As shown in FIG. 2, left and right three-dimensional guards 7 are provided.
Are each formed from one three-dimensional guard forming sheet 71. That is, the three-dimensional guard 7 adheres the three-dimensional guard forming sheet 71 arranged so as to cover the side edge of the absorber 4 from the side edge on the leg part 6 side of the diaper to the topsheet 2 at the base end part 70, The folded part 7a is formed by folding the three-dimensional guard forming sheet 71 located on the inner side in the width direction of the disposable diaper toward the upper side of the diaper (the surface side of the top sheet 2) and outwardly in the width direction. It consists of. With this configuration, the three-dimensional guard 7 is positioned between the lower wall 74 located between the base end 70 and the bent portion 7a and between the bent portion 7a and the free end 7b. And an upper wall portion 75. And the lower wall 7
Since the upper wall 4 and the upper wall 75 are free parts that are not bonded to other members (such as the top sheet 2 and the back sheet 3), both are integrally and continuously used during use. A leak-proof wall that rises upward is formed. Also, the three-dimensional guard forming sheet 71
Is disposed so as to cover the side surface of the absorber 4 and the side edge of the leg portion 6 of the disposable diaper, and is fixed to the back sheet 3. As a result, the elastic members 61 of the leg 6
Are sandwiched and fixed between the back sheet 3 and the three-dimensional guard forming sheet 71. In the back part B and the abdominal part A, the three-dimensional guard forming sheet 71 is entirely fixed to the top sheet 2 in a folded form, and the three-dimensional guard 7 is not formed. That is, the three-dimensional guard 7 need not be formed over the entire disposable diaper as long as it is formed at least in the crotch part C.

Examples of the three-dimensional guard forming sheet 71 include a water-repellent nonwoven fabric. As such a water-repellent nonwoven fabric, any water-repellent nonwoven fabric which is usually used for absorbent articles such as disposable diapers can be used without any particular limitation.Specifically, using the following forming materials, A nonwoven fabric formed according to the method can be used. Forming materials: Filaments formed from a single thermoplastic resin such as polyethylene, polypropylene, polyethylene terephthalate and polyamide; Water-repellent nonwoven fabric materials such as composite filaments having a core / shell, side-by-side structure, etc. Forming method: spun bond method, binder method, water needling method, needle punch method, etc. Specifically, by ordinary melt spinning, the filament is stretched as required, crimped, and the cut short fibers are heat-bonded with an adhesive or the like, or entangled with a water stream, a needle, or the like, That is, a wet method, a dry method, a spunlace method, a spunbond method, or the like. In addition, as the nonwoven fabric, a nonwoven fabric composed of split filaments obtained by forming a multilayer filament and then dividing the multilayer filament by an external force can be used. Furthermore, a nonwoven fabric directly formed by a melt blown molding method can be used.

The disposable diaper 1 of the present embodiment can be used in the same manner as a normal deployable disposable diaper. The three-dimensional guard 7 in the disposable diaper 1 of the present embodiment includes:
In use, as shown in FIG.
The upper wall 4 and the upper wall 75 rise slightly inclining so that the outer side in the width direction of the disposable diaper 1 faces upward, and rises substantially upright as a whole. In addition, the side flaps also stand upward by the action of the leg gathers. Since the three-dimensional guard is configured as described above, it is possible not only to stop the leakage at the lower wall portion 74 but also to effectively protect the bodily fluid leaking beyond the lower wall portion at the upper wall portion. In addition, the conventional simple inward three-dimensional guard may cause absorption inhibition of the absorber, but the disposable diaper according to the present embodiment is configured as described above. Since it does not cover more than necessary, absorption inhibition does not occur. Furthermore, with the conventional simple outward-facing three-dimensional guard, if the excretion rate of urine etc. is fast,
Although the momentum may exceed the three-dimensional guard, in the present embodiment, such a problem does not occur because the lower wall portion faces inward.

In addition, since the three-dimensional guard 7 stands up as described above, the fitting property is improved, and the contact area between the constituent members of the disposable diaper and the skin of the wearer is increased, so that the leak preventing property is improved. . Further, since a pocket portion is formed between the three-dimensional guard 7 and the side flap portion, even if the body fluid leaks out beyond the three-dimensional guard 7, the body fluid can be received by the pocket portion, which is more effective. Leakage can be prevented. In addition, since the three-dimensional guard 7 is configured as described above, even when leg gathers are formed, the function of the leg gathers is not hindered, and the three-dimensional guards 7 and the leg gathers can effectively be used from the side. Leakage can be prevented. Furthermore, if the leg gathers are shorter than the three-dimensional guard, the three-dimensional guard effectively faces inward during mounting, so that a more desired effect can be exhibited. In short, in the disposable diaper 1 of the present embodiment, the three-dimensional guard 7 is formed as described above, and stands up in use in the above-described manner in use. It is excellent in fitting property, and as a result, leakage prevention is further improved.
