[0002] With the rapid development of e-commerce and logistics, packaging cartons, as the most common transportation and storage containers, have received widespread attention for their protective performance. Traditional packaging cartons are usually made of corrugated cardboard and mainly provide basic physical protection. However, in actual warehousing and transportation, cartons face the following prominent problems: moisture can gradually penetrate into the interior through the carton walls, causing the contents to become damp. Therefore, we have made improvements to this issue and proposed a packaging carton structure with a moisture-proof and shock-proof lining. Summary of the Invention

[0003] This invention provides a packaging carton structure with a moisture-proof and shock-proof inner liner, including a packaging carton body. The packaging carton body is provided with a first moisture-proof and shock-proof inner liner and a second moisture-proof and shock-proof inner liner located on top of the first moisture-proof and shock-proof inner liner. A product storage space is formed between the first moisture-proof and shock-proof inner liner and the second moisture-proof and shock-proof inner liner. When packaging, the product is placed in the storage space, and the packaging carton body, the first moisture-proof and shock-proof inner liner, and the second moisture-proof and shock-proof inner liner work together to protect the packaged product.

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] For an example, please refer to... Figures 1-11A packaging carton structure with a moisture-proof and shock-proof inner lining includes a packaging carton body 1, a first moisture-proof and shock-proof inner lining 2 and a second moisture-proof and shock-proof inner lining 3 located on top of the first moisture-proof and shock-proof inner lining 2, forming a product storage space between the first moisture-proof and shock-proof inner lining 2 and the second moisture-proof and shock-proof inner lining 3. The product is placed in the storage space during packaging, and the packaging carton body 1, the first moisture-proof and shock-proof inner lining 2 and the second moisture-proof and shock-proof inner lining 3 work together to protect the packaged product. The packaging carton body 1 is made entirely of waterproof corrugated paper. Waterproof corrugated paper refers to corrugated cardboard that has been surface treated, such as laminating, coating, waxing or applying waterproofing agents, to enhance its moisture-proof and water-repellent properties. The outer packaging carton body 1 provides basic dustproof, impact-proof, and shaping protection. The first moisture-proof and shockproof inner lining 2 and the second moisture-proof and shockproof inner lining 3 specifically undertake moisture-proof, cushioning, and shockproof functions. The first moisture-proof and shockproof inner lining 2 and the second moisture-proof and shockproof inner lining 3 together form a closed product storage space, avoiding direct contact between the product and the packaging carton body 1, effectively isolating external moisture and cushioning external impacts.

[0020] Furthermore, the first moisture-proof and shock-proof liner 2 includes a first foam block 21 and a second foam block 22 connected to one side of the first foam block 21. The second foam block 22 and the first foam block 21 are foamed into a whole in the same mold using EPP materials of different densities, rather than being glued together. This design can improve strength. Traditional glued splicing structures are prone to problems such as delamination, cracking, and deformation of gaps. However, the integrated mold foaming molding creates a whole structure without splicing gaps and with a firm connection. At the same time, the composite molding of EPP materials of different densities can combine the advantages of high strength and deformation resistance of high-density EPP with the dual advantages of high cushioning and high toughness of low-density EPP. A first storage cavity is provided between the top of the first foam block 21 and the second foam block 22. The first storage cavity is used for the placement and positioning of the bottom of the product, reducing the horizontal displacement and shaking of the product.

[0021] Furthermore, a first filling board 23 is placed on the side of the first storage cavity near the second foam block 22. The first filling board 23 is made by folding and gluing a piece of corrugated cardboard. A second filling board 213 is placed on the side of the first storage cavity near the first foam block 21. The arrangement of the first filling board 23 and the second filling board 213 can fill the gap between the first storage cavity and the bottom of the product, improve the fit and stability of the product placement, and enhance the cushioning and protection effect.

[0022] Furthermore, the first foam block 21 has a second side groove 25 on its side, and the second foam block 22 has a first side groove 24 on both sides of the side away from the first foam block 21. Foam board 211 is provided in both the first side groove 24 and the second side groove 25, and corrugated board 212 is provided inside the foam board 211. The composite structure of foam board 211 and corrugated board 212 embedded in the first side groove 24 and the second side groove 25 enhances the shock absorption and compression resistance of the side of the first moisture-proof and shock-proof inner lining 2.

[0023] Furthermore, a third side groove 26 is provided on the side of the first foam block 21 away from the second foam block 22. A first waterproof corrugated board 28 and a second waterproof corrugated board 29 are placed in the third side groove 26. The first waterproof corrugated board 28 is bonded to the inner side of the second waterproof corrugated board 29 with hot melt adhesive. A buffer paper tube 27 is also provided in the third side groove 26. The buffer paper tube 27 is located on one side of the first waterproof corrugated board 28 and the second waterproof corrugated board 29. The first waterproof corrugated board 28 and the second waterproof corrugated board 29 are bonded together by hot melt adhesive, with good adhesion and sealing, and no air or water gaps. At the same time, the cylindrical buffer paper tube 27 has excellent pressure resistance and cushioning performance, which can absorb vibration and extrusion impact, and improve the shockproof effect.

[0024] Furthermore, a fourth side groove 214 is provided at one of the corners of the first foam block 21 away from the second foam block 22. An L-shaped protective plate 210 is provided on the inner wall of the fourth side groove 214. The L-shaped protective plate 210 embedded in the fourth side groove 214 can specifically enhance the protection capability of the corner position.

[0025] Furthermore, the second moisture-proof and shock-proof liner 3 includes a third foam block 31 located on top of the first foam block 21. The third foam block 31 is provided with a sixth side groove 33. The inner wall of the sixth side groove 33 is inserted into the outer surface of the first waterproof corrugated board 28. The insertion-type limiting can realize the alignment and installation of the second moisture-proof and shock-proof liner 3 and the first moisture-proof and shock-proof liner 2, limit the horizontal displacement of the third foam block 31, and reduce the situation of offset and misalignment.

[0026] Furthermore, the third foam block 31 is provided with an eighth side groove 37, and the inner wall of the eighth side groove 37 is inserted into the inner side of the L-shaped guard plate 210 to improve the limiting effect on the third foam block 31.

[0027] Furthermore, a fifth side groove 32 is provided on the side of the third foam block 31. The inner wall of the fifth side groove 32 is inserted into the foam board 211 in the second side groove 25. A fourth foam block 34 is provided on one side of the third foam block 31. A fifth foam block 35 is provided on the side of the fourth foam block 34 away from the third foam block 31. The fourth foam block 34 is located on top of the first foam block 21, and the fifth foam block 35 is located on top of the second foam block 22. The fifth foam block 35 and the fourth foam block 34 are foamed into a whole in the same mold using EPP materials of different densities, rather than being bonded together. This arrangement can improve the strength.

[0028] Furthermore, a seventh side groove 36 is provided on the side of the fifth foam block 35 away from the fourth foam block 34. The inner wall of the seventh side groove 36 is inserted into the foam board 211 in the first side groove 24, which further improves the stability between the first moisture-proof and shock-proof lining 2 and the second moisture-proof and shock-proof lining 3.

[0029] Open the top cover of the main body 1 of the packaging carton. Embed foam board 211 with corrugated board 212 in the first side groove 24 and the second side groove 25. Install cushioning paper tube 27, first waterproof corrugated board 28 and second waterproof corrugated board 29 in the third side groove 26 in sequence. Fix L-shaped protective plate 210 in the fourth side groove 214. Then place the first filling board 23 and the second filling board 213 on both sides of the first storage cavity. After completing the assembly, place the first moisture-proof and shockproof inner liner 2 flat on the main body of the packaging carton. Next, place the product to be packaged stably inside the first storage cavity of the first moisture-proof and shock-proof inner liner 2. Then, align the second moisture-proof and shock-proof inner liner 3 with the top of the product. Insert and align the sixth side groove 33, the eighth side groove 37, the fifth side groove 32, and the seventh side groove 36 with the corresponding parts of the first moisture-proof and shock-proof inner liner 2 so that the second moisture-proof and shock-proof inner liner 3 fits and covers the top of the product. Fold and close the top cover of the packaging carton body 1 to complete the overall packaging of the product. It can then be directly stacked, handled, transported, and stored.
