Description

Technical Field

[0001] The utility model relates to the technical field of preservatives, in particular to a box-type preservative. Background Art

[0002] Preservatives are often used to extend the storage time of food and delay the deterioration of food. Some additives achieve the preservation effect by slowing down the growth of microorganisms, while some preservatives are separately arranged in the package and placed in the same space as the food or item to be preserved, creating an environment unfavorable for the survival of microorganisms by deoxidizing or dehydrating, thereby delaying the deterioration of food.

[0003] For example, the Chinese utility model patent document with the publication number CN216187135U discloses a box-type preservative, belonging to the technical field of preservatives, which includes a lower box body and an upper box body. The upper box body is closely attached to the lower box body. A clamping mechanism is installed between the outer walls of the lower box body and the upper box body. Partition plates are fixedly installed on the inner walls of the lower box body and the upper box body. Multiple placement cavities are formed between the partition plates and the inner walls of the lower box body and the upper box body. Multiple through holes are opened on one side of the lower box body and the upper box body away from each other. The through holes are opposite to the placement cavities. A flange is integrally formed on the inner wall of the lower box body close to the upper box body. A sealing groove is opened on one side of the upper box body close to the lower box body. The flange is clamped in the sealing groove.

[0004] In the above document, different types of preservatives can be placed in different placement cavities and separated by partition plates to avoid the mutual reaction and failure of different preservatives. Then, the lower box body and the upper box body are closed and fixed by the clamping mechanism to enhance the packaging stability of the preservative.

[0005] However, the contact area between the preservative and the external environment is small, and it is difficult to exert the preservation effect during application. At the same time, the concentration of the preservative is not conducive to the continuous reaction of the internal preservative. Summary of the Utility Model
