Appeal 2006-2263
Application 09/859,665
We AFFIRM-IN-PART and REMAND.
INTRODUCTION
Appellants claim a personal care absorbent article and a method for
treating a viscoelastic proteinaceous fluid (Claims 1 and 32). The
viscoelastic proteinaceous fluid may include menses (claim 15). The
method includes adding a “treatment chemistry” which may include a water
soluble gelling agent which cross-links protein to an absorbent article
(Specification 4-5). The water soluble gelling agent, for example, reacts
with the viscoelastic proteinaceous fluid to increase the viscosity (i.e.,
thicken) the fluid and prevent it from leaking out of the absorbent article
(Specification 31).
Claims 1 and 15 are illustrative:
1. A method for treating a viscoelastic proteinaceous fluid, whereby
management of said viscoelastic fluid by a personal care absorbent article is
improved, comprising the steps of:
treating at least one portion of said personal care absorbent article
with at least one treatment chemistry selected from the group consisting of
water-soluble gelling agents which crosslink protein, thickening agents,
plasma precipitators and combinations thereof; and
contacting said at least one portion of said personal care absorbent
article with said viscoelastic fluid, thereby one of altering at least one
property of said viscoelastic fluid and altering an interaction between said
absorbent article and said viscoelastic fluid;
wherein said personal care absorbent article includes a fluid pervious
polyolefin cover sheet, a fluid impervious backsheet, and an absorbent core
between them.
