Detailed ways

Below in conjunction with Fig. 1, Fig. 2 and Fig. 3, this patent is further explained.

Example 1

An adult diaper as shown in Figure 1 and Figure 3, including an outer cover 1, an absorber 2, a magic button 3, a leak-proof retaining wall 4, elastic elastic bands for legs 5 and a pair of rear connecting parts 8, the absorber 2 In the outer cover 1, the leak-proof retaining wall 4, the leg elastic elastic band 5 and a pair of rear connecting parts 8 are arranged on the outer cover 1, and the leak-proof retaining wall 4 and the leg elastic elastic band 5 are sequentially arranged on the width of the absorber 2 On the outside of the direction, the magic buckle 3 is fixed on the rear connecting portion 8 .

During use, the rear part of the length direction of the outer cover 1 corresponds to the back waist of the human body, the front part of the length direction of the outer cover 1 corresponds to the front waist of the human body, and the middle part of the length direction of the outer cover 1 corresponds to the crotch of the human body.

In the unfolded state, both the outer cover 1 and the rear connecting portion 8 are rectangular, and the outer cover 1 and a pair of rear connecting portions 8 are connected to form a T shape. The outer cover 1 includes a water-impermeable outer layer 12 and a water-permeable inner layer 11, the water-impermeable outer layer 12 is the lower part and the water-permeable inner layer 11 is the upper part in the thickness direction. The non-water-permeable outer layer 12 is composed of a water-repellent base film 121 and a bottom non-woven fabric 122. In the thickness direction, the water-repellent base film 121 is on the top of the bottom non-woven fabric 122, and the water-permeable inner layer 11 is a hydrophilic non-woven fabric.

In the width direction, each rear connecting portion 8 is divided into successively connected inner sheet 81, middle sheet 82 and outer sheet 83 from the inside to the outside, the inner sheet 81 is fixed on the outer cover 1, and the middle sheet 82 is laterally stretchable. Elastic stretch sheet, magic buckle 3 is fixed on the outer sheet 83. The magic buttons 3 on each outer sheet 83 are two arranged in parallel along the length direction. The magic buttons 3 include a fixed part 31 and a bonding part 32. The fixing part 31 is fixed on the outer sheet 83, and the bonding part 32 can be stretched. Out of the outside sheet 83.

In the thickness direction, the absorber 2 is composed of a first absorbent core 21 close to the water-repellent base film 121 and a second absorbent core 22 close to the hydrophilic non-woven fabric 11; in the length and width directions, the position of the second absorbent core 22 is They are all located in the middle of the first absorbent core 21 , and the absorbent body 2 is provided with diversion grooves, and the water absorption capacity of the second absorbent core 22 is greater than that of the first absorbent core 21 . In the thickness direction, a diversion layer 6 is provided between the second absorbent core 22 and the hydrophilic non-woven fabric 11, fully considering the factor that adults have a large amount of urine, and using the diversion layer 6 to guide the urine to the first absorbent core. On the core body 21 and the second absorbent core body 22, because the second absorbent core body 22 has a large water absorption capacity, it can alleviate the problem of rapid fluid accumulation in the middle of the absorbent body and improve the comfort of use.

In the thickness direction, the upper end of the leak-proof retaining wall 4 is provided with a retaining wall elastic 41, the lower end of the leak-proof retaining wall 4 is bonded to the hydrophilic non-woven fabric by glue, and the lower end of the leak-proof retaining wall 4 is connected to the hydrophilic non-woven fabric. There is a gap of at least 3 mm between the fixed place and the outer side of the absorber 2 in the width direction, and the gap is not greater than 20 mm. In the thickness direction, the middle part of the upper end of the leak-proof retaining wall 4 in the length direction can be separated from the surface of the hydrophilic non-woven fabric, and the front and rear ends of the upper end of the leak-proof retaining wall 4 in the length direction are fixed to the surface of the hydrophilic non-woven fabric, and the leak-proof retaining wall The height between the upper end and the lower end of the wall 4 is 25-50mm, and the effect of preventing side leakage is good. In the width direction, the outer side of the leakproof retaining wall 4 is provided with a water-repellent non-woven fabric 42 connected therewith, and in the thickness direction, the elastic elastic bands 5 of the legs are arranged between the water-repellent non-woven fabric and the non-water-permeable outer layer 12 Between the water-repellent non-woven fabric and the non-water-permeable outer layer 12, specifically the water-repellent base film 121 is bonded and fixed by glue, that is, the water-repellent non-woven fabric on the outside of the fixed part of the leak-proof retaining wall 4 and the width direction of the hydrophilic non-woven fabric. The cloth and the water-repellent base film 121 are bonded and fixed by glue, so lateral seepage is not easy to occur. The size of the above-mentioned gap is very critical. If the gap is less than 1mm, it is not only inconvenient to produce, but also the probability of leakage is about 20% when the urine volume is large; the gap is 1-2.5mm, and the probability of leakage is large when the urine volume is large. The probability of leakage is still about 10%; the gap is more than 3mm, and the probability of leakage is less than 1% when the urine volume is large. Compared with the traditional fixed structure of leak-proof retaining wall, it basically solves the problem that the absorber is easy to seepage laterally. Problem; the gap above is not greater than 20mm, otherwise it will affect the overall design of the product, especially the comfort of use.

The width of the front and rear parts of the absorber 2 in the longitudinal direction is greater than the width of the central part in the longitudinal direction of the absorber. In the length direction, the leg elastic elastic band 5 is straight, and the leg elastic elastic band 5 is parallel to the side in the length direction of the outer cover 1, which can reduce the size from the leakproof retaining wall 4 to the width edge of the outer cover 1 and reduce the production cost .

In the length direction, a water-repellent back waist retaining wall 7 is arranged at the rear of the absorber 2, and both ends of the water-repellent back waist retaining wall 7 are fixed between the hydrophilic non-woven fabric and the leak-proof retaining wall 4, and the water-repellent back waist The rear side of the retaining wall 7 is fixed with the hydrophilic non-woven fabric, and the front side of the water-repellent rear waist retaining wall 7 is provided with a rear elastic rubber band 71, and the front side of the water-repellent rear waist retaining wall 7 can be separated from the surface of the hydrophilic non-woven fabric. The water-repellent rear waist retaining wall 7 can effectively prevent the problem of urine leakage backwards, especially for long-term bedridden use, the effect of preventing rear side leakage is better.

The length of cover 1 is 700-1200mm, the width of cover 1 is 250-400mm; the length of absorber 2 is 630-800mm, the minimum width of absorber 2 is 150-200mm, and the maximum width of absorber 2 is 300-400mm; the width of magic buckle 3 is 20-50mm, the distance between the two magic buttons 3 arranged in parallel along the length direction is 30-120mm; the length of the rear connecting part 8 is 200-300mm, and the width is 200-350mm.

Example 2

As shown in Figure 2 and Figure 3, a pair of front side connecting parts 88 are added on the basis of Embodiment 1, and the pair of front side connecting parts 88 are fixed on the front side in the length direction of the outer cover, and the front side is connected The portion 88 is rectangular, the length of the front connecting portion 88 is 200-300mm, and the width is 200-350mm. The outer cover 1 , the pair of front connecting parts 88 and the pair of rear connecting parts 8 are connected in an I-shape.

The above-mentioned two embodiments are only preferred embodiments of this patent. For example, the front portion of the bottom non-woven fabric 122 in the length direction is also provided with a front waist sticker matching the Velcro 3; The middle part is arc-shaped to replace the straight leg elastic elastic band 5 in Embodiment 1, and the front and rear parts of the elastic elastic band of the leg are more outside in the width direction than the middle part of the elastic elastic band of the leg, and the use comfort is better. .
