[0001] The utility model relates to the technical field of food preservation, in particular to a food preservation cold chain transportation packaging box. Background Art

[0002] Cold chain logistics refers to a systematic project that keeps refrigerated and frozen foods in a specified low-temperature environment during production, storage, transportation, sales, and before consumption, in order to ensure food quality and reduce food loss. It was established with the advancement of science and technology and the development of refrigeration technology. It is a low-temperature logistics process based on freezing technology and refrigeration technology. Conventional food packaging boxes are only used to hold multiple foods to facilitate people to take them and for aesthetic purposes. If you buy boxed foods that need to be refrigerated and kept at a certain temperature, especially when transporting them through a cold chain, the buyer must bring an additional cold-keeping bag to hold the boxed food, or put a refrigerant in the box containing the boxed food to keep it fresh at low temperatures.

[0003] However, when users put food in the packaging box for low-temperature preservation, the ice bag is generally placed in the middle of the inner cavity of the packaging box, but the low temperature can only be maintained for a short time when ice is placed in the middle; and the packaging box is prone to produce water vapor due to the temperature difference between the inside and outside of the packaging box, and the water vapor condenses on the inner wall of the packaging bag. As the water vapor continues to increase, the environment inside the packaging box becomes humid, and bacteria are prone to multiply in a humid environment, which is not conducive to the preservation and storage of food.

[0031] Cold chain logistics refers to a systematic project that keeps refrigerated and frozen foods in a specified low-temperature environment during production, storage, transportation, sales, and before consumption, in order to ensure food quality and reduce food loss. It was established with the advancement of science and technology and the development of refrigeration technology. It is a low-temperature logistics process based on freezing technology and using refrigeration technology as a means. Conventional food packaging boxes are only used to hold multiple foods to facilitate people to take them and for aesthetic purposes. If you buy boxed foods that need to be refrigerated and kept at a certain temperature, especially when transporting them through a cold chain, the buyer must bring an additional cooler bag to hold the boxed food, or put a refrigerant in the box containing the boxed food to keep it fresh at low temperatures.

[0032] However, when users put food in the packaging box for low-temperature preservation, the ice bag is generally placed in the middle of the inner cavity of the packaging box, but the low temperature can only be maintained for a short time when ice is placed in the middle; and the packaging box is prone to produce water vapor due to the temperature difference between the inside and outside of the packaging box, and the water vapor condenses on the inner wall of the packaging bag. As the water vapor continues to increase, the environment inside the packaging box becomes humid, and bacteria are prone to multiply in a humid environment, which is not conducive to the preservation and storage of food.

[0033] Based on this, the technical problems existing in the related art of short low temperature maintenance time and easy generation of water vapor in the fresh-keeping box can be improved, and the embodiments of the present application provide the following solutions.

[0034] The embodiment of the present application provides a food preservation cold chain transportation packaging box, including a flip cover box 10, a zipper assembly 30, a water absorption and cooling assembly 20 and a snap assembly 40;

[0035] The flip box 10 comprises a box body 11 and a flip cover 12 connected by a zipper assembly 30, the inner cavity of the box body 11 and the flip cover 12 form a storage cavity 13; an aluminum foil thickening layer 14 is provided inside the box body 11 and the flip cover 12;

[0036] The water absorption and cooling component 20 includes a support plate 21, an antibacterial buffer pad 22, an ice pack 23 and a shell 24. The support plate 21 is arranged at the bottom of the storage cavity 13. A storage groove 211 is provided at the bottom of the support plate 21. The antibacterial buffer pad 22 is provided on the top inner wall of the storage groove 211. The top of the shell 24 is provided with a groove 241 to place the ice pack 23. The shell 24 is clamped in the storage groove 211 through a clamping component 40. A plurality of through holes 212 are provided on the support plate 21.

[0037] From the above, it can be known that in the food preservation cold chain transportation packaging box provided by the embodiment of the present application, when food is placed in the box body 11 for storage, the food is placed on the support plate 21, the flip cover 12 is closed by the zipper assembly 30, the food is insulated by the aluminum foil thickening layer 14, and the food is kept fresh at low temperature by the ice bag 23. When moisture is generated in the storage cavity 13 due to the temperature difference between the inside and the outside, the antibacterial buffer pad 22 can absorb the moisture in the storage cavity 13 through the through hole 212, and the antibacterial buffer pad 22 is arranged on the top of the ice bag 23, and cooperates with the shell 24 and the aluminum foil thickening layer 14 to absorb the ice bag. 23 is used for heat preservation and insulation, which changes the disadvantage of the short low temperature maintenance time of ice in the middle in the past, and can make the whole package maintain a low temperature environment for a longer time; therefore, the setting of the support plate 21, the antibacterial cushion pad 22, the ice bag 23 and the shell 24 can provide a low-temperature dry preservation environment for perishable food. The antibacterial cushion pad 22 can reduce the probability of condensed water penetrating into the food, making it less likely to affect the flavor and taste of the food, thereby improving the preservation effect. In addition, the antibacterial cushion pad 22, the ice bag 23 and the aluminum foil layer can reduce the growth of spoilage bacteria and mold, and reduce the probability of food spoilage and rot.

[0038] Optionally, in some embodiments, please read Figures 2 to 3 The antibacterial cushion 22 is made of chitosan fiber combined with allicin.

[0039] In this way, chitosan fiber has a large number of hydrophilic groups such as hydroxyl (-OH) and amino (-NH2) on its macromolecular chain, so the fiber has good hydrophilicity and high hygroscopicity. The equilibrium moisture regain of chitosan fiber is generally between 12% and 16%, and its water retention value is about 130% under different forming conditions. Allicin can inhibit and sterilize a variety of microorganisms such as cocci, pertussis Bordetella, diphtheria Bordetella, Escherichia coli, etc., and also has an inhibitory effect on fungal infections, and can even inhibit amoeba, vaginal trichomoniasis, pinworms, etc. Therefore, the antibacterial cushion 22 made of chitosan fiber combined with allicin has a good water absorption and sterilization effect.

[0040] Optionally, in some embodiments, see Figure 3 One side of the antibacterial cushion 22 abuts against the inner wall of the storage groove 211 , and the other side abuts against the ice pack 23 .

[0041] With such arrangement, one side of the antibacterial buffer pad 22 abuts against the inner wall of the storage groove 211, which can facilitate the antibacterial buffer pad 22 to absorb water vapor through the through hole 212, further reducing the probability of water vapor condensation; when placing food, the support plate 21 is forced to move downward, which is easy to cause wear on the ice bag 23. The soft antibacterial buffer pad 22 abuts between the ice bag 23 and the inner wall of the storage groove 211, and has a certain buffering effect, reducing the wear of the ice bag 23; and the antibacterial buffer pad 22 cooperates with the shell 24 to insulate the ice bag 23, which can increase the low temperature maintenance time of the ice bag 23.

[0042] Optionally, in some embodiments, see Figures 2 to 3 A fiber membrane 15 is arranged outside the aluminum foil thickening layer 14 .

[0043] With such arrangement, the food packaging fiber film 15 has a moisture-proof effect, which can prevent the food from absorbing moisture and causing deterioration; during the storage process, the fiber film 15 can effectively prevent the intrusion of water vapor, thereby extending the shelf life of the food; the food packaging fiber film 15 also has an anti-oxidation effect, which can reduce the probability of the oil and other easily oxidizable substances in the food reacting with oxygen. During the packaging process, the fiber film 15 can effectively isolate oxygen and extend the shelf life of the food.

[0044] Optionally, in some embodiments, see Figure 1 to Figure 2 The zipper assembly 30 includes a plurality of zipper tapes 31 and a slider 32. A pair of the zipper tapes 31 are arranged between the box body 11 and the flip cover 12 in cooperation with each other. The slider 32 is arranged at the connection of the pair of zipper tapes 31 in the length direction, and is used to join or separate the zipper tapes 31.

[0045] With such arrangement, when closing the packaging box, the slider 32 is pulled to close the pair of zipper tapes 31 on the box body 11 and the flip cover 12; when opening the packaging box, the slider 32 is pulled in the opposite direction to separate the pair of zipper tapes 31 on the box body 11 and the flip cover 12; therefore, the arrangement of the zipper tapes 31 and the slider 32 facilitates the user to open or close the packaging box.

[0046] Optionally, in some embodiments, see Figures 2 to 4 The support plate 21 is provided with a plurality of recesses 213 , the recesses 213 are conical, and the through holes 212 are provided at the bottom of the recesses 213 .

[0047] With such a configuration, when placing food, the food can be placed in the recess 213. Water vapor is easily condensed on the surface of the food under the temperature difference to produce condensed water. The condensed water flows into the bottom of the recess 213 under the action of gravity and is absorbed by the antibacterial buffer pad 22 through the through hole 212. Therefore, the setting of the recess 213 can preliminarily position the food and facilitate the antibacterial buffer pad 22 to absorb water.

[0048] Optionally, in some embodiments, the snap-on assembly 40 includes a first limit strip 41 and a second limit strip 42 extending along the length direction of the shell 24, the first limit strip 41 is arranged on the inner walls on both sides of the storage groove 211, and the second limit strip 42 is arranged on the side walls on both sides of the shell 24, and the first limit strip 41 and the second limit strip 42 are abutted against each other.

[0049] With such arrangement, when the ice pack 23 or the antibacterial buffer pad 22 needs to be replaced, the shell 24 is tilted up from the storage slot 211, the first limit block abuts against the second limit block, and the first limit block and the second limit block abutting against each other are compressed until the shell 24 is taken out, and the ice pack 23 or the antibacterial buffer pad 22 can be taken out; after placing the new ice pack 23 or the antibacterial buffer pad 22, the storage slot 211 is aligned with the shell 24, the first limit block of the support plate 21 is pressed down to abut against the second limit block, and the support plate 21 is continued to be pressed down, the first limit block and the second limit block are compressed until they are put back into the shell 24 to complete the installation. Therefore, the first limit strip 41 and the second limit strip 42 make it difficult for the ice pack 23 or the antibacterial buffer pad 22 to separate from the support plate 21 during daily use, and it is convenient for the user to replace the ice pack 23 or the antibacterial buffer pad 22.

[0050] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
