Abstract
An absorbent structure (3) for an absorbent article has, in the longitudinal direction, a central portion (11) and two end portions (12, 13). The average density of the material in the central portion (11), at least in the dry state, is higher than the average density of the material in the end portions (12, 13), and in that the central portion (11), at least in the dry state, has a lower basis weight than the end portions (12, 13), the density and the basis weight being calculated on the basis of the entire surface area of the central portion (11) or as appropriate the entire surface area of the end portion (12, 13).
Claims18
An absorbent structure for an absorbent article, the absorbent structure comprising, in the longitudinal direction, a central portion made of a first material and two end portions made of a second material,
- an average density of the first material in the central portion, at least in a dry state, is higher than an average density of the second material in the end portions, and
- the central portion, at least in the dry state, has a lower basis weight than the end portions.
An absorbent article, which has an essentially oblong shape and comprises a liquid-permeable surface layer, a liquidtight backing layer, and, enclosed between these layers, an absorbent structure, which absorbent structure has, in the longitudinal direction, a central portion and two end portions, and an average density of a material in the central portion, at least in the dry state, is higher than an average density of a material in the end portions, and the central portion, at least in the dry state, has a lower basis weight than the end portions, the basis weight and the density being calculated on the basis of the entire surface area of the central portion and the entire surface area of the end portions.
An absorbent structure for an absorbent article, the absorbent structure comprising:
- a liquid spreading layer;
- a liquid receiving layer made of a first material is mounted to one side of the liquid spreading layer in a central portion thereof;
- two liquid storing sections made of a second material are mounted on the one side of the liquid spreading layer on opposite end portions of the liquid spreading layer, wherein the liquid receiving layer is located between the two liquid storing sections;
- an average density of the first material of the liquid receiving layer, at least in a dry state, is higher than an average density of the second material of the two liquid storing sections;
- and
- wherein the absorbent structure is thinner in the central portion where the liquid receiving layer is located than in the end portions where the liquid storing sections are located.
