Description

Technical Field

[0001] This utility model relates to the field of diaper technology, and in particular to a diaper with a fast-absorbing core. Background Technology

[0002] Disposable diapers are disposable hygiene products made of materials such as non-woven fabric, super absorbent polymer (SAP), and PE film. Their core function is to absorb and lock in urine, keeping the user's skin dry and preventing clothing or bedding from getting soiled.

[0003] Patent CN216257824U discloses a diaper. It includes a diaper body and a warming element. The diaper body comprises a front waistband, a crotch area, and a back waistband, with the crotch area connecting the front and back waistbands. The front waistband has a layer containing the warming element. Using this patent, urine can be discharged towards the absorbent core under the protection of the first and second leak-proof side panels, forming an absorbent area in the crotch area. However, the aforementioned prior art lacks a flow-guiding structure, preventing urine from quickly diffusing from the contact point to the absorbent core, causing liquid to concentrate in a certain area and reducing overall absorption efficiency.

[0004] Therefore, there is a need to provide a diaper with a fast-absorbing core. Utility Model Content

[0005] To overcome the shortcomings of existing patents that lack a flow-guiding structure, which prevents urine from quickly diffusing from the contact point to the absorbent core and causes liquid to concentrate in a certain area, thus reducing the overall absorption efficiency, this utility model provides a diaper with a fast-penetration absorbent core. Through structures such as a flow-guiding layer, flow-guiding holes, and a skin-friendly layer, urine can be quickly penetrated and absorbed, avoiding leakage.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a diaper with a fast-penetrating absorbent core, comprising a diaper body, a PE leak-proof layer, a first absorbent layer, and a second absorbent layer. The diaper body is provided with a PE leak-proof layer, the leak-proof layer is provided with a first absorbent layer, the first absorbent layer is provided with a second absorbent layer, and the diaper also includes a diversion layer and a skin-friendly layer. The second absorbent layer is provided with a diversion layer, the diversion layer having multiple diversion holes, and the diversion layer being provided with a skin-friendly layer.

[0007] Preferably, the diaper also includes female and male hook and loop fasteners, with two female hook and loop fasteners and two male hook and loop fasteners on the diaper body.

[0008] Preferably, it also includes a first extension fabric piece, a fastener, a second extension fabric piece, and a rivet. The male Velcro has the first extension fabric piece, and the female Velcro has the second extension fabric piece. The first extension fabric piece has a fastener, and the second extension fabric piece has a rivet.

[0009] Preferably, it also includes a breathable layer, with two breathable layers provided on the diaper body.

[0010] Preferably, it also includes elastic bands, with two elastic bands provided on the diaper body.

[0011] As a preferred option, the skin-friendly layer has multiple through-holes.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By expanding the liquid contact area through the trapezoidal flow holes of the flow guiding layer, the urine can be accelerated to penetrate downwards, avoiding surface liquid retention, thereby achieving rapid penetration function, avoiding liquid accumulation in local areas, and reducing the risk of side leakage or back leakage.

[0013] 2. By folding the diaper body, the two male Velcro straps and two female Velcro straps are glued together, thereby achieving waist tightness adjustment to adapt to different body shape needs.

[0014] 3. By attaching the first extension fabric piece to the second extension fabric piece and securing the rivet in the rivet buckle, additional fixing points are provided to enhance the adhesion and prevent the Velcro from coming loose during movement. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1: A diaper with a fast-absorbing core, see reference. Figures 1-5 As shown, the diaper includes a diaper body 1, a PE leak-proof layer 2, a first absorbent layer 3, and a second absorbent layer 4. The PE leak-proof layer 2 is located in the middle of the diaper body 1. The first absorbent layer 3 is located on top of the PE leak-proof layer 2. The second absorbent layer 4 is located on top of the first absorbent layer 3. The diaper also includes a diversion layer 5 and a skin-friendly layer 6. The diversion layer 5 is located on top of the second absorbent layer 4. The diversion layer 5 has multiple diversion holes 501 evenly spaced on it. The cross-section of the diversion holes 501 is trapezoidal. The skin-friendly layer 6 for contacting the skin is located on top of the diversion layer 5.

[0023] See Figure 1 , Figure 3 and Figure 5 As shown, it also includes a breathable layer 13, and the diaper body 1 has breathable layers 13 on both the front and back.

[0024] See Figure 2 and Figure 3 As shown, the skin-friendly layer 6 has multiple through holes to ensure that urine can quickly seep into the layers below during use.

[0025] When using this diaper, place it over the baby's crotch so that the skin-friendly layer 6 and the breathable layer 13 come into contact with the baby's skin. The skin-friendly layer 6 is made of soft, non-irritating material, while the breathable layer 13 promotes air circulation, expels heat and moisture, and reduces the risk of rashes. When the diaper absorbs urine, the urine first comes into contact with the skin-friendly layer 6 and is further facilitated to pass through its perforations, reducing skin contact time and keeping the baby dry. When urine seeps into the diversion layer 5, the trapezoidal diversion holes 501 of the diversion layer 5 expand the liquid contact area, accelerate the downward penetration of urine, and prevent surface liquid retention, thereby achieving rapid penetration and preventing liquid from accumulating in local areas, reducing the risk of side or back leakage. Finally, the urine is absorbed by the gradient absorption structure formed by the first absorbent layer 3 and the second absorbent layer 4, achieving efficient water retention, and the PE anti-leakage layer 2 prevents liquid leakage.

[0026] Example 2: Based on Example 1, see [link to example]. Figure 1 and Figure 5 As shown, it also includes male hook and loop fasteners 7 and female hook and loop fasteners 8. The female hook and loop fasteners 8 are symmetrically arranged on the left and right sides of the front part of the diaper body 1, and the male hook and loop fasteners 7 are symmetrically arranged on the left and right sides of the rear part of the diaper body 1.

[0027] See Figure 1 and Figure 5As shown, it also includes a first extension fabric piece 9, a fastener 10, a second extension fabric piece 11, and a rivet 12. The male Velcro 7 is provided with the first extension fabric piece 9, and the female Velcro 8 is provided with the second extension fabric piece 11. The top of the first extension fabric piece 9 is provided with a fastener 10, and the bottom of the second extension fabric piece 11 is provided with a rivet 12.

[0028] See Figure 1 As shown, it also includes elastic bands 14, with elastic bands 14 provided on both the left and right sides of the middle part of the diaper body 1.

[0029] When it is time to put on the diaper, first lay the diaper body 1 flat, then place the baby on the diaper body 1 and fold the diaper body 1 so that the two male Velcro straps 7 and the two female Velcro straps 8 are attached to each other, thereby achieving waist tightness adjustment to adapt to different body shape needs. The first extension fabric 9 and the second extension fabric 11 are attached together, and the rivet 12 is locked in the buckle 10, which provides additional fixing points, enhances the adhesion, and prevents the Velcro from coming loose during activities. The elastic band 14 forms an elastic contraction at the waist and leg circumference, conforming to the body curve, preventing side leakage and avoiding marks, and improving wearing comfort.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
