Figure 7 The diagram schematically illustrates the forming process of stretch paper 50. To better understand this application, the following is combined with... Figures 1 to 7 Describe it.

[0045] See Figures 1 to 5 As shown, this application embodiment provides a packaging box 10, which includes a paper outer box 20 and an article support component 30.

[0046] The paper outer box 20 includes a receiving portion 201. An article support assembly 30 is disposed within the receiving portion 201. The article support assembly 30 includes a paper liner 40. The paper liner 40 is detachably connected to a stretch paper 50 to form a storage portion for placing an article 100 to be packaged. The storage portion can securely and detach the article 100 to be packaged. The paper liner 40 includes a first support portion 41 and a first hook portion 42. The first hook portion 42 is used to connect to the stretch paper 50. The first support portion 41 forms the storage portion between itself and the stretch paper 50. When the article 100 to be packaged is placed in the storage portion, the stretch paper 50 applies pressure to the article 100 to secure it.

[0047] The packaging box 10 of this application embodiment includes an article support assembly 30 for fixing the position of the article 100. The article support assembly 30 includes a paper liner 40. The paper liner 40 is detachably connected to the stretch paper 50 to form a storage section for placing the article 100 to be packaged. The first hook portion 42 of the paper liner 40 is used to achieve a detachable connection with the stretch paper 50 by hooking them together, thereby facilitating the assembly or separation of the paper liner 40 and the stretch paper 50 and improving the efficiency of assembly or separation. The paper liner 40 is made of paper material. When the paper liner 40 and the stretch paper 50 are connected, no adhesive is required, so the packaging box 10 itself has good environmental friendliness and helps to reduce the possibility of environmental pollution. The paper outer box 20 can protect the article support assembly 30 and the article 100, facilitate the transfer and circulation of the article 100, and reduce the possibility of damage to the article 100. The paper outer box 20 is made of paper, so the paper outer box 20 itself is environmentally friendly and helps to reduce the possibility of environmental pollution.

[0048] In some possible implementations, the stretch paper 50 includes a second support portion 51 and a second hook portion 52. The second hook portion 52 is detachably connected to the first hook portion 42 in a hook-and-hook manner. A first support portion 41 is provided corresponding to the second support portion 51. A storage portion is formed between the first support portion 41 and the second support portion 51. When the item 100 to be packaged is placed in the storage portion, the second support portion 51 of the stretch paper 50 applies pressure to the item 100.

[0049] The paper backing board 40 and the stretch paper 50 can be detachably connected by hooking together the first hook part 42 and the second hook part 52, which facilitates the assembly or separation of the paper backing board 40 and the stretch paper 50 and improves the efficiency of assembly or separation. The stretch paper 50 is made of paper, which helps reduce the possibility of environmental pollution. The stretchability of the stretch paper 50 can be adaptively adjusted according to the size and shape of the item 100 to effectively fix items 100 of different sizes and shapes, thus improving the versatility of the packaging box 10.

[0050] In the embodiments of this application, see Figure 4 and Figure 5As shown, the item support component 30 is used to support and secure the item 100 to be packaged. The item support component 30, with the item 100 secured, can be placed inside the receiving portion 201 of the paper outer box 20. The paper outer box 20 provides protection for both the item support component 30 and the item 100. The item support component 30 can fix the position of the item 100, reducing the possibility of the item 100 moving freely within the paper outer box 20. Stretch paper 50 refers to a paper product whose dimensions can increase when subjected to tensile force and shrink back to its initial state when the tensile force is removed. Stretch paper 50 can cover the item 100 to limit and protect it.

[0051] In this embodiment, the packaging process of article 100 may involve providing a paper backing board 40 and stretch paper 50. The second hook portion 52 of the stretch paper 50 is hooked onto the first hook portion 42 of the paper backing board 40 to complete the assembly between the paper backing board 40 and the stretch paper 50. No adhesive is required during the assembly of the paper backing board 40 and the stretch paper 50. After the paper backing board 40 and the stretch paper 50 are assembled, the stretch paper 50 can be in a stretched state, and a storage portion is formed between the first support portion 41 and the second support portion 51. Article 100 to be packaged is provided, and the stretch paper 50 is pulled in a direction away from the paper backing board 40, placing the article 100 into the storage portion formed between the first support portion 41 and the second support portion 51. The stretch paper 50 is released, and under the pressure of the article 100, the stretch paper 50 is further stretched, allowing the second support portion 51 to apply pressure to the article 100 to fix its position. Then, the item support component 30, which secures the item 100, is placed inside the receiving portion 201 of the paper outer box 20. The paper outer box 20 covers the item support component 30 and the item 100.

[0052] The removal of item 100 can be performed by detaching the second hook portion 52 of the stretch paper 50 from the first hook portion 42 of the paper backing 40 to separate the stretch paper 50 and the paper backing 40. The stretch paper 50 is then removed, making the item 100 fully visible, and then the item 100 is removed. Alternatively, the removal of item 100 can be performed by pulling the stretch paper 50 away from the paper backing 40, pushing or pulling the item 100 between the first support portion 41 and the second support portion 51 to remove the item 100 from between the first support portion 41 and the second support portion 51, and then releasing the stretch paper 50.

[0053] See also some of the possible implementation methods. Figure 2 and Figure 3 As shown, along the first direction X, a first hook-up portion 42 is provided on each of the opposite sides of the first support portion 41, and a second hook-up portion 52 is provided on each of the opposite sides of the second support portion 51.

[0054] After the item 100 to be packaged is placed between the first support part 41 and the second support part 51, the first hook part 42 and the second hook part 52 provided on both sides can help ensure that the second support part 51 applies a more balanced pressure to the item 100, so that the item 100 has good positional stability and is not easy to shake relative to the item support component 30.

[0055] After the first hook-up part 42 and the second hook-up part 52 are hooked together, it is convenient to place the item 100 between the stretch paper 50 and the paper backing board 40 in areas where the second hook-up part 52 has not been installed, thus reducing the difficulty of placing the item 100.

[0056] When assembling the stretched paper 50 and the paper backing board 40, one method is to first stretch the stretched paper 50, and then simultaneously hook the second hooking parts 52 on both sides of the second support part 51 to the corresponding first hooking parts 42. Another method is to first hook the second hooking part 52 on one side of the stretched paper 50 to the corresponding first hooking part 42, then stretch the stretched paper 50, and then hook the second hooking part 52 on the other side of the stretched paper 50 to the corresponding first hooking part 42. The stretched paper 50 and the paper backing board 40 can be assembled in various ways, allowing for flexible selection of the assembly method. This also helps to reduce the difficulty of assembling the stretched paper 50 and the paper backing board 40 and improve assembly efficiency.

[0057] See in some examples Figure 2 and Figure 3 As shown, along the first direction X, a first hook part 42 is provided at two opposite edges of the paper backing board 40, and a second hook part 52 is provided at two opposite edges of the stretched paper 50, so that the support area of ​​the first support part 41 and the second support part 51 is larger, thereby improving the ability of the first support part 41 and the second support part 51 to adapt to larger size items 100.

[0058] In some examples, multiple rows of second hook portions 52 are provided at the two opposite edges of the stretch paper 50 along the first direction X. When the first hook portion 42 is hooked with the second hook portion 52 at different positions, the overall tightness of the stretch paper 50 can be adjusted so that the stretch paper 50 can be adapted to items 100 of different sizes and shapes, thereby improving the versatility of the item support component 30.

[0059] For example, when the item 100 to be packaged is relatively large, the first hook part 42 can be hooked with the second hook part 52 near the outside, so that the stretch paper 50 is stretched to a relatively low degree and is in a relatively loose state, so as to ensure that the item 100 can be placed between the stretch paper 50 and the paper backing board 40, and to ensure that the stretch paper 50 can stably press against the item 100.

[0060] When the volume of the item 100 to be packaged is relatively small, the first hook part 42 can hook with the second hook part 52 near the inside, so that the stretch paper 50 is stretched to a relatively high degree and is in a relatively taut state, so as to ensure that the item 100 can be placed between the stretch paper 50 and the paper backing board 40, and to ensure that the stretch paper 50 can stably press against the item 100.

[0061] See also some of the possible implementation methods. Figure 2 and Figure 6 As shown, the paper backing board 40 also includes a first folding portion 43. Along the first direction X, the first folding portions 43 are respectively provided on opposite sides of the first support portion 41. A first folding crease 60 is provided between the first folding portion 43 and the first support portion 41. The first folding crease 60 extends along the second direction Y. The first direction X is perpendicular to the second direction Y, and the first folding portion 43 is provided with a first hooking portion 42.

[0062] The first folding portion 43 can be folded relative to the first support portion 41 along the first folding crease 60. For example, the first folding portion 43 can be folded 180° relative to the first support portion 41 along the first folding crease 60. After being folded, the first folding portion 43 can be stacked with the first support portion 41.

[0063] After the stretch paper 50 and the first folded portion 43 are connected via the first hook portion 42 and the second hook portion 52, the first folded portion 43 is folded over. A portion of the stretch paper 50 can be folded over to one side of the first support portion 41 along with the first folded portion 43. The folded first folded portion 43 can form a limiting constraint on the stretch paper 50, making it difficult for the second hook portion 52 of the stretch paper 50 to fall off from the first hook portion 42, reducing the possibility that the stretch paper 50 will separate from the paper liner and lose its limiting constraint ability on the article 100.

[0064] In some examples, the first support portion 41 of the paper backing 40 can be rectangular. The first direction X can be the length direction of the first support portion 41, and the second direction Y can be the width direction of the first support portion 41.

[0065] In some examples, the receiving portion 201 of the paper outer box 20 includes a bottom wall. A second support portion 51 is located on the side of the first support portion 41 facing away from the bottom wall. A first folding portion 43 folds down to the side of the first support portion 41 facing the bottom wall. A first hook portion 42 and a second hook portion 52 are located on the side of the first support portion 41 facing the bottom wall.

[0066] After placing the item 100 on the item support component 30 and inserting the paper outer box 20, the first folded portion 43, the first hook portion 42, and the second hook portion 52, after being folded, can be covered by the first support portion 41. Therefore, when the paper outer box 20 is opened, the first folded portion 43, the first hook portion 42, and the second hook portion 52 are not easily observed, which improves aesthetics. At the same time, the first support portion 41 and the paper outer box 20 can provide a limiting constraint on the first folded portion 43, reducing the possibility of the first folded portion 43 springing back.

[0067] See in some examples Figure 2 and Figure 6 As shown, the paper backing board 40 also includes a second folded portion 44. The second folded portion 44 is provided on at least one side of the first support portion 41 along the second direction Y. A second folding crease 70 is provided between the second folded portion 44 and the first support portion 41. The second folding crease 70 extends along the first direction X. The second folded portion 44 folds over to the side of the first support portion 41 facing the bottom wall. The second folded portion 44 presses against the first folded portion 43.

[0068] The second folded portion 44 can be folded relative to the first support portion 41 along the second folding crease 70. For example, the second folded portion 44 can be folded 180° relative to the first support portion 41 along the second folding crease 70. After folding, the second folded portion 44 can be stacked with the first support portion 41. The first folded portion 43 and the second folded portion 44 can be stacked at the top corner of the first support portion 41. The second folded portion 44 can press against the first folded portion 43, thereby limiting the first folded portion 43 and reducing the possibility of the first folded portion 43 springing back.

[0069] See in some examples Figure 2 and Figure 6 As shown, the first support portion 41 and the paper outer box 20 are integrally formed. A third folding crease 80 is provided between the first support portion 41 and the paper outer box 20. The third folding crease 80 extends along the first direction X. The paper liner 40 is folded into the receiving portion 201 relative to the paper outer box 20.

[0070] The paper liner 40 and the paper outer box 20 can be formed simultaneously from a single paper blank, which helps reduce processing steps and also reduces the assembly steps of the paper liner 40 and the paper outer box 20. The integral molding of the first support part 41 and the paper outer box 20 helps improve the connection strength between the first support part 41 and the paper outer box 20. The first support part 41 can be folded relative to the paper outer box 20 along the third folding crease 80.

[0071] When packaging the article 100, the paper liner 40 is located outside the receiving section 201. After the stretch paper 50 is attached to the paper liner 40 and the article 100 is placed there, the paper liner 40 can be folded over until the paper liner 40, the stretch paper 50 and the article 100 are all inside the receiving section 201.

[0072] In some examples, a second folding portion 44 is provided on the side of the first support portion 41 away from the third folding indentation 80.

[0073] See in some examples Figure 2 and Figure 6 As shown, the paper outer box 20 includes a box body 21 and a lid 22. The box body 21 includes a receiving portion 201. The lid 22 closes or opens the receiving portion 201. The first support portion 41 is integrally formed with the box body 21. A third folding crease 80 is provided between the first support portion 41 and the box body 21. The paper liner 40 is folded into the receiving portion 201 relative to the box body 21.

[0074] When the cover 22 closes the receiving part 201, the box body 21 and the cover 22 cooperate to form an internal environment for containing the article 100. The box body 21 and the cover 22 can isolate the article 100 from the external environment. The box body 21 and the cover 22 can protect the article 100 and reduce the possibility of structural damage to the article 100 due to collision or scratch.

[0075] After hanging the stretch paper 50 on the paper liner 40 and placing the item 100, the paper liner 40 can be folded over until the paper liner 40, the stretch paper 50 and the item 100 are all located in the receiving part 201 of the box body 21. Then, the lid 22 is connected to the box body 21 and the lid 22 closes the receiving part 201.

[0076] See in some examples Figure 2 and Figure 6 As shown, the box body 21 includes a bottom plate 211 and a side plate 212. The bottom plate 211 and the side plate 212 together form a receiving portion 201. The cover 22 is integrally formed with the side plate 212. The first support portion 41 is integrally formed with the side plate 212. A third folding crease 80 is provided between the first support portion 41 and the side plate 212.

[0077] The lid 22, box 21, and paper liner 40 can be formed simultaneously from a single paper blank, which helps reduce processing steps and assembly steps between them. The integral molding of the lid 22, box 21, and paper liner 40 improves the connection strength between the lid 22 and box 21, as well as the connection strength between the first support 41 and box 21.

[0078] For example, the box body 21 includes four side plates 212 connected in sequence. Of the two opposing side plates 212, one side plate 212 is integrally formed with the first support portion 41, and the other side plate 212 is integrally formed with the cover body 22.

[0079] See also some of the possible implementation methods. Figure 3 As shown, the first hook-on part 42 includes hook-on teeth. The second hook-on part 52 includes hook-on holes. The hook-on teeth and hook-on holes are detachably connected by hooking each other.

[0080] When the first hook-up part 42 and the second hook-up part 52 are hooked together, the hook-up teeth can be inserted into the corresponding hook-up holes to connect the stretched paper 50 and the paper backing plate 40. When the first hook-up part 42 and the second hook-up part 52 are separated, the hook-up teeth are pulled out from the hook-up holes to separate the stretched paper 50 and the paper backing plate 40.

[0081] The first hook part 42 and the second hook part 52 each have simple structures and are easy to connect, facilitating the quick assembly or separation of the stretch paper 50 and the paper liner 40, thus improving packaging efficiency. The first hook part 42 and the second hook part 52 are connected by interlocking hook teeth and hook holes, ensuring a stable connection and preventing them from easily detaching. The connection method eliminates the need for additional adhesives, contributing to the overall environmental friendliness of the packaging box 10.

[0082] For example, the number of hook teeth may be equal to or different from the number of hook holes. This application does not impose specific limitations on this.

[0083] For example, one or more hooking teeth may be inserted into a hooking hole, but this application embodiment does not impose specific limitations on this.

[0084] For example, the number of mounting teeth can be greater than the number of mounting holes.

[0085] In some feasible ways, the stretched paper 50 is a paper mesh structure.

[0086] See Figure 7 As shown, multiple rows of slots 90 are cut into the paper blank using a cutter along the first direction X. Each row of slots 90 includes multiple slots 90. The slots 90 in adjacent rows are staggered. When a tensile force is applied to the paper blank along the first direction X, each slot 90 expands and enlarges, allowing the paper blank to be stretched into a stretched paper 50 with a paper mesh structure.

[0087] In some examples, the material of the stretch paper 50 may be, but is not limited to, kraft paper. Multiple rows of slots 90 are cut into the kraft paper along a first direction X using a cutter. The kraft paper is stretched along the first direction X to enlarge the slots 90. The kraft paper is twisted under tension to form the stretch paper 50 with a mesh-like structure. Exemplarily, the thickness of the kraft paper may range from 0.1 mm to 0.3 mm.
