Description

Technical Field

[0001] The utility model relates to the technical field of disposable sanitary products, in particular to an elastic T-shaped diaper. Background Art

[0002] As a disposable sanitary product, diapers are mainly used to prevent leakage of baby excrement, can keep babies sleeping soundly all night, and have the characteristics of convenient use. They have been widely used in daily life. Most existing diapers have good water absorption. However, since diapers move with the movement of infants and young children, side leakage is likely to occur. In particular, the leak-proof function of existing diapers mostly depends on leak-proof gussets, which form a wrapping structure when standing up during wearing. However, only setting leak-proof gussets is difficult to ensure stability, and there is still a high possibility of side leakage.

[0003] Chinese Patent Publication No.: CN203885725U discloses a comfortable diaper, which includes a front elastic waistband, a rear elastic waistband, an absorbent pant body and leg guards. The absorbent pant body is composed of an upper hydrophilic non-woven fabric, an absorbent core body wrapped by wet strength paper and a bottom PE breathable leak-proof film. The absorbent core body has a pair of hollowings symmetrical to the axis of the core body. The rear elastic waistband is also connected with a hip wrapping structure, and the hip wrapping structure is semi-circular, and its edge is provided with elastic bands. Under the combined action of the elastic waistband and the hip wrapping structure, this patent is more fitting when worn, does not affect breathability and leg movement, has better breathability, is not easy to cause red buttocks, and saves materials at the same time. However, when this patent is used, the crotch becomes narrow, and when the baby moves or the urine volume is large, urine is easy to leak laterally, and its leak-proof performance is poor. Summary of the Utility Model

[0004] Therefore, in view of the above problems, the utility model provides an elastic T-shaped diaper, which solves the technical problem of poor leak-proof performance of existing T-shaped diapers.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

[0006] An elastic T-shaped diaper includes a diaper body, and the diaper body includes a liquid-permeable surface layer, an absorbent core layer and a liquid-impermeable bottom layer arranged in sequence from top to bottom. The front and rear ends of the diaper are provided with a front waistband and a rear waistband, and a magic tape and an adhesive part are respectively arranged on the front waistband and the rear waistband. The absorbent core layer is externally coated with an elastic fiber layer. First convex strips are arranged on both sides of the liquid-permeable surface layer along the length direction, and a plurality of second convex strips are arranged between the two first convex strips along the length direction. The first convex strips are higher than the second convex strips, and diversion grooves are formed between adjacent first convex strips and second convex strips and between adjacent two second convex strips.

[0007] Furthermore:

[0008] On both left and right sides of the liquid-permeable surface layer, there are arc-shaped first anti-leakage strips, and on the upper and lower ends of the liquid-permeable surface layer, there are strip-shaped second anti-leakage strips.

[0009] On the outer side of the first anti-leakage strip, there is an elastic rubber band, and the elastic rubber band is located 2 mm to 3 mm from the edge of the first anti-leakage strip.

[0010] On both sides of the diaper body, there are pleated anti-leakage edges.

[0011] The elastic fiber layer is made of spandex fiber.

[0012] The liquid-impermeable bottom layer includes a water-repellent non-woven fabric and a PE film provided at the lower end of the water-repellent non-woven fabric.

[0013] On the PE film, there are a plurality of neatly arranged through holes.

[0014] The absorbent core layer includes a fluff pulp layer and a superabsorbent polymer layer arranged in sequence from top to bottom.

[0015] The liquid-permeable surface layer is made of pure cotton non-woven fabric.

[0016] On the front waistband, there are a plurality of ventilation holes, and on the rear waistband, there is a waistband rubber band.

[0017] By adopting the foregoing technical solutions, the beneficial effects of the present utility model are as follows:

[0018] When the present utility model is in use, urine will flow along the first convex strip and the second convex strip to the diversion groove, and then disperse evenly in the front and rear directions along the diversion groove, keeping the liquid-permeable surface layer dry and breathable, preventing urine from leaking along the thighs, improving the urine absorption efficiency, and effectively avoiding backflow caused by excessive local liquid absorption of the absorbent core layer. Since the height of the first convex strip is higher than that of the second convex strip, the first convex strip fits the skin during use, preventing the diaper body from shifting and preventing urine from leaking along the thigh side. There is a certain gap between the second convex strip and the skin, and urine will not adhere to the skin, maintaining the breathability and comfort of infants during use. At the same time, the elastic fiber layer has good ductility, can effectively disperse and carry more urine, avoid leakage, and also make the absorbent core layer have good fit; further, the first anti-leakage strip prevents urine from leaking sideways, and the second anti-leakage strip prevents urine from leaking forward and backward, enhancing the anti-leakage performance of the diaper body; further, when in use, the rubber band forms an anti-leakage perimeter, reducing the risk of urine penetration; further, the pleated anti-leakage edge can improve the fit, has good wrapping property, and enhances the ability to block urine; further, the water-repellent non-woven fabric and the PE film have good waterproofness and durability, effectively preventing urine from passing through; further, the through holes and ventilation holes can improve the overall breathability; further, the pure cotton non-woven fabric has a comfortable touch and is soft and skin-friendly.
