Specific embodiment

Fig. 1 and Fig. 2 are please referred to, absorbent article 100 provided by the first preferred embodiment of the invention includes liquid permeable Top flat 10, the egative film 30 of impermeable liquid and the absorber 20 being folded between top flat 10 and egative film 30.The absorption Product 100 has two opposed ends, is front end 101 and rear end 102 respectively, and be folded between front end 101 and rear end 102 Middle area, when using the absorbent article, the front end 101 is located at the front of user, after the rear end 102 is located at user Portion is usually contacted with the butt crack of user, and the middle area is located at user's body fluid and excludes below position and accept to absorb big portion Divide the body fluid of discharge.The top flat 10 includes three regions, is main uptake zone 11, secondary uptake zone 12 and comfort zone 13 respectively.

The main uptake zone 11 is located substantially at the middle section of the top flat 10, that is, is located substantially at the centre of absorbent article 100 In area, which can be discharged position with the body fluid of user and directly contact, for directly absorbing the body fluid of user's discharge.This reality It applies in example, the main uptake zone 11 is wide and generally long and narrow along the length direction of top flat 10 shape in the narrow centre in both ends, and main The both ends of uptake zone 11 are set as arc-shaped；Front end 101 of the both ends of the main uptake zone 11 respectively close to the absorbent article 100 With rear end 102, the furthermore center line symmetrical setting on main 11 relative absorbance product of uptake zone, 100 length direction.Preferably, institute The area for stating main uptake zone 11 accounts for the 1/3-1/2 of 10 area of top flat.

The secondary uptake zone 12 is arranged adjacent to the main uptake zone 11, is permeated for absorbing from main uptake zone 11 Body fluid does the effect of further osmotic absorption.Herein it should be noted that neighbouring refer to different things or object in time, sky Between be closely connected or adjacent on position.Specifically, which can be on spatial position with main uptake zone 11 The two is connected setting, both is also possible to close to each other.

In the present embodiment, the connection of secondary uptake zone 12 is arranged in the main uptake zone 11 close to the absorbent article 100 front ends 101, the secondary uptake zone are contoured to correspond to cooperate the crescent of main 11 circular arc-shaped end of uptake zone.Preferably, institute The area for stating time uptake zone 12 accounts for the 1/6-1/4 of 10 area of top flat.

The comfort zone 13 is the other areas of top flat 10 excluded behind the main uptake zone 11 and the secondary uptake zone 12 Domain, in the present embodiment, the comfort zone 13 are looped around the periphery of the main uptake zone 11 and time uptake zone 12.

It should be understood that it is also provided with other secondary uptake zone 12 in neighbouring main 11 other positions of uptake zone, The setting position of the other secondary uptake zone 12 is not limited with shape, can do different designs according to specific product.Such as Absorbent article 200 provided by second preferred embodiment shown in Fig. 3, in the neighbouring main uptake zone 11 close to absorbent article 100 rear ends 102 are provided with other secondary uptake zone 12a, which is circumferentially positioned at main uptake zone 11 close to absorption system The periphery of 100 rear end 102 of product is substantially in V-shape；Absorbent article 300 provided by third preferred embodiment as shown in Figure 4, The secondary uptake zone 12b of similar hat-shaped is provided at rear end 102, which is arranged in main uptake zone 11.

It should be understood that the secondary uptake zone 12 can also be looped around the periphery of the main uptake zone 11, such as shown in fig. 5 Absorbent article 400 provided by 4th preferred embodiment is connected with time uptake zone 12c in the periphery of main uptake zone 11, and The secondary uptake zone 12c is looped around 11 periphery of main uptake zone.

It should be understood that the shape that the main uptake zone 11 and time uptake zone 12 on the top flat 10 are arranged is not limited to figure 1, Fig. 3, Fig. 4 and shape shown in fig. 5, in other embodiments, the main uptake zone 11 and time uptake zone 12 can also be set Count into other various rules or irregular shapes, for example, the main uptake zone 11 and time uptake zone 12 can be respectively set it is rectangular Rectangle or both, which is disposed as, with ellipse, the two is disposed as ellipse etc. or the main uptake zone 11 and time uptake zone The various shapes such as 12 asymmetric settings.

The main uptake zone 11 is the region directly contacted with the body fluid of user discharge position, into the body fluid in the region More, in order to ensure the dry and comfortable comfort of user when in use, the material of the main uptake zone 11 requires can Rapid osmotic body fluid properties.

The secondary uptake zone 12 is to do further osmotic absorption to the liquid outside main uptake zone 11, plays the work of leak-proof reinforced With the material of the secondary uptake zone 12 requires the performance that can permeate body fluid, due to body fluid pervious to the secondary uptake zone 12 Lacking compared to main uptake zone 11 is measured, so the secondary uptake zone 12 selects the material weaker compared to the permeance property of main uptake zone Matter.

Usual body fluid be discharged and fall into the main uptake zone 11 it is interior after, most body fluid all can rapid osmotic to the region And be absorbed body and sponge, small part is not entered in time 12 region of uptake zone simultaneously by the body fluid that main 11 osmotic absorption of uptake zone is fallen Be saturated and sponge, and the body fluid that can enter in the comfort zone 13 is few, thus the selection of the comfort zone 13 compared to The weak material of the permeance property of secondary uptake zone 12, and most of region is bonded the skin of user in the comfort zone 13, so The material of the secondary uptake zone 12 it is also desirable to have smoothly low friction sense, to provide user's soft comfortable feeling.

To sum up, it can satisfy that consumer is i.e. dry and comfortable and the demand of absorbent article 100 of soft comfortable, the absorbent article The requirement of the material of each region divided on 100 top flat 10 will be different.So each region divided according to top flat 10 The difference of material is required, the different zones of the top flat 10 are done into different designs to meet the different demands of user, that is, It says, the top flat 10 is designed to that descending to the permeability of liquid is successively main uptake zone 11, secondary uptake zone 12, comfort zone 13。

In order to further meet the needs of absorbent article dry and comfortable soft comfortable, each region pair on top flat 10 can control Body fluid returns infiltration rate.According to the different demands of each region, by the top flat 10 be designed to liquid to return infiltration rate ascending It is successively main uptake zone 11, secondary uptake zone 12, comfort zone 13.

In the prior art there are mainly two types of the materials of top flat 10, i.e. PE making hole film and non-woven fabrics.Below with both materials Being how to realize trizonal different demands on the top flat 10 to be described.

The first material: the material of the top flat 10 selects PE making hole film.

Through-hole is provided on the PE making hole film.The through-hole has upper end towards skin surface and opposite with upper end Lower end towards absorber 20.

Since the number of openings of the setting on top flat 10 in some region is more, the total pore volume in the region is got over Greatly, the ratio for accounting for the total volume in the region is bigger, i.e. the porosity in the region is bigger, bigger to the permeability of liquid, So requiring to meet the different of each region, the descending through-hole porosity on the top flat 10 is successively main uptake zone 11, secondary uptake zone 12, comfort zone 13.Preferably, the through-hole porosity of the main uptake zone 11 is the through-hole hole of time uptake zone 12 2 ~ 5 times of gap rate, the through-hole porosity of the secondary uptake zone 12 are 2 ~ 5 times of the through-hole porosity of comfort zone 13.

Since through-hole upper end aperture is bigger, the speed of osmotic absorption liquid is faster, and permeability is bigger, so in order to full The different of each region of foot require, on the top flat 10 via design in 3 regions at upper end aperture it is descending successively based on inhale Receive area 11, secondary uptake zone 12, comfort zone 13.

Through-hole on the top flat 10 is preferably arranged to " V " shape, i.e., the upper end aperture of the described through-hole is greater than the lower stomidium Diameter.When body fluid is discharged on the top flat 10, because the upper end aperture towards skin surface is larger, speed of the body fluid pervious into top flat 10 Relatively fast, and because the lower end aperture towards absorber 20 is smaller, the body fluid for entering top flat 10 is not easy reverse osmosis and returns back to top piece 10 surfaces.

When the material of the top flat 10 is PE making hole film, by the different zones in the top flat 10 using different punchings Form meets the needs of i.e. dry and comfortable absorbent article 100 and soft comfortable.In three regions, the main uptake zone 11 is direct It is directly contacted with the body fluid outlet of human body, which needs the ability of rapid osmotic liquid, so the main uptake zone 11 is adopted Meets the needs of region rapid osmotic liquid with maximum porosity and the punching form in maximum upper end aperture；Described time Uptake zone 12 is to the unabsorbed body fluid in main uptake zone 11 further osmotic absorption, the body fluid of the relatively main uptake zone 11 of body fluid volume Measure it is less, so the secondary uptake zone 12 using the relatively small punching form of porosity and upper end aperture than main uptake zone 11 come Meets the needs of further permeation liquid in the region；The comfort zone 13 requires smoothly, the permeable body fluid of low friction sense Material, so the region meets low amounts using punching form more relatively small than the porosity of secondary uptake zone 12 and upper end aperture The transparent liquid performance of liquid, and the region is because of local eminence around hole caused by punching, so that the area phase of region contact skin To reduction, the phenomenon that chafing against skin is also just opposite to be reduced, and meets the needs of comfort level.In addition, the through-hole on the top flat 10 is set Be set to " V " shape, can reduce enter absorber 20 body fluid return again infiltration return back to top 10 surface of piece the phenomenon that generation, further make The absorbent article reaches dry and comfortable and comfortable effect.

Second of material: the material of the top flat 10 selects non-woven fabrics.

Bigger to the transient absorption power and liquid storage amount of body fluid since fiber is thicker, Test Liquid Permeability of Core is bigger, otherwise fine Tie up it is thinner, performance it is more soft, so the difference of 3 regions of the top flat 10 according to demand is designed to different fibres Rugosity is tieed up, i.e., the fibre coarseness of the described main uptake zone 11 is maximum, and followed by secondary uptake zone 12, the smallest fibre coarseness is comfort zone 13。

Since fibrous layer is thicker, the body fluid and liquid storage amount of absorption are bigger, and fibrous layer is thinner, show slimmer and more graceful easypro It is suitable, so the difference of 3 regions of the top flat 10 according to demand to be designed to different fiber thickness, i.e., the described main absorption The fiber thickness in area 11 is maximum, and followed by secondary uptake zone 12 is most thin for comfort zone 13.

Since fibre density is looser, 20 liquid of fiber absorber is more smooth, and the speed of the infiltration of body fluid is faster, fiber Density is closer, shows more smooth, has relatively low abrasive feel, so by 3 regions of the top flat 10 according to need The difference asked is designed to different fibre densities, i.e., the fibre density of the described comfort zone 13 is maximum, followed by secondary uptake zone 12, It is finally main uptake zone 11.

It is thick using different fibers by the different zones in the top flat 10 when the material of the top flat 10 is non-woven fabrics Degree, fiber layer thickness and fibre density meet the needs of i.e. dry and comfortable absorbent article 100 and soft comfortable.When the top flat 10 Three regions when using the material of different fibre coarsenesses, the most thick main uptake zone 11 of fiber have most fast body fluid absorption power and Maximum liquid storage amount meets maximum body fluid real permeability needed for the zone material；The material that comfort zone 13 selects fiber most thin Matter, embodiment is most soft sense of touch, the requirement of pro-skin softness needed for meeting the zone material；The fibre coarseness of secondary uptake zone 12 Selection meets the requirement of the further osmotic absorption body fluid in the region between main uptake zone 11 and comfort zone 13.

When three regions of the top flat 10 use the material of different fiber layer thicknesses, the most thick main uptake zone of fibrous layer 11 have maximum liquid storage amount, meet the requirement of the maximum permeability of region needs；Comfort zone 13 is most thin using fibrous layer Material, the region is most slim and graceful comfortable, meets the region pro-skin and comfortably requires；Secondary uptake zone 12 fiber layer thickness selection between Between main uptake zone 11 and comfort zone 13, meet the requirement of the further osmotic absorption body fluid in the region.Further, if each Punching design is done in region, then the through-hole that the last main uptake zone 11 of fibrous layer is formed is most deep, and the body fluid through absorbing most is not easy to return infiltration, The minimum for meeting region needs returns the requirement of infiltration rate.

When three regions of the top flat 10 use the material of different fibre densities, the most loose main absorption of fibre density The absorption body fluid of area 11 is most smooth, and body fluid pervious is fastest, and permeability is maximum；The most close comfort zone 13 of fibre density is because of its fibre Dimension interweaves most close and shows that the region surface is most smooth, and minimum abrasive feel, pro-skin needed for meeting the region is comfortably wanted It asks；The fibre density of secondary uptake zone 12 meets the further osmotic absorption in the region between main uptake zone 11 and comfort zone 13 The requirement of body fluid.

Certainly, the non-woven fabrics of above-mentioned three kinds of unlike materials can be together with each other, and be allowed to more meet each region Difference requires.I.e. in three regions, the main use of uptake zone 11 fibrous layer is most thick, fibre coarseness is most thick and fibre density Most loose non-woven fabrics can have highest permeability, meet the performance that the main uptake zone 11 needs rapid osmotic liquid； The comfort zone 13 most thin and most fine and close fibre density non-woven fabrics of most thin, fibre coarseness using fibrous layer, can satisfy this Smooth, the requirement of the liquid permeable of low friction sense that comfort zone 13 needs；The fiber layer thickness of the use of secondary uptake zone 12, Fibre coarseness and fibre density are between main uptake zone 11 and comfort zone 13, to meet the further infiltration of time uptake zone 12 Absorb the demand of body fluid.

It should be understood that can do punching on non-woven fabrics in order to improve non-woven fabrics material to the infiltration rate of liquid and set Meter.Since non-woven fabrics material is easy reverse osmosis liquid, and there is the body fluid of the non-woven fabrics of punching design to return infiltration rate and set greater than no punching Meter non-woven fabrics returns infiltration rate, so to the infiltration rate of liquid and returning infiltration rate for balance non-woven fabrics, it is preferred that enterprising in non-woven fabrics The punching of row low porosity designs.

It should be understood that in order to allow consumer to be easy to pick out the top from the transparent liquid face of the top flat 10 of absorbent article 100 The present position of different zones on piece 10, main uptake zone 11, the secondary uptake zone that can will include on the top flat 10 of the absorbent article 100 12 and comfort zone 13 be arranged to different colours to distinguish.

Absorbent article provided by the present invention, its main feature is that being wanted according to user to the use of the different zones of absorbent article It asks, the top flat 10 is marked off into main uptake zone 11, secondary uptake zone 12 and comfort zone 13, and want for the use of different zones The difference asked makes different designs come 10 material of top flat to absorbent article.Compared with the absorbent article of the prior art, this hair The absorbent article of bright offer can meet not only dry and comfortable but also soft comfortable requirement simultaneously.

In addition, those skilled in the art can also the claims in the present invention scope of disclosure and spirit in do other forms and Various modifications, addition and replacement in details.Certainly, these spirit is done according to the present invention various modifications, addition and replacements It, all should be comprising within scope of the present invention Deng variation.
