As shown in fig. 1 to 3, an embodiment relates to a thermal cassette 10 including: a cartridge body 100 and a closure 200. The box body 100 comprises an inner layer 110 which is surrounded and formed with a storage cavity 111, and an outer layer 120 which is connected with the inner layer 110 and arranged outside the inner layer 110, an interlayer 130 which is isolated from the storage cavity 111 is formed between the inner layer 110 and the outer layer 120, and the outer layer 120 is provided with a liquid injection hole 121 which penetrates through the outer layer 120 and is communicated with the interlayer 130; the plugging piece 200 is matched with the liquid injection hole 121 in an opening and closing manner; wherein, intermediate layer 130 is used for storing the heat preservation medium, and the heat preservation medium is used for keeping warm to the article in storing chamber 111.

In the heat preservation box 10, the filling hole 121 can be used for filling the heat preservation medium such as the frozen water and/or the frozen liquid into the interlayer 130, and the plugging piece 200 can plug the filling hole 121 to prevent the heat preservation medium from being heated up due to the absorption of the external heat through the filling hole 121. Storing chamber 111 is used for supplying to eat the material and places, and the heat preservation medium can be to eating the material in the storing chamber 111 and refrigerate heat preservation. When people participate in outdoor activities such as camping and the like, food materials can be put into the storage cavity 111 of the heat preservation box 10, so that the food materials are prevented from going bad.

The plugging member 200 may be a plug for plugging the injection hole 121.

As shown in fig. 1, in one embodiment, the compartment 130 surrounds the storage compartment 111. Therefore, after the heat preservation medium is injected into the interlayer 130, the heat preservation medium can surround the storage cavity 111, so that the contact area between the heat preservation medium and the inner layer 110 is increased, and the heat preservation effect is improved.

Specifically, the inner layer 110 is a square structure, the outer layer 120 is also a square structure, the outer layer 120 is sleeved outside the inner layer 110 and is arranged at an interval with the inner layer 110, and the outer layer 120 is connected with the inner layer 110 through the connecting rib 150. In this way, the interlayer 130 can be enclosed in the storage cavity 111.

In one embodiment, the outer layer 120 is an insulating layer, i.e., the outer layer 120 is made of a foamed insulating material. So, when external environment temperature was too high, outer 120 can slow down external heat transfer and give the heat preservation medium in intermediate layer 130, prevents that heat preservation medium temperature from rising fast to improve heat retaining duration, make the heat preservation effect better.

In one embodiment, the thermal box 10 further comprises a see-through sealing element, a viewing port 140 communicated with the interlayer 130 is further formed between the inner layer 110 and the outer layer 120, and the see-through sealing element is in sealing fit with the viewing port 140. Personnel can see the inside of intermediate layer 130 through perspective sealing member to know the volume of the heat preservation medium of liquid in intermediate layer 130, conveniently annotate the liquid.

In general, when the freezing water is injected into the interlayer 130, the interlayer 130 is not filled to prevent the freezing water from freezing to increase the volume and to break the cartridge body 100.

Further, the perspective sealing element is made of transparent material, and the transparent material can be full transparent material, such as polypropylene, polyvinyl chloride, polystyrene; the transparent material may also be a translucent material, such as low density polyethylene. The see-through seal is used to seal the viewing port 140 to prevent the insulating medium from leaking out of the viewing port 140.

In one embodiment, the see-through seal is a thermally conductive member, for example, the see-through seal may be made of a transparent thermally conductive material such as polypropylene, polystyrene, polyvinyl chloride, or the like. The heat conductive member can guide external heat into the interlayer 130. The heat preservation box 10 can be placed into a refrigerator, and after the heat preservation box 10 is placed into the refrigerator, the refrigerator can cool the heat preservation medium in the interlayer 130.
