Abstract

An absorbent article which can effectively widen absorbing area of excretion liquid at a center portion of the absorbent article, is provided. Divided absorbent elements are formed dividingly on both of a center line. The divided absorbent elements are fixed on a back sheet at positions of compressed portions, and inner side end portions of the divided absorbent elements are taken as free ends. Upon use of a sanitary napkin, by bending the sanitary napkin in response to exertion of compressing force F from femoral parts, the divided absorbent elements are raised so that menstrual blood can be absorbed not only through inner surfaces but also through outer surfaces. Therefore, absorbing area can be greater than that of the conventional sanitary napkin, and side leakage can be successfully prevented.

Claims

1. An absorbent article provided with an absorbent element absorbing and holding a liquid, on a flat base and formed into a longitudinally elongated shape, comprising:

a cushion layer forming said base;

divided absorbent elements forming said absorbent element and dividedly formed on both sides of a center line extending in a longitudinal direction of said absorbent article;

inner side end portions of respective divided absorbent elements located in opposition across said center line; and

compressed portions located at positions away from said center line, formed by compressing said divided absorbent elements and said cushion layer together and having portions extended continuously or aligned in said longitudinal direction;

each divided absorbent element being deformable to move said inner side end portions away from said cushion layer about said compressed portions.

2. An absorbent article as set forth in claim 1, wherein each divided absorbent element has a divided absorbent layer and a liquid permeable surface sheet covering said divided absorbent layer.

3. An absorbent article as set forth in claim 1, wherein said cushion layer is an absorbent layer absorbing and holding the liquid.

4. An absorbent article as set forth in claim 1, wherein said compressed portion is formed surrounding a predetermined area of said absorbent article.

5. An absorbent article as set forth in claim 1, wherein longitudinally extending elastic members are provided in respective divided absorbent elements.

6. An absorbent article as set forth in claim 1, wherein respective divided absorbent elements are bent to place said inner side end portions toward inner surface side at positions between said inner side end portions and said compressed portion.

7. An absorbent article as set forth in claim 1, wherein a thinned portion is provided in said cushion layer along said center line.

8. An absorbent article as set forth in claim 1, wherein each divided absorbent layer is formed with a plurality of laterally extending absorbent layers.

9. An absorbent article as set forth in claim 1, which is a sanitary napkin.
