Description

Technical Field

[0001] This utility model relates to the field of cold chain transportation, specifically a foldable cold storage bag with precise temperature control. Background Technology

[0002] Before Margaret Knight invented the flat-bottomed kraft paper shopping bag in 1870, people used either paper bags or coarse cloth bags when buying goods. After she designed the automatically folding and sealing flat-bottomed kraft paper shopping bag, manufactured the mechanical parts for the bag, and founded the Oriental Paper Bag Company, the flat-bottomed kraft paper shopping bag became widely used for shopping. In daily life, work, and study, people often need to refrigerate and preserve certain items, such as vaccines and biochemical drugs in biological and pharmaceutical products. Therefore, there is a need for a foldable cold storage bag with precise temperature control.

[0003] For example, the foldable cold storage package and double-package composite structure described in (authorization announcement number CN209588484U) solve the problem that the existing plug-in cold storage structure requires constant plugging and unplugging, which is complicated and inefficient. The device includes a package body, and each side of the package body is provided with a cold storage medium bag. The characteristic is that several sides of the package body are provided with creases that can fold the package body into a flat shape. The creases divide the corresponding side of the package body into several independent blocks. Each independent block is a sandwich structure, and a cold storage medium bag adapted to the shape of the corresponding independent block is provided in the sandwich.

[0004] The above-mentioned device can be directly sent into the cold storage for cold storage without disassembling the cold storage medium bag, and will not occupy additional cold storage space. However, the above-mentioned device does not have a device for automatic refrigeration and temperature control of the cold pack, resulting in poor refrigeration effect because the above-mentioned device cannot automatically refrigerate and control the temperature of the cold pack.
