Abstract
Description
Technical Field
[0001] This application relates to the field of product packaging technology, and in particular to a folding cushioning structure and a combined 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, for some fragile products, a cushioning base made of expanded polystyrene foam or blister packs is usually placed inside the packaging box to cushion the product when it is impacted or dropped, thus protecting it from damage as much as possible. However, expanded polystyrene foam and blister packs can produce harmful substances, and once disposed of, they can cause serious environmental impact. Therefore, how to provide an environmentally friendly, protective, and cost-effective folding cushioning structure for packaging boxes is a research and development topic for the packaging industry. Utility Model Content
[0004] Therefore, it is necessary to address the issues of high manufacturing costs and environmental friendliness of existing cushioning structures used in packaging boxes by providing an easy-to-manufacture and low-cost folding cushioning structure and a combined packaging structure including the folding cushioning structure.
[0005] According to one aspect of this application, a folded buffer structure is provided, comprising:
[0006] substrate;
[0007] A first side plate is integrally connected to one side of the substrate along a first direction, and the first side plate is foldable relative to the substrate.
[0008] The first top plate is integrally connected to the side of the first side plate away from the substrate and can be folded relative to the first side plate;
[0009] After the first side plate and the first top plate are folded in sequence, a buffer space is formed between the first side plate, the first top plate and the substrate.
[0010] The substrate or the first top plate has a first through hole that extends through both sides of its own thickness direction. A bending portion is integrally connected to one edge of the first through hole, and the bending portion can be folded into the buffer space along the edge.
[0011] In one embodiment, the folding buffer structure further includes a second side plate integrally connected to the side of the first top plate away from the first side plate, and the second side plate is foldable relative to the first top plate such that when the first side plate is folded relative to the substrate and the first top plate is folded relative to the first side plate, the side of the second side plate away from the first top plate can be connected to the substrate.
[0012] In one embodiment, the folding buffer structure further includes a second side plate integrally connected to the side of the substrate away from the first side plate along the first direction, and the second side plate is foldable relative to the substrate such that when the first side plate is folded relative to the substrate and the first top plate is folded relative to the first side plate, the side of the second side plate away from the substrate can be connected to the first top plate.
[0013] In one embodiment, the folding buffer structure further includes a second top plate integrally connected to the side of the second side plate away from the substrate, and the second top plate can be folded relative to the second side plate so that when the first side plate, the first top plate, and the substrate form the buffer space, the second top plate can be attached to the first top plate.
[0014] In one embodiment, the first through hole is formed on the first top plate, and the second top plate has a second through hole with the same shape and size as the first through hole; when the second top plate is attached to the first top plate, the second through hole can be aligned with the first through hole.
[0015] In one embodiment, the substrate has a third side plate integrally connected to at least one side along a second direction, and the third side plate is foldable relative to the substrate so that the third side plate can be connected to the first top plate; or, the first top plate has a third side plate integrally connected to at least one side along a second direction, and the third side plate is foldable relative to the first top plate so that the third side plate can be connected to the substrate; wherein, the second direction is perpendicular to the first direction.
[0016] In one embodiment, the folding buffer structure further includes a folding plate. When the third side plate is integrally connected to the substrate, the folding plate is integrally connected to the side of the third side plate away from the substrate. When the third side plate is integrally connected to the first top plate, the folding plate is integrally connected to the side of the third side plate away from the first top plate.
[0017] The folding plate can be folded relative to the third side plate to be inserted into the buffer space when the first top plate and the substrate form the buffer space.
[0018] In one embodiment, the folding plate has a third through hole with the same shape and size as the first through hole. When the folding plate is inserted into the buffer space, the third through hole can be aligned with the first through hole.
[0019] According to another aspect of this application, a combined packaging structure is provided, comprising:
[0020] Outer box;
[0021] As described in any of the above embodiments, the folding buffer structure can be stored in the outer box when folded to form the buffer space, and there are at least two folding buffer structures. All the folding buffer structures are arranged in pairs. When the object to be protected is stored in the outer box, the object to be protected is placed between the two pairs of folding buffer structures.
[0022] In one embodiment, the combined packaging structure further includes an inner box that can be housed in the outer box. The inner box serves as the protected component and is used to house the product. When the folding buffer structure is folded to form the buffer space and housed in the outer box, the inner box is held between a pair of folding buffer structures.
[0023] And / or, the combined packaging structure further includes corner protectors that can be housed in the outer box, wherein when the item to be protected is housed in the outer box, the end of the item to be protected is inserted into the corner protector.
[0024] In one embodiment, the corner protector structure has at least two, all of which are arranged in pairs with a distance between them, and the distance between two oppositely arranged corner protector structures is equal to the dimension of the folded buffer structure along its own length.
[0025] The aforementioned folding cushioning structure and the combined packaging structure including the folding cushioning structure, by dividing a cardboard sheet into a base plate, a first side plate, and a first top plate that are integrally connected in sequence, allows a cushioning space to be formed between the first side plate, the first top plate, and the base plate by folding the first side plate relative to the base plate and the first top plate relative to the first side plate. This cushioning space provides cushioning protection for the components to be protected, resulting in a simple, low-cost, and easy-to-manufacture folding cushioning structure. Furthermore, by providing a first through-hole penetrating both sides of the base plate or the first top plate of the folding cushioning structure, with a bent portion integrally connected to one edge of the first through-hole, the bent portion can provide support between the base plate and the first top plate when folded along the edge into the cushioning space. This ensures that the base plate and the first top plate maintain a consistent distance, preventing the folding cushioning structure from being crushed by external pressure after folding. Simultaneously, users can easily retrieve the folded cushioning structure by inserting their fingers into the first through-hole, making it convenient to remove from the outer box of the combined cushioning structure and thus facilitating user use.

[0036] 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.
[0037] 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.
[0038] 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.
[0039] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0040] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0041] 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.
[0042] One embodiment of this application provides a folding buffer structure, which can be formed by folding a cardboard and is used to place in a packaging box to cushion and protect the item to be protected (such as a fragile product or a packaging box containing such a product) and prevent the item to be protected from being damaged by external impact.
[0043] The structure of the folded buffer 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 can be understood that in other embodiments, the folded buffer structure of this application can be used to buffer and protect any component to be protected, and is not limited here.
[0044] See Figures 1 to 4 , Figure 1 This is a top view of a folding buffer structure 300 according to an embodiment of the present application in its unfolded state. Figure 2This diagram shows an axonometric view of the folded buffer structure 300 after it has been folded and formed according to this embodiment. Figure 3 The top view of the folded buffer structure 300 of this embodiment after folding is shown. Figure 4 It shows Figure 2 An enlarged schematic diagram of region A. An embodiment of this application provides a folding buffer structure 300 that, when unfolded, is approximately cross-shaped; after folding, it forms a hexagonal cube structure, with a hollow buffer space 301 formed inside. Figure 1 and Figure 2 Not shown, see Figure 5 and Figure 6 This allows the buffer space 301 to provide buffer protection for the part to be protected when the folded buffer structure 300 is attached to the outer surface of the part to be protected.
[0045] Specifically, in Figure 1 In one embodiment, the folding buffer structure 300 includes a substrate 310, a first side plate 320, a first top plate 330, a second side plate 340, a second top plate 350, a third side plate 360, and a folding plate 370. The first side plate 320 and the second side plate 340 are integrally connected to opposite sides of the substrate 310 along a first direction (X direction shown in the figure). The first top plate 330 is integrally connected to the side of the first side plate 320 away from the substrate 310. The second top plate 350 is integrally connected to the side of the second side plate 340 away from the substrate 310. There are two third side plates 360 and two folding plates 370. The two third side plates 360 are integrally connected to opposite sides of the substrate 310 along a second direction (Y direction shown in the figure, where the Y direction is perpendicular to the X direction). Each third side plate 360 is integrally connected to a third top plate on the side away from the substrate 310.
[0046] More specifically, the connection line between the first side plate 320 and the substrate 310 is configured as a first front fold line 302, the connection line between the first top plate 330 and the first side plate 320 is configured as a second front fold line 304, the connection line between the second side plate 340 and the substrate 310 is configured as a first rear fold line 303, the connection line between the second top plate 350 and the second side plate 340 is configured as a second rear fold line 305, the connection line between the third side plate 360 and the substrate 310 is configured as a first side fold line 306, and the connection line between the fold plate 370 and the third side plate 360 is configured as a second side fold line 307.
[0047] Thus, as Figure 5As shown, the first side plate 320 can be folded relative to the substrate 310 along the first front fold line 302. After the first side plate 320 is folded, the first top plate 330 can be folded relative to the first side plate 320 along the second front fold line 304 and spaced apart from the substrate 310, so that after the first side plate 320 and the first top plate 330 are folded sequentially, a buffer space 301 is formed between the first side plate 320, the first top plate 330, and the substrate 310; the second side plate 340 can be folded relative to the substrate 310 along the first rear fold line 303, and the second top plate 350 can be folded relative to the second side plate 340 along the second rear fold line 305, so that when the first side plate 320, the first top plate 330, and the substrate 310 form the buffer space 301, they can be attached to the side of the first top plate 330 facing the buffer space 301; at the same time, as Figure 6 As shown, the third side plate 360 can be folded relative to the substrate 310 along the first side fold line 306, and the folding plate 370 can be folded relative to the third side plate 360 along the second side fold line 307. When the first top plate 330 and the substrate 310 form a buffer space 301, the folding plate 370 is inserted into the buffer space 301. When the second top plate 350 is attached to the side of the first top plate 330 facing the buffer space 301, the folding plate 370 is attached to the side of the second top plate 350 facing away from the first top plate 330. This fixes the third side plate 360 and prevents the third side plate 360 from returning to the unfolded state from the folded state relative to the substrate 310.
[0048] Preferably, the second top plate 350 has a dimension in the first direction equal to that of the first top plate 330 in the first direction, so that the second top plate 350 can completely cover the first top plate 330 when it is attached to the first top plate 330.
[0049] With the above structure, the first top plate 330 and the second top plate 350 are stacked to form a two-layer structure, and the folded edge can also be stacked on the first top plate 330 and the second top plate 350, so that after the folded buffer structure 300 is folded and formed, the top part can form a three-layer structure. Moreover, the first side plate 320, the second side plate 340 and the third side plate 360 can be used to support between the substrate 310 and the first top plate 330, thereby reinforcing the folded buffer structure 300 after folding and forming.
[0050] It is understood that the foldable buffer structure 300 provided in this application, after being folded and formed, is not limited to... Figure 5 The structure shown can also be other structures. For example, in the structure of the above embodiment, when the second top plate 350 is folded relative to the second side plate 340, the second top plate 350 can also be attached to the side of the first top plate 330 facing away from the buffer space 301 (i.e., the side of the first top plate 330 facing out of the buffer space 301). At this time, when the folding plate 370 is inserted into the buffer space 301, the folding plate 370 is attached to the first top plate 330.
[0051] It is also understood that the folding buffer structure 300 provided in this application can be other structures when it is in the unfolded state. For example, the second side plate 340 can be integrally connected to the side of the first top plate 330 away from the first side plate 320, and the second side plate 340 can be folded relative to the first top plate 330, so that when the first side plate 320 is folded relative to the substrate 310 and the first top plate 330 is folded relative to the first side plate 320, the side of the second side plate 340 away from the first top plate 330 can be connected to the substrate 310. Furthermore, the third side plate 360 can also be integrally connected to the side of the first top plate 330 along the second direction, so that the third side plate 360 can be folded relative to the first top plate 330 to connect to the substrate 310, or the third side plate 360 can also be integrally connected to the side of the second top plate 350 along the second direction; this is not limited here.
[0052] Of course, in other embodiments, only one third side plate 360 and one folding plate 370 may be provided, or no third side plate 360 and folding plate 370 may be provided. However, it is obvious that by providing two third side plates 360 and two folding plates 370, the folded buffer structure 300 after folding can be better reinforced, which is obviously the best embodiment.
[0053] Additionally, in a preferred embodiment, such as Figure 1 As shown, the first top plate 330 has multiple first through holes 331 penetrating both sides of its thickness direction, and all the first through holes 331 are spaced apart along the second direction; the second top plate 350 has multiple second through holes 351 corresponding one-to-one with the first through holes 331; thus, as shown... Figure 5 As shown, when the first top plate 330 and the second top plate 350 are fitted together, each first through hole 331 can be aligned with a corresponding second through hole 351, thereby enabling the first through hole 331 and the second through hole 351 to communicate with each other. This allows the user to insert their fingers into the first through hole 331 and the second through hole 351, facilitating the removal of the folded buffer structure 300 after folding. Therefore, the folded buffer structure 300 can be easily removed from the packaging box. Alternatively, as... Figure 1 and Figure 6 As shown, a third through hole 371 can also be formed on the folding plate 370. When the folding plate 370 is inserted into the buffer space 301, the third through hole 371 formed on the folding plate 370 can also be aligned with a first through hole 331 and a second through hole 351 that are already aligned with each other. Of course, the first through hole 331 can also be formed on the substrate 310 and penetrate through the opposite sides of the substrate 310 along its own thickness direction. It can be formed as needed and is not limited here.
[0054] Furthermore, based on the above embodiments, such as Figure 3As shown, a bent portion 380 is integrally connected to one edge of the first through hole 331. The bent portion 380 can be folded inward along this edge into the buffer space 301. It can be seen that by providing an integrally connected bent portion 380 on one edge of the first through hole 331, when the bent portion 380 is folded inward into the buffer space 301, the bent portion 380 can play a supporting role between the substrate 310 and the first top plate 330. Therefore, the substrate 310 and the first top plate 330 can always maintain a distance, and the folded buffer structure 300 is prevented from being crushed by external pressure after being folded and formed.
[0055] It is understandable that when the first through hole 331 and the second through hole 351 are aligned with each other, the bent part 380 can also be integrally connected to one edge of the second through hole 351; and when the first through hole 331, the second through hole 351 and the third through hole 371 are all aligned with each other, the bent part 380 can be integrally connected to one edge of any one of the first through hole 331, the second through hole 351 and the third through hole 371.
[0056] The shapes of the first through hole 331, the second through hole 351, and the third through hole 371 are not limited. They can be circular, square, quadrilateral, or any polygon. For example, in the embodiment shown in the figure, the shapes of the first through hole 331, the second through hole 351, and the third through hole 371 are all trapezoidal, and there is no limitation on this.
[0057] The above Figure 1 The illustrated embodiment provides a foldable buffer structure 300, which, when folded, forms... Figure 2 When the folding shape is shown, the folding steps are as follows:
[0058] First, fold the first side plate 320 90° relative to the substrate 310 along the first front pressure line, and then fold the second side plate 340 90° relative to the substrate 310 along the first rear pressure line.
[0059] The second step is to fold the first top plate 330 90° relative to the first side plate 320 along the second front pressure line, and then fold the second top plate 350 90° relative to the second side plate 340 along the second rear pressure line, and align the first through hole 331 of the first top plate 330 and the second through hole 351 of the second top plate 350 with each other.
[0060] The third step is to fold the two third side plates 360 at 90° relative to the substrate 310 along their respective first side pressure lines.
[0061] Fourth step: Fold the two folding plates 370 90° relative to their respective third side plates 360 along their respective second side pressure lines, and insert them into the buffer space 301 to secure the third side plates 360, thereby folding the folded buffer structure 300 into... Figure 2 The forming state in the process.
[0062] See Figure 7 and Figure 8 The embodiments of this application also provide a combined packaging structure 10, which includes an outer box 100, an inner box 200, and a folding cushioning structure 300 as described in the above embodiments. The outer box 100 has a hollow inner cavity, and there are at least two folding cushioning structures 300, all arranged in pairs. When the folding cushioning structures 300 are folded... Figure 2 In the form shown, the folding buffer structure 300 can be stored in the inner cavity of the outer box 100, and the inner box 200 can also be stored in the inner cavity of the outer box 100. At this time, the inner box 200 serves as the part to be protected and is placed between the two pairs of folding buffer structures 300, so that the folding buffer structure 300 can use its internal buffer space 301 to buffer and protect the inner box 200.
[0063] Preferably, the combined packaging structure 10 also includes a corner protection structure 400, which also has a hollow cavity. The corner protection cavity also has a corner protection cavity for inserting the end of the inner box 200. When the end of the inner box 200 is inserted into the corner protection cavity, the hollow cavity in the corner protection structure 400 can also buffer and protect the end of the inner box 200, thereby effectively protecting the inner box 200 and the product 50 placed inside the inner box 200, and preventing the end of the inner box 200 from being compressed and thus damaging the product 50.
[0064] It is understood that the number of folding cushioning structures 300 and corner protection structures 400 is unlimited, and their specific number depends on the shape of the inner box 200, for example... Figure 8 In one embodiment, the inner box 200 is hexahedral in shape, resulting in four folding buffer structures 300. Two folding buffer structures 300 are located on the front and rear sides of the inner box 200, and the other two are located on the top and bottom sides. Additionally, there are two corner protectors 400, arranged in pairs with a gap between them. The two ends of the inner box 200 are inserted into the corner protectors 400, and the distance between the two opposing corner protectors 400 is equal to the length of the buffer structure, ensuring that the four folding buffer structures 300 completely cover the portion of the inner box 200 exposed above the corner protectors 400. In other embodiments, if the inner box 200 or product 50 has multiple ends, the number of corner protectors 400 can be determined based on the number of ends of the inner box 200 or product 50, and there is no particular limitation here.
[0065] It is also understandable that the inner box 200 and the corner protection structure 400 can be selected as needed. That is, the combined packaging structure 10 can also include only the outer box 100 and the folding cushioning structure 300. In this case, the folding cushioning structure 300 directly cushions and protects the product 50, and there is no limitation on this.
[0066] Therefore, the folding buffer structure 300 provided in this application can be folded from just one piece of cardboard. Its structure is simple, low-cost and easy to manufacture. It does not require additional materials or tools, nor does it need to be glued to the inside of the top cover of the outer box 100 or the inner wall of the outer box 100, thus reducing the cost of manual assembly.
[0067] It should be noted that the outer box 100, inner box 200 and corner protection structure 400 can also be similar to the folding cushioning structure 300, each made of a single piece of cardboard folded together, or they can be structures that have already been formed 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.
[0068] 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.
[0069] 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.
