Abstract
Abstract A labial pad (30) having an anatomically conformable configuration with a generally ovate geometry defined by a principal longitudinal axis (L), a minor transverse axis (T) and a generally orthogonal lateral or height axis (H), is comprised of a laterally upwardly directed projection (52) lying generally along the longitudinal axis within the posterior region (54) of the pad and having a prominence (64) proximate the distal end (60) thereof tapering toward the proximal end (58) along the longitudinal axis and to the opposed sides (62) along the transverse axis, wherein the projection is configured for disposition within the vestibule (32) of a wearer over a region bounded generally by the posterior labial commissure (36) and the labia terminating at or about the latter and extending forwardly therefrom over the vulva, to occlude the vestibule against flow of menses or the like while protecting the urogenitals from chafing contact.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
180 words
An anatomically, generally self-conforming sanitary napkin configured for partial labial disposition within the vestibule of a wearer and for at least partially occluding said vestibule respecting fluid flow therefrom, said sanitary napkin comprising: (a) a liquid-impermeable baffle; (b) a fluid absorbent positioned on said baffle and having a posterior region and an anterior region, said posterior region including a raised profile for projection within said vestibule intermediate the labia majora inwardly bounding same from a position porteriorly remote from the clitoris and extending to the rearward most aspect of said vestibule, and said anterior region merging with said posterior region for a generally external disposition about the vulvar region over said labia majora and spaced from said clitoris; and (c) a liquid permeable cover positioned over said absorbent and attached to said baffle, said cover having a physiologically hydrous characteristic such that when it is at a minimum moisture level during use, it has a moisture content at least eight times higher than a cover material constructed of a nonwoven, spunbounded material which does not have said physiologically hydrous characteristic.
Claim 2
Dependent Claim
180 words
An anatomically, generally self-conforming sanitary napkin configured for partial labial disposition within the vestibule of a wearer and for at least partially occluding said vestibule respecting fluid flow therefrom, said sanitary napkin comprising: (a) a liquid-impermeable baffle; (b) a fluid absorbent positioned on said baffle and having a posterior region and an anterior region, said posterior region including a raised profile for projection within said vestibule intermediate the labia majora inwardly bounding same from a position porteriorly remote from the clitoris and extending to the rearward most aspect of said vestibule, and said anterior region merging with said posterior region for a generally external disposition about the vulvar region over said labia majora and spaced from said clitoris; and (c) a liquid permeable cover positioned over said absorbent and attached to said baffle, said cover having a physiologically hydrous characteristic such that when it is at a minimum moisture level during use, it has a moisture content at least eight times higher than a cover material constructed of a nonwoven, spunbounded material which does not have said physiologically hydrous characteristic.
Claim 3
Dependent Claim
12 words
The sanitary napkin of claim 1 wherein said cover comprises spunweaved polyester.
Claim 4
Dependent Claim
208 words
An anatomically, generally self-conforming sanitary napkin configured for partial labial disposition within the vestibule of a wearer and for at least partially occluding said vestibule respecting fluid flow therefrom, said sanitary napkin comprising: (a) a liquid-impermeable baffle; (b) a fluid absorbent positioned on said baffle, said absorbent containing a plurality of microfibrous batts and a posterior region and an anterior region, said posterior region including a raised profile for projection within said vestibule intermediate the labia majora inwardly bounding same from a position posteriorly remote from the clitoris and extending to the rearward most aspect of said vestibule, and said anterior region merging with said posterior region for a generally external disposition about the vulvar region over said labia majora and spaced from said clitoris; (c) a transfer layer positioned over said absorbent containing a blend of cellulosic and polymeric fibers having a nonwoven fabric integrity; and (d) a liquid permeable cover positioned over said transfer layer and attached to said baffle, said cover having a physiologically hydrous characteristic such that when it is at a minimum moisture level during use, it has a moisture content at least eight times higher than cover material constructed of a nonwoven, spunbounded material which does not have said phsiologically hydrous characteristics.
Claim 5
Dependent Claim
208 words
An anatomically, generally self-conforming sanitary napkin configured for partial labial disposition within the vestibule of a wearer and for at least partially occluding said vestibule respecting fluid flow therefrom, said sanitary napkin comprising: (a) a liquid-impermeable baffle; (b) a fluid absorbent positioned on said baffle, said absorbent containing a plurality of microfibrous batts and a posterior region and an anterior region, said posterior region including a raised profile for projection within said vestibule intermediate the labia majora inwardly bounding same from a position posteriorly remote from the clitoris and extending to the rearward most aspect of said vestibule, and said anterior region merging with said posterior region for a generally external disposition about the vulvar region over said labia majora and spaced from said clitoris; (c) a transfer layer positioned over said absorbent containing a blend of cellulosic and polymeric fibers having a nonwoven fabric integrity; and (d) a liquid permeable cover positioned over said transfer layer and attached to said baffle, said cover having a physiologically hydrous characteristic such that when it is at a minimum moisture level during use, it has a moisture content at least eight times higher than cover material constructed of a nonwoven, spunbounded material which does not have said phsiologically hydrous characteristics.
Claim 6
Dependent Claim
42 words
The sanitary napkin of claim 3 wherein said cover has the ability to rewick fluid from said absorbent after said minimum moisture level is reached thereby assuring that a suitable moist interface is maintained between itself and the tissues of the vestibule.
