[0049] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0050] Packaging liners, typically used inside product boxes, primarily serve to cushion and protect the packaged product. In current product packaging processes, packaging liners are usually made of materials such as pearl cotton, foam, and cardboard. For example, cushioning protection is provided by adjusting the number of layers and flute shape of the bonded corrugated cardboard. Another example is the use of foam or pearl cotton, which can be customized according to the specific product being packaged, allowing the packaging liner to fit different products, essentially providing cushioning protection by filling the gaps within the packaging box.
[0051] However, the aforementioned packaging liners, in order to ensure that the cushioning strength of the product meets the strength requirements, usually use thicker materials, which results in a large amount of liner material used for packaging each product.
[0052] To address the aforementioned technical issues, a packaging liner is provided. The packaging liner may include a liner body 1, which is formed by folding an integrally molded cardboard. The folded liner body 1 has a groove 101, the wall of which abuts against a product 2 to secure the product 2 within the groove 101. A folded cavity 102 is formed between the outer surface of the folded liner body 1 and the side wall of the groove 101, creating a side buffer space when the liner body 1 contacts the inner side wall of the packaging box 3. A receiving cavity 103 is formed at the bottom of the folded liner body 1, creating a bottom buffer space when the bottom of the liner body 1 contacts the bottom wall of the packaging box 3. The liner body 1, formed by folding the cardboard, can support the structural strength required to hold the product 2, and the folded cavities 102 distributed on the four side walls of the groove 101 and the receiving cavity 103 distributed below the bottom wall of the groove 101 can be obtained through folding. Therefore, after the inner liner body 1 is inserted into the packaging box 3, the folding cavity 102 can provide side cushioning space for the product 2, and the accommodating cavity 103 can provide bottom cushioning space for the product 2. This reduces the amount of material required for each packaging liner while ensuring that the packaging liner meets the cushioning strength required by the product 2.
[0053] Reference Figure 1-5This utility model provides a packaging liner, which includes a liner body 1 formed by folding an integrally molded cardboard. The folded liner body 1 has a groove 101, the wall of which abuts against a product 2 to secure the product 2 within the groove 101. A folding cavity 102 is formed between the outer surface of the folded liner body 1 and the side wall of the groove 101, creating a side buffer space when the liner body 1 contacts the inner side wall of the packaging box 3. A receiving cavity 103 is formed at the bottom of the folded liner body 1, creating a bottom buffer space when the bottom of the liner body 1 contacts the bottom wall of the packaging box 3.
[0054] In this embodiment of the invention, the inner liner body 1 is formed by folding a one-piece molded cardboard. That is, the packaging liner is a one-piece molded structure, requiring only one die-cutting process during its production, which reduces the production steps and costs of the inner liner body 1. In other words, the cardboard is cut using a die to obtain the unfolded inner liner body 1, and then the unfolded inner liner body 1 is folded to obtain the folded inner liner body 1.
[0055] The inner liner body 1 in its folded state is provided with a groove 101, which is used to accommodate the product 2. When the product 2 is embedded in the groove 101, the groove wall of the groove 101 forms pressure contact with the product 2, thereby limiting the position of the product 2 through the groove wall of the groove 101. The groove wall of the groove 101 includes side walls and a bottom wall. The product 2 may include electronic devices such as multimode gateways, and may also include other products 2 that are easily damaged during transportation; however, no further limitations are specified here.
[0056] A folded cavity 102 is formed between the outer surface of the folded inner liner body 1 and the side wall of the groove 101. A receiving cavity 103 is formed at the bottom of the folded inner liner body 1, and the groove 101 and the receiving cavity 103 are separated by the bottom wall of the groove 101. Therefore, when the product 2 is embedded in the packaging liner and then the packaging liner is placed in the packaging box 3, the outer surface of the inner liner body 1 contacts the inner side wall of the packaging box 3. The folded cavities 102 distributed on the four sides of the groove 101 form a side buffer space that provides lateral protection for the product 2. The bottom of the inner liner body 1 contacts the inner bottom wall of the packaging box 3, and the receiving cavity 103 forms a bottom buffer space that provides bottom protection for the product 2. Specifically, when an external impact force is applied to the packaging liner, the deformation of the cardboard in the side buffer space and the bottom buffer space reduces the impact force on the product 2, thereby providing cushioning and protection for the product 2.
[0057] In summary, the packaging liner, while meeting the cushioning strength requirements of product 2, also reduces the amount of material needed for each product 2. For example, it supports the overall structural strength of the packaging liner through a folded structure, significantly reducing the required thickness of the cushioning material. Furthermore, when product 2 has auxiliary product 2 accessories, these accessories can be placed within the accommodating cavity 103, which not only cushions the product 2 but also provides space for the auxiliary product 2 accessories, thereby improving the applicability of the packaging liner. Moreover, compared to the prior art where the liner body 1 needs to be customized according to product 2, this embodiment of the invention reduces mold opening costs and expands the application range of the liner body 1.
[0058] When product 2 is a multimode gateway, the inner liner body 1 can effectively prevent external forces from impacting the multimode gateway during transportation. The groove 101 forms a limit on the multimode gateway, which can prevent protruding parts from being broken by impact and can play an effective buffering role.
[0059] An optional utility model embodiment, referring to... Figure 1 and Figure 3 As shown, the inner lining body 1 may include a bottom surface 11, two first folded portions 12, and two second folded portions 13. The two first folded portions 12 are located on opposite sides of the bottom surface 11. After the end face of the first folded portion 12 away from the bottom surface 11 is folded, it is inserted and fixed to the bottom surface 11. The two second folded portions 13 are located on the other opposite sides of the bottom surface 11. After the end face of the second folded portion 13 away from the bottom surface 11 is folded, it is inserted and fixed to the bottom surface 11. Furthermore, the folded first folded portions 12 and the folded second folded portions 13 are inserted and fixed together. The folded first folded portions 12, the folded second folded portions 13, and the bottom surface 11 together form the groove 101.
[0060] In this embodiment of the invention, the bottom surface 11 serves as the bottom wall of the folded inner lining body 1 and also as the bottom wall of the groove 101. The bottom surface 11 can be rectangular or square, etc. Two first folded portions 12 and two second folded portions 13 are distributed on the four sides of the bottom surface 11, with the two first folded portions 12 and the two second folded portions 13 facing each other. The end face of the first folded portion 12 away from the bottom surface 11 is folded and then faces the bottom surface 11, where it is inserted and fixed. The end face of the second folded portion 13 away from the bottom surface 11 is folded and then faces the bottom surface 11, where it is inserted and fixed. Furthermore, the folded first folded portions 12 and folded second folded portions 13 are fixed by insertion. Thus, without the need for any tools, such as glue or other adhesives, the folding and forming of the inner lining body 1 and the required structural strength can be achieved, improving the folding convenience of the inner lining body 1 and reducing its production cost. The first fold 12 in its folded state and the second fold 13 in their folded state are adjacent to each other and together with the bottom surface 11 form the groove 101. The groove 101 has its opening facing vertically to facilitate the insertion of the product 2.

[0070] An optional utility model embodiment, referring to... Figure 3 and Figure 4 As shown, the first folded surface 121 in the folded state is obtained by folding the first folded surface 121 in the unfolded state along its connection with the bottom surface 11 and downward toward the bottom surface 11. The fifth folded surface 131 in the folded state is obtained by folding the fifth folded surface 131 in the unfolded state along its connection with the bottom surface 11 and downward toward the bottom surface 11. The first folded surface 121, the fifth folded surface 131 in the folded state, and the bottom surface 11 together form the accommodating cavity 103.
[0071] In this embodiment of the present invention, the first folding surface 121 in the unfolded state is folded downwards along the junction of the first folding surface 121 and the bottom surface 11 to obtain the first folding surface 121 in the folded state, wherein the first folding surface 121 in the folded state can be arranged perpendicularly to the bottom surface 11. The fifth folding surface 131 in the unfolded state is folded downwards along the junction of the fifth folding surface 131 and the bottom surface 11 to obtain the fifth folding surface 131 in the folded state, wherein the fifth folding surface 131 in the folded state can be arranged perpendicularly to the bottom surface 11.
[0072] Similarly, the two folded first folding surfaces 121, the two folded fifth folding surfaces 131, and the bottom surface 11 enclose and form the accommodating cavity 103.
