Description

Technical Field

[0001] This invention relates to a packaging structure, and more specifically, to a hook-shaped retainer, a packaging device, and a packaging method including the packaging device and the hook-shaped retainer. Background Technology

[0002] With the changing lifestyles of modern society and the rapid development of the logistics industry, many goods are traded through logistics, such as electronic products, chemical products, pharmaceutical products, ceramics, glass and other daily necessities. During the storage or transportation of these goods, it is inevitable that they will be squeezed, collided or dropped, resulting in product damage or deformation and causing losses to people. In particular, the economic losses caused by the damage or deformation of high-value items are even greater.

[0003] To protect products, packaging boxes and other materials are used before storage or transportation to provide cushioning and achieve protection. Commonly used packaging boxes include cardboard boxes and inflatable bags. Traditional cardboard boxes do not provide adequate cushioning and offer insufficient protection. For example, before transporting laptops, they are often wrapped in multiple layers of foam and flexible plastic before being placed in a box. While this traditional packaging method does achieve good drop and impact resistance, it undoubtedly increases transportation costs and is extremely inconvenient, wasting time, reducing efficiency, and increasing labor costs, thus failing to meet the needs of modern transportation. Furthermore, because both boxes and cushioning materials like foam are used, a large amount of these materials are discarded after delivery, burdening users and harming the environment.

[0004] Currently, for larger items to be packaged, such as displays or main units, especially large, flat displays, polystyrene foam (EPS) is commonly used for packaging. This serves two purposes: firstly, it protects the display; secondly, the regular shape and flat structure of the EPS packaging boxes facilitate logistics and transportation. Furthermore, the regular shape and structure reduce the overall size of the packaged items and the packaging box, thus increasing the quantity of items to be packaged in a single shipment and reducing transportation costs.

[0005] like Figure 1 and Figure 2The image shows a packaging device for a display screen in the prior art. In this packaging device, the display screen is packaged with multiple polystyrene foams. A polystyrene foam is provided on the top, bottom, left side, right side, front, and back of the display screen, thereby packaging the six sides of the display screen with six polyethylene foams.

[0006] As shown in the figure, there are also some problems when using polystyrene foam boxes to package the display screen or host. First, there are gaps between the multiple polystyrene foam pieces, especially the front of the display screen, which is not completely covered by the polystyrene foam. Since the front of the display screen 201 is a liquid crystal display, it is fragile and easily scratched. Therefore, packaging the display screen with polystyrene foam often cannot provide complete protection, and the front of the display screen is still easily broken or scratched during transportation. For example, the product inside the packaging box cannot be seen directly. Therefore, during inspection, the appearance of the display screen cannot be visually inspected. Instead, it is necessary to remove the polystyrene foam pieces one by one to inspect the appearance of the display screen.

[0007] Furthermore, because polystyrene foam is compressed into packaging boxes for product packaging, while these boxes are relatively thick and sturdy, their cushioning performance is not high, and their surface smoothness is relatively poor. Therefore, when packaging fragile glass products or relatively large flat products, such as display screens, using polystyrene foam boxes can easily lead to problems such as screen breakage or scratches.

[0008] Furthermore, since the back of a display screen generally has a certain thickness, and the thickness of different brands and models of display screens varies, existing packaging devices for such displays are either not universally applicable or cannot provide adequate protection.

[0009] Therefore, those skilled in the art need to invent a new technical solution to solve the problems existing in at least one of the prior art. Summary of the Invention

[0064] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0065] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0066] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0067] like Figures 3 to 13 As shown, the present invention mainly provides a hook-shaped retaining pad 10, a packaging device 300, and a packaging method, wherein the hook-shaped retaining pad 10 is used to provide air cushion protection for a display screen 200 and its accessories 201, and the packaging device 300 is used to package the hook-shaped retaining pad 10 and the display screen 200.

[0068] like Figures 3 to 6B As shown, in the first embodiment of the hook-shaped baffle 10 of the present invention, the hook-shaped baffle 10 includes a hook pad portion 11, wherein the hook pad portion 11 includes a long side 111 and a short side 112 and forms a generally hook-shaped baffle 10. The hook pad portion 11 of the hook-shaped baffle 10 has a first receiving cavity 110, and each of its upper and lower ends has an opening 1101, so that the display screen 200 can be placed in the first receiving cavity 110 through the opening 1101 and the front side 201 of the display screen 200 is in contact with the long side 111 of the hook pad portion 11, and the back side 202 of the display screen 200 is partially in contact with the short side 112 of the hook pad portion 11, thereby providing an air cushioning effect for the display screen 200.

[0069] In detail, the hook pad portion 11 further includes a folded edge 113, which is located between the long side 111 and the short side 112 and at the bottom 206 of the hook-shaped retaining pad 10 formed by the hook pad portion 11, so that the left side 203, right side 204 or top 205 of the display screen 200 fits against the folded edge 113 of the hook-shaped retaining pad 10.

[0070] Further, the folded edge 113 includes a first folded edge 1131 and a second folded edge 1132, wherein the first folded edge 1131 is adjacent to the long side 111, and the second folded edge 1132 is adjacent to the short side 112. In the first embodiment of the present invention, the first folded edge 1131 and the second folded edge 1132 have the same length.

[0071] The hook-shaped retainer 10 further includes a folded portion 12, which extends from the folded edge 113 of the hook-shaped retainer 11. The hook-shaped retainer 10 is partially heat-sealed to form the hook-shaped retainer 11 and the folded portion 12, wherein the hook-shaped retainer 11 and the folded portion 12 are in communication with each other. The folded portion 12 has a second receiving cavity 120 for covering the accessory 210 of the display screen 200, such as wires, plugs, etc.

[0072] It should be emphasized that the long side 111, the short side 112, the first folded edge 1131 and the second folded edge 1132 of the hook pad portion 11 of the hook-shaped pad 10 are interconnected, the hook pad portion 11 and the folded portion 12 are interconnected, and the triangular structures in the folded portion 12 are interconnected.

[0073] In other words, the parts of the hook-shaped pad 10 are interconnected, so that the hook-shaped pad 10 can be inflated and formed in one step.

[0074] The folding part 12 has a triangular structure, thereby covering the display screen accessory 210.

[0075] In addition, those skilled in the art can adjust the shape of the folding part 12 according to the actual shape of the display screen 200, such as setting the folding part 12 as a quadrilateral or hexagon. As long as the same or similar technical solutions are adopted on the basis of the above disclosure of the present invention, the same or similar technical problems are solved, and the same or similar technical effects are achieved, they all fall within the protection scope of the present invention. The specific embodiments of the present invention are not limited thereto.

[0076] It is worth noting that the width of the folded portion 12 is the same as the width of the hook pad portion 11, so that the width of the first receiving cavity 110 formed is the same as the width of the second receiving cavity 120, thereby making the overall width of the hook-shaped retaining pad 10 consistent.

[0077] Furthermore, in the first embodiment of the hook-shaped baffle 10 of the present invention, the long side 111 and the short side 112 are independent of each other, and the hook-shaped baffle 10 is made of a flexible material. Therefore, the long side 111 and the short side 112 can rotate relative to each other, thereby changing the distance between the long side 111 and the short side 112 so that the display screen 200 can be covered by the hook-shaped baffle 10.

[0078] Furthermore, in the first embodiment of the hook-shaped retaining pad 10 of the present invention, the first portion of the folded edge 1131 and the second portion of the folded edge 1132 have the same length, so that the center of gravity of the display screen 200 is located between the first portion of the folded edge 1131 and the second portion of the folded edge 1132, so that when the display screen 200 is placed in the first receiving cavity 110, the second portion of the folded edge 1132 and the short side 112 can be easily bent to cover at least a portion of the back surface 202 of the display screen 200.

[0079] Preferably, the length ranges of the first folded edge 1131 and the second folded edge 1132 are respectively implemented such that the length range of the short side 112 is 50-200mm.

[0080] Preferably, in the first embodiment of the hook-shaped pad 10 of the present invention, the length of the long side 111 of the hook pad portion 11 is in the range of 500-1200mm, and the corresponding display screen 200 is in the range of 50 inches to 100 inches.

[0081] like Figure 3 As shown, in the first embodiment of the hook-shaped baffle 10 of the present invention, the hook-shaped baffle 10 is an air buffer device 100, comprising one or more air buffer bodies 101, each of which is formed by a series of planar heat seals of a gas buffer material. The gas buffer material includes a first gas storage membrane 1011 and a second gas storage membrane 1012, and a gas storage chamber 1010 formed between the first gas storage membrane 1011 and the second gas storage membrane 1012, the gas storage chamber being adapted to be filled with a certain amount of gas.

[0082] When the gas storage chamber 1010 formed by the gas buffer material is not filled with gas, the first gas storage membrane 1011 and the second gas storage membrane 1012 of the gas buffer material are close to each other, and the gas buffer material is in a planar state. When the gas storage chamber 1010 of the gas buffer material is filled with an appropriate amount of gas, the first gas storage membrane 1011 and the second gas storage membrane 1012 separate from each other. With the gas stored between the first gas storage membrane 1011 and the second gas storage membrane 1012, the air buffer 101 has a buffering and protective function.

[0083] The air buffer 101 further has an inflation channel 1013 and at least one inflation valve 1014. The inflation channel 1013 connects the gas storage chamber 1010 and the external environment, allowing external gas to enter the gas storage chamber 1010 through the inflation channel and the inflation valve 1014, thereby enabling the air buffer 101 to play a buffering and protective role.

[0084] Furthermore, in the first embodiment of the hook-shaped baffle 10 of the present invention, the inflation valve 1014 is a self-adhesive membrane inflation valve 1014, that is, after the gas is filled into the gas storage chamber 1010 through the inflation channel 1013 and the inflation valve 1014, the inflation valve 1014 can automatically close the gas storage chamber 1010, thereby preventing the gas in the gas storage chamber 1010 from escaping through the inflation valve 1014 and the inflation channel 1013 after the inflation of the air buffer 101 is stopped.

[0085] Preferably, in the hook-shaped baffle 10 of the present invention, the diameter D of the air column after the air buffer 101 is inflated ranges from 20 to 100 mm. The display screen 200 ranges from 50 inches to 100 inches.

[0086] The gas buffer material further includes a planar molding unit 1015, which is used to heat-seal the first gas storage film 1011 and the second gas storage film 1012 together, thereby forming the gas storage chamber 1010 and the inflation channel 1013 between the first gas storage film 1011 and the second gas storage film 1012, and enabling the gas filled into the gas storage chamber 1010 to be retained in the gas storage chamber 1010, thereby enabling the air buffer 101 to provide buffer protection.

[0087] It is worth noting that in the first embodiment of the hook-shaped retainer 10 of the present invention, the planar molding unit 1015 further includes at least one separating heat-sealing line 10151. The separating heat-sealing line 10151 is disposed on the first part folded edge 1131, the second part folded edge 1132 in the hook pad portion 11 and the air buffer body 101 in the folded portion 12, so that the air column diameters of the first part folded edge 1131, the second part folded edge 1132 in the hook pad portion 11 and the air buffer body 101 in the folded portion 12 are divided into smaller than the air column diameter d of the air buffer body 101 in the long side 111 and the short side 112 in the hook pad portion 11, so that the short side 112 in the first buffer body can more easily and automatically form the hook-shaped retainer 10 after inflation.

[0088] Furthermore, the air column diameter d of any of the air cushions 101 in the first folded edge 1131, the second folded edge 1132, and the folded portion 12 is approximately half the air column diameter D of any of the air cushions 101 in the long side 111 and the short side 112 of the hook pad portion 11.

[0089] Furthermore, the gas buffer material further includes a three-dimensional molding unit 1016, which is used to mold the gas storage chamber 1010 to form the hook-shaped baffle 10, and the three-dimensional molding unit 1016 does not block the gas continuity of the gas storage chamber 1010. In other words, the gas between the gas storage chambers 1010 that are heat-sealed and separated by the three-dimensional molding unit 1016 is interconnected, thereby allowing the hook-shaped baffle 10 to be inflated and formed in one step.

[0090] In detail, the three-dimensional molding unit 1016 includes at least one main dividing line 10161, which is heat-sealed between the hook pad portion 11 and the fold portion 12 to separate the hook pad portion 11 and the fold portion 12.

[0091] The three-dimensional molding unit 1016 further includes a first dividing line 10162 and a second dividing line 10163, wherein the first dividing line 10162 is located between the first partial folded edge 1131 and the long side 111, and the second dividing line 10163 is located between the second partial folded edge 1132 and the short side 112, thereby forming the hook-shaped retaining pad 10 by heat sealing the hook pad portion 11 with the main dividing line 10161, the first dividing line 10162 and the second dividing line 10163.

[0092] Similarly, in the first embodiment of the hook-shaped retaining pad 10 of the present invention, the three-dimensional sealing unit 1016 further includes a third dividing line 10164, a fourth dividing line 10165, a fifth dividing line 10166, and a sixth dividing line 10167, wherein the third dividing line 10164, the fourth dividing line 10165, the fifth dividing line 10166, and the sixth dividing line 10167 are respectively disposed on the folded portion 12, wherein the third dividing line 10164 and the fourth dividing line 10165 are close to each other, the fifth dividing line 10166 and the sixth dividing line 10167 are close to each other, and the third dividing line 10164 and the fourth dividing line 10165 are respectively disposed opposite to the fifth dividing line 10166 and the sixth dividing line 10167, so that the folded portion 12 forms a generally triangular structure.

[0093] like Figure 8As shown, as a variation of the first embodiment of the present invention, the folding part 12 can also be configured as a pentagonal structure, simply by adjusting the relative positions of the third dividing line 10164, the fourth dividing line 10165, the fifth dividing line 10166 and the sixth dividing line 10167.

[0094] Furthermore, by adjusting the distance between the third dividing line 10164 and the fourth dividing line 10165, and the distance between the fifth dividing line 10166 and the sixth dividing line 10167, and making the distance between the third dividing line 10164 and the fourth dividing line 10165 equal to the distance between the fifth dividing line 10166 and the sixth dividing line 10167, the folding portion 12 can be made into a pentagonal structure, thereby forming the second receiving cavity 120 to house the display screen 200 accessory 210.

[0095] In addition, those skilled in the art can also determine the specific structure of the folding portion 12 and the air column diameter of each air buffer 101 in the hook pad portion 11 and the folding portion 12 based on the specific shape and structure of the display screen accessory 210; all of these fall within the protection scope of this invention. In other words, as long as a technical solution that is the same as or similar to this invention is adopted on the basis of the above disclosure of this invention, solves the same as or similar technical problems as this invention, and achieves the same as or similar technical effects as this invention, it falls within the protection scope of this invention.

[0096] Preferably, in the hook-shaped baffle 10 of the present invention, the overall size of the folding part 12 is in the range of 50-150mm, and the size of the corresponding display screen 200 is in the range of 50 inches-100 inches.

[0097] Furthermore, in the first embodiment of the hook-shaped baffle 10 of the present invention, the air buffer device 100 in the hook-shaped baffle 10 includes a plurality of continuous air buffer bodies 101, and each air buffer body 101 is interconnected through the inflation channel 1013. Adjacent air buffer bodies 101 are connected by a breakpoint connecting line 102, so that any two adjacent air buffer bodies 101 can be easily separated, so that the width of the hook-shaped baffle 10 can be freely defined.

[0098] In this embodiment of the invention, the planar molding unit 1015 includes a plurality of chamber-separating heat-sealing lines 10150, which heat-seal the first gas storage film 1011 and the second gas storage film 1012. A gap region 1017 is formed between two adjacent gas storage chambers 1010, and the gap region 1017 is formed between two chamber-separating heat-sealing lines 10150. The breakpoint connecting line 102 is disposed in the gap region 1017 and located between two chamber-separating heat-sealing lines 10150, thereby reducing the width of each chamber-separating heat-sealing line 10150 and facilitating the removal of each hook-shaped retainer 10 from the continuous air buffer 101.

[0099] In other variations, only one heat-sealing line 10150 may be formed between the two gas storage chambers 1010, and the breakpoint connection line 102 is formed on the heat-sealing line 10150.

[0100] In other words, the air buffer device 100 of the present invention includes a plurality of continuous air buffer bodies 101. The plurality of air buffer bodies 101 can be integrally heat-sealed and inflated in one go, thereby forming a large hook-shaped baffle 10 in the entire air buffer device 100. Then, the width of a single hook-shaped baffle 10 is determined according to the actual width required to cover the display screen 200. At this time, it is only necessary to tear the air buffer body 101 apart from the breakpoint connecting line 102 between two adjacent air buffer bodies 101.

[0101] In other words, in the first embodiment of the hook-shaped baffle 10 of the present invention, the width of the hook-shaped baffle 10 can be adjusted according to the actual required width of the display screen 200, so that the hook-shaped baffle 10 can provide buffer protection for the display screen 200 of different sizes and models, thus further improving the applicability and flexibility of the hook-shaped baffle 10 of the present invention.

[0102] It is worth mentioning that the width of the hook-shaped baffle 10 can also be fixed. The breakpoint connecting line 102 is disposed between some of the air buffer bodies 101 in the continuous air buffer body 101, such as... Figure 6A and 6B As shown. The continuous air buffer 101 can be automatically inflated by an automatic inflator, that is, the air nozzle of the automatic inflator inflates the air passage 1013, thereby entering each of the gas storage chambers 1010. Then, each of the hook-shaped baffles 10 is torn off along the breakpoint connection line 102.

[0103] In use, the two hook-shaped baffles 10 are placed on both sides of the display screen 200, with the display screen 200 located within the two first receiving cavities 110 formed by the two hook-shaped baffles 10. The long sides 111 of the hook pad portions 11 of the two hook-shaped baffles 10 are respectively attached to the front 201 of the display screen 200, and the short sides 112 of the hook pad portions 11 are respectively attached to the back 202 of the display screen 200. This causes the folded edges 113 and folded portions 12 of the hook pad portions 11 to be located on the left side 203 or right side 204 of the display screen 200, thereby providing cushioning protection for the front 201, back 202, and both sides of the display screen 200. The display screen accessory 210 is then placed in the second receiving cavity 120 formed by the folded portions 12, thus providing overall cushioning protection for the display screen 200.

[0104] like Figure 7 As shown, in a modified embodiment of the first embodiment of the hook-shaped baffle 10 of the present invention, since a typical display screen 200, such as a television screen, has a raised portion on its back side, the length of the second portion of the folded edge 1132 is implemented to be longer than the length of the first portion of the folded edge 1131. Thus, the short side 112 is not easy to curl up, but naturally extends inward to form a hook shape. Therefore, after the display screen 200 is placed in the first receiving cavity 110, the second portion of the folded edge 1132 and the short side 112 can automatically cover at least part of the back side 202 and the raised portion of the display screen 200.

[0105] like Figures 9 to 12As shown, the present invention further provides a packaging device 300 for packaging the hook-shaped retaining pads 10 and the display screen 200. The packaging device 300 includes a first cushioning element 20, a second cushioning element 30, two hook-shaped retaining pads 10, and a packaging shell 40. A bottom 206 and a top 205 of the display screen 200 can be respectively covered by the first cushioning element 20 and the second cushioning element 30. The two hook-shaped retaining pads 10 are respectively disposed on the left and right sides of the display screen 200 and can accommodate the front 201 of the display screen 200 within the two hook-shaped retaining pads. The two first receiving cavities 110 formed by the pad 10 allow the front 201 of the display screen 200 to be completely covered by the first buffer element 20, the second buffer element 30, and the two hook-shaped retaining pads 10. The packaging shell 40 has a receiving space 401, in which the first buffer element 20, the second buffer element 30, the two hook-shaped retaining pads 10, and the display screen 200 can be placed, thereby forming an integral structure with the display screen 200, the first buffer element 20, the second buffer element 30, and the two hook-shaped retaining pads 10.

[0106] In detail, such as Figure 9 and Figure 10 As shown, the first buffer element 20 has a first receiving groove 201, and the second buffer element 30 has a second receiving groove 301, wherein the bottom 206 and the top 205 of the display screen 200 can be respectively received in the first receiving groove 201 of the first buffer element 20 and the second receiving groove 301 of the second buffer element 30, thereby providing buffer protection for the bottom 206 and the top 205 of the display screen 200 respectively.

[0107] Preferably, the width of the first receiving groove 201 is the same as or slightly longer than the width of the bottom 206 of the display screen 200, and the length of the first receiving groove 201 is the same as or slightly longer than the length of the bottom 206 of the display screen 200, so that the bottom 206 of the display screen 200 can be perfectly accommodated in the first receiving groove 201. In other words, the size of the first receiving groove 201 can form an interference fit or a transition fit with the size of the bottom 206 of the display screen 200.

[0108] Similarly, the width of the second receiving groove 301 is the same as or slightly longer than the width of the top 205 of the display screen 200, and the length of the second receiving groove 301 is the same as or slightly longer than the length of the top 205 of the display screen 200, so that the top 205 of the display screen 200 can be perfectly accommodated in the second receiving groove 301. In other words, the size of the second receiving groove 301 can form an interference fit or a transition fit with the size of the top 205 of the display screen 200.

[0109] Furthermore, in the first embodiment of the present invention, the display screen 200 is implemented as a regular rectangle or square, so the bottom 206 and the top 205 of the display screen 200 are the same size, thereby making the shape and size of the first buffer element 20 and the second buffer element 30 the same, and the shape and size of the first receiving groove 201 and the second receiving groove 301 formed are also the same.

[0110] Therefore, the first buffer element 20 and the second buffer element 30 can not only be used in combination, but also the manufacturing steps and methods of the first buffer element 20 and the second buffer element 30 are the same, thereby reducing the manufacturing cost of the first buffer element 20 and the second buffer element 30, and reducing the types of parts of the packaging device 300, thereby reducing the production and use cost of the packaging device 300.

[0111] It should be emphasized that the depths of the first receiving slot 201 and the second receiving slot 301 are each less than half the width of the display screen 200, so that when the top 205 and bottom 206 of the display screen 200 are respectively received in the first receiving slot 201 and the second receiving slot 301, the first buffer element 20 and the second buffer element 30 will not completely cover the display screen 200.

[0112] Preferably, in the first embodiment of the packaging device 300 of the present invention, the first buffer element 20 and the second buffer element 30 are made of polystyrene foam. Since polystyrene foam has the characteristics of being lightweight and having good cushioning effect, the first buffer element 20 and the second buffer element 30 can provide cushioning protection for the display screen 200 without excessively increasing the overall weight of the packaging device 300.

[0113] In addition, those skilled in the art can also select other materials to make the first buffer element 20 and / or the second buffer element 30 according to the actual situation, including but not limited to polyethylene, polystyrene, polyvinyl chloride, etc. In other words, as long as the same or similar technical solutions are adopted on the basis of the above disclosure of the present invention, the same or similar technical problems are solved, and the same or similar technical effects are achieved, they all fall within the protection scope of the present invention, and the specific embodiments of the present invention are not limited thereto.

[0114] During packaging, the bottom 206 of the display screen 200 is placed in the first receiving groove 201 of the first buffer element 20, and the second buffer element 30 is placed over the top 205 of the display screen 200, so that the top 205 of the display screen 200 is accommodated in the second receiving groove 301 of the second buffer element 30. Two hook-shaped baffles 10 are respectively placed on both sides of the display screen 200, placing the display screen 200 within the two first receiving cavities 110 formed by the two hook-shaped baffles 10. The long sides 111 of the hook pad portions 11 of the two hook-shaped baffles 10 are respectively attached to the front side 201 of the display screen 200, and the short sides 112 of the hook pad portions 11 are respectively attached to the back side 202 of the display screen 200. This causes the folded edges 113 and the folded portions 12 of the hook pad portions 11 to be located on the left side 203 or right side 204 of the display screen 200, thereby providing cushioning protection for the front side 201, back side 202, and both sides of the display screen 200. The display screen accessory 210 is placed in the second receiving cavity 120 formed by the folded portions 12. Finally, the first buffer element 20, the second buffer element 30, and the two hook-shaped baffles 10, together with the covered display screen 200, are placed in the receiving space 401 of the packaging shell 40, thereby providing overall buffer protection for the display screen 200.

[0115] In addition, those skilled in the art can modify the specific structure of the packaging device 300 according to actual conditions, for example, by setting the structure of the hook-shaped retaining pad 10 in the packaging device 300 to different sizes. Therefore, in the modified embodiment of the packaging device 300, the packaging device 300 does not include the second cushioning element 30 covering the top 205 of the display screen 200, because in this modified embodiment of the packaging device 300, the top 205 of the display screen 200 is covered by the hook pad portion 11 of the hook-shaped retaining pad 10 and is cushioned and protected by the hook pad portion 11 and the folded portion 12.

[0116] Accordingly, those skilled in the art can further modify the specific structure of the packaging device 300 according to the actual situation. For example, the hook-shaped baffle 10 in the packaging device 300 can be configured to have the same structure and packaging method as the hook-shaped baffle 10 in the third embodiment described above. Therefore, in this further modified embodiment, the packaging device 300 also does not include the second cushioning element 30 covering the top 205 of the display screen 200, because in this further modified embodiment of the packaging device 300, the top 205 of the display screen 200 is covered by the hook pad portion 11 of the hook-shaped baffle 10 and is cushioned and protected by the hook pad portion 11 and the fold portion 12.

[0117] like Figure 13 As shown, the present invention further provides a packaging method for a packaging device 300, the packaging method comprising the steps of:

[0118] 1001: The bottom 206 of the display screen 200 is placed in the first receiving groove 201 of the first buffer element 20, thereby providing buffer protection for the bottom 206 of the display screen 200.

[0120] 1003: Two hook-shaped baffles 10 are respectively placed around the left and right sides of the display screen 200, so that the display screen 200 is covered by the two first receiving cavities 110 of the two hook-shaped baffles 10. The long sides 111 of the hook pad portions 11 of the two hook-shaped baffles 10 are respectively located on the front 201 of the display screen 200, and the short sides 112 of the hook pad portions 11 are respectively located on the back 202 of the display screen 200. The folded portions 12 of the two hook-shaped baffles 10 are respectively located on the left and right sides of the display screen 200, thereby providing air cushioning protection for the front 201, back 202, and left and right sides of the display screen 200; and

[0121] 1004: The first buffer element 20, the second buffer element 30, the two hook-shaped baffles 10, and the display screen 200 and its accessories 210 are enclosed in the receiving space 401 of the packaging shell 40.

[0122] In step 1003, the structure and packaging method of the hook-shaped retaining pad 10 are the same as those of the first embodiment of the hook-shaped retaining pad 10 in this invention.

[0123] Furthermore, those skilled in the art can also select different hook-shaped pads to package the display screen according to actual conditions. The packaging method of the packaging device 300 of the present invention also varies depending on the selection of different hook-shaped pads 10. As long as the same or similar technical solutions are adopted on the basis of the above disclosure of the present invention, the same or similar technical problems are solved, and the same or similar technical effects are achieved, they all fall within the protection scope of the present invention. The specific embodiments of the present invention are not limited thereto.
