Description

TECHNICAL FIELD

[0001] The present disclosure relates to a packaging cooling box. BACKGROUND

[0002] Recently, online businesses have rapidly grown, leading to a great increase in food delivery. For food delivery, as with any other conventional delivery, a packaging box is used. As the food delivered gradually diversifies, the demand for delivery of food that needs to be kept refrigerated for a long time increases. In this case, in order to deliver such refrigerated food, the packaging box needs to have a heat insulating member attached thereto, exponentially increasing the waste of packaging resources. In addition, even with the heat insulating member attached to the packaging box, the food often deteriorates upon receipt due to an incomplete cooling function. Therefore, there is an increasing need for a packaging box that can replace a disposable packaging box and has an enhanced cooling function. SUMMARY

[0046] In the following description, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings, enabling those skilled in the art to readily implement the disclosure. The present disclosure may be implemented in many different forms and is not limited to the embodiments described herein.

[0047] In the following description, exemplary embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0048] Figure 1 This is a perspective view of a packaging cooling box according to an embodiment of the present disclosure; Figure 2 This is an internal view of a template used for packaging cooling boxes; and Figure 3 This is an exterior view of a template used for packaging cooling boxes.

[0049] Referring to the above figures, the packaging cooling box 10 of the present invention includes: a first sidewall portion 110, a second sidewall portion 120, a third sidewall portion 130, and a fourth sidewall portion 140; a bottom portion 150, which is formed to connect with the sidewall portions 110, 120, 130, and 140 and forms the lower surface of the packaging cooling box 10 when assembled into a box; and a lid portion 160, which is formed to connect with the fourth sidewall portion 140 and forms the upper surface of the packaging cooling box 10 when assembled into a box. When assembled into a box, the lid portion 160 faces the bottom portion 150.

[0050] The first sidewall portion 110 is configured to face the third sidewall portion 130 when assembled into a box, and the second sidewall portion 120 is configured to face the fourth sidewall portion 140 connected to the cover portion 160 when assembled into a box. Furthermore, the second sidewall portion 120 is configured to be adjacent to the first sidewall portion 110 and the third sidewall portion 130 when assembled into a box. The fourth sidewall portion 140 is configured to be adjacent to the first sidewall portion 110 and the third sidewall portion 130 when assembled into a box.

[0051] Because the side wall portions 110, 120, 130, 140, the bottom portion 150, and the lid portion 160 are configured to connect in this manner, it is easier to convert the packaged cooling box from an unfolded mode to a box mode. In the box mode, space can be provided to hold food.

[0052] The cover portion 160 can further have flaps 161, 162, 163. The flaps 161, 162, 163 can be formed to continue along the remaining side edges of the cover portion 160 except for the side edge connected with the fourth side wall portion 140. The easy-adhesion portion 300 can be provided on at least one of the flaps 161, 162, 163. The arrangement and shape of the easy-adhesion portion 300 will be described in detail below.

[0053] A joint portion 200 is provided between the side wall portions 110, 120, 130, 140. The joint portion 200 is provided between any two adjacent side wall portions among the above-described side wall portions. The joint portion 200 can be configured to be connected with any two adjacent side wall portions among the above-described side wall portions in the unfolded mode. The joint portion 200 can be configured to be integrally connected with adjacent side edges constituting two adjacent side wall portions among the above-described side wall portions in the unfolded mode.

[0054] Specifically, the first joint portion 210 can be configured to be integrally connected with the adjacent side edges included in the first side wall portion 110 and the fourth side wall portion 140, respectively. The second joint portion 220 can be configured to be integrally connected with the adjacent side edges included in the first side wall portion 110 and the second side wall portion 120, respectively. The third joint portion 230 can be configured to be integrally connected with the adjacent side edges included in the third side wall portion 130 and the second side wall portion 120, respectively. Also, the fourth joint portion 240 can be formed to be integrally connected with the adjacent side edges constituting the third side wall portion 130 and the fourth side wall portion 140, respectively.

[0055] The specific structure and function of the joint portion 200 will be described in detail below.

[0056] Reference Figure 2 The crease portion 400 can be provided at a place where the bottom portion 150 meets the side wall portions 110, 120, 130, 140 of the packaging cooling box 10 of the present disclosure.

[0057] The first crease portion 410 can be provided at a place where the bottom portion 150 meets the first side wall portion 110 or the third side wall portion 130. The second crease portion 420 can be provided at a place where the bottom portion 150 meets the second side wall portion 120 or the fourth side wall portion 140. The first crease portion 410 and the second crease portion 420 can be formed to be connected with each other around the edge of the bottom portion 150.

[0058] The third crease portion 430 can be provided at a place where the cover portion 160 meets the fourth side wall portion 140. The second crease portion 420 and the third crease portion 430 can be formed in parallel at places where the bottom portion 150 and the cover portion 160 meet the fourth side wall portion 140, respectively.

[0059] The detailed structure and function of the crease portion 400 will be described below.

[0060] Referring to Figure 2 and Figure 3 , the packaging cooling box 10 of the present disclosure includes an easy-adhesion portion 300.

[0061] Here, the easy-adhesion portion 300 refers to a member capable of repeatedly attaching and separating for the purpose of adhesion. The easy-adhesion portion uses an adhesion method by which a surface meets another surface to attach or separate from each other. In an embodiment, the easy-adhesion portion can include Velcro.

[0062] Specifically, the easy-adhesion portion 310 can attach the folded joint portion 200 to the side wall portion when assembled in a box mode. The easy-adhesion portion 310 provided on the first joint portion 210 or the fourth joint portion 240 functions to attach and separate from the easy-adhesion portion 310 provided on the fourth side wall portion 140. Also, the easy-adhesion portion 310 provided on the second joint portion 220 or the third joint portion 230 functions to attach and separate from the easy-adhesion portion 310 provided on the second side wall portion 120.

[0063] Also, the easy-adhesion portion 320 can join opposite two surfaces when the folded joint portion 200 is folded during assembly in a box mode. The easy-adhesion portion 320 provided on the first joint portion 210 to the fourth joint portion 240 functions to attach and separate the two surfaces opposite to each other when each joint portion is folded.

[0064] Also, the easy-adhesion portion 330, 340 can join the cover portion 160 to the side wall portion during assembly in a box mode. The easy-adhesion portion 330 can be provided on the flaps 161, 162, 163 integrally connected with the cover portion 160. Meanwhile, the easy-adhesion portion 340 can be formed on the upper portion of the side wall portion. The easy-adhesion portion 340 can be provided on the upper portion of the first side wall portion 110, the second side wall portion 120, and the third side wall portion 130, each of which corresponds to the easy-adhesion portion 330 provided on the flaps 161, 162, 163.

[0065] Also, the easy-adhesion portions 350, 360 are provided on the inner side of any one of the side wall portions to join the partition 170 thereto (see Figure 8 and Figure 9 ). The easy-adhesion portion 350 can be vertically provided on the first side wall portion 110 or the third side wall portion 130, and at the same time, the easy-adhesion portion 360 can be provided on both end portions of the partition 170.

[0066] The detailed conversion process and function of the partition 170 will be described below in detail.

[0067] Referring to Figure 3 The handle 164, the label 165, and the delivery note attachment 164 can be provided on the outside of the cover portion 160.

[0068] The handle 164 is located at the center of the cover portion 160 so that, when a user pulls up the packaging cooler 10 in the box mode, a holding capacity is uniformly applied, and the holding capacity prevents the load from sliding to one side.

[0069] The label 165 can include a barcode label having delivery information. As such, since the label 165 is provided on the outside of the cover portion 160, information can be easily checked through a barcode scanner or the like during the delivery process in the box mode.

[0070] Further, the delivery note attachment 166 can be provided so that a delivery note can be inserted therein. The delivery note attachment 166 is constructed of a plastic package to facilitate insertion, verification, and removal of the delivery note so that a remaining portion (indicated by a dotted line in Figure 3 ) other than the insert can be provided as being stitched to the cover portion 160.

[0071] According to Figure 3 an embodiment of the label 165 can be provided at a different position independently of the delivery note attachment 166. In contrast, the label 165 can be provided as being included in the delivery note attachment 166.

[0072] Figure 4 is a perspective view showing a process of assembling the packaging cooler of the disclosure from an unfolded state to a box mode.

[0073] Referring to Figure 4 , the packaging cooler 10 can be converted from an unfolded mode in which a box is unfolded (see Figure 2 ) to a box mode in which a space in which food is accommodated is provided (see Figure 1 ), and vice versa.

[0074] The side wall portions 110, 120, 130, 140, the bottom portion 150, and the cover portion 160 constituting a hexahedron in the box mode are configured to be unfolded into a single plane in the unfolded mode. Adjacent side edges of the side wall portions, which are positioned to meet in the box mode, become spaced apart from each other with intervals in the unfolded mode. The joint portions 200 are formed in the intervals, so that the side wall portions 110, 120, 130, 140, which are joined together by the bottom portion 150 as a center, can form a single rectangular shape as a whole.

[0075] In detail, the first side wall portion 110 and the fourth side wall portion 140 each have adjacent sides: their adjacent sides meet in the box mode, and become separated as the packaging cooling box is converted into the unfolded mode. In order to join the thus spaced apart adjacent sides together, a first joint portion 210 is formed. In the unfolded mode, the first joint portion 210 constitutes a single plane with the first side wall portion 110 and the fourth side wall portion 140. In this way, a second joint portion 220, a third joint portion 230, and a fourth joint portion 240 can each constitute a single plane with the respective adjacent side wall portions.

[0076] As a result, it is possible to provide a shape that enables complete cleaning and minimizes obstacles to automation of cleaning when the packaging cooling box 10 is converted into the unfolded mode and then introduced into the cleaning apparatus. Advantages resulting from the cleaning apparatus of the present disclosure will be further explained later.

[0077] On the other hand, the joint portions 200 can each have a rounded corner. For example, the first joint portion 210 is configured to be joined with the first side wall portion 110 and the fourth side wall portion 140, and the remaining portion of its edge can be rounded. In this way, the second joint portion 220, the third joint portion 230, and the fourth joint portion 240 are each configured to be joined with the respective adjacent side wall portions, and the remaining portion of their edges can be rounded. Thus, the side wall portions 110, 120, 130, 140, which are joined together by the bottom portion 150 as the center, can form a rounded single rectangular shape as a whole with the joint portions 200. Accordingly, a user can easily manipulate the packaging cooling box 10 in the unfolded mode, and cleaning automation can be smoothly performed.

[0078] Reference Figure 4 The joint portions 200 can be configured to be folded when converted from the unfolded mode to the box mode. In other words, the joint portions 200 can maintain physical connection with the adjacent side wall portions even when converted to the box mode. In the box mode, where the adjacent sides of the side wall portions meet, loss (hereinafter, collectively referred to as "heat loss") can easily occur due to heat leakage or heat inflow. By the joint portions 200 configured to be joined with the side wall portions, heat loss can be effectively prevented.

[0079] As such, the joint portions 200 provided in the packaging cooling box 10 of the present disclosure function so that cleaning can be smoothly performed by the cleaning apparatus in the unfolded mode, and they also function in the box mode so that heat loss in the vulnerable portion can be prevented to enhance the overall cooling function.

[0080] Reference Figure 4When assembled in the box mode, the unfolded first and second side wall portions 110 and 120 stand up so that the adjacent sides of each side wall portion become closer to each other. At this time, a diagonal fold line will be formed in the second joint portion 220 coupled with the adjacent sides, in which the second joint portion 220 is folded along the fold line. The second joint portion 220 folded to face itself stands up completely to be in close contact with the inner side of the first or second side wall portion 110 or 120. This deformation can be performed in the same manner in the first, third, and fourth joint portions 210, 230, and 240. In addition, this deformation can be performed simultaneously using the first, third, and fourth joint portions 210, 230, and 240.

[0081] In addition, when the packaging cold box is converted from the unfolded mode to the box mode, the easy-adhesion portion 300 can be provided so that the joint portion 200 can be maintained in the folded position and the folded joint portion 200 can be maintained close to the side wall portion. In other words, when the joint portion 200 is folded, the opposite two faces can be adhered to each other by the provided easy-adhesion portion 300, and the folded joint portion 200 becomes in close contact with the side wall portion and can be adhered to the side wall portion.

[0082] In detail, referring to Figure 4 When the second joint portion 220 is folded, the opposite two faces can be adhered to each other by the easy-adhesion portion 320 provided outside the second joint portion 220.

[0083] In an embodiment, the easy-adhesion portions 323 for coupling with the folded second joint portion 220 can be formed symmetrically to each other in the second joint portion 220 along the side edges thereof adjacent to the side wall portion. As such, since the easy-adhesion portions 323 are formed along the side edges adjacent to the side wall portion corresponding to the above-described vulnerable portion, heat efficiency can be improved and a stable box mode can be maintained.

[0084] In yet another embodiment, the easy-adhesion portions 321 can be formed symmetrically to each other along the edges of the second joint portion 220. Since the easy-adhesion portions 323 are supplemented, the second joint portion 220 can be in close contact with the side wall portion to maintain a more stable attachment thereto.

[0085] In another aspect, referring to Figure 4The fourth folded joint portion 240 has an easy-adhesion portion 310 for attachment to the fourth side wall portion 140. The fourth side wall portion 140 has an easy-adhesion portion 311 at the top, and the inner side of the fourth joint portion 240 has an easy-adhesion portion 312 corresponding thereto. In other words, the easy-adhesion portion 312 is provided on the portion of the inner side edge of the fourth joint portion 240 that is in close contact with the fourth side wall portion 140 when converted into the box mode. Since the folded joint portion is adhered to the side wall portion by the easy-adhesion portion 310 in the box mode, a space for containing food can be secured in the packaging cooling box without any obstacle.

[0086] The easy-adhesion portions 310, 320 having such a configuration or shape can be provided on the four joint portions 210, 220, 230, 240 in the same manner. Also, the adhesion process can be performed in the four joint portions 210, 220, 230, 240 in the same manner when the packaging cooling box is converted into the box mode. As such, the four joint portions 200 located between the side wall portions have the easy-adhesion portions 310, 320 so that they can be folded onto themselves and maintain the shape when the packaging cooling box is converted into the box mode, and the folded joint portions 200 can be adhered to the inner side of the side wall portions, thereby reducing heat loss due to a gap between the side wall portions and reliably maintaining the shape of the box.

[0087] As such, the packaging cooling box of the present disclosure can be easily converted from the unfolded mode into the box mode and vice versa, and heat loss in a vulnerable portion substantially accompanying the conversion is minimized. Also, full-automatic cleaning can be implemented in the unfolded mode, thereby significantly improving the recyclability of the packaging box. Accordingly, the packaging cooling box can replace a disposable packaging box, thereby reducing waste associated with exponentially increasing delivery demand. In particular, for delivery food requiring a cooling function, recycling of the packaging box for delivery can also be achieved.

[0088] Figure 5 is a cross-sectional view of an embodiment of a crease portion of the packaging cooling box of the present disclosure in the unfolded mode; Figure 6 is a cross-sectional view of an embodiment of a crease portion of the packaging cooling box of the present disclosure in the folded mode; and Figure 7 is a cross-sectional view of an embodiment of a side wall portion of the packaging cooling box of the present disclosure.

[0089] Referring to the above-described drawings, the side wall portions 110, 120, 130, 140, the bottom portion 150, and the cover portion 160 constitute a hexahedron in the box mode, in which the foam board 11 is contained. The foam board 11 can maintain a plate shape, and is made of a heat-insulating material for cooling, such as high-density expanded polypropylene (EPP).

[0090] An inner cover 12 and an outer cover 13 can be provided to accommodate the foam plate 11. The inner cover 12 can be made of silver or foil for heat insulation or cooling. The outer cover 13 can protect the foam plate 11 located inside from being torn due to external causes, and is made of a waterproof tarpaulin.

[0091] Figure 7 A cross-sectional view of an upper portion of the second side wall portion 120 in which the easily adherable portions 311, 321 are located is shown. Referring to Figure 7 , the easily adherable portions 311, 321 can be attached to the inner cover 12 and the outer cover 13, respectively, on the faces opposite the foam plate 11.

[0092] The crease portion 400 can be provided between the side wall portions 110, 120, 130, 140 and the bottom portion 150, and between the fourth side wall portion 140 and the cover portion 160 Figure 2 . Referring to Figure 5 and Figure 6 , the crease portion 400 can include grooves spaced apart at a predetermined interval (D1). The crease portion 400 in which the grooves are formed has only the inner cover 12 and the outer cover 13, without the foam plate 11. The crease portion 400 in which the grooves are formed can be configured to have a thickness smaller than a thickness (D2) of a portion in which the foam plate 11 is contained.

[0093] The side wall portions 110, 120, 130, 140 can be easily erected from the bottom portion 150, and the cover portion 160 can also be easily folded from the fourth side wall portion 140 during conversion into the box mode, as the foam plates 11 are separated from each other on the crease portion 400.

[0094] In addition, the grooves are formed in the crease portion 400, so that contaminants in the crease portion 400 can be completely removed when cleaning after conversion into the unfolded mode. Contamination of the bottom portion 150 can be caused by a portion of food contained in the box mode but leaked therefrom. In particular, the contaminants can be hardened in the crease portions 410, 420 located along the edges of the bottom portion 150, and are not easily removed even in a cleaning device. Since the grooves are formed in the crease portion 400 at a predetermined interval, a small gap can be ensured even when the side wall portions 110, 120, 130, 140 are erected from the bottom portion 150 by conversion into the box mode, and thus the introduced contaminants can be easily removed by the cleaning device without being hardened.

[0095] Figure 8 is a perspective view showing insertion of a spacer in the process of assembling the packaging cooling box of the present disclosure into a box mode; Figure 9 is a perspective view of an embodiment of a spacer that has been completely inserted; Figure 10This is a cross-sectional view showing an embodiment with the partition fully inserted; and Figure 11 This is a template illustrating an embodiment of the partition that constitutes the packaging cooling box of this disclosure.

[0096] Referring to the above figures, the packaging cooling box 10 may include a partition 170 to divide the internal space in the box configuration into a refrigerated space S1 and a room temperature space S2.

[0097] refer to Figure 11 The partition 170, in its unfolded position, can consist of a single plane. The partition 170 can have a rectangular shape, but can be formed with rounded corners for ease of user operation.

[0098] The partition 170 may have easily adhesive portions 361, 362 at both ends. The partition 170 may be along the longitudinal direction ( Figure 11 The partition 170 can be configured such that the easily adhesive portions 361, 362 located at its two ends can contact a surface during its rolling. As a result, a separate space is formed inside the rolled-up partition 170, and the cooling capacity is enhanced by the double insulating walls within the space. Thus, an environment is provided in which this space can be used as a refrigerated space S1. In other words, the refrigerated space S1 has double insulating walls formed by the partition 170 and the hexahedron of the packaging box 10, thereby preventing heat loss and allowing refrigerated food to be stored for a longer period of time.

[0099] On the other hand, the space outside the partition 170 but inside the hexahedron of the packaging box 10 can be used as a room temperature space S2, which is suitable for long-term storage of room temperature food. By providing the partition 170 therein, the interior of the packaging box 10 can simultaneously have space for storing refrigerated food under optimal conditions for a long time and space for storing room temperature food.

[0100] In an embodiment of the attachment layer 170, reference is made to... Figure 10 The partition 170 can be rolled up downwards so that the adhesive portion 361 at one end and the adhesive portion 362 at the other end can be simultaneously attached to the adhesive portion provided in the third sidewall portion 130.

[0101] In another embodiment, an adhesive portion 361 disposed at one end of the partition 170 can be attached to the middle portion of the third sidewall portion 130, thereby forming a larger refrigerated space S1 in the lower portion depending on the shape and size of the refrigerated food to be contained.

[0102] In addition, refer to Figure 8 and Figure 9In the process of a user separating food into refrigerated and room-temperature foods and storing them in the packaging box 10, he / she can first place the refrigerated food in, while attaching one end of the divider 170 to the lower end of the easy-to-adhere portion 350, and then attaching the other end of the divider 170 to the upper end of the easy-to-adhere portion 350. Once the divider 170 is fully attached, the user can place the room-temperature food into the remaining space separated by the divider 170 to complete the storage of the contents, and immediately close the lid portion 160, thus making the state ready for delivery. In this way, the easy-to-adhere portions 360 located at both ends of the divider 170 can separate the space through a quick and easy process, and under optimal conditions accommodate food suitable for each corresponding space.

[0103] Figure 12 The packaging cooling box of this disclosure is shown for cleaning.

[0104] refer to Figure 12 The packaging box 10 is configured such that it can unfold into a single plane in unfolded mode, and the unfolded packaging box 10 can be introduced into the cleaning device M for automatic cleaning.

[0105] Cleaning device M is configured such that when the packaging box 10 is in unfolded mode, it moves in a specific direction ( Figure 12 When the direction of the middle arrow passes through the cleaning device M, the inner and outer surfaces of the unfolded portion can be cleaned automatically. At this time, when the packaging box 10 is a single plane and has a simple shape such as a rectangle, the cleaning process of the packaging box 10 can become easy and thorough. In the case of a single plane with a complex shape such as a cross or a protruding shape, obstacles increase when implementing automatic cleaning, such as blockages occurring during the cleaning process.

[0106] In other words, if the respective joining portions 200 are not provided, and therefore the adjacent sides of the sidewall portions are configured to be separated from each other in the unfolded mode of the packaging box 10, the first sidewall portion 110 and the third sidewall portion 130 will act as protrusions during their introduction into the cleaning device M, and degrade the cleaning process.

[0107] Thus, the packaging box 10 according to this disclosure has a connecting portion 200 connecting adjacent sidewall portions to simplify the shape in the unfolded mode into a rectangle, thereby achieving perfect cleaning optimized for the cleaning equipment M.

[0108] Figure 13 This is a perspective view illustrating the process of assembling the packaging cooling box of this disclosure from an unfolded mode to a portable mode; and Figure 14 This is a perspective view showing the packaging cooling box of the present invention, which has been fully assembled into a portable mode.

[0109] In addition to the side wall portions 110, 120, 130, 140, the bottom portion 150, and the cover portion 160, the packaging box 10 according to the present disclosure has the joint portions 200 and the easy-adhesion portions 300, and thus can be converted into a portable mode. The packaging box 10 using such a portable mode can be used, for example, when the contents are taken out of the packaging box 10 upon completion of delivery, and then the volume and size thereof need to be minimized for delivery to a transportation company.

[0110] Now, the process of converting from the unfolded mode to the portable mode will be explained. First, the first side wall portion 110 and the third side wall portion 130 and the adjacent first joint portion 210 to the fourth joint portion 240 are folded inward. Next, the separate partition 170 is placed at the position where the first side wall portion 110, the third side wall portion 130, etc. are folded inward. At this time, one end portion of the partition 170 can be attached to the second side wall portion 120. Then, the second side wall portion 120 is folded inward. Then, the cover portion 160 is folded inward, and the easy-adhesion portion 333 provided on the flap 163 is attached to the adhesion portion 343 provided outside the second side wall portion 120.

[0111] Reference Figure 14 The upper portion of the packaging box 10 completely converted into the portable mode still has the handle 164 located in the center of the cover portion 160 and exposed therefrom, and thus the user can easily grasp the handle 164 to move the packaging box 10.

[0112] On the other hand, the fixing function of the partition 170 in the portable mode will be explained in detail as follows: The easy-adhesion portion 311 can be provided on the upper end portion of the second side wall portion 120 over the entire width thereof from one side to the other side. That is, the easy-adhesion portion 311 provided on the second side wall portion 120 can be configured to extend to the middle portion of the second side wall portion 120 beyond the portion corresponding to the easy-adhesion portion 312 provided on the third joint portion 230 and the fourth joint portion 240, which can be attached to or separated from the middle portion, or configured to be connected at the middle portion.

[0113] As a result, during the mode conversion into the portable mode, it can be attached to the easy-adhesion portion 361 provided at one end portion of the partition 170. Although the third joint portion 230 and the fourth joint portion 240 are folded inward, a portion of the easy-adhesion portion 311 can be exposed in the extended middle portion, and the partition 170 can be fixed to the exposed portion of the easy-adhesion portion 311 and can be safely accommodated without falling in the portable mode.

[0114] The above-described embodiments are merely examples and other embodiments can be implemented within the scope of the following claims.
