The first folding surface 102 and the second folding surface 103 are respectively connected to two adjacent first side surfaces 101. The four groups of first side surfaces 101 are folded relative to the bottom surface to obtain a box-type structure. The setting of the folding surface is convenient for obtaining die-cut cardboard on the one hand, and can increase the structural stability of the box-type structure on the other hand. It should be noted that the bottom surface is set as a quadrilateral structure in this embodiment based on the preferred shape of the commonly used packaging box, and it is not a restrictive provision. The shape of the box-type structure can be adjusted accordingly according to design needs and market needs.

[0033] The first side surfaces 101 are all connected to the second side surfaces 104, wherein two parallel second side surfaces 104 are connected to the first connection parts for connecting to the bottom surface, and the other two parallel second side surfaces 104 are connected to the second connection parts for folding to form a fixing seat and for connecting to the bottom surface. In this embodiment, the width of the second side surface 104 is smaller than the width of the first side surface 101. The second side surface 104 is provided so that the wall of the packaging box is not a planar structure but a three-dimensional structure, so that the box-type structure has better shockproof performance and protection performance under the premise of using less materials.

[0034] Specifically, the first connection portion includes a third side surface 105 and a first overlap surface 106.

The first connecting surface 202, the second connecting surface 203, the third connecting surface 204 and the fourth connecting surface 205 are folded around to form a fourth cubic structure. The sixth connecting surface 207, the seventh connecting surface 208, the eighth connecting surface 209 and the ninth connecting surface 210 are folded around to form a fifth cubic structure. The fourth cubic structure and the fifth cubic structure are respectively attached to the seventh side surface 111. The first storage slot 201 is opened on the fourth connecting surface 205 and the sixth connecting surface 207. The fourth cubic structure and the fifth cubic structure are respectively fitted with the seventh side surface 111 of the fixing seat, and the first inner support 200 forms a U-shaped structure with empty grooves on both sides. The upper surfaces of the fourth cubic structure and the fifth cubic structure are arranged flush with the upper surface of the fixing seat, which increases the aesthetic appearance of the packaging box. In this embodiment, a row of circular holes 211 are arranged at the upper part of the fourth connecting surface 205, and a row of grooves 212 are arranged at the corresponding position of the sixth connecting surface 207 and the row of circular holes 211. The number of circular holes 211 and the number of grooves 212 are equal. The arrangement of the circular holes 211 and the grooves 212 in this embodiment is the first storage slot 201 arranged according to the shape of the liquid dispenser. The circular hole 211 is used to fix the tip of the liquid dispenser, and the groove 212 is used to fix the bottom of the liquid dispenser, which plays a good fixing role and shock-absorbing protection role. The shape of the first storage slot 201 in this embodiment is not limited to the shape of the combination of the circular hole 211 and the groove 212, and can be adjusted accordingly according to the shape of the placed cosmetics. Among them, the connection between the second connecting surface 203 and the third connecting surface 204, and the connection between the seventh connecting surface 208 and the eighth connecting surface 209 are both provided with a snap-in 213 that is snapped with the latch 113; the snap-in connection between the latch 113 and the snap-in 213 facilitates maintaining the shape of the first inner tray 200, and can effectively improve the shockproof and protective performance of the packaging box.
