FIGS. 1 and 2 are a partially cutaway perspective view of a napkin and a sectional view taken along line XX. The napkin has a main body 1 in which a liquid-absorbent core 4 is interposed between a liquid-permeable top sheet 2 and a liquid-impermeable back sheet 3 . Body 1, the upper surface of the topsheet 2 made of a pair of right and left liquid-resistant sheet Hula
It has a top 5 . In the front and back sheets 2 and 3, the portions extending from the peripheral edge of the core 4 are joined together with the outer peripheral edge of the liquid-resistant flap 5 by a seal line 6. The main body 1 has front and rear ends 9, 10 and an intermediate portion 11, and has a center line XX that bisects the left and right, and a center line YY that bisects the front and rear. The flap 5 has an inner free edge 13 that draws a sine-curve cut line 12 along the center line XX. It gradually decreases toward 9 and 10 and overlaps each other at ends 9 and 10. The free edge portion 13 thus separated can expose the topsheet 2 so as to abut only on the wearer's vaginal opening and its vicinity. The flap 5 has a pocket 15 whose free edge 13 opens toward the center line XX, as shown in FIG.
Is formed together with the top sheet 2.

When such a napkin is worn, menstrual blood and other body fluids penetrate into the core 4 from the exposed portion of the topsheet 2 and also enter the pocket 15 from there.
And diffuses back and forth and left and right in the core 4.
In addition, body pressure is applied to the worn napkin in the vertical direction,
Once absorbed menstrual blood may flow back to the top surface of the topsheet 2. However, in this napkin, since the peripheral portion is covered with the flap 5, there is no possibility that the backflowed menstrual blood stains the skin or enhances the wet feeling. In particular, body 1
Overlap the flaps 5 at the ends 9 and 10 of the
The purpose is to increase the effect of preventing menstrual blood from flowing back
It is.
