BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings. The present invention is a sanitary napkin for use outside the body formed with a pad layer 1 of a water-absorbent resin. It is preferable that the pad layer 1 of the water-absorbent resin is formed by laminating the water-absorbent resins having different fibrous, permeable and water-retaining properties.

Both sides 4 in the longitudinal direction of the front half 3 corresponding to the crotch portion 2 of the body are folded back in the order of inside and outside. The both side portions 4 are gradually narrowed toward the rear half portion 6 corresponding to the buttocks 5.

In this embodiment, not only the side portions 4 but also the front end portion 7 of the front half portion 3 are folded back in the order of inside and outside, and the front end portion 7 and the side portions 4 continuous with the front end portion 3 are surrounded on three sides. The pad layer 1 has a front end portion 7 folded back in and out.
And the upper exposed surface 8 of both side portions 4 are formed.
In the case of the present invention, the front half portion 3 may be formed by folding back only both side portions 4 as shown in FIG. 5, for example. In this case, the pad layer 1 is formed only on the upper exposed surface 8 of both side portions 4.

A rear half portion 6 corresponding to the buttocks 5 is formed integrally with the front half portion 3 in a continuous manner and widens toward the rear end 9. In addition, the napkin of the present invention is preferably formed thinner toward the rear end 9 so that it fits the buttocks 5 and is comfortable to use and wear. The rear end 9
Is formed in a linear shape in this embodiment, but is not limited to this and may be, for example, a curved shape.

Further, in the present invention, it is preferable that the rear half 6 is formed on the side of the front half 3 so as to facilitate the mounting. In this embodiment, the gathers 4a are provided on both side portions 4 described above.
Are formed so that the upper surfaces of both side portions 4 are contracted by the gathers 4a, and the rear half portion 6 is raised toward the front half portion 3 side.

Next, an example of use of the present invention will be described. According to the present invention, as shown in FIG.
Then, the rear half 6 is applied to the buttocks 5 and is attached to the outside of the body for use. According to the present invention, as described above, since both side portions 4 of the front half portion 3 are folded back inward and outward, the front half portion 3 is shaped like a concave step or a scooping shape by the both side portions 4. Therefore, the first half 3 has high water retention and water absorption, is absorbed even when there is a lot of bleeding during menstruation, and does not leak sideways.

Further, in the case of the present invention, the rear half portion 6 is formed so as to widen toward the rear end 9. Therefore, in the present invention, since the pad layer 1 of the water-absorbent resin is also formed so as to be widened toward the rear end 9, the formation area of the pad layer 1 is increased, and the portion that cannot be completely absorbed in the first half portion 2 is the latter half portion. Absorbed by 6.

[0017]

As described above, according to the present invention, since both sides in the longitudinal direction of the front half corresponding to the crotch part of the body are folded back in the order of inside and outside, the front half is laterally folded at both sides. Is closed and shaped like a concave step. Therefore, according to this, even when there is a large amount of menstrual bleeding due to a female disease such as uterine fibroids, it can be absorbed in the first half and side leakage can be prevented. Further, according to the present invention, the rear half portion corresponding to the buttocks is formed so as to widen toward the rear end. Therefore, in the case of the present invention, the pad layer of the water-absorbent resin can be formed in the second half portion in a wide range over a wide range, so that water absorption and water retention can be improved.

In the second aspect of the invention, the front half part is surrounded on three sides by the folded back front end part and both side parts continuous with the front end part. Therefore, according to this, the water absorption and water retention of the first half can be further improved.

When the present invention is formed so that it becomes thinner toward the rear end as described in claim 3, for example, it is possible to eliminate the discomfort when sitting, eliminate the fear that the thickness is visible, and the buttocks. It can improve the fit, usability and wearing feeling.

When the rear half portion is formed by being bent toward the front half portion as described in claim 4, the shape fits the line of the body, which facilitates the wearing. There is an advantage that the usability is improved.

Further, according to the present invention, since the pad layer of the water absorbent resin is formed over the front end portion folded back inward and outward and the upper exposed surface of both sides, if this is used, the pad layer is exposed on the upper exposed surface. Since the pad layer is formed, the feeling of resistance during use and the feeling of wearing can be softened. Further, in this case, since the pad layer is expanded by the amount of the pad layer formed on the upper exposed surface, it is possible to further improve water absorption and water retention.
