Technical Field

[0001] This utility model relates to the technical field of food transportation, and in particular to a packaging carton that facilitates food transportation. Background Technology

[0002] Food transport packaging cartons, also known as food-specific cartons, are paper containers tailored to the characteristics of food and transportation needs. Their design aims to: protect food through reinforced fluting and moisture-proofing, reducing the impact of compression and moisture on quality during transport; standardized dimensions facilitate stacking, saving space and reducing weight, thus lowering transportation costs; use food-grade paper, meeting safety standards to prevent contamination; and utilize low-cost, recyclable paper materials, contributing to environmental friendliness. The core principle is to balance transportation efficiency, cost, and environmental friendliness while ensuring food safety, thereby facilitating food distribution.

[0003] The prior art patent publication number CN112046889A discloses a food packaging carton that is easy to fold, stack, and transport. It includes a carton body, folding side panels on the surface of the carton body, a first cover plate on the surface of the carton body, a second cover plate on the surface of the folding side panels, male and female Velcro fasteners on the surface of the folding side panels, sealing tape on the surface of the second cover plate, damping corner protectors on the bottom surface of the carton body, an opening on the surface of the carton body, and a mounting bracket on the inner wall of the carton body. The beneficial effect is that the food packaging carton proposed in this invention, which is easy to fold, stack, and transport, adds male and female Velcro fasteners to the surface of the folding side panels. After the carton is folded, the folding side panels are folded in half. To prevent the carton from expanding, the male and female Velcro fasteners work together to fix the folded carton, thus reducing the space occupied by the carton.

[0004] Problems identified in existing technologies: Existing food transport packaging cartons have limited moisture-proof performance during use, especially when transported in humid environments, which can easily lead to the food inside becoming damp and spoiling. At the same time, the stacking stability of existing cartons needs to be improved, as they are prone to tipping over during transport and stacking, affecting transportation safety. Utility Model Content

[0006] The outer casing structure consists of an outer shell, handle A, a baffle, a fixing rod, a perforated plate, a limiting rod, and straps. The outer shell has handle A and a baffle on its outer side, and the outer shell is connected to handle A and the baffle. The inner side of the outer shell has a perforated plate and a fixing rod, and the outer shell is fixedly connected to the perforated plate. The outer shell and the fixing rod are connected by threads. A limiting rod is installed within the holes of the perforated plate, and the perforated plate and the limiting rod are connected by threads. Straps are fitted over the outer side of the limiting rod. The holes in the perforated plate, the fixing rod, and the limiting rod are all threaded. The outer shell uses a three-layer corrugated paper structure: an inner layer of food-grade kraft paper, a middle layer of corrugated paper, and an outer layer of moisture-proof kraft paper, bonded together with environmentally friendly adhesive. The fixing rod, perforated plate, and limiting rod are all made of lightweight plastic.

[0007] The inner casing structure consists of an inner shell, a support plate, wear-resistant screws, handle B, partitions, air bladders, a moisture-proof box, and fixing sleeves. The support plate and handle B are located on the outer side of the inner shell, and the inner shell is connected to the support plate and handle B. Wear-resistant screws are installed on the support plate. Several mounting slots are formed on the inner side of the inner shell, and partitions are installed in the mounting slots.

The partitions, casing, and air bladders are connected by Velcro. Moisture-proof boxes are located at the four corners of the inner shell, and the inner shell and moisture-proof boxes are connected by Velcro. Fixing holes are formed on the inner shell, and fixing sleeves are installed in the fixing holes. The inner shell is fixedly connected to the fixing sleeves. The inner shell adopts a three-layer corrugated paper structure: the inner layer is food-grade kraft paper, the middle layer is corrugated paper, and the outer layer is moisture-proof kraft paper. The three layers are bonded together with environmentally friendly adhesive. The fixing sleeves and wear-resistant screws are made of lightweight plastic.

[0008] The beneficial effects of this utility model are as follows: This utility model improves the outer box structure, which consists of an outer shell, handle A, baffle, fixing rod, perforated plate, limiting rod, and straps. The handle A facilitates the handling of cartons by operators, especially during loading, unloading, or short-distance movement, saving effort. The threaded connection between the fixing rod and the inner box structure further enhances the overall connection stability between the outer and inner boxes, preventing relative displacement. The perforated plate has threads inside the holes, allowing adjustment of the limiting rod's installation position on the perforated plate. Combined with the straps on the outside, it provides targeted limiting and fixing for inner boxes or food packaging of different sizes and shapes, improving the adaptability of the outer box to various food packaging and reducing shaking caused by internal gaps.

[0009] This utility model improves the inner box structure, comprising an inner shell, a support plate, wear-resistant screws, handle B, a divider plate, an airbag, a moisture-proof box, and a fixing sleeve. Wear-resistant screws are embedded on the outside of the support plate, preventing the bottom of the inner shell from directly contacting the ground during stacking and transportation, reducing wear and scratches caused by direct bottom contact. It also reduces the risk of moisture directly penetrating the bottom of the inner shell when the ground is damp. Furthermore, the moisture-proof box enhances the overall moisture-proof effect, ensuring the safety of the packed food during transportation. The fixing sleeve is fixedly connected to the inner shell, precisely matching the fixing rod of the outer box to achieve a threaded connection, ensuring a tight fit between the inner and outer boxes, reducing relative displacement caused by bumps during transportation, and improving overall structural stability. The mounting groove of the inner shell and the divider plate are detachably connected, allowing for flexible division of storage areas according to the size and shape of the food, enabling classified transportation, such as separating different types of fruits and pastries to avoid mutual collision and wear; handle B... The design allows for easy extraction of the inner box, eliminating the need to move the outer box when loading, unloading, or retrieving food, thus improving operational efficiency. Airbags on both sides of the partition and the inner box side walls are secured with Velcro, allowing for adjustable inflation based on the characteristics of the food, forming a flexible buffer layer that absorbs impact during transport. This is especially beneficial for fragile foods such as cakes and glass-bottled sauces. The Velcro connection facilitates quick disassembly, replacement, or repositioning of the airbags to suit different cushioning needs. Moisture-proof boxes at the four corners of the inner shell are also secured with Velcro and can contain desiccants, such as silica gel, to specifically absorb moisture inside the box, maintaining a dry environment and preventing food from becoming moldy or softened due to moisture, ensuring food quality and safety during transport.

[0010] This invention utilizes a baffle in the outer shell structure to limit the support plate of the inner shell structure when stacked, making the stacking effect more stable. For irregular food, the device can be inverted so that the outer shell is in contact with the ground and used as the main holding structure. Attached Figure Description

[0014] When using this invention, firstly, adjust the inner box structure according to the type and size of the food to be transported. If transporting different sizes of food, the partition plate 12 can be flexibly installed through the mounting groove on the inner side of the inner shell 8 to divide the interior into multiple independent areas, preventing the food from being squeezed and collided with each other. Next, depending on the fragility of the food, fix the airbags 13 to the Velcro on both sides of the partition plate 12 and the side wall of the inner shell 8, and inflate the airbags 13 with an appropriate amount of gas to form a flexible buffer layer, providing targeted protection for the food. Subsequently, place silica gel desiccant in the moisture-proof boxes 14 at the four corners of the inner shell 8, and fix the moisture-proof boxes 14 with Velcro to absorb moisture inside the box, maintain a dry environment, and prevent the food from getting damp and spoiling.

[0015] After the inner box is prepared, it is placed inside the outer box. At this time, the fixing sleeve 15 on the inner shell 8 is precisely aligned with the fixing rod 4 on the outer shell 1. The two are tightly fixed by threaded connection to avoid relative displacement during transportation. If it is an irregular food, the device can be inverted so that the outer shell is in contact with the ground as the main holding structure. The position of the upper limit rod 6 of the perforated plate 5 can be adjusted. The straps 7 on the outside of the limit rod 6 are used to further limit the food. The straps have no elasticity but can reduce the shaking of the food during transportation.

[0016] During handling, operators can carry the entire carton using the handle A on the outside of the outer shell 1 or the handle B on the outside of the inner shell 8. The operation is convenient and efficient. When stacking and transporting, the baffle 3 of the outer shell 1 will limit the support plate 9 of the inner shell 8. At the same time, the wear-resistant screws 10 on the support plate 9 reduce direct friction with the ground or the lower carton, which not only enhances the stacking stability but also reduces the risk of bottom wear and moisture.
