Description

Technical Field

[0001] The embodiments of the present invention relate to a container, and in particular to a foldable thermal insulation box. Background Art

[0002] Existing insulation containers are generally made of EPS and EPP foam materials, which have good toughness but poor rigidity. When in use, after placing the goods in the container, put the lid on the box body and then deliver it. Such insulation boxes generally have an outer size of 600*400*300mm and a content volume of about 45 liters. Such insulation containers are mainly used for fresh food delivery. After the pre-cooled fresh or frozen products are sorted in the cold storage, they are loaded into insulation boxes together with cold storage plates and then delivered to households. Such insulation boxes generally have side panels and bases that are integrally formed, and are standard fixed boxes. The transportation of insulation boxes will take up a large transportation space, and the transportation and storage costs are relatively high. In addition, the insulation box needs to be recycled. After the goods are transported, the insulation box needs to be recycled and taken back. The insulation box will also take up a large space during recycling transportation, making the return freight high. Summary of the invention

[0054] The following describes embodiments of the present invention with reference to the accompanying drawings. Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the foldable heat preservation box 100 includes a box body 20 with an opening 30, a cover 4 covering the opening 30, and a cold storage member 42 disposed in the foldable heat preservation box 100. The box body 20 has a base 1 and two pairs of opposite side panels 2 and 3 that are foldable with the base 1. The side panels 2 and 3 are both hinged to the base 1 through hinges, and the hinges can operably cover the gaps between the corresponding side panels and the base 1. Figure 5 As shown, the side panel 2 is hinged to the base 1 through the hinge 5, and the side panel 3 is hinged to the base 1 through the hinge 5. The longitudinal ends of the side panels 2 and 3 are respectively provided with bite parts 202 and 302. When each side panel is erected relative to the base 1, the hinge 5 is straightened to cover the docking area between the side panel 2 and the base 1, and the hinge 6 is straightened to cover the docking area between the side panel 3 and the base 1. The side panels 2 and 3 are connected to each other through the bite parts 202 and 302, so as to form the internal volume of the foldable container 100 together with the base 1, and the lid 4 can cover the opening 30 of the foldable thermal insulation box 100. When each side panel 2, 3 and the lid 4 are folded relative to the base 1, the hinge 5 and the hinge 6 are bent, so that the volume of the box body 20 is reduced, and it can be conveniently stored and transported. It should be understood that the connection method between the side panels 2 and 3 is not limited to the above bite method, as long as they can be connected end to end to enclose the internal space.

[0055] From the above content, it can be known that due to the provision of hinges, the side panels 2 and 3 are hinged to the base 1 through the hinges 5 and 6, so that the side panels 2, 3 and the base 1 can be folded, which can be conveniently stored and transported, and the space occupied during the transportation and storage of the thermal insulation box is reduced, and the transportation and storage costs are reduced. In addition, the hinges cover the gap between the corresponding side panels and the base 1, reducing the energy loss of the hinged parts of the box body 20 and improving the overall thermal insulation effect of the box body 20.

[0056] The structures in which the two side panels 2 are hinged to the base 1 through the hinge 5 are the same, and the structure in which one side panel 2 is connected through one hinge 5 is taken as an example. The hinge 5 includes: a first mounting portion 51, a second mounting portion 52 and a connecting plate 53, the first mounting portion 51 is connected to the side panel 2, the second mounting portion 52 is connected to the base 1, the first mounting portion 51 and the second mounting portion 52 are arranged on the upper and lower sides of the connecting plate 53, and the connecting plate 53 covers the gap between the side panel 2 and the base 1.

[0057] Furthermore, if Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the connecting plate 53 has a first mounting plate 531 connected to the first mounting portion 51, a second mounting plate 532 connected to the second mounting portion 52, and a flexible plate 533 connected to the first mounting plate 531 and the second mounting plate 532, and the first mounting plate 531 and the second mounting plate 532 are arranged on the upper and lower sides of the flexible plate 533. The first mounting plate 531, the second mounting plate 532 and the flexible plate 533 all extend along the length direction of the side plate 5. The thickness of the flexible plate 533 is less than the thickness of the first mounting plate 531 and the second mounting plate 532, so that when the side plate 2 is folded, the flexible plate 533 is bent, and the thickness of the second mounting plate 532 and the first mounting plate 531 can be maintained to allow the box 20 to have good cold storage. It can be understood that the thickness of the flexible plate 533, the second mounting plate 532 and the first mounting plate 531 can also be the same. The flexible plate 533 can be a plastic part, a silicone part or a steel plate. The flexible board 533, the second mounting board 532 and the first mounting board 531 may be integral parts of the same material, or the second mounting board 532 and the first mounting board 531 may be made of different materials from the flexible board 533, and the flexible board 533 is connected and spliced ​​with the second mounting board 532 and the first mounting board 531.

[0058] Furthermore, if Figure 4 , Figure 6 and Figure 7 As shown, the first mounting portion 51 has a plurality of first embedding bolts 511 embedded in the corresponding side panels 2. The first embedding bolts 511 are arranged along the length direction of the side panels 2.

[0059] Furthermore, if Figure 6 and Figure 7 As shown, the second mounting portion 52 has a plurality of second embedding bolts 521 embedded in the base 1. The second embedding bolts 521 are arranged along the length direction of the side plate 2.

[0060] In addition, the first mounting portion 51 , the second mounting portion 52 and the connecting plate 53 are integrally formed.

[0061] Furthermore, if Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the side plate 2 has a first side plate body 21, and a first extension plate 22 extending downward from the bottom side of the first side plate body 21. The base 1 has a bottom plate 11, and a pair of opposite first edge guards 12 extending upward from a pair of opposite edges of the bottom plate 11, and one first edge guard 12 corresponds to one first extension plate 22, and each first extension plate 22 is operably engaged with the corresponding first edge guard 12. Among them, each first extension plate 22 is connected to the first mounting portion 51, and each first edge guard 12 is connected to the second mounting portion 52. And the flexible plate 53 covers at least part of the first extension plate 22, and extends from the lower edge of the first extension plate 22 to the first edge guard 12 corresponding to the first extension plate 22.

[0062] Furthermore, the box body 20 is generally made of EPS or EPP foaming material. In order to ensure the heat preservation effect, the box body 20 is kept at a certain thickness. In order not to change the volume of the box body 20 and to ensure the thickness of the box body 20, the hinge is embedded in the box body 20. That is, at least part of the first mounting plate 531 and the top of the flexible plate 533 are embedded in the side of the first extension portion facing the inside of the box body 20, and at least part of the second mounting plate 532 and the bottom of the flexible member are embedded in the side of the first edge guard 12 facing the inside of the box body 20. And the hinge 5 is inside the box body 20, so that the outer surface of the box body 20 maintains structural integrity. It can be understood that the hinge 5 can be set on the outer surface of the box body 20.

[0063] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, each first extension plate 22 is provided with a first groove 221 with an opening 30 facing outward and downward on the outer side. The first edge guard 12 has a first protrusion 121, which is embedded in the first groove 221 of the corresponding first extension plate 22 and abuts against the wall of the first groove 221. The flexible plate 533 covers the lower edge 220 of the first extension plate 22 facing the inside of the box 20, and the flexible plate 533 also covers the upper edge 120 of the first edge guard 12 facing the inside of the box 20, so that the gap between the lower edge 220 and the upper edge 120 is covered by the flexible plate 533, and the cold in the box 20 will not flow out from between the lower edge 220 and the upper edge 120, so that even if the side plate 2 and the base 11 are not an integral part, the cold in the box 20 is not easy to lose.

[0064] Furthermore, if Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7As shown, the arrangement of the first extension plate 22 facilitates the opening of the through hole 222 on the first extension plate 22. The first embedded bolt 511 is inserted into the through hole 222 and penetrates the first extension plate 22. The hook at the end of the first embedded bolt 511 hooks the first extension plate 22, thereby realizing a large number of positioning and fixing areas between the first embedded bolt 511 and the side plate 2. Although the side plate 2 has good toughness and poor rigidity, the first embedded bolt 511 is stably connected to the side plate 2. The first protrusion 121 abuts against the wall of the first groove 221, that is, the first protrusion 121 abuts against the side surface of the first extension plate 22 facing the outside of the box body 20. The first protrusion 121 blocks the through hole 222 to prevent the leakage of cold energy from the through hole 222, and also protects the first embedded bolt 511. When the side panel 2 is vertical, the first protrusion 121 and the wall of the first groove 221 are supported against each other, so that the thickness of the first protrusion 121 and the first extension plate 22 combined together is basically the same as the thickness of the first side panel body 21, so that the thickness of the side wall of the box body 20 is guaranteed and has better thermal insulation.

[0065] Furthermore, if Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the first edge guard 12 has a first docking portion 123 extending upward, the upper edge 120 is on the first docking portion 123, the first docking portion 123 is abutted against the lower bottom surface of the first extension plate 22, and the first docking portion 123 is separated from the first protruding portion 121, so that it is convenient to open a through hole 122 on the first docking portion 123. The second embedded bolt 521 is inserted into the through hole 122 and penetrates the first docking portion 123, and the hook body at the end of the second embedded bolt 521 hooks the side of the first docking portion 123 facing the first protruding portion 121, so that the second embedded bolt 521 and the first edge guard 12 have a large number of positioning and fixing areas, and the second embedded bolt 521 is stably connected to the first edge guard 12 even though the base 1 has good toughness and poor rigidity. The first protrusion 121 covers the area between the first docking portion 123 and the first extension plate 22 and also covers the through hole 122 to prevent cold leakage from the through hole 222 and between the first docking portion 123 and the first extension plate 22 , and also protects the second embedded bolt 521 .

[0066] In addition, if Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the side panel 3 is connected to the base 1 through a hinge 6. The structure of the hinge 6 may be the same as that of the hinge 5, or may be different. Now, the hinge 6 is taken as another structure to connect the base 1 and the side panel 3 for explanation. Among them, the structure in which the two side panels 3 are hinged to the base 1 through the hinge 6 is the same. Now, the structure in which one side panel 3 is connected through a hinge 6 is taken as an example. The hinge 6 includes: a first mounting portion 61, a second mounting portion 62 and a connecting plate 63. The first mounting portion 61 is connected to the side panel 2, and the second mounting portion 62 is connected to the base 1. The first mounting portion 61 and the second mounting portion 62 are arranged on the upper and lower sides of the connecting plate 63, and the connecting plate 63 covers the gap between the side panel 2 and the base 1.

[0067] Furthermore, if Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, the connecting plate 63 has a first mounting plate 631 connected to the first mounting portion 61, a second mounting plate 632 connected to the second mounting portion 62, and a flexible plate 633 connected to the first mounting plate 631 and the second mounting plate 632, and the first mounting plate 631 and the second mounting plate 632 are arranged on the upper and lower sides of the flexible plate 633. The first mounting plate 631, the second mounting plate 632 and the flexible plate 633 all extend along the length direction of the side plate 6. The thickness of the flexible plate 633 is less than the thickness of the first mounting plate 631 and the second mounting plate 632, so that when the side plate 3 is folded, the flexible plate 633 is deformed by tension, and the thickness of the second mounting plate 632 and the first mounting plate 631 can be maintained to allow the box 20 to have good cold storage. It can be understood that the thickness of the flexible plate 633, the second mounting plate 632 and the first mounting plate 631 can also be the same. The flexible plate 633 can be a plastic part, a silicone part or a steel plate. The flexible board 633 , the second mounting board 632 and the first mounting board 631 may be integral parts of the same material, or the second mounting board 632 and the first mounting board 631 may be made of different materials from the flexible board 633 , and the flexible board 633 is connected and spliced ​​with the second mounting board 632 and the first mounting board 631 .

[0068] Further, the first mounting portion 61 has a plurality of first embedding bolts 611 embedded in the corresponding side panels 3. The first embedding bolts 611 are arranged along the length direction of the side panels 3. It can be understood that the first mounting portion can be an adhesive layer.

[0069] Further, the second mounting portion 62 has a plurality of second embedding bolts 621 embedded in the base 1. The second embedding bolts 621 are arranged along the length direction of the side plate 3. It can be understood that the second mounting portion can be an adhesive layer.

[0070] In addition, the first mounting portion 61 , the second mounting portion 62 and the connecting plate 63 are integrally formed.

[0071] Furthermore, if Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the side panel 3 has a second side panel body 31, and a second extension panel 32 extending downward from the bottom side of the second side panel body 31. The base 1 also has a pair of opposite second edge guards 13 extending upward from the other pair of opposite edges of the bottom panel 11, and one second edge guard 13 corresponds to one second extension panel 32, and each second extension panel 32 is operably engaged with the corresponding second edge guard 13. Among them, each second extension panel 32 is connected to a first mounting portion 61; the flexible plate 63 is operably covering the lower corner end 320 of the second extension panel 32 facing the box body 20, the first mounting plate 631 covers the side of the second extension panel 32 facing the box body 20, and the second mounting plate 632 covers the side of the second extension panel 32 facing the bottom panel 11; the second mounting portion 62 extends downward and is connected to the bottom panel 11, and the first mounting portion 61 is connected to the second extension panel 32.

[0072] Furthermore, if Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the first mounting plate 631 is embedded in a side of the second extension plate 32 facing the inside of the box body 20 , and the second mounting plate 632 is embedded in a side of the second extension plate 32 facing the bottom plate 11 .

[0073] In addition, if Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, the bottom plate 11 has a receiving portion 110 arranged opposite to the second extension plate 32, wherein the second mounting portion is inserted into the receiving portion 110. A through hole 111 is provided on the receiving portion 110. For the convenience of processing, the through hole 111 passes through the receiving portion 110. The second extension plate 32 blocks the through hole 111, preventing the cold from leaking from the through hole 111. The position of the through hole 111 also avoids the area on the bottom plate 11 for placing items, so that the items can be placed in the bottom plate 11 area without gaps, ensuring the safety of the items. The area between the lower bottom surface of the second extension plate 32 and the receiving portion 110 is blocked by the second mounting plate 632 and the flexible plate 633, preventing the cold from leaking between the lower bottom surface of the second extension plate 32 and the receiving portion 110. The second mounting portion 62 extends downward to block part of the gap, further improving the insulation effect of the foldable thermal insulation box 100.

[0074] Further, such as Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the outer side of each second extension plate 32 is provided with a second groove 321 with an opening 30 facing outward and downward, and the second edge guard 13 is embedded in the corresponding second groove 321 and abuts against the wall of the second groove 321. The second edge guard 13 extends upward, shielding the area between the lower bottom surface of the second extension plate 32 and the receiving portion 110. The provision of the second extension plate 32 facilitates the opening of a second through hole on the second extension plate 32. The first embedded bolt 611 is inserted into the second through hole and penetrates the second extension plate 32, and the hook body at the end of the first embedded bolt 611 hooks the second extension plate 32, thereby realizing a large number of positioning and fixing areas between the first embedded bolt 611 and the side plate 3. Although the side plate 3 has good toughness and poor rigidity, the first embedded bolt 611 is stably connected to the side plate 3. The second edge guard 13 abuts against the wall of the second groove 321, that is, the second edge guard 13 abuts against the side of the second extension plate 32 facing the outside of the box body 20, and the second edge guard 13 blocks the second through hole to prevent the leakage of cold energy from the second through hole, and also protects the first embedded bolt 611. When the side plate 3 is vertical, the second edge guard 13 abuts against the wall of the second groove 321, so that the thickness of the second edge guard 13 and the second extension plate 32 combined is basically the same as the thickness of the second side plate body 31, so that the thickness of the side wall of the box body 20 is guaranteed, and it has better thermal insulation. And the first mounting plate 631 extends upward beyond the height of the first embedded bolt 611.

[0075] Furthermore, if Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the height of the first edge guard 12 is higher than the height of the second edge guard 13 .

[0076] like Figure 6 and Figure 7 As shown, the side panel 3 can be folded into the box body 20, and after folding, it abuts against the bottom panel 11. The side panel 2 can be folded into the box body 20, and is located above the side panel 3. That is, when folding, the side panel 3 is folded down first, and then the side panel 2 is folded down. Since the height of the first edge guard 12 is higher than the height of the second edge guard 13, the side panel 2 can be directly on the side panel 3 after folding, and will not be interfered by the side panel 3 and cannot be folded.

[0077] Furthermore, if Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, the side panel 2 has a pair of bending portions 23, which are bent and extended from the edge of the side panel 2 in the length direction toward the side panel 3. The bending portion 23 has a bite portion 202, which is a plurality of bosses facing the inside of the box body 20, and an embedding groove is formed between two adjacent bosses, and the bosses are arranged along the height direction of the box body 20. Similarly, the bite portion 302 is a plurality of bosses facing the outside of the box body 20, and an embedding groove is formed between two adjacent bosses, and the bosses are arranged along the height direction of the box body 20. The boss of the bite portion 302 is inserted into the embedding groove of the bite portion 202, and the boss of the bite portion 202 is inserted into the embedding groove of the bite portion 302, so as to realize the bite fixation of the side panels 2 and 3. When folding, the side panel 3 can be folded downward first, and the side panel 3 and the receiving portion 110 fall down and are located between the two second edge guards 13. After the side panel 2 is folded, the two bending portions 23 are respectively against the tops of the two second edge guards 13. The side plate 2 is covered on the side plate 3 . The cover 4 is operably covered on the side plate 2 , and a pair of opposite edges of the cover 4 overlap the top of the first edge guard 12 .

[0078] In addition, if Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the cover 4 has a cover body 41 and a cold storage member 42 arranged on the cover body 41. The cold storage member 42 can be a cold storage plate filled with cold storage agent. The cover body 4 has a hook body 420 for hooking the cold storage member 42 on the side facing the box body 20. After the side panels 2 and 3 are folded, the hook body 420 can be operably overlapped in the first groove 221. This makes the volume of the folded insulation box smaller. The tops of the side panels 2 and 3 are both provided with protrusions 201, and the inner side of the cover body 41 is provided with a groove 411. When the side panels 2 and 3 are upright, the cover 4 covers the tops of the side panels 2 and 3, and the protrusions 201 of the side panels 2 and 3 are inserted into the groove 411 of the cover body 41, so that the cover body 4 covers the box body 20. In order to cover the cover 4 more tightly, there is a hook body 410 on the cover body 41 to hook the protrusion 201 of the side panel 3. When the side panels 2 and 3 are upright, that is, the incubator is in actual use.

[0079] Furthermore, if Figure 6 and Figure 7 As shown, after the two side panels 2 are folded, the two side panels 2 do not overlap, that is, the total height of the two side panels 2 is less than or equal to the length of one side panel 3. After the two side panels 3 are folded, the two side panels 3 do not overlap, that is, the total height of the two side panels 3 is less than or equal to the length of one side panel 3.

[0080] In addition, if Figure 1 and Figure 6 As shown, the side panel 2 is a long side panel with a longer length, and the side panel 3 is a short side panel with a shorter length. It can be understood that the side panel 3 can be a long side panel with a longer length, and the side panel 2 can be a short side panel with a shorter length.

[0081] In addition, the material of the hinge 5 and the hinge 6 is different from that of the side plate and the base 1. The hinge 5 and the hinge 6 can be made of plastic, silica gel and the like, and the side plate and the base 1 can be made of EPS, EPP foaming material.

[0082] In one embodiment, the hinge 5 can also be a hinge 6 structure to hinge the side panel 2 and the base 1, that is, the structure of the hinge 5 hinged to the side panel 2 and the base 1 and the structure of the hinge 6 hinged to the side panel 3 and the base 1 can be replaced or used in combination with each other, and are not limited to the above examples.

[0083] Preferred embodiments of the present invention have been described above in detail, but it should be understood that aspects of the embodiments can be modified, if necessary, to employ aspects, features and concepts of the various patents, applications and publications to provide further embodiments.

[0084] These and other changes can be made to the embodiments in light of the above detailed description.In general, in the claims, the terms used should not be considered limited to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which these claims are entitled.
