Description

Technical Field

[0001] This utility model relates to the field of corrugated packaging technology, specifically to an integrally molded multi-partition corrugated liner. Background Technology

[0002] With the rapid development of e-commerce and the continuous upgrading of consumer demands, the packaging industry is facing increasing challenges. Especially for the transportation of fragile items, precision instruments, electronic products, and food, sufficient partitions and cushioning are required to prevent damage during transport.

[0003] Corrugated cardboard itself possesses good cushioning and compression resistance, effectively withstanding external impacts and protecting goods from external forces, making it particularly suitable for packaging small to medium-sized goods. The dividing liners in traditional corrugated packaging are primarily corrugated cardboard cutters. These cutters, formed through cutting and folding processes, offer high adaptability and protection. By separating goods, they prevent collisions during transportation, thereby reducing the risk of damage.

[0004] However, corrugated cardboard cutters usually need to be pre-assembled for later use. Therefore, during transportation, the strength of corrugated cardboard is easily reduced due to long-term stacking and weight pressure, and may even be deformed, causing the cutter to fail in its partitioning function. Although the deformation of the cutter during transportation can be reduced by not pre-assembling, on-site assembly during later use will require a lot of manual assembly and may easily lead to the mixing of the various partitions of the cutter, which will further reduce the efficiency of use.

[0005] Therefore, developing an integrated multi-partition corrugated cardboard liner suitable for e-commerce logistics has become key to improving packaging safety, reducing logistics costs, and increasing efficiency. Summary of the Invention

[0006] The purpose of this utility model is to provide an integrally molded multi-partition corrugated liner to solve 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:

[0008] A one-piece molded multi-partition corrugated inner liner is made of corrugated cardboard through die-cutting, creasing, folding and fixing, and includes partition pieces, connecting pieces, folding openings and buckles;

[0009] The connecting piece and the folding opening are square with the same size. The width of the partition piece is the same as the width of the connecting piece. The height of the partition piece is less than the height of the outer packaging box in which it is located.

[0010] The partition pieces are connected sequentially by indentation lines. The partition pieces are directly connected to the connecting pieces at intervals by indentation lines. The partition pieces that are not directly connected to the connecting pieces by indentation lines are detachably fixed by the latches. All the partition pieces are perpendicular to the connecting pieces, and two adjacent partition pieces are perpendicular to each other.

[0011] The latch consists of a pair of latches and latches, which are respectively located at the middle of adjacent sides of the fold.

[0012] Furthermore, before molding, the connecting piece and the folding opening are coaxial and spaced apart from each other.

[0013] Furthermore, before molding, the partition piece is located on both sides of the connecting piece and the folding opening.

[0014] Furthermore, the number of the partition pieces is twice the sum of the number of the connecting pieces and the folding openings.

[0015] Furthermore, the latch extends into the folded opening from the two sides of the connecting piece that are not directly connected to the partition piece.

[0016] The beneficial effects of this utility model are:

[0017] This invention arranges the connecting piece and the folding opening coaxially and at intervals, so that the folding opening is hidden during the folding and compression process, and the partition piece is perpendicular to the connecting piece to form an independent partition space. After being fixed by locking the locking tongue into the locking hole, the three-dimensional state of the multi-partition corrugated lining can be quickly assembled and fixed before use, while unfolded and laid flat during transportation. This can save storage and transportation space, improve the production efficiency of manufacturing enterprises, and improve the self-assembly efficiency of subsequent users.

[0022] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0023] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1-3 As shown, this embodiment discloses an integrally formed multi-partition corrugated inner liner 100, which is formed by die-cutting, creasing, folding and fixing of corrugated cardboard, including partition pieces 1, connecting pieces 2, folding openings 3 and locking buckles 4.

[0028] The connecting piece 2 and the folding opening 3 are square with the same size. The folding opening 3 is a die-cut square notch. After the multi-partition corrugated lining 100 is formed, it is hidden between the connecting piece 2 and the partition piece 1 because it is folded up. Figure 1 As shown in the multi-partition corrugated inner liner 100 molded product, the folding opening 3 is not displayed. The width of the partition piece 1 is the same as the width of the connecting piece 2. This ensures that the partition piece 1 can fit well with the connecting piece 2 after being folded through the folding opening 3. The height of the partition piece 1 is less than the height of the outer packaging box. Depending on actual needs, if another layer of corrugated cardboard is placed on top of the multi-partition corrugated inner liner 100, another layer of multi-partition corrugated inner liner 100 can be added on top of it, as long as the overall height of the multiple multi-partition corrugated inner liners 100 and the separating corrugated cardboard is less than the outer packaging box.

[0029] like Figure 2 As shown, the partition pieces 1 are connected sequentially by indentation lines 5. The partition pieces 1 are directly connected to the connecting pieces 2 at intervals via the indentation lines 5. The partition pieces 1 that are not directly connected to the connecting pieces 2 via the indentation lines 5 are detachably fixedly connected by the latches 4. All the partition pieces 1 are perpendicular to the connecting pieces 2, and two adjacent partition pieces 1 are perpendicular to each other, thereby forming a partition that separates the packaged items.

[0030] The latch 4 consists of a pair of latches 41 and latches 42, each positioned at the midpoint of an adjacent side of the folding opening 3. Specifically, in this embodiment, the latches 42 extend from the two sides of the connecting piece 2 that are not directly connected to the partition piece 1 into the folding opening 3. After the latches 41 are engaged and secured with the latches 42, the multi-partition corrugated liner 100 can be quickly assembled and secured in a three-dimensional state before use, while being unfolded and laid flat during transportation, saving storage and transportation space and improving assembly efficiency.

[0031] like Figure 2 As shown in the planar unfolded structural diagram of the multi-partition corrugated liner 100, before the multi-partition corrugated liner 100 is formed, the connecting piece 2 and the folding opening 3 are coaxial and spaced apart from each other. This allows the folding opening 3 to be compressed and hidden after the multi-partition corrugated liner 100 is formed, thus forming an independent partition space.

[0032] Before molding, the partition piece 1 is located on both sides of the connecting piece 2 and the folding opening 3. The number of partition pieces 1 is twice the sum of the number of connecting pieces 2 and the folding opening 3.

[0033] It should be noted that the multi-partition corrugated liner 100 structure shown in this embodiment has 8 independent partition spaces. If only 4 independent partition spaces are needed, the multi-partition corrugated liner 100 can be achieved by arranging two connecting pieces 2 and one folding opening 3 coaxially and spaced apart from each other, and connecting three consecutive partition pieces 1 on each side. This is also the smallest partition unit.

[0034] 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.
