Description

Technical Field

[0001] This utility model belongs to the technical field of packaging cartons, specifically relating to a packaging carton with a multi-layered cushioning structure. Background Technology

[0002] Packaging cartons are paper containers used to protect and transport goods. They are typically made of corrugated cardboard or hardboard and are widely used in logistics, warehousing, and product packaging. They effectively protect contents from impacts, compression, and environmental damage during transport. The design of packaging cartons can be adjusted to meet different needs, including size, shape, and load-bearing capacity, to suit the packaging requirements of various goods. In addition to their protective function, cartons are easy to stack, handle, and store, and also possess certain environmental characteristics because paper is easily recycled and degraded.

[0003] However, existing packaging cartons have few cushioning structures and weak impact resistance. When the middle of each side of the packaging carton is impacted, it is easy to bend, which provides limited protection for the items inside the packaging carton. Utility Model Content

[0004] The purpose of this utility model is to provide a packaging carton with multiple cushioning structures to solve the problems mentioned in the background art, such as the limited cushioning structure of existing packaging cartons, weak impact resistance, and the tendency for the middle of each side of the packaging carton to bend when impacted, thus providing limited protection for the items inside the packaging carton.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a packaging carton with a multi-cushioning structure, including a base and reinforcing edges disposed at the four corners of the base;

[0006] A honeycomb panel is provided between the reinforcing edges, and a box cover is provided on the top of the honeycomb panel and the reinforcing edge;

[0007] The base has inner reinforcing blocks on its four inner sides, two splicing blocks on each inner reinforcing block, plate slots on each splicing block, and splicing interfaces between the two splicing blocks. The bottom inner side of the base has a cross-shaped reinforcing block, and right-angle slots are provided at the four corners of the inner side of the base. The bottom four sides of the inner reinforcing layer have a pair of insert plates, and the top four sides of the inner reinforcing layer have clamping blocks.

[0008] Preferably, the inner reinforcing blocks are respectively bonded and fixed to the right-angle slots. The inner reinforcing blocks are also made of honeycomb cardboard material. The right-angle slots formed by the inner reinforcing blocks and the base together allow the reinforcing edges to be inserted into the right-angle slots.

[0009] Preferably, the splicing block and the inner reinforcing block are bonded and fixed together. The splicing block is made of honeycomb cardboard material, and the cross reinforcing block is also made of honeycomb cardboard material. The cross reinforcing block is formed by folding cardboard.

[0010] Preferably, the cross-shaped reinforcing block can be joined with the splicing interface between the splicing blocks, the cross-shaped reinforcing block can reinforce the middle of the base, and the cross-shaped reinforcing block can improve the overall impact resistance of the base.

[0011] Preferably, the inner reinforcing layer is also made of honeycomb paperboard material, the insert plate is integrally formed with the inner reinforcing layer, and the insert plate can be inserted into the plate slot on the splicing block.

[0012] Preferably, the clamping block is bonded and fixed to the inner reinforcing layer. The clamping block can be inserted into the four sides of the top of the honeycomb panel, and the clamping block can fix the inner reinforcing layer and the honeycomb panel together.

[0013] Preferably, the inner reinforcing layer is an integrated design, the inner reinforcing layer can be folded, and the inner reinforcing layer adopts a hollow design, which can both reinforce the inside of the carton and reduce the overall weight of the inner reinforcing layer.

[0014] Compared with the prior art, this utility model provides a packaging carton with a multi-layered cushioning structure, which has the following beneficial effects:

[0015] By incorporating internal reinforcing blocks, splicing blocks, splicing interfaces, right-angle slots, and cross-shaped reinforcing blocks, the right-angle slot structure formed by the internal reinforcing blocks and the base allows for a secure connection of the reinforcing edges, significantly improving the overall frame stability. The tight adhesion between the internal reinforcing blocks and the right-angle slots enhances the structural strength of the four sides of the base and effectively prevents deformation caused by external impacts. The cross-shaped reinforcing blocks utilize a honeycomb cardboard folding process, which is combined with the interfaces on the splicing blocks to improve the impact resistance of the base bottom and ensure the safety of the packaging during transportation.

[0016] By incorporating an inner reinforcing layer, panel slots, clamping blocks, and inserts, the inner reinforcing layer is securely connected to the panel slots on the splicing blocks via the bottom inserts, while the top clamps hold the outer honeycomb panels, ensuring a tight fit between the inner and outer structures. This significantly enhances the impact resistance of the packaging box. This double-layer cushioning structure provides reliable protection for the contents while optimizing the overall weight through a partially perforated lightweight design, achieving a perfect balance between functionality and practicality.

[0025] This utility model provides, for example Figure 1-6 The packaging carton shown has a multi-cushioning structure, including a base 4 and reinforcing edges 2 disposed at the four corners of the base 4;

[0026] A honeycomb panel 3 is provided between the reinforcing edges 2, and a box cover 1 is provided on the top of the honeycomb panel 3 and the reinforcing edges 2;

[0027] The base 4 has inner reinforcing blocks 9 on its four inner sides, two splicing blocks 8 on its inner reinforcing blocks 9, plate slots 11 on its splicing blocks 8, splicing interfaces 12 between the two splicing blocks 8, cross reinforcing blocks 7 on the bottom inner side of the base 4, right-angle slots 10 on the four corners of the inner side of the base 4, a pair of insert plates 13 on the four sides of the bottom of the inner reinforcing layer 5, and clamping blocks 6 on the four sides of the top of the inner reinforcing layer 5.

[0028] In this embodiment, the packaging carton is a paper container used to protect and transport goods. It is composed of a lid 1, reinforcing edges 2, a base 4, and a honeycomb panel 3. It is widely used in logistics, warehousing, and commodity packaging. It can protect the contents from impact, squeezing, and external environmental influences during transportation.

The combination and use method of the packaging carton is as follows: First, the four reinforcing edges 2 are inserted into the four corners of the base 4. Then, the honeycomb panel 3 can be inserted between two reinforcing edges 2 to form the outer perimeter of the packaging carton. Then, the items can be placed inside the packaging carton. Finally, the lid 1 is closed to complete the packaging of the items, which facilitates subsequent transportation.

[0029] like Figure 3 , Figure 4 and Figure 6 As shown, the inner reinforcing blocks 9 are respectively bonded and fixed to the right-angle slots 10. The inner reinforcing blocks 9 are also made of honeycomb cardboard. The inner reinforcing blocks 9 and the base 4 together form the right-angle slots 10. The reinforcing edge 2 can be inserted into the right-angle slots 10. The splicing block 8 is bonded and fixed to the inner reinforcing blocks 9. The splicing block 8 is made of honeycomb cardboard. The cross reinforcing block 7 is also made of honeycomb cardboard. The cross reinforcing block 7 is made of folded cardboard. The cross reinforcing block 7 can be spliced ​​with the splicing interface 12 between the splicing blocks 8. The cross reinforcing block 7 can reinforce the middle of the base 4. The cross reinforcing block 7 can improve the overall impact resistance of the base 4. The inner reinforcing layer 5 is also made of honeycomb cardboard. The insert plate 13 is integrally formed with the inner reinforcing layer 5. The insert plate 13 can be inserted into the plate slot 11 on the splicing block 8.

[0030] Preferably, by setting up the inner reinforcing block 9, splicing block 8, splicing interface 12, right angle slot 10 and cross reinforcing block 7, the right angle slot 10 formed by the inner reinforcing block 9 and the base 4 can be used to insert the reinforcing edge 2, further ensuring the stability of the reinforcing edge 2. By bonding the inner reinforcing block 9 with the right angle slot 10, the strength of the four sides of the base 4 can be improved, and the base 4 can be prevented from being deformed by bumps. The cross reinforcing block 7 is made of honeycomb cardboard folded. The cross reinforcing block 7 can be inserted into the splicing interface 12 on the splicing block 8 respectively. The cross reinforcing block 7 can improve the impact resistance of the bottom of the base 4.

[0031] like Figure 2 and Figure 5 As shown, the clamping block 6 is bonded and fixed to the inner reinforcing layer 5. The clamping block 6 can be inserted into the top four sides of the honeycomb board 3. The clamping block 6 can fix the inner reinforcing layer 5 and the honeycomb board 3 together. The inner reinforcing layer 5 is an integrated design. The inner reinforcing layer 5 can be folded. The inner reinforcing layer 5 adopts a hollow design, which can both reinforce the inside of the carton and reduce the overall weight of the inner reinforcing layer 5.

[0032] Preferably, through the arrangement of the inner reinforcing layer 5, the board slot 11, the clamping block 6 and the insert plate 13, the inner reinforcing layer 5 is inserted and spliced ​​with the board slot 11 on the splicing block 8 through the bottom insert plate 13. The clamping block 6 on the inner reinforcing layer 5 can clamp the outer honeycomb board 3 from the top. The clamping block 6 can ensure that the inner reinforcing layer 5 and the honeycomb board 3 are in close contact, improving the impact resistance of the packaging carton around the perimeter. At the same time, the double-layer structure can provide a certain buffer for the items inside the packaging carton, ensuring the safety of the items inside. Meanwhile, the inner reinforcing layer 9 adopts a partially hollowed-out design, which can reduce the overall weight of the packaging carton to a certain extent while ensuring strength.
