Description of the Related Art Japanese Unexamined Patent Publication No. 8-71105 discloses a large-diameter recess formed by partially compressing a topsheet and an absorber, and a large-diameter recess located in the large-diameter recess. There is described an absorbent body for sanitary ware having a small-diameter concave section formed by further denting the topsheet with respect to the large-diameter concave section and being fused to the absorbent body. This absorber has a two-stage nested structure in which the concave portion has a two-stage structure, in which when the concave portion is formed by fusing the surface sheet and the absorbent member, the liquid permeability caused by the surface sheet being formed into a molten film is reduced. It is intended to prevent a decrease in liquid permeability by fusing the topsheet and the absorber only in the deep concave portion. However, in this absorber, when the area of the large-diameter concave portion is large, a large step occurs between a portion where the large-diameter concave portion exists and a portion where the large-diameter concave portion does not exist during wearing, and the feel is greatly different, and the touch is reduced. Would. In addition, the large-diameter concave portion becomes a depressed space, and there is nothing obstructing the flow of the liquid in the space, so if the discharged liquid has a strong momentum, the liquid easily flows along the wearer's skin. However, only a part of the liquid is taken into the large-diameter concave portion, and the entire space cannot be effectively used for liquid absorption.

Sanitary napkins are described. However, in this napkin, since the compressed grooves are formed continuously in a linear manner, deformation inhibition occurs such that the napkin is not easily bent in a direction orthogonal to the direction in which the compressed grooves extend. As a result, it is not easy to fit the napkin to the wearer's body.

トの表面を伝って流れ易くなり、液漏れが起こり易い。JP-A-64-45801 describes an absorbent pad in which a tuft area and a channel for guiding liquid are formed on the entire surface. The channel includes a storage area and a transport area, the storage area having a density greater than the density of the tuft area but less than the density of the transport area. The transport areas are separated from each other by storage areas. However, this absorbent pad is intended to diffuse the liquid widely by the surface uneven structure of the pad,
When a surface sheet is used by being superposed on the pad, the surface sheet does not have an uneven structure along the surface uneven structure of the pad. Therefore, the excreted liquid easily flows along the surface of the topsheet, and liquid leakage easily occurs.

よっても液の吸収が促進される。By having such a concave portion 5 and a convex portion 6,
In the napkin 1, even if the excreted liquid flows along the surface of the topsheet 2, it flows into the concave portion 5 and is quickly absorbed through the side walls of the concave portion 5 and the convex portion 6. Also, since the recesses 5 are formed intermittently and independently,
Compared to a conventional napkin having a linear compression groove, it is easily bent (deformable) in any direction and fits perfectly to the wearer's body shape. By these actions, the surface liquid flow and the liquid leakage resulting therefrom are effectively prevented. Further, since the convex portion 5 is formed in the concave portion 6, the convex portion 5 is not formed (for example, compared with the case where the large-diameter concave portion described in JP-A-8-71105 is formed). Thus, the difference in feel between the portion where the concave portion 6 is formed and the portion where the concave portion 6 is not formed is less likely to be noticed, and the sense of discomfort during mounting is eliminated. In particular, since the concave portion 5 is unevenly distributed on both the left and right sides of the napkin 1 where the wearer's skin is most likely to hit, if the convex portion 6 is not present, it is easy to feel the sense of incongruity of the step caused by the concave portion 5, Since the convex portion 6 is formed in the concave portion 5, there is no danger.
In addition, the liquid flowing into the concave portion 5
Since the liquid is dispersed by the convex portions 6 formed therein, the absorption of the liquid is also promoted.

It is arranged to be. Thereby, when the excreted liquid flows in the width direction of the napkin 1, it always flows into any of the concave portions 5, and the liquid flow path is dispersed, so that lateral leakage is effectively prevented. In this embodiment, since the concave portions 5 are arranged in a staggered pattern as shown in FIG. 1, the liquid flowing in the width direction of the napkin always flows into any of the concave portions 5. The distance between adjacent recesses 5 in the longitudinal direction of the napkin 1 (the length connecting the centers of the recesses 5) depends on the size of the recesses, but is 5 to 30 m.

In other words, the top 6a of the projection 6 does not protrude significantly above the surface B passing through the peripheral edge 5a of the recess 5 (this surface is flush with the skin contact surface of the napkin 1). preferable. Convex part 6
If the protrusions protrude more than the surface B, the convex portions 6 are likely to hit the wearer's skin, which tends to cause a feeling of strangeness. When the height of the convex portion 6 is smaller than the depth of the concave portion 5, the height of the convex portion 6 is so high that the convex portion 6 can come into contact with the wearer's skin when the napkin 1 is mounted. . Although it depends on the thickness of the absorber 4 and the sizes of the convex portions 6 and the concave portions 5,
The height of the protrusion 6 is preferably 0.5 to 1.2 times, particularly preferably 0.7 to 1 times the depth of the recess 5. Thereby, when the napkin 1 is mounted, a part of the convex portion 6 comes into effective contact with the skin, and the occurrence of a step due to the formation of the concave portion 5 is less likely to be noticed. The feeling of discomfort is further reduced. Moreover, as described above, since the convex section 6 has a curved vertical cross-section, it does not give any discomfort when it comes into contact with the skin.

７を配することで、後ろ漏れが完全に防止される。The recesses 5 and 7 are arranged such that, when attention is paid to a region between the recesses 5 and 7 adjacent to each other in the width direction of the napkin, the recess is located at any position before or after the region. As a result, when the excreted liquid flows toward the rear end of the napkin, it always flows into one of the recesses 5 and 7, and the flow path of the liquid is dispersed, so that the back leakage is effectively prevented. . In this case, of the concave portions 5 and 7, the small-diameter concave portion 5 is disposed relatively closer to the center of the napkin 1 and the large-diameter concave portion 7 is disposed relatively closer to the end of the napkin 1. The bending stiffness value of 1 is in a more appropriate range, and the followability to the movement of the body is improved. Further, of the concave portions 5 and 7, the concave portion 5 having one convex portion 6 is
By disposing the concave portion 7 having a plurality of convex portions 6 relatively toward the end portion of the napkin 1 relatively closer to the center portion, the portion more easily comes into contact with the skin than the central portion. The step of the concave portion at a position near an end is further reduced,
The feel is good. In particular, in the present embodiment, the small-diameter concave portion 5 is disposed relatively to the central portion of the napkin 1, and the excreted liquid always flows into the large-diameter concave portion 7 when the excreted liquid flows toward the rear end of the napkin. By arranging the large-diameter concave portion 7 so as to flow in, rear leakage is completely prevented.
