いる。As is well known, disposable diapers have fluff pulp mats, absorbent paper, or super absorbent polymers between a liquid-impermeable back sheet made of polyethylene and a liquid-impermeable top sheet made of nonwoven fabric such as polyester. It is equipped with an absorbent body consisting of, and elastic bodies are provided around the waist and leg openings. Furthermore, a fastener tape for connecting the back side part and the front side part is installed at the waist end of the back side part.

A stretchable elastic body was installed between the top sheet and the back sheet along both edges of the absorbent body. In such S-suits, it is difficult to prevent excrement floating on the top sheet, such as urine and soft feces containing a lot of water, from leaking through the elastic elastic part of the crotch. There was a risk of staining clothes.

が難しい、という問題点があった。On the other hand, as a gearer installed in the setup, not only a stretchable elastic body is installed between the top sheet and the back sheet, but also a nonwoven fabric to which the stretchable elastic body is attached is installed parallel to the side edge of the absorber and the crotch gearer. Although a method to do this has also been proposed (
JP 61-296103, JP 62-25021,
According to this method, it is easy to prevent excrement floating on the top sheet from leaking out, but due to the manufacturing process, the elastic body is attached to the diaper body in two parts. Therefore, there is a problem that the number of work steps increases and it is difficult to improve the efficiency.

産効率の向上が難しい、という問題点があった。(Problems to be solved by the present invention) As mentioned above, in conventional diapers in which a stretchable elastic body is installed only between the top sheet and the back sheet, floating excrement on the top sheet leaks to the outside of the diaper. Furthermore, in addition to conventional crotch gears, diapers in which non-woven fabric with stretchable elastic bodies is added in parallel to the side edges of the absorbent body are used to remove excrement floating on the top sheet. Although it is possible to prevent leakage, there is a problem in that it is difficult to improve production efficiency because the process of attaching the stretchable elastic body is divided into two steps in the diaper manufacturing process.

ていることを特徴とする使いすておむつである。(Means for solving the problems) The present invention provides a disposable diaper having an absorbent body between a liquid-permeable top sheet and a liquid-impermeable back sheet.
It has side flaps extending outwardly from both lateral edges of the absorbent body and made of the back sheet and a hydrophobic nonwoven fabric, and the edges of the hydrophobic nonwoven fabric in the inside direction of the diaper extend over the entire length in the longitudinal direction of the diaper. The absorber is bent to form a leak-proof part made of a hydrophobic non-woven fabric whose base end is on the surface sheet at the longitudinal side edge of the absorbent body and extends upward, and a stretchable elastic part is formed near the tip and base end of the leak-proof part. The body is attached to the body, and the leakage preventive portion is tilted toward the inside of the diaper at both ends in the longitudinal direction of the diaper, that is, the back region and the abdominal region, and is adhesively fixed onto the liquid-permeable top sheet on the absorbent body. This disposable diaper is characterized by:
すなわち、本発明は、上方へ延びた防漏部（アッパーフ

れる。That is, in the present invention, since the leak-proof part (upper flap part) extending upward is made of a hydrophobic non-woven fabric, the leak-proof part has air permeability, which improves swelling. The leak prevention part is tilted inwardly of the diaper at the part,
Since it is adhesively fixed onto the top sheet on the absorbent body, a pocket portion is formed between the top sheet on the absorbent body and the leak prevention portion (upper flap portion), and an improvement in leak prevention is realized.
本発明の使いすておむつにおいては、防漏部層端部近傍
にも伸縮弾性体が取りつけられ、上記防漏部と一体とな
って作用するため、漏れ防止効果が更に改善される。In the disposable diaper of the present invention, the elastic body is also attached to the vicinity of the end of the leak-proofing layer and acts integrally with the leak-proofing layer, thereby further improving the leak-preventing effect.
漏れ防止部の基部はサイドフラップ上に設けるよりも吸
収体上の表面シート上に設け、吸収体上の表面シート上
にポケット部を作る方が漏れ防止上より効果的である。It is more effective in preventing leakage to provide the base of the leak prevention portion on the top sheet on the absorbent body and to form the pocket portion on the top sheet on the absorbent body, rather than on the side flaps.

While moving the hydrophobic nonwoven fabric in the longitudinal direction, apply an adhesive to the part corresponding to the crotch area, and attach the stretchable elastic body to the area where the adhesive has been applied in a stretched state, then turn the stretchable elastic body on the inside. After bending the ends of the nonwoven fabric to form a leak-proof part, the base of the leak-proof part is adhered to both edges of the top sheet, which is slightly wider than the absorbent body, and the leak-proof part is formed in the back region and abdominal region. Since the leak-proof part is manufactured by folding the parts inward and gluing them onto the top sheet, it is relatively easy to form and install the leak-proof part, and since the top sheet is slightly wider than the absorbent body, the side flaps The surface sheet used to form the section can be saved.

Because the body is installed, the fit when wearing the diaper is improved, and the elongation rate of the stretchable elastic body provided at the tip of the leak preventer can be reduced, or a relatively thin stretchable elastic body can be used. Because it can be used, it won't tighten your skin.

成されている。FIG. 2 is a cross-sectional perspective view taken along line xx' in FIG. 1. The side flap 7 consists of a front side sheet 2 and a back sheet 3 pasted together, and the front side sheet has a front sheet (front center sheet) 1 at the side edge of the absorbent body.
A leak prevention part 8 is formed at the inner end of the diaper.
表面サイドシートは疎水性不織であるのが好ましく、そ
の疎水性の目安は、流下長測定法により５ｃｍ以上あっ
たほうが漏れ防止効果が太きい。The surface side sheet is preferably made of hydrophobic non-woven material, and as a guideline for its hydrophobicity, the leakage prevention effect is greater when the hydrophobicity is 5 cm or more according to the flow length measurement method.
流下長測定法は２０℃、６５％ＲＨ雰囲気において次の
ように実施する。The flow length measurement method is carried out at 20° C. and in a 65% RH atmosphere as follows.

節しなければならない。The suitable method for attaching the stretchable elastic body to the leakage prevention part (upper flap) is to use hot melt adhesive, and in the case of urethane foam sheets, the adhesive strength is 150 to 250%.
It is preferable to bond the elastic body in a stretched state within the range of . If the stretch rate is less than 150%, no pocket will be formed between the top sheet on the absorbent body and the upper flap, and the contact against the baby's thighs will be weak, reducing the leakage prevention effect. On the other hand, if the elasticity is high (250% or more), it will dig into the baby's skin when the diaper is worn, causing problems. The other materials also need to have a stretch rate that is sufficient to form a pocket, and must be adjusted to a range that is not too strong.
