By separating the independent spaces for placing the ice bags at the two ends of the main box body 1, the influence of the ice bag condensed water on cakes can be reduced; by placing the ice bag in the ice bag box 4 for releasing the cold energy, the condensed water can be isolated, and the overflow of the four places can be avoided.

Specifically, as shown in fig. 6, the ice bag case 4 includes a main case body and a case cover 401, the main case body is in a flat cuboid shape and is provided with an opening at the top, the case cover 401 is detachably mounted on the opening at the top of the main case body, and the ice bag is contained in an inner cavity of the main case body.

Specifically, as shown in fig. 3 and 6, the main box body is provided with ventilation holes 402 on a side facing the storage cavity 5, and the ventilation holes 402 are regularly arranged.

The box cover 401 is detachably buckled on the top opening of the main box body, so that the ice bag in the box body can be reused after being replaced; by the provision of the ventilation holes 402, the release of the cooling capacity toward the storage chamber 5 is facilitated.

In a specific implementation manner of this embodiment, a sponge cushion layer is disposed on the inner bottom surface of the main box body. Further, a sponge cushion layer is arranged on the narrow side surface in the main box body and the lower surface of the box cover 401.

Through set up the sponge bed course in the interior bottom surface of main box body, when main box body 1 opening up square, the water droplet of condensation on the ice bag drips on the sponge bed course of bottom surface, avoids its transportation to jolt and overflow. By arranging the sponge cushion layer on other surface walls, even if the main box body 1 is placed upside down or sideways by misoperation, the water drops can be absorbed by the sponge cushion layer.

The cold chain packaging structure of the cream cake of this embodiment is different from that of embodiment 1 in the process of loading, in that an elongated ice bag is loaded into the main body of the ice bag housing 4, and the cover 401 is fastened, the ice bag housing 4 is inserted into the ice bag chamber 6, and the air holes 402 are noted to face the storage chamber 5.

According to the cold chain packaging structure of the cream cake, the inner cover 2 and the outer cover plate 3 are arranged on the opening at the top of the main box body 1, so that the sealing performance of an inner cavity can be improved, the leakage condition is reduced, the cold chain transportation quality is improved, and the quality of foods is ensured. In addition, the inner cover 2 is made of a plastic plate with good flexibility, has better shock resistance compared with a foam box plate, and can continuously play a role in cold sealing even if the outer cover plate 3 is cracked and damaged; by providing the weather strip 201 to be pressed against the bottom surface of the step 102, the sealing performance can be increased by utilizing the elastic deformation of the rubber weather strip. By separating the independent spaces for placing the ice bags at the two ends of the main box body 1, the influence of the ice bag condensed water on cakes can be reduced; by placing the ice bag in the ice bag box 4 for releasing the cold energy, the condensed water can be isolated, and the overflow of the four places can be avoided. The box cover 401 is detachably buckled on the top opening of the main box body, so that the ice bag in the box body can be reused after being replaced; by the provision of the ventilation holes 402, the release of the cooling capacity toward the storage chamber 5 is facilitated. Through set up the sponge bed course in the interior bottom surface of main box body, when main box body 1 opening up square, the water droplet of condensation on the ice bag drips on the sponge bed course of bottom surface, avoids its transportation to jolt and overflow. By arranging the sponge cushion layer on other surface walls, even if the main box body 1 is placed upside down or sideways by misoperation, the water drops can be absorbed by the sponge cushion layer.
