The sealing cover 24 of the device can be opened and closed repeatedly to meet the needs of multiple times of taking. An annular groove 27 is provided inside the side wall of the packaging can body 1, and the inside of the annular groove 27 is vacuum-treated. By evacuating the annular groove 27, heat conduction can be significantly reduced. When the device is placed in a freezer for refrigeration, the overall temperature can be reduced. When the user takes the device out of the freezer, the annular groove 27 with a vacuum structure can minimize the loss of temperature inside the packaging can body 1.It ensures that the interior of the packaging can body 1 is continuously in a low-temperature environment, thereby inhibiting the degree of lipid oxidation and microbial reproduction to the greatest extent, reducing pathogenic microbial infection and storage losses, and achieving the purpose of extending the storage period. The inner sides of the ends of the two sealing covers 24 are fixedly connected with a plurality of magnet blocks 28. When the user closes the sealing covers 24, the magnet blocks 28 symmetrically arranged inside the two sealing covers 24 will attract each other, increasing the firmness of the connection between the two sealing covers 24, reducing the gap between the sealing covers 24, further increasing the sealing of the device, and extending the storage period. The lower surface of the inner can 26 is fixedly connected with a rotating rod 29, which is a rod-shaped structure.
