[0002] The airtightness of the cushion compact's inner layer is crucial for ensuring product quality and user experience. A well-sealed inner layer effectively isolates the product from the external environment, maintaining internal cleanliness and preventing bacterial growth. However, if the inner layer is poorly sealed, bacteria, dust, and other microorganisms in the air can easily enter the foundation. Microorganisms thrive in warm, humid environments, leading to rapid reproduction. Long-term use of such cushion products can pose a potential threat to the user's skin health. Summary of the Invention

[0003] In view of the above-mentioned problems in the prior art, the purpose of this application is to solve the defect of poor sealing performance of the air cushion liner in the prior art.

[0004] To address the aforementioned issues, this application provides a cosmetic powder storage box, comprising a top cover, a clamping member, a sealing member, and a box groove. The top cover is used to cover the box groove. The sealing member is disposed within the box groove and located on the side of the box groove facing the top cover. The top cover has a mounting groove on the side facing the box groove. One end of the clamping member is disposed in the mounting groove, and the other end of the clamping member has a first extension portion and a second extension portion. The first extension portion and the second extension portion have a non-zero included angle. The box groove has a side wall, and the first extension portion can press against the side wall. The second extension portion is used to limit the sealing member.

[0005] Preferably, one end of the clamping member is a root portion, which is disposed in the mounting groove. An avoidance groove is provided between the first extension portion and the second extension portion. Along the setting direction of the sidewall, the cross-sectional shape of the clamping member is V-shaped.

[0006] Preferably, the second extension extends in a direction away from the first extension and protrudes relative to the bottom surface of the top cover.

[0007] Preferably, the sealing element has a mesh fabric on the side surface facing the top cover, and the protruding portion of the second extension can limit the mesh fabric.

[0008] Preferably, a gap of 0.05-0.1 mm is provided between the second extension portion and the seal.

[0009] Preferably, the material of the top cover is polyethylene terephthalate, and / or the material of the clamping member is thermoplastic elastomer.

[0010] Preferably, the first extension portion is parallel to the sidewall.

[0011] Preferably, along the orientation of the sidewall, the length by which the first extension portion is embedded into the mounting groove is the same as the length by which the first extension portion extends relative to the top cover.

[0012] Preferably, the sidewall has a groove on the side facing the first extension portion, and the first extension portion can be inserted into the groove for sealing.

[0013] A cosmetic packaging box, comprising the cosmetic powder storage box described in any of the above claims.

[0014] Based on the above technical solutions, the cosmetic powder storage box and cosmetic packaging box described in this application have the following beneficial effects:

[0015] By pressing the first extension of the clamping member against the side wall of the box groove, a seal is achieved at the connection point when the top cover rotates relative to the box groove to open and close the cosmetic powder storage box. Simultaneously, the second extension of the clamping member limits the sealing element and clamps it between the top cover and the box groove, ensuring a seal at the contact surface between the top cover and the box groove. Thus, the synergistic sealing performance of the clamping member and the sealing element guarantees the overall airtightness of the cosmetic powder storage box, effectively preventing the cosmetic powder from becoming damp, oxidized, and contaminated, thus ensuring product quality. Furthermore, when using the cosmetic powder storage box, simply placing the top cover on the box groove allows the clamping member to automatically press against the side wall, achieving a seal. This improves the convenience of sealing the cosmetic powder storage box during use, providing users with a convenient and hygienic cosmetic experience. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0034] The term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this application. In the description of this application, it should be understood that the terms "upper," "lower," "left," "right," "top," "bottom," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Moreover, the terms "first," "second," etc., are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0035] like Figures 1-15 As shown in the figure, this application discloses a cosmetic powder storage box 100, which can also be referred to as a replacement core. The cosmetic powder storage box 100 includes a top cover 11, a clamping member 12, a sealing member 13, and a box groove 14.

[0036] The upper cover 11 is used to cover the box groove 14. The sealing member 13 is disposed in the box groove 14 and located on the side of the box groove 14 facing the upper cover 11. The upper cover 11 has a mounting groove 111 on the side facing the box groove 14. One end of the pressing member 12 is disposed in the mounting groove 111. The other end of the pressing member 12 has a first extension portion 121 and a second extension portion 122. The first extension portion 121 and the second extension portion 122 have a non-zero included angle. The box groove 14 has a side wall 141. The first extension portion 121 can press against the side wall 141. The second extension portion 122 is used to limit the sealing member 13.

[0037] It is understood that the non-zero included angle between the first extension portion 121 and the second extension portion 122 means that the first extension portion 121 and the second extension portion 122 extend toward different sides respectively; preferably, they extend in opposite directions, that is, the first extension portion 121 and the second extension portion 122 extend in opposite directions.

[0038] In the embodiments of this application, the included angle between the first extension portion 121 and the second extension portion 122 can be 30°, 45° or 60°, and can be adjusted according to actual needs.

[0039] It is understood that the clamping member 12 is elastic, so when the upper cover 11 is in the open state relative to the box groove 14, the clamping member 12 can be in a normal, unpressed state; when the upper cover 11 is closed on the box groove 14, the first extension portion 121 of the clamping member 12 can contact the side wall 141 of the box groove 14 and be pushed by the upper cover 11 to press against the side wall 141.

[0040] Therefore, based on the above structural form, the sealing of the connection point when the upper cover 11 rotates relative to the box groove 14 to open and close the cosmetic powder storage box 100 is achieved by the compression contact between the first extension portion 121 of the clamping member 12 and the side wall 141 of the box groove 14. At the same time, the sealing of the cosmetic powder storage box 100 is achieved by limiting the sealing member 13 by the second extension portion 122 and clamping the sealing member 13 between the upper cover 11 and the box groove 14. Thus, the overall sealing performance of the cosmetic powder storage box 100 is guaranteed by the synergistic sealing performance of the clamping member 12 and the sealing member 13, effectively preventing the cosmetic powder from getting damp, oxidized and contaminated, and ensuring product quality. Furthermore, when the cosmetic powder storage box 100 is in use, the upper cover 11 only needs to be closed on the box groove 14, and the clamping member 12 will automatically press against the side wall 141 to achieve a seal, which improves the convenience of sealing the cosmetic powder storage box 100 during use and provides users with a convenient and hygienic cosmetic use experience.

[0041] In this embodiment of the application, the material of the upper cover 11 is polyethylene terephthalate (PET), and / or the material of the clamping member 12 is thermoplastic elastomer (TPE).

[0042] PET is a thermoplastic polyester with good mechanical properties, heat resistance, and chemical resistance. It is transparent, tough, and not easily broken, so it can provide structural strength and shape stability in the cover 11. TPE is a thermoplastic plastic with rubber elasticity, which combines the processing performance of plastic and the elasticity of rubber. TPE material is soft, easy to mold, and has good sealing performance and impact resistance. Therefore, it can not only provide a sealing effect in the clamping part 12, but also increase the fit with the cover 11.

[0043] In this embodiment, the clamping member 12 and the top cover 11 are independently configured entities, manufactured using a two-color injection molding process to ensure a tight connection between the two materials.

[0044] Therefore, by adopting the above-described structure of the top cover 11 and the clamping member 12, it is ensured that the clamping member 12 can achieve its sealing effect with the box groove 14, while also ensuring the connection strength between the clamping member 12 and the top cover 11. This ensures that the clamping member 12 will not detach from the top cover 11 when the top cover 11 is opened or closed, thus maintaining the integrity of the cosmetic powder storage box 100. In summary, the above design achieves the dual functions of sealing and connection.

[0045] This design not only solves the problem of not adding a sealing clamping element 12 at the top cover 11 in the prior art, but also solves the defect that the previous sealing clamping element 12 could not simultaneously guarantee sealing and structural strength. Specifically, in the prior art, those skilled in the art would not consider setting a clamping element 12 that needs to be squeezed countless times on a moving part, let alone setting a clamping element 12 at the bottom of the top cover 11. In addition, in order to ensure the sealing effect of the clamping element 12, the existing technology generally reduces its own structural strength and makes the clamping element 12 softer. However, a softer clamping element 12 will have the defect that it cannot be fixed to the top cover 11, and is prone to problems such as shaking, sliding, deformation and displacement. In order to ensure the structural strength of the connection between the clamping element 12 and other parts, its own hardness is generally increased and the clamping element 12 is made harder. However, a harder clamping element 12 will greatly reduce its sealing performance with the box groove 14. Therefore, the clamping member 12 with the above-mentioned structural form adopted in this application can be regarded as an independent entity, while ensuring its linkage and coordination with the other components in the cosmetic powder storage box 100. It ensures that the upper cover 11 squeezes the clamping member 12 to achieve its sealing performance, and ensures the connection reliability of the clamping member 12 at the bottom of the upper cover 11. Overall, it achieves the triple effect of sealing, squeezing and fixing of the clamping member 12, ensuring that the clamping member 12 not only meets the structural strength of its connection with the upper cover 11, but also provides a good sealing effect.

[0046] In other embodiments, the top cover 11 and the clamping member 12 may also be an integrally formed structure.

[0047] As a preferred implementation method, such as Figure 8 As shown, the gate of the upper cover 11 is located on the side of the upper cover 11 facing the box groove 14 and is located at the center of the upper cover 11; the gate of the clamping member 12 is two, which are symmetrically arranged on both sides of the cover.

[0048] like Figure 2 As shown, one end of the clamping member 12 is a root 123, which is disposed in the mounting groove 111. An avoidance groove 124 is provided between the first extension portion 121 and the second extension portion 122. Along the setting direction of the side wall 141, the cross-sectional shape of the clamping member 12 is V-shaped.

[0049] It is understood that the V-shape is an inverted V-shape, and the opening of the clamping part is set downwards. The root 123 of the clamping member 12 is fixedly set in the mounting groove 111 to stabilize the clamping member 12.

[0050] In this embodiment, the root 123 of the clamping member 12 is a pointed structure so as to be inserted into the mounting groove 111 of the upper cover 11; in other embodiments, the structure of the root 123 of the clamping member 12 can be set as a planar structure, rounded corners or other irregular shapes, and the specific structural design can be based on the structure of the mounting groove 111, which is not limited here.

[0051] In the embodiments of this application, the included angle of the V-shape can be 60°, 90°, or other angles, depending on the required elasticity and sealing force. For example, a 90° V-shaped cross-section can provide stronger compressive force to the sidewall 141, thereby maximizing the deformation of the clamping member 12 and ultimately maximizing its sealing performance.

[0052] Therefore, based on the above structural form, by setting the clamping member 12 into a V shape, the elastic extrusion force of the clamping member 12 is improved, making the seal more secure and maintaining good sealing performance even under long-term use.

[0053] In a preferred embodiment, the second extension 122 extends in a direction away from the first extension 121 and protrudes relative to the bottom surface of the top cover 11. The degree of protrusion can be based on the amount of pressure required to be applied to the seal 13.

[0054] By extending the second extension 122 in a direction away from the first extension 121, the clamping member 12 can effectively apply uniform pressure to the seal 13, thereby improving the sealing performance; by designing the second extension 122 to protrude relative to the bottom surface of the top cover 11, it is ensured that the seal 13 will not shift when subjected to pressure, thereby maintaining a good sealing state.

[0055] In this embodiment of the application, the sealing member 13 has a mesh fabric on the side surface facing the upper cover 11, and the protruding portion of the second extension portion 122 can limit the mesh fabric.

[0056] In the embodiments of this application, the mesh can filter out impurities in the powder, ensuring the purity of the cosmetic during use, and also helps to release the cosmetic powder evenly, avoiding excessive release at one time.

[0057] Preferably, a gap of 0.05-0.1 mm is provided between the second extension portion 122 and the seal 13. This setting avoids excessive compression of the seal 13 due to an excessively small gap, which would affect its elasticity and sealing effect; while an excessively large gap may lead to a poor seal. Therefore, the gap of 0.05-0.1 mm is optimized to balance pressure and sealing effect.

[0058] In a preferred embodiment, the first extension portion 121 and the sidewall 141 are parallel.

[0059] Understandably, the extension direction of the first extension portion 121 is the same as the setting direction of the side wall 141. This design ensures that when the first extension portion 121 is subjected to pressure, it can apply pressure evenly along the side wall 141, thereby achieving an effective seal. Furthermore, it ensures that when the top cover 11 is closed, the first extension portion 121 can slide or press evenly along the side wall 141 without generating unnecessary friction or resistance. In addition, it ensures that the clamping member 12 achieves a sealing effect on the top cover 11 while also ensuring that the clamping member 12 is fixedly installed within the top cover 11.

[0060] In a preferred embodiment, along the setting direction of the sidewall 141, the length by which the first extension portion 121 is embedded into the mounting groove 111 is the same as the length by which the first extension portion 121 extends relative to the top cover 11.

[0061] It is understood that the first extension 121 embedded in the mounting groove 111 is the first part, and the part extending out relative to the mounting groove 111 is the second part, and the length of the first part and the length of the second part are the same.

[0062] Based on the above structural form, it is ensured that the force of the first extension portion 121 in the clamping member 12 can be evenly distributed, and equal pressure can be applied inward and outward. Since the two parts of the first extension portion 121 have the same length, the force can be balanced in two directions. The uniform pressure distribution can also improve the overall stability of the cosmetic powder storage box 100 and reduce potential failures caused by uneven pressure. In addition, it also ensures that when the cover 11 is closed, the first extension portion 121 can accurately apply pressure to the side wall 141 without uneven pressure due to length differences.

[0063] In a preferred embodiment, the sidewall 141 has a groove 142 on the side facing the first extension portion 121, and the first extension portion 121 can be embedded into the groove 142 for sealing.

[0064] It is understandable that the structure of the groove 142 is adapted to the contact area of ​​the first extension 121. In this way, when the cover 11 is closed, the first extension 121 will be pressed into the groove 142 of the side wall 141 to effectively block the direct contact between the cosmetic powder and the outside world and prevent the powder from being contaminated.

[0065] This application also discloses a cosmetic packaging box, which includes an outer shell (not shown in the figure) and the cosmetic powder storage box 100 described above. The cosmetic powder storage box 100 is disposed in the outer shell. After the material in the cosmetic powder storage box 100 is used up, a new cosmetic powder storage box 100 filled with material can be replaced for the user's reuse.

[0066] The foregoing description has fully disclosed the specific embodiments of this application. It should be noted that any modifications made by those skilled in the art to the specific embodiments of this application do not depart from the scope of the claims. Accordingly, the scope of the claims of this application is not limited to the foregoing specific embodiments.
