[0002] Tea cakes, also known as cake tea or round tea, are produced by steaming and pressing tea leaves into round cakes, which greatly facilitates the storage of tea. With the progress of society and the improvement of people's living standards, tea cakes usually need to be packaged when they are sold. Traditional tea cake packaging boxes are mainly divided into metal, plastic, paper and other packaging materials. Among them, paper box packaging has the advantages of low cost, good printing performance, environmental protection and recyclability, and is deeply loved by customers.

[0003] In the prior art, paper tea cake packaging boxes are mostly rectangular packaging boxes, which are usually composed of three parts: a box body, an inner lining frame and a cover, wherein the box body is formed by punching and folding a piece of cardboard, the box body includes a bottom plate, four folding plates arranged on the bottom plate, the four folding plates and the bottom plate together enclose a storage cavity, the inner lining frame is formed by punching and folding a second piece of cardboard, the inner lining frame is placed in the storage cavity, a supporting groove for supporting the tea cake is formed on the inner lining frame, and the cover is formed by punching and folding a third piece of cardboard, and the cover is buckled on the box body.

[0004] However, when producing the above-mentioned packaging box, due to the different structures of the box body, liner frame and cover, different molds are required for the production of the box body, liner frame and cover. Therefore, three production lines are usually required to process and produce the box body, liner frame and cover separately. After that, workers are required to manually assemble the box body, liner frame and cover. The overall production process is relatively cumbersome and the production cost is high, which is not conducive to use. Utility Model Content
