【発明の詳細な説明】 〔産業上の利用分野〕 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。Description: TECHNICAL FIELD The present invention relates to a method for manufacturing a disposable diaper in which a crotch region is narrow and a pocket portion is formed on the opposite side of the 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, in order to improve suitability for a wearer, it is known that the inseam region of the diaper is cut off at the opposite side to form the region narrowly.
一方、着用者の脚回りから排泄物が漏れるのを防止する
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 the excrement from leaking around the legs of the wearer, the opposite side of the diaper is folded back inward, and the folded portion is joined at the opposite end to form a pocket portion on the opposite side of the crotch region. Things are 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 case, the opposite side of the crotch region of the diaper is cut, so that 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、かように単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, the latter is not only not good in appearance because the entire opposite side of the diaper is simply folded back inward over a uniform width, and the crotch region is formed to be narrow only by simply folding back. I couldn't do that,
If such an attempt is made, it is necessary to cut the outside of the folded-back portion, and the material is wasted as in the 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

る。Therefore, the main object of the present invention is to fold back the facing side inward and join the facing ends of the folded back portions to form a narrow crotch region without wasting any material, and at the same time, facing the facing region. It is to obtain a method for manufacturing a disposable diaper in which a pocket portion can be formed on the side and an elastic elastic member is attached on the opposite side.

存する。The gist of the means of the present invention for achieving the above-mentioned object is to provide an absorbent core having a contour smaller than that of the front and back sheets between the water-permeable top sheet and the impermeable back sheet at least in the core. The front and back sheet portions extend outward from the opposite side edges to form a flap, and an elastic elastic member is attached to an outer portion of the flap in the crotch region, and the flap near each end of the elastic elastic member. A slit line extending from an outer edge of the flap to a substantially central portion of the flap is provided, the flap portion between the slit lines is folded inward through the slit line, and each end of the folded portion is joined. As a result, the crotch region is formed to be narrower than the front side region and the back side region, and at the same time, a pocket portion is formed on the opposite side of the crotch region. It resides in the method of manufacturing a disposable diaper to be.
さらに、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 described based on the illustrated embodiment,
It is as follows.

合する。As shown in FIG. 1, a water-permeable top sheet 1 and a water-impermeable back sheet 2 are formed by cutting the original sheet into squares of appropriate sizes. Between the front and back sheets 1 and 2,
The absorbent core 3 formed in a rectangular shape having a smaller contour than these is interposed so that the front and back sheet portions extend outward from the outer peripheral edge of the core to form flaps 4 and 5. In this case, at least in the outer peripheral region where the front and back sheets 1 and 2 meet and the region where the front and back sheets and the core 3 are in contact with each other, for example, a hot melt adhesive applied in a stripe shape is used for joining.

させてもよい。The elastic elastic member 9 is attached to the opposite side of the crotch region 6 thus joined, that is, the outer portion 5a of the flap 5, the outer portion is folded back inward, and the folded portion is joined by the adhesive or the welding means. Naturally, the elastic elastic member 9 is formed by forming the backsheet 2 into a size slightly extending from the opposite side edge of the topsheet 1 and covering it by folding back the extending portion inward. You may intervene between.

形成される。As shown in FIGS. 2 and 3, arc-shaped slit lines 10 are provided from the outer edge of the flap 5 in the vicinity of each end of the elastic member 9 to the approximate center of the flap. The flap portion 12 is folded back inward through the slit line 10 and the line 11 connecting between the opposing inner ends of the slit line, and each end of the folded portion 12 is joined by the adhesive or welding means. Sectional views of the respective parts of the diaper thus joined are as shown in FIGS. 5 to 7. In particular, as apparent from FIGS. 3 and 6, the recessed portion 13 is formed to narrow the width of the crotch region, and at the same time, the pocket portion 14 is formed on the opposite side of the region.

して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 diaper thus formed has a recessed portion 15 formed by arcuately forming a central portion along the outer end in the front side region in an arc shape, and a center along the outer end in the back side region. A convex portion 16 having the same shape and size as the concave portion 15 is formed so that the portion facing the concave portion 15 extends outward in an arc shape, and further, the front region, the dorsal region, and the crotch region. The outer edge of the corner angle with may be formed as a curved line. In this case, in order to use the materials of the front and back sheets 1 and 2 without waste, when the front and back sheets are cut from those raw sheets, the recessed portions 15 and the protruding portions 16 are formed. It may be done. By the way, the recessed portion 15 is provided to prevent the diaper from hitting the navel of the newborn baby, and the protruding portion 16 is provided to prevent the excrement from leaking from the central portion of the dorsal region. Further, the outer edge of the diaper is formed in a curved shape except for a part thereof in order to improve appearance and wearability.
