Abstract

Provided is an absorptive article having absorption elements capable of following the wearer'"'"'s body of a user. This absorptive article comprises at least a generally rectangular base absorption element, a top absorption element disposed on one surface of the base absorption element at substantially lateral center of the base absorbent and along the longitudinal direction of the base absorbent, and a fixing part for fixing the base absorption element to the top absorption element so that at least one end of the top absorption element in the longitudinal direction thereof is made to be a free end. A locking part is provided on the base absorption element side contact surface of the top absorption element near the free end. The locking part is locked to the base absorption element at a position where the top absorption element is so moved as to extend along the gluteal cleft of the user.

Claims

1. An absorbent article comprising:

a first absorbent body of substantially rectangular shape;

a second absorbent body arranged along a longitudinal direction of the first absorbent body on a skin contacting side of the first absorbent body;

a fixing portion that fixes the first absorbent body and the second absorbent body such that at least one edge of the second absorbent body in the longitudinal direction is a free end; and

a locking portion that is arranged on a skin noncontacting side opposite to the skin contacting side of the second absorbent body and can lock the first absorbent body and the second absorbent body.

2. The absorbent article according to claim 1, wherein

the absorbent article has a front edge serving as an outer edge in the longitudinal direction and close to a first position that contacts an excretion area in a state of wearing on a wearing target, and a rear edge far from the first position;

and

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

3. The absorbent article according to claim 1, wherein the locking portion is arranged on a side of the free end.

4. The absorbent article according to claim 1, wherein

the first absorbent body comprises a central portion where the second absorbent body can be arranged on a surface thereof on which the second absorbent body is arranged,

the central portion comprises a first absorbent body side surface sheet arranged so as to cover a top surface of the central portion, and

the first absorbent body side surface sheet is formed of a non-woven fabric that can be engaged with the locking portion.

5. The absorbent article according to claim 1, wherein an elastic member is arranged on the skin contacting side of the first absorbent body side surface sheet at a rear edge side of the first absorbent body.

6. The absorbent article according to claim 1, further comprising a handle portion at the free end in the second absorbent body.

7. The absorbent article according to claim 6, wherein flexural rigidity (B) of the handle portion is 0.1 to 1.2 (10⁻

4N·

m²/m).

8. The absorbent article according to claim 6, wherein flexure recovery (2 HB) of the handle portion is no greater than 10 (10⁻

2N·

m²/m).

9. The absorbent article according to claim 6, wherein the handle portion is arranged substantially at a center in a width direction of the first absorbent body, in a state where the handle portion is arranged along a central portion, where the second absorbent body is arranged, in the first absorbent body.

10. The absorbent article according to claim 6, wherein a top surface of the handle portion is formed in a concave and convex shape.

11. An absorbent article comprising:

a first absorbent body of substantially rectangular shape;

a second absorbent body arranged along a longitudinal direction of the first absorbent body on a skin contacting side of the first absorbent body;

a fixing portion that fixes the first absorbent body with the second absorbent body such that at least one end in the longitudinal direction of the second absorbent body is a free end; and

a locking portion that is arranged on a skin non-contacting side which is a face of an opposite side to the skin contacting side of the second absorbent body, is covered by the first absorbent body in a state in which the second absorbent body is not spaced apart from the first absorbent body, and is exposed in a state in which the second absorbent body is spaced apart from the first absorbent body.
