Sanitary napkin

Abstract

A sanitary napkin has leakage preventing walls (30) on a skin-side surface (2a) of a main body (2). The leakage preventing wall (30) has a skin-contacting portion (36), of which an inner edge (36B) is fixed at an inner edge's front end (32a) and an outer edge (36A) is fixed at an outer edge's front end (33a) located forward of the inner edge's front end (32a). Therefore, when the leakage preventing wall (30) is in a rising position, the skin-contacting portion (36) is inclined with the outer edge (36A) closer to the wearer's body than the inner edge (36B). Accordingly, the skin-contacting portion (36) can easily conform to the wearer's crotch on both sides of the vaginal opening.

[0001] This application claims priority from Japanese Patent Application No. 2003-177366 filed on June 20, 2003, the contents of which are incorporated herein by reference. technical field [0002] The present invention relates to a sanitary napkin comprising: a main body comprising a liquid absorbent layer; and a leak-proof wall extending longitudinally on a skin-side surface of the main body. Background technique [0003] In absorbent hygiene articles, the structure of the body typically includes a liquid-permeable topsheet, a liquid-impermeable backsheet, and a liquid-absorbent layer (absorbent core) disposed between the topsheet and the backsheet. Optionally, a leak-proof wall (cuff) is provided on the skin-side surface of the main body, thereby preventing side leakage of the liquid applied on the main body.

AI Technical Summary

Problems solved by technology

[0013] The sanitary napkin 100 is designed to absorb menstrual blood expelled from the vaginal opening 121 in the absorbent layer 103, but when the absorbent layer 103 tries to absorb too much menstrual blood, the menstrual blood may flow under the crotch and cause side leakage

If a space is formed between the skin-contacting portion 105a, 105a and the wearer's body as previously described, the menstrual blood flowing under the crotch tends to leak out of the skin-contacting portion 105a, 105a and reach the thighs 123, 123, making Underwear may be contaminated with menstrual blood

[0014] When the wearer sits down or sleeps, the menstrual blood that has flowed under the crotch tends to move forward or backward along the depressions 124, 124, which easily causes menstrual blood to leak out of the sanitary napkin 100
