Technical Field

[0001] The present application relates to the technical field of packaging boxes, and in particular to a packaging box for cold chain transportation of fresh food. Background Art

[0002] Cold chain logistics generally refers to a systematic process that ensures refrigerated and frozen foods are kept in a specified low-temperature environment throughout their production, storage, transportation, sales, and consumption to ensure food quality and reduce food loss. Established with advances in science and technology and the development of refrigeration technology, it is a low-temperature logistics process based on freezing technology and leveraging refrigeration techniques.

[0003] Currently, in the cold chain transportation of fresh food, the packaging boxes used have a relatively simple structure, usually insulated foam boxes, and ice packs are placed in the box together with the fresh food to maintain low temperature.

[0004] However, the applicant found that during the cold chain transportation of fresh food, especially during the transportation from the logistics center to the user's location, the ice bags in the packaging box are easily damaged by bumps, and the leakage of liquid in the ice bags will cause the fresh food in the packaging box to be contaminated. Utility Model Content

[0005] In order to keep fresh food fresh at low temperatures while reducing the risk of ice packs being damaged by bumps and causing leakage of liquid therein, thereby contaminating the fresh food in the packaging box, the present application provides a packaging box for cold chain transportation of fresh food.

[0006] The present application provides a packaging box for cold chain transportation of fresh food using the following technical solutions:

[0007] A packaging box for cold chain transportation of fresh food, comprising an outer box, an inner box, and a cold / warm box. The inner box and the cold / warm box are both installed in the outer box, and the cold / warm box is located between the inner and outer boxes. Fresh food can be placed in the inner box, and the cold / warm box is used to keep the fresh food inside the inner box cold.

[0008] Among them, several positioning slots are opened on the inner wall of the bottom of the outer box body, and several positioning strips are installed on the bottom of the cold and temperature box. The positioning strips correspond to the positioning slots one by one. When the cold and temperature box is installed in the outer box body, the positioning strips can be embedded in the positioning slots. A heat-conducting bottom plate is installed at the bottom of the inner box body, and the heat-conducting bottom plate can abut against the upper part of the cold and temperature box.

[0009] Optionally, a gap is left between the edge of the cold-temperature box and the inner wall of the outer box body, and a plurality of buffer pads are provided in the outer box body, and the buffer pads are respectively inserted into the gaps between the outer box body and the cold-temperature box.

[0010] Optionally, longitudinal slots are provided on the outer walls of the inner box body, and corresponding longitudinal strips are installed on each buffer pad. When the inner box body is installed in the outer box body, the buffer pads are slidably embedded in the longitudinal slots through the longitudinal strips and are positioned in contact with the outer walls of the inner box body.

[0011] Optionally, a stabilizing hoop is further provided in the outer box body. The stabilizing hoop is located at the upper part of the inner box body and is encircled by the inner box body. Several fixing grooves are opened circumferentially at the bottom of the stabilizing hoop, and the upper part of each buffer pad can be respectively inserted into the corresponding fixing groove.

[0012] Optionally, each inner wall of the inner box is paved with a moisture-proof cushion layer.

[0013] Optionally, a plurality of lifting straps are installed on the upper portion of the cold-temperature box for taking the cold-temperature box out of or putting it into the outer box.

[0014] Optionally, each inner wall of the outer box is paved with a thermal insulation cushion layer.

[0015] Optionally, the outer box body is provided with a plurality of anti-collision corners, which are embedded and bonded to the corners of the outer box body.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. When the cold / warm box is installed in the outer box, the positioning strip can be snapped into the positioning slot, so that the position of the cold / warm box in the outer box can be fixed, making it less susceptible to damage and leakage caused by bumps during transportation. Since the cold / warm box is located between the inner and outer boxes, the fresh food is placed in the inner box, and the cold / warm box used to keep it cold does not come into direct contact with the fresh food, so that the cold-keeping liquid in the cold / warm box will not flow directly onto the fresh food. This allows the packaging box used for cold chain transportation of fresh food to keep the fresh food fresh at low temperatures while reducing the risk of ice packs being damaged by bumps, causing the liquid inside to leak, and thus contaminating the fresh food in the packaging box.

[0018] 2. The bottom of the inner box is in contact with the upper part of the cold and warm box, and the heat-conducting base plate at the bottom of the inner box can conduct heat efficiently. BRIEF DESCRIPTION OF THE DRAWINGS
