Technical Field
[0001] The invention relates to the field of hygienic care, and in particular to a wearable hygienic product. Background Art
[0002] Diapers are personal care products widely used by infants, patients who cannot take care of themselves, or people who cannot take care of themselves due to special reasons. Existing diapers usually include the following main components: a surface layer, a core body, a waterproof film, and a bottom layer. Among them, the surface layer is arranged on the core body. When the diaper is worn on a person, the surface layer contacts the user's skin and guides urine to the core body, so that the core body absorbs urine. The surface layer also wraps the front, middle, and back of the crotch of the human body to ensure that urine does not leak out.
[0003] However, there are some problems with the existing diapers during use:
[0004] (1) When the surface layer and the core absorb a certain amount of urine, the user's skin will continue to contact the soaked surface layer. This continuous contact not only reduces the user's comfort experience, but may also cause irritation to the skin.
[0005] (2) Skin irritation and eczema: Prolonged contact with moisture and urine can cause skin irritation, which in turn can induce eczema. Symptoms of eczema include the appearance of red papules on the skin, accompanied by itching, which seriously affects the user's comfort and health.
[0006] Therefore, there is a need for further improvement of existing diapers.
[0007] The information disclosed in this background section is only intended to enhance understanding of the overall background of the invention and should not be taken as an acknowledgement or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0040] The front and back in the embodiment of the present invention refer to the front and back after the wearable sanitary product is unfolded.
[0041] Combine the following Figures 1 to 9 A wearable sanitary product according to an embodiment of the present invention will be described.
[0042] like Figure 1 and Figure 2 As shown, the wearable sanitary product according to the embodiment of the present invention includes a surface layer 100 , an isolation layer 200 and a supporting portion 300 .
[0043] The surface layer 100 contacts the user's skin to allow liquid to penetrate therethrough and thus be absorbed by the core 500. The surface layer 100 is disposed on a side of the core 500 that is close to the user's skin.
[0044] The isolation layer 200 is arranged on the side of the surface layer 100 that contacts the skin, and extends from the predetermined position 101 of the surface layer 100 to the front side, and the distance from the predetermined position 101 to the rear edge 102 of the surface layer 100 is the first predetermined length L1. The ratio of the first predetermined length L1 to the length L4 of the surface layer 100 ranges from 2% to 75%. The rear edge of the isolation layer 200 is connected to the predetermined position 101 to prevent rear leakage, and the side edge of the isolation layer 200 is connected to the side edge of the surface layer 100 to prevent side leakage. Preferably, the ratio of the first predetermined length L1 to the length L4 of the surface layer 100 ranges from 2% to 50%. Further preferably, the ratio of the first predetermined length L1 to the length L4 of the surface layer 100 ranges from 2% to 20%.
[0045] The support portion 300 provides a support force to the isolation layer 200 so that the surface layer 100 and the isolation layer 200 cannot be completely attached to each other.
[0046] The embodiment of the present invention separates the surface layer 100 from the skin through the isolation layer 200, thereby preventing the skin of the crotch from contacting with the urine in the core body, thereby preventing skin diseases and improving the user experience. The support part 300 can ensure that the surface layer 100 and the isolation layer 200 cannot be completely attached, so that there is a space between the surface layer 100 and the isolation layer 200, thereby keeping the isolation layer 200 dry.
[0047] If the isolation layer 200 extends forward from the rear edge 102 of the surface layer 100, the surface layer corresponding to the buttocks will also contact the isolation layer 200. When the isolation layer 200 corresponding to the buttocks is made of a hydrophilic material, the moisture absorbed by this part will contact the skin of the buttocks, thereby irritating the skin of the buttocks. When the isolation layer 200 corresponding to the buttocks is made of a water-repellent material, the air permeability will be reduced. When the isolation layer 200 of this material is in contact with the skin of the buttocks for a long time, it will cause the temperature to be too high, thereby irritating the skin of the buttocks. That is, if the isolation layer 200 extends forward from the rear edge 102 of the surface layer 100, it will irritate the skin of the buttocks.
[0048] The isolation layer 200 extends from a predetermined position 101 of the surface layer 100 toward the front side, so as to prevent the isolation layer 200 from irritating the skin of the buttocks.
[0049] In an exemplary embodiment, Figure 2 and Figure 4 As shown, the core 500 includes, from inside to outside, a first PE film 501, a first non-woven fabric 502, a fluffy fabric 503, a second non-woven fabric 504, and a second PE film 505. The fluffy fabric 503 is attached with polymer particles, which can absorb urine.
[0050] The main function of the first PE film 501 is to prevent urine from seeping back and keep the skin dry. The first PE film 501 has good air permeability and can effectively reduce skin allergies and discomfort. The first PE film 501 is in contact with the surface layer 100.
[0051] The main function of the first non-woven fabric 502 is to quickly disperse urine and avoid local accumulation. The first non-woven fabric 502 has good water absorption and diffusion properties and can quickly transfer urine to the fluffy fabric 503.
[0052] The fluffy cloth 503 is the core part of the core body 500. The polymer particles attached to the fluffy cloth 503 will expand rapidly after absorbing urine to form a gel-like substance, thereby effectively locking in moisture and preventing leakage.
[0053] The function of the second nonwoven fabric 504 is to further diffuse and fix urine to ensure uniform absorption. The second nonwoven fabric 504 also has a certain elasticity, which can adapt to the user's activities and maintain the stability and fit of the core 500. The first nonwoven fabric 502 and the second nonwoven fabric 504 can be made of spunlace, spunbond or spunmelt. When selecting materials, you can decide which type of nonwoven fabric to use based on actual application requirements (such as strength, air permeability, filtering effect, etc.). The first nonwoven fabric 502 and the second nonwoven fabric 504 can be made of the same material or different materials.
[0054] The second PE film 505 plays a role of leak prevention and protection, preventing urine from leaking to the outside, while keeping the core body 500 clean and hygienic.
[0055] The isolation layer 200 is usually made of a material with high water repellency, such as polyester, polypropylene or other synthetic fibers. These materials are specially treated to ensure that they have good waterproof properties.
[0056] In one embodiment, if Figure 1 As shown, the isolation layer 200 extends from the predetermined position 101 of the surface layer 100 to the front side by a second predetermined length L2, and does not extend to the front edge 103 of the surface layer 100. The ratio of the second predetermined length L2 to the length L4 of the surface layer 100 is in the range of 2% to 60%. Preferably, the ratio of the second predetermined length L2 to the length L4 of the surface layer 100 is in the range of 2% to 50%. Further preferably, the ratio of the second predetermined length L2 to the length L4 of the surface layer 100 is in the range of 2% to 20%.
[0057] Urine enters from the portion of the surface layer 100 that is not blocked by the isolation layer 200 , and then passes through the surface layer 100 , thereby being absorbed by the core body 500 .
[0058] In another embodiment, Figure 3 As shown, the isolation layer 200 extends from a predetermined position 101 of the surface layer 100 toward the front side to the front edge 103 of the surface layer 100 , and has an opening 202 .
[0059] Urine enters from the opening 202 of the surface layer 100 , passes through the surface layer 100 , and is then absorbed by the core 500 .
[0060] Compared to Figure 3 implementation plan, Figure 1 The surface layer 100 of the embodiment has a larger contact area with the skin.
[0061] Compared to Figure 1 implementation plan, Figure 3 The opening 202 of the embodiment is more conducive to the fixed-point absorption of urine of male users. Specifically, the genitals of male users can pass through the opening 202 to contact the surface layer 100, so as to be absorbed by the surface layer 100 at a fixed point.
[0062] In an exemplary embodiment, Figure 1 and Figure 3 As shown, the support portion 300 includes an elastic retaining belt 301 extending along the extension direction of the surface layer 100 . The retaining belt 301 is arranged between the surface layer 100 and the isolation layer 200 so that the surface layer 100 and the isolation layer 200 cannot be completely attached.
[0063] The retaining belt 301 may be made of rubber band, and the material of the retaining belt 301 is not limited thereto. The retaining belt 301 may be any form in the prior art as long as it can achieve the above functions.
[0064] The rear end of the retaining belt 301 is flush with the rear end of the isolation layer 200 and fixed. The front end of the retaining belt 301 is flush with the front end of the surface layer 100 and fixed. Specifically, the retaining belt 301 is fixed on the surface layer 100 and / or the isolation layer 200 by pasting. The fixing method of the retaining belt 301 can also include other technical means such as suturing and hot pressing. The suturing method can provide a stronger fixing effect and is suitable for occasions requiring higher elasticity and durability. Through suturing, the retaining belt 301 can be more firmly combined with the surface layer 100 and / or the isolation layer 200 to ensure that the wearable sanitary product still maintains good fit and leakproof performance during long-term use. Hot pressing technology can use high temperature to tightly combine the retaining belt 301 with the surface layer 100 and / or the isolation layer 200. Through hot pressing technology, seamless connection between the retaining belt 301 and the surface layer 100 and / or the isolation layer 200 can be achieved, further enhancing the fit and durability of the wearable sanitary product.
[0065] In the illustrated embodiment, two retaining belts 301 are provided, but the number thereof can be adjusted according to circumstances, for example, can be set to any number between 2 and 5.
[0066] In an exemplary embodiment, the support portion 300 includes an elastic retaining belt 302, the extension direction of the retaining belt 302 is perpendicular to the extension direction of the surface layer 100, and the retaining belt 302 is arranged at the front half of the isolation layer 200 so that the surface layer 100 and the isolation layer 200 cannot be completely attached. Preferably, the retaining belt 302 is arranged at the front edge 201 of the isolation layer 200 (see Figure 5 ).
[0067] The retaining belt 302 may be made of rubber band, and the material of the retaining belt 302 is not limited thereto. The retaining belt 302 may be in any form in the prior art as long as it can achieve the above functions.
[0068] The two ends of the retaining belt 302 are flush with and fixed to the two ends of the isolation layer 200. The fixing method of the two ends of the retaining belt 302 is the same as that of the retaining belt 301, which will not be repeated here.
[0069] In an exemplary embodiment, Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the wearable sanitary product according to the embodiment of the present invention further comprises a first three-dimensional guard 401, which is arranged at the side edge of the surface layer 100. The length of the first three-dimensional guard 401 is substantially equal to the length of the surface layer 100.
[0070] The first three-dimensional guardrail 401 has the following functions:
[0071] (1) The first three-dimensional guard 401 can effectively prevent urine from leaking from both sides by forming a surrounding barrier in the leg area of the wearable sanitary product (such as a diaper), thereby ensuring the leakage-proof performance of the wearable sanitary product.
[0072] (2) The first three-dimensional guard 401 can better fit the leg curve of the user, provide a more comfortable wearing experience, and reduce friction and discomfort caused by poor fit.
[0073] (3) The first three-dimensional guard 401 is usually made of breathable material, which can increase the breathability of the leg area, reduce moisture accumulation, and reduce the risk of skin irritation and eczema.
[0074] In an exemplary embodiment, Figure 6 As shown, the wearable sanitary product of the embodiment of the present invention further includes a second three-dimensional guardrail 402, which is arranged on the left and right sides of the surface layer 100, and the support part 300 is arranged on the second three-dimensional guardrail 402, that is, one end of the support part 300 is connected to the second three-dimensional guardrail 402 on the left, and the other end of the support part 300 is connected to the second three-dimensional guardrail 402 on the right.
[0075] The side edge of the isolation layer 200 is fixedly connected to the second three-dimensional protective enclosure 402 .
[0076] In an exemplary embodiment, Figure 1 As shown, the surface layer 100 has a partition area 105, and the distance from the front edge of the partition area 105 to the rear edge 102 of the surface layer 100 is a third predetermined length L3, and the third predetermined length L3 is greater than or equal to the first predetermined length L1, that is, the front edge of the partition area 105 is further forward than the predetermined position 101 (see Figure 7 and Figure 8 ) or flush with the predetermined position 101 (see Figure 1 and Fig. 9 ), the partition area 105 does not have a water absorption function, so that the portion of the surface layer 100 located at the rear side of the partition area 105 may not have a water absorption function. The length of the partition area 105 in the front-to-back direction is greater than or equal to 1 mm.
[0077] The existence of the partition area 105 prevents urine in the portion of the surface layer 100 located in front of the partition area 105 from being transferred to the portion of the surface layer 100 located behind the partition area 105, thereby preventing the portion of the surface layer 100 located behind the partition area 105 from becoming wet and causing skin irritation.
[0078] The process of forming the partition area 105 is to first heat the area and then perform ultrasonic treatment.
[0079] Other structures and functions of the wearable sanitary product according to the embodiment of the present invention are known to those skilled in the art, and will not be described in detail to reduce redundancy.
[0080] The operation of the wearable sanitary product according to the embodiment of the present invention will be described below with reference to the accompanying drawings.
[0081] When the wearable sanitary product is worn on the user, the isolation layer 200 contacts the skin of the crotch. The support part 300 can ensure that the surface layer 100 and the isolation layer 200 cannot be completely attached, so that there is a space between the surface layer 100 and the isolation layer 200, thereby keeping the isolation layer 200 dry.
[0082] exist Figure 1 In the embodiment of the present invention, urine enters from the portion of the surface layer 100 that is not blocked by the isolation layer 200 , and then passes through the surface layer 100 , thereby being absorbed by the core 500 .
[0083] exist Figure 3 In the embodiment of the present invention, urine enters from the opening 202 of the surface layer 100 and then passes through the surface layer 100 to be absorbed by the core 500.
