Description

Wearable hygiene products Technical Field

[0001] This invention relates to the field of hygiene care, and more particularly to a wearable hygiene product. Background Technology

[0002] Disposable diapers are widely used personal care products for infants, young children, patients unable to care for themselves, or individuals unable to care for themselves due to special circumstances. Existing disposable diapers typically consist of the following main components: a top layer, a core, a waterproof membrane, and a bottom layer. The top layer sits on top of the core. When the diaper is worn, the top layer comes into contact with the user's skin and guides urine to the core, allowing the core to absorb the urine. The top layer also covers the front, middle, and back of the crotch area to prevent leakage.

[0003] However, existing disposable diapers have some problems during use:

[0004] (1) After the surface layer and core absorb a certain amount of urine, the user's skin will continue to be in contact with the wet surface layer. This continuous contact not only reduces the user's comfort experience, but may also cause skin irritation.

[0005] (2) Skin irritation and eczema: Prolonged exposure to moisture and urine can cause skin irritation, which can then trigger eczema. Symptoms of eczema include 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 in existing disposable diapers.

[0007] The information disclosed in the background section of this invention is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Summary of the Invention

[0008] The purpose of this invention is to provide a wearable sanitary product that prevents the skin in the groin area from coming into contact with urine inside a soaked core, thereby preventing skin diseases and improving the user experience. Furthermore, the support portion ensures that the surface layer and the insulating layer do not completely adhere, creating a space between them to keep the insulating layer dry. The insulating layer extends forward from a predetermined position on the surface layer, preventing irritation to the skin of the buttocks, and the rear edge of the insulating layer connects to the predetermined position to prevent leakage from the back.

[0009] The present invention provides a wearable hygiene product, comprising: a surface layer that contacts the user's skin to allow liquid to pass through; an isolation layer disposed on the skin-contacting side of the surface layer and extending forward from a predetermined position on the surface layer, the distance from the predetermined position to the rear edge of the surface layer being a first predetermined length, the rear edge of the isolation layer being connected to the predetermined position, and the side edges of the isolation layer being connected to the surface layer; and a support portion that provides support to the isolation layer so that the surface layer and the isolation layer cannot be completely adhered.

[0010] Preferably, the isolation layer extends forward by a second predetermined length from a predetermined position on the surface layer, but does not extend to the front edge of the surface layer.

[0011] Preferably, the isolation layer extends forward from a predetermined position on the surface layer to the front edge of the surface layer and has an opening.

[0012] Preferably, the support includes an elastic retaining band that extends along the extension direction of the surface layer and is disposed between the surface layer and the isolation layer, so that the surface layer and the isolation layer cannot be completely adhered.

[0013] Preferably, the support includes an elastic retaining band, the extending direction of which is perpendicular to the extending direction of the surface layer, and the retaining band is disposed in the front half of the isolation layer.

[0014] Preferably, the wearable hygiene product further includes: a first three-dimensional guard, which is disposed on the side edge of the surface layer.

[0015] Preferably, the wearable hygiene product further includes: a second three-dimensional protective barrier, which is disposed on the left and right sides of the surface layer, and the support portion is disposed on the second three-dimensional protective barrier; the side edge of the isolation layer is fixedly connected to the second three-dimensional protective barrier.

[0016] Preferably, the surface layer has a partition area, the distance from the front edge of the partition area to the rear edge of the surface layer is a third predetermined length, the third predetermined length is greater than or equal to a first predetermined length, and the partition area does not have a water absorption function.

[0017] Preferably, the ratio of the first predetermined length to the length of the surface layer ranges from 2% to 75%.

[0018] Preferably, the ratio of the second predetermined length to the length of the surface layer ranges from 2% to 60%.

[0019] This invention relates to wearable sanitary products that use a separating layer to separate the surface layer from the skin, preventing the skin in the groin area from contacting urine inside the soaked core, thereby preventing skin diseases and improving the user experience. The support portion ensures that the surface layer and the separating layer do not completely adhere, creating a space between them to keep the separating layer dry. The separating layer extends forward from a predetermined position on the surface layer, preventing irritation to the buttocks skin, and its rear edge connects to a predetermined position to prevent leakage from the back.

[0036] In the embodiments of the present invention, "before" and "after" refer to the front and back of the wearable hygiene product after it has been unfolded.

[0037] The wearable hygiene products according to embodiments of the present invention will now be described with reference to Figures 1 to 9.

[0038] As shown in Figures 1 and 2, the wearable hygiene product of the present invention includes a surface layer 100, an isolation layer 200, and a support portion 300.

[0039] The surface layer 100 comes into contact with the user's skin to allow liquid to pass through and be absorbed by the core 500. The surface layer 100 is located on the side of the core 500 closest to the user's skin.

[0040] An isolation layer 200 is disposed on the skin-contacting side of the surface layer 100 and extends forward from a predetermined position 101 of the surface layer 100. The distance from the predetermined position 101 to the rear edge 102 of the surface layer 100 is a 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 connects to the predetermined position 101 to prevent rear leakage, and the side edges of the isolation layer 200 connect to the side edges 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%. More preferably, the ratio of the first predetermined length L1 to the length L4 of the surface layer 100 ranges from 2% to 20%.

[0041] The support portion 300 provides support to the isolation layer 200 so that the surface layer 100 and the isolation layer 200 cannot be completely adhered.

[0042] In this embodiment of the invention, the insulating layer 200 separates the surface layer 100 from the skin, preventing the skin in the groin area from coming into contact with urine inside the soaked core, thereby preventing skin diseases and improving the user experience. The support portion 300 ensures that the surface layer 100 and the insulating layer 200 do not completely adhere, creating a space between them, thus keeping the insulating layer 200 dry.

[0043] If the insulating layer 200 extends forward from the rear edge 102 of the surface layer 100, the surface layer corresponding to the buttocks will also come into contact with the insulating layer 200. When the part of the insulating layer 200 corresponding to the buttocks is made of a hydrophilic material, the moisture absorbed in this part will come into contact with the skin of the buttocks, thus causing irritation. When the part of the insulating layer 200 corresponding to the buttocks is made of a water-repellent material, the breathability will decrease. When this type of insulating layer 200 comes into contact with the skin of the buttocks for a long time, the temperature will become too high, thus causing irritation. In other words, if the insulating layer 200 extends forward from the rear edge 102 of the surface layer 100, it will irritate the skin of the buttocks.

[0044] The isolation layer 200 extends forward from the predetermined position 101 of the surface layer 100, which can prevent the isolation layer 200 from irritating the skin of the buttocks.

[0045] In an exemplary embodiment, as shown in Figures 2 and 4, the core 500 comprises, from the inside out: a first PE film 501, a first nonwoven fabric 502, a tufted fabric 503, a second nonwoven fabric 504, and a second PE film 505. The tufted fabric 503 is coated with polymer particles capable of absorbing urine.

[0046] The primary function of the first PE membrane 501 is to prevent urine backflow and keep the skin dry. The first PE membrane 501 has good breathability, effectively reducing skin allergies and discomfort. The first PE membrane 501 is in contact with the surface layer 100.

[0047] The primary function of the first nonwoven fabric 502 is to rapidly disperse urine and prevent localized accumulation. The first nonwoven fabric 502 has excellent absorbency and diffusion properties, enabling it to quickly transfer urine into the loose fabric 503.

[0048] As the core component of the core 500, the 503 fluffy fabric has attached polymer particles that expand rapidly after absorbing urine, forming a gel-like substance that effectively locks in moisture and prevents leakage.

[0049] The second nonwoven fabric 504 serves to further diffuse and fix urine, ensuring uniform absorption. The second nonwoven fabric 504 also possesses a certain degree of elasticity, adapting to the user's movements and maintaining the stability and fit of the core 500. The first nonwoven fabric 502 and the second nonwoven fabric 504 can be made of spunlace fabric, spunbond fabric, or spunmelt fabric. When selecting materials, the type of nonwoven fabric can be determined based on actual application requirements (such as strength, breathability, filtration effect, etc.). The first nonwoven fabric 502 and the second nonwoven fabric 504 can be made of the same material or different materials.

[0050] The second PE membrane 505 serves to prevent leakage and protect against urine seepage, while also keeping the core 500 clean and hygienic.

[0051] The material of the isolation layer 200 is usually made of materials with high water repellency, such as polyester, polypropylene or other synthetic fibers. These materials are specially treated to ensure that they have good waterproof performance.

[0052] In one embodiment, as shown in FIG1, the insulating layer 200 extends forward from a predetermined position 101 of the surface layer 100 by a second predetermined length L2, but 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 ranges from 2% to 60%. Preferably, the ratio of the second predetermined length L2 to the length L4 of the surface layer 100 ranges from 2% to 50%. More preferably, the ratio of the second predetermined length L2 to the length L4 of the surface layer 100 ranges from 2% to 20%.

[0053] Urine enters from the part of the surface layer 100 that is not blocked by the insulating layer 200, and then passes through the surface layer 100 to be absorbed by the core 500.

[0054] In another embodiment, as shown in FIG3, the isolation layer 200 extends forward from a predetermined position 101 of the surface layer 100 to the front edge 103 of the surface layer 100 and has an opening 202.

[0055] Urine enters through the opening 202 of the surface layer 100, then permeates the surface layer 100 and is absorbed by the core 500.

[0056] Compared to the implementation scheme in Figure 3, the surface layer 100 of the implementation scheme in Figure 1 has a larger contact area with the skin.

[0057] Compared to the embodiment in Figure 1, the opening 202 in the embodiment in Figure 3 is more conducive to the targeted absorption of urine by the male user. Specifically, the male user's genitals can pass through the opening 202 to contact the surface layer 100, thereby being targetedly absorbed by the surface layer 100.

[0058] In an exemplary embodiment, as shown in Figures 1 and 3, the support portion 300 includes an elastic retaining band 301 that extends along the extension direction of the surface layer 100 and is disposed between the surface layer 100 and the isolation layer 200, so that the surface layer 100 and the isolation layer 200 cannot be completely adhered.

[0059] The retaining band 301 can be made of elastic band, and the material of the retaining band 301 is not limited to this. It can be any form in the prior art, as long as it can achieve the above functions.

[0060] The rear end of the retaining band 301 is flush with and fixed to the rear end of the insulating layer 200. The front end of the retaining band 301 is flush with and fixed to the front end of the surface layer 100. Specifically, the retaining band 301 is fixed to the surface layer 100 and / or the insulating layer 200 by adhesive. Other fixing methods for the retaining band 301 may include sewing, heat pressing, etc. Sewing provides a stronger fixing effect and is suitable for applications requiring higher elasticity and durability. Through sewing, the retaining band 301 can be more firmly bonded to the surface layer 100 and / or the insulating layer 200, ensuring that the wearable hygiene product maintains good fit and leak-proof performance during long-term use. Heat pressing technology can use high temperature to tightly bond the retaining band 301 to the surface layer 100 and / or the insulating layer 200. Through heat pressing technology, a seamless connection between the retaining band 301 and the surface layer 100 and / or the insulating layer 200 can be achieved, further enhancing the fit and durability of the wearable hygiene product.

[0061] In the illustrated embodiment, the retaining strap 301 is set to two, but the number can be adjusted as needed, for example, it can be set to any number from 2 to 5.

[0062] In an exemplary embodiment, the support portion 300 includes an elastic retaining band 302, the extension direction of which is perpendicular to the extension direction of the surface layer 100. The retaining band 302 is disposed in the front half of the isolation layer 200 so that the surface layer 100 and the isolation layer 200 cannot be completely adhered. Preferably, the retaining band 302 is disposed at the front edge 201 of the isolation layer 200 (see FIG. 5 for details).

[0063] The retaining band 302 can be made of elastic band, and the material of the retaining band 302 is not limited to this. It can be any form in the prior art, as long as it can achieve the above functions.

[0064] Both ends of retaining tape 302 are flush with and fixed together with both ends of insulating layer 200. The fixing method of both ends of retaining tape 302 is the same as that of retaining tape 301, and will not be described again here.

[0065] In an exemplary embodiment, as shown in Figures 1, 3, 5, and 6, the wearable hygiene product of this embodiment further includes a first three-dimensional guard 401, which is disposed on the side edge of the surface layer 100. The length of the first three-dimensional guard 401 is approximately equal to the length of the surface layer 100.

[0066] The first three-dimensional protective enclosure 401 has the following functions:

[0067] (1) The first three-dimensional protective barrier 401 forms a surrounding barrier in the leg area of ​​the wearable hygiene product (such as a diaper), which can effectively prevent urine from leaking from both sides and ensure the leak-proof performance of the wearable hygiene product.

[0068] (2) The first three-dimensional guard 401 can better fit the user's leg curves, providing a more comfortable wearing experience and reducing friction and discomfort caused by non-fitting.

[0069] (3) The first three-dimensional protective barrier 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.

[0070] In an exemplary embodiment, as shown in FIG6, the wearable hygiene product of the present invention further includes a second three-dimensional guard 402, the second three-dimensional guard 402 being disposed on the left and right sides of the surface layer 100, and a support portion 300 being disposed on the second three-dimensional guard 402, that is, one end of the support portion 300 being connected to the second three-dimensional guard 402 on the left side, and the other end of the support portion 300 being connected to the second three-dimensional guard 402 on the right side.

[0071] The side edge of the isolation layer 200 is fixedly connected to the second three-dimensional enclosure 402.

[0072] In an exemplary embodiment, as shown in FIG1, the surface layer 100 has a partition area 105. 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. The third predetermined length L3 is greater than or equal to a first predetermined length L1. That is, the front edge of the partition area 105 is further forward than the predetermined position 101 (see FIG7 and FIG8) or flush with the predetermined position 101 (see FIG1 and FIG9). The partition area 105 does not have a water absorption function, so that the portion of the surface layer 100 located on 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-back direction is greater than or equal to 1 mm.

[0073] The presence of the partition zone 105 prevents urine from being conducted from the part of the surface layer 100 in front of the partition zone 105 to the part of the surface layer 100 behind the partition zone 105, thus avoiding skin irritation caused by the moisture in the part of the surface layer 100 behind the partition zone 105.

[0074] The process of forming partition zone 105 involves first heating the area and then subjecting it to ultrasonic treatment.

[0075] Other components and functions of the wearable hygiene products according to the embodiments of the present invention are known to those skilled in the art, and will not be described in detail to reduce redundancy.

[0076] The operation of the wearable hygiene product according to the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0077] When wearable sanitary products are worn by the user, the insulating layer 200 comes into contact with the skin of the groin area. The support portion 300 ensures that the surface layer 100 and the insulating layer 200 do not completely adhere to each other, so that there is a space between the surface layer 100 and the insulating layer 200, thereby keeping the insulating layer 200 dry.

[0078] In the embodiment shown in Figure 1, urine enters from the portion of the surface layer 100 that is not blocked by the insulating layer 200, and then passes through the surface layer 100 to be absorbed by the core 500.

[0079] In the embodiment shown in Figure 3, urine enters through the opening 202 of the surface layer 100, then permeates the surface layer 100, and is absorbed by the core 500.
