Description of the Related Art Conventionally, it is a conventional technique to use a liquid-impermeable plastic film such as a polyethylene film as a liquid-impermeable outer sheet of a disposable diaper. Further, Japanese Patent Application Laid-Open No. 3-86159 discloses a technique in which a composite sheet comprising a plastic film and a fibrous nonwoven fabric bonded to the outer surface is used as the outer sheet.

脚周りへの密着性が低下し、体液が漏れ易くなる。In the diaper of the conventional technique using a plastic film as an outer sheet, the touch peculiar to the plastic film may be disliked by consumers. As taught in the above publication, if the outer surface of such a film is a composite sheet covered with a nonwoven fabric, the outer surface of the diaper will feel like a cloth and the problem unique to the film will be solved. However, when the outer sheet is such a composite sheet, the rigidity is higher than when only the film is used, and the pitch of the gathers generated by contraction of the elastic members around the waist and the legs is relatively large. If the gather pitch is large around the legs, in other words, if fine gathers are not obtained around the legs, the diaper will have reduced adhesion to the surroundings of the legs and the body fluid will easily leak.

５ｍｍ離間していることにある。In order to solve the above-mentioned problems, the present invention provides a liquid-permeable inner sheet, a liquid-impermeable outer sheet in which a fibrous nonwoven fabric is integrally joined to the outer surface of a plastic film, and A laminate is formed from the liquid-absorbent core interposed between the two sheets, and the elastic leg surroundings interposed between the inner and outer sheets along curved leg peripheries formed on both sides of the central region of the laminate. It assumes a disposable diaper with an elastic member. On this assumption, the present invention is characterized in that the non-woven fabric is missing along the leg periphery where the elastic member is located, and from the outer edge of the leg periphery in the elastic member. The inner edge of the furthest one is 5 to 3 times the outer edge of the non-woven portion around the leg.
That is, they are separated by 5 mm.

Is composed of an inner sheet 2 on the skin contact side, an outer sheet 3 on the non-skin contact side, and a liquid-absorbent core 4 interposed between these two sheets 2, 3. It has a region 7 and a crotch region 8 located between both regions 6 and 7. The inner and outer sheets 2 and 3 are joined at portions extending from the four circumferences of the core 4 to form front and rear waist edges 10, 11, front and rear waist side edges 12 and 13, and leg circumferences 14. The leg circumference 14 is curved inwardly so as to easily fit around the wearer's leg. Between the inner and outer sheets 2, 3 along the front and rear waist edges 10, 11 and the leg circumference 14, three waist elastic members 16, 17 are provided around the front and rear waist, and 3 are provided around the left and right legs. An elastic member 18 around the leg is disposed, and the elastic members 16, 17, 18

Have been. The film 21 has substantially the same shape and the same size as the inner sheet 2, and the nonwoven fabric 22 has the same shape and the same size as the film 21 except for the leg surroundings 14. The non-woven fabric 22 is missing in the leg surrounding portion 14, and the curved outer edge 26 of the non-woven fabric 22 has the inner edge of the three leg elastic members 18 farthest from the outer edge of the leg surrounding portion 14. And a distance D of 5 to 35 mm.

Then, the outermost part of the front and rear waist regions 6, 7 and the inseam region 8 where the wearer's or mother's hand often touches is the nonwoven fabric 22, which is soft to the touch of the cloth. No exudation of However, the leg circumference 14 is
Since the nonwoven fabric 22 is absent and only the plastic film 21 is present, the rigidity of the outer sheet 3 is low due to the absence of the nonwoven fabric 22. When the elastic member 18 contracts, relatively fine gathers are generated here, so that the diaper 1 has good adhesion around the legs, and thus has good leak-proof performance. Nonwoven fabric 22
Distance D between the outer edge 26 of the elastic member 14 and the inner edge of the elastic member 14
Is preferably in the range of 5 to 35 mm in a stretched diaper, and a relatively large distance D is applied to an adult diaper. If the separation distance D is less than 5 mm, the core 4
Depending on the relative relationship between the rigidity of the elastic member and the elongation stress of the elastic member 14, in the case of the core and the elastic member generally used in this type of diaper, the elastic member sufficiently surrounds the leg around the wearer due to the rigidity of the core. Hard to shrink so that it can be tightened. The bonding between the nonwoven fabric 22 and the plastic film 21 can be performed by using an adhesive such as a hot-melt adhesive or by using a heat welding technique, as in the case of bonding the other members of the diaper 1.

ャザーが生じる。In the diaper according to the present invention, the outer sheet is composed of a plastic film and a nonwoven fabric, and the nonwoven fabric covers the front and rear waist region and the crotch region, while the nonwoven fabric is cut off at the leg circumference. In the portion, the outer edge of the nonwoven fabric and the inner edge of the leg-surrounding elastic member are separated by 5 to 35 mm. Therefore, the outer surfaces of the front and rear waist regions and the crotch region of the diaper become soft to the touch of the cloth, and fine gathers are generated around the legs, which are flexible and easily adhere to the skin.
