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 having a longitudinal direction;

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

a permanent fixing portion that permanently fixes the first absorbent body and the second absorbent body at a first end of the second absorbent body, wherein the second absorbent body has a second end opposite to the first end in the longitudinal direction and free of permanent attachment to the first absorbent body; and

a locking portion that is arranged between the permanent fixing portion and the second end on a skin non-contacting side opposite to the skin contacting side and temporarily locks the first absorbent body and the second absorbent body,

wherein

the first absorbent article has

a front edge and a rear edge opposite to the front edge in the longitudinal direction, and

a first position adapted to be in contact with an excretion area of a wearer in use,

the first position being arranged closer to the front edge than the rear edge,

the fixing portion is between the first position and the front edge, and

the second absorbent body projects in the longitudinal direction outwardly from said front and rear edges of the first absorbent portion, respectively.

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

3. The absorbent article according to claim 1, wherein

the first absorbent body comprises a central portion and a first absorbent body side surface sheet covering the central portion, and

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

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

5. The absorbent article according to claim 4, wherein flexural rigidity of the handle portion is 0.1 to 1.2 (10⁻

4N·

6. The absorbent article according to claim 4, wherein flexure recovery of the handle portion is no greater than 10 (10⁻

2N·

m²/m).

7. The absorbent article according to claim 4, wherein the second absorbent body including the handle portion is arranged substantially at a center of the first absorbent body in a width direction perpendicular to the longitudinal direction.

8. The absorbent article according to claim 1, wherein the locking portion includes a hook fastener having a plurality of pins directed to a predetermined direction.

9. The absorbent article according to claim 1, wherein a width of the second absorbent body in a width direction perpendicular to the longitudinal direction is substantially uniform in the longitudinal direction.

10. The absorbent article according to claim 1, wherein the second absorbent body has a compression bonded portion where the first absorbent body and the second absorbent body are compressed and bonded together, said compression bonded portion being opposite to the second end of the second absorbent body in the longitudinal direction.

11. The absorbent article according to claim 10, wherein the permanent fixing portion is between said compression bonded portion and the temporary fixing portion.
