Abstract

The invention is generally accomplished by providing an incontinent garment or feminine pad having an indicator thereon to aid in proper placement of the pad onto the body of the wearer.

The invention in preferred form provides a sanitary napkin configured for partial labial disposition within the vestibule of the wearer, and for at least partially occluding said vestibule respecting fluid flow therefrom, said napkin comprises a fluid-absorbent body having a posterior region including a raised profile for projection within the vestibule intermediate the labia majora inwardly bounding the same from a position posteriorly remote from the clitoris and extending to the rearwardmost aspect of said vestibule, and anterior region merging with said posterior region and for generally external disposition about the vulvar region over said labia majora and spaced from said clitoris with a visual and/or tactile indicator located in the area of the pad that is to be placed immediately below the vestibule of the wearer.

Claims

1. A device for absorption of body exudate comprising an absorbent pad, a liquid permeable body side member, a liquid impermeable backing member and said absorbent therebetween wherein there is provided on the body side of said device a flow zone indicator means for connoting accurate placement of said pad onto the wearer'"'"'s body in the region where greatest exudate flow will contact the flow zone indicator such that the wearer of said pad is able to adjust placement of said pad to locate it in the area of greatest exudate flow.

2. The device of claim 1 wherein said pad, a feminine napkin, is configured for at least partial labial disposition.

3. The device of claim 1 wherein said indicator comprises ink printed on the underside of a bodyside cover material of the pad.

4. The device of claim 1 wherein said indicator is disposed in the region of the pad to be placed to occulude the vaginal opening.

5. The device of claim 1 wherein said indicator means comprises embossing as the indicator.

6. The device of claim 1 wherein said indicator is an area both embossed and colored.

7. The device of claim 1 wherein said indicator is colorant printed on the absorbent of the pad below a semitransparent cover.

8. The device of claim 1 wherein said indicator is an apertured area of the bodyside cover of said pad.

9. The device of claim 1 comprising an incontinence pad.

29. The device of claim 1 comprising a sanitary napkin.

10. 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 napkin comprising a fluid absorbent body having a posterior region included 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 rearwardmost aspect of said vestibule, and an 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 wherein said pad is provided on the body side with an indicator means for connoting when said napkin is in a position at least partially occluding said vestibule.

11. The sanitary napkin of claim 10, wherein said fluid absorbent body is comprised of a top, bodyside surface, a bottom, garment-contacting surface, and perimetral sides, said raised profile extending from said top surface within said posterior region.

12. The sanitary napkin of claim 10, wherein said raised profile is impressed within said fluid-absorbent body, having a generally shape-sustainable precursor configuration for projection within said vestibule.

13. The sanitary napkin of claim 12, wherein said fluid absorbent body includes a generally longitudinal pleat extending from the posterior end of said napkin and centrally-disposed relative to the opposed sides thereof for establishing a profile precursor having a generally transverse curvature respecting said longitudinal pleat.

14. The sanitary napkin of claim 13, wherein said pleat includes at least one bond juncture within the interior vertex region of said bottom surface for maintaining said profile precursor.

15. The napkin of claim 10 wherein said indicator means comprises a color indicator contrasting with the remainder of the bodyside surface of said napkin.

16. The napkin of claim 10 wherein said indicator means comprises an embossed area.

17. The napkin of claim 10 wherein said indicator means is located on said posterior region of said napkin including a raised profile.

18. The napkin of claim 10 wherein said indicator means is comprised of a dye on the interior of the bodyside covering of said napkin.

19. The napkin of claim 10 wherein said indicator means comprises perforations of the bodyside liner.

20. The napkin of claim 10 wherein said napkin is about 5 to 6 inches in length and said means to indicate accurate placement comprises a teardrop-shaped visual indicator between about 1/2 inch to 1 inch wide and between about 11/4 and about 21/4 inches long placed to begin between about 1/2 and about 3/4 inch from the posterior end of the said napkin.

21. The napkin of claim 10 wherein said indicator has a width comprising between about 8% and about 20% of the pad length and an indicator length of generally between about 20% and about 40% of the length.

22. A labial pad having an anatomically conformable configuration with a generally ovate geometry defined about a principal longitudinal axis, a minor transverse axis and a generally orthogonal lateral axis, said pad including a laterally upward directed projection lying generally along said longitudinal axis from a prominence proximate the distal end thereof and tapering both forwardly and to the opposed sides along said transverse axis;

wherein said projection is configured for disposition within the vestibule of a wearer over a region bounded generally by the posterior labial commissure and the labia majora terminating proximate the latter at a location spaced from the clitoris wherein the area of said projection is provided with an indicator means for connoting the accurate placement of said pad onto said region of the body of the wearer.

23. The labial pad of claim 22, comprising an absorbent body for retention of menses and a fluid transmissive cover overlying at least a portion of the top surface of said pad for passing menses to said absorbent body, wherein said overcover is comprised of a material characterized as physiologically hydrous within the environment of said vestibule.

24. A labial pad comprising a fluid-retentive body bearing a physiologically hydrous cover provided with positioning means for connoting accurate placement of said pad onto the body of the wearer.

25. A labial pad configured for partial interposition within the vestibule of a user to occlude menstrual fluid, comprising a contoured absorbent body defined spatially about a principal longitudinal axis, a minor transverse axis and generally orthogonal lateral axis, having a posterior region for anatomical cooperation within said vestibule and an anterior region for anatomical cooperation over the vulva and spaced from the clitoris of the user;

said absorbent body comprised of a plurality of microfibrous webs disposed laterally in face-to-face engagement, lying within said posterior region generally edgewise along said longitudinal axis and within said anterior region generally facewise across said transverse axis wherein said pad is provided with an indicator means for connoting occluding disposition of said pad at least partially within the vestibule of said user.

26. The labial pad of claim 25, including a set along said longitudinal axis for establishing a structural predisposition within said posterior region to form a generally transversely disposed inverted "V"-shaped projection for disposition within said vestibule.

27. The labial pad of claim 26, further comprising a physiologically hydrous cover.

28. The labial pad of claim 26, further comprising a transfer layer of a nonwoven fabric overlying said microfibrous webs.
