乳幼児用、又は失禁者用おむつとして供される立体パン
ツ型おむつに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a three-dimensional pants-type diaper that is used as a diaper for infants or incontinent persons.
従来あらかじめ立体的なパンツ型に形成され、ウェスト

する使い捨て吸収パンツが特開昭５７−７７３０４号公
報において提案されている。Conventionally, disposable absorbent pants have been proposed in JP-A-57-77304, which are formed in advance into a three-dimensional pant shape and have stretchable elastic members in the waist portion and a pair of openings for inserting legs.
前記公知技術によればウェスト部、足挿入用開口部に伸
縮弾性部材が裏面シートと表面シートに別途取り付けら
れており、これは製造工程が複雑となり、生産性が上が
らない。According to the known technique, elastic members are separately attached to the back sheet and the top sheet at the waist portion and foot insertion opening, which complicates the manufacturing process and does not improve productivity.
又、裏面シートと表面シートに大きな伸縮弾件部材を別
途取り付けねばならないため、製造コストが大となり、
生産効率が悪く、しかも装着時のフィツト性に問題があ
った。In addition, large elastic members must be attached separately to the back sheet and top sheet, which increases manufacturing costs.
Production efficiency was poor, and there were also problems with fit during installation.
更に、使用後の取り外しを容易にするため、腰部両側部
に引き裂き用の糸が設置されているが、−回引き裂いて
しまうとおむつとして再度使用できないので、おむつ内

問題もあった。Furthermore, tearing strings are installed on both sides of the waist to make it easier to remove after use, but if the diaper is torn twice, it cannot be used again, so it is necessary to tear it multiple times to check the condition inside the diaper. There was also the problem that the attachment could only be removed.
本発明者らは、上記問題点を解決するべく、鋭意研究を
重ねた結果、本発明を成すに至った。The present inventors have conducted extensive research in order to solve the above-mentioned problems, and as a result, have accomplished the present invention.

シートを使用することにより上記問題点を解決できるこ
とを見出した。That is, it includes a liquid-impermeable back sheet, a liquid-permeable top sheet, and an absorbent body disposed between the two sheets,
In a three-dimensional pants-type disposable diaper, the sides extending from the waist part to the opening for inserting the legs are adhesively closed on both sides of the two sheets. A flexible film with stretchable elastic properties is used as the liquid-permeable top sheet, or a flexible film without stretchable elastic properties is used as the liquid-impermeable back sheet. The above-mentioned problems are solved by using a sheet made by joining together a non-woven fabric that does not have elastic properties and a non-woven fabric that has elastic properties as a liquid-permeable top sheet. I found out what I can do.
更にウェスト部位において少なくとも一カ所を開閉自在
とすることによって、上記問題点を解決できることを見
出した。Furthermore, it has been found that the above-mentioned problems can be solved by making at least one part of the waist part openable and closable.

(See FIG. 4), or a material having stretchable elasticity is joined on one side (see FIG. 5). The width of each material having both of these properties is determined by the width a of the top sheet or back sheet (see Figure 4) when joining a material with stretch elastic properties on both sides of a material without stretch elastic properties. The width of the material with elastic properties on one side is 10% to 4
0%, 80% to 20% width of material that does not have elastic properties

着剤で接着し積層体を作成する。A hot melt adhesive 6 for internal adhesion is continuously applied to a back sheet 4 made of a flexible film sheet having stretchable elastic properties. Next, separately prepared absorbent bodies 7 are continuously placed on the backsheet at intervals corresponding to one diaper, and then a topsheet 5 made of a nonwoven fabric with stretchable elasticity is layered on top of the absorbent body 7, which has been previously applied with hot water. Create a laminate by bonding with melt adhesive.

なわち対象とする赤ちゃんの月齢に合せて、該足挿入用
開口部の直径は決定する必要がある。The foot insertion opening 3 has a diameter of 50 mm to 150 mrn in the state of each diaper (if the shape of the opening is not circular, the approximate diameter when the opening is deformed into a circular shape). The diameter of the foot insertion opening must be determined according to the size of the product to be manufactured, that is, the age of the target baby.
該足挿入用開口部の直径は装着する赤ちゃんの腿の直径
に対して小さすぎると肌に赤い跡が付き、大きすぎると
股からの漏れが生じやすく成り、開口部の直径は製品品
質を決定する重要な要因である。If the diameter of the foot insertion opening is too small relative to the diameter of the baby's thigh, red marks will appear on the skin, and if it is too large, leakage from the crotch will easily occur.The diameter of the opening determines the quality of the product. This is an important factor.
