いる。2. Description of the Related Art Conventionally, it has been well known as a conventional technique to use a liquid-impermeable plastic film such as a polyethylene film as an outer sheet of a disposable diaper. Further, Japanese Patent Laid-Open No. 3-86159 discloses a technique of using a composite sheet composed of a plastic film and a nonwoven fabric bonded to the outer surface thereof as the outer surface sheet.

の脚周りへの密着性が低下し、体液が漏れ易くなる。In the conventional diaper using a plastic film for the outer sheet, the user may sometimes dislike the soft touch peculiar to the plastic film. As taught in the above publication, a composite sheet in which a nonwoven fabric is bonded to the outer surface of such a film,
The outer surface of the diaper feels like cloth, eliminating the film-specific problems. However, when the outer sheet is such a composite sheet, the rigidity is higher than in the case where only the film is used, and gathers generated by contraction of the elastic members around the waist and legs tend to have a relatively large pitch. is there. If the gathers have a large pitch around the legs, in other words, if the gathers around the legs are not finely gathered, the adhesion of the diaper around the legs is reduced, and body fluid easily leaks.

こと、にある。In order to solve the above problems, in the present invention, a liquid-permeable inner surface sheet, and a liquid-impermeable outer surface sheet in which a fibrous nonwoven fabric is integrally bonded to the outer surface of a plastic film, A laminate is composed of the liquid-absorbent core interposed between these sheets, and elastic legs interposed between the inner and outer sheets along curved leg circumferences formed on both sides of the central region of the laminate. It is premised on a disposable diaper provided with a peripheral elastic member. In such a premise,
The present invention is characterized in that the fibrous nonwoven fabric is composed of hydrophobic fibers and has a water pressure resistance value of 20 mm.
Above, the plastic film is cut out along the leg periphery where the elastic member is located, and the inner edge and the leg periphery of the elastic member farthest from the outer edge of the leg periphery. The outer edge of the plastic film portion of the portion is separated by 5 to 35 mm, and the elastic member is interposed between the inner surface sheet and the nonwoven fabric.

Is composed of an inner surface sheet 2 on the skin contact side, an outer surface sheet 3 on the non-skin contact side, and a liquid-absorbent core 4 interposed between these sheets 2 and 3, and includes a front waist region 6 and a rear waist region. It has an area 7 and a crotch area 8 located between these areas 6, 7. The inner and outer sheets 2, 3 are joined at the portions extending from the four circumferences of the core 4, and are located on the left and right sides of the crotch region 8 and the front and rear waistline peripheral edge portions 10, 11 and the front and rear waistline side edge portions 12, 13. Leg part 14
And the leg portions 14 are curved inwardly of the diaper. The front and rear waist circumference edge portions 10 and 11 and the leg circumference portion 14 have three waist elastic members 1 between the inner and outer sheets 2 and 3.
6 and 17 and three leg elastic members 18 are arranged, and these elastic members 16, 17 and 18 are joined to the inner surface of one of the seats 2 and 3 in an extended state. Tape fasteners 19 that are attachable to and detachable from the front waistline side edge portions 12 extend from the left and right rear waistline side edge portions 13.

い。The outer sheet 3 includes a fibrous nonwoven fabric 22 having substantially the same shape and size as the inner sheet 2, and a liquid-impermeable or breathable liquid-impermeable plastic film 21 integrally bonded to the inner surface of the nonwoven fabric 22. It is composed by. Film 2
1 has the same shape and size as the non-woven fabric 22 except for the leg-surrounding portion 14, and in the leg-surrounding portion 14, the outer edge of the film 21 is more inward than the side edge of the non-woven fabric 22 and has three strips (A ,
Among the elastic members 18 of (B, C), the inner edge of the elastic member C farthest from the outer edge of the leg periphery is separated by 5 to 35 mm. If the separation distance is less than 5 mm, it depends on the relative relationship between the rigidity of the core 4 and the extension stress of the elastic member 18,
In the case of the core and the elastic member that are generally used in this kind of diaper, the elastic member is difficult to contract so that the circumference of the wearer's leg can be sufficiently tightened due to the rigidity of the core.

る。FIG. 2 is a sectional view taken along line II-II of FIG. In the leg surrounding portion 14, the three elastic members 18 are interposed between the inner surface sheet 2 and the non-woven fabric 22. The non-woven fabric 22 is made of a hydrophobic fiber so that body fluid does not exude from the non-woven fabric 22 at the leg-surrounding portion 14, and the JI
It has a water pressure resistance value of 20 mm or more based on S L 1092.

数にすることができる。In the diaper 1 thus constructed, the outer sheet 3 is entirely made of the non-woven fabric 22 and has the feel of the cloth, and the film 21 is bonded to the inner surface of the non-woven fabric 22 to cause fluid leakage. There is no. The outer sheet 3 in which the non-woven fabric 22 and the film 21 are joined has a relatively high rigidity, but the legs 21 lack the film 21 and have a low rigidity. Therefore, when the leg elastic member 18 contracts, relatively fine gathers are generated in the leg portion 14, and the adhesion to the leg is improved as compared with the case where the film 21 exists there. For joining the non-woven fabric 22 and the film 21, an adhesive such as a hot melt adhesive or a heat welding technique can be used, as in the case of joining other members of the diaper 1. The elastic members 16, 17, 18 around the waist and the legs are not limited to the illustrated examples, and the required number can be set.

たりすることがない。In the diaper according to the present invention, since the outer sheet is composed of the non-woven fabric and the plastic film, it feels like a cloth and does not leak body fluid. Since the plastic film of the outer sheet is removed from the leg-surrounding portion, fine gathers that have good breathability, are flexible, and easily adhere to the skin are generated. in addition,
Since the non-woven fabric of the outer sheet has a water pressure resistance value of 20 mm or more, excrement does not easily leak or exude in the leg parts.
