Sanitary napkin capable of preventing back-blow

Abstract

The invention discloses a sanitary napkin that can avoid flowing backward. The sanitary napkin is provided with a body internally provided with a compound absorption layer; a laminating edge is formed around the body and a stopped-flow belt which can be stretched backwards is fixedly arranged in a proper place at the front end of a surface layer of the body; after the sanitary napkin contacts theskin, the stopped-flow belt is drawn upwards and goes deep into bottom sulcus; therefore, the sanitary napkin can not only prevent menstrual blood from blocking in the bottom sulcus, but also lead the menstrual blood to flow towards the sanitary napkin by the leading effect of the stopped-flow belt, thus avoiding flowing backwards of the menstrual blood and realizing extremely good absorption effect.

Description

technical field [0001] The invention relates to a sanitary napkin that can prevent backflow, especially a sanitary napkin design that can prevent menstrual blood from flowing backward through the groin. , can make the anti-flow belt go deep into the groin, and achieve excellent anti-back flow effect. Background technique [0002] In recent years, in order to make women have a more comfortable life during menstruation, the design of sanitary napkins has become more extensive, such as sanitary napkins with diversion grooves, which can block the inappropriate infiltration and outflow of menstrual blood, such as extended sanitary napkins, which can Ladies can also have a sound sleep at night, such as wing-shaped sanitary napkins, so that ladies do not have to be restricted in action, and aromatic sanitary napkins, which can reduce odor and increase comfort. [0003] Among them, in order to prevent women from turning their bodies unconsciously and causing menstrual blood to flow...

Problems solved by technology

[0003] Among them, in order to prevent women from turning their bodies unconsciously and causing menstrual blood to flow backward during sleep at night, the industry has designed a lengthened sanitary napkin for night use, so that the length can be extended to make menstrual blood flow backward. It can still be absorbed by sanitary napkins to prevent menstrual blood from staining the underwear; however, some practitioners have found that although the lengthened sanitary napkins can absorb the menstrual blood that flows backward through the increase in length, when the menstrual blood flows along When the groin flows backward, the menstrual blood is not absorbed by the sanitary napkin as soon as it flows out, but after flowing to the rear end, it will flow to one side due to the inclination angle of the body and then be absorbed by the sanitary napkin. There are concerns about side leakage, and the menstrual blood that is not absorbed by the sanitary napkin tends to accumulate in the groin

[0004] Therefore, some practitioners have designed a sanitary napkin with a protruding part formed in the center of the back end of the sanitary napkin. The protruding part can be used to extend into the groin, and when the menstrual blood flows backward with the groin, it can pass through the protruding part. Absorb menstrual blood directly to avoid side leakage and residual menstrual blood in the groin; but the protrusion formed in the center of the back end of the tampon is formed when the tampon is unfolded, so when the tampon is attached to the underwear and worn , it is not easy to locate the protruding part at the groin, and its effect cannot be exerted

[0005] The problem with the above structure is that the protruding part on the sanitary napkin is in a fixed shape with the sanitary napkin body, so when the sanitary napkin contacts the skin, it is not easy to adjust the protruding part to snap into the femoral groove. Protrusions can't really do their job
