[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1 of the present invention: A special preservation box for storing and transporting raw fish for takeout:

[0030] A special preservation box for storing and transporting raw fish for takeout, the specific structure of which is as follows: Figure 1 As shown, the structure includes a cooling substrate 1, an insulation layer 2, and a hydrogel substrate 3. The cooling substrate 1 includes a protective layer 11 and a cooling medium 12 filled within the protective layer 11. The center of the cooling substrate 1 is recessed downwards to form a groove 13, with the opening of the groove 13 facing upwards. The hydrogel substrate 3 is laid at the bottom of the groove 13 and includes a hydrogel layer 31 and a non-woven fabric layer 32 laid outside the hydrogel layer 31. The sashimi is placed in the groove 13, and the cooling medium 12 around the groove 13 can create a stable cooling environment at the bottom and around the groove.

[0031] Figure 1The two rectangular grooves 13 shown are arranged at intervals along the width direction of the cooling bottom layer 1. However, in other embodiments, the shape of the grooves 13 can be any other shape that can satisfy the placement of fish. The number of grooves 13 can also be one or more. The arrangement of the grooves 13 can also be flexible. The specific shape, number and arrangement of the grooves 13 are flexibly determined according to the size of the cooling bottom layer 1.

[0032] The hydrogel layer 31 possesses excellent water absorption and retention properties. Blood seeping out during the freezing and thawing process of the sashimi is absorbed by the hydrogel layer 31. Compared to placing the sashimi directly in a non-permeable groove, the hydrogel layer 31 keeps the surface of the sashimi dry, reducing microbial contamination. Simultaneously, the hydrogel layer 31 has a large cold capacity. During environmental changes, the hydrogel layer can better balance the temperature within the groove, making it more stable and further reducing the impact of temperature fluctuations caused by environmental changes on the quality of the sashimi. Furthermore, the hydrogel layer 31 also has good cushioning properties, effectively adsorbing and fixing the food during transportation and absorbing some kinetic energy, reducing damage to the appearance and quality of the food caused by mechanical collisions during transport.

[0033] Hydrogel bottom layer 3 can be like Figure 1 As shown, it is only set at the bottom of the groove 13, or it can be like... Figure 2 As shown, it is simultaneously set on the bottom of the groove 13 and the surrounding groove walls.

[0034] The insulation layer 2 completely covers the outside of the cooling base layer 1 and serves to seal the opening in the groove 13. The insulation layer 2 is nested within the cooling base layer 1. The insulation layer 2 is made of aluminum foil insulation cotton, which has excellent heat insulation performance and low cost, and can maintain the temperature stability of the cooling base layer 1 inside. Nesting means that the cooling base layer 1 can be placed inside the insulation layer 2 or flexibly removed from it. Specifically, the top surface of the insulation layer 2 is fixed to other surfaces using zippers, Velcro, snaps, or other detachable connection methods, allowing the top surface to be opened and closed, so that the cooling base layer 1 can be inserted into the insulation layer 2 through the opened top surface. Alternatively, the insulation layer 2 can not be made into a sleeve shape that matches the shape of the cooling base layer 1, but can be directly attached to the outside of the cooling base layer 1 in a wrapping form, with tape used to assist in fixing the wrapping joints. However, both the openable top surface and the directly wrapped insulation layer 2 are existing technologies, and their structures will not be specifically described in this application. Of course, the insulation layer 2 can also be openable on any other side, or more than one side can be openable to meet the embedding requirements of the cooling base layer 1. It is understood that when the insulation layer 2 is directly wrapped around the cooling base layer 1, the insulation layer 2 can also be purchased externally and used in combination with the cooling base layer 1 and the hydrogel base layer 2.

[0035] In other embodiments, the thermal insulation layer 2 can be directly fixed to the corresponding side of the refrigeration base layer 1 by means of adhesion or the like, except for the top surface of the closed groove 13 (the bottom surface and the four side surfaces).

[0036] Of course, it can be understood that in other embodiments, the aluminum foil thermal insulation cotton can also be replaced by other thermal insulation materials disclosed in the prior art.

[0037] In this embodiment, the hydrogel layer 31 is assembled from three biologically friendly materials: natural high molecular peptides, carboxymethyl chitosan, and sodium alginate. Even if it comes into contact with fish, it will not affect the edible performance of the fish. The non-woven fabric layer 32 further separates the fish from the hydrogel layer and tries to minimize or even avoid the consumer's concern that the fish will stick to the hydrogel layer. It can be understood that in other embodiments, the hydrogel layer 31 can also be made of other biologically friendly and food additive raw materials.

[0038] In this embodiment, the refrigeration medium 12 is biological ice, which has high effective cooling capacity, is environmentally friendly, non-toxic, stable in performance and can be repeatedly frozen and thawed. Even if it leaks from the protective layer 11, it will not cause toxicity to the fish in the groove 13. When the protective layer 11 is processed, there is a difference between the upper surface area and the lower surface area, so that after filling the biological ice, the middle part of the refrigeration base layer 1 has a downwardly sunken groove 13.

[0039] Of course, it can be understood that in other embodiments, the biological ice can also be replaced by water or other non-toxic and non-polluting refrigeration media disclosed in the prior art.

[0040] Embodiment two of the fish raw material storage and take-out transportation special fresh-keeping box of the utility model:

[0041] The difference between embodiment two and embodiment one is that it also includes a refrigeration cover layer 4, which is similar to the refrigeration base layer and is also wrapped by a protective layer around biological ice or other refrigeration media. The size of the refrigeration cover layer 4 corresponds to the upper end size of the refrigeration base layer 1 to cover the refrigeration base layer 1. The side of the protective layer of the refrigeration cover layer 4 is fixed together with the corresponding side of the protective layer of the refrigeration base layer 1. Since the protective layer itself is a flexible material (usually a plastic bag), it ensures that the refrigeration cover layer 4 can rotate around the connection to realize opening and closing. The refrigeration cover layer 4 is used to form a stable refrigeration environment above the groove 13.

[0042] In a more preferred embodiment, the end of the refrigeration cover layer 4 away from the rotating connection corresponds to the corresponding position of the refrigeration base layer 1 and is provided with a magnetic buckle 5, which is used to fix the refrigeration cover layer 4 on the refrigeration base layer 1 to prevent the refrigeration cover layer 4 from opening in a bumpy state.

[0043] In other embodiments, the magnetic snaps 5 can also be replaced by Velcro, buckles or other detachable connecting structures. The magnetic snaps 5 can also be omitted, and the position of the refrigeration cover layer 4 is defined by the thermal insulation layer 2 to avoid its opening.

[0044] Embodiment three of the fresh-keeping box for raw fish take-out storage and take-out transportation of the utility model:

[0045] The difference between embodiment three and embodiment one is that the upper end of the refrigeration bottom layer 1 is further provided with a sink section 14, the sink section 14 is located at the mouth of the upper end of the groove 13 and is located at the periphery of the groove 13, the setting of the sink section 14 makes the upper end surface of the groove 13 lower than the upper end surface of the refrigeration bottom layer 1, and the shape and size of the refrigeration cover layer 4 correspond to the shape and size of the corresponding groove 13.

[0046] One side of the refrigeration cover layer 4 is connected to the corresponding side of the sink section 14 in a hinged manner, and the edge of the refrigeration cover layer 4 is supported by the groove bottom of the sink section 14 after being closed, thereby forming a stable refrigeration environment above the groove 13. In this embodiment, the number of refrigeration cover layers 4 corresponds to the number of grooves 13, and each refrigeration cover layer 4 is separately provided on one groove 13, and the opening above each groove 13 on the refrigeration bottom layer 1 can be opened or closed separately.

[0047] Embodiment four of the fresh-keeping box for raw fish take-out storage and take-out transportation of the utility model:

[0048] The difference between embodiment four and embodiment two or embodiment three is that it further comprises a hydrogel cover layer 6, the function and structure of the hydrogel cover layer 6 are similar to those of the hydrogel bottom layer, and the difference is that the non-woven fabric layer completely wraps the hydrogel layer around. The shape of the hydrogel cover layer 6 is adapted to the shape of the groove 13, so that the hydrogel cover layer 6 is placed in the groove 13 before the refrigeration cover layer 4 is closed, covering the raw fish above.

[0049] In this embodiment, the hydrogel cover layer 6 has no connection relationship with other parts, but is an independent part, which is placed in the groove 13 to cover the raw fish during use.

[0050] Embodiment five of the fresh-keeping box for raw fish take-out storage and take-out transportation of the utility model:

[0051] The difference between embodiment five and embodiment four is that the hydrogel cover layer 6 is fixed below the refrigeration cover layer 4, and its position corresponds to the position of the groove 13, so that after the refrigeration cover layer 4 is closed, the hydrogel cover layer 6 is just located in the groove 13.

[0052] Embodiment six of the fresh-keeping box for raw fish take-out storage and take-out transportation of the utility model:

[0053] The difference between the embodiment six and the embodiment four is that the hydrogel cover layer 6 is also one side openably connected to the corresponding side of the recess 13 or the corresponding side of the refrigeration cover layer 4, and the hydrogel cover layer 6 is located below the refrigeration cover layer 4 after being closed.

[0054] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims and not by the above description, and all changes falling within the meaning and range of the equivalent elements of the claims are intended to be embraced in the present application.
