[0002] In the packaging and transportation of products, cushioning and protective packaging plays a crucial role. However, the existing packaging structures for products inside the packaging box still have many shortcomings. For example, they are usually made by splicing multiple cardboard pieces together to form the packaging structure. This structure has poor stability and is difficult to manufacture, resulting in low production efficiency. In addition, the packaging structure usually cannot effectively separate, fix and cushion two or more products. Utility Model Content

[0003] The purpose of this utility model is to provide a packaging structure and packaging box that can improve the fixing and cushioning effect of multiple products.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A packaging structure includes a first packaging section and a second packaging section. Both the first and second packaging sections include: a sleeve box with an opening at one end; a cushioning member disposed inside the sleeve box and on the bottom wall of the sleeve box opposite to the opening; and a barrier member disposed inside the sleeve box and dividing the sleeve box into at least two receiving spaces. The sleeve box, the cushioning member, and the barrier member are all integrally folded from cardboard. One end of the product is received in at least two receiving spaces of the first packaging section, and the other end is received in at least two receiving spaces of the second packaging section.

[0006] As an optional solution to the packaging structure provided by this utility model, the bottom wall of the box is provided with at least two folds. The folds are folded towards the cushioning member and form a placement groove with the cushioning member. The groove opening is opposite to the opening direction and the placement groove is used to accommodate the product accessories.

[0007] As an optional solution to the packaging structure provided by this utility model, the two ends of the cushioning member away from the bottom wall of the box are provided with support seats, and the support seats make the side of the cushioning member facing the bottom wall of the box have a hollow area.

[0008] As an optional solution for the packaging structure provided by this utility model, the buffer is a plate-shaped structure and the support is a hollow paper tube structure.

[0009] As an optional solution to the packaging structure provided by this utility model, the cushioning element and the support base are integrally folded from cardboard.

[0010] As an optional solution to the packaging structure provided by this utility model, the two ends of the barrier are connected to the opposite side walls of the box.

[0011] As an optional solution to the packaging structure provided by this utility model, the barrier has connecting protrusions at both ends, and the opposite side walls of the box have slots for inserting the connecting protrusions.

[0012] As an optional solution to the packaging structure provided by this utility model, at least one side wall of the box is inclined relative to the plane of the cushioning component.

[0013] As an optional solution for the packaging structure provided by this utility model, the cardboard is corrugated paper.

[0014] Secondly, this utility model also provides a packaging box, including a box body and a packaging structure as claimed in any one of the claims, wherein a first packaging part and a second packaging part are placed inside the box body, and the product is disposed between the first packaging part and the second packaging part.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

[0032] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1 to 7 As shown, this utility model provides a packaging structure, including a first packaging section 1 and a second packaging section 2. Both the first packaging section 1 and the second packaging section 2 include: a sleeve box 11, a cushioning member 12, and a barrier member 13. One end of the sleeve box 11 has an opening 111. The cushioning member 12 is disposed inside the sleeve box 11 and on the bottom wall of the sleeve box 11 opposite to the opening 111. The barrier member 13 is disposed inside the sleeve box 11 and divides the sleeve box 11 into at least two accommodating spaces. The sleeve box 11, the cushioning member 12, and the barrier member 13 are all integrally folded from cardboard. One end of the product 10 is accommodated in at least two accommodating spaces of the first packaging section 1, and the other end is accommodated in at least two accommodating spaces of the second packaging section 1.

[0035] It is understood that the packaging structure includes a first packaging section 1 and a second packaging section 2. Furthermore, the first packaging section 1 and the second packaging section 2 have at least partially identical structures, both including a sleeve 11, a cushioning element 12, and a barrier element 13. Each sleeve 11 of the first packaging section 1 and the second packaging section 2 has an opening 111 at one end. Both the first packaging section 1 and the second packaging section 2 also have a cushioning element 12, which passes through the opening 111 and is disposed within the sleeve 11. The cushioning element 12 is located on the bottom wall of the sleeve 11 opposite to the opening 111, allowing the cushioning element 12 to provide cushioning within both the sleeve 11 of the first packaging section 1 and the sleeve 11 of the second packaging section 2. In addition, both the first packaging section 1 and the second packaging section 2 include a barrier 13. The barrier 13 is designed to separate multiple products 10. The barrier 13 is located inside the sleeve 11 and divides the sleeve 11 into at least two receiving spaces, allowing both ends of the product 10 to extend into the respective receiving spaces of the first packaging section 1 and the second packaging section 2. This ensures that one end of the product 10 is received in at least two receiving spaces of the first packaging section 1, and the other end is received in at least two receiving spaces of the second packaging section 2, thus securing both ends of the product 10. Even if the product 10 falls over or is inverted during transportation or handling, the overall stability and cushioning effect of the product 10 can still be guaranteed. Figure 1 For example, both the first packaging section 1 and the second packaging section 2 include a barrier 13. The barrier 13 of the first packaging section 1 can be inserted into the gap at one end of the two products 10, while the barrier 13 of the second packaging section 2 can be inserted into the gap at the other end of the two products 10. This achieves positioning of both ends of the two products 10, allowing a single packaging structure to effectively fix several products 10 while ensuring no interference between adjacent products 10. This effectively prevents damage to multiple products 10 during transportation and handling. For instance, when product 10 is a speaker, which is usually packaged in pairs, the barrier 13 ensures separate positioning of the two speakers. Furthermore, the sleeve 11, buffer 12, and barrier 13 are all integrally folded from cardboard, ensuring the structural stability of the packaging structure while reducing manufacturing difficulty and improving production efficiency.

[0036] It should be noted that since the respective boxes 11 of the first packaging section 1 and the second packaging section 2 are used for packaging both ends of the product 10, the openings 111 of the respective boxes 11 of the first packaging section 1 and the second packaging section 2 should be directly opposite each other. Furthermore, it can be understood that the respective boxes 11 of the first packaging section 1 and the second packaging section 2 in this embodiment are equivalent to the packaging structures at both ends of the product 10, working in conjunction with the cushioning member 12 inside the box 11 for cushioning and with the blocking member 13 inside the box 11 for separation and positioning. It should also be noted that the accommodating space is essentially formed by the cushioning member 12, the blocking member 13, and the side walls of the first packaging section 1 and the second packaging section 2; the accommodating space in the first packaging section 1 will be used as an example for illustration. When the buffer 12 passes through the opening 111 and is disposed within the sleeve 11, positioned on the bottom wall of the sleeve 11 opposite to the opening 111, the bottom wall of the first packaging section 1 is blocked by the buffer 12. Then, this end of the product 10 is actually in contact with the buffer 12. That is, the buffer 12, together with the side wall of the first packaging section 1 and the barrier 13, forms the accommodating space for the product 10. Furthermore, the orientation of the barrier 13 in both the first packaging section 1 and the second packaging section 2 can be adaptively adjusted according to actual usage requirements. Figure 1 For example, this embodiment exemplifies that the barrier 13 of the first packaging part 1 and the second packaging part 2 are arranged facing each other, that is, when the two products 10 have the same shape or the two ends of a single product 10 have the same shape, the barrier 13 of the first packaging part 1 and the second packaging part 2 are arranged facing each other. When the two products 10 have different shapes or the two ends of a single product 10 have different shapes, the barrier 13 of the first packaging part 1 and the second packaging part 2 can be arranged in other ways.

[0037] Furthermore, this embodiment does not provide detailed limitations regarding the integral folding method of the cardboard box 11, buffer 12, and barrier 13, as these are all existing technologies for cardboard folding. Figures 4 to 7 An example of a one-piece folding molding method is given, but other one-piece folding methods are also possible, which will not be elaborated on here.

[0038] It should be noted that the connection between the sleeve 11 and the buffer 12 can be by bonding, plugging, or other methods. For example, when bonding, the buffer 12 is bonded to the bottom wall of the sleeve 11 which is opposite to the opening 111, or the bottom wall of the sleeve 11 and the buffer 12 are of the same shape. In this case, the edge of the buffer 12 will be clamped by the side wall of the sleeve 11, so that the buffer 12 only contacts the bottom wall of the sleeve 11 which is opposite to the opening 111.

[0039] Alternatively, in this embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, the bottom wall of the box 11 is provided with at least two folding portions 112. The folding portions 112 fold towards the buffer member 12 and form a placement groove 113 with the buffer member 12. The groove of the placement groove 113 is opposite to the direction of the opening 111. The placement groove 113 is used to accommodate the accessories of the product 10.

[0040] It is understood that the bottom wall of the box 11 of the first packaging section 1 and the second packaging section 2 is provided with at least two folding parts 112. The folding direction of the folding parts 112 is towards the buffer member 12 inside the box 11. After folding, the folding parts 112 and the side of the buffer member 12 away from the opening 111 together form the placement groove 113, that is, the groove of the placement groove 113 is opposite to the direction of the opening 111. In other words, the external space of the bottom wall of the box 11 of the first packaging section 1 and the second packaging section 2 forms a mounting groove 113 structure. The mounting groove 113 can accommodate the auxiliary parts or other installation components of the product 10. For example, when the product 10 is a speaker, in addition to the speaker body, it also has small parts or installation components such as hanging clips and component replacement parts. In the prior art, the storage of accessories for the product 10 is usually done by setting up a separate accessory storage area, which leads to an increase in the complexity of the packaging structure and production costs, and is also not conducive to the lightweight requirements of the packaging structure. In this embodiment, the setting of the mounting groove 113 can ensure that the aforementioned small parts or installation components such as hanging clips and component replacement parts can be installed therein, thereby ensuring that while reducing the weight of the packaging structure, it can also provide installation space for small parts or installation components such as hanging clips and component replacement parts, further improving the use effect of the installation structure, and thus improving the actual user experience.

[0041] Furthermore, it should be noted that in this embodiment, one of the preferred first packaging section 1 and the second packaging section 2 is provided with the aforementioned folding portion 112 and the placement groove 113, i.e. Figure 1 , Figure 2 , Figure 4 The diagram shows that only the folding part 112 and the placement slot 113 are provided in the first packaging section 1. In this case, the first packaging section 1 is equivalent to packaging the upper half of the product 10, because small parts or installation components such as hanging buckles and replacement parts are usually located at the top of the packaging structure for easy removal and placement by personnel. As for the specific arrangement of the second packaging section 2, it is as follows: Figure 3 , Figure 5 As shown, the second packaging section 2 does not have a folding section 112 or a placement groove 113. This arrangement ensures the ease of manufacturing the second packaging section 2, thereby increasing the manufacturing difficulty of the entire packaging structure.

[0042] However, in other embodiments, both the first packaging section 1 and the second packaging section 2 are provided with the above-mentioned folding portion 112 and the placement groove 113. For example, while the first packaging section 1 is provided with the above-mentioned folding portion 112 and the placement groove 113, the second packaging section 2 is also provided with the above-mentioned folding portion 112 and the placement groove 113. At this time, the second packaging section 2 is equivalent to packaging the lower half of the product 10. Its folding portion 112 is equivalent to being set upward toward the buffer member 12 of the second packaging section 2, and forms the placement groove 113 with the buffer member 12. At this time, the folding portion 112 can provide upward cushioning support for the buffer member 12, further optimizing the cushioning effect of the second packaging section 2 on the lower half of the product 10.

[0043] It should be noted that the specific number of folding parts 112 can be adjusted according to actual usage requirements, and can be as follows: Figure 1 , Figure 2 , Figure 4 The number of folding portions 112 shown is eight, but other numbers are also possible. Regarding the specific formation of the folding portions 112, in this embodiment, a slit is formed on the bottom wall of the sleeve 11, and then the edge of the slit is folded towards the buffer member 12. It can be understood that a slit is formed on the bottom wall surface of the sleeve 11, and the edge of the slit is then folded towards the buffer member 12. This arrangement allows the edge of the slit to act as the sidewall of the mounting groove 113, ensuring simpler and more convenient processing. Furthermore, the form of the slit can be as follows... Figure 2 The folding part 112 shown is formed in such a way that multiple cut edges are bent, which further improves the forming effect of the mounting groove 113 and improves the storage effect of small parts or installation components such as hanging buckles and component replacement parts.

[0044] The specific structure of the buffer 12 is all existing technology. However, as an option, in this embodiment, such as... Figure 1 , Figure 2 and Figure 3 As shown, the buffer 12 has support seats 121 on both ends of the side away from the bottom wall of the sleeve 11. The support seats 121 form a hollow area on the side of the buffer 12 facing the bottom wall of the sleeve 11.

[0045] It is understandable that the side of the cushioning element 12 away from the bottom wall of the box 11 has support seats 121 at both ends of its surface. On this side, the two support seats 121 support the two edges of the cushioning element 12, so that a hollow area is formed in the middle of the cushioning element 12. This arrangement allows the hollow area formed on the side of the cushioning element 12 facing the bottom wall of the box 11 to provide a larger deformation size for the product 10 on the same side. That is, the hollow area can undergo a certain degree of deformation. Therefore, even if the product 10 is bumped during transportation and handling, the hollow area will provide cushioning for the product 10, further ensuring the cushioning effect of the packaging structure. In other words, the setting of the hollow area effectively disperses the external pressure and impact force, thereby ensuring transportation safety. It should also be noted that when the aforementioned folding part 112 and mounting groove 113 are present, the hollow area also provides installation space for the folding part 112 and mounting groove 113. This is because the hollow area exists on the side of the buffer 12 facing the bottom wall of the sleeve 11, and the folding part 112 and mounting groove 113 are also located on this side. This allows the folding part 112 to provide a certain support and buffering effect when the hollow area undergoes buffer deformation.

[0046] Alternatively, in this embodiment, such as Figure 1 , Figure 2 , Figure 3 As shown, the buffer 12 is a plate-shaped structure, and the support 121 is a hollow paper tube structure.

[0047] It is understood that in this embodiment, the buffer 12 is a plate-shaped structure, and support seats 121 are provided at both ends of the plate-shaped buffer 12. The support seats 121 are hollow paper tube structures, which further reduces the structural weight, ensures the lightweight requirements of the packaging structure, and reduces the convenience of personnel handling and transportation.

[0048] Alternatively, in this embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the buffer 12 and the support base 121 are integrally folded from cardboard.

[0049] It is understandable that the cushioning element 12 and the support base 121 are formed by folding the same cardboard as a whole. This not only makes it easy to form the hollow structure of the support base 121, but also reduces the difficulty of manufacturing the cushioning element 12 and the support base 121, further improving the production convenience and efficiency of the packaging structure.

[0050] The barrier 13 is disposed within the housing 11 and divides the housing 11 into at least two receiving spaces. Alternatively, the barrier 13 can be disposed within the housing 11 and connected to the buffer 12. In this embodiment, as... Figure 2, Figure 3 As shown, the two ends of the barrier 13 are connected to the opposite side walls of the sleeve 11.

[0051] It is understandable that the two ends of the barrier 13 are connected to the opposite side walls of the sleeve 11, rather than connecting the barrier 13 to the buffer 12, so that both ends of the barrier 13 are effectively fixed, thereby ensuring the barrier 13's blocking effect on multiple products 10.

[0052] Alternatively, in this embodiment, such as Figure 2 , Figure 3 As shown, the barrier 13 has connecting protrusions 131 at both ends, and the opposite side walls of the sleeve 11 have slots 114 for inserting the connecting protrusions 131.

[0053] It is understood that the barrier 13 is connected to the sleeve 11 through the connecting protrusions 131 at both ends of the barrier 13 and the slots 114 on the opposite side walls of the sleeve 11. This arrangement allows personnel to more easily install and fix the barrier 13 during assembly and production, thereby effectively ensuring the convenience and efficiency of the packaging structure's manufacturing. Of course, in other embodiments, the barrier 13 and the sleeve 11 can also be connected by bonding, integral forming, etc., which are all existing technologies and will not be elaborated on here. It should be noted that the slots 114 are grooves pre-cut in the cardboard, formed after folding.

[0054] Alternatively, in this embodiment, such as Figure 7 As shown, the barrier 13 is integrally folded from cardboard.

[0055] It is understandable that the barrier 13 is integrally folded from cardboard, and the connecting protrusions 131 at both ends are also integrally folded from the cardboard of the barrier 13, which further ensures the structural stability and manufacturing convenience of the barrier 13.

[0056] Alternatively, in this embodiment, such as Figure 3 , Figure 5 As shown, the plane containing at least one side wall of the sleeve 11 is inclined relative to the plane containing the buffer 12.

[0057] Understandably, the plane containing at least one side wall of the sleeve 11 is inclined relative to the plane containing the buffer 12. This allows the side wall of the sleeve 11 to be inclined relative to the buffer 12. Thus, when the entire packaging structure is sealed, this inclined side wall of the sleeve 11 can form a space with the outer packaging structure. This space can store documents such as instruction manuals and product licenses. For example, when the product 10 is a speaker, the speaker's instruction manual can be placed in the aforementioned space, further improving space utilization efficiency and ensuring the effectiveness of the packaging structure and the user experience.

[0058] Alternatively, in this embodiment, such as Figures 1 to 7 As shown, the cardboard is corrugated paper.

[0059] It is understandable that the cardboard material used for components such as the box 11, cushioning element 12, barrier element 13, support base 121, and connecting protrusion 131 is corrugated cardboard. However, existing cushioning and protective packaging technologies still have many shortcomings. For example, they widely use expanded polystyrene (EPS) and expanded polyethylene (EPE) cushioning materials. Although these materials have excellent cushioning and protective properties, their waste is difficult to degrade in the natural environment. Incineration releases harmful gases, which is detrimental to the ecological environment. The use of non-environmentally friendly materials further exacerbates the negative impact on the natural environment. With increasing awareness of environmental protection, there is a growing trend towards green packaging and the application of recyclable materials. Therefore, in this embodiment, the cardboard is corrugated cardboard. Since corrugated cardboard is a recyclable material, it can degrade naturally, be recycled and shredded for papermaking, and has a mature processing technology. Through clever design, a cushioning structure can be created to achieve the protective function of product 10, further ensuring the packaging structure's effectiveness, cost requirements, and environmental benefits.

[0060] As an option, such as Figure 1 , Figure 8 As shown, this embodiment also includes a packaging box, including a box body 100 and a packaging structure, with a first packaging part 1 and a second packaging part 2 placed inside the box body 100, and the product 10 disposed between the first packaging part 1 and the second packaging part 2.

[0061] It is understood that a packaging box includes a box body 100 and a packaging structure, with a first packaging part 1 and a second packaging part 2 placed inside the box body 100, and the product 10 placed between the first packaging part 1 and the second packaging part 2, so that the product 10 is packaged by the first packaging part 1 and the second packaging part 2 and then stored inside the box body 100 of the packaging box.

[0062] Alternatively, the box 100 can be formed by folding cardboard in one piece. This arrangement reduces the difficulty of manufacturing the box 100, thereby improving production efficiency.

[0063] Alternatively, the box 100 may be made of corrugated cardboard. This arrangement ensures that the box 100 is effective in use, meets cost requirements, and is environmentally friendly.

[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
