[0043] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the embodiments of the present application. Obviously, the embodiments described in the present application are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
[0044] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the following drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the objects used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0045] 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.
[0046] Example 1: Figure 1-10 As shown, an inner liner assembly includes an inner cover 10, an inner ring 20 and an inner plate 30, the inner ring 20 is installed on the inner plate 30, the inner cover 10 is rotatably connected to the inner plate 30, and the inner cover 10 can cover the inner plate 30, the inner ring 20 includes a ring body 21 and a first seal 23 and a second seal 24 fixed to the ring body 21, the inner cover 10 and the inner ring 20 are sealed by the first seal 23, and the inner ring 20 and the inner plate 30 are sealed by the second seal 24.
[0047] Among them, the inner cover 10 is used to place the puff, and the inner plate 30 is used to place cosmetic materials such as air cushions, creams or powder blocks. Among them, the powder block materials are such as highlights, shadows, lip glazes, etc. The inner ring 20 is installed between the inner cover 10 and the inner plate 30, and the inner ring 20 is used to seal the inner plate 30, that is, the first seal 23 on the inner ring 20 is used to seal the gap between the inner cover 10 and the inner ring 20, and the second seal 24 on the inner ring 20 is used to seal the gap between the inner ring 20 and the inner plate 30, so that the internal space of the inner plate 30 is isolated from the external space, so as to achieve the purpose of sealing the inner plate 30, and then protect the cosmetic materials in the inner plate from being polluted or oxidized by external gases, and extend the protection period of the cosmetic materials. Optionally, mesh cloth is welded on the inner ring 20. When mesh cloth is welded on the inner ring 20, a relatively viscous foundation liquid can be stored in the inner plate 30, so as to achieve the effect of viscous foundation liquid combined with mesh cloth for consumers to take.
[0048] In a possible implementation, the inner ring 20 is provided with two seals, namely, a first seal 23 and a second seal 24. The present invention uses two seals to seal the inner cover 10 and the inner plate 30 respectively, thereby improving the sealing effect of the inner liner assembly as a whole, making the inner liner assembly suitable for air cushions with high airtightness requirements and the storage needs of some easily oxidized creams and powder blocks.
[0049] Optionally, the hardness of the ring body 21 is greater than the hardness of the first seal 23, and the hardness of the ring body 21 is greater than the hardness of the second seal 24. Optionally, the first seal 23 and the second seal 24 are made of elastic materials, and the ring body 21 and the seal can be made of materials with the same main components but different hardness, or can be made of two materials with different hardness. Using a material with high hardness to make the ring body 21 can meet the strength requirements of the inner ring, and using a material with low hardness and elasticity to make the first and second seals can meet the sealing requirements of the inner ring.
[0050] In a possible embodiment, the inner ring 20 is an integral part of two-color injection molding, the material of the ring body 21 includes PET material, and the material of the first seal 23 and the second seal 24 includes TPE material. As a practical embodiment, the main material of the ring body 21 can be PET material. In the present application, when the proportion of PET material is greater than 50%, the material can be considered as the main material of the ring body 21. Similarly, the main material of the first seal 23 and the second seal 24 can be TPE material. The material of the ring body 21 also includes TPU material or PETG material, wherein TPU (ThermoPlasticpolyUrethane) is thermoplastic polyurethane elastomer rubber, PET (PolyEthylene Terephthalate) is polyethylene terephthalate, and PETG (Poly(ethyleneterephthalateco-1,4-cylclohexylenedimethylene terephthalate)) is polyethylene terephthalate-1,4-cyclohexane dimethanol ester. TPE (Thermoplastic Elastomer) is a thermoplastic elastomer material. In this embodiment, the inner ring 20 is made of PET material with high hardness and good chemical resistance. The inner ring is not easy to dissolve when it contacts the cosmetic material, so it will not contaminate the cosmetic material, thereby reducing the risk of the packaging material contaminating the cosmetic material. In traditional liner components, the inner ring is usually made of polypropylene PP material. The PP inner ring is in contact with the cosmetic material for a long time and is prone to blending, that is, the PP material will melt in the cosmetic material, causing the chemical material to deteriorate or even fail to function. Since the PET material is harder than the PP material, the sealing difficulty of the PET inner ring is increased. The present application designs two independent seals on the inner ring 20 to seal the inner cover 10 and the inner plate 30 respectively, thereby meeting the sealing requirements of the inner ring.
[0051] like Figure 7-9 As shown, the upper end of the ring body 21 extends radially inward to form a support member 22, and the support member 22 is provided with a first gate 25 for molding the second sealing member 24. Figure 7As shown, the ring body 21 is an annular structure with openings at both ends. The upper end of the ring body radially inwardly forms a circle of support members 22 for supporting the mesh. The center of the support member 22 is a cavity, and the mesh can be fixedly installed on the support member 22. Figure 8 As shown, the support member 22 is provided with a first gate 25 for the inflow of molten material during injection molding.
[0052] like Figure 2 , Figure 5 , Figure 8 and Fig. 9 As shown, the inner wall of the support member 22 is provided with a groove 27, the first gate 25 is connected to the groove 27, the second sealing member 24 is formed in the groove 27 through the first gate 25, and the first sealing member 23 is formed on the outer wall of the ring body 21 through the second gate 28. Figure 2 As shown, the groove 27 is arranged near the inner side wall of the ring body 21, and the second sealing member 24 is located in the groove 27 to facilitate sealing of the inner disk 30. Figure 8 As shown, the inner ring 20 is also provided with a third gate 29 for molding the ring body 21. In a possible embodiment, the inner ring 20 is formed by injection molding of a two-color mold. The ring body 21 is made of PET material, and the first seal 23 and the second seal 24 are made of TPE material. During injection molding, the molten PET is injected into the mold through the third gate 29, and the molten TPE is injected into the mold through the first gate 25 and the second gate 28 respectively. After cooling, the inner ring 20 is demolded. Since the two seals and the ring body are molded in two colors, they are tightly combined and will not fall off. Since the first seal 23 and the second seal 24 are respectively molded on the inner side and the outer side of the inner ring 20, the first seal and the second seal are two independent components. The two seals seal the inner cover and the inner plate respectively, play a double sealing function, and improve the overall sealing performance of the liner assembly.
