Description
Technical Field
[0001] This utility model relates to the field of diaper technology, and in particular to an enhanced leak-proof diaper. Background Technology
[0002] Diapers are disposable hygiene products designed specifically for infants and people with limited mobility. Their core structure includes a top layer, an absorbent layer, and a bottom layer. The top layer is often made of skin-friendly materials to ensure softness and comfort when in contact with the skin, reducing friction and irritation. The absorbent layer contains superabsorbent polymers that quickly absorb and lock in urine, preventing backflow and resulting in damp skin. The bottom layer is made of a waterproof and breathable membrane to prevent leakage while wicking away heat and moisture. Their main function is to replace traditional cloth diapers, providing a convenient solution for waste disposal, helping users keep their skin dry and clean, and reducing the likelihood of diaper rash and other skin problems. They are especially suitable for people who cannot control their urination and defecation, significantly improving care efficiency and quality of life. Diapers are mainly divided into two categories: infant diapers and adult care diapers.
[0003] These enhanced leak-proof diapers are specifically designed for leak-prone situations. They achieve high-efficiency protection through a multi-technology structure, with the core features being a 3D protective barrier and a double leak-proof edge design. The 3D protective barrier wraps around the waist and groin, closely conforming to the body's curves like a flexible dam to prevent side leakage. The double leak-proof edge is made of highly elastic material, stretching flexibly with body movements to maintain a seal even during vigorous movement. However, without proper leak-proof measures, frequent changes may be necessary. With technological advancements, the leak-proof mechanism is a key line of defense for keeping the diaper dry. It consists of a 3D protective barrier, double leak-proof edge, and a diversion system. The 3D protective barrier typically uses highly elastic material to closely conform to the body's curves, acting like a flexible dam to prevent urine leakage even during vigorous movement. The double leak-proof edge is located on both sides of the crotch, with a soft inner layer that conforms to the skin and an outer layer that forms a physical barrier. Through the synergistic effect of the inner and outer layers, side leakage is effectively prevented. However, when there is excessive urine, it can easily leak through the side gaps, affecting the diaper's effectiveness. Utility Model Content

At this time, it will be absorbed by the multiple absorbent holes on the absorbent cloth. Meanwhile, the blocking strips and locking posts on both sides are locked inside the main body, which can block the urine in the main body, thereby enhancing the overall leak-proof effect of the diaper.
[0023] 2. In this utility model, when it is necessary to adjust the tightness of the diaper, first pull the adhesive cloth outward. At this time, the adhesive cloth will cause the hook to flip outward. Then pull the connecting strip. At this time, the connecting strip will cause the sliding block to slide along the inside of the long hole until it is adjusted to a suitable position, thus realizing the function of adjusting the overall tightness of the diaper.

The front part of the L-shaped hook 602 is fixedly connected to the rear part of the elastic cloth 501 to ensure that the two will not be displaced relative to each other during use. The outer wall of the L-shaped hook 602 has a square hole 601, which can slide with the outer wall of the L-shaped hook 602, thereby making the buckle assembly 6 more flexible and adaptable during use. A soft pad 7 is fixedly connected to the bottom of the main body 1 near the middle position, ensuring that it can play a good protective role and provide a more comfortable experience during use.
[0042] Working principle: After the main body 1 is put on, when urine is produced inside, it will flow along the guide groove 202 on the guide cloth 201 to the absorbent cloth 203 on both sides. At this time, it will be absorbed through the multiple absorbent holes 204 on the absorbent cloth 203. Meanwhile, the blocking strips 2052 and the retaining posts 2053 on both sides are locked inside the main body 1, which can block the urine in the main body 1. At the same time, the sponge pad 2051 can increase the overall comfort and achieve the effect of enhancing the overall leak prevention of the diaper.
[0043] When adjusting the tightness of the diaper, first pull the adhesive cloth 3041 outward. At this time, the adhesive cloth 3041 will cause the hook surface 3042 to flip outward. Then pull the connecting strip 301. At this time, the connecting strip 301 will cause the sliding block 8 to slide along the inside of the long hole 303 until it is adjusted to the appropriate position. Then stick the adhesive cloth 3041 and the hook surface 3042 together. Then fasten the square hole 601 onto the L-shaped hook 602, which realizes the function of adjusting the overall tightness of the diaper.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
