Claims17
An article for maintaining menstrual fluid within a vagina having labia minora, the article comprising:
- a flexible, elastic polymer film substrate having a body facing surface, an opposed garment facing surface, and a perimeter;
- adhesive applied in a closed pattern to the entire perimeter of the body facing surface of the substrate and arranged and configured to extend over about 5% to about 80% of the body facing surface of the substrate to sealingly attach to the labia minora of the body to maintain menstrual fluid within the vagina;
- and
- wherein (1) the substrate has a length as measured along a longitudinally extending centerline of about 20 mm to about 150 mm, a width as measured along a transversely extending centerline of about 20 mm to about 100 mm, (2) the article has a total fluid capacity of less than 3.0 g, (3) a shear force required to remove the adhesive from skin is greater than a force required to deform the substrate, and (4) the article is free to move with the body during use and recover its original shape while maintaining an adhesive seal to the labia minora of the body.

- a flexible, elastic polymer film substrate having a body facing surface, an opposed garment facing surface, and a perimeter;
- an adhesive selected from the group consisting of non-pressure sensitive adhesive substance, muco- or bioadhesive or mixtures thereof wherein the adhesive is applied in a closed pattern to the entire perimeter of the body facing surface of the substrate and arranged and configured to extend over about 5% to about 80% of the body facing surface of the substrate to sealingly attach to the labia minora of the body to maintain menstrual fluid within the vagina;
- and
- wherein (1) the article has a length as measured along a longitudinally extending centerline of about 20 mm to about 150 mm, a width as measured along a transversely extending centerline of about 20 mm to about 100 mm, and is sized, structured and arranged to fit in the region on the internal side of the labia but external the vagina, (2) the article has a total fluid capacity of less than 3.0 g, (3) a shear force required to remove the adhesive from skin is greater than a force required to deform the substrate, and (4) the article is free to move with the body during use and recover its original shape while maintaining an adhesive seal to the labia minora of the body.
