[0029] A first connecting part extending outwardly is installed on the cover body (31), and a second connecting part extending upwardly is installed on the connecting annular body (21). One of the first connecting part and the second connecting part is provided with a rotation axis (312), and the first connecting part and the second connecting part are rotatably connected around the axis line of the rotation axis (312) to implement a rotational connection between the core body box (2) and the box cover (3). In this embodiment, referring to FIG. 2, the first connecting part includes two protruding lugs (311) extending outwardly from the outer periphery of the cover body (31), and the rotation axis (312) is connected between the two protruding lugs (311); the second connecting part includes a hook-type lug (211) that is hooked onto the rotation axis (312) to allow the rotation axis (312) to rotate around its own axis line internally, and the hook-type lug (211) is U-shaped with an opening facing downward.

[0030] In this embodiment, the rotation shaft (312) and two protruding lugs (311) are installed integrally, and the rotation shaft (312) and the outer periphery of the cover body (31) are installed spaced apart from each other. An insertion opening (313) is formed between the rotation shaft and the outer periphery of the cover body to allow the outer part of the hanging lug (211) to be inserted in alignment. The outer periphery of the connecting annular body (21) is provided with an avoidance groove (212) extending along the vertical direction, and the hanging lug (211) is installed in the avoidance groove (212), and at least the lower outer periphery of the hanging lug (211) is aligned with the outer wall of the mounting groove (12). By installing it in this way, the rotating shaft (312) can be injection molded integrally with the box cover (3), and the box cover (3) can rotate around the axis line of the rotating shaft (312) to cover the upper part of the core body box (2).

[0031] The connecting annular body (21) includes a first annular body (213) and a second annular body (214) installed in a rounded shape on the outer circumferential side of the first annular body (213). An opening groove (215) is formed between the first annular body (213) and the second annular body (214), with the opening facing downward and forming an annular shape. The outer wall of the second annular body (214) is elastically in contact with the outer wall of the mounting groove (12). In some other embodiments, a sealing structure that fits together may be installed between the outer wall of the second annular body (214) and the outer wall of the mounting groove (12) to prevent external material from entering the mounting groove (12) through the gap between the outer wall of the second annular body (214) and the outer wall of the mounting groove (12) and contaminating the mounting groove (12).

[0032] The mounting annular body (22) is installed to fit on the outer circumferential side of the annular partition (13), and the first sealing structure (4) is installed in a single group or in a plurality of groups spaced apart along the vertical direction. Specifically, the first sealing structure (4) includes a projection (41) and a concave groove (42) that are aligned with each other and all form an annular shape, the projection (41) elastically contacts the concave groove (42), the projection (41) extends outwardly from the outer circumferential wall of the annular partition (13), and the concave groove (42) extends outwardly from the inner circumferential surface of the mounting annular body (22); or, the projection (41) extends inwardly from the inner circumferential surface of the mounting annular body (22), and the concave groove (42) extends inwardly from the outer circumferential wall of the annular partition (13). In some other embodiments, the first sealing structure (4) may include only a projection (41) that is installed on the outer wall of the annular partition (13) and extends outwardly, and when the mounting annular body (22) is inserted into the mounting groove (12), the projection (41) is in close contact with the inner surface of the mounting annular body (22), or the first sealing structure (4) may include only a projection (41) that is installed on the inner surface of the mounting annular body (22) and extends inwardly, and when the core body box (2) is inserted into the mounting groove (12), the projection (41) is in close contact with the outer wall of the annular partition (13).

[0033] In this embodiment, the first sealing structure (4) is installed in two groups, and the first sealing structures (4) of the two groups are spaced apart along the vertical direction. The first sealing structure (4) located on the upper side includes a projection (41) that protrudes inwardly from the inner circumference of the mounting annular body (22), and the first sealing structure (4) located on the lower side includes a projection (41) that protrudes outwardly from the outer circumference of the annular partition (13) and a concave groove (42) that is sunk outwardly from the inner circumference of the mounting annular body (22). When the mounting annular body (22) is inserted and installed in the mounting groove (12), the projection (41) on the upper side comes into contact with the outer circumference of the annular partition (13), and the projection (41) on the lower side comes into contact with the groove wall of the concave groove (42). Under the action of the first sealing structure (4) of the two groups, the core body box (2) and the box body (1) are not only fixed to each other, but also prevent the cosmetic product in the receiving cavity (11) from leaking into the mounting groove (12).

[0034] In this embodiment, the outer surface of the covering (32) forms a tapered surface in which the outer diameter gradually decreases from top to bottom, and the second sealing structure includes an annular projection (321) installed on the outer surface of the covering (32) and extending outwardly along the radial direction, and the inner surface of the inner annular body (24) is a cylindrical surface, and during the process of the box cover (3) being covered downward, the outer surface of the covering (32) drives the inner annular body (24) to be deflected toward one side of the annular groove (25), and after the box cover (3) is covered on the upper part of the core body box (2), the annular projection (321) comes into contact with the inner surface of the inner annular body (24) to achieve a seal between the box cover (3) and the core body box (2). At the same time, the inner annular body (24) tends to move inward and reset due to its own elastic force, which also improves the sealing effect by causing the annular projection (321) and the inner annular body (24) to come into closer contact. Under the action of the second sealing structure, the problem of the cosmetic in the receiving cavity (11) drying out and deteriorating can be prevented, and the cosmetic can also be prevented from leaking out of the receiving cavity (11).

[0035] Referring to FIGS. 1 to 3, the cosmetic packaging box further includes an outer cover (5), the outer cover (5) is movably connected to the box body (1), and when the outer cover (5) and the box body (1) are aligned with each other, they can be closed to form a box cavity (6) capable of accommodating the box cover (3) and the core body box (2). In this embodiment, the outer cover (5) is rotatably connected to the box body (1) through a rotation axis (not shown) extended along the horizontal direction. Specifically, the outer cover (5) includes a main body part (51) and a third connecting part (52) extending downward from one end of the main body part (51), and a first through hole (521) is provided in the lower part of the third connecting part (52) and extends along the horizontal direction. A vertical groove (14) is provided in the outer periphery of the box body (1) and extends along the vertical direction. Two groups of second through holes (141) are installed in the outer walls of the box body (1) on both sides of the vertical groove (14) and extend horizontally along the same direction. The third connecting part (52) is inserted and installed in the vertical groove (14), and the rotation shaft is installed through the first through hole (521), while both ends of the rotation shaft are installed through the second through hole (141).

[0036] In another embodiment, the outer cover (5) and the box body (1) may be connected in a manner similar to the connection between the box cover (3) and the core box (2), and accordingly, the rotation axis may be directly formed integrally with the outer cover (5) or the box body (1), so there is no need to additionally install a rotation axis.

[0037] In this embodiment, a lens (7) is further installed within the main body (51) of the outer cover (5).

[0038] Referring to FIG. 4, the rotational connection position between the outer cover (5) and the box body (1) and the rotational connection position between the box cover (3) and the core body box (2) are installed so as to be spaced apart from each other in the circumferential direction, which not only facilitates the layout of each component within the packaging box, but also prevents interference when opening the box cover (3) while the outer cover (5) is open, and does not block the lens (7) inside the outer cover (5), making it easy to apply makeup and use.

[0039] The cosmetic packaging box of the present embodiment is suitable for filling cosmetics such as air cushion powder, and the cosmetic can be filled and the assembly of the cosmetic packaging box of the present embodiment completed as follows:

[0040] First, the cosmetic is filled into the receiving cavity (11) of the box body (1); then, the outer part of the hanging lug (211) is inserted into the insertion opening (313) and hung on the rotation axis (312) so that the box cover (3) and the core body box (2) are connected, and then the connected box cover (3) and the core body box (2) are installed on the box body (1) from top to bottom so that the mounting ring body (22) is inserted into the mounting groove (12) and the core body box (2) is fixed and assembled to the box body (1); then, the outer cover (5) and the box body (1) are connected through the rotation axis to complete the assembly.

[0041] In the cosmetic packaging box of the present embodiment, the outer cover (5), box cover (3), core body box (2), and box body (1) are manufactured from the same or similar material, and each component is integrally molded by a corresponding mold, and each component can be completed with only a first molding. When the packaging box is retrieved after the cosmetic is used up, the rotating shaft is removed and the lens (7) is removed from the outer cover (5), and the lens (7) and the rotating shaft are retrieved separately, and the box body (1), core body box (2), and box cover (3) can be retrieved directly without needing to be disassembled, making the retrieval process relatively simple. In some other embodiments, when the rotating shaft is integrally molded with the outer cover (5) or the box body (1), during the retrieval step, only the lens (7) needs to be removed and retrieved separately without needing to disassemble the rotating shaft, and the remaining structure of the packaging box can be retrieved directly without needing to be disassembled, thereby simplifying the disassembly process during retrieval.

[0042] In summary, the cosmetic packaging box of the present embodiment provides a box body (1), a core body box (2), and a box cover (3) that are each integrally molded and installed. By assembling and forming the packaging box through structural alignment between the respective components, on the one hand, the box body (1) and the core body box (2) are directly aligned to contain the cosmetic, thereby reducing the number of components of the packaging box and correspondingly reducing the number of molding dies, thus reducing manufacturing costs; on the other hand, the rotation axis (312) can be integrally molded with the cover body (31), so there is no need to install the rotation axis separately, thereby simplifying the assembly work of the packaging box. At the same time, the box body (1), the core body box (2), and the box cover (3) can be directly recovered without the need for disassembly, thereby simplifying the disassembly work during recovery.
