Abstract

An absorbent product, such as a sanitary napkin, an incontinence protector or a panty liner. The product has an essentially elongated shape with a longitudinal direction and a transverse direction. The product has two long sides, two short sides, two end parts, a center part situated between the end parts and an absorption body. The product in the longitudinal direction of the product has elongated, curved compressions which have a bending radius of 300-450 mm, preferably 320-360 mm.

Claims

1. An absorbent product comprising:

an essentially elongated shape with a longitudinal direction and a transverse direction, two long sides, two short sides, two ends parts, a center part between the two end parts, an absorption body, and elongated, curved compressions in the longitudinal direction of the product,

wherein the compressions have a bending radius of 300-450 mm.

2. The absorbent product according to claim 1, wherein the product has a longitudinal center line and the compressions are arranged on both sides of said center line so that respective end parts of said curved compressions are at a greater distance from the center line than respective center parts of said curved compressions.

3. The absorbent product according to claim 2, wherein the product has two compressions arranged one on each side of the center line.

4. The absorbent product according to claim 3, wherein the smallest distance between the compressions is 25-35 mm.

5. The absorbent product according to claim 4, wherein the smallest distance between the compressions is 27.5-32.5 mm.

6. The absorbent product according to claim 1, wherein the smallest distance between a compression and the closest of the long sides of the product is 5-20 mm.

7. The absorbent product according to claim 6, wherein the smallest distance between a compression and the closest of the long sides of the product is 10-15 mm.

8. The absorbent product according to claim 1, wherein a length of each of the compressions is at least 50% of a length of the absorption body.

9. The absorbent product according to claim 1, wherein a length of the compressions is 50-75% of a length of the absorption body.

10. The absorbent product according to claim 1, wherein a length of the compressions is 60-85% of a length of the absorption body.

11. The absorbent product according to claim 1, wherein the compressions are united to form a coherent compression running around the product.

12. The absorbent product according to claim 1, wherein the compressions have a bending radius of 320-360 mm.
