<p>A disposable absorbent garment includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet. The topsheet, the backsheet, and the absorbent core form a layered assembly including a front region, a back region, and a crotch region disposed between the front region and the back region. The garment is characterized by a vertical longitudinal plane that extends substantially centrally through the front, back and crotch regions. Each of the front and back regions includes a pair of ear portions extending in substantially opposite lateral directions with respect to the longitudinal plane. Each ear portion is a breathable stretchable layer assembly having a plurality of vent sites. Further, each ear portion includes an outer layer that is an extension of the backsheet and which extends laterally to the side edge of the ear portion, and an inner layer that is an extension of the topsheet and which also extends laterally to the side edge of the ear portion. The ear portion also includes a stretchable material layer secured between the inner layer and the outer layer. The topsheet includes a central section that is generally disposed in a center section of the garment and over the core. Each of a pair of side sections of the topsheet extends laterally and forms the inner layer of two of the ear portions. The side section also forms an outer wall section of a leg cuff that extends longitudinally along the lateral side of the core. An inner wall section of the leg cuff is a portion of a substantially impervious material that extends below the leg cuff to sealingly engage the side edge of a polymeric film barrier disposed underneath the core. The substantially impervious material and the polymeric film barrier combine to form a substantially impervious containment structure about the sides and bottom of the core.</p> |
