[0043] Reference Figures 1 to 8 , the packaging box of the utility model is exemplified with several embodiments.

[0044] As Figures 1 to 8 indicated, the packaging box 100 of the utility model embodiment comprises a box body 200 and a cover body 300, the box body 200 is hollowly formed with a storage cavity 210 with an opening facing upward, and articles are arranged in the storage cavity 210. The cover body 300 comprises a fixed cover 310 and a movable cover 320 rotatably connected, and the fixed cover 310 and the movable cover 320 are respectively clamped and connected with the box body 200, and in use, people can open the movable cover 320 alone to take the articles in the storage cavity 210.

[0045] In the embodiment, the fixed cover 310 and the movable cover 320 are provided with a folding line 400 and a connecting piece 500 at one end close to each other.

[0046] It can be understood that the fixed cover 310 and the movable cover 320 are rotatably connected through the folding line 400, as Figure 4 indicated. The folding line 400 is a rotating groove 410 recessed inward along the inner top surface of the cover body 300, as Figure 5 , Figure 6 and Figure 8 indicated, the rotating groove 410 extends along the front and back directions, so that the thickness of the cover body 300 corresponding to the folding line 400 is relatively thin, and the fixed cover 310 and the movable cover 320 can be relatively rotated.

[0047] In use of the packaging box 100, the fixed cover 310 is always clamped and connected with the box body 200, when the movable cover 320 is rotated along the folding line 400 to open relative to the fixed cover 310, the cover body 300 is in an open state, as Figure 4 indicated, the packaging box 100 is also in an open state, at this time, the included angle between the movable cover 320 and the fixed cover 310 is greater than 0 degrees and less than 180 degrees, and people can take the articles from the storage cavity 210 through the opening corresponding to the movable cover 320.

[0048] When the movable cover 320 is rotated to close relative to the fixed cover 310 along the folding line 400, the cover body 300 is in a closed state, as shown in Figures 1 to 3 The packaging box 100 is also in a closed state at this time, and the included angle between the movable cover 320 and the fixed cover 310 is 180 degrees. The movable cover 320 and the fixed cover 310 are horizontally opposite, and the articles are stably placed in the storage cavity 210.

[0049] In this embodiment, the folding line 400 extends in the front-rear direction, and the fixed cover 310 and the movable cover 320 are arranged in the left-right direction.

[0050] It can be understood that the connecting piece 500 is provided with two and is located at both ends of the folding line 400, that is, the two connecting pieces 500 are located at the front end and the rear end of the folding line 400, respectively. The opposite ends of the connecting piece 500 are connected to the fixed cover 310 and the movable cover 320, respectively, so that the fixed cover 310 and the movable cover 320 cannot rotate relative to each other, as shown in Figure 6 The cover body 300 is in a stable closed state at this time. The cover body 300 is stable in structure and the opening is downward. When the box body 200 and the cover body 300 are connected, the packaging box 100 is in a stable closed state. The connecting piece 500 can effectively prevent water vapor from entering the storage cavity 210 from the rotating structure of the fixed cover 310 and the movable cover 320, thereby preventing the articles in the storage cavity 210 from being damp.

[0051] In this way, the packaging box 100 can effectively protect the articles in the storage cavity 210, and the sealing effect of the packaging box 100 is good. When the packaging box 100 is opened for the first time, people need to break the connecting piece 500 at both ends of the folding line 400 by breaking the movable cover 320 upward, at this time, the movable cover 320 and the fixed cover 310 can be rotated along the folding line 400, and the packaging box 100 can be converted to an open state according to the use requirement or rotated to a closed state according to the storage requirement.

[0052] It can be understood that the two ends of each connecting piece 500 in the horizontal direction are connected to the fixed cover 310 and the movable cover 320, respectively. The upper end of the connecting piece 500 is connected to the folding line 400, and the lower end of the connecting piece 500 is horizontally opposite to the lower end of the fixed cover 310 and the movable cover 320. In this way, the connecting piece 500 can stably block the gap between the fixed cover 310 and the movable cover 320, preventing water vapor from entering the storage cavity 210. Moreover, the cover body 300 after production can be directly connected with the box body 200 through the upper and lower cover connection, so that the assembly of the packaging box 100 is more simple and fast.

[0053] It can be understood that the inner wall of the connecting piece 500 is inwardly recessed with a tear groove 510, and the connecting piece 500 and the tear groove 510 are corresponding inside and outside, as shown in Figure 6 and Figure 8As shown, the part of the connecting piece 500 with the easy-to-tear slot 510 is thinner than the fixed cover 310 and the movable cover 320. Therefore, when the packaging box 100 is opened for the first time and the movable cover 320 is pulled upward, the cover body 300 is easily broken along the easy-to-tear slot 510, so that the cover body 300 is changed from the fixed closed state to the rotatable open or closed state, and the fixed cover 310 and the movable cover 320 can be rotated along the folding line 400, thereby realizing the opening and closing of the packaging box 100.
