[0056] The cosmetic substance loading device of this application embodiment is used to load cosmetic substances. The cosmetic substances are contained in the cosmetic substance loading device for easy carrying and use. The cosmetic substances can be liquid cosmetic substances, such as: foundation, concealer, eyeshadow, eyeliner, mascara, lipstick, blush, etc.

[0057] The following combination Figures 1-13 The cosmetic substance loading device 100 according to an embodiment of this application will be described below.

[0058] See Figures 1-5 In some embodiments, the cosmetic substance loading device 100 includes a housing 10, a material-permeable member 20, and a sealing member 50. The housing 10 has a receiving cavity 1001 and a first opening 1021 and a second opening 1011 communicating with the receiving cavity 1001. The first opening 1021 and the second opening 1011 are located at opposite ends of the housing 10. The receiving cavity 1001 is used to load cosmetic substances. At least a portion of the material-permeable member 20 is located within the receiving cavity 1001. The material-permeable member 20 covers the first opening 1021 and is exposed through the first opening 1021. The material-permeable member 20 is used to allow cosmetic substances to pass through. The sealing member 50 is connected to the housing 10 and seals the second opening 1011.

[0059] The shell 10 refers to a hollow component, which can be formed independently by a single component or by splicing together multiple components; its material can be metal, plastic, etc., and its shape can be cylinder, prism, etc.

[0060] The internal cavity of the housing 10 forms a receiving cavity 1001, which is used to receive cosmetic material and the transparent part 20. The two ends of the housing 10 are respectively provided with a first opening 1021 and a second opening 1011. The first opening 1021 provides a channel for the exposure of the transparent part 20 and the application of cosmetic material, and the second opening 1011 is sealed by the sealing member 50 to form a closed structure.

[0061] For example, the shell 10 is a hollow cylindrical structure with openings at both ends.

[0062] The permeable part 20 refers to a component that allows cosmetic substances to pass through. It may have a porous structure to absorb cosmetic substances, and its material may be a sponge or the like. The permeable part 20 covers the first opening 1021 so that the cosmetic substances will not flow directly out of the first opening 1021, but the permeable part 20 itself needs to allow the cosmetic substances to pass through so that the user can easily pick them up.

[0063] In some examples, the transparent element 20 may be partially or entirely located within the receiving cavity 1001; the first opening 1021 allows the transparent element 20 to be exposed outside the housing 10. The transparent element 20 may extend outside the housing 10 through the first opening 1021 or may not extend outside the first opening 1021. The transparent element 20 is exposed through the first opening 1021, allowing the user to squeeze the transparent element 20 through the first opening 1021 to pick up the cosmetic substance on the transparent element 20.

[0064] The permeable part 20 can refer to a component that allows cosmetic substances to pass through. The permeable part 20 may have a porous structure to absorb cosmetic substances. The material of the permeable part 20 may be a sponge or the like. The permeable part 20 covers the first opening 1021 so that the cosmetic substances do not flow directly out of the first opening 1021, but the permeable part 20 itself needs to allow the cosmetic substances to pass through so that the user can easily pick them up.

[0065] In some examples, the transparent element 20 may be partially or entirely located within the receiving cavity 1001. The first opening 1021 allows the transparent element 20 to be exposed outside the housing 10. The transparent element 20 may extend outside the housing 10 through the first opening 1021 or may not extend outside the first opening 1021. The transparent element 20 is exposed through the first opening 1021, allowing the user to squeeze the transparent element 20 through the first opening 1021 to pick up the cosmetic substance on the transparent element 20.

[0066] The sealing element 50 refers to the component that seals the second opening 1011, and can close the second opening 1011 and be sealed to the housing 10; for example, the sealing element 50 and the housing 10 can be sealed to each other by means of heat fusion, sealing ring, elastic sealing contact, etc. The sealing element 50 can be a component such as a sealing membrane 51.

[0067] By adopting the technical solution of this embodiment, the first opening 1021 is covered by the material-permeable part 20, and the second opening 1011 is sealed by the sealing part 50. At this time, the cosmetic substance in the receiving cavity 1001 is in a near-closed environment. The closed environment can reduce the flow of cosmetic substance due to gravity. Even if the material-permeable part 20 is facing down, the cosmetic substance is not easy to leak from the material-permeable part 20, reducing the situation of contaminating surrounding items and waste, and improving the reliability and user experience of the cosmetic substance loading device 100.

[0068] In some embodiments, the seal 50 is a sealing film 51.

[0069] The sealing film 51 refers to a sheet material that is thin, flexible and deformable and can achieve gas and liquid barrier; the sealing film 51 can be polyethylene terephthalate film, polyethylene film, thermoplastic elastomer film, etc.

[0070] By adopting the technical solution of this embodiment, the second opening 1011 is sealed by the sealing film 51, and the sealing operation is simple and the sealing effect is good.

[0071] In some embodiments, the sealing film 51 includes a sealing portion 511 and a connecting portion 512 connected to the periphery of the sealing portion 511. The sealing portion 511 covers the second opening 1011, and the connecting portion 512 is sealed to the housing 10.

[0072] The sealing part 511 can refer to the part of the sealing film 51 that covers the second opening 1011, and the connecting part 512 can refer to the part of the sealing film 51 that is sealed and connected to the housing 10. The connecting part 512 can be sealed and connected to the housing 10 by clamping, bonding or pressing.

[0073] By adopting the technical solution of this embodiment, the connecting part 512 at the edge of the sealing film 51 is sealed and fixedly connected to the housing 10. The fixing method is simple, the fixing reliability is good, and it is beneficial to improve the sealing performance.

[0074] In some embodiments, the area of ​​the sealing portion 511 is larger than the area of ​​the second opening 1011.

[0075] The area of ​​the sealing portion 511 is larger than the area of ​​the second opening 1011, allowing the sealing portion 511 to protrude either towards or away from the receiving cavity 1001. When the material-transmitting part 20 is facing downwards, the middle of the sealing portion 511 has a lowest point, and the middle of the sealing portion 511 droops towards the first opening 1021. When the middle of the sealing portion 511 can no longer fall, the middle of the sealing portion 511 is at its lowest point. When loading cosmetic material into the receiving cavity 1001, it can be filled only to the lowest point of the middle of the sealing portion 511, filling the space between the sealing portion 511 and the material-permeable member 20. This prevents the cosmetic material from flowing out when the first opening 1021 faces downwards. The middle of the sealing portion 511 has already reached its lowest point, and the sealing portion 511 is fixed to the housing 10 via the connecting portion 512, preventing it from moving. Simultaneously, the sealing film 51 is airtight, preventing air from entering the receiving cavity 1001 through the second opening 1011, thus making the receiving cavity 1001 relatively closed. When the first opening 1021 faces downwards, the cosmetic material in the material-permeable member 20 and the receiving cavity 1001 is relatively viscous, and combined with the sealing effect of the sealing portion 511, it makes it difficult for the cosmetic material to flow out from the first opening 1021.

[0076] After the cosmetic substance inside the perforating element 20 is squeezed out, the perforating element 20 adsorbs the cosmetic substance from the receiving cavity 1001. Under atmospheric pressure, regardless of the direction the first opening 1021 faces, air will enter the receiving cavity 1001 through the perforating element 20. When the perforating element 20 is facing downwards, because the cosmetic substance is heavier than air, it flows towards the lower perforating element 20, and air enters the upper side of the receiving cavity 1001, forming an air-filled cavity on the upper side of the receiving cavity 1001. If the ambient temperature rises from a low temperature to a high temperature, the air in the cavity will expand due to heat, and the sealing part 511 will bulge outwards from the receiving cavity 1001 under the action of internal air pressure. This outward expansion releases excess pressure in the receiving cavity 1001, reducing the possibility of cosmetic substance leaking out of the perforating element 20 due to excessive internal air pressure, thus lowering the risk of leakage. If the ambient temperature drops from high temperature to low temperature, the sealing part 511 will bulge towards the receiving cavity 1001 under the action of internal air pressure, thereby relieving the air pressure in the receiving cavity 1001. This can effectively improve the problem of cosmetic leakage caused by temperature changes. At the same time, under the sealing effect of the sealing film 51, the cosmetic will not leak from the material-permeable part 20.

[0077] In some embodiments, the cosmetic substance loading device 100 further includes an end cap 60, which is disposed over the second opening 1011 and covers the sealing portion 511. The end wall of the end cap 60 opposite to the second opening 1011 is spaced apart from the second opening 1011.

[0078] End cap 60 refers to a component that covers the second opening 1011. End cap 60 can be made of various materials, such as plastic or metal. The shape of end cap 60 is adapted to the shape of the second opening 1011 so as to completely cover the second opening 1011. For example, end cap 60 can be a cylindrical structure with one end open.

[0079] End cap 60 covers sealing portion 511. The end wall of end cap 60 opposite to second opening 1011 is spaced apart from second opening 1011, creating a space between end cap 60 and second opening 1011. This space provides room for sealing portion 511 to protrude away from receiving cavity 1001, reducing the risk of cosmetic material leakage from material permeable part 20 due to excessive internal air pressure. Simultaneously, end cap 60 also shields sealing portion 511, reducing the risk of damage to sealing portion 511.

[0080] In some embodiments, the end cap 60 is provided with a vent 61 for communicating with the outside and the inner cavity of the end cap 60.

[0081] The vent 61 is used to connect the external atmosphere and the inner cavity of the end cap 60. The vent 61 can be located on the side wall or the top wall of the end cap 60. There can be one or more vents 61, and the shape of the vent 61 can be various, such as round or square.

[0082] By adopting the technical solution of this embodiment, the vent 61 can balance the air pressure inside and outside the end cap 60, so as to facilitate the sealing part 511 to protrude into or out of the receiving cavity 1001.

[0083] In some embodiments, the connecting portion 512 is clamped between the end cap 60 and the housing 10.

[0084] The connecting portion 512 is clamped between the inner peripheral wall of the end cap 60 and the outer peripheral wall of the housing 10; or, the connecting portion 512 is clamped between the end wall of the end cap 60 opposite to the second opening 1011 and the end face of the housing 10 where the second opening 1011 is provided; or, a part of the connecting portion 512 is clamped between the inner peripheral wall of the end cap 60 and the outer peripheral wall of the housing 10, and another part of the connecting portion 512 is clamped between the end wall of the end cap 60 opposite to the second opening 1011 and the end face of the housing 10 where the second opening 1011 is provided.

[0085] In some examples, after the sealing film 51 covers the second opening 1011, the periphery of the sealing film 51 protrudes out of the outer side of the housing 10, and then the end cap 60 is fitted onto the end of the housing 10. At this time, the edge of the sealing film 51 is sandwiched between the inner peripheral wall of the end cap 60 and the outer peripheral wall of the housing 10, that is, the connecting part 512 is sandwiched between the inner peripheral wall of the end cap 60 and the outer peripheral wall of the housing 10, and the part of the sealing film 51 that directly covers the second opening 1011 is the sealing part 511.

[0086] By adopting the technical solution of this embodiment, the connecting part 512 is tightly clamped between the end cap 60 and the housing 10. This fixing method can achieve the sealing and fixing of the sealing element 50 without the use of other fixing parts, which is beneficial to reducing manufacturing costs. In addition, the connecting part 512 at the edge of the sealing film 51 is clamped and fixed, which does not restrict the deformation space of the sealing part 511 opposite to the second opening 1011 in the sealing film 51. This allows the sealing part 511 to freely protrude into or out of the receiving cavity 1001 when the air pressure changes. This can achieve the air pressure balance function and ensure that the sealing performance of the sealing element 50 is not damaged after deformation through the stable fixing of the connecting part 512.

[0087] In some embodiments, the thickness of the sealing film 51 ranges from 0.01 mm to 1 mm.

[0088] It is understood that the thickness h of the sealing film 51 can be 0.01 mm, 1 mm, or any value between 0.01 mm and 1 mm. For example, the thickness h of the sealing film 51 can be 0.01 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.7 mm, 0.9 mm, or 1 mm.

[0089] By adopting the technical solution of this embodiment, the thickness h of the sealing film 51 is set to the above range, so that the sealing film 51 has good deformation ability, can adapt to the air pressure changes in the accommodating cavity 1001, and the sealing film 51 has good structural strength, thereby improving the stability of the seal.

[0090] In some embodiments, the sealing film 51 is a polyethylene terephthalate (PET) film, a polyethylene (PE) film, a thermoplastic elastomer (TPE) film, an ethylene (PE) film, a polyvinyl chloride (PVC) film, a polyvinylidene chloride (PVDC) film, or a polypropylene (PP) film.

[0091] By adopting the technical solution of this embodiment, the sealing film 51 is a film made of the above-mentioned material, which makes the sealing film 51 have better sealing performance, and the sealing film 51 can also freely bulge or dent as the air pressure of the receiving cavity 1001 changes.

[0092] Please refer to the following: Figures 6-8 In some embodiments, the receiving cavity 1001 has a first sub-region 101 and a second sub-region 102 that are connected to each other. The first sub-region 101 is used to load cosmetic substances. A second opening 1011 is connected to the first sub-region 101 and is located on the side of the first sub-region 101 facing away from the second sub-region 102. A first opening 1021 is connected to the second sub-region 102 and is located on the side of the second sub-region 102 facing away from the first sub-region 101. At least a portion of the material-transmitting member 20 is located in the second sub-region 102, and the first sub-region 101 is not provided with the material-transmitting member 20. The material-transmitting member 20 is elastic and can automatically recover after being deformed by compression, thereby drawing the cosmetic substances in the first sub-region 101 into the material-transmitting member 20.

[0093] The receiving cavity 1001 can be divided into two parts, one part being a first sub-region 101 and the other part being a second sub-region 102. The first sub-region 101 and the second sub-region 102 can form a cavity or be two independent and connected cavities. The first sub-region 101 is used to load cosmetic substances, and the second sub-region 102 provides installation space for the material-transparent component 20, which does not extend into the first sub-region 101.

[0094] The material-permeable part 20 is elastic and can be deformed under external force. After the external force is removed, the material-permeable part 20 can automatically return to its original shape.

[0095] By adopting the technical solution of this embodiment, during the use of the cosmetic substance loading device 100, the user presses the transparent part 20 through the first opening 1021 to pick up the cosmetic substance on the transparent part 20. When the user removes the pressing pressure, the transparent part 20 can automatically return to its original state. During the automatic return process, the transparent part 20 can also absorb the cosmetic substance in the first sub-area 101 into the transparent part 20, thereby realizing the replenishment of the transparent part 20. The cosmetic substance loading device 100 of this application embodiment uses a first sub-region 101 to store cosmetic substances. At least a portion of the transparent element 20 is located in a second sub-region 102, and the transparent element 20 does not extend into the first sub-region 101, thus separating the area storing cosmetic substances from the transparent element 20. At the same time, during use, the cosmetic substances in the first sub-region 101 can also be adsorbed onto the transparent element 20 and used. Most or all of the cosmetic substances in the first sub-region 101 can be replenished onto the transparent element 20 and used by the user. Therefore, most of the cosmetic substances in the cosmetic substance loading device 100 can be used, reducing waste of cosmetic substances and improving the utilization rate of cosmetic substances. In addition, the timely replenishment of the transparent element 20 by the cosmetic substances in the first sub-region 101 also allows the user to pick up more cosmetic substances each time, resulting in a better user experience.

[0096] In some embodiments, the user can use their finger to press through the material part 20 directly through the first opening 1021 to take the material, or use a makeup tool (e.g., a brush, powder puff, etc.) to press through the material part 20 through the first opening 1021 to take the material.

[0097] In some embodiments, the cosmetic material loading device 100 may be fitted with a housing or may not be fitted with a housing; a cover may be provided at the first opening 1021 to cover the transparent material 20, or the cover may not be provided.

[0098] In some embodiments, the first sub-region 101 and the second sub-region 102 are distributed along the axial direction of the housing 10.

[0099] The axial direction of housing 10 can be seen Figure 7 The Z direction in the equation.

[0100] By adopting the technical solution of this embodiment, the arrangement of the first sub-region 101 and the second sub-region 102 is simple, and the arrangement of the cosmetic substance and the transparent part 20 is simple, which can facilitate processing and manufacturing.

[0101] Please refer to the following: Figures 9-11 In some embodiments, a partition 30 is provided in the receiving cavity 1001, which divides the receiving cavity 1001 into a first sub-region 101 and a second sub-region 102. The partition 30 is provided with a first through hole 301 connecting the first sub-region 101 and the second sub-region 102.

[0102] The partition 30 can refer to a dividing structure within the housing 10, which divides the receiving cavity 1001 into two parts: a first sub-region 101 and a second sub-region 102. The partition 30 can be integrally formed with the housing 10, or it can be formed separately from the housing 10 and then assembled together. The material of the partition 30 can be the same as or different from that of the housing 10; the material of the partition 30 can be plastic, metal, etc.

[0103] The shape of the partition 30 can be various. For example, the partition 30 can be a flat plate. For example, the partition 30 can also be a plate with a central protrusion. For example, the partition 30 can be an arc-shaped plate, which can protrude toward the first sub-region 101 or toward the second sub-region 102.

[0104] The first through hole 301 penetrates the partition 30 to connect the first sub-region 101 and the second sub-region 102. The number of first through holes 301 can be one or more, and the shape of the first through hole 301 can be various, such as circular, polygonal, etc.

[0105] By adopting the technical solution of this embodiment, the cosmetic substance in the first sub-area 101 flows through the first through hole 301 to the material permeable member 20 in the second sub-area 102, and is then used by the user; while the partition 30 can block the cosmetic substance, reduce the amount of cosmetic substance in the first sub-area 101 flowing to the material permeable member 20, reduce the risk of leakage of cosmetic substance flowing out through the material permeable member 20, reduce waste of cosmetic substance, and improve the use effect of cosmetic substance loading device 100.

[0106] In some embodiments, the partition 30 includes a fixing portion 31 and a protrusion 32. The fixing portion 31 is connected between the inner peripheral wall of the housing 10 and the protrusion 32. The peripheral wall of the protrusion 32 is provided with a first through hole 301. The protrusion 32 protrudes relative to the fixing portion 31 toward the first sub-region 101 and forms a sub-cavity 3201. The sub-cavity 3201 forms at least a portion of the second sub-region 102. Alternatively, the protrusion 32 protrudes relative to the fixing portion 31 toward the second sub-region 102 and forms a sub-cavity 3201. The sub-cavity 3201 forms at least a portion of the first sub-region 101.

[0107] As an example, the middle portion of the partition 30 protrudes towards either the first sub-region 101 or the second sub-region 102. The protruding part of the partition 30 is called the protrusion 32, and the portion of the partition 30 connecting the protrusion 32 and the housing 10 is called the fixing part 31. The hollow cavity formed inside the protrusion 32 is called the sub-cavity 3201. The peripheral wall of the protrusion 32 can refer to the annular sidewall surrounding the central axis of the protrusion 32, through which the first through hole 301 passes. The central axis of the protrusion 32 can be found in [reference needed]. Figure 9 Line A in the middle.

[0108] When the protrusion 32 protrudes toward the first sub-region 101 relative to the fixing part 31, the sub-cavity 3201 is part of the second sub-region 102, or the entire sub-cavity 3201 is the second sub-region 102; for example, the material-permeable member 20 can extend into the sub-cavity 3201 and be adapted to the shape of the sub-cavity 3201; the insertion of the material-permeable member 20 into the sub-cavity 3201 can increase the volume of the material-permeable member 20, which can better adsorb cosmetic substances and reduce the risk of cosmetic substance leakage.

[0109] When the protrusion 32 protrudes toward the second sub-region 102 relative to the fixing part 31, the sub-cavity 3201 is part of the first sub-region 101, or the entire sub-cavity 3201 is the first sub-region 101.

[0110] By adopting the technical solution of this embodiment, the first through hole 301 is provided on the peripheral wall of the protrusion 32, so that the cosmetic material will not flow directly onto the material-permeable member 20 along the distribution direction of the first sub-region 101 and the second sub-region 102. The cosmetic material needs to flow to the periphery of the protrusion 32 first, and then flow onto the material-permeable member 20 through the first through hole 301 on the peripheral wall of the protrusion 32. This increases the resistance of the cosmetic material in the first sub-region 101 flowing onto the material-permeable member 20, reduces the risk of leakage of the cosmetic material, and helps to improve the performance of the cosmetic material loading device 100.

[0111] In some embodiments, the protrusion 32 includes a plurality of plate portions 321 and a plurality of sidewall portions 322. Along a first direction, the plurality of plate portions 321 are arranged at intervals. The plate portion 321 closest to the fixing portion 31 is arranged at intervals with the fixing portion 31. The plate portion 321 closest to the fixing portion 31 is connected to the fixing portion 31 through the sidewall portion 322. Adjacent plate portions 321 are connected through the sidewall portion 322. At least one sidewall portion 322 is provided with a first through hole 301. The first direction is the distribution direction of the first sub-region 101 and the second sub-region 102. The plate portions 321 located between the fixing portion 31 and the plate portion 321 farthest from the fixing portion 31 are all provided with a second through hole 3211, so that the plurality of plate portions 321 and the plurality of sidewall portions 322 together form a sub-cavity 3201. Along the first direction, the size of the plate portions 321 gradually increases or decreases in the direction perpendicular to the first direction.

[0112] As an example, the protrusion 32 has a multi-layered stepped structure, with one plate portion 321 forming one layer of the protrusion 32, and multiple plates portions 321 arranged at intervals along a first direction to form a multi-layered structure. The first direction may refer to the distribution direction of the first sub-region 101 and the second sub-region 102. For details, please refer to [reference needed]. Figure 7In the Z direction, adjacent layers are connected by sidewall portions 322, and the plate portion 321 closest to the fixing portion 31 is also connected to the fixing portion 31 by sidewall portions 322. Multiple sidewall portions 322 form the peripheral wall of the protrusion 32. Gaps are formed between adjacent plate portions 321 and between the plate portion 321 closest to the fixing portion 31 and the fixing portion 31. A second through hole 3211 is provided in the plate portion 321, which connects the two adjacent gaps, allowing the plate portion 321 and the sidewall portions 322 to form a sub-cavity 3201. A first through hole 301 is provided in the sidewall portion 322, allowing the cosmetic material in the first sub-area 101 to flow onto the material-transparent member 20 through the first through hole 301. The shape of the plate portion 321 can be various, such as circular or polygonal.

[0113] Along the first direction, the size of the plate portion 321 gradually increases or decreases in the direction perpendicular to the first direction, so that the size of the protrusion portion 32 along the direction perpendicular to the first direction becomes larger or smaller, and the protrusion portion 32 has a stepped structure.

[0114] For example, the protrusion 32 protrudes towards the first sub-region 101, and the plate portion 321 is circular. The dimension of the plate portion 321 perpendicular to the first direction is the diameter of the plate portion 321, with the diameter of the plate portion 321 increasing as it approaches the fixing portion 31. Of course, in other examples, the diameter of the plate portion 321 can also decrease as it approaches the fixing portion 31. The diameter of the second through hole 3211 can be the same as or different from the diameter of the corresponding plate portion 321; that is, the second through hole 3211 can be larger or smaller than the diameter of the corresponding plate portion 321.

[0115] In the multiple sidewall portions 322, a portion of the sidewall portions 322 may have a first through hole 301, or all of the sidewall portions 322 may have a first through hole 301. In this case, a sidewall portion 322 may have one or more first through holes 301.

[0116] For example, the first through hole 301 can penetrate the side wall portion 322, so that the side wall portion 322 includes one or more connecting posts 3221. When the side wall portion 322 includes one connecting post 3221, the two ends of the connecting post 3221 are respectively connected to two adjacent plate portions 321, and the connecting post 3221 and the two adjacent plate portions 321 together form the first through hole 301. When the side wall portion 322 includes multiple connecting posts 3221, the multiple connecting posts 3221 are distributed at intervals along the circumference of the plate portion 321, and the two ends of the connecting posts 3221 are respectively connected to two adjacent plate portions 321, and the two adjacent connecting posts 3221 and the two adjacent plate portions 321 together form the first through hole 301. Of course, in other examples, along the first direction, the first through hole 301 may not penetrate the side wall portion 322, so that the side wall portion 322 is an annular plate structure with a through hole.

[0117] By adopting the technical solution of this embodiment, the protrusion 32 has a stepped structure, and the number of first through holes 301 can be flexibly set to flexibly control the amount of cosmetic material in the first sub-region 101 flowing to the material-permeable member 20, thereby reducing the leakage of cosmetic material. In addition, when multiple sidewall portions 322 are provided with first through holes 301, the material-permeable member 20 can absorb cosmetic material in the first sub-region 101 at multiple positions along the first direction, which is beneficial to improving the uniformity of cosmetic material distribution in the material-permeable member 20 and improving the performance of the cosmetic material loading device 100.

[0118] Please refer to the following: Figure 12 In some embodiments, the partition 30 may not be provided inside the housing 10.

[0119] Please refer to the following: Figure 13 In some embodiments, the housing 10 includes a housing body 11 and a locking component 12. The housing body 11 is used to load cosmetic substances. The locking component 12 includes a first locking ring 121 and a second locking ring 122. One end of the first locking ring 121 is locked to one end of the housing body 11. A second opening 1011 is provided on the side of the housing body 11 opposite to the first locking ring 121. A partition 30 is provided inside the first locking ring 121. At least a portion of the material-transmitting member 20 is located inside the second locking ring 122. The other end of the first locking ring 121 is locked to the second locking ring 122 to clamp and fix the material-transmitting member 20. A first opening 1021 is provided on the side of the second locking ring 122 opposite to the first locking ring 121.

[0120] The shell body 11 is hollow inside and is used to contain cosmetic substances. The locking component 12 is also hollow inside and is used to contain part or all of the material-transmitting component 20. The locking component 12 includes a first locking ring 121 and a second locking ring 122. The partition 30 can be disposed inside the first locking ring 121. The partition 30 can be fixed by the locking of the first locking ring 121 with the shell body 11, and the material-transmitting component 20 can be fixed by the mutual locking of the first locking ring 121 and the second locking ring 122. Its structure is simple and convenient for the assembly and manufacturing of the cosmetic substance loading device 100.

[0121] For example, the internal space of the shell body 11 forms a first sub-region 101, and one end of the shell body 11 opens to form a third opening 111. A first retaining ring 121 engages and is fixed at the third opening 111, thereby fixing the partition 30 inside the shell body 11. At the same time, the inner holes of the first retaining ring 121 and the second retaining ring 122 together form a second sub-region 102. The first sub-region 101 and the second sub-region 102 are connected through the first through hole 301 of the partition 30, so that the cosmetic material in the receiving cavity 1001 can flow to the material-transparent part 20. The opening at the end of the second retaining ring 122 facing away from the shell body 11 forms a first opening 1021. The partition 30 and the first retaining ring 121 are integrally formed or separately formed and then assembled together.

[0122] By adopting the technical solution of this embodiment, the shell 10 adopts the structure of shell body 11 and engaging component 12, which is simple in structure and easy to process and manufacture; in addition, the engaging of shell body 11 with first retaining ring 121 and second retaining ring 122 can fix partition 30 and material-transparent component 20, which can reduce the number of parts, facilitate assembly, and reduce manufacturing costs.

[0123] In some embodiments, the inner wall of the first retaining ring 121 is formed with a first stepped surface 1211, and the shell body 11 is provided with a first engaging portion 112, which is inserted into the inner hole of the first retaining ring 121. The end face of the shell body 11 facing away from the second opening 1011 is used to abut against the first stepped surface 1211. The end of the shell body 11 is provided with a first groove 113, which is located outside the first engaging portion 112. The first retaining ring 121 is provided with a second engaging portion 1212, which engages in the first groove 113, thereby engaging the first retaining ring 121 in the shell body 11. This design at the end ensures reliable engagement between the first retaining ring 121 and the shell body 11, improving the sealing effect at the connection and reducing the risk of cosmetic leakage. It also reduces the risk of external air flowing between the shell body 11 and the first retaining ring 121 into the shell body 11, thus separating the cosmetic at the third opening 111 from the permeable part 20. This allows the cosmetic at the third opening 111 to have good contact with the permeable part 20, and during the automatic recovery process after compression, the permeable part 20 can effectively absorb the cosmetic inside the shell body 11. The second engaging portion 1212 and the groove wall of the first groove 113 can be engaged through a protrusion and a groove, or other methods can be used.

[0124] Of course, in other embodiments, the shell body 11 and the first retaining ring 121 can also adopt other structures for sealing and engaging.

[0125] In some embodiments, the outer peripheral wall of the material-permeable member 20 is provided with a clamping protrusion 21, the inner wall of the second retaining ring 122 forms a second stepped surface 1221, the first retaining ring 121 is provided with a third engaging portion 1213, the third engaging portion 1213 is inserted into the inner hole of the second retaining ring 122, and the clamping protrusion 21 abuts against the second stepped surface 1221, thereby fixing the material-permeable member 20; the first retaining ring 121 is provided with a second groove 1214, the second groove 1214 is located outside the third engaging portion 1213, the second retaining ring 122 is provided with a fourth engaging portion 1222, the fourth engaging portion 1222 engages in the second groove 1214, thereby making the second retaining ring 122 and the first retaining ring 121 engage. With this design, the engagement connection of the first retaining ring 121 and the second retaining ring 122 has good reliability, which is beneficial to improving the sealing effect at the connection of the first retaining ring 121 and the second retaining ring 122 and reducing the risk of leakage of cosmetic substances. The fourth engaging part 1222 and the groove wall of the second groove 1214 can be engaged by protrusion and groove, or other methods can be used for engagement.

[0126] Of course, in other embodiments, the first retaining ring 121 and the second retaining ring 122 can also use other structures for engagement connection.

[0127] In some embodiments, the transparent element 20 is attached to the partition 30.

[0128] As an example, the surfaces of the material-permeable member 20 and the partition 30 facing each other are abutted. A portion of the surface of the partition 30 facing away from the first sub-region 101 may abut the material-permeable member 20; for example, the material-permeable member 20 is not inserted into the sub-cavity 3201, the fixing portion 31 abuts the material-permeable member 20, and the plate portion 321 is not abutted with the material-permeable member 20; or, the material-permeable member 20 is inserted into the sub-cavity 3201, and the fixing portion 31 and a portion of the plate portion 321 abut the material-permeable member 20.

[0129] The entire surface of the partition 30 facing away from the first sub-region 101 can be fitted with the material-permeable member 20, such that the surface of the material-permeable member 20 facing the first sub-region 101 has the same or nearly the same shape as the surface of the partition 30, in order to better adsorb the cosmetic material in the first sub-region 101. For example, a portion of the material-permeable member 20 is inserted into the sub-cavity 3201, the fixing part 31 and all the plate parts 321 are fitted with the material-permeable member 20, and the shape of the portion of the material-permeable member 20 located in the sub-cavity 3201 is the same or nearly the same as the shape of the sub-cavity 3201, and also has a multi-layered stepped structure.

[0130] By adopting the technical solution of this embodiment, the cosmetic substance flowing out of the first through hole 301 can be directly adsorbed by the material permeable member 20, reducing the risk of the partition 30 and the material permeable member 20 being separated by air, so that the cosmetic substance flowing out of the first through hole 301 can be better adsorbed by the material permeable member 20, thereby improving the use effect of the cosmetic substance loading device 100.

[0131] In some embodiments, the receiving cavity 1001 is used to directly load cosmetic substances.

[0132] The cosmetic substance is directly loaded into the receiving cavity 1001, and the cosmetic substance is in direct contact with the cavity wall of the receiving cavity 1001; for example, the cosmetic substance is directly loaded into the first sub-region 101, and the cavity wall of the first sub-region 101 is in direct contact with the cosmetic substance.

[0133] By adopting the technical solution of this embodiment, cosmetic substances are directly loaded into the receiving cavity 1001. Its structure is simple and the number of parts is small, which helps to reduce the manufacturing cost of the cosmetic substance loading device 100.

[0134] In some embodiments, the outer peripheral wall of the material-transferring member 20 is provided with a clamping protrusion 21, the inner wall of the second retaining ring 122 forms a second stepped surface 1221, and the first retaining ring 121 is provided with a third engaging portion 1213. The third engaging portion 1213 is inserted into the inner hole of the second retaining ring 122, and the clamping protrusion 21 abuts against the second stepped surface 1221, so that the clamping protrusion 21 is clamped and fixed between the third engaging portion 1213 and the second stepped surface 1221, thereby fixing the material-transferring member 20; the first retaining ring 121 is provided with A second groove 1214 is provided, located outside the third engaging portion 1213. The second retaining ring 122 has a fourth engaging portion 1222, which engages within the second groove 1214, thereby engaging the second retaining ring 122 with the first retaining ring 121. This design ensures reliable engagement between the first retaining ring 121 and the second retaining ring 122, improving the sealing effect at their connection and reducing the risk of cosmetic leakage. The fourth engaging portion 1222 and the groove wall of the second groove 1214 can engage via a protrusion and a groove, or other methods can also be used.

[0135] Of course, in other embodiments, the first retaining ring 121 and the second retaining ring 122 can also use other structures for engagement connection.

[0136] See Figures 1-4 In some embodiments, the housing 10 includes a housing body 11 and a second retaining ring 122. The housing body 11 is used to hold cosmetic substances, and at least a portion of the material-permeable part 20 is located within the second retaining ring 122. The second retaining ring 122 is engaged with one end of the housing body 11 to clamp the material-permeable part 20.

[0137] The second opening 1011 is located at one end of the shell body 11 facing away from the second retaining ring 122, and the first opening 1021 is located on the side of the second retaining ring 122 facing away from the shell body 11.

[0138] By adopting the technical solution of this embodiment, the housing 10 adopts the structure of the housing body 11 and the second retaining ring 122, which has a simple structure and is easy to process and manufacture. In addition, the engagement of the housing body 11 and the second retaining ring 122 can fix the material-transparent part 20, which can reduce the number of parts and reduce the manufacturing cost.

[0139] In some embodiments, the outer peripheral wall of the material-permeable part 20 is provided with a clamping protrusion 21, the inner wall of the second retaining ring 122 forms a second stepped surface 1221, the shell body 11 is provided with a first engaging portion 112, the first engaging portion 112 is inserted into the inner hole of the second retaining ring 122, and the clamping protrusion 21 abuts against the second stepped surface 1221, thereby fixing the material-permeable part 20; the shell body 11 is provided with a first groove 113, the first groove 113 is located outside the first engaging portion 112, the second retaining ring 122 is provided with a fourth engaging portion 1222, the fourth engaging portion 1222 engages in the first groove 113, thereby making the shell body 11 and the second retaining ring 122 engage. This design has good reliability of the engagement connection between the shell body 11 and the second retaining ring 122, which is beneficial to improve the sealing effect at the connection between the shell body 11 and the second retaining ring 122 and reduce the risk of leakage of cosmetic substances. The fourth engaging part 1222 and the groove wall of the first groove 113 can be engaged by protrusions and grooves, or other methods can be used for engagement.

[0140] Of course, in other embodiments, the shell body 11 and the second retaining ring 122 can also be connected by other structures.

[0141] In some embodiments, the transparent element 20 includes one or more layers of sponge.

[0142] The transparent part 20 can be made of sponge, which can be one or more layers to meet different usage needs. The sponge has excellent liquid absorption properties, allowing it to store and transport cosmetic substances. Once saturated, the sponge can be used to apply cosmetics multiple times, such as dozens or hundreds of times. Simultaneously, the absorbed cosmetic substances are not easily spilled, ensuring that the user can apply cosmetic substances from the sponge regardless of the orientation of the first opening 1021. For example, the cosmetic substance loading device 100 can be placed flat, angled downwards, or vertically downwards. When placed flat, angled downwards, or vertically downwards, gravity causes the cosmetic substances to flow towards the sponge, which then absorbs the substances for repeated application.

[0143] In some embodiments, the sponge may also be covered with gauze or other components.

[0144] In some embodiments, the material permeable element 20 includes multiple layers of sponge, with at least two layers of sponge having different porosities.

[0145] As an example, the multi-layer sponge is stacked along the first direction.
