  • Patent number: 10765570
    Abstract: An absorbent article comprises a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent core positioned at least partially intermediate the topsheet and the backsheet, and a distribution material comprising a wet-laid, three-dimensional fibrous substrate comprising at least 80% pulp fibers by weight of the wet-laid, three-dimensional fibrous substrate. The wet-laid, three-dimensional fibrous substrate comprises a continuous network region and a plurality of discrete zones that are dispersed throughout the continuous network region. The continuous network region comprises a first average density and the plurality of discrete zones comprise a second average density. The discrete zones are dispersed throughout the continuous network region. The first average density and the second average density are different.

  • Patent number: 10342717
    Abstract: An absorbent article comprises a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent core between the topsheet and the backsheet. The absorbent core comprises an absorbent material. The absorbent article further comprises a distribution material between the topsheet and the absorbent core. The distribution material is notionally divided in a front region, a back region and a middle region located between the front and the back region. Each of the front, back and middle regions is ? of the length of the distribution material. At least one of the front, back and middle regions of the distribution material comprises one or more layers. The one or more layers of the distribution material comprise a fibrous structure made of wet-laid fibers.

  • Patent number: 8383878
    Abstract: An absorbent article such as a diaper, training pant, and the like comprises a containment member that has a central zone and a barrier zone. The central zone has greater air flow according to the Air Permeability Test than the barrier zone. The barrier zone a greater hydrohead according to the Hydrostatic Head Pressure Test than the central zone. The containment member may be used for absorbent core formation and may have portions configured to serve as barrier leg cuffs for the finished absorbent article.

  • 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.

  • Patent number: 7320684
    Abstract: A disposable absorbent article having laterally opposing interiorly attached barrier cuff strips and at least one deployable belt strip. Each barrier cuff strip is attached to an interior surface of an absorbent assembly and has a longitudinally extending elastic gathering member attached adjacent to its proximal edge. The belt strip has a fixed end portion and opposing first and second edges connecting the fixed end portion and an opposing free end portion. The belt strip is attached in the fixed end portion and is deployed by being folded laterally outward such that the first edge extends laterally outward from one end point of a diagonal fold line and the second edge extends laterally outward from the opposing end point of the diagonal fold line. The belt strip may be tied to another belt strip or may be fastened to the waist region of the article or to another belt strip.
