Description of the Invention: [Technical Field] The present invention relates to a thin layer suitable for use in sanitary articles, and more particularly to a thin layer which can control the flow of a liquid and a sanitary article having the same. [Prior Art] Generally, sanitary products such as sanitary napkins, diapers or medical pads, in order to prevent leakage of absorbed liquid, are usually provided with a leak-proof liquid and a liquid leakage prevention function. In the layer, the leakage preventing layer is usually made of a perforated film made of polyethylene, and the leakage preventing layer is in contact with the skin of the user to provide a feeling of dryness and comfort for the user. As shown in FIG. 1 , a top surface of a generally perforated film crucible is formed with a plurality of generally rhombic ribs 11 , and a plurality of hydrophobic holes 13 are formed in the flow guiding region 12 defined by each rib rib. The pore diameter of the hydrophobic pores 3 adjacent to the top surface of the perforated membrane is larger than the pore diameter of the bottom surface adjacent to the perforated membrane 1. In actual use, the top surface of the perforated film 1 is for contacting the skin of the user's body, and the absorbent cotton body (not shown) is disposed at the bottom surface of the perforated film 1, and when the liquid passes through the perforated film 1, Each of the ribs 11 breaks the surface tension of the liquid, reducing the probability of the liquid sticking to the top surface of the perforated film 1 to improve the dry comfort between the perforated film 1 and the user's skin. In addition, the perforated film 1 is in direct contact with the user's skin by the rib U, which can reduce the contact surface area between the perforated film 1 and the user's skin, so as to reduce the long-term contact or friction between the perforated film 1 and the user's skin. Produces a sultry or allergic phenomenon. However, when the cohesive force of the liquid is too large, the effect of the surface tension of the liquid 5 1337859 by the rib U alone is not good, so how to conceive a perforated film which has a good effect of destroying the surface tension of the liquid to improve the liquid permeation effect, The subject matter of the invention to be further improved. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a thin layer of a controllable liquid which is capable of effectively destroying the surface tension of a liquid to enhance the liquid permeation effect and capable of rapidly diverting the liquid. Another object of the present invention is to provide a sanitary article having the thin layer capable of rapidly diverting a liquid to keep the surface dry and comfortable to use. Thus, the present invention can control the flow of the liquid to the thin layer, comprising: a substrate having a first surface and a second surface opposite to the first surface; and a plurality of ribs bulging from the first surface of the substrate Arranging adjacent to each other, the ribs define a plurality of flow guiding regions; a plurality of perforations are disposed on the flow guiding regions and penetrate the first surface and the second surface; and a plurality of recessed regions And disposed on the ribs such that the flow guiding regions can communicate with each other by the recessed regions. Furthermore, the sanitary article of the present invention having the thin layer comprises: an absorbent body for absorbing a liquid; and a thin layer covering the absorbent body, the thin layer comprising: a substrate having a a first surface, a first surface opposite to the first surface; 6 1337859. A plurality of ribs are embossed from the first surface of the substrate and adjacent to each other 'the ribs and define a plurality of diversions a plurality of perforations disposed on the flow guiding regions and extending through the first surface and the second surface; and a plurality of recessed regions disposed on the ribs such that the flow guiding regions can The recessed areas are connected to each other. The effect achieved by the invention is that the surface tension of the liquid can be effectively destroyed to enhance the liquid permeation effect, and the liquid can be quickly guided to the adjacent diversion region through the recessed regions, and outputted by the perforations on each of the diversion regions. So that the surface of the thin layer can be kept dry. [Embodiment] The above and other technical contents 'features and effects of the present invention' will be clearly described in the following detailed description of a preferred embodiment of the accompanying drawings. Referring to Figure 2, the thin layer 3 of the present invention for controlling the flow of liquid comprises a substrate 31. In this example, the substrate 31 is a perforated film made of a polyethylene (pE) material. Of course, the substrate 31 can also be Polypropylene (pp) or composite or non-woven fabric. As still shown in Figures 2 and 3, the base 31 has a first surface 311 and a second surface 312 opposite the first surface 311, the first surface 311 having a plurality of ribs 313 arranged adjacent to each other. The ribs 313 define a plurality of polygonal shaped flow guiding regions 314, and a plurality of perforations 315 are disposed on each of the guiding regions 314. In addition, the ribs 313 are provided with a plurality of recessed regions 316, and the recessed regions 316 are located on the same plane 316 as the first surface 7 1337859 3U of the base 31 and communicate with each other.

As shown in Fig. 4, in practical application, the thin layer 3 will cooperate with the absorbent body 4 to form a sanitary article such as a sanitary napkin or a diaper, and the absorbent body 4 is disposed on the bottom surface of the base 31 due to the ribs. Each of the 313 is raised from the first surface 3 of the base body, so the first surface 311 of the rib 313 and the base 31 are at different heights of the plane, and the ribs 313 are formed with the base 31. The first surface 311 is located in the same-plane recessed area 316, so that when the sanitary article is used, the thin layer 3 is in contact with the user's skin 5 by the ribs 313, thereby reducing the thin layer 3 and the use thereof. The area in contact with the skin 5 reduces the phenomenon that the thin layer 3 is in contact with or rubbed against the user's skin 5 for a long time, causing the user's skin 5 to become stuffy or allergic. On the other hand, the arrangement of the ribs 313 and the recessed portions 316 can also make the thin layer 3 more detailed in overall tactile sensation, thereby increasing the user's comfort in use. In addition, as shown in FIG. 5, since the flow guiding regions 314 can communicate with each other by the recessed regions 316, the liquid can be discharged through the perforations 315 on the flow guiding region 314 except that the liquid can be broken by the convex ribs 313. The absorbent body 4 under the thin layer 3 is rapidly absorbed. At the same time, the liquid can be discharged through the depressed portions 316 and then quickly guided to the different flow guiding regions 314, and 8 1337859 is also absorbed by the absorbent crucible 4. In particular, although the thin layer 3 of the present embodiment is exemplified by having a single layer of ribs, the number of the rib layers may be increased or decreased depending on the requirements of the conventional knowledge. The limits disclosed are limited. In addition, the depressions gig disposed on the ribs 313 of the present invention may also have different depths of depressions. As shown in FIG. 6, the depressions of the depressions 1 316 are smaller than the ribs 313. The height is small; as shown in FIG. 7, the depression of the depressions 316 can also be greater than the height of the ribs 313, so that the ventilation is also provided when contacting or rubbing against the user's skin 5. Good sex and comfortable touch. As described above, the present invention can be quickly guided to the different flow guiding regions 314 by the recessed portion 316 by the upper structural design, and can be quickly applied to the different guiding regions 314 by the recessed portion 316, and is quickly formed by the perforations 315. Discharged and absorbed by the absorbent body 4, so that the surface of the thin layer 3 can be surely maintained in a dry state, and the ribs 313 and the recessed portion 316 are disposed in such a manner that the thin layer 3 and the user's skin 5 can be The contact area is reduced, the ventilation effect is better, and the user's comfort in use is increased. However, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention, All should remain within the scope of the invention patent.
