Abstract

According to the instant invention, there is provided an anatomically form-fitting, generally self-adjusting disposable absorbent garment, preferably a diaper. The garment comprises a breathable elastomeric outer cover, resiliently stretchable to surround and closely conform to the contours of a wearer. The outer cover comprises opposed front and rear waistbands, together defining a waist opening, a crotch section disposed between the waistbands, a pair of elasticized leg openings disposed along outer most lateral sides of the crotch section and opposed front and rear panels separated by the crotch section. An absorbent insert structure is defined by opposed front and back waist sections and a pair of side sections connecting the waist sections, including a liquid impermeable backsheet, a bodyside liner essentially coterminous with the backsheet and an absorbent body disposed therebetween. A pair of elasticized flaps, attached to or formed from the bodyside liner, are disposed inwardly of the respective side sections and extend in the crotch section between the front and back waist sections of the insert.
