[0024] PP: Polypropylene.

[0025] The following is for reference. Figures 1-9 The present invention describes a mesh fabric 111, a mesh base 11, a material box 1, and a cosmetic box 100 according to embodiments of the present invention.

[0026] like Figure 1As shown, the first aspect of this utility model provides a mesh fabric 111, on which a plurality of slit units 112 penetrating its thickness are provided. Each slit unit 112 includes at least two intersecting slits 1121. The slit unit 112 has a closed state that is kept closed by the elastic force of the mesh fabric 111 itself and an open state that is opened under the action of an external force to allow material to pass through. When the external force is removed, the slit unit 112 resets from the open state to the closed state under the action of the elastic force of the mesh fabric 111.

[0027] The materials here can be cosmetic powders such as setting powder, loose powder, and cooling powder.

[0028] It should be further explained that each slit 1121 in the slit unit 112 extends along the thickness direction of the mesh fabric 111. When forming the slit 1121 on the mesh fabric 111, it is necessary to cut through the mesh fabric 111 without removing or removing only a small amount of material. In the static sealing stage, the slit 1121 closes naturally under its own elastic force, forming a barrier to prevent cosmetic leakage. In the dynamic dispensing stage, when pressed down by the powder puff, the mesh fabric 111 deforms, causing the slit 1121 to expand, thereby allowing the cosmetic to be picked up more evenly.

[0029] In a specific application scenario, the mesh 111 can be positioned at the inlet 122 of the material chamber 121, which contains foundation powder. When pressure is applied using tools such as a powder puff, the cutting unit 112 expands with the deformation of the mesh 111, and the degree of expansion of the cutting unit 112 can be controlled by the applied pressure, making the material outflow channel more controllable. After the external force is removed, the cutting unit 112 returns to the closed state under the elastic force of the mesh 111, keeping the cutting 1121 closed and the material sealed in the material chamber 121. At the same time, a powder puff can be placed on the surface of the mesh 111 and seal the cutting 1121, thereby further reducing the possibility of powder leakage when opening and closing the flip cover 3.

[0030] It should be further explained that the cutting unit 112 includes at least two intersecting cuts 1121. Compared with only one cut 1121, it is more convenient to press open and dip, and it helps to reduce powder spraying, especially when dipping the remaining material after use.

[0031] Compared with related technologies, the embodiments provided by this utility model have the following advantages: (1) The sealing and opening functions are achieved through the elastic cut unit 112 of the mesh 111 itself, eliminating the need for the inner cover structure in the traditional solution. This not only simplifies the overall assembly process and reduces the number of parts and cost, but also fundamentally avoids the problem of powder blowing when opening the cover caused by the inner cover and the problem of sealing failure caused by the failure or wear of the inner cover opening and closing mechanism, thus simplifying the operation steps; (2) When pressure is applied using tools such as powder puffs, the cut unit 112 expands as the mesh 111 deforms, and the degree of expansion of the cut unit 112 can be controlled by the amount of pressure applied, providing a more controllable material outflow channel. This design allows materials (such as setting powder, loose powder, and cooling powder) to be picked up more evenly, effectively avoiding the problem of excessive or insufficient powder picking in certain areas caused by traditional open containers or improper openings, thereby helping users achieve a more refined and even makeup effect and improving the user experience; (3) The cutting unit 112 includes at least two intersecting cuts 1121. Compared with only one cut 1121, it is more convenient to press open and pick up the remaining material, especially when there is less residual material. It also helps to reduce the phenomenon of powder spraying.

[0032] like Figure 1 As shown, in some embodiments, the slit unit 112 includes two perpendicular slits 1121. That is, the extension direction of one slit 1121 is perpendicular to the extension direction of the other slit 1121 to form a cross-shaped slit 1121.

[0033] like Figure 1 As shown, furthermore, the two slits 1121 of the slit unit 112 have the same extension length, and the two slits 1121 intersect perpendicularly at the midpoint of their extension length, making the elastic stress distribution of the mesh 111 at the slits 1121 more symmetrical. After the external force is removed, the symmetrical elastic force can drive the four petals of the slit 1121 to reset and close more synchronously and smoothly, reducing the possibility of incomplete closure on one side of the slit 1121 due to uneven stress. This structure can better rely on the elasticity of the mesh 111 itself to return to a tight closed state, forming a more reliable sealing barrier and significantly reducing the risk of leakage and agglomeration of materials when not in use.

[0034] In some embodiments, the extension length of the cut 1121 is 3mm to 4mm. As can be seen from the above embodiments, the two cuts 1121 of the cut unit 112 have the same extension length, and the two cuts 1121 intersect perpendicularly at the midpoint of their extension lengths. The extension length of each cut 1121 of the cut unit 112 is 3mm to 4mm.

[0035] Optionally, the extension length of each cut 1121 in the cut unit 112 is 3mm, 3.2mm, 3.5mm, 3.7mm, 3.9mm, 4mm, etc., and will not be listed here. This spacing range can be adjusted according to the material, thickness, elastic modulus, and expected material outflow of the mesh 111.

[0036] like Figure 1As shown, in some embodiments, multiple slit units 112 are arranged in an array along the extension direction of the slit 1121. Specifically, multiple slit units 112 are arranged sequentially on the mesh fabric 111 at predetermined intervals along the extension direction of the slit 1121, forming a regular arrangement. The multiple slit units 112 arranged in an array along the extension direction of the slit 1121 allow material to seep out evenly over a larger area. When a powder puff or other tool presses the mesh fabric 111, the multiple slit units 112 open simultaneously or in an orderly manner, and the material flows out evenly through multiple channels, avoiding local accumulation or shortage of material caused by single-point material discharge. This results in more even material pick up by the powder puff, which is beneficial for achieving a delicate and smooth makeup effect.

[0037] For example, if the cut 1121 in the cutting unit 112 extends in both the horizontal and vertical directions, multiple cutting units 112 can be arranged sequentially in the horizontal or vertical direction, with a certain spacing between adjacent cutting units 112. This array can be a matrix arrangement with multiple rows and columns, and the arrangement spacing can be set according to actual application requirements to ensure sealing effect while achieving uniform material output.

[0038] like Figure 1 As shown, in some embodiments, the distance between the center points of two adjacent cut units 112 is 1.3mm to 2.5mm. This distance refers to the shortest straight-line distance between the geometric centers of any two adjacent cut units 112 within the plane of the mesh fabric 111. For example, when multiple cut units 112 are arranged in a matrix array, both the lateral and longitudinal spacing can be set within the above range. This spacing range can be adjusted according to the material, thickness, elastic modulus, and expected material outflow of the mesh fabric 111.

[0039] Optionally, the spacing between the center points of two adjacent cut units 112 can be 1.3mm, 1.4mm, 1.5mm, 1.7mm, 1.9mm, 2.0mm, 2.1mm, 2.2mm, 2.4mm, or 2.5mm, and will not be listed here. This spacing range can be adjusted according to the material, thickness, elastic modulus, and expected material outflow of the mesh fabric 111.

[0040] In some embodiments, the mesh 111 is constructed as a thermoplastic elastomer.

[0041] The following is a specific example.

[0042] The mesh fabric 111 is constructed of thermoplastic elastomer, specifically TPE with a tensile strength of 4 MPa to 6.5 MPa, an elongation at break ≥ 550%, and a thickness of 0.4 mm to 0.75 mm. The two slits 1121 of the cutting unit 112 have the same extension length and intersect perpendicularly at the midpoint of their extension length. This increases the elasticity of the mesh fabric 111, solving the problem of a tight feel when pressing to collect powder. It optimizes the problem of easy collapse in conventional mesh fabric 111 and also solves the difficulty in collecting powder. Compared to the technical solution of the cutting unit 112 having only one slit 1121, this solves the problems of easy powder spraying and excessive material residue caused by the cutting unit 112 having only one slit 1121.

[0043] like Figures 1-3 As shown, a second aspect embodiment of the present invention provides a mesh holder 11, which includes a cylindrical structure 113 and a mesh fabric 111 as described in the first aspect embodiment of the present invention. The cylindrical structure 113 has a through-hole cavity 1131; the mesh fabric 111 is connected inside the hollow cavity 1131 of the cylindrical structure 113. A cutting unit 112, in a closed state, blocks material from passing through the hollow cavity 1131, and in an open state, allows material to pass through the hollow cavity 1131.

[0044] The hollow cavity 1131 that is provided through the cylindrical structure 113 here means that the hollow cavity is through the axial direction of the cylindrical structure 113, and the hollow cavity 1131 in the cylindrical structure 113 is connected to both ends of the cylindrical structure 113.

[0045] The cylindrical structure 113 can be installed at the material outlet, which improves the convenience of installation and further simplifies the assembly process of the parts.

[0046] In some embodiments, the cylindrical structure 113 is constructed of PP material, and the cylindrical structure 113 and the mesh fabric 111 are integrally formed by a two-color injection molding process. The mesh base 11 consists of two parts: the cylindrical structure 113 and the mesh fabric 111. It can be integrally formed by methods such as two-color injection molding, which reduces the number of parts and assembly steps, and lowers production costs.

[0047] like Figure 2 , Figure 3 and Figure 4As shown, a third aspect embodiment of the present invention provides a material box 1. In some embodiments, the material box 1 includes a material box body 12 and a mesh base 11 as described in the second aspect embodiment of the present invention. The material box body 12 has a material cavity 121 and a material outlet 122 communicating with the material cavity 121. The mesh base 11 is connected to the material outlet 122 of the material box body 12. The outer circumferential surface of the cylindrical structure 113 is provided with an annular snap fastener 1132 and is interference-fitted to the inner circumferential surface of the material cavity 121. In this embodiment, the cylindrical structure 113 forms an interference fit with the inner circumferential surface of the material cavity 121 through the annular snap fastener 1132, which not only achieves dual axial and radial positioning but also effectively prevents material leakage caused by assembly gaps.

[0048] For example, the annular snap fastener 1132 includes at least two that are spaced apart along the axial direction of the cylindrical structure 113.

[0049] For example, the outer circumferential surface of the cylindrical structure 113 is provided with two annular snap fasteners 1132 spaced apart along the axial direction of the cylindrical structure 113. The annular snap fasteners 1132 form an interference fit with the inner circumferential surface of the material cavity 121, and the interference amount is controlled on one side between 0.1mm and 0.2mm. This interference fit design has a large tolerance range, which can avoid the excessive pressure required when the mesh seat 11 is pressed into the material cavity 121 due to excessive interference, thus facilitating assembly operations; it can also effectively compensate for dimensional deviations caused by different mold processing, ensuring that a reliable seal can still be formed when the mesh seat 11 is cross-fitted with different material box bodies 12, preventing material leakage from the assembly gap in the material cavity 121.

[0050] For example, the cylindrical structure 113 is specifically constructed as a cylinder.

[0051] like Figure 2 , Figures 5-9As shown, a fourth aspect embodiment of the present invention provides a cosmetic box 100. In some embodiments, the cosmetic box 100 includes a base 2, a flip cover 3, a button 4, and a material box 1 according to a third aspect embodiment of the present invention. The base 2 has a receiving cavity 21 and an open opening 22 communicating with the receiving cavity 21. The material box 1 is fixedly connected in the receiving cavity 21, and the outer peripheral surface of the material box 1 is spaced apart from the inner peripheral surface of the receiving cavity 21 to form an installation space 211. The flip cover 3 is hinged to the base 2 and is used to cover the open opening 22. The flip cover 3 is provided with a locking groove 31. The button 4 includes a pressing part 41, a locking part 42, and a resetting part 43. The pressing part 41 is fixedly connected to the locking part 42 and is movably disposed between the locking position and the unlocking position of the installation space 211: In the locking position, the locking part 42 locks with the locking groove 31 to fix the flip cover 3 and the base 2; in the unlocking position, the locking part 42 exits the locking groove 31 to allow the flip cover 3 to rotate relative to the base 2; wherein, the reset part 43 is constructed as an arc-shaped spring piece, the reset part 43 is disposed in the installation space 211, one end of the reset part 43 is connected to the pressing part 41 in the arc-shaped extension direction and the other end of the reset part 43 abuts against the outer peripheral surface of the material box 1 to drive the pressing part 41 to reset from the unlocking position to the locking position.

[0052] See Figure 5 The reset part 43 is constructed as an arc-shaped spring, which facilitates the arrangement of operating components within the limited installation space 211, effectively reducing the overall space occupied by the button 4, making the overall structure of the cosmetic box 100 more compact, and meeting the market demand for small and portable products. At the same time, the elasticity of the arc-shaped spring can effectively reduce the required pressing force, improve the operating feel, and avoid affecting the user experience due to excessive pressing force.

[0053] In practical implementation, the thickness of the arc-shaped spring reset part 43 can be set to 0.5mm~0.7mm, and the pressing deformation stroke is controlled within the range of 1.2mm~2mm. This parameter range can ensure sufficient elastic restoring force while allowing the flip cover 3 to pop open naturally after unlocking, and the pressing process is smooth and comfortable, further improving the product's ease of use and user experience.

[0054] In summary, the curved button 4 not only solves the problems of large space occupation and high pressing force of traditional button 4, but also meets the market demand for compact, portable, transparent or semi-transparent appearance design.

[0055] like Figure 5 , Figure 6 , Figure 7As shown, furthermore, the installation space 211 is also provided with a partition 2111, and the partition 2111 is symmetrically provided with limiting grooves 2112; the button 4 is also provided with a limiting part 44, which extends in a direction perpendicular to the pressing part 41. The limiting part 44 includes two symmetrically arranged on both sides of the arc-shaped spring axial direction. The size of the limiting part 44 is larger than the size of the limiting groove 2112 to limit the arc-shaped spring in the installation space 211. The limiting part 44 is constructed as a limiting buckle, and the limiting buckle is interference-fitted with the limiting groove 2112. The limiting buckle interference is 0.45mm on one side, which ensures that the force is not too large when the button 4 is installed to avoid deformation, and also ensures that the button 4 is not easy to separate after assembly. The anti-shake gap in the four directions of up, down, left and right is within the range of 0.1-0.25mm, which ensures that the button 4 is pressed smoothly and that the movement gap of the button 4 is not too large, which would affect the product quality.

[0056] For example, the flip cover 3 also features a glass lens.

[0057] Other configurations and operations of the cosmetic box 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
