can first be laid on the floor of the receiving space (S), and then items that can be stored at room temperature can be placed on top of it.

[0164] In this way, the partition (160) is formed of a flexible material, and as the refrigerant receiving space (S3) is divided into multiple sections, the partition (160) can be received in various shapes inside the receiving space (S), and the receiving space (S) can be organically divided according to the size, shape, and whether the item to be received is refrigerated.

[0165] FIG. 14 illustrates a cooling packaging box according to one embodiment of the present disclosure being washed in an unfolded mode.

[0166] Referring to FIG. 14, the insulated packaging box (100) can be unfolded into a single plane in unfolding mode, and the unfolded insulated packaging box (100) can be fed into a washing device (M) and automatically washed.

[0167] The washing device (M) may be provided so that one side and the other side of the insulated packaging box (100) are automatically washed as the insulated packaging box (100) in the unfolded mode passes through in a certain direction.

[0168] The cleaning process can be performed more easily and completely as the shape of the unfolded cooling packaging box (100) becomes simpler, such as a square. Specifically, even if it is a single flat surface, if its shape is complex, such as a cross shape, or if protrusions are formed, phenomena such as jamming or catching may occur during the cleaning process. In other words, a complex unfolded shape can be an obstacle to implementing cleaning automation.

[0169] For example, in the unfolded mode, the joints (131, 132, 133, 134) are not provided in the insulated packaging box (100), so the gap between the multiple side parts (121, 122, 123, 124) widens. In the process of being inserted into the washing device (M), the second side part (122) and the third side part (123) may act as protruding parts, and the washing process may not be performed smoothly.

[0170] As such, the insulated packaging box (100) according to one embodiment of the present disclosure is provided with a joint (131, 132, 133, 134) connecting adjacent side portions (121, 122, 123, 124), so that the shape of the insulated packaging box (100) in unfolded mode can be simplified and the cleaning process can be performed smoothly.

[0171] Additionally, the outer edges of the joints (131, 132, 133, 134) may be formed in a rounded shape. That is, the joints (131, 132, 133, 134) connecting the side portions (121, 122, 123, 124) connected to the bottom portion (110) may have a square shape with rounded vertices overall. Through this, when the insulated packaging box (100) is inserted into the washing device (M), it can be inserted into the washing device (M) smoothly without any obstruction, and the washing process can be performed smoothly.

[0172] FIGS. 15 to 17 are perspective views illustrating a method of converting a cooling packaging box according to one embodiment of the present disclosure from an unfolded mode to a portable mode.

[0173] Referring to FIGS. 15 to 17, a cold storage packaging box (100) according to one embodiment of the present disclosure can be converted from an unfolded mode to a portable mode. The portable mode can be understood as a mode in which the volume and size of the cold storage packaging box (100) are minimized. By converting to a portable mode, when the cold storage packaging box (100) is returned to a delivery company after delivery is completed and the contents are removed, the return can be carried out efficiently.

[0174] The following describes the process of converting from deployment mode to handheld mode.

[0175] Referring to FIG. 15, in unfolded mode, the partition portion (160) of the insulated packaging box (100) can be folded inward. At this time, since the second direction (y) length of the partition portion (160) is equal to or smaller than the second direction (y) length of the bottom portion (110), the first side portion (121), or the second side portion (122), when the partition portion (160) is folded inward, it can be positioned within the formation range of the bottom portion (110), the second side portion (122), and the third side portion (123).

[0176] Specifically, as illustrated in FIG. 15, if the first direction (x) length of the partition (160) is formed to be equal to or smaller than the sum of the first direction (x) lengths of the bottom part (110) and the third side part (123), the partition (160) may overlap with the bottom part (110) and the third side part (123).

[0177] Unlike what is shown in FIG. 15, if the first direction (x) length of the partition (160) is formed to be greater than the sum of the first direction (x) lengths of the bottom part (110) and the third side part (123), the partition (160) may also overlap with at least a part of the first side part (121).

[0178] Referring to FIG. 16, after the partition (160) is folded inward, the first side portion (121), the first joint portion (131), and the second joint portion (132) positioned on one side of the partition (160) can be folded inward. Additionally, the third side portion (123), the third joint portion (133), and the fourth joint portion (134) positioned on the other side of the partition (160) can be folded inward.

[0179] At this time, since the second direction (y) length of the partition part (160) is formed to be smaller than the second direction (y) length of the bottom part (110), when the two sides of the partition part (160) are folded inward, they can be folded smoothly without interference from the partition part (160).

[0180] Next, the third side portion (123) and the second joint portion (132) superimposed thereon, and the third joint portion (133) can be folded inward. In this process, the second adhesive element (330b) placed on the other side of the third side portion (123) can be exposed to the outside. Additionally, the second adhesive element (330b) of the simple adhesive pad (330) placed on the other side of the third side portion (123) can be placed in a position that overlaps with the first adhesive element (330a) of the wing portion (141) placed on one side of the first direction (x) of the cover portion (140) when the cover portion (140) is folded to the other side of the first direction (x) as shown in FIG. 17.

[0181] Referring to FIG. 17, after the third side portion (123) is folded to one side in the first direction (x), the cover portion (140) can be folded inward. At this time, the first adhesive element (330a) of the wing portion (141) positioned on one side in the first direction (x) of the cover portion (140) can be attached to the second adhesive element (330b) positioned on the other side of the third side portion (123). Through this, the insulated packaging box (100) can be fixed in a portable mode state.

[0182] After assembly is completed in portable mode, the wing portions (141) positioned on both sides of the cover portion (140) can be naturally folded downward. Additionally, since the handle (142) positioned on the outer side of the cover portion (140) is exposed to the outside, the user can easily move it by gripping it.

[0183] FIGS. 18 and 19 are perspective views illustrating another method in which a cooling packaging box according to one embodiment of the present disclosure is converted from unfolded mode to portable mode.

[0184] Referring to FIG. 18, unlike the above description in relation to FIG. 15 to 17, before the partition part (160) is folded, the first side part (121) positioned on one side of the bottom part (110), the first joint part (131), and the second joint part (132) can be folded inward. Additionally, before the partition part (160) is folded, the third side part (123), the third joint part (133), and the fourth joint part (134) positioned on the other side of the bottom part (110) can be folded inward.

[0185] Next, the third side portion (123) and the second joint portion (132) superimposed thereon, and the third joint portion (133) can be folded inward. At the same time, the partition portion (160) extending to the other side of the first direction (x) of the third side portion (123) can also be folded inward.

[0186] At this time, since the sum of the first direction (x) length of the partition part (160) in the unfolded state and the first direction (x) length of the third side part (123) is greater than the sum of the first direction (x) length of the first side part (121) and the first direction (x) length of the bottom part (110), a portion of the end of the partition part (160) can be folded. The end of the partition part (160) may be folded inward, or, as shown in FIG. 18, may be folded outward.

[0187] Referring to FIG. 19, when the third side section (123) and the partition section (160) are folded, the second side section (122), the first joint section (131), the second joint section (132), the fourth side section (124), the third joint section (133), and the fourth joint section (134) can be covered by the third side section (123) and the partition section (160).

[0188] Then, when the cover portion (140) is covered, it can be assembled in the same form as shown in FIG. 17. At this time, the method of fixing the cover portion (140) to the third side portion (123) by the simple adhesive pad (330) may be as described above in relation to FIG. 17.

[0189] FIG. 20 is an external unfolded view of a cold storage packaging box according to another embodiment of the present disclosure.

[0190] The detailed configuration of a cold storage packaging box (100) according to another embodiment of the present disclosure that is not described below may be understood to be the same as the detailed configuration of a cold storage packaging box (100) according to one embodiment of the present disclosure described in relation to FIGS. 1 to 19.

[0191] The insulated packaging box (100) may include a simple adhesive pad (320). The simple adhesive pad (320) may be attached to the seams (131, 132, 133, 134). The simple adhesive pad (320) may allow the box shape to be maintained when the insulated packaging box (100) is converted into a box mode.

[0192] The first adhesive element (320a) and the second adhesive element (320b) may be formed symmetrically with respect to each other in two regions of the joint (131, 132, 133, 134) that are divided as the joint (131, 132, 133, 134) is folded. At this time, the first adhesive element (320a) and the second adhesive element (320b) may be formed in a shape and size corresponding to the shape of the two regions of the joint (131, 132, 133, 134) that are divided as the joint (131, 132, 133, 134) is folded.

[0193] Specifically, the joints (131, 132, 133, 134) can be divided into two regions having a shape substantially similar to a triangle based on the fold line (410) that is folded during assembly. At this time, the first adhesive element (320a) and the second adhesive element (320b) can be formed in each of the two regions and can be formed in a triangular shape corresponding to the shape of the two regions.

[0194] The first adhesive element (320a) and the second adhesive element (320b) may be formed to be the same size as the two regions of the joint (131, 132, 133, 134), or may be formed to be slightly smaller than the size of the two regions for ease of folding of the joint (131, 132, 133, 134).

[0195] In this way, the simple adhesive pad (320) is formed with a shape corresponding to the shape of the two regions of the joint (131, 132, 133, 134) divided by the fold line (410) and a size corresponding to the size of the two regions, so that the joint (131, 132, 133, 134) can be strongly bonded in assembly mode. Through this, the gap that may be formed between the plurality of side parts (121, 122, 123, 124) that become adjacent to each other in assembly mode can be minimized, and heat loss that may occur in such gap can be minimized.

[0196] Some or other embodiments of this specification described above are not exclusive or distinct from one another. Some or other embodiments of this specification described above may be used in combination or combined, with their respective configurations or functions.

[0197] For example, this means that configuration A described in a specific embodiment and / or drawing and configuration B described in another embodiment and / or drawing can be combined. That is, it means that even if the combination between configurations is not directly described, combination is possible except in cases where it is described that combination is impossible.

[0198] The foregoing detailed description should not be interpreted restrictively in all respects and should be considered exemplary. The scope of this specification shall be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of this specification are included within the scope of this specification.
