Description

Technical Field

[0001] This utility model belongs to the field of packaging boxes, specifically relating to a split-type cushioning packaging box. Background Technology

[0002] Currently, most packaging boxes on the market adopt an integrated structure design, which has three technical defects: Insufficient pressure resistance: Most packaging relies on a single cushioning layer, which cannot effectively disperse multi-directional impact forces in complex transportation environments. In particular, it lacks reliable support for continuous pressure in the vertical direction (Z-axis), which significantly increases the risk of product deformation under pressure. Lack of directional protection: Traditional honeycomb structures can only provide effective support in a single axis (such as the X or Y axis), and their mechanical performance deteriorates sharply in the direction perpendicular to it, making it difficult to cope with complex stress scenarios such as multi-angle collisions and compression. Poor adaptability and maintainability: The integrated design prevents the packaging box from being flexibly adjusted to the product size, and partial damage requires replacement of the entire box, increasing usage costs. These defects severely limit the packaging's protective effectiveness for delicate products, necessitating a cushioning packaging solution with multi-directional impact resistance, modular adjustability, and easy maintenance.

The outer shell is provided with a mounting groove corresponding to the inner shell. The inner shell is detachably installed in the mounting groove. The inner shell (2) is provided with a placement groove for placing products. The outer shell includes an upper outer plate and a lower outer plate. An outer honeycomb body is provided between the upper outer plate and the lower outer plate. The outer honeycomb body is provided with a plurality of honeycomb-shaped outer support surfaces. Each of the outer support surfaces surrounds and forms the peripheral wall of the mounting groove, so as to horizontally buffer and support the inner shell located in the mounting groove.

[0005] Furthermore, both the outer shell and the inner shell include two first side edges along the Y-axis and two second side edges along the X-axis, and the four outer support surfaces disposed on the side edges together form a quadrilateral periphery of the mounting groove.

[0006] Furthermore, both the outer upper plate and the outer lower plate are provided with a number of outer upper side plates and a number of outer lower side plates extending in all directions.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] like Figure 1-3As shown, this utility model provides a split-type cushioning packaging box, including an outer shell 1 and an inner shell 2. Both the outer shell 1 and the inner shell 2 are paper cuboid structures. The outer shell 1 has a mounting groove 14 in the middle corresponding to the inner shell 2. The inner shell 2 can be detachably installed in the mounting groove 14. The inner shell 2 has five placement slots 24 for placing products in the middle. The outer shell 1 is composed of an upper outer plate 11, a lower outer plate 12, and an outer honeycomb body 13 sandwiched between the two. The outer honeycomb body 13 has several honeycomb-shaped outer support surfaces 15. Each of the outer support surfaces 15 surrounds the peripheral wall of the mounting groove 14 to horizontally cushion and support the inner shell 2 located in the mounting groove 14. The inner shell 2 is composed of an upper inner plate 21, a lower inner plate 22, and a lower inner plate 23. The outer honeycomb 13 and the inner honeycomb 23 sandwiched between the two are combined. The outer honeycomb 13 and the inner honeycomb 23 have supporting and buffering properties, forming the main structure of the outer shell 1 and the inner shell 2. Both the outer honeycomb 13 and the inner honeycomb 23 are provided with honeycomb-shaped through holes 42. The direction of the through holes 42 is the direction in which the honeycomb structure has the strongest support, which is the side end direction of the packaging box. The through holes 42 of the inner honeycomb 23 are only set along a single direction (X-axis or Y-axis). In order to enhance the multi-directional support of the inner shell 2 and its protection to the outside, the through holes 42 of the outer honeycomb 13 are designed to be set along both the Y-axis direction and the X-axis direction, so that the packaging box has the supporting performance of the honeycomb structure in both the Y-axis and X-axis directions. In another embodiment, the outer shell 1 and the inner shell 2 can be of any shape, such as a polygon. At the same time, the number of the outer support surfaces 15 of the polygon can also be multiple, which can achieve the above-mentioned effect.

[0028] In another embodiment, the number and size of the placement slots 24 can be adjusted arbitrarily according to the actual situation, and the above-mentioned effect can be achieved in the same way.

[0029] Most packaging boxes on the market simply wrap the product, which is insufficient to effectively protect against potential risks during transportation. For example, deformation caused by squeezing or puncture by sharp objects may damage the product. To improve the overall structural strength of the packaging box, this application innovatively introduces a honeycomb structure into the main structure of the split-type cushioning packaging box, giving it excellent cushioning (Z-axis) and support (Y-axis and X-axis). To address the issue of the honeycomb structure having only one support direction, this application solves this problem by separating the outer shell 1 and the inner shell 2. The product is placed in the placement slot 24 of the inner shell 2. The outer shell 1 encloses the inner shell 2 to enhance protection. On the other hand, its honeycomb structure (the outer honeycomb body 13) is specially designed to have through holes 42 in both the Y-axis and X-axis directions. This design allows the packaging box to have the support of the honeycomb structure in multiple directions, thereby significantly enhancing the overall structural strength.

[0030] Specifically, such as Figure 4 As shown, in one embodiment of this utility model, the specific structure of the outer honeycomb body 13 and the inner honeycomb body 23 is as follows: multiple support plates 4 are stacked vertically, and the upper and lower ends are fixedly bonded to the outer upper plate 11 and the outer lower plate 12 (or the inner upper plate 21 and the inner lower plate 22) respectively. Adjacent support plates 4 are connected by multiple spaced bonding points 41. On a single support plate 4, the bonding points 41 are arranged horizontally (usually in the Y-axis or X-axis direction) along the plate surface. When bonding, the first bonding point 41 is bonded to the support plate 4 above it, the second horizontal bonding point 41 is bonded to the support plate 4 below it, and so on, thereby forming an array of staggered bonding points. These horizontally adjacent (left and right bonding points 41 on the same support plate) and vertically adjacent (corresponding bonding points 41 on adjacent support plates) bonding points 41 together define and enclose the honeycomb-shaped through holes 42. The honeycomb structure endows the outer honeycomb body 13 and the inner honeycomb body 23 with specific mechanical properties: Z-axis direction (vertical direction): excellent cushioning and compressibility. When the packaging box is subjected to severe impact, the structure can effectively absorb energy and cushion, significantly reducing the impact of external forces on the internal products. X-axis and Y-axis directions (horizontal direction): provide support. It should be noted that the single-direction honeycomb structure has the strongest support only in the axial direction of its through-hole 42 (such as only the X-axis or only the Y-axis), while the support in the direction perpendicular to the axial direction (such as only the Y-axis or only the X-axis) is relatively weak. The key of this application is that by simultaneously setting honeycomb structures (through-holes 42) in both the X-axis and Y-axis directions in the outer honeycomb body 13, the deficiency of insufficient support in the vertical direction of the single-direction honeycomb is perfectly made up for. This design significantly improves the overall structure of the packaging box's impact resistance and deformation resistance in multiple directions.

[0031] Specifically, such as Figure 4-6As shown, in one embodiment of this utility model, both the outer shell 1 and the inner shell 2 include a first side 5 extending along the Y-axis and a second side 6 extending along the X-axis. The honeycomb structure is arranged as follows: Outer shell 1: In the region of its first side 5, the through holes 42 of the outer honeycomb body 13 are axially arranged along the X-axis; In the region of its second side 6, the through holes (42) of the outer honeycomb body 13 are axially arranged along the Y-axis. Inner shell 2: The through holes 42 of its inner honeycomb body 23 are uniformly arranged in a single direction (Y-axis or X-axis). Differences in the manufacturing process: Manufacturing of the inner shell 2: The rectangular upper inner plate 21, the inner honeycomb body 23 with through holes arranged only in a single direction (Y-axis or X-axis), and the rectangular lower inner plate 22 are sequentially stacked and bonded together. The placement groove 2 is made in the middle of the inner shell 2 after bonding and forming. 4. Grooving process: The outer shell 1 is manufactured as follows: The rectangular lower outer plate 12 is kept intact as a base. A rectangular hole corresponding to the shape of the inner shell 2 is machined on the upper outer plate 11 to form a rectangular frame structure. Between the frame strip of this rectangular frame and the lower outer plate 12, two types of outer honeycomb bodies 13 with different honeycomb axes are bonded in sections: In the frame strip area corresponding to the first side 5, the outer honeycomb body 13 with the through hole 42 axially along the X-axis direction is bonded; in the frame strip area corresponding to the second side 6, the outer honeycomb body 13 with the through hole 42 axially along the Y-axis direction is bonded.

[0032] Specifically, such as Figure 7-8 As shown, in one embodiment of this utility model, after assembling the above structure, there is a problem: although the outer honeycomb body 13 and the inner honeycomb body 23 provide good support in the X-axis and Y-axis directions (horizontal direction), the support of the honeycomb structure itself is relatively insufficient in the Z-axis direction (vertical direction). To solve the Z-axis support problem, the following design is adopted: Inner shell 2: The upper inner plate 21 and the lower inner plate 22 are each provided with four inner upper side plates 211 and four inner lower side plates 221 extending in all directions. A bending area is provided at the connection between the side plates and the main plate. By bending, the inner upper side plate 211 and the inner lower side plate 221 are bent and overlapped with each other along the Z-axis direction, together forming the overall outer wall of the inner shell 2. Key feature: The hardness of the inner upper side plate 211 and the inner lower side plate 221 is significantly higher than that of the support plate 4. Support mechanism: These side plates are set along the Z-axis direction, which can provide a certain support force on their own. In addition, their overlapping structure and the fact that all four sides adopt this design work together to significantly enhance the support performance of the inner shell 2 in the Z-axis direction. The same design principle is used on the outer shell 1: The upper outer plate 11 and the lower outer plate 12 are provided with multiple outer upper side plates 111 and outer lower side plates 121 extending in all directions. The outer upper side plates 111 and outer lower side plates 121 are also bent and overlapped with each other along the Z-axis direction to form the overall outer wall of the outer shell 1.

[0033] Specifically, such as Figure 7-8 As shown, in one embodiment of this utility model, the inner edges of the mounting groove 14 and the placement groove 24 are provided with multiple elastic latches extending inward, namely outer latches 141 and inner latches 241. When the product is placed into the placement groove 24, the inner latches 241 bend downward under the force, and the positive pressure generated by its certain rebound force securely latches the product in the groove. When the inner shell 2 is installed into the mounting groove 14, the outer latches 141 also bend downward, so that the inner shell 2 is securely latched in the mounting groove 14. After installation, the bent outer latches 141 are vertically set along the Z-axis. At this time, they not only play a latching role, but also form the inner sidewall of the mounting groove 14, effectively protecting the outer honeycomb body 13 inside from damage.

[0034] Furthermore, a filling block 242 is provided at the bottom of part of the placement groove 24 to accommodate the product size.

[0035] Furthermore, a rigid plate 7 is provided between the inner upper plate 21 and the inner honeycomb body 23. That is, the vertical layers of the inner shell 2 from top to bottom are: the inner upper plate 21, the rigid plate 7, the inner honeycomb body 23, and the inner lower plate 22. The rigid plate 7 has a higher hardness than the inner upper plate 21 and the inner lower plate 22. This sandwich-type rigid plate design effectively improves the overall structural strength and rigidity of the inner shell 2.

[0036] It is worth noting that, such as Figure 7-10 As shown, the packaging box of this application can achieve flat storage, saving storage space. Specifically, the outer shell 1 and the inner shell 2 are separated, and the side panels and latches of the outer upper plate 11, outer lower plate 12, inner upper plate 21 and inner lower plate 22 are flattened and opened to form a horizontal plate. Then, the Z-axis extensibility of the honeycomb structure is used to flatten it as well, so that the outer shell 1 and the inner shell 2 can be flattened and stored. When needed, the side panels and latches are simply stood up along the Z-axis, and the inner shell 2 is placed into the mounting groove 14 of the outer shell 1.

[0037] The working principle of this utility model is explained in detail below: Pre-installation stage: The product is embedded into the placement slot 24 of the inner shell 2, and the inner latch 241 locks the product by bending; the inner shell 2 is inserted into the mounting slot 14 of the outer shell 1 as a whole, and the outer latch 141 is bent and snapped to fix the split structure, while forming a side wall barrier to protect the outer honeycomb body 13; Impact load response stage: Horizontal impact: The through holes 42 in the X / Y axis of the bidirectional honeycomb structure (the outer honeycomb body 13) work together to decompose the impact force to the honeycomb wall surface for dissipation, avoiding stress concentration; Vertical pressure: The bent and overlapping side plates (211 / 221) form a Z-axis reinforced column, which works with the compression energy absorption characteristics of the honeycomb body 23 to resist continuous pressure; Multi-directional composite stress: The hierarchical structure of the outer shell 1 and the inner shell 2 forms a gradient buffer. After the impact energy is initially attenuated by the bidirectional honeycomb structure of the outer shell, the remaining energy is absorbed by the single honeycomb structure of the inner shell; This design achieves a closed-loop protection for all working conditions through three major mechanisms: split collaboration, multi-level energy dissipation, and dynamic adaptation.

[0038] The innovation of this utility model lies in: Firstly, it significantly enhances multi-directional impact resistance: through an innovative split-type honeycomb structure design, a two-way mechanical support network is formed in the horizontal plane (X / Y axis), while a reinforced compression resistance mechanism is integrated in the vertical direction (Z axis), significantly improving the packaging box's ability to disperse impact forces in multiple directions and reducing product damage rates. Secondly, it offers dynamic stress self-adaptation: the split modular architecture allows the packaging box to quickly adjust the layout of buffer units according to product size. Combined with the compressibility of the honeycomb structure, it achieves directional absorption and dissipation of impact energy, effectively mitigating the risk of random collisions during transportation. Thirdly, it optimizes the entire life cycle cost: the independent detachable design of the inner and outer shells allows for partial replacement of damaged modules, reducing maintenance costs; the lightweight paper structure balances environmental protection requirements with logistics efficiency, resulting in a decrease in overall usage costs. This design fundamentally solves the core pain points of traditional packaging, such as insufficient multi-directional protection and poor adaptability.
