DETAILED DESCRIPTION

[0030] The technical solution of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments, so that the advantages and features of the present invention can be more easily understood by those skilled in the art.

[0031] Referring to a cosmetic packaging box shown in Figures 1 and 2, it includes: a box body 1, a core box 2 and a box cover 3, wherein the box body 1 has a accommodating cavity 11 with an upward mouth, and a mounting groove 12 arranged on the circumferential outside of the accommodating cavity 11, and an annular partition 13 is formed between the accommodating cavity 11 and the mounting groove 12; the core box 2 includes a connecting ring body 21 and a mounting ring body 22 connected in the up and down directions, the connecting ring body 21 and the mounting ring body 22 are both annular, the outer diameter of the connecting ring body 21 is larger than the outer diameter of the mounting ring body 22, a limit platform 23 protruding and extending radially inward is formed between the connecting ring body 21 and the mounting ring body 22, the limit platform 23 has an inner ring body 24 protruding and extending upward, the inner ring body 24 is located on the circumferential inner side of the connecting ring body 21, and an annular groove 25 is formed between the inner ring body 24 and the connecting ring body 21; the box cover 3 has a cover body 31, and a cover ring 32 protruding and extending downward from the cover body 31.

[0032] It should be noted that the ring shape here is not limited to the circular ring shape shown in Figures 1 to 6, but also includes a structure that is closed along the circumference and has a through hole in the middle, such as a ring with a square cross-section. In other words, the packaging box can be designed as a cylindrical box, a square box, or other shapes, which are not limited here.

[0033] The box body 1, the core box 2 and the box cover 3 are each an integral component formed in one piece, wherein the mounting ring body 22 is cooperatively inserted into the mounting groove 12 and fixed in the mounting groove 12, the limit platform 23 is located above the annular partition 13 and partially blocks the mouth of the accommodating cavity 11, and a first sealing structure 4 is provided between the inner circumference of the mounting ring body 22 and the outer circumference of the annular partition 13; one end of the cover body 31 is rotatably connected to the connecting ring body 21, and the cover ring 32 can be cooperatively inserted into the inner ring body 24, and a second sealing structure is provided between the outer circumference of the cover ring 32 and the inner circumference of the inner ring body 24.

[0034] In the cosmetic packaging container of this embodiment, the various parts are specifically arranged as follows:

[0035] The cover body 31 is provided with a first connecting portion that protrudes outward, and the connecting ring body 21 is provided with a second connecting portion that protrudes upward. One of the first connecting portion and the second connecting portion has a rotating shaft 312, and the first and second connecting portions are rotatably connected about the axis of the rotating shaft 312. Specifically, as shown in Figure 2, the first connecting portion includes two lugs 311 that protrude outward from the outer periphery of the cover body 31, and the rotating shaft 312 is connected between the two lugs 311. The second connecting portion includes a hanging ear 211 that can be hooked on the rotating shaft 312 and allows the rotating shaft 312 to rotate therein about its own axis. The hanging ear 211 is U-shaped with the opening facing downward.

[0036] In this embodiment, the rotating shaft 312 is integrally provided with the two lugs 311. The rotating shaft 312 is spaced apart from the outer periphery of the lid body 31, and an insertion opening 313 is formed therebetween into which the outer periphery of the lugs 211 can be inserted. The outer periphery of the connecting ring body 21 has a vertically extending escape groove 212. The lugs 211 are disposed within the escape groove 212, and the outer periphery of the lugs 211 cooperatively abut against the outer peripheral wall of the mounting groove 12. This arrangement of the rotating shaft 312 allows for integral injection molding with the lid 3, allowing the lid 3 to rotate about the axis of the rotating shaft 312 and close over the core box 2.

[0037] The connecting ring body 21 includes a first ring body 213 and a second ring body 214 disposed circumferentially outward from the first ring body 213. A downwardly-opening, annular groove 215 is formed between the first ring body 213 and the second ring body 214. The outer peripheral wall of the second ring body 214 elastically abuts against the outer peripheral wall of the mounting groove 12. In some embodiments, a sealing structure may be provided between the outer peripheral wall of the second ring body 214 and the outer peripheral wall of the mounting groove 12 to prevent external substances from entering the mounting groove 12 through the gap between the two and causing contamination.

[0038] The mounting ring 22 fits snugly around the circumferential outer side of the annular diaphragm 13, and the first sealing structure 4 comprises one or multiple groups of first sealing structures spaced apart in the vertical direction. Specifically, the first sealing structure 4 includes a mating annular protrusion 41 and a groove 42, each of which is annular. The protrusion 41 elastically abuts against the groove 42. The protrusion 41 protrudes outward from the outer circumferential wall of the annular diaphragm 13, while the groove 42 extends outward from the inner circumferential surface of the mounting ring 22. Alternatively, the protrusion 41 protrudes inward from the inner circumferential surface of the mounting ring 22, while the groove 42 extends inward from the outer circumferential wall of the annular diaphragm 13. In some other embodiments, the first sealing structure 4 may also only include a protrusion 41 provided on the outer peripheral wall of the annular partition 13 and protruding outward. When the core box 2 is inserted into the mounting groove 12, the protrusion 41 is tightly against the inner peripheral surface of the mounting ring body 22. Alternatively, the first sealing structure 4 may also only include a protrusion 41 provided on the inner peripheral surface of the mounting ring body 22 and protruding inward. When the core box 2 is inserted into the mounting groove 12, the protrusion 41 is tightly against the outer peripheral wall of the annular partition 13.

[0039] In this embodiment, two sets of first sealing structures 4 are provided, spaced apart in the vertical direction. The upper first sealing structure 4 comprises a protrusion 41a extending inwardly from the inner circumferential surface of the mounting ring 22. The lower first sealing structure 4 comprises a protrusion 41b extending outwardly from the outer circumferential wall of the annular partition 13 and a groove 42 extending outwardly from the inner circumferential surface of the mounting ring 22. When the mounting ring 22 is inserted into the mounting groove 12, the protrusion 41a tightly abuts the outer circumferential wall of the annular partition 13, while the protrusion 41b abuts the groove 42. These two sets of first sealing structures 4 prevent cosmetics in the accommodating chamber 11 from leaking into the mounting groove 12.

[0040] In this embodiment, the outer peripheral surface of the cover ring 32 is a conical surface with an outer diameter that gradually decreases from top to bottom. The second sealing structure includes an annular protrusion 321 provided on the outer peripheral surface of the cover ring 32 and extending radially outward. The inner peripheral surface of the inner ring body 24 is a cylindrical surface. When the box cover 3 is closed downward, the outer peripheral surface of the cover ring 32 will drive the inner ring body 24 to deflect toward the side of the annular groove 25. After the box cover 3 is closed on the top of the core box 2, the annular protrusion 321 and the inner peripheral surface of the inner ring body 24 abut together, thereby achieving a seal. At the same time, under the action of the elastic force of the inner ring body 24 returning to its original shape, the abutment between the two is made tighter, thereby improving the sealing effect. Under the action of the second sealing structure, the problem of cosmetics in the accommodating chamber 11 drying and deteriorating can be avoided, and the cosmetics can also be prevented from leaking out of the accommodating chamber 11.

[0041] Referring to Figures 1 to 3, the cosmetic packaging box also includes an outer cover 5, which is movably connected to the box body 1. When the outer cover 5 and the box body 1 cooperate with each other, they can form a closed box cavity 6 that can accommodate the box cover 3. Referring to Figure 2, in this embodiment, the outer cover 5 is rotatably connected to the box body 1 via a rotating shaft (not shown) extending in the horizontal direction. Specifically, the outer cover 5 includes a main body 51 and a third connecting portion 52 extending downward from one end of the main body 51. The lower portion of the third connecting portion 52 has a first through hole 521 extending horizontally. The outer periphery of the box body 1 has a vertical slot 14 extending in the vertical direction. In the horizontal direction, two groups of second through holes 141 extending horizontally in the same direction are provided on the outer wall of the box body 1 on both sides of the vertical slot 14. The third connecting portion 52 is inserted into the vertical slot 14, and the rotating shaft is inserted into the first through hole 521 while the two ends of the rotating shaft are inserted into the second through holes 141.

[0042] In other embodiments, the outer cover 5 and the box body 1 can also be connected in a manner similar to the connection between the box cover 3 and the core box 2, so that the rotating shaft can be directly integrally formed with the outer cover 5 or the box body 1, thereby eliminating the need for an additional rotating shaft.

[0043] In this embodiment, a lens 7 is further provided in the main body 51 of the outer cover 5 for the convenience of the user.

[0044] As shown in Figure 4, the rotational connection positions between the outer cover 5 and the box body 1 and the rotational connection positions between the box cover 3 and the core box 2 are arranged at intervals from each other in the circumferential direction. This not only facilitates the layout of the various components in the packaging box, but also ensures that when the outer cover 5 is opened, there will be no interference when the box cover 3 is opened again, and the lens 7 on the inner side of the outer cover 5 will not be blocked, which is convenient for makeup use.

[0045] The cosmetic container of this embodiment is suitable for filling cosmetics such as air cushion powder. The specific process of filling the cosmetics and assembling the cosmetic packaging box at the same time is as follows:

[0046] First, fill the accommodating cavity 11 of the box body 1 with cosmetics; insert the outer portion of the ear 211 into the insertion port 313 and hook it on the rotating shaft 312, so that the box cover 3 and the core box 2 are connected together; then, install the connected box cover 3 and the core box 2 on the box body 1 from top to bottom, so that the mounting ring 22 is inserted into the mounting groove 12; then, connect the outer cover 5 and the box body 1 together through the rotating shaft to complete the assembly.

[0047] In the cosmetic packaging box of this embodiment, the outer cover 5, the box lid 3, the core box 2, and the box body 1 are made of the same or similar materials, and each component is integrally formed by corresponding molds. After the cosmetics are used up, when the packaging box is recycled, it is only necessary to remove the rotating shaft and remove the lens 7 from the outer cover 5. The lens 7 and the rotating shaft can be recycled separately, while the box body 1, the core box 2, and the box lid 3 do not need to be disassembled and can be directly recycled, which simplifies the recycling operation. In other embodiments, when the rotating shaft is integrally formed on the outer cover 5 or the box body 1, when recycling, it is not necessary to disassemble the rotating shaft. Instead, it is necessary to remove the lens 7 and recycle it separately. The rest of the packaging box does not need to be disassembled and can be directly recycled, which simplifies the disassembly work during recycling.

[0048] In summary, the cosmetic packaging box of this embodiment provides a box body 1, a core box 2 and a box cover 3, which are each integrally formed. The packaging box is assembled through structural coordination between the components. On the one hand, the number of components of the packaging box is reduced, the number of molding molds is reduced, and the manufacturing cost is reduced. On the other hand, in this embodiment, the rotating shaft 312 can be integrally formed with the cover body 31, and there is no need to set up an additional rotating shaft, which simplifies the assembly operation of the packaging box. At the same time, the box body 1, the core box 2 and the box cover 3 do not need to be disassembled and can be directly recycled, which simplifies the disassembly work during recycling.

[0049] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the essence of the present invention are intended to be included within the scope of protection of the present invention.
