  • Sanitary napkin with soft, pliable sides and relatively stiff ends
    Patent number: 5843267
    Abstract: A disposable absorbent article or pad provides improved wearer comfort because it is shaped to provide an optimal fit to the user's undergarment, it has soft, flexible sides to prevent chafing of the user's thighs, and it has relatively stiff ends to prevent the ends from curling up during use. The difference in flexibility between the pad's ends and sides is achieved by placing a core of absorbent material end to end along the longitudinal axis of the product and centered in the midsection of the product so that the absorbent material is present in the peripheral sections of the product's ends but is absent in the peripheral sections of the product's sides.
