本発明は、股下領域を幅狭く、かつ、該領域の対向側に
ポケット部分を形成した使い捨ておむつの製造方法に関
する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for manufacturing a disposable diaper having a narrow crotch region and a pocket portion formed on the opposite side of the crotch region.
従来、着用者への適合性をよくするため、おむつの股下
領域の対向側を切除することにより、該領域を幅狭く形
成したものが知られている。Conventionally, diapers have been known in which the opposite sides of the crotch region of the diaper are cut out to make the region narrower in order to improve suitability for the wearer.
一方、着用者の脚回りから排泄物が漏れるのを防１にす
るため、おむつの対向側を内側へ折り返し、その折り返
し部分を対向端において接合することにより、股下領域
の対向側にポケット部分を形成したものが知られている
。On the other hand, in order to prevent excrement from leaking from around the wearer's legs, the opposite side of the diaper is folded inward and the folded parts are joined at the opposite ends to create a pocket part on the opposite side of the crotch area. What was formed is known.
前記前者は、おむつの股下領域の対向側を切除するので
その切除部分の素材が無駄になる。In the former method, the opposite side of the crotch area of the diaper is cut off, so the material of the cut portion is wasted.
一方、前記後者は、おむつの対向側の全体を単に均等幅
にわたって内側へ折り返すので、外観が良好であるとは
いえないばかりでなく、かように巾に折り返すだけでは
股下領域だけを幅狭く形成することができず、かりに、
かように形成しようとすれば、その折り返し部分の外側
を切除する必要があり、前記同様に素材が無駄になる。On the other hand, in the latter method, the entire opposite side of the diaper is simply folded inward over an equal width, which not only does not give a good appearance, but also makes only the crotch area narrower if the diaper is simply folded back to the width. Unable to do so,
If it were to be formed in this way, it would be necessary to cut out the outside of the folded portion, which would waste material as described above.
したがって、本発明の主たる目的は、対向側を内側へ折
り返し、その折り返し部分の対向端を接合することによ

く形成すると同時に、該領域の対向側にポケット部分を
形成することができ、しかも、該対向側に伸縮弾性部材
を取り付けた使い捨ておむつの製造方法をうることにあ
る。Therefore, the main object of the present invention is to fold the opposing sides inward and join the opposing ends of the folded portions to form a narrower crotch area without wasting any material, while at the same time It is an object of the present invention to provide a method for manufacturing a disposable diaper in which a pocket portion can be formed on one side and a stretchable elastic member is attached to the opposite side.

おむつの製造方法に存する。The gist of the means of the present invention for achieving the above object is that an absorbent core having a smaller profile than the front and back sheets is placed between a water-permeable top sheet and a water-impermeable back sheet. The front and back sheet portions are interposed so as to extend outward from the opposing side edges to form a flap, and a stretchable elastic member is attached to the outer portion of the flap in the crotch region, and the inner edge of the stretchable elastic member and the core A slit line is provided that extends from the opposite end of the flap portion between the outer edge to the vicinity of each end of the stretchable elastic member and is bent toward the core side, folding the flap portion inward and joining the folded portion in a front region and a dorsal region;
Thereby, the method for manufacturing a disposable diaper is characterized in that the crotch region is formed narrower than the front region and the back region, and at the same time, a pocket portion is formed on the opposite side of the crotch region.
さらに１本発明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。Further, the present invention will be explained based on the illustrated embodiment.
It is as follows.

ア３を該コアの外周縁から該表裏面シート部分が外側へ
延出してフラップ４．５を形成するように介在させる。As shown in FIG. 1, a water-permeable top sheet 1 and a water-impermeable back sheet 2 are formed by cutting rectangles of appropriate size from these original sheets. An absorbent core 3 having a smaller rectangular outline than these is interposed so that the front and back sheet portions extend outward from the outer periphery of the core to form flaps 4.5.
この場合、少なくとも表裏面シート１．２が相合する外

介在させてもよい。A stretchable elastic member 9 is attached to the opposite side of the joined crotch region 6, that is, the outer part 5a of the flap 5, the outer part is folded back inward, and the folded part is joined with the adhesive or welding means. Naturally, the stretchable elastic member 9 is formed by forming the back sheet 2 to a size that slightly extends from the opposite side edge of the top sheet 1 and covering the extended portion by folding it inward, or by covering the front and back sheets 1, 2. It may be interposed between.

ト部分１４が形成される。As shown in FIGS. 2 and 3, a straight line extends from the opposing end of the portion of the flap 5 between the inner edge of the elastic member 9 and the outer edge of the core 3 to the vicinity of each end of the elastic member 9. A slit line 10 is provided which is bent into an arc toward the core 3 side. m1 connecting between the slit line 10 and the opposing inner ends of the slit line
1 and the flap portion 12 outside these lines.
Fold back inward, and fold the folded part 12 into the front area 7.
and the dorsal region 8 using the adhesive or welding means. Cross-sectional views of the respective parts of the diaper thus joined are shown in FIGS. 5 to 7. Especially Figures 3 and 6
As is clear from the figure, at the same time that the recessed portion 13 is formed to narrow the crotch region, a pocket portion 14 is formed on the opposite side of the region.

あるのは外観と着用性をよくするためである。As shown in FIG. 4, the thus formed diaper has a concave notch 15 formed by shaving inward an arcuate central portion along the outer edge of the front region, and a central portion along the outer edge of the back region. A convex portion 16 having the same shape and size as the concave notch portion 15 is formed so as to extend outward in an arc shape at a portion facing the concave notch portion 15, and further includes a front region, a dorsal region, and an inseam region. In this case, in order to use the materials of the front and back sheets 1 and 2 without wasting them, it is necessary to cut the front and back sheets from their original sheets. , recessed part 15
Incidentally, the concave portion 15 is provided to prevent the diaper from hitting the newborn baby's body, and the convex portion 16 is provided to prevent excretion from the central region of the dorsal region. Each is provided to prevent things from leaking. Furthermore, the reason why the outer edge of the diaper is curved except for a part is to improve the appearance and wearability.

The core 3 can be made of cotton-like pulp, a mixture of this and superabsorbent polymer particles, and in some cases, unlike the rectangular shape shown, the front region and the back region are closer to the crotch region. It may also be formed in a wide range.

がきわめて簡易である。According to the manufacturing method of the diaper of the present invention, as described above, by folding the opposite side inward through the slit line and joining each end of the folded part, only the crotch area can be narrowed, and at the same time, the crotch area can be narrowed. Pocket portions having stretchable elastic members can be formed on opposite sides of the region. Therefore, not only does it have a good appearance, but the above-mentioned problems can be solved without wasting any material, and the manufacturing method for a diaper having such a configuration is extremely simple.
