Corrugated carton with vacuum storage chamber

Abstract

The invention provides a corrugated carton with a vacuum storage chamber, and belongs to the technical field of corrugated cartons. The corrugated carton with the vacuum storage chamber comprises a carton body with an opening at the upper end and a closed carton cover matched with the carton body. A vacuum sleeve box is arranged in the carton body, the vacuum storage chamber is arranged in the vacuum sleeve box, and a refrigeration cavity is formed between the periphery of the vacuum sleeve box and the carton body. The closed carton cover comprises a cover body corresponding to the size of the opening in the upper end of the carton body, a closed core block is arranged at the lower end of the cover body, the closed core block is concentric-square-shaped, and the closed core block can be clamped to the upper end of the refrigeration cavity. A vacuumizing end communicated with the vacuum storage chamber is arranged on the cover body. According to the corrugated carton, the spoilage speed of fresh food can be reduced, it is guaranteed that the fresh food is in a fresh state for customers, and the requirements of the customers are met; Refrigerating agents such as dry ice can be filled in the refrigeration cavity between the corrugated carton body and the vacuum sleeve box according to requirements, it is guaranteed that the periphery of the vacuum sleeve box is in a low-temperature state, and the fresh-keeping effect of fresh food is improved.

Description

technical field [0001] The invention relates to the technical field of corrugated cartons, in particular to a corrugated carton with a vacuum storage room. Background technique [0002] With the rise of online shopping, the logistics and distribution industry has developed rapidly. As an important carrier of logistics and distribution, corrugated boxes consume an astonishing amount. [0003] Conventional corrugated boxes can meet most usage occasions. However, in the era of "everything can be purchased online", such as online shopping for fresh fruits and ingredients, it is necessary to use cold chain transportation to ensure the freshness of fruits and ingredients and prevent spoilage. [0004] The existing cold chain transportation mainly uses infrastructure such as refrigerated vehicles and cold storage. However, it is difficult to control the low temperature during the transfer and delivery process. Therefore, it is necessary for the packaging box to bear the responsibil...

AI Technical Summary

Problems solved by technology

[0004] The existing cold chain transportation mainly uses infrastructure such as refrigerated vehicles and cold storage. However, it is difficult to control the low temperature during the transfer and delivery process. Therefore, it is necessary for the packaging box to bear the responsibility of keeping the contents fresh and anti-corrosion, and reducing loss.

[0005] As the main transport packaging material, corrugated boxes are widely used in cold chain circulation. The foam made of polystyrene material is used as the filler to realize the cooling and preservation of corrugated boxes. The disadvantage is that it is difficult to recycle, which is not conducive to recycling.

In addition, the structural strength of conventional corrugated boxes is insufficient, and it is difficult to meet the transportation needs of some valuable food materials, which may easily lead to the loss of value of precious food materials due to extrusion deformation
