  • Stretchable absorbent core
    Patent number: 8449516
    Abstract: A stretchable absorbent core (10) includes a stretchable base sheet (20), and a plurality of separate and independent absorbers (30) disposed at least on one side of the base sheet (20). The absorbers (30) are fixed to the base sheet (20) through respective fixing points (33) in such a design that the shape of each absorber is not deformed upon stretch of the base sheet (20). The stretchable absorbent core (10) exhibits stretchability between the fixing points (33). It is preferable that the stretchable absorbent core (10) does not exhibit stretchability at the fixing points (33).
    Type: Grant

  • Absorbent article
    Patent number: 8343125
    Abstract: An absorbent article (100) includes a topsheet (101), a backsheet (102), and an absorbent core (10). The absorbent core (10) includes a number of discretely and independently arranged absorbent members (30) located across a planar direction of the article (100). An intermediate sheet (20) is disposed between the topsheet (101) and the absorbent core (10) or between the backsheet (102) and the absorbent core (10). The absorbent members (30) are fixed to the intermediate sheet (20). It is preferable that an absorption rate of physiological saline solution measured by D/W method of each of the topsheet (101), the intermediate sheet (20), and the absorbent core (10) satisfies the following relationship: the topsheet (101)<the intermediate sheet (20)<the absorbent core (10).
