Description

Technical Field

[0001] This application relates to the field of product packaging technology, and in particular to a folding packaging structure and a combination packaging structure. Background Technology

[0002] As the international community places increasing emphasis on environmental protection, more and more products are gradually abandoning plastic bags for packaging and instead adopting more environmentally friendly materials, such as corrugated cardboard boxes.

[0003] Currently, packaging boxes typically include an inner liner. The product is placed between the inner wall of the box and the liner, relying on the liner to withstand external pressure on the box, thus effectively protecting the product stored inside. However, in existing packaging boxes, the inner liner is usually made of a separate material or is separately die-cut, which significantly increases the material cost and labor assembly cost of the packaging box. Utility Model Content

[0004] Therefore, it is necessary to address the problem that the use of independent materials or independent die-cutting in the inner lining of existing cardboard packaging boxes leads to a significant increase in the material cost and labor assembly cost of the packaging boxes. A folding packaging structure that can solve the above problems and a combined packaging structure including the folding packaging structure are needed.

[0005] According to one aspect of this application, a folding packaging structure is provided, comprising:

[0006] The main body includes an integrally connected base plate and several surrounding panels, all of which are foldable relative to the base plate so that the base plate and each of the surrounding panels can be assembled into a packaging box with a receiving cavity;

[0007] The inner lining panel is integrally connected to one side of one of the surrounding panels. The inner lining panel is foldable relative to the main body (210) toward the receiving cavity when the base plate and each of the surrounding panels form the packaging box, so as to confine it within the receiving cavity.

[0008] In one embodiment, the inner lining plate includes an inner substrate plate and a plurality of inner lining side plates surrounding the inner substrate plate. The mesh is formed on the inner substrate plate, which has a plurality of stretchable and deformable mesh holes. One of the inner lining side plates is integrally connected to one of the surrounding plates of the main body. When the inner lining plate is confined within the receiving cavity, all the inner lining side plates are in close contact with the inner wall of the receiving cavity.

[0009] In one embodiment, each of the enclosure panels includes a front panel, a rear panel, and two side panels; when each of the enclosure panels is unfolded relative to the bottom plate, the front panel and the rear panel are integrally connected to opposite sides of the bottom plate along a first direction, the two side panels are integrally connected to opposite sides of the bottom plate or the rear panel along a second direction, the second direction being perpendicular to the first direction, and the inner lining panel is integrally connected to the side of the front panel away from the bottom plate.

[0010] In one embodiment, each of the side panels includes an inner side panel, an outer side panel, and a bottom side panel, wherein the outer side panel is integrally connected to one side of the rear panel along the second direction; when each of the surrounding panels is unfolded relative to the bottom panel, the inner side panel is integrally connected to one side of the outer side panel along the first direction, and the bottom side panel is integrally connected to the other side of the outer side panel along the first direction.

[0011] When the surrounding panels and the bottom plate form the packaging box, the side bottom plate can be folded relative to the side outer plate and attached to the bottom plate, and the side inner plate can be folded relative to the side outer plate and connected to the side bottom plate, so that the side inner plate and the side outer plate are parallel to each other and form a slot.

[0012] In one embodiment, the inner side panel has a positioning piece on the side for connecting with the bottom side panel, and the bottom side panel has a positioning groove near the outer side panel. When the surrounding panels and the bottom panel form the packaging box, the positioning piece can be inserted into the positioning groove so that the inner side panel is connected to the bottom side panel.

[0013] In one embodiment, the front panel is integrally connected with a first tongue on each of its opposite sides along the second direction; when the surrounding panels and the bottom plate form the packaging box, the first tongue can be folded relative to the front panel so that the first tongue can be inserted into the slot.

[0014] In one embodiment, a top plate is integrally connected to the side of the rear plate away from the bottom plate. The top plate is foldable relative to the rear plate so that when the side panels and the bottom plate form the packaging box, the top plate can cover the inner lining.

[0015] In one embodiment, the top plate is integrally connected to two opposite sides along the second direction with second tongues, the second tongues being foldable relative to the top plate so that when the top plate covers the inner lining plate, the second tongues can be inserted into the gap formed between the inner lining side plate and the surrounding plate.

[0016] In one embodiment, a front cover plate is integrally connected to the side of the top plate away from the rear plate. The front cover plate is foldable relative to the top plate so that when the top plate covers the inner liner, the front cover plate can be attached to the front plate.

[0017] In one embodiment, when the side panel and the bottom plate form the packaging box, each side panel can form a first slot; the front panel is integrally connected with a third tongue on each of the opposite sides along the second direction, and the third tongue can be folded relative to the front panel so that when the front panel is attached to the front plate, the third tongue can be inserted into the corresponding slot.

[0018] According to another aspect of this application, a combined packaging structure is provided, comprising:

[0019] Outer box;

[0020] As described in any of the above embodiments, when the folding packaging structure is folded into the packaging box, the packaging box can be stored in the outer box.

[0021] In one embodiment, the combined packaging structure further includes at least two cushioning structures that can be housed within the outer box, all of the cushioning structures being arranged in pairs, wherein when the packaging box is housed within the outer box, the packaging box is held between the pairs of cushioning structures;

[0022] And / or, the combined packaging structure further includes corner protectors that can be housed within the outer box, wherein when the packaging box is housed within the outer box, the ends of the packaging box are inserted into the corner protectors.

[0023] In one embodiment, the corner protector structure has two parts, which are arranged in pairs with a distance between them. When the combined packaging structure includes the corner protector structure and the cushioning structure, the distance between the two corner protector structures arranged in pairs is equal to the dimension of the cushioning structure along its own length.

[0024] The aforementioned folding packaging structure and combined packaging structure including the folding packaging structure, by integrally connecting the inner liner to one of the side panels of the main body, allows the inner liner to fold relative to the main body and confine itself within the cavity when the bottom plate of the main body and the side panel form a packaging box with a receiving cavity. This encloses the product in the closed space formed between the inner liner and the bottom wall of the receiving cavity, thus integrating the connection and materials of the inner liner and the main body. This eliminates the need for separate materials and die-cutting, thereby saving material costs and labor assembly costs for the folding packaging structure and combined packaging structure, and providing a better fixing effect for products of different shapes.

[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0036] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0039] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0040] One embodiment of this application provides a folding packaging structure that can be formed by folding a cardboard sheet. This structure is used to store products and protect them during handling or transportation to prevent damage.

[0041] The structure of the folding packaging structure in this application is described below. This embodiment is only used as an example and does not limit the technical scope of this application. It is understood that in other embodiments, the packaging structure of this application can be used to package any product, and no limitation is made here.

[0042] See Figures 1 to 3 , Figure 1 This is a top view of a folding packaging structure 200 according to an embodiment of the present application in its unfolded state. Figure 2 and Figure 3 A schematic diagram of the folded packaging structure 200 of this embodiment in its folded state is shown. An embodiment of the folded packaging structure 200 provided in this application includes a main body 210 and an inner liner 220. The main body 210 includes an integrally connected base plate 211 and a plurality of surrounding plates 212. All surrounding plates 212 are foldable relative to the base plate 211, so that the base plate 211 and the surrounding plates 212 can be folded together to form a folded shape. Figure 2 and Figure 3The packaging box shown has a receiving cavity 210a, in which the product 50 can be stored. The inner liner 220 is integrally connected to one side of one of the surrounding panels 212. When the bottom plate 211 and the surrounding panels 212 form the packaging box, the inner liner 220 can be folded relative to the main body 210 towards the receiving cavity 210a to confine it within the receiving cavity 210a and close the opening of the receiving cavity 210a, thereby sealing the product 50 in the closed space formed by the inner liner 220 and the bottom wall of the receiving cavity 210a.

[0043] The inner liner 220 is used to withstand a certain amount of pressure when the packaging box is subjected to external pressure, thereby providing better protection for the product 50 placed under the inner liner 220.

[0044] Better, such as Figure 1 and Figure 3 As shown, the inner lining plate 220 has multiple stretchable and deformable mesh holes 223, each mesh hole 223 penetrating the inner lining plate 220. Preferably, all mesh holes 223 are arranged in an array. The purpose of having mesh holes 223 on the inner lining plate 220 is that when the inner lining plate 220 is subjected to pressure from above, the mesh holes 223 can play a certain buffering role, reducing the pressure on the product 50, and the mesh holes 223 can provide a good fixing effect for products 50 of different shapes.

[0045] Specifically, regarding the specific structure of the inner lining plate 220, in the embodiment shown in the figure, the inner lining plate 220 includes an inner base plate 221 and multiple inner lining side plates 222 surrounding the inner base plate 221. Mesh 223 is formed on the inner base plate 221. One of the inner lining side plates 222 is integrally connected to a surrounding plate 212 of the main body 210. As can be seen from the figure, the connection line between one of the inner lining side plates 222 and a surrounding plate 212 of the main body 210 forms a reverse folding pressure line 201, so that when the bottom plate 211 and the surrounding plate 212 form a packaging box, the inner lining plate 220 can be folded relative to the main body 210 along the reverse folding pressure line 201 in the direction closer to the receiving cavity 210a.

[0046] Thus, the connection and material integration between the inner lining panel 220 and the main body 210 eliminate the need to use separate materials and separate die-cutting processes to manufacture the inner lining panel 220, thereby saving material costs and labor assembly costs for the folding packaging structure 200.

[0047] Please continue reading. Figure 1As can be seen from the figure, the connection line between the inner liner side plate 222 and the inner liner plate 221 forms an inner liner pressure line 224. When the inner liner plate 220 is confined within the receiving cavity 210a, all the inner liner side plates 222 are tightly attached to the inner wall of the receiving cavity 210a. That is, the inner liner side plates 222 can be folded along the inner liner pressure line 224 relative to the inner liner plate 221 in a direction away from the receiving cavity 210a, so that all the inner liner side plates 222 are tightly attached to the inner wall of the receiving cavity 210a. With this arrangement, when the product is sealed under the inner liner plate 220, as the inner liner plate 220 presses the product, the mesh 223 can be stretched and deformed, thereby covering the product tightly and preventing it from moving freely, thus better fixing the product 50.

[0048] It is understandable that when the base plate 211 and each of the surrounding plates 212 form a packaging box, the inner lining side plate 222 can be attached to the surrounding plate 212 to fix the inner lining side plate 222 by using the friction between the inner lining side plate 222 and the surrounding plate 212, so as to prevent the inner lining side plate 222 from collapsing or flipping up. The inner lining side plate 222 may also have a gap with the surrounding plate 212, which is not limited here.

[0049] Please combine Figures 1 to 3 As shown, in the specific structure of the main body 210, each of the surrounding panels 212 of the main body 210 includes a front panel 2121, a rear panel 2122 and two side panels 2123. When each of the surrounding panels 212 is unfolded relative to the bottom plate 211, the front panel 2121 and the rear panel 2122 are integrally connected to the opposite sides of the bottom plate 211 along the first direction (X direction shown in the figure), and the two side panels 2123 are integrally connected to the opposite sides of the rear panel 2122 along the second direction (Y direction shown in the figure, the Y direction is perpendicular to the X direction). The inner lining panel 220 is integrally connected to the side of the front panel 2121 away from the bottom plate 211.

[0050] As can be seen from the figure, the anti-folding pressure line 201 is formed by the connecting line between the front plate 2121 and the inner lining plate 220, the connecting line between the front plate 2121 and the bottom plate 211 forms the first front pressure line 202, the connecting line between the rear plate 2122 and the bottom plate 211 forms the first rear pressure line 203, and the connecting line between the side plate 2123 and the rear plate 2122 forms the first side pressure line 204.

[0051] Thus, the front panel 2121, after being folded relative to the bottom panel 211 along the first front pressure line 202, can serve as the front side panel 212 of the packaging box. The rear panel 2122, after being folded relative to the bottom panel 211 along the first rear pressure line 203, can serve as the rear side panel 212 of the packaging box. The two side panels 2123, after the front panel 2121 is folded relative to the bottom panel 211 along the first front pressure line 202, can be folded relative to the rear panel 2122 along the first side pressure line 204, respectively, thus serving as the left and right side panels 212 of the packaging box. At this time, the front panel 2121, the rear panel 2122, and the side panels 2123 are located around the bottom panel 211, forming an upper-opening receiving cavity 210a with the bottom panel 211.

[0052] After the side panels 2123 are folded to form the two side panels 212 of the packaging box, in order to ensure that the side panels 2123 have high strength and provide better protection for the product 50 from both sides of the packaging box along the second direction, such as... Figure 1 and Figure 4 As shown, each side panel 2123 includes an inner side panel 2123a, an outer side panel 2123b, and a bottom side panel 2123c. The outer side panel 2123b is integrally connected to one side of the rear panel 2122 along the second direction. When the enclosure panel 212 is unfolded relative to the bottom panel 211, the inner side panel 2123a is integrally connected to one side of the outer side panel 2123b along the first direction (i.e., Figure 1 The upper edge of the middle outer panel 2123b), and the side bottom panel 2123c are integrally connected to the other side of the side outer panel 2123b along the first direction (i.e., Figure 1 The lower edge of the middle outer panel 2123b). The connecting line between the inner side panel 2123a and the outer side panel 2123b forms the first side panel pressure line 2123d, and the connecting line between the bottom side panel 2123c and the outer side panel 2123b forms the second side panel pressure line 2123e. The inner side panel 2123a can be folded relative to the outer side panel 2123b along the first side panel pressure line 2123d, and the bottom side panel 2123c can be folded relative to the outer side panel 2123b along the second side panel pressure line 2123e.

[0053] Thus, see Figure 5 When the side panels 212 and the bottom plate 211 form a packaging box, the outer side panel 2123b is perpendicular to the back panel 2122 and also perpendicular to the bottom plate 211. At this time, the bottom side panel 2123c can be folded relative to the outer side panel 2123b and attached to the bottom plate 211. Similarly, the inner side panel 2123a can be folded relative to the outer side panel 2123b and connected to the bottom side panel 2123c, so that the inner side panel 2123a and the outer side panel 2123b are parallel to each other and form a slot 2123f. This design allows the side panel 2123 to have two layers after folding, thus strengthening its strength. Furthermore, the slot 2123f provides a certain degree of cushioning for the product 50 placed in the receiving cavity 210a.

[0054] To ensure a secure connection between the inner side panel 2123a and the bottom side panel 2123c, in a preferred embodiment, the inner side panel 2123a has a positioning piece 2123g on the side for connection with the bottom side panel 2123c, and the bottom side panel 2123c has a positioning groove 2123h at its outer position near the outer side panel 2123b. When the surrounding panel 212 and the bottom panel 211 form a packaging box, the positioning piece 2123g can be inserted into the positioning groove 2123h to securely connect the inner side panel 2123a to the bottom side panel 2123c. It is evident that by providing the positioning piece 2123g and the positioning groove 2123h, the inner side panel 2123a and the bottom side panel 2123c can be fixed without the need for glue or other tools, thereby improving assembly efficiency and saving assembly costs.

[0055] Of course, the structure of the side plate 2123 is not limited to this. In other embodiments, the side plate 2123 can also be integrally connected to the base plate 211, and the side plate 2123 has multiple pressure lines parallel to the left and right sides of the base plate 211, so that the side plate 2123 can be folded along the multiple pressure lines to form a structure with a slot 2123f.

[0056] Please continue reading. Figure 1 After the front panel 2121 is folded relative to the bottom panel 211, in order to better secure the front panel 2121, first tongues 2124 are integrally connected to opposite sides of the front panel 2121 along the second direction. The connecting line between the first tongues 2124 and the front panel 2121 forms a second side pressure line 205. When the surrounding panels 212 and the bottom panel 211 form a packaging box, the first tongues 2124 can be folded relative to the front panel 2121 along the second side pressure line 205 so that the first tongues 2124 can be inserted into the slots 2123f. By inserting the first tongues 2124 into the slots 2123f, the two ends of the front panel 2121 along the second direction can be secured, thus preventing the front panel 2121 and the bottom panel 211 from returning from the folded state to the unfolded state.

[0057] Furthermore, such as Figures 1 to 3 As shown, in the folding packaging structure 200 provided in this application, the folding packaging structure 200 also includes a top plate 230, which is integrally connected to the side of the rear plate 2122 away from the bottom plate 211. The connection edge between the rear plate 2122 and the top plate 230 is constructed as a second rear pressure line 206. Preferably, when each of the surrounding plates 212 is unfolded relative to the bottom plate 211, the dimension of the top plate 230 along the first direction is equal to the dimension of the bottom plate 211 along the first direction. Thus, after the bottom plate 211 and each of the surrounding plates 212 form a packaging box, and after the inner lining plate 220 is folded relative to the main body 210 to form an inner lining cavity 220a, the top plate 230 can be folded relative to the rear plate 2122 along the second rear pressure line 206, so that the top plate 230 can cover the inner lining plate 220 and completely close the upper opening of the inner lining cavity 220a.

[0058] Similar to the structure of the fixed front plate 2121 described above, after the top plate 230 is folded relative to the rear plate 2122 and the opening of the inner lining cavity 220a is closed, in order to fix the top plate 230 as well and prevent the upper opening of the inner lining cavity 220a from opening after the top plate 230 and the rear plate 2122 return from the folded state to the unfolded state, the top plate 230 is integrally connected with the second tongue 240 on both opposite sides along the second direction. The connecting line between the top plate 230 and the second tongue 240 is constructed as a third side pressure line 208. The second tongue 240 can be folded relative to the top plate 230 along the third side pressure line 208 so that when the top plate 230 is covered by the inner lining plate 220, the second tongue 240 can be inserted into the gap formed between the inner lining side plate 222 and the side plate 2123, thereby fixing the top plate 230 and preventing the top plate 230 from flipping upward in the direction away from the receiving cavity 210a.

[0059] Furthermore, based on the above embodiment, the top plate 230 is integrally connected to the side away from the rear plate 2122 with a front cover plate 250. The connection line between the rear plate 2122 and the front cover plate 250 is constructed as a second front pressure line 207. The front cover plate 250 can be folded relative to the top plate 230 along the second front pressure line 207 so that when the top plate 230 covers the inner liner plate 220, the front cover plate 250 can be attached to the front plate 2121, thereby better sealing the inner liner cavity 220a.

[0060] Similarly, to secure the front panel 250 and prevent it from reverting from a folded to an unfolded state with the top panel 230, the front panel 250 is integrally connected to two opposite sides along the second direction with third tongues 260. The connection line between the third tongues 260 and the front panel 250 is constructed as a fourth side pressure line 209, allowing the third tongues 260 to fold relative to the front panel 250 along the fourth side pressure line 209. Therefore, when the front panel 250 is attached to the front panel 2121, the third tongues 260 can be inserted into the slots 2123f formed by the corresponding side panels 2123. This secures the front panel 250, ensuring it remains firmly attached to the front panel 2121.

[0061] It is understandable that, while keeping the overall structure of the folding packaging structure 200 unchanged, changing the size of each panel in the folding packaging structure 200 can change the length, width, and height of the packaging box, and there is no specific limitation.

[0062] The above Figure 1 The illustrated embodiment provides a folding packaging structure 200, which, when folded, forms... Figure 2 and Figure 3 When using the packaging box shown, combine Figures 1 to 3 As shown, the folding steps are as follows:

[0063] The first step is to fold the two side panels 2123 and the outer side panels 2123b along the first side pressure line 204 relative to the back panel 2122 by 90°.

[0064] The second step is to fold the bottom side plates 2123c of the two side plates 2123 at 90° relative to the outer side plate 2123b along the second side plate pressing line 2123e.

[0065] The third step is to fold the inner side plates 2123a of the two side plates 2123 relative to the outer side plate 2123b along the first side plate pressure line 2123d; so that the inner side plate 2123a and the outer side plate 2123b form a slot 2123f, and at the same time insert the positioning piece 2123g on the inner side plate 2123a into the positioning groove 2123h of the bottom side plate 2123c, so that the inner side plate 2123a is fixedly connected to the bottom side plate 2123c;

[0066] Fourth step, fold the back plate 2122 90° relative to the bottom plate 211 along the first back pressure line 203. At this time, the back plate 2122 and the side outer plate 2123b can be perpendicular to the bottom plate 211, and the side bottom plate 2123c can be attached to the bottom plate 211.

[0067] Fifth step, fold the front plate 2121 90° relative to the bottom plate 211 along the first front pressure line 202, then fold the first tongue 2124 connected to the front plate 2121 90° relative to the front plate 2121 along the second side pressure line 205, and insert the first tongue 2124 into the slot 2123f formed by the side plate 2123.

[0068] The sixth step is to fold the inner liner 220 along the reverse folding line 201 toward the direction of the receiving cavity 210a, so that the inner liner 220 is confined within the receiving cavity 210a. It should be noted that before folding the inner liner 220, the product 50 needs to be placed in an appropriate position to ensure that the area of ​​the inner liner 220 with the mesh 223 can cover the product 50.

[0069] Step 7: Fold the inner lining side plate 222 of the inner lining plate 220 90° away from the inner lining bottom plate 221 along the inner lining pressure line 224 so that the inner lining plate 220 forms the inner lining cavity 220a, thereby enabling the inner lining plate 220 to press the product 50 and play a role in limiting and fixing the product 50.

[0070] Step 8: Fold the top plate 230 90° relative to the rear plate 2122 along the second rear pressure line 206 so that the top plate 230 closes the upper opening of the inner liner cavity 220a.

[0071] Step 9: Fold the second tongue 240 along the third side pressure line 208 relative to the top plate 230, so that the second tongue 240 is inserted into the gap formed between the inner lining side plate 222 and the side plate 2123.

[0072] Step 10: Fold the front panel 250 90° relative to the front panel 2121 along the second front pressure line 207 so that the front panel 250 is attached to the front panel 2121.

[0073] Finally, the third tongue 260 is folded relative to the front cover plate 250 along the fourth side pressure line 209, so that the third tongue 260 is inserted into the slot 2123f formed by the side plate 2123.

[0074] At this point, the folding process of transforming the packaging structure into a box using 200 folds is complete. It can be seen that the box can be folded from a single sheet of cardboard. The folding process is simple, requiring no additional tools such as glue, saving on material and labor costs, and improving assembly efficiency.

[0075] It is understandable that some of the steps above are not in any particular order. For example, the order of steps one through four can be any, and there is no restriction here.

[0076] Additionally, see Figure 6 and Figure 7 The embodiments of this application also provide a combined packaging structure 10, which includes an outer box 100, a folding packaging structure 200 as described in the above embodiments, a cushioning structure 300, and a corner protection structure 400. The outer box 100 has a hollow inner cavity. When the folding packaging structure 200 is folded... Figure 2 When the packaging box shown is placed inside the outer box 100, the cushioning structure 300 and the corner protector structure 400 can also be placed inside the outer box 100. There are at least two cushioning structures 300, all arranged in pairs. When the packaging box formed by folding the packaging structure 200 is placed inside the outer box 100, the packaging box is held between the two pairs of cushioning structures 300. Each cushioning structure 300 has a hollow cushioning cavity, which protects the product 50 placed inside the packaging box. The corner protector structure 400 also has a hollow cavity, and this cavity includes a corner protector for inserting the end of the packaging box. When the end of the packaging box is inserted into the corner protector cavity, the hollow cavity within the corner protector structure 400 also cushions and protects the end of the packaging box, effectively protecting the packaging box and the product 50 placed inside, preventing the packaging box from being compressed and thus damaging the product 50.

[0077] It is understandable that the number of cushioning structures 300 and corner protectors 400 is unlimited, and their specific number depends on the shape of the packaging box, for example... Figure 7In one embodiment, the packaging box is hexahedral in shape, resulting in four cushioning structures 300. Two cushioning structures 300 are located on the front and rear sides of the packaging box, and the other two are located on the top and bottom sides. Furthermore, there are two corner protectors 400, arranged in pairs with a distance between them. The two ends of the packaging box are inserted into the corner protectors 400, and the distance between the two opposing corner protectors 400 is equal to the length of each cushioning structure 300, ensuring that the four cushioning structures 300 completely cover the portion of the packaging box exposed above the corner protectors. In other embodiments, if the packaging box or product 50 has multiple ends, the number of corner protectors 400 can be determined based on the number of ends of the packaging box or product 50, and there is no particular limitation here.

[0078] It is also understood that the combined packaging structure 10 may only include the outer box 100 and the folding packaging structure 200. The cushioning structure 300 and the corner protection structure 400 can be selected as needed. That is, the combined packaging structure 10 may only include the outer box 100, the folding packaging structure 200 and the cushioning structure 300, or only include the outer box 100, the folding packaging structure 200 and the corner protection structure 400. There is no limitation on this.

[0079] The outer box 100, the cushioning structure 300, and the corner protection structure 400 can be similar to the folding packaging structure 200, each made by folding a piece of cardboard, or they can be made by molding or other processing methods. The specific structure is not limited, and can be referred to the various embodiments of the prior art or improved based on the various embodiments of the prior art. It will not be described in detail here.

[0080] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
