[0034] As shown in Figures 1-13, a cosmetic container includes a cover 10 and a bottle body 20. The cover 10 is detachably attached to the bottle body 20. The cover 10 and the bottle body 20 are made of the same plastic material. The cover 10 includes a top cover 11 and a cylindrical portion 12 fixedly connected to the top cover 11. During molding, the top cover 11 protrudes in a direction away from the cylindrical portion 12, and / or a support member 14 is provided on the inner surface of the top cover 11 to support the top cover 11. The state of the top cover 11 during molding is defined as a first state, and the state of the top cover 11 after molding is defined as a second state. The curvature of the top cover 11 in the first state is less than or equal to the curvature of the top cover 11 in the second state. Optionally, the cover 10 and the bottle body 20 are made of the same soft plastic. In the prior art, a lid assembly typically includes an outer lid, an inner lid, and a gasket. This allows for a thinner outer lid, which prevents it from denting. However, the lid assembly has many components and is made of different materials, resulting in high processing costs, a complex assembly process, and inconvenient recycling. Therefore, a one-piece lid has emerged. In order to meet the strength requirements of the one-piece cover, the top cover 11 of the cover is relatively thick. In traditional processes, the top cover 11 is a flat structure throughout the entire molding process. Therefore, the cover 10 made of soft plastic will sag during the molding process due to the shrinkage of the plastic material, affecting the use and appearance of the container. In a possible embodiment, the mold for the injection molding of the cover 10 is designed to be an arc structure in this application. Therefore, when the cover 10 is molded in the mold, the top cover 11 is convex, and when the mold is opened to take out the cover 10, the top cover 11 is also convex; during the cooling process of the cover 10, the top cover 11 shrinks due to the shrinkage of the plastic material. After the cover 10 has cooled for a period of time, the cover 10 reaches a molding state, that is, the shape of the top cover 11 no longer changes. At this time, the top cover 11 is flat or slightly convex. Optionally, the cooling time ranges from 2 hours to 5 days. Since the top cover 11 shrinks during the shaping process, the curvature of the top cover 11 immediately after forming is smaller than the curvature after shaping, that is, the top cover 11 shrinks toward the interior of the cover body 10 .

[0035] In the present application, the top cover 11 is designed to be convex during molding, or a support member 14 is provided on the inner surface of the top cover 11, or the top cover 11 is designed to be convex during molding and a support member 14 is provided on the inner surface of the top cover 11. The convex top cover can offset the tendency of the top cover to sag, and the support member can provide a certain supporting force to the top cover, thereby effectively preventing the top cover from sag, extending the service life of the container, and reducing resource waste.

[0036] Example 1: As shown in Figures 1-5, the top cover 11 during molding is convex in the direction away from the bottle body 20, that is, the top cover 11 has a convex arc surface, but the inner surface of the top cover 11 is not provided with a support member 14. In this embodiment, the curvature of the top cover 11 in the first state is smaller than the curvature of the top cover 11 in the second state. In this embodiment, the arc surface structure of the top cover 11 is used to prevent the cover body from sinking. The structure of the cover body in this embodiment is simple.

[0037] The inner surface of the top cap 11 extends axially toward the bottle body 20 to form a seal 13, which is airtightly attached to the inner sidewall of the bottle body 20. The seal 13 is integrally formed with the lid body 10 and seals the lid body 10 and the bottle body 20 with the seal 13, eliminating the need for a separate gasket structure. This reduces the number of components in the cosmetic container, lowers the manufacturing cost, and improves the sealing performance of the container.

[0038] In one possible embodiment, as shown in Figures 1 and 3, the seal 13 is a thin sheet-like structure, with a ring of seal 13 formed circumferentially on the inner surface of the top cover 11 inside the cylindrical portion 12. An annular seal 13 is provided on the inner surface of the top cover 11 near the cylindrical portion 12. When the lid 10 is placed on the bottle body 20, the outer wall of the seal 13 is airtightly attached to the inner wall of the bottle body 20, thereby sealing the lid 10 and the bottle body 20. Optionally, the thickness of the seal 13 is less than the thickness of the bottle body 20. In one possible embodiment, the seal 13 is a hollow annular structure.

[0039] The opening 21 of the bottle body 20 is provided with a first chamfer 23, and / or the lower end of the seal 13 is provided with a second chamfer 16. The upper end of the seal 13 is integrally formed with the top cover 11. In one possible embodiment, the opening 21 of the bottle body 20 is provided with the first chamfer 23; in another possible embodiment, the lower end of the seal 13 is provided with the second chamfer 16; in yet another possible embodiment, as shown in FIG5 , the opening 21 of the bottle body 20 is provided with the first chamfer 23, and the lower end of the seal 13 is provided with the second chamfer 16. In this application, the design of the first chamfer 23 and / or the second chamfer 16 facilitates the cap 10 to be fitted over the bottle body 20.

[0040] As shown in Figure 5, the lower end of the seal 13 is bent toward the axis of the lid 10. This makes it easier for the lid 10 to be screwed into the bottle 20. At the same time, since the lower end of the seal 13 is curved, it will not rub against the inner wall of the bottle 20 to produce abnormal noise, thereby improving the user's comfort.

[0041] The lid 10 and bottle body 20 are integrally molded parts, and the plastic material includes polypropylene, polycarbonate, polyethylene terephthalate-1,4-cyclohexanedimethanol, or high-density polyethylene. Optionally, both the lid and bottle body are made of polypropylene (PP) to facilitate sorting and recycling of the containers. The lid 10 and bottle body 20 are connected by hinged, screwed, snap-fit, or magnetic connections. Optionally, the lid 10 and bottle body 20 are detachably connected by screwing.

[0042] As shown in Figures 3-4, the cylindrical portion 12 is a hollow cylinder with open ends at the upper and lower ends. The top cover 11 is fixedly sealed to the upper open end of the cylindrical portion 12. The upper end of the bottle body 20 is provided with an opening 21. The cylindrical portion 12 and the opening 21 are detachably connected.

[0043] In a first possible embodiment, as shown in Figures 3 and 4, the inner wall of the cylindrical portion 12 is provided with an internal thread 15, and the outer wall of the opening portion 21 is provided with an external thread 22, and the cylindrical portion 12 and the opening portion 21 are screwed and fixed by the internal thread 15 and the external thread 22.

[0044] In a second possible embodiment, the inner wall of the cylindrical portion 12 is provided with a first rib, and the outer wall of the opening portion 21 is provided with a second rib. The cylindrical portion 12 and the opening portion 21 are fixed together by the first and second ribs.

[0045] In a third possible embodiment, the inner wall of the cylindrical portion 12 is provided with a clamping rib, and the outer wall of the opening portion 21 is provided with a clamping groove, and the cylindrical portion 12 and the opening portion 21 are fixed by the clamping rib and the clamping groove.

[0046] In a fourth possible embodiment, a slot is provided on the inner wall of the cylindrical portion 12 and a rib is provided on the outer wall of the opening portion 21 . The cylindrical portion 12 and the opening portion 21 are fixed by the rib and the slot.

[0047] The cosmetic container in the present application includes a cover body 10 and a bottle body 20. Both the cover body and the bottle body are made of plastic material, which is convenient for recycling and reuse of the product. The support and sealing parts on the cover body are integrally formed with the cover body, so the sealing effect is good, the number of parts is small, the production cost is low and the assembly is easy.

[0048] Example 2: As shown in Figures 6-9, the top cover 11 is convex in the direction away from the bottle body 20 during molding, and the inner surface of the top cover 11 is also provided with a support member 14. In this embodiment, the curved surface structure of the top cover 11 and the support member 14 on the inner surface of the top cover 11 are used to prevent the cover body from sinking. In this embodiment, the curvature of the top cover 11 in the first state is smaller than the curvature of the top cover 11 in the second state. Compared with Example 1, the structure of the cover body in this embodiment is more stable.

[0049] The inner surface of the top cover 11 is provided with N strip-shaped support members 14 along the radial and / or circumferential directions, where N ≥ 2 and is an integer. That is, the support members 14 are strip-shaped. In one possible embodiment, the inner surface of the top cover 11 is provided with support members 14 along the radial direction. In another possible embodiment, the inner surface of the top cover 11 is provided with multiple circles of support members 14 along the circumferential direction, with all support members 14 arranged concentrically with the top cover 11. In yet another possible embodiment, the inner surface of the top cover 11 is provided with support members 14 along both the radial and circumferential directions, with the support members arranged in a mesh-like manner. This improves the strength of the top cover 11 and effectively prevents the top cover 11 from sagging.

[0050] As shown in Figure 8 , the support members 14 are optionally arranged along the radial direction of the inner surface of the top cover 11, with N support members 14 arranged radially around the center of the top cover 11, where 4 ≤ N ≤ 20. Optionally, the angles between two adjacent support members 14 are equal. This support member structure not only supports the top cover 11 but also facilitates the molding and demolding of the cover.

[0051] Example 3: As shown in Figures 10-13, the top cover 11 is flat during molding, and the inner surface of the top cover 11 is provided with a support member 14. In this embodiment, the support member 14 on the inner surface of the top cover 11 is used to prevent the cover body from sinking. In this embodiment, the curvature of the top cover 11 in the first state is equal to the curvature of the top cover 11 in the second state. Compared with Example 1, the structure of the cover body in this embodiment is more stable; compared with Example 2, the structure of the cover body in this embodiment is simpler.

[0052] It should be noted that those skilled in the art may make a number of modifications and improvements without departing from the concept of this application, and these modifications and improvements are all within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be based on the appended claims.
