[0001] This application relates to the field of cosmetic packaging technology, and in particular to a cosmetic powder storage container and a cosmetic powder storage box. Background Technology

[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

[0008] Preferably, one of the convex rings is disposed at the bottom end of the first portion, and the sealing ring abuts against the convex ring.

[0009] Preferably, the powder storage container further includes a flip cover for closing the box body. The flip cover has an extension on the side facing the box body, and the extension can extend into the predetermined interval to contact the sealing ring to seal the flip cover and the box body.

[0010] Preferably, the sealing ring has a protruding structure at the end facing the extension section, the protruding structure being used to contact the extension section; Along the extension direction of the extension section, a clearance groove is provided below the protruding structure, which is used to accommodate the protruding structure that has been squeezed and deformed by the extension section.

[0011] Preferably, the hardness value of the sealing ring is less than the hardness value of the flip cover but greater than the hardness value of the airtight component.

[0036]

Example 1

[0037] The box body 14 has an inner sidewall 141 and an outer sidewall 142, with a predetermined interval between the inner sidewall 141 and the outer sidewall 142. The airtight component 12 includes a first part 121 and a second part 122. The first part 121 and the sealing ring 13 are both disposed in the predetermined interval. The first part 121 is in contact with the inner sidewall 141 by compression through the sealing ring 13. The second part 122 can cover the top of the inner sidewall 141.

[0038] In this embodiment, the inner wall 141 and the outer wall 142 are arranged in parallel, which ensures the stability of the internal space of the powder storage container and facilitates material storage and the installation of the airtight component 12.

[0039] It is understood that the space enclosed by the inner wall 141 is a receiving cavity 147, which is used to store materials, and the space enclosed by the inner wall 141 and the outer wall 142 is used to place the airtight component 12 and the sealing ring 13.

[0040] Preferably, the predetermined interval is in the range of 5-8 mm.

[0041] In a preferred embodiment, the airtight component 12 has a sealing ring on the side facing the inner wall 141, and the sealing ring and the top of the inner wall 141 are press-fitted. This arrangement ensures that the sealing performance remains stable even when the powder storage container is subjected to vibration or pressure changes, and the press-fit between the sealing ring and the inner wall 141 can effectively prevent the penetration of air and moisture, thereby improving the sealing performance of the powder storage container.

[0042] In a preferred embodiment, the airtight component 12 is an annular structure, surrounding the periphery of the inner wall 141. The annular structure can evenly distribute pressure, ensuring that there are no gaps between the top of the entire inner wall 141 and the airtight component 12, thereby achieving a better sealing effect.

[0043] Therefore, based on the above structural form, the first part 121 is pressed into contact with the inner wall 141 by the sealing ring 13, so that the first part 121 of the airtight component 12 is tightly attached to the inner wall 141 under the action of the sealing ring 13, forming a first sealing barrier. Furthermore, the second part 122 forms a second sealing barrier with the inner wall 141 by covering the top of the inner wall 141. The double sealing ensures that the material is not contaminated by the outside. In addition, by setting a predetermined interval, sufficient space can be provided for the airtight component 12 and the sealing ring 13, while maintaining the compactness of the overall structure of the powder storage container.

[0044] As a preferred embodiment, the inner diameter of the sealing ring 13 is smaller than the inner diameter of the airtight component 12. The purpose of this arrangement is that when the sealing ring 13 is fitted onto the airtight component 12, it can always provide a compressive force towards the airtight component 12, that is, always fix the airtight component 12 on the inner sidewall 141 to form an airtight effect.

[0045] like Figure 7 As shown, along the setting direction of the inner sidewall 141, the cross-sectional shape of the airtight component 12 is L-shaped.

[0046] It is understandable that the shape of the airtight component 12 is an inverted L-shape, that is, the first part 121 and the second part 122 are arranged perpendicularly.

[0047] Therefore, based on the above structural form, the L-shaped cross-section design allows the airtight component 12 to better adapt to the shape of the inner wall 141, forming an effective sealing barrier, reducing potential leakage points on the sealing surface, ensuring a tighter contact between the airtight component 12 and the inner wall 141, reducing the risk of poor sealing, and improving the overall sealing effect. Furthermore, the L-shaped structure provides better support, making the airtight component 12 less prone to deformation under external pressure, enabling even pressure distribution, reducing local stress concentration, thereby maintaining the sealing and stability of the powder storage container, and reducing the risk of damage to the airtight component 12 due to excessive pressure. In addition, because the L-shaped airtight component 12 has a unique orientation during installation, it reduces the possibility of installation errors. Therefore, if the airtight component 12 needs to be replaced, its well-defined structure allows for quick positioning and replacement, thus simplifying the installation process and making operation easier.

[0048] Furthermore, in this embodiment, the airtight component 12 is made of polyethylene terephthalate (PET), the sealing ring 13 is made of nitrile rubber (NBR) or silicone, and the box body 14 is made of polyethylene terephthalate (PET). PET is a thermoplastic polyester with good mechanical properties, heat resistance, and chemical resistance. It is transparent, tough, and not easily broken, thus providing structural strength and shape stability in the sealing ring 13. NBR is a synthetic rubber with excellent oil resistance, chemical resistance, and heat resistance. It has good resistance to various oils, solvents, and chemicals, making it suitable for sealing in cosmetic cushion foundations. Silicone is a synthetic rubber with excellent heat resistance, cold resistance, electrical insulation, and oxidation resistance. It maintains stable physical properties over a wide temperature range and has good resistance to many chemicals.

[0049] Therefore, considering that the cosmetic powder storage container 100 may come into contact with various cosmetic ingredients, including oils and fragrances, the chemical resistance of NBR and silicone can prevent the sealing ring 13 from degrading due to contact with these ingredients, thereby maintaining a long-term sealing effect. Secondly, both NBR and silicone have good elasticity, which allows the sealing ring 13 to deform under pressure, thereby tightly fitting the contact surfaces of the airtight component 12 and the box body 14 to form an effective sealing barrier. Furthermore, the softness and elasticity of NBR and silicone ensure that they can fit tightly with the airtight component 12, and there will be no leakage even after long-term use. Finally, the easy processing of NBR or silicone materials allows for the manufacture of sealing rings 13 that are precisely adapted to various box body 14 structures, matching the predetermined interval between the inner sidewall 141 and the outer sidewall 142 of the box body 14.

[0050] Therefore, the sealing ring 13 and airtight component 12 with the above-described structure ensure that they can achieve both their sealing effect and the connection strength between them and the box body 14. This solves the problem that the sealing ring 13 with sealing performance could not simultaneously guarantee sealing and structural strength. Specifically, in order to ensure the sealing effect of the sealing ring 13 with sealing performance, the existing technology generally reduces its own structural strength by making the sealing ring 13 softer. However, a softer sealing ring 13 will have the defect of not being able to fit into the box body 14, and is prone to problems such as shaking, sliding, deformation and displacement. In order to ensure the structural strength of the connection between the sealing ring 13 and other components, its own hardness is generally increased, making the sealing ring 13 harder. However, a harder sealing ring 13 will greatly reduce its own sealing performance. Therefore, the sealing ring 13 and airtight component 12 with the above-mentioned structural form adopted in this application can be treated as independent entities while ensuring their linkage and coordination with other components in the powder storage container. This ensures the compression of the sealing ring 13 and the snap-fit ​​between the two and the box body 14. Overall, the three effects of sealing, compression and fixation are achieved, ensuring that the two meet the structural strength requirements of their connection with the box body 14 and provide a good sealing effect.

[0051] In a preferred embodiment, the thickness of the first portion 121 is not less than the thickness of the inner sidewall 141 in the radial direction along the direction in which the outer sidewall 142 is disposed.

[0052] For example, if the setting direction of the outer wall 142 is defined as the vertical direction, then along the horizontal direction, the thickness of the first part 121 is not less than the thickness of the inner wall 141.

[0053] The thicker design of the first part 121 can enhance the overall structural strength of the airtight component 12, making it less prone to deformation or damage when subjected to external pressure or impact, thereby maintaining the sealing performance. It can also form a stable sealing interface between the airtight component 12 and the inner wall 141, reducing the problem of uneven sealing caused by thickness differences.

[0054] like Figure 2 and Figure 7 As shown, the first part 121 is provided with a plurality of protrusions, all of which are disposed on the side opposite to the second part 122, and the plurality of protrusions are arranged sequentially at intervals along the extending direction of the first part 121. The sealing ring 13 has a groove on the side facing the airtight component 12. The groove is adapted to at least one of the convex rings to limit the airtight component 12 and ensure the stability and accuracy of the seal.

[0055] In a preferred embodiment, the plurality of convex rings are arranged in parallel. The parallel arrangement of the convex rings can evenly distribute the pressure and reduce deformation or damage caused by excessive pressure on a single convex ring.

[0056] In a preferred embodiment, multiple convex rings are evenly spaced along the extension direction of the first portion 121 to ensure uniformity and stability of the seal.

[0057] As a preferred embodiment, the depth and width of the groove are slightly larger than the diameter of the convex ring so that the convex ring can smoothly enter the groove and achieve positioning.

[0058] Preferably, one of the convex rings is disposed at the bottom end of the first portion 121, and the sealing ring 13 abuts against the convex ring.

[0059] In this embodiment of the application, there are two protrusions, including a first protrusion 123 and a second protrusion 124. The first protrusion 123 is adapted to the groove of the sealing ring 13 so that the sealing ring 13 can fix the airtight component 12 on the inner sidewall 141. The second protrusion 124 is disposed at the bottom end of the sealing ring 13 so that the airtight component 12 can be fixed on the box body 14 by itself.

[0060] In a preferred embodiment, the first convex ring 123 is located at the upper end of the first portion 121, and the second convex ring 124 should be located at the bottom end.

[0061] Therefore, the double fixing effect of the two convex rings makes the airtight component 12 more firmly fixed in the box 14, improving the stability and reliability of the seal; the second convex ring 124 abuts against the sealing ring 13, preventing the sealing ring 13 from falling off due to external force during use, and ensuring long-term sealing effect.

[0062] like Figure 2 and Figure 6 As shown, the powder storage container also includes a flip cover 11, which is used to cover the box body 14. The flip cover 11 has an extension section 111 on the side facing the box body 14. The extension section 111 can extend into the predetermined interval and contact the sealing ring 13 to seal the flip cover 11 and the box body 14.

[0063] In a preferred embodiment, the extension 111, the inner sidewall 141, and the outer sidewall 142 are all arranged in parallel.

[0064] Specifically, the contact with the seal is defined as contact with the top end of the outer side of the sealing ring 13.

[0065] Therefore, the design of the extension section 111 allows the flip cover 11 to directly contact the sealing ring 13 when the box body 14 is closed, thereby forming an effective sealing barrier between the flip cover 11 and the box body 14 to prevent cosmetic powder from being contaminated by external factors. Furthermore, since the extension section 111, the inner sidewall 141, and the outer sidewall 142 are all arranged in parallel, wear caused by uneven pressure can be reduced. At the same time, the design of the extension section 111 simplifies the closing operation of the flip cover 11; after use, simply close the flip cover 11, and the extension section 111 will automatically contact the sealing ring 13 along the direction of the sidewall, without requiring additional adjustment or alignment steps.

[0066] like Figure 14 As shown, the end of the sealing ring 13 facing the extension section 111 is provided with a protruding structure 131, which is used to contact the extension section 111 to form a sealing point; Along the extension direction of the extension section 111, a relief groove 132 is provided below the protruding structure 131. The relief groove 132 is used to accommodate the protruding structure 131 that is deformed by the extension section 111. That is, the relief groove 132 can accommodate the deformation of the protruding structure 131 when it is squeezed by the extension section 111, so as to avoid damage to the protruding structure 131 due to excessive compression and extend the service life of the sealing ring 13.

[0067] In a preferred embodiment, the bottom end of the sealing ring 13 is provided with a guide slope 133, which is used to guide the assembly of the sealing ring 13, providing guidance for the assembly of the sealing ring 13 and improving assembly efficiency.

[0068] like Figure 2 and Figure 14 As shown, the sealing ring 13 is provided with a sealing rib 134 on the side facing the outer wall 142. The sealing rib 134 is used to press against the outer wall 142 to achieve the limiting and fixing of the sealing ring 13.

[0069] In a preferred embodiment, the hardness value of the sealing ring 13 is less than that of the flip cover 11 and greater than that of the airtight component 12. This gradient design of hardness value is to ensure that the sealing ring 13 can effectively buffer and seal between the airtight component 12 and the flip cover 11 when the powder storage container is closed.

[0070] Specifically, the hardness value of the sealing ring 13 is in the range of 50%-90% of the hardness value of the flip cover 11, and the hardness value of the sealing ring 13 is 10%-50% higher than the hardness value of the airtight component 12.

[0071] In this way, the hardness value of the sealing ring 13 is designed to be moderate, which can ensure that when the powder storage container is closed, the sealing ring 13 can effectively squeeze the airtight component 12 and fill any potential gaps between the airtight component 12 and the inner sidewall 141, thereby achieving a better sealing effect. In addition, it ensures that when the extension section 111 of the flip cover 11 squeezes the sealing ring 13, it can also ensure the sealing between the flip cover 11 and the box body 14.

[0072] In this embodiment, the flip cover 11 has a storage slot 112 on the side away from the box body 14 for storing makeup tools, such as powder puffs and brushes. Furthermore, a handle 113 is provided on the outer edge of the storage slot 112 for the user to open and close the flip cover 11.

[0073] Preferably, a hinge protrusion 114 is provided on the opposite side of the hand buckle 113, and a hinge seat 143 is provided on the box body 14 at the position corresponding to the hinge protrusion 114. The hinge protrusion 114 and the hinge seat 143 are adapted to accommodate cylindrical objects such as pins, thereby realizing the rotatable connection between the flip cover 11 and the box body 14. The assembly method includes at least the following two: First, the pin can penetrate the hinge protrusion 114 and the hinge seat 143, in which case one pin is sufficient; Second, the pin does not penetrate the hinge protrusion 114 and the hinge seat 143, in which case two pins are required to be set opposite each other.

[0074] In this embodiment of the application, both the flip cover 11 and the box body 14 are square with rounded top corners.

[0075] In this embodiment of the application, a closing protrusion 115 is provided on the outer wall surface of the extension section 111, preferably three, and the three closing protrusions 115 are respectively provided on the other three sides except for the hinge protrusion 114. The box body 14 is provided with a closing groove 144 at the position corresponding to the closing protrusion 115. The closing protrusion 115 and the closing groove 144 are adapted to achieve the snap-fit ​​between the flip cover 11 and the box body 14.

[0076] In this embodiment of the application, the gate of the flip cover 11 is located on the side of the flip cover 11 facing the box body 14 and is located at the center of the flip cover 11.

[0077] In this embodiment, the airtight component 12 has a PET patch on the side surface facing the flip cover 11, and the distance between the bottom surface of the storage groove 112 and the patch is in the range of 0.2-0.4mm, so as to limit the patch and prevent the patch from opening.

[0078] In this embodiment, the flip cover 11 is made of polyethylene terephthalate (PET), and its effects are as described above, so they will not be repeated here.

[0079] Furthermore, the inner wall 141 has an irregular shape on the side facing the first portion 121; and / or, the outer wall 142 has an irregular shape on the side facing the sealing ring 13.

[0080] Understandably, the wall surface is not smooth, but rather has variations in shape, texture, or other geometry to increase the contact area with the sealing ring 13. For example, the inner wall 141 may be designed with vertical or horizontal grooves that increase the contact area with the first portion 121 of the airtight component 12; the irregular shape of the outer wall 142 may be a convex or concave surface, a spiral shape, or other complex surface structure.

[0081] Therefore, by setting irregularly shaped walls, the contact area with the airtight component 12 or sealing ring 13 can be significantly increased, thereby improving the stability of the connection and increasing the friction between components, resulting in a more secure seal and reducing the risk of leakage. At the same time, irregularly shaped walls can distribute pressure, reduce localized wear, and extend the service life of powder storage container components.

[0082]

Example 2

[0083] It is understood that the non-zero included angle between the first extension segment and the second extension segment means that the first extension segment and the second extension segment extend toward different sides respectively; preferably, they extend in opposite directions, that is, the first extension segment and the second extension segment extend in opposite directions.

[0084] In the embodiments of this application, the included angle between the first extension segment and the second extension segment can be 30°, 45° or 60°, and can be adjusted according to actual needs.

[0085] It is understood that the clamping member is elastic, so when the flip cover 11 is in the open state relative to the box body 14, the clamping member can be in a normal, unpressed state; when the flip cover 11 is closed on the box body 14, the first extension of the clamping member can contact the outer wall 142 of the box body 14 and be pushed by the flip cover 11 to press against the outer wall 142.

[0086] Therefore, based on the above structural form, the sealing of the connection point when the flip cover 11 rotates relative to the box body 14 to open and close the cosmetic powder storage container 100 is achieved by the compression contact between the first extension of the clamping member and the side wall of the box body 14. At the same time, the sealing of the cosmetic powder storage container 100 at the contact surface between the flip cover 11 and the box body 14 is achieved by limiting the airtight member 12 by the second extension and clamping the airtight member 12 between the flip cover 11 and the box body 14. Thus, the overall sealing performance of the cosmetic powder storage container 100 is guaranteed by the synergistic sealing performance of the clamping member and the airtight member 12, effectively preventing the cosmetic powder from getting damp, oxidized and contaminated, and ensuring product quality. Furthermore, when using the cosmetic powder storage container 100, the flip cover 11 only needs to be closed on the box body 14, and the clamping member will automatically compress and contact the side wall to achieve a seal, which improves the convenience of sealing the cosmetic powder storage container 100 during use and provides users with a convenient and hygienic cosmetic use experience.

[0087] One end of the clamping member is a root, which is disposed in the storage groove. A clearance portion is provided between the first extension section and the second extension section. Along the setting direction of the outer side wall 142, the cross-sectional shape of the clamping member is V-shaped.

[0088] It is understood that the V-shape is an inverted V-shape, and the opening of the clamping part is set downwards. The root of the clamping member is fixedly set in the storage groove to stabilize the clamping member.

[0089] In this embodiment, the root of the clamping member is a pointed structure so as to be inserted into the storage slot of the flip cover 11; in other embodiments, the structure of the root of the clamping member 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 storage slot, which is not limited here.

[0090] 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, thereby maximizing the deformation of the clamping element and ultimately maximizing its sealing performance.

[0091] Therefore, based on the above structural form, by setting the clamping element in a V-shape, the elastic extrusion force of the clamping element is improved, making the seal more secure and maintaining good sealing performance even under long-term use.

[0092] In a preferred embodiment, the second extension extends in a direction away from the first extension and protrudes relative to the bottom surface of the flip cover 11. The degree of protrusion can be based on the amount of pressure required to be applied to the airtight member 12.

[0093] By extending the second extension in a direction away from the first extension, the clamping member can effectively apply uniform pressure to the airtight member 12, thereby improving the sealing performance; by designing the second extension to protrude from the bottom surface of the flip cover 11, it is ensured that the airtight member 12 will not shift when under pressure, thereby maintaining a good sealing state.

[0094] In this embodiment of the application, the airtight component 12 has a mesh fabric on the side surface facing the flip cover 11, and the protruding portion of the second extension section can limit the mesh fabric.

[0095] 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.

[0096] Preferably, a gap of 0.05-0.1 mm is provided between the second extension section and the airtight component 12. This setting avoids excessive compression of the airtight component 12 due to an excessively small gap, which would affect its elasticity and sealing effect; while an excessively large gap may lead to poor sealing. Therefore, the gap of 0.05-0.1 mm is optimized to balance pressure and sealing effect.

Example 3

[0098] As a preferred implementation method, such as Figures 16-17 As shown, a slot 145 is provided at the bottom of the outer periphery of the box body 14. There are multiple slots 145, which are arranged in sequence at intervals, preferably three, and are respectively provided on the three sides of the box body 14 excluding the hinge seat 143, so as to realize the replacement function of the cosmetic powder storage container 100, so as to be compatible with the corresponding structure provided on the inner bottom of the outer shell.

[0099] As a preferred implementation method, such as Figures 16-17 As shown, notches 146 are provided at the four top corners of the box body 14. The notches 146 are used to abut against the inner bottom of the outer shell to achieve a stable fit between the box body 14 and the inner bottom, avoiding the introduction of a third component, so as to achieve stable fixation between the box body 14 and the inner bottom.
