The utility model relates to the technical field of cold chain logistics, in particular to a novel flexible phase change cold storage package.
Background
With the improvement of social progress, technological development and living standard of people, the quality requirements of the public on food are more and more strict, and the quality of the food is more and more important. There is a need to enhance research and exploration in cold chain transportation for fresh food storage and transportation. In recent years, refrigeration and freezing are the most commonly used storage and transportation modes, and as the living standard of people increases, refrigerators are popularized in various households, and the transportation modes are more common. The development of refrigeration and refrigerated transport has also led to food products of higher quality. However, since large refrigeration appliances cannot be used from the market to the consumer's home, this has an impact on the quality of the food product. The conventional cold storage agent is not easy to deform after being frozen in daily use, and is easy to damage and reduce efficiency in the use process.
Accordingly, in response to the foregoing problems, it is highly desirable in the marketplace to develop a flexible cold storage agent package that is foldable and flexible, and independently sealed, to maintain the cold storage temperature.
At present, the cold storage agent becomes extremely hard after freezing, and the cold storage agent occupies more transportation volume in the transportation process and even is mutually extruded with food to be punctured, so that the cold storage agent has adverse factors such as poor cold storage effect on the food with larger volume. What is needed in the current market is a flexible coolant package that is efficient, long in maintenance time, and is subject to deformation.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
First embodiment
The novel flexible phase change cold storage packaging bag comprises a bag body 6, wherein cavities 1 which are uniformly distributed are arranged on the bag body 6, and the cavities 1 in the same row are connected with each other through a transverse channel 2;
The cavity 1 at one end of each row of the cavities 1 is respectively connected with a filling channel 7, the inner side of each filling channel 7 is respectively and fixedly connected with symmetrical inclined baffle plates 8, and each pair of inclined baffle plates 8 can prevent the cold storage agent from flowing back.
The outside of each filling channel 7 is respectively printed with a one-way check mark 3.
The lateral sealing lines 4 are printed on the bag body 6 at one side of each filling channel 7.
The cavities 1 are elliptical, and the capacity of each cavity 1 is 15 mL-20 mL.
