  • Patent number: 10716718
    Abstract: An absorbent article that has a reduced tendency to shift when worn. The absorbent article includes a chassis with a front waist portion, a crotch portion, and a back waist portion. Side panels or ears are attached to the front and back waist portions of the chassis, and fastening components are attached to the back ears. Anti-skid elements are added to the outside surface and/or inside surface of the front side panels or ears and/or to the inside surface of the fastening tabs, such as by applying an elastomeric strip in a substantially vertical direction. When the absorbent article is fastened to the wearer attaching the fastening components on the back ears to the front waist portion of the absorbent article, the anti-skid elements interface with the front waist portion, the front ears, and/or the wearer to exert friction and thereby reduce shifting of the fastened absorbent article.

  • Patent number: 7922851
    Abstract: A closure tab is provided and includes a first substrate. A second substrate is adhesively attached to the first substrate. The second substrate has mechanical closure material formed thereon. A compression bond pattern is applied to the first substrate and the second substrate. The compression bond pattern includes at least one outwardly extending protrusion. The compression bond pattern may include, for example, circular bond points, stripes, or a decorative element. A method is also provided wherein the second substrate is compressed onto the first substrate by a patterned roller. The second substrate may be compressed onto the first substrate by a plurality of pins spaced in alternating offset rows.

  • Publication number: 20040064113
    Abstract: This invention relates to the field of absorbent articles in general, and more particularly to absorbent articles that have wetness/dryness indicators disposed thereon. Preferably, the disposable absorbent article, for example, a training pant, includes a disappearing wetness/dryness indicator that disappears when the article is wetted, and an appearing wetness/dryness indicator that appears when the article is wetted. The wetness/dryness indicators preferably allow a caregiver to interact with a child to promote toilet training. The wetness/dryness indicators are graphic elements that may or may not be related to one another, and that may or may not be related to other graphic elements on the article.
