Abstract

A sanitary napkin (101) has a liquid-permeable top sheet (102), a liquid-impermeable back sheet (103), and an absorber (104) mounted between the top sheet (102) and the back sheet (103) and capable of absorbing bodily fluid. The sanitary napkin (101) also has insertion holes (107) provided on opposite sides in the lateral direction (W) of the sanitary napkin (101) so as to extend in the longitudinal direction (L) of the sanitary napkin (101), and long members (106) are inserted through the insides of the insertion holes (107). Each of the insertion holes (107) has an opening (108) located on the front end side (Fr) and also has a fixing portion (112) located on the rear end side (Ba). The long members (106) each have a long portion (111) inserted through the inside of the insertion holes (107) and also have a draw-out portion (109) led out from the openings (108) to the outside of the insertion holes (107). The rear ends of the long portion (111) are fixed to the fixing portion (112).

Claims

1. An absorptive article comprising a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorber disposed between the top sheet and the back sheet, and capable of absorbing body fluid, the absorptive article having:

insertion holes positioned on both sides in the width-wise direction of the absorptive article, and extended along the longitudinal direction from the front end side of the absorptive article towards the rear end side of the absorptive article; and

long members inserted through the insertion holes, wherein each insertion hole has;

an opening positioned on the front end side of the absorptive article; and

a fixing portion positioned on the rear end side of the absorptive article;

each long member has;

a long portion inserted through each insertion hole; and

a draw-out portion continued from each long portion and drawn through each opening into the outside of each insertion hole; and

the rear end of the long portion positioned on the rear end side of the absorptive article is fixed to the fixing portion.

2. The absorptive article according to claim 1, wherein

the insertion holes are formed on both sides in the width-wise direction of the absorber, between the top sheet and the back sheet.

3. The absorptive article according to claim 1, wherein

the top sheet has, at least in portions on the left-and-right sides thereof, side-sheets bonded thereto, and

the insertion holes are provided between the side-sheets and the back sheet.

4. The absorptive article according to claim 1, wherein

the long member is formed by a single string,

the string being turned around on the rear end side of the absorptive article, and

both ends of the string are respectively drawn out from the openings on the front end side of the absorptive article.

5. An absorptive article comprising a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorber disposed between the top sheet and the back sheet, and capable of absorbing body fluid, the absorptive article having

insertion holes positioned on both sides in the width-wise direction of the absorptive article, and extended along the longitudinal direction from the front end side of the absorptive article towards the rear end side of the absorptive article;

and

long members inserted through the insertion holes, wherein each insertion hole has;

an opening positioned on the front end side of the absorptive article; and

a fixing portion positioned on the rear end side of the absorptive article;

each long member has;

a long portion inserted through each insertion hole; and

a draw-out portion continued from each long portion and drawn through each opening into the outside of each insertion hole; and

the front end of the long portion positioned on the front end side of the absorptive article is fixed to the fixing portion.

6. An absorptive article comprising a body fluid-permeable top sheet, a body fluid-impermeable back sheet, and an absorber disposed between the top sheet and the back sheet, and having a pair of leakage barrier walls provided on both sides in the width-wise direction of the absorber along the longitudinal direction, and having, between the pair of leakage barrier walls, leakage barrier trenches provided on both sides of a skin contact portion of the absorber, wherein

the leakage barrier trenches have arch-wise projected portions in both side portions in the width-wise direction of the skin contact portion, and

the absorber has compressed portions having rigidity larger than that in the region including at least skin contact portions of the leakage barrier trenches, in regions between the leakage barrier walls and the leakage barrier trenches.

7. The absorptive article according to claim 6, wherein

the compressed portions are embossed portions formed by compressing the absorber by embossing.

8. The absorptive article according to claim 6, wherein

the compressed portions are formed continuously or intermittently between a folding portion at the center of the absorptive article before being folded and packaged by unit of use, and the front end of the absorber.
