Publication number: 20020103470Abstract: Absorbent articles such as disposable diapers, incontinent briefs, diaper holders, training pants, and the like, that provide dynamic fit about the wearer by the use of extensible, outwardly extending side panels. The side panel includes at least one discontinuity for dividing the tensile force extending the side panel into a waist-directing force and a leg-directing force. The waist-directing force is transmitted by the side panel to the waist area of the article to maintain the waist area in a snug, but comfortable, fit against the waist of the wearer. The leg-directing force is transmitted by the side panel to the leg cuff area of the article to prevent leakage between the leg cuff and the wearer's leg.Type: ApplicationFiled: January 31, 2001Publication date: August 1, 2002Inventors: John C.

Publication number: 20020095132Abstract: 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.Type: ApplicationFiled: January 18, 2001Publication date: July 18, 2002Inventors: Gregory Ashton, Frederick Michael Langdon
