The applicant discovered that when the packaging box needs to contain the packaged items for a period of time, the packaging box needs to be kept in a closed state. When children come into contact with the packaging box, they may open the packaging box by mistake, causing the packaged items in the packaging box to overturn, causing damage to the packaged items, and may also cause damage to children. Therefore, the packaging box needs to be equipped with a locking structure to be used as a child lock. However, the locking structure usually needs to have a reset function to keep the packaging box in a closed state, and the reset function usually needs to be provided with metal springs, plastic buckles and other components. Considering that packaging boxes are usually made of various cardboards, placing components of other materials in them will increase the complexity of the packaging box structure. In addition, components of other materials, such as metal and plastic, are not conducive to the recycling of the cardboard materials of the packaging boxes. Reuse.

In view of the above problems, the applicant proposed a packaging box and cardboard structure. The outer box and the inner box of the packaging box are made of one piece of paper. The structure is simple and convenient to manufacture. At the same time, there is no need to add other material components. Conducive to the recycling and reuse of packaging boxes. In addition, the outer box and the inner box adopt the form of insertion and can slide relative to each other to realize the function of the packaging box to accommodate and protect the packaged items. The lock tongue structure of the inner box is inserted into the first lock mouth of the outer box and the second lock mouth of the inner box. The lock tongue structure of the inner box is bent and connected to the second wall of the inner box, so that the lock tongue structure can remain inserted into the first lock mouth. The state of the lock mouth and the second lock mouth realizes the locking of the packaging box; applying an external force to the lock tongue structure causes the lock tongue structure to deform, which enables the lock tongue structure to withdraw from the first lock mouth and realize the unlocking of the packaging box. Therefore, the packaging box of the embodiment of the present application can simplify the structure of the packaging box, realize the locking and unlocking of the packaging box, and reduce the possibility of children accidentally opening the packaging box on the premise of convenient recycling and reuse.
