Abstract

A compression groove base point (16) is formed where compression grooves (12) formed in left-right symmetry on both sides of a center line (CL) that runs in the longitudinal direction of a sanitary napkin (1), or where lines that extend from the center lines of the compression grooves (12) intersect at a position corresponding to the anterior (31) of the intergluteal cleft of a wearer, and a left-right pair of outer line inflection points (17) are formed on the outer line at the rear edge of the sanitary napkin, said outer line being formed in a wave shape having left-right symmetry. Easily-deformed sections (18) according to compression grooves (10) are provided on or near two imaginary lines (S), which join the compression groove base point (16) and the left and right outer line inflection points (17) and have a separation width that gradually widens towards the rear, and said easily-deformed sections (18) easily deform in the transverse direction of the sanitary napkin (1) in whichthe compressed grooves (10) serve as the proximal end.

Description

technical field [0001] The present invention relates to absorbent articles such as sanitary napkins, panty liners, incontinence pads, and disposable diapers for absorbing body fluids such as menstrual blood, secretions, and urine. The absorbent article deforms in association with the contour line of the rear end of the absorbent article to fit on the convex portion of the buttock cleft. Background technique [0002] Conventionally, as absorbent articles such as sanitary pads, sanitary napkins, and incontinence pads, liquid-impermeable back sheets such as polyethylene sheets or polyethylene sheets laminated with non-woven fabrics and non-woven fabrics or liquid-permeable back sheets are known. An absorbent article in which an absorbent body made of cotton-like pulp or the like is interposed between liquid-permeable top sheets such as plastic sheets. [0003] Many improvements have also been made to this absorbent article, and various means for closely fitting the body to pre...
