Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Embodiment 1
Present embodiments provide a kind of disposable sanitary articles, as shown in Figure 1, this disposable sanitary articles comprises permeable top layer 1, opaque liquid bottom 2, and absorption between permeable top layer 1 and opaque liquid bottom 2 absorbed layer 3 of receiving fluids; Described permeable top layer 1 is provided with netted liquid-tight layer 4 away from the side of absorbed layer 3, and described netted liquid-tight layer 4 is evenly distributed with some liquid drain hole 41; Liquid can infiltrate in absorbed layer 3 from liquid drain hole 41, and the region of the non-liquid drain hole 41 of netted liquid-tight layer 4 is made up of water-proof material, and liquid is difficult to remain in surface, can ensure the dry-ness of surface.
In the present embodiment, the diameter of described liquid drain hole 41 is 2mm-10mm, and preferably, the diameter of described liquid drain hole 41 is 2mm-3mm, being convenient to liquid infiltrates in absorbed layer 3 from liquid drain hole 41, and the diameter of liquid drain hole 41 is crossed senior general and can not be ensured the dry-ness of product surface; Liquid drain hole 41 diameter is crossed young pathbreaker and is unfavorable for that liquid infiltrates in absorbed layer 3.The percent opening of described netted liquid-tight layer 4 is 20%-80%, in the present embodiment, preferably, the percent opening of described netted liquid-tight layer 4 is 40%-60%, be convenient to liquid infiltration and enter absorbed layer 3, ensure that the dry-ness of product surface by the region of the non-liquid drain hole 41 of netted liquid-tight layer 4 simultaneously.
In the present embodiment, the shape of described liquid drain hole 41 is regular geometric figure, and preferably, the shape of described liquid drain hole 41 is circular, oval or any one in rhombus, adopts regular collection figure to facilitate the processing of liquid drain hole 41 greatly, reduces production cost.
Embodiment 2
The difference of the present embodiment and embodiment 1 is, as shown in Figure 2, described absorbed layer 3 comprises the first absorbed layer 31, second absorbed layer 32 and the 3rd absorbed layer 33 of the close permeable top layer 1 set gradually; All the other structures are identical with embodiment 1, do not repeat them here.
Described first absorbed layer 31 and the second absorbed layer 32 are respectively equipped with pod apertures 311 and lock fluid apertures 321, and non-pod apertures 311 region of liquid in pod apertures 311 and the first absorbed layer 31 enters the second absorbed layer 32, then enters the 3rd absorbed layer 33.Wherein, described pod apertures 311 is bellmouth, and less near the bellmouth aperture of permeable top layer 1; Described lock fluid apertures 321 is bellmouth, and less near the bellmouth aperture of liquid-tight bottom 2.Be convenient to liquid by pod apertures 311 and enter the second absorbed layer 32, liquid can be made to be locked in absorbed layer 3 by pod apertures 311 and lock fluid apertures 321 simultaneously, prevent liquid from oozing out, ensure that the dry-ness of product surface, improve the comfort level of contact skin, prevent the moisture content of product surface too high and cause the untoward reaction such as flushing, eczema.
Described pod apertures 311 and the lock interlaced distribution of fluid apertures 321 and be interconnected, namely the under shed of pod apertures 311 has part relative with the upper shed of lock fluid apertures 321 but not completely relatively, realize pod apertures 311 to be communicated with lock fluid apertures 321 part, so that liquid enters the second absorbed layer 32, prevent simultaneously lock fluid apertures 321 and pod apertures 311 connected region excessive, so that be wherein lockable too much liquid, cause liquid to ooze out along lock fluid apertures 321, reduce the dry-ness of product surface.
Obviously, the above embodiment of the present invention is only used to clearly demonstrate example of the present invention, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All any amendments done within the spirit and principles in the present invention, equivalent to replace and improvement etc., within the protection domain that all should be included in the claims in the present invention.
