  • Patent number: 9522212
    Abstract: An individually packaged absorbent article has a pair of flaps for securing the absorbent article to clothing of a wearer. The absorbent article is folded multiple times along multiple folding axes such that the pair of flaps is folded over a liquid-permeable top sheet and the top sheet faces inward. The top sheet has a blood lubricating agent containing region, which contains a predetermined blood lubricating agent, in an area which overlaps with the pair of flaps in the thickness direction of the absorbent article. Moreover, the absorbent article is provided with a spacer for forming a space between the pair of flaps and the blood lubricating agent containing region of the top sheet.

  • Patent number: 9480610
    Abstract: In an absorbent part of an absorbent product, super absorbent materials located between two sheets in an absorbent area swell by absorption of moisture of excrement, and spaces extending in a longitudinal direction from an opening, which is formed at a portion of upper absorbent layer facing the crotch region of a wearer, are formed between a non-absorbent area where the super absorbent materials do not exist and the upper absorbent layer and between the non-absorbent area and a lower absorbent layer. In the absorbent product, through the spaces, moisture of excrement in the second excretion and later can be quickly diffused over a wide area along the longitudinal direction of the absorbent part, and the moisture of excrement can be absorbed in a wide area of the absorbent part. As a result, it is possible to maintain high absorbing ability in multiple excretions in the absorbent product.

  • Patent number: 9456933
    Abstract: A disposable wearing article includes an absorber having a crotch region. The central curving unit that allows the absorber to be convex in the inner direction is formed at a center in the widthwise direction of the crotch region. The first curving unit that allows the absorber to be convex in the outer direction is formed in the crotch region and outboard of the central curving unit. The second curving unit that allows the absorber to be convex in the inner direction is formed in the crotch region and outboard of the first curving unit. The concave unit is formed in the absorber to be concaved inwardly in the widthwise direction at the outside in the longitudinal direction relative to the first curving unit. The second curving unit is arranged outboard of an inside edge in the widthwise direction of the concave unit in the widthwise direction.
