SPECIFIC IMPLEMENTATIONS

[0019] The following describes the technical solutions in the embodiments of the present application clearly and completely with reference to the embodiments of the present application. Apparently, the embodiments described are merely some rather than all of the embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0020] It should be noted that the terms "first", "second" and so on in the description and claims of the present application and in the above accompanying drawings are intended to distinguish similar objects but do not necessarily indicate a specific order or sequence. It should be understood that the objects used in such a way may be exchanged under proper conditions to make it possible to implement the described implementations of this application in sequences except those illustrated or described herein. Moreover, the terms "include", "have" and their variants mean to cover a non-exclusive inclusion. For example, a process, method, system, product or device that includes a list of steps or units is not necessarily limited to those steps or units which are clearly listed. Instead, they may include other steps or units which are not expressly listed or inherent to such a process, method, product, or device.

[0021] For ease of description, spatially relative terms, such as "above", "on the upper side of", "on the upper surface of' and "on", can be used to describe the spatial positional relationship between components or features shown in the figure. It should be understood that the spatially relative terms are intended to encompass different orientations of the components in use or operation in addition to those shown in the figure. For example, if a component in the figure is inverted, it is described as a component "above other component or structure" or "on other component or structure". Therefore, the component will be positioned as "below other component or structure" or "under other component or structure". Therefore, the exemplary term "above" may include both orientations "above" and "below". The component may also be positioned in other different ways (rotated by 90 degrees or in other orientations), but the relative description of the space should be explained accordingly.

[0022] Embodiment 1: As shown in FIGS. 1-10, a cartridge assembly includes inner cap 10, inner ring 20, and inner pan 30. The inner ring 20 is disposed on the inner pan 30. The inner cap 10 is rotatably connected to the inner pan 30. The inner cap 10 can be closed onto the inner pan 30. The inner ring 20 includes ring body 21 as well as first sealing member 23 and second sealing member 24 that are fixedly disposed on the ring body 21. The inner cap 10 and the inner ring 20 are sealed by the first sealing member 23. The inner ring 20 and the inner pan 30 are sealed by the second sealing member 24.

[0023] The inner cap 10 is configured to accommodate a powder puff. The inner pan 30 is configured to accommodate a cosmetic such as a cushion, a cream or a pressed powder. For example, the pressed powder is a highlighter, a shadow, a lip glaze, etc. The inner ring 20 is disposed between the inner cap 10 and the inner pan 30. The inner ring 20 is configured to seal the inner pan 30. That is, the first sealing member 23 on the inner ring 20 is configured to seal a gap between the inner cap 10 and the inner ring 20, and the second sealing member 24 on the inner ring 20 is configured to seal a gap between the inner ring 20 and the inner pan 30, such that an internal space of the inner pan 30 is isolated from an external space to seal the inner pan 30. This protects the cosmetic in the inner pan from being contaminated or oxidized by the external gas and extends the shelf life of the cosmetic. Optionally, a mesh fabric is welded on the inner ring 20. When the mesh fabric is welded on the inner ring 20, a relatively viscous liquid foundation can be stored in the inner pan 30, such that the viscous liquid foundation cooperates with the mesh fabric in use.

[0024] In a possible implementation, two sealing members that are respectively the first sealing member 23 and the second sealing member 24 are disposed on the inner ring 20 in the present disclosure. The two sealing members are configured to respectively seal the inner cap 10 and the inner pan 30, thereby improving the overall sealing effect of the cartridge assembly. Therefore, the cartridge assembly is applied to storing cushions with high sealing requirements, as well as oxidation-prone creams and pressed powders.

[0025] Optionally, hardness of the ring body 21 is greater than hardness of the first sealing member 23. The hardness of the ring body 21 is greater than hardness of the second sealing member 24. Optionally, the first sealing member 23 and the second sealing member 24 are made of an elastic material. The ring body 21 and the sealing members may be respectively made of materials having a same main component but different hardness, and may also be respectively made of two materials with different hardness. With the high-hardness material for forming the ring body 21, the strength requirements of the inner ring can be met. With the low-hardness elastic material for forming the first sealing member and the second sealing member, the sealing requirements of the inner ring can be met.

[0026] In a possible implementation, the inner ring 20 is integrally formed by two-shot injection molding. A material of the ring body 21 includes PET. A material of the first sealing member 23 and the second sealing member 24 includes TPE. As a specific implementation, a main material of the ring body 21 may be the PET. In the present disclosure, when a proportion of the PET is greater than 50%, it is considered that the PET is the main material of the ring body 21. Similarly, a main material of the first sealing member 23 and the second sealing member 24 may be the TPE. The material of the ring body 21 further includes thermoplastic polyurethane (TPU) or poly(ethylene terephthalate-co-1,4-cyclohexylenedimethylene terephthalate) (PETG). The TPU is the thermoplastic polyurethane. The PET is the polyethylene terephthalate. The PETG is the poly(ethylene terephthalate-co-1,4-cyclohexylenedimethylene terephthalate). The TPE is the thermoplastic elastomer. In this implementation, the inner ring 20 is made of the PET with the high hardness and high chemical resistance. The inner ring is not susceptible to dissolution when coming into contact with the cosmetic, such that the cosmetic is not contaminated, thereby reducing the risk of the packaging material to contaminate the cosmetic. However, in the conventional cartridge assembly, the inner ring is typically made of PP. The PP inner ring is susceptible to dissolution when coming into contact with the cosmetic for a long time. That is, the PP material is dissolved into the cosmetic, leading to deterioration or even functional failure of the cosmetic. Since hardness of the PET is higher than hardness of the PP, the PET inner ring is sealed more difficultly. In the present disclosure, two independent sealing members on the inner ring 20 are configured to respectively seal the inner cap 10 and the inner pan 30, thus meeting the sealing requirements of the inner ring.

[0027] As shown in FIGS. 7-9, an upper end of the ring body 21 extends radially inward to form support member 22. First gate 25 configured to mold the second sealing member 24 is formed in the support member 22. As shown in FIG. 7, the ring body 21 is of an annular structure with an upper end and a lower end open. The upper end of the ring body extends radially inward to form the support member 22 for supporting the mesh fabric. A hollow cavity is formed in the support member 22. The mesh fabric can be fixedly disposed on the support member 22. As shown in FIG. 8, the first gate 25 to which a molten material flows during the injection molding is formed in the support member 22.

[0028] As shown in FIG. 2, FIG. 5, FIG. 8, and FIG. 9, an inner sidewall of the support member 22 is provided with groove 27. The first gate 25 communicates with the groove 27. The second sealing member 24 is molded in the groove 27 through the first gate 25. The first sealing member 23 is molded on an outer sidewall of the ring body 21 through second gate 28. As shown in FIG. 2, the groove 27 is close to an inner sidewall of the ring body 21. The second sealing member 24 is located in the groove 27 to seal the inner pan 30. As shown in FIG. 8, third gate 29 configured to mold the ring body 21 is further formed in the inner ring 20. In a possible implementation, the inner ring 20 is formed by injection molding with a two-shot mold, the ring body 21 is made of PET, and the first sealing member 23 and the second sealing member 24 are made of TPE. During the injection molding, molten PET is injected into the mold through the third gate 29, and molten TPE is injected into the mold through the first gate 25 and the second gate 28, and demolding is performed after cooling, thereby forming the inner ring 20. Since the two sealing members and the ring body are formed by the two-shot injection molding, they are closely attached without separation. Since the first sealing member 23 and the second sealing member 24 are respectively molded on an inner side and an outer side of the inner ring 20, the first sealing member and the second sealing member are two independent components. The two sealing members are respectively used to seal the inner cap and the inner pan, achieving a double sealing function and improving the overall sealing performance of the cartridge assembly.

[0029] As shown in FIG. 2, FIG. 5, FIG. 8, and FIG. 9, a lower end of the ring body 21 extends radially outward to form bump 26. The bump 26 is snap-fitted into the inner pan 30 to fix the inner ring 20 to the inner pan 30. The number of bumps 26 is not limited. There may be one, two, or more bumps. With the bump for hooking the inner pan 30, the bonding strength between the inner ring 20 and the inner pan 30 is improved.

[0030] As shown in FIG. 1, FIG. 2, and FIG. 6, the inner cap 10 is hinged to the inner pan 30. A lower end of the inner cap 10 extends axially downward to form engagement member 12. The engagement member 12 is hermetically attached to the first sealing member 23.

[0031] As shown in FIG. 5, the engagement member 12 extends outward along a radial direction of the inner cap 10 to form protrusion 14. As shown in FIG. 6, an upper end of the inner cap 10 extends radially outward to form flange 11. The inner cap 10 is of a disk-like structure with a sealed lower end, and an open upper end. The flange 11 is disposed at an opening of the upper end of the inner cap 10, so as to open the inner cap 10 conveniently. As shown in FIG. 2 and FIG. 5, the lower end of the inner cap 10 is provided with the engagement member 12. An inner sidewall of the engagement member 12 is hermetically attached to an outer sidewall of the first sealing member 23, thereby ensuring a sealing effect between the inner cap 10 and the inner ring 20. The protrusion 14 is disposed on the engagement member 12. The protrusion 14 is snap-fitted into the inner pan 30 to improve the bonding strength between the inner cap 10 and the inner pan 30.

[0032] As shown in FIG. 10, the inner pan 30 includes base plate 31 as well as first sleeve 32 and second sleeve 33 that are fixedly connected to the base plate 31. A gap is formed between the first sleeve 32 and the second sleeve 33. The inner ring 20 is disposed in the gap. The first sleeve 32 is located inside the second sleeve 33. First through hole 34 and second through hole 35 are formed in the second sleeve 33.

[0033] In a possible implementation, the inner cap 10 and the inner pan 30 are hinged together through a first hinge assembly. The first hinge assembly includes first lug 13, second lug 36, and first hinge shaft 15. As shown in FIG. 2, FIG. 6, and FIG. 10, first lug 13 is fixedly disposed on the inner cap 10, and the second lug 36 is fixedly disposed on the inner pan 30. During mounting, after the second lug 36 is inserted into the first lug 13, the first hinge shaft 15 passes through the first lug 13 and the second lug 36 to assemble the inner cap 10 and the inner pan 30 together.

[0034] As shown in FIG. 10, the first sleeve 32 and the second sleeve 33 are located on a same side of the inner pan 30. The cosmetic is placed in the first sleeve 32, and the inner ring 20 is disposed in the gap between the first sleeve 32 and the second sleeve 33. As shown in FIG. 5, the second sleeve 33 is hermetically attached to the second sealing member 24. The protrusion 14 on the inner cap 10 is snap-fitted into the first through hole 34, and the bump 26 on the inner ring 20 is snap-fitted into the second through hole 35, thereby improving the bonding strength between the inner cap and the inner pan, as well as between the inner ring and the inner pan.

[0035] Embodiment 2: As shown in FIGS. 11-14, a cosmetic container includes an outer casing assembly and a cartridge assembly detachably disposed in the outer casing assembly. After the cosmetic in the cartridge assembly is used up, the cartridge assembly can be detached from the outer casing assembly, and replaced with a new one. Hence, the outer casing assembly can be used repeatedly, reducing the resource waste.

[0036] The outer casing assembly includes outer cap 40 and base assembly 50 hinged to the outer cap 40. The base assembly 50 includes outer base 51 and inner base 52 that are fixedly snap-fitted together. The outer cap 40 and the base assembly 50 are fixed through snap-fit assembly 60. As shown in FIG. 11, in a possible implementation, an inner surface of the outer cap 40 is provided with mirror 41, and an outer surface of the outer cap 40 is provided with decorative member 42.
