Abstract
An absorbent article is described which has a moisture-impervious backing layer, a liner sheet comprising an integral sheet, and an absorbent-core layer positioned between the liner sheet and the backing layer. Raised elasticized barrier means form a pocket to receive exudates. The barrier means may include elastic bands that are attached only to the liner sheet in the crotch portion of the article, such as by an adhesive. The liner sheet is bonded to the backing sheet adjacent leg-opening portions of the article, but is not bonded to the backing sheet at regions of the liner sheet adjacent first and second edges of the elastic bands, such as from at least about 5 mm to about 20 mm adjacent the first and second edges of the elastic bands. Preferably, the liner sheet is free of adhesive for a region of about 8 mm to about 12 mm adjacent the first and second edges of the elastic bands. The absorbent article may be substantially hourglass shaped, or substantially rectangular shaped. The elastic bands may be disposed on the inner sheet in a serpentine or linear array. A method for manufacturing the absorbent article also is described.
