Definitions
- the present invention relates to an absorbent article, and more particularly to absorbent articles such as disposable diapers, defecation training pants, and incontinence briefs.
- Unexamined-Japanese-Patent No. 2004-298643 (patent document 1) is well-known, for example.
- the diaper has a top sheet, a back sheet, and an absorber positioned between these sheets.
- a lotion is applied to the body side surface of the top sheet to reduce friction between the diaper and the wearer, thereby preventing skin problems of the wearer.
- the lotion can be transferred to the wearer's skin by bringing the top sheet to which the lotion is applied into contact with the wearer's skin. In this way, lotion is applied to the wearer's skin. In skin to which lotion is applied, this can serve as a barrier to prevent stool from adhering to the skin.
- Japanese Patent Laid-Open No. 2004-298643 Japanese Patent Laid-Open No. 2004-298643

- Conventional materials in this technical field such as a mixture of pulp and superabsorbent polymer particles, can be used.
- FIG. 6 shows the second embodiment, and is the same diagram as FIG. 3 of the first embodiment.
- front and rear waist sheets 54 and 55 are formed in the front and rear waist regions 7 and 8, and a lotion is applied to the front and rear waist sheets 54 and 55 to provide a third front application region 56 and a third rear application region. 57 is further formed.
- the front and rear waist sheets 54 and 55 extend in the lateral direction X substantially parallel to the front and rear end edges 2a and 2b of the chassis 2 forming the waist opening 18.
- the front and rear waist sheets 54 and 55 are formed so as to overlap the front and rear end edges 23a and 23b of the liquid absorbing structure 23, respectively, but are shifted in the longitudinal direction Y so as not to overlap the liquid absorbent core 25. Be placed.
- front and rear waist sheets 54 and 55 in addition to a general water-repellent nonwoven fabric and a hydrophilic nonwoven fabric, a nonwoven fabric containing an antibacterial agent can be used.
- the front and rear waist sheets 54 and 55 are coated with lotion to form third front and rear application areas 56 and 57.
- the application amount of the lotion is about 3 to 15 g / m 2 , preferably about 10 g / m 2 .
- the front and rear waist regions 7 and 8 are often in contact with the wearer's belly or back when the diaper 1 is worn. Therefore, when the front and rear waist sheets 54 and 55 are formed in the front and rear waist regions 7 and 8, the front and rear waist sheets 54 and 55 come into contact with the wearer's skin. By forming the third front and rear application regions 56 and 57 at the contact portion with the skin, skin troubles due to friction with the diaper 1 can be reduced. Further, since the liquid-absorbent core material 25 and the front and rear waist sheets 54 and 55 are arranged so as not to overlap, the liquid-absorbent core is formed by the third front and rear application areas 56 and 57 formed on the front and rear waist sheets 54 and 55. Absorption of body fluid into the material 25 is not hindered.
- the third front and rear application areas 56 and 57 are formed in addition to the first and second application areas 51 and 52, the skin trouble of the wearer can be further prevented.
- the third front and rear application regions 56 and 57 are formed on the front and rear waist sheets 54 and 55 different from the chassis 2, they may be formed directly on the chassis 2.

Abstract
Description
また、トップシートは必ずしも着用者の肌に接触するとは限らず、トップシートが肌に接触しなければローションを肌に移行させることができない。ローションが肌に移行されなければ、肌への便等の付着を抑制するという機能を発揮することができない。
前記離隔シートには前記中間部分にローションが塗布された第1塗布領域が形成され、前記シャーシには前記連通部から露出する部分に前記ローションが塗布された第2塗布領域が形成されたことを特徴とする。
シャーシであって離隔シートの連通部から露出する部分にもローションが塗布された第2塗布領域を形成することとしたので、連通部以外の部分ではローションが塗布されることなく、シャーシの全面に亘ってローションが塗布されることがない。ローションが塗布されない部分を形成することによって、シャーシにおける体液の透過性を阻害することがなく、体液が漏れるのを防止することができる。

図1~5は第1の実施形態を示したものである。図1はおむつ1の着用状態を示した図である。図示したように、おむつ1はシャーシ2と離隔シート3と漏れバリアカフ4とを含む。シャーシ2はパンツ型に形成され、身体側内面5および着衣側外面6と、前ウエスト域7、後ウエスト域8および前記前後ウエスト域7,8間に位置するクロッチ域9を含んでいる。前ウエスト域7からクロッチ域9を通って後ウエスト域8へと向かう方向を縦方向Yとし、これに直交する方向を横方向Xとしている。シャーシ2は、内面シート11と外面シート12と、これら内外面シート11,12の間に介在する不透液性の漏れバリアシート13と、内面シート11に積層された吸液構造体10とによって形成されている。
接合部16でウエスト側縁部14,15が接合されることにより、前後ウエスト域7,8で囲まれた領域にウエスト開口18が形成されるとともに、レッグ側縁部17で囲まれた一対のレッグ開口19が形成されている。ウエスト開口18の周縁部に沿って複数条のウエスト弾性部材20が延び、レッグ開口19の周縁部に沿って複数条のレッグ弾性部材21が延びている。それら弾性部材20,21は、内面シート11と外面シート12との間にあり、これらシート11,12の少なくとも一方に接着剤(図示せず)を介して伸長状態で接合されている。
離隔シート3は、少なくとも前後端縁27,28においてその両側部分30,31で折り返された部分を吸液性パネル23の身体側ライナ26に接着剤40を介して接合している。
離隔シート3と漏れバリアカフ4とは、前後方接合部位48,49において互いに接合される。前後方接合部位48,49は、離隔シート弾性部材39に重なる位置に形成されている。
吸液性パネル23から離間した離隔シート3の中間部分32には第1塗布領域51が形成され、この第1塗布領域51が着用者の肌に当接するので、ローションを着用者の肌に確実に移行させることができる。おむつ1は、離隔シート3の前方連通部33が着用者の外性器に位置し、後方連通部34が肛門に位置するように着用状態を整えるようにして着用される。したがって、中間部分32は外性器と肛門との間の肌に接触する。この部分は特に刺激に弱い部分であり、かぶれ等が発症しやすい。この刺激に弱い部分にローションを塗ることができ、便等が付着して肌トラブルを起こすのを防止することができる。
離隔シート弾性部材39は、接着剤を介して離隔シート3に接合されるようにしているが、離隔シート3の中間部分32にローションを塗布することによって接着剤が剥がれてしまう可能性がある。したがって、中間部分32においては弾性部材39を接合する接着剤の量を多くすることが好ましい。
図6は第2の実施形態を示したものであり、第1の実施形態の図3と同様の図である。この第2の実施形態において、第1の実施形態と同様の構成要素については、その説明を省略する。この第2の実施形態では、前後ウエスト域7,8に前後ウエストシート54,55を形成し、この前後ウエストシート54,55にローションを塗布して第3前方塗布領域56と第3後方塗布領域57とをさらに形成している。前後ウエストシート54,55は、ウエスト開口18を形成するシャーシ2の前後端縁2a,2bにほぼ平行に横方向Xに延びている。前後ウエストシート54,55は、吸液構造体23の前後端縁23a,23bにそれぞれ重なるように形成されているが、吸液性芯材25には重ならないように、縦方向Yにずらして配置される。
