By adhering only the inner edge of the folded portion to the surface of the water-permeable top sheet, a substantially hollow portion with openings at opposite ends in the longitudinal direction is formed.
（実施例）
本考案を図示の実施例に基づいて説明すると、
以下のとおりである。(Example) The present invention will be explained based on the illustrated example.
It is as follows.
第１図、第２図において、ナプキン１は、公知

フラツプ５，６とを含む。 In FIGS. 1 and 2, the napkin 1 includes a water-permeable top sheet 2, a water-impermeable back sheet 3, and cotton-like pulp interposed between the front and back sheets 2 and 3, as in the known napkin. The absorbent body 4 includes an absorbent body 4, and flaps 5, 6 formed at opposite ends and opposite sides of the front and back sheets 2, 3 extending outward from the outer peripheral edge of the absorbent body 4 and joined to each other.

接着することにより、縦方向対向端が開口する実
質的に中空状部分８を形成してある。 Furthermore, the napkin 1 is provided with arcuate cuts 7 at intervals in the vertical direction, biased toward one end of the flap 6 on the opposite side, and a portion 6a between the longitudinally opposing cuts 7 is folded back toward the skin contact surface. be. The inner edge 6b of the folded portion 6a is adhered to the side edge of the region where the absorbent body 4 is located by heat welding, adhesive, or the like. By bonding only the inner edges of the folded back in this manner, a substantially hollow portion 8 with an open longitudinally opposite end is formed.
第３図に示す実施例においては、折り返し部分
６ａの内側縁６ｂをフラツプの領域に接着するこ

状部分８を形成してある。 In the embodiment shown in FIG. 3, the inner edge 6b of the folded portion 6a is glued to the area of the flap, thereby forming a substantially hollow portion 8 which is open at opposite longitudinal ends.

空状」の意味に含まれる。 Here, "substantially hollow" means that a space may be formed between the folded portion 6a of the flap 6 and the portion located on the lower surface of the flap 6, through which air can flow in and out from the open end, regardless of the shape or size of the cross section. It means that the condition is good. Therefore, in some cases, even if the hollow part 8 is compressed, if air can flow in and out due to the wearer's exercise when wearing it, then this is also considered to be "substantially hollow". ” included in the meaning.

には充分に理解されよう。 The hollow portion 8 is provided to provide elasticity (cushionability), but in order to further improve the elasticity, the back sheet 3 is preferably a foamed sheet such as polyurethane or polyethylene having soft elasticity. Those made by heating and pressurizing them to force out the air bubbles may be used.
Note that these materials are not shown in the drawings, but will be well understood by those skilled in the art.
フラツプ６、中空状部分８の機能を充分に発揮

ろんである。(Operations and Effects of the Invention) As described above, the present invention has flaps formed at least on the opposing outer sides, and also folds back a portion of the flaps on both sides to form a narrow central region of the napkin. Of course, it has the general effect of fitting closely to the groin area of the user.

として実用に供しきわめて有益である。 Furthermore, in the present invention, since only the inner edge 6b of the folded portion of the flap is adhered to the skin surface, a substantially hollow portion is formed there. Therefore, the hollow part comes into elastic pressure contact with the inner side of the wearer's crotch and thigh, which not only alleviates the feeling of use and discomfort that the wearer feels from the napkin, but also reduces the wearer's groin area. In response to movement, the elasticity (cushionability) allows it to freely deform by shrinking, being compressed, or restoring itself, while maintaining good contact with the skin. Moreover, even when subjected to various effects due to the movement of the wearer's groin area, wrinkles, folds, twists, etc. that can lead to leakage of menstrual blood are unlikely to occur, and even if they occur,
It is not maintained in a fixed manner; in other words, the function of the hollow portion restores the state of good contact with the skin. Furthermore, the free deformation and restoring of the hollow portion can be said to perform a kind of pump function, which prevents stuffiness that occurs when the napkin is worn for a relatively long period of time or when worn in hot weather. Another advantage is that it can be prevented. Therefore, it is extremely useful for practical use as a napkin, especially when you are at work and cannot change your napkin for a relatively long time, or when you wear it at night.
