  • Patent number: 11633312
    Abstract: An absorbent article having a pair of longitudinal edges, front and rear transverse edges, a front end region, a rear end region, and a central region disposed between the front and rear end regions. The absorbent article has a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, a pair of outwardly convex longitudinal central channels formed at least in the central region. The traversal distance of the pair of outwardly convex longitudinal central channels decreases towards both ends of the channels to define a central closed area. The absorbent article has a rear channel defining a rear closed area in the rear end region.

  • Patent number: 8715258
    Abstract: An absorbent article having a pair of longitudinal edges, front and rear transverse edges, a front end region, a rear end region, and a central region disposed between the front and rear end regions. The absorbent article has a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, and a pair of outwardly convex longitudinal central channels formed at least in the central region. The traversal distance of the pair of outwardly convex longitudinal central channels decreases towards both ends of the channels to define a central closed area. The absorbent article has a rear channel defining a rear closed area in the rear end region. The absorbent core is profiled within the central closed area so that the central region has a caliper that is greater than the caliper of the outside of the central closed area.

  • Patent number: 8211074
    Abstract: An absorbent article having a backsheet. The backsheet has a garment facing side and a first end edge in the first end region. The absorbent article has an adhesive attachment mechanism on the garment facing side of the backsheet for securing the absorbent article to an undergarment. The adhesive attachment mechanism includes a central adhesive section on or along the longitudinal centerline and a pair of side adhesive sections, each transversely outboard of the central adhesive section. Side adhesive sections have first ends in the first end region. First ends of side adhesive sections extend substantially to the first end edge of the backsheet. First end of the central adhesive section is at least about 5 mm from the first end edge of the backsheet such that an adhesive free area is formed between the first end of the central adhesive section and the first end edge of the backsheet.

  • Publication number: 20060116653
    Abstract: In one aspect of the invention, the invention is directed to an absorbent article having a pair of longitudinal edges, front and rear transverse edges, a front end region, a rear end region, and a central region disposed between the front and rear end regions. The absorbent article comprises: a liquid pervious topsheet; a liquid impervious backsheet; an absorbent core disposed between the topsheet and the backsheet; a pair of outwardly convex longitudinal central channels formed at least in the central region. The traversal distance of the pair of outwardly convex longitudinal central channels decreases towards the both ends of the channels to define a central closed area which has a maximum length of 80-220 mm and a maximum width of 25-70 mm. The absorbent article further comprises a rear channel defining a rear closed area in the rear end region.
