Absorbent article with urine-permeable coversheet
An absorbent article having a backsheet, an absorbent core, a topsheet, and a genital coversheet. The topsheet has an opening positioned to allow exuded fecal material to pass therethrough when the article is worn by a wearer. The genital coversheet is positioned across a portion of the aperture and covers the wearer's genitals. A void space is formed between the genital coversheet and the absorbent core and a void space is formed between the topsheet and the absorbent core.
1. An absorbent article comprising:
a backsheet;
a topsheet made of material that is urine impermeable and feces impermeable, the topsheet having an elongate opening therethrough, the elongate opening having a front region and a back region, the elongate opening being continuous and positioned such that when the article is worn by a wearer, the front region is adjacent the wearer's genitals, and the back region will allow exuded fecal material to pass therethrough;
an absorbent core situated above the backsheet; and
a urine permeable genital coversheet partially attached to the article forming attached areas and unattached areas, and lying across the elongate opening in the front region in a position to cover the wearer's genitals, but not obstruct the back region, when the article is worn, the genital coversheet having a rearward transverse edge that is unattached to the article and traverses the elongate opening, said rearward transverse edge being spaced above said absorbent core beneath the elongate opening, wherein the genital coversheet is formed of a section of material distinct from a section of material forming the topsheet.
2. The absorbent article as in claim 1 , wherein the urine permeable genital coversheet is positioned above the topsheet and so as to be in direct contact with the wearer's skin when the article is worn.
3. The absorbent article as in claim 1 , wherein the urine permeable genital coversheet is positioned between the topsheet and the absorbent core, and wherein said coversheet is directly secured to the topsheet.
4. The absorbent article as in claim 1 , wherein said topsheet has two opposing inner side edges defining sides of the elongate opening, and portions of the urine permeable genital coversheet are directly secured to the topsheet along said opposing inner side edges and the urine permeable genital coversheet forms a pocket between said opposing inner side edges.
5. The absorbent article of claim 4 , wherein the topsheet comprises elasticated areas and non-elasticated areas, and the urine permeable genital coversheet is attached to the topsheet in the non-elasticated areas in a front region of the topsheet.
6. The absorbent article of claim 5 , wherein the urine permeable genital coversheet is attached in at least two attachment areas, at least one of the attachment areas being disposed along one inner side edge and another of the attachment areas being disposed along the other inner side edge, the average width of the urine permeable genital coversheet between said two attachment areas being larger than the average distance between said two attachment areas.
7. The absorbent article of claim 1 , wherein the topsheet has two opposing inner side edges and forward and rearward edges defining the elongate opening, and at least portions of the two opposing inner side edges have first and second elasticated areas therealong.
8. The absorbent article of claim 7 , wherein the respective first and second elasticated areas extend forward on the topsheet beyond the forward edge.
9. The absorbent article of claim 7 , wherein the respective first and second elasticated areas extend rearward on the topsheet beyond the rearward edge.
10. The absorbent article of claim 7 , wherein the respective first and second elasticated areas extend forward on the topsheet beyond the forward edge, and rearward on the topsheet beyond the rearward edge.
11. The absorbent article of claim 1 , wherein the urine permeable genital coversheet is extendable and is configured to form a pocket for the genitals when worn.
12. The absorbent article as in claim 1 , wherein the urine permeable genital coversheet comprises a spunbond nonwoven web, carded nonwoven web, or a formed film.
13. The absorbent article as in claim 1 , wherein a maximum length of the portion of the urine permeable genital coversheet that is present across the aperture is from 10% to 50% of a maximum length of the aperture.
14. The absorbent article as in claim 1 , wherein the absorbent article is sag-tolerant, and the topsheet has one or more longitudinal folds.
15. The absorbent article as in claim 1 , wherein the absorbent article is an adult diaper or infant diaper or training pants.
16. The absorbent article as in claim 1 , wherein the urine permeable genital coversheet comprises a carded nonwoven with an average caliper measured under compression of 0.3 psi of at least 0.3 mm and with a mean pore size of from 100 microns to 300 microns.
17. An absorbent article comprising:
a backsheet;
a topsheet terminating at a front waist band at a front end and terminating at a back waist band at a back end, the topsheet being made of material that is urine impermeable and feces impermeable, the topsheet having an elongate opening therethrough, the elongate opening having a front region and a back region, the elongate opening being continuous and defined by opposing longitudinal side edges and forward and rearward edges, and being positioned such that when the article is worn by a wearer, the front region is adjacent the wearer's genitals, and the back region will allow exuded fecal material to pass therethrough;
a urine permeable genital coversheet partially attached to the article forming attached areas and unattached areas, and lying across the elongate opening in the front region in a position to cover the wearer's genitals, but not obstruct the back region, when the article is worn, the genital coversheet having a rearward transverse edge that is unattached to the article and traverses the elongate opening, said rearward transverse edge being spaced above said absorbent core beneath the elongate opening, wherein the genital coversheet is formed of a section of material distinct from a section of material forming the topsheet;
a primary pair of respective primary first and second elongate elastic bands or elastic strands disposed on the topsheet along the respective opposing longitudinal side edges, each of the first and second elongate elastic bands or elastic strands respectively extending rearward beyond the rearward edge toward the rear waist band and forward beyond the forward edge toward the front waist band, and not meeting each other;
a secondary pair of respective secondary first and second elongate elastic bands or elastic strands disposed on the article laterally outside of the primary pair; and
an absorbent core situated above the backsheet;
wherein no elastic band or elastic strand is disposed on the topsheet along the respective forward or rearward edge of the elongate opening, that meets with both of said primary first and second elongate elastic bands or elastic strands, and also traverses a longitudinal axis of the topsheet.
