Description
Technical field
This application involves amenities technical field, more particularly to a kind of absorbent article.
Background technology
Sanitary napkin is a kind of absorbent article for having and absorbing determining female physiological periodicity menses.Most of health currently on the market
Towel is structurally, include mainly face layer, sandwich layer, bottom and a pair of of flap of configuration at left and right sides of sandwich layer, wherein described
Face layer uses fibers material, blended material or general cotton material, the bottom to wrap up wood pulp using toilet paper, and the counterdie is adopted
With PE films, PE films are a kind of waterproof materials, and menses can be retained in sanitary napkin, carry out the time of tide for absorbing feminine menstrual, from
The menses of private parts outflow.The design of flap is mainly used to prevent side leakage, because during sanitary napkin use, due to human body
Activity can cause menses to be leaked out from the side of sanitary napkin, but flap in the prior art is integrally formed with bottom, material at flap
Matter is more thick and heavy, and flexibility is poor, and during sanitary napkin use, flap cannot be pasted with the clothing of user well
It closes, stationarity is poor, be easy to cause side leakage.
When menstruating women is in the hot weather a large amount of sweat of generation, since counterdie uses the impermeability of PE films, Wu Fayou
Sweat and moisture are discharged effect, lead to private parts bacteria breed, influence the health of women.In order to solve the ventilative sex chromosome mosaicism of PE films,
In the market many sanitary napkins start use PE ventilated membranes, PE ventilated membranes be will add inert material in PE master batches, such as：Carbonic acid
Calcium, then stretched formation micropore keeps the film ventilative in process of production, but the Air permenbility very little of this micropore, whole
Air permeability also has considerable room for improvement.In order to improve the overall air permeability energy of product, also there are a small number of sanitary napkins on the market now
Counterdie is done using non-woven fabrics, the air permeability effect of non-woven fabrics is far superior to PE films, but the maximum drawback that non-woven fabrics does counterdie is nothing
Woven fabric cannot effectively stop that the leakage of menses, the basic of antiseep cannot obtain effective solution.

Cloth or water repellent spunlace non-woven cloth etc., the second water repellent nonwovens 7 can not only enhance the pliability of product and use feel, can be with
It fits together with the first water repellent nonwovens 5, pass material 6 and reaches better leak resistance.
In the embodiment of the present application, the first water repellent nonwovens 5, pass material 6 and 7 heat seal of the second water repellent nonwovens or glue are connected
It is connected together, two layers of water-proof material realizes double leak-proof, so that product is had better anti-leakage and will not reduce sanitary napkin
Gas permeability.
Referring to Fig. 3, in one embodiment of the application, the bottom membrane further includes absorbing material 8, and the absorbing material 8 is located at
Under first water repellent nonwovens 5 and on the male and fomale(M＆F) of the pass material 6, height may be used in the absorbing material 8
Molecular material and/or absorption fiber make, and can absorb the liquid through first water repellent nonwovens 5 so that the counterdie
Layer has better leak resistance.
In the embodiment of the present application, together with the first water repellent nonwovens 5, absorbing material 8 and 6 heat seal of pass material, absorb
Material 8 can effectively absorb through the first water repellent nonwovens 5 liquid and absorb it is non-be discharged using position liquid (such as
The vapor of user's discharge), it is effective to ensure that the dry-ness of product, the first water repellent nonwovens 5 and pass material 6 protect again
Demonstrate,prove the gas permeability and anti-leakage of the bottom membrane.
Referring to Fig. 4, in one embodiment of the application, the flap 2 includes the first flap 10 and the second flap 11, and described first
Flap 10 and second flap 11 are symmetrically arranged the both sides in the bottom membrane in the width direction.Wherein, described first
The shape of flap 10 and second flap 11 can be identical, or the shape used of working in coordination.
The flap 2 of the embodiment of the present application is made of individual flexible material, and then gluing subtracts on the bottom membrane
Lack the waste of material that flap 2 is an integral structure with bottom membrane, and makes the shape of sanitary napkin relatively beautiful.The flap
2 use individual material, can also be avoided during sanitary napkin use because flap 2 is thicker during user moves
The case where displacement for causing sanitary napkin, occurs, and can also reduce the possibility that sanitary napkin deforms upon so that sanitary napkin has more
Good leak resistance.
In practical application, flap 2 or integrated formed structure are arranged under the sandwich layer, the bottom membrane it
On.

The side of film layer in the width direction.
The interconnecting piece 12 is fixed between the sandwich layer and the bottom membrane, and the extension 13 extends the counterdie
The side of layer in the width direction, and the interconnecting piece 12 is located at the intermediate region of the bottom membrane along its length.
In the embodiment of the present application, first flap 10 and second flap 11 are individually fixed in the bottom membrane along wide
The both sides for spending direction, when in use lateral leakage occurs for the sanitary napkin, first flap 10 and described second
Partially liq can be drained among the sandwich layer and the bottom membrane by the interconnecting piece 12 of flap 11, and side is prevented with certain
Leak effect.
In the embodiment of the present application, first water repellent nonwovens 5 may include water repellent hot-wind nonwoven cloth, the anti-sticking nonwoven of water repellent
Cloth or water repellent spunlace non-woven cloth.
In order to improve gas permeability, safety and the comforts of use of sanitary napkin, the application is used pass material 6 and the
One water repellent nonwovens are 5 compound, the second water repellent nonwovens 7 will be added between pass material 6 and the first water repellent nonwovens 5, by pass
Absorbing material 8 etc. is added between material 6 and the first water repellent nonwovens 5 and does the design of bottom membrane structural improvement, solves sanitary napkin bottom
The problem of film leakage, and can also ensure good air permeability effect.2 structure of flap of sanitary napkin, the prior art are improved simultaneously
In flap structure be in face layer and bottom membrane is horizontal upwardly extends, then extra remaining sapwood material is cut off by shape cutter, and
The application optimizes the structure of flap 2, further reduced sanitary napkin leakage on the basis of reducing waste of material, environmental protection and saving
Probability.
The application preferred embodiment and embodiment are explained in detail above in conjunction with attached drawing, but the application
The above-described embodiment and examples are not limited to, within the knowledge of those skilled in the art, can also not taken off
It is made a variety of changes under the premise of conceiving from the application.
