Detailed ways

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

A disposable adult diaper as shown in Fig. 1, Fig. 2 and Fig. 3 includes an outer cover 1, an absorber 2, a magic button 3, a leak-proof retaining wall 4 and elastic elastic bands 5 on legs, and the absorber 2 is located in the outer cover 1 Inside, the magic buckle 3, the leak-proof retaining wall 4 and the leg elastic rubber band 5 are arranged on the outer cover 1. The middle part of the outer cover 1 in the length direction and both sides in the width direction are provided with concave arc-shaped openings, and the middle part of the absorber 2 in the length direction and both sides in the width direction are provided with concave arc-shaped gaps. During use, the middle part of the lengthwise direction of the outer cover 1 corresponds to the crotch of the human body, the rear portion of the lengthwise direction of the outer cover 1 corresponds to the back waist of the human body, and the front portion of the lengthwise direction of the outer cover 1 corresponds to the front waist of the human body.

Outer cover 1 comprises impermeable outer layer 12 and water-permeable inner layer 11, and in thickness direction, impermeable outer layer 12 is the lower part, and water-permeable inner layer 11 is upper part, and impermeable outer layer 12 is made of water-repellent base film 121 and without The woven fabric 122 is a composite structure, and the water-repellent base film 121 is located on the top of the non-woven fabric 122 in the thickness direction. The water-permeable inner layer 11 is a hydrophilic non-woven fabric.

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 Both are located in the middle of the first absorbent core 21 , and the absorbent body 2 is provided with a diversion groove 23 , and the water absorption 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.

The absorber 2 is divided into a central area 231, a connecting area 232 and a side area 233 from the width direction, the central area 231 is located in the middle of the width direction of the absorber 2, the connecting area 232 and the side area 233 are two, two The side region 233 is at the outer end of the width direction, and each connecting region 232 is between the central region 231 and the side region 233, and the shape of the guide groove on the central region 231 and the side region 233 is rhombus, and the connection region 232 The shape of the diversion groove is a straight strip that runs through the absorber along the length direction; the shape of the absorber 2 is left-right symmetrical along the center line along the length direction. One function of the diversion groove 23 is to enhance the strength of the absorber 2. At the same time, the rhombus-shaped diversion groove on the central area 231 can be used for the urine to quickly spread around, and the diversion groove in the connecting region 232 is used to guide the urine. The liquid diffuses in the length direction, and prevents the urine inside the connection area 232 in the width direction from diffusing to the outside of the connection area 232 as far as possible, thereby achieving the effect of preventing side leakage.

In the thickness direction, the upper end of the leak-proof retaining wall 4 is provided with a retaining wall elastic 41, and the lower end of the leak-proof retaining wall 4 is bonded and fixed to the hydrophilic non-woven fabric by glue. The middle part can be separated from the surface of the hydrophilic non-woven fabric, and the front and rear ends of the length direction of the upper end of the leak-proof retaining wall 4 are fixed with the surface of the hydrophilic non-woven fabric. The height between the upper end and the lower end of the leak-proof retaining wall 4 is 25-50mm, and the glue bonding line fixed between the lower end of the leak-proof retaining wall 4 and the hydrophilic non-woven fabric is inwardly curved from the length direction, that is, in the length direction , the height of the leak-proof retaining wall 4 at the front and rear ends is higher than the height of the leak-proof retaining wall 4 in the middle.

There is a gap of at least 3 mm between the lower end of the leak-proof retaining wall 4 and the fixed part of the hydrophilic non-woven fabric and the outside of the absorber 2 in the width direction, and the gap is not greater than 30 mm. 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 leaking is still about 10%; the gap is more than 3mm, and the probability of seepage is less than 1% when the urine volume is large. Compared with the traditional fixed structure of leak-proof retaining wall, the problem of easy seepage of the absorber is basically solved; The gap above is not greater than 30mm, otherwise it will affect the overall design of the product, especially the comfort of use.

In the width direction, a water-repellent non-woven fabric 42 is provided on the outside of the leak-proof retaining wall 4, and the water-repellent non-woven fabric 42 and the water-repellent bottom film 121 are fixed by glue, so it is less likely to seep.

At the arc-shaped notch of the body 2 and the concave notch of the toilet paper 8, the outer side in the width direction of the concave notch of the toilet paper 8 is more outward than the outer side in the width direction of the arc-shaped notch of the absorber 2; and from the width direction, The lower end of the leak-proof retaining wall 4 and the fixing part of the hydrophilic non-woven fabric are on the outside of the concave gap of the toilet paper 8, and the lower end of the leak-proof retaining wall 4 and the fixing part of the hydrophilic non-woven fabric are in the width direction of the concave gap of the toilet paper 8. There is a gap of at least 2mm between the outer sides. The end of the absorber 2 in the length direction and the end in the width direction are all connected by arc lines, and the four end angles of the toilet paper 8 are all right angles, that is, viewed from the top to the bottom in the thickness direction, from the width direction, the four corners of the toilet paper 8 are right angles. Two end corners are exposed outside the four ends of the absorber 2, which facilitates the traction effect of the toilet paper 8 on the absorber 2 during production. Traditional toilet paper is rectangular, and the width is slightly larger than the absorber. The toilet paper of this patent is provided with concave gaps on both sides. In the production process, the rectangular toilet paper is placed first, and the gaps on both sides of the toilet paper 8 are cut off before bonding and fixing. A gap is partially formed, and one advantage is that the thickness of the outer cover 1 near the arc-shaped gap can be reduced. The arc-shaped gap of the outer cover 1 directly corresponds to the crotch of the human body, and it is close to the inner thigh during use. Another advantage is to prevent the toilet paper 8 from passing through the bonding and fixing place of the lower end of the leakproof retaining wall 4 and the hydrophilic nonwoven fabric in the width direction, while limiting the lower end of the leakproof retaining wall 4 and the hydrophilic nonwoven fabric. There is a gap of at least 2mm between the fixing point and the outside in the width direction of the toilet paper 8, which can better prevent the occurrence of liquid seeping through the toilet paper 8 to the outside at the crotch.
