Description

Technical Field

[0001] This utility model relates to the field of corrugated paper technology, specifically to a corrugated paper transport box with built-in partitions. Background Technology

[0002] In today's booming logistics and transportation industry, the importance of transport packaging is increasingly prominent. Corrugated cardboard transport boxes, with their advantages of being lightweight, low-cost, and recyclable, have become one of the most common packaging methods for transporting goods. However, most existing corrugated cardboard transport boxes lack built-in compartments or have poorly designed compartments, making it impossible to flexibly adjust them according to the specifications and quantity of the transported products. When transporting various items of different sizes, the items are prone to collisions and movement within the box, increasing the risk of damage. Furthermore, unreasonable compartment design leads to wasted space and reduced transport efficiency. Although corrugated cardboard has a certain load-bearing capacity, the structural strength of existing boxes may be insufficient when transporting heavy or fragile items. For example, when transporting large household appliances or glass products, the boxes are easily deformed or damaged when subjected to vibration, collisions, or compression, thus failing to effectively protect the contents. Utility Model Content

[0003] The purpose of this invention is to provide a corrugated paper transport box with built-in partitions to solve the problem of poor partition flexibility in existing technologies mentioned in the background.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A corrugated cardboard transport box with built-in partitions includes a cardboard box shell and partitions installed inside the cardboard box shell in a crisscross pattern. The outer wall of the cardboard box shell is provided with a label area for marking the specifications or instructions of the transported products.

[0006] Each partition baffle is provided with a mounting slide head at its end, and the inner wall of the outer shell of the cardboard box is provided with a fixed slide groove that is the same number as the mounting slide heads, corresponding in position and with interference sliding fit.

[0007] The outer shell of the cardboard box includes a corrugated paper layer and a reinforcing inner core layer disposed in the middle of the corrugated paper layer. Several uniformly and equidistantly arranged transverse frames are installed on the outer walls of both sides of the reinforcing inner core layer.

[0008] The partition baffle includes a reinforced inner core layer and corrugated cardboard disposed on both sides of the reinforced inner core layer.

[0009] Preferably, the length of the horizontal frame is less than the thickness of the corrugated paper layer, and the horizontal frame is embedded inside the corrugated paper layer. Because the length of the horizontal frame is less than the thickness of the corrugated paper layer, it will not protrude from the surface of the box, making the box have a flat and smooth appearance. This not only facilitates the stacking and storage of boxes, reducing the problem of unstable stacking caused by protruding structures, but also improves the aesthetics of the boxes, meeting the transportation needs of some products with high requirements for packaging appearance.

[0010] Preferably, both sides of the corrugated paper layer are provided with a 20-50μm anti-corrosion paint layer, which can effectively block moisture, oxygen, and some corrosive gases in the air from directly contacting the corrugated paper. This can prevent the corrugated paper from softening or becoming moldy due to moisture, oxidation, or corrosion, thereby extending the service life of the carton and reducing packaging costs.

[0011] Preferably, both the fixed slide groove and the mounting slide head have a T-shaped cross-section. When installing the partition baffle, the mounting slide head can smoothly slide into the fixed slide groove, and due to the special T-shaped structure, the mounting slide head will not easily detach within the groove. This connection method effectively prevents the partition baffle from shifting during transportation due to shaking, vibration, or collision, ensuring the stability of the partition baffle's function in separating and protecting the internal items.

[0012] Preferably, the surface of the corrugated cardboard is provided with a protective coating, which provides additional protection and enhances its resistance to external factors. For example, it prevents moisture penetration and resists the adhesion of dust and stains, thereby protecting the contents from moisture, contamination, and other factors, and ensuring the quality of the goods during transportation.

[0013] Preferably, the protective coating is a waterproof oil film layer with a thickness of 15-30μm. This waterproof oil film layer has excellent waterproof performance and can effectively prevent moisture from penetrating into the corrugated cardboard. During transportation, when encountering rain or humid air, the waterproof oil film layer can protect the items inside the cardboard box from moisture, avoiding damage or deterioration caused by dampness.

[0014] Preferably, the top surface of each of the four outer walls of the cardboard box is provided with a concave groove, providing a convenient handhold for workers to handle the box. During handling, workers can insert their fingers into the groove to easily lift the box, avoiding slippage or uneven force caused by gripping the edges, thus improving the safety and efficiency of handling.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: This corrugated cardboard transport box with built-in partitions features a multi-layered composite outer shell composed of corrugated cardboard layers and a central reinforcing inner core layer. Several evenly spaced horizontal frames are installed on the outer walls of both sides of the reinforcing inner core layer, giving the outer shell excellent resistance to pressure and deformation, effectively resisting possible squeezing and collisions during transport. Combined with partitions composed of the reinforcing inner core layer and corrugated cardboard on both sides of the reinforcing inner core layer, the partitions themselves are strong and not easily... The partition baffle is designed to prevent bending and breakage. Simultaneously, the mounting sliders at the ends of the partition baffles correspond in number and position to the fixing grooves on the inner wall of the cardboard box shell, allowing for quick and accurate installation. Once installed, the baffles are stable and not easily loosened, and can be flexibly adjusted according to the specifications and quantity of the transported items, effectively separating and protecting the internal contents. Furthermore, the label area on the outer wall of the cardboard box shell for marking the specifications or instructions of the transported products facilitates quick identification and differentiation of different items by staff, improving transportation and sorting efficiency.

They are only used to facilitate the description of this utility model and to simplify the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Corrugated cardboard transport boxes with built-in compartments, such as Figures 1-3As shown, the device includes a cardboard box outer shell 10 and crisscrossing partition baffles 20 installed inside the cardboard box outer shell 10. The outer wall of the cardboard box outer shell 10 has a label area 30 for marking the specifications or instructions of the transported products. Each partition baffle 20 has a mounting slide head 21 at its end. The inner wall of the cardboard box outer shell 10 has fixed grooves 11, the same number and corresponding positions as the mounting slide heads 21, with an interference fit. The cardboard box outer shell 10 includes a corrugated paper layer 101 and a... The reinforcing inner core layer 102 is located in the middle of the corrugated paper layer 101. Several uniformly spaced horizontal frames 103 are installed on the outer walls of both sides of the reinforcing inner core layer 102. The partition baffle 20 includes the reinforcing inner core layer 201 and corrugated cardboard 202 disposed on both sides of the reinforcing inner core layer 201. A multi-layered composite outer box shell 10 is constructed, consisting of the corrugated paper layer 101 and the central reinforcing inner core layer 102, with several uniformly spaced horizontal frames 103 installed on the outer walls of both sides of the reinforcing inner core layer 102. The horizontal frame 103 arranged at intervals gives the outer shell 10 of the cardboard box excellent resistance to compression and deformation, effectively resisting squeezing and collisions that may be encountered during transportation. Combined with partition baffles 20, which consist of a reinforced inner core layer 201 and corrugated cardboard 202 on both sides of the reinforced inner core layer 201, the partition baffles 20 are strong and not easily bent or broken. Simultaneously, the mounting slides 21 at the ends of the partition baffles 20 correspond in number and position to the fixing grooves 11 on the inner wall of the cardboard box 10, allowing the partition baffles 20 to be quickly and accurately installed inside the cardboard box 10. After installation, they are stable and not easily loosened, and can be flexibly adjusted according to the specifications and quantity of the transported items, achieving effective separation and protection of the internal items. Furthermore, the label area 30 on the outer wall of the cardboard box 10 for marking the specifications or instructions of the transported products facilitates quick identification and differentiation of different items by staff, improving transportation and sorting efficiency.

[0027] Furthermore, the length of the horizontal frame 103 is less than the thickness of the corrugated paper layer 101. The horizontal frame 103 is embedded inside the corrugated paper layer 101. By setting the length of the horizontal frame 103 to be less than the thickness of the corrugated paper layer 101 and embedding it inside the corrugated paper layer 101, the horizontal frame 103 can enhance the structural strength of the outer shell 10 of the cardboard box without protruding from the surface of the cardboard box, thus ensuring the flatness of the cardboard box appearance and avoiding interference with other objects during transportation and stacking due to the protruding structure. At the same time, it also allows the cardboard boxes to be stacked more tightly, saving storage and transportation space.

[0028] The corrugated paper layer 101 has a 20-50μm anti-corrosion paint layer 104 on both sides, giving the outer shell 10 of the cardboard box good anti-corrosion performance. During transportation and storage, when the cardboard box comes into contact with a certain degree of corrosiveness, such as trace amounts of acidic or alkaline substances in humid air, the anti-corrosion paint layer 104 can effectively prevent these corrosive substances from directly contacting the corrugated paper layer 101, thereby extending the service life of the cardboard box and ensuring reliable protection for the transported items inside.

[0029] It is worth noting that both the fixed slide 11 and the mounting slide head 21 have a T-shaped cross-section, making the connection between the partition baffle 20 and the outer shell 10 of the cardboard box more stable. During installation, the mounting slide head 21 can smoothly slide into the fixed slide 11. The T-shaped structure prevents the mounting slide head 21 from easily coming out of the slide, effectively preventing the partition baffle 20 from shifting due to shaking or collision during transportation, and ensuring the stability of the partition baffle 20's function of separating and protecting the internal items.

[0030] Specifically, the surface of the corrugated cardboard 202 is provided with a protective coating 203, which is a waterproof oil film layer with a thickness of 15-30μm, giving the partition baffle 20 a waterproof function. During transportation, if it encounters a humid environment or is accidentally splashed with water, the waterproof oil film layer can prevent moisture from penetrating into the interior of the corrugated cardboard 202, preventing the partition baffle 20 from softening or deforming due to moisture, thereby losing its function of separating and supporting the internal items, and further ensuring the safety of the transported goods.

[0031] In addition, the top surfaces of the four outer walls of the cardboard box 10 are fitted with concave grooves 40, which facilitates the handling of the cardboard box. When the cardboard box needs to be moved, the operator can insert their fingers into the grooves 40 and easily lift the cardboard box without having to search for a suitable gripping position, thus improving handling efficiency and reducing the possibility of damage to the cardboard box due to improper gripping.

[0032] The working principle of this corrugated cardboard transport box with built-in partitions:

[0033] When this corrugated cardboard transport box with built-in partitions is needed, firstly, the staff can flexibly install the partition baffles 20 according to the specifications and quantity of the transported products. The partition baffles 20 are provided with mounting slide heads 21 at their ends, and the inner wall of the cardboard box shell 10 is provided with corresponding fixing grooves 11. The cross-sections of the two are T-shaped and they are interference-fitted. By pushing the mounting slide head 21 along the fixing groove 11, the partition baffles 20 can be securely installed inside the cardboard box shell 10 to form a suitable partition space.

[0034] Before placing the product, the specifications or descriptions of the transported product can be marked on the label area 30 on the outer wall of the cardboard box 10 for easy identification and management later. Then, the product is placed in an orderly manner into the area separated by the partition baffle 20. The partition baffle 20 is composed of a reinforced inner core layer 201 and corrugated cardboard 202 on both sides, and the surface of the corrugated cardboard 202 has a waterproof oil film protective coating 203, which can effectively protect the product. The cardboard box 10 is composed of a corrugated paper layer 101 and a central reinforced inner core layer 102. The reinforced inner core layer 102 has a horizontal frame 103 on both sides, and the corrugated paper layer 101 also has an anti-corrosion paint layer 104 on both sides, making the structure stable and durable.

[0035] Finally, when it is necessary to move the cardboard box, the staff can insert their fingers into the concave grooves 40 in the middle of the top surface of the four outer walls of the cardboard box 10 to easily lift the cardboard box for transportation.
