（産業上の利用分野）
本発明は、使い捨て着用物品に関し、さらに詳しくは、
オムツ・失禁パンツ・トレニングパンツなどの着用物品
に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to disposable wearing articles, and more specifically:
Concerning wearable items such as diapers, incontinence pants, and training pants.
従来のこの種の着用物品として、透液性トップシートと
透湿性・不透液性バックシートとの間に吸液性コアを介
在させ、股下区域の対向側部に、さらには前後身頃の少
なくとも一方の腰囲り部にも弾性部材を取り付けたもの
か知られている。Conventional wearing articles of this type include a liquid-absorbent core interposed between a liquid-permeable top sheet and a moisture-permeable/liquid-impermeable back sheet, and a liquid-absorbent core is interposed between a liquid-permeable top sheet and a moisture-permeable/liquid-impermeable back sheet, and the liquid-absorbent core is placed on opposite sides of the crotch area, and at least on the front and rear body parts. It is known that an elastic member is attached to one of the waist circumferences.
こうした公知の物品は、バックシートとして透湿性プラ

内部に起こる蒸れを少なくすることかできない、とくに
、この蒸れは、物品の腰囲り部および脚囲り部をそれぞ
れ対応の身体部位に弾性部材の収縮力て圧接させるパン
ツ型の物品において顕著になる。Although these known products use a moisture-permeable plastic film as a backsheet, the film does not have sufficient moisture permeability, so it is still not possible to reduce the stuffiness that occurs inside the diaper. Stuffiness becomes noticeable in pants-type articles in which the waist and leg circumferences of the article are brought into pressure contact with corresponding body parts by the contraction force of an elastic member.
ハックシートの透湿性を高くすると、蒸れも少なくなる
か、その反面、不透水性か低下して排泄液かハックシー
トから漏れることになる。こうした二律背反の問題を解
決することはきわめて困難である。Increasing the moisture permeability of the hack sheet will reduce stuffiness, but on the other hand, the water impermeability will decrease, allowing excreta to leak from the hack sheet. It is extremely difficult to resolve these trade-offs.
本発明の目的は、排泄液か排泄される部位から離れてい
て排泄液に接することか比較的少ない部位に通気孔群を
設けることて、内部における蒸れを極力少なくすること
かてきる物品を提供することにある。An object of the present invention is to provide an article that minimizes stuffiness inside by providing a group of ventilation holes in a part that is far from the part where excreted fluid is excreted and relatively rarely comes into contact with the excreted fluid. It's about doing.
前記目的を達成するための本発明物品は、伸縮性・透液

を有する使い捨て着用物品を前提とする。To achieve the above object, the article of the present invention comprises a pants body having a waist opening and a pair of leg openings from a stretchable, liquid-permeable top sheet and a stretchable, liquid-permeable back sheet, and The present invention assumes a disposable wearable article having an elastic member attached to each opening.

を貫通する通気孔群を設ける。Based on the above-mentioned premise, the present invention interposes a stretchable liquid barrier sheet in almost the entire area between the top and the hack sheet, and penetrates the top, hack, and barrier sheet on opposite sides of the front and back body excluding the crotch area of the diaper. Provide a group of ventilation holes.

。The group of ventilation holes may be provided also in the waist area of one of the front and rear bodies, and in addition to further increasing breathability, the top, back, and barrier sheet may be fused together at the inner peripheral edge of the ventilation hole. This is preferable in order to reduce the risk of damage to these sheets caused by the ventilation holes when the sheets are stretched.

ない。In the article of the present invention having the above configuration, the top, the
Ventilation inside and outside the article is measured through a group of ventilation holes penetrating the tank and the barrier sheet, making it possible to suppress stuffiness inside the article. The ventilation holes are located away from the center area of the crotch where excrement fluid is most likely to be excreted, and are located on the opposite sides and around the waist where contact with excrement fluid is relatively rare. There is little leakage of excretory fluid. Also,
The vent is reinforced by having the top, hack and barrier sheet portions fused together at the inner periphery of the vent, so that even if these sheets stretch when the article is worn, these sheets will not leak through the vent. It will not be easily damaged.

The article 1 is composed of a stretchable liquid-permeable top sheet 6, a stretchable liquid-permeable backsheet 7, a liquid barrier sheet 8, a mat or sheet-like core 9, and the elastic member 4.5. It is. On both side edges of the crotch area 12 located between the front and rear body parts 10° 11 of the top, hack and barrier sheets 6.7.8, there are recessed edges 13 forming the above-mentioned inter-leg section 13.Top. The sheet 6 is made of stretchable and liquid-permeable nonwoven fabric.
The back sheet 7 is made of the same material as the top sheet 6, and the barrier sheet 8 is made of vertically and horizontally stretchable plastic or rubber film. The barrier sheet 8 has better elasticity and higher elastic strength (stress) than the nonwoven fabric that is the material of the top and hack sheets 6.7. The inner surface of the top sheet 6 is coated with an adhesive or welding means (
The core 9 is bonded to the core 9 by a material (not shown), which does not impede the elasticity or flexibility of the bonded top sheet 6, and also allows the top sheet 6 to float away from the core 9. This is to ensure that the liquid permeability to 6 is not inhibited.
