Description

Technical Field

[0001] This application relates to the field of packaging product technology, and in particular to a multi-layer nested packaging structure. Background Technology

[0002] Packaging boxes are a type of packaged product. They are containers used to hold, protect, and display goods. They can not only effectively prevent goods from being damaged by collisions or squeezing during transportation and storage, but also attract consumers' attention and increase the added value of goods through their exquisite appearance design.

[0003] However, traditional packaging boxes are mostly single-layer structures with simple box shapes and poor cushioning performance. During transportation and handling, they are prone to damage to the contents due to collisions and squeezing, and cannot effectively protect the items. Utility Model Content

[0004] The purpose of this application is to provide a multi-layer nested packaging structure with multiple layers of cushioning protection, which effectively absorbs external impact forces, significantly reduces the risk of damage to internal items due to collision and compression, improves the safety of items during transportation and storage, and solves the problems mentioned in the background art.

[0005] The multi-layer nested packaging structure provided in this application adopts the following technical solution: A multi-layer nested packaging structure includes an outer main box body, a middle nested buffer layer, and an inner partition bearing component. The outer main box body is connected by an integrated folding connection. The outer main box body includes a box bottom. The front end of the box bottom is integrally formed with a front folding part, the rear end of the box bottom is integrally formed with a rear folding part, the top of the rear folding part is integrally formed with a box lid, the top of the box lid is integrally formed with a box lid folding part, the top of the box lid folding part is integrally formed with an insertion part, and both sides of the box bottom are provided with side folding parts. The middle nested buffer layer is adapted to and nested inside the outer main box. The middle nested buffer layer is folded in one piece to form a box structure. The middle nested buffer layer includes a bottom plate and an inwardly folded side wall integrally formed with the edge of the bottom plate. A buffer gap is left inside the inwardly folded side wall. An arc-shaped support plate is placed inside the middle nested buffer layer. The inner layer separating and supporting component is placed inside the middle nested buffer layer. The inner layer separating and supporting component includes multiple foldable inner trays with receiving slots. Foldable connecting pieces are fixedly connected between the inner trays laterally. Foldable buffer pieces are integrally formed on the outer side of the inner trays.

[0006] By adopting the above technical solution, by leaving buffer gaps inside the four inward-folding side walls, setting arc-shaped support plates inside the middle nested buffer layer, and nesting the middle nested buffer layer inside the outer main box, setting folding connecting pieces between the inner trays, and setting folding buffer pieces on both sides of the inner trays, a multi-layer buffer protection is formed, which effectively absorbs external impact forces, greatly reduces the risk of internal items being damaged by collisions and squeezing, and improves the safety of items during transportation and storage.

[0007] Preferably, the bottom of the front folding portion has a socket corresponding to the insertion portion.

[0008] By adopting the above technical solution, during the assembly of the packaging structure, the plug-in part can be inserted into the plug hole to close the outer main box, making the connection of each part of the outer main box more stable. This effectively prevents the outer main box from being accidentally opened due to external forces during transportation or handling, thereby better protecting the internal items and improving the overall stability and reliability of the packaging structure.

[0009] Preferably, the outer main box is made of rigid color-printed cardboard, the middle nested buffer layer is made of gold-colored buffer cardboard, and the arc-shaped support plate has certain resilience.

[0010] By adopting the above technical solution, the outer main box is made of rigid color-printed cardboard. The rigid cardboard gives the outer main box good resistance to pressure and deformation, providing basic protection for the contents. The color printing enhances the aesthetics of the packaging and meets the display needs of different packaging themes. The middle nested buffer layer is made of gold-colored buffer cardboard. Gold not only increases the visual appeal of the packaging, but the buffer cardboard can also effectively absorb and disperse external impact. The curved support plate has a certain degree of resilience and can undergo elastic deformation when squeezed, further buffering external forces and further reducing the risk of damage to the contents due to collision and squeezing.

[0011] Preferably, the inner support plate is hollow inside and has a certain elastic rebound characteristic, and both the folding connecting piece and the folding buffer piece are wavy folding structures.

[0012] By adopting the above technical solutions, the hollow structure and elastic rebound characteristics enable the inner tray to have a certain buffering rebound, which buffers the products in the accommodating slot when impacted, optimizing the buffering effect of the packaging structure. Both the folding connecting piece and the folding buffer piece are wavy folding structures. The wavy structure has good elasticity and buffering performance. When subjected to external impact, it can absorb and disperse energy through its own deformation, further enhancing the buffering protection of the internal products and effectively reducing the probability of damage to the items.

[0013] Preferably, the bottom of the box and the side folding part are integrally formed by folding, and the two sides of the front folding part and the rear folding part are integrally formed by folding, and the two sides of the box lid and the box lid folding part are flush with the bottom extension and the side extension.

[0014] By adopting the above technical solution, the bottom extension and side extension are set, and the two sides of the box cover and the box cover folding part are flush with the extension, so that the two sides of the packaging structure can extend outward and protrude, thereby making the two sides of the overall packaging structure concave. This not only increases the three-dimensional aesthetics of the overall packaging structure, but also makes it easier to pick up and put down.

[0015] Preferably, a folding connection is integrally formed between the side folding portion and the side extension portion.

[0016] By adopting the above technical solution, the folding connector can connect the side fold and the side extension, preventing the side fold and the side extension from being easily opened after packaging.

[0017] Preferably, the lid has a first inward folding portion integrally formed on both sides, a second inward folding portion integrally formed at the top of the front folding portion, and a third inward folding portion integrally formed at the top of the side folding portion.

[0018] By adopting the above technical solution, the inner folding parts can cooperate and squeeze each other after the packaging structure is assembled, forming a certain limiting effect, which further enhances the tightness of the connection between the various parts after the outer main box is assembled and improves the stability of the packaging structure.

[0019] Preferably, the outer surface of the outer main box is printed with a decorative pattern that matches the packaging theme.

[0020] By adopting the above technical solutions, decorative patterns can be customized according to different product types, brand characteristics, or usage scenarios, making the packaging more personalized and attractive, meeting the market's demand for diversified product packaging, and enhancing the overall image and brand value of the product.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This multi-layered nested packaging structure features buffer gaps inside the four inward-folding side walls, an arc-shaped support plate inside the middle nested buffer layer, and the middle nested buffer layer nested within a rigid outer main box. The inner trays are hollow, with folding connecting pieces between them and folding buffer pieces on both sides. This multi-layered buffer protection effectively absorbs external impacts, significantly reducing the risk of damage to internal items due to collisions and compression, and improving the safety of items during transportation and storage. The modular design of each layer, using folding and nesting, facilitates industrial production. The overall structure makes assembly, opening, and storage operations simple, enhancing the user experience. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0025] Example 1: A multi-layer nested packaging structure, referring to... Figure 1 and Figure 2It includes an outer main box 1, a middle nested buffer layer 2, and an inner partition and support component 3. The outer main box 1 is connected by an integrated folding mechanism. The outer main box 1 includes a box bottom 101. The front end of the box bottom 101 is integrally formed with a front folding part 102. The rear end of the box bottom 101 is integrally formed with a rear folding part 103. The top of the rear folding part 103 is integrally formed with a box lid 104. The top of the box lid 104 is integrally formed with a box lid folding part 105. The top of the box lid folding part 105 is integrally formed with an insertion part 106. The two sides of the box bottom 101 are provided with side folding parts 107.

[0026] Reference Figure 1 and Figure 2 The bottom of the front folding part 102 is provided with an insertion hole 109 corresponding to the insertion part 106. When the packaging structure is assembled, the insertion part 106 can be inserted into the insertion hole 109 to close the outer main box 1, making the connection of each part of the outer main box 1 more stable. This effectively prevents the outer main box 1 from being accidentally opened due to external force during transportation or handling, thereby better protecting the internal items and improving the overall stability and reliability of the packaging structure.

[0027] Reference Figure 1 , Figure 3 and Figure 4 The middle nested buffer layer 2 is adapted to the internal space of the outer main box 1 and nested inside the outer main box 1. The middle nested buffer layer 2 is folded in one piece to form a box structure. The middle nested buffer layer 2 includes a base plate 201 and an inwardly folded side wall 202 integrally formed with the edge of the base plate 201. A buffer gap 203 is left inside the inwardly folded side wall 202. An arc-shaped support plate 204 is placed inside the middle nested buffer layer 2.

[0028] Reference Figure 2 , Figure 3 and Figure 4 The outer main box 1 is made of rigid color-printed cardboard, the middle nested buffer layer 2 is made of gold-colored buffer cardboard, and the curved support plate 204 has certain resilience. The rigid cardboard of the outer main box 1 gives it good resistance to pressure and deformation, providing basic protection for the contents. The color printing enhances the aesthetics of the packaging and meets the display needs of different packaging themes. The gold-colored buffer layer 2 not only increases the visual appeal of the packaging, but also effectively absorbs and disperses external impact. The curved support plate 204 has certain resilience and can undergo elastic deformation when squeezed, further buffering external forces and reducing the risk of damage to the contents due to collision and squeezing.

[0029] Reference Figure 1 and Figure 5The inner layer partition bearing component 3 is placed inside the middle nested buffer layer 2. The inner layer partition bearing component 3 includes multiple foldable inner trays 301 with receiving slots. Foldable connecting pieces 302 are fixedly connected between the transverse inner trays 301. Foldable buffer pieces 303 are integrally formed on the outer side of the inner trays 301.

[0030] Reference Figure 5 The inner tray 301 is hollow and has a certain elastic rebound characteristic. The folding connecting piece 302 and the folding buffer piece 303 are both wavy folding structures. The hollow structure and elastic rebound characteristic enable the inner tray 301 to perform a certain buffer rebound, which buffers the product in the accommodating slot when it is impacted, thus optimizing the buffering effect of the packaging structure. The folding connecting piece 302 and the folding buffer piece 303 are both wavy folding structures. The wavy structure has good elasticity and buffering performance. When it is impacted by external force, it can absorb and disperse energy through its own deformation, further enhancing the buffering protection of the internal product and effectively reducing the probability of damage to the item.

[0031] Reference Figure 1 and Figure 2 The outer surface of the outer main box 1 is printed with decorative patterns that match the packaging theme. The decorative patterns can be customized according to different product types, brand characteristics or usage scenarios, making the packaging more personalized and attractive, meeting the market's demand for diversified product packaging, and enhancing the overall image and brand value of the product.

[0032] The integrated folding structure and decorative pattern design of the outer main box 1 ensure structural strength while providing a good visual display effect. When opened, the internal layers can be seen directly, enhancing the product's aesthetics and sense of quality. The structural design of the middle gold buffer layer and the inner folding tray not only strengthens the cushioning protection but also enhances the visual sense of layering through the layered structure.

[0033] Example 2: A multi-layer nested packaging structure, referring to... Figure 1 and Figure 2 The bottom 101 and the side folding part 107 are integrally formed by folding to form a bottom extension 110. The front folding part 102 and the rear folding part 103 are integrally formed with side extensions 111 on both sides by folding. The sides of the lid 104 and the lid folding part 105 are flush with the bottom extension 110 and the side extensions 111. The setting of the bottom extension 110 and the side extensions 111, as well as the sides of the lid 104 and the lid folding part 105 being flush with the extensions, enable the two sides of the packaging structure to extend outward and protrude, thereby making the two sides of the overall packaging structure concave. This not only increases the three-dimensional aesthetics of the overall packaging structure, but also makes it easier to pick up and put down.

[0034] Reference Figure 1 and Figure 2A folding connector 108 is integrally formed between the side folding part 107 and the side extension part 111. The folding connector 108 can connect the side folding part 107 and the side extension part 111, preventing the side folding part 107 and the side extension part 111 from being easily opened after packaging.

[0035] Reference Figure 1 and Figure 2 The lid 104 has a first inward folding part 112 integrally formed on both sides, a second inward folding part 113 integrally formed at the top of the front folding part 102, and a third inward folding part 114 integrally formed at the top of the side folding part 107. The inward folding parts can cooperate and squeeze each other after the packaging structure is assembled, forming a certain limiting effect, further enhancing the tightness of the connection between the various parts after the outer main box 1 is assembled, and improving the stability of the packaging structure.

[0036] It should be noted that the size of the inner tray 301 and the accommodating slot can be adjusted and assembled according to the quantity and size of the products, and the internal structure can be flexibly adjusted so that the inner tray 301 can be adapted to various products for packaging. The inner tray 301 can be connected by the folding connecting piece 302 and the folding buffer piece 303 can be used to cushion and protect the two sides of the inner tray 301. This adapts to the packaging needs of different types of consumer goods and improves the versatility of the structure.

[0037] The implementation principle of this application embodiment is as follows: The outer main box 1 of rigid color-printed cardboard is folded in an integrated manner to form a stable structure. The middle nested buffer layer 2 can be nested inside the folded and assembled outer main box 1. After the lid 104 of the outer main box 1 is closed, the insertion part 106 is inserted into the insertion hole 109 to achieve a stable connection when the packaging structure is closed. The gold buffer cardboard material has both visual appeal and buffering performance. The buffer gap 203 and the arc-shaped support plate 204 inside the inner folding side wall 202 absorb the impact force through elastic deformation. When external force is applied, the buffer gap 203 provides deformation space, and the arc-shaped support plate 204... The rebound properties disperse energy, reducing the risk of damage to internal items. Products can be placed in the receiving slot of the inner tray 301. The hollow design and elastic rebound properties of the inner tray 301, together with the wavy folding connecting piece 302 and the folding buffer piece 303, form a buffer. When impacted, the inner tray 301 compresses and rebounds through the hollow structure, and the folding connecting piece 302 and the folding buffer piece 303 absorb energy through deformation, protecting the products in the receiving slot. Each level adopts a folding and nesting modular design, which is convenient for industrial production. The overall structure makes assembly, opening and storage operations simple, improving the user experience.
