  • Patent number: 4608047
    Abstract: This invention provides a sanitary napkin of the type emplacement in the inner crotch portion of an undergarment. The napkin comprises a central absorbent element having flaps extending from each of its longitudinal edges. The flaps extend to a sufficient length to allow the flaps to overlie the outer crotch portion of an undergarment with the flaps being sufficiently drapable so as to allow each to fold about the crotch portion at any of an infinite number of lines lying essentially parallel to the junction line between the absorbent element and each flap. Accordingly, when the sanitary napkin is applied to crotch portions of varying width, the napkin will conform to the dimensions of the crotch and be emplaced without wrinkling.

  • Patent number: 4551142
    Abstract: An absorbent material is provided for body fluid absorbent products which material has relatively high tensile strength, and is extremely flexible and may be incorporated into absorbent products without substantial loss in user's comfort. The material is made by forming a slurry of water wherein the solids comprise cellulosic fibers and hydrocolloidal material. The wet web is formed from the slurry and the web is then dried. The dry web is then compacted to a density of at least 110% and preferably at least 150% based on the density of the dry web. The resulting product has a tensile strength of at least 10 Kg/cm.sup.2 and the Gurley Stiffness of less than about 40 gm.
