Description
Technical Field
The invention relates to the field of sanitary products, in particular to non-woven fabric menstrual period pants capable of preventing back leakage.
Background
The menstrual period trousers are underpants specially for women to wear in the physiological period, the most different point of the structure of the conventional menstrual period trousers from that of the common underpants is that the menstrual period trousers are made of cloth (such as nylon cloth) which is difficult to absorb water and permeate in the crotch part and the back area or made of cloth which is subjected to anti-seepage treatment, and when menstrual blood leaks from sanitary cotton adhered to the inner surface of the menstrual period trousers, the menstrual blood can be prevented from permeating outwards to contaminate the outer skirt or trousers of the women, so that embarrassment and embarrassment are caused.
As for the structure of conventional menstrual pants, there is referred to a pants-type sanitary napkin described in chinese patent publication No. CN104257458A, which comprises an absorbent main body having a skin sheet and an absorber; a front waistband member disposed in the front waistband region; a rear waistband member disposed in the rear waistline region; an outer joint section formed by joining an outer edge of the front waistband member and an outer edge of the rear waistband member; a compressing part which compresses the skin surface sheet and the absorber along the thickness direction. The compression section has a pair of excretion section compression sections extending in the front-rear direction at positions on both outer sides in the width direction than excretion section opposing sections disposed so as to face the excretion section of the wearer, and the center in the front-rear direction of the excretion section compression section is located on the front side of the center in the front-rear direction of the sanitary napkin in the crotch region. In the menstrual pants with the structure, the excretory opening compression part (namely the embossing diversion part in the scheme) is less in the rear crotch part area of the sanitary towel and is mainly concentrated in the front crotch part of the sanitary towel. When a woman sleeps at night by using the product, the less excretory opening compression part of the rear crotch part is difficult to play good drainage absorption and flow blocking buffer effects, and the problem that menstrual blood leaks from the rear end of menstrual trousers is easy to occur.
In addition, refer to the bacteriostatic and antiallergic menstrual period pants with a dumbbell type absorption core, which are described in the publication of the Chinese utility model patent with publication number "CN 213130331U", wherein the publication describes: the cotton core in the absorption core body is rectangular, and the front end of the dust-free paper positioned on the upper layer of the cotton core is provided with a dumbbell-shaped first leakage-proof absorption block, so that the problem of leakage before menstrual blood can be effectively prevented by a dumbbell-shaped structure at the front end. However, when a woman sleeps at night by using the product, menstrual blood mainly flows to the rear crotch part, the rectangular cotton core is difficult to quickly permeate and absorb the menstrual blood, and the situation that the menstrual blood quickly flows to the edge of the absorption core body and is not absorbed in time to cause back leakage easily occurs.
Finally, as seen in the prior art described above, menstrual pants are a panty-type sanitary napkin that is worn with the waist portion of the menstrual pants fitted to the body based on waist-elastic members. For the waistline elastic component, a plurality of slender elastic rubber bands are adopted in the traditional scheme, but because the stress of the slender elastic rubber bands is concentrated, rib marks are easily generated on the abdomen, and the discomfort is increased. And in the scheme, the flat rubber band is adopted, so that the stress is more dispersed compared with the stress of a slender elastic rubber band, the rib mark generation condition is less, and the comfort is relatively better.
The invention further optimizes the technical scheme and solves the problems of stress concentration and poor comfort of the rubber band.

As shown in fig. 1 to 3, the present embodiment relates to a non-woven fabric menstrual period pants for preventing back leakage, which comprises a pants body 1 and an absorbent main body 2 disposed in the middle inside the pants body 1. Leg openings 11 are arranged on two sides of the lower end of the trousers body 1, the upper end of the trousers body 1 is constructed into an elastic side wall for fitting the waist and abdomen, and a waist opening is formed between the elastic side walls. The anti-back leakage menstrual period trousers are underwear-type sanitary towels and are used by women in a physiological period, when the anti-back leakage menstrual period trousers are used, legs are stretched into leg openings 11, the menstrual period trousers are lifted upwards to enable waist openings to be sleeved on waist and abdomen portions, and the upper ends of the menstrual period trousers are attached to the body through elastic side walls, so that wearing is completed.
In the solution shown in fig. 1, embossed guides 30 are arranged on the absorbent body 2 symmetrically back and forth along its centre. The distance between the rear side edge of the absorption main body 2 and the rear side edge of the trouser body 1 is smaller than the distance between the front side edge of the absorption main body 2 and the front side edge of the trouser body 1. The center line of the embossed guide 30 in the front-back direction is located on the rear crotch portion and coincides with the center line of the pants body 1 in the front-back direction. The main absorbent body 2 in this scheme is mainly used for absorbing menses, and the embossed guide 30 arranged on the main absorbent body 2 is formed by compressing the main absorbent body 2 along the thickness direction, and plays a role of buffering the menses or urine, and prevents the menses or urine from rapidly flowing to the periphery of the core. On the basis, the scheme considers the night use condition of the menstrual trousers, the absorption main body 2 is arranged towards the back side of the trousers body 1, namely the distance between the back side edge of the absorption main body 2 and the back side edge of the trousers body 1 is smaller than the distance between the front side edge of the absorption main body 2 and the front side edge of the trousers body 1, so that the size of the absorption main body 2 at the back side is larger, and the absorbed menstrual blood amount is relatively larger.
Further, the center line of the front-back direction of the embossed guide 30 in this embodiment is located on the rear crotch portion and coincides with the center line of the front-back direction of the pants body 1. Thus, the embossed guide 30 in the rear crotch portion is significantly larger than the embossed guide 30 in the front crotch portion with respect to the boundary between the front and rear crotch portions [ the position of the shortest distance between the leg openings 11 in the figures ]. Therefore, when the novel multifunctional embossing flow guide part is used at night, the embossing flow guide part 30 with more rear crotch parts plays good roles of drainage absorption and flow blocking and buffering.
Based on the structure, the menstrual period trousers capable of preventing menstrual blood from leaking out of the rear end of the menstrual period trousers can be effectively avoided.
In a further scheme, the absorbent main body 2 comprises a core 21, a water permeable surface layer 22 attached to the surface of the core 21, a leakage-proof PE film layer 23 attached to the lower side of the core 21, a non-woven fabric layer 24 extending to two sides of the core 21 to form leakage-proof side wings, a toilet paper layer 25 covering the core 21, and a plurality of lifting rubber bands 26 under the leakage-proof PE film layer 23. The lifting rubber band 26 is arranged along the length direction of the absorbent main body 2, and the lifting rubber band 26 can enable the absorbent main body 2 to be attached to the crotch of a human body. The edges of the water permeable surface layer 22 and the leak-proof PE film layer 23 exceed the core body 21 to form a joint part of the connecting pants body 1. In this scheme, the permeable surface layer 22 has the functions of skin friendliness and water permeability, the core body 21 is mainly used for absorbing menstrual blood or urine, the leakage-proof PE film layer 23 blocks the penetration of the body fluid, and the leakage-proof side wings constructed by the non-woven fabric layer 24 are mainly used for preventing side leakage. The permeable surface layer 22 and the leak-proof PE film layer 23 are compounded on the upper side and the lower side of the core body 21, the edges of the permeable surface layer and the leak-proof PE film layer exceed the core body 21 and are used for being hot-pressed with the connecting trousers body 1, and the connecting part is a joint part.
