[0037] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0038] Example 1: Figure 1-6 As shown, a replaceable liner assembly 100 includes an liner 110, and the liner 110 includes an upper open end 111 with a hollow and a lower closed end 112, and the upper open end 111 extends radially outward to form a joint 113. When the liner 110 is placed on a horizontal support surface, an angle exists between the central axis of the liner 110 and the normal of the horizontal support surface. The horizontal plane is a plane formed by relatively completely still water, and the horizontal support surface refers to a support surface parallel to the horizontal plane. When the liner 110 is placed on the horizontal support surface, the liner 110 tilts to one side, and when the liner 110 and the horizontal support surface are relatively still, an angle exists between the central axis of the liner 110 and the normal of the horizontal support surface.
[0039] like Figure 1 As shown, the inner liner 110 is a cylindrical structure with an open upper end, a closed lower end, and a hollow interior. The inner liner 110 is hollow to form a receiving groove for storing cosmetic materials or skin care materials. The above-mentioned materials can be pastes or powders. The upper open end 111 forms a circle of closed joints 113 along the circumferential direction, and there is a certain gap between the joints 113 and the inner liner 110. Optionally, as shown in FIG. 8 As shown, the upper open end 111 first extends radially outward and then extends axially downward to form a joint portion 113 with a longitudinal cross section similar to an "L" shape. Figure 7 As shown, the inner liner assembly 100 further includes a pull tab 120 and a gasket 140 . The pull tab 120 is covered on the inner liner 110 . The gasket 140 is provided between the outer cover 210 and the inner liner 110 . The gasket 140 is used to seal the inner liner 110 .
[0040] Since the inner liner 110 in the present application is placed on a horizontal support surface, there is an angle between the central axis of the inner liner 110 and the normal of the support surface, that is, the inner liner 110 cannot stand on the upper horizontal support surface so that the open end 111 is horizontally upward, so the inner liner 110 must be placed in the outer bottle 220 before it can be used. The inner liner 110 is placed in the outer bottle 220 for use, thereby preventing the inner liner 110 from being forgotten by the user, thereby causing the material in the inner liner 110 to be contaminated or even the inner liner assembly 100 to be lost.
[0041] Optionally, the shape of the lower closed end 112 includes a hemispherical shape, a conical shape or a spherical sector shape. Designing the lower closed end 112 of the inner liner 110 to be the above shape can ensure that when the inner liner 110 is placed alone on a desktop, the inner liner 110 cannot stand up. Therefore, the inner liner 110 must be placed in the outer bottle 220 before use. Figure 1 The lower closed end 112 of the inner liner 110 shown in FIG. 1 is hemispherical.
[0042] Optionally, the lower closed end 112 is provided with a tip, and the tip is located at the axial position of the inner container 110. The center position of the lower closed end 112 of the inner container 110 is designed to be a tip, and the contact area between the lower closed end 112 and the support surface is small. When the inner container 110 is placed on a desktop, the inner container 110 is tilted and the open end 111 cannot be kept horizontally upward.
[0043] like Figure 2-6As shown, the liner assembly 100 further includes a replacement cover 130, which covers the liner 110. The liner 110 is sealed by a sealing foil 150 to improve the sealing effect of the liner 110. A gasket 140 is provided between the replacement cover 130 and the liner 110. The replacement cover 130 and the liner 110 form a replacement assembly, and the liner 110 is loaded into the outer shell assembly 200 to form a regular assembly. When shipped, the regular assembly and the replacement assembly are shipped at the same time. When the material in the liner 110 of the regular assembly is used up, the liner 110 is removed from the outer shell assembly 200, and then the replacement cover 130 in the replacement assembly is screwed off, and the liner 110 in the replacement assembly is loaded into the outer shell assembly 200.
[0044] like Figure 3 and Figure 6 As shown, the inner side wall of the replacement cover 130 forms a sealing rib 131 radially inwardly, and the sealing rib 131 is interference-fitted with the joint 113. Optionally, the inner side wall of the replacement cover 130 is provided with a plurality of evenly arranged sealing ribs 131, and the sealing rib 131 is interference-fitted with the outer side wall of the joint 113 to seal the liner 110, thereby improving the sealing effect of the liner 110 during storage.
[0045] Example 2: Figure 7-13 As shown, a cosmetic container includes an inner liner component 100 and an outer shell component 200, the outer shell component 200 includes an outer bottle 220, the inner liner 110 is detachably installed in the outer bottle 220, the coupling portion 113 is buckled on the top of the outer bottle 220, and the top of the outer bottle 220 is interference fit with the inner liner 110.
[0046] The outer bottle 220 is a cylindrical structure with openings at both ends and a hollow interior, or the outer bottle 220 is a cylindrical structure with an opening at the upper end and a closed lower end and a hollow interior. The hollow interior of the outer bottle 220 forms a receiving groove for placing the inner liner 110. Figure 7 As shown, in the embodiment provided by the present application, the outer bottle 220 is a cylindrical structure with an open upper end, a closed lower end, and a hollow interior. When the inner liner 110 is installed in the outer bottle 220, the top of the outer bottle 220 is inserted into the joint 113, and the top of the outer bottle 220 and the inner liner 110 are interference fit so that the two are tightly combined. The inner liner 110 includes an inner liner body and a joint 113, and the top of the outer bottle 220 and the inner liner 110 are interference fit, which means: the top of the outer bottle 220 and the inner liner body are interference fit; or, the top of the outer bottle and the joint 113 are interference fit; or, the top of the outer bottle 220 and the inner liner body and the joint 113 are both interference fit. When the material in the inner liner 110 is used up, the inner liner 110 is pushed upward from the hollow bottom of the outer bottle 220 or directly pulled out from the upper end of the outer bottle 220, so that the inner liner 110 moves upward to separate from the outer bottle 220, and then a new inner liner 110 is installed. The operation is very convenient.
[0047] In the present application, the inner liner 110 is buckled on the top of the outer bottle 220 through the joint 113, and then the inner liner 110 and the top of the outer bottle 220 are interference fit to make the two tightly combined, so the installation and disassembly of the inner liner 110 is very convenient, and the structure of the inner liner 110 and the outer bottle 220 is simple, the manufacturing cost is low, and it is easy to industrialize production; in the present application, the inner liner 110 can be replaced, so all parts except the inner liner 110 can be reused, reducing resource waste and meeting environmental protection requirements.
[0048] like Figure 7 and Figure 8 As shown, the top of the outer bottle 220 is provided with an insert 221, which extends along the axial direction of the outer bottle 220 in a direction away from the bottom of the outer bottle 220, and the insert 221 is inserted into the joint 113, and the insert 221 and the joint 113 are interference fit. The thickness of the insert 221 is less than the thickness of the top of the outer bottle 220, and the insert 221 and the joint 113 are interference fit through the convex rib, so that the inner liner 110 and the outer bottle 220 are fixedly installed, with a simple structure and convenient installation. Optionally, the outer side wall of the insert 221 extends radially outward to form a convex rib; or, the inner side wall of the joint 113 extends radially inward to form a convex rib.
[0049] like Figure 7 , Figure 11-13 As shown, the housing assembly 200 further includes an outer cover 210, which covers the outer bottle 220. The inner wall of the outer cover 210 is provided with an elastic sheet 213, which abuts against the anti-rotation portion 223 of the outer bottle 220. When the outer cover 210 is screwed onto the outer bottle 220, the elastic sheet 213 abuts against the anti-rotation portion 223 to prevent the outer cover 210 from excessive rotation.
[0050] like Figure 7 and Figure 8 As shown, the outer cap 210 is provided with an inner ring 211, the inner side wall of the inner ring 211 is provided with an inner thread 212, the outer side wall of the outer bottle 220 is provided with an outer thread 222, and the outer cap 210 and the outer bottle 220 are screwed and fixed by the inner thread 212 and the outer thread 222. Figure 11-12As shown, the spring piece 213 is close to the end of the internal thread 212. The end of the external thread 222 extends axially downward on the side wall of the outer bottle 220 to form a stopper 223. The outer cover 210 is provided with an inner ring 211 and an outer ring 214, the outer ring 214 is located outside the inner ring 211, and there is a gap between the outer ring 214 and the inner ring 211, and the inner ring 211 is combined with the outer bottle 220, so that the thickness of the side wall of the outer cover 210 can be reduced and the weight of the cosmetic container as a whole can be reduced. The spring piece 213 is close to the end of the internal thread 212, that is, there is a gap between the spring piece 213 and the internal thread 212. When the outer cover 210 is tightened on the outer bottle 220, the spring piece 213 passes over the stopper 223, and the stopper 223 is engaged in the gap. This process will produce a click sound to remind the user that the rotation cannot continue, which not only prevents the outer cover 210 from rotating excessively, but also increases the interest of the cosmetic container.
[0051] Optionally, the spring sheet 213 protrudes radially inward from the inner ring 211, and at least a portion of the outer wall of the spring sheet 213 is connected to the inner ring 211. It may include that only a portion of the outer wall of the spring sheet is connected to the inner ring 211, or all the outer walls are connected to the side wall of the inner ring 211.
[0052] Alternatively, if Fig.11 and Fig.12 As shown, in Example 2, the outer wall of the spring piece 213 is fixedly connected to the inner wall of the inner ring 211; when the outer cover 210 and the outer bottle 220 are made of softer materials, the outer wall of the spring piece 213 is fixedly connected to the inner wall of the hollow groove through the connecting piece 215, which can meet the elasticity requirements of the spring piece 213 and is simple to manufacture.
[0053] Example 3: Fig.14 and Fig.15 As shown, the spring piece 213 is located in the hollow groove, the spring piece 213 protrudes radially inward from the inner ring 211, and at least a part of the outer wall of the spring piece 213 is disconnected from the inner wall of the inner ring 211. Optionally, in this embodiment, the spring piece 213 is a square structure, the spring piece 213 has an outer wall around, only a part of the outer wall is connected to the inner wall of the inner ring 211, and the rest of the outer wall of the spring piece 213 is disconnected from the inner wall of the inner ring 211. When the outer cover 210 and the outer bottle 220 are made of a harder material, a part of the spring piece 213 is disconnected from the inner ring 211, so that the spring piece 213 can be greatly deformed, thereby not affecting the screwing effect.
[0054] It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these modifications and improvements are all within the scope of protection of the present application. Therefore, the scope of protection of the patent of the present application shall be subject to the attached claims.
