  • Patent number: 9301885
    Abstract: An absorbent article includes a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent body between the liquid-permeable top sheet and liquid-impermeable back sheet. The top sheet exhibits a color difference in a range of 37-80, based on the L*a*b* color system and measured from a skin contact surface of the top sheet in a liquid dropping test. Further, the top sheet has a color-reducing agent having an IOB of 0.00-0.35, a melting point of no higher than 45° C. and a water solubility of 0.00-0.05 g in 100 g of water at 25° C. The absorbent article is configured to allow a user to visually confirm reduction in residue of highly viscous menstrual blood on the top sheet after its absorption, thereby providing reassurance to the user.

  • Patent number: 9233185
    Abstract: The purpose of the present disclosure is to provide an absorbent article that can be made smaller because the crown section continues to fit the wearer's excretory opening, which has a complex shape, both when dry before absorbing menstrual blood and when wet after absorbing menstrual blood, and with which leakage does not occur easily. This absorbent article is as follows: The absorbent article (1), which comprises a liquid-permeable top sheet (4), a liquid-impermeable back sheet, and a specified absorbent (7) between the liquid permeable top sheet (4) and the liquid-impermeable back sheet, is characterized in that: the absorbent article (1) has a crown section (2), which protrudes in the thickness direction of the absorbent article (1) in the region that is in contact with the excretory opening and comprises a specified cushion section; and in the central section, the crown section (2) has a compression workload (WC) of 10-50 (N·m/m2) and a compression resilience (RC) of 35-100%.
