The heat preservation food packaging box of the preferred embodiment of the utility model is shown in Figure 1, including a hollow base 1, the base 1 is a trapezoidal platform, a cavity for accommodating ice packs is formed in the base 1, and the lower end of the base 1 is provided with a Opening, the middle part of the upper surface of the base 1 is provided with a food tank 11 for placing food, both sides of the upper surface of the base 1 are provided with arc-shaped grooves 12, the arc-shaped grooves 12 communicate with the food tank 11, and the bottom surface of the food tank 11 is provided with There is a through-cooling slot 13 communicating with the inner cavity of the base, and the through-cooling slot 13 can be a rectangular slot arranged in the middle of the food tank 11, or a plurality of arrays arranged on the bottom surface of the food tank 11 with small distribution. hole. Put the food that needs to be refrigerated into the food tank, put the ice pack into the inner cavity of the base, and then place the base in the heat preservation box. The ice pack can cool down the food placed in the food tank through the through-cooling slot 13 and inhibit bacteria The breeding, the curved groove is set on the base and it is also convenient to take food.

As shown in Figure 1-2, the inclination angle of the slope of the base 1 is 10-20 degrees. The base is designed with a beveled edge, which has a beautiful appearance. The beveled edge design is also convenient for the base to be stacked together when no food is placed on the base, saving space and easy to take.

As shown in Figure 1-2, the connection between two adjacent slopes of the base 1 adopts a circular arc transition treatment.

As shown in Figure 1-2, the base 1 is made of plastic; specifically, it may be food-grade plastic such as polycarbonate, polypropylene or polyethylene.

As shown in Figure 3, it also includes an insulation box 2 for accommodating the base 1. The insulation box 2 includes a rectangular bottom plate 21, and the four sides of the bottom plate 21 are connected with vertically arranged side panels 22, and the adjacent side panels are waterproofed. The upper end of any side plate 22 in the four side plates is rotatably connected with a cover 23 for closing the opening.

As shown in Figure 3-4, the side plate 22 and the bottom plate 21 both include a base layer 24, a constant temperature layer 25, a waterproof layer 26 and a drying layer 27 arranged sequentially from the inside to the outside. The side plate 22 is provided with seven layers, and the center layer is The base layer 24 and the constant temperature layer 25 have two layers, and the two layers are respectively arranged on the upper and lower sides of the base layer 24. The waterproof layer 26 also has two layers, which are respectively arranged on the upper and lower sides of the constant temperature layer 25. The drying layer 27 also has two layers , respectively arranged on the upper and lower sides of the waterproof layer 26, the thermostatic layer 25 is made of polyurethane resin, the drying layer 27 is made of tissue paper, and the waterproof layer 26 is made of polyolefin.
