Abstract
An absorbent article with an outer perimeter is disclosed having a cover, a baffle, an absorbent core and a barrier means for intercepting fluid migrating from the absorbent core toward the outer perimeter of the sanitary napkin. The absorbent core has a protuberance that extends above a plane that is parallel to the absorbent core periphery. The barrier can encircle the protuberance so that in use the barrier effectively forms a gasket between the wearer's body, such as the crotch and/or thighs and the absorbent article.
Claims23
An absorbent article having an outer perimeter, said article comprising;
- a) a bodyfacing liquid-permeable cover;
- b) a garment faring liquid-impermeable baffle;
- c) an absorbent core disposed between said cover and said baffle, said absorbent core having a periphery inward from said outer perimeter and an absorbent protuberance which extends above a plane parallel to said periphery;
- and
- d) barrier means encircling said protuberance for intercepting body fluid migrating toward said outer perimeter, said barrier means being positioned between said periphery and said outer perimeter and having a height of between about 2 millimeters to about 25 millimeters, said barrier means having horizontal channel proximate said absorbent core partially dividing said barrier means into a too section and a bottom section wherein said absorbent core partially resides between top and bottom sections, said barrier means being sufficiently compressible so that a force of about 0.1 psi to about 2 psi is needed to compress said barrier at least 50 percent and said absorbent article having a flexure -resistance of less than about 1 kilogram.
An absorbent article having an outer perimeter, said absorbent article comprising:
- a) a bodyfacing liquid-permeable cover;
- b) a garment facing liquid-impermeable baffle;
- c) an absorbent core disposed between said cover and said baffle and adapted to absorb at least 5 grams of fluid, said absorbent core having a outer periphery inward from said outer perimeter and a longitudinally oriented protuberance which extends above a plane parallel to said periphery;
- and
- d) barrier means encircling said protuberance for intercepting body fluid migrating toward said outer perimeter, said barrier means being positioned between said outer perimeter and said periphery and having a height of between about 2 millimeters to about 25 millimeters thereby forming a gasket between a wearer's thighs and a portion of said absorbent core when said absorbent article is in use, said barrier means having a horizontal channel proximate said absorbent core partially dividing said barrier means into a top section and a bottom section wherein said absorbent core partially resides between said top and bottom sections, said barrier means being sufficiently compressible so that a force of about 0.3 psi to about 1.7 psi is needed to compress said barrier at least 50 percent and said absorbent article having a flexure-resistance of less than about 1 kilogram.
A sanitary napkin having an outer perimeter, said sanitary napkin comprising:
- a) a bodyfacing liquid-permeable cover;
- b) a garment faring liquid-impermeable baffle;
- c) an absorbent core disposed between said cover and said baffle, said absorbent core having a periphery with a predetermined thickness positioned inward from said outer perimeter, said absorbent core having a medially positioned, longitudinally oriented protuberance which extends above a plane parallel to said periphery;
- and
- d) a polymeric foam barrier encircling and delimiting said absorbent core, said foam barrier is selected from polyurethane, polyethylene, polypropylene and combinations thereof having a density of about 0.02 grams/cm.sup.3 to about 0.1 grams/cm.sup.3, said foam barrier having a horizontal channel proximate said absorbent core partially dividing said foam barrier into a top section and a bottom section wherein said absorbent core partially resides between said top and bottom sections.
