    Abstract: A disposable absorbent article includes a sheet member, an absorbent core, at least one front leg elastic member, and at least one rear leg elastic member. The leg elastic members intersect at left and right intersections located in a crotch region of the sheet member. The left and right intersections are placed at any position on the outer side in the lateral direction relative to the vicinity of left and right side edges of the absorbent core in the crotch region. The front leg elastic member has left and right front leg contraction-reduced sections located on the outer side in the lateral direction relative to the left and right intersections. The left and right front leg contraction-reduced sections are cut so as to have reduced contractile forces. The rear leg elastic member has left and right front leg contraction-reduced sections located on the outer side in the lateral direction relative to the left and right intersections.

  • Patent number: 7910795
    Abstract: A technique for imparting latent elasticity to components of an absorbent article is provided. More specifically, a latent elastic film that contains a crosslinkable semi-crystalline polyolefin is initially incorporated into an absorbent article. The film is not highly elastic prior to crosslinking and is thus dimensionally stable. Consequently, the film need not be maintained in a mechanically stretched condition during attachment to other components of the absorbent article, which provides for greater freedom in the location and manner in which the components are attached together. Once incorporated into the absorbent article, the semi-crystalline polyolefin is crosslinked to form a three-dimensional network having elastic memory. The film may also be heat activated, either through crosslinking or an additional step, to cause the film to shrink and further improve its stretch characteristics.

Front joint zones extend from a front end to points lying aside from a front center line toward the middle zone and front segments of first and second barrier sheet-biasing elastic members have front maximally spaced points to define the maximum distance between the points. Rear joint zones extend from a rear end to a rear center line and rear segments of the respective elastic members have rear maximally spaced points between which the rear segments are maximally spaced from each other.

    Abstract: A disposable absorbent garment includes a body chassis having a terminal front waist edge, a terminal back waist edge longitudinally spaced from the terminal front waist edge, a first length defined between the terminal front waist edge and the terminal back waist edge, and a laterally extending centerline defined half way between the terminal front and back waist edges. An absorbent insert is fixedly secured to the body chassis. The absorbent insert has a retention region including an absorbent material. The retention region has first and second longitudinally spaced boundaries and a second length defined between the first and second boundaries. The second length is less than or equal to 50% of the first length, and at least 70% of the second length is positioned between the centerline and the terminal front waist edge. There is no absorbent material disposed outside of the retention region defined between the first and second boundaries.

  • Patent number: 7862549
    Abstract: Variable stretch composites having one or more first elastomeric members disposed on a first region of an extensible substrate, and one or more second elastomeric members disposed on a second region of the extensible substrate which different from the first elastomeric members to provide variable properties to said regions of the composite. The composite has been incrementally stretched to at least partially break up the structure of the substrate in order to reduce its resistance to stretch. The variable stretch composites are useful for disposable and durable articles, such as disposable absorbent articles including diapers, pull-on diapers, training pants, incontinence briefs, catamenial garments, baby bibs, and the like, and durable articles like garments including sportswear, outerwear and the like. The present invention also relates to methods of forming such variable stretch composites.

  • Patent number: 7857801
    Abstract: A disposable diaper including a chassis and an absorbent assembly. The chassis includes laterally opposing side flaps formed by laterally inwardly folded portions of the chassis and deployable chassis ears formed by other laterally inwardly folded portions of the chassis. Each chassis ear is held laterally inwardly folded until being released and unfolded laterally outward so as to project laterally outward beyond the adjacent side flap. An elastically extensible stretch waistband overlies portions of the laterally opposing chassis ears and extends laterally across the waist region between them.
