Absorbent article having a pocket for receiving and storing faeces and method for its manufacture
An absorbent article, such as an incontinence shield, diaper, pant-diaper, belt diaper or the like, includes a topsheet, a backsheet and an absorbent core placed therebetween. The absorbent core has two longitudinal edges, and a front and a rear transverse edge, wherein the rear transverse edge possesses a recess with at least one pair of opposing edges. The recess forms a pocket for receiving and storing faeces, wherein the pocket's extension is defined by the edges of the recess. The article provides a simple, practical and cheap solution for handling of faeces without obviously compromising the liquid absorption properties.
1. An absorbent article comprising:
a topsheet, a backsheet and an absorbent core placed therebetween, a front and a rear transverse edge, two longitudinal edges, and a transverse center-line which divides the article into a front end portion adapted to lie adjacent to or in contact with a wearer's abdomen when in use, and a rear end portion adapted to lie adjacent to or in contact with the wearer's backside when in use, said absorbent core having two longitudinal edges, a front transverse edge, and a rear transverse edge,
wherein the rear transverse edge of the absorbent core possesses a recess with at least one pair of opposing edges, the recess forms a pocket for receiving and storing faeces deposited in the article's rear end portion, the pocket's extension is defined by the edges of the recess, and the topsheet of the absorbent article is fixed to the backsheet in the recess, and
an elastic element is arranged to extend substantially across the recess between its opposing edges in a direction parallel to the transverse centerline of the article, the elastic element directly attached to the opposing edges of the recess.
2. The absorbent article according to claim 1 , wherein the recess is V-shaped when the article is in an extended state.
3. The absorbent article according to claim 2 , wherein a base of the V-shaped recess lies in direct connection with the rear transverse edge of the absorbent core and a tip of the V-shaped recess points in a direction of the article's transverse center-line.
4. The absorbent article according to claim 3 , wherein an angle between the edges of the recess is ≧30° and a length of the edges of the recess is ≧5 cm.
5. The absorbent article according to claim 1 , wherein the elastic element comprises at least one elastic thread.
6. The absorbent article according to claim 1 , wherein the elastic element is connected to the rear transverse edge of the absorbent core.
7. The absorbent article according to claim 6 , wherein the elastic element is located within 0.1-10 mm from the rear transverse edge of the absorbent core.
8. The absorbent article according to claim 1 , wherein the absorbent article further comprises a waist elastic system connected to at least one of the article's transverse edges.
9. The absorbent article according to claim 8 , wherein the waist elastic system is located in the rear end portion of the article.
10. The absorbent article according to claim 1 , wherein the recess has a substantially convex shape when the article is in an extended state.
11. The absorbent article according to claim 1 , wherein the recess has a substantially rectangular shape when the article is in an extended state.
12. The absorbent article according to claim 1 , wherein the recess has a substantially circular shape when the article is in an extended state.
13. The absorbent article according to claim 1 , wherein the absorbent core has two or more layers, and the recess extends through at least one of said layers.
14. The absorbent article according to claim 13 , wherein the recess extends through at least one of said layers, and the recess has the same or different dimensions in each layer.
15. The absorbent article according to claim 1 , wherein the elastic element is disposed between the topsheet and the backsheet.
16. The absorbent article according to claim 1 , wherein the recess is configured such that the opposing edges of the recess at the rear transverse edge of the absorbent core are drawn towards each other via the elastic element when the absorbent article is secured to the wearer.
17. The absorbent article according to claim 1 , wherein the absorbent core includes an upper storage layer and a lower storage layer, and the elastic element is joined between the backsheet and the lower storage layer.
18. An absorbent article comprising:
a topsheet, a backsheet and an absorbent core placed therebetween, a front and a rear transverse edge, two longitudinal edges, and a transverse centerline which divides the article into a front end portion adapted to lie adjacent to or in contact with a wearer's abdomen when in use, and a rear end portion adapted to lie adjacent to or in contact with the wearer's backside when in use, said absorbent core having two longitudinal edges, a front transverse edge, and a rear transverse edge,
wherein the rear transverse edge of the absorbent core possesses a recess with at least one pair of opposing edges, the recess forms a pocket for receiving and storing faeces deposited in the article's rear end portion, the pocket's extension is defined by the edges of the recess, and the topsheet of the absorbent article is fixed directly to the backsheet in the recess, and
an elastic element is arranged to extend substantially across the recess between its opposing edges in a direction parallel to the transverse centerline of the article, the elastic element directly attached to the opposing edges of the recess.
