Description

Technical Field

[0001] This utility model relates to the field of corrugated packaging technology, specifically to a full-paper elastic cushioning liner. Background Technology

[0002] Currently, corrugated cardboard has become the mainstream cushioning material to replace foam plastics due to its readily available raw materials, mature processing technology, low cost, and recyclability and biodegradability. It is widely used in the lining, corner protectors, and edge protectors of packaging for electronic products, cosmetics, wine, and other products. The corrugated cardboard cushioning linings for fragile electronic devices such as computers and monitors are developing towards multi-layer composites, digital simulation, and modular "one-piece molding," providing basic shockproof protection while meeting green and environmental protection requirements.

[0003] Corrugated cardboard cushioning linings utilize multiple mechanisms, including the corrugated elasticity of the corrugated structure, the air cushioning cavity in the structural design, positioning buckles, and multi-layer composites, to absorb impacts, reduce vibrations, and limit displacement during the transportation and handling of fragile electronic devices such as computers and monitors. This provides reliable cushioning protection in common risk scenarios such as logistics handling, stacking, and drops.

[0004] However, due to the high rigidity of corrugated cardboard, the corrugated structure and cushioning cavity structure have limited recovery ability after impact. At the same time, because the elasticity of the cushioning cavity structure is very limited, the cardboard first compresses or even destroys these structural cavities during impact to absorb most of the impact energy, resulting in a significant decrease in the protective effect after multiple drops. In addition, the thicker or multi-layered padding leads to a larger packaging volume and difficulty in adapting to complex shapes. These are still key bottlenecks that restrict the full replacement of traditional foam materials by corrugated cardboard cushioning liners in the packaging of high-value electronic products.

[0005] Therefore, there is an urgent need to develop an innovative cushioning liner that combines the cushioning cavity structure of traditional cushioning liners with the elastic energy absorption and rebound of a paper spring structure, thus solving the aforementioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide an all-paper elastic cushioning liner that combines a cushioning cavity structure and an elastic paper spring structure through structural design, thereby solving the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: A paper-based elastic cushioning liner is formed by die-cutting and creasing corrugated cardboard and then folding it into a single sheet. It includes a triangular cushioning cavity and an elastic cushioning assembly. The triangular cushioning cavity includes a base plate and two support plates. One side of each support plate is connected to opposite sides of the base plate via creasing lines. The other side of each support plate is movably fastened together by the elastic cushioning assembly. The elastic cushioning assembly includes a connecting plate, a cushioning plate, and a latch. The connecting plate extends outward from the support plates and is directly connected to the cushioning plate, and creasing lines are provided on the connecting plate.

[0008] Furthermore, the connecting plate and the bayonet of the elastic buffer assembly are arranged in pairs and are equally spaced and cross-arranged in multiple pairs.

[0009] Furthermore, the width of the buffer plate is greater than the width of the connecting plate and the bayonet, and the width of the bayonet is greater than the width of the connecting plate.

[0010] Furthermore, the all-paper elastic cushioning liner is used in pairs.

[0011] The beneficial effects of this utility model are: This invention combines a triangular buffer cavity and an elastic buffer assembly. The connecting plate of the elastic buffer assembly and the buffer plate form an elastic structure under the action of the indentation line, ultimately forming a paper spring that combines the energy-absorbing structure of the buffer cavity and the elastic buffer structure. This gives it the dual advantages of being lightweight and high-strength, ensuring that electronic products such as computers and monitors, as well as other fragile items, can easily cope with various harsh environments during daily storage, handling, and logistics transportation, providing excellent cushioning protection. Moreover, the structure is simple, assembly is quick, and it is suitable for mass industrial production. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1-6 As shown, this embodiment discloses a paper-based elastic cushioning liner 100, which is formed by die-cutting and creasing corrugated cardboard and then folding it into shape. It includes a triangular cushioning cavity 1 and an elastic cushioning assembly 2. The triangular cushioning cavity 1 includes a base plate 11 and two support plates 12. One side of the two support plates 12 is connected to the opposite sides of the base plate 11 through creasing lines 3, and the other side of the two support plates 12 is movably fastened together through the elastic cushioning assembly 2. The elastic cushioning assembly 2 includes a connecting plate 21, a cushioning plate 22 and a latch 23. The connecting plate 21 extends outward from the support plate 12 and is directly connected to the cushioning plate 22. The connecting plate 21 is provided with creasing lines 3.

[0020] The connecting plate 21 and the bayonet 23 of the elastic buffer assembly 2 are arranged in pairs and are equally spaced and cross-arranged in multiple pairs. For example... Figure 2As shown, the first connecting plate 211 extending outward from the second support plate 122 is paired with the first latch 231 on the first support plate 121, and the second connecting plate 212 extending outward from the first support plate 121 is paired with the second latch 232 on the second support plate 122. In this embodiment, a total of 6 pairs of connecting plates 21 and latches 23 are provided. Only two pairs are marked in the figure for illustration. The other four pairs are not marked, but they are essentially the same as the marked first support plate 121, second support plate 122, etc., so they will not be described in detail. Since the other side of the two support plates 12 are movably fastened together by the elastic buffer assembly 2, that is, the connecting plate 21, buffer plate 22 and latch 23 interlock to form a movable latch, so that the triangular buffer cavity 1 and the elastic buffer assembly 2 can jointly form the effect of a paper spring, multiple pairs of connecting plates 21 and latches 23 need to be equally spaced and cross-set. Equal spacing means that the first connecting plate 211, the second connecting plate 212, etc., are 6 pairs of connecting plates 211 and 212. The width of the connecting plate 21 is consistent. Similarly, the width of the six latches 23, including the first latch 231 and the second latch 232, is consistent. Their cross arrangement is to ensure that the first support plate 121 and the second support plate 122 lock together. The six connecting plates 21, including the first connecting plate 211 and the second connecting plate 212, must appear crosswise on the sides of the second support plate 122 and the first support plate 121. Likewise, the six latches 23 must also be arranged so that when the first support plate 121 and the second support plate 122 are locked together… The first buffer plate 221, which is directly connected to the first connecting plate 211, is locked in the first latch 231. The second buffer plate 222, which is directly connected to the second connecting plate 212, is locked in the second latch 232, and so on, to complete all the locking. In order to facilitate locking, the width of the latch 23 must be greater than the width of the connecting plate 21 so that the connecting plate 21 can be locked in the latch 23. The width of the buffer plate 22 must be greater than the width of the latch 23 to ensure that the buffer plate 22 is locked in the latch 23.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, after the paper elastic buffer liner 100 is locked, since it is not subjected to pressure, its second support plate 122, first connecting plate 211 and first buffer plate 221 are in a straight line, the first support plate 121, second connecting plate 212 and second buffer plate 222 are in a straight line, and so on.

[0022] like Figure 2 , Figure 4 and Figure 5As shown, when the all-paper elastic cushioning liner 100 is installed in the packaging box as a cushioning pad after locking, the first connecting plate 211 bends along the crease line 3 provided thereon due to the pressure, so that an angle is formed between the second support plate 122 and the first cushioning plate 221; similarly, the second connecting plate 212 bends along the crease line 3 provided thereon, so that an angle is formed between the first support plate 121 and the second cushioning plate 222, and so on.

[0023] After the connecting plate 21 is bent, the entire elastic cushioning assembly 2 makes elastic line contact between the cushioning plate 22 and the fragile item when it comes into contact with the packaged item. Meanwhile, the bottom plate 11 of the triangular cushioning cavity 1 contacts the inner wall of the outer packaging box. The triangular cushioning cavity 1 and the elastic cushioning assembly 2 together form a paper spring structure. When the item is dropped during handling or transportation, the all-paper elastic cushioning liner 100 is subjected to the impact force of the fragile item inside the packaging. This causes the cushioning plate 22 to be elastically compressed under the action of the indentation line 3 on the connecting plate 21, thus forming a spring. Figure 6 The elastic line contact shown is transformed into an elastic surface contact.

[0024] To ensure the desired cushioning effect, the all-paper elastic cushioning liner 100 is used in pairs inside the packaging box. Depending on different cushioning needs, more than one pair of all-paper elastic cushioning liners 100 can be used.

[0025] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
