[0041] Figures 1 to 14 The drawings are drawn in true proportion, and in order to maintain the brevity of the specification, the proportions and positions of the elements are not listed one by one, but the proportions and positions of the elements should be considered as part of the content of the specification.

[0042] Referring to Figures 1 to 14 The cosmetic packaging box shown in FIG. 1 comprises a base 1, an outer cover 2, a disc body 3 and an inner cover 4. The base 1 has an inner cavity with an upward opening and a closed bottom. The base 1 has an annular partition plate 13, which divides the inner cavity of the base 1 into a containing cavity 11 and a mounting cavity 12 arranged circumferentially outside the containing cavity 11. The containing cavity 11 is used to contain cosmetics. The outer cover 2 is movably connected to the base 1, and the outer cover 2 and the base 1 can cooperate with each other to form a receiving cavity, and the disc body 3 and the inner cover 4 can be accommodated in the receiving cavity.

[0043] The disc body 3 comprises a mounting frame portion 32 and a barrier portion 31 in the shape of a ring above the mounting frame portion 32, the mounting frame portion 32 is fittedly mounted in the mounting cavity 12, the barrier portion 31 is arranged above the annular partition plate 13, and the accommodating cavity 11 is exposed upward from the through hole of the barrier portion 31 for a user to take cosmetics in the accommodating cavity 11; the inner cover 4 is movably connected with the disc body 3 to be arranged open or closed relative to the disc body 3, the inner cover 4 comprises a cover body 41 and a sealing member 42 integrally arranged on the cover body 41, when the inner cover 4 is closed relative to the disc body 3, the sealing member 42 is in sealing contact with the barrier portion 31 in the up-down direction, realizing the sealing between the inner cover 4 and the disc body 3, thereby forming a seal on the circumferential outside of the accommodating cavity 11 to avoid leakage of the cosmetics.

[0044] Thus, the cosmetic packaging box only comprises the base 1, the outer cover 2, the disc body 3 and the inner cover 4, each component can be integrally injection molded by injection molding, and then the cosmetic packaging box is formed by assembling. When assembling, the outer cover 2, the disc body 3 and the inner cover 4 can be assembled together to form a whole assembly, and then the whole assembly is assembled and connected with the base 1 after the accommodating cavity 11 is filled with cosmetics, so that the assembly is more convenient.

[0045] Referring to the drawings, in the cosmetic packaging container of the embodiment, the upper surface of the barrier portion 31 is a plane, when the inner cover 4 is closed relative to the disc body 3, the sealing member 42 is deformed and in sealing connection with the upper surface of the barrier portion 31 in the up-down direction. Specifically, the sealing member 42 has a base portion 421 and a sealing portion 422 extending downward from the base portion 421, the base portion 421 is integrally arranged on the cover body 41, and the sealing portion 422 is in the shape of a ring, when the inner cover 4 is closed relative to the disc body 3, the sealing portion 422 is located on the circumferential outside of the through hole of the barrier portion 31, that is, a seal is formed on the circumferential outside of the accommodating cavity 11.

[0046] The sealing member 42 is made of a flexible and deformable material, such as TPE material, and the cover body 41 is made of a hard material, such as PP or PE material. The sealing member 42 is integrally injection molded on the cover body 41, and a two-shot molding process is used to form the integral inner cover 4 during production, so that the sealing member 42 can be stably and reliably attached to the cover body 41 without falling off. In the embodiment, the base portion 421 of the sealing member 42 is also in the shape of a ring and is embedded in the cover body 41 during molding, and the sealing portion 422 is arranged at a distance from the inner and outer circumferential edges of the base portion 421, which is more conducive to molding.

[0047] The sealing part 422 specifically comprises an annular root 42a, and an inner annular rib 42b and an outer annular rib 42c extending downward from the annular root 42a. The annular root 42a is connected to the base part 421. The outer annular rib 42c is annularly arranged on the outer side of the inner annular rib 42b in a radial direction. The annular root 42a, the inner annular rib 42b and the outer annular rib 42c form a U-shaped groove 42d with an opening downward.

[0048] When the sealing part 42 is not pressed in the up-down direction, the inner side wall of the inner annular rib 42b is arched inward in the radial direction, and the outer side wall of the outer annular rib 42c is arched outward in the radial direction. When the inner cover 4 is closed relative to the disc body 3, the lower part of the inner annular rib 42b and the lower part of the outer annular rib 42c move toward the U-shaped groove 42d, so that the inner annular rib 42b and the outer annular rib 42c are deformed and connected to the upper surface of the blocking part 31. The U-shaped groove 42d provides space for the deformation of the inner annular rib 42b and the outer annular rib 42c. During the pressing process, the inner annular rib 42b and the outer annular rib 42c can have a larger contact area with the disc body 3, thereby forming a stable and reliable seal between the inner cover 4 and the disc body 3.

[0049] Referring to the drawings, in the embodiment, the disc body 3 further comprises an annular connecting frame part 33, which is arranged on the outer side of the blocking part 31 and extends upward from the blocking part 31.

Specifically, the connecting frame part 33 has a hinge part 36, and the inner cover 4 has a connecting part 414 connected to the hinge part 36 through a rotating shaft, so that the inner cover 4 can be opened or closed relative to the disc body 3. Here, the hinge part 36 is two lugs protruding upward from the upper surface of the connecting frame part 33 and arranged in a spaced manner. The connecting part 414 is a protruding part arranged on one end of the disc body 3 and located between the two lugs and connected to the two lugs through a rotating shaft.

[0050] The inner cover 4 has a cover part 411 inserted into the connecting frame part 33 in a fitting manner. A clamping convex part and a clamping concave part are arranged between the outer side of the cover part 411 and the inner side of the connecting frame part 33 in a matching manner. When the cover part 411 is inserted into the connecting frame part 33 in a fitting manner, the clamping convex part and the clamping concave part are clamped to each other, so that the inner cover 4 and the disc body 3 are clamped and fixed to each other. Here, the clamping convex part is a clamping rib 412 arranged on the outer side of the cover part 411. The clamping concave part is a clamping groove 35 arranged on the inner side of the connecting frame part 33. The clamping rib 412 and the clamping groove 35 have a plurality of sets of corresponding matching parts.

[0051] In the embodiment, the disc body 3 and the inner cover 4 are both square, and the clamping protrusions 412 and the clamping grooves 35 are correspondingly arranged on the four edge portions of the cover joint portion 411 and the connecting frame portion 33, so that the disc body 3 and the inner cover 4 can be fixed in the circumferential direction. When the inner cover 4 is downwardly covered on the disc body 3, the force applied to the sealing member 42 in the circumferential direction is balanced, the sealing force between the sealing member 42 and the disc body 3 is distributed more evenly in the circumferential direction, and the sealing effect is better.

[0052] The mounting frame portion 32 is fitted on the outer side of the annular partition plate 13, and a plurality of sealing structures are arranged between the inner side of the mounting frame portion 32 and the outer side of the annular partition plate 13. Here, the sealing structure includes the annular protrusions 131 arranged on the outer side of the annular partition plate 13 and the annular recesses 321 arranged on the inner side of the mounting frame portion 32. The annular protrusions 131 and the annular recesses 321 have a plurality of groups arranged in the vertical direction and spaced from each other, so that the inner side of the mounting frame portion 32 and the outer side of the annular partition plate 13 are clamped and sealed in the circumferential direction.

[0053] The mounting cavity 12 also has a positioning structure for positioning the disc body 3. Specifically, the positioning structure includes the positioning protrusions 14 arranged in the mounting cavity 12 and extending in the vertical direction, and the positioning grooves 34 arranged on the outer side of the connecting frame portion 33 and extending in the vertical direction and capable of being fitted and inserted by the positioning protrusions 14. The positioning protrusions 14 and the positioning grooves 34 have two groups arranged at intervals. Here, the positioning protrusions 14 extend inward from the outer side of the mounting cavity 12, and the width of the positioning protrusions 14 is less than the width of the mounting cavity 12. The positioning grooves 34 are located at the lower portion of the connecting frame portion 33 and are at least downwardly open. When the disc body 3 is mounted on the base 1, the two groups of positioning protrusions 14 and the positioning grooves 34 are correspondingly arranged, and then the disc body 3 is pressed downward, so that the mounting frame portion 32 is fitted on the outer side of the annular partition plate 13, and the disc body 3 is fixed on the base 1 and sealed in the circumferential direction.

[0054] In some embodiments, the cosmetic packaging box inner container further includes a screen (not shown in the figure) fixed to the blocking portion 31 and arranged above the containing cavity 11. The user can dip the cosmetic in the containing cavity 11 by applying force to the screen through the sponge pad.

[0055] It needs to be explained that the "annular" mentioned in the application refers to the corresponding components in the circumferential direction, which can be circular or square, or other shapes, and should not be understood as a limitation on its shape. In the embodiment, the square is specifically used, the height of the base 1 and the outer cover 2 is similar, the upper surface of the connecting frame part 33 and the upper surface of the base 1 are flush with each other after the disc body 3 and the base 1 are assembled; the disc body 3 and the inner cover 4 are rotatably connected at one side, the inner cover 4 has an opening protrusion 415 on the opposite side, which is used for the user to operate to open the inner cover 4; the top of the inner cover 4 is provided with a downward recessed accommodating groove 413 for placing a sponge to facilitate the use of cosmetics;
