Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments and accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0022] This utility model embodiment provides a postpartum sanitary pant, such as Figure 1 and Figure 2 As shown, the device includes a front waist section 100, a back waist section 200, and an absorbent core 300. The two ends of the absorbent core 300 are connected to the front waist section 100 and the back waist section 200, respectively. The front waist section 100 and the back waist section 200 are connected by a movable component 400, which allows for adjustment of the waist size. The front end of the absorbent core 300 has a breathable component 500, which consists of a breathable window 501 and a sealing patch 502. One end of the sealing patch 502 is fixedly connected to the periphery of the breathable window 501, allowing the sealing patch 502 to pivot around the fixed edge, thus opening or closing the breathable window 501. The absorbent core 300 has several flexible, malleable fixing strips 600, allowing for shape adjustment of the absorbent core 300 by adjusting the shape of these flexible, malleable fixing strips 600.

[0023] The postpartum sanitary pants of this utility model are composed of a front waistband 100, a back waistband 200, and an absorbent core 300. The front waistband 100 and the back waistband 200 are connected by a movable part 400, so that the waistband of the sanitary pants can be adjusted according to actual needs. By setting a breathable part 500 at the front end of the absorbent core 300 and further setting a flexible and malleable fixing strip 600 in the middle of the absorbent core 300, a breathable channel can be created between the human body and the sanitary pants, thereby significantly enhancing the breathability of the sanitary pants. In this way, not only can comfort be ensured and bedding can be avoided, but bacterial growth can also be reduced, which is conducive to postpartum wound recovery.

[0024] Continue to refer to Figure 1 and Figure 2 According to some preferred embodiments, the shape of the ventilation window 501 is the same as the shape of the sealing patch 502, and the sealing patch 502 can completely cover the ventilation window 501; the sealing patch 502 covers the surface of the ventilation window 501 and / or the surrounding area of ​​the ventilation window 501 is provided with an adhesive layer 503, and the sealing patch 502 can repeatedly open and close the ventilation window 501 through the adhesive layer 503.

[0025] In this utility model, such as Figure 1 and Figure 2 As shown, a ventilation window 501 is provided at the front end of the absorbent core 300 (i.e., the end near the user's abdomen). This ventilation window 501 is a through-hole structure. A sealing patch 502 with the same shape as the ventilation window 501 is provided at one edge of the ventilation window 501. The sealing patch 502 is slightly larger than the ventilation window 501, which can completely cover the ventilation window 501. Furthermore, an adhesive layer 503 is provided on the ventilation window 501 or the sealing patch 502, so that the sealing patch 502 can pivot around the fixedly connected edge and be pressed from the periphery of the ventilation window 501. The ventilation window 501 is closed and then peeled open to expose it, thus opening the ventilation window 501. This allows for repeated opening and closing of the ventilation window 501 according to actual ventilation needs. When the ventilation window 501 is open, the shape of the absorbent core 300 is adjusted using the flexible, malleable fixing strip 600 within the absorbent core 300, creating a ventilation channel between the body and the absorbent core 300, thereby adjusting the breathability of the sanitary pants. When the ventilation window 501 is closed, the sealing patch 502 remains part of the absorbent core 300, preventing liquid leakage.

[0026] It should be noted that in this utility model, the sealing patch 502 and the absorbent core 300 have the same composition structure. The size of the ventilation window 501 and the sealing patch 502 can be adjusted according to actual needs. In this utility model, the sealing patch 502 is preferably arched. When in use, the sealing patch 502 opens upward, the straight edge of the arch is connected to the absorbent core 300, and the arc is separated from the sanitary pants to form an opening.

[0027] like Figure 3 As shown, according to some preferred embodiments, the absorbent core 300 includes a liquid-permeable surface layer 301, an absorbent layer 302, and a leak-proof bottom layer 303 arranged sequentially from top to bottom; wherein, the flexible and malleable fixing strip 600 is located between the absorbent layer 302 and the leak-proof bottom layer 303.

[0028] In this invention, a flexible and malleable fixing strip 600 is provided between the absorbent layer 302 and the leak-proof bottom layer 303. The flexible and malleable fixing strip 600 has shape malleability, can change shape when subjected to force, and can maintain its shape when the force is removed. This not only ensures the good comfort and absorbency of the absorbent core 300, but also allows the postpartum sanitary pants to maintain a good fit with the user. At the same time, the breathability of the absorbent core 300 can be enhanced by adjusting the flexible and malleable fixing strip 600.

[0029] In this utility model Figure 3 In this invention, the structural layers are peeled off from each other. This is to clearly show the positional relationship between the structural layers of this invention. However, it should be understood that the structural layers of this invention are actually tightly fitted and / or partially fitted together.

[0030] According to some preferred embodiments, such as Figure 2 As shown, the number of flexible and malleable fixing strips 600 is 2-20 (for example, 2, 4, 6, 8, 10, 12 or 20); the flexible and malleable fixing strips 600 are located on both sides of the absorbent core 300.

[0031] In this invention, to ensure good plasticity of the absorbent core 300, a certain number of flexible and malleable fixing strips 600 are provided between the absorbent layer 302 and the leak-proof bottom layer 303. Preferably, the flexible and malleable fixing strips 600 are provided on both sides of the absorbent layer 302 and the leak-proof bottom layer 303 in the width direction. This not only facilitates the quick formation of a breathable channel between the user and the absorbent core 300 by adjusting the shape of the absorbent core 300, but also avoids adverse effects on the liquid absorption performance of the absorbent core 300.

[0032] It should be noted that the specific type of flexible and malleable fixing strip 600 is not specifically limited in this utility model. As long as the shape can be malleable without affecting the comfort of the absorbent core 300, it can be a plastic fixing strip.

[0033] According to some preferred embodiments, the liquid-permeable surface layer 301 includes at least three layers of bamboo fiber nonwoven fabric, each liquid-permeable surface layer 301 having a plurality of first through holes 3011, and the positions of the first through holes 3011 in each liquid-permeable surface layer 301 being corresponding.

[0034] According to some preferred embodiments, along the direction from the liquid-permeable surface layer 301 to the leak-proof bottom layer 303, the diameter of the first through hole 3011 on each liquid-permeable surface layer 301 gradually decreases.

[0035] The liquid-permeable surface layer 301 is in direct contact with the user. In this invention, bamboo fiber non-woven fabric with certain antibacterial properties and good skin-friendliness is used as the liquid-permeable surface layer 301. This allows the liquid-permeable surface layer 301 to have good air permeability, instant water absorption, and antibacterial, mite-removing, and deodorizing properties. Furthermore, by setting a number of first through holes 3011 on each layer of the liquid-permeable surface layer 301, and the pore size of the first through holes 3011 gradually decreases along the direction from the liquid-permeable surface layer 301 to the leak-proof bottom layer 303, the first through holes 3011 on the liquid-permeable surface layer 301 are generally hourglass-shaped. This not only enhances the liquid absorption and drainage performance of the liquid-permeable surface layer 301, but also forms vents to further enhance air permeability, thereby ensuring good dryness of the liquid-permeable surface layer 301.

[0036] According to some preferred embodiments, the liquid-permeable surface layer 301 comprises three layers of bamboo fiber nonwoven fabric; wherein, the first layer of bamboo fiber nonwoven fabric has a pore size of 60-80 mesh and a bamboo fiber count of 50-80; the second layer of bamboo fiber nonwoven fabric has a pore size of 50-60 mesh and a bamboo fiber count of 30-50; and the third layer of bamboo fiber nonwoven fabric has a pore size of 25-50 mesh and a bamboo fiber count of 20-30.

[0037] In this invention, the liquid-permeable surface layer 301 is made of three layers of bamboo fiber nonwoven fabric, and the pore size and thread count of each layer of bamboo fiber nonwoven fabric are selected. This not only makes it more comfortable to be in direct contact with the user's skin, but also allows for rapid absorption of liquid. In addition, when it works together with the absorbent layer 302, it can effectively prevent bacteria from growing on the surface of the postpartum sanitary pants, ensuring a better user experience.

[0038] It should be noted that the shape of the first through hole 3011 is not particularly limited in this utility model. For example, it can be circular, elliptical, heart-shaped or triangular. At the same time, the arrangement of the first through holes 3011 on the liquid-permeable surface layer 301 and the spacing between adjacent first through holes 3011 can be adjusted according to actual needs.

[0039] According to some preferred embodiments, such as Figure 4 As shown, the absorbent layer 302 is composed of several layers of super absorbent resin composite paper; wherein, each layer of super absorbent resin composite paper is provided with several second through holes 3021, and the second through holes 3021 have a honeycomb structure on the surface of the super absorbent resin composite paper.

[0040] In this invention, the absorbent layer 302 serves as the main liquid-absorbing functional layer of the absorbent core 300. The absorbent layer 302 is composed of several layers of highly absorbent resin composite paper with excellent liquid absorption and retention properties. Several second through-holes 3021 are provided on the surface of each layer of highly absorbent resin composite paper. The second through-holes 3021 are hexagonal, creating a honeycomb structure on the highly absorbent resin composite paper. Furthermore, by combining multiple layers of highly absorbent resin composite paper with a honeycomb structure to form the absorbent layer 302, the second through-holes 3021 on the absorbent layer 302 form a three-dimensional, suspended honeycomb structure, giving the absorbent layer 302 advantages such as good air permeability and rapid absorption. Further, the basis weight of the highly absorbent resin composite paper is 60-350 g / m³. 2 .

[0041] According to some preferred embodiments, the breathable bottom layer is composed of a breathable PE film composite nonwoven fabric, wherein the nonwoven fabric is a hot-air nonwoven fabric or a spunbond nonwoven fabric. The length of the elastic band 401 is 3-15cm, and the length of the magic hook 402 is 3-5cm.

[0042] According to some preferred embodiments, both the front waist 100 and the back waist 200 are composed of two layers of non-woven fabric, with spandex or elastic fabric laid between the two layers of non-woven fabric; the movable part 400 consists of at least two elastic straps 401, one end of each elastic strap 401 is connected to one end of the back waist 200, and the other end of the elastic strap 401 is attached with Velcro, so that the waist size of the sanitary pants can be adjusted by adjusting the attachment position of the Velcro on the front waist 100.

[0043] In this invention, both the front waist section 100 and the back waist section 200 of the waistband structure are made of two layers of nonwoven fabric. The inner and outer nonwoven fabrics are made of soft and comfortable spunbond nonwoven fabric or hot-air nonwoven fabric, and the basis weight of the nonwoven fabric is 10-35 g / m². 2To achieve comfort and functionality, and to ensure the elasticity of the waistband, spandex filaments are laid between the two layers of non-woven fabric in the front waistband 100 and the back waistband 200. The number of spandex filaments can be set according to actual needs, for example, 1-50 filaments. To facilitate adaptive adjustment of the waist size, elastic bands 401 are designed on both sides of the back waistband 200. The elastic bands 401 are elastic materials that deform under stress and return to their shape after the stress is removed. Velcro hooks 402 are provided at the open ends of the elastic bands 401, and Velcro is provided at the corresponding positions in the front waistband 100. The Velcro hooks 402 are connected to the Velcro of the front waistband 100 to achieve adaptive adjustment of the waist size and tightness of the sanitary panties.

[0044] In summary, in this invention, the liquid-permeable surface layer is composed of multiple layers of bamboo fiber material with antibacterial properties from top to bottom, with the pore size increasing towards the bottom to form a breathable layer. The absorbent core uses absorbent paper with a three-dimensional honeycomb suspension structure. This type of absorbent paper has a large absorption capacity and good dryness, and can quickly absorb human excrement, keeping the microenvironment dry and reducing bacterial growth to a certain extent. Furthermore, by setting a controllable ventilating window at the front end of the absorbent core, when the ventilating window is opened, the absorbent core is adjusted to a suitable position by controlling the flexible and malleable fixing strip, thereby forming a breathable channel between the absorbent core and the user, allowing full contact with the outside air and preventing the growth of anaerobic bacteria. This solves the problem of traditional sanitary pants causing stuffiness and bacterial growth after prolonged use, and makes postpartum women more comfortable while avoiding stuffiness.
