  • Publication number: 20240115436
    Abstract: Disclosed is a feminine hygiene pad with an absorbent system including: an absorbent foam layer having a wearer-facing surface and an outward-facing surface, having a plurality of apertures providing z-direction passageways from the wearer-facing surface to the outward-facing surface; and a porous spacer layer beneath the foam layer and underlying a majority of openings of the apertures in an outward-facing surface of the foam layer. The spacer layer functions to provide structure, beneath the absorbent foam layer, that holds open a desired amount of unoccupied space between the absorbent layer and a backsheet of the pad, into which unabsorbed menstrual fluid may flow and temporarily reside, during the time required for the absorbent layer to effectively imbibe the fluid.

  • Patent number: 11813149
    Abstract: A feminine hygiene pad having a topsheet including a fibrous nonwoven web material having hydrophilic fibers, and an absorbent layer including an open-celled foam formed through polymerization of a high internal phase emulsion (HIPE) is disclosed. The topsheet and the absorbent layer are disposed in direct face-to-face relationship with each other, and attached to each other within a bonding region. Within the bonding region, each first identifiable point of attachment between the topsheet and the absorbent layer has a neighboring second identifiable point of attachment between the topsheet and the absorbent layer within a 6 mm radius of the first identifiable point of attachment.

  • Publication number: 20220401274
    Abstract: An absorbent article is provided. The absorbent article includes a liquid pervious film topsheet having a body facing surface and a garment facing surface; a backsheet having a body facing surface and a garment facing surface; an absorbent core having a body facing surface and a garment facing surface, the absorbent core being provided between the topsheet and the backsheet; and a bonding layer having a body facing surface and a garment facing surface. The body facing surface of the bonding layer has a fibrous matrix comprising cellulosic fibers and thermoplastic fibers, and the garment facing surface of the topsheet is directly bonded to the body facing surface of the bonding layer at discrete adhesive-free bond points.

  • Publication number: 20210038444
    Abstract: A method for isolating microorganisms from areas external and proximate a menstruating user's genital area is also disclosed. The method utilizes an absorbent article having a topsheet formed of nonwoven web material having favorable skin-feel qualities associated with nonwovens, and including hydrophilic fibers. A tendency of the topsheet material to absorb and retain discharged menstrual fluid, resulting from presence of hydrophilic fibers, is mitigated by inclusion of an absorbent core structure including suitable absorbent, open-celled foam material disposed directly beneath the topsheet in closely maintained, direct face-to-face contact with the outward-facing surface thereof. The absorbent foam may be suitably manufactured so as to have the ability to effectively draw fluid from the topsheet and retain it away from the topsheet. In such configuration, growth of microorganisms that might by supported by fluid retained by the topsheet, proximate the wearer's skin surfaces, is reduced or prevented.
