    Abstract: An absorbent article is curved in a saucer like shape in the transverse direction. The absorbent article offers not only a better fitting and feeling product to the wearer, but also has better flow characteristics. The article is formed by having an absorbent core that is made from multiple strips of absorbent material arranged in a stepwise manner so as to form a gradient. These strips may be of uniform or varying width and maybe made from a combination of one or more suitable material types.

    Abstract: An absorbent article having a substantially oblong shape, which is superior in liquid-proof performance and fitness, includes a liquid permeable top sheet, a back sheet, an absorbent body having elasticity disposed between the top sheet and the back sheet, and a compressed portion compressing the top sheet and the absorbent body. The compressed portion is disposed continuously to form a protrusion in a longitudinal direction to define a substantially U shape. The absorbent portion has a low elasticity portion, disposed on one part of the absorbent body, and formed so that elasticity weakens when compression to a prescribed thickness is carried out. The low elasticity portion is disposed in the vicinity of an end protruding the most in the longitudinal direction of the substantially U shape.

  • Publication number: 20070055210
    Abstract: A sanitary napkin has a top layer, an absorbent layer and a bottom layer with a sensor layer. The absorbent layer has a hollow portion covered with a silk-made cover layer and has multiple holes defined in the cover layer, wherein some silk cloth filled inside the hollow portion. By having the hollow portion with silk cloth, the menstrual blood is drained quickly and absorbed by the absorbent layer to keep the sanitary napkin dry at the top layer and to avoid toxic vapor. Moreover, the holes on the cover layer provide a ventilating efficiency and the silk is cool to be contact so that muggy feeling is efficiently reduced. The sensor at the bottom layer conveniently indicates the changing occasion to the user.

    Abstract: Absorbent articles for absorbing a bodily fluid comprise a pad region and a pre-formed conformable gluteal region. The pad region includes a first absorbent core, a liquid pervious surface, and a liquid impervious surface, wherein the absorbent core of the pad region is positioned between the liquid pervious surface and the liquid impervious surface. The conformable gluteal region includes a second absorbent core that is in fluid connection with the first absorbent core in the pad region. The gluteal region is configured to secure at least a portion of the absorbent article between a user's buttocks, and is further configured to wick fluid from the pad region. The absorbent article extends greater than about 12 inches in length.
