Abstract

The present invention relates to an absorbent disposable article, such as a sanitary napkin, a panty protector, or a diaper. The article includes at least two generally flat, flexible bodies which include absorbent material and which, in a packaging state, can lie against one another with first flat sides which are intended to face toward the wearer when the article is in use. Two neighboring bodies of the article are mutually joined along a first common edge which forms a folding line around which the bodies can be folded out from their packaging state and which includes an arcuate section which, in the packaging state of the article, is arched toward a second opposing edge of the bodies.

Claims

1. An absorbent disposable article, comprising:

at least two generally flat, flexible bodies, each of the bodies having a flat side for facing toward a wearer when the article is in use;

the bodies include absorbent material;

in a packaging state the flat sides of the bodies lie against one another;

the at least two bodies of the article are mutually joined along a common edge which forms a folding line around which the bodies can be unfolded from their packaging state; and

the common edge includes a first arcuate section which, in the packaging state of the article, is arched toward a second opposing edge of each of the bodies.

2. An article according to claim 1, wherein the bodies are mirror-symmetrical in a longitudinal direction of the article.

3. An article according to claim 2, wherein the common edge of the bodies is S-shaped.

4. An article according to claim 3, wherein the bodies are comprised of an outer, liquid-impermeable casing material, an inner, liquid-permeable casing material which is intended to lie nearest the wearer'"'"'s body when the article is in use, and said absorbent material is in the form of an absorbent pad enclosed between the casing sheets.

5. An article according to claim 2, wherein the bodies are comprised of an outer, liquid-impermeable casing material, an inner, liquid-permeable casing material which is intended to lie nearest the wearer'"'"'s body when the article is in use, and said absorbent material is in the form of an absorbent pad enclosed between the casing sheets.

6. An article according to claim 5, wherein the bodies are mirror-symmetrical, the common edge is S-shaped, and the common edge includes a second arcuate section, the first arcuate section and the second arcuate section forming the S-shape and being mirror-symmetrical in relation to a line passing through ends of the sections.

7. An article according to claim 2, wherein the bodies are mirror-symmetrical, the common edge is S-shaped, and the common edge includes a second arcuate section, the first arcuate section and the second arcuate section forming the S-shape and being mirror-symmetrical in relation to a line passing through ends of the sections.

8. An article according to claim 1, wherein the common edge of the bodies is S-shaped.

9. An article according to claim 8, wherein the bodies are comprised of an outer, liquid-impermeable casing material, an inner, liquid-permeable casing material which is intended to lie nearest the wearer'"'"'s body when the article is in use, and said absorbent material is in the form of an absorbent pad enclosed between the casing sheets.

10. An article according to claim 1, wherein the bodies are comprised of an outer, liquid-impermeable casing material, an inner, liquid-permeable casing material which is intended to lie nearest the wearer'"'"'s body when the article is in use, and said absorbent material is in the form of an absorbent pad enclosed between the casing sheets.

11. An article according to claim 10, wherein the bodies are mirror-symmetrical, the common edge is S-shaped, and the common edge includes a second arcuate section, the first arcuate section and the second arcuate section forming the S-shape and being mirror-symmetrical in relation to a line passing through ends of the sections.

12. An article according to claim 1, wherein the bodies are mirror-symmetrical, the common edge is S-shaped, and the common edge includes a second arcuate section, the first arcuate section and the second arcuate section forming the S-shape and being mirror-symmetrical in relation to a line passing through ends of the sections.
