Abstract

The invention relates to a disposable article having a longitudinal direction, a longitudinal center line and a transverse direction, wherein the article has a first and a second longitudinal edge, a first and a second transverse edge, wherein the article comprises a first covering layer comprising a first surface intended to face towards the user and a second surface intended to face away from the user in use, wherein at least a first and a second fixing member comprising hook elements are arranged on the first surface close to the first transverse edge, wherein the first fixing member is arranged close to the first longitudinal edge and the second fixing member is arranged close to the second longitudinal edge, wherein substantial parts of the first surface are compatible with the hook elements.

First claim

The invention claimed is:

1. A disposable article having a longitudinal direction, a longitudinal centre line and a transverse direction, wherein the article has a first longitudinal edge and a second longitudinal edge, a first transverse edge and a second transverse edge, wherein the article comprises a first covering layer comprising a first surface configured to face towards the user and a second surface configured to face away from the user in use, wherein at least a first fixing member and a second fixing member comprising hook elements are arranged on the first surface closer to the first transverse edge than to the second transverse edge, wherein the first fixing member is arranged closer to the first longitudinal edge than to the second longitudinal edge, and the second fixing member is arranged closer to the second longitudinal edge than to the first longitudinal edge,
wherein parts of the first surface are mechanically compatible with the hook elements,
wherein the article comprises a liquid-impermeable second covering layer arranged on the second surface of the first covering layer oriented away from the user,
wherein an absorbent body is arranged between the first covering layer and the liquid-impermeable second covering layer and wherein the first covering layer is liquid-permeable, wherein the first surface of the first covering layer comprises first and second areas respectively connected to a corresponding one of the first and second fixing members, wherein each of said first and second areas has a lower mechanical compatibility with the respective hook elements of the corresponding one of the first and second fixing members than adjacent parts of the first surface of the covering layer.

2. The disposable article according to claim 1 , wherein the areas having a lower mechanical compatibility with the respective hook elements have an extension in the longitudinal direction of the article from the first transverse edge to the opposing transverse edge of 10-20% of the outstretched length of the article, wherein the first area has an extension in the transverse direction of the article between the first longitudinal edge and the longitudinal centre line of the article of 25-50% of the outstretched length of the first transverse edge and wherein the second area has an extension in the transverse direction of the article between the second longitudinal edge and the centre line of the article of 25-50% of the outstretched length of the first transverse edge.

3. The disposable article according to claim 1 , wherein the areas lack mechanical compatibility with the hook elements.

4. The disposable article according to claim 1 , wherein the article is configured to be attached detachably to a separate belt arranged around a user's waist, wherein the article comprises a third and a fourth fixing member comprising hook elements arranged on the first surface closer to the second transverse edge than to the first transverse edge, wherein the third fixing member is arranged closer to the second longitudinal edge than to the first longitudinal edge and the fourth fixing member is arranged closer to the first longitudinal edge than to the second longitudinal edge, wherein the first surface of the first covering layer comprises a third area connected to the third fixing member and a fourth area connected to the fourth fixing member, wherein said areas have lower mechanical compatibility with the respective hook elements than adjacent parts of the first surface of the first covering layer.

5. The disposable article according to claim 4 , wherein the third and fourth areas having lower mechanical compatibility with the respective hook elements have an extension in the longitudinal direction of the article from the second transverse edge to the opposing transverse edge of 10-20% of the outstretched length of the article, wherein the third area has an extension in the transverse direction of the article between the second longitudinal edge and the longitudinal centre line of the article of 25-50% of the outstretched length of the second transverse edge and wherein the fourth area has an extension in the transverse direction of the article between the first longitudinal edge and the centre line of the article of 25-50% of the outstretched length of the second transverse edge.

6. The disposable article according to claim 4 , wherein the third and fourth areas lack mechanical compatibility with the hook elements.

7. The disposable article according to claim 4 , wherein the third and fourth areas having lower mechanical compatibility with the respective hook elements have an extension in the longitudinal direction of the article from the second transverse edge to the opposing transverse edge of 15% of the outstretched length of the article, wherein the third area has an extension in the transverse direction of the article between the second longitudinal edge and the longitudinal centre line of the article of 37% of the outstretched length of the second transverse edge and wherein the fourth area has an extension in the transverse direction of the article between the first longitudinal edge and the centre line of the article of 37% of the outstretched length of the second transverse edge.

8. The disposable article according to claim 1 , wherein the article comprises a belt arranged connected to the article's second transverse edge, wherein the belt is configured to be fastened around the user's waist upon use, wherein the hook elements are configured upon use to be connected detachably to the surface of the belt oriented away from the user.

9. The disposable article according to claim 1 , wherein the first covering layer consists of a nonwoven material comprising heat-treatable synthetic fibres having loops on the first surface, wherein the loops in the respective area having lower mechanical compatibility with the respective hook elements have been reduced by heat treatment.

10. The disposable article according to claim 1 , wherein the first covering layer consists of a nonwoven material having loops on the first surface, wherein the loops in the respective area having lower mechanical compatibility with the respective hook elements have been eliminated by laminating a cover layer free of loops on the first surface in the respective area.

11. The disposable article according to claim 10 , wherein the cover layers consist of a spunbond nonwoven.

12. The disposable article according to claim 10 , wherein the cover layers consist of a plastic film.
