  • 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: 8161594
    Abstract: A plural sided duster removably attachable to a handle. The duster may have two construction portions, each with an inwardly facing surface joined to the other to form a laminate construction. The construction portions may be longitudinally offset. The arrangement allows an attachment mechanism associated with the inwardly facing surface to be visible to the user, so the handle may be easily and removably attached to the duster at the attachment mechanism.
