Abstract
Abstract A seam construction for an absorbent article comprises a layered composite portion of the absorbent article including a liquid pervious liner, a liquid impervious outer cover, and an absorbent medium therebetween. A pair of stretchable members are joined to the layered composite portion between respective side portions of the outer cover and the liner. The stretchable side members also extend outwardly beyond the opposite side portions of the outer cover and liner. The layered composite portion and each stretchable member form a seam construction that is resistant to liquid leakage and that provides a gentle transition between the layered composite portion and the stretchable members.
