No. 4,440,34 has been proposed. In the technique described in Japanese Utility Model Laid-Open Publication No. 58-13225, a slit is provided at the center in the width direction of the rear part of the absorbent body of the absorbent article, the slit reaching the rear edge of the absorbent body. In addition, in the technique described in Japanese Utility Model Publication No. 63-44034, when the absorbent article is worn, the absorptive article is placed from one point at the center in the width direction on the rear skin contacting surface side arranged behind the wearer. A three-dimensional groove extending in the longitudinal direction of the article and a three-dimensional groove extending from the above one point to the left and right side edges and extending to the rear edge are provided.

Further, since the three-dimensional groove or slit is formed so as to reach the edge of the rear part, there is a possibility that bodily fluid may easily leak from the edge of the rear part along the three-dimensional groove or slit. Further, in the technology described in Japanese Utility Model Application Laid-Open No. 58-13225, the slit is provided only in the absorber, so that the topsheet floats up from the absorber and the body fluid is not absorbed by the absorber and passes over the topsheet. There is a risk of leaking along.

物品が提供できる。More specifically, in the sanitary napkin 1 according to the present embodiment, the three-dimensional groove 50 is formed symmetrically in the left and right direction, and has a convex shape protruding forward at the central portion 1c in the longitudinal direction. Shape part. In addition, the three-dimensional groove 50 is formed in a bow shape curved inward in the width direction of the sanitary napkin 1 at the rear of the convex portion, and is greatly curved as approaching the end edge 1d. As it approaches the edge, it is arranged away from the edge 1d and the edge 1e while approaching the side edge of the rear part. The convex portion is preferably a radius of curvature r 1 is formed so as to be 5 to 20 mm. Radius of curvature r 1 is 5
If it is less than mm, the inside of the convex portion is not sufficiently raised to fit the buttocks, which is not preferable. If it is more than 20 mm, the width of the raised portion is too wide to fit the buttocks, which is not preferable. In this way, from the longitudinal central portion of the absorbent article to the rear portion arranged behind the wearer at the time of wearing,
By forming the three-dimensional groove 50 having a convex part convex toward the front in the longitudinal center part 1c, the rear part is deformed using the three-dimensional groove 50 as a flexible axis at the time of mounting, and the inside of the three-dimensional groove is formed. Since it is raised and fits more closely to the shape of the buttocks, menstrual blood flowing on the surface is blocked and quickly absorbed without passing through the body, so that it is possible to provide an absorbent article that is less likely to leak backward.

The distance L 2 between 50b and the edge 1d of the sanitary napkin 1 is 1
0 to 50 mm, the rear end 50b of the three-dimensional groove 50,
The distance L3 between 50b and the side edges 1e, 1e is 5 to 30 mm. Solid grooves 50, in addition to functioning as a flexible shaft to facilitate uplift and deformation of the absorbent article, also serves to block the menstrual blood flowing through the surface, L 2 is less than 10 mm, L
If 3 is less than 5 mm, menstrual blood flowing out of the groove may leak to the outside of the absorbent article as it is, which is not preferable.
Further, the three-dimensional groove 50 has a smaller radius of curvature near the rear ends 50b and 50b than immediately behind the convex portion.
That is, in the vicinity of the rear ends 50b, 50b, the side edges 1e,
In order to incline toward the 1e side, for example, the radius of curvature immediately behind the convex portion is 100 mm or more, and the rear ends 50b, 5
It is preferable that the radius of curvature in the vicinity of 0b is curved to be 30 to 100 mm. By forming the three-dimensional groove 50 having such a curvature in such a position, a more ideal mounting form can be taken, and the rear part of the sanitary napkin 1 can be fitted to the buttocks more widely. .

Central grooves 60, 60 are formed symmetrically in two in the abutment part, and the front part 1 of the sanitary napkin 1 is formed.
a and the central portion 1c always form an arched cross-section at the time of mounting, so that the crotch can be fitted well.

If the depth D of 0,60 is less than 1 mm, it is difficult to obtain flexibility in the groove portion, and a favorable fit cannot be obtained,
The effect of blocking the bodily fluid flowing on the surface is difficult to obtain, which is not preferable. If it exceeds 10 mm, the wearer will feel uncomfortable and will not be preferable. Further, the thickness T 1 of the sanitary napkin 1 at the portion where the three-dimensional groove 50 and the central grooves 60 and 60 are formed.
Is preferably 0.05 to 0.7, and the ratio T 1 / T 2 to the thickness T 2 in the portion where the groove is not formed is preferably 0.05 to 0.7.

If the thickness of the absorbent sheet 30 is less than 0.3 mm, the rigidity of the sheet itself is too small to form and maintain a preferable arch form between the central grooves 60, and if it exceeds 5 mm, The seat stiffness becomes too high or the thickness of the sanitary napkin 1 becomes too thick, so that a feeling of strangeness at the time of wearing is increased. When the thermoplastic fibers are bonded to each other in the absorbent sheet 30, the thermoplastic fibers keep the shape of the absorbent sheet 30 stable when absorbing body fluid, so that the preferable mounting form of the sanitary napkin 1 is improved. It is preferable to maintain the sanitary napkin 1 when the pressure is released, to restore the original state, and to keep the sanitary napkin 1 stable without twisting.

However, in order to fit the crotch more and take an ideal form, It is preferable that the central portion in the longitudinal direction is curved toward the center in the width direction and has a bow shape. The distance between the portions of the two three-dimensional grooves that are closest to each other is 10 to 40 mm.
It is preferred that If the distance of the closest part is less than 10 mm, the space between the three-dimensional grooves 50 ′ and 50 ′ is not sufficiently raised and does not fit the buttocks, which is not preferable.
If it exceeds mm, the width of the raised portion is too wide and it is difficult to fit the buttocks, which is not preferable. In addition, the three-dimensional groove is not limited to the one continuous from the front end to the rear end as in the above-described embodiment.

Further, when formed by a plurality of discontinuous small grooves divided in the longitudinal direction as in the above-described embodiment, the shape of the small grooves is not particularly limited. Further, the three-dimensional groove can be formed by machining a groove from the non-skin contact surface side. However, in order to easily protrude between the three-dimensional grooves and obtain good fit, a groove from the skin contact surface 2 side is required. It is preferably formed by processing.
