Abstract

The present disclosure is directed to an absorbent article (e.g., a diaper or training pant) having a backsheet, an absorbent core and a topsheet provided with at least one opening adapted to receive fecal material. The article also includes a genital coversheet with one or more central longitudinal (partial) folds or fixed folds, which in use forms a pocket to cover the genitals, and which is positioned in, under or above part of the opening, such that a void space can be created between the genital coversheet and the absorbent core and such that a void space is present between the topsheet and the absorbent core. The present disclosure also relates to process for making pocket-shape genital coversheets for absorbent articles of the invention.

Claims

1. An absorbent article comprising:

a backsheet;

an absorbent core;

a topsheet provided with at least one opening adapted to receive fecal material, the topsheet and the opening thereof each having a front region and a back region, wherein a void space is present between the absorbent core and the topsheet; and

a genital coversheet positioned in, under or above the front region of the opening, the genital coversheet having one or more folds or partial folds to form a pocket that in use covers the genitals.

2. The absorbent article of claim 1, wherein the genital coversheet comprises one or more (partial) folds that extend in a substantially longitudinal direction.

3. The absorbent article of claim 2, wherein the folds or partial folds are fixed folds.

4. The absorbent article of claim 1, wherein the genital coversheet is urine permeable and the topsheet is urine-impermeable.

5. The absorbent article of claim 1, wherein the genital coversheet is positioned between the topsheet and the absorbent core, and wherein the cover sheet is attached to the topsheet, but not attached to the absorbent core.

6. The absorbent article of claim 1, wherein the genital coversheet comprises a single central longitudinal fixed fold or a single central longitudinal fixed partial fold.

7. The absorbent article of claim 1 wherein the genital coversheet is formed from a sheet with substantially parallel longitudinal side edges, which are attached to the topsheet with substantially longitudinally extending parallel opposing attachment areas.

8. The absorbent article of claim 1, wherein the opening has two longitudinal side edges and parts of the genital coversheet are attached to the topsheet along the longitudinal side edges of the opening and one or more parts of the genital coversheet are not attached to the absorbent article and form a pocket between the opening.

9. The absorbent article of claim 8, wherein the opening in the topsheet is a slit opening that has two longitudinal side edges and the topsheet comprises elasticated areas along at least part of the longitudinal side edges of the opening.

10. The absorbent article of claim 8, wherein the topsheet comprises elasticated areas and non-elasticated areas, wherein the genital coversheet is attached to the topsheet in the non-elasticated areas of the front region of the topsheet.

11. The absorbent article of claim 1, wherein the genital coversheet comprises a spunbond nonwoven web, carded nonwoven web, or a formed film.

12. The absorbent article of claim 1, wherein the maximum length of the part of the genital coversheet that is present above, in or under the opening is from 10% to 50% of the maximum length of the opening.

13. The absorbent article of claim 1, wherein the genital coversheet comprises a carded nonwoven with an average calliper (measured under compression of 0.3 psi) of at least 0.3 mm and with a mean pore size of from 100 to 300 microns.

14. The absorbent article of claim 1, wherein the absorbent article is an adult or infant diaper or training pants.

16. A process for making an absorbent article as in claim 1, wherein a genital coversheet material is provided with one or more folds or partial folds, which may optionally be attached to part of the non-folded genital coversheet material to form a fixed fold or folds, prior or subsequently to attaching the genital coversheet material to the topsheet.

17. The process of claim 16, wherein the attachment is done by attaching substantially longitudinally parallel extending side edges of the genital coversheet material to the topsheet with substantially longitudinally extending, parallel opposing attachment areas.

15. A process for providing an absorbent article comprising a backsheet, an absorbent core, and a topsheet with at least one opening adapted to receive fecal material, a void space between the absorbent core and the topsheet, and a genital coversheet in the form of a pocket, the genital coversheet being positioned in, under or above part of the opening, the process comprising the step of:

shaping a genital coversheet (material) into a pocket shape by vacuum forming, shaping it with a shaping tool, or by providing one or more folds or partial folds or fixed folds.
