[0002] Fresh produce logistics refers to the process of delivering fresh food, vegetables, fruits, and other fresh products from their production sites to consumers through specialized supply chain management and logistics technologies. This process involves multiple steps and complex operations, including picking, packaging, storage, transportation, and delivery.

[0003] Fresh produce logistics requires storing sorted products at suitable temperatures, such as in cold storage or quick-freeze cold storage, to prolong their shelf life. This is why fresh produce boxes are used. These specialized containers are used to preserve the freshness of food and fresh produce throughout the cold chain. Their design and materials are designed to maintain optimal temperature and humidity during transportation, extending product shelf life and minimizing waste. They also improve overall logistics efficiency and safety. Whether used for refrigerated transportation or daily food distribution, fresh produce boxes are an essential tool.

[0004] The utility model patent with announcement number CN218142873U proposes a cold chain logistics fresh-keeping box. By providing a support plate frame and elastic members, the device prevents direct contact and collision between food and the inner wall of the fresh-keeping box. Compared with the traditional structure, this device has side support plates that abut against the top of the foam board. At the same time, the cross-axis plate is buckled to the inner wall of the groove of the box cover. The side air curtains are placed inside the placement cavity of the side support plates. After the side air curtains are inflated, they wrap and cushion the food, reducing the impact force of the food during bumps and the chance of quick-frozen food being broken due to collisions, thereby improving the safety of cold chain logistics food during transportation. By providing air bags, food is separated and protected. The device uses a "partition wall" formed by the combination of the frame plate and the air bag to separate and protect the food, preventing collision and breakage between foods during bumps, further improving the safety of cold chain logistics food during transportation. Although the above utility model solves the safety problem of food during transportation, there are still problems such as stacking and overturning between logistics boxes and the single type of food transported during use.

[0032] The present invention is further described in detail below with reference to the embodiments:

[0033] Example 1

[0034] See also Figures 1-10 This embodiment provides a fresh food transportation and preservation logistics box, including a box body 1, an outer shell 10, a slide 101, a box cover 12, a cover plate 120, a slot 121, a baffle 122, a pull rope 123, a closing component 13, a sealing plate 130, a buckle 131, a cold box 2, a drawer 20, a handle 21, a partition 22, a partition 3, an insulation layer 4, and a latch 5.

[0035] The fresh-keeping logistics box for transporting fresh produce includes: at least one fresh-keeping box unit, a latch 5, the latch 5 is fixedly connected to the top of the fresh-keeping box unit, and a socket is provided at the bottom of the fresh-keeping box unit, and two or more fresh-keeping box units are connected to the socket via the latch 5. During the transportation of the fresh-keeping box, the boxes may be stacked on top of each other. The provision of latches and sockets can prevent the boxes from tipping over due to road bumps or turns during transportation, thereby increasing the stability of lightweight stacking. The fresh-keeping box unit includes: a box body 1 and a cold box 2. A slide 101 is provided at the bottom of the box body 1, and the cold box 2 is slidably connected to the slide 101; sliders are fixed at both ends of the top surface of the cold box 2, and the sliders match the shape of the slide 101. The box body 1 includes: an outer shell 10 and two closing components 13. Two closing grooves are provided inside the shell of the outer shell 10, and the two closing components 13 are respectively arranged inside the two closing grooves. The closing groove is located inside the shell 10, and air holes are provided on both sides of the shell 10. The air holes on both sides can be closed by moving the closing assembly 13. In this way, the fresh-keeping box can be used to transport a variety of fresh food. When the air holes are opened, the fresh-keeping box can be used to transport seasonal foods such as fresh fruits and vegetables. When the air holes are closed, the fresh-keeping box can be used to transport aquatic products, meat, etc. The material generally used for the box body 1 is polypropylene, which is a high-density, non-toxic and harmless linear polymer with excellent comprehensive properties. It is often used to make products such as fresh-keeping boxes and disposable packaging boxes. The polypropylene fresh-keeping box is light and durable, has good sealing performance, and is suitable for storing various foods.

[0036] The box body 1 also includes two box covers 12, which are slidably connected to the elongated holes on both sides of the outer shell 10. The length of the elongated holes in the outer shell 10 is greater than the inner diameter of the box body 1. This allows the box covers 12 to be supported on the box body 1 at any point on any side when closed, preventing deformation of the box covers 12.

[0037] The cold box 2 includes: a drawer 20, a handle 21, and multiple partitions 22. The multiple partitions 22 are fixedly connected to the drawer 20, and the handle 21 is fixedly connected to the outside of the drawer 20. The cold box 2 uses the same material as the box body 1. The multiple partitions 22 divide the internal space of the cold box 2 into multiple spaces, so that the ice bags or refrigerants placed in the cold box will not gather in a large amount in one area during transportation, thereby ensuring that fresh food can be cooled evenly. And each partition 22 is provided with a connecting hole. The main function of the connecting hole is: when ice bags or other refrigerants are placed in the cold box 2, cold air can circulate in multiple areas, so that the temperature of the entire cold box is balanced, thereby improving the preservation effect.

[0038] The sealing assembly 13 includes: a sealing plate 130 and a buckle 131. The sealing plate 130 is shaped like two rectangular blocks, one large and one small. The size of the large part is the same as the area where the air vent is opened on the box body 1, and is used to completely seal the air vent. Because the sealing plate 130 is thinner than other parts of the box body, the material used is a material with low thermal conductivity efficiency. Usually, a vacuum insulation panel material can be used. Vacuum insulation panels are a high-efficiency thermal insulation material widely used in construction, home appliances, cold chain logistics and other fields. It is mainly composed of core material, barrier film and getter, among which the core material is the key factor determining its thermal insulation performance. The vacuum insulation panel effectively avoids heat transfer caused by air convection by forming a vacuum layer between the core material and the protective film, thereby significantly reducing the thermal conductivity. For example, a vacuum insulation panel using nanoporous silica as the core material has an extremely high thermal conductivity, which can reach below 0.006W / (m·K), which is 6 times that of traditional EPS boards. In addition, its thermal insulation effect is 5 to 10 times that of traditional insulation materials.

[0039] One end of the buckle 131 is rotatably connected to the sealing plate 130, and a fixing groove is provided on the housing 10, and the other end of the buckle 131 is engaged with the fixing groove. The buckle 131 is in the shape of a "J", and a flat spiral spring is fixed to the end of the buckle 131 connected to the sealing plate 130 to prevent the buckle 131 from rebounding after being fastened. More preferably, an elastic component can be installed on one side of the bottom of the sealing plate 130. When closing is required, the buckle 131 is released and the sealing plate 130 automatically rebounds under the action of the elastic component, thereby closing the vent hole.

[0040] The box lid 12 includes two cover plates 120, a slot 121, two baffles 122, and two drawstrings 123. The slot 121 is fixedly connected to one side of one cover plate 120. The main function of the slot 121 is to allow the two cover plates 120 to fit together when the box lid 12 is closed, preventing them from misaligning. The cover plates 120 can be made of transparent acrylic. This allows the fresh produce inside the box to be viewed during shipment without opening the box lid 12, saving loading time and further reducing transportation costs. The two baffles 122 are fixedly connected to the other side of each cover plate 120 to prevent excessive movement. Two drawstrings 123 are fixedly connected to the outside of each baffle 122. The drawstrings 123 facilitate opening the cover plate 120. To increase the service life of the drawstrings 123, they must be made of a high-strength material, such as steel wire wrapped in plastic or rubber.

[0041] The fresh food transport and preservation logistics box also includes a partition 3; a recess is defined within the drawer 20, and the partition 3 is positioned within the recess. The partition 3 primarily serves to separate the fresh food from the cold box 2. The partition 3 is provided with a plurality of holes. The holes can be of any shape, but should not be too large, as this would easily allow food to enter the cold box 2. Uniformly distributed holes allow the cold air from the cold box 2 to enter the box 1 evenly, thereby enhancing the freshness preservation function.

[0042] The fresh food transport and preservation logistics box further includes an insulation layer 4, which is disposed inside the box body 1 and fits tightly against the inner wall of the box body 1. The insulation layer 4 can slow down the radiation diffusion of the temperature in the box body 1 to the outside.

[0043] The following is a detailed description of the working principle of the fresh food transportation and preservation logistics box.

[0044] like Figure 1-10 As shown, when using the fresh-keeping box, first put ice bags or refrigerant in multiple spaces in the cold box 2, then place the partition 3 in the groove on the cold box 2, further slide the cold box 2 and the box body 1 together, then pull the pull rope 123, open the cover 120, put in the fresh products to be transported, and then decide whether to open the closing component 13 based on the fresh products put in the box body 1, and then put the fresh-keeping box in the position where it needs to be placed. Furthermore, if you want to save space and place multiple fresh-keeping boxes at the same time, you only need to stack the fresh-keeping boxes up and down. The latch 5 on the fresh-keeping box can prevent the stacked fresh-keeping boxes from overturning, thereby improving safety during storage and transportation.

[0045] When the fresh-keeping box is not in use, first open the box cover 12, then take out the fresh food, then separate the cold box 2, remove the partition 3, and remove the refrigerant in the space of the cold box 2.

[0046] When the fresh-keeping box needs to be cleaned, it is only necessary to rinse the entire box, pour out the sewage in the cold box 2, and then clean the cold box 2.

[0047] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
