  • Patent number: 7223261
    Abstract: The invention relates to an absorbent, disposable article, preferably a diaper, having a backsheet and a topsheet comprising a first waist region, a second waist region, and a crotch region interposed there between, a longitudinal axis, and an opening, which provides a passageway to a primary void space for receiving bodily exudates therein, positioned between the topsheet and the backsheet; whereby the opening is positioned in at least the crotch region along the longitudinal axis; whereby the topsheet is elasticated; and whereby the article has a shortened article portion, as defined herein, which has a shortened article length L, a stretched shortened article length Ls and a contacted shortened article length Lc, whereby the article and/or its topsheet has an specific elastic profile and/or a specific ratio of Lc to Ls.

  • Patent number: 7074215
    Abstract: A disposable garment having a localized retention zone for retention of the garment in its initial position on the body of a wearer. The retention zone has a higher coefficient of static friction than does the major area of the body-facing surface of the garment. The garment may also include localized areas having a lower coefficient of static friction than that of the major area to facilitate placement of the garment in a desired wearing position. Such lower coefficient of static friction areas can include the areas adjacent the leg openings and the area of the waistband that overlies the stomach of the wearer. Additionally, the garment can also include areas wherein the coefficient of static friction varies from high to low to provide improved retention and comfort over a wide range of wearing conditions and a wide range of movements of the wearer.

The article preferably has a slit opening with on each side elastic regions, preferably in the shape of an X, as shown in FIG.

  • Patent number: 6764478
    Abstract: Absorbent article having a containment assembly and highly extensible leg openings. The leg opening margins may have portions having differential properties, such as differential elastic extensibility. The absorbent article may also have highly extensible outer leg cuffs. Additionally, the absorbent article may have a narrow crotch region. The absorbent article may thus provide ease of application and removal, sustained dynamic fit, prevention of leakage, sustained wearer comfort, and desirable appearance.

  • Patent number: 6641568
    Abstract: Absorbent articles having improved sustained fit on the body, improved appearance through the period of use, and improved comfort for the wearer. The absorbent article has a containment assembly, a waist feature and a diagonal support member feature disposed so as to lie in the diagonal support zone of the wearer's body when the article is worn. The diagonal support member is designed to support the article from the small of the back, over the hip, and to the lower abdomen. The diagonal support member is distinct from the waist feature, which is designed to provide only enough circumferential tension to hold itself in position on the body. The absorbent article has a garment-like high-waisted appearance, gentle tension around the waist to avoid discomfort and/or pressure marking, good leakage protection, good sustained fit, and easy application and removal.

  • Patent number: 6626879
    Abstract: A disposable absorbent garment having an elastic waist panel that includes one or more localized retention zones for retention the garment in its initial, as-applied position on the body of a wearer. The retention zones includes materials that have a higher coefficient of static friction than does the major surface area that constitutes the inner, body-facing surface of the garment. The garment can also include localized areas having a lower coefficient of static friction than that of the major inner surface area of the garment to facilitate placement of the garment in a desired wearing position. Such lower coefficient of static friction areas can include the areas adjacent the leg openings and the area of the waistband that overlies the stomach of the wearer.
