Abstract

An absorbent article comprising: a backsheet having a user-facing side, a garment-facing side, two longitudinal sides, a first transverse edge, a first waist region located along the first transverse edge, a second transverse edge, and a second waist region located along the second transverse edge. The absorbent article includes an inner layer covering at least a part of the user-facing side of the backsheet, an absorbent core located adjacent the user facing side of the backsheet, and a mechanical fastening system. The fastening system comprises at least one hook-type fastening member located in the second waist region and extending transversely beyond one longitudinal side, and an extensible landing member located in the first waist region for mechanically engaging with the hook-type fastening member. The landing member is formed from an extension of the inner layer which extends beyond the front transverse edge of the backsheet.

Claims

1. An absorbent article comprising:

a backsheet having a user facing side, a garment facing side, two longitudinal sides, a first transverse edge, a first waist region located along the first transverse edge, a second transverse edge, a second waist region located along the second transverse edge, a first section having a first section edge and a second section joined to the first section, the second section extending longitudinally outwardly from the first section edge and comprising a different material from the first section,

an absorbent core located adjacent the user facing side of the backsheet, and

a mechanical fastening system comprising;

at least one hook-type fastening member located in the second waist region and extending transversely beyond one longitudinal side, and

an extensible landing member located in the first waist region for mechanically engaging with the hook-type fastening member, the landing member being formed from a portion of the second section of the backsheet which is located in the first waist region and which extends longitudinally outwardly from the first section of the backsheet.

2. The absorbent article of claim 1 wherein the landing member is extensible by at least 5%.

3. The absorbent article of claim 1 wherein the landing member is extensible by at least 15%.

4. The absorbent article of claim 1 wherein the landing member is extensible in the direction of the front transverse edge.

5. The absorbent article of claim 1 wherein the landing member comprising an elastic loop-type material which is elastically extensible between 5% and 60% at a force of between 30 and 280 grams per inch.

6. The absorbent article of claim 1 wherein the landing member comprises a laminate of a first layer of loop-type material and a second, elastomeric layer laminated to the first layer of loop-type material.

7. The absorbent article of claim 1, wherein the length of the landing member is at least one third of the length of the first transverse edge.

8. The absorbent article of claim 1 further including a first waist elastic element located in the first waist region.

9. The absorbent article of claim 8 wherein the landing member is contracted by the waist elastic element.

10. The absorbent article of claim 8 wherein the first waist elastic element includes a pre-stretched member.

11. The absorbent article of claim 1 wherein the landing member is elastically extensible.
