The specific embodiment
In conjunction with the accompanying drawings this utility model is described in further detail below by the specific embodiment.
For solving the problem of the easy reverse osmosis of urine that exists in the existing diaper, the utility model proposes a kind of diaper, as Figure 1-3, this kind diaper comprise top layer 1, leakproof bottom 4 and be covered by the top layer and the leakproof bottom between absorbent core layer 3; That is to say that top layer 1, absorbent core layer 3 and leakproof bottom 4 are cascading.This kind diaper also comprises the film 2 that is arranged between top layer 1 and the absorbent core layer 3, and this film 2 is not have imbibition ability.On this film, be provided with the through hole 5 that connects two surfaces.For explaining conveniently, at this, will be defined as the upper surface of film near the surface of the film of top layer one side, so, the surface of the film of close absorbent core layer one side is defined as the lower surface of film.That is to say, on this film 2, be provided with the through hole 5 that connects upper and lower two surfaces.
When urine contacts with film 2, though film 2 does not have imbibition ability, utilize the through hole that connects upper and lower two surfaces on the film 2, under the effect of urine gravity and capillary force, urine can successfully be absorbed sandwich layer 3 and absorb.When the baby wear that the diaper that has absorbed urine is sitting on the ground or other local time, even baby's self gravity is applied on the diaper and pushes diaper, because the film in this kind diaper does not have imbibition ability, so, the urine in the absorbent core layer is not easy reverse osmosis and returns on the top layer.Therefore, the design of this kind diaper can guarantee that diaper can absorb urine smoothly on the one hand, makes again that on the other hand urine is not easy reverse osmosis, thereby has guaranteed the dry and comfortable property of paper diaper surface layer.
The design of through hole has guaranteed that absorbent core layer can successfully absorb urine on the film.Though the urine in the absorbent core layer may be gone back to the top layer by the through hole reverse osmosis on the film, this is small part after all.And, can also the amount of urine of going back to the top layer by the through hole reverse osmosis be reduced as much as possible by reasonably designing the shape of through hole.But the shape of through hole has a variety of, as square hole, and circular hole etc., different aperture shape, it stops the ability of urine reverse osmosis also different.In order to make film stop the reverse osmosis of urine better.In the shape of design through hole, a main principle that needs to hold is: the through-hole aperture size on the surface of close top layer 1 one sides is greater than the through-hole aperture size near the surface of absorbent core layer 3 one sides on the film 2.Specifically, promptly the size of the through-hole aperture of the upper surface of film is greater than the size of lower surface.There are two benefits in like this aperture of design through hole: on the one hand, because the upper surface through-hole aperture of film is bigger, can guarantee that like this urine leaves the top layer fast, absorb thereby be absorbed sandwich layer; On the other hand, when the baby pushed diaper, because the lower surface aperture of film is less, this made the urine of absorbent core layer be difficult to reverse osmosis and goes back to the top layer, has reduced the ratio that the amount of urine reverse osmosis goes back to the top layer, has further guaranteed the dry and comfortable property on top layer.
In fact, the through-hole aperture size of the upper surface of film also has a variety of greater than the mode of the aperture size of lower surface, stepped hole for example, and promptly the side in hole is a cascaded surface.But as shown in Figure 2, in a kind of embodiment of the present utility model, through hole is a funnel-shaped hole.That is to say that to lower surface, the aperture of through hole reduces gradually from the upper surface of film.So design, funnel-shaped hole not only can be stored a large amount of urines from the top layer, make urine can leave the top layer fast, and under the effect of urine gravity and capillary effect, the urine that is stored in the funnel-shaped hole can flow downward fast, can not cause the accumulation of urine, strengthen the absorbent properties of diaper at the film place.Simultaneously, when the baby pushes diaper,, further strengthened the ability of film prevention urine reverse osmosis because the effect of funnel-shaped hole makes the more difficult reverse osmosis of urine of absorbent core layer go back to the top layer.In order further to optimize the ability that diaper stops the urine reverse osmosis, in this kind embodiment, also be that certain requirement is arranged to the size of film, promptly the size of film is greater than the size of absorbent core layer and cover absorbent core layer fully.Design like this, the urine that the prevention as much as possible of film ability may be gone back to the top layer from the absorbent core layer reverse osmosis.If film undersized promptly can not cover absorbent core layer fully, there is not the urine on the absorbent core layer part that tunicle covers to go back to the top layer by reverse osmosis so, afterwards with baby's contact skin, influence baby's skin.
Certainly, owing to have through hole all the time on the film, when baby's self gravity pushes diaper, may still have the small part urine in the absorbent core layer and go back to the top layer by the through hole reverse osmosis.In order further to guarantee the dry and comfortable property on top layer, improve the urine diffusion of diaper, farthest utilize absorbent core layer, in an embodiment of the present invention, between film 2 and absorbent core layer 3, also be provided with one deck water conservancy diversion layer.Film 2, water conservancy diversion layer and absorbent core layer 3 are cascading.The effect of water conservancy diversion layer is: can help effectively that on the one hand the urine on the top layer 1 is transmitted to absorbent core layer 3 fast and by its fast Absorption, thereby make liquid leave baby's skin very soon, make the urine diffusion profile, keep infant skin dry and comfortable.On the other hand, when the baby pushed diaper, even the meeting of the urine in the absorbent core layer 3 reverse osmosis, the water conservancy diversion layer also can absorb the urine of reverse osmosis, and this will reduce the amount of urine of going back to the top layer by the through hole reverse osmosis again, make urine almost not have reverse osmosis to return the possibility on top layer.Utilize the water conservancy diversion layer, stopped the further reverse osmosis of urine, thereby guaranteed the dry and comfortable property on top layer again.The water conservancy diversion layer can be selected to be made by hot blast non-weaving cloth, chemical adhesion non-weaving cloth or air-laid nonwoven fabric, is the best to select hot blast non-weaving cloth water conservancy diversion layer wherein.Similarly, in order to guarantee the dry and comfortable property of paper diaper surface layer, the size of film is greater than arbitrary layer size in absorbent core layer and the water conservancy diversion layer, and covers absorbent core layer and water conservancy diversion layer fully.
