Description

Technical Field

[0001] This application relates to the field of cosmetic technology, and more particularly to a loose powder box and cosmetic set. Background Technology

[0002] Most of the loose powder boxed products in related technologies are not replaceable structures, mainly because the products are prone to powder leakage and powder scattering when the lid is opened or closed. These problems make it difficult to develop replacement packaging materials. Utility Model Content

[0003] This application proposes a loose powder box to effectively solve the technical problems of powder leakage and powder scattering when opening and closing the lid in related technologies.

[0004] This application also proposes a cosmetic set including the aforementioned loose powder box.

[0005] A first aspect of this application provides a loose powder box, including: a box body, an outer cover assembly, and an inner cover;

[0006] The box is equipped with an inner liner.

[0007] The inner cover is disposed on the box body and is used to open and close the inner liner; a sealing element for sealing is provided between the inner cover and the inner liner.

[0008] The outer cover assembly is closably disposed on the housing and is used to act on the inner cover when closed, so that the outer cover assembly can provide a force to press the seal.

[0009] Furthermore, the seal is disposed on the inner cover, the seal includes a sealing bevel for contacting the inner liner, and the inner liner includes a first protruding structure for contacting the seal, the first protruding structure being used to press and seal against the sealing bevel.

[0010] Furthermore, the inner liner includes a first side located on the inner side and adjacent to the first protruding structure, and the seal includes a second side located on the inner side and adjacent to the sealing slope, with an open space between the first side and the second side.

[0011] Furthermore, the outer cover assembly is provided with a second protrusion structure, which is used to press the inner cover together when the outer cover assembly is closed.

[0012] Furthermore, the outer cover assembly includes an upper outer cover and a lower outer cover. The lower outer cover is hinged to the box body, and the upper outer cover is disposed on the lower outer cover and used to cooperate with the box body, so that the lower outer cover can be positioned by cooperating with the box body through the upper outer cover when closed.

[0013] Furthermore, the box body is provided with a first screw fastening tooth structure, and the upper outer cover is provided with a second screw fastening tooth structure that cooperates with the first screw fastening tooth structure. The upper outer cover is rotatably mounted on the lower outer cover relative to the lower outer cover. When the lower outer cover is closed, the upper outer cover can rotate to make the first screw fastening tooth structure cooperate with the second screw fastening tooth structure to limit the position of the lower outer cover, or to make the first screw fastening tooth structure and the second screw fastening tooth structure misaligned to release the position limitation on the lower outer cover.

[0014] Furthermore, the inner liner is detachably mounted inside the box via a snap-fit ​​structure.

[0015] Furthermore, the inner liner and the box body also have a limiting inclined surface and an interference structure. When the inner liner is set in the box body by the snap-fit ​​structure, the interference structure and the limiting inclined surface are interference-fitted and used to limit the inner liner in the horizontal direction.

[0016] Furthermore, a limiting ring is provided between the inner liner and the box body. The limiting ring is provided in a spaced manner with the interference structure and is used to limit the inner liner in the vertical direction.

[0017] As can be seen from the above technical solutions, the embodiments of this application have at least the following beneficial effects: based on the use of sealing elements to seal the inner liner, the outer cover assembly can press the inner cover to form a more effective seal by cooperating with the inner cover and outer cover assembly, which solves problems such as product powder leakage and powder scattering when opening and closing the cover, and provides a basis for the replacement of the inner liner.

[0018] A second aspect of this application provides a cosmetic kit, including a loose powder box as described in the first aspect of this application.

[0019] It is easy to understand that the cosmetic set in the second aspect embodiment of this application has the same technical effect as the loose powder box in the first aspect embodiment, and therefore will not be described again.

[0020] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0032] 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 skilled in the art without creative effort are within the scope of protection of this application.

[0033] See Figures 1 to 4 As shown, an embodiment of the first aspect of this application discloses a loose powder box, including a box body 100, an outer cover assembly 300, and an inner cover 400.

[0034] The box body 100 is provided with an inner liner 200; an inner cover 400 is provided on the box body 100 and is used to open and close the inner liner 200, and a sealing element 410 is provided between the inner cover 400 and the inner liner 200 for sealing; an outer cover assembly 300 is provided on the box body 100 in an openable and closable manner, and the outer cover assembly 300 is used to act on the inner cover 400 when closed, so that the outer cover assembly 300 can provide a force to press the sealing element 410.

[0035] In the embodiments of this application, based on the sealing of the inner liner 200 by the sealing element 410, the inner cover 400 and the outer cover assembly 300 are configured in cooperation. The outer cover assembly 300 can press the inner cover 400 to form a more effective seal, which solves the problems of product powder leakage and powder scattering when opening and closing the cover, and provides a basis for the replacement of the inner liner 200.

[0036] Understandably, in some embodiments, a cavity is formed inside the box body 100 for the installation of the inner liner 200. The inner liner 200 is disposed in the cavity in a detachable or non-detachable manner. The inner cover 400 and the outer cover assembly 300 are respectively movably disposed on the box body 100. When the loose powder stored in the inner liner 200 is to be used, the outer cover assembly 300 is opened first, and then the inner cover 400 is opened. Since the entire opening process is divided into two steps, it is not easy for powder to be scattered when opening and closing the cover. At the same time, when the inner liner 200 is to be sealed after use, the inner cover 400 is closed first, and then the outer cover assembly 300 is closed. After the outer cover assembly 300 is closed, it can act on the inner cover 400. The inner cover 400 is pressed, so that the sealing element 410 disposed between the inner cover 400 and the inner liner 200 is also subjected to force simultaneously, thereby improving the sealing effect of the sealing element 410 and solving the problem of product powder leakage. Based on the above structure, even if the inner liner 200 is designed to be detachable and replaceable and is set in the cavity, the problems of powder leakage and powder scattering when opening and closing the cover can be solved by the cooperation of the inner cover 400 and the outer cover assembly 300, thereby providing a basis for the replacement of the inner liner 200.

[0037] It should be understood that the sealing element 410 of this application can improve the sealing effect by applying pressure to the end face. In some embodiments, the sealing element 410 is a commonly used flexible sealing element 410 such as an O-ring, a combination sealing gasket, or a flat gasket.

[0038] The following will combine Figures 1 to 4 The powder box disclosed in the embodiments of this application will be explained and described in detail.

[0039] In some embodiments of this application, such as Figure 2 A sealing element 410 is disposed on the inner cover 400. The sealing element 410 includes a sealing bevel 411 for contacting the inner liner 200. The inner liner 200 includes a first protruding structure 210 for contacting the sealing element 410, and the first protruding structure 210 is used to press and seal against the sealing bevel 411. It can be understood that, in order to further improve the sealing effect between the inner liner 200 and the inner cover 400, it can be achieved not only by designing the structure of the sealing element 410, but also by further designing the structure that directly contacts the sealing element 410 and achieves the sealing effect.

[0040] To address this, in addition to the sealing element 410 being mounted on the inner cover 400, a first protruding structure 210 is provided on the inner liner 200. This first protruding structure 210 directly contacts the sealing element 410, ensuring the machining accuracy of the first protruding structure 210 to achieve the required sealing performance with low dimensional accuracy requirements, thus guaranteeing the sealing effect. Simultaneously, by defining the sealing end face of the sealing element 410 as an inclined surface, the sealing effect is more stable due to the pressure exerted on the inner cover 400 by the pressure from the inclined sealing surface 411 and the top pressure of the first protruding structure 210. Furthermore, the clamping force on the sealing element 410, combined with the inclined sealing surface 411, allows for better cooperation with the first protruding structure 210 to form a more effective seal, resulting in a more stable opening feel and reducing the likelihood of dust generation during opening and closing.

[0041] In other embodiments, the seal 410 is disposed on the inner liner 200, and the inner cover 400 is provided with the first protrusion structure 210 as described above, which can achieve a similar effect, and will not be described in further detail.

[0042] Furthermore, to ensure a comfortable feel when opening the lid and to minimize the amount of powder that may be blown out, continue to refer to... Figure 2 The inner liner 200 includes a first side 211 located on the inner side and adjacent to the first protrusion structure 210, and the sealing member 410 includes a second side 412 located on the inner side and adjacent to the sealing slope 411. There is a clearance space 500 between the first side 211 and the second side 412.

[0043] Understandably, the inner liner 200 has an opening for loose powder to enter and exit. The first protruding structure 210 is arranged around the opening so that it can cooperate with the sealing element 410, allowing the opening to be closed by the inner cover 400. The first side 211 is located on the side of the first protruding structure 210 that is relatively closer to the opening, and the corresponding second side 412 is also relatively closer to the opening. By limiting the gap between the first side 211 and the second side 412 and leaving a clearance space 500, when opening and closing the cover, this clearance space 500 can not only be used as a deformation range for the plastic deformation of the inner cover 400 and the inner liner 200, improving the feel of opening the cover, but also can be used as a buffer space for loose powder to fly, achieving the effect of not easily causing powder to fly when opening the cover.

[0044] In some embodiments, the clearance between the first side 211 and the second side 412 is about 0.25~0.45mm. By limiting the size of the clearance space 500, the dimensional tolerance at the mating point of the inner liner 200 and the seal 410 is improved, further ensuring a comfortable opening feel and preventing dust from being stirred up when opening and closing the lid.

[0045] In some embodiments of this application, the outer cover assembly 300 is provided with a second protruding structure 330, which is used to press the inner cover 400 when the outer cover assembly 300 is closed. It is understood that the second protruding structure 330 presses the inner cover 400 so that the sealing element 410 on the inner cover 400 presses against the first protruding structure 210 of the inner liner 200, forming an effective seal and further solving the powder leakage problem.

[0046] In some embodiments, the second protrusion structure 330 includes at least two protrusions spaced apart, the protrusions protruding from the bottom surface of the outer cover assembly 300 toward the inner cover 400 at a predetermined height, so that when the outer cover assembly 300 is engaged with the box body 100 and closed, the protrusions can press the inner cover 400 to ensure no powder leakage.

[0047] In some embodiments, the shape of the second protrusion structure 330 may be configured to include, but is not limited to, commonly used geometric structures or irregular structures such as columnar protrusions, blocky protrusions, curved protrusions or prismatic protrusions.

[0048] In some embodiments of this application, reference is made to Figure 1 and Figure 4 The outer cover assembly 300 includes an upper outer cover 310 and a lower outer cover 320. The lower outer cover 320 is hinged to the box body 100. The upper outer cover 310 is disposed on the lower outer cover 320 and is used to cooperate with the box body 100 so that the lower outer cover 320 can be positioned by cooperating with the box body 100 through the upper outer cover 310 when closed.

[0049] Understandably, the lower outer cover 320 is hinged to the box body 100 and serves to open and close the inner liner 200. The sealing element 410 is located on the bottom surface of the lower outer cover 320. The upper outer cover 310 is located on the lower outer cover 320 and moves synchronously with the opening and closing of the lower outer cover 320. When the lower outer cover 320 is closed, the upper outer cover 310 is also in the closed position and can cooperate with the box body 100, achieving a switch between locked and unlocked states through cooperation with the box body 100. Specifically, when it is necessary to close the opening of the inner liner 200, the lower outer cover 320 is closed, and the upper outer cover 310 cooperates with the box body 100 to lock, thereby fixing the outer cover assembly 300 to the box body 100; when it is necessary to open the opening of the inner liner 200, the upper outer cover 310 is unlocked from the box body 100, and the outer cover assembly 300 can be opened from the box body 100 for normal use of loose powder.

[0050] In some embodiments, the outer cover 310 and the box body 100 are engaged by, but not limited to, snap-fit, threaded connection, magnetic connection, and pin connection.

[0051] Furthermore, referring to Figure 4The box body 100 is provided with a first screw fastening tooth structure 130, and the upper outer cover 310 is provided with a second screw fastening tooth structure 311 that cooperates with the first screw fastening tooth structure 130. The upper outer cover 310 is rotatably mounted on the lower outer cover 320 relative to the lower outer cover 320. When the lower outer cover 320 is closed, the upper outer cover 310 can rotate to make the first screw fastening tooth structure 130 cooperate with the second screw fastening tooth structure 311 to limit the position of the lower outer cover 320, or make the first screw fastening tooth structure 130 and the second screw fastening tooth structure 311 misaligned to release the position limitation of the lower outer cover 320. It is understandable that the upper outer cover 310 can rotate relative to the lower outer cover 320. After the lower outer cover 320 is in the closed position, the upper outer cover 310 can be rotated to adjust to the appropriate position. When the first swivel tooth structure 130 and the second swivel tooth structure 311 are aligned, the outer cover assembly 300 is locked to the box body 100. When the first swivel tooth structure 130 and the second swivel tooth structure 311 are misaligned, the outer cover assembly 300 is unlocked from the box body 100, achieving the effect of convenient opening and closing and preventing powder leakage.

[0052] In some embodiments, the first snap tooth structure 130 includes a plurality of first snap teeth spaced apart circumferentially along the box body 100, and the second snap tooth structure 311 includes a plurality of second snap teeth spaced apart circumferentially along the upper outer cover 310. When at least some of the first snap teeth are aligned with the second snap teeth, the outer cover assembly 300 is locked to the box body 100. When the first snap teeth are misaligned with the second snap teeth, the outer cover assembly 300 is unlocked from the box body 100.

[0053] In some embodiments of this application, reference is made to Figure 4 The inner liner 200 is detachably installed inside the box body 100 via a snap-fit ​​structure. It is understandable that, given the detachable installation of the inner liner 200 within the box body 100, the snap-fit ​​structure enhances the ease of assembly and disassembly, making it convenient for users to replace the liner.

[0054] In one specific embodiment, refer to Figure 4 The snap-fit ​​structure includes a snap groove 220 and a snap foot 110; the snap groove 220 and the snap foot 110 are respectively provided on the inner liner 200 and the box body 100, and the inner liner 200 is installed in the box body 100 by the snap foot 110 cooperating with the snap groove 220.

[0055] In other embodiments, the buckle groove 220 and the buckle foot 110 are respectively provided on the box body 100 and the inner liner 200. The inner liner 200 is installed in the box body 100 by the buckle foot 110 cooperating with the buckle groove 220, which can achieve the same similar effect as described above.

[0056] In other embodiments, the inner liner 200 is installed inside the box body 100 by means of tenon and mortise connection, threaded connection, pin connection, buckle connection, etc., which can achieve similar effects to the above-mentioned detachable connection.

[0057] It is understandable that, in order to ensure higher positional accuracy of the detachable inner liner 200 after installation, some embodiments of this application, such as... Figure 3 The inner liner 200 and the box body 100 also have a limiting inclined surface 212 and an interference structure 120. When the inner liner 200 is set in the box body 100 by the snap-fit ​​structure, the interference structure 120 is in interference fit with the limiting inclined surface 212 and is used to limit the inner liner 200 in the horizontal direction.

[0058] It is understandable that the limiting slope 212 and the interference fit structure 120 can be interference-fitted after the inner liner 200 is snapped onto the box body 100. The limiting slope 212 and the interference fit structure 120 can increase the dimensional tolerance of the inner liner 200 and the box body 100, and prevent the inner liner 200 from shaking vertically and horizontally.

[0059] In some embodiments, the interference fit between the interference structure 120 and the limiting inclined surface 212 is about 0.05~0.1mm. Under this size limitation, the dimensional tolerance can be further increased, and the effect of upper limit positioning of the inner liner 200 in the vertical and horizontal directions can be improved.

[0060] Furthermore, continue to refer to Figure 3 A limiting ring 213 is also provided between the inner liner 200 and the box body 100. The limiting ring 213 is arranged in a spaced manner with the interference structure 120 and is used to limit the inner liner 200 in the vertical direction. It can be understood that the limiting ring 213 and the interference structure 120 are arranged in a spaced manner and cooperate with each other vertically. By limiting the inner liner 200 vertically at the connection between the inner liner 200 and the box body 100, the inner liner 200 will not move vertically.

[0061] In some embodiments, the width of the limiting ring 213 is 0.2~0.35mm and the height is 0.1~0.2mm. Under this size limitation, the size tolerance can be further increased, and the effect of limiting the upper and lower directions of the inner liner 200 can be improved.

[0062] The powder box of this application is described in detail below with a specific embodiment. It should be noted that the following embodiment is merely an exemplary description and should not be construed as limiting the embodiments of this application.

[0063] See Figures 1 to 4As shown, the loose powder box in this embodiment is used for loose powder products, such as setting powder, loose powder, and cooling powder. The loose powder box includes an outer cover assembly 300, an inner cover 400, an inner liner 200, and a box body 100. The outer cover assembly 300 is a rotating flip-top, composed of an upper outer cover 310 and a lower outer cover 320, which can rotate relative to each other by 20-40°. The upper outer cover 310 has a locking tooth that engages with the locking tooth of the box body 100. The lower outer cover 320 has a sealing pressure point; when the upper outer cover 310 is rotated to its final position, it presses against the inner cover 400, thereby ensuring that the opening of the inner liner 200 does not leak powder.

[0064] Specifically, the inner cover 400 is equipped with a sealing ring made of thermoplastic elastomer (TPE) or thermoplastic polyurethane (TPU), which is integrally molded with the inner cover 400 made of materials such as PP (Polypropylene) or HDPE (High-Density Polyethylene) through a two-color injection molding process. The pressure point of the lower outer cover 320 is used to press the inner cover 400 tightly, so that the sealing ring on the inner cover 400 presses against the opening edge of the inner liner 200, forming an effective seal and solving the powder leakage problem.

[0065] Meanwhile, the first protruding structure 210 of the inner liner 200 opening and the inclined sealing ring of the inner cover 400 are sealed by top pressure, which not only has low requirements for dimensional accuracy but also provides a more stable sealing effect, a more stable opening feel, and reduces the likelihood of dust scattering when opening and closing the cover. In addition, the side of the inner liner 200 opening and the side of the inner cover 400 sealing ring are spaced apart by about 0.25~0.45mm, improving dimensional tolerance, ensuring a comfortable opening feel, and reducing the likelihood of dust scattering when opening and closing the cover.

[0066] Furthermore, the inner liner 200 is provided with a snap groove 220, and the box body 100 is provided with snap feet 110. By pressing down from top to bottom, the snap groove 220 of the inner liner 200 mates with the snap feet 110 of the box body 100, allowing the inner liner 200 to be inserted. The snap groove 220 and snap feet 110 facilitate assembly and disassembly. To prevent the inner liner 200 from shifting, a limiting ring 213 and a limiting inclined surface 212 are provided to limit the snap-fit ​​connection of the inner liner 200. Specifically, the limiting ring 213 (width: 0.2~0.35mm; height: 0.1~0.2mm) works in conjunction with the limiting inclined surface 212 to prevent the inner liner 200 from shifting vertically. The limiting inclined surface 212 interference mechanism (interference amount of about 0.05~0.1mm) includes the limiting inclined surface 212 and the interference structure 120. The limiting inclined surface 212 and the interference structure 120 are interference-fitted to increase dimensional tolerance and prevent the inner liner 200 from shaking in the vertical and horizontal directions.

[0067] The above-described design allows for easy replacement of the inner liner 200 in the powder box, simplifying the operation and achieving the environmentally friendly goal of reusing the outer shell. The use of a first protruding structure 210 and a sloped top-pressing sealing method ensures better sealing, reduces requirements on packaging molds and molding precision, and is more conducive to stable mass production quality. Simultaneously, the side of the inner cover 400 and the side of the inner liner 200 are not intersected, improving dimensional tolerance, ensuring a comfortable opening feel, and minimizing powder spillage during opening and closing.

[0068] The second aspect of this application discloses a cosmetic kit, including: a loose powder box according to the first aspect of this application.

[0069] It is easy to understand that the cosmetic set in the second aspect embodiment of this application has the same technical effect as the loose powder box in the first aspect embodiment, and therefore will not be described again.
