Farrell teaches [an] effervescent cleansing composition
contained in a pouch formed from first and second substrate sheets,
at least one being water permeable. See col. 1, line 34 - col. 2, line
64. …
Farrell suggests a pouch having an abrasive non-woven
flexible sheet and a smooth sheet for rubbing against calluses.
While Example 5 illustrates a pouch formed of non-woven
polypropylene, the reference fails to specifically mention meltblown
or spunbond web, or spun lace web.
Brennan teaches that disposable baby wipes made with
spunlaced sheet have been commercially successful due to its
inherent softness. See col. 1, line 66 - col. 2, line 12. The reference
further teaches that spunbond webs and meltblown fibers in
comparison are relatively stiff. See col. 7, lines 20 - 25.
Farrell and Brennan fail to teach [a] high loft sheet.
Thaman teaches that a high loft sheet carded nonwoven fabric
resin-bonded to an air-lad nonwoven material is a most preferred
material for a dual-textured medicated pad for skin. See col. 4, lines
10 - 29. … The materials are said to have high degree of loft, greater
cleansing capability and oil removal and improved rigidity. See col.
1, line 63- col. 2, line 9. …
The examiner concludes (Answer, page 5)
Given the general suggestion in Farrell that the cleansing pouch
may comprise both smooth and abrasive non-woven sheets for effective
rubbing and cleansing, it would have been obvious to one having ordinary
skill in the art at the time the invention was made to have looked to the
prior arts such as Brennan for soft and abrasive nonwoven sheets used in
personal care art. … It would have been also obvious to the skilled artisan
to have modified the article of the combined references by substituting the
nonwoven material with the high loft carded nonwoven material as
motivated by Thaman because of an expectation of successfully
producing a dual-textured cleansing article with good cleansing capability
and rigidity.
