To the edge flowing of absorbent cores 120, it could be contacted with elastic component after sanguineous infiltration absorbent cores 120, avoid side leakage.
The major advantage of sanitary napkin 100 provided by the embodiments of the present application is:
Absorbent cores 120 absorb a large amount of menses, after menses flow to third end 121 or the 4th end 122, inhale body by the first side
130 or second side inhale body 140 adsorb, avoid side leakage.
First side suction body 130 encloses first be set as with the first end 111 of egative film 110 jointly and is isolated 113；First isolation road
113 isolation menses avoid menses from inhaling body 130 from the first side and lead by the first end 111 that the first isolation road 113 flow to egative film 110
Cause side leakage.
In addition, the first isolation road 113, which inhales the first side, has gap between body 130 and egative film 110, air can be between being somebody's turn to do
Gap, the second isolation road 114 is isolated in 113 with first is full of air, and body 130 is inhaled in the first side and second side is inhaled in body 140 and is full of
Absorbing medium, so Jie different for the propagation medium through pigr molecule, different from the first isolation road 113 of body 130 is inhaled in the first side
The viscosity of confrontation menses is not identical, so stress of the menses in two regions is different, menses inhale body 130 and first in the first side
The first side can be initially entered when 113 boundary of road is isolated inhale body 130 and the infiltration saturation of body 130 is inhaled into first side, in addition, menses are from first
