[0030] As Figures 1-2As shown in the figure, this utility model provides a packaging liner, which is mainly used to contain and protect products, such as milk powder cans and bottled health products. The packaging liner includes a liner body 10, which includes a first receiving portion 20, a second receiving portion 30, and an intermediate connecting portion 40 connecting the first receiving portion 20 and the second receiving portion 30. The first receiving portion 20 and the second receiving portion 30 are respectively provided with a forming guide portion 50, a product receiving hole 70, and a fixing connecting portion 60. The forming guide portion 50 is used to guide the first receiving portion 20 and the second receiving portion 30 to fold and form a predetermined angle with the intermediate connecting portion 40. The fixing connecting portion 60 is used to fix the folded first receiving portion 20 and the second receiving portion 30 to the intermediate connecting portion 40. The product receiving hole 70 on the folded first receiving portion 20 corresponds vertically to the product receiving hole 70 on the second receiving portion 30.

[0031] In this embodiment, the inner lining body 10 is divided along its length into a first receiving portion 20, a second receiving portion 30, and an intermediate connecting portion 40 disposed between the first receiving portion 20 and the second receiving portion 30. The intermediate connecting portion 40 serves as a connecting and turning pivot.

[0032] The inner liner body 10 has a planar state and a shaped three-dimensional state. In its shaped three-dimensional state, the inner liner body 10 is a three-dimensional structure with a accommodating space. To enable the planar inner liner body 10 to be folded into a three-dimensional structure with a accommodating space, a forming guide 50 is provided on both the first accommodating portion 20 and the second accommodating portion 30. The forming guide 50 guides the user to fold the first accommodating portion 20 and the second accommodating portion 30 relative to the intermediate connecting portion 40.

[0033] like Figure 1 As shown, multiple molding guides 50 are provided. The molding guides 50 can divide the inner liner body 10 into multiple functional areas, so that the inner liner body 10 can be folded according to a predetermined folding path to form a three-dimensional structure with a specific shape.

[0034] Specifically, by folding along the molding guide 50, the first receiving portion 20 and the second receiving portion 30 can respectively form a predetermined angle with the intermediate connecting portion 40 (e.g., a roughly perpendicular angle or other angle suitable for forming a receiving space), thereby allowing the inner liner body 10 to be folded from... Figure 1 The planar state shown transforms into as follows Figure 2 The structure shown has a specific three-dimensional shape. This design allows the inner liner body 10 to be easily folded from a flat state into a three-dimensional structure, improving the operational efficiency and space utilization of the packaging.

[0035] In order to stably maintain the three-dimensional structure of the inner liner body 10 after folding and forming, a fixed connecting part 60 is further arranged on the first accommodating part 20 and the second accommodating part 30 respectively. The function of the fixed connecting part 60 is to fix and connect the first accommodating part 20 and the intermediate connecting part 40 after the first accommodating part 20 and the second accommodating part 30 are folded and formed according to the guidance of the forming guide part 50 to form a predetermined angle with the intermediate connecting part 40, and to fix and connect the second accommodating part 30 and the intermediate connecting part 40 after the second accommodating part 30 is folded and formed. Through the function of the fixed connecting part 60, it is ensured that the folded inner liner body 10 can maintain a stable three-dimensional shape (as shown in Figure 2 ), which is not easy to scatter or deform, thereby providing reliable support and protection for the products to be packaged.

[0036] When the inner liner body 10 is folded and formed, the first accommodating part 20 and the second accommodating part 30 are in a relative positional relationship. That is, the product accommodating hole 70 on the first accommodating part 20 after folding and forming is corresponding to the product accommodating hole 70 on the second accommodating part 30. This corresponding relationship can be positional alignment, for example, corresponding in the vertical direction, so that when a columnar product (such as a milk powder can) is placed in the inner liner, its two ends can be limited by the product accommodating hole 70 on the first accommodating part 20 and the product accommodating hole 70 on the second accommodating part 30 respectively, thereby achieving effective fixation of the product and preventing the product from shaking, tilting or colliding during transportation or storage.

[0037] In summary, the present embodiment provides a packaging inner liner with reasonable structure, easy to form, stable structure after forming and effective product fixation by arranging the inner liner body 10 (including the first accommodating part 20, the second accommodating part 30 and the intermediate connecting part), the forming guide part 50, the fixed connecting part 60 and the corresponding product accommodating hole 70, which solves the problems of unreasonable packaging structure, poor protection and low space utilization in the prior art.

[0038] In the present embodiment, the inner liner body 10 in the initial state (flat state) is an integrally formed flat structure, for example, made of paperboard, corrugated paper or other suitable sheet materials through die cutting process and the like. Compared with traditional inner liners (such as foamed plastic molded parts, pre-bonded complex paper structures) which are pre-formed and have three-dimensional shapes, the flat structure inner liner can be stacked together when stored, which reduces the volume occupied in the production, storage and transportation links, thereby significantly improving the space utilization and reducing the cost required for transportation and storage.

[0039] In the present embodiment, when the inner liner body 10 is folded and formed from the flat state ( Figure 1 ) to the three-dimensional state ( Figure 2), the first accommodating portion 20 and the second accommodating portion 30 are bent around the intermediate connecting portion 40 to form a predetermined angle, respectively.

[0040] In an embodiment, a handle hole 80 is arranged on each of the first accommodating portion 20 and the second accommodating portion 30, and the handle hole 80 is located on the side of the first accommodating portion 20 and the second accommodating portion 30 away from the intermediate connecting portion 40 after folding and forming.

[0041] In the present embodiment, in order to facilitate the user to take out the inner liner and the product from the packaging box or to facilitate the opening of the inner liner, the packaging inner liner of the present embodiment is further provided with a handle hole 80 on each of the first accommodating portion 20 and the second accommodating portion 30.

[0042] Specifically, as shown in Figure 1 , in the planar state of the inner liner body 10, the handle hole 80 is arranged in the middle region of each of the first accommodating portion 20 and the second accommodating portion 30. When the inner liner body 10 is folded and formed according to the guidance of the forming guide portion 50 (as shown in Figure 2 ), the first accommodating portion 20 and the second accommodating portion 30 form a predetermined angle with the intermediate connecting portion 40, respectively. At this time, the position of the handle hole 80 is on the side of the first accommodating portion 20 and the second accommodating portion 30 away from the intermediate connecting portion 40 after folding and forming. In other words, when the inner liner is folded and formed and placed in the box body 100, the handle hole 80 is in a position that is easy for the user's fingers to reach or contact.

[0043] By arranging such a handle hole 80, the user can conveniently hook the handle hole 80, so as to easily lift the entire inner liner together with the product fixed inside from the box body 100, or assist in the opening operation of the packaging. This design significantly improves the user experience, especially for heavy or not easy to directly grasp product packaging, providing convenience and solving the problem of inconvenience of traditional packaging opening or taking out.

[0044] In an embodiment, at least two product accommodating holes 70 are arranged on each of the first accommodating portion 20 and the second accommodating portion 30, and the product accommodating holes 70 on the first accommodating portion 20 and the product accommodating holes 70 on the second accommodating portion 30 are arranged in an upper and lower relationship after folding and forming.

[0045] In the present embodiment, as shown in Figure 1 , in the planar state of the inner liner body 10, at least two product accommodating holes 70 are arranged on the first accommodating portion 20, and at least two product accommodating holes 70 are also arranged on the second accommodating portion 30. Figure 1 Each part is schematically shown as being provided with two product accommodating holes 70, but this is not a limitation, and more can be provided as needed.

[0046] When the inner liner body 10 is folded and formed, as shown inFigure 2 As shown, the first receiving portion 20 and the second receiving portion 30 form opposing receiving spaces. Crucially, the design of this embodiment ensures that the product receiving hole 70 on the first receiving portion 20 and the product receiving hole 70 on the second receiving portion 30 are vertically opposite each other after folding. For example, if the liner is used to accommodate cylindrical objects such as milk powder cans, after folding, one product receiving hole 70 on the upper first receiving portion 20 will correspond to the upper or top edge of the can, while the corresponding product receiving hole 70 on the lower second receiving portion 30 will correspond to the lower or bottom edge of the can.

[0047] This 70° layout of the product receiving holes, arranged vertically opposite each other, allows the product to be effectively positioned and supported from both above and below. The product is securely "locked" between the corresponding receiving holes, forming a highly stable fixing structure that greatly prevents the product from shaking, tilting, or even tipping over during transportation, handling, or storage, thus providing superior protection. This design is particularly suitable for cylindrical or bottle-shaped products that require stable support.

[0048] In one embodiment, the molding guide 50 includes an indentation line or a fold line.

[0049] In this embodiment, the molding guide 50 can be an indentation line. For example... Figure 1 As shown, these indentation lines are shallow grooves or indentations formed at predetermined folding positions during the manufacturing process of the inner liner body 10 through processes such as molding. These indentation lines constitute the guide path for folding the inner liner body 10. When it is necessary to fold the inner liner body 10 from a flat state, folding along these indentation lines is easier and more precise because the material is easier to bend at the indentation points. By setting indentation lines at appropriate positions on the inner liner body 10, it can be ensured that the inner liner body 10 can be folded according to the predetermined design path, thereby ensuring that the three-dimensional structure formed after folding meets the size and shape requirements.

[0050] In other embodiments, the forming guide 50 may also be a fold line. This fold line can be a pre-defined line on the inner liner body 10 used to indicate the folding position and direction. These fold lines can be printed on the surface of the inner liner body 10 or formed by other physical methods (such as shallow engraving, laser marking, etc.). The fold lines provide the operator with intuitive visual guidance, indicating where and in which direction the fold should be made.

[0051] In the above embodiments, whether adopting indentation lines or fold lines, the core role is to guide the inner liner body 10 to fold along a specific, pre-set path, to ensure accurate and convenient transition from a flat state to the expected three-dimensional structure. The provision of such forming guide 50 not only simplifies the folding operation, improves assembly efficiency, but also helps to ensure the structural consistency and stability of the final formed inner liner, thereby providing reliable support and protection for the product.

[0052] In an embodiment, the product accommodation hole 70 includes a circular hole and / or a polygonal hole.

[0053] In the present embodiment, as shown in Figure 1 and Figure 2 , the product accommodation hole 70 can be a circular hole. The design of the circular hole is particularly suitable for accommodating products with a circular cross-section, such as common milk powder cans, beverage bottles, circular cosmetic bottles, etc. When the product is placed in the inner liner, the edge of the circular hole can form a good fit with the circumferential surface of the product, thereby providing stable support and limiting to prevent the product from shaking.

[0054] In other embodiments, the product accommodation hole 70 can also be a polygonal hole. For example, it can be a square hole, a rectangular hole, a hexagonal hole, an octagonal hole, etc. The design of the polygonal hole is suitable for accommodating products with a corresponding polygonal cross-sectional shape, such as square boxes, hexagonal cylindrical bottles, etc. By matching the shape of the product accommodation hole 70 with the cross-sectional shape of the product, a tighter fit and better fixing effect between the product and the accommodation hole can be achieved, further improving the stability and protection of the package.

[0055] In another embodiment, both circular holes and polygonal holes can be provided on the inner liner body 10. For example, for a combined set that needs to be packaged with cylindrical products and square products, circular holes and square holes can be respectively provided at different positions on the first accommodation part 20 and the second accommodation part 30 to accommodate products of corresponding shapes.

[0056] In summary, by designing the product accommodation hole 70 as a circular hole and / or a polygonal hole, the packaging liner of the present embodiment has wider applicability, can flexibly adapt to the packaging needs of products of different shapes and sizes, and ensures that the product is effectively fixed and supported in the inner liner, preventing unnecessary movement or tilting during transportation or storage.

[0057] In an embodiment, the fixed connection part 60 includes a connection part 61 and an adhesive layer 62 provided on one side of the connection part 61, and the adhesive layer 62 is used to adhere and fix the first accommodation part 20 and the second accommodation part 30 after folding and forming to the intermediate connection part 40, respectively.

[0058] In the present embodiment, as shown in Figure 1As shown, the fixed connecting part 60 comprises a connecting part 61 (for example, a paperboard flap or area extending from the end of the first accommodating part 20 and the second accommodating part 30, respectively) and an adhesive layer 62 arranged on one side of the connecting part 61 (facing the intermediate connecting part 40). In the planar state, the fixed connecting part 60 is provided with two, one at the end of the first accommodating part 20 away from the second accommodating part 30, and the other at the end of the second accommodating part 30 away from the first accommodating part 20. Each fixed connecting part 60 comprises the connecting part 61 and the adhesive layer 62 thereon.

[0059] The adhesive layer 62 can take various forms, such as pre-coated pressure-sensitive adhesive covered with release paper / film, or glue applied during assembly, or double-sided tape, etc.

[0060] When the inner liner body 10 is folded into shape according to the shaping guide 50, the first accommodating part 20 and the second accommodating part 30 form a predetermined angle with the intermediate connecting part 40. At this time, the connecting part 61 (flap) of the fixed connecting part 60 at the end of the first accommodating part 20 will contact a corresponding area of the intermediate connecting part 40, and be fixed by the adhesive layer 62 thereon. Similarly, the fixed connecting part 60 at the end of the second accommodating part 30 is also fixed by the adhesive layer 62 thereon to the corresponding area of the intermediate connecting part 40.

[0061] With the design of the fixed connecting part 60 containing the adhesive layer 62, the folded inner liner parts can be quickly and firmly connected to form a whole, stable three-dimensional structure. This fixing method is simple to operate, without the need for additional buckles or other connecting parts, simplifying the assembly process and structure of the inner liner and reducing production costs. At the same time, this adhesive method also ensures the firmness of the connection, ensuring that the inner liner is not easily deformed or detached during use. Depending on the properties of the adhesive used, it is also convenient for subsequent disassembly and recycling.

[0062] In an embodiment, the connection between the first accommodating part 20 and the intermediate connecting part 40 and the connection between the second accommodating part 30 and the intermediate connecting part 40 are each provided with a vent hole 41.

[0063] In the present embodiment, as shown in Figure 1 and Figure 2As shown, at least one vent hole 41 is provided at the connection between the first accommodating portion 20 and the intermediate connecting portion 40, and at the connection between the second accommodating portion 30 and the intermediate connecting portion 40. Here, the "connection" refers to the folding area on the inner liner body 10 for forming the turning between the first accommodating portion 20 and the intermediate connecting portion 40, and the turning between the second accommodating portion 30 and the intermediate connecting portion 40, i.e. the area along the corresponding forming guide 50 (such as a creasing line or a folding line) or the adjacent area thereof. These vent holes 41 can be designed as elongated strip holes or other suitable shapes.

[0064] The function of these vent holes 41 is to provide an effective venting path for the compressed air when the three-dimensional packaging inner liner (such as Figure 2 As shown) that has been folded and formed is put into a matching external packaging box (such as a box body). Without the venting path, the compression of the air will generate pressure, forming a "air resistance" phenomenon, which makes it difficult for the inner liner to be smoothly pushed into the box body 100. By providing vent holes 41 at the above-mentioned connection (folding area), an effective venting path is provided for the compressed air. The air can flow out through these vent holes 41, thereby eliminating or significantly reducing the air resistance.

[0065] Therefore, the provision of vent holes 41 makes it easier for the packaging inner liner to be put into the box body 100, improves the assembly efficiency on the packaging line, and also improves the operation experience of manual packaging, avoiding the difficulty of assembly or deformation of the packaging due to air pressure problems.

[0066] In this embodiment, when performing a 90-degree or near 90-degree acute angle folding, especially for thicker or harder paperboard materials, the material at the corner will be compressed and stretched. Without the hole, the material may be excessively squeezed at the inner corner, wrinkled or torn at the outer corner. The vent hole 41 removes part of the material, reduces the material volume and stress concentration at the corner, making the folding more smooth, the formed corner more clear and regular, and less prone to breakage or deformation.

[0067] In an embodiment, the first accommodating portion 20 and the second accommodating portion 30 after folding and forming each form a structure comprising a first horizontal portion 91, a second horizontal portion 92, and a vertical portion 93 connecting the first horizontal portion 91 and the second horizontal portion 92.

[0068] In the present embodiment, when the inner liner body 10 is folded according to the guidance of the forming guide 50, the first accommodating portion 20 and the second accommodating portion 30 each form a three-dimensional structure having a specific cross-sectional profile. Specifically, the first accommodating portion 20 and the second accommodating portion 30 each form a structure substantially in the shape of a "U" or a groove after being folded and formed. The structure includes a first horizontal portion 91, a second horizontal portion 92, and a vertical portion 93 connecting the first horizontal portion 91 and the second horizontal portion 92.

[0069] As shown in Figure 2 , for the first accommodating portion 20 located at the upper portion, the first horizontal portion 91 constitutes the bottom surface of the "U" shaped structure, the second horizontal portion 92 constitutes the top surface, and the vertical portion 93 connects the bottom surface and the top surface. For the second accommodating portion 30 located at the lower portion, the first horizontal portion 91 constitutes the top surface of the "U" shaped structure, the second horizontal portion 92 constitutes the bottom surface, and the vertical portion 93 also connects the top surface and the bottom surface. The two "U" shaped structures are oppositely arranged and jointly enclose a space for accommodating products.

[0070] In an embodiment, the product accommodating hole 70 is provided through the upper surface of the first horizontal portion 91.

[0071] In the present embodiment, please refer to Figure 1 and Figure 2 . The first accommodating portion 20 and the second accommodating portion 30 each form a structure including the first horizontal portion 91, the second horizontal portion 92, and the vertical portion 93 after being folded and formed. The product accommodating hole 70 is provided through the upper surface of the first horizontal portion 91 (or directly understood as penetrating the first horizontal portion).

[0072] Specifically, the product accommodating hole 70 is provided on a specific panel area constituting the first accommodating portion 20 and the second accommodating portion 30. When being folded and formed, the panel area provided with the product accommodating hole 70 forms the "first horizontal portion 91".

[0073] Therefore, in the final three-dimensional structure: for the first accommodating portion 20 located at the upper portion, the product accommodating hole 70 is located at the bottom of the "U" shaped structure (i.e. the first horizontal portion); for the second accommodating portion 30 located at the lower portion, the product accommodating hole 70 is located at the top of the "U" shaped structure (i.e. the first horizontal portion).

[0074] When the first accommodating portion 20 and the second accommodating portion 30 are oppositely arranged, the product accommodating hole 70 on the first horizontal portion 91 of the upper structure (the first accommodating portion 20) corresponds to the product accommodating hole 70 on the first horizontal portion 91 of the lower structure (the second accommodating portion 30).

[0075] Such design allows the product (e.g. milk powder can) to pass through the accommodation hole on the top (first horizontal part) of the lower structure (second accommodation part 30), and the bottom of the product can be stably placed on the second horizontal part 92, while the upper part of the product is limited and supported by the accommodation hole on the bottom (first horizontal part) of the upper structure (first accommodation part 20). Two points are formed, which is very stable.

[0076] Figure 3 A schematic view of a packaging box according to an embodiment of the present application is shown in FIG. 1. As shown, a packaging box according to an embodiment of the present application is designed to cooperate with the packaging liner described in the foregoing embodiments to provide a complete packaging solution for products. The packaging box comprises a box body 100, and the box body 100 is provided with the packaging liner according to any of the foregoing embodiments. Figure 3

[0077] In the present embodiment, the box body 100 is usually a shell structure made of paperboard, hardboard or other suitable packaging materials. The shape and internal dimensions of the box body 100 are designed to match the external contour dimensions of the packaging liner according to any of the foregoing embodiments after being folded and formed. Such matching design ensures that the packaging liner can be stably placed inside the box body 100 without significant shaking or displacement.

[0078] When the packaging box according to the present embodiment is used for packaging, the operation process can be as follows:

[0079] The packaging liner in a planar state is taken out; the liner is folded and formed according to the forming guide part 50 (e.g. indentation line) on the liner, and is fixed as a stable three-dimensional structure by the fixed connection part 60 (e.g. adhesive layer); the product (e.g. milk powder can) to be packaged is placed in the product accommodation hole 70 of the liner, and the product is stably fixed in the liner by the corresponding accommodation holes above and below; the entire packaging liner with the product is put into the box body 100 as a whole; and finally the box body 100 is closed.

[0080] When the end user needs to take out the product, the box body 100 can be opened. The user can conveniently take out the entire liner together with the product from the box body 100 by using the handle hole 80, which is very convenient to operate and greatly improves the user experience.

[0081] ​The packaging box of the embodiment, by adopting the structure-optimized and function-perfected packaging inner liner of any one of the foregoing embodiments, and in combination with the box body 100 matched in size, jointly constitutes a complete packaging unit. The packaging box not only can provide reliable fixation and all-around protection for the internal product, prevent the product from being damaged in the transportation and storage process, but also has the advantages of convenient assembly, high space utilization, convenient use by the user, etc. The packaging box is particularly suitable for the packaging of products that need stable protection and are regular in shape, such as milk powder, health care products, cosmetic bottles and cans, etc.

[0082] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
