Description
一方、特許文献２に開示の着用物品においても、刳り抜いた排泄物受容域と他の領域との間に凹凸の高低差が形成されて着用感が低下するおそれがあるとともに、排泄物受容域は吸収体が存在していないことから、それ自体に吸収性がなく、排泄物受容域に受容された液体の排泄物を吸収・保持することができない。また、このように排泄物受容域を刳り抜いて形成する場合には、吸収体が所要の厚さ寸法を有する必要があり、比較的に肉厚となって、下着の外面にその外形線が表れて外観を損ねるおそれがある。 On the other hand, even in the worn article disclosed in Patent Document 2, there is a possibility that a height difference of unevenness may be formed between the hollowed out excrement receiving area and another area to reduce the wearing feeling, and the excrement receiving area may be deteriorated. Since there is no absorber, it is not absorbent by itself and cannot absorb and retain the liquid excrement received in the excrement receiving area. In addition, when the excrement receiving area is hollowed out and formed in this way, the absorber must have the required thickness dimension, and it becomes relatively thick, and its outer line is formed on the outer surface of the underwear. It may appear and spoil the appearance.
本発明に係る着用物品は、以下の好ましい実施態様を有する。

（８）前記着用物品の前記縦方向の寸法を２等分する横断中心線をさらに有し、前記排泄物受容域が前記クロッチ域において前記横断中心線に関して前記前ウエスト域側又は前記後ウエスト域側に偏位して位置し、前記第１吸収部が、前記排泄物受容域の前記横方向の外側において前記縦方向へ延びる第１及び第２縦断部分と、前記排泄物受容域の前記縦方向の外側において前記横方向へ延びる横断部分とを有し、前記横断中心線へ向かって凹となる形状を有する。かかる場合には、第１吸収部が、排泄物受容域内の排泄物がクロッチ域側から前ウエスト域のウエスト開口側又は後ウエスト域のウエスト開口側へ移動するのを抑制する障壁として機能しうる。
（９）前記第１吸収部は、前記第１及び第２縦断部分のみ又は前記横断部分のみから形成される。かかる場合には、第１吸収部が、排泄物受容域内の排泄物が横方向の外側又は縦方向の外側へ移動するのを抑制する障壁として機能しうる。
（１０）前記前後ウエスト域のうちの少なくとも一方のウエスト域を保持するためのホールド域をさらに有し、前記排泄物受容域は、前記ホールド域よりも前記縦方向の内側に位置し、前記ホールド域と重なっていない。かかる場合には、ホールド域によって排泄物受容域が着用者の身体へ押し当てられて受容スペースが崩れるのを抑制することができる。
（１１）前記表面シートの前記肌対向面側において、前記縦方向へ延びる一対のバリアカフをさらに有し、前記バリアカフは、前記表面シートの肌対向面側に倒伏された状態において縦方向へ延びる内側縁部を有し、前記排泄物受容域は、前記バリアカフの前記内側縁部間に配置され、前記内側縁部とは重なっていない。かかる場合には、排泄物受容域の収容容量を超えて吸収・保持することができなかった排泄物が横漏れするのを効果的に抑制することができる。
（１２）体液の吸収前における前記排泄物受容域の前記厚さ寸法と前記周辺域の前記厚さ寸法との差が、１．５ｇｆ／ｃｍ２荷重下における前記表面シートの厚さ寸法よりも小さい又はそれと同等である。かかる場合には、着用補助者が、使用する前に、着用物品の肌対向面側を撫でるように触れたときに感触として排泄物受容域の存在域を確認することができる。
（１３）前記排泄物受容域は、肌対向面側又は非肌対向面から視認可能な着色部分を有する。かかる場合には、着用者及び着用補助者に対して排泄物受容域を認識させ、排泄物の横漏れや排泄物の身体への付着に対して安心感を与えることができる。

In such a case, the compression recess exerts the effect of drawing in the required body shape, and the rigidity of the excrement receiving area does not become too high, which does not give the wearer a sense of discomfort.
(6) An adhesive is applied to a portion of the inner surface of the surface sheet that faces the compression recess in the excrement receiving area in the thickness direction. In such a case, the surface sheet can be deformed in a concave shape along the compression recess even when the compression recess is formed only in the absorber, and the outline of the excrement receiving area becomes clearer before wearing. Can be visually recognized.
(7) The peripheral area includes a first absorbing portion located along at least a part of the outer peripheral edge of the excrement receiving area, and a second absorbing portion extending outward from the outer periphery of the first absorbing portion. The content of the super-absorbent polymer particles in the first absorption portion is higher than the content of the super-absorbent polymer particles in the second absorption portion. In such a case, after the body fluid is absorbed by the absorber, the superabsorbent polymer particles swell and the first absorbing portion becomes thicker than the second absorbing portion, so that the first absorbing portion and the excrement receiving region become thicker. A larger receiving space is defined between them.
(8) It further has a transverse center line that further divides the vertical dimension of the worn article into two equal parts, and the excrement receiving region is the front waist region side or the rear waist region with respect to the transverse center line in the crotch region.

It has a crossing portion extending in the lateral direction on the outside of the direction, and has a shape concave toward the crossing center line. In such a case, the first absorbing portion can function as a barrier for suppressing the movement of excrement in the excrement receiving area from the crotch area side to the waist opening side of the anterior waist area or the waist opening side of the posterior waist area. ..
(9) The first absorbing portion is formed only from the first and second longitudinal portions or only the crossing portion. In such a case, the first absorbing portion can function as a barrier for suppressing the movement of excrement in the excrement receiving area to the outside in the horizontal direction or the outside in the vertical direction.
(10) It further has a hold area for holding at least one of the front and rear waist areas, and the excrement receiving area is located inside the hold area in the vertical direction and holds the hold. It does not overlap with the area. In such a case, the hold area can prevent the excrement receiving area from being pressed against the wearer's body and the receiving space from collapsing.
(11) The surface sheet further has a pair of barrier cuffs extending in the vertical direction on the skin-facing surface side, and the barrier cuffs are inside extending in the vertical direction in a state of being laid down on the skin- facing surface side of the surface sheet. It has an edge and the excrement receiving area is arranged between the inner edges of the barrier cuff and does not overlap with the inner edge. In such a case, it is possible to effectively suppress the lateral leakage of excrement that could not be absorbed and retained beyond the capacity of the excrement receiving area.
(12) The difference between the thickness dimension of the excrement receiving area and the thickness dimension of the peripheral area before absorption of the body fluid is larger than the thickness dimension of the surface sheet under a load of 1.5 gf / cm 2. Small or equivalent. In such a case, the presence area of the excrement receiving area can be confirmed as a feeling when the wearing assistant touches the skin-facing surface side of the worn article as if stroking it before use.
(13) the excrement receiving zone, also skin-facing side having a colored portion visible from the non-skin-facing surface. In such a case, it is possible to give to recognize the excrement receiving area for the wearer and wearing for auxiliary person, a sense of security with respect to attachment to the body of the lateral leakage and waste of excrement.

Next, after immersing the absorber in a pad containing 120 g of artificial urine with the side facing the skin facing downward to uniformly absorb the artificial urine (the amount of liquid retained is 30% or more), the SAP particles are sufficiently added. It was allowed to stand for 5 minutes to swell. After 5 minutes, the thickness dimension (mm) was measured with a thickness gauge for each of the excrement receiving area, the first absorption part of the peripheral area, and the second absorption part of the peripheral area, and after absorption of artificial urine. The thickness dimension of each region in. For the artificial urine, for example, ion-exchanged water, urea, sodium chloride, magnesium sulfate, calcium chloride and a dye (blue No. 1) prepared in an arbitrary ratio were used.
このように、周辺域５１の第１吸収部が前ウエスト域１１側に位置する場合であっても、第１及び第２縦断部分５２Ａ，５２Ｂ並びに横断部分５２Ｃのうちの少なくとも１つの部分が配置されていればよい。第１吸収部が第１及び第２縦断部分５２Ａ，５２Ｂのみ又は横断部分５２Ｃのみから形成されている場合においては、排泄物受容域５０が後ウエスト域１２側に位置する場合と同様の排泄物の流動を阻止する障壁としての効果を有する。特に、排泄物受容域５０が前ウエスト域１１側に位置する場合において、第１吸収部が横断部分５２Ｃを有する場合には、それが障壁となって、クロッチ域１３側から排泄物受容域５０に進入した排泄物がさらに前端部１６へ向かって流動し、着用者の腹部を汚すのを抑制することができる。 In this way, even when the first absorbing portion of the peripheral region 51 is located on the front waist region 11 side, at least one portion of the first and second longitudinal portions 52A and 52B and the crossing portion 52C is arranged. It should be done. When the first absorption portion is formed of only the first and second longitudinal portions 52A and 52B or only the transverse portion 52C, the excrement receiving area 50 is the same as the case where the excrement receiving area 50 is located on the posterior waist area 12 side. It has the effect of blocking the flow of water. In particular, when the excrement receiving area 50 is located on the anterior waist area 11 side, when the first absorbing portion has the transverse portion 52C, it becomes a barrier and the excrement receiving area 50 from the crotch area 13 side. It is possible to prevent the excrement that has entered the body from further flowing toward the front end portion 16 and contaminating the wearer's abdomen.
吸収体２５の周辺域５１全体にも複数の圧縮凹部７０が形成されていることによって、周辺域５１は圧縮凹部７０が配置されていない場合に比べて比較的に剛性が高くなり、着用中における吸収体２５全体のよれがさらに抑制され、周辺域５１に囲まれた排泄物受容域５０が外力によって変形するのをさらに抑制することができる。 Since a plurality of compression recesses 70 are also formed in the entire peripheral region 51 of the absorber 25, the peripheral region 51 has a relatively high rigidity as compared with the case where the compression recesses 70 are not arranged, and is worn during wearing. The twist of the entire absorber 25 is further suppressed, and the deformation of the excrement receiving area 50 surrounded by the peripheral area 51 by an external force can be further suppressed.
図９（ｂ）を参照すると、吸収体２５の体液吸収後の状態において、ＳＡＰ粒子の含有率が、周辺域５１の第１吸収部５２≧周辺域５１の第２吸収部５３＞排泄物受容域５０となっていることから、ＳＡＰ含有率に応じて各領域５０，５１の厚さ寸法Ｄ１，Ｄ２，Ｄ３が変化しており、周辺域５１の第１吸収部の厚さ寸法Ｄ２≧周辺域５１の第２吸収部５３の厚さ寸法Ｄ３＞排泄物受容域５０の厚さ寸法Ｄ１となっている。 Referring to FIG. 9B, in the state after the body fluid is absorbed by the absorber 25, the content of SAP particles is such that the first absorption portion 52 in the peripheral region 51 ≧ the second absorption portion 53 in the peripheral region 51> excrement. Since the receiving area is 50, the thickness dimensions D1, D2, and D3 of each of the regions 50 and 51 change according to the SAP content, and the thickness dimension D2 ≧ of the first absorbing portion of the peripheral region 51. The thickness dimension D3 of the second absorbing portion 53 of the peripheral region 51> the thickness dimension D1 of the excrement receiving region 50.
