Description
Technical field
The utility model is related to hygiene article sector more particularly to a kind of sanitary napkins.
Background technology
Disposable absorbent article when sanitary napkin is female menstrual period for absorbing menses in use usually can be because of outer
The effect of power causes sanitary napkin to deform, and there is a phenomenon where liquid side leakages, to make clothing dirty, brings women and greatly perplexs.City
The generation of common sanitary napkin side leakage in order to prevent on field, general using the absorptive core for having more adsorption capacity, sanitary napkin both sides are set
Flank enhancing leakproof is set, and in several longitudinal diversion trenches of sanitary napkin surface setting, to guide liquid, although these lateral leakage protection are set
Set certain effect that plays, but also only with respect to it is static when effect can be quite a lot of.
The Chinese patent application publication No. CN106361502A that on February 01st, 2017 announces discloses a kind of sanitary napkin, wraps
Include egative film, absorptive core, the bottom end of egative film has been provided with the adhesive layer of cementation, further include top flat, absorber clad and
It is capable of the leakage barriers of barrier liquid diffusion, leakage barriers coat the both sides of absorptive core；Top flat connect to form cladding absorption with egative film
The cavity of core and leakage barriers；Absorber clad is arranged in the cavity that top flat and egative film are formed, and coats absorptive core.This
The sanitary napkin provided is invented, in use, sanitary napkin is fixed to the position needed by the adhesive layer of egative film.Above-mentioned sanitary napkin is logical
It crosses and is provided with the leakage barriers of barrier liquid diffusion in the both sides of absorptive core, reduce the generation of side leakage, improve the use of sanitary napkin
Comfort.
But the present inventor has found anti-side leakage effect and the city of above-mentioned sanitary napkin when actual user's using effect is investigated
Most of sanitary napkin on field is without too big improvement.The present inventor has found after analyzing its reason, due to the absorption of sanitary napkin
Core is very thin, and absorptive core expands after absorbing menses, and the absorptive core thickness after expansion is the absorptive core thickness before expansion
Several times, at this time leakage barriers can not coat the both sides of absorptive core, sanitary napkin still can side leakage, and the suction of above-mentioned sanitary napkin
After receiving core absorption menses, if after being squeezed by external force liquid reverse osmosis can occur for absorptive core, it is unfavorable for women's health.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes a kind of sanitary napkins, solve existing sanitary napkin lateral leakage protection
The problem of effect is poor, and absorptive core can occur liquid reverse osmosis, be unfavorable for women's health after being squeezed by external force.
To achieve the above object, the utility model uses following technical scheme：A kind of sanitary napkin, including from top to bottom according to
The secondary folded soft surface layer of anti-reverse osmosis, clean paper layer, absorbent core and the ventilative leakproof bottom film set, further includes hydrophobic leakproof side,
The hydrophobic leakproof side is coated on the side on anti-reverse osmosis soft surface layer and ventilative leakproof bottom film, the absorbent core bottom also between
Every being provided with a plurality of super water-absorbent absorbent cores, each super water-absorbent absorbent cores are along the central axes direction of vertical absorbent core
Setting, the areas of each super water-absorbent absorbent cores from the middle part of absorbent core to both sides in gradually increasing, the absorbent core
It is all provided between two neighboring super water-absorbent absorbent cores that there are one hydrophobicity cores on body bottom.
Further, the absorbent core includes from top to bottom folding a plurality of absorbed layers set successively, each absorption
The water absorbing properties of layer are from top to bottom sequentially increased.
Further, the side on the soft surface layer of anti-reverse osmosis is equipped with the choked flow slot for preventing liquid from flowing out, the choked flow
Slot is arranged along the edge on hydrophobic leakproof side.
By using preceding solution, the utility model has the beneficial effects that：This sanitary napkin passes through in ventilative anti-bottom drain
The side coated by hydrophobic leakproof side of film and the soft surface layer of anti-reverse osmosis, effectively prevent liquid side leakage, and at the bottom of absorbent cores core
Portion is arranged at intervals with a plurality of super water-absorbent cores, and the area of each super water-absorbent absorbent cores is in from absorbent core middle part to both sides
It gradually increases, hydrophobicity core is equipped between adjacent super water-absorbent core, liquid is made not to be trapped in the middle part of sanitary napkin；Into one
Step, a plurality of absorbed layers of absorbent core are from top to bottom folded and are set, and the water absorbing properties of absorbed layer from top to bottom increase successively
Greatly, liquid reverse osmosis is prevented；Further, choked flow slot is arranged by the side on the soft surface layer of anti-reverse osmosis, further prevents liquid
Side leakage.
Description of the drawings
Fig. 1 is the planar structure schematic diagram of the utility model embodiment；
Fig. 2 is the cross-sectional view of the utility model embodiment；
Fig. 3 is the absorbent core bottom substance schematic diagram of the utility model embodiment.
Specific implementation mode
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
With reference to figure 1, Fig. 2 and Fig. 3, the present embodiment provides a kind of sanitary napkins, including the soft surface layer 1 of anti-reverse osmosis, clean paper layer
2, absorbent core 3, ventilative leakproof bottom film 4, hydrophobic leakproof side 5 and super water-absorbent core group 6.The soft surface layer of anti-reverse osmosis
1, clean paper layer 2, absorbent core 3 and ventilative leakproof bottom film 4 are from top to bottom folded and are set successively, and the hydrophobic leakproof side 5 is coated on
The side on anti-reverse osmosis soft surface layer 1 and ventilative leakproof bottom film 4, limitation liquid outflow, plays a part of to prevent side leakage；The anti-reverse osmosis
1 side of soft surface layer is equipped with the choked flow slot 11 for preventing liquid from flowing out, and the choked flow slot 11 is arranged along the edge on hydrophobic leakproof side 5,
It can effectively prevent liquid side leakage；The absorbent core 3 includes from top to bottom folding the absorbed layer 31 set, absorbed layer 32 successively and inhaling
Layer 33 is received, the absorbed layer 31, absorbed layer 32 and absorbed layer 33 are mixed by Time of Fluff Slurry and hydroscopic high-molecular resin (calling SAP in the following text)
