  • Publication number: 20210059869
    Abstract: An absorbent article (1) of the present invention includes a leg cuff (24). The leg cuff (24) has leg elastic members (25). The leg cuff (24) can be divided, by an imaginary line (IL) passing through the center (ct) between an outermost leg elastic member (25s) that is located farthest outward and an innermost leg elastic member (25i) that is located farthest inward, into a leg cuff first region (ST) that extends from the imaginary line (IL) up to and including the outermost leg elastic member (25s) and a leg cuff second region (IT) that extends from the imaginary line (IL) up to and including the innermost leg elastic member (25i). When the elongation amount of the leg cuff first region (ST) and the leg cuff second region (IT) in a natural state is defined as 0, and the elongation amount thereof in a maximally stretched state is defined as 100, the stress in the leg cuff first region (ST) is greater than the stress in the leg cuff second region (IT) when the elongation amount is 5.

  • Publication number: 20200289340
    Abstract: A leak-proof cuff (28) is divided into a lower region (40) and a upper region (41). The upper region (41) includes a first region (41A) located at the side of a free edge (28B) relative to the center in the width direction (Y) and a second region (41B) located at the side of a folding line (42). In each of the first region (41A) and the second region (41B), at least one elastic member (29) extending along the longitudinal direction (X) is provided in a stretched state. In a case where the elongation of the upper region (41) in a natural state is 0, and the elongation in a maximum stretched state is 100, the stress ?1 of the first region (41A) is larger than the stress ?2 of the second region (41B) at an elongation of 5, and the stress ?2 of the second region (41B) is larger than the stress ?1 of the first region (41A) at an elongation of 100.
