  • Patent number: 6840925
    Abstract: A throwaway wearing article for disposal of bodily discharges improved so that a cylindrical guide for bodily discharge can be brought in close contact with a zone surrounding the anus without use of an adhesive. A flat bag-like receptacle is formed on its upper sheet with an inlet means having the cylindrical guide adapted to guide bodily discharge such as loose passage into a receptacle. An elastically stretchable supporting member extending under extension between front and rear sections of the receptacle is operatively associated with a peripheral edge of the upper end of the cylindrical guide.

  • Patent number: 6762340
    Abstract: Disclosed is an absorbent article including: a liquid permeable surface structural body; a backing sheet; an absorbent core disposed between the surface structural body and the backing sheet. The surface structural body is formed by stacking bundles of continuous filaments into at least two layers and partially fixing the continuous filaments of the respective layers together. The individual continuous filaments extend over the entire length of the respective layers. The layers include: a lower layer positioned adjacent to the absorbent layer; and an upper layer positioned away from the absorbent layer and having a smaller width than that of the lower layer. The upper layer is located exclusively at a center portion or laterally opposite side portions of the lower layer.

  • Publication number: 20040002689
    Abstract: A pull-on disposable wearing article includes pants having a waist-hole and a pair of leg-holes, on one hand, and a liquid-absorbent pad placed on the inner side of the pants. On the other hand, the pants and the pad are coupled together by means of first and second coupler sheets extending between the pants and the pad. The pants and first and second coupler sheets are elastically stretchable in a longitudinal direction as well as in a transverse direction. A stretch stress of the pants is higher than those of the first and second coupler sheets and a stretch stress of the second coupler sheet is lower than that of the first coupler sheet.

  • Patent number: 6657102
    Abstract: Disclosed is an absorbent article including: a liquid permeable surface layer formed of continuous filaments individually extending over the entire length of the surface layer, the continuous filaments including at least heat-fusible continuous filaments; a backing sheet; and a fibrous absorbent core located between the surface layer and the backing sheet and containing heat-fusible fibers. Between the surface layer and the fibrous absorbent core, disposed is an absorbent sheet which is formed of superabsorbent polymer to have a plurality of through passages. The surface layer and the fibrous absorbent core are partially fusion-bonded to each other via the through passages formed in the absorbent sheet for retaining the absorbent sheet between the surface layer and the fibrous absorbent core.
