Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cold chain distribution, and in particular to an insulation box used for cold chain distribution. Background Art
[0002] Insulation boxes are often made of high-foam polypropylene for mold injection foaming, and are sealed with a lid to slow down the heat exchange inside and outside the box. Insulation boxes are often used in scenes such as refrigerated goods delivery, camping in the suburbs, or takeout delivery; however, most of the insulation boxes with long insulation time on the market are generally heavy, and lighter insulation boxes generally have shorter insulation time. There is no relatively light insulation box with a long insulation time.
[0003] The insulation box is made of high-foam polypropylene material injection molding. Since the surface is not smooth, there are tiny micropores on the box wall. When the food soup in the insulation box is bumped or hit and leaks, the tiny micropores are easily soaked with food juice or oil stains, which are not easy to rinse clean. Some insulation boxes have fabric sewn on the surface. If food soup, oil stains or dust soak into the surface of the fabric, the dirt on the surface of the fabric will be difficult to rinse clean.
[0004] In addition, since the high-foam polypropylene insulation box is formed by foaming material, the surface or corners of the insulation box are prone to damage after a certain period of use or when the insulation box is scratched; most of the existing insulation box bodies are one-piece molding designs, which are not easy to repair after damage. If repair is required, the entire package must be returned to the factory for unpacking and repair, which will incur large logistics and labor costs.
[0005] Biological products or blood products have high insulation requirements for thermal insulation boxes. If the temperature inside the box is too high, it will easily lead to the deterioration of biological products or blood products. Secondly, some seafood or cold drinks also have high insulation requirements. If the temperature inside the box is too high, it will easily lead to the deterioration of seafood or the change of the taste of cold drinks. Refrigerants are often placed in some thermal insulation boxes to meet the cold chain transportation needs of the thermal insulation boxes; however, the existing refrigerants are generally placed at the bottom of the box, which leads to low temperature at the bottom of the box, high temperature at the top of the box, uneven temperature inside the box, and a certain temperature difference; the temperature inside the thermal insulation box is also not easy to monitor, and it is not easy to detect when the temperature inside the thermal insulation box is too high. Therefore, it is a problem that technicians in this field need to solve to provide a thermal insulation box for cold chain distribution that is light in weight and has a long insulation time, monitors the temperature inside the thermal insulation box in real time, reminds the delivery personnel when the temperature is too high, is easy to clean, and is easy to repair after damage.
