  • Patent number: 5514104
    Abstract: The present invention provides improvements in absorbent products, but is particularly useful with urinary incontinence pads. An embossed pattern on the bottom layer of the double layer absorbent core construction improves the removal of urine or other fluids from the discharge zone to be ready for next void. One or more V-shaped notches cut at both ends of the pad provides the ergonomic fit of the pad to reduce the inevitable stiffness. The sides are designed as a flap which curves during the sealing process and provide natural curved flaps which form a soft gasket cushion and yields extra leak protection in the crotch area.
