Abstract

Provided is an absorptive article having absorption elements capable of following the body of a user. This absorptive article (1) comprises a generally rectangular base absorption element (2), a top absorption element (3) disposed on one surface of the base absorption element (2) at substantially lateral center of the base absorption element (2) and along the longitudinal direction of the base absorption element (2), and a fixing part (4) for fixing the base absorption element (2) to the top absorption element (3) so that at least one end of the top absorption element (3) in the longitudinal direction thereof is made to be a free end (31). A temporary locking part (5) for restricting the movement of the top absorption element (3) is provided on the top absorption element (3) near a free end part (32) thereof at least before application of the absorptive article to the body of the user.

Claims

1. An absorbent article comprising:

a substantially rectangular first absorbent core;

a second absorbent core, which is provided on a skin contacting side of the first absorbent core along a longitudinal direction of the first absorbent core;

a fixing portion, which fixes the first absorbent core and the second absorbent core so that at least one end of the second absorbent core in the longitudinal direction serves as a free end; and

temporary fixing portions, which are formed between the fixing portion and the free end.

2. The absorbent article of claim 1, wherein

the absorbent article comprises a front edge, which is an outer edge in the longitudinal direction and close to a first position contacting with an excretion area in a state attached to an attaching target, and a rear edge, which is far from the first position;

wherein

the fixing portion is formed between the first position and the front edge.

3. The absorbent article of claim 1, wherein

the temporary fixing portions are formed on the free end side of the second absorbent core.

4. The absorbent article of any of claim 1, comprising

a handle part, which is formed at the free end of the second absorbent core.

5. The absorbent article of any of claim 1, wherein

the second absorbent core comprises a locking portion, which is provided on the free end side;

and

the locking portion also serves as the temporary fixing portions.

6. The absorbent article of claim 5, wherein

in an attached state,

the locking portion locks the free end further on an outer edge side in the longitudinal direction of the first absorbent core than a position when the first absorbent core and the second absorbent core are formed into an approximate flat plane.

7. The absorbent article of claim 5, wherein

when the absorbent article is provided between the attaching target and garment which is provided so as to cover the attaching target, and

the locking portion is locked on the inside of the garment, or locked on the outside of the garment by folding back the second absorbent core.

8. The absorbent article of any of claim 1, wherein

the second absorbent core has a length in a width direction orthogonal to the longitudinal direction in a range from 40% to 90% of length in the width direction of the first absorbent core.

9. The absorbent article of claim 8, wherein

the second absorbent core has leakage-preventing wall materials provided so as to extend in the longitudinal direction in both side portions which are both ends in the width direction.

10. An absorbent article, which is a substantially rectangular shape and attached to an attaching target having an excretion area, comprising:

a substantially rectangular first absorbent core;

a second absorbent core, which is provided on a skin contacting side of the first absorbent core along a longitudinal direction of the first absorbent core; and

a fixing portion, which fixes the first absorbent core and the second absorbent core so that one edge of the second absorbent core serves as a free end;

wherein

the fixing portion is formed on a rear edge side far from a first position which makes contact with the excretion area in the longitudinal direction while the absorbent article is attached to the attaching target; and

the free end is provided on a front edge side close to the first position in the longitudinal direction.

11. An absorbent article, which is attached to an attaching target having an excretion area, comprising:

a substantially rectangular first absorbent core;

a second absorbent core, which is provided on a skin contacting side of the first absorbent core along a longitudinal direction of the first absorbent core; and

a fixing portion, which fixes the first absorbent core and the second absorbent core;

wherein

the fixing portion is formed at a position separated from respective ends of the second absorbent core in the longitudinal direction; and

the second absorbent core includes a first free end, which is provided on a front edge side close to a first position which makes contact with the excretion area in the longitudinal direction while the absorbent article is attached to the attaching target, and a second free end, which is provided on a rear edge side far from the first position in the longitudinal direction.
