  • Interlabial absorbent article with improved flushability characteristics
    Patent number: 7514591
    Abstract: An interlabial absorbent article configured for disposition primarily within the vestibule of a female wearer includes a generally liquid permeable cover sheet, a generally liquid impermeable back sheet, and an absorbent material disposed between the cover sheet and the back sheet. The back sheet has a water vapor transmission rate that is at least about 20% of a water vapor transmission rate of the cover sheet. The cover sheet and said back sheet may have a contact angle mismatch of less than about 25%. The absorbent material may have a density greater than water. Upon being flushed, the article has an initial neutral buoyancy and subsequently sinks within about 7 days from being flushed.

  • Absorbent article with time-delayed absorbent binder composition
    Patent number: 7138560
    Abstract: A personal care absorbent article includes a generally liquid permeable cover sheet, a generally liquid impermeable baffle, and an absorbent material disposed between the cover sheet and the baffle. A water soluble flexible absorbent binder composition is applied between the cover sheet and the baffle and functions as a primary absorbent material and to adhere the cover sheet to the baffle. The absorbent binder composition includes a crosslinked absorbent polymer and a polymer dispersion added in an amount so as to maintain structural integrity of the article for a time period of at least about two hours after the article is immersed in water by being flushed.

  • Delayed dispersion interlabial absorbent article
    Publication number: 20040122403
    Abstract: An interlabial absorbent article configured for disposition primarily within the vestibule of a female wearer includes a generally liquid permeable cover sheet, a generally liquid impermeable back sheet, and an absorbent material disposed between the cover sheet and the back sheet. A time-delayed water soluble adhesive combination joins the cover sheet and back sheet together with the absorbent material sandwiched therebetween. The adhesive combination is configured so as to maintain structural integrity of the article for a time period of at least about two hours after the article is immersed in water by being flushed while ensuring that the article breaks up within about 24-72 hours after flushing.
