Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum insulation, specifically a vacuum insulation panel and an insulation box. Background Technology
[0002] In the process of packaging vacuum insulation panels, in order to reduce the overall volume, the excess packaging bags around the vacuum insulation panels need to be folded and fixed to the core material.
[0003] However, the corners of the folded structure of the outer bag of the existing vacuum insulation panel are not straight, and the outer bag at the corners is thicker, resulting in large gaps when the vacuum insulation panel is spliced, leading to serious loss of heat and cold. Utility Model Content
[0004] To address the above problems, this utility model provides a vacuum insulation panel and an insulation box, which can solve the problem of large gaps in the splicing of vacuum insulation panels leading to serious loss of heat and cold.
[0005] The first aspect of this utility model provides a vacuum insulation panel, which includes a core material and an outer bag. Both the core material and the outer bag are rectangular, with the length and width of the outer bag exceeding the core material to cover its surface. The core material includes a first side and a second side arranged opposite each other. A redundant portion of the outer bag, with an area larger than the core material, includes a first side, a second side, and a corner. The corner is located at the angle where the first and second sides connect. The redundant portion is fitted and fixed to the core material using a folding structure, closely conforming to the outline of the core material. With this arrangement, the outer bag can completely cover the surface of the core material, and the redundant portion can fit snugly against the corners of the core material.
[0006] The folding structure includes a first folding unit, a corner folding unit, and a second folding unit. The first folding unit is formed by folding the first edge inward and fitting it to the first surface in a manner that closely follows the contour of the core material. The crease of the first folding unit extends to the corner and folds the corner in half. The corner folding unit is formed by folding the folded corner inward and fitting it to the first edge and the first surface in a manner that closely follows the contour of the core material. The second folding unit is formed by folding the second edge inward and fitting it to the corner and the first surface in a manner that closely follows the contour of the core material.
[0007] By using the above method, the first side of the redundant part is first folded to the first surface, then the corner is folded to the first side and the first surface, and finally the remaining second side is folded to fit snugly against the first surface, the first side and the corner, so that the redundant part of the outer bag is wrapped flat around the corner of the core material, thereby improving the gaps when splicing vacuum insulation panels and reducing the loss of heat and cold during use.
[0008] Optionally, the core material includes a first sidewall and a second sidewall near the corner, the first sidewall being along the length of the core material and the second sidewall being along the width of the core material. In this way, core materials of different sizes can be spliced together according to their length and width using the first and / or second sidewalls.
[0009] Optionally, the first folded edge unit is formed by having a first edge tightly attached to the first sidewall of the core material. In this manner, the first folded edge unit can be folded along the length of the core material.
[0010] Optionally, the corner unit is formed by folding the corner against the first sidewall and the first surface of the core material. In this way, the corner of the outer bag is attached to the surface of the core material along the length of the core material, which helps to ensure that the corner of the outer bag is flat and attached to the corner of the core material.
[0011] Optionally, the second folded edge unit is formed by folding the second sidewall and the first surface of the core material together, with the second edge tightly pressed against it. In this way, the redundant part of the outer bag is completely fitted to the surface of the core material along the width direction, which helps to improve the gaps when splicing vacuum insulation panels.
[0012] Optionally, the corner unit is formed by folding the corner against the second sidewall and the first surface of the core material. In this way, the corner of the outer bag is attached to the surface of the core material along the width direction, ensuring that the corner of the outer bag is flush with the corner of the core material.
[0013] Optionally, the outer bag is positioned close to the sidewall of the core material, forming folds to completely cover the sidewall of the core material. In this way, the outer bag can fit snugly against the sidewall of the core material and enclose it.
[0014] A second aspect of this invention also provides an insulated box having the vacuum insulation panel described above. Through these methods, the gaps in the box body can be improved, reducing heat loss during use. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Figure 1 This is a schematic diagram of the structure of the vacuum insulation panel 100 with the folding structure 30 in the embodiment of this utility model. Figure 2 This is a front view of the vacuum insulation panel 100 in this embodiment of the present invention. Figure 3 This is a side view of the vacuum insulation panel 100 in this embodiment of the present invention. Figure 4 This is a first structural schematic diagram of the vacuum insulation panel 100 in this embodiment of the present invention.
[0026] Combination Figure 2 and Figure 3 and refer to Figure 1 The vacuum insulation panel 100 provided in this embodiment includes a core material 10 and an outer bag 20. The core material 10 is cuboid in shape, and the outer bag 20 is a rectangular pocket. The length and width of the outer bag 20 are both greater than the length and width of the core material 10, so that the outer bag 20 can completely contain the core material 10 and cover the panel surface of the core material 10. The panel surface of the core material 10 includes a first surface 11 (i.e., ...) disposed opposite to each other. Figure 1 The top surface of the core material 10) and the second surface 12 (i.e. Figure 1(The bottom surface of the core material 10). The outer bag 20 can be divided into a main part 21 and a redundant part 22. The main part 21 is where the outer bag 20 and the core material 10 are attached; that is, the area of the main part 21 is equal to the area of the core material 10. The part of the outer bag 20 with an area larger than the core material 10 is the redundant part 22, which is located at the four corners of the core material 10.
[0027] refer to Figure 4 Taking the lower right corner of the core material 10 as an example, the redundant portion 22 includes a first side 221, a second side 222, and a corner 223, with the corner 223 located at the corner where the first side 221 and the second side 222 connect. Using the folding structure 30, the redundant portion 22 is fitted and fixed to the core material 10 in a way that closely conforms to its contour. With this configuration, the main body 21 of the outer bag 20 can cover the surface of the core material 10, and the redundant portion 22 can conform to the contour of the core material 10, achieving a tight fit and wrapping of the core material 10.
[0028] Figure 5 This is a schematic diagram of the second structure of the vacuum insulation panel 100 in this embodiment of the present invention. Figure 6 This is a structural schematic diagram of the vacuum insulation panel 100 with the first folded edge unit 31 in an embodiment of this utility model. The following is in conjunction with... Figure 1 and refer to Figure 5 and Figure 6 The folding structure 30 formed by the redundant portion 22 of the outer bag 20 will be explained.
[0029] The folding structure 30 includes a first folding unit 31, a corner folding unit 32, and a second folding unit 33. The first edge 221 of the redundant portion 22 is folded inwards and adhered to the first surface 11 in a manner close to the contour of the core material 10, forming the first folding unit 31. The crease of the first folding unit 31 is extended to the corner 223 of the redundant portion 22, and the corner 223 is folded in half. The folded corner 223 is then folded inwards and adhered to the first edge 221 and the first surface 11 in a manner close to the contour of the core material 10, forming the corner folding unit 32. Next, the remaining second edge 222 of the redundant portion 22 is folded inwards and adhered to the corner 223 and the first surface 11 in a manner close to the contour of the core material 10, forming the second folding unit 33.
[0030] Continue to refer to Figure 1 In this embodiment of the utility model, for the redundant part 22 of the outer bag 20, the four corners of the core material 10 are wrapped with folding structures 30, that is, the core material 10 may include four folding structures 30.
[0031] In the above manner, the first side 221 of the redundant part 22 is first folded onto the first surface 11, and then the corner 223 is folded onto the first surface 11 according to the first side 221. Finally, the remaining second side 222 is folded onto the first surface 11 and fits together with the first side 221 and the corner 223, so that the redundant part 22 of the outer bag 20 is flatly wrapped around the corner of the core material 10, thereby improving the gap when splicing the vacuum insulation board 100 and reducing the loss of heat and cold during use.
[0032] like Figure 4 As shown, the outer bag 20 is tightly attached to the side wall of the core material 10 and forms a crease at the side wall of the core material 10, thereby completely covering the side wall of the core material 10. In this way, the outer bag 20 can fit against the side wall of the core material 10 and wrap the core material 10.
[0033] Furthermore, the folding structure 30 in this embodiment of the present invention can be folded manually or by a combination of machine and manual folding. The present invention does not limit the way the folding structure 30 is set.
[0034] like Figure 4 and Figure 5 As shown, the core material 10 includes a first sidewall 13 and a second sidewall 14 near the corner 223 of the outer bag 20. The first sidewall 13 is along the length direction of the core material 10, and the second sidewall 14 is along the width direction of the core material 10. In this way, core materials 10 of different sizes can be spliced together according to their length and width using the first sidewall 13 and / or the second sidewall 14.
[0035] Figure 6 This is a schematic diagram of the structure of the vacuum insulation panel with the first folded edge unit in an embodiment of the present invention. Figure 7 This is a schematic diagram of the vacuum insulation panel with angled units in an embodiment of the present invention. The embodiments of the present invention will be described in detail below.
[0036] <First Implementation Method>
[0037] Continue to refer to Figure 1 ,by Figure 1 Taking the lower right corner of the core material 10 as an example, the folding structure 30 will be explained in detail.
[0038] Combination Figure 1 and refer to Figure 5 and Figure 6 The first edge 221 is closely attached to the first sidewall 13 of the core material 10 to form the first folded edge unit 31. With this configuration, the first folded edge unit 31 can be folded along the length of the core material 10.
[0039] Combination Figure 6 and refer to Figure 7The crease of the first folding unit 31 is extended to the corner 223 of the redundant portion 22, and the corner 223 is folded along the crease. The folded corner 223 is first folded along the first sidewall 13 that is close to the core material 10, and then the remaining part of the corner 223 is folded towards the first surface 11 to form the corner unit 32. That is, a part of the corner 223 in the corner unit 32 is close to the first sidewall 13, and the other part is close to the first surface 11.
[0040] In this way, the corner 223 of the outer bag 20 is attached to the surface of the core material 10 along the length of the core material 10, which helps to ensure that the corner 223 of the outer bag 20 is attached to the corner of the core material 10 in a straight line.
[0041] Combination Figure 7 and refer to Figure 1 The second side 222 is folded tightly against the second sidewall 14 and the first surface 11 of the core material 10 to form the second folded edge unit 33. In this way, the redundant part 22 of the outer bag 20 is completely attached to the board surface of the core material 10 along the width direction of the core material 10, which facilitates the improvement of the gaps when splicing the vacuum insulation board 100.
[0042] The vacuum insulation panel 100 is wrapped as follows: the vacuum insulation panel 100 has four corners, with the upper right and lower right corners forming one group, and the upper left and lower left corners forming another group. The outer bag 20 is first folded along the side wall of the core material 10 to form four corresponding first folded edge units 31. The lower right and upper right corners are first folded against the front and rear side walls of the core material 10 respectively, and then folded towards the top surface of the core material 10 to form two corresponding corner units 32. The upper right and lower right corners are based on the same second edge 222 (i.e., Figure 1 The second edge 222 (located on the right side of the core material 10) is folded towards the top surface of the core material 10 to form a second folded edge unit 33. The upper left corner and the lower left corner are respectively folded against the front and rear sidewalls of the core material 10 towards the top surface of the core material 10 to form two corresponding corner units 32. The upper left corner and the lower left corner are based on the same second edge 222 (i.e., Figure 1 The second edge 222 located on the left side of the core material 10 is folded towards the top surface of the core material 10 to form another second folded edge unit 33, thereby wrapping the outline of the core material 10.
[0043] <Second Implementation Method>
[0044] In another embodiment of this utility model (not shown), the folding method of the corner unit 32 can also be to first fold the corner 223 along the second side wall 14, and then fold the corner 223 toward the first surface 11.
[0045] Correspondingly, the first folding unit 31 is formed by the first side 221 closely adhering to the second sidewall 14 of the core material 10. With this configuration, the first folding unit 31 can be folded along the width direction of the core material 10.
[0046] Extend the crease of the first folding unit 31 to the corner 223 of the redundant portion 22, and fold the corner 223 along the crease. The folded corner 223 is first folded along the second sidewall 14 of the core material 10, and then the remaining portion of the corner 223 is folded towards the first surface 11 to form the corner unit 32. That is, a portion of the corner 223 in the corner unit 32 is close to the second sidewall 14, and another portion is close to the first surface 11. In this way, the corner 223 of the outer bag 20 adheres to the surface of the core material 10 along the width direction of the core material 10, ensuring that the corner 223 of the outer bag 20 is flush with the corner of the core material 10.
[0047] The second side 222 is folded tightly against the first sidewall 13 and the first surface 11 of the core material 10 to form the second folded edge unit 33. In this way, the redundant part 22 of the outer bag 20 is completely attached to the board surface of the core material 10 along the length direction of the core material 10, thereby improving the gap when the vacuum insulation board 100 is spliced.
[0048] The vacuum insulation panel 100 is wrapped as follows: the vacuum insulation panel 100 has four corners, with the lower left and lower right corners forming one group, and the upper left and upper right corners forming another group. The outer bag 20 is first folded along the side wall of the core material 10 to form four corresponding first folded edge units 31. The lower left and lower right corners are first folded against the left and right side walls of the core material 10 respectively, and then folded towards the top surface of the core material 10 to form two corresponding corner units 32. The lower left and lower right corners are based on the same second edge 222 (i.e., Figure 4 The second edge 222 (located on the front side of the core material 10) is folded towards the top surface of the core material 10 to form a second folded edge unit 33. The upper left and upper right corners are respectively folded against the left and right side walls of the core material 10 towards the top surface of the core material 10 to form two corresponding corner units 32. The upper left and upper right corners are based on the same second edge 222 (i.e., Figure 4 The second edge 222, located on the rear side of the core material 10, is folded towards the top surface of the core material 10 to form another second folded edge unit 33. This achieves the wrapping of the outline of the core material 10.
[0049] A second aspect of this utility model also provides an insulated box having the vacuum insulation panel 100 as described above. Through the above methods, the gaps in the box body can be improved, reducing the loss of heat or cold during use.
[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
