Abstract
An anatomically form-fitting, generally self-adjusting disposable absorbent garment comprising a breathable elastomeric nonwoven laminar outer cover having an absorbent insert structure attached and integrated thereinto while allowing substantially unrestricted functional stretchability of the outer cover. The insert is attached to the outer cover by selectively breakable sonic bonds along either of the waist and leg openings of the outer cover to accommodate various body shapes and sizes. Upon exertion of certain stresses against the garment by wearers having larger waist and/or leg sizes, the bonds break away and restore the inherent stretch properties of the corresponding region of the outer cover. The breakable bonds also maintain a neat, aesthetic appearance of the product and minimize interference of loose, unattached material during processing, storage and use of the article.
