DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0026] like Figure 1-5 As shown, a seafood preservation box includes a box body 1 and a box cover 2. The box cover 2 is buckled to the top of the box body 1 by a buckle 8. The material of the buckle 8 is preferably polypropylene, which is not easily damaged during use. It can be well adapted to the working scene of large-scale seafood packaging and is more environmentally friendly than traditional tape sealing.

[0027] In order to ensure the stability and strength of the overall structure of the box body 1 and reduce the space occupied by the box body 1 when placed, the box body 1 is designed as an inverted trapezoidal structure with a large upper part and a small lower part, and the box body 1 is divided into an upper hard part 11, a middle soft part 12 and a lower hard part 13 from top to bottom, and a plurality of folding grooves are arranged on the middle soft part, so that it can be folded, and the box body 1 is compressed as a whole after being folded by vertical pressing, so as to save space. The upper hard part 11 and the lower hard part 13 are preferably made of polypropylene material, which has good anti-collision and collision buffering performance, and has relatively high strength, so as to support and fix the entire box body 1, and enable the box body 1 to withstand possible collisions during transportation and loading; the middle soft part 12 is preferably made of thermoplastic polyurethane elastomer material, which has good thermal insulation performance, is not easy to wear, has certain buffering performance, and is softer than a foam box, which can solve the problem of fish hitting the wall and dying due to excessive shaking during transportation to a certain extent.

[0028] In order to facilitate the use of forklifts to move the fresh-keeping boxes, Figure 1 , 4 As shown, a first groove 3 and a second groove 4 are respectively provided on the bottom surface of the box body 1 along the length direction of the box body 1 and the width direction of the box body 1, and the first groove 3 and the second groove 4 are cross-shaped with each other. No matter how the box body 1 is placed, the fork of the forklift can be inserted into the first groove 3 or the second groove 4, and the fresh-keeping box can be transported.

[0029] like Figure 3 , 5As shown, in order to realize the refrigeration and fresh-keeping function, a connected refrigeration interlayer 5 is provided on the side wall and the bottom of the box body 1, and a support column 16 is provided in the refrigeration interlayer 5 at the bottom of the box body 1. The two ends of the support column 16 are respectively connected to the inner layer of the box body 1 and the outer layer of the box body 1, and then the inner layer of the box body 1 is supported by the support column 16. The support column 16 can be a rigid structure or an elastic structure. A refrigerant that can become a liquid when encountering moisture is provided in the refrigeration interlayer 5. An air inlet 6 connected to the refrigeration interlayer 5 is provided at the upper hard part 11 and the lower hard part 13 of the inner side wall of the box body 1, and a drainage hole 7 connected to the refrigeration interlayer 5 is provided at the bottom of the box body 1. Moisture enters the refrigeration layer through the air inlet 6, and the refrigerant becomes a liquid when encountering moisture and then refrigerates. The formed liquid is finally discharged through the drainage hole 7, and after being discharged, it is collected and dried for reuse.

[0030] In this embodiment, the refrigerant is sodium polyacrylate gel, and its raw materials (per 100 ml of refrigerant) include sodium polyacrylate (60%), sodium tripolyphosphate (5%), deionized water (35%), ethanol: 50 ml, pure water: 50 ml, glycerol: 5 ml, biological glue powder: 2 grams (generally chitosan). The production steps are: first add 60% sodium polyacrylate powder into a beaker, then add 5% sodium tripolyphosphate powder, stir evenly with a glass rod, then slowly add 35% deionized water into the container and stir continuously until the mixed liquid in the container becomes a uniform diluent; filter the mixed liquid, and then place it at room temperature for a period of time. Take out 50 ml for use. Then prepare a clean beaker, pour ethanol, pure water and glycerin into the beaker according to the formula ratio, and stir evenly; then add the weighed sodium polyacrylate and biological glue powder into the beaker in turn, and stir thoroughly after each addition until there is no granular matter; pour the prepared mixture into a cooling container and place the container in a ventilated and dry place, waiting for the refrigerant to completely dry and solidify; when the refrigerant is completely dry, take it out and place it in a moisture-proof protective box.

[0031] For further insulation, Figure 2 , 5 As shown, a sealing strip 9 is provided at the joint between the top of the box body 1 and the box cover 2, so that the cold air is not easy to overflow and the heat is kept for a long time. In addition, a heat-insulating layer 15 is also provided on the bottom surface of the box cover 2. The heat-insulating layer 15 and the sealing strip 9 are preferably made of thermoplastic elastomer material, which can increase the friction between the box cover 2 and the box body 1 while achieving heat preservation, so that the box cover 2 is not easy to fall off.

[0032] like Figure 1As shown, buckle grooves 10 are provided on the side walls opposite to the upper hard part 11 for easy manual carrying of the fresh-keeping box, and a handle 14 is provided on the top of the box cover 2 for easy hand-carrying of the fresh-keeping box. Considering the human body structure during the carrying process, the arms can be extended but the arm length cannot be increased, so the buckle grooves 10 are provided on the side walls of the box body 1 in the width direction.

[0033] Based on the above structure, the fresh-keeping box of the utility model has been greatly improved in functionality and practicality, and has the following advantages:

[0034] 1. Environmental protection: PP, TPU, and TPE are all environmentally friendly materials, and are not traditional foam materials. They are not easy to degrade and are prone to white pollution and new types of microplastic pollution. In addition, the current ice packs need to be frozen in the refrigerator before use, which consumes electricity. In addition, when packaging the foam box, it needs to be wrapped with tape, but ours only needs to be buckled 8, and the tape is not very environmentally friendly.

[0035] 2. Recyclability: The box can be folded, similar to a compressed washbasin, and can be recycled after one use. When recycled, it is compressed and recycled to reduce the space occupied, increase the number of recycled transportation, and complete the transportation in one time. Although the traditional foam box is waterproof, its performance is not very good, and it is easy to get dirty and difficult to clean. The material used in this utility model has good waterproof performance. If it gets dirty, it can be rinsed to remove the stains.

[0036] 3. Not easy to be damaged: The material used in the box body 1 and other structures has higher strength than foam, especially the TPU material of the main part of the box, which has good shock absorption and anti-collision performance.

[0037] 4. Refrigeration performance: Through the interlayer refrigeration technology, compared with traditional ice bags, it can be reused and does not need to be frozen. It uses the moisture in the seafood transportation process to absorb moisture and refrigerate. The traditional foam box only has the insulation function, and the refrigeration function requires additional ice bags to increase the weight. The fresh-keeping box of this utility model integrates the insulation and refrigeration functions.

[0038] Finally, although the above description has shown and described the embodiments of the present invention, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
