Abstract
Disclosed is an absorbent article including: a liquid-permeable topsheet on a skin surface; and a backsheet on a garment surface. First flexible hinges and second flexible hinges are formed to extend longitudinally of the absorbent article. The first flexible hinges are disposed symmetrically about a longitudinal centerline of the absorbent article to define a central absorbent portion having an absorbent layer therebetween. The second flexible hinges are disposed symmetrically about the longitudinal centerline and spaced outwardly apart from the first flexible hinges to define support portions between adjacent first and second flexible hinges and side portions outside the second flexible hinges. The first flexible hinges facilitate bending of the support portions from the central absorbent portion, and the second flexible hinges facilitate bending of the side portions from the support portions.
