DETAILED DESCRIPTION

[0026] The following is combined with Figures 1 to 6 The implementation methods of the present invention are described with relevant embodiments, but the implementation methods of the present invention are not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as the known technology in this technical field and can be known and mastered by the technicians in this technical field.

[0027] The absorption performance of absorbent products is often the most important point, but many absorbent products use the method of increasing the absorption core or increasing the number of absorption core layers to improve the absorption performance of absorbent products. This method easily reduces the air permeability of absorbent products, resulting in a feeling of stuffiness and humidity during use. The setting of slots can balance the high absorption performance and air permeability of absorbent products. More specifically, slots can accelerate the entry of liquid into the absorption layer and improve the absorption efficiency. At the same time, slots allow air to circulate more smoothly, which helps to improve the air permeability of absorbent products.

[0028] The utility model provides an absorbent product with multi-region grooves, such as Figure 1 As shown, the absorbent article comprises a body having a longitudinal direction corresponding to the front-back direction of the wearer and a transverse direction orthogonal thereto, such as Figure 5 and Figure 6 As shown, the body includes a surface layer 1 arranged at the top, a bottom layer 4 arranged at the bottom, and a guide layer 3 and an absorbent layer 4 arranged between the surface layer 1 and the bottom layer 4. At the same time, the body is divided into a front end area 51, a middle end area 52 and a rear end area 53 in sequence along its longitudinal direction. The front end area 51 is provided with a first slot 511 penetrating the surface layer 1 and the guide layer 3, the front end area 51 and the rear end area 53 are respectively provided with a second slot penetrating the guide layer 3 and the absorbent layer 4, the middle end area 52 is provided with a third slot 521 penetrating the surface layer 1, and the rear end area 53 is provided with a fourth slot 531 penetrating the surface layer 1 and the guide layer 3, and the bottom end of the fourth slot 531 extends into the absorbent layer 4.

[0029] The utility model divides the absorbent product into a front end area 51, a middle end area 52 and a rear end area 53, and arranges slots of different shapes and different three-dimensional degrees according to different areas. The slots can make the liquid begin to absorb, achieve more efficient absorption of liquid, increase the dryness and air permeability of the product, and the arrangement of the slots further increases the air permeability of the product. At the same time, the arrangement of the slots in divided areas can ensure rapid absorption of liquid while avoiding damage to the continuity of the material, thereby ensuring that the stability and strength of the overall structure are not damaged.

[0030] In order to make the middle end area 52 more likely to come into contact with liquid, the utility model arranges a third groove 521 penetrating the surface layer 1 in the middle end area 52 to increase the absorption speed of the middle end area 52, so that the liquid in the middle end area 52 can quickly enter the guide layer 3 through the third groove 521 and diffuse along the guide layer 3 to the front end area 51 and the rear end area 53. The middle end area 52 is in contact with more liquid than the other two areas. The third groove 521 can reduce the residence time of the liquid in the surface layer 1, thereby keeping the surface layer 1 of the product dry.

[0031] In view of the different volumes of liquid in contact with the front end area 51 and the rear end area 53, the front end area 51 is provided with a first groove 511 penetrating the surface layer 1 and the guide layer 3, so that a part of the liquid can quickly enter the absorption layer 4 through the first groove 511 to efficiently absorb the liquid, and the other part of the liquid can continue to diffuse longitudinally along the guide layer 3; the front end area 51 and the rear end area 53 are respectively provided with a second groove penetrating the guide layer 3 and the absorption layer 4, and the liquid absorbed by the surface layer 1 in the front end area 51 and the rear end area 53 and the liquid diffused in the middle end area 52 can quickly enter the absorption layer 4 through the second groove, thereby improving the absorption efficiency, and can also effectively reduce the residence time of the liquid and reduce the risk of reverse osmosis.

[0032] In addition, the utility model provides a fourth groove 531 near the edge of the rear end area 53, the fourth groove 531 penetrates the surface layer 1 and the guide layer 3 and the bottom end extends into the absorption layer 4, the liquid in the surface layer 1 can directly enter the absorption layer 4 quickly through the fourth groove 531, and the fourth groove 531 is provided to prevent leakage from the back when the user lies flat.

[0033] As one of the preferred embodiments of the present invention, Figure 2 and Figure 3 As shown, the length directions of the first slot 511, the second slot and the fourth slot 531 are respectively arranged along the transverse direction of the main body, and the length direction of the third slot 521 is arranged along the longitudinal direction of the main body. There are a plurality of first slots 511, the second slots, the third slots 521 and the fourth slots 531, respectively, and the plurality of first slots 511, the second slots, the third slots 521 and the fourth slots 531 are respectively arranged and distributed along the direction perpendicular to their own length directions.

[0034] The transversely arranged grooves pay more attention to the transverse diffusion of the liquid. It can guide the liquid from the concentrated area in the middle to a wider area, so that the hygroscopic area of ​​the absorbent product can distribute the liquid more evenly. It helps to balance the hygroscopic load of each part of the absorbent product and improve the overall liquid absorption performance. At the same time, the transverse grooves can also increase the air permeability and comfort of the absorbent product and reduce the feeling of dampness. The third groove 521 arranged longitudinally can quickly guide the liquid to flow in the longitudinal direction, and cooperate with the longitudinal diffusion of the guide layer 3 to help the liquid quickly penetrate into the absorbent core. The longitudinally arranged grooves can ensure that the liquid is effectively absorbed and distributed to a wider area, reducing the possibility of accumulation on the surface, thereby reducing the risk of reverse osmosis.

[0035] At the same time, the slots of the utility model are arranged and distributed in a direction perpendicular to their own length direction to avoid damage to the continuity of the material, and the transverse slots are arranged at the longitudinal ends of the longitudinal third slots 521 to prevent the direction and position of the slots from being too dense and affecting the overall stability. The longitudinal slots can quickly guide the liquid into the absorption core, while the transverse slots can evenly distribute the liquid to a wider area. The combination of the two can achieve more efficient and uniform liquid management.

[0036] As one of the preferred embodiments of the present invention, Figure 3 and Figure 4 As shown, the second slot includes a second front slot 512 and a second rear slot 532. The second slot provided in the front end area 51 is the second front slot 512, and the second slot provided in the rear end area 53 is the second rear end slot 532. The second front slot 512 is provided on the side of the first slot 511 away from the middle end area 52, and the second rear end slot 532 is provided on the side of the fourth slot 531 close to the middle end area 52. Figure 3 and Figure 4 , combined with Figure 5 It can be seen that the depth and layer height of the second front end slot 512 and the second rear end slot 532 are the same.

[0037] According to the structure of the human body, in the areas divided by the present invention, the arrangement of the contact liquid from more to less should be the middle area 52> the front area 51> the rear area 53, so the middle area 52 is provided with a third slot 521 to accelerate the longitudinal flow and diffusion of the liquid. The third slot 521 allows the liquid in the middle area 52 to quickly enter the guide layer 3 through the third slot 521 and diffuse the front area 51 and the rear area 53 along the guide layer 3. The end of the front area 51 close to the middle area 52 is provided with a first slot 511 that accelerates both the longitudinal diffusion of the liquid and the efficient absorption of the liquid. The front area 51 and the rear area 53 are also provided with a second slot that accelerates the efficient absorption of the liquid. The liquid absorbed by the surface layer 1 in the front area 51 and the rear area 53 and the liquid diffused in the middle area 52 can quickly enter the absorption layer 4 through the second slot, thereby improving the absorption efficiency, and effectively reducing the residence time of the liquid and reducing the risk of reverse osmosis.

[0038] It is worth noting that the number of the second front end slots 512 is greater than the number of the second rear end slots 532, and the number of the third slots 521 is greater than the number of the second rear end slots 532. The middle end region 52 and the front end region 51 of the absorbent article are more likely to contact the liquid, so more slots are provided to increase the absorption area and speed. The rear end region 53 is less exposed to the liquid, and the number of slots is less than that of the middle end region 52 and the front end region 51 to maintain the stability and strength of the overall structure.

[0039] As one of the preferred embodiments of the present utility model, the first slot 511 and the second slot are symmetrically arranged along the longitudinal center axis of the body. Figure 4 As shown, the fourth slot 531 is arranged at the end of the rear end area 53 away from the middle end area 52 and close to the edge. The fourth slot 531 is composed of two groups of slots arranged alternately, and the two groups of slots extend along one end away from each other. The fourth slot 531 is arranged to prevent rear leakage when the user lies flat. When the user lies flat, the liquid flows to the rear end area 53 and quickly enters the absorbent layer 4 through the fourth slot 531. The two groups of slots arranged alternately in the fourth slot 531 can maintain the stability of the absorbent product and ensure that the fourth slot 531 can cover the lateral area of ​​the rear end area 53 to prevent liquid leakage.

[0040] As one of the preferred embodiments of the present utility model, the absorption layer 4 includes polymer absorbent particles 31 and a wrapping cloth that wraps the polymer absorbent particles 31. The wrapping cloth is divided into an upper wrapping layer 32 or a lower wrapping layer 33 according to whether it is located above or below the polymer absorbent particles 31. The polymer absorbent particles 31 are in a multi-layer stacked state in the wrapping cloth.

[0041] It is worth noting that when the polymer absorbent particles 31 are stacked in multiple layers, the secondary absorption is easily hindered. After the polymer absorbent particles 31 absorb water for the first time and swell, the internal structure and space of the particles are filled, making it difficult for new liquid to enter, hindering the liquid from contacting with the lower polymer absorbent particles 31. In order to prevent the polymer absorbent particles 31 from hindering the secondary absorption after the initial absorption and swelling, the second groove penetrates the upper wrapping layer 32, the polymer absorbent particles 31 and the lower wrapping layer 33, so that the liquid can directly enter the absorption layer 4 through the second groove, and the lower polymer absorbent particles 31 can also be directly in contact with the liquid. The fourth groove 531 penetrates the upper wrapping layer 32. The fourth groove 531 is to prevent the phenomenon of liquid leakage. This part of the liquid is relatively small, and the upper part of the polymer absorbent particles will not absorb and swell to hinder the lower part of the polymer absorbent particles 31 from contacting with the liquid. Therefore, it only needs to penetrate the upper wrapping layer 32 to allow the liquid to contact with the polymer absorbent particles 31.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
