Description

この発明に係る使い捨てのパンツ型おむつにおける体液吸収部は、両端部が被覆部の前胴回り域と後胴回り域との内面に接合する一方、両端部の間の部分は中央部の少なくとも一部分と両側部とが被覆部の股下域の内面に対して非接合状態にあるから、その非接合状態にある部分と被覆部との間には間隙が生じ得る。また、被覆部は、それが横方向へ弾性的に収縮することによって、外面および内面の少なくとも一方にギャザーが形成される。それゆえ、被覆部が収縮状態にあるときのおむつの股下域では、被覆部と体液吸収部との間の間隙、および被覆部に形成されたギャザーによって、体液吸収部は被覆部の外側から透視し難かったり、その存在を被覆部の外側から認識し難かったりする。 The body fluid absorbing part in the disposable pants-type diaper according to the present invention has both ends joined to the inner surfaces of the front waistline area and the back waistline area of the covering part, while the part between both ends is at least part of the center part and both sides Since the portion is in a non-bonded state with respect to the inner surface of the crotch region of the covering portion, a gap may be generated between the non-bonded portion and the covering portion. Further, the cover portion elastically contracts in the lateral direction, whereby a gather is formed on at least one of the outer surface and the inner surface. Therefore, in the crotch region of the diaper when the covering portion is in the contracted state, the body fluid absorbing portion is seen through from the outside of the covering portion due to the gap between the covering portion and the body fluid absorbing portion and the gathers formed in the covering portion. or hardly, or hardly recognize the existence from the outside of the cover portion.

伸展おむつ１１０において、前胴回り域１２と後胴回り域１３と股下域１４とを有する被覆部１５は、横方向Ｂでの弾性的な伸長と収縮とを反復可能な一枚のシート状部材３０を含んでいて、図１においては、そのシート状部材３０が弾性的に収縮した状態にある。被覆部１５では、股下域１４の両側縁部１４ｂに位置する脚回り弾性部材１１が脚回り開口１７の周方向において弾性的な伸長と収縮とを反復することができて、おむつ１０が着用されたときには、脚回り開口１７の周縁部が着用者の脚回りに弾性的にフィットする。それゆえ、股下域１４の内面に対して非接合状態にある体液吸収部２０の後記側部２０ｂは、脚回り開口１７の外に出るということがない。被覆部１５と脚回り弾性部材１１とは、互いに伸長状態にあるときにホットメルト接着剤を介して接合される。
In the extended diaper 110, the covering portion 15 having the front waistline region 12, the rear waistline region 13, and the crotch region 14 includes a single sheet-like member 30 that can repeat elastic expansion and contraction in the lateral direction B. In FIG. 1, the sheet-like member 30 is in an elastically contracted state. In the covering portion 15, the leg-hole elastic member 11 located at both side edges 14 b of the crotch region 14 can repeat elastic expansion and contraction in the circumferential direction of the leg-hole opening 17, and the diaper 10 is worn. When this occurs, the peripheral edge of the leg opening 17 fits elastically around the wearer's leg. Therefore, the side portion 20 b of the body fluid absorbing portion 20 that is not joined to the inner surface of the crotch region 14 does not go out of the leg opening 17. The covering portion 15 and the leg-hole elastic member 11 are joined via a hot melt adhesive when they are in an extended state.
