Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging technology, and in particular to a powder box with a replaceable inner liner. Background Technology

[0002] In the cosmetics industry, powder compacts are widely popular due to their portability and ease of use. Traditional powder compacts are mostly one-piece designs, with outer shells typically made of metal, ceramic, or high-quality plastic, and adorned with mirrored surfaces, exquisite decorative patterns, or electroplating to meet consumers' demands for aesthetics and texture. However, this pursuit of aesthetics often comes at the cost of higher manufacturing costs. Once the powder inside is used up, consumers usually discard the entire compact, which not only wastes resources but also makes the cost per use relatively high.

[0003] To reduce long-term operating costs and minimize resource waste, replaceable cartridge designs have emerged in the market. These cartridges typically consist of a reusable, aesthetically pleasing outer shell and a removable, separately sold inner cartridge that primarily holds the toner. When the toner in the inner cartridge is depleted, consumers simply purchase a new replacement cartridge to insert into the existing shell and continue using the cartridge without discarding the entire cartridge structure.

[0004] However, existing replaceable inner container designs still have significant room for improvement, especially in terms of cost control. To ensure the airtightness of the powder during transportation, storage, and when not encased in the outer shell, preventing powder leakage, moisture, or contamination, existing replaceable inner containers are generally equipped with a separate sealing cap. This cap usually needs to fit precisely with the inner container body and may include additional sealing rings, snap-fit ​​structures, or threaded locking devices. While this design does effectively ensure the freshness and safety of the powder, it also introduces the following problems: the manufacture of the additional cap requires more plastic or other packaging materials; the cap and its mating structure with the inner container increase the complexity of the molds and production processes, raising the production cost per unit of inner container.

[0005] Therefore, although the original design intention of replaceable inner liners was to reduce overall usage costs and waste, the independent cap structure required in existing solutions to ensure airtightness has become a significant factor driving up the cost of the replacement inner liner itself. This prevents the expected cost advantage of replacing the inner liner from being fully realized, and even partially offsets the cost savings from reusing the outer shell. Consumers still need to bear relatively high replacement consumable costs during long-term use. Utility Model Content

[0006] This utility model addresses the shortcomings of existing technologies by providing a replaceable inner container powder cartridge. This replaceable inner container powder cartridge has the inner container sealing cap designed on the cartridge body, so the replaceable inner container does not need to include the inner container sealing cap, further reducing the consumable cost of the replaceable inner container.

[0007] To solve the aforementioned technical problems, this utility model provides the following technical solution: a replaceable powder cartridge includes a cartridge body with an openable lid. The cartridge body has receiving portions with openings on both the top and bottom sides. A replaceable inner cartridge is housed within each receiving portion. The replaceable inner cartridge includes a powder receiving cavity with a powder dispensing port at the top. An inner cartridge sealing cap is rotatably connected to the cartridge body, and the bottom of the inner cartridge sealing cap has an annular protrusion for sealing the powder dispensing port. This replaceable powder cartridge directly connects the inner cartridge sealing cap to the reusable cartridge body. When replacing the replaceable inner cartridge, there is no need to replace the inner cartridge sealing cap; that is, the replaceable inner cartridge does not need to include the inner cartridge sealing cap, further reducing the consumable cost of the replaceable inner cartridge.

[0008] In the above technical solution, preferably, the replaceable inner liner includes a mesh tray assembly covering the powder dispensing port. The mesh tray assembly is provided with an annular elastomer, which cooperates with the annular convex ring to seal the powder dispensing port. The mesh on the mesh tray assembly is used to prevent excessive powder from pouring out of the powder containing cavity, and the annular elastomer can cooperate with the annular convex ring to improve the sealing performance of the powder dispensing port.

[0009] In the above technical solution, preferably, the replaceable inner liner has an annular groove around the outer periphery of the powder dispensing port, the edge of the mesh tray assembly is engaged within the annular groove, and the annular elastomer provides an interference seal to the outer ring of the annular groove. The annular elastomer includes a protruding elastic sealing ring, the outer end of which fits against the inner wall of the annular convex ring to seal the powder dispensing port. This structure further improves the sealing performance of the powder dispensing port through the interference seal between the annular elastomer and the outer ring of the annular groove, and the fit between the elastic sealing ring and the inner wall of the annular convex ring.

[0010] In the above technical solution, preferably, a first annular protrusion is provided on the annular wall of the annular groove, and a first annular fastening groove is provided on the mesh tray assembly. The first annular protrusion is embedded in the first annular fastening groove to position the mesh tray assembly on the replaceable inner liner. This structure further improves the positioning reliability of the mesh tray assembly and the replaceable inner liner.

[0011] In the above technical solution, preferably, a second annular groove is provided on the outer annular wall of the annular groove, and a positioning protrusion is provided on the outer wall of the annular convex ring to be embedded in the second annular groove for positioning the inner liner sealing cap. This structure further improves the positioning reliability between the inner liner sealing cap and the replaceable inner liner.

[0012] In the above technical solution, preferably, the box body includes a base and a shoulder sleeve. The shoulder sleeve has a shaft slot with a bottom opening on its side, and the inner liner sealing cover has a rotating shaft on its side. The rotating shaft is inserted into the shaft slot from the bottom opening, and the shoulder sleeve is engaged with the box body to limit the rotation of the rotating shaft. This structure facilitates the assembly of the rotating connection structure between the inner liner sealing cover and the box body.

[0013] In the above technical solution, preferably, the box cover is hinged to the shoulder sleeve.

[0014] In the above technical solution, preferably, the top of the inner liner sealing cover is provided with a powder puff receiving groove, and a powder puff is provided in the powder puff receiving groove.

[0015] In the above technical solution, preferably, both the box body and the box lid are provided with magnets that can attract each other. This structure can effectively prevent the box lid from opening accidentally and improves the user experience.

[0016] In the above technical solution, preferably, the inner wall of the powder receiving cavity is provided with an elastic sheet, the elastic sheet is provided with a protrusion, and the outer periphery of the replaceable inner liner is provided with a third annular groove that matches the protrusion. This structure facilitates the replacement of the replaceable inner liner. The replaceable inner liner can be detached from the box body by pushing it upward through the opening at the bottom of the receiving part, and the replaceable inner liner can be inserted through the opening at the top of the receiving part and pressed downward until the protrusion is embedded in the third annular groove to complete the replacement of the replaceable inner liner.

[0017] Compared with the prior art, this utility model has the following advantages: This replaceable powder box connects the inner liner sealing cap directly to the reusable box body. When replacing the replaceable inner liner, there is no need to replace the inner liner sealing cap. In other words, the replaceable inner liner does not need to include the inner liner sealing cap, which further reduces the consumable cost of the replaceable inner liner.
