[0056] Compared with the previous symmetrical design of the front and back areas, the asymmetrical design increases the coverage area of ​​the hip-wrapped sanitary pants on the hips by at least 20%.

[0057] In some specific implementations, both side ends of the rear area are respectively connected to both side ends of the front area to form a connection area 4, and the connection area 4 is located at the front abdomen of the human body.

[0058] The front end, rear end and middle part of the absorbent sheet 2 are fixed on the trouser-type outer garment 1, and the front end and rear end of the absorbent sheet 2 are respectively perpendicular to the elastic band of the front abdominal area B and the elastic band of the rear abdominal area D;

[0059] The elastic band in the overlapping area between the rear end of the absorbent sheet 2 and the rear abdominal area D is cut and de-stretched to ensure the flatness of the rear end of the absorbent sheet 2, so that the rear end of the absorbent sheet 2 can fit better with the buttocks, reduce the risk of menstrual blood flowing backwards along the crotch during sleep at night, and reduce the risk of posterior leakage. At the same time, this design can also increase the covering area of ​​the absorbent sheet 2 on the buttocks.

[0060] If necessary, the elastic band in the overlapping area between the front end of the absorbent sheet 2 and the front abdominal area B can also be cut to eliminate the elasticity.

[0061] A central convex cotton core 3 may be provided in the middle of the absorbent sheet 2. The amount of cotton at the central convex cotton core 3 under the same area may be greater than or equal to 1.5 times the amount of cotton at other positions on the absorbent sheet 2 except the central convex cotton core 3. In this way, density gradients in different regions may be formed on the absorbent sheet 2. When absorbing and storing menstrual blood, the menstrual blood may be diffused and guided simultaneously, thereby reducing the risks of front-back leakage and side leakage of menstrual blood.

[0062] In some specific implementations,

[0063] The absorbent sheet 2 is provided with three pressing areas, including a middle area and two side areas. The two side areas are symmetrically distributed with respect to the middle area. The position of the middle area corresponds to the position of the central convex cotton core 3 .

[0064] In some specific implementations, the middle area and the side area are both provided with a plurality of prismatic embossings, and the prismatic embossings in the middle area and the side area can both be designed with two vertices arranged horizontally and two vertices arranged vertically, the distance between the two vertices arranged horizontally in the middle area is W2, W1 is less than or equal to 2 times of W2, and the distance between the two vertices arranged vertically is L2; ​​the distance between the two vertices arranged horizontally in the side area is W3, W is greater than or equal to the sum of W1 and 4 times of W3, and the distance between the two vertices arranged vertically is L3; wherein

[0065] The length L1 of the central convex cotton core can be 210mm, and the width W1 can be less than or equal to 40mm; the width W of the absorbent sheet can be greater than 60mm and less than or equal to 135mm; W2 can be 20mm, L2 can be 16mm, W3 can be 10mm, L3 can be 8mm, and the pressing point can be a round point with a diameter of 2mm. There are 8 pressing points on the prismatic embossing in the middle area, 4 of which can be directly set on the four vertices of the prismatic embossing in the middle area, and the other 4 pressing points can be set on the center point of the edge of the prismatic embossing; there are 4 pressing points on the prismatic embossing in the side area, and the 4 pressing points can be directly set on the four vertices of the prismatic embossing in the side area.

[0066] In some specific implementations, an elastic waist group can be added to the side of the hip-wrapped sanitary pants close to the human body. The elastic waist group includes a front elastic waist group 401 and / or a rear elastic waist group 402. The elastic waist group is placed at the junction of the front and / or rear ends of the inner garment and the pants-type outer garment 1, and is located at the topmost layer (i.e., on the side closest to the human body). The elastic waist group is elastic, and the length of the elastic waist group is smaller than the length of the corresponding front waist area A and / or rear waist area E, and the length of the elastic waist group is larger than the width W of the absorbent sheet 2. Taking the elastic waist group including the front elastic waist 401 and the back elastic waist 402 as an example, the front elastic waist 401 is placed at the overlap between the front end of the inner garment and the trouser-type outer garment 1, and the back elastic waist 402 is placed at the overlap between the back end of the inner garment and the trouser-type outer garment 1. The front elastic waist 401 and the back elastic waist 402 are both placed at the uppermost layer, so that the overlap between the inner garment and the trouser-type outer garment is elastic, the length L6 of the front elastic waist 401 is less than the length L4 of the front waist region A, the length L7 of the back elastic waist 402 is less than the length L5 of the back waist region E, and both L6 and L7 are greater than W. In the manufacturing process, it is in a tensioned state. After the manufacturing is completed, the overlap between the inner garment and the trouser-type outer garment shrinks under the elastic action of the front elastic waist 401 and the back elastic waist 402. During the use of the product, this place can shrink naturally close to the body, further playing a role in preventing front and back leakage. The area 411 of the front elastic waist 401 that does not overlap with the inner garment and the area 421 of the back elastic waist 402 that does not overlap with the inner garment can be treated with de-elasticity to ensure that the areas of the front elastic waist 401 and the back elastic waist 402 that overlap with the inner garment have elasticity. The area 411 of the front elastic waist 401 that does not overlap with the inner garment and the area 421 of the back elastic waist 402 that does not overlap with the inner garment do not have elasticity but use the elasticity of the front waist area A and the back waist area E, thereby ensuring the effect of preventing leakage from the front and the back while ensuring wearing comfort.

[0067] The above undisclosed matters can be directly implemented by using existing technologies, so they will not be elaborated here.

[0068] The above are only some preferred embodiments of the present invention. It should be pointed out that a person skilled in the art can make several similar modifications and improvements without departing from the inventive concept of the present invention, and these should also be regarded as the protection scope of the present invention.
